Application October 19, 1936, Serial No. 106,396 18 Claims. (Cl. 290-38) This invention relates to engine starting, and ing motor circuit there is a second switch which 5 particularly to an engine starting control for internal combustion engines in motor vehicles. The engines in motor vehicles are almost uni for convenience (though not necessarily) may be coupled with the ignition switch for the engine sure of the circuit energizing the motor which turns over the engine until it starts and runs in its inner switch closing position, and then on turning the ignition key the starting motor would which is mounted on the dash so that in start versally started by an electric starting motor > ing the engine the starting button or member would be pushed inwardly, it remaining locked which is in a circuit including a battery, the clo under its own power, after which there is an auto 10 matic disconnection of the driving connection be— tween the starting motor and the engine. One method of closing the starting motor cir cuit is to use a starting pedal which is foot oper ated, usually by the right foot of the driver leav 15 ing the left foot to actuate the clutch pedal to disconnect the clutch. Another method is to use the right foot to depress the accelerator pedal, such depression of the accelerator pedal closing the starting circuit until the engine has started, whereupon through engine operation the start ing motor electric circuit is broken and the start immediately proceed to turn over the engine, leaving the hands free for whatever manipula 10 tion of throttle and choke controls might be needed, and also leaving the right foot free to depress the accelerator pedal in order to get a greater volume and control the volume of fuel mixture going into the engine at starting, as is 15 very desirable. It is a further object of the invention to pro vide means such that as soon as the engine starts the lock which has held the starter mem— her in its switch closing position is automatically released, the starter member returned to its original position, the switch opening to stop the starting motor. And simultaneously with such ing motor thereupon stops. When a foot operated starter pedal is used to close the starting motor circuit, the foot pressure is continuous as release release of the lock a second lock comes into play of the foot pressure breaks the electric circuit whereby the starting member for closing said so that the starting motor does not operate. In ‘switch cannot be pressed inwardly during the some cases the starting pedal which is foot oper major portion of the time that the engine is ated is replaced by a starting button on the dash running, thereby insuring against the gear clash of the automobile which is pressed inward by the which frequently occurs because the driver or 9.0 hand of the operator and pressure maintained the car, with present modern day engines which thereon‘ until the engine has started, the same as are almost noiseless at low speeds, many times foot pressure is maintained on the starter pedal. thinks the engine has stopped when it has not, This occupies one hand, the right hand if the and thereupon steps on the starter pedal or starting button on the dash is to the right of the pushes in the starter button. With the present steering wheel, or the left hand if it is to the left invention this cannot occur particularly at those 35 hand end of the dash. In such latter case the speeds of the engine when its noise of running is handling of the starter button is awkward, and to low. maintain the pressure with the left hand and at The present invention is directed to a very the same time to do such manipulation of the simple, economically produced, readily assembled throttle and choke controls as may be desirable and installed mechanism‘ for the attainment of 40 is not satisfactory; while if the right hand is the objects stated, together with numerous others used to operate the starter, control of the choke not at this time speci?cally stated, but which will and throttle is not possible. For these reasons appear upon understanding of the invention, the foot operated starter pedal is used to the which is set forth in the following description. much greater extent. taken in connection with the accompanying draw In the present invention the starting control ings, in which, member is preferably mounted on the dash of the Fig. 1 is a fragmentary side elevation illus automobile, though it can be mounted quite as trating the mounting of the starter device on the well at the floor or front of the driving compart dash of an automobile and showing its connec ment of the automobile and would work in the tion with the manifold of an engine for the same manner.

Like reference characters refer to like parts in the ?gures of the drawings. 30 The engine I is an internal combustion engine of a conventional type having an intake mani fold 2 through which the fuel mixture passes from the carbureter to the engine cylinders. The electric starting motor is indicated at 3 having 35 on its shaft a pinion 4 which couples with a gear on the ?y wheel of the engine to turn the engine over in the operation of starting. The automo~ bile body has the usual cowl members 5 and 5a, the windshield frame 6 at the rear part of the 40 portion 8a, and with a depending dash 1 below the windshield as is usual. In the present invention as shown in Figs. 1 and 2, a support is made from a single length of flat bar material bent into the shape best shown in Fig. 2. It includes a vertical section 3 which is adapted to be placed against the rear side of the dash ‘I and secured thereto. From the upper end of the section 8 a relatively long horizontal section 8 is bent to extend forwardly. terminating in a vertical arm III at its front end. At the lower end of the section 8 a second and shorter horizontal section II is bent at right angles to extend forwardly and terminates in an upwardly turned vertical arm l2 at its forward end which extends toward the section 8. At the underside of the horizontal section 8 a distance in front of the arm I2 an angle member having a horizontal leg I3 is spot welded or attached by screws or otherwise permanently secured to the 60 section I2, from which leg i3 a vertical leg l4 extends downwardly in substantial parallelism to the parts 8 and I2 and spaced a distance ahead of arm l2. A binding post I! is secured to and electrically 65 insulated from the leg l4 to which one wire i8 of the electric circuit is connected. A movable spring switch member i1 is fastened at one end to the binding post I! having its free end dis posed over and normally spaced from a contact 70 member and binding post I8, which is likewise secured to and electrically insulated from the leg l4 near the upper end thereof. To the member II a second wire l8 of the electric starting circuit is connected. 78 The wire l8 leads to an electric battery and in its length is preferably associated with a second switch 20. As shown ‘in. Fig. 1, dotted lines 2| are shown to indicate that either the wire it may lead to a second switch 23 disposed in the length thereof or go directly to the battery. The first described structure is preferable. This switch 20 interposed in the length of the wire l8 may for convenience be associated with and operated by the same key as the ignition switch for the engine. The wire it connects to the 10 battery 22 at one pole, the other pole of the battery being connected to a suitable ground 23. The wire I 8 leads to one pole of the electric starting motor 3 and the other pole of the electric motor is suitably grounded as indicated, the dia 15 grammatic indication being a wire 24 grounded at 28. A switch closure member to move the. switch II to close the break between the wires i 8 and i 8 is mounted for slidable movement through the section 8 and the arm i2. This member com prises a rod 28 which, at its upper side, has a vertically extending rib or tongue 21 with vertical shoulders 28 and 29 at the opposite ends of the rib disposed above the rod 25. The rod 28 passes through the dash ‘I and at its outer end has a knob or button 30 attached thereto, for example, by threading the same onto the outer end of the rod 26. A coiled spring 3| is located around the outer end of the rod 28 and bears at one end against the inner side of the knob 30 and at its other end against the bottom of the sheet metal cup 33 which is continued in a skirt or escutcheon 24 as shown in Fig. 2. Therefore, normally under the in?uence of the spring 3i the rod 28 is moved 35 to the left, in Fig. 2, so that the outer side of the knob 30 lies substantially flush with the outer end of the cup 33'. A pin 32, or any other equiva lent stop may be used to limit the outward move ment of the knob 38 and the rod 26 attached to it. 40 As shown in Fig. 2 the pin 32 passes through the rod 26 and comes against the inner side of the section 8 in the position of the parts which they occupy when the engine is at rest. On the upper side of the horizontal section 8 45 of the support a post 35 is located and perma nently secured in any manner. A lever of in verted T-form is pivotally mounted at the upper end of the post 38 having a vertical arm 36 and two oppositely extending horizontal arms 31 and 38 at its lower end. The arms 31 extends toward the dash ‘I and at its free end has a bar 38 piv otally connected. The bar passes downwardly through a guide opening in the section 3 and at its lower end is adapted to rest against the upper end or surface of the rib 21 when the engine is at rest. The other arm 38 has a like bar 48 pivotally connected to and depending therefrom which likewise passes through a guide opening in the section 9, with its lower end in the position 60 of the parts shown in Fig. 2 when the engine is at rest being in a plane slightly above the upper edge of the rib 21. A rod 4| is pivotally connected at one end to the upper end of the arm 36 and at its other end has a secure connection to a ?exible diaphragm 42 which is sealed at the open side of a dia phragm casing 43. At the center of the back of the casing 43 a short tubular sleeve 44 is made soldered or otherwise permanently secured to a 70 coupling sleeve 45. The sleeve 45 passes through an opening made for it in the arm I U and is threaded exteriorly so that a binding nut 48 may securely clamp the diaphragm unit in place. A tubing 41 is secured to the outer end of the 75 2,122,088 sleeve 45 by a nut 48 as shown, and at its for ward end is connected with the manifold 2. A coiled compression spring 49 is disposed between the central part of the diaphragm 42 and the bottom of the diaphragm casing 43. ' With the parts in the position shown in Fig. 2, as when the engine is not operating, the force of spring 49 causes the bar 39 at its lower end to bear with some pressure against the upper edge of the "10 rib 21 adjacent the shoulder 28. When the en gine is to be started the driver pushes inward on the knob 39 compressing the spring 3|. .The in ner end of the rod 29 engages the movable switch member l1 and presses it against the contact at 15 I8. When this occurs the shoulder 28 will have passed beyond the forward side or edge of the bar 39 whereupon the spring 49 turns the T shaped lever in a counter-clockwise direction and the lower end of the bar 39 comes ‘behind the shoulder at 29 thereby locking the parts in posi tion to hold the switch member l‘I in circuit clos ing position. With the preferred form of struc ture the engine will then immediately start as soon as the ignition key is turned to close igni tion switch and simultaneously complete the cir cuit through the electric motor. When the en gine starts there is a falling of pressure within the manifold 2 below atmospheric pressure which results in a pressure upon the outer side of the diaphragm 42, compressing the spring 49, mov ing the rod 4| lengthwise in a forward direction and turning the T-shaped lever‘ in a clockwise direction. This elevates the bar 39 above the shoulder 28 releasing the rod 26 which returns to its initial position under the influence of spring 3|. The clockwise movement of the T shaped lever lifts the bar 39 to a position higher than that shown in Fig. 2 and simultaneously lowers the bar 49 to a‘ lower position than that 40 shown, or in front of the shoulder 29. As long as the parts remain in such position it will be im possible to manually move the switch closing member 26 forward as the bar 49 will interpose a stop against such movement when the shoulder 45 29 strikes against it. Therefore, after the engine has started and is running under its own power, closing the starting motor circuit is impossible so long as the vacuum within the manifold 2 remains sufficiently high. At times under heavy loads 50 and with wide open throttle the vacuum greatly 3 switch like or equivalent to the switch 29 in the circuit to take care of those conditions where ir respective of the turning over of the engine by the starting motor the engine does not start. If there was no second switch to be operated to interrupt the starting motor circuit the starting motor, under such conditions, would continue to run until the battery was exhausted. With the construction a control of the fuel volume going to the engine at starting is readily obtained, the driver not having to use a foot for the starter pedal so that he can use the same upon the ac celerator pedal. The locking in of the starting member leaves the hands of the driver free for other acts which may be desirable in starting 15 the engine such as shifting the choke or throttle controls back and forth while the starting motor is turning the engine over. It also obviates any awkward positions of the driver which would be required if one hand was to be used to hold the 20 starter switch in closed position and the other was used to manipulate the throttle and choke controls. While the switch at 29 is indicated as built in connection with the ignition switch of the engine, 25 it is quite evident that if desired the second switch in the electric starting circuit may be wholly independent of the ignition switch. The second switch either independent of or joined in connection with the ignition switch so as to be 30' closed simultaneously with the closing of the ig nition switch is a matter of choice, the operation of the device being the same in both cases. In Figs. 3 to 6, inclusive, a form of construction is illustrated of a design more applicable for com 35 mercial production. The support is of a sub stantially cylindrical form made, preferably, from a single length of sheet metal which is shaped to provide an upper half 59 and a lower half 5|, each of semi-cylindrical form, and connected at 40 their rear ends by an integral section 52, where by a connecting member 53 may be inserted be tween the rear ends of the semi-cylindrical sec- tions, 59 and 5|, and the part 53 and clamped in place when the free end portions of parts 59 and 45 5| are brought together. Said free end portions are connected with a ?anged substantially cup like member 54 which, at its upper side, has an extension bar 55 integral therewith, on which the diaphragm casing is shown mounted in Fig. 2 50 on the arm I9. Tongues 56 extend from the free case the spring 49 would move the parts to the . ends of the parts 59 and 5|, and are passed diminishes or substantially disappears in which 55 60 65 70 75 position shown in Fig. 2 even with the engine running and it would be possible under such con dition of engine'operatlon to close the circuit. At such times, however, there is no question in the mind of the driver but that the engine is running and there is little probability of any at tempt to operate the starter knob 39 under such conditions. When the engine is running at nor mal speeds and under normal conditions or when it is running at lower speed so that its operation is almost silent then the lock against operating the switch closing member is effective. The construction described is very economical to produce, and is very quickly and easily assem bled and installed. In the operation of starting an engine in a motor vehicle with the structure described, the driver may push inward on the knob 39, throw out the clutch, step on the ac celerator pedal to depress it a desired‘ amount, if an automatic choke is not used he can set the choke at what appears to be the desired position then turn the ignition key and the engine will start. It is very desirable that there be a second through openings in the parts 54 and, 55 being bent over as shown in Figs. 3 and 4 to securely connect the parts together and maintain the 55 housing support in cylindrical form. The cup-like member 55 has an opening there through surrounded by an outwardly extending flange 51, through which opening the circuit wires l6 and I9 pass. The wires are connected 60 with opposite contacts 58, screws being used to secure the wires in electrical connection with the contacts and secure the contacts to insulating blocks 59, one of which is mounted on each of the members 59 and 5| of the housing; so as to diametrically oppose each other in accordance with the construction shown in Fig. 3. Screws 69 with washers underneath the same secure the insulating blocks to the parts 59 and 5| of the housing support. 70 Intermediate the ends of the cylindrical hous ing support thus provided, the metal is pressed outwardly to make a continuous rib 6| thereby providing a continuous annular groove within the housing member. A ring 62 is mounted 75 4 9,129,088 therein, having an arm 53 extending upwardly through an opening in the upper-member 50 of the housing. Said arm 53 is equivalent to the break in the electric circuit between said contacts 58. Upon the engine starting the pressure of air against the outer side of the diaphragm causes - supporting bracket 25 in the structure shown in the inverted T-shaped lever to be swung in a clockwise direction lifting the bar 39 and releas ing the switch closing member to return to the position shown in Fig. 3 under the force of spring 10 until stopped by the end of the body 61 engag ing against the collar 66. The air pressure Fig. 2, and at its upper end the inverted T-iever having arms I5, 81 and 28 is pivotally mounted in the same manner. The bars 28 and 40 con nected respectively to the ends of the arms 31 and 88 extend downwardly through guide sleeves 10 84 and openings made in the upper side of the upper member 5|! of the housing, as shown. The metal of the housing parts 50 and 5| is also'formed with second outwardly pressed ribs 65 to provide a continuous annular groove within 15 the housing in which the peripheral portions of a collar 68 are adapted to be seated and held._ Within the housing a switch closing member is mounted for longitudinal movement. It in cludes in its structure an intermediate body 20 member 61 of substantially cylindrical form and with an exterior diameter slightly less than the interior diameter of the cylindrical supporting housing. A member having a head 58 of sub stantially the same diameter as the body 81, and 25 with a reduced stem 59 is connected with one end of the body 61 in any suitable manner, such as by the screw connection shown, the collar 65 being located around the stem 69 and a coiled compression spring 10 located around the stem and bearing at its opposite ends against the col lar and the inner end of the head 88 as shown. The shoulder at the end of the body 61 where it connects with the stem 59 engages against the collar 58 when free to do so, the spring 10 being 35 under compression so as to normally move the switch opening member to the left. 'In the po sition of the parts shown in Fig.3, the bar 59 is a short distance from such shoulder but when the head 88 is engaged so as to move the sw-itch 40 closing member to the right (Fig. 3) the bar 39 at its lower end will move downwardly until its lower end engages the stem 59 and the spring ‘Ill cannot move the switch closing member in the opposite direction until bar 39 has been lifted. 45 This secures the same result as when the bar 26 in the structure shown in Fig. 2 is moved to the right and the lower end of the bar 39 drops into position to be engaged by the shoulder 28. The opposite end of the body 81 is reduced in 50 diameter, as indicated at 1|, providing a con tinuous annular groove between the larger diam eter part of the body and a member 13 of insu~ lating material which is connected to the smaller diameter part ‘II. A screw ‘H is used for such 55 purpose having its head located‘ at the bottom of a relatively deep recess in the member 13, and thereafter a bridging contact 15 is screwed or otherwise permanently secured at one end in the recess with a disk of insulating material between 60 the head of the screw and the bridging member as fully shown in Fig. 3. ‘ The operation and the results thereof are the same with this structure as vthat shown in Figs. 1 and 2. The head 58 extends a distance through 65 the dash ‘I or an instrument plate carried by the dash on which the device is mounted. Pressing upon the head 68 compresses the spring ‘I0, moves the body 51 to the right and if the engine is at rest the spring 49 associated with the dia 70 phragm thereupon turns the inverted T-shaped lever in a counterclockwise direction, and the lower end of the bar 39 passes between the adja cent end of the body 81 and the collar 86. When this occurs the bridging contact 15 will have en 75 gaged both contacts 58 and closed the gap or against the diaphragm will thereupon cause the 10 lower end of the bar 40 to enter the groove at 12 and the switch closing member cannot be moved to closing position while the engine ‘is running, so long as the air pressure at the outer side of the diaphragm is su?icient to overcome the spring 15 49 and any inherent resistance of the diaphragm itself. - In assembling the parts which have been de scribed, the spring 10 and collar 55 are put upon the stem 69 and the stem and the body 61 are 20 then connected together by the screw connection shown, though, if desired, a press ?t connection would serve quite as well. The blocks 59 and contacts 58 with the wires i8 and I9 attached may be connected to the parts 50 and 5| of the 25 cylindrical housing, the wires l6 and I9 having ?rst been passed through the opening in the cup member 54. Previous to this the ring 52 may be slipped over the body 61; and, of course, the bridging contact ‘I5 with the insulating member 30 ‘I3 associated therewith would have previously been attached to the reduced end ll of the body 61. The parts 50 and 5| at their free ends may be spread apart suiliciently that the collar 66 will come opposite the grooves made by the press 35 ing outward of the ribs 65, and the arm 63 may be passed through the opening made therefor in the part 50 and thus locate the ring 62 opposite the groove in which it is adapted to be seated. The bar 53 is inserted in place and then the outer free ends of the parts 5|! and 5| oi the housing casing brought together and the attachment of the cup member 54 made as described. The in verted T-shaped member having the bars 39 and 40 connected thereto may then be pivotally con 45 nected to the outer end of the arm 63, and the diaphragm casing and the vacuum tube 41 with the connections therebetween secured to the end of the supporting bar 55, the rod 4| having been previously connected at one end to the diaphragm. 50 Then by pivotally connecting the oppositeend of the rod 4| with the vertical arm 36 the assembly is complete. The attaching member 52 and the section 52 between the parts 50 and 5| are pro vided with openings through which the head 58 55 may freely pass. In Figs. 7 and 8 a slight modi?cation is shown. In this case the cylindrical housing support will be made of two parts similar to the parts 50 and 5| but without the integral connecting section 52 60 between them. They are designed in the struc ture ‘shown in Fig. 7 to be received within a collar 16 and soldered or otherwise permanently connected therewith, the collar having oppositely extending ears ‘I’! through which screws or other i'astenings may be passed to mount the same upon the dash I. In Figs. 9, 10 and 11, at the outer ‘end of the rotatable barrel 20a of the ignition switch 20 a plate 18 is secured at one end and at its free end 70 portion is bent outwardly as shown, whereby when the barrel is turned in a clockwise direction by the key associated therewith to complete the ignition circuit the free end portion of the plate covers the exposed end of the head 68. When 75 5 2,122,088 the ignition switch is operated in a reverse direc tion to stop the engine the head 68 is uncovered as in Fig. 9. With such a construction, as shown in Fig. 11, the arm 38 and the stop bar 40 connected therewith may be eliminated and the insulating block 13 connected directly to the body 61, which body may be shortenedconsiderably in length, thereby shortening the cylindrical housing mem her. In operation the locking in of the longitudinally movable switch closing means in the cylindrical housing support by the engagement of the rod 39 ahead of the shoulder at the left-hand end of the engage with and close the switch, said rod having a shoulder thereon, means automatically movable into engagement with said shoulder when the same has been moved to switch closing position, and engine operatedmeans for withdrawing said shoulder engaging means therefrom when the en gine starts. , 4. In combination, an engine, an electric start ing motor therefor, an electric circuit‘ with a nor mally open switch in the circuit for the starting 10 motor, a longitudinally movable rod adapted to be manually operated‘to engage with and close the switch, a locking member automatically movable into engagement with the rod to hold the same in switch closing position, and means 15 body 61 will occur in the same manner as pre viously described. Engagement with the outer . operated through suction developed by the en end of the head 68 to push said switch closing gine when it starts for withdrawing said locking member to switch closing position cannot take \member from engagement with the rod to free place unless the plate 18 occupies the position the same to open said switch. 20 shown in Fig. 9, the ignition circuit not being 5. In combination with an engine, an electric 20 completed. When the ignition circuit is com starting motor therefor, a circuit with a nor pleted by turning the barrel of the ignition switch mally open switch therein for the motor, a man lock in a clockwise direction head 68 is covered. ually operable longitudinally movable rod mov After the engine starts and the'parts assume able to engage with and close the switch, spring 25 the position shown in Fig. 11 the head 68 cannot means tending to return the rod to initial posi be engaged for operation of the movable switch tion, a locking member, means on the rod with closing member except on turning 011 the ignition and stopping the engine. Accordingly there can which said locking member automatically engages when the rod is moved to switch closing position, and a diaphragm combined with means connect be no closure of the starting motor circuit while 25 30 the engine is running irrespective of the vacuum ing the diaphragm with the locking member and 30 conditions in the engine manifold. The structures illustrated in Figs. 3 to 6, in clusive, and in Figs. 9, 10 and 11 are of a practi cal commercial form. While the ring 62 has been shown as a continuous‘ ring, it is quite evident that it could be replaced by a semi-cylindrical member at the lower end of the arm 63 the ends of which would terminate at the edges of the upper housing member 50. Various other 40 changes in minor detail may be resorted to without departing from the invention.
