SPECIFICATIONfor ing part 1' Letters 1 111 O-762,871, dated June 21,1904. Application filed June 19, 1903. Serial No. 162.196. (No model.)

Too/ll whom it may concern.-

Be it known that I, J OHN (l'BAliB'ER, a citi- Zen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Trucks; and I do hereby declare the following to' be a 'full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use the same.

My present invention relates to car-trucks, and has for its object to improve the same in the several particulars hereinafter noted.

To such ends the invention consists of the novel devices and combinations of devices hereinafter described, and defined in the claims.

The invention is illustrated in the accom panying drawings, wherein like characters indicate like parts throughout the several views.

Figure 1 is a side elevation, with some parts shown only in diagram, illustrating a cartruck designed in accordance with my pres ent invention; Fig. 2 is a detail in section, with parts broken away, showing the manner in which the bolster-columns are interlocked with the roller-seats. Fig. 3 is a transverse section taken through the truck approximately on the irregular line m w of Fig.

4. Fig. 4 is a plan view showing in detail the transom or tie-bar having in its ends integrally formed roller seats or bearings. Fig. 5 is a bottom plan view of the parts shown in 4, showingalso port-ions of the lower bottom arched bar and tie-bar of the trussed ..side frames.

In Fig. 1 the numeral 1 indicates diagrammatically the wheels of the truck. The

trussed side frames of the truck involve upper arch-bars 2, lower arch-bars 3, and bottom tie-bars 4, which are shown as disposed in the usual way, being secured at their ends in practice to journal boxes. (Not shown.) The lower intermediate portions of the trussed side frames are rigidly tied together and held in alinement by a transverse tie-bar or transom 5, having cast integral with it at its ends roller bearings 6 in the formof flattened heads havingon their upper faces concave roller-seats 7 and having on their lower faces parallel depending flanges 8. The flanges 8 are adapted to embrace the edges of the cooperating lower arch-bars 3 and tie-bars 4 of the trussed side frames, and in this way'the said transom and its flanges 8 not only rigidly tie together the trussed side frames so that they cannot move toward or from each other, but rigidly brace said side frames so that they cannotbe forced out of alinement or, in other words, moved in a horizontal plane out of their set parallel positions. This latter feature I believe to novel-that is, I believe that I am the first to directly interlock the trussed side frames to parts formed integral with the transom or cross tie-bar. I also believe I am the first to form the roller-bearing seats in parts which are integral with the transom.

The bolster-columns 9 rest at their lower ends in depressed seats or notches formed on the upper faces of the roller-bearings 6 between raised flanges 10 and shoulders 11.

The upper ends of the said columns 9 are, as usual, flanged to embrace the upper arch-bars 2 of the trussed side frames. Ordinary nutted column-bolts 12 are passed through the several bars of the trussed side frame, through the roller-bearings 6, and through the upper and lower ends of the said columns 9, and in this way the several parts of the truck just enumerated are rigidly tied together. It will be notedfthat the flanges 8, which'embrace the lower bars of the side frames, extend from,

the one to the other of the column-bolts 12 on a given side of the truck. The said flanges are thus made to cooperate to prevent shearing of the column-bolts, and. the said bolts in turn cooperate to prevent shearing or breaking of the said flanges under twisting or torsional strains upon the truck-frame.

Bearing-rollers 13 rest in the roller-seat7, and combined spring-seats and roller-caps 14, having concave roller-seats 15, rest on the rollers 13. Attheir sides the said combinedcaps and seats 14 are provided with upturned flanges 16, formed in their outer faces with vertical channels 16 for a purpose which will presently appear. The truck-bolster 17 rests at its end on the upper ends of coiled springs 18, the lower ends of which rest upon the combined spring-seats and roller-caps 14.

I in its movements transversely of the truck by means of heavy ribs 19, secured to the latter and working vertically in the channels 17 of the said combined spring-seats and rollercaps 14. At its ends the bolster is shown as formed with depending side flanges 18, which embrace the flanges 16 of the combined spring seats and caps 14. Also, as shown, the guideribs 19 are formed separately from rectangular bars of steel,which bars are riveted to the inner surfaces of the said flanges 18. The truckbolster and the combined transom and rollerbearing are advisedly constructedof cast-steel or malleable iron. This truck, while extremely simple and of comparatively small cost, has been found to be strong, durable, and eflicient in action.

It will of course be understood that the truck described is capable of modification within the scope of my invention as herein set forth and claimed.

What I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a car-truck, the combination, with trussed side frames, of a transom having at its ends flanges which embrace and interlock with the lower bars of said side frames, substantially as described.

2. In a car-truck, the combination, with trussed side frames including columns interposed between their upper and lower bars, of a transom having, at its ends integrally-formed heads that are interposed between the lower ends of said columns and the lower bars of said side frames and separate said column from said lower bars, substantially as described.

3. In a car-truck, the combination, with trussed side frames, including columns interposed between their upper and lower bars, of a transom having at its ends integrally-formed heads interposed between the lower ends of said columns and the lower bars of said frames, the said interposed heads having'flanges or shoulders that interlock with bothof the said parts between which they are interposed, substantially as described.

1. In a car-truck, the combination, with side frames, of a transom tying the same together and formed in its ends with heads having concave roller-seats, substantially as described.

5. In a car-truck, the combination, with side frames, of a transom having its ends directly united to said side frames and formed with concave roller-seats, rollers resting on said concave seats, combined spring-seats and rollercaps resting on said rollers, springs resting on said combined spring-seats and roller-caps, and a bolster resting on said springs and connected to move said combined spring-seats and roller-caps therewith, substantially as described.

6. In a car-truck, the combination, with trussed side frames, of a transom, having at its ends flanges that embrace and interlock with the lower bars of said frames, and having formed directly in integral parts thereof, concave roller-seats adapted to receive the bearing-rollers of lateral motion devices, substantially as described.

7 In a car-truck, the combination, with trussed side frames including columns interposed between their upper and lower bars, of a transom having integrally-formed heads at its ends, which heads are interposed between the lower ends of said columns, and the lower bars of said frames, are provided with flanges or shoulders which interlock with both of the parts between which they are interposed, and are formed with concave roller-seats, adapted to receive the rollers of lateral motion devices, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

JOHN C. BARBER.
