CAR-TRUCK FRAME.

Specification of Letters Patent.

Application filed May 2, 1208. Serial no. 430,486.

To all whom it may concern:

Be it known that I, WVILLAin) F. Rroimnns, a citizen of the United States, residing at Lancaster, in the county of Erie and State of New York, have invented a new and useful Improvement in Car-Truck Frames, of which the following is a specification.

This invention relates to railway ear trucks of that sort in which side frames have bolster openings permanently closed all around, and are constructed to allow the ordinary bolster having permanently attached column guides to be inserted endwise into the bolster opening.

The objects of this invention are to produce a light, but. strong, rigid and durable east-steel truck frame of this type; also to provide guides of a novel construction for connecting the bolster to the side frames and guiding it in its vertical. movements, and fasten them to the side frames in a novel manner which insures a rigid and reliable re uirin them to be machined or es eciall" finished; also to improve the side frame construction of trucks of this sort in the respects hereinafter described and set forth in the claims.

In the accompanying drawings, consisting of two sheets: Figure l is a-sectional elevation of arailway car truck frame embodying the invention, showingthe inner side of the side frame. 'Fig. 2 is a plan view of one side frame, partly inhorizontal section, in line 2-2, F1g. 1. Fig. 3-is a fragmentary longitudinal sectional elevation of the truck frame in line 3-3, Fig. 2. Fig. 4 is a transverse sectional elevation thereof, in line 45 4? Fig. 3. Fig. 5 isa. pers eetive view, detached, of one of the b0 ster guides and brake hanger brackets.

Like letters of reference refer to like parts in the several figures. p

The truck is of that type in which the two side frames are fitted at their ends to the ear journal boxes and are rigidly connected between the ends by a spring plank or crosspiece and have upright guides for the ends of the bolster wluch are yieldingly supported by springs.

A represents the side frame, and B the spring plank, transom or cross-piece which rigidly connects the side frames centrally. The bolster C is indicated by broken lines in Figs. 1, 2 and 3. Each side frame preferably consists of a trussed frame or casting A. which rests at its opposite ends on the journal boxes, and a tie a which is secured centrally to the depressed central ort-ion of the casting A with its opposite en sextending beneath the journal boxes to which the ends of the casting A and tie bar a are secured by the usual vertical bolts. The casting A has an upper chord a, a lower chord c having a depressed horizontal central portion, and uprightstruts or bolster columns a which join the upper and lower chords and edges of the upper and lower chords and atv a channel beam arranged with its flanges projecting upwardly, but a spring plank or cross-piece of any'other suitable construc-v tion could be used.

E E represent bolster guides which credeteehably secured in seats in the upper portions of. the bolster columns a and are adapted to extend between the usual hide in s on the sides of the bolster to hold the loo star in place between the columns and "The guides .ion, IlLEHllg v rr'; lhe inner 4 side flanges c 5 which muddle He bolster have reces x 3, in the upper cs 'Wh' :h receive 1e columns (ions oi the columns iv the side iiau es e of Vv'il' v 5 the guid s, side hinges. arc tapered somnvlial; shown in "2 and the top es of said guide dang s c and the upper ",8 ol lho seals (2 in ihc sides oi the col- 1 which i inclined a l' i the channo 0 frame and have lugs tan anglethere bolts lo the Weh i only at the Web or the upper chord, c 3, so lhat the bolts :7 act, W (d up, to draw the "0 their seats.

fore largely relieved ing Si'lSi s The between the holster and lire columns, Winch assists in preventing lateral movement of the guides in the plane of the side frame. Consequently the guides could not become displaced even if their securing bolts were broken or worked out, and the guides form a vei g secure and reliable connection between the bolster and the side frame.

i; represents a hearing plate or seat for file bolster springs This bearing plate rests on the spring plank and is provided with recesses or holes to receive the heads of the i securing bolts for the spring plank- The bolt heads hold this hearing plate from lateral displacement.

Cl claim as my invention:

i. The combination of a truck side frame having upright guide columns which are of hannel-shape in cross-section and are proidcd at their upper portions with seats in heir inner edges which increase tlie.\vidth or: the holsler opening and are also provided with seats in their opposite faces, bolster guides which are located in said seats in the inner sides of the columns and have flanges which Swaddle the columns and occupy said seats in the opposite faces thereof, and fastening: devices for socuring said guides on the side frame suhstz-ii'itially as set forth.

combination of o truck side frame having a holster opening", a channeled upper chord over said o 'iening, detachable bolsler guides having body parts which are seated in recesses in the side edges of said bolster opening, said guides having ports extending up into said channeled top chord and fastening devices for securing the upper extensions oflhc guides in ihe top chord and: for secuinp" the body parts of said guides to the side edges of the bolster opening, substantially as set forth.

3. The combination 01 a truck side frame having a bolster opening, a channeled upper chord over said opening, detachable bolster guides having body parts which are sealed 7 sraddle the edge 0% said opening and are loomed in recessed seals in the opposite sides of said frame, said flanges and sea s being and flanges being inclined, and fastening f h for said guide, substantially as set oi't I 5. ,The combination of a truck side frame -b haymg a bolster opening, a detachable bolster. giuide'in said opening having side flanges whic ,said guide havin straddle one edge of-said opening, a projecting bracket-part for supportin a rake beam hanger and a securing bolt or said uide passing through said bracket artan forming the pivotal support for t e brake stantially asset forth.

6. The combination: of a truck side frame beam hangerfsub' having a bolster openi g,- he portion of the framebelow sald'fipelimgt being of U-shape 'in cross -se,ct'i0n-and having horizontal flanges projecting froni'ppposite sides thereof and ol t posts thereof, a spring plank resting on said horizontal flan es, and securing bolts for said spring plan passing through said bolt posts,

substantially as set forth. Witness my hand, this 29th day of April, 25 I908.
