UNITED STATES PATENT GEORGE H. SEBRING, OF LEHIGI-ITON, PENNSYLVANIA.

RAILWAY-CAR TRUCK.

QPECIFIGATION forming part of Letters Patent No. 650,594, dated May 29, 1900. Application filed October 2, 1899. Serial No. 732,336. (No model.)

To all whom it may concern:

Be it known that I, GEORGE I-I. SEBRING, a citizen of the United States, residing at Lehighton, in the county of Carbon and State of Pennsylvania, have invented new and useful Improvements in Railway- Car Trucks, of which the following is a specification.

My invention relates to improvements in railway-trucks. 7

It has for its objects, primarily, to provide for readily accommodating the movement of the car axles and wheels in their transit over the rails straight ahead, rounding curves, and passing over any inequalities or obstacles, so as not to affect or strain the truck-frame or housings, and to suitably house or inolose the bearings or journals against displacement and yet permit them to readily yield laterally and longitudinally as necessary, and to provide for the convenient oiling or lubricating of the parts, and to otherwise improve the structural features of the truck-frame and its adjunctive parts.

It consists of the combination and arrangement of parts, including their construction, substantially as hereinafter more fully disclosed, and specifically pointed out in the claims. In the accompanying drawings, illustrating the preferred embodiment of my invention, Figure 1 is a view showing it applied for use in a truck. Fig. 2 is a vertical transverse section, and Fig. 3 is a horizontal section, both taken through one end portion or housing of the truck-frame and journals or bearings. Fig. 4 is a detached broken perspective view of the housing or truck-frame. Fig. 5 is a similar view of an oil or lubricant cup or receptacle, and Fig. 6 is a vertical cross-section of the same. Fig. 7 is a detail perspective of the journal-bearing boxes.

It will be understood that I do not limit myself to details as herein shown, as they sembled and rigidly connected by a central connecting-bar ,2, constituting the truckframe. Each of the lateral supports in itself consists of a frame or skeleton work, as intimated, having end housings I for the re ception of the journals or bearings and oil or lubricant cups or boxes presently described, and intermediarily of said housings said frame is subdivided horizontally by a binder-piece or reinforce 1", affording a convenient support and attachment for the usual elliptic springs, upon which is secured the cross-bar or bolster, king-bolted in the ordinary wayto the carbody, none of said latter parts, however, being-shown, as they constitute no part of my invention. Said lateral supports 1 are themselves connected together by a connecting-bar 2, as usual. These end housings 1 1 are themselves open or frame work and inclose or receive skeleton-like or open-work supplementalhousings 3 and have lateral vertical flanges 1 1 to prevent outward displacement of said supplemental housings, the latter playing freely vertically and horizontally between vertical or upright members 1 of said housings and guarded by said flanges, said frame, with its housings, being limited in the vertical yielding movement by the bottom and top horizontal cross pieces or members of said housings.

The lower, preferably rotary, bearings 0r disks 4cl1aVe' their axes journaled in bearings 4, arranged so as to be carried by the supplemental housings 3, the car-axles having journals 5 resting upon or engaging said rotary hearings or disks 4. Suitably disposed within said housings are oil'or lubricant receptacles or cups 6 to furnish lubricant or oil for the car-axle journals, as required, to lubricate the same, said axle-journals having lubricant-feeding disks 7, as usual, and hung above said journals are additional rotary bearings or disks Sin contact therewith,afford ing antifrictional bearings therefor. Said bearings or disks 8 have their journal-bearings in the under sides of boxes or blocks 8, carried by supplemental housings 3, said supplemental housings being cushioned above by springs 3, interposed between cross bars or pieces 3", connecting opposite side pieces of said bearings and the tops of the housings 1 1 to properly hold the same yieldingly in place. The oil or lubricant receptacles or cups 6 each comprises, preferably, a semicircular bottom or cup portion'proper, 6,with its upper inbent edges let into lateral grooves or gains 6 of a top or cover 6, dished or concaved out upon its under side to conform to the car-axle journals, and at the end of said top or cover is a forwardly and rearwardly and upwardly extending plate or flange 6, having a supplyopening 6 through it for replenishing the supply of lubricant or oil in the oil cups or receptacles as required.

In View of the foregoing it will be seen that the undue rigidity, as heretofore has existed between the truck-frame and the car-axles, is overcome by reason of the skeleton-like or open-work nature of the truck-frame and the freedom of play laterally and vertically per-v what I claim, and desire to secure by Letters Patent, is

1. A railway-car truck comprising the skele ton supports, the supplemental housings within said supports, the springs interposed be- 3 5 tween the supports and the housings, the axles extending through the housings, rollers j ournaled in said housings and hearing at difierent points'against the axles, and the oil-cups suspended from the roller-bearings, substan- 4 tially as described.

2. In a railway-car truck, the truck-frame comprising the skeleton-like or open-work lateral supports or frames having open-work end housings, inclosing oil or lubricant cups 45 or receptacles for the car-wheel axle-journals, having their bottoms formed with inbent edges let into grooves or gains in the ends of a top or cover having an extended outer or front portion provided with an oil replenish- 5o ing or supply opening, substantially as set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
