CAR-TRUCK FRAME.

SPECIFICATION forming part of' Letters Patent No. 577,236, dated February 16, 1897. Application filed June 11, 1896. Serial No. 595,098. (No model.)

To all whom it may concern:

Be it known that I, EDWARD CLIFF, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Oar-Truck Fram es, of which the following is a specification.

The invention relates to improvements in car-trucks, and particularly to the construction of the frames of car-trucks, without regard to the form or construction of the wheels, axles,axle-boxes,springs,sidebearings,orcenter bearing.

The invention consists in novel features of construction, hereinafter described and claimed, pertaining to the side frames of the truck, the pedestals for the axle-boxes at the ends of said side frames, the hinged or removable sections at the bottom and outer side of said pedestals, and the bolster or bolsters connecting said side frames.

The object of my invention is to provide a truck-frame of great durability and efficiency and simple and convenient in construction and use.

The invention will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which- Figurel is a top view of a portion of acartruck-frame constructed in accordance wit-l1 and embodying the invention. Fig. 2 is a side view of same. Fig. 3 is a central section through the bolster and center bearing of same on the dotted line 3 3 of Fig. 1, and Fig. 4. is an end view of a portion of same.

In the drawings, A designates the side frame of the truck, the frames at opposite sides of the truck being counterparts of one another. The frame A is formed at its upper longitudinal edge with the laterally-extending flange B, which at the center of said frame passes inward and forms a substantial extension or plate 0, below which the upper flanges of the channel-iron girders D D, constituting the bolster, are secured by means of rivets E. At the center of the side frames A the flange B also passes outwardly to form a substantial extension or plate F to receive and properly secured by means of the rivets H. At its lower edge each side frame A extends downwardly at its opposite ends, as indicated at I, and along said lower edge each side frame A is formed with the inwardly extending flange J, which follows the general outline of the extension 0 of the upper flange B, but does not extend inward to the same extent as the said upper flange. The outline of the flange J is clearly indicated in Fig. 1, and between the central portion or inward extension 0 of said flange and the extension 0 of the upper flange B are riveted the transverse girders D D, the lower flanges of said girders being riveted to the flange J, and the upper flanges of said girders being riveted to the flange B, as shown.

At the ends of the side frames A are cast the inverted hollow receptacles or boxes K, the outwardly-projecting web-flanges L, and vertical flanges M, the latter formingone side of the pedestals for the axle-boxes. (Not shown.) The flanges L extend outward longitudinally from and centrally with the boxes K, and to said flanges at each end of each side frame is reinovably secured by the bolts N O the frame P, which, when in position, forms the outer side of the vertical bearing or pedestal for the usual axle-boxes.

The upper portion of the frame P is bifurcated, as shown in Fig. 4, to straddle the flange L, and at its inner vertical edge the said frame P is provided with the flange Q, which corresponds and is in line with the flange M, formed directly on the side frame A. At the lower end of the frame P is formed the hub R,Which corresponds with a like hub S, formed at the lower end of the downwardly-extending portion I of the side frame A, and upon these hubs R S are secured upon the bolts T V the bars WV W, which connect the sides of the pedestals and close the space formed for the reception of the axle-boxes. Upon the removal of the bolts V N the bars W and frame P may be swung outward on the bolts 0, so as to leave the axle --boxes and the axles within them in convenient position to be moved outward from beneath the truck.

The bolster is composed of the channel-iron 50 support the side bearing G, the latter being girders D D, which correspond with one an- 10c other and have their flanges extend toward one another. The upper flanges of the girders D D are, as above described, secured by rivets E to the central portion of the flange B, formed 011 the side frames A, and the lower flanges of said girders D D are secured by rivets to the lower flange J, formed on said side frames A. The girders D D are further secured to said frames A by means of the flanges a, formed at their ends and extending outward in close relation to said sides A, to which, by means of rivets b, they are secured. The girders D D are thus secured to both the upper and lower flanges B J and also to the inner faces of the side frames A. The flanges of the girders D D meet one another at the center of the truck, as shown in Fig. 1, and toward the ends of said girdersthe said flanges are sheared away to form tapered openings between the girders for convenience in applying the rivets. At the central portion of the girders D D, where their upper and lower flanges meet one another, are secured the upper and lower plates (lettered cl 6) which connect the girders, and the upper one of which receives the central bearing f, of well-known form. The bearing f is provided with the usual vertical aperture g, and the girders D D and plates (1 e have apertures formed in them in line with the said aperture gin the bearing f, said apertures being provided to receive the king-bolt.

Within the pedestals formed at the ends of the side frames A will be placed the usual axle-boxes, (not shown,) which will have their vertical movement between the flanges M Q, and above the said axle-boxes will be placed the usual or any suitable springs, (not shown whose upper portions will be located within the boxes or receptacles K, provided therefor.

The boxes K are integral with the side frames A, and their halves are at opposite sides of said frames and at such opposite sides connect the flanges M L,which are in line with the vertical center of said boxes.

The parts of the truck-frame, both in their detail and in their relative arrangement with one another, combine to produce a truckframe of great durability and efficiency and simple and convenient in construction and use.

The frames P, forming the outer sides of the pedestals for the axle-boxes and secured by the bolts N O, are of special importance. The bolt 0 forms the hinge of the frame P, while the bolt N serves to rigidly secure the frame in its vertical position. \Vhen the nut on the bolt 0 is tightened up, the bolt N is thereby aided in securing the frame 1. The bolt N is of importance in securing safety, since it will effectually maintain the frame P in position in the'event of any accident happening to the bolt T. If the bolt N were omitted and the bolt T should break, it will be obvious that the bolt 0 alone might permit the frame P to swing out and allow the axle-box to escape from its housing. Ordinarily when it is desired to free the axle-box the bolts T N will be withdrawn, the bars turned down slightly, when necessary, on the bolt V, and the frame' P swung outward on the bolt 0, thus leaving the box entirely free to pass from the pedestal. The spring will not escape with the axle-box, since it is in a well-known manner held by a bolt passing through the aperture at the top of the box or receptacle K. The bolts N 0 will preferably be arranged as shown, the bolt N being in the thickened inner edge of the frame P and the bolt 0 being on a higher elevation at the up per outer end of an upward and outward extension formed at the top of said frame, where the latter is bifurcated to straddle the webflange L, as shown.
