' Application led February 7, 1910. Serial No. 542,518.

gripping and holding the base iange of al rail m position upon a tie, whereby the rail cannot become accidentally displaced byv eX pension or contraction or by the action of rolling stock passing over the same.

Furthermore, lthe invention aims'to provide a spike of simple construction that can be easily placed in position and withdrawn. With this understanding of the aim of my invention, reference will now be had to the drawing forming a part 'ofthis specication, wherein Figure 1 is a perspective View of a spike constructed in accordance with my invention, and lFig. 2 is a side elevation of the same, partly broken away, illustrating the spike mounted in a tie to retain a rail thereon.

In the accompanying drawing the reference numeral l denotes a shank rectangular in cross section and having the lower end thereof pointed by tapering or providing opposite sides of the shank with beveled surfaces 2, thus forming a point similar to the present type of spike. rllhe upper end of the shank 1 is enlarged to form a hea'd3 and the formation of said head provides overhang ing shoulders or ledgesA corresponding in width to said shank. `The shoulders or ledges are adapted to limit the movement of the spike into a tie 5, besides providing gripping surfaces for a suitable instrument,` as a crowbar, 4when the spike is not-completely driven into the tie and when itis desired to withdraw the same from the tie. v 4

The head 3 upon the outer side of the spike projects s uciently to lform an outwardly entendi flange 6, and this dan e is adapted'to facilitate the withdrawal o the spike,when the shoulders l engage the-upper surface ofthe tie. The head 3 is also formed"` with an inwardlyuprojecting Harige 7 adapts ed to overhang the base Bange 8 of a rail 9,

said-dange corresponding in width to the head 3. and having a: depending rib l@ corre spondingin width to the dange i and the head 3. The rib l0 is of a depth when combined with the deth 'ci the Harige 7, to equal the depth o the head 3, from the shoulder 4 to the 'u per edge or top surface of the head 3. T 1s depending ribl() is adapted to enter a longitudinal groove l1 provided therefor inthe upper surfaces of the base -tlanges 8 of the rail 9, said cove being located adjacent to the outer edgges of the base danges and adapted to extend from one end of said rail to the opposite end` thereof, whereby the rail can be easily secured in position by my improved spikes, irrespective of the location of the ties 5 relativel to said rail.

With the base anges 8 of the rail secured upon a tie by my im roved spikes, lateral as well asl vertical. dis Ilacement of the rail is prevented by theY ase anges contactin with the shank of the spike, the danges overhanging the base flanges, and the 'ribs t 10. of the s ikes engaging inthe grooves 1l provided t erefor.

Having now described my invention what I claim as new, is 4 The combination with a rail having the base flanges thereof provided with'longitudinal ooves adjacent tothe outer edges of said dnges, of a spike, each spike comprising a shank having the lower end thereof pointed, ahead carried by 'theupper end of said shank and providing shoulders at the sides of said shank adapted to limit the inward movement of the spike relativelyto a tie, anv outwardly rejecting flange carried by said head andp grippin surface for an instrument ada ted to wlth raw said spike, an inwardly projecting flange carried y the head `of said spike and ada ted to overhan the base flange of said ra' and a 'depen ing rib carried by said Hangs and ada ted to engage in the groove o the base ange oi' said rail, said rib corresponding width to said ange adapted to provide a.

and of a depth when combined with thef depth of said ange to correspond tothe depth of said head, substantially as described.

In testimony whereof l ax my signature in the presence of two witnesses.
