1 Claim.

My invention relates to an improvement in electric target rifle ranges of the type in which an aimable member res a flash o f light at a target which may include a photoelectric or light senr, sitive element.

One purpose is the provision of an improved target rie range of the type described in which the target includes a movable base target portion and an apertured target drop portion.

xo Another purpose is the provision of an improved target drop and an improved means for maintaining it normally upright, and for releasing or moving it to depressed position in response to -a hit.

lo Another purpose. is the provision of improved wiring means and control means for such a device.

Another purpose is the provision of an improved score indicating means for such a device.

20 Other purposes will appear from time to time in the course of the specification and claim.

I illustrate my invention more or less diagrammatically in the accompanying drawings wherein:

Figure 1 is a front elevation;

Figure 2 is a -section on an enlarged scale along the line 2 2 of Figure 1;

Figure 3 is a front elevation of the target structure proper;

3() Figure 4 is' a top plan view of the structure shown in Figure 3;

Figure 5- is asection on the line 5 5 of Figure 4;

Figure 6 is a section on the line 6--6 of Fig- 35 ure 4;

Figure 7 is a section on the line '|-'l of Figure 4; i Figure 8 is a section on the line 8--8 of Figure 3; 40 Figure 9 is a section on the lineS-B of Figure 3; and

Figures 10 and ll, taken together, constitute a wiring diagram.

Like parts are indicated by like symbols 4:, throughout the specification and drawings.

Referring to the drawings, I indicates any suitable cabinet having downwardly extending supports 2 and a removable front panel 3. The said front panel hasan upper aperture 4 which may 50 be closed by a pane of glass or equivalent member 5. A lower aperture 6 is closed by a pane of glass 'I which is herein shown as having indicating numbers or signals thereon from zero to ten, as shown in Figure 1, the purpose of which 55 will later appear.

I illustrate any suitable cross pieces or supports 8 Within the cabinet I which may be provided with bearing sleeves 9 which in turn receive bearing pins II) mounted on any suitable panel 1|. I2 beingl means for holding the upper end of said panel whereby the panel is normally in upright position. The panel is provided with an aperture |3, the purpose of which will later appear. The panel II may be of metal and is herein shown as provided With forwardly projecting bosses I4 to which the later described structure is mounted, and also forwardly projecting bearing sleeves l5.

Mounted in said bearing sleeves |5 are any suitable shafts IG which receive pulleys about which passes the belt I8 which may be of the V- belt type. I9 is a drive pulley on one of the said shafts which may be driven by means of a belt from the motor drive pulley 2| associated with the motor 22 herein shown as positioned in the aperture I3. Any suitable gear reduction structure may be interposed between the pulley 2| and the motor. vIt will be understood that when the motor 22 is energized the pulleys Il rotate and cause the belt I8 to move in the direction indicated by the arrow in Figure 3.

23, 24 indicate tracks which include horizontal parallel portions 25 and end portions 26 generally concentric with the axes of rotation of the pulleys Il. These tracks'may be mounted in any suitable fashion as by plates 2l which may be connected together by the cross pieces 28, the inner plates being secured to the bosses |4 as by any suitable screws 29. Mounted for movement along the said tracks are carriages generally indicated as 30, each such carriage having pairs of wheels or rollers 3| engaging the outer track surfaces and pairs of wheels or rollers 32 engaging the inner track surfaces, the distance separating the axes of the outer rollers being slightly greater than that separating the inner, to permit the carriage to move readily around the arcuate portions of the track. I'he carriages 30 may include an upper platform 33, upon which is mounted a photo'electric cell 34 herein shown as provided with a forward chamber 35 which may be closed by the lens 36 the purpose of which is to concentrate light upon the cell 34. The rest of the cell 34 may be painted black or otherwise obscured or, if desired, may be surrounded by a housing, in order that the cell may be protected from any light except that which passes through the lens 36.

Pivoted to the carriage 30 is any suitable target drop member 3l herein indicated as in the form l Thus the carriage is toed by the belt through the of a duck and provided with an aperture 38 which, when the target drop portion is in upright position, is positioned forwardly of and alined with the lens 36. The target drop portion 31 may be pivoted as at 39 andis herein shown as having a downwardly extending lever or levers 40. It is normally held in upright position as by the springs 4I which have inwardly extending drop gripping portions 42, as shown for example in v Figure 4.

` The carriage structure as a whole is moved along the tracks 23, 24 in response to the movement of the-belt I8 by a flexible connection which includes an eye 45. A link structure 46 is pivoted in the eye and includes laterally extending terminal portions 41, 41, which engage side portions of the carriage 30, in a pivotal relationship.

above described flexible connection.

49 indicates a removablescenery back drop and 50 a 'removable foreground apron, the purpose being to simulate an outdoor scene through which the birds or target drop portions may move with 'a f relatively vnatural appearance. It will be clear from Figure li2 that the actuating structure for'` the targets is entirely concealed and only the target drop portions themselves are visible -to the user looking through the glass pane 5,

4It'will be understood that thepurpose of the invention is Vto vprovide a target' range which includes a moving target which can be shot at .with

a gun which shoots what may be described as bullets 'of light. Referring to Figure 11, I illustrate the gun generally indicated as 5i which is provided with a lamp bulb or light source 52, the circuitl forwhich will later be-de'scribed. It is also vprovided with a manually operable trigger 53 which controls a trigger switch 54.' I'he device is initially put in play by inserting alcoin in the coin receiving'element 55 which permits it to be and the target drop portions'31, which move' continuously duringv the periodafter the closure of the coin switch 56,l and continue to move until the operator has taken' his allowed shots. In the `present. structure, the Aoperatorv is permitted tenshots or ten triggerpulls and at the tenth trigger pull the device is put out of operation and the targets cease'to mover f (c) I n order to'limit the number of shots,-I `provide a shot limit yswitch mechanism which is returned to initial position'when the coin switch i '56 is` closed and which is movedv one step at each trigger pull, the tenth trigger -pull serving Vto move theA shot limit switch to inoperative vposition with the result that the operationV of the device ceases.

(di In 'order'fto indicate the score, I provide Iar generallysimilar switch which is moved to zero position when thejcoin switch 56 is closed. At the zero position, the zerolight of the window 1 is illuminated. At every hit recorded against one f of the photo'cell's34`, the nextY ensuing numeral. is illuminated. If the user gets a perfect score, the number 10 is'illuminated at the last Shot and may remain illuminated to indicate the score until the device is prepared for an ensuing user by the insertiony of a coin and the closure ofthe coin switch 56. u

(e) In order to indicate a hit,l I also provide other indicating means. In the rst place, at each hit the target drop portion 31 falls forward and, in the second place, a chime` sound's., A

(f) In vorder to make the device realistic', I also provide a thud sounder whichy may simulate a shot or hit, and which sounds at each trigger pull.

. Considering rst the shot limit switch mechanism,y I illustrate any suitable base or plate 51 upon which is positioned any fixed arcuatecontactr58 whichr is' insulated and which is adapted to be opposed by therotating arm 59. When the device is in initialA position, the arm V59 is in the dotted une position in which it is shown in Figure 11. Its movement is controlled by the ratchet 6l)r which is normally urged in counterclockwise direction of rotation by thev spring 6 il but which is held against such rotation by fthedetent 62 urged into locking position by thefspring 63.

The reset magnet 64, when energized infresponr-:e to the closure of vthe coin switch 56, withdraws the detent 62 and permits the ratchet wheel 60 and the arm 53 to be returned to the initial dotted i line position. Assuming that it is in the initial position, each -triggerpull, or each closure of the f e trigger switch 54 results in the energization of the magnet 6.5 -which in turn moves the armature 66 to the right, referring tothe position of the parts in Figure 11. The dog 61 then moves the ratchet Y wheel 60 -one'step. The springli` returns the armature 66 to the full line positionas soon as the energization of the magnet 65 terminates.

It will be understood that it is energized foronly `an instant. :Thus the result of ten triggerv pulls is ten step by step movements of the arm 59, the' parts being so proportioned that the last movement moves thearm. 59 beyond the end of the segmental contact 58 and thus breaks ythe circuit and puts the machine out of use. l

At the time that the device is being shot,V and at each closure ofthe trigger switch 54,` the electromagnetic coil 10, referring toFigure'8is energized and results ,inf a movement of. the solenoid'armature 1i against any suitable plate or frame portion-12,'r causing a thud to ,sound. A spring, 13 serves to withdraw the-armature 1i when v theenergization .of the coil terminates. Thus, at every trigger pull, a thud sounds, which adds tothe natural effect of the device.`k

, Assuming that the operator so aims his gun 5i as, to direct a-flash of light through the window 5, the aperture 38 and the lens 36, and energizes or strikes the photo cell 34,.the .electromagriet or e solenoid 15 is energized. This causes the armature `16 to move to the right, referring to the e position of the parts in which they are shown in Figure 6.v This in turn rotates the trigger member generally indicated as 11. The upper member or bar 18.then strikes thegdownward extensions 40 of the target drop, frees the target drop from the Asprings 4i and causes it .tofall forward into the dotted line position in which itis `shown in 'Figure 6. Since the member "I1 .is pivoted as at 19, its lower armor portion 80 moves in-the op,- posite direction and rstrikes, abellr or chime 8i, herein shown as mounted on any suitable" bracket, v82on. the track structure. .A spring83,as shown vin `Figure 3, normally holdsvthe structure 11 in thefull line Aposition'in which it is Vshown vin Figure 6. x u

A hit, in addition to causingthe duck to fall and the chime to sound, operates the scoring device. I illustrate, for example, on any suitable base 85 a series of individual iixed contacts 86, 86a, etc., which are insulated from each other. Opposed to them is a moving switch arm 61 pivoted as at 88 and operated by the ratchet wheel l 89 which is normally urged in counterclockwise rotation by the spring 90, the structure being generally similar to the limit switch structure above described. 9| indicates an electromagnet which is energized at each hit. When energized, it moves the armature 92 in such fashion as to cause the dog 93 to move the ratchet wheel 69 one step. Retrograde movement of the ratchet' wheel is prevented by the detent 94 which is held in operative position by the spring Q5 unless and until it is withdrawn by the energization of the reset magnet 96. Both the shot limit mechanism and scoring device above referred to may be enclosed in housings 51a and 65a, respectively, and may be mounted upon the panel The operation of the device may be summarized as follows. When the operator inserts a coin and closes the switch 56, the reset magnets 64 and 96 are energized and both the shot limit switch and the scoring switch are returned to the initial o1' dotted line positions in which they are shown in Figure 11. At the same time, the motor 22 is energized and the targets begin to move.

When the operator aims and pulls the trigger,

and closes the switch 54, the result is an energization of the light 52 and the projection of` a brieiiy timed flash of light from the gun 5|.v 'I'he thud sounder 1| also sounds, simulating a shot or the impact of a' bullet against the target.

The operator tries to hit the photo cell by holding his aim on the lens 36 which he sees through the aperture 38 of the target drop. If he is successiul in hitting the photo cell, he energizes both of the electromagnets 65 and 9|. The energization of 65, which results each time thev trigger switch 54 is closed, merely uses up one shot by moving the arm 59 one step. The energization of the electromagnet 8| extingulshes the light zero and illuminates the light I to the rear of the window aperture 6. In this connection, and asso-- ciated with each of the contacts V|36, 66a, I may employ an incandescent lamp |0|, lllla, etc. -A'

further result of a hit is the forward-fall of the target drop member 3'! which indicates that the bird has been struck and the sounding of the chime 8|.

After the operator has taken ten shots, the arm 59 breaks its contact with the contact 56 and breaks the circuit for the motor 22, thus causing the targets to cease their motion. By a limit switch structure which will later be described, the targets continue to move until the upper target drop is centered midway between the ends of the track, and all further movement then ceases.

The scoring light remains illuminated to indicate the total number of hits and the device is out of operation until the next ensuing operator inserts a coin and closes the switch 56.

It will be understood that I may employ a considerable variety of circuits in obtaining the above result and I do not wish to be limited to any specic circuit. I illustrate, however, a practical and operative circuit which has actually been employed.

In order to provide 'a connection between the cell 34 which is on a moving structure and the necessary amplier and fixed parts, I illustrate a Contact track member 91 which may be mounted on any suitable insulating blocks 96 associated with the cross pieces 28. Opposed to the tracks 91l are contact rollers 99 which may be mounted on springs |00 associated with the carriages or bases 30. They may be mounted on insulating blocks or members |02. The track 91 provides one connection for the cell and the other connection may be obtained as by grounding on the carriage structure.

The indicating lamps |0|, |0|a, etc., may be mounted on a frame |03 which is divided into compartments by walls |04. The frame |03 may be mounted upon the panel, for example, by arms |05.

Referring to the wiring diagram of Figures 10 and 11, a source of outside 110 volt current is indicated at ||5, ||6, although it will be understood that any suitable voltage may be employed and the device may be operated on direct current. However, for convenience, I illustrate it in connection with 110 volt alternating current. A manually controlled switch ||1 may be interposed in one of the power lines whereby the entire circuitl may be broken. Shunted across the main power lines' are the lamps l I6, ||9, which are controlled by the switch ||1. The lamp ||9 is illustrated in Figure 1, as mounted at the bottom of the cabinet I, and is visible through a lens |06. The lamp H8 is preferably mounted above the target structure to illuminate the scenery panels 49, 50 and the target drops 31. A pair of colored lamps |20, |20 may be mounted at either side of the lamp l I6; its purpose being to indicate, when energized, that the device is in operation.

, Electrically connected with the main power lines H5, I|6 is the primary winding |2| oi a power transformer T. A second transformer T' has one side of its primary winding |22 connected to the main power line ||5. The primary winding of the transformer T serves to energize the secondary windings |23, |24, |25 and |26. The transformer T is provided with secondary windings |21, |28 and |29 of which the windings |26 and |29 are electrically connected with the rectifying units |30, |3| which in turn are connected in series by a line |32. The. secondary coil |21 is connected by lines |33, |34 to the plates of a rectifying tube |35 associated with any suitable photoelectric amplifier, indicated by A. The electrical circuit of the amplifier A is merely illustrated as an example, since several well known photoelectric circuits are suitable for the operation of my invention.

For exempliiication, I have illustrated an amplifying tube |36, the grid element of which is connected by a line |31 to the rail 91 which in turn is engaged by the rollers 99 on the spring |00 associated with the target carriage 30. The spring is electrically connected to the anode of the photoelectric cell 34.

In the drawings I have illustrated two target carriages 30, each of which carries a photoelectric cell 34. Since only one target drop is visible at a time, an electrical rail 91 extending parallel with the upper edge of the rails 23, 24 may be employed as illustrated in Figure 5 or, if desired, it may be a continuous rail conforming to the contour of the rails.

Referring back to the diagrams of Figures l0 and 11, the cathode of the photoelectric cell 34 is diagrammatically connected by a line with a ground connection |36. Likewise, the center tap of the secondary winding |21 of the transformer T is grounded as at |39.

'I'he secondary coil |23 of the transformer T supplies current to the filament of the amplifysecondary coil |24 is connected by the lines |42, |43 to the filament of the rectifyingtube |35. The Vsecondary winding |25 of the transformer T connects to a rectier"|44, the purpose 'offwhich will later appear. The end taps'ofsecondary winding |26 are provided with lines |45; |46 ot" which the line extends to the switch arm 81 of the score indicator. The line |46 is connected to one side of the indicating lights |0|, |0|a etc., the'other terminals of'whichare connected by lines |41 leading yto their respective contacts 86, 86a, etc.

Incorporated inthe electrical circuits belowther,`the rre'ctiiying tube |35 and amplifying tube |36 are energized by the secondary windings- |23 and |24. .n

An additional circuit is providedthrough the electromagnet |5| which previously had been established by the limit switch |55, later to be described in detail, which may be traced from the positive terminal of the rectifier |44 through line |56, |51,- electromagnet |5|, linel |58, closed switch |59l associated with electromagnet |52, line |60 leading to the closed switch |6| of electromagnet |5|, thence through lines |62, |63 and' |64 to the negative terminal of the rectifier |44.

Obviously, in the normal operation ofthe device, when'at rest, the electromagnet |5| is energized and its associated switch members |6| and |65 are in the position indicated in full lines` of Figure 10.

Assumingl the userinserts a coin or token into the coin slide and manipulates it in the usual manner, he temporarily closes the coin controlled switch 56, preferably located in a suitable gun cabinet C and closes the following electrical circuit through the electromagnet |50 traceable from the positive terminal of the rectifier |44 through the lines |56, |66, electromagnet|50and line |61 leading to the coin controlled switch 56,

thence through the lines |68, |69, |10, |63, |64 tov the negativeterminal of the rectifier |44. Energization of the electromagnet |50 results; in closure of the associated switch members |1|,

|12 and |13 and opening of the switch membersl |14 and |15, completingthereby the following circuits I First, a circuit through the primary winding |22 of thev transformer T' and simultaneously through thecoloredvlamps |20, |20, from the main power line ||5 through the primary winding |22 and` line |16 to the junction point'|11, and the additional shunt connection |18, lamps |20, |2|-andline |19 leading to said junction point |11, thence through lines |80, closed switch |12 and lines' |82, |83 to the other power line |I6. This results in energization of the vsecondary `windings |21, |28 and-|29 of the'transformer T and consequently of the associated circuits previously described.

An electrical circuit` through the reset magnetsv 64 and96 of the shot limiting means 51 and score g 'ing tube |36 through thelines |40,V |4|. 'I'he indicating device 85, respectively, may now be .traced from the positive terminal of the rectifier |30, which is connected'in series with the rectifier |30, along the lines |84, |85, |86 to the closed switch |13, thence along the -line |81, line |88r and shunt line |89 leadingvto the reset magnets 64' and 96 respectively, thence continues through the lines- |90 land shunt line |9|, the common lines |10, |63, and lines |92, |93 tothe negative 1 terminal of the rectifier |3|.

Inpractice, the negative terminals of both the,

rectifiers |3| .and :|44 as well as the groundy coni nections |38, |39, are grounded 'to the metal frame or panel to eliminate wiring.

' The sh'otlimit switch mechanism'and the score indicating mechanism are thus returned to initial position with the switch members 59 and 8T- i assuming Athe dotted `line position as illustrated inV Figure 11. The score indicating lightv |0| is now illuminated as well as the colored lamps |20, |20 indicating that the device is ready for its cycle of operation.

As soon as the operator releases the manually controlled coin slide 55, it automatically vreturns to inoperative position ina well known manner and opens the switch 56, thusbreaking thecircuit vthrough the electromagnet |50 above described, and its associated switch members re-v turn to the position illustrated in Figure 10. That is to say, the switch members |1|, |12 and :sok

|13are opened and the switch members |14` and |15 are closed.

Energ-ization of the secondary coil |21 of the transformer Tf further results in energizing the amplifier circuits by means of the rectifying tube |35. The potentiometer 203 of the amplifier A in conjunction with the cathode of the power output tube |36 is adjusted to venergize the photoelectric relay |53 when the amplifier circuits are completed and energized by the transformer T', except for momentary interruptions, when the photoelectric cell 34 is energized or actuated when struck by a flash of light from the gun 5I.

The lphotoelectric amplifierv A is connected by line 204 and lines 205 and |43 respectively, with the photoelectric relayk |53, which, whenener gized, closes the switch'members `200, 20| 'and opens the switch 202.

The circuit of the cathode of the poweroutput tube |36 andpotentiometer 203 had previously been closed by a switch. 206 associated with the electromagnet |49 and may partially be traced from the potentiometer 203 through lines 201, 208, switch 206, lines 209, 2|0to-the ground |38 and thence to the grounded center tap |39 of thedescribed in detail, the circuit of the condenser.

2|4 may be traced. from the intersecting point .2|5 inthe line |43 leading to the filament of the rectifying tube |35 through the line2.|6, a resistor 2|1, ,line 2|8, a switch 2 |9, associated with the electromagnet' |49, and a line 220 to the conf denser 2|4, thence through lines 2|3, 2|0 and ground |38 to grounded center'tap |39 of the secondaryy coil |21 of the-transformer T' which in turn is connected by lines |33, |34 to the plates of,y the rectiflllg tube |35,

Closure of the switch 20| of the photoel'ectric relay, |53 closes a circuit through the electromagnet |52, which is traceable from the positive The electromagnet |52; thus energized, closes K the switch members 221, 228 and opens the switch members |59 and 229. The switch member 228 closes a shunt connection in circuit with theeiectromagnet |52 by means of a line 230, which, in eiect shunts out 'the switch member 20| associated with the photoelectric relay |53.

Opening of the switchmember |59 interrupts the circuit through the electromagnet |5| above described and the switch members |6| and |65 move to the dotted line position of Figure 10. I'he switch member |65, now closed, completes a'circuit through the ,motor 22 from the main power line ||5, through the line 23|, a normally closed switch 232, the motor 22, an adjustable resistor 233, and line 234, to the switch |65, thence through the lines 235, 236, and |83 to the other power line I6.

The motor 22, thence commences to rotate the pulleys |1, which in turn lmoves'the belt |8 and the target carriages 30.

The user may now commence to .shoot at the moving targets. As .soon as he pulls the trigger 53 of the gun 5| he closes the switch 54 momentarily, which results in a flash of light to project from thegun barrel, simulating in effect a bullet of light."

The gun switch 54 closes a circuit through the electromagnet |49, winch may be traced as follows: From the positive terminal of the rectifier |30 through the lines |84, |85, 231, the closed switch 14, lines 238, 239, to the electromagnet 49, thence through the lines 240, 24|, throughthe gun switch 54 and lines 242, |69, |10, |63, |92, and |93 to the negative terminal of the rectifier |3|.

'I'he electromagnet |49, thus energized, closes the multiple switch members 243, 244, 245, and

24h, and opens the switch members2|9 and 206.

A'Ihe following electrical circuits are thus completed; closure of the switch member 246 closes' a circuit through-the electromagnets 48, which may be traced from the condenser 2| 4, the energizing circuit of which hasA been previouslyV de scribed, through the lines 2| 3, and 241, leading to the electromagnet |48, thence through the line 248, the switch member 246, and lines 249 and 220 to the condenser 2|4, In other. words, the

energy stored up in the condenser 2|4 actuates the electromagnet |48 when the switch member 246 is closed and the switch member 2|9 isopened.

The electromagnet |48 in turn closes the switch members 250 and 25|, and closes a circuit through the transformer T-2 in the gun cabinet C which may be. traced from. the main power line ||5 through the' lines 23|, 252, 253, to the primary coil 254 of the transformer T-2, thence through the line 255, switch member 25|, lines 256, 251 to the closed switch member |15, associated with the electromagnet |50, and'continues through the lines 258, |8|, 259, the closed switch member 221, and lines 260, 236' and |83, to the other power line ||6. The primary coil 254, of the transformer T-2 in turn energlzes the secondary coil 26|, and closes a circuit through the gun lamp 52, by means of the line 262 leading from the secondary coil to the gun lamp 62 and continues through the lines 263, 242, and 264 to the other ,side of the secondary coil 26|.

Note that the electromagnet |46 is energized yonly momentarily by the above described circuits, .resulting ih illuminating the gun lamp 62 to produce in eiect a iash of light, which may be called a light bullet. 1 Closure Voif the switch vmember 26| associated with the electromagnet |48 closes an electrical 10, thence through the lines 266, the closed switch.

member 243, lines 261, 251, through the closed switch |15, lines 258, 8|, 259, the closed switch member 221, and lines 260, 236, |83, to the vother power line ||6. r In addition the switch member 246, associated with thev electromagnet |49 closes a circuit through the electromagnet 66 of the shot limiting means, which may be traced from the positive terminal of the rectifier |30 through the. lines |84, |85, 231, the closed switch |14, the lines 238, 210, 21|, 212, to the' electromagnet 65, thence through the line 213, lthe closed switch member 245, and lines 214, 215, and |93, to the negative terminal of the rectifier |3|, which is connected in Vseries with the rectier |30.

' Energization of the electromagnet 66 results in advancing the switch arm 59 in relation to the 4contact segment 58 one step.

step. If the operator has been successful in obtaining a hit, that is to say, the flash of light hasf struck the photoelectric cell 34 upon the moving target 30, the additional circuits are completed.

First, energization of the photoelectric cell 34 deenergizes the photoelectric 'relay |53 momentarily. This in turn opens the associated switch members 200, and-20 and closes the switch mem-5 .ber 202. Closure of the switch member 202 closes the circuit through the target drop solenoid 16, which may be traced from the positive terminal of the rectifier |30, through the lines |84, |86,

line 238, 210, 21|, 211, to the magnetic coil 16 of the solenoid, thence through the line 218, the switch member 202, and lines-|10, |63, |92and |93, to the negative terminal of the rectifier |3|. Actuation of the solenoid coil 15 results in the target drop 31 to fall, and further to sound the chime 8|. In addition, theelectromagnet 9| is energized by means of the shunt connection including the lines 219 and 280 which connect to the lines 210 and 218, respectively. Energization of the electromagnet 9| advances the arm 81 of the score indicating unit 85 to the succeeding contact 86a, assuming the arm 81 has been in register with the contact 86 associated with the zero indicating lamp 0|, The score lamp |0|a is thus illuminated, indicating one hit.

At the tenth trigger pull, the arm 69 of the shot limiting means leaves the contact 56. However, the electromagnet |52 remains energized to complete its cycle of operation by the shunt connection 244a connected to the closed switch member 244 of the electromagnet 49, as long as the gun switch 64 remains closed, As soon as the circuit ivo-- members iii!` and 229 close.4 Closurek of the switch member |58 partially closes a circuit .through thel'eiectromagnet VIBI, 'which isc'ompleted whena'rol1er285, carried by each targety carriage, closesfthe limit switch |55..v i
