This invention relates to amusement apparatus, and particularly to a coin operated mechanical marksmanship device or shooting gallery.
Among the important objects of the invention are the provision of novel moving target means, mechanism for moving movable target elements and operable by a manual control released by deposit of a coin in the machine, together with .novel indicating mechanism for indicating the marksmans score.
Additional and more specific objects are the provision of a shooting gallery in the form of a housing member, having a plurality of target openings and target members periodically movable behind the openings and adapted to be struck by missiles from a mechanical gun in such manner that the said target members may be moved to actuate a score indicating mechanism.
Yet another object of the invention is the provision of a target structure comprising a series of vertically extensive wells having target apertures through the sides thereof, and each having a ball target member reciprocably movable therein into and out of sight before said openings, and cam means for reciprocating said ball members in their respective wells, together with clockwork mechanism for operating said cam members.
Still another object is the provision in a mechanism of the class described, of a clockwork driving mechanism energized by a manually set spring means, and operable to drive said cam members and reciprocate the ball target members.
Further novel features of construction and operation of the device disclosed herein will appear as the following detailed description proceeds in view of the drawings, in which:

The present invention utilizes a mechanical gun It such as shown in Fig. 1, this gun being desirably of the type shown in my U. S. Patent 1,551,858. This type of gun, in accordance with the detailed mechanical description in said patent, is released for operation by deposit of a coin in a slot 52 in the gun and disposed exteriorly of the main housing M, as shown in Fig. 1 herein, the stock and trigger portions of the gun here used also being disposed exteriorly of the housing for manipulation by the user.
It is to be observed that the deposit of a proper coin or token in the slot I2 of the gun releases for movement a latch lever l5 (Fig. 4) which corresponds to the lever 82 shown in Fig. 2 of my aforesaid patent, and in the present novel device this latch lever I6 is pivotally attached to a link it, which in turn is pivoted to an oper ating arm 26 on a driven control shaft 22 (Fig. 2) which is rotatably supported in bracket journals 24 and 25 attached to the inner wall portions of the housing M.
isposed eXteriorly of the housing I4 is a manual operating lever 26 having a short sleeve shaft 28 extending within the housing for pivotal support by the bracket 25 with the central sleeve or bore portion thereof embracing an end 29 of the control shaft 22, such that the lever 25 may be pivoted co-axially with the shaft 22 and independently thereof.
Driving connection is established between the inner sleeve portion of the control lever 25 and the control shaft 22 by the mechanism shown in Fig. 3, in which the innermost extremity of the sleeve 28 of the lever 26 is provided with a lever arm having at its eccentric end portion a pin 32 to which is secured a spring 36. The spring 36 is attached at its opposite extremity to a pin 35 extending from the eccentric end portion of a driven crank arm 38 secured to the control shaft 22 for rotation therewith. A spring 35 is secured to the pin 35 and has its opposite end anchored as at iii to the bracket 25.
It will be observed that the spring 3 1 is, in the embodiment shown, of the extension type and is appreciably stronger than the spring 36, for reasons which will appear in conjunction with the detailed description of the operation of the device.
Disposed interiorly of the housing It and below the inclined panel i5 therein, is a motor means in the form of a clockwork mechanism 40 (Figs. 2 and 4) having a main setting shaft 42 extending exteriorly of an end plate structure 4|, and terminating in a segmental ratchet plate 44 rotatable therewith. Disposed on the supporting plate 4| of the motor adjacent the ratchet teeth of the ratchet plate is a spring-urged pawl 46, engageable with the teeth of the ratchet plate to prevent retroactive movement of the latter until the receded end portions 45 flanking the ratchet teeth on the plate move past the pawl in either direction. Thus the ratchet plate 44 cannot be moved from the position shown in Fig. 4 to a position half way toward the opposite end and then return to its initial position, the stroke must carry the ratchet plate completely past the pawl in both directions.
As seen in Fig. 5, the main drive or winding shaft 42 of the clockwork 40 is operatively clutched to a main driving gear 43 by means of a ratchet gear 48 rotatable with the shaft 42, and rotatable freely of the large gear 43 in an anticlockwise direction, but effecting rotation of the gear 43 in a clockwise direction by engagement with a plurality of dogs or pawls 50 pivotally mounted on the gear 43 and urged by a spring means 49 into engagement with the ratchet gear 48.
The energizing means for the motor 40 com prises, in the embodiment shown, a large extension spring 52 attached at one extremity to the ratchet member 44 by means of a pin 53 extended therefrom, and at its other extremity 54 to the control shaft 22 which serves to anchor the spring. Secured to the control shaft 22 for rotation therewith is a setting lever 56 having its eccentric end portion pivotally connected to a setting arm 58 by means of a pin 51 in the eccentric end portion of the lever, and extend ing into an elongated slot 59 in the arm 58. The opposite extremity of the arm 58 is pivotally engaged with the pin 53 on the ratchet plate 44. Thus the anti-clockwise rotation of the control shaft 22 is transmitted through the arm 56 to the ratchet plate 44 (see Figs. 2 and 4).
The target structure comprises a vertically extending target wall or panel 60 (Figs. 1 and 4) having therein a plurality of target apertures 62. Behind each of these apertures is a well or chamber 64 provided by a casting having a back wall 66, and a plurality of vertical partition walls 68 (see Figs. 6 and 7 and each well having a pair of inwardly extending wings I disposed at the rearward marginal extremities of the partitions and substantially at the midpoint of the same, and which are effective to prevent the movement of a target ball I2 out of the Well except through the open region II above these wings.
The casting is provided with an inclined floor portion 61 over which one of the balls I2 may descend from the rearward region of the casing, adjacent the rear wall 66 thereof, downward through the large lower opening I3 below the wings I0, back into the bottom of the well 64.
' This construction provides for a possible circuitous movement of a ball I2 from a position at the top of the wells 64, over the wings I0 and downward below the wings I0, over the inclined floor 61 and back into the well.
Means for periodically elevating the ball I2 from the bottom floor 61 of the well to the top thereof and before the target opening 62, include in each well an elevating cam I4 (Figs. 2. 4, 6, and 7) supported on a cam shaft I6 journaled, as at I5, in a lower portion of the well casting. Each of the cams I4 extend upwardly within a corresponding well, through a bottom cam slot I8, these slots including a pair of oppositely disposed upstanding side flanges I9 which serve to guide the movement of the cams along a uniform path, and also serve to form one wall for the missile return troughs 80, the other wall 9| of which is provided. by the adjoining well partition 58 of the casting, the forward lowermost extremities of each of these return troughs 80 having an opening 62 communicating with the inclined top return panel or floor I whereby a pellet or missile 83, which has entered the well through the target opening 62, may fall into one of the troughs B0 and pass through the lower openings 82 to descend over the floor I5 toward the gun Ill and into a reloading opening II therein.
The cam shaft I6 is drivingly connected with motor 40 by means of a large gear 86 and a drive chain 81 thereon, and passing over the motor driving gear 88. It may be observed that the speed of the motor 40 may be regulated by any suitable means such as the escapement mechanism 39, so that the cams I4 will pass into and out of the wells 64 at a uniform and preferably leisurely rate, whereby the balls I2 will be engaged by the riding edge of the cam when the same rotates in an anti-clockwise direction, as in Fig. '7 for example, to cause the balls to rise and fall before the target openings 62, it being observed that the inward or idling cam edge is provided with a receding arcuate recess I4 against which the ball I2 may ride while in lowered position.
Score indicating mechanism is provided in the form of a rotatable drum 90 having indicating characters about the periphery thereof, and supported for rotation between bracket means 92 extended from the well casting, so that the indicating numbers or characters may pass before a sight opening 93 in the upper region of the target panel. Rotatable with the shaft 9| of the target 90 is a driven ratchet 94 (Figs. 4, 6, and 8), with which is engageable a stopping dog 96 pivoted, as at 95, on the upper part of the well casting and engageable also with a driving pawl 91 on the upper extremity of a stepping arm 96 pivotally supported on a common shaft 99 which, in turn, is pivotable by any one of a plurality of paddle arms I00 attached to the shaft 99 at their collar portions IOI, and having at their lower extremities a flared portion or ball paddle I02 extending into each of the wells 64 at the lower regions thereof, and engageable by one of the balls I2 in its descent from raised position toward the inclined floor of the well, in such manner that the arm I00 will be pivoted, and consequently the common shaft 99 likewise pivoted, this motion being transmitted to the stepping arm 98 to rotate the drum 90 through the pawl 91 and ratchet 94.
The drum 90 is provided with a coil spring I04 anchored to its shaft 9| and to the drum, so that the spring may be coiled or energized by the stepping movement of the drum, the looking or stopping pawl 96 being effective to prevent retrograde movement of the drum under the tension of spring I04.
In order to release the drum 90 from an indicating position to a normal and non-indicating position after a score has been set up, the latching dog 96 may be pivoted out of latching position (in an anti-clockwise direction) by the backward movement of a slide bar I06 (Figs. 4, 6,
and 8) slidably supported by pin and slot engagement with a bracket I01 on the top of the well housing casting, the slide bar Hi6 having an offset extension I08 which bears against the dog 96 to move the same out of latching position, and the bar having its outermost extremity pivotally connected. as at I09, to the upper end portion of a reset lever H0 pivotally mounted, as at Ill, on the common shaft 99 and having its lowermost end pivotally attached to a reset arm H2.
The arm H2 is pivotally connected at its forward end portions to the releasing lever arm 2! on the control shaft 22, and is movable toward the right by the latter to pivot the reset lever H9 and thus slide the bar :36 inwardly to move the dog 96 out of latching relation with the ratchet gear 94 on the drum, thus permitting the return of the latter to its initial position under urgence of spring N34.
The detailed operation of the device is such that by deposit of a proper coin in the slot IQ of the gun l0, mechanism in the latter will be actuated, in accordance with the disclosures of my aforesaid patent, to release the latching lever I6 of the gun for free movement and also release the missile projecting mechanism of the gun for operation by the trigger in the usual manner.
Having deposited a coin as aforesaid, the user of the apparatus may depress the lever 26, transmitting pivotal motion to the control shaft 22 through the spring link system 34-38, whereupon the energizing arm 58 will move toward the right, as seen in Fig. 4, and pivot the segmental ratchet plate 44 against the tension of the main spring 52. As a result, the winding shaft 42 of the motor 49 will be rotated at corresponding distance free of the driving gear 43, until the 58 reaches the limit of its stroke, whereupon the pawls 50 will lock the gear 43 with the shaft 42 and the tension spring 52 will energize the motor mechanism through the gear 43, thus rotating the motor gear 88 and transmitting rotative movement to the cam shaft 16 through the driving chain 81 and. driven gear 86.
Meanwhile, the pivotal movement of the control shaft 22 by operation of the lever 26 will also have urged the reset arm H2 toward the right, and this motion will be transmitted to the indicating mechanism to move the locking pawl 86 out of locking engagement with the ratchet gear 94 through the medium of the linkage Ill], le and slide bar E06, thus effecting a return of the drum 90 to its initial position under urgence of its coil spring Hi4 and clearing the machine of any previous score.
Thereafter the operator may depress the trigger of the gun I D and project one of the pellets or missiles 83 toward the target apertures 62 and one of the target balls l2 positioned therebehind, by movement of the cams 14, it being understood that as these cams rotate in an anticlockwise direction, as seen in Figs. 4 and 7. each of the several balls '12 in their respective wells 64 rides along the rising cam edge M upwardly into position before its corresponding target opening 52, and as soon as the tail of the cam passes from under the ball the latter will fall downward and idle along the edge 14' of its corresponding cam 74, until the rising cam edge again moves beneath the ball for a repetition of the elevating movement.
Should the marksman succeed in directing one of the pellets 83 through an opening 62 behind which at that moment is positioned a target ball 12, the impact will unseat the ball l2 and cause it to fall backwardly through the upper opening ll above the wings if! at the back of the well, and the ball will thence fall down onto a paddle E62 and pivot its arm ltil and the common shaft 99 so as to pivot the stepping arm 98, which in turn will cause the stepping pawl 91 thereon to engage a tooth of the stepping ratchet 94 on. drum 9i and rotate the drum a distance corresponding to one of the indicating numbers or characters which will be positioned before the sight opening the target panel.
The struck ball '52, having operated the stepping mechanism by impact with the paddle I02, will thereafter descend over the inclined bottom portion of its corresponding well and into the latter through the lower opening l3 below the Wings 70, where the ball will again be engaged by the rising cam for subsequent positioning before its target opening 62. The pellet 83 which succeeded in unseating the ball 12, will meanwhile have descended over the inclined floor trough 88 on the floor of that particular ball well and issue through the lower pellet return opening 82 in the front of the target panel, to descend over the inclined floor l5 and back into the reloading opening ll of the gun.
Having taken number of shots determined by mechanism associated with the gun ill. or otherwise abandoning the operation of the machine, the score, if any, which the operator has set up will remain in reading position until the machine is again. released for operation by deposit of another coin. whereupon the foregoing cycle of operation may be repeated. It will be observed. also, that the mechanism is in effect deenergized by the return of the spring 52 to its initial condition, and suitable means may be provided for preventing a repeated operation of the lever 23 until another coin is deposited in the gun to release the link l? for further free movement. Or. if desired, any well known. form of coin control device may be provided with mechanical connection to link It and the driving mechanism associated therewith, for controlling the release of the machine by deposit of a coin.
The foregoing particularly described apparatus is intended to be illustrative of the invention and as one of the preferred embodiments thereof, and it will be apparent that the particular structure disclosed may be modified in various ways without departing from the spirit of theinventicn, and the foregoing recitations are therefore not intended as limitations but are to be construed broadly within the scope of the appended claims.
