RAILWAY-CAR TRUCK.

Specification of Letters Patent.

Patented Dec. '7, 1909'.

Application filed November 9, 1907. Serial No. 4=01,491.

The object of my invention is the provision of means for use in an ordinary diamond car truck side frame which will facilitate the removal or withdrawal of the truck.

bolster. To obtain this result I employ one or more column castings between the upper and lower arch bars with which guiding lugs on the bolster cooperate to limit and restrict lengthwise shifting of the bolster. The lower portions of the columns are recessed to provide an enlarged opening through which the bolster may be withdrawn and freed from the truck after the sup orting springs have been-taken out and the bolster lowered from its-usual and ordinary position.

011" the accompanying drawings I have illustrated two desirable embodiments of my invention.

On said drawings, which form a part of this specification,l igure 1 is a side elevation of a portion of a car truck side frame embodying m invention; Fig. 2 is an enlarged view 0 the central ortion of the side ig. 3 is a vertical frame shown in Fig. 1; section on line 3- 3 of 2, the bolster and springs being omitted; Fig. 4 is ahorizpntal section on line 4-4-. of F1 2 as viewed in the direction indicated by t e. arrows; Fig. 5 is a view similar to Fig. 2 illustrating a modified embodiment of m invention; Fig. 6 is a plan view of the co umn 'castin and shows the column bolts in section; an Fig. 7 is a vertical central section on line 77 of Fi 5, the bolster and springs being omitted.

eferring first to Figs. 1 to 4:, inclusive, it should be noticed that the side frame has the usual upper arch bar 10, the ordinary'inverted or lower arch bar 11, andthe customary tie bar 12. Interposed'between the upper and lower arch bars are a pair of col- .umn castings 13 .each of which is long1tud1- nally apertured for the reception of a column bolt 14 and has at its upper and lower ends spaced lugs or fingers 15 and 16 adapted to overlie the edges of the arch bars to maintain the parts in proper position. Each column casting at its upper portion has a bolster-guiding part 17 beneath which the tutes means for guidin casting is recessed at 18 to facilitate the removal of the bolster 19 which has guiding lugs 20 normally co-acting with the parts 17 to prevent or limit lengthwise or longitudinal movement of the bolster. The enlarged central opening of the side frame, due to the presence of the oppositely disposed recesses" 18, is of greater width than the over all lateral dimension of the bolster and its guiding lugs 20, so that when thesu porting springs 21 are removed and the b0 ster lowered to the position indicated in Fig. 2 so that the lugs 20 are opposite the recesses'18, the bolster may be readily withdrawn lengthwise through the side frame, as is obvious. In order to hold the spring plank 22 in lace, each of the column castings 13 at its lbwer end is sifilpplied with inwardly and outwardly extende ears 23 and 24, res ectively, to which the up tanding flanges o the channel spring'plan .may be riveted or otherwise secured;

Instead of havin two so arate column curved upstan ing mar inal fiangjefli and supported b means 0 a depen'diing web 28 rojecte downwardly from it's under sur ace and supplied with lateral integral braces or brackets 29. The bottom edge of web 28 is of curved shape, as indicated at 30, and the casting at its two bottom ends has ribs or fingers 31 overlapping the edgesof the inverted arch bar 11. Arising from the opposite ends of this casting are the pair or spaced-apart column por-' tions 32 .which with the base of the casting are longitudinally apertured for the accommodation and reception of the column bolts 33. The upper end of each column 32 has similar ribs or flanges 34 overlying the opposite edges of the arch bar 10.- The to portion 'of each column part at 35 constithe bolster 36 in its vertical movements y means of column. Above the spring seat and below the parts 35 the upstandmg' columns are guid 1ng ribs 37 which overlap the sides or the recessed at 38 to permit the ready removal bolster opening is sutiiciently enlarged near its lower portion to permit the bolster and its guiding lugs topass through the opening, thereby permitting lengthwise withdrawal of the bolster through the side frame.

Although I have described the various side frames with some degree of particularity, it will be-noticed that my invention is not limited to the precise structural details shown and described, and that various minor mechanical changes may be made in the side frame constructions Herein set forth without departure from the spirit and essence of my invention.

I claim:

1. In a railway car truck side frame, the

combination of an upper arch bar, a sepaeeaoce rate inverted arch bar, and one or more independent columns between said arch bars, each of said columns having a recess on one face to permit removal of the bolster and also having inte ral therewith a brake hanger support, substantially as described.

2. As an article of manufacture, a column casting adapted for use between the upper and inverted arch bars of a car truck side frame, having a recess on one face to permit removal of the truck bolster and having a brake hanger support integral therewith, substantially as described.

3. As an article of manufacture, a combined spring seat and column casting adapted for use between the upper and inverted arch bars of a cartruck side frame, said casting having a central seat to accommodate springs and at its opposite ends a pair of upwardly-extended columns, the lower portions of the adjacent faces of which are recessed to permit withdrawal of the bolster, each of said columns having a brake hanger support integral iherewith, substantially as described.
