RAILWAY-BUMPER.

$PECIFIGATION formingrpart of Letters Patent N 0. 676,630, dated. June 18, 1901.

Application filed May 28, 1900- To all whom it may concern.-

Be it known that I, ALVIN C. MCCORD, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvementin Railway-Bumpers, (Case No.

6,) of which the followingis'a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specificatiom My invention relates to that class of apparatus which is usually placed at the end of railroad-tracks and which is adapted to arrest the progress of a train moving toward the end of the said railroad-track.

More particularly, my invention relates to railroad bumping-posts, and has for an object the provision of a bumping-post of this class which shall be simple and durable and which may be easily constructed and put in place.

Heretofore it has generally been necessary in erecting railroad bumping-posts upon the end of railroad-tracks to provide therefor separate and independent foundations.

It is also an object of my present invention" so to construct a railroad bumping-post that the same may be placed at the end of a liner of track without providingtherefor an extra foundation. 1

A further-feature of my invention consists in the provision of a railroad. bumping-post in which the stress caused thereon by the moving train -shall be equalized and distributed in an efficient manner without causing an undue depreciation of the railroad bumping-post.

' In the preferred embodiment of my invention I preferably employ two rails of the railroad-track to serve as stops, as well as to di-'- vert the stress transmitted thereto from the bumping-post, the said rails being converged at the ends thereof and suitably fastened to supporting rods or standards which slant upwardly and are in engagement preferably with the bumping-post. vI'preferably employ in the preferred embodiment of myinjvention asuitable stifieningrod,preferably extendinglengthwise of the track, which rod or standard is adapted to receive thrust occasioned by the bumper-post and distribute the same along the track. I provide suitable means for holding the said'stilfening-railin position Q'Th'e said. stiffening-rail 13 .iSz-united to the v "bumper 4. preferably through the agency of a.

along the track, so thatthe same'will not be come disarranged. I

Serial No. 18,284. (No model.)

Further objects of my invention willbe ap- 5 5 parent from the construction which I will now describe, in connection with the accompanying drawings, illustrating one embodi-I ment thereof, in which- 7 Figure 1 is a side elevation of a bumpingpost constructed in accordance with my invention. Fig. 2 is a top view thereof. Fig. 3 is a rear elevation of the same. Fig. 4 is an enlarged view of the bumperwhich I pref erably employ.

Like parts are indicated by like characters of reference throughout the different views. M Referring now to the drawings,I have shown a pair of rails l 1 of a railroad-track, suitably I supported upon ties 2 2. I preferably bend the rails 11 at theend of the track, so that they converge some distance toward the center thereof, from which point they again preferably extend in sections 3 '3, parallel to-the center of the track, the rail-centers, however, being close together. In order to arrest the movement of the train, I employabumper 4, consisting, preferably, of a steel plate 5, suit: ably fastened to the mainsupport 6', an intermediate piece of wood 7 being preferably employed to deaden the shock created by the impact of themoving train. The bumper is suitably fastened to'the sections 3 3 of, the main track, vpreferably through the agency of rails 8 8, the said rails entering recesses 8 9 9, provided in the bumper 4. The rails 8 8 are fastened to the-parallel sections 3 3 of the-main rails 1 1 by means'of washers 10' 10,.placed between the same, and bolts 11 1l,1passing'therethrough. The rails 8 890 are preferably horizontal for a short distance in order to register with the parallel sections 3 '3 of the main track 1, the said rails 8 8 then preferably extending upward slantingly toward the, bumper '4. The-steeltplate 5 is preferably held in place through the agency of vbolts 12 12. In order to distribute the shock along the road-bed when amoving train strikes the bumper 4, I employ-a. stiifening rod 13, consisting,'preferably, of a rail and rooextending, preferably, below-ties 2 2 in a line substantiallyparallel to the direction of the trackif" This stifi'ening' rod or lever engages the main-track rails in this instance through theagenoy of; intervening cross-ties, so that force may-be exerted upwardly up'onthe track.

tension rod or member 14, extending about the said ,rail and engaging a slotted guide a moving train, the said rod extending, preferably, from the ends of the rail-sections 3 3 to a point forward of the tensionrods 14,wl1ich is best suited to the size and weight of the rail or bar employed as a stiffening-bar. In one aspect of the case it may be considered that the standard is comprised of the inclined rails 8 8 and the tension niernber14, connecting the rails 8 8 with the stiffening-bar 13.

In order to prevent a sidewise motion of the bumper 4 in either direction, I employ guy-rods 1.6 16, which are preferably fastened in suitable supports 17 17, the said supports being fastened to the rail-section 1 through the agency of bolts- 18 18.- The guy-rods 16 16 preferably extend through slots 19 19., provided in the bumper 4, the said guy-rods passing through a plate 20, placed upon' the top of the said bumper, the nuts 21 21 serving to hold the guy-rods in position with respect to the said bumper. Any suitable means maybe employed, however, for preventing sideward movement of the bumper. The guy-rods 16 preferably have no other function. I I

Referring now particularly to Fig. 1, I have shown the direction of the force applied to the bumper 4 by a moving train, as indicated by the arrow at. This force a will be transmitted toward the roa'd-bed'of the track bythe rails 8 8. As the rails 8 8 are, however, fastened to the parallel sections 3 3 of the main track 1, no longitudinal movementlengthwise of the track takes place and the thrust oceasioned by the moving train is converted into a downward thrust, as indicated by, the arrow I). This downward thrust is counteracted by the stiEening-rail 13, acting as a lever, the said rail exerting an upw'm'd thrust against the railroad-track, as 'shown by the arrows c c. The said rail 13 being pivoted or secured in place by meansof the tension-rod 14, a sufficien tleverage is obtained, providing-a rail of suitable size is used to counteract the "thrust occasioned by the train without bending thesaid rail or causing its dis: figuration; The lever 13 is preferably elongatedsirfliciently to extend a suificient distaneetbeneath the car tosecure the further resistance of the weight thereof to further counteract the upward thrust, the free forwarde'nd ot the lever being thus most effective as theweight of the ear or locomotive cooperates therewith to secure the desired re'- sistance. 1am thus enabled to dispense with expensive foundations,- as the weight of the vehicle on the ties will thoroughly and effect; ively eoeperate with the lever to secure the desired oppesition.
