BRAKE-SHOE.v
SPECIFICATION forming part of Letters Patent No. 575,789, dated January 26, 1897.
Application filed MaylS, 1896.
To aZZ whom it may concern:
Be it known that I, FRANK E. CASE, a citizen of the United States, residing at Schenectady, in the county of Schenectady, State of New York, have invented certain new and useful Improvements in Brake-Shoes, (Case No. 391,) of which the following is a specification.
My invention relates to brake-shoes for electric braking apparatus and their mounting, and has for its object to provide a form of shoe and a mounting therefor which may be adapted not only to original installations, but also to old cars of any type.
It consists, briefly, of a special form of shoe which is best adapted to my invention, although the invention is not confined entirely to its use, and a means of preventing the rtation of this shoe, which shall be in a measure independent of the truck and capable of application to all existing apparatus with which I am familiar.
My invention is best understood by reference to the drawings, in which- Figure 1 is a side elevation of the two shoes applied to the axles of a trailer-car without motors. Fig. 2 is a modified form to be applied to a motor-car. Fig. 3 is an enlarged detail view of the shoe in side elevation. Fig. 4 is a plan of the parts shown in Fig. 3. Fig. 5 is a section upon the line 5 5 of Fig. 3. Fig. 6 is a sectional detail upon the line 6 6 of Fig. 3. V
In Fig. 1, A A are the car-wheels; B B, the shoes, which are duplicates. C is a connecting-bar independent of the truck-frame, having lugs c 0 upon its ends to prevent its displacement. D D are retaining-plates secured by bolts to the brake-shoe.
The special construction of the shoe and bar is best shown in Fig. 3. In that figure b b are lugs which are formed upon the shoe, as shown particularly in Fig. 6. Between the lugs the bar C is placed, its action being to prevent the rotation of the brake-shoe. It
makes with the lugs a slightly loose fit, so as not to cramp in turning corners or in minor motions of the axle. The same parts are 7 shown in Fig. 4., E being the car-axle, and K Serial No. 591,366. (No model.)
into the axle, and the set-screw L engages with the collar to take up any play that-may arise from wear of the parts. This is best shown in Fig. 5, which also best illustrates the retaining-plate D. As will be seen from comparison of Figs. 3 and 5, this plate is intermediate between the sets of lugs b b 011 each side of the center, and it is secured by bolts to the body of the brake-shoe. Opposite the plate is a coil-spring f, bearing against the bar C and preventing any rattling of the bar and shoe. The spring f should be just sufficiently stiff for this. The bar C is made a slightly loose fit in the recess formed by the plate D and the shoe, so that the bar will not cramp in vibrations of the axle.
Each of the brake-shoes B is provided at its upper portion with an oil-cup B, having a hinged cover 13 held in closed position by means of a spring-hinge B all as clearly shown in Fig. 5 of the drawings.
N N are the coils embedded in the brakeshoe, their use being well understood.
I is the cooperating disk secured to the axle and forming a friction-surface for the shoe.
Referring now to Fig. 2, I show how a single shoe may be mounted upon an idle-axle of the truck and embody my invention. In this case G is a cross-bar or other convenient portion of the truck, which is not illustrated as a whole, and H is a pin. The bar C is in this figure shown as bent, so as to engage with the cross-bar G, and is held in place by the pin H.
In Fig. 3 the electric connections are indicated at a: 1 but these form no special part of the present invention, being well known in the art.
The construction described is one well adapted to the idle-axles of electric cars or other vehicles, the ordinary forms of brakeshoe being intended only for application to motor-driven axles, and being therefore arranged to be supported upon a part of the motor. As ordinarily arranged these shoes are inconvenient of application to idle-axles and require, when so adapted, to be secured at some pointto the truck-frame, so that their rotation may be prevented. In many forms of equipment the truck-frame is not sufficiently strong to provide for this, and to such apparatus the form of my invention shown in Fig. 1 is well adapted, as it brings no additional strain upon the truck; but in motordriven cars the trucks are ordinarily amply strong, so that the brake-shoe may be used as shown in Fig. 2.
\Vhat I claim as new, and desire to secure by Letters Patent of the United States, is-
1. Adisk eleet-romagnet brake-shoe, having a disk mounted on a ear-axle, and provided on its face with sets of lugs and a retaining"- plate intermediate of said lugs; in combination with a locking-bar located in said lugs and held in position by said plate, the bar being secured to prevent rotation of the shoe, as herein set forth.
