w. A. BEAUCHAMP TRACK BRACKET Original Filed July 20, 1951 Patented Nov. 10, 1936 UNITED STATES PATENT OFFICE TRACK BRACKET of Ohio Original application July 20, 1931, Serial No. 551,855, now Patent No. 1,963,821, dated June Divided and this application October 28, 1933, Serial No. 695,557

7 Claims.

This invention relates to track brackets and concerns itself primarily with brackets for securing tracks for sliding doors of railway house cars in position without the use of rivets or the like.

A considerable part of the cost of application of car fixtures for sliding car doors may be attributed to the expense involved in supporting the tracks for said doors upon the car underframe. For such support brackets are usually employed, these brackets being riveted to the side sills of the car underframe and the track being riveted to the brackets. The expense entailed in the operation of riveting the track to the brackets is material. The employment of supporting brackets which obviate this operation appears highly desirable and conducive of economies which measurably reduce the cost of car construction.

It is an object of this invention to provide track supporting brackets which eliminate in a large measure the necessity of riveting said track to the brackets and the expense incident thereto.

A further object is the provision of track brackets which, while obviating riveting of the track thereto, provide secure support for said track.

An object is the provision of track supporting brackets with which a track may be readily and simply assembled.

It is an object to provide track supporting brackets in which the assembly with the track is completed by the riveting operation which secures the brackets to the side sills.'

Other objects of this invention will become apparent as the description thereof proceeds.

In the drawing forming part of this specification:

Figure 1 is a partial elevation of a house car showing one embodiment of the invention applied thereto;

Figure 2 is a vertical section taken on line 2--2 of Figure 1, the lower portion of a door and a supporting hanger being shown in dot and dash lines to indicate the relationship thereof with the track;

Figure 3 is a front elevational detail of a complementary arm member as shown in Figure 2 of the drawing;

Figure 4 is a front elevational detail of the other complementary member of the track bracket illustrated in Figure 2;

Figure 5 is a vertical section similar to Figure 2 illustrating a modification of the invention;

Figure 6 is an elevational view similar toFigure 3 illustrating the complementary arm member of the bracket shown in Figure 5; and

Figure 7 is a View similar to Figure 4 illustrating the other complementary member of the track bracket shown in Figure 5.

Referring to the embodiment of the invention illustrated in Figures 1 t0 4, inclusive of the drawing the numeral I 0 designates a-fragmentary portion of a house car which embodies a side sill I I. The track I3 is adapted to be supported from the side sill by means of a plurality of track brackets I4. The track is utilized to support a sliding door, shown partially in dot and dash lines in Figure 2 of the drawing, customarily employed upon each of the sides of a house car.

In this embodiment of the invention each of the track supporting brackets I4 comprises an outwardly disposed member I5 and an inwardly disposed complementary arm member IS. The outer member I5 is provided with a vertical flange I! by means of which said member may be attached to the side sill II by a plurality of rivets I8. The outer member I5 is provided, additionally, with an upwardly extending arm I9 disposed in outwardly ofiset relationship with respect to the attaching flange IT. The upwardly extending arm I9 adjacent the horizontally offset portion 20 of the member I5 is provided with an inwardly extending lug 2|, the underface of which as clearly indicated in Figure 2 of the drawing, is downwardly and outwardly inclined. The upper extremity of the arm I9 is turned outwardly so as to provide a supporting flange 22, for a purpose which will hereinafter appear.

The member I6 is complementary with the outwardly disposed member I5 and cooperates therewith in the formation of the track supporting bracket. Said complementary arm member I6 is recessed as indicated at 23 so as to provide a ledge 24 and a downwardly and outwardly inclined projection 25.

The track I3, which is adapted to be supported by the track brackets I4, embodies a substantially vertical flange 26 from one extremity of which there projects a substantially horizontal flange 21. A substantially horizontal flange 28 projects from the other extremity of said vertical flange and constitutes the tread of the door supporting track I3. This tread is provided with a downwardly extending depending flange 29 which, as clearly appears from Figure 2 of the drawing, is adapted to coact with the door hangers in order to prevent disengagement of the lower portion of the door from the track.

In supporting the track l3 by a plurality of the track brackets illustrated in Figures 1 to 4, inelusive, the outwardly disposed member 15 and the complementary arm member l6 are assembled with the track so that the latter is disposed with the vertical flange 26 thereof and the horizontally extending flange 21 positioned within the vertically and laterally extending recesses 30 provided by the complementary engagement between the members l5 and I6. Additionally, the tread 28 of the track is disposed upon the outwardly extending flange 22 of the arm 19 whereby said flange acts as an abutment or support for the tread of the track. It will be observed from Figure 2 of the drawing that the complementary arm member IS in the application of the track and track brackets to the side sill l I is positioned in engagement with said side sill. Furthermore, the projection 25 provided on the complementary arm member I6 is disposed with its downwardly and outwardly inclined face engaging under the correspondingly inclined lug 21 provided on the arm I 9. When these parts are applied to the sill and the rivets l8 driven through the attaching flanges l1 and the side sill it will be apparent that the outer member l5 of each of the supporting brackets will be forced into engagement with the sill and that, as a consequence of the engaging inclined faces provided on the complementary arm member l6 and on the arm l9, said complementary arm member [6 will be forced tightly into engagement with the side sill and will have imparted thereto a downward movement. As a result of this movement of the complementary arm member the ledge 24 will exert a downward pressure upon the track 13 through its engagement with the horizontal flange 21, while the outer corner 3| of each of the complementary arm members will engage the vertical flange 23 of the track 13 and thus insure firm seating of the tread 23 of the track upon the tread supporting flange 22 provided on the arm l9.

A modification of the invention is illustrated in Figures 5, 6 and 7 of the drawing. In this modification a complementary arm member 32 is utilized which, as clearly appears from Figure 6 of the drawing, is substantially inverted T-shaped in front elevation. oppositely extending flanges 33 and 34 provided at the lower extremity of the complementary arm member have downwardly and outwardly inclined upper faces as indicated at 35 and 36.

The complementary arm member 32 is adapted to coact with a member 31 to provide a track supporting bracket, the member 31 of which is disposed outwardly relative to the complementary arm member 32 in the operative position of said bracket. The outwardly disposed member 31 comprises a vertical attaching flange 38 and an outwardly offset arm 39, there being an offset 40 between these portions. Said offset portion 40 is recessed as indicated at 4| so as to provide flanges 42 and 43 so disposed that the recessed portion 4! is substantially of inverted T-shaped formation. Each of the flanges 42 and 43 has its lower face formed so as to provide downwardly and outwardly inclined portions 44 and 45.

In addition to the foregoing described elements the complementary arm member 32 is formed with a ledge 46 and the arm 39 of the outwardly disposed member 31 is provided with an outturned supporting flange 41.

In the application of the brackets of this modified form of the invention and the track I3 to the side sill l I the vertical flange 26 and the horizontal flange 21 provided on the track 13 are disposed in the downwardly and laterally extending recess 48 provided between the outwardly disposed member 31 and the complementary arm member 32 of each of the track supporting brackets. The portion of each of the complementary arm members 32 lying below the ledge 46 extends into the recess 4! provided in the outwardly extending member 31 so that the flanges 3-3 and 34 of said complementary arm member lie below and in engagement with the flanges 42 and 43 provided on said outwardly disposed member. In this relationship the outwardly and downwardly inclined faces 35 and 36 formed on the complementary arm member engage the correspondingly formed faces 44 and on the underside of the flanges 42 and 43. These parts are secured to the side sill I by means of a plurality of rivets 49, the complementary arm members being positioned in engagement with the side sill. As the rivets 49 are driven through the attaching flanges 38 and the side sill the complementary arm members, because of their engagement with the side sill and because of the coaction of the downwardly and outwardly inclined faces provided on said complementary arm members and said outwardly disposed members 31, will be forced downwardly. As a consequence of this movement of the complementary arm members, the ledges 46 provided thereon will engage and exert a downward force upon the horizontally extending flange 21 of the track 13 while the outer corner 50 of each of the complementary arm members will engage the vertical flange 26 of the track so as to insure firm engagement of the tread 28 upon the horizontal flange 41 and tight binding engagement of the track between the complementary members of each of the track supporting brackets. It will be apparent, therefore, that in each of the embodiments of the invention the track will be securely held against movement relative to the side sill by means of the track supporting brackets of the invention.

This application is a division of application Serial No; 551,855, filed July 20, 1931, which has become Patent 1,963,821 granted June 19, 1934.

It will be apparent that numerous changes and modifications in the details of the invention will be clear to those skilled in the art. It is intended, therefore, that all such modifications and changes be comprehended within this invention, which is to be limited only by the scope of the claims appended hereto.
