METALLIC RAIL-FASTENING.

improved means for securing rails in position.

upon metallic ties.

Another ob 'ect is to provide a securing means in which, after the spikes have been driven home they will be securely locked against accidental removal.

A further object is to provide a construction in which the expansion and contraction of the several parts will not detract from the utility of or have any material detrimental effect upon the device.

With these and other objects in View, the present invention consists in the combination and arrangement of parts, which will be ticularly pointed out in the appended claims, it being understood that changes in the specific structure shown and described may be made within the scope of the claims without departing from the spirit of the invention.

In the drawings forming a part of this specification and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a central longitudinal section through a metallic railroad tie, the rails secured in position thereon, one of the blocks being shown in section.

on the line 22, of Fig. 1. Fig. 3 is a longi tudinal section throu h a portion of the tie and one of the blocks illustrating a modification.

Referring to the drawings, 1 indicates a hollow metallic tie and 2 the rails superposed thereon. Centrally located beneath each of the rails, within the tie, are the blocks 3. These blocks are provided with the apertures 4, adjacent to their ends, which diverge downwardly to the middle portion of the blocks. From this point the apertures converge toward the bottom of the blocks. It will thus be seen that the apertures 4 are angularly extended from the approximate longitudinal center of the blocks. .A transverse opening is formed in the ends of the Specification of Letters Patent.

blocks at the angle in the apertures 4:, the purpose of which will be later described. The top of the tie is also provided with apertures 4 which are in alinernent with those of the blocks. Each of the blocks is formed with thelongitudinal extension 5, through which are adapted to extend the bolts 6, secured therein by means of the nuts 7, thus firmly securing the blocks in position. The blocks are preferably formed of hardened steel, and spikes-80f comparatively softer material are driven into the apertures formed. therein. The spikes will of course bend to conform to the angle of the apertures, and it will be readily seen that after they have once been driven home, to remove them wou'ldbe extremely difficult, if not impossible. After the spikes have been inserted into the apertures and the heads of the same are firmly engaged with the flanges of the rail, the transverse openings will be left in the block at the angle of the apertures 4, at the inner sides thereof, or toward the longitudinal centers of the rails. Into these openings are driven the pins 9 as an additional means of security for the spikes. Thus should there be any loosening of the spikes owing to the expansion or contraction of the metal, the rails will still be securely held in the aperture by means of the pins 9.

In Fig. 3 I have shown a slight modification in which the securing pin 9 is located at the outside edge of the spike slightly above the angle in the apertures 4. This will accomplish the same result and be equally as efficacious in the event of any loosening of the parts as in the construction above described.

From the foregoing it will be seen that I have providedfa metallic rail fastening which will securely hold the rail to the tie and overcome any tendency of the spike to work out of the apertures 4.

My invention is very simple and inexpensive in construction, and highly efiicient and durable in operation, and Having thus described my said invention, what I claim as new and desire to secure by United States Letters Patent is:

1. A metallic rail fastening comprising a hollow tie, blocks located in said tie at either end thereof, beneath the rail, longitudinal extensions at the upper ends of said blocks, apertures formed in said blocks and inwardly diverging from the longitudinal center thereof, openings in said tie in alinemei'it with said apertures, and spikes adapted to be driven into said apertures substantially as and for the purpose set forth.

2. A metallic rail fastening comprising a hollow metal tie, metal blocks located in said tie at either end thereof beneath the rail, longitudinal extensions at the upper ends of said blocks, bolts extending through said ties and secured in said extensions, apertures formed in said blocks and diverging at an obtuse angle from the longitudinal center thereof, openings in said tie in alinement with said apertures, and spikes formed of a comparatively softer material than that of said block and adapted to be driven into said apertures and. conform thereto, substantially as and for the purpose set forth.

3. A metallic rail fastening comprising a hollow metal tie, blocks located in said tie at either end thereof beneath the rails, longitudinal extensions at the upper ends of said blocks, means for securing said blocks to said tie, apertures inwardly diverging from the longitudinal center of said blocks, openings insaid tie in alinement with said apertures, I spikes of a comparatively softer material than said blocks adapted to be driven into said apertures and conform thereto and transverse pins in said blocks frictionally engaging with said spikes substantially as and for the purpose set forth.

4. A metallic rail fastening comprising a hollow metal tie, blocks located in said tie at either end thereof beneath the rails, means for securing said blocks to said tie, apertures in said blocks and angularly extending from the longitudinal center thereof, transverse openings formed in said blocks and communicating with said apertures, openings in said with the inner edge of said. spikes at the angle thereof substantially as and for the purpose set forth.

In testimony whereof I ailix. my signature, in presence of two witnesses.
