To all whom it mlay concern;-

Be it known that I,'TH0MAs W. Frren, J r., a citizen of the United States of America, re-* siding at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Track- Brakes; and I hereby 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 pertains to make-and use the same.

This invention relates to an improved track-brake which is supported and arranged adjacent to therail of a track for the purpose of arresting a car or vehicle moving upon and along the said track by exerting ressure against both faces of, and thereby c amping the wheels which engage, the said rail.

e To the end of providing a simple and effective brake of thecharacter indicated and to realize other advantages hereinafter appearing this invention-consists in certain features of construction and combinations of parts hereinafter described, and pointed out in the claims. I

In the accompan ing drawings, Figu're 1 is a top plan of one oflthe rails'of a track upon and along which cars or vehicles are ril'evedand illustrates the forward wheel of a car in position to further segarate the pressure-exerting or clamping brake. Fi 2 is a side elevation in section on line 2 2fi ig. 1, lookin in the direction indicated by the arrow. ig. 3 is a transverse vertical section on any one of lines 3 3, Fig. 2, looking in the direction indicated by the arrow. F1 4 is a transverse vertical sec-' tion correspon ingwith Fig. 3, except that in Fig. 4 the clamping-bars are shown actuated laterally and outwardly against the action of means acting to retain the said bars in their inner and normal position.

Referring to the drawings, A represents a rail of a track, and B a sleeper instrumental in supporting the said rail and arranged next below and longitudinally of the rail.

D indicates a portion of the wheel of a car mounted on the track comprising therail A, and G two"'pressure-exerting or clamping bars adapted to exert pressure against oppo-. site faces, respectively, of the W eels at one ars of my improved .-ranged transversel and the same side of the car, which bars are arranged, therefore, asuitable distance above,

but at opposite sides of, the rail. The barsG extend longitudinally ofthe rail Aa suitable distance. Each bar G 'isfrovided at its uper longitudinal edge an externally with a aterally and outwardly projecting flange g,

Which extends from end to end 0 and reinforces the bar. The bars G are movable laterally-that is, the bars G are relatively movable to Widen the space between them, because the said bars are normally spaced apart somewhat less than the thickness of the wheels which are to be clamped by and between the said bars. Means acting to retain the bars G in their inner and normal position are pro- ;vid'ed, and the said bars curve laterally and outwardly at their ends, as at Gthat is, the

end portions of thebars G diverge toward the outer extremities 'ofthe said end portions to accommodate the passa e between the bars of the forward wheel of the wheels at one and the same side of the car and to accommodate the movement of the-said bars laterally and outwardly by the said forward wheel against the action of the means acting to retain the bars in their normal position upon the travel of the said wheel between and along the said bars. Preferably several upright lever-forming bars K are arran ed at the outer side of each bar G and equidistantly longitudinally of the last-mentioned bar. Each upright lever-forming bar K is secured at its upper end in any approved inanner to the adjacent clamping-bar G and extends downwardly from the said clamping member to and transverselyof the adjacent side of the sleeper B and is loosely mounted at its lower end upon a bolt L, which is arranged horizontally and at a right angle to the sleeper and extends laterally throu h and transversely of the lower portion 0% the sleeper. It will beobserved, therefore, that several parallel bolts L are'supported from the sleeper B and arof and equidistantly spaced longitudina ly of the sleeper. The bolts L project a suitable distance beyond op osite sides of the sleeper B, and each bolt L ears a pair of lever-forming bars K, which are loosely mounted on the bolt at op osite, sides, respectively, of the sleeper, an each I 5 outer side of one of the washers bar K is arranged betweenapair of washers J, which are loosely mounted on the said bolt, with the inner washer of each pair of washers arranged next adjacent the adjacent side of the sleeper, with the outer washer of one of the pairs of washers J interposed between the outer side of one of the bars K and the head 1, with which the bolt is provided, and

with the outerwasher of the other pair of wash- 1 ers J interposed between the outer side of the other of the said bars and a nut e mounted on the shank of the bolt. In other words, each bolt L between the washers of each pair of washers J extends loosely through holes 7c,

I5 formed in the lower ends of the bars K,

mounted on the said bolt to render the said bars ca able of being swun outwardly to widen t espace between the clampin -bars G, and the pair of bars K, supported om the 2 said bolt, are arranged at opposite sides, re-

spectively, of the sleeper.

The opposin faces or sides of the washers of each pair 0 washers J recede from each other outwardly from the bolt u on which the said washers are mounted to t e edges of the washers to render the lever-forming bars K free to swing laterally, and the sleeper B constitutes means for limiting the movement of the clamping-bars G inwardly or toward 3 each other, and the holes is in the bars K on each bolt L are large enou h to freely accommodate the said swinging o the said bars laterally. At an suitable point between each ho t L and t e clamping-bars G is provided 3 5 another bolt R, which extends loosely throu h the lever-forming bars K, mounted on t 1e aforesaid bolt L. The bolts L and R are parallel, and the bolts R extend beyond the outer sides of the lever-formin bars K. The

4 bolts R are shown extending t ough slots 0/ in the rail A. Two washers Q are loosely mounted upon each bolt R at the outer side of the op osite bars K, respectively connected with t e said bolt, and the op osing faces or sides of the said washers rece e from each their inner and normal osition.

Obviously the forwar car-wheel, which, as shown in Fi 1, comes into engagement with the inner si es of adjacent diverging ends of the clamping-bars G, actuates the said bars during the movement of the said wheel into the space between the said bars against the action of the springs h, confined on the bolts R.

By the construction hereinbefore described it will be observed that the wheels at one and 5 3 the same side of the car when they are in pobars arranged above and longitudinall sition between the two pressure-exertin or clamping bars G are effectually clampe by and between the said bars.
