The inclined or tapering sides of the blade 24 cooperate with the inclined sides ll of the arcuate groove H3 in the shank of the spike to prevent lateral displacement of the key relative to the shank and to form an interlocking connection between the key and shank as shown in Figure 1. The offset head 22 of the key I8 is disposed at the outer side of the spike head to facilitate gripping engagement thereof for the forceful removal of the key, should it be desired to remove the spike from the tie.

In the form of invention shown in Figure 3, the groove [4a at the rear side of the shank 12 for the sliding reception of the key I8 is formed at an angle to the longitudinal axis of the shank to increase locking engagement between the key and shank.

In the form of invention shown in Figure 6, the shank l2a of the spike has a substantially transversely extending arcuate groove 1 6a. at the rear side thereof .and the top and bottom walls of the groove Ilia are slotted or serrated as at 25 with the serrations in each wall driven into contact with each other from one side of the shank and at one end of the groove to provide a more definite entrance into the groove for the end of a locking key.

The shank |2b of the spike shown in Figure '7 has a reduced lower end I20 forming opposite pointed shoulders 26 that cooperate with the pointed end 21 of the shank to facilitate the driving of the spike into a tie, the shank l2b being provided with a rear corner edge groove Nb and an arcuate cross groove |6b for the reception of the key l8 as shown in Figures 1, 2, 4 and 5.

From the above detailed description of the invention, it is believed that the construction and use thereof will at once be understood, and while there are herein shown and described the preferred embodiments of the invention, it is never theless to be understood that minor changes may be made therein ,withoutdeparting from the spirit and scope of the invention as claimed.

I claim:-

1. In a railroad spike of the character described, a spike having a shank and an offset head, the shank of the spike having a groove in the rear wall thereof extending downwardly through the head and merging into an arcuate groove extending across the shank at a point intermediate the upper and lower ends of the shank, in combination with a key for locking the spike in a wooden tie comprising a shank of the same cross-sectional shape as said groove with the free end of the key projecting through the arcuate groove at the other side of the spike, and a laterally extending blade carried by the key shank adapted to be moved into arcuate formation opposite the arcuate groove and projecting laterally of the spike for biting engagement in the tie.

2. In a railroad spike of the character described, a spike having a shank and an offset head, the shank of the spike having a groove in the rear wall thereof extending downwardly through the head and merging into an arcuate groove extending across the shank at a point intermediate the upper and lower ends of the shank, in combination with a key for locking the spike in a wooden tie comprising a shank of the same cross-sectional shape as said groove with the free end of the key projecting through the arcuate groove at the other side of the shank, and a laterally extending blade carried by the key shank aadpted to be moved into arcuate formation opposite the arcuate groove and projecting laterally of the spike for biting engagement in the tie, the arcuate groove having a flat bottom wall and converging side walls to form an interlocking connection with the key.

3. In a railroad spike of the character described, a spike having a shank and an offset head, the shank of the spikehaving a groove in the rear wall thereof extending downwardly through the head and merging into an arcuate groove extending across the shank at a point intermediate the upper and lower ends of the shank, in combination with a key for locking the spike in a wooden tie comprising a shank of the same cross-sectional shape as said groove with the free end of the key projecting through the arcuate groove at the other side of the shank, the top and bottom walls of the arcuate groove being serrated with the serrations in each wall moved into engagement in one direction transversely of the shank to define an entrance opening for the entering end of the key.
