a eitiZeu of the United States. rest-ting in the horough of Brooklyn. eounty of Kings.

and State of New York. have invented eertain new and us ful Improvements in (or tonstruetion. of whieh the following is a full and elear speeitieation.

This invention relates to ears. and has for is primary ohjeet to provide an improved eon truetion omlrination and arrangement of parts with a view to rendering a ear more simply and eeonomieally etmstru ted. whieh ean be operated a smaller expenditure of power and whieh will involve less wear and tear on both the rolling Stm'k and traek or road bed.

one of th ohjeets of the present invention is to provide an improved ear construction emhodying sheets or plates whieh eon stitnte suhstantial portions of the side walls of the ear. and whieh dates are suitably reinforeed and supported to adapt them to act. as laterally spat-ed trusses vertieally arranged to earry substantially the entire weight of the ear hotly.

Toward the attainment of thisohieet my invention eontemplates the provision of suitahle means whereby said plates or sheets are seeu'red direetly to the ends of ear hotly holsters whieh are swiveled upon the truck holsters at opposite ends of the ear.

Other and further ohjeets will appear in the speeitieation and he pointed out in the appended elaims. referenee heing had to the eeonnmnying drawing representing one entlaaliinent of my invention. and in whieh.

Referring more partieularly to the draw ings. my invention is exemplified therein in its adaptation to a traetion ear of the general type shown in Figs. 1 and which embodies a eentrally disposed platform 1 conneeted by inclines Q with the level portions 3 over the front and rear trucks of said car. The platform 1 is depressed below the lower ends of the inelines 2 so that passenge s entering from either side are required to mount a single step on to the platform 1 and thenee a single step onto the lnelines '2.

lleferring more particularly to Fig.3. the truek t at eaeh end of the ear is provided Swiveled upon the truek l a hody holster whieh in the present einlzodiinent eomprises a pair of spat-ed beams t3. whieh are rigidly eouueeted by a top plate 7 and hottotu plate For this purpose, said heatus t1 are preferahly made of ehan-' ueled eross eetion and the plates 7 and 8 are riveted to the outwardly turned flanges 11 of said heant ti. on eaeh end of the hol ter is a supporting hraeket provided with an inwardly turue-l hox like projeetion whieh i seeured hy rivets it to the spat-ed heams or plates U (see Figs. 3. l and 5). As seen hy these tignres. said hraeket is also provided with welis or |)l7ll't. ltl. whieh rest upon the upper edges of the heams or plates t' adjaeent th eXtremities of the top plate 7.

In order to prtnide latera ly spared flllssts whieh upport suhstantialh tit) the entire weight of the car body, the sheet girders or plates which form substantial portions of the side walls of a car, are arranged in the form of end panels 14 to the inner ends of which are rigidly secured in any suitable manner, spaced door posts 15, which are rigidly united above by a cross beam 16 and below by means of a sill beam 17, which cooperates with an angle bar 18 extending across the door frame and throughout the lengths of the plates or girders 14, 14 and conforming to the lower edges thereof. The upper edges of said plates or girders are reinforced and stiffened by means of side bars 1%). Detached detail views of these several parts are represented. in Figs. 7 to 11, inclusive. In the preferred embodiment of my invention reference being had more especially to Figs. 3 and 9, the laterally spaced trusses are supported directly from the trucks in the manner already described, to adapt them to support the entire weight of the car body, which is carried thereby. Each of the panels 14 increases in depth toward the door frame, the broadest portion of the panel being rigidly bolted or riveted to the post of said door frame in the manner shown in Fig. 12. At regularly spaced intervals along each panel 14 cleats or stiffening bars 20 are riv led to the panel 14 and serve to hold said panel from buckling horizontally. The straps or cleats 20 are preferably extended upwardly to form the posts or uprights for supporting the roof 21, shfiwn in dotted ines.

now to Figs. 13, 14. and 15, each of the panels 14. is bordered above by the buckled plate 19, the inwardly deflected upper edge of said plate being adapted to receive the inclined plate 22, secured to alongitudinal beam 23, which constitutes the jamb of the side windows of the car. As shown best in F 14 and 15, the cleats or uprights 20 are provided with laterally projecting flanges 24, whereby, they are adapted to be riveted to the panel 14. The flange 24 is deflected at 25 to form a recess adjacent the bottom of cleat 20, for the reception of the vertical flange of the angle side bar 18. The jamb or sill beam 23 is recessed in the form shown in Fig. 14 to receive the upper edge of an inner plate 26, the lower edge of said plate 26 being rigidly connected by a Z-bar 27 with an angle bar 28, which is rigidly mounted on the cleats or posts 20, and serves to support the transverse beams 29, Which carry the floor 30 of the car. As indicated in Fig. 15, a door sill plate is provided by the horizontal branch of the reinforcing tension bar 17, which extends across the door frame and is rigidly secured to the panels 14- on either side thereof in any suitable nianner. Mounted upon said bar 17, is a channel bar 32, which provides a guiding groove 3-"), for rollers (not shown on the Referring drawings) carried by the lower edges of the doors 31. As details of construction in the present embodiment, the cross beam 16, which rigidly unites the uprights of the door frame as shown in Fig. 17 is buckled outwardly at to form a strengthening rib. The upper edge of the cross beam 16, is rigidly secured to an angle beam 36, (see Fig. 13), which is carried on the upper ends of the posts or cleats 20. the roof 21 of the car being supported on each side by an inwardly deflected plate 37. which is rigid with, or forms a part of the cross-beam 16. Means for reinforcing the uprights 15 of the door frame, are shown in Fig. 16, in which said post 15 is shown to be constructed of a plate having its ends folded over and rigidly secured to itself to form hollow columns 38 and 39.

Referring now to Figs. 1 and 5 it will be seen that according to the preferred embodi ment of my invention shown on the accompanying drawings, the entire load transmitted to the transverse body bolsters by means of the brackets on the ends of said bolsters is carried on either side at each end by a plurality of rivets 40 which are ar ranged in series along the lower edge of the panel plates 14. The rivets 14 in effect act to stiffen the connection between the panel 14 and the bracket 12, 13.

The advantages of my improved car construction wilT now b readily understood and briefly explained are due to the following features. By the arrangement of laterally spaced trusses constructed of relatively thin vertically disposed plates which increases in depth from the ends toward the centrally disposed door frame, it becomes unnecessary to embody the usual heavy, cumbersome and expensive beams and girders which constitute the main under frame of the car. In order to make available the full strength of the panels 14 when disposed on edge, thev reinforcing side bars 18 and 19. in conjunction with the cleats or posts 11, serve to pre vent buckling in any direction and in effect form a substantially rigid truss which practically constitutes the closed in port ion of the sides of the car body. brief inspection of the drawings will show that the total weight of the car is transmitted and supported by these longitudinal trusses comprising the reinforced panels 14 at either end connected by the centrally disposed door frame. Incidentally said door frame forms a transverse enlargement of the truss at the point of greatest moment. This construction is comparatively light, strong, economical to manufacture, and consumes relatively small power in operation and is relatively easy upon the track roadbed. At opposite ends of the car the laterally spaced trusses are supported directly from the body bolsters which are swiveled upon the truck bolsters.

It will, of course, be understood that various modifications in the construction and arrangement of parts can be made without departing from the broad spirit of my invention.
