To aZZ whom it may concern.-

Be it known that I, CHARLES V. Born, a citizen of the United States,residingat Lancaster,

county of Lancaster, State of Pennsylvania,

have invented certain Improvements in Car- Brakes, of which the following is a specification. I

This invention relates to improvements in that class of car-brakes wherein a brake-shoe is applied to a rail of the track to retard or stop the movement of the car, and itis more particularly applicable to cars propelled by electricity or by any kind of motor.

The objects of my invention are, first, to retard the movement of a car more effectively and to stop it quicker than is done by the brakes now in use, and, second, to preventthe burning of the wheel when it skids under the pressure of the brake.

The invention consists in the combination, with a Wheel brake-shoe, of a rail brake-shoe, a brake-lever fulcrumedon the rail-brake- .shoe through a pivot, and an operating connection between the brake-lever and the wheel brake-shoe.

The invention consists also in the combination of various details of construction, as hereinafter fully described, and then pointed out in the claims.

My invention is illustrated in the accompanying drawings, forming a part of this specification, and in which- Figure 1 is a top plan View of a car-truck, showing a mode of operating my improved brake; Fig. 2, an elevation of an outer side of the car-truck, the parts being shown in the positions occupied thereby when the brakeshoes are applied, respectively, to the rail and to the wheels; and Fig. 3, a vertical section on broken line 3 3 of Fig. 1, the brake-shoes and the parts connected therewith being shown in their normal positions. Fig. 4 is a top plan View of the brake-supporting frame on one side ofthe car-truck; Fig. 5, a longitudinal vertical section of the rail brakeshoes and the rail brake-blocks on one side of the truck and of their connections with the turnbuckle uniting them; Fig. 6, a longitudinal section of the coupling-joint between the brake=shoes on one side of the truck, taken on broken line 6 6 of Fig. 5; Fig. 7, an

enlarged top view of one of the' rail brake blocks, Fig. 8, an enlarged vertical section of the brake, taken on. line 8 8 of Fig. 2; and Fig. 9, an enlarged side view of a brake-lever, a wheel brake-shoe, and the support of the wheel brake-shoe. Fig. 10 is a perspective inner face view of a wheel brake-shoe; Fig. 11, a perspective outer face view of said brakeshoe; Fig. 12, a perspective top view of a rail brake-shoe, and Fig. 13 an inner face view of one of the standards supporting the wheel brake-shoes.

The drawings and the specification show and describe the application of my invention to a single truck, the description referring to the construction on one side of said truck.

Similar letters indicate like parts throughout the several views.

Referring to the details of the drawings, A indicates the longitudinal members of a wooden rectangular truck-frame; A, transverse members of said frame; A the carwheels, and A the car-axles.

B indicates the car-axle boxes, and those on each side of the truck are connected by two parallel bars B. On bars B and adjacent to car-wheels A are secured standards B and on the upper ends thereof are short inwardly-extending cylindrical arms Z). Each arm 12 engages in a vertically-elongated eye d of a hanger or depending rod d, having its lower end threaded and taking into the upper end of anuprightly-disposed turnbuckle D, the lower end whereof engages a threaded extension Won the upper end of the wheel brake-block D, to which is secured the wheel brake-shoe D On the upper end of the outer face of wheel brake-shoe D are two outwardlyprojecting jaws 01 that embrace the upper end of wheel brake-block D, through openings in which and in jaws (1 said wheel brakeblock and wheel brake-shoe are separably connected by a split key or pin (Z and on the lower end of the outer face of wheel brakeshoe D are also formed two jaws (1 that simply embrace the sides of wheel brake-block D. On the outer face of said wheel brakeblock D is a lug d provided with an opening through which said wheel brake-block D is secured between the jaws of a brake-lever to be described. The turnbuckles D serve to adjust the vertical positions of wheel brakeshoes D Inside of each of the two wheels on the same side of the car-truck is a fiat-rail brake-shoe E, adapted to be applied to the rail. This rail brake-shoe is pointed and rounded at the ends, so as to better take over any inequalites in the rail. On rail brakeshoe E is a centrally-located longitudinal rib E, that engages a groovef in the under face of rail brake-block F, the sidesf of rail brakebloek F resting on rail brake-shoe E outside of said rib E, and on rib E are two perforated lugs '6, through which perforations and corresponding perforations in sides f of the rail brake-block the rail brake-shoe and said brake-block are bolted together, and on top of rail brake-block F are two upwardly-extending jaws f embracing the outer faces of the jaws of the brake-lever.

A bent brake-lever G G is connected with each pair of brake-blocks just described, as clearly shown in Figs. 2, 3, 5, and 9, which levers are located behind wheel brake-blocks D and above rail brake-blocks F. The upright power-arm G of each of these levers is spread laterally, as shown at g, to form downwardly-extending jaws g, and said jaws are bent at g toward wheel brake-blocks D and form the approximately-horizontal weightlever arm G. Both jaws of said arm G pass between jaws f on rail brake-block F, to which they are pivotally secured by abolt f Lever-arm G is extended beyond jaws f toward wheel brake-block D and has its outer ends g turned downward between jaws f of rail brake-block F and embracing lug d on the back of wheel brake-block D, to which it is pivoted by a bolt 9 Jaws f of rail brakeblock F have recesses f in their upper edges to receive the ends of bolt g when lever-arm G is depressed in taking off the brakes.

In the outer end of the upright arm of one of each pair of brake-levers is a slot 72, in which is a sheave h, and in the outer end of the other upright arm of each pair of brakelevers is an eye 7L2.

On the contiguous ends of each rail brakeblock F is formed a heavy horizontal cylindrical extension K, and said extensions have in their outer ends threaded sockets K, engaged by heavy screws M. On the outer ends of screws M are thick plates M, adapted to be bound together by bolts m, and on the meeting face of one of the plates M is a feather m, constructed to engage a groove m in the meeting face of the other plate M, and on the screws M are jam-nuts m The brakeblock extensions K, with the screws M and their connections, are a strut that prevents the rail brake-shoes from being forced outward from the car-wheels, and they form a turnbuckle, whereby the horizontal positions of said rail brake-shoes relative to the wheels may be regulated. The brake-shoes are normally held away from the rail and the wheels by springs G each spring having one end secured to the upper end of a brake-lever and the other end to some part of the truck-frame outside of the lever, the tension of these springs being regulated by turnbuckles g The movement of each brake-lever G G under the influence of its spring G is limited by the engagement of bolt g in recess f of jaws f of the rail brake-block F.

As will be observed, the action of each bent lever G G and its connected brake-blocks and brake-shoes is that of a pinch-bar, the rail brake-block F and brake-shoeE constituting the f ulcrum-foot, adapted to bear on the trackrail, and the wheel brake-block D and brakeshoe D the projecting snout taken under-and adapted to bear against the caravheel. Vhen the brake-shoes are applied, the strain upon the brake-levers occasioned by the relative position of the rail brake-shoes is relieved by the reaction of the wheel brake-shoes through turnbuckle K M M and the horizontal arms G of levers G G. The connection of wheel brake-shoe D with'standard B through arm b and the elongated eye (1 of rod (1 permits the automatic adjustment of wheel brake-shoe D to its proper bearing on the wheel when the brakes are applied, which adjustment is facilitated by the character of the connection between the brake-lever, the railbrak e-block, and the wheel brake-block, these connections forming a toggle-joint between the axis of the wheel and the bolt pivoting the brake-lever to the rail brake-block.

When the brake is applied, the upward I pressure from the rail brake-shoe on the wheel brakeshoe tends to lift the wheel from the track, and the harder the brake-lever is applied the greater becomes the upward pressure on the wheel. This upward pressure takes a corresponding amount from the pressure of the wheel on the rail, and it decreases said pressure of the wheel on the rail to such an extent as to prevent the burning of the wheel when it skids on the rail.

Fig. 1 illustrates one mode of applying my brake, wherein N N indicate the usual handwheel and brake-rod at each end of a car. n is a chain connecting hand-wheel and rod N with an arm n of a lever N which arm n is again connected with a trace-bar 1, adapted to slide in horizontal slots in hangers P, and to each end of trace-bar P are attached traces P each of which extends to and around the sheave in the upper end of one of each pair of lever-bars and to the end of a rod g, pivoted in the eye 7L2 of the companion lever-bar, to which rod g the trace is secured. The other hand-wheel and rod N are connected with the end of a lever R by a chain 7', which lever R is connected with the arm n of lever N I do not restrict myself to the details of construction 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.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
