Warren THE PULLMAN COMPANY, OF OHIOAGQ ILLINOIS, A CORPORATION OF ILLINOIS.

CAH-TRUOW- Specification of Letters Patent. Application filed September '7, 1905. Serial No. 277,433.

Patented May 15, 1906.

To all whom it may concern: 1

Be it known that I, ETHAN I. Donns, a citizen ot the United States, residing at Pullman, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Oar-Trucks, of which the following is a specification.

This invention relates to a new form of equalizing means for car-trucks which includes integral j ournal-boxes and equalizingbars and which, besides other advantages, dis enses with. the necessity of employing pe estal tie-bars. When my invention is embodied in, a six-wheel truck, the end journal-boxes have each. an integral equalizingbar resting upon the adjacent center journalbox, the two bars of each side being joined and tied to -ether by any approved means, such as a lin In the accompanying drawings Ihave illustrated one embodiment of my invention, like reference characters referring to the same parts throu hout.

Figure 1 isa plan view, part1 in horizon tal section, of a portion of a trucli embodying my invention. Fig. 2 is a side elevation of such a truck. Fig. 3 is an enlarged side ele' vation of: a portion of the truck, and Fig. 4 is a perspective view of one of the journal-boxes and its integral equalizing-bar.

The usual form of wheel-piece 10 has attached to it by means of belts or other approved meansthree pedestals 11, 12, and 13, within which are slidably mounted journalboxes l t, 15, and 16, respectively, each of which has guidii g projections 17, 18, and 19, Fig. 4, the first two of which cooperate with the outer portion 20 of the pedestal, while the latter, 19, engages and. cooperates with the inner portion 21. of its pedestal. Journals of the axles 22, 23, and 24 are rotatably mounted in the journal- boxes 14, 15, and 16 in the usual manner, the axles being supplied with ordinary car-wheels 25. The end journalboxes l t and 16 are each provided with an integral equalizing-bar 26, which has along its lower edge a flange 27 and along its upper edge flanges 28 andf29), the extreme end 30 of the bar having a ilat portion adapted to rest upon the top of the center journal-box 15, the latter having guiding-ribs 36 to hold the end of the bars in position. Each bar 26 has two spaced lugs 31, provided with apertures in alinement.-- 'l he upper edgeoi-eaclnbar is supplied near its central portion with a s ring-seat 33, having an upstanding annular ange 34 to hold the spring in place, the seat and bar being joined by integral brackets 35. When the truck is assembled, the two bars 26 rest upon the top of the center journalbox 15, and a spring 37 is fitted in each seat 33, engaging at its upper end equalizing-bar spring-cap 38, which cooperates with spring block 39 beneath wheel-piece 10. The two bars 26 are tied together by a link 40, pivoted to the lugs 31 by means of pivot-pins 4:1, passin through apertures 32 and through the ends of the link. 'It will be noted that in this form of construction the load which is transmitted through springs 37, each located substantially one-third the distance from the end joui nal to the center journal, is equalized on the journal-boxes, and the equalizin -bars are held together by the link 40, whic 1 also indirectly by means of the journal-boxes ties together the end pedestals, dispensing with the use of a pedestal tie-bar.

Although I have illustrated and described my invention as applied to a six-wheel truck, it is clear that any truck having a plurality of wheels and journal-boxes on a side may be improved by incorporating my invention therein.

My invention is not limited to a single equalizing-bar integral with a journal-box, since it is apparent that a truck may be constructed wherein a plurality of bars integral with a single box rest upon adjacent boxes.

It is obvious that various other changes may be made in the details of such a construction within the principle of the inven tion. llence my invention is not limited to the specific structure illustrated and described except tothe extent indicated in specific claims.

This atcnt is intended to embrace only so much oi the disclosure made herein as is covered by the claims.

I claim- 1. 'In a railway-car truck, a journal-box and an equalizing-bar integral with said box, substantially as described.

2. In a railway-car truck, the combination of two journal-boxes and an equalizing-bar integral with one of said boxes and resting upon the other of said boxes, substantially as described.

3. A six-wheel car-truck having, i n pombiristicii 'cr said truck, and qlifilZll b s iiitegrsiwith en end id resting 119011 the center of tile corresboridmg side, sub- 3 ii; described.
