` RAILWAY-SPIKE.

To a/ZZ whom it may concern."

Be it known that I, DAVID LAURENCE VAUGHAN, a citizen ofthe United States, residing at Haddonfield, in the 'county of Cam- New Jersey, have invented certain new and useful. Improvements in which the following is a full, clear7 and exact description, reference being had to the accompanying drawings, of which* l Figure l is a side elevation showing the 1spikeas in use. Fig. l2 is a rear elevation. ig. 3 is a front elevation. In railroad spikes of usual construction, owing to the lateral movements of the rails induced by the passage of trains, a transverse groove or recess 1s in time worn inl the part ofthe side or face of the shank of the foot of the rail, and when it becomes necessary to draw out and redrive the spike it can-- not, obviously by reason of said groove, be driven to brin theface in contact with thel edge of the rai -foot.

The obj ect of my invention is to provide'ak spike of simple construction that shall ,prevent the formation .ofsaid objectionable groove.

' ment maybe applied In the accompanying drawings I .have shown my improvement'app'lied to a spike of the general -construction of that shown and described in United States Letters Patent No. 691,087, issued January `14, 1902', to David Fvaughan for a railway-spike, although I 'do not wish to be understood as limiting ymyself to such construption, as the improve- 1n common use.

In said drawings, 1 is the part of the shank of a railway-spike which is driven into the tie,

(the top of which tie is indicated by the line t t, Fig. 1,) and 2 is the head of the spike, the

inner side of which overlies and contacts with the top of the footof the rail 5 when the spike is in use, as -in said Fig. v1. In carrying out my invention I make the part 3 of the inner side ofi-the spike-shank immediately below the head 2 an oHset-that is, its face is intended to contact with the edge of the a plane in advance of the plane of the face. of the lower portion of the shank 1 on the same side-the length of the said face of offset 3 being such, as clearly seen in Fig. 1, that whenthe spike is driven home in the tie the lower end'of this face will be above the surface of the tie-that is, above the base'ofthe foot of the rail. The lower end of the offset 3 is preferably beveled, as also seen in Fig. 1. e

.It is manifest that the objectionable groove hereinbeore referred to cannot be ormed in'a spike made in accordance with my lnvention, as the' said odset will be cut away by the action ofthe foot ofthe rail.

s I remark that my improved spikes may be readilyr made by cutting 0E the same from an Velongated bar of suitable metal rolled of the proper shape in cross-section in the manner described in said Letters Patent N o. 691,087.

Having thus described my invention, I claim as new and desire to secure by Letters Patent* A railwaylspike having the oiset immediately'below the `head,the length of which ofiset'is less than the distance from the under side of said head to the base of a rail, substantially as and for the urpose recited. y

In. testimony whereof I) have hereunto af- 'ed my signature.
