LOUIS O. HUBER, OF HUBER, KENTUCKY.

CAR-BRAKE.

,A SPECIFICATION forming part of Letters Patent No. 310,435, dated January 6, 1885.

Application Iiled June 12, 1884. (No model.)

T0 @ZZ whom 25 may concern:

Be it known that I, LoUIs G. HUBER, a citizen of the United States, residing at Huber, in the county of Bullitt and State of Kentucky, have invented certain new and use` ful Improvements in Oar-Brakes; andI do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure l of the drawings is a top or plan view of my device, and Fig. 2 is a vertical longitudinal sectional view of the same.

The invention relates to that class of brakes in which the brake-shoe engages the inner surface of the car-wheel, and it consists, essentially, in so constructing the actuating mechanism of the brake that the shoe (which slides upon the upper surface of the axle) is forced against a disk bolted to or cast upon the inner surface of the wheel and surrounding the axle. rlhe actuating mechanism consists of a cylinder the piston of which is reciprocated by steam from the boiler, atmospheric pressure, or other proper means, the piston-rod reciprocating a horizontal rod, to which the levers which actuate the brake shoes are connected.

In the accompanying drawings, A A represent the front wheels of a car-truck connected by the axle a., and A A the rear wheels of the same connected by the axle a.

ai a2 are -disks surrounding each axle, and bolted to or cast upon the inner surface of each wheel.

B is a cylinder secured to the locomotive at any proper point, the piston b of which is reciprocated by steam from the boiler, atmosphericpressure, or other proper means.

b is the piston-rod pivoted by its outer end to the plate O, which, when the piston is at the full extent of its outward stroke, stands at a considerable distance behind the front axle, a, of the adjacent car-truck.

Dis a horizontal rod, situated in the central longitudinal line of the truck, its front end being pivoted to the rear edge of theplate C, and its rear end to the front edge of a similar plate, (Y, which stands as far behind the rear axle, ct, as the plate C stands behind the front axle, ce.

E E are similar levers, pivoted at their inner ends to the plates C and O', and having their outer ends pivoted to the projections j' f of the brake-shoes F F. Each brake-shoe F is semicircular in form, its lower straight edge being grooved to tit over and slide uponl the axle below, and its upper curved edge corresponding in shape to the upper half of the adjacent disk a. It' desired, apiece equal and similar to the described shoe may be bolted to it under the edge, thus completing the disk and surrounding the axle.'

From the description it is evident that when the piston-rod b is retracted the horizontal rod D will be drawn forward, and'by means ofthe levers E E the brake-shoes F F will be forced against the inner surfaces of the disks t2 (t2, thus stopping the rotation of the wheels.

rllhe following are some of the advantages of this construction: It is of simple construction and may be made to act very quickly. It causes no wear upon the tread or tire of the wheel, and consequently does not impair its roundness, and it dispenses with the dangerous brake-beam. There are no parts which, it' broken from the mechanism, would be likely to fall under the wheel and trip the same from the rail, and it can be readily and easily applied to atruck of ordinary construction, or removed therefrom, as desired.

Having described my invention, what I claim,'and desire to secure by Letters Patent, Is

As an improvement in car-brakes, the combination, with the axles a a', of the disks ai, rigidly attached to the inner sides of the truck-wheels, the brakeshoes F,sliding upon the said axles to engage the said disks, and provided with central horizontal projections, f, levers E, plates O O', rod D, and mechanism for operating the same, substantially as specified.

In testimony whereof I affix my signaturein presence of two witnesses.

LOUIS O. HUBER.
