IMPROVEMENT IN WAGON BRAKE.

TO ALL WHOM IT MAY CONCERN:

Be it known that We, D. J. KIIQQMAN and E. H. GRAY, of Winchester, Scott county, Illinois, have invented certain new and useful improvements in Brakes for lNagons; and we hereby declare that the following is a true, full, and exactdescription of the same, reference being had to the accompanying drawings, and t0 the letters of reference marked thereon.

Figure 1, in the drawings, which make a part of this specification, represents a. side elevation of a twowheel vehicle with the brake attached.

The letter A designates the body, and B. the wheels. 0 represents a metal bar occupying nearly a vertical position on the outer side of body A and near its front end. Near the bottom of the body A is the stirrup e, which is securely fastened to the said body. The stirrup e is intended as a guide or support for the metal bar C, which is provided with two projections at its opposite edges. The stirrupe is furnished with a pulley, y, (in dotted lines,) the ofiice of which will be hereinafter described. The lower end of bar 0 extends below the bottom of the wagon, and is-perforated to receive the two metal rods in, which cross each other, and at their opposite ends are hooked in the eyes t on the brake bar On each end of the bar S is fastened the block E..

The bar S is kept in position by the cleats M and the metal strap 2', which is passed under the bar S, and securely fastened at its ends to clean; F represents a serrated metal plate, the ends of which are fastened to the body A, near the front end of A. The serrated edge of F is placed on its inner side, and sufl-lciently removed from the wagon body A to admit of the free play of the bar C, which operates in the space between the plate F and the side of A.

In operating my machine, when it is desired to apply the brake to arrest the motion of the wheels, the bar 0 will be pushedforward, and by the action of the rod is the bar S will be moved towards the wheels so that the blocks at each end of S will press against them and retard or-arrest their motion at the option of the operator. In order to relieve the wheels from the pressure of the brake, the bar 0 will be drawn back to vertical position, and then suffered to fall until the lower projection on bar C and strikes against the pulley g, which, with arevolving motion, throws the upper projection on bar C against the opposite side of stirrup e, where it is caught and held firmly, while the upper end of bar C will out against one of the teeth in plate F.

Having thus described our invention, what we claim and desire to secure by Letters Patent, is- The bar C, in combination with the serrated plate F, stirrup e, the rods K K, the cleat M, furnished with strap 2', and the bar S, the whole constructed and arranged and operating as and for the purpose herein set forth. I In testimony that we claim the foregoing as our own, we hereby aliix our signatures in the presence of two witnesses.
