30 Claims. (Cl. 273-1011) The invention 'aims to provide a new and improved shooting gallery in which a flash of light is projected froma gun upon pulling of the trigger, to operate a signal if the aim be accurate. through the instrumentality of a photo-eledtric cell and amplifier.

Another object is to provide novel means for driving a traveling target until the gun trigger has been pulled a predetermined number of times and for then discontinuing operation of the entire gallery. The target driving means and the bulb illuminating means are preferably initially conditioned for operation by means of a r coin switch and the person shooting is permitted to fire a predetermined number of shots for the coin he inserts.

A still further object is the provision of unique means for breaking the bulb circuit a fraction of a second after illumination of the bulb, preventing the user from making attempts to focus the light beam upon the photo-electric cell after a shot has been fired.

A still further object is to makeprovision for moving the target portion at which the gun was aimed to a struck" position if the aim be accu-' rate.

Yet another object is to associate a plurality of electrical units in a novel and advantageous way. to attain the desired ends. With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawings. Fig. 1 is a perspective View showing the traveling target, its driving means and its supporting base. The motor is shown mounted upon this base and while various other electrical units used in carrying out the invention may also be mounted upon said base, they have been omitted from Fig. l for clearness.

Fig. 2 is a perspective view showing the various electrical elements mounted upon the target base,

this view being shown from a point opposite that from which Fig. 1 is viewed. I

Fig. 3 is a. vertical transverse sectional view through the upper portion of the traveling target showing one of the movably mounted target dropportions, the photo-electric cell associated therewith, and the means for effecting movement of said target drop portion to a. struck" position if the aim of thegun be so accurate as to cause thelight flash to strike thephoto-electric cell. a

Fig. 4 is a diagrainshowing the gun, the target,

the various electrical units and the preferred wiring.

The gallery includes a gun 45 having an electric light bulb 46 and a lens 41 for projecting a beam of light toward a target. In the present disclosure, this target is of, the traveling type and is provided with a plurality oftarget drop portions 8 which may simulate ducks, said target drop portions being pivoted at 49 upon bases which are secured to an endless belt 5!. Belt 5! is trained around pulleys 52 and 53 whose shafts 54 and 55 are suitable mounted upon a base 58. An electric motor M is mounted on. the base 55 to drive one of the belt pulleys to effect travel of the target dr'op portions 48 and in the present showing, pulleys 5'! and 58, a belt 59 and a transmission 60, transmit power from said motor M to the shaft 55. Each target drop portion (8 is formed with an opening BI and mounted on the base fill behind said opening, is a photoelectric cell 62. If the person practicing directs the light flash from the bulb d6 through the opening 6| against the cell 62, the target drop portion 48 associated with said cell, drops, and at the same time an additional signal may be operated,

all of which willbe hereinafter fully explained.

Each base 53 carries contacts 63 for its cell 62 and said contacts are co-operable with fixed contact rails Ed and with other means hereinafter drop electro-magnet 69 is provided to swing saidarm 51, causing rail 68 to strike or move the arm 65 and cause 'the target drop portion 48 to drop; The electro-magnet 69 becomes energized only when the flash of light from the bulb 46 is so accurately aimed as to strike the photo-electric cell 62.

In addition to electrical contrlvances so far mentioned, various other electrical units and wiring therefor are employed and'will now be described, and said units may well be mounted on the'base 56.

T denotes a coin slot starting switch located at the shooting post H, for bringing the motor M into play to drive the target, and for preparingthe entire gallery for operation.

. gun 45 and serving primarily to illuminate the l3 refers to a normally open shot limit switch which controls the number of shots which may be fired" upon insertion of one coin in switch 18. This limit switch 13 includes a series of contacts I4, a contact arm 15 co-operable with said contacts, ratchet means I8 for advancing said arm 15- step by step along the contacts I4, an actuating coil C for actuating said ratchet means 15, a detent 11 for holding said ratchet means after each operation thereof, a reset coil C for releasing said detent I1, and a spring 18 for moving the contact arm 15 to a closed starting position when detent I1 is released.

The reference character A, denotes a two pole relay which stands normally open; .B has reference to a three pole relay'which also stands normally open; and C refers to a third and normally closed relay.

' l9 refers to a photo-electric relay and 80 to photo-electric amplifying means. T denotes a transformer, 8! refers to a rectifier and 82 indicates a thud sounder for imitating the report of a gun. 83 denotes a bell and 84 a transformer therefor, both optional.

The various electrical units above described are operatively connected with each other and with two current sourcesfi volt D.-C. and 110 volt A. C., by means of wiring to which the numbers l-to 42 have been applied. All of the wiring will be clear from Fig. 4 and the following explanation of operation, without encumbering the description with an individual statement concerning each wire and such surplusage is therefore omitted. I

When the device is not in. use, all parts stand as seen in Fig. 4, the contact arm of limit switch 13 being then beyond'the series cfcontacts '14. When a person wishes to use the device, the first vact is the placing of coin in coin lll, along wire I to 'i to 8 through actuating coil of relay A along wire 8 to ill through reset coil '3 in shot limit switch, along wire H back to 6 volt source. When coil C is thus energized, it releases detent TI and spring 18 swings contact arm 15 to the closed starting or home position" seen in dotted lines in Fig. 4. The current through the actuating coil of relay A causes the circuits to be completed across contacts which causes current from 110 volt source to fiow from wire IE to l8 through relay contacts to I! to 20 through primary coil or rectifier to 2| to 22 to 23 to 11 to 110 volt source. Wire 24 connects to'wire l9 2il which connects to motor nects to transformer T allowing current to flow through primary winding of transformer T to M allowing current to fiow throughmotor to wire 2l-22-23-ll to 110 volt source. From wire 24 current also flows to wire 25 whichcon 23 to l1 to source.

lead to photo-electric relay I9. This current' current from transformer 'I" at wires 35 and 36.

, takes place. If. the aim is such that the flash of lightfrom bulb 46 contacts photo-electric cell magnet 69 to 42 to I! to source. If bell 83 and transformer 84 are connected, the flow of curdoes not flow, however, until relay I! is closed by photo-electric cell 82 through amplifier 88, etc.

summarily then, the placing of coin in slot switch Ill returned shot limit switch to "home position closed relay A, which put rectifier 8! in service, started motor M which started target moving, and provided a 6 volt A. C. source of It might be well to point out that while the original actuating current for relay A comes from 6 volt source, as soon as rectifier 8| begins to operate and shot limit switch 13 is in home position", relay A is held in closed position by the current from said rectifier 8| until current is interrupted by shot limit switch 13.

The gallery is now ready for the actual shooting operation. When trigger switch '12 on gun 45 is .pulled, current flows from rectifier 8| along wire l2 to I to 4, through trigger switch 12 to 3 through actuating coil C in shot limit switch" to 28 to 28 through actuating coil of relay B to 29 to 30 to l3 to source. Energizing coil C in shot limit switch 13, as previously explained, moves contact arm 15 one position.

Closing of relay B completed 3 circuits thus:

1. From 6 volt A. C. source at transformer T cur- C to 32 across contacts in relay B to 3i to 38 to i3 to source. 3. From 6 volt source. at transformer T along 35 to 38 through actuating coil of thud sounder 82 to 38 across contacts at relay B to 3! to 36 to source.

The first of these three newly completed circuits illuminates the light in gun 45. The second, causes relay C toppen, breaking circuit to the light 45. The fact that relay C is so adjusted as to cause it to operate a fraction of a second slower than relay B allows light to flash for an instant only. The third of these circuits completedcauses the thud to sound. If the aim of the gun has not been accurate no further action 6'! current flows from amplifying unit through cell 62 and rails 64 causing photo-electric relay;

19 to operate. This allows volt A. C. current from contacts at relay A to flow along wire 40 through photo-electric relay l9 to M through rent inthe primary of transformer 84 is simultaneous with that in coil 69, and causes bell 83 to sound when the drop 48 falls.

When the trigger of the gun has been pulled ten times, the contact arm of shot limit switch 13 no longer completes circuit 14 to IE. Breaking this circuit causes relay A to break 110 volt circuit which causes rectifier 8! to cease functioning, motor M to stop and transformer T to cease operation. The gallery then is "dead ready for another sequence of events as just described. It will be observed that the energy for the ac-' tuation of thetarget drop mechanism and of the audible signal 83 comes from an outside source of 110 volt alternating current through a circuit including the lines l5 and II. It will be further observed thatthis circuit is controlled by the relay I8 which is energized fromthe amplifier 80. When I use the term actuate in the speciordinary gun is used, the only connection between the gun and any other part of the mechanism is the light flexible electric' cable which terminates in the gun mechanism. The gun can be laid down, picked up, moved around, manipulated without any reference whatever to any of the working working mechanisms outside of the gun.

The switch and trigger combination in the gun is so set up that a single pull on the trigger causes a single flash of light only to be projected.

Whether the operator holds the trigger or not makes no difference. Nothing but a single flash is projected, as distinguished from a continuous beam, so that if the gun is not aimed at the target at the instant the flash is projected, subsequent' correction of the aim makes no difference. It is I this flash arrangement and this entire portability of the gun which makes my device different from other non-bullet target shooting devices because it enables the user todo exactly what he would.

do if he were firing a bullet.
