CAR SIDE. BEARING.

SPECIFICATION forming part of Letters Patent No. 545,255, dated August 2'?, 1895.

Application tiled April l 1, l 8 95 To @ZZ when?, 15 may concern:

Beit known that we, FRANCIS G. SUSEMIHL and AUGUSTUS Tonner, citizens of the United States, residing at Detroit, inthe county 0f NVayne and State of Michigan, have invented certain new and useful Improvements in Car Side Bearings, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention consists in the construction ot a side bearing for cars; audit consists in the construction, arrangement, and combination of the various parts, all as more fully hereinafter described.

This is intended to bean improvement upon the prior patent of F. G. Susemihl, No. 311,618, of February 3, 1885.

In the drawings, Figures l and 2 are t'ront` elevations of the device, showing the parts in different positions. Figs. 3 and 4 are similar elevations of a slightly-modified form of our invention. Fig. 5 is a top plan view of our improved bearing. Fig. 6 is a vertical longitudinal section, and Fig. 7 is a vertical central cross-section thereof.

The object of our invention is to provide a roller-bearing between the car-body and truck which shall reduce the friction between those parts as a car moves around a curve in the track and in which the rollers will always be maintained in proper relation to the upper and lower plates, or car and bolster plates.

A is the bolster-plate, andB is the carplate, these plates being secured by suitable means to the bolster and car, respectively, one above the other. The plate B is centrally apertured, and depending around the lower edge of the aperture is the llange C, iittingin a gain or recess I) in the end of the bolster. This recess has an end opening E, so that any dust or cinders falling through the aperture in the plate may drop out upon the ground.

F is a segmental dat track or runway for the rollers F', which have end trunnions G, jonrnaled in the sides of the carriage II. This carriage is curved longitudinally to conform to the shape of the track F. Its upper edges run within the anges u. on the lower edges of the plate B. These iianges have inwardly-cut grooves b, in which the guidedianges c on the top ot the carriage engage, and thus prevent the dropping of the carriage ordisarrangement Serial. No. 545,372. (No model.)

of the parts when the car-body is lifted from the truck, as in making repairs. On the under face of the plate B, between the flanges a, is a flat segmental circular track or bearing I, which rests on the top of the rollers, forming an opposite runway for rollers, as mentioned for lower plate. It becomes necessary with such a construction of bearing comprising a carriage between the bolster and body to have some means to maintain the rollers always in the same relation to the tracks on which they run, regardless of whether the truck bears on the rollers constantly or not. This we have shown accomplished by means of a single coupling-bar .I in Figs. 1, 2, 5, 6, and 7 and by two of such bars K in Figs. 3 and 4:.

In the single-bar construction we have shown the upper plate provided with an aperture to receive the bar, and on the sides ot the aper ture are the saddle-bearings L, in which the ends of the trunnion L on the top of the bar rest. The carriage is provided with the vertical guides M on the inner face of its sides, in which the circular lugs or bosses N engage and are adapted to slide vertically in the operation of the device. The lower end of the bar engages in the central aperture in the bolster-plate and is preferably formed with an enlarged head d, having curved sides. In use, as the car goes around a curve the upper plate moves on the rollers, and the carriage moves in the same direction with one-half the speed, the coupling-bar maintaining the plates and carriage in proper relation to each other at all times. The different positions of the parts are illustrated in Figs, l and 2, and also in the modification shown in Figs. 3 and 4t.

In the construction embodying the double coupling-bars the bars depend at the ends of the car-plate, and theirlower ends bear against the sides of the bolster. On its inner edge the car-plate is provided with the emergencyflange O, arranged above the face P on the bolster-plate, so that in case the carriage is broken these faces will form a bearing between the car and truck.

From the description heretofore given it is evident that when the bolsterplate is in its normal middle position the rollers will he held in their middle position, as shown in Fig. 6. Justin proportion as the truck turns at an angle to the car in going around a curve the ICC rollers will travel to one end under the top plate, resting on the bolster-plate. It is also .evident that this coupling-bar always controls the relation of the rollers to the plate and maintains them in proper position, regardless of whether the car-plate or bolster-plate bears against the rollers or not.

Although the rollers are normally moved by the contacting plates, yet the coupling-bar is needed to move the carriage or rollers in case the plates should separate or the rollers should tend to become displaced from any other cause, such as gradual displacement.

What we claim as our invention isl. In a side bearing for cars, the combination of the car plate, the bolster plate, a roller carriage between said plates, flanges on the carriage engaging grooves in the car plate, for the purpose described, and means for con` trolling the movement of the carriage on the car plate, substantially as described.

2. In a side bearing for cars, the combination of the car plate, the bolster plate, a roller carriage between, flanges on the carriage engaging grooves in the car plate for the purpose described, and a coupling bar suspended from the car plate acting to control the movement of the carriage, substantially as described.

3. In a side bearing for cars, the combination of the car plate, the bolster plate, the roller carriage between, and a coupling bar suspended from'the car plate, passing through the carriage, and having its lower end engaging the bolster plate for the purpose described.

4:. In a side bearing for cars, the combination of the apertu red ear plate, the apertured bolster plate, the intermediate roller carriage, a coupler having trunnions at the top, saddle bearings in the car plate in which the trunnions are supported, lugs on the side of the bar, vertical guides in the carriage with which said lugs engage, and the head as described engaging bearings on the bolster plate.

5. In a side bearing for cars, the combination of the car plate, the bolster plate, the roller carriage between said plates, and the emergency flanges O, P on said plates, as and for the purposes set forth.

In testimony. whereof we affix our signatures in presence of two witnesses.
