(01. 273-1011) ‘ My invention relates to an improvement in target ri?e ranges of the type in which a ri?e or revolver or gun or the like is'employed to shoot a ?ash or ray of - light, of short duration, at a #5. target Which includes a photoelectric cell.‘ One purpose of my invention is to provide an ‘improved range of the type above described, in which the photoelectric cell is mounted on a mov ing ill target. , ' r ‘ .. Another purpose is the provision of improved means for connecting the photoelectric cell on the target with an ampli?er normally ?xed in relation to the housing in ‘which the moving target portions are housed. Another purpose is the provision of improved means for counting the shots ?red or the trigger pulls in order to limit the number of trigger pulls available, in a coin operated .machine, for each coin insertion. . Another purpose is the provision of improved scoring means or score recording means. Another purpose is the provision of improved means for controlling the drop portionvof the target whereby,‘ when the photoelectric cell ‘of the target is struck, a drop, which may simulate a bird or animal, falls to indicate a hit. ‘ ‘This application is a division of my applica tion for an electric target ri?e range, ?led on June 15, 1936, Serial No. 85,246. Other purposes will appear from time to time in the course of the speci?cation and claims. I illustrate ‘my invention more or less diagram matically in the accompanying drawings Where m: 35 ‘ Figure 1 is a general wiring diagram with some of the operating parts included; ' Figure 2 is a perspective view of the device as a whole; . r ‘ , ' Figure 3 is a partial interior view of the target 210 structure, looking from the rear; Figure 4 is a section on the line 4-4 of Fig ure 3; I ‘ Figure 5 is a section on the line 5——5 of Fig ure 4; , , ' 45 t Figure 6 is an illustration of the upper portion of Figure 4 with parts in a di?erent position; and Figure 7 is a view of the score indicating de vice, illustrated asv a partof the wiring diagram conductive connections shown in detail in Figure 1 extendbetween the cabinet and the ?ring stand and ‘the. gun and will be later pointed out in detail. ‘ It ‘will ‘be understood that these various connections are carried in ?exible conduits or cables, one such cable D connecting the cabinet A with the gun stand B, and a second E, con necting ‘the gun ‘stand B and the gun 0. Referring to the operative parts of the device, and‘considering v?rst the cabinet structure, gen erally indicated as at A, Iillustrate an outer hous ing I, details of which‘ do not per se form part of the present invention. It will be understood, however, that either an open space or a trans parent window 2 is employed. To ‘the rear of. ‘ this window is any suitable scenic foreground indicated as 3, an upper portion of which is generally arcuate to conform to the path of the target structures below described. However, it will be understood that the details of the scenery and ‘the supporting structure therefor may be widely varied. » Mounted within‘ the housing on any suitable support 4 I illustrate a target base 5 which may be bolted in position as by the bolts 6. It sup ports any suitable bearing construction or’ sleeve ‘1, in which‘ is rotatably mounted the target carry ing‘ shaft '8. Keyed or otherwise secured to this shaft'il is a worm gear 9 in mesh with ‘a worm l0 which may be associated with or driven by any suitable ‘motor M. It will'be understood‘that when the motor H is connected in conductive circuit with "asource of electric power it serves to rotate the shaft 8 and the parts connected thereto.

Like symbols‘ indicate like parts throughout the speci?cation and ‘drawings. ?ash-of light diagrammatically indicated in Fig 1 Referring ?rst to‘ Figure'2, A generally indi cates the .target housing or cabinet; B indicates the ?ring stand; and C indicates generally the the device, the aperture I8 is generallyhorizon tally ali-ned with thephotoelectric cell 22 where by the user, employing a light projecting gun, can sight through the ‘aperture l8 and hit the 55 gun‘ structure.‘ ‘It will be understood that the 35 Secured to the‘opposi-te end of the shaft 8 is a hub I-2 to which are secured radial arms l3, l4. Pivoted to the outer end of each said arm, as at I5, is a drop structure generally indicated as IS, with‘ which is associated the weight H.

Secured on the outer end of each of the target’ arms ‘l3, I4 is .a target bracket generally indicated as at H] to the upper end of which is mounted an angle support 20 upon 45 ures 1 and? by the dotted arrow lines 23. It will be understood that in the operation of 55 2,131,791 2 the rear end thereof, is an incandescent lamp 53. In circuit with the lamp is a mercury controlled cell 22.

I illustrate only one, in Figure l, but more may be employed if necessary. 56 illustrates a trigger pivoted as at 51 and having an inward extension slotted at its rear end as at 21 and provided with a latch hook 28 at its forward end. A spring 29 tends normally to draw the latch member into latch holding position, as shown. 10 in Figure 4, whereby the drop [6 is normally within the gun. Pivoted to this inward extension is a stem 59 10 which is provided with a knob 62 of insulating. material. held in the upright position in which it is shown in Figure 4. I may also employ with the latch a Positioned above the trigger structure is a lon gitudinally movable'stem 12 with a cone-shaped portion 13 intermediate its ends. Pivoted in the aperture 85 in the bottom of the kick-off member 30 adapted, when the latch is lifted into the position in which it is shown in 15 Figure 6, to give a thrust against the back of the target drop structure at the time that the latch is released. gun barrel 5| is a pivoted shutter 81. The details of the gun mechanism are only _ Downwardly extending through a bearing or centering sleeve 3| in the bracket I9 is any diagrammatically illustrated in Figure 1 since 20 they form no part of the present invention. 20 suitable actuating member or stem 32, which A brief description of the gun mechanism is as is provided with adjustable abutments 33, 34, follows: Each time the trigger 56 is pulled, it actuates the movable stem 12 which in turn, by at its lower end, which may be screw-threaded in relation to it and which receive between them the armatures 35 or 359“ associated with the ‘elec means of the cone-shaped portion 13, momen 25 tromagnets 36 or 38a in any suitable fashion upon a lower portion of the arms l3 or I4. It will be understood that the armature may be slotted as at 31 in order to prevent any binding of the parts when the armature 35 is rotated through its per 30 mitted arc of movement in response to excite ment of the electromagnet 36. The downward movement of the armature may also be limited by any suitable abutment 38. The slotting of the latch 26, as at 21, similarly prevents binding at 35 the upper end of the rod 32. It will be understood, of course, that I may provide a wide variety of means for releasing the drop and for holding it in position until released, but the’ above described structure is 40 practical and operative. Any suitable lens or lenses 55 may be employed to direct a bracket [9 is an upstanding pivotal member 25 to which is pivoted any suitable latch member 26 - The drop members It, once they have been released by action of the electromagnets 36, 36a and rod 32, releasing the catch 26, are returned to initial position by gravity, as the arms l3 45 rotate to position below the axis of rotation of the shaft 8. In order to insure the return of the drops Hi to vertical position, I may also employ 25 tarilyopens the shutter 81. The shutter 81, which normally masks the light 53, thus permits a beam of light to escape from the gun barrel 5|. The trigger pull has an additional function, namely that of closing the gun switch which in— 30 cludes the opposed switch spring contacts I09 and. mm. This result is obtained by the engage ment of the knob 62 with the outer end of the leaf I09, as shown in Figure 1, the knob 62 being 35 of insulating material. Referring now to the general schematic circuit layout, as shown in Figure 1, I illustrate terminal lines a and al. The terminal line a connects to one side of the coil a3 of a transformer generally indicated as T. A switch a2 is shown which may be manually operable to terminate the operation of the entire machine. The line a1 extends to the opposite terminal of the primary coil a3. In par allel across the lines a, a1 is the line a4 in which is the motor H. (15 indicates any suitable switch 45 which may be manually operated whereby, when the switch a2 is closed, the motor can still be a guide or cam member shown in‘Figure 3 and indicated as 200. The lower end may be round 50 ed or beveled as at 20! in order to throw the drop switched on and off at will. I illustrate one secondary coil for the trans means shown in Figure 4 and including the latch 26. In order to include the photoelectric cell 22 in 55 a conductive circuit with parts which do not move with the movable portion of the target,vI provide a hub or sleeve member of non-conduc the gun lamp 53.v From the other terminal the conductive line a8 extends to the opposite ter minal of the gun lamp 53. Interposed in it is the mercury switch 54 which is adapted to prevent a closure of the gun lamp circuit unless the gun member l6 into vertical position, in which posi tion it is again received and held by the locking tive material, generally indicated as 40. ‘Mounted 60 in the outer surface of this hub are three com plete slip rings 4|, 42 and 43, and a pair of seg ments 44, 45, which together make a practically complete ring but are insulated from each other. Opposed to each of these rings, and to the seg 65 ments, is an individual conductive contact ?nger illustrated as ME, 42*‘, 43a and 46. As will be clear from Figure 4, two of these conductive ?ngers are positioned above and two below the . axis of rotation of the shaft 8 and they are 70 mounted for example in blocks 41 of non-con ductive material and are normally stationary. 75 former T, at as, which may for example be of 50 small voltage, 6 volts being satisfactory. From one terminal extends the conductive line a7 to is in substantially horizontal position. I may employ a second secondary coil or coils of the transformer T generally indicated as Z). 60 From one terminal extends the conductive line b1 to 222. Extending from the junction 112 is the line b3 to one terminal 124 of the coin operated switch generally indicated as S. Any suitable means S1 may be employed in response to the in sertion of a coin, or at the time of the insertion of the coin, to- move the switch S into closed position.

As will be clear, for example from Figure 1, a The above described connections form a shunt switch including the elements 0-1 and c2 is-closed connection to actuate'the electromagnet' b". Associated with the electromagnet b‘7 is the by the action of the member b114 and Z2115 when 10 armature I I0‘ pivoted as at II I and provided with the member 1715 is movedout of the'notch I20 a ‘spring hammer II 2. opposed to any suitable in the cam disc II8. This is to say. the switches 10 b“, 1215' and c1, 02, are operated in unison in sounding abutment H3 which may, if desired, response to movement of the cam disc II8. be‘a portion of the‘ cabinet.‘ The armature also When the switch members 01, c2 are closed, the includes an upwardly‘ extending‘portion 'IM to photoelectric ampli?er P receives power from the 15 which is pivoted as at H5 a dog “0' opposed to a secondary coil b of the transformer T and is 15 ratchet wheel II'I which has associated with it a cam disc H8, both being mounted on a shaft H9, the cam being provided with ‘a cam- notch I20 adapted to receive a portion of the contact 1115 20 whereby, when the contact 11-15 is alined with the cam notch I 20, the conductive contact between the switch members b14 and I115 is broken. A spring I2I tends normally to hold the dog II6 down against the ratchet and the spring I22 25 tends‘t‘o- hold the armature as a whole against ‘ the stop I23. It‘ will be observed that eleven teeth are shown on the ratchet “1. When the ‘coin switch S is closed, upon the insertion of a coin, the electro 30 magnet b7 is" energized and the armature is moved‘ counter-clockwise; This causes the dog I I6 toride over one tooth. The next time the circuit is‘br‘oken the spring I22 is effective to move the ratchet wheel the distance of one notch. This moves the notch‘ I20out of engagement with the spring-switch contact Z115 and closes the switch. ‘ ' i The operator, having inserted his coin, next takes aim and pulls the trigger 56. This closes the switch "leaves “I00 and I011a and again closes the circuit through the electromagnet I)" through the shunt circuit above described, and this again moves the armature H4 and the dog II 6 over one notch, and'ag'ain permits the spring I22 to . withdraw the armature} and rotate the ratchet the distance of one tooth. Inasmuch as the notch I20 has already cleared the switch 11115, the switch contacts b14 and 1115 are left closed. " i ‘ Another‘ result of the trigger pull is‘the thud‘ to caused by the impact of‘ the hammer I I2 against the opposed abutment I I3 which simulates‘ or suggests the sound of a shot, and which takes place at each trigger pull. ‘After the tenth trigger pull,‘ the notch I20 is again in line with the off-‘set portion of the switch leaf B15 and permits that‘switch to swing out of contact with the opposed switch 1114. This breaks the shunt connection between the trigger switch I00 and I00a,‘ and the insertion of to another coin is necessary to start thedevice. ' The ampli?er circuit and the circuit for the scoring or score recording device may be de scribed as follows: ' f The photoelectric ampli?er cooperates with the ‘1 photoelectric cells 22 and 22a when one of the photoelectric cells is struck by a ?ash of light ‘ from the gun C as generally indicated, as in Fig ure 1,‘ by the ‘letter P. It will be understood that the‘power for the ampli?er is received from the commercial power circuit including‘ the lines a and a1; which operate the transformer T. ready to function. The connection between the photoelectric cell 22 and 22a and the photoelectric ampli?er P is as follows: Tracing from the contact or terminal 09 is the 20 line 010 to'the ?xed contact 42a in contact with the ring 42. Extending from the ring 42 is the conductive line 011 to the junction 012 where it branches as 013, 014 to the photoelectric cells 22 and 22*‘, respectively. Return lines 015 and e16 25 are provided from the two photoelectric cells which join at the junction 01'7 with the line 018 which extends to the ring 43. 43a is another ?xed contact opposed to'the'ring 43 and‘ from it ex tends the conductive line 019 to the terminal 020 30 on the photoelectric ampli?er. traced through b1, b2, 0, to the switch member 01, the opposed switch member 0?, the line 03, pass 75 ing the intersection point 04 and terminating at - light upon the photoelectric cells 22 or 22% is to excite the photoelectric relay (1 which, when ex—1 cited, closes the moving switch contact 111 against 35 the?xed. contact‘dz. The circuit so controlled may be traced. from the secondary coil bi of the transformer T through the line b1 to the junc tion d3, along ‘the lined4 to the junction d5 along the line d6 to the electromagnet d", and thence along the line 018 to the junction 11*‘, and, by the line d1‘), to the ?xed switch member 012. In other words, a circuit is closed which'excites the elec tromagnet d7 and moves the armature d11 which, when moved, lifts the lever arm d12 and‘ moves 45 the dog 0313 against. the ratchet (Z14 and advances the scoring drumv (115 one step. Thus at each actuation of the electromagnet d\7 and‘ the ‘armae ture (ill, the drum (115 is advanced one unit, each unit being? given an appropriate number, and the total number of advances'of the drum (115 50 equallinglthe total number of hits‘made against _ one or the other of“ the photoelectric cells 22 or 22s. The score indicator‘is visible through the window dl?, in the front of the cabinet shown in 55 Figure 2. . > ' ' ' It will be understood ‘that a spring all7 tends normally to keep the armature in the position in which it is shown in Figure 1. The spring (118 is‘to keep the dog (213 in the position in which it is shown against the stop ‘(£19. The function of the spring (Z25 is to cause the drum (Z15 and its as sociated parts to return to initial position, which movement is normally resisted by the detent d2", held in the position in which it is shown by the 65 spring dill ofgFigure 1. . . The circuit controlled'by the relay d and the switch members d1 and d2 is continued from the switch d1 by the line ‘(122 to the junction L123 and‘ by the line d24 to the junction 08' where it joins b.1u_ From the secondary coil 17 a line may be ' The result of the impingement of a flash of ‘ ‘ . . ~ . ‘ . ' In order to- reset the‘drum (Z15 to initial position I provide the following circuit which branches , from the line 03 at the junction 04 as follows: The line e extends from the junction c4 to the 75 2,131,791 4 electromagnet e1 and-continues by the line e2 to the junction 1123 and through the line 1124 to the junction 08, and line b1° which closes the circuit through the secondary coil b of the transformer T and through the switch elements 01, c2 of the shot limit structure. As long as the switch struc ture c1, 02, that is to say, as long as the switch member 1915 is riding on'the periphery of the cam disc H3 and has not yet dropped into the notch 10 I20, the circuit through the electromagnet e1 is closed. At the tenth shot, when the connection between the switch members 01 and c2 is broken, and the circuit is broken through the electro~ magnet e1, the armature e3 is drawn by the 15 spring 64 into the position in which it is shown in Figure 1, and the latch e5 slides forward away from the abutment e6 and its latch or head por tion c7 rides over the pin e8 on the detent (12° in readiness to release the detent d20 and to per~ 20 mit the spring (125 to rotate the parts back to initial position, any suitable stop means being provided to terminate the retrograde movement of the drum (215 when the symbol 0 is alined with the aperture (Z16, as shown in Figure 2. When the device is again set in movement by closure of the coin operated switch S, the electromagnet e1 is again excited and draws to itself the armature e3. When it does so, it moves with it the detent d2", permitting the spring (125 to move the drum 30 (1“ back to the zero position. By the time the detent has cleared the teeth of the ratchet wheel d“, the hump e9 of the latch e5 moves over the abutment e6, causing the latch e5 to lift and release the detent d2", to the position in which 35 it is shown in Figure 11. As long as the circuit continues closed through the switch members 01, c2, the parts remain in that position. The detent d20 prevents retrograde movement of the ratchet d“, while allowing its forward step by step move 40 ment in response to actuation of the arma ture (Z11. ‘ In order to actuate the drop structure, shown’ for example in Figure 4 and including the drop members 16, I provide the already described elec tromagnets 36 and 36%, only one of which can work at a time, because of the employment of the split ring segments 44 and 45 already de scribed. The connection there formed from the transformer T and its secondary coil 1) may be traced by the line d4, through the junction d5, by the line 9 to the normally ?xed contact Me, the ring 4 l , the line g1, through the electromagnet 36, back by the line g2, to the upper segment 44, the normally ?xed contact 46, and the line 93 to. the junction (29, through the line c110 and switch members d2, (11, back along the line (122, junction (123, the lines d24 and 121° to the secondary coil 1) of the transformer T. Similar lines are shown and similarly indi cated, extending to the electromagnet 36a, in con nection with the ring 45. It will be understood however, that only the top drop can ever be shot at and only one can be shot at at a time and only one of the electromagnets 36, 36a can operate at one time. 7 It will be realized that, whereas I have described and illustrated a practical and operative device, nevertheless many changes may be made in the size, shape, number and disposition of parts with out departing from the spirit of my invention. I 70 therefore wish my description and drawings to be taken as in a broad sense illustrative or dia grammatic, rather than as limiting me to the precise showing. I ' In particular, I wish it to be understood that I am claiming primarily a target range and do not intend to limit myself to the particular circuits employed, since a wide variety of substantially equivalent circuits may be employed, which may differ greatly in general detail and tracing, while obtaining the same, or substantially the same, result. I therefore do not wish to be limited to ll) the speci?c structure and circuits here shown except to the extent in which I positively limit myself in the language of the claims. I also wish it to be understood that the photoelectric’ ampli?er employed may vary widely, and vthat it may be practical to put it in continuous circuit and control the motor circuit by the coin switch structure herein shown. In other words, this involves reversing the position of the ampli?er and motor in the diagram of Figure l, a reversal 20 which would be perfectly clear to any skilled operator in the art. - It will be understood, however, that the am pli?er employed is not a source of power for operating the structure herein shown but is 25 merely a means of controlling or actuating the elements involved in response to the excitement or closure of the photoelectric ampli?er relay as a result of hits recorded against the photoelectric cells. It will be understood, therefore, that a 30 wide variety of changes may be made in the wir ing diagram herein shown without departing from the spirit of my invention and scope of my claims. I claim: ' 1. A marksmanship device'comprising an arm 36 mounted for rotation, a light sensitive cell carried by one end of the arm, a pivoted target plate apertured in register'with and carried by the arm and in front of the light sensitive cell, means responsive to 'energization of the cell for causing 40 the target plate to move into a hit indicating position, including a latch member movable end wise of said arm and adapted normally to hold said target plate in upright position, means for releasing said latch member in response to the 45 energization of the cell, including a solenoid and a mechanical connection between said solenoid and said latch member, hammer means and means for causing the hammer means to strike the target plate following its release by the latch to 50 positively urge the target plate into hit indicat ing position. 2.
