SPIKE;
Specification of Letters Patent.
Patented May 19, 1914.
Application filed December 27, 1913. Serial No. 809,072.
TO aZZ whom, it may concern Be it known that I, SAMUEL C. 7001), a citizen of the United States, residing at Canton, in the county of Haywood and State of North Carolina, have invented new and use ful Improvements in Spikes, of which the following is a specification.
This invention relates to railroad spikes and has for its primary object to provide a spike of this character which is constructed so that its head will be braced by the cross tie in which it is engaged in such a manner that it is not apt to be broken or bent by the lateral strain upon the track rail with which it is engaged, as is often the case in the use of spikes of ordinary construction.
A further object is to provide a spike having a reinforcing member formed upon its head and connected with the body of the spike for engagement with the tie, the said reinforcing member being disposed oppositely with respect to the rail-engaging portion of the spike head.
A still further object of the invention is the provision of a spike of this nature, wherein the reinforcing member extends longit'udinally with respect to the spike body and is connected therewith by means of a tapered web, which serves to prevent the spike from extracting pieces of wood from the tie when the spike is withdrawn therefrom.
The invention consists in the features of construction, combination, and arrangement of parts, hereinafter fully described and claimed, reference being had to the accompanying drawing, in which:
Figure 1 is a side elevation of the spike in use; Fig. 2 is a top plan view; Fig. 3 is a rear elevation; Fig. 4 is a horizontal sectional view on line 4- l of Fig. 1; and, Fig. 5 is a longitudinal sectional view on line 5-5 of the same figure.
In the drawings, the numeral 1 designates the elongated body of the spike which is preferably rectangular in cross section and has its lower end pointed. A comparatively massive head 2 is formed upon the upper end of the body 1 and projects forwardly from the body to provide an engaging portion 3, and it also projects rearwardly from the body and has a longitudinally extending reinforcing member a formed integral with this portion so as to depend therefrom. This reinforcing member or scotch has its inner face 5 tapered upwardly and inwardly toward the body, with which it is connected by means of a web (3. This web terminates above the lower, tie-engaging end 7 of the member f and is tapered downwardly.
The spike is adapted especially for railroad use and is intended to serve as efficientmeans for securing a track rail to one of the supporting cross ties. In this use, the body is driven vertically into the tie in engage ment with the adjacent base flange of the rail to such an extent that the engaging por tion 3 of the spike head is brought into engagement with the upper face of the said flange. The reinforcing member will thus become engaged within the tie to a considerable depth and the connecting web 6 will also sink into the tie. The head of the spike will be reinforced efi ectively by the member 4: so as to eliminate the danger of the head being broken off by the lateral strain upon the track rail. hen the spike is withdrawn from the tie for any purpose, the reinforcing member at and the web 6 will become disengaged from the wood of the tie Without extracting a chunk of the same, which would occur if it were not for the inclination of the inner face of the reinforcing member and the specific shape and disposition of the said web.
What is claimed is:
A spike comprising an elongated body, a head formed upon one end of the body and being extended forwardly and rearwardly from the body, a longitudinally extending reinforcing member projecting inwardly from the rearwardly extending portion of the head, and a medially disposed web connecting the said reinforcing member with the body of the spike and terminating inwardly from the free end of the said memher, the said web being tapered toward its free edge.
In testimony whereof I affix my signa ture in presence of two witnesses.
SAMUEL C. WVOOD.
