The tie plates are to be double shouldered in the necessity for anti rail creepers.

order that the base of the rail may be made to A railroad spike made of spring material will engage the shoulders of the tie plate at each side compensate for a variation in tolerance that is of the tie plate arid at the'opposite edges of the customarily allowed in the width of the base of rail where the samerests uponthe tie plate. The the rail of the same rolling or of a different 55 rolling. Spikes -of my design further allow for a slightldifierence in tolerance in the position of the shoulders ofthe tie plate and of the position of the punched holes in the tie plate. Spring spikes also absorb, in a cushion like manner, the transverse movement of the loaded vehicle passing over the rails which are further the rail to absorb the'expansion and contraction of the 'rail within the elastic limits of the metal itself from which the rail is made.

Like reference characters refer to like parts throughout the several views;

I make my spike ofhigh carbon steel, and as illustrated in Figs. 1 to 4 inclusive, the spike is made slightly longer than the conventional spike.

I place an oifset in the body of the spike substantially below the head of the spike.

The inset 26 is made to engage the edge 21 of the base 28 of the rail. The offset 29 is made to engage the wall 30 of the hole .disposedin the tie plate 3|.

To prevent the over driving of the spike I place a shoulder 32 on the rear wall of the spike hole of the tie plate.

Since the head of the spike is not driven home to cause the head to engage the top of the base of the tie plate, the head of the spike is made much smaller than the head of a conventional spike as is illustrated in Figs. 1 to 4 inclusive.

and described is admirably adapted to fulfill the objects primarily stated, it isto be understood that it is not intended to confine the invention to the embodiment herein shown and described, as it is susceptible of embodiment in various forms, all coming within the scope of spikes that are to be used.

the claims which follow;

What -I claim is: 1. A railway said spike being pointed upon one of its ends and the body of said spike having a twist disposed therein.

2. A new article of manufacture made of 15 spring material and said article being pointed on one end and having a head disposed upon its other end and said head projecting outwardly from either edge of the article and said article having a plurality of offsets disposed upon the opposite broad face of the article of manufacture, and the body of the article being of greater width below the head and on the opposite side of the spike upon which the inset is disposed and the body of vthe spike, disposed below the inset, having a wind disposed therein, and the body of the to the u spike when the spike is driven in a railway tie.
