Int. Cl. F41b 7/00 U.S. Cl. 124-16 Claims ABSTRACT OF THE DISCLOSURE Apparatus comprising a whip shot or slingshot type device in which a shot block is provided with stirrup means for holding it' in an inoperative position and a gun stock and whip frame are provided with trigger release means for releasing the stirrup to permit movement of the shot block and with biasing means and block and tackle means operatively connected to the shot block through sling means so as tocause the shot block to be whipped or released with a quick action force to propel the shot block and to discharge the projectile from the shot block at a great speed. s

The presentinvention relates to a whip shot device which is intended to use buckshot, smaller shot, stones, darts, and the like, that can be hurled at great speeds.

It is an object of the present invention to provide a whip shot device having a block and tackle means to which is attached a strong biasing means with a shot block also attached to the block and tackle means so that when the shot block is released, the spring or biasing means and the block and tackle means will cause the shot block to be hurled forward at great speed and to release a projectile carried by the shot block.

It is yet another object of the present invention to provide a compact and easily manufactured whip shot device with a novel biasing means incorporatedin the frame thereof and with block and tackle means attached to the biasing means and to a shot block so that the shot block isquickly moved forward to release a projectile carried therebywhen the whip shot device is cocked into its operative position. v

Another object of the present invention is to provide a whip shot device having novel cocking means in which the shot block can be moved back to its operative or loaded position by cocking a cocking bar so that the biasing means which supplies the energy necessary to whip or hurl the shot block forward to release a projectile, is shortened to permit extra slack in the sling line that is connected to the block.

Another object of the present invention is to provide a whip shot device in which the cocking bar lever means is returned to its position beneath the stock after the device has been properly cocked. I

Yet another object of the :present invention is to provide a whip shot device having cocking bar lever means that are bought downwardly from the bottom of the stock frame by the shooter grasping the cocking bar lever means, which movement of the cocking bar lever means allows extra slack in a sling line disposed atop the Whip shot'device stock.

Various other objects and advantages of the present invention will be readily apparent from the following description when considered in connection with the ac- 3,509,863 Patented May 5, 1970 companying drawings forming a part thereof, and in which:

tion 22 which closes off the bottom of the hollow central section or bore 20, as best seen in FIG. 5. The bottom section 22 is provided with a front section 24 and a rear section 26 that is hinged together by a hinge member 28. The rear section 26 is further provided with an enlarged, elongated hand grip portion 30, to which is secured by any suitable means a trigger guard 32 and a trigger 34.

Disposed within the central hollow section 20 is a biasing member or spring 36. The spring 36 has its rear end secured to a pin 38, which pin 38 in turn is connected to the rear ends of two spaced parallel extending link members 40. The front ends of the link members 40 are se-' cured by pivot pins 42 to the upstanding legs 44 of a U-shaped member 46. The U-shaped member 46 is'secured by a rivet or other suitable means to the upper surface of the rear portion 26 of the bottom 22 of the stock frame. It will be noted that links 40 extend from a position adjacent the mid portion of the hand grip portion 30 to a position short of the front end of the rear section 26. A triangular shaped guide block 48 is secured to the rear of the top portion 16 adjacent a rear wall 50 which extends between the top 16 and the bottom 22, as;

best seen inFIGS. 3 and 4.

The front end of the spring36 is connected to a rearly disposed double tackle block or pulley 52. Another double block or pulley 54, similar to the pulley 52, ex:

cept that it is disposed in an opposite direction, is secured to an eye bolt 56, secured to a front wall or plate 58', extending between the top 16 and bottom 22 stock frame. 1

An opening or slot 58 is provided in the front end of the top 16 adjacent the front double pulley 54 and a siiigle pulley 60 is suitably secured therein to the top 16.' A shot block member 62 is disposedon top of the top 16 of the frame and is connected to one end, namely therear end, 64 of a sling which may be a twisted wire cable; or rope. The sling 64 is arranged over the pulley 60 and over the

double pulleys

52 and 54, as clearly seen in FIGS. 3 and 4, with its opposite end secured to the rear double pulley of the The shot block 62 comprises a rear horizontally extending Wood block 66, with a slot 68 in the front thereof, in which is disposed the rear end of the sling 64, and further provided with side and rear upstanding walls 70 for holding the projectile thereon. A U-shaped bar or stirrup 72 has its opposite ends embedded in the opposite sides of the block 66 and is used to restrain the shot block in its cocked position, as hereinafter described. The top 16 extends slightly above the side portions 18 as best seen in FIG. 5, and the underside of the block 66 is provided with a slight groove or cut-out section therein, so that the block will be guided as it is whipped forward to hurl or throw the projectile that the block has been loaded with. Of course, other suitable guide means may be used as desired to guide the block as it is whipped forward.

The portion of the frame 14 between the rear wall 50 and the front edge of the gun stock 12 is provided with a compartment or recess 74 therein, in which is disposed the trigger 34 and the shot block releasing mechanism.

Referring to FIG. 6, it will be noted that the trigger 34 is pivoted on a horizontally extending and transversely extending compartment 76, secured to the handle grip portion 30. The lower end of the trigger 34 is provided with a spring 68 which normally urges the lower end of the trigger in a forward position against the horizontal stop bar 80. Disposed in the compartment 76 is an L-shaped retainer member 82, having a lower horizontal leg and pivoted to a transverse pin 84. The upper end of the L-shaped retainer 82 is provided with a spring 84, which normally urges the retainer against a stop bar 86. A vertical release bar 88 is pivoted on a cross pin 90 and a' spring 92 normally urges the lower end of the release arm 88 against a cross bar stop 94. When the device has been cooked and is in an operative position, the stirrup 72 is disposed over the upper end of the release arm 88 and the lower end of the release-arm 88 is in a position shown in, FIG. 6 with the front edge of the horizontal leg of the L-shaped retainer 82 bearing thereagainst. At this time, the spring 78 maintains the upper hammer end 96 of the trigger 34 out of contact with the rear vertical leg of the L-shaped retainer member 82. Preferably metal side plates 98 enclose the sides of the compartment 74 and are secured together by any suitable means.

When it is desired to utilize and operate the whip shot device of the present invention, it is first necessary to load and cook the device. It will be assumed that the shot block has discharged or hurled its load and it is now desired to recock and reload the device for hurling another projectile. Referring to FIG. 4, the position of the spring 36 in this figure is shown in an inoperative position or in a position in which the force of the spring has been utilized to hurl a missile or projectile forward. In order to reload the device, the hand grip 30 is pulled downwardly into the dotted position shown in FIG. 4.

At this time, the link members 40 will be moved dWl1-,

wardly from their concealed position within the frame to the dotted position indicated in FIG. 4. This will cause the pin 38 to which the rear end of the spring is connected to move forward to the position indicated in dotted lines in FIG. 4, so that the spring 36 has its rear end moved forward. This permits the sling member 64 to have slack therein so that the shot block 62, which is in the solid line position shown in FIG. 4, when it has just hurled a missile or projectile, can be slid or moved rearwardly to the dotted line position shown in FIG. 4. When the shot block 62 is moved to the rearward position, the stirrup 72 is then hooked over the release member 88, as best seen in FIG. 6, and the hand grip portion 30 is moved upwardly about the hinge 28 so that the rear section 26 of the bottom 22 acts as a cocking bar lever member at this time, and the link members 40 move rearwardly in the hollow central section 20 in order to stretch or elongate the spring 36 to the firing position shown in FIG. 3,

4 with the force of the spring again energized so as to release the shot block 62 when the trigger 34 is actuated.

In firing the shot block 62, the trigger 34 is moved rearwardly against the force of the spring 78 so that its hammer 96 will cause the upper end of the L-shaped retainer member 82 to be moved forward and to pivot about the pin, 84 so that its horizontal leg will be pivoted clockwise so as to fall below the ower edge of the release bar 88. This will enable the force in the spring 36, transmitted through the block and tackle

members

52 and 54 and the sling 64 to cause the release member 88 to have its upper end tipped forward so that the stirrup 72 slides off of it .and the shot block is pulled or whipped vigorously forwardly so that any short or missle disposed on the shot block will be hurled forward.

Thus, from the foregoing description, it is apparent that the present invention provides a novel whip shot device, in which the cocking is done by moving the cocking lever portion downwardly so that the spring has its rear, end moved forwardly so that the sling or connecting member between the spring and'the shot block is provided with sufficient slack so that the short block can be reset for firing again. I

The present invention further provides a novel and compact arrangement in which the trigger mechanism is simplified and the cocking mechanism is simplified and the transmittal force from the biasing means to the shot block is done in a most eflicient and simple manner.

Inasmuch as various changes may be made in the relative arrangement and location of the parts without departing from the scope of the invention, it is not meant to limit the invention except bythe scope of the appended claims.
