of a locking member arranged to cooperate with the spike proper: and in the application of such locking member force the-spike proper to cause a'portion thereof to be driven into the material of the tie, the locking member, when in fully operative position, cooperating with the spike proper, so as to interlock therewith to prevent acc1-. dental separation of the spike proper and locking member. i In the drawings 7 Fig. 1 is a perspective view showing the spike and interlocking member in spaced relation;
Fig. 2 is a vertical sectional view partly in elevation illustrating the cooperating application of the improved spike and locking member.
The improved spike is made up of two members, a spike proper 1 and a locking member 2. The spike proper is of the usual dimensions having the driving point'3 and head 4:. Below the head the spike is formed on one side with a projection 5 having an outer inclined surface which merges into the surface of the spike at the lower end of said projection. The upper edge of the projection presents an abrupt surface 6 at substantially right angles to the spike surface.
That surface of the spike proper opposite the projection 5 is formed immediately below the head with a recess 7. The cooperating or locking member 2 is of substantially similar form to that of an ordinary spike, though of less dimensions, the inner surface 8 of the locking member being plane throughout its length, except at its upper portion, while the outer surface of the locking member is tapered at the lower end at 9 to fern 1 a point. The locking member has a head 10, the inner margin of which is in the form of a projection 11 adapted to cooperate with the recess 7 in the spike proper, the inter- Specification of Letters Patent.

locking member immediately below the projection being recessed as at 12 to avoid interference member. I
The rail 13 is designed to besupported on a usual bed plate 14 which immediately beyond the edges of the rail base is formed with spike receiving openings 15. These openings are substantially equal in that dimension transversely of the rail to the combined width of the spike proper and interlocking member. v Initially the spike proper is passed through the elongated opening 15 and into the tie 16, the movement being continued until the head of the spike proper rests upon the upper surface of the rail base. The proportions are suchthat in this position, the pro- 'jection 5 of the spike proper isbelow the upper surface of the tie.
her 2 is then driven into forces the upper end of into intimate contact with the remote edge of the opening 15, at the same time forcing the projection 5 laterally into the material of the tie. The interlocking member is driven into a position which will permit the projection 11 thereof to rideinto the recess 7 of the the spike proper and interlocking member will so completely fill the opening 15 in the The locking memthe opening and the spike proper plate that accidental separation of the parts s practically impossible. The plane surface 8 of the interlocking member bears squarely against the adjacent surface of the spike proper, thus tending to move the spike proper bodily and to align it vertically with respect to the rail. Theprojection 5 of the spike proper has been of course forced laterally into the material of the tie, thus forming a recess for itself in the material of the tie, which will. materially ing accidental upward spike proper.
I claim 1 A railroad spike comprising a spike proper having a. lateral projection and an engaging member adapted to be driven lengthwise the spike proper-"to force the projection of the spike proper into the material of the tie, the spike proper being formed with a recess and the engaging member havinga projection to seat in; said recess when the parts are in cooperative relation.
In testimony whereof I afiix my signature.
