United States Patent F BOW PULL INDICATING MACHINE Sebastian J. Garigal, Dunkirk, N. Y.

Application June 14, 1955, Serial No. 515,356

9 Claims. (Cl. 73-381) This invention generally relates to a skill and amusement device and more specifically provide a coin controlled machine for indicating the force' and movement of a bowstring attached to a resilient bow having known qualities.

An object of the present invention is to provide a bow pull indicating machine having an indicating dial thereon which will directly register the movement'of the bowstring as a quantity of force and successively ring a bell as the force exerted registers predetermined amounts.

A further object of the present invention is to provide a bow pull indicating machine mounted upon a pedestal together with means for maintaining the bow pull machine in various adjusted positions so that the simulated bow and arrow may be adjusted for various sized people.

Yet another object of the present invention is to provide a machine in accordance with the preceding object in which the simulated arrow is connected to an air piston and cylinder arrangement for cushioning the movement thereof when the bowstring is released and the piston is further connected to means for converting the reciprocal movement thereof to rotary movement of a dial hand together with means for returning the dial hand and, the mounting shaft therefor to an index or normal position.

Other objects of the present invention reside in its simplicity of construction, its ease of assembling, adaptation for its specific purpose and its relatively inexpensive manufacturing cost.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a perspective view of the bow pull machine of the present invention;

Figure 2 is a longitudinal, sectional view, taken substantially upon a plane passing along section line 22 of Figure 1 illustrating the internal structural details of the casing;

Figure 3 is a transverse, vertical sectional view taken substantially upon a plane passing along section line 3-3 of Figure 1 illustrating the construction of the rotatable reel pulley and the flexible line attached thereto and its relationship to the gong and bells;

Figure 4 is a front elevational view of the casing of the machine illustrating the dial and the coin receiving slot;

Figure 5 is a detailed sectional view taken substantially upon a plane passing along section line 5-5 of Figure 1 illustrating the details of construction of the supporting base; and

Figure 6 is a longitudinal, vertical sectional view illustrating a modified form of the invention wherein a spring is positioned in the cylinder for returning the mechanism to a normal position.

Referring now specifically to. the drawings, the numeral 2,763,156 Patented Sept. 18, 1956 necting the ends of the plates 22 and 24 is a flexible chain member 28 for limiting the upward pivotal movement of the mounting plate 24 and disposed between the plates 22 and 24 is a spring member 3t) having two upwardly projecting portions 32 wherein the spring 30 is mounted for rotation about a pivot bolt 34 wherein the position of the spring 30 may be altered for supporting the mounting plate 24 in various angular positions in relation to the inclined plate 22 wherein the casing 12 is supported in a desired position in substantially a solid but resilient manner within limits defined by the chain 28 for adapting the bow pull machine 10 for use by persons of varying heights.

The casing or housing 12 generally includes an ovalshaped side wall 36 having a bottom 38 secured to the mounting plate 24 by any suitable means. The casing 12 also includes a back wall or end plate 40 and a front wall or front end plate 42 thereby forming a hollow enclosed casing.

Supported adjacent the bottom of the frant wall 42 is a hollow box member 44 having a pair of generally U shaped rings 46 integrally formed therewith in vertically spaced relation on the outer surface thereof for receiving an elongated resilient bow member 48 wherein the bow member is generally curved in the form of a bow and provided with free ends 50 to which is attached an elongated bowstring 52. Normally, the bows 48 are of a calibrated strength wherein a certain force is required to move the bowstring 52 which is an indication of the force required to flex the bow 48. Normally, bows are rated according to the force required to deflect the bow for shooting an arrow with the bowstring which is the same construction employed in the present invention.

Mounted on the bowstring 52 is a sleeve member 54 having a bore 56 therethrough receiving the bowstring S2. The inner'edge or the edge of the sleeve 54 facing the bow 48 is concave as designated by the numeral 58 for forming a finger grip for pulling the bowstring 52. An elongated arrow rod 60 is screw threaded-into the sleeve 54 and provided with a lock nut 62 for locking the sleeve 54'to the elongated arrow rod .60 which simulates an arrow utilized in actual use of a bow and arrow.

The arrow rod 60 extends through the front wall 42 of casing 12 and terminates at its inner end in a piston 64 which is slidably received in a closed end cylinder 66. The cylinder 66 is mounted on suitable supporting brackets 68 attached to the upper surface of the bottom38 of the casing 12. The cylinder 66 is provided with a small opening '70 adjacent the front Wall 42 of the casing 12 and also with a small opening 72 in the end wall of the cylinder 66 wherein air may enter and exit through the respective openings 70 and 72 during movement of the piston 64 in the cylinder 66. Due to the relatively small size of the openings 70 and 72, the air flowing through these openings will be controlled wherein the air will form a cushion for movement of the piston 64. This is especially important when the bowstring 52'has been moved outwardly and the bow 48 has been flexed and the piston 64 moved towards the front wall 42 of the casing 12. When the bowstring 52 is then released, the normal tendency would be forthe piston 64 to move rapidly towards the closed end of the cylinder 66. However, in view of the throttling nature of the opening 72, the air trapped within the cylinder 66 will act as a cushion for movement of the piston 64. The piston 64 is provided with an eye member 74 on the outer end thereof to which is attached an elongated flexible line 76 which passes out through the closed end of the cylinder 66 and is extended over a small guide pulley 78 mounted on the bracket 80 extending from the cylinder 66.

The flexible line 76 then encircles an enlarged pulley 82 having a generally V-shaped groove 84 in the periphery thereof and the pulley 82 is mounted on an elongated shaft 86 rotatably mounted within the casing 12 and extending longitudinally thereof. The rear end of the shaft 86 is mounted on a bearing 88 and the pulley 82 is secured thereto by a setscrew 90. The other end of the shaft 86 extends through the front wall 42 and is journaled therein and supports an indicating hand or needle 92 that is positioned in a dial housing 94 that is provided with a transparent or glass face 96 having numerical indicia 98 thereon wherein the hand 92 or needle indicates a certain numerical value by pointing at the indicia 98 upon rotation of the shaft 86.

An axial coil spring 100 is mounted on the shaft 86 in surrounding relation thereto and one end thereof is secured to the shaft 86 by the use of a flange collar 102 and a setscrew 104 and the other end is attached to a portion of the casing 12 by an offset end 106 on the spring 100. When the shaft 86 is rotated, the axial coil spring 100 will be tensioned wherein the spring 100 will tend to move the shaft and the needle or hand 92 back to its normal position which actually is an index position.

The operation of the pulley 82 is effected by movement of the piston 64 which is caused by movement of the bowstring 52. Movement of the flexible line 76 rotates the pulley 82 thereby rotating the shaft 86 and the hand or needle 92 for indicating the force exerted on the bowstring 52.

A coin receiving slot 108 projects upwardly from the casing 12 for receiving coins wherein a suitable release mechanism will permit operation of the device. The particular coin mechanism forms no specific part of the present invention but serves to permit collection of revenue from the device.

Mounted on the rear peripheral edge of the pulley 82 is a plurality of projecting prongs 110 which are peripherally spaced and move with the pulley 82. Positioned below and to one side of the pulley 82 is a generally semi-spherical bell 112 mounted on a bracket 114 together with a pivotal gong or hammer 116 having a projection 118 for contacting the bell 112 for ringing the same.

The gong or hammer 116 is pivotally mounted on a pivot pin 120 wherein gravity will urge the projection 118 into contact with the bell 112. The free end of the gong or hammer 116 is disposed in the path of movement of the prongs 110 wherein the prongs 110 will engage and lift the free end of the hammer 116 after which the prongs 110 will release the hammer 116 for falling against the bell 112. This permits ringing of the bell 112 to indicate to the persons employing the device that the needle 92 has been moved a certain amount.

It will be noted that four prongs 110 are provided and the numerical indicia includes the numbers 40, 60, 80 and100. These numbers are the standard strengths of bows employed in archery and when the needle 92 passes each of the indicia 98, the bell 112 will be sounded thereby signaling the position of the needle 92.

In operation, the person employing the device inserts a coin after which the finger grip 58 is grasped and moved rearwardly in the same manner as a bow and arrow is employed wherein the arrow rod 60 will be moved outwardly of the casing 12 and the piston 64 retracted in the cylinder 66. The flexible line 76 will then cause rotation of the pulley 82 and the shaft 86 thereby rotating the needle 92 and causing the prongs 110 to contact the hammer 116 for ringing the bell 112 Wlwfl fil Pfid passes the successive indicia wherein successive ringing of the bell will occur. The axial spring will return the entire mechanism to its normal position and the resiliency of the bow 48 will also force the piston 64 and the rod 60 to its normal position.

In the event a heavy bow is not utilized, the construction of Figure 6 may be utilized wherein a cylinder slidably receives a piston 132 mounted on a piston rod 134 which forms an arrow rod and is moved by the usual bowstring. Disposed between the piston 132 and one end of the cylinder 130 is a compression spring 136 which is calibrated so that the force necessary to compress the spring 136 a certain amount Will be equal to the force necessary to flex the how 48 a certain amount wherein the force exerted will be registered by the dial hand or needle 92.

The bow pulling machine of the present invention provides a device for amusement and skill and also develops the muscles necessary for how pulling wherein the bell 112 indicates the force exerted.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
