Application ledvNovember 19, 1901. Serial No. 82,904. (No model.)

To a/ZZ whom t may concern:

Be it known that we, JOHN C. WANDS and FREDERICK R. CORNWALL, citizens of lthe United States, residing at St. Louis, Missouri,

have invented a certain new and useful Improvement in Side Bearings for Railway- Cars, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains ro to make and use thesame, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a side elevational view of our im proved side bearing, showing the same in position on a truck-bolster. Fig. 2 is atop plan view of same on line a b, Fig. l. Fig. 3 is a vertical sectional View on line c d, Fig. 2; and Fig. 4 is a side elevational view.

This invention relates to a new and useful zo improvement in side bearings for railwaycars, the object being to construct the bearing in a cheap and simple manner, so that it can be easily applied and when in position it will provide an efficient antifriction device for carrying loads which may be placed upon it and at the same time take up lateral thrusts due to lurching of the car.

With these objects in view the invention consists in the construction, arrangement, 3o and combination of the several parts, all as will hereinafter be described, and afterward pointed out in the claims.

In the drawings, l indicates the'truck-bolster, and 2 the body-bolster, such parts being 3 5 of usual construction.

8 indicates the bearing-blocks, secured to the body-bolster, said bearing-blocks being concentric to the king-pinv of the truck and `each having a downwardly-extending flange 4o t at its inner edge. (See'Fig. 3.) The lower bearing-faces of these bearing-blocks form fiat treads 5, beyond which are inclined or 'coned portions 6. These body-bearings, as they might be called, have features common to a flanged wheel in that there is a flange and a tread, partially flat and partially coned on each block. The dat portions of the tread are comparatively narrow and join the throat, so as to provide an extended seat for the balls andv enable the body-bearing to coperate with the balls by transmitting the load thereto in vertical direction, (through the flat tread,) the angular and lateralv thrusts being imparted through the throat and depending .iange 7 indicates a casting, preferably made of malleableiron, which casting is provided with 'attaching-lugs, whereby the same may be secured in position on the truck-bolster. This casting has a continuous groove or way 8 in its upper face forming an endless ballrace in which are arranged balls 9. These balls 9 are of such size with respect to their way that they completely fill said way, as shown, forming an endless rowv or chain of balls. We prefer that the bottom of this way be on a horizontal plane, so as to enable the balls to roll around in the way with the least possible friction. One of the outerwalls of the groove or way is cut away, as indicated at lO, for

the purpose'of enabling the body-bearing to preventing side lurching of the lcar-body.

The treads of the'body-bearings rest upon the tops of the exposed balls, those balls in lservice,which may be designated as the burden-carrying balls, being located under the flat portions of said treads. When the truck swings on its pivot, it will be obvious that the body-bearings will displace the exposed row of balls, causing said balls to travel in their `respective ways, and as the advancing balls are housed they force through the endless way the other balls to move into position at the rear end of the exposed portion of the way. The balls that enter and leave the exposed portion of the way practically carry no burden during that portion of their travel that they are under the inclined portion G of the body-bearing block. Said inclined portion, however, will gradu ally apply and grad ually relieve the balls from burden which enter under the ilat bearing-face or leave said lat bearing-face. cut-away portion 10 is such as to provide suftcient clearance for the action of the bodybearing, and therefore the curved end walls of the way serve as guides to skim the advancing balls from under the at portion of the tread and force them into the housing. In service the endless row of balls will enable the frequent substitution of balls in the exposed way, and consequently the life of the bearing will be thereby considerably enhanced.

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

Having thus described our invention, what wc claim, and desire to secure by Letters Patcut of the United States, is-

1. In a side bearing for cars, the combination with au endless row of balls traveling in a horizontal plane, and a body-bearing directly coperating with said balls and holding them in place; substantially as described.

2. In a side bearing for cars, the combination with a horizontal ball-race, of an endless row of balls located therein, and a bodybearing directly cooperating with the balls at one side of said way and holding them in place; substantially as described.

3. In a side bearing for cars, the combination with an endless row of balls all of which travel in the same plane, and a body-bearing havin g vertical and lateral contact therewith; substantially as described.

4. In a side bearing for cars, the combination with an endless row of balls, and a bodybearing having lateral contact therewith; substantially as described.

5. In a side bearing for cars, the combination with an endless row of balls, and a bodybearing having lateral and vertical contact with balls at one side of said endless row; substantially as described.

6. In a side bearing for cars, the combination with anantifrietion device of spherical form, and a body-bearing having a depending fiange and flat tread portion for coperating with said spherical antifriction device; substantially as described.

7. In a side bearing for cars, the combination with an endless row of balls, and a bodybearing having a throat cooperating with the balls at one side of said endless row; substantially as described.
