R. B. EVATT ARROW Filed Deo. 20, 1946 oct. 9, 1951 Inventor Easem- B- m-rr Patented Oct. 9, 1951 UNITED STATES PATENT: OFFICE ARROW v Y, Y Robert B. Evatt, Barrington, Wash. i Application December 20, 1946, Serial No. 717,562 A i` 4 Claims. l

This invention relates generally to arrows, and more particularly to an arrow having a pointed head constructed from flat stock and centrally slotted so that this slot communicates with a hollow shaft, for the purposes hereinafter specied.

An object of this invention is to provide an arrow so designed and engineered as to make it practicable to manufacture the arrow entirely or largely of metal.

Another object of this invention is to provide an arrow in which the shaft is hollow thus decreasing air resistance and providing for straighter and longer flight of the arrow.

Another object of this invention is to provide i an improved means of securing the head to the shaft of an arrow. s

And a last object to be specifically mentioned is to provide an arrow which is inexpensive to manufacture, convenient to use, and which is suiciently sturdy to give durable and ecient service.

With these and other objects in view as will appear hereinafter as this description proceeds, this invention resides in certain novel features f construction, combination and arrangement of parts as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings which form a material part of this application, and in which:

Figure 1 is a top plan view of the assembled arrow, the shaft being broken and foreshortened to conserve space;

Figure 2 is a View of a portion of the shaft and head of the arrow, portions thereof being broken away and the underlying parts shown in section to indicate the structure thereof; Y

Figure 3 is a view of the forward end of the arrow as illustrated in Figure 1 but with the structure turned through an angle of 90;

Figure 4 is an end elevational View of the arrow taken from the front end of the arrow; and

Figure 5 is a sectional view taken on the line 5 5 in Figure 3.

Similar characters of reference designate similar or identical parts and portions throughout the specification and throughout the several views of the drawings.

Referring now to the drawings in detail, which drawings represent only one preferred embodiment of this inventive concept, it will be noted that the arrow comprises a head I0, shaft I2. ferrule i4 and vane I6.

The head is pointed and substantially uniform in thickness and is formed with a longitudinal (Cl. 27g-106.5)

slot I8 extending from adjacent the point of the head to the rear edge thereof, the rear portion of the head being preferably tapered as at 20. A tubular member referred to herein as the ferrule i4 is formed integral with or secured as by welding to the rear tapered portion 2U of the head and within the slot I8, the ferrule having diametrically disposed recesses 22 to accommodate inner portions of the head I0. The hollow shaft i2 is constructed of light metallic tubing and is of a diameter to t snugly within the ferrule i4 and the front ends of the ferrule and the shaft are outwardly crimped together, whereby the head IS is rigidly secured to the shaft l2. It will be noted that the above described construction provides for alignment of the slot I8 and the hollow shaft l2. In this connection it may be noted that the crimping is preferably accomplised in a manner providing for the slight expansion of the end of the tube i2 within the turned portion 23 of the ferrule to increase the rigidity of this connection. The butt end 2li of the arrow is formed with a diametrically disposed slot or notch 26 to facilitate the alignment of the butt end with a bow string. A plurality 0f vanes i5, disposed at an angle of to each other, when the usual three vanes are supplied, are constructed of thin metal plate cut according to conventional configuration for such vanes and these metal vanes will normally be welded to the shaft I2.

In operation, this arrow will be used in substantially normal manner except that the hollow shaft will enable longer flight, expecially when the weight of the arrow is maintained at a minimum by the use of modern very light alloys in the construction thereof.

Though there has been shown a particularembodiment of this invention, this application is not limited to this particular embodiment, but it is desired to include in the scope of this invention the construction, combination and arrangement of parts and portions substantially as set forth in the appended claims.

Having thus described this invention, what is claimed as new is:

l. An arrow including a head comprising a flat plate having a single point and an axial slot extending along a major portion of the length thereof, said slot having a closed end adjacent said point, a hollow shaft communicating with that end of said slot remote from the point of the head, and means securing said shaft to said head.

2, An arrow including a head comprising a flat plate having a single point and an axial slot extending along a major portion of the length thereof, said slot having a closed end adjacent said point, a hollow ishaft communicating with the rear end of said slot, and means securing said shaft to said head.

3. An arrow including a head comprising a flat plate having a single point and an axial slot extendingzalong a major portionnfithelength thereof, saidslot@having-a;- closed endadjaoentf said point, a hollow shaft communicating with the rear end of said slot, and a ferrule on the forward.-

end of said shaft securing the shaft to said head While maintaining said communication.

4. An arrow comprising a pointediheadiwith,

laV Y an axial slot extending along a major portion of the length thereof, a hollowushaftccommurcating. with the rear end of said slot, said head, being;

4 formed from flat stock, and an integral ferrule on the forward end of said shaft for securing the shaft to said head by outwardly crimping the forward ends of the ferrule and shaft while maintaining said communication.
