To all whom it may concern: y

Be it knownthat I, WILLARD F. RICHARDs,

l a citizen of the UnitedStates, residing at Depew, in the county of Erie and State of New York, have invented a new and useful 'Improvement in Railway-Car Trucks, of

. bolster must be inserted endwise.

The objects of the invention are to provide a cast steel side frame in which the disposi-A tion of the metal is such as to give the maximum strength and rigidity for the weight of metal used; also to provide a side frame of strong and desirable construction having a bolster guide o ening-which is permanentl closed on all'si es, land bolster guides whic enablev the use with such a side frame ofthe v'ordinarylbolster havin integral or permanently attached guide u s or.' arts; also to so' construct and securev t 44e bo ster guide to and the side frames then slipped into the side vfran'ie that the fastening devices therefor will bellargely relieved from the strains and shocks to 4which the guides are subjected in the use of the truck; also to so construct the parts that the opposite bolster guides can be permanently attachedto the opposite ends of the spring lank orcross plece of the truck frame and t e bolster and 1pts springs laced'in position thereon 'before the spring p k is secured to the side frames, ace over the ends of the arts t us assem led, and secured; also-to orm the brake-beam ha er brackets inte rally with bolster gui es andconstruct t em so as to make a safer and more secure brake beam suspension means; also to improve car truck frames inthe res ects hreinafterdescribed and set forthinteclaims. j I

vike letters of reference referto like part in the several figures. y

The truck is of the .so-called diamond type in which the car journal boxes are iixed in the ends of side frames which are rigidly connected centrally by a spring plank or cross-piece and the bolster is s ring-supported with its ends arranged to s 'de vertically in guides on the side frames. T

A A represent the side frames, B the spring plank, transom, or crossiece, connecting 8 the bolster, and D the bolster supportin springs.

Each side frame re erably consists of a cast steel body whlch rests at its opposite ends onthe journal boxes a., and horizontal straps a which are riveted or otherwise secured to the lower end portions of the body and extend beneath the journal boxes to which they, together with ends of the boldly, e cast steel body of the side frame has an upper or compression chord a2, which is prefera ly arched on the arc of a circle, a lower or tension chord a,3 having inclined ends joining the ends of the upper chord, and vertical struts or pieces a4 connecting the chords and with them forming a bolster Iguide o ening which is closed on al1 sides by integra parts of the side frame body so that the bolster can only be inserted endwise or laterally therein. The several members'of the body are substantially channel-shaped in cross section with the open sides o the channels facing inwardl or bounding" the'triangular op'ention of the same. Fig. 6 is a horizontal sec in s a6 ormed by the members between the The spring plank or `cross-piece B, shown ranged with its flanges-projecting u wardly, but `a bar or bars of ang other suita leA form and arrangement coul be used.

AThe bolster C (shown) is of hollow cast steel construction having integral vertical guide lugs or parts c on opposite sides of its ends, but it could be of any other suitable construction.

E E represent bolster guides which are secured in the bolster openings of the side frames and embrace the ends of the bolster between its guide lugs @whereby the bolster ties the side frames together and is guided in its vertical movements. Each guide is of substantially U-shape or has vertical-sides connected at the bottom and open at the top to receive the bolster. The guides are riveted or .otherwise suitably attached at their lower portions to the opposite ends of the spring plank, their lowerside portions being preferably extended, as shown at e, Figs. 6 and 7, to make a more secure connection, and when a channel or other single beam is used for the spring lank, each guide A is preferably made in two. alves which are separately secured to the spring plank (see Figs.. 5-7) as thereby the guides can be.

tightly fitted and riveted to the spring lank notwithstanding slight inequalities or dbviation of dimensions in the parts. Each guide could, if preferred, be cast in a single piece,

as shown at E', 8, in which case, however, se arate angle or other bars B are em ployed or the spring plank and separatel secured to the sides of each guide. 'Eac bolster guide, whether made in one or two parts, has a laterally extending U-shaped ange e which enters the bolster opening of the side frame and bears against the bottom and sides thereof, and a vertical flange e2 which rests against the inner face of the side frame and is fastened to the side framebv suitable bolts e3. The bolster o ening is peferably tapered slightly and 't e lateral nge e of \the guide is correspondingly i tapered so as to wedge into .the opening and put the insure a snug fit when the fastening bolts are 'screwed up; As the flanges of the guide bear against the inner face of the side frame and enter its bolster o ening, they receive and resist all thrusts an strains on the guide except such as act inwardly or in a direction opposite to that in which the guide is slipped into the bolster-opening, and the fastening bolts e3 are relieved. of all shearing strains andare required only to hold the guide in the bolster opening.

The construction described makes it possible to permanently fasten the two guides' to the o posite ends of the spring plankB,

bolster springs in place on the spring plank and drop the bolster vertically into place in the guldes with the upright sides 'of the guides engaging between the guide lugs on the bolster, and after these parts are thus assembled, tojslip the side frames laterally over the guides and bolt'the guides thereto, which materially facilitates the assembling of parts of the truck frame. It is to be noted that the bolster is of substantially the length ofthe spring plank, or long enough to project at oppositeends into the bolster openings of the side frames, but that it can be dropped vertically into the guides, which are open at their tops for this purpose.

F F, Figs. 2-4 and 7, represent brake hanger brackets. The two brackets for one side of the truck are cast integrallyr with each bolster guide and extend inwardly from the upper ends of the side pieces of the guide. Each bracket is preferably formed with two laterally projecting bolt lugs or parts f be tween which the upper end of the hanger loop f engages, and a vertical bolt or pin f2 passing through the lugs outside of the loop prevents the disengagement of the loop. By this` arrangement of the lugs and bolt the latter is relieved from the strains resulting from the pulls and thrusts on the hanger loop which are taken directly by the lugs f. The upward thrusts of thel loop are in a direction away from the bolt f2 and the downward pulls thereon tend to hold the bolt in place rather than to dislodge it. Colisequently there is little. chance of the bolt being broken'or dis laced and the hanger loop detached from t e' bracket. rlhe hanger brackets can be more expediently and economically cast with the bolster guides than directly u on the large bodies of the side frame, an the additional fastening devices, which are required when the hanger brackets are made separate from the side frames, are not necessar The hanger brackets are also preferab y formed with lateral flanges f3 which strengthen them and also aid in confining the hanger loops.
