Cowdery, Geneva, Ohio, assignor to The American Fork & Hoe Company, Cleveland, Ohio, a corporation of Ohio Application August 1, 1930, Serial No. 472,449

4 Claims.

My invention relates to arrows for archery, and relates more particularly to the provision of arrows adapted to be used for target and hunting purposes, and which may be produced in quan- 5 tities with uniformity in the qualities of weight,

balance, and straightnessas well as having uniform air friction effects.

'Heretofore, arrows have been made of many different materials, and efforts have been made to accomplish the production of an arrow metallic in whole or in part, and in which one or more of the above qualities was sought to be obtained.

These efforts have left much to be desired in the eifort for achievement of all of the above qualities in an arrow responding to therequirement of present day practice.

. For instance, at the present time an arrow adaptable for competitive target, clout and distant shooting, is usually about 28 inches long and may weigh the equivalent of 4 shilling and 9 pence in new English silver, and the bob-tail comprises three feathers each curving the same way and usuallyabout 1 /2, inches long and A inch deep, and preferably are made of seasoned red deal and although these may be self very often are footed; that is, a piece of hard wood to which the pile or point is attached is spliced to the deal shaft, which of course must be perfectly straight and stiff. This construction .involves the making of the shaft to a uniform diameter, of approximately 595 of an inch.

The archery associations have set up certain specifications, not differing greatly from the above, for arrows used in competitive archery, but it is found very difficult to make arrows of wood or other material suitable for the purpose, adaptable to conform to such specifications, and in using deal or other seasoned wood, diificulty is had in achieving the desired straightness, weight, and balance, and even more diiliculty is had in obtaining the desired straightness in an arrow after making, during, and pending use. Wood is very susceptible to warping and many expedients have been adopted, such as storing the arrows in a-closed case, whereby all sides of the arrow are exposed to the same temperature and humidity conditions. Archers, however, are prone to disregard the safe-guards which minimize but which may not prevent Warping, with the result that the arrows must be carefully selected before each competition, many being thrown out as unfit, which usually costs much in production and maintenance up to the time of competition.

An object of my invention is to accomplish the production of an arrow of a form capable of being made in quantities, with substantially uniform results as to weight, balance, and a high degree of straightness, and to provide for the mounting thereon of the necessary pile, a bob-tall, and nock.

Another object of my invention is to provide an arrow having the aforesaid qualities and which will maintain such qualities through indeter minate periods of use, or non-use and without requiring the care now required to maintain arrows free from warping.

Another object of my invention is to provide an arrow hardy enough to withstand the forces incidental to its use without substantial variation in form.

Other objects of my invention and the invention itself will become apparent by reference to the following description of a certain embodiment of my invention, illustrated in the accompanying drawing.

Referring to the drawins:--

Fig. 1 is an elevational view of an embodiment of my invention;

Fig. 2 is a artly cross-sectional elevational view of the embodiment of Fig. 1, such view illustrating substantiallythe actual size of the same;

Fig. 3 is a transverse sectional view taken on the line 33 of Fig.2;

Fig. 4 is a fragmentary view mostly in longitudinal section showing another construction of the pile.

Referring to Figures 1, 2, and 3, wherein like parts are designated by like reference characters, I show a shaft 1, formed of a light tubular metal material such as a seamless tube of steel having a relatively thin wall, and a diameter sufilciently small to render the same of light weight, while at the same time of sumcient wall thickness to insure durability thereof. The diameter of the shaft is preferably of equal diameter at each end of the same. I

At 6 I show an impact pile telescoped over one end of the shaft 1, and at 10 I show a neck formed on the opposite end of the said shaft.

In Figs. 1 and 2 at 6 I show an impact pile preferably in the form of a bullet head and formed of hollow steel or the like having a pointed conical or otherwise tapered end which preferably has a filling of lead as hereinafter described, and shown in Fig. 3. Said impact pile 6 has a pointed end projected over the end of the tube 1, said tube 1 having an end thereof reduced in its transverse dimensions at 7, the reduced portions 8 being telescoped into the end of the pile with the shoulder '7 thereof engaging the end of the pile, the pile preferably soldered to the tube at the joint 9. My construction contemplates a sealed engagement of the tube 1 with the pile 6 at the shoulder 7 and the joint 9 of the tube to absolutely prevent the ingress of moisture or the like.

At 10 I show a hook formed in the end of the shaft 1 ,by cutting aligned ushaped slots 11 in oppositely disposed. sides therein andfin bend-- ing the edges of the bifuroated portions of the shaft thus formed inwardly at 12 and 13,- and rounding the same at their extremities 14. The slots and rounded side portions may bemaehined and all sharp corners and burrs may be removed during such a machining operationflthereon, and accordingly the nock will not cut' or fray the bow stringinuse. 4 v A i g t A plug 15 of wood or other compressible ma terial may be forcibly inserted into the shaft bore 16, beyond the nook and thus form a stopper to prevent the ingressof moisture or water into the shaft andcthereby eliminating the possibility of the .tubular shaft rusting ori deteriorating from the interior outwardly.

'In Fig. 4 I have illustrated another embodiment 'ofmy invention showing a: pile construction which comprises inwardly swaging the end of the tubular shaft 2-at 3 to closely approximate a point land in then filling thesmallrecess remaining in the .end of the tube with lead .or the like, to insure proper balance of the arrow and plurality of feathers, preferably three in number, 1

equally spaced from each other, the quills 1.8 thereof being secured to the wrapped base by a suitable cement, gluef-"or the like adhesive material, and with the projecting ends of the further secured to the base by a thread spirally wound about the same and the shaftat 19 and' 20. The quills extend longitudinally along the shaft surface with the feather vanes 21 projecting radially thereof. Each'of these vanes is naturally bent Iin'a very slight curve in the same direction from their forward end toward their rear end and forms a screw propeller which may effect rotation of-the arrow during itsflight through the airand thus increase its precision and projeotability. -However, these vanes'may be-so secured that the natural curvature of the same reduced. i If desired, the edges of the vanes may be trimmed, as showng; however, they may be left with straight edges,

V I have found that a tubular shaft having a 7 length of 25 andF/ inches possessing a diameter of of an inch throughout itsentire length and having a wallithiekness throughout its length of sjubstahtially'LOO'lS of an inch is well adapted for use in the formationof an arrow, and I have found that an arrow ha'ving thes'ej dimensions gives highly" satisfactory results. This length addedto the "length of "pile and nook may'give desired total length of 28 inches. However, it to'be' understood that! may depart from the dimensions herein given and I do not wish to be limited to these dimensions, as they are given merely for the purpose of illustration and to impart a more thorough understanding of my invention. My completed invention is well adapted to conform to specifications in vogue promulgated by the various archery associations. I

It can be readily seen that all possible eare has been taken in my presentv invention, to secure an arrow adapted to withstandvariousclimatieconditions as well as the most rigorous of wear as I have provided improved means for sealing both ends of the shaft against the ingress of moisture and the like." The outer surface of the tubular shaft may also be. covered with a protective coating to prevent the [deteriorating effects of the elements from attacking the tubular shaft fromits exterior surface. A high metallic polish may be applied to the tubular shaft and thus decrease air friction of the arrow during its flight through the air, thereby increasing its range and precision.

Another method of fietching the arrow which may be used-if preferred in the instant arrowis, as, illustrated in my co-pending application'for United States Letters PatentJfiled July 5, 1927, bearing ,SerialNo. 203,425, of which thisifl plication is a:continuation- -in part. j "I T It is to be understood thatmy invention heremeta-llio arrow. having ansim'pactpile; preferably as noted-above in the: form of a bullet head and formed of hollow steel orthe like, having a pointed. end projected over the 'reducedend; of the tube,-,the reducedportion being telescoped into the end of'the' pile; and: to theprovis'lonof a nook formedbyxtheshaft and sealing an -end,

thereof. I v I My arrow may employ :a filling as indicated in my co-pending application, referred'to above, or other means to: deaden any ringing metallicsound which may result in the shooting of -the arrow.

Having thus described'my invention,'I am aware that numerous and extensive departuresmaybe made therefrom but without departing from thespirit of my invention; Iclaim:--

1. An arrow for archery comprising: almetallic tubular shaft,and a noekslot for'medin' one end of said shaft, the periphery of said slot having its bifurcated edges curved inwardly. r j
