WAGON BRAKE.

No. 381,413. Patented Apr. 17, 1888.

UNITED STATES PATENT OFFICE.

EDMUND A. PARKER, OF RUSHVILLE, ILLINOIS.

WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent No. 381,413, dated April 17, 1888.

Application filed April 3, 1886. Serial No. 197,597. (No model.)

To all whom, it may concern:

Be it known that I, EDMUND A. PARKER, a citizen of the United States, residing atRush- Ville, in the county of Schuyler and State of A is lever of first class, fulcrum at B. The

lower part of lever turns under wagon-box, as

shown atk, and is fastened to conneeting-rodI. O is lever of second class pivoting at i, and connected to brake-bars m m, which are levers of first class.

The lever A is provided with pawl e, operated through rod (1 by handle 0. Pawl e catches in ratchet-circle 0, whose teeth run backward instead of forward, as usual in wagonlocks. The lever A when not in use lies forward against the top of standard D, so as to be out of the way in getting into the wagon-box. When the lever is pulled back to the position shown by dotted lines, the brake is set. The

, lever A at its fulcrum is flattened out broadly,

as shown at a, and the ratchet-circleis also very broad and fiat, as shown at b. This prevents the upper part of lever chafing the sideboard, and in combination with inner circle gives the pawl e a firmer grip of the ratchet teeth. The ratchet circle may turn under the box with a square corner, and the rod passed tirely under the box, or said circle may be a plane surface fastened higher up and the rod run back on the outside of box.

I am aware that lock-levers, ratchets, and pawls are used on wagon-locks; but know of none where the lock-lever is of the first class and the power applied by pulling the lever backward.

WVhat I claim as my invention, and desire to secure by Letters Patent of the United States, is

1. In a wagon-brake, the combination of a semicircular ratchet-frame, a handlever placed in and pivoted to said frame having its short arm bent back at right angles and extended v beneath the wagon-box, a lever of the second class secured to the under side of the box, brakelevers connected to the same, and a rod connectingsaidhand-leverand second-class lever, substantially as described.

2. In a wagon-brake, the combination,with the semicircular ratehet-frame,of a hand-lever placed within said frame, having a pawl pivoted thereon and a broad bearingsurface formed near its lower end, its short arm bent back at right angles and extended beneath the box of the wagon, a lever of the second class secured to the bottom of the box, levers having brake-shoes at their outer ends connected to the same in the rear thereof, andarod connected to said handlever and second-class lever, substantially as described.

3. In a brake for wagons, the combination of the ratchet-frame 0, having a broad metallic base, 1", secured to and extending under the wagon-box, a hand-lever, A, pl iced within said ratchet frame having a pawl pivoted theretoengaging with said ratchet, and having a broad bearing, a, secured to broad bearingb on the ratchet-base, a short arm, k, bent at right angles and extended beneath the box, a lever, O, secured to the under side ofthebox, levers m m,located in the rear of and connected to said lever O, and a rod for connecting arm k with lever O, substantially as described.
