RAILWAY-BUMPER.

Specification of Letters Patent.

Patented Jan. 29, 1907.

A plicatlan filed June 22,1906. Serial No. 322,817.

To all whom it may col Learn:

Be it known that I, JOHN M. SooTT, a citizen of the United States, residing at Racine, in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in Railway-Bumpers, of which the following is a specification, reference be-. ing had to the accompanying drawings, forming a part thereof.

This invention relates to devices for stopping cars at the ends of switches or railwaytracks. Its main object is to produce a simple, strong, and effective device of this class which can be easily applied to and removed from a railway-track without cutting, drilling, or bending the rails.

It consists in certain novel features of con struction and in the peculiar arrangement and combination of parts, as hereinafter particularly described, and defined in the claims.

In the accompanying drawings like letters designate the same parts in the several figures.

Figure 1 is a perspective view of a railwaybumper embodying the present invention as applied to the rails of a track. Fig. 2 is an enlarged vertical longitudinal section of the upper part of one of the standards with the associated buffer-block shown in side elevation, and Fig. 3 is an enlarged view of one of the toothed wedges for securing the standards on the track-rails.

The bumper, which is preferably made entirely of malleable iron or steel, comprises a pair of similar standards or legs a, which are secured on the track-rails by wedges l) and are formed with spring cases or sockets 0 above and parallel with the rails, bufferblocks (1, movably held in and protruding from said sockets, spiral springs e, inserted in said sockets behind said blocks, and a tie-rodor cross-brace f, connecting thestandards above the track-rails.

The bases or lower ends of the standards are extended lengthwise of the rails and are recessed to 'fit over and engage with the same. They are alsoformed lengthwise of and next to the rails with tapering recesses in which the toothed wedges b are fitted and adapted to be driven, so as to firmly secure Wedges are employed for securing and holding each standard in place on a rail, one on each side of the rail-web in front and one on top of the rail at the rear. The teeth of the wedges are presented to the rails and are so Preferably three.

formed that their bite or grip thereon will be tightened by the impart of, cars against the bum er.

The buffer-blocks d, which for the sake of lightness are preferably made hollow, are formed with rearwardly-extending parallel stems g, around which the s rings 6 are placed, the lower stem on each block projecting through an opening in the back side of the standard, and thus aiding to guide and hold said block in place. The front or outer faces of these blocks, which are adapted to engage with the wheel-treads, as indicated by a dotted line on Fig. 2, or with outside brakebeams of cars which are run against the bumper, are held normally by 'the springs e projected to the full limit of their forward movement from the standards, as shown in the drawing, the advance or outward movement of the blocks being limited by bolts h, connecting them with the standards, as shown in Fig. 2. I

The tie-rod or cross-brace f is threaded at the ends and provided with nuts both inside and outside of the standards a, through which it passes, thereby securely holding them and the blocks d at the proper distance apart.

To apply the bumper to a track, the spikes holding the rails to which it is. to be fastened are withdrawn, and the standards are then slipped over the ends of the rails and secured in place thereon by driving the wedges b into the tapering recesses provided therefor in the bases of the standards. The tie rod or brace f is inserted through the holes therefor in the adjusted and tightened thereon. The trackrails are again spiked to the ties, and the device is ready for use.

The bumper is removed from a track by withdrawing the spikes from the rails, driving the wedges 5 out of the standards, and then slipping the standards off at the free ends of the rails.

Various changes in details of construction and arrangement of parts may be made without departing from the principle and intended scope of the invention.

I claim 1. In a railway-bumper the combination of a pair of similar standards having bases extended lengthwise of and adapted to be secured to the track-rails, buffer-blocks movably mounted in said standards above the rails in position to engage the wheel-treads upper parts of the standards, and the nuts are rails, buffer-blocks fitted in said sockets,

springs interposed between said blocks and I the rear ends of said sockets, and a crossbrace for connecting said standards with each other above the rails, substantially as described.

3'. In a railway-bumper the combination of a pair of standards having bases extended.

lengthwise of the track-rails and recessed to fit over and engage with the same and sock ets above and parallel with the rails, means for securing said standards on the rails, buflenblocks fitted and movable in said blocks and the rear ends of the sockets, and a cross-brace connectingsaid standards above therails, substantially as described.

4. In arailway-buil er the combination of standards having extended bases recessed to fit over and engage. with the track-rails and sockets above and parallel with the rails,

wedges fitted in tapering recesses in said 0 standards neXt to and lengthwise of the rails and adapted to be driven into place to secure the standards on the rails, butter-blocks movably held in said sockets and protruding from said standards, and springs interposed between said blocks and the rear ends of said sockets, substantially as described.

5. I11 :1 railway-bumper the combination of similar standards adapted to be secured to the track-rails and formed with sockets above and parallel with the rails, movable butlerblocks fitted in and projecting from the open front ends of said sockets and each provided with rearwardly projecting stems, spiral springs surrounding said stems within the 5 sockets and bearing at their front ends against the backs of said blocks and at their other ends against the rear ends of the sock ets, and means for limiting the forward movement of said blocks, substantially as sockets,spr1ngs interposed between said described.

In witness whereof I hereto atIiX my signature in presence of two witnesses.

JOHN M. SCOTT.
