ROLLER s'lDE BEARING.

SPECIFICATION forming part of Letters -Patent No. 694,549, dated March 4, 1902. Application filed October 14, 1901. Serial Nol 78,632. (No modelJ To if/ZZ whom t may concern.-

Beit known that I, CHARLES F. HUNTooN, a citizen of the United States, residing at the city of Chicago, county of Cook, State of Illinois, have invented a certain newand useful Improvement in Roller Side Bearings, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the ac. companying drawings, forming part of this specification, in which- Figure 1 is a top plan view of my improved roller side bearing, the cover plate being broken away at one end to more clearly show the interior. Fig. 2 is a side elevational view. Fig. 3 is a longitudinal vertical section al view. Fig. 4 is an end elevational view, and Fig. 5 is a vertical cross-sectional view.

This invention relates to a new and useful improvement in side bearings designed particularly for railroad-cars, the object being to construct a device of the character described in a simple and compact form, the parts being readilyassembled anddismantled, whereby repairs can be quickly and easily made.

With these objects in view the invention consists in the construction, arrangement, and combination of the several parts, all as will hereinafter be described and afterward pointed out in the claims.

In the drawings, 1 indicates a base-castin g forming a housing, said casting being provided with perforated lugs or ears 2 at its sides, whereby the device may becsecured in position on the truck-bolster.

3 indicates the side walls, and 4 the end walls. lValls 3 are provided with recesses 5 in their inner faces and at their upper edges, said recesses forming seats and bearings for the roller-spindles. Walls 4 are provided with openings 6 in their lower edges, as shown in Figs. 3 and 4.

7 indicates a longitudinally-disposed partition-wall provided with notches or recesses S in alinement with the recesses 5.

9 indicates a cross partition-wall provided with openings 10 in its lower edge.

11 indicates cover-plate formed with openings 12, through which the rollers protrude,

said cover-plate being secured in position on the housing-casting by means of through-rivets 13.A Y.

14 indicates the rollers, each of which is preferably provided with a bushing or sleeve l5.

ably inclined or formed sloping on each side of the cross partition-wall S) in order that the discharge of water or dirt from the housing may be accelerated.

With respect to the above construction it will be noticed that the rollers, While projecting through the top of the box-shaped housing for contact with the body side bearing, are in other respects inclosed, they being independently rotatable on aloose spindle. The

axes of the spindles are radial to the king-pin of the truck for obvious reasons and, if desired, can also be inclined. The lugs on the cover, which fit into the recesses, serve to lock the axlesagaiust vertical movement, but do not prevent their rotation, said lugs also acting to prevent lateral displacement of the cover. With respect to the recesses 5 it will be noted that they form blind bearings for the ends of the axles. The openings in the ends andcenter walls of the housing prevent the lodgment and accumulation of dust and water. Byinclining the bottom from the center toward the ends moisture which might accumulate or water which might be thrown on the bearing by the. wheels of the trucks is led off.

My improved side bearing is designed especially for street-car service, and owing to the very short curves, sometimes not exceeding a twenty-ive-inch radius, there is an excessive movement of the side bearing on each side of the central line of the trucks, which makes it impracticable to use movable groups of rollers or balls for relieving the friction between the truck and body side bearing, while in my bearing this excessive move- IOO ment is well taken care of by the aniifrietionrollers and axles, which latter have fixed journals, admitting of an unlimited travel of the body-bearing and at the same time always transmitting pressure directly over the truckholsters. rlhe rollers being loosely journaled are free and independent of each other and rotate according to the difference in travel of the different radii. This difference in travel of the rollers on the same spindle makes it impossible for the rollers to become corroded on or locked in any way to the spindle. This plurality of rollers and spindles admits of a large area of contact and a minimum amount of resistance, owing to the rollers being loose and independent of each other. The spindles being arranged on each side of the center of the truck-bolster oii'er lines of contact for the bearing on the body-bolster, which assists in keeping the truck-bolster from rocking. The openings in the end and center walls and the oppositelyinclined bottom wall of the housing prevent dust and water from accumulating in the housing, and in order to permit the VFree circulation of air through the lower walls of the housing the rollers are elevated above said bottom wall, as shown in Fig. 3.

I am aware that minor changes in the construction, arrangement, and combination of the several parts of my device can be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

l. In a side bearing for cars, the combination with a box-shaped base, of spindles loosely journaled therein, and rollers loosely mounted on said spindles, said rollers protruding through the top of the box; substantially as described.

2. In a side bearing for ears, the combination with a box-shaped housing, of a plurality of spindles loosely journaled therein, said spindles being radial to the king-pin of the truck, and a plurality of independently-movable rollers mounted on each of said spindles, said rollers protruding through openings in the cover of the boxshaped housing; substantially as described.

3. In a side bearing for cars, the combination with a boxed-shaped housing formed with blind bearings, of spindles looselyjournaled in said bearings, and rollers on said spindles which protrude through openings in the cover of the box-shaped housing; substantially as described.

4. In a side bearing for cars, the combination with a box-shaped housing, of a plurality of spindles arranged therein, and supported at each end by bearings formed in the side walls of the box-shaped housing, a partitionwall for supporting the middle portions of said spindles, and .rollers mounted on said spindles on each side of said central partition; substantially as described.

5. In a side bearing for cars, the combination with a box-shaped housing having blind bearings in its side walls, a central partition also forming a bearing for the centers of the spindles, spindles loosely mounted in said bearings, and rollers on each side of the central partition, said rollers being loosely mounted on the spindles and independently rotatable; substantially as described.

6. A side bearing for cars, the combination with a box-shaped housing, a loosely-journaled spindle, a bushing loosely mounted on said spindle and a roller fixed to and carried by said bushing; substantially as described.

7. A side bearing for cars, the combination with a box-shaped housing formed with openings in its end walls, and the bottom wall of said housing being downwardly inclined each side of a central line, and an antifrietion device mounted in said housing; substantially as described.

8. A side bearing for cars, the combination with a box-shaped housing formed with partition walls, and the bottom wall of said housing being downwardly and oppositely inclined, means for admitting a circulation of air over said oppositely-inclined bottom wall, and an antifriction-device carried by said housing; substantially as described.

S). A side bearing for cars, the combination with a box-shaped housing, of spindles journaled therein, rollers on said spindles, and a cover-plate provided with openings through which said rollers protrude, said cover-plate also having lugs which are arranged above' the spindles to hold the same against vertical movement, said lugs also serving to lock the cover-plate against lateral movement; substantially as described.

10. In a side bearing for cars, the combination with a box-shaped housing provided with recesses forming bearings, the walls of said housing being thickened in the vicinity of said recesses, spindles loosely journaled in said recessses, and a plurality of rollers mounted on each of said spindles; substantially as described.

1l. In a side bearing for cars, the combination with a box-shaped housing provided with recesses in its side walls forming bearings, a partition-wall also recessed in alinement with said first-mentioned recesses, and forming a middle bearing in the housing, spindles loosely mounted in said bearings, rollers arranged upon said spindles, a cover formed with openings through which said rollers protrude, and lugs on the cover fitting into the recesses above the spindles; substantially as described.

In testimony whereof I hereunto affix my signature, in the presence of two witnesses, this 7th day of October, 1901.
