HORACE RESLEY, OF CUMBERLAND, MARYLAND.

RAILROAD-CAR MOUNTING.

SPECIFICATION forming part of Letters Patent No. 441,976, dated December 2, 1890.

Application filed October 4, 1890. Serial No. 367,136. (No model.)

To all whom it may concern:

Be it known that I, HORACE RESLEY, of.

Cumberland, in the county of Alleghany and State of Maryland, have invented a new and useful Improvement in Railroad-Car Mountings, of which the following is a specification.

In all railroad curves the outer rail-track must be elevated above the inner rail in proportion to the radius of the curve, in order to compensate for centrifugal action. The extent of this elevation is as much as four inches in a curve whose radius is six hundred feet.

My invention contemplates the utilization of this centrifugal action, and its secondary effects on such curved track to automatically adjust the trucks to the rails, so that their axles shall be positively adjusted to a radial position, instead of being allowed to adjust themselves, which latter results in the grinding of the flanges of the forward wheels of the trucks against the rails, involving a great tendency to run off the track.

The invention consists in means interposed between the trucks and the floor-timbers of the body of the car whereby the motion which takes place between the two in rounding curves is made to adjust the trucks auto matically to the curve, as hereinafter fully described.

Figure 1 is a side elevation. Fig. 2 is a vertical transverse section through one of the trucks, and Fig. 3 is a plan view of the trucks and floor-timbers of the car applied to a curved track.

In the drawings, A represents the floor-timbers of the body of the car, and B B its trucks, which have at a a strong pivotal connection, so that the trucks can turn in a horizontal plane beneath the car.

Upon each outer end of the cross-bar B of each truck is mounted a wedge-shaped hearing 7), and against its inner face or the face next to the middle of the car there bears another wedge-shaped bearing (Z, which is securely fastened to the bottom of the car-body. The latter bearing is slightly curved on its face.

The operation of these devices is as follows: When the ear is rounding a curve, the outer edge of the car-body and the outer side of the trucks approach each other. This is due to two causes: first, the elevation of the outer side of the trucks due to traveling on the elevated outer rail, and, secondly, eentrifugal action, tending to throw the car-body over, causes its outer side to be depressed. Now as the outer side of the car-body and outer side of the car-trucks come together the incline facings of bearings a on the outer side of the car, pressing upon the inclined faces of bearings b on the outer side of the trucks, forces the outer side of the rear truck to the rear and the outer side of the front truck to the front, thus throwing the trucks into diagonal positions reversed to each other, which brings the axes of the wheels into the radial lines of the curve, and adapting the trucks to move smoothly around the curve without grinding against the rails or having any tendency to run off the same. To cause the inclined bearings to move more freely over each other, the lower bearing may have at its base or lower end an oil-cup c,

which is filled with lubricating-oil, and into which the upper bearing dips so as to keep the adjacent faces of the hearings in a good state of lubrication. This oil-cu p is, however, not necessary with chilled bearings.

By means of my invention as thus depassenger and freight cars of the train, but

may also be applied to locomotives with equal advantages.

Having thus described my invention, what I claim as new is- 1. The combination, with the truck of a 5 car and its body portion pivoted thereto about vertical axes, of a thrust connection interposed between the side edges of the car and the sides of the truck, whereby the approach of these two parts toward each other in vertical 10o directions from the centrifugal tilt of the car on a curve or the elevation of the outer trucks There is also 8 5 on a curve is made to adjust the trucks to the curve, substantially as shown and described.

2. The combination, with the trucks of a car and its body portion pivoted thereto about a vertical axis, of two abutting inclined faced bearings, one located upon the truck and the other upon the body of the car, to cause the motion between the two to adjust the trucks to the curve, substantially as shown and described.

3. The combination, with the trucks of a car and its body portion pivoted thereto about a vertical axis, of two abutting inclined faced bearings, the upper one being located upon the body of the car and the other upon the trucks, and the latter being provided with an oil-cup, into which the upper bearing dips to maintain a constant 1u- DANIEL E.
