United States Patent O SLINGSHOT Soren Pedersen, Riverton, Wyo.

Application March 21, 1956, Serial No. 572,847

1 Claim. (Cl. 124-20) The present invention relates to a slingshot for shooting arrows, balls and other projectiles.

The invention broadly aims to provide a slingshot of sturdy design which is very accurate.

An object of the invention is to provide a slingshot having rubbers which may be easily replaced.

An additional object is to improve the construction of the main outer frame, and to provide an additional pivoted frame which is pivotally mounted on the main outer frame.

Other objects will appear hereinafter throughout the specification.

In the drawings:

Figure 1 is a perspective view of the Slingshot with parts shown in dotted lines and partly broken away;

Figure 2 is a horizontal section taken on the line 2-2 of Figure l;

Figure 3 is a vertical section, partly broken away, taken on the line 3--3 of Figure 1;

Figure 4 is an enlarged section similar to that shown at the left of Figure 2; and

Figure 5 is a front elevation of the sight.

Referring to the drawings, the numeral indicates the main outer frame, and 12 indicates the pivoted inner frame. The main outer frame is rigidly iixed, by welding or other means, to the inner handle or support 14. Rotatably mounted on the inner handle is the outer handle 16 that is provided with ferrules 18. Mounted on the top of the upper ferrule and the lower end of the lower ferrule are thin pieces of sheet metal 20 having apertures through which the inner handle 14 extends.

The outer handle is held in rotatable position by the cotter pin 22, and from upward movement by the anges 24 of the main outer frame. The sling member 26 may be held to the rubbers 28 by any suitable means, such as rivets or staples 30, shown in Figure 1. The opposite ends of the rubbers are tightly held in position on the pivoted inner frame by the spring fasteners 32. Each of these is provided with a depressed or hollowed out portion 34 for the reception of the rubber end and an additional recess 36 is provided into which may be inserted a screw driver or other instrument for the purpose of spreading the spring fasteners for the insertion and removal of the rubber ends.

Each spring fastener is mounted, preferably at its lower end, on the pivoted inner frame by rivets 38. The frame 10 provides trunnions 40, whose upper ends have apertures 42, as seen in Figures 2 and 4, for the reception of a headed rivet 44. Each rivet extends through the aperture of a washer 46 and through the mid-vertical portion of the pivoted inner frame 12, the rivet head being shown at 48, in Figures 2 and 4.

The upper ends of the pivoted inner frame are provided with bent portions 50, only one of which is shown in Figure l. Each bent portion is provided with a pair of apertures, one of which is for the reception of a rivet 52, and the other for the reception of a screw 54. The rivet 52 and screw 54 extend from one bent portion to the other.

Located between the bent portions is the sight 56, provided with a pair of uprights 58 and a iiat portion 60. The sight has an aperture 62 for the rivet 52 and a slot 64 for the screw 54.

It will be appreciated that the sight may be tilted about the pivot 52 when the screw 54 is loosened and may then be held in adjusted position by tightening the screw 54, whereby the sight may be elevated or depressed and held in its adjusted position for diierent ranges or distances. The pivoted inner frame is provided with a Weight or counterbalance 66 that may be held rigidly to the frame by the rivet 68. The purpose of the weight is to maintain the pivoted inner frame in a vertical position.

The rivet 44 because of head 48 is preferably rigid with the pivoted inner frame 12. The rivet however has a friction iit with the main frame 10 that permits manual adjustment of the frame 12 about the axis of the rivets 44.

The above description and drawings disclose a single embodiment of the invention, and specic language has been employed in describing the several figures. It will, nevertheless, be understood that no limitations of the scope of the invention are thereby contemplated, and that various alterations and modifications may be made such as would occur to one skilled in the art to which the invention relates.

I claim:

A Slingshot comprising a primary frame, a handle means connected to said frame, a pivoted secondary frame, means pivoting said secondary frame to said primary frame, attaching means on opposite sides of said secondary frame, contractible spring means held by said attaching means to said secondary frame, a sling member held by said spring means, said secondary frame including a substantially circular part having counterweight means adjacent the lowermost side thereof for biasing said secondary frame to a position in a vertical plane, said secondary frame circular part terminating in a pair of confronting bent portions and an adjustable sight having means for clamping the same between said confronting portions.
