JOHN EDWIN KILBURN, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO HALE AND KILBURN COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION O1*1 DELAWARE.

CAR-SEAT SUPPORT.

Application filed August 11, 1915.

To all whom t may concern.'

Be it known that I, JOHN EDWIN Kur 1:n1zN,-a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Car-Seat Supports, of which the following is a specication.

My invention relates to supports for railway car-seats, in which the crossrails are tubular, and is an improvement upon the supporting structure disclosed in the application of Clarence L. Thompson, Serial No. 50,722, tiled September 15, 19415. It comprises a pedestal or pedestals supporting such rails, having curved bearing surfaces formed in the top flanges, the rails resting snugly therein and being secured by bolts extending through the same and the lower flanges of the pedestal arms. The rails are secured at their ends to the aisle and wall plates by means of a structure comprising stub-shafts inserted within the ends of the tubular rails, the stub-shafts comprising drawn, cast or turned, shells or cups mount ed with a forced fit within collars having flanges which may be secured, as by weld,- ing, to the inner surfaces of the end plates. Each shell is drawn, cast or turned, slightly larger than the opening in its collar, and the two being placed in a die, the shell is forced into place. The flanges of the collar are then welded to the aisle or wall plate, after which the projecting edge of the collar is machined to give a true bearing for the end of the tubular rail. The stubshafts of the aisle and wall plates are pushed into the ends of the tubular rails, until they contact the machined ends of the collars, when they may be simply secured, as by passing cotter pins through alined holes in the rails andl stubsshafts. By this construction the use of connecting rail bolts is obviated, with the troubles attendant on their subsequentl loosening in service. The rails being supported adjacent their outer ends by a pedestal designed to receive the same, in the manner described, and the aisle plate supported b y the ends of the rails, a simple, light and strong construction is presented, in which rigidity, perfect alinement and easy and secure assembly are the desirable results.

In, order that my invention may be more clearly understood, attention is hereby directed to the accompanying drawings, illus- Specification of Letters Patent.

Serial No. 44,896.

trating certain embodiments of my invention, and forming part of this application, in which Figure l represents anend elevation of a pedestal and aisle plate, Fig. Q is a vertical section on line 2-2 of Fig. l, Fig. 3 is a horizontal view, in plan and section, showing the connection of the tubular rails with the aisle plate, and the pedestal, Fig. 4 is an Venlarged horizontal section through the connection of the rail and aisle plate, Fig. 5 is a vertical section on line 5--5 of Fig. 4, Fig. G is a top plan view of a pedestal having a cover-plate, and Fig. 7 is a vertical section on line 7 7 of Fig. G.

Referring to -the drawings, the pedestal l supports the tubular cross-rails 2, which carry the aisle-end-plate 3 at their outer ends. The inner ends of the rails are preferably supported by a connection with a wallend-plate secured to the4 wall of the car, the plate and connection being identical with the aisle plate and connection about to be described. The plate 3 carries a curved tracl' -l of channel section, on which the rollers of a back-supporting standard may be mounted in well-known manner.

rlhe tubular rails Q are secured to the aislewplate 3 by means of the stub-shaft 5 and collar.l G, and to the wall-end plate (not shown) in the same manner. rllhe stubshaft 5 is drawn as a cup or shell having a closed end 7, and the collar 6 is formed with iianges 8, the shell being of a diameter slight-ly larger than the opening in the collar. The shell and collar are then placed in a die, and the shell forced into place in the collar as shown in the drawings, the shell having an outwardly-curved outer end 9, fitted within a similar curvature of the collar. The flanges 8 Of the collar are then welded to the inner surface of plate 3, after which the inner end surface l0 of the collar is machined to give a true plane bearing for the tubular rail 2. The procedure is of course the same for both stub-shafts and collars on both end-plates, the collars being accurately located on the plates in proper a-linement.

The stub-shafts of the wall-plate are then pushed into the ends of the tubular rails, until the rails abut the machined ends of lche collars, after which cotteifpins are slipped through holes in the stub-shafts and rails. The procedure is the same at the aisle end, the Cotter-pins being shown at 1l.

'IOS

'Ihe wall-plates may then be secured to the wall, and the rails secured adjacent to their outer ends on the pedestal 1, the aisle-plate being supported by the rails. By this construction the use of connecting rail bolts is eliminated, and a strong and simple con nection between the rails and end plates is provided.

The pedestal. 1 is preferably formed of pressed metal, with hollow arms 12 having top flanges 13 and lower flanges 14E. The top flanges are formed with downwardlycurved portions 15, which form bearing surfaces for the rails 2 and fit the latter snugly, insuring firm seats for t-he rails. A bolt 16 is passed through each rail and the upper and lower flanges of the pedestal arm, the nut being adjusted under the web or bottom flange of the pedestal arm. A thin plate of metal 17 may be placed over the top of the pedestal, as shown in Figs. 6 and 7, and formed over the flanges of the pedestal, as shown at 18', to entirely close the top of the pedestal.

, Having now described my invention, what I claim as new therein and desire to secure by Letters Patent is as follows 1. In a car-seat structure, the combination of an end plate, a collar having a peripheral flange secured to the inner surface of said plate, and an inwardly-curved bearing portion having a plane inner edge parallel to said surface, a cup-shaped stubshaft having an outwardly-curved edge portion secured within the bearing portion of said collar by a forced fit, a'tubular cross rail having its end slipped over said stubshaft into contact with said inner edge of said collar, and a pin extending through said 'rail and stub-shaft, substantially as set forth.

2. In a car-seat structure, the combinaAV tion of an end plate, a collar having a flange secured to the inner surface of said plate, and a bearing portion having a plane inner edge parallel to said surface, a stubshaft comprising a shell secured within said collar by a forced fit, and a tubular crossrail having` its` end slipped over said stubshaft into contact with said inner edge of. f

said collar, substantially as set forth.

This specification signed and witnessed this.7th day of August, A1915.
