RAILWAY-CAR TRUCK.

Specification of Letters Patent.

Patented Dec. 25, 1906. 4

To all whom it may concern:

Be it known that I, GEORGE G. FLOYD, a citizen of the United States, residing at Granite, in the county of Madison and State of Illinois, `have invented certain new and useful Improvements in Railway-Car Trucks, of which the following is a specification.

The object of my present invention is the provision of a car-truck side frame, preferably but not necessarily of cast metal, which shall have a pocket on thev inner side of the main vertical late or web to accommodate the bolster-springs and the end of the bolster, whereby longitudinal shifting of the bolster is prevented and its removal is easily effected. In such a construction-I have found it desirable to bow the vertical web outwardly and to broaden the top and bottom marginal flanges of the web at the central portion of tinuation or connection between unbowedv portions of the main vertical web.

In. the accompanying drawin s, forming a part ofl this specification, two desirable emodiments of my'lfinvention have been illustrated. A

Figure 1 is a side elevation of one form of my improved' side frame. Fig. 2 is a plan view of the same. Fig. 3 is a section through the bolster and frame showing their co eration. Fig. 4 is a plan view of a mo ified form of said frame, and Fig. 5 is a section through the bolster and modified form of side frame on areduced scale.

Referring first to Figs. 1, 2, and 3, the truck side frame includes a main vertical web or plate 10, bowed outwardl f at 1 l at its central part and provided with t e apertures 12, 13, and 14 for a reduction of weight. Extended inwardly from the bowed portion 11 of web 10 are' two parallel Walls 15, forming ends of aspring-pocket. Along its bottom edge web 10 has a marginal flange 16, projecting from both sides of the web for the greater portion of its length, except along the bowed part 11, where the outwardly-ex-` tended ortion is omitted. This ange 16 is consij erably widened at the central part of the frame to form fa seat 17 for the springpocket, the seat having the bosses or projections 18 integral therewith as centering means for the bolster-springs. Web l0 has a top marginalor peripheral flange 19, extended from both sides thereof and omitted over the spring-pocket. The outer face of the portion 11 of'web 10 has a pair of vertical ribs 20, extending from the flange 19 downwardl .and beneath the spring-pocket to support t esame, as shown 1n Fig. 3. Beneath the spring-pocket these ribs or flanges 20 have apertured enlargements or bosses 21. through which may beV assed bolts or thelike to fasten the pedesta tie-bar 22 in place.

In order to connect together the two side frames of the truck and'maintain them in proper position, I usea pair of angle transp ms or transverse beams 23, one leg of each o1 which is riveted at 24 to one of the walls 15 and at 25 to flange 19.

When the parts of the truck are properl assembled, the bolster-springs 26, of whic any suitable number may be employed, rest upon the spring -seat 17 and sustain the end of bolster 27 and filler-block 28. The bolster is preventetlom moving outwardly longitudinally sincelit fits inside of the bowed portion 1 1 of the web, its vertical movements being guided, bythe pocket-walls 15.

Since there are no parts binding the bolster and the side frame together, it willbe readily understood that the bolster can be withdrawn from the frame merely by lifting it.

In Fi s. 4 and 5 a construction similarto that setv orth above has been illustrated; but

'in this modification the bowed portion of the main web 29 is .much shorter and its side walls 3() are at right angles to web 29 and form in connection with the inwardly-extended walls 31 the end walls of the pocket. As in the previous instance the angle transoms 32 are riveted to the top flan e of the main frame and to the walls 31. Xtended across the top surface of the springseat 33 is 95 a web 34, which is in alinement with and connects the two unbowed portions of web 29, this rib 34 extending u Wardly only approximately one-half the eight of the spring- .pocket to allow compression of the springs and descent of the bolster. This construction is in some respects more desirable than that shown in Figs. 1 2, and 3, for the reason Ioo,

-that the weight of the car-body .is more IIO 2S l i plate forming with the part of said vertical claim-j- 1. A car-truck side frame having a vertical plate or web with a bplster-spring pocket disposed solely on the inner side thereof, subl stantially as described.

2. A car-truck' side frame having a vertical plate portion bowed outwardly, substantially as described. f

` 3. In a car-truck, the conbinatio'n of side frames eachl having a vertical plate portion fbowed outwardly, and a bolster disposed between and prevented from n1ov`ng longitudi- `r nally by the bowed parts of said Avertical plateportions, substantially as described.

4.' A car-truck side frame having a vertical plate bowed outwardly and `walls extended laterally from said vertical plate forming with the part of said vertical plate between said laterally-extended'walls a pocket adapted to.receive the end of a bolster, substantially as described.

.5. A car-truck side fraine l1 aving'a vertical plate bowed outwardly and provided with an inwardly-extended horizontal lflange and walls extended laterally from said vertical plate between vsaid laterally-extended walls and saidY flange a pocket adapted to receive the end of a bolster and one or more bolstersprings, substantially as described. Y`

A6. In a car-truck, the combination of a side frame comprising a vertical plate 'having a top flange and lnwardly-projecting walls, 'y

and transom angle-,bars riveted to said top ange and to said scribed'.

7'. A side frame for a car-truck having a vertical web; top and bottomh narginal' flanges, and inwardly-proj ecting Walls, a portion of said bottom flange, said walls, and a 4o part of saidA vertical web forming al springpocket, said top flange being interrupted over said pocket, substantially as described.-

8. A car-truck f ide framehaving a longitudinal vertical plate bowed outwardly fora 45;"

portion of its length, and a longitudinal-ver tical web connecting the unbowed portions of' said plate, substantially as described.

9. A car-truck side frame comprising alongitudinal vertical plate bowed outwardly JI 'or 5o v GEORGE c. FLOYD. l/Vitnessesq A y FREDERICK C. GOODWIN, WALTER' M. FULLER.
