IMPROVEMENT IN WAGON-BRAKES.

Specitication forming` part of Letters Patent No. 175,799, dated April 4, 1876; application filed July 9, 1875.

To all whom it may concer-n Be it known that I, LESTER B. WELCH, of Mount Vernon, in the county of J eft'erson and Territory of Colorado, have invented a new and Improved Wagon-Brake; and I do hereby decla-re the following to be a full and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a side view ot' a wagon-box supplied with my invention. Fig. 2 is also a side view, showing,l the other side ot' the wagonbox. Fig. 3 is the hand-levertbr applying the brake to the rear wheels ot' a wagon, showingl that the whole device can be reversed and adjusted to either side of the wagon.

Similar letters` of reference in the accompanying drawings denote the same parts.

This invention relates to a wagon-brake employing` two cross-bars or double-acting levers whereby a brake-slice is pressed against the front and rear ot' each wheel on the same axle in place of the single cross-bar and brakeshoes that press only on the front of the wheels; and has for its object to provide a more ei'ectual wagonbrake thaf. has bet'ore been used, which shall be simple in construetion, sure and eicient in operation, and that will stop instantly both wheels from turning when the wagon is going down the steepest hill.

To these ends the inventiolr consists in the peculiar construction of the devicev as I will now proceed to describe.

I n the drawings,A represents a wagon-box and B the front cross-bar lowered from the wagon-box so that the brake-shoes b b will press the wheels below the center, thereby having the greater pressure on the wheels. The double joint o o allows the forward and backward movement of the front bar B, at the same time holding it firmly in its properplace below the wagon-box. D is the rear crossbar in position against the bottom of the wagon-box, so that the brake-shoes d d will press the Wheels above the center, thereby having the greater power on the wheels. E is the double-acting lever, as shown in Fig. 1. F is the double-acting lever, as shown in Fig. 2. G is the connecting rod under the wagon, at each end ot' which is fastened the doubleacting levers E and F. H is the hand-lever by which the power is applied. The crossbars B and D are connected with the doubleacting levers E and F by rods a a. and c c. The hand-lever is connected by rod e, as shown in Fig. 1. The cross barsBand D andthe connecting-rod G can be held in proper position by any convenient device, as shown in Figs. l and 2.

To applyr the brake the hand-lever H must be pressed forward, which will draw the rear cross-bar D forward and the front cross-bar B backward. The brake-shoes b b will then press the wheels in front and below the center, while the brake-shoes d d will press the` wheels at the rear and above the center. By this arrangement a very small power at the hand-lever. will stop both wheels from turning, however heavy the load or steep the hill may be. The whole arrangement of parts is simple and the operation is certain and effective.

`l claim as my invention and desire to secure by Letters Patent- The connecting-rod G, double-acting levers E and F, and connecting-rods a a and c c, in combination with the cross-bars B and D, substantially as described.
