Application filed April To all whom it may concern:

Be it knownthat I, CHRIST MiNEAn'r, a citizen of the United East Pleasant Plain, in son and State of Iowa, and useful Car-Brake, ing is a specification.

The invention. relates to improvements in car brakes.

The object of the present invention is to improve the construction of car brakes, and to provide a simple, inexpensive and etiicient car brake of great strength and durability, adapted to be applied to any ordinary truck, and equipped with means for preventing the brake beams from dropping down upon the rails.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafterfully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion size and minor details of construction, within the scope of the claim, may to without departing from thespirit or sacrificing any of the advantages of the invention. i

In the drawings :-Figure 1 is a central the county of Jefferhave invented a new of which the follow.

vertical longitudinal sectional View of a car truck, equipped with a brake, constructed in accordance with this invention. Fig. 2 is a plan view of the same. Fig. 3 is a reverse plan view. Fig. 4; is a vertical sectional view taken on the line l-& of Fig. 2, and illustrating the arrangement of theguards.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

In the accompanying drawings in which is illustrated the preferred embodiment of the invention, 1-1 designate inside brake beams of the truss type, suspended by suitable hangers 2 from the upper portion of the truck at opposite sides of the bolster 3 thereof, and operating in the space bet-ween the spring plank lirnd'the car wheels 5.

The brake beams are supported above the lane of the lower face of the spring plank and prevented from dropping below the same by means of approximately horizontal guards 6, extending across the lower face of the spring plank and projecting out \vardly beyond the side edges thereof and having their projecting portlons arranged Specification of Letters Patent.

beneath the brake beams The guards (3,

which are located at opposite sides of the truck, consisting of bars or pieces of channeled metal, or other suitable material, and they are secured to the spring plank by vertical bolts 7, piercing the spring plank and the guards and having nuts 8 arranged between the side flanges 9 of the guards. The side flanges of the guards depend from the same, and the upper faces of the guards are flat between the terminals 10', which are extended upward slightly.

The guards besides preventing the brake beams from dropping upon the rails enable them to be arranged in a position, which will admit ofv the employment of a relatively straight inclined connecting bar 11 having a slight bend .12 near its lower end, and connected at its upper end 13 with an upright lever 14. The connecting rod and the lever are arranged centrally ofthe truck, and the red extends through the space between the spring plank and the bolster, and its downwardly extending terminal portion is pivoted by a bolt 15, or other suitable fastening devicein the central strut member 16 The lower endof the uprightlever 14 is pivoted by a bolt 16, or other suitable fastening device in the bifurcation of'the strut member of the other brake beam, and the end13 of the con necting rod is forked or bifurcated-to receive the lever 14, and is providedwith a plurality of perforations 17 for the recep tion of a bolt 18, or other suitable fastening device to afford an adjustable connection between the brake beams.

The upper end of the upright lever it is connected by a rod 19 with the brake operating mechanism, end of the lever ll is moved toward the bolster of the truck, the brake shoes 20 of both the brake beams are carried into en gagement with the car wheels. Owing to the particular arrangement of the brake beams, a' connecting rod 11 of great strength and when the said upperstrain ma be employed. as the rod 11 is straight ti roughout the major portion of its length and at one end.

What is claimed is The combination, with a car truck, of brake beams located at opposite sides of the spring plank and'arrangedabove the plane of the lower face of the same and operating has only a slight curvature between the spring plank and the cur Wheels, being straight from the bend to its other 10 an upright le er connected at its lower end, end. v
