May 29, 1962 R. SWAILS RETRACTABLE ARROW Filed Aug. 31, 1959 FIG?) ROY SWAlLS INVENTOR.
United States Patent 3,036,396 RETRACTABLE ARROW Roy Swails, 335 31st Ave., East Moline, Ill. Filed Aug. 31, 1959, Ser. No. 837,144 14 Claims. (Cl. 43-6) The present invention relates generally to arrows and more particularly is concerned with arrows used by sportsmen in hunting fish, game and the like.
The object and general nature of this invention is the provision of an arrow provided with retractable barbs and manually operated means for retracting the barbs when the arrow is embedded in the body of the game, such as a fish or animal, so as to facilitate the withdrawal of the arrow without entailing unnecessary tearing of the flesh. A futher feature of this invention is the provision of barbretracting means extending through the shaft of the arrow to the feather end thereof.
Another object of this invention is the provision of a barbed arrow with means to yieldably hold the barbs in extended position but in which the barbs automatically retract When the object is struck by the arrow. Another feature of this invention is the provision of means facilitating the disassembly of the several parts, as for repair or replacement.
Further, a more specific feature of this invention is the provision of a hunting or fishing arrow in which normally extended parts in the form of barbs are automatically retracted when the arrow pierces the game but which are automatically extended when the arrow isembedded in the object struck, with manually operated means accessible at the feather end of the arrow for retracting the barbs to make it easier to withdraw the arrow. These and other objects and advantages of my invention Will be apparent to those skilled in the art after a consideration of the following detailed description of the preferred structural embodiment of my invention, taken in-conjunction with the accompanying drawing in which the preferred form of my invention has been illustrated. In the drawing:
FIG. 1 is a longitudinal sectional view taken through the central portion of an arrow incorporating my invention.
- FIG. 2 is a cross section taken along the line 22 of FIG. 1 showing in particular the pivoting of the barbs to the barb carrier.
FIG. 3 is a fragmentary sectional view, similar to FIG. 1 showing the barbs in the position they occupy when they are manually retracted.
FIG. 4 is a view similar to FIG. 3 showing the way in which removal of the point member from the shaft facilitates disassembly of the arrow parts.
FIG. 5 is a side view of a modified form of arrow head.
Referring first to FIG. 1, the arrow of this invention comprises an elongated tubular shaft 10, which may be formed of aluminum or the like, having feathers 11 at its rear end. At its front or head end the shaft carries or is formed with a socket or chamber portion 12 having an enlarged interior space 13 that is generally square in cross section, as shown in FIG. 2. This provides a shoulder 14 to which detailed reference will be made below. The forward end of the chamber 12 is closed by a point member 15 having a squared shank 16 fitting into the outermost end of the chamber 12. The walls of the chamber 12 are apertured to receive a pin 17 that extends through an aperture in the point shank 16. The pin 17 is removable by any suitable means. The space 13 at its rear portion opens into the interior portion 18 of the tubular shank 10. Opposite portions of the walls of the chamber 12 are provided with slots 19 to receive barbs described below.
Disposed within the space 13 of the chamber 12 is a barb carrier 23 which comprises a member that is generally square in cross section and closely interfits in and is slidable generally longitudinally of the chamber space 13. The barb carrier 23 is provided with a longitudinal slot 24 that lies in the plane of the two associated chamber wall slots 19, the slots 19 and 24 thus being in registry. A rod section 25 is fixed to or formed integrally with the barb carrier 23 and'extends the full length of the tubular shaft 10 and outwardly the rear end thereof, as shown in FIG. 1. The outer end of the rod section 25 is provided with a bowstring-receiving notch 26.
A pair of barbs 28 are disposed in the slots 19 and 24 and are mounted on a pivot pin 29 carried in apertures 30 in the side portions of the barb carrier, adjacent the forward end thereof. 'When the barb carrier 23 is disposed in its rear position (FIG. 1) with its rear end 31 against the shoulder 14 a spring member 32, which has its ends pivoted in openings formed in the barb members 28, acts to swing the barbs out through the wall apertures or slots 19 and into the position shown in FIG. 1. A coil spring 33 acts between the inner end of the point member shank 16 and the outer end of the barb carrier 23 for urging the latter to and holding it in the position shown in FIG. 1.
It will he noted that the barb-extending spring 32 is arranged in the slot 24 with the barbs 28 and that the walls of the slot 24 hold these parts against displacement. The rear end of the rod section carrying the rear notched'portion 26 extends rearwardly out of the tubular shaft a distance so that when the arrow is placed in the bow and the bowstring engaged in the notch 26, the bowstring does not contact the feathers 11, the length of the rod section being such that this is so, even though the energy of the released string may momentarily compress the spring 33. I
' After the arrow is shot and strikes its target, the point member pierces the object struck. This decelerates the point member but the inertia of the barb carrier 23 tends to cause the latter to continue its motion. This serves to compress the spring 33 and to move the latter toward the position, relative to the point member 15, shown in FIG. 3 and thus serves to retract the barbs 28. Thus, entry of the arrow into the body of the object is facilitated since at this'moment the barbs are retracted. However, as soon as the arrow is stopped, the spring 33 extends the barbs 28 whereby the arrow is firmly embedded. If, for example, the sportsman is shooting fish, he may tie a line to the shaft, and to this end the latter is provided with a groove 36 adjacent the chamber end of the shaft. The arrow cannot readily be withdrawn from the struck quarry so long as the barbs are extended, but according to this invention the barbs may readily be retracted merely by depressing the notched end 26 of the rod section so as to force the barb carrier 23 to the position shown in FIG. 3 whereby the barbs are withdrawn into the slots 19. The arrow may then readily be pulled out of the fish or game. If it should be desired to repair or replace the barbs or any of the other parts, the arrow may be disassembled merely by punching out the pin 17 and removing the point member 15. This allows the barb carrier 23 and spring 33 to be removed from the interior of the chamber 12, the barbs being further retractable to a position within the space 13. For centering and holding the spring 33 in position suitable means, such as bosses 38, may be formed on the outer end of the barb carrier and the inner end of the point member 15.
The ready removability of the point member 15 accommodates changing the point member 15 for another member of different size and/or weight, such as the member 15a shown in FIG. 5 having a larger flange 40. However, the member 15a has a square shank 16a which interchanges with the shank 16.
It is to be understood that my invention is not to be 3 limited to the particular means shown and described above.
