Application March 1, 1954, Serial No. 413,165

2 Claims. (Cl. 124-22) My invention relates to sporting equipment, and more particularly to an improved arrow projecting gun.

An object of my invention is to provide an improved arrow projecting gun having an elastic tubular-shaped sling member.

Another object of my invention is to provide an improved arrow projecting gun wherein the ends of the sling are frictionally secured to a support at the forward end of the gun.

Yet another object of my invention is to provide an arrow projecting gun having means to prevent the closed or loop end of the sling from rising above the end of an arrow when firing.

Still another object of my invention is to provide an improved arrow projecting gun having means to retain an arrow in seated firing position on the gun barrel.

With these and other objects in view, which may be incident to my improvements, the invention consists in the parts and combinations to be hereinafter set forth and claimed, with the understanding that the several necessary elements, comprising my invention, may be varied in construction, proportions and arrangement, without departing from the spirit and scope of the appended claims.

In order to make my invention more clearly understood, I have shown in the accompanying drawings means for carrying the same into practical effect, without limiting the improvements in their useful applications to the particular constructions, which for the purpose of explanation, have been made the subject of illustration.

In the drawings:

Figure 1 is a top plan view of the gun of the present invention showing an arrow in the firing position;

Fig. 2 is a side elevational View of the gun shown in Fig. 1;

Fig. 3 is an enlarged top plan view showing the means used to retain the arrow on the gun barrel;

Fig. 4 is a sectional vieW along line 4--4 of Fig. 3;

Fig. 5 is an enlarged top plan view of the portion of the gun shown in Fig. 3, with the guard plate removed;

Fig. 6 is a top plan view of the cross member at the forward end of the gun; and

Fig. 7 is a front view of the cross member.

Referring to the drawings, and more particularly to Figs. 1 and 2, the arrow projecting gun comprises a stock 1, and a fore stock portion 2, having a barrel member 3 formed integral therewith, the front end of the barrel having a rigid cross-member 4 secured thereto. As will be seen in Figs. 6 and 7, the cross-member 4 is provided with slots 5 adapted to receive the ends 6 of a piece of rubber tubing 7, forming the sling member, the ends of the tubing being frictionally held in seated position in the slot by means of suitable wedge members 8 fitted into the ends of the tubing. It will be noted that the sides of the slots are tapered inwardly, as viewed from the front of the cross-member (Fig. 6), and accordingly, when the tubing is stretched to cocking position the members 8, which are formed with a taper complementary to the sides of the slots, securely wedge the ends of the tubing in seated position in the slots. The closed end, or loop portion 9 of the tubing 7, is reinforced, as by Winding with cords or other suitable material, to provide an arrowengaging portion of smaller diameter than the remainder of the tube.

The barrel 3 of the gun is formed with a groove 10, adapted to receive an arrow 11, the bottom of the groove having a contiguous slot 12, designed to accommodate one of the feather guides 12 at the rear of the arrow, when the arrow rests in the grooved portion 10. The rear of the barrel (Fig. 5), is rounded as shown, and forms the front wall of a cut-out portion in the upper surface of the fore stock, the rounded Wall having a metal strip 13 secured thereto so as to present a smooth surface of contact for the loop of the sling. The fore stock is suitably recessed in portion 14 thereof to provide a guide for a trigger member 15. As will be seen in Fig. 4, the trigger 15 is pivotally mounted on the stock by means of a pin 17, and is connected to a plunger 16 by a pin 18, the trigger being biased to its normal non-firing position by a spring 19, which surrounds the plunger.

In order to maintain the arrow in seated position in groove 10 of the gun barrel, there is provided a guard member, designated generally by numeral 20, comprising a plate 21, having an offset 22, and terminating in a reduced end 23, the offset portion of the plate and its integral reduced end 23 being spaced in overhanging relation with respect to the grooved -fore stock. Att-ached to the plate 21 and projecting through the slotted portion 20 of the offset is a spring member 24, the free end 25 thereof being biased downwardly in the direction of the barrel groove so as to engage with the end of the arrow when the arrow is in firing position on the gun barrel. It will thus be seen, that when the arrow is in ring position, the end portion beyond the feathered guides seats under the linger of spring member 24, and is securely clamped between the finger and the barrel. It will also be noted that the reduced end 23 of plate 21 overhangs the slotted portion of the upper surface of the fore stock, and overhangs the arrow, thus perventing the loop from rising above the end of the arrow, when the gun is tired.

Sighting means comprising a sight rod 26 may be provided. In the arrangement shown, the fore stock is bored a suicient depth to receive the rod, which is notched at 27, and held in adjusted position by means of a detent or plunger 28, biased to seated position by a spring 28'.

In use, the gun is cocked by stretching the tubing until the loop portion 9 can be seated in the cut-out formed in the top portion of the fore stock. When so seated, the inner surface of the loop is in contact with the metal strip 13 attached to the rounded front wall of the cut-out. The arrow is then placed in the grooved portion 10 of the barrel, with one of the feathered guides projecting into the slot 12, and then moved rearwardly of the barrel until the end beyond the guides fits under finger member 25. When it is desired to project the arrow, trigger 15 is pulled in a direction to move plunger 16 upwardly and lift the loop out of the recess and in contact with the end of the arrow and project the same.

While I have shown and described the preferred embodiment of my invention, I wish it to be understood that I do not confine myself to the precise details of construction herein set forth by way of illustration, as it is apparent that many changes and variations may be made therein, by those skilled in the art, without departing from the spirit of the invention or exceeding the scope of the appended claims.

I claim:

1. An arrow projecting gun of the character described, comprising a stock and a fore stock portion having a barrel member formed integral therewith, a rigid upwardly bowed cross-member attached to the front end of the barrel, said cross-member having an open-ended vertical slot formed in the vicinity of each of its ends, the barrel having an arrow receiving groove formed in the upper surface thereof, said grooved barrel terminating in a rounded end forming the front wall of a cut-out portion in the upper surface of the fore stock, a plunger constructed and arranged for vertical movement within said cut-out portion, means to actuate the plunger comprising a trigger pivotally mounted in the fore stock and operatively associated with the plunger, a piece of rubber tubing having a wedge member in each end thereof and having a reinforced central arrow engaging portion of smaller diameter than the remainder of the tube, the wedge ends of the tube being seated in the slots formed in the crossmember at the front end of the barrel, the reinforced loop portion of the tube, when said tube is stretched to cocked position, being seated in the Cut-out portion against the rounded front wall thereof, and means to prevent the tube from rising above the end of anarrow adjacent said front wall, when firing, comprising a plate attached to the upper surface of the fore stock, said plate having an offset portion terminating in a reduced free end portion, said offset and end portion being arranged in spaced over-hanging relation with respect to the grooved portion of the fore stock.
