I Snugwtoz EZZZEZ/ZS Witnepoeo EMIL ERIKSON, OF EMIGRANT GAP, CALIFORNIA.
RAILROAD-SPIKE.
Specification of Letters Patent.
Patented Aug. 8, 1911.
Application filed May 24, 1910. Serial No. 563,189.
To all whom it may conccm:
Be it known that I, EMIL ERIKsoN, a citizen of the United States, residing at Emigrant Gap, in the county of Placer and State of California, have invented new and useful Improvements in Railroad-Spikes of which the following is a specification.
This invention relates to railroad spikes, and the object of the invention is to provide a spike having its front and rear faces formed with angularly V-shaped upwardly projecting teeth whereby the spike will be effectively retained in position upon a railway tie, and whereby the liability of the loosening of the spike due to the jar of the rolling stock passing over the track with which the spike is connected is efiectively obviated.
\Vith these objects in view the invention resides in the novel and peculiar construction of railway spikes hereinafter fully described and claimed.
In the accompanying drawings, Figure 1 is a front elevation of a spike constructed in accordance with the present invention. Fig. 2 is a rear elevation of the same. Fig. 8 is a side elevation of the same. Fig. 4L is a detail perspective view, illustrating the formation of the spurs.
In the accompanying drawings the numeral l designates the improved spike. This spike 1 has its front face 2 provided with V-shaped teeth or projections 3. These teeth 3 are arranged in pairs adjacent the side edges of the face 2 and extend inwardly and rearwardly at an angle toward the center of the front face of the spike. The teeth 3 are formed integrally with the spike and are constructed by cutting away the body of the spike to provide an arcuate line adjacent the points orbiting portions of the teeth. The body of the spike has its front and rear faces arranged at an angle toward the lower portion of the spike, and the extreme edges of the front and rear faces of the spike are beveled or V-shaped as clearly illustrated in Fig. 3 of the drawings, and whereby the spike may be readily inserted within a railway tie. The rear face 4 of the spike is also provided with V-shaped teeth 5, constructed in a similar manner to that of the teeth 3 provided upon the front face of the spike. These teeth 5 are preferably arranged below the lower teeth 3 of the front face so as to provide the spike with biting teeth arranged out of a plane with each other, and thus provide the spike with effective securing means arranged upon each of its faces which will prevent its accidental removal when inserted within a tie.
The head 6 of the spike is provided with a horizontal under face, and this face projects upon either side of the spike as well as at a sufiicient distance forward of the front face 2 of the spike.
It will be noted by reference to the several figures of the drawing that each of the teeth 3 and 5 provide substantially pyramidal spurs, the apeXes of which being adapted to enter the wood at the slightest upward movement of the spike and to compress the wood between the inclined inner faces of the said teeth and the faces of the spike. The wood is also forced between the inclined side faces of the oppositely arranged teeth so that the spike cannot be removed accidentally.
Having thus described my invention, I claim as new A railroad spike provided with parallel sides, beveled front and rear faces and an overlapping head, the front and rear faces of the spike being provided with integrally formed pyramidal teeth, the said teeth being arranged in pairs upon the opposite faces of the spike, the points of the teeth being positioned in a line with the sides of the spike, each of said teeth having its inner face inclined toward the face of the spike and its side or inner face beveled downwardly toward the central portion of the body of the spike to the point of juncture with the coacting tooth.
In testimony whereof I affix my signature in presence of two witnesses.
EMIL ERIKSON.
