SPECIFICATION forming part of Letters Patent No. 617,773, dated January 17, 1899.

Application filed January 12, 1898- Serial No. 666.409. (No model.) I

To (all whom it may concern:-

Be it known that I, CHARLES V. Born, a citizen of the United States, residing at Lancaster, county of Lancaster, State of Pennsylvania, have invented certain Improvements in Oar-Brakes, of which the following is a speci lication. 4 p

This invention relates to improvements in that class of brake-shoes or rubbers, brakeblocks, and brake-beams employed on railway-cars; and the objects of my improvements are, first, tolengthen the life of the shoe, and thus save the labor and inconvenience of frequently replacing the same in the brake-block; second, to reduce the amount of metal wasted with the shoe by increasing the relative amount'therein that can be applied to the wheel as a rubber; third, to so construct the shoe as to prevent the breaking of'the same; fourth, to facilitate the attachment of the shoe to the brake-block; fifth,

to construct a brake-block the efficiency of which will not be destroyed by the wearing away of parts thereoffrom accidental engagement with the car-wheel; sixth, to providea brake-beam having two points of connection with the brake-block, and, seventh, tostrengthen the construction of the brakebeam.

In the present construction of those parts the brake-block is secured at its center to the brake-beam, and the brake-shoe is also secured centrally to the brake-bl0ck, the ends of the brake-block having ribs on the ends thereof that bear against the back of the ends of the brake-shoe. By this construction the shoe is not pressed evenly against the wheel, and consequently one end of the shoe wears away much sooner than the other. In putting in a new shoe the same must be inserted between the brake-block and the wheel, and the .work of securing the two together must be done in the limited space between the brake-block and the wheel, which is inconvenientand consumes much time. By reason of the central pivotal connection between the brake-beam and the brake-block when the brakes are off of the wheels the ends of the shoe are held at unequal distances from the wheel, so that as the brakes are applied the end of the shoe nearest the wheel is first engaged therewith and then theother portion of the shoe is brought up against the wheel with a sharp flap, which when the shoe is thin or of imperfect material or when the weather is very cold is apt tobreak the shoe. There is frequent loss of these shoes also, because the brake-block by reason of its construction bears unequally thereon. The shoe is relatively thin,and it must be cast aside when about two-thirds of the same are worn away to avoid the risk of wearing them through and grinding off more or less of the projections on theinner face of the brakeblock, for. as soon as that is done the brakeblock must also be replaced, as when oneof these projections is partly ground off the brake block will no longer bear properly against the back of a shoe, so that for this reason about one-third of each shoe is lost or wasted. This breaking of the shoes is a source of great loss, delay, and expense. In c0nstructions where the brake-block and the shoe are formed together the shoe or rubber portion is relativelythin, and when worn through the brake-block portion is worthless for further use. My improvements overcome the ebjections to the ordinary brake-block and brake-shoe. V

Myinvention consists, first, in the construction and in the manner of applying the brakeshoe; second, in the construction of the brakebloek; third, in the construction of the brakebeam,.and, finally, my inventionconsists in the combination of the various parts, as hereinafter fully described, and then pointed out in the claims. I

In the accompanying drawings, which form a part of this specification, Figure 1 is a perspective view of the brake-shoes, the brakeblocks, and the brake-beam properly assembled and seen from the side on which said shoes are applied to the wheels. Fig. 2 is a rear elevation; Fig. 3, a side elevation; Fig. 4', an inner edge View of one of the brakeblocks, showing the shoes removed; and Fig. 5 is a top plan view of one of the brake-beams and of the brake-blocks attached thereto.

Fig. 6 is a top view of one end of a National brake-beam with a modified form of my improved brake -block attached thereto, and

Fig. 7 a side elevation of said brake-block.

Fig. 8 is a perspective outer end view of one of my brake-shoes, shown detached. Fig. 9 is a side elevation of an ordinary brake-block, shown attached to one of my improved brakebeams.

Similar letters indicate like parts throughout the several views: I

My improved brake-beam and the brakeblocks employed-therewith are illustrated in Figs. 1, 2, 3, 4, and 5. The brake-beam comprises two diagonally-arranged tubular bars A A, which intersect each other at their centers, where they engage the head a of'a horizontally-disposed strut A. The ends of each bar A are connected by a tie-rodA the two tie-rods intersecting each other at and engaging the end a of. strut A. Each of these beams is constructed substantially as the ordinary trussed .tubular beams used for the same purpose; but my beam comprises two trussed bars arranged as described. In strut A is a perforation a, adapted to be engaged by the ordinary brake-lever, (not shown,) and on the inner end of said strut are two perforated lips a whereby a support for said end of the strut is secured thereto, as is usual.

B B indicate the brake-blocks employed with my improved brake-beam. These blocks are formed of two upright side plates or cheeks 15', set far enough apart for the purpose to be described, and these cheeks B are united at the top andbottom by horizontal plates b and at the center by horizontal plates I). They are further united at the top and bottom by diagonally-disposed sockets I), located outside of .end plates 19 and engaged by rods A and through which pass tie-rods A said brake-beams being held in engagementwith the brake-blocks by nuts I) on the-outer ends of the tie-rods and bearing against bosses on the outer faces of said brake-block, as is usual. In each brake-block are two openings b, located between the two end plates b and .the

7 center plate b, in which openings are secured the brake-shoes. 0n the outer edge of each cheek B are two outward ly-extendin g tongues D, the tongues on the opposite cheeks being located opposite the centers of openings b thus forming a continuation of the sides of said openings.

In tongues D are oppositelylocated holes or perforations d, surrounded on the outside of the checks by rims or annu lar flanges d, and through these holes the shoes are secured in the blocks by bolts D, held in place by a split key or keys d On the ends and the center of the inner edges of cheeks B are inwardly-extendin g tongues D The tongues on both the outer and inner edges of said cheeks are separated by curved recesses, said recesses serving to reduce the weight of the brake-blocks, and at the same time the tongues afford a lengthened bearin g for the shoes.

The brakeblocks are supported by the usual hangers E, attached to said blocks at e andto the channel-iron E of the truck-bolster E said hangers engaging between ears b These ears are formed on both ends of cheeks B, so that hangers E may be attached to either end of the brake-blocks.

The shoe comprises an elongated block F, which is inserted lengthwise from the outer side of the brake-block through openings b and the inner end of which engages the wheel. The outer end of the shoe is reduced in thickness and in width, as shown at F, to lessen its weight and the amount of metal that must be castaside when the shoe is worn out. Through the shoe are holes or perforations f, adapted to be ranged with the holes (Z in the checks of the brake-block. The ends of the holes in the reduced end F of the, shoe are surrounded bya rim or annular flange f to give that end of the shoe a bearin g against the sides of openings b".

The shoes are inserted through openings b from the outer edge of the brake-blocks, and for this purpose the hangers E are made somewhat longer than those used with the ordinary brake-block, so that the upper openings in said blocks may be located below channel-iron E. As they are worn away the shoes are moved inward and then securedin their new positions by withdrawing pins D and then again inserting them through registering holes f and (2, respectively, in the shoe and in the cheeks of the brake-block. The shoes can be made of such length as may be desirable, and in any event the amount of metal at the reduced end thereof that must be castaside after the shoe is worn out will be relatively small. tion of the shoe also prevent the same from being broken, and it will by the construction shown and described always be applied to the wheel at the same angle. Should the shoes accidentally be worn down too far, so

that the ends of inwardly-extending tongues D of the brake-blocks are ground off more or The shape and disposiless, the efficiency of said blocks will not be destroyed. As will be observed, the brakeblocks are rigidly secured at both ends to the brake-beam, which is so adjusted on the brakelever that when properly set and the brakes are applied both the brake-shoes are simulblocks in the same manner as the brakebeam is attached to the ordinary brake-block. Otherwise the brake-block and the brakeshoes are constructed as first described, excepting that there is somewhat more distance between the shoe-openings of the brake-block to allow for the passage between said shoes of the end of the brake-beam.

In Fig. 9 is shown inside elevation the application 'of my new brake-beam to" a brakeblock of the ordinary construction. The brake-block M has perforated earsm formed onits ends, through which said shoe is so:

cured to the double or forked end of my brakebeam.

I do not limit myself to the particular construction of the brake-shoe, the, brake-block, or the brake-beam herein shown and described, as it is obvious that many alterations may be made therein without departing from the principle and scope of my invention.
