PLATFORM m RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 645,649, dated March 20, 1900.

Application filed August 8, 1898.

To all whom it may concern.- E

Beit known that I, WILLARD F. RICHARDS, acitizenof the United States, residing at Buffalo,'in the county of Erie and State of New York, have invented a new and useful Improvement in Patforms for Railway-Cars, of which the following is a specification.

This invention relates to railway-cars in which the platforms are supported by metallic beams extending lengthwise of the car and secured to the sills or subframe of the car-body, and more especially to a metallic platform structure of this kind which is designed for use in connection with an oscillating buffer pivoted centrally to a center stem and near its ends to side stems, said side stems havin gsprin gs for returning the buffer to its normal position after the car passes around a curve and the center stem having a light spring for holding the buffer in contact with the buffer of an adjoining car and a stiffer spring for resisting the heavy shocks received by the buffer.

The object of my invention is the provision of a metallic platform which is very strong and rigid, which can be produced at comparatively small cost, and which'can be readily substituted for an ordinary wooden platform equipped with a buffer mechanism of the above description.

In the accompanying drawings, consisting of four sheets,Figure 1 is a top plan view,

partly in section, of my improved metallic platform ,showing the same in connection with a buffer of the kind above referred to, the flooring of the platform being omitted to eX- pose the parts below the same. Fig. 2 is a detached top plan of the platform. Figs. 3 and 4. are transverse sections in lines 3 3 and 4: 4., Fig. 1, respectively. Fig. 5 is a central longitudinal section of the platform and adjacent parts, the car-coupling being shown in elevation. Fig. 6 is a side elevation of the same. Fig. 7 is a fragmentary central longitudinal section of the platform with the buffer mechanism removed. Fig. 8 is a crosssection in line 8 8, Fig. 6. Fig. 9 is a sectional elevation of one of the main center beams of the platform and the frame surmounting the same, the near channel-bar of the beam being removed. Fig. 10 is a hori- Serial No. 688,027. (No model.)

section of the metallic buffer-block. Fig. 15 Y isa fragmentary side elevation of the plat: form, partlyin section, showing the through the sills of the car-body.

Like letters of reference refer in the several figures.

A represents the end sill of the car-body, A its longitudinal side sills, and A its longitudinal center sills, these various sills being usually constructed of wood.

B B represent metallic longitudinal beams secured to the under side of the side and center sills A A of the car-body, as shown in Figs. 5, 6, and 8, and extending forwardly under and beyond the end sill A of the carbody, these projecting portions forming the overhanging supports of the platform. These metallic beams extend rearwardly beyond the end sill a sufficient distance to afford a firm connection with the longitudinal sills of the car-body.

As shown in Figs. 11 to 13, each of the side beams B of the platform consists of a pair of channel-bars arranged side by side, with their webs arranged vertically and their flanges facing inwardly or toward each other and secured together by transverse bolts or rivets 17, forming practically a rectangular box-girder. Between the channel-bars are interposed disf ance-pieces or space-blocks b, which are arranged at suitable intervals and'through which the tie-bolts or rivets 2 pass. The

to like parts space-blocks may be solid or of any other suit able construction; but for the sake of lightness they preferably consist of vertical and horizontal flanges or webs and perforated hori zontal and vertical bosses for the passage of the connecting rivets or bolts.

The center beams B of the platform are conbolts which connect the metallie'beams with structed of channel-bars, substantially like the side beams B; but in addition to the short space-blocks b they have a long space-block 11 as shown in Figs, 9 and 10. These side and center beams are secured to the corresponding wooden sills of the car-body by vertical bolts 5 which pass through said sills and the space-blocks b b", as shown in Figs. 8 and 15, and they are secured to the end sill of the car by straps b, as shown in Fig. 3. The platform-beams are preferably provided with separate end pieces I) of malleable iron orother cast metal. As shown in Figs, 10 and 12, these end pieces are formed with reduced inner portions or tenons b", which are fitted in the ends of the box-like beams or girders and secured therein by transverse rivets or bolts. These end pieces are provided with square upright shoulders, which abut against the corresponding ends of the channel-bars of the beam. By this construction the end pieces of the beams can be cast in the desired shape and the channel-bars can be cut off straight or square, thus enabling ordinary commercial channel-bars of the proper length to be utilized, avoiding the expense of cutting the ends of the bars to a special form and materially reducing the cost of the beams.

The center beams B are provided at both ends with such end pieces, while the. side beams have such end pieces only at their front ends, as shown in Figs. 11 and 12. As shown in Figs. 9 and 10, the rear end pieces of the center beams are recessed to receive the bod ybolster, which connects the longitudinal sills of the car-body.

O is the buffer-beam, which may be of Wood and which is supported upon the outer ends of the platform-beams B B, and O are the usual wooden step-sills extending from the buffer-beam to the end sill of the car.

D represents metallic filling-beams or auxiliary platform-beams extending lengthwise from the end sill of the car-body to the bufferbeams and arranged directly above the front portions of the main platform-beams and supported thereon. These filling or auxiliary beams are preferably composed of channelbars and intermediate space-blocks and constructed substantially like the main platformbeams B B. They are provided with malleable-iron end pieces (I, having flanges whereby said beams are secured to the opposing front and rear sides of the end sill A and buffer-beam C, as shown in Figs. 1 and 2. The horizontal fastening bolts (Z which pass through the flanges of the front end pieces d,

also pass through the metallic facing e of the Wooden buffer-beam, whereby said facing and the front ends of the auxiliaryplatform-beams are fastened to the buffer-beam by the same bolts.

D represents auxiliary central beams similar to the auxiliary side beams D, which are arranged directly above the main central platform-beams B and which rest upon the latter. Thesecen tral auxiliary beams do not extend from the end sill of the car-body to the buffer-beam, like said side beams, but terminate at a distance therefrom, and the intervening spaces between the ends of said center beams and the end sill of the bufferbeam are occupied by transverse connectingpieces D D preferably of malleable iron, which end pieces are secured to said intermediate beams and form therewith a rectangular frame, which is secured to the central platform-beams B by vertical bolts f. The platform-floor G is supported on and secured to the beams D D and the end piecesD D and these beams and end pieces are depressed below the end sill and buffer-beam the thickness of the flooring .to render the latter flush with said beams and sill, The connectingpieces D D are formed at their ends with angular tenons or projectionsf, which fit into the open ends of the auxiliary platformbeams D and are secured therein by transverse rivets or bolts f, as shown in Fig. 1.

H is the transverse buffer, arranged on the front side of the buffer-beam and pivoted at its middle to the central buffer-stem land near its ends to the side stems J. These several stems pass rearwardly through openings formed in the buffer-beam in a well-known manner. The side stems are provided with the usual springsj, and their rear portions are guided in the usual lugs or abutmeutsj,

which latter are secured to the inner. sides of the auxiliary side beams D of the platform, as shown in Fig. 1. The center stem I is provided with the customary heavy and light springs K K, and its rear portion is guided in a metallic abutment or block L, arranged between the auxiliary center beams Dof the platform and bearing at its rear end against the rear connecting-piece D of said beams, as shown in Fig. 1. As shown in Figs. 1, 2, and 14, the abutment-block L consists of up- 7 right sideand end walls, a longitudinal socket Z, arranged between the side walls and connected therewith by horizontal webs Z, and a tube or smaller socket Z arranged in rear of the large socketland openinginto the latter. This small rear socket forms a guide for the rear portion of the center stem of the buffer, as shown in Fig. 1, while the large front socket receives the light buffer-spring K. The latter bears at its rear end against ahollow follower M, which latter in turn bears against the rear end of said socket. The heavy buffer-spring K bears against the front end of the abutment-block. The block is secured in place by transverse bolts or rivets Z passing through its side walls and the intermediate auxiliary beams D. The block is provided at its rear end with a tenon or reduced portion 1 which is fitted in an opening or recess i formed in the front side of the rear connecting-piece D As shown in Fig.

14, the large front socket of the abutmentblock is open on its under side to permit the follower M to be introduced into the same.

N is the draw-bar or shank of the car-coup ling, attached at its rear end to the pocketstrap or yoke N. N are the usual followerplates, N the side lugs or plates in which the follower-plates are guided, and N -the draftsprings, arranged between the follower-plates. These side lugs or plates are preferably constructed of malleable iron and secured to the under side of the main center beams B of the platform by the same vertical bolts b which fasten said beams to the center sills of the car-body, these bolts being relieved from shearing strains by lips or stops n, formed on the under side of the long space-blocks b and bearing against the ends of the side lugs, as shown in Figs. 9 and 15. The side lugs are formed with depressed ways which extend inwardly beyond the center beams B and in which the follower-plates slide, and they are provided on the outer sides of said beams with perforated horizontal lugs n, to which are attached longitudinal rods 0. These rods connect and tie together the side lugs at opposite ends of the car.

P is the carry-iron of the draw-bar, which is secured to the under side of the transverse supporting-bar P, which connects the front portions of the main side beams B of the platform, said bar being provided at its ends with lips or flanges which are bolted or otherwise secured to the inner sides of said beams, as shown in Fig. 4.

As shown in Figs. 1 and 5, Q are the usual fiat springs, which center the laterally-swinging draw-bar. These springs abut between their ends against depending hangers or brackets q, secured to the under side of the main center beams of the platform. A removable transverse bolt q passes through the lower ends of these hangers,.and this bolt is surrounded by a thimble or distance-sleeve g which bears against the inner side of the hangers.

g represents inclined transverse braces which extend from the lower ends of the hangers to the under side of the main side beams B, as shown in Fig. 3. These braces are provided at their inner ends with perforated lips, through which the transverse bolt q passes. This construction permits the draw-bar to be readily removed from between the hangers g by simply removing the nut from the bolt q and withdrawing the bolt from the hangers q and the distance-sleeve g R is the usual coupling or pressure-bar, which connects the hollow follower M with the draw-bar.

My improved platform structure is very strong and rigid. The main platform-beams B B, which practically have the form of boxgirdcrs, possess great lateral stifiness and offer considerable resistance to the crushing or compression strains incident to collisions. The short or auxiliary beams D D of the platform, while serving as filling-pieces which raise the floor of the platform to the proper level, also act as compression beams or members which aid in resisting the shocks of collisions.

As the platform structure is made up almost wholly of malleable castings and structural steel no special machinery or tools are required for its manufacture, rendering its cost comparatively small.

The space-blocks or distance-pieces of the metal beams not only prevent crushing of the beams, but also afford a solid bolting or attaching surface for the same and a large bearing-surface for the bolts, which prevents cutting or shearing of the same.

The metallic block L and the rectangular frame D D D which incloses the same, form a very strong and rigid abutment for the buffing-springs, which is not liable to be buckled or otherwise displaced.

My improved platform can be easily substituted for an ordinary wooden platform having a buffer mechanism of the kind herein shown and described.

While my improvements are intended more especially for use in connection with such a buffer mechanism, some of the improvements are generally applicable to passenger-cars, and I do not therefore wish to limit myself to the special use above referred to.
