SPECIFICATION forming part of Letters Patent No. 385,177, dated June 26, 1888.

Application filed June 15, 1887.

To @ZZ whom it may concern..-

Be it known that I, JAMES 'I'. GooDFnLLow, of Troy, in the county of Rensselaer and State of New York, haveinvented an Improvement in Metallic Platforms for Railway-Cars, of which the following is a specication.

My present invention is made for rendering the tubular metallic platform stronger than those he'retoforeconstructed without materially increasing the weight or expense of the same; and my said improvements relate especially to the end sills of the platform, the king-bolt plates, and the connections between the kingbolt plates and the end sills, between which are the draw-frames and draw-bar.

These present improvements are especially adapted to use in connection with tubular platform-frames and the connections for the saine, similar to those shown in Letters Patent Nos. 307,846 and 308,034, granted November 11, 1884, and a reference is hereby made to the said patents as illustrating some portions of the connections between the longitudinal tubes.

In the drawings, Figure 1 is a plan View, partially in section,at one end of the car-frame. Fig. 2 is a longitudinal central section. Fig.

. 3 is an elevation at the end of the car-platform.

Fig. 4 is a detached rear view of the end sill. Fig. 5 is a separate elevation of one of the draw-frames- Fig. G is a cross-section through the center of the end sill at the line .fr x, Fig. 4. Fig. 7 is an inverted plan of the upper king-bolt plate. Fig. 8 is a crosssectiony at the kingbolt. Fig. 9 is a crosssection at yy, Fig. 1, in larger size. Fig. 10 is a section through one ofthe follower-plates, at the line z a, Fig. 11.

Fig. 12 is an elevation of the step. Fig. 13 is a crosssection through the clip that unites the step to the tube, and Fig. 14 is an elevation-of the clip that unites one of the stakes to the tube.

The cast-metal parts made use of for uniting the tubes together and the end sills are preferably of malleable cast-iron, so as to possess the required strength, ductility, and toughness. The end sills are made hollow and boxshaped, and the top and bottom edges are parallel, or nearly so; but such end sills are broader in the middle than at the ends, as seen in Fig. l, to lessen weight, and to allow the Fig. l1 is an end view of said- Serial No. 241,356. (No model.)

cars to run upon curves without the sills coniing together at their ends. The end sill may be cast in one piece of metal 5. but l prefer and have so shown the sill made in two pieces, A and A', which are thc counterparts of each other, but handed, such `right and left hand sections ot' the end sill being united by the yoke-piece B and splice-piece C.

The right and left hand parts of lli'eend sill are not only made hollow and boxvshaped and vnarrower near the ends, as before described,

but there are openings in the vertical front and back portions of the end sill, as shown in 2 2, Figs. 3 and 4, the object of these openings being to lessen the weight of the cast metal and for supporting the core within the mold. These openings may be of any desired shape.

In the middle portion of the end sill, where the right and left hand parts come together, an opening is provided for the reception ofthe ends of the draw-frame, hereinafter described, and the top flanges, 3, arc ribbed on their under sides (see Fig. 4) and L-shaped, so as to receive within them the splieepiece C, andthe bolts 5 pass vertically through the splice-piece and .through the flanges 3, and the bolts pass horizontally through the splice-piece and through the vertical portions ot'such fianges 3, so that a very firm connection is made at the upper inner ends ofthe two parts of the end sill.

The yoke-piece B is recessed upon its upper surface (see Figs. 3 and 4) to form part ofthe opening into which the ends of the drawframe are inserted, and there are ribs 7 on the under sides of the end sill-pieces and grooves in the upper surfaces 0f the yoke-piece and bolts 8, passing up vertically through the yoke-piece and through the bottom ofthe hollow end sill for rmly connecting the right and left hand` parts of such end sill together at the lower in-f ner parts of the same, and this yoke-piece is ribbed, as shown in Figs. 3, 4, and 6, for obtaining the requisite strength and lightness.

The longitudinal tubes E E are provided with bolts at the ends, similar to those shown in the aforesaid patents, and in the end sills there are sockets 10 for the reception of the ends of the tubes and holes for the passage of the bolts, so that the nuts of the bolts at the outer surface of the end sill will firmly draw the tubes into the sockets and unite the end sill and tubes together. If the longitudinal tubes E are square, or if wood sills are used in place of the tubes, the sockets for receiving the ends will be shaped to correspond.

The clips b, for connecting the pairs of tubes and the struts cl and T-shaped tie-bars e, correspond to those shown in my Patent No. 308, 034, and the truss-bolts g are similarly arranged and applied,and they pass at their ends through the end sills, and they are drawn up by nuts;

, but in order to prevent-the truss-bolts slipping upon thev tie-bars e, I make use of saddles e', havingjaws upon their upper faces to slip endwise upon the tie-bars e, and grooved under surfaces, into which the truss-bolts g are re ceived, and the end saddle-pieces, e2, are similarly formed; but in addition they are extended upwardly to form side plates, through which the bolts e pass that unite the tie-bars e and struts d. The longitudinal sill-pieces h, flooring h', and the sides that form the inclosure or box of the car are similar to those shown in the aforesaid patent, with the exception that each vertical post or stake H is connected to the tube E by a U-shaped strap, 15, that passes around the tube and through holes inlthe stakeH,and through holes in thesquare plate 16, which plate is placed diagonally, as shown in Fig. 14, and two of the corners are bent backwardly to clip or support the stake, as seen in Figs. 8 and 14.

'Thetransoni-beam k is preferably of wood, inclosed at its edges by trough-shaped metal bars 20, (see Figs. l and 2,) and to strengthen this transom-beam there is a tie-rod, 2l, Hattened in the middle portion to rest upon the sill-pieces H and truss-bolts g, and the round end vportions of this tie-rod2l pass diagonally through this transom-beam and through the end plates, 22, and are drawn tight by nuts, so as to render the transom-beam very st/iff and strong.

f Upon the under side of the transom-beam is eff/ the top plate, L, for the king-bolt 25, and this top plate has flanges 26 at front and back of the transom-beam, and it is secu redthereto by the bolts 27. The center portion of this top plate, L, is a zone-shaped cavity, 28, receiving a similar projection, 29, upon the bottom plate,M, that rests upon and is supported by the central or bridge beam, N, of the truck, and there is a circular recess in the centei1 of the zone-shaped projection 29, receiving `the cylindrical boss 30, that surrounds the kingbolt. By this construction the truck is free to swivel upon the king-bolt. The parts are very strong and light, and the king-bolt plates relieve the king-bolt almost entirely from strain.

Upon the top plate, L, are the tubular anges 32, through which pass the bolts 33, by which the draw-frames P are connected to the top lplate of the king-bolt, so that the tractionforce in drawing the train is applied to the transom-beams of the cars.

The draw-frame is composed of two bars similar to. those shown in Figs. l, 2. 5, and 9. Each bar is made with openings to lessen the weight, and there are flanges along the edges ofthe metal (see Figs. 5 and 9) to strengthen and stiffen the same and avoid too great weight. The bolts 33 connect the ends ot' these drawfralnes directly to the top plate, L, of the kingbolt, (see Figs. 1 and 5,) and the back ends of the draw-frames are slightly convex around the bolts 33, so as to allow for a motion at this point that may result from any spring of the frame or from concussion in backing the train, and a si milar motion is allowed for at the front ends of the draw-frames by the devices next described.

The frontend of each draw-frame is made as a plate,with a circular projection, 36, upon the outer face of the same. These plates pass into the opening between .the right and -left vhand portions'of the end silland the projecstrain upon such bolts. There are cross-bolts at 122,130 tie the draw-frames together,and these preferably pass through tubes that hold the draw-frames at the proper distance apart.

Vithin the draw-frames there are openings for the reception of the ends of the followerplates R. (Shown in larger size in Figs. 9. l0, 11.) These follower-plates are preferably hollow, andthe end portions, 40, pass into the openings in the draw-frames P, and between these follower-plates any suitable spring is introduced, preferably double helical springs, as shown at S, and there is' a bolt, T, passing through the spring and through the followerplates and connecting with the draw-bar U, which draw-bar'may be of any desired character, and it receives the link or other coupling to connect one bar to the next.v The inner end of the draw-bar-rests against the front follower-plate, and a wedge passes through the bolt T behind the rear follower-plate, soI that the springA is compressed when the train is being drawn or when the cars are being pressed together in backing. r

It will be apparent that the draw-frames form a reliable and strong connection between each end sill and the transom-beam, so

that the one part aids in strengthening theother, and these draw-frames are not liable to be bent or injured by any ordinary deflection of the platform, when loaded, or when the car is passing switches or curves in the track.

Upon reference to Fig. 3 it will be seen that the Vertical shaft w forv the brake-chain passes through the top of the box-shaped end sill, and its lower reduced end enters ahole in the .bottom of such end sill, so as to be firmly supported by the end sill without the use of brackets, and the brake chain is wound around the shaft within the end sill, and the opening in the rear of theend sill is sufficiently large to prevent the chain coming intocontact with the metal of the end sill.

Upon the outer faces of the end sills there are vertical ribs 45, receiving between them the blocks of wood or rubber 46, and these are capped with flange-plates 47, to protect them from wear,and the bolts 48, passing through the v cap-plates and blocks and into the end sills,

connect the parts together, so as to form buffers that receive the pressure when the cars are being backed.

The step Y is made of a U-shaped metal bar, the ends of which are notched, as seen in Fig. 13, and there are two coupling-pieces, 50, one at each side of each end of the step, (see Figs. 3, 12, and 13,) and the clip-pieces 5l pass over the tube, and bolts 52 pass through the clip-pieces and through the couplingpiecesand firmly clamp the parts upon the tube, so that the step will be reliably suspended and it will not turn uponz the tube.

I claim as my invention- 1. The combination,with the tubes and trussbolts in a car-platform, of cast-metal end sills that are hollow and-boX-shaped, and provided with sockets cast with the endlsill for the receptiou of the ends of the tubes, and holes for thepassage of the truss-rods, substantially as set forth.
