DRAFT RIGGIN G.

Application filed November 13,1922. ASerial No. 600,660.

To all whom t may concern.'

' Be it known that I, DONALD S. Bannows, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certainy the purpose of transmitting to the car underframe bufling shocks to which the draft rigging mechanism is subjected under service conditions.

The principal featureof the invention, generally stated, is to provide a back stop casting having its end or buffing wall, the reinforcing portions therefor, and other webs and flanges arranged and disposed so as to economically distribute the metal and produce a casting Aof maximum strength value but comparatively light in weight.

Particularly stated, the invention has for an object the provision of a back stop casting having a reinforced front face or buffing wall formed by diverging webs or flanges arranged transversely of the casting, said webs uniting the sid walls and forming a hollow chamber or column portion between lthe spaced car sills to which latter the casting is connected.

The invention further involves'the production of a back stop casting in which the b-ufing wall is adequately braced at a plurality of spaced points by means of transversely disposed webs-which provide a triangular reinforcement adjacent the butiing.

wall.

Another `object of the invention is to provide acombined back stop and center filler casting which may beeffectively used with car underframes of different types, said casting being provided with a reinforced bufing wall and a plurality of webs or flanges advantageously arranged about the center thimble to receive and distribute without distortion the enormous shocks or blows to which the casting is subjected in actual service.

A further` object of the invention resides in the provision of a. back stop member adapted to be connected to the ear sills and arranged to cooperate with a movable element of the draft rigging, said back stop member being formed with maximum and readily accessible riveting areas at the most advantageous points for attaching the biick stop to the car underframe.

lVith these and other objects in view, the invention further consists in the combination and arrangement of the parts all as will hereinafter appear.

In the drawings illustrating the invention, the scope whereof is pointed out in the claims:

Figure 9. is a vertical longitudinal sectional view on the line 9 9 of Figure 8.

Figure l0 is a rear view in elevation of the modified form of back stop shown in Figures 8 and 9.

Referring to the drawings in which similar reference characters designate corresponding parts, the draft rigging l with which the back stop cooperates and spaced car sills 2 between and to which the back stop is secured, may be of any suit-ableeform. In the well known type of draft rigging, a portion of which is illustrated in the drawings, the rear end of the draft yoke B is the movable part -of the draft rigging which is adapted to communicate bufiing shocks to the back stop. It is to be understood that this special form of draft rigging is merely illustrative and is not disclosed for the purpose of limiting the invention to use in conjunction therewith.

My invention, as embodied in the form of back stop shown invFigures 1, 2 and 3, includes longitudinally extending side walls 4 each of which is provided with a plurality of rows of openings adapted to receive the connecting rivets 5, whereby the structure may be firmly connected to the sills 2 of the car underframe. llach of the side walls 4 is provided along its upper edge with relatively high portions or projections 6, said projecting portions being disposed forwardly and rearwardly of the center thimble 7 and arranged to provide an increased riveting area through which the uppermost row of rivets pass. A portion of each side wall is c ut away, as indicated at 8, between the projecting portions 6, thereby reducing the relative weight of the casting but effectively vmaintaining a sufficient rivet-ing area at the most advantageous points.

The side walls 4 are preferably united at their front ends by means of an upright transversely extending front end wall 9 adapted to form an abutment for the movable element or yoke 3 of the draft rigging. The front end wall 9 is also united to the side walls 4 by means of the diverging webs 10 transversely disposed immediately in the rear of said front end wall and arranged to yprovide a triangular reinforcement. One of the reinforcing webs 10 is united with the front wall relatively near the uppermost portion thereof, and the other of said webs is united with the front wall near the low! ermost portion thereof, both of said webs -being united to each other in spaced relation from said end wall, thereby forming a hollow column or chamber-ed portion extending transversely of the casting immediately adjacent the rear of the bufing or front end wall 9. The hollow column or chambered portion is preferably designed to extend transversely through the back sto casting, said hollow column or chambere portion opening directly. against the car vsills to which the side walls of the castingare connected. This type of hollow column reinforcement provides a particularly effective construction which can be easily cast.

United to the diverging webs 10 at their juncture in the rear of the front wall, is a longitudinally dispo-sed substantially horizontal web 11, said web 11 being designed to unite the side walls 4 and also connected to the center thimble 7. Openings 12 are providedin the horizontal web 11 preferably adjacent the side walls thereof, said openings permitting access to the base or floor web 13 and more particularly the rivets 14 which secure the casting to the bolster center plate. The openings 12 are preferably ar` ranged in vertical alinement with the portion oflthe floor web 13 through 'which the attaching rivets 1,4 extend. Bracing webs 15 serve to unite the side walls with the horizontal web 11, said bracing webs extending beneath the horizontal web and united with the floor web or base portion 13 of the casting transversely thereof, as best shown in Figure 3. A transversely disposed upright web 16 unites the center thimble on opposite sides thereof with the side wallsksaid web 16 being disposed at the inner edge of the horizontal web 11.

A longitudinallyl disposed centrally located upright web 17 extends rearwardly from the front end wall 9, said upright web being united to thevdiverging webs 10 and the horizontally disposed web 11. The vertical web 17 extends above and below the horizontal web'13, portions of said upright web being connected to the base portion or floor web 13, and other portions of said upright web being united to the center thimble.`

The casting may be further braced at its rear portion by longitudinally*extending ribs 18, said ribs being intersected by transversely disposed vertical ribs 19, both of said i/ ibs 13 and 19 being united to the side walls, as shown. The ribs 19 project beneath the horizontal ribs 18 and are united with the fioor web 13 of the casting transversely thereof, forming in effect the rear wall of said casting. A rear bracing rib 20 may be provided longitudinally of the casting, said bracing rib uniting the base portion or floor web of the casting andthe center thimble.

ln Figures 4 to 1() inclusive, I have shown two modifications of myy invention adapted for use with car underframes of. different types. These are but some of the various adaptations of my present invention which in the forms shown herein involve a casting composed of spaced side walls, a rear wall, and a front end or buffing web suitably braced or reinforced to resist t-e heavy strains incident to service conditions.

The form of back stop casting shown in Figures 4 to 7,inclusive, includes side walls 21 united at their forward ends by a transversely disposed upright web 22, which web forms the bufling abutment of the casting. Diverging rearwardly from the buffing wall 22 are bracing webs 23, said webs being transversely arran ed adjacent the rear face of said bufling' wal and united in spaced relation therefrom to form a hollow column reinforcement of triangular contour. A longitudinally extending horizontal web 24 is united with the diverging webs 23 at their points of juncture, the lowermost of said webs 23 being united with the horizontal web slightly in the rear of the junction of the uppermost web 23 with'said horizontal Web 24. This relatively offset junction of the respective diverging webs 23 and the forward end of the horizontal yveb 24 is clearly shown in Figure 5. The horizontal web extends longitudinally through the casting to the rear wall 25 thereof and is preferably inclined upwardly toward the longitudinal center of the casting, as shown in Figures 6 `and 7. A vertical longitudinally extending web 264 intersects the horizontal web 24 and also is united with the respective diverging webs 23 and the front end wall 22. The lower edge of the vertical or upright web 26 is united with the base or floor web 27 of the casting.

The modification shown in Figures 8, 9 and l0 includes a casting formed with side walls 28 united at their forward ends by an upright bufling or front end wall 29. The front end wall is reinforced by transversely disposed divergent webs 30, said webs uniting the side walls and front walls, and also beingunited to each other at the rear of the front end wall to form the triangular reinforcement best shown in Figure 9. From the junction of the webs 30 extends a horizontal web 31, said web serving to unite the bracing webs 30 with the rear wall 32, and also transversely connecting the side walls of the casting. A central longitudinally extending upright web 33 intersects the horizontal web 31 and serves to unite the front and rear walls of the casting, said vertical web also being united to the diverging webs 30. Other bracing webs 34 may be provided between the rear end of the casing and the side walls, and still other webs 35 may be interposed between the side walls and horizontal web 31.

It will be perceived from my present invention that the metal is disposed in sucha manner as to give maximum strength value to the severalj parts and also provide ample and readily accessible space for conveniently inserting and driving the rivets connecting the casting to the spaced car sills.
