SPIKE Filed Aug. 9, 1946 lm/emor Bunnosulfe Omozo Patented July 4, 1950 UNITED STATES ATENT OFFlCE 1 Claim.

This invention relates to a spike and has relation more particularly to a device of this kind especially designed and adapted for use in connection with rails, and. it is an object of the invention to provide a spike having a head wherein the top face is level so that the spike will not jump away when being driven with a spike maul and wherein is substantially eliminated liability of the head breaking or chipping away when either driving in or pulling out with a claw bar.

The invention consists in the details of construction and in the combination and arrangement of the several parts Of my improved spike whereby certain important advantages are attained, as will be hereinafter more fully set forth.

In order that my invention may be better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure 1 is a view in side elevation of a spike constructed in accordance with an embodiment of the invention;

Figure 2 is a view in top plan; and

Figure 3 is a transverse sectional view taken on the line 3--3 of Figure 1.

As illustrated in the accompanying drawings, the spike comprises an elongated shank I of desired dimensions and which has integral with its upper extremity a long head H. This head I-I extends at one end, as at 2, to one side of the shank I to overlie the flange of a rail and in order that such extended portion 2 may have proper contact with the top face of the flange of a rail, the under surface 3 thereof is disposed on an upward and outward angle complemental to that of the top surface of the flange of a rail. The opposite end of the head is flat and is in the plane of the adjacent face of the shank, which end of the head and face of the shank form the back of the spike.

The head H is provided with a flat top face 1 extending from one end of the head H to the other. The plane of the fiat face 4 is substantially at right angles to the longitudinal axis of the shank I.

The head H is beveled along the sides and around the end remote from the shank as indicated at 5, which bevel forms a shoulder which merges directly with the under out side faces 6, which, in turn, merge, at the shank end of the head, with the sides of the shank I. This formation of the sides of the head H provide the downwardly converging side surfaces a with which can be effectively engaged the jaws of the usual claw bar employed for drawing out a spike and the portions 5 and 6 result in a solid head structure which will not break or chip away, thus substantially eliminating liability of injury to persons in close proximity to the working operation as often occurs with spikes of the kind now generally in use. This provision of the portions 5 and 6 is of the same advantage when the spike is being driven in by a spike maul or other implement.

It is to be pointed out that the edge or corner I) of the head H, at each side, is disposed laterally beyond the side face of the shank l or, in other words, the head H is of maximum width between opposite side corners b, which width is greatly in excess of the corresponding dimension of the shank I. It is to be further noted that the corners I) extend equal distances beyond the sides of the shank I.

From the foregoing description it is thought to be obvious that a spike constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated.

I claim:

As a new article of manufacture, a spike comprising a shank and an enlarged head, said shank being square in cross-section and tapering downwardly from said head, said head being elongated and having its top and the side of its outer end fiat, said side being continuous with the adjacent side of said shank, the inner end of said head extending laterally from said shank, the opposite sides of said head being downwardly and inwardly angled and merging into the adjacent sides of said shank, the under side of said extended end being flat and upwardly and outwardly inclined correspondingly with the angle of inclination of the flange of a railroad rail, and the flat top having its side and inner end edges beveled to prevent chipping when the head is subjected to driving blows.

BUNNOSUKE OMOTO.
