Vinson, Ottumwa, Iowa Application November 3, 1936, Serial No. 108,991 7 Claims. (01. 70-146) The object of my invention is to provide a l4 and the outer wall I! and the‘keeper l6 be door latch and lock structure, particularly adapt tween them. ed for use on motor vehicles. ' For greater convenience in manufacture and More especially, it is my purpose to provide installation, a greater part of the latch mecha a lock and latch, which is primarily adapted for nism is supported on a metal plate l1, which use with pleasure vehicles. when installed is designed to be mounted against Another purpose is to provide such a structure the outer surface of the inner wall Ill. When I having a handle designed to be on the outside here speak of outer surface, I'mean that surface for instance of an automobile door, which can which is toward the outside of the car. 10 .be locked in position and which will leave the The plate I‘! has at one end‘ the ?ange l8 ex 10 latch bar free for operation from the inside of tending at right angles. This ?ange l8 has an the car. _ v opening l9 through which the beveled latch , Another purpose is to provide such a structure in which the outside handle can be locked either from outside the car or from the inside of the car, and yet which will permit the latch bar to still be operated from the inside of the car. Another object is to provide a structure in which, the outside handle is arranged in a coun tersink in the door, so it will not catch on cloth ing. A further object is to provide a number of improved details in structure of a latch and lock mechanism. . - With these and other objects in view, my in vention consists in the construction, arrange ment and combination of the various parts of my door latch and lock structure, whereby the 30 objects’contemplated are attained as herein after more fully set forth, pointed out in my claims and illustrated in the accompanying drawing, in which: ' _ Figure 1 is a horizontal, sectional view ofa tip 20 is extended. The latch tip 20 has the or dinary latch bolt 2|, which near its end farthest from the latch tip 20 slides through a yoke 22 on the plate l1. . From now on, I shall describe the structure as though the plate I‘! were in its vertical posi tion as installed as illustrated for instance in Figure 1, and shall treat that face of it ‘which is toward the outside of the car as its outer face. Extending outwardly from this outer face is an upper angle bracket 23. Similarly extending out wardly from the outer face of the plate I‘! is a lower angle bracket 24, the outer end of which as indicated at 25 in Figure 2 is offset slightly to ward the bracket 23. This offset is merely for the purpose of affording proper clearance for the various parts. The latch bolt 2| rests just above the bracket 24, as perhaps best illustrated in Figure 4, and may even slide thereon. The latch bolt, 2| as shown in Figure 6 has an outwardly projecting portion of a car door equipped with a latch and ' arm 26. . lock structure embodying my invention. I provide a handle which is indicated general Flgure 2 is a front elevation of the latch and lock structure. . Figure 3 is a detail, sectional-view taken on the line 3-2 of Figure 1. 40 Figure 4 is a detail, sectional view taken on the line 4-4 of Figure 1. _ ‘ Figure 5 is a view similar to, that of Figure 4 illustrating the parts in another position; and Figure 6 is a detail, sectional view taken on . the line 6—6 of Figure 2. In the accompanying drawing, I have used the reference character A to indicate generally an automobile door or the like and the character B to indicate the body of the car. Since most pleasure cars are now made‘ of metal, I have shown that type of structure in my drawing. The door A has the inner wall "I and the outer wall I! connected by the closure wall I! at the edge of the door. Similarly the car body B has theinner wall 55 ly at C, and which is in the‘ form of a bell crank lever, with the handle portion 21 and the arm portion 28. The handle C is pivoted on a pintle or the like 29 between the outer ends of the brackets 22 and 24 with the arm 28 projecting generally in'the direction of the plate I‘! and the handle portion 21 projecting generally to the right from the pintle 29 when the parts arein the position shown in Figure 1. a i It should be mentioned perhaps that the wall vl2 is provided with an indentation or counter sink ” which receives the handle 21 when the latter is in its normal position. The handle is tensioned toward this normal ‘position by means of a spring 3|, which has a coil mounted on the pintle 29 and one am engaged with the bracket 24 and the other arm engaged with the arm 20 (see Figures 1, 2 and 3). The handle 21 can be pulled from its normal 45 2,106,954 2 full line position shown in Figure 1, when it is substantially received within the recess 38 out wardly to its dotted line position shown in Fig ure 1. This swings the arm 28 to the right to its dotted line position shown in Figure 1. In the inner part of the arm 28 is mounted a slidable bolt 33 actuated by a locking mechanism 34 of any di?erential type. The slidable bolt 33 when in its retracted position stands just to the left of the arm 28 on the latch bolt 2| when the latter is in locking position. The latch tip 20 and latch bolt 2| are spring pressed toward locking position by means of a spring 35. ' ~ The bracket 24 has a hole 36 in line with the. 15 slidable bolt 33, and by actuating the lock mecha nism 34 and sliding the bolt 33 from its position shown for instance in Figure 4 to its position shown in Figure 5, the end of the slidable bolt 33 20 may be projected through the hole 36, whereupon the handle can not be actuated. On the other hand, when the slidable bolt 33 is in its retracted position, illustrated in Figure 4 and in Figure 3, the swinging movement of the 25 handle 21 from its full line position shown'in Figure 1 to its dotted line position shown in that ?gure, causes the slidable bolt 33 to engage the arm 26 (see Figures 3, 4 and6) for-retracting the latch tip 20 and latch bolt 2| for unlocking 30 the door. , ’ The spring 3| tends to return the handle to its normal position whenever the grasp of the oper ator is released, and the spring 35 then serves to return latch and latch bar to locking position. Connected to the latch bolt 2| is a link 38 shown 36 for instance in Figures 1 and 2. This link has an elongated slot 39 slidably mounted on a pin 48 on the latch bolt 2|. It is intended to be con nected with any door opening structure oper 40 able fromthe inside of the car, which structure is not here of any special importance. On account of the fact that the pin 40 slides in the slot 39, the mechanism here shown may be 45 outwardly from its position shown in Figure 1 for instance to its dotted line position in that ?gure will be resisted by engagement of the arm 28 with the ?ange 45 (see Figures 1 and 4). The locking member F may be manually oper ated by means of. a pin 48 secured to the plate 43 and extending through a curved slot ,43 in the plate I‘! and through a suitable slot 58 in the inner wall In of the door, and having on its outer end the head 8|. The material around the slot 50 10 is arranged to coact with a spring 52 on the pin 48, so that the pin will be frictionally held in any position to which it may be adjusted. When the latch member F is thus manually operated to any position, it can, of course, be 15 manually operated from the inside of the ear to any other position. It will be noted that regardless of the position of the latch member F, the latch tip 23 and latch bolt 2| can be freely operated by means of the 20 link 38. Thus the door can be unlatched from inside at any time. 1 Ii’, however. the latch member F has been moved to locking position, and it is desired to unlock the door from the outside, the key is 25 turned in the lock‘device 34 and the bolt 33 is ?rst moved to its extended position shown in ' Figure 5 for engaging the ?nger 41 and moving the member F to unlatching position, and is then retracted, whereupon the, handle 21 can be freely 30' operated for opening the door. If it is desired to lock the door from the out side, the key is turned to position for movingthe bolt 33 into the opening 36 and the parts are then left in this position. It is then impossible to 35 open the door from‘ the outside. The projection of the bolt 33 through the opening 38 looks the arm 28 and the handle 21 against door unlatching movements The door can not then be unlocked from outside without using a key for retracting 40 the bolt 33. It will thus be seen that I have provided a operated without operating the link 38. The lock rather simple lock structure, providing for the arrangement of the handle 21 normally in posi mechanism 34 is not shown in detail and any suitable mechanism might be employed for mov the garments of those who get into and out of ing the slidable bolt 33 lengthwise.- As here .shown, the cylinder of the locking mechanism 34, is mounted to rotate and has on its inner end an off-center pin 4|, extending lengthwise of the 50 cylinder and at right angles to the slidable bolt 33. The slidable bolt 33 has a groove 42 into which the pin 4| projects. These parts are so arranged 55 that when the cylinder of the lock 34 is rotated, the slidable bolt 33 will be moved lengthwise. I have also provided a separate means for look ing the latch from the inside of the car. This is of peculiar shape and is shown at F for in 60 stance in Figure 4. It consists of a plate portion 43 pivoted at 44 on the plate ‘l1. Projecting from one edge of the plate portion 43 is a ?ange 45. Projecting downwardly from one end of the ?ange 45 at the outer edge thereof is a hook-like mem tion in the recess 38, where it will not catch on 45 the car. I Y The door can be unlatched and opened by pulling the handle 21 outwardly to the dotted line position shown in Figure 1 .for unlatching, 50 and then ‘continuing the pull for swinging the door open. . ' When the bolt 33 of the lock is retracted, it will coact with the arm 28 for unlatching the door, and when the parts are in-proper position, 65 and it is projected through the hole 38, the han dle mechanism can not be worked. Yet even then the latch bolt 2| can be operated from the inside 0! the car. The structure is such that the latch member F can be manipulated from inside the car for moving it to position shown in Figure 4, where it will prevent any door opening movement oi.’ the handle 21 and yet does not interfere with ' 65 ber 46, having the ?nger 41. The parts of this locking device F are so ar the unlatching of the door from the inside. Changes may be made in the construction and ranged that when they are in neutral position shown in Figure 5 they have no effect upon the operation of the device, but when theyare swung 70 from the position of_ Figure 5 to the position of Figure 4, then the ?nger 41 projects through the cover by my claims any- modi?cations in struc 70 ture or use of mechanicalequivalents, which may‘ 76 arrangement of my lock, and its parts and in the materials used, and the shapes and sizes 0! the various elements,.and .it is my intention to hole 36 in the bracket member 24, as shown in be reasonably included within the scope of my Figure 4, and the ?ange 45 stands behind the inventionyand of my claims. . arm 28, so as to prevent latch opening movement I claim: of that arm.
