BRAKE'SHOE.
(No Model.)
ATENT GEORGE KELLY, OF MINERAL-POINT, WVISCONSIN.
BRAKE-SHOE.
SPECIFICATION forming part of Letters Patent No. 610,327, dated September 6, 1898.
Application filed April 7, 1898. Serial No. 676,826. (No model.)
To aZZ whom it may concern:
Be it known that I,GEORGE KELLY, a citizen of the United States, residing at Mineral Point, in the county of Iowa and State of Wisconsin, have invented certain new and useful Improvements in Brake-Shoes; and I do declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in brake-shoes for locomotive-engines, railway and elevatorcars, and the like; and the object is to provide a simple, durable, and efficient shoe for this purpose.
To this end the invention consists in the construction, combination, and arrangement of the device, as will be hereinafter more fully described, and particularly pointed out in the claims.
The accompanying drawings show my invention in the best form now known to me; but many changes in the details might be made within the skill of a good mechanic without departing from the spirit of this invention as set forth in the claims at the end of this specification.
The same reference characters indicate the same parts of the invention.
Figure l is a perspective view of my improved brake-shoe. Fig. 2 is a longitudinal section of the same. Fig. 3 is a transverse section on the line 3 3 of Fig. 2. Fig. 4 is a perspective view of one of the bearing-boxes detached from the shoe. 1 denotes the shoe proper, and its concave face is provided with transverse series of integral dovetail ribs 2 2, the opposite walls of which converge to permit the shoe to snugly hug the boxes when in place.
3, 4, and 5 denote the bearing-boxes, which are formed with integral transverse dovetail keys 6 6, the walls of which converge to correspond to the ribs 2 2.
7 7 denote guard-plates fixed to the parallel sides of the shoe to retain the bearingboxes in place.
It will be observed that the box 3 is formed with three compartments, which may be filled with a suitable plastic or metallic composi-' tion to increase the coefficient of friction be tween the wearing-face of the box and the tread of the car-wheel. It will also be seen that the shoulders 8 8 of the bearing-box extend over the face of the ribs to prevent them from coming in contact with the wheel. The lateral walls of the box 4 converge, while the end walls are parallel, the converging walls serving to retain composition filling in place. The box 5 is also divided into three compartments, the midde compartment 9 being detachable, as shown, its lateral walls converging in cross-section to conform to the dovetail shape of the recess formed between the 0pposite walls of the fixed boxes on either side of it. The base of the compartment 9 is provided with a longitudinal key 10, which fits into a corresponding keyway 12 in the bottom of the recess between the encompassing compartments.
In Fig. 3 I have dispensed with the guardplates 7 7 and used a lag-screw 13 to removably secure the bearing-boxes in place.
Brake-shoes thus constructed last indefinitely, for as soon as the boxes become worn they can be readily replaced, making the shoe as good as new, there being no wear whatever on the shoe proper, thus effecting a great saving in the rolling-stock of a railroad, while at the same time a very superior and lasting shoe is produced, as the composition used for filling the boxes may be of such a nature as to provide a higher coefficient of friction than is produced by the ordinary cast or wrought iron shoes generally.
Having thus fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent of the United States, 1s-
1. The brake-shoe 1 formed with the integral transverse dovetail ribs 2, 2, in combina- .my hand in presence of two subscribing wit- IIBSSQS.
