the bolster to be removed with facility when' desired. Each side frame is provided with such a spring pocket which has a flat horizontal bottom, upstanding inner and outer side walls, and vertical end walls, the inner side wall being of less height than the outer side and end walls to permit an end ofthe bolster to extend over and rest upon the springs, terminating just inside of the upper portion of the outer wall which prevents outward longiutdinal movement of the bolster, while the end walls of the pocket guide the bolster in its up and down adjustoutward lon 'tudinal movement of the bolster and si e frame and to tie to ether the nect these walls to ther with a vremovable bolt passing over t e top bolster. The bottom portion of the spring pocket is divided into two compartments or chambers by a transverse web joining the inner and outer side walls. The vertical plate or main beam portion of the bolster is also provided along its top edge witha marginal flange encir cling the sprin pocket, and angle transoms or transverse beams are connected to the side frames by means of rivets fastening theV legs or flanges to the to marginal flange of the frame and to the e walls of the spring and bolster pocket.

In the accompanying drawings I have illustrated two desirable embodiments of my invention, and in these d'rawings like reference characters refer to the same.l parts throughout.

Figure 1 is a side elevation of one form of my improved truck side frame;` Fig. 21s a' lan view of the side frare, the,bolster and lster springs being omitted; Fig. 3 is an inverted plan view of the side frame; Fig. 4 is a longitudinal central section through the bolster and transversely of the`truck side frame; Fig. 5 is a side elevation of a modified fol-ln of truck side frame.; Fig. G is a plan view of the saine' with the bolster and springs omitted; Fig. 7 is an inverted plan view of the structure shown in Figs. 'and "6; and Fig. 8' is a section through the bolster and side frame.

Referring first to Figs. 1, 2, 3 and 4, the side frame includes a bellied vertical plate or'web 10, the top surface of which is somewhat depressed and which is provided centrally with a spring pocket 11 .having a fiat horizontal bottom 12 extending laterally on opposite sides of the plate or web 10, the pocket also havin vertical end walls 13 and 14. The outer' e ges of bottom 12 and end Walls 13 and 14 are connected by a vertical web or outer side wall 15 apertured at 16 for a reduction of weight, While the inner vvedges of the bottom and end walls are joined together by a web or inner side Wall 17 of less height than the Wall 15 to permit the bolster to ass thereover and rest on the tops of sprin s 18 seated in the pocket. The plate or we 10 isl provided along vits top edge and extending from both sides thereof with a substantially horizontal ange 19 which is widened at its central part so as to extend around or encircle the pocket at or near the top of the inner side wall 17. In order to tie together the walls 13 and 14 and to maintain the bolster in place, I pass a bolt 2() through apertures 21 in ears integral with the end Walls and projecting above the top surface of bolster 22. To divide the spring pocket into halves andV connect the inner and outer walls 15 and 17 there is provided a web 23.

I prefer to use angle transoms for the truck and employ a pair of such bars 24 and 25 whose legs or flanges are riveted at 26 and 27 to flange 19 and to one of the end walls 13 or 14. Below pocket 11 plate or web 10 has enlargements or bosses 28 which are a ertured to allow bolts or the like to pass t erethrough and hold in place a pedestal tie-bar 29 against the bottom marginal Han e 30 of web 10.

e construction shown in Figs. 5, 6, 7 and 8 is much like that illustrated in 'the other figures with the dii'erence that the side frame is somewhat shallower or less bellied and is connected to the pedestal tiebar by a bent iron bar or bracket 31 bolted to the tie-bar and to the main body of the side frame. In th' form of my device, however, the bottom ange 32 is widened considerably at its central portion, below the spring pocket, but in other respects this construction is substantially like that shown in the other figures.

It will be ap I arent that longitudinal movement of the bo ster is prevented by the upper portions of the outer sides 15 of the spring pockets while the end walls 13 and 14 of the pockets ide the bolster in its vertical movements. y removing bolt 20 the bolster and side frame may be readily separated and again replaced, after which the bolt 20 is secured in place.

Preferably the side frame is made of cast steelwith all the parts integral though my invention is not limited to such a construction since the frame may be built up ofV parts if desired.

I claim:

1. A car truck side frame having a spring pocket substantially transversely symmetrical with respect to said side frame, and having an outer side wall with which the end of a bolster adapted to extend overgsaid pocket may contact to prevent outward longitudinal movement thereof, substantially as described.

2. In a railway car truck, the combination oi a side frame having a spring pocket sub stantially transversely symmetrical with respect to said side frame, said pocket having iiiiieiand outer side walls, of which the former is of less height than the latter,

springs in said pocket, and a bolster restingon said springs, the end of said bolster coacting with said outer side wall to `prevent outward longitudinal movement of the bolster, substantially as described.

3. In a railway car truck, the'coinbination of a side frame having a spring pocket substantially transversely symmetricalwith respect to said frame, said pocket having an outer side wall, springs in said pocket, and a bolsterresting on said springs, the end of said bolster co-acting with sai outer side wall to ievent outward longitudinal movement oi) the bolster, substantially as de-l scribed.

4. In a railway car truck, the combination'of aA side frame havinv a spring pocket with a bottom and upstanting side yand end walls, the inner sidewall being of less height than the other walls, thereby permitting a bolster to extend over said inner wall, rest upon springs in said pocket, and be prevented froni outward longitudinal movev ment bypthe outer side wall of the pocket.,

and a bolt passing through apertures in said end walls above said bolster, substantially as described.

5. In a railway car truck, the combination of a side frame having a vertical plate and a spring pocket with a bottom and upstanding side and end walls, said pocket being substantially transversely symmetrical top marginal flange encircling said pocket,

substantially as described.

6. In a railway car track, the combination of a side frame having a spring pocket with a bottom and u standin side and end walls, the inner si e wall ein of less height than the other walls, said side frameV having a to marginal flange encircling said pocket, an one or -more angle transoms whose legs are riveted to said top flange and one ofsaid end walls, substantially as de' scribed.

7. A cast metal car truck side frame having a spring pocket with' a bottom and upwardly extended side and end Walls, vthe inner side wallbeing of` less height than the other walls, thereby permitting a bolster to extend over the same and rest on springs in said pocket, and a cross web rising from said bottom and connecting the inner and outerwalls of said pocket, substantially as described.

8. railway car truck side frame having a main vertical plate, and a spring pocket with a bottom and inner 'and outer `'side walls, said pocket projecting from both sides of said vertical plate, and said inner side wall being of less height than said outer side wall, substantially as described.

9. The herein described improvement in car trucks'comprising a single member side iframe adapted to rest u on the top of the journal boxes, the midd e portion of saine being formed as an open topped spring .pocket havin an outer hi h side and an inner low si e and containing bolster columns, substantially as described.

10. The herein described improvement in car trucks, comprising a single member side frame adapted to rest u on tlievtop of the journal boxes, the midd e portion of same being vformed as lan open ltopped spring pocket havin an outer high side and an. inner lowy si e and containing bolster c olumns,"in combination with a bolster locking bar bolted upon the toplof said side frame across said pocket, substantially as described.
