VEHICLE-BRAKE.

SPECIFICATION forming part Of Letters Patent NO. 361 ,589, dated April 19, 1887.

Application filed January 27, 1887. Serial No. 225,657. (No model.)

To all whom it may concern:

Beit known that I, JOHN H. IRWIN, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and Improved Vehicle-Brake, of which the following is a full, clear, and exact descrip tion.

The object of my inventionis to provide a new and improved vehiclebrake which is simple and durable in construction and very effective in operation.

The invention consists of the construction and arrangement of various parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings,formingapart of this specificatiom'in which similar letters of reference indicate corresponding parts in both the figures.

Figure l is a sectional side elevation of a vehicle provided with my improvement, and Fig. 2 is a plan view of the same with parts of the vehicle-box bottom broken out.

The vehicle A, of any approved construction, is provided with usual-box, B, havingin the front of its bottorii a slot, B, through which projects the foot-lever O, pivoted to the box B. The lower end of the lever 0 projects a short distance below the bottom of the box B, and to this end is pivoted the horizontal arm D, which extends toward the rear and joins rigidly the vertical arm E, secured to the trans verse rod F, held in the brackets G G on each side of the box B.

The brackets G are each provided with the horizontal elongated slot G, which permits a lateral motion of the rod F. From each outer end of the latter extends downwardly a brakearm, H, carrying the brake-shoes I, of any approved construction, and held in close proximity to the hind vehicle-wheels.

\Vhen the operator desires to apply the brake, he presses with his foot against the footlever O in the direction of the arrow a,whereby the brake-arms D E, the rod F, the arms H, and the shoes I are moved toward the rear, .thusbrin'ging the shoes I in contact with the rims of the hind wheels. The rod F has a free lateral movement in. the elongatedslots G of the brackets G.

The spring K is compressed by the rearward motion of the brake-arms, and when the operator-releasesthe pressure on the foot-lever O the spring K will force the several parts to their former positions, thus disengaging the brake-shoes I from the rims of the hind vertical arm E, rigidly jointed to the said arm D, the rod F, carrying the said arm E and mounted in the said brackets G, and the downwardly-extending arms H, fastened on the said arms F and supporting the brake-shoes I, substantially as shown and described.

2. In a vehicle-brake, the vehicle-box B, the hangers G, secured on the said box B, and the spring K, in combination with the foot-lever C, pivoted on the said box B, the arm D, pivotally connected with the said foot-lever O, and having the angular arm E, the rod F, having its bearing in the said brackets G and carrying the said arm E, the downwardly-projecting arms H, secured to the and F, the brakeshoes I, secured on the said arms H, and the steps J, fastened on the said arms H, substantially as shown and described.
