ROSA PEYTON, OF CHICAGO, ILLINOIS, ADMINISTRATRIX OF LARAMIE DOUGLASS PEYTON, DECEASED.

CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 237,124, dated February 1, 1881.

Application filed November 22, 1880. (No model.)

To all whom it may concern Be it known that LARAMIE DOUGLAss PEY- TON, deceased, late of the city of Chicago, county of Cook, and State of Illinois, did invent a certain new and` useful Improvement in Car- Trucks, of which the following is a specification.

The object of the invention is to produce a practical car-truck having the axle journalbearings located inside of the wheels, and having a central support for the car-body, sustained directly from said inside axle-bearings by diagonal trusses, so that when one wheel is passing over a broken rail or any depression in the track the car will be supported by the other threerwheels, and the fourth wheel will be carried over the broken rail or depression without damage. This feature of the truck will prevent many accidents, and it will also make the cars run much easier, since the ends of rails will be passed in the same manner without noise or jar.

The invention also involves the peculiarities in construction of such a truck, in order to provide for a swinging` bolster, so as to allow the car-body a limited lateral movement upon the truck, and, further, to enable the use of elliptical springs, and tof provide proper connections with the peculiar journal-boxes of the independent axles, upon which application for Letters Patent has already been made.

The invention consists in the several novel devices and combinations of devices employed to accomplish the above purposes, all as fully hereinafter explained, and pointed out by the claims.

In the accompanying drawings, forming a part hereof, Figure lis a top view ot the truck with one half of the center plate removed, and with the main frame above one axle-box in horizontal section; Fig. 2, a vertical central longitudinal lsection through the truck-frame, the wheels being removed; Fig. 3, a side elevation of the truck-frame with the wheels removed, one of the axle-boxes being in section; Fig. 4, avertical central cross-section through the truck-frame; and Fig. 5, a bottom view, showing some parts-of the truck-frame.

Like letters denote corresponding parts in all five figures.

A represents the wheels of the truck, which are four in number, and are mounted on the ends of independent axles B, so that in running around curves the wheels on one side of the truck can travel faster than those on the other side. The axles B are arranged side by side, as shown, and their journals are inclosed by boxes C, each ofV which has bearings for two journals. Each box is made in two horizontal parts, a a', which are provided with lugs at their corners, and through these lugs pass bolts b, that secure the parts a a together and connect the box with the truck -framel rlhe two wheels on each side of the truck are arranged at equal distances from a central line, so that they will not have any tendency to twist the truck from the rails in running. This necessitates the placing of the wheels nearer together on one side of the truck than on the other.

The peculiar independentaxles and their boxes are included in a separate application for Letters Patent, and they are not therefore described more fully herein.

The main or top frame of the truck, which rests on the axle-boxes, is composed principally of two diagonal bars,D D', and two side bars, E E. The opposite diagonal bars are parallel with each other at their ends, and extend longitudinally with the truck across the tops of the axle-boxes on their inner sides,and they are then bent laterally toward each other and run parallel, close together, past the center ot' the truck, when they branch out again to the axle-boxes at the other end of the truck. The side bars are straight and connect the axle-boxes at the sides of the truck. Such side bars rest upon' the axle-boxes at their ends, as shown at the outer edge oi' said boxes. Both the diagonal bars and the side bars are made from rolled wrought-iron channel-bars, which have avertical web and top and bottom horizontal anges projecting on one side of the web. Upon the axle-boxes the flanged sides of the diagonal and side bars are turned toward each other, and between each set of bars, to keep them rigidly the proper distance apart, are placed two block-castings, cc', above the ends of the box, and a spool-casting, d, above the center of the box. The side and di- IOO agonal bars above cach box are connected togetherby bolts e, passing through the tlanges of the block-castings c c', while the barsabove the laterallyopposite boxes are connected by tierods or long bolts F, which pass through the dagonal and side bars and through the spools d. The bolts F havenuts on their outer ends, which draw the two sets of bars together at their ends, while upon each bolt, between the bars, is placed a gaspipe, li", which holds the bars and the boxes rigidly the proper distance apart. Above the ends ot' the boxes saddles f are placed across the diagonal and side bars, and the bolts b, which pass up through the lugs of the boxes. extend through these saddles and are provided with nuts on their upper ends, which draw the bars solidly down upon the boxes, and at the same time secure the sections of the boxes together.

Between the central parallel portions ot' the diagonal bars l) 1)' are placed four block-castings, g g', having tlanges projecting on one side only. .lhe end blocks, g, are placed near the ends of the central parallel parts ot' the diagonal bars, and are turned with their flanges inward. The two intermediate blocks g' are arranged on opposite sides ofthe center of the truck, and have their plain sides facing each other. They form between them a. laterallyelongated opening, g2, for the kingbolt ofthe car, so that such king-bolt can move laterally therein across the truck, to allow l'or the swinging ofthe car-body on its bolster, but cannot play longitudinally of the truck. All t'our block-castings g q' are riveted or bolted to the diagonal clianuelbars.

The diagonal bars are connected with the side bars at the center by cross-hars G G', of iiat iron. These tlat crossbars are heilt downwardly at their ends, and rest between the horizontal tianges of the diagonal and side bars, as shown in Fig. 4. There are preferably six of these cross-bars, thc four end bats, G, extending from the endsof the parallel por` tions of the diagonal hars to the side bars, and the two central bars, G', connecting the centers of the diagonal bars and the side bars. These parts complete the upper or main frame of the truck, which,it will be seen, is au exceedingly strong and rigid frame, and has the axle-boxes connected diagonally with a central point, which is braced laterally to give it great strength and stili'ness.

H H are two posts of channel-iron, which, at their upper ends, are secured by rivets or bolts to the end blocli-castiiig,g, and lie between the diagonal channelbars l) D', and may also be secured to them. These posts cxtend downwardly to points a short distance below the level of the bottoms ofthe axleboxes, and have secured to their lower ends a horizontal frame, l, which rests between them, blocks h being placed between the ends of the frame and the posts to make room for side braces, that will be presently described. The frame I is, in general shape, of thc form of the letter X with its ends closed. Through the center of this frame. to give it stidness, runs a bar, l', having T ends. This bar is secured at the center and ends to thc frame I. Four tierods, K, extend from the ends of the trame I, to which they are secured, upwardly and diagonally, to the inner sides of the diagonal channel-hars above the center of' the axleboxcs. 'Ihe diagonal tie-rods K have eyes forged in their upper ends, through which eyes the bolts F pass.

'lhe gas-pipe sleeves F are made ot such length that the eyes ofthe tie-rods are accommodated between thc ends of said gas-pipes and the sides of the diagonal channel-hars, the tie-rods being rigidly held with the other parts when thel nuts on the ends of the bolts F are tightened.

To the lower ends of the posts H H', on their outer Sides, are secured wroughtiron blocks i, which have tlanges at their upper ends, to which tlanges are bolted the inner angles of horizontal V-braces L L', extending from the blocks t' to the under sides of lthe axle-boxes, where their ends are held by two ot' the bolts of each axle-box. 'lhese braces serve to prevent thc wrenching ot' the axle-boxes from position by giving them a bottom as well as top support. llonr side braces, M, extend from the blocks i upwardly and outwardlylaterally to thc side hars, E where their bent ends rest under thc outer ends of the end cross-bars (l. Each pair of the side braces, M, is forged from a single piece ot' dat iron, and is riveted to the blocks i by means of rivets formed directly on such blocks.

The swinging spring-bolster is constructed in the following` manner: It has four lower cross bars or plates, N, and four upper cross bars or plates, O. These are arranged in pairs, as shown, between the posts H H', and between thc main frame and the frame I. Between the ends ot' the upper and lower cross-bars are placed the elliptical springs P. There are eight of these springs, and they are arranged transversely in pairs and secured at their centers to such cross-bars. Each pair ot lower cross-bars is connected at the ends by blocks k, secured on thc under sides ofthe cross-bars, through which blocks pass thetwo lower pivotbolts, l. These bolts i'orm pivots for the links Q, (three on each side,) which extend from hangers R, secured to the side channel-bars, E E'. The links are pivoted t0 the hangers by bolts m. liach pair of upper crossbars,0, is connected at the ends by blocks n, from which rise brace-bars S, extending inwardly and upwardly, between the cross-bars G G', to points above the main frame, where the bracebars are connected by the center plate,'1`, which is bolted thereto. The car-body at one end rests upon this plate, and the king-bolt extends centrally down through it, through the elongated opening g2, and through a. hole in 'a plate, o, which extends centrally across the four upper cross-bars, 1, and binds them all together. By these means the car-body is allowed to swing laterally a short distance on IOO IIO

IIS

the truck, this movement being limited by the length of the opening g2. The king-bolt has two bearings, and the elongated opening g2 prevents the straining of the parts of the bolster.

The-diagonal channel-bars, the posts H H', frame I, and diagonal tie-rods Kform true diagonal trusses between the axle-boxes and the center of the truck.

The swinging bolster is supported directly from the side bars; but these side bars are braced laterally from the center and supported from the center by the upwardly-inclined side braces, so that the weight upon the center plate is finally sustained at the center of the 'truck by the diagonal trusses. Thus it will be seen that the truck possesses all the advantages of safety and ease in running that trucks constructed with diagonal trusses are claimed to have, and at the same time a practicable truck is produced having a swinging bolster and provided with elliptical springs, which are preferable to spiral springs.

The channel bars give the. truck great strength, and, in connection with the other parts,male a strong and rigid structure.

This truck is cheaper and lighter than those now in use, and is much smaller, by reason of being confined wholly within the wheels. The inside bearings being much nearer together than outside bearings, the weight of the car acts with less leverage, and a stronger truck can be produced with lighter materials.
