' 12 Claims. (o1. gi -105.2)

This invention relates to a. gun shooting apparatususable for amusement purposes or practicing skill in marksmanship. More particularly the invention has to-do with a novel target mechanism and means for moving the target in an improved manner to create interest and to test the marksmans skill to a maximum degree. Herein, the improved target is to be described in connection with a light ray gun shooting game, wherein a photo-electric cell or light responsive element is associated with the target, although it will be obvious as the disclosure is more fully made that the target and the means that moves same is usable in connection with guns shooting bullets other than a bullet of light,

It is desirable to cause the target to move back and forth and up and down in an indeterminate and unpredictable manner so that a real test of marksmanship will be presented.

Accordingly, the main object of the invention is to provide an improved target apparatus.

Another object is to provide improved means for moving the target in a novel manner.

Still another object is to provide motor driven means to cause the target to move in an indeterminate manner.

Other important objects of the invention will become apparent to those versed in this art as the disclosure is more fully made.

Briefly, in a preferred embodiment these objects are achievable by providing a track along which a carriage is driven back and forth by a reversible electric motor which is turned on when the game is released for play as by means of a coin chute controlled circuit. Mounted'for up and down movement on the carriage as the latter moves to and fro is a support carrying a target including-if desired, a photo-electric cell. The carriage carries another electric motor also turned on when the game is started, the said second motor serving to rotate a cam wheel having high portions of varying lengths and varying length dwells. This cam wheel keeps turning as the carriage moves to and fro and regulates a switch that controls the field for the first motor and by reversing the field in an associated circuit the first motor is reversibly driven. This motor on the carriage also turns another cam wheel that actuates linkage for causing the target and its support to bob up and down. Up and down and to and fro motion of the target is thus provided, both movements being of variable stroke to create a surprising haphazard, unpredictable motion for the target behind a drop or panel, which is positioned in front of the target;

A third electric motor is also provided and started simultaneously with the other two, this third motor serving to rotate a wiper switch arm over a circle of contacts. This wiper arm is normally locked, there being a, friction drive coupling between the arm and motor. However, when the light gun has its trigger switch closed, the lock is unlocked and the wiper arm is freed to be driven by the said third motor over the contacts to make circuits causing the electric lamp inthe gun to flash, all as will later be more fully described. By this means a single flash of light can be fired or a rapid series of them to simulate machine gun action,

Figure 10 is an end elevational view of the unit as shown in Figure 9; and,

Figure 11 is a detail plan'view of a portion of the showing in Figure 9 with the wiper arm shown released.

As shown in Figures 1 and 2 there is a light ray shooting gun having a trigger it and a trigger switch I! which is normally open. The gun includes an electric lamp l8 as a light source. An electric cable I9 connects the gun with a cabinet in which the target and control means therefor is housed.

In the housing 20 are opposite brackets 2| for carrying transverse, parallel, lower and upper track rails 22 and 23 on which a carriage 24 is carried for to and fro sliding movement by means of a pair of flanged rollers 25 on horizontal axes on the lower rail 22, and by means of a single roller 26 on a vertical axis on the upper rail 23, as shown best in Figures 5 and fl. The disposition of these rollers is such that .the carriage is held from jumping ofi the track rails.

Looking from the front, it will be seen in Figure 3 that the right hand bracket 2| includes supports for carrying an electric motor 21 having armatures 27' as shown in the wiring diagram included in Figure 3. This motor has a shaft driving reversible 'worm gearing 2B for turning a horizontal shaft 2'9 and a drive sprocket wheel 33. An endless chain 3| .is trained around said wheel-30 and also around an idler sprocket wheel 32 carried in a bracket f33.supported on the opposite structure 21,211 as cleanlyshown in Figure 3.

To the backside of the .carriage 24 (see Figures :5 and '7.) is suitably secured the frame 34 of another electric motor .35 connected by reduction gearing 36 to :drive a fore and aft extending horizontal shaft .3] journaled in the carriage 24 and bracket 34. A push pull link 38 is pivotally connected at :one .end as at 39 to the bracket 34 and at its other end as at 40 is pivotally connected to one run of the chain 3|, said link 33 being disposed under the-shaft 31 thereby limiting upward movement thereof. When the chain 3| is being driven in one direction or another :by the motor 21 it can .now :be appreciated that the link 38 acts to push or pull the carriage 24 and cause it slidably to roll along the track rails 22 and 23.

The shaft 31 on the front face of the carriage 24 (see Figures 3, 4 and 57) has loose on the shaft, the hub of 'a timer disk 4| which by means of a friction disk 4| is turnable with the shaft 3! when the motor is running. As best seen in Figure 3 this disk 41 .is made of insulation and has high cam portions 42 .on its periphery of varying lengths, between which cam portions are dwell portions. .disk is positioned in a manner to cause these cams and dwells to engage one blade of a double lblade, spring contact switch 43 suitably carried .on the carriage 24 and having opposite wire connections 44 and 45. These wires 44 and '45 as shown in the diagram in Figure 3 are in circuit with a suitable source of energy 46 and a reversing relay coil 41. As shown, the armatures 21":Eor1notor 21 by means of wires 48 and 49 are also ;in circuit with the source of energy 46. In the wire 49 is arranged a field coil 5|) for the armatures 21, said coil being controllable by a reversing switch structure 5| controlled by energizat'ion and deenergization of the reversing relay coil 41. Said coil 41 as can be seen is controlled by the opening and closing of the blade switch 43 in response to action of the cam wheel 4|. Consequently, the carriage driving motor 21 is reversibly operated to drive the carriage first one way and then the other. The period of operation of the motor in one direction or the other is obviously determined by the length of the cams 42 and the length of time the switch 43 is held closed. Thus, the stroke or path of movement of the carriage along the track is variable in either direction of movement. The cam wheel 4| is driven at such speed and is so proportioned thtat the carriage 24 can travel within only certain prescribed limits and can never reach the ends of the tracks 22 and 23 and run off or cause damage to any parts.

Looking to Figure 7 it will be seen that by means of a cap 52 and coil spring 53 the disk wheel 4| through a. disk 4| is frictionally clutched to the front face of another cam wheel 54, having a hub keyed to the shaft 3'! always to turn therewith. The front face of the carriage as shown also in Figure 4, above the wheel 54 has a pivot '55, pivotally carrying a gravity lever 55 having a dog end 51 loosely riding the periphery of said cam wheel 54. This wheel 54 is formed with varying length cam and dwell portions as shown on its periphery. Looking now at the disk 4| it will be seen that the same carries variably spaced .pins 58 disposed normal to the plane of "the disk and extending inwardly in a position to be engaged 'by the end 5'! of the dog 56. Whena high cam portion on wheel 54 holds the dog 56 high enough to permit the end 51 to be positioned in the path of the pins 58 on the disk M, then said disk 4| will have its rotation interrupted, the friction disk 4| coming into play to take up the lost motion. Thus, the reversing movements of the motor 21 in driving the carriage 2-4 are so scrambled .or varied as to make such to and fro movement of the carriage completely haphazard and unpredictable. Of course, when the end 51 drops into a dwell on the disk :54 then it cannot engage a pin 58 and the disk 4| will through the friction coupling 4| turn with the shaft 31 and disk 54. The cam wheel 54 performs another important function which will presently be described in connection with a target on the carriage.

This target herein assumes the form of a submarine '59 and as seenin Figures 3 and '7 includes a lens 60 for directing a ray of light to an interior disposed photo-electric cell :6| carried on the angular extension of a target support 62 positioned for up and down sliding movement .in one end of the carriage 24. The other end of the carriage 24 carries for sliding up and down movement, a complementary bar63 the lower end of which has secured thereto a counterweight .64 for a purpose presently to appear. Looking now to Figure 4 it will be seen that below the cam wheel 54 the front face of the'carriage 24 carries a lever 65 pivoted at 66 and between :its ends carrying a roller 61 to ride the periphery of the .disk 54. The opposite end of the lever '65 is pivotally connected at 68 to an upstanding link :69 in turn pivotally connected at 10 to an intermediate portion of a lever 1|, which has one end articulately connected by a link .12 to the bar 63 and its other end similarly connected by a link 73 to the target supporting bar 62. Thus, the bars 62 and 63 are interconnected by the lever 7| for opposite up and down movements and the weight 64 counterbalances the weight of the target structure 59, 6 Looking from the front it will be understood that the wheels 4| and 54 always turn counterclockwise. The motor 35 is not reversible and always runs in the same direction. It will now be clear that as the cam disk 54 turns the cam portions thereof will push down on the roller 61 to swing the lever 65 and cause the relative up and down movements of the bars 62 and 63 as shown in full and dotted lines in Figure 4. Thus, the target 59 bobs up and down behind a curtain drop or front panel 14 included in the cabinet 29, which drop 14 may be painted to represent the sea; Since the cam portions on the disk 54 are of different lengths, a difierent or variable up and down succession of strokes is imparted to the target. This up and down variable target movement combined with theintermediate to and'fro movement of the target carriage along the track creates an unusually interesting target motion, causing the target to appear and disappear from behind the drop 14 in up and down and sidewise movements. A real test for the marksman thus occurs.

The control for the gun lamp I8 will now be described. In a suitable place in the cabinet 29, orin a stand for the gun I not shown, is positioned the unit shown in Figures 9, and 11, which unit comprises a base carrying a U- bracket 18 on which is a sub-bracket 11 carrying an electric motor 18 for driving reduction gearing 19 for turning a shaft 89 connected by a coupling BI to an extension shaft 82. Said shaft 82 is supported with shaft 89 in the U-bracket 16, the shaft 82 as seen, projecting through and beyond the bracket with its far end turnably carried in an end plate 83 made of insulation and carrying (see also Figure 8) a circl of spaced, electrical contacts 84 wired together on the back side of the plate 83 by a wire 85 from which a lead 86 goes to one side of the lamp I8 in the gun I5 as shown in Figure 1.

A conductor wiper arm 81 is secured to a sleeve 88 turnable in the support 83 and loose on the shaft 82 to turn thereon. Formed as a functionally integral part of the sleeve 88 is a disk 89 having peripheral spaces thereon formed by teeth 99. A solenoid 9| having a spring pressed core 92, is positioned on the support 15 in a manner to enable said core normally to engage radially in a peripheral space on the disk 99 and lock it against turning, when the core 9| is not energized. By means of bolts and spacers 92' another disk wheel 93 is secured in spaced relation to the first disk 89. This disk 93 also has peripheral spacers formed by teeth 94.

Secured to the shaft 82 to turn therewith at all times, and positioned adjacent the disk 93 is a drive collar 95 faced on the side proximate the disk 93 with a friction driver facing or washer 96. The collar 95 will have slight axial movement on the shaft 82. On the shaft between the disk 93 and U-bracket 16 is a loose turning sleeve unit 91 which at one end includes a disk 98 having an axial spacer 99, including a detent pin I99 positionable to engage in the spaces between the teeth 94 on the disk 93' to lock disk 98to the disk 93 to turn therewith and rotate the wiper arm 81 when the disk 89 is freed by the solenoid core 92 as will appear.

The other end ofthe sleeve 91 is provided with an integral, wide spur gear I9I and an integral washer I92. The bracket 16 carries a, support I93 for pivotally carrying, by means of a pin I94 a lever I95, which between its ends carries two spaced, depending pins I96 disposed on opposite sides of the washer I92. The free end of the lever I95 carries a depending pin I91 engaged in the notched end of the spring pressed core I98 of a solenoid I99 carried in a support I I9 mounted on the bracket 16. When the core I98 is inoperative the spring thereof holds the core and lever I95 out as shown in Figure 9, thus sliding the sleeve 91 over to the right to move the disk 99 with its detent I99 into locking engagement with the wheel 93, at the same time pressing the collar 95 and its friction face 96 into driving engagement Withfthe disk 93, thereby causing the parts 91, 88 to turn as a'unit with the wiper arm 81 moving over the contacts 84.

The wide gear II is in constant mesh with a large spur gear III journaled on a shaft II2 mounted in the bracket 16 and a journal support II3 thereon. As the gear III turns it winds a clock spring II4 disposed around the shaft H2 and having its opposite ends connected respectively to the gear and shaft. The gear III carries an axially extending pin I I5 from near its periphery to cooperate with an upstanding stop pin I I 6 on the base 15 as seen in Figure 10. The gear III has a starting position determined by the pins H5 and I I6 and as the gear I II turns to move the pin I I5 away from the pin H9, the spring H4 is wound up to store energy for returning the gear I II to its home or starting position when these parts are reset. When the gear wheel I I I has turned one revolution the pins I I5, I I 6 prevent further rotation of the wiper arm 81 and consequently the latter is held fixed between contacts 84 until reset.

Looking now to the diagram of Figure 1, it will be seen, that a main starting switch II1 is provided in the circuit, the same being initially closed by a conventional coin chute II8 operable by the player in releasing the apparatus for use. A wire I I 9 goes from one side of said main switch I I1 to the solenoid I99 and from the other side of said solenoid, a wire I29 leads to one side of the source of energy 46. From the source 46 a wire I 2I leads to one side of a switch I22 and from the other side of said switch is lead a wire I23 connecting with wire I29 and the source of energy. A wire I24 leads from wire IZI and goes into one side of an amplifier I25. The motor 21 is in wire I2I and by cross wires I26 and I21 the motors 35 and 18 are respectively placed in circuit with the source of energy, as shown. An electromagnetically operable hit counter I28 of any standard type is in circuit with the amplifier through wires I29. By means of wires I39 the amplifier is in circuit with the photo-electric cell 6|. A wire I3I leads from the amplifier I25 to a wire I32 in circuit with the source of energy 45 through wire IZI. The wire I32 connects with one side of a relay operated time clock unit I33 positioned to hold closed the switch I22 for the desired time interval. A wire I34 leads from the other side of the relay I 83 to the other side of starting switch H1. A wire I35 goes from wire I 2Iaround the switch I22 and connects with one side of the solenoid 9I while an out wire I 38 from said solenoid goes to one side of the gun trigger switch I1. A wire I31 leads from the other side of the trigger switch to the wire I29 and source of energy 48. A wire I38 goes from the other side of the lamp I8 to the wire I3I and source of energy- A wire I39 connects between the wiper arm 81 and wire I 24. This completes the detailed description of the parts and the manner of use andmode of operation of the apparatus will next be described.

In starting, it is to be understood all parts are at rest in what may be termed reset positions. When the coin chute H8 is operated it closes switch II1 for an instant to make a circuit i3 1, I33, I32, 25, I29. I99 and H9 to energize the solenoid core I98 and cause it to pull in the lever I from the position shown in Figure 9 to that shown in Figure 11. Thus, with the unit 91, 98 pulled over and freed from the wheel 93, the spring I I4, which was energized, acts instantly to turn the gear wheel III back to its initial startingposition determined by pins I I 5 and'l IS. The unit 91 with disk 98 and gear I 9| merely turns loosely about the shaft 82 during this reset operation.

Closing of the switch I I! by thecoin chute also in the same circuit just described, energized the relay timer unit I33 to set a time clock and also close the master switch |22,'which now remains closed by the time clock unit I33 for a predetermined time interval, even though the coin chute I I8 is drawn to retracted position causing opening of the blade switch III. The circuits shown in Figure 1 are now established, causing all motors 27, 35 and 78 to run, the amplifier I likewise being placed in circuit with the source of energy. With the solenoid 9| deenergized normally, the wheel 90 is held locked and the Wiper arm 81 cannot turn over the contacts 84, said arm 81 when at rest having a normal position between adjacent contacts 84 so that no current is passed, as shown in Figure 1. The friction disk 96 makes it possible so to hold the unit 93, 89, 88, 8! stationary. When the coin chute was retracted and switch I I? opened, the solenoid I09 was deenergized so that the spring therein pushed the lever I05 out as seen in Figure 9 to lock the disk 98, through detent I99 to the disk 93. Thus all these sleeve parts 91, 83 are tied together, but normally, held against turning about the shaft 82 by the lock 92, since the coil 9| is normally deenergized and the spring therein holds the core 92 to locking engagement with the teeth 94 of wheel 89.

Of course, the motor 21 turns since it is now in a closed circuit and through the gearing described drives the endless chain 3I to move, through link 38, the carriage 24 on which is carried the target 59 and variator motor 35, which also runs now all during the game cycle. As this motor turns, the cam wheels 54 and 4| likewise turn. The cam portions on wheel 4| control opening and closing of the blade switch 43 for varying time intervals, said switch 43 controlling the circuit 44, 45, shown in Figure 3 that reverses the field for the brushes 21 of the motor 2?, thereby causing the latter to run reversibly. It follows that the carriage 24 is consequently driven to and fro on the tracks 22 and 23 by the endless chain 3| with varying lengths of travel, but never ofi the ends of the rails 22 and 29 because the cams 42 on the cam wheel 4I are designed to prevent this from happening.

At the same time the motor 35 drives the cam wheel 4|, it also drives from the same shaft 31. the second cam wheel 54 having varying length cam portions to act on the roller or pin 61 and operate the counterbalanced parallel ruler linkage 63, 62 to move the target 59 up and down in strokes of varying length. This cam wheel 54 also raises and lowers the stop dog 56 into and out of the path of the pins 58 on the wheel 4| so that the latter wheel is actually momentarily held or locked against turning for varying intervals determined by the length of the cams on the wheel 54. Thus, reversing action of the motor 21 and to and fro strokes of the carriage 24 are additionally scrambled. Such holding action of the wheel il is made possible because of the friction disk driver 4|, between wheels 54 and 4|. It follows that the target 59 moves back and forth and up and down in an unpredictable, haphazard manner, darting up and down and to and fro relative to the drop panel 74 in front of it.

With the target moving under influence of the motors 21 and :35 and the motor "I8 also running but not turning the wiper arm '81 because of the lock 92, the marksman can now shoulder the gun I5 and aim it at the target lens 69. When the gun trigger I6 is pulled the triggerswitch I! is closed to make a circuit I35, I35, I'ZI, '46,, I37 to energize the solenoid 9|. This moves the core 92 out of engagement with the lock wheel 89 to free the latter, whereupon through driver disk and face 96 and coupling I99 the motor I8 through shaft 82 drives sleeve 88 and the wiper arm 81 over the contacts 84. If the trigger I6 is only closed for an instant then the wiper arm 81 contacts only one contact 84, thus making a . circuit 85, 86, I38 with source of energy 46, returning by wires I39, I24, I23, with switch J22 held closed, back to source 46 to light the lamp I8. If the flash of light from the gun hits the photo-cell lens GIL'then the amplifier I25 causes the .hit counter I28 to function. Of course, since the coupling detent I09 is locked to the wheel 93 that turned one step with the wiper arm 81, it follows that the gear |0| turned the gear MI in a direction away from the stop 'I I 6,'the spring I I4 being wound in the process.

Should the trigger switch I! be held closed. then the circuits established keep the wiper 8I turning rapidly over the contacts 84 and the flashes of light from the gun are in rapid succession, like a machine gun, as the wiper 81 runs on and off successive contacts 84. All the while this happens the gear I'II keeps turning away from its home position until it has completed one turn, whereupon the pin II5 abuts the stop I I 6 and the turning parts 91, 88 are locked even though the motor I8 should still be running. The friction 96 takes up the lost 'motion in such instance. When the game cycle is out off by the timer unit -I33, then switch I22 opens and all three motors stop. When the next game is played the coin chute II8 acts to close switch Ill and reset the one revolution control wheel I I by means of the spring I I4 as has been described. This completes the description.

It can now be seen that an improved target apparatus has been provided which achieves the objects heretofore recited.
