UNITED sTA'rns PATENT orrroa ETHAN I. DODDS, OF IULLMAN, ILLINOIS, ASSIGNOR TO THE PULLMAN COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

RAILWAY-CAR TRUCK- Patented July 3, 1906.

Application filed October 30, 1905. Serial No- 235.147-

To all whom, it may concern:

Be it known that I, ETHAN I. DoDDs, a citizen of the United States, residing at Pullman, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Railway-Oar Trucks, of which the following is a specification. My invention ertains to the equalizing mechanism of rai way-car trucks and also to the means for tying the pedestals together and involves, among other things, the use of an equalizing-bar integral with one journalbox and resting upon another box. When my invention 1s embodied in a six-wheel truck, the center journal-boxes each have a seat or shelf projecting from each side thereof for the e ualizing-bars, which are integral with the en boxes, to rest upon.- The pedestal tie-bars in this construction are flat and are fastened to the faces of the pedestals.

In the drawings which accompany this specification, Fi ure 1 is a side elevation of a railway-car trudlr embodying'my invention. Fig. 2 is a partial plan view of the same, partly in section. Fig. 3 is a perspective view of one of the end journal-boxes and its integral equalizing-bar, and Fig. 4 is a perspective view of one of the center journalboxes.

The truck comprises the usual wheel-pieces 10, to which are bolted pedestals 11, 12, and 13, in which are slidably mounted journalboxes 14, 15, and 16, the end boxes 14 and 16 each being equipped with an integral equalizing- bar 17 and 18, respectively, the inner ends of which rest upon steps 19 of the center journal-box 15,.

A description of one of the end journalboxes will suffice for all. By referring to Fig. 3 it will be seen that the end box 14 is supplied on its sides with the usual guides 20,

i which cooperate with the pedestal, and it is also provided on its inner side with the integral equalizing-bar 17 mentioned above. Bar 17 has on its upper andlower surfaces integral marginal flanges 21 and 22, respectively, and on its upper surface it is also equipped with an inte ral spring-seat 23, having the integral circu ar flange 24 on its upper surface to retain the spring in place and on its lower surface with the integral bracket members 25, which connect it with the web of bar 17. At its free end the bar is supplied With a horizontal foot 26, adapted to rest upon the adjacent step 19 of the center journal-box 15.

The steps 19 are integral with box 15, and each comprises a horizontal seat 27, having on its opposite sides two ribs 28, which act to prevent displacement of the ends of the equalizing-bars. The seat portion 27 is supported by integral bracket members 29, which are most clearlyshown in Fig. 4. By referring to Fig. 2 it will be seen that the steps 19 and the equalizing-bars are dis osed between the inner and outer plates 0 the pedestals, thereby forming a neat and compact construction.

It will be understood that as the load on the truck is transmitted through springs 30 to the equalizing-bars it is distributed by them upon the journal-boxes, since the bars are integral with the outer boxes andrest upon the steps 19 of the center box.

As a means to tie the pedestals together I employ a flat bar 31, which is bolted to the lower portions of the faces of the pedestals, as is shown in Fig. 1. p

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

I claim- 1. In a railway-car truck, the combination of a journal-box having a projection on its side and an e ualizin bar resting upon said projection, su stantia ly as described.

2. In a railway-car truck, the combination of a plurality of journal-boxes, one of said boxes having an integral equalizing-bar and another ofsaid boxes having a projection on its side on which said equalizing-bar rests, substantially as described.

3. In a railway-car truck, the combination of a journal-box having a projection on each side and a luralit of ournal-boxes, each having an mtegra equalizing-bar resting upon one of said projections, substantially as described.

4. In a rai1way-car truck, the combination of a journal-box having an integral projection on its side, a journal-box having an integral equalizing-bar resting upon said pro jection, the latter having ribs to prevent lateral displacement of said bar, substantially as described.

5. In a railway-car truck, the combination of a pedestal, a ournal-box mounted in said pedestal and having a projection between the inner and outer plates of said pedestal, and equalizing-bar disposed between the inner 10 an equalizing-bar resting upon said projecand outer plates of said second pedestal, the tion, substantially as described. end of said bar resting upon said projection,

6. In a railway-car truck, the combination substantially as described. of a pedestal, ajournal-box mounted in said pedestal and having a projection between the ETHAN DODDS' inner and outer plates of said edestal, a sec- Witnesses: ond'pedestal, a second journa -box mounted WALTER M. FULLER,

in said second pedestal having an integral FREDERICK C. GOODWIN.
