The same letters denote thesaine partsin all My invention relates to railway-cars; and the object of it is to increase the stability of the car on its trucks, the strength of the trucks themselves, the stability and durability of the axle-bearings, and the strength and lightness of the superstructure, and generally to perfect the adaption of the car to its work.

To these ends it consists in the several detheir elasticity.

(No model.)

I vices and combinations of devices which will be fully set forth hereinafter, and definitely pointed out in the claims.

In the drawings, A denotes a pair of parallel longitudinal beams, preferably I-beams, of wrought iron or steel, which extend from end to end of the car, near its middle, each being about three times as far from the nearest outer edge of the superstructure as from the middle. On these two beams the whole super structure is supported. On them rest the transverse floor-joists B, which are also preferably I-beams, of wrought iron or steel. They are riveted or bolted to the upper sides of the longitudinal beams. Truss-bars B, each composed of a middle part, b, about as long as the distance between the outside edges of the 1ongitudinal beams, and a part, b, at each end, bent at an obtuse angle to the middle part, the two angles being equal, are then in like manner riveted or bolted through the parts b to the under sides of the longitudinal beams opposite to the joists.- The parts [1 in each truss-bar are purposely made not quite long enough to reach the under side of the cone sponding joist when the bar is fastened under the longitudinal beams in the manner described, but must be long enough to reach within the distance to which the ends of the joists can be bent down withoutimpairing The ends of the joists are then subjected to pressure sufficient to force them down into contact with the ends of the truss-bars, which are then riveted or bolted to the under sides of the joists by means of intervening angle-plates, B. The joists are thus cambered, so that when the car is empty the 1 upward tendency of their ends, in counteraction to the downward pull of the truss-bars,

holds the fastenings of the two perfectly'tight.

When, on the other hand, the car is loaded,

the weight is partly borne by the stiffness of the joists, any excess operating to convert the tension on the truss-bars into compression. This construction is shown in Figs. 7 15, and 16. The'truss-bars are preferably formed each of a pair of anglebars arranged side by side. Each joist and truss-bar is arranged either before or behind the wheels, so that the floor of the car may be as low as is consistent with clearing the wheels. The construction of these pair of flanges projecting forward and similar the opposite bar by a pair of cross-braces, c,

the junctions being effected by means of angle-plates and bolts or rivets, or in any other suitable manner. The parts are thus consolidated into one bolster firm against lateral as well as longitudinal shocks. Each of the shoes .0 has between the pairs of flanges which embrace the bars a a circular aperture, with a countersunk or chamfered margin. The aperture is large enough to allow the lower end of a cylindrical hanger, D, to pass freely through and oscillate in it. The hanger is threaded at its lower end and receives there a nut, D, which fits easily in the chamfered or countersunk portion of the casting c. The hanger has radial slots (1 in its lower end, and the nut has corresponding slots, cl, in its outer end, the slots in each case being about half as deep as the nut., The nut being turned so that one or more of its slots register with those of the hanger, one or more keys, d of soft metal, may be inserted in the slots thus registering, and will prevent the nut from turning on the hanger. The hanger has a threaded bore in its lower end, in which is inserted a set-screw, (1 whose thread cuts into the keys, and thus holds them from falling out. The screw must be of such dimensions as to crowdthe thread of the hanger into that of the nut. This construction is shown in detail inFigs. 11 and 12. At its upper end the hanger has a spherical enlargement, d, which fits easily in a correspondingly-formed seat, (2 which is supported between the cross-beams of the truck. The hanger can thus turn in its seat in any direction. The seat has an aperture in its bottom,

through which the cylindrical part of the hanger can freely pass. This longitudinal bolster and its support in the cross-beams of the truck are similar in principle to the bow-shaped hanger described in my Patent No. 274,805, already referred to. The details of construction, however, are materially different, and are promotive of increased strength and economy and accuracy of adaptation of strength to strain.

The arched bar E and the truss-bar E of each side beam of the truck are composed each of a pair of channel or angle bars arranged side by side a littledistance apart. Upright braces E passing between the components of the truss bar below, and those of the arch-bar above, and secured at each end by bolts or rivets passing through the flanges of the beams and the enlarged button-like heads 0 of the braces,

'hold the entire side beam firmly together.

Each bar of the side beam extends in a straight line from the cross-beam each way to the point of first attachment to the axle-box, these points being at opposite ends of the axle-box, and the axle-box F sloping from the middle to each end, to correspond with the directions of the side bars, respectively, as shown in my Patent, Reissue No. 10,289, of February 20, 1883. Immediately over each axle-box F the side beams are re-euforced by a horn-plate, F, which consists of a broad, fiat portion, f, covering the outer end of the box and abutting against the end of the arclrbar, a similarbut larger fiat portion, f, covering the trussbar just back of its junction with the archbar, a web, f connecting the two flat portions extending over them in the form of a rib, and also filling the space between the two parts of both arch-bar and truss-bar, and two horns, f, projecting downward in front and rear of the axle-box.

9 of the drawings. Each plate isfastened by bolts F to the usual plate, F", under the axle box. The cross-beams are double, consisting of a pair of I-beams, G, supported in the usual manner between the arch-bar E and the trussbar E. The depth of the cross-beams between the flanges is made as small. as is consistent with due strength, inorder that the flooring of the car may be as low as possible,

and that there may be sufficient room for the longitudinal bolster 0 below them. A piece of T-iron, or twopieces of channel or angle iron, G, rest upon the cross-beams at each end, being just long enough to cover them, for the purpose of giving an increased. depth where the archbar rests on the cross beams, so that the divergent parts of the arch-bar and truss-bar may make a sufiieient angle with each other.

Each of the seats D, in which the upper ends of the hangers D of the longitudinal bol ster O are supported between the crossbeams, is itself pivoted in a pair of brackets, D, each of which embraces the upper and lower flanges ot' the corresponding crossbeams, and is secured to it by bolts or rivets (1 Both side beams and cross-beams are secured against lateral deflection by means of horizontal braces E, preferably of angle-bar iron, which may be roughly described as V-shaped, the apex of the V being affixed to theouter side of web of one of the cross-beams G, and the sepa- This construction is illustrated partly by dotted lines in Figs. 8-

rated ends being in like manner joined each to one of the side beams by being bolted or riveted to that one of the braces E joining the arch-bar E and truss-bar E, which is'nea-rest the axle-box. Instead of the apex of the V,.

however, there is a shortstraight side, 6, riveted or bolted to the web of the cross-beam, and at each of the separated ends the bar is To preserve the lateral balance of the car, a

of that bar. The hanger also carries on its lower end a stop or washer, IF, affixed to it. A coiled spring, H confined between the two washers, tends by its elasticity to hold the car level on the truck,while it'admits of yielding temporarily'to any sudden shock in a vertical line on either side, and thus mitigates the jar therefrom. The same effect is aided by the construction of the wheels J, which-have bodies orwebs of elastic metal, substantially as described, in my Patent No. 260,593, of July 4, 1882. I also provide cushions above and below the axle-boxes, substantially as set forth in my application for a patent, No. 63,912, filed June 12, 1882. I believe that these devices will make the ordinary springs unnecessary; but,

if desired, they or equivalent sup 'aorting-cushions may be inserted in the usual place between the cross-beams.

I connect the two trucks of each car by a reach, K, vertically and horizontally pivoted at each end to a cross-bearn, as shown atkin Fig. 3. The two aXle-boxesF on each side of each truck are pivotally connected with each other by means of a pair of rods, L, which also have a 'pivotal connection with a pivoted arm, K, projecting from the corresponding side of the reach. The construction is in these respects substantially the same as that shown in my Patent N 0. 274,805, before referred to. In-

stead, however, of pivoting the two rods L to each other and to the arm K, in accordance with that patent, I connect the two rods by a triangular bell-crank, M, which is itself pivoted to the arm K, the pivoting of the two rods being at opposite ends of one side of the triangle, and that of the arm K at the angle The parts of the bell- The planks of the floor run lengthwise of the car, and the floor is boarded with channelbeams 0, whose flanges project outwardly. They are bolted or riveted through angle'plates O to the joists B, and are also fastened by screws 0', or other suitable means, to the edges of the planking, as shown in Fig. 7 in such a position that their upper flanges form an extension of the floor.

strength of the floor, but also afirm threshold I thus not only secure great for the doorsa very important matter in freight-cars.

The frame of the superstructure consists of arching ribs I, of flanged iron, whose ends reuse, by preference, bars whose length somewhat exceeds the breadth of the runningboard, so that they may be turned up at each end to clasp the running-board between them,

while the main part of the length of the bar passes under the running-board from side to side, and is grooved on its under side to embrace the corresponding rib P, near its apex, in front and rear. Each bar is fastened to the corresponding rib by a rivet, and to the running-board bya bolt running through the upturned ends of the bar and transversely through the board. About half of these castings have one of theiruptu rned ends continued far enough up to form one of a series of supports, g, for a hand-rail, Q, which passes through an eye in the upper end of each support, and is fastened there byarivet passing through a trans verse aperture in the support and acorresponding aperture in the rail. Many injuries to brakemen result from the absence of. any. means by which they can steady themselves.

in passing along the roofs of the cars; and to remedy these some freight cars have been equipped with hand-rails, the rail being composed (as is preferable) of lengths of gas-pipe, and these being fastened to their supports by.

screws, so that they can readily be detached. This has resulted in thefts of the gas-pipe to such an extent that the attempt to introduce the hand-rails has been abandoned. With the method of fastening by rivets which I use such thefts are made practically impossible, and

an important means of saving life and limb ismade practicable. Transverse beams I also subtend the middle third of each rib.- I

The covering of the superstructure, both walls and roof, are formed of sheets R, ofcorrugated metal, arranged so that the elevations and depressions shall run continuously from side to side of the car. There are four plates between every two ribs, two covering the roof and one each wall. Each plate is of suitable breadth to cover the space between two ribs, and has at each side a flange, T, which is .applied to the side of the adjoining rib. To avoid the tearing of the plates and startingof the,

The ribs are fastened to ,spectively rest against the upper flanges of fastenings, which would result from riveting;

rivets pass through without contact.

or bolting the plates to the ribs, I cover each I &c.i. 0., arithmetically by a common differrib and the flanges of the two adjoining plates with a strip, R, of tough metal, U-shaped in cross-section, and fasten the rivets or bolts 1- in this and the ribs, the holes in the flanges being made large enough to let the bolts or By this construction, which is illustratedin Fig. 10 of the drawings, I obtain a comparatively-light and exceedingly durable covering, more especially, though not exclusively, useful for freight-cars, and free from that tendency to tear away from the fastenings which has heretofore beena serious and practically conclusive objection to all coverings of plate or sheet iron. Owing to the difficulty of bending the corrugated metal to follow the curvature of the ribs at the eaves, angle-plates I are placed over the ribs at this point, thus giving a per pendicular support to the side sheathing for its full height to the point where it, meets the roof-sheathing. The lower margin of each angle-plate is bolted to one side of the corre-' sponding rib, while the upper part of it is bent sidewise, so as to form a continuation of 'the upright part of the rib. The U-shaped strips R are continued over the angle-plates in the same way as over the ribs. The stopping or starting of a laden car causes an outward thrust on the front or rear end, respectively. sist this with the utmost possible strength, each end is secured to half the length of the floor by arranging the ceiling along the sides that half of the ceiling which is connected with whole weight of the cargo.

the end of the car on which the thrust comes, the shock being thus communicated to the ceiling in that way in which it can be most effectually resisted, and through the ceiling to the floor, which is supported against it by the The strips S arebolted or screwed at their lower ends to the upright sides of strips S of angle-plate, whose horizontal sides are riveted to the upper flanges of the channel-beams O, which border the floor. These angle-plates are arranged between the ribs. The diagonal strips of ceiling are also fastened in like manner to the ribs P, and the uppermost of them are fastened at their upper ends to horizontal strips of ceiling S which line the curve where the side of the car joins the roof.

I makethe axles T of the car largest in the bearing, the journal T projecting from the body of the axle in a form whose cross-section is a circle, and whose longitudinal section is a curve which varies rapidly from the longitudinal direction of the axle for a short distance at each end, and thence very slowly to the middle, as shown in Fig. 14 of the drawings. The precise curvature which I find best is one whose abscisses (or co-ordinates parallel To re-' ence of 2. Of course, I do notlimit myself to these precise increments, as they may be varied within the limits of the general principle which I have stated, and still produce substantially the same result. This form of journal gives a long and nearly level bearing-surface, which has at the same time sufficient curvature to counteract completely any tendency to shifting lengthwise of the axle, while by means of the comparatively abrupt projection at the ends the brass T is firmly locked in its place. The brass has a convex enlargement, t", directly over the axis of revolution, substantially as shown in my application No. 63,912, already referred to.

Thejournal T may be formed in one piece with theaxle, in which case the wheels would of course have to be arranged outside of the bearings. Iprefer, however, to form the journals separate from the axle, and then caseharden them and force them onto the body of joists B and the truss-bars B, the floor-j oists B having their ends sprung down to a deflection within a safe limit ofelasticity before being fastened to the ends of the truss-bars B, to prevent vibration of the joists while the car is moving empty, and when the car is loaded so as to take a portion of each j oist sload directly. to the top flange of the girder A by means of the stiffness of the joist, and the other portion of each joistsload down the truss-bar to thebottom flange of the girder A, substantially as described and shown.
