Oct. 14, 1952 T. B. DALTON RETRACTABLE ARROW POINT Filed May 7, 1949 own INVENTOR. Tfiomas fiaizurlor'e Fa ftbrz Patented Oct. 14, 1952 RETRACTABLE ARROW POINT Thomas Baltimore'Dalton, Montague, Mio'lL, assignor to Valley Research Corporation, -Montague, Mich, a corporation of Michigan Application May 7, 1949, Serial No. 92,026 3 Claims. (01. 2731oe;5

My invention relates to sporting equipment and more particularly to a retractible field arrow point. Most sportsmen have experienced much difficulty in extracting arrows from a target, such as trees, stumps and the like, or other medium hard wood targets, due to the fact that the arrow point is so firmly wedged into the target it is extremely diflicult to loosen same without breaking the arrow shaft. .1

An object of my present invention 1s to fac111- tate the removal or retraction of an arrow from a target in which the arrow point 15 firmly embedded by constructing spiral grooves in the tapered arrow point so that same can be readily unscrewed from the target.

For a more detailed understanding of my 1nvention, reference may be had to the accompanying drawing illustrating a preferred embodiment of my invention, wherein like characters refer to like parts throughout the several views, and in which:

Fig. l is an elevational view of a field arrow equipped with my novel arrow point.

Fig. 2 is an enlarged elevational new of the 51 3 is a transverse sectional view taken on the line 33 of Fig. 2, and

Fig. 4 is an enlarged longitudinal sect1onal view of the point showing the grooves filled w1th a soapy like substance.

A field arrow as used in the sport of archery comprises a shaft in and a point II which 1s secured in any suitable manner to the end of the shaft.

The arrow point incorporating the principles of my invention and which makes for easy retraction of the arrow from the target, comprises a metal member provided with a cylindrical shaft portion l2 recessed as at l2a. to receive the end of the arrow shaft that is usually cemented to the point but which may be pinned thereto by pin I3 or secured rigidly thereto in any other suitable manner. The forward end portion of the arrow point is generally tapered, as shown and terminates in a point I l. The tapered portion is provided with a rounded spiral groove l5 and at the base of the tapered portion the two portions of the arrow point are merged together by a generally outwardly fiared portion which provides a seat limiting the penetration of the point into the target.

This tapered arrow point is usually very firmly wedged into the target and it is sometimes difficult to remove from the target. With conventional field arrows, one must use pliers or some other suitable tool with which one can securely grasp the point. Generally the points are merely cemented to the shaft and if one attempts to remove the arrow without grasping the point itself, the shafts are invariably pulled out of the point leaving the point embedded in the target. The spiral grooves embodied in the tapered portion make it possible to readily extract or remove the arrow from the target by simply unthreading the arrow. The rounded formation of these rooves facilitates the removal of the arrow point from the target.

In order to further facilitate removal of the arrow point from the target, these grooves are preferably filled with a plastic or soapy like material it flush with the outer periphery of the threaded portion. This substance is readily stripped out of the grooves, and is removed at least in part when the arrow point penetrates the target and is partially stripped out when the arrow point is unthreaded from the target, but enough is retained in the grooves to aid in removing the point from the target several times.

It will be noted that dirt in the grooves may be more readily removed from points with rounded ridges, and the points with rounded ridges seem to turn easier. In removing the arrow from the target, the minute one twists the arrow counter-clockwise, the pressure of the wood against the point, due to the wedged shape of the point, is instantly relieved, because of the tapered threads which backs both out and away from said pressure. The lubricant applied to said points reduces friction and facilitates the start of the first turn in unthreading the arrow from said target.

It will be apparent to those skilled in the art to which my invention pertains that various changes in structure and other modifications may be made therein without departing from the spirit of my invention or from the scope of the appended claims.

I claim:

1. An arrow point for application to the end of an arrow shaft, comprising a solid one piece metal member of generally tapered construction terminating in a relatively sharp point to facilitate the penetration of the arrow point into a target, the surface of said tapered point portion provided with thread-like spiral grooves encircling the point portion whereby to provide means permitting said arrow point to be spirally retracted from said target.

2. An arrow point for application to the end of an arrow shaft, comprising a solid one piece metal member of generally tapered construction terminating in a relatively sharp point to facilitate the penetration of the arrow point into a target, the surface of said tapered point portion provided with thread-like spiral grooves encircling the point portion whereby to provide means permitting said arrow point to be spirally retracted from said target, said arrow point provided with a rear cylindrical portion to the rear of the tapered portion, the junction of said tapered and cylindrical portions providing a seat serving to limit the penetration of said arrow point into the target.

3. An arrow point for application to the end of an arrow shaft, comprising a solid one piece metal member of generally tapered construction terminating in a relatively sharp point to facilitate the penetration of the arrow point into a target, the surface of said tapered point portion provided with rounded thread-like spiral grooves,

4 encircling the point portion and comprising a retractible threaded point, said rounded grooves offering a minimum of resistance to the removal of the arrow point from the target.
