UNITED STATES PATENT OFFICE SAMUEL c. ALLE or NEAR DAYTON, OHIO, AssIoNOn TO THE DAYTON s'rnm. RAG;

oun'r COMPANY, or DAYTON, OHIO, A CORPORATION OF OHIO METAL ARROW AND METHOD or MAKING THE sAME Application filed May 3,

This invention relates to new and useful improvements in metal arrows and the method of making the same It is one of the principal objects of my invention to provide a metal arrow which is light-,strong, straight, elastic and resilient, and whose flight is steady, unwavering, and smooth. The tubular metal shaft is grooved for fietching, the nocks are correct and the tips will split wood without being bent or loosened. 1

Another object of the invention is to provide a method of making these arrows from vbe brought out in the following specification and particularly set forth in the subjoined claims.

In the accompanying drawing illustrating my improved metal arrow and its method of manufacture, Figure 1 is a perspective view of one end of the tubular steel shaftbefore it is grooved. Figure 2 is a perspective view of the same after it is grooved for fletching. Figure 3 is a cross-sectional view taken through the grooved end of the shaft on the line 3-3 of Figure 2. Figure 4 is a longitudinal sectional view taken through the rear end of the tubular shaft, showing how the nook is applied to it. Figure 5 is an end view thereof. Figure 6 is a longitudinal View taken through the front end of the tubular shaft, showing how the pile is soldered into it. Figure 7 is an end View of the pile. Fi ure 8 is a perspective view of the fletching fixture, showing how the feathers are applied to the grooved end of the steel shaft within it. Figure 9 is a cross-sectional view showing how the vein of a feather is held in a groove by the pins of the fixture during the gluing operation. And Figure 10 is a perspective view of the rear end of the steel shaft after the nooks and feathers have been applied to it.

Themetal arrow illustrated in these drawlngs 1s madein the following manner. First,

a plain tube 1 that is preferably constructed of'alloyed steel is out ofi to the desired length The tube should not be too light to hold up underextreme conditions of use, and in the present instance should not be under five-eighths of an ounce.

One end of the tube is then formed with three axial grooves 2 to receive the veins of the feathers thatare applied in a fietching fixture to be hereinafter described.

The tube which is grooved as shown in Figures 2 and 3, isthen cut to the exact length desired, which in the present instance is 21 inches.

The tube is then heatetreated and polished,

, after which it is straightened by passing it between rollers or other means to remove the kinks.

The insidesurface of the end of the tube 1 opposite its grooved end is then polished to receive the reduced cylindrical part 3 of a hardened steel pile 4, which is soldered in place within the tube (see Figures 6 and 7). This end of the tube is then polished.

The tubular shaft 1 is then re-straightened to take out any kinks which were not removed a in the first straightening operation.

The shaft is then nickel plated, after which it is ready for the application of the feathers bysandblasting the grooves 2 to remove the dirt from them.

The fietching operation is performed with the assistance of a fixture such as the one which will now be described. Referring to Figures 8 and 9, the numeral 5 designates a side member to which two end blocks 6, 6 are secured to provide an arrow receiving frame. The end blocks 6, 6 are formed in their top edges with grooves 7 7 to receive the steelshaft 1 to support it during the application of the feathers to its grooved end.

A feather 8, is applied as follows: The tube 1 is placed in the fixture with a groove 2 facing upward as shown in Figures 8 and 9. Glue or other suitable adhesiveis then applied to the rib of the feather, which is then set in the groove. This is then held in iece 9 are )ll'lS 1O Jreferabl three in numl r bar, which are adapted to pass through a feather just-above itsrib to press the latter firmly in the top groove 2 of the tube. Sulii cient tens on for this purpose is applied to the holding pieceby a helical spring 11secured between it and the side member 5.

Jitter the rib of the feather 8 becomes fixedly setin the upper groove 2 of the tube,

the holding piece o'israised against the tension of-thespring 11 towithdraw the pressure pinsfrointhe' feather so that the tube may be turned to bri-n another groove 2 into position to receive aieather 8. The time consumed in applying a. feather to the tubular shaft 1 in the fletching fixture is from 15 to 20 minutes,

After all the feathers have been applied to the grooved end ofthe tube 1, they are cut to the style. desired. Thetube is then removed from the iletching frame and its grooved end cleaned and rust prooi edon the inside. This endof the tube'is then nickelplated I c Thenext operation 18 the nsertlon of a nook 12 in the grooved iend ofthe tubular shaft. films nock that is preferably made of aluminunnhas a reduced inner end 13 which has tight'fit in the end of the tube.
