ALBERT KING- BARMOR-E, OF MILANO, TEXAS, ASSIGNOR TO VILLIAI Il. BREVOORT, OF VINCENNES, INDIANA.

WAGON-BRAKE.

SEECIFICATION forming part of Letters Patent No. 325,038, dated August 25, 1885.

Application filed April 30, lSr.

To all whom, t may colte/1711,-

Be it known that I, ALBERT KING vBAR- Monn, a citizen of the United States, residing at Milano, in the county of Milam and State of Texas, have invented certain new and useful Improvements in YVagon-Brakes, of which the following is a description.

Figure l is a side view of the wagon-brake and means for operating it. Fig. 2 is a plan view of the same. Fig. 3 is a side view of a modification in the means for operating the wagon-brake.

This invention relates to brakes for wagons or other vehicles; and it consists in the dctailed construction of the parts hereinafter described, by which the brake is applied to the vehicle-wheel and disengaged therefrom when not required.

In the accompanying drawings, similar letters of reference indicate corresponding parts in all the figures.

A is a ratchet-wheel, pivoted on the shaft c, attached to the frame of a wagon.

I3 is a short barrel, also pivoted on the shaft nl, and made solid with or otherwise i'irinl y secured to the said ratchet-wheel.

C is a bracket for carrying one end of the shaft a, the other end of which is supported in the frame of the wagon.

I) is a lever, pivoted at d to the frame of the wagon, and provided with a brake-block, d, for pressing against one of the wagonwheels.

E is a cord or chain, which is attached to the end of lever D and to the barrel B, so that when the said barrel is rotated the cord will be tightened and the brake-block pressed against the wagon-wheel.

F is a lever, also pivoted freely upon the shaft (l, and provided with a pawl, f, and with a spring, j", for rotating the ratchct-wheel. The pawl j' is also provided with a heel, f2, the use of which will be hereinafter' more fully explained.

G is a catch, pivoted on the pin ,r/ in the framing of the wagon, and provided with a projecting portion, g', and with a spring, g?, which causes the said catch to engage with the teeth of the ratchet-wheel and prevents it from turning backward.

The brakelcvcr is operated. by a few short (No model.)

strokes ofthe lever F, which tighten the cord until the brake block exerts the required pressure, and the catch then holds the brakelever with the brake-block applied to the wagon-wheel. In order to release the brake the lever F should be moved quickly in the opposite direction. rIhis will cause the heel f" of the paw] to strike against the upper end of the catch, and thereby release both the pawl and the catch from contact with the ratehet-wheel. The tension of the cord will cause the ratchet-wheel to turn backward, and the wagon-wheel will be relieved from the pressure of the brake-block.

NVhile the devices before described will give good results, I prefer in connection therewith to employ the striker or guide H, as shown in Fig. 3. This striker may be supported on the wagon-framing, and it is arranged to engage and free the point of the pallet or pawl f from t-he ratchet-wheel when the operating lever is moved to approximately the extremity of its rearward stroke. By this guide or striker the pallet is released from the ratchet- Wheel before its heel strikes the stop paw] or catch G.

The vuse of the striker H will not in any way interfere with the action of the lever in applying the brake.

It will be noticed that the wagon-brakc described above is applicable to all kinds of vehicles, and is simple in action and easily constructed, also, that when the brake is applied in the man ner described the brake-block does not require to be kept so full as is necessary when the power is applied directly to the end of the brake'lever. y

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a wagon-brake, the combination of the lever F, provided with a pawl having the heel f', a ratchet-wheel7 and the catch G, having the projecting portion g', substantially as shown and described.

2. rIhe combination of a brakedever prou vided with a brake-block, the ratehet-whcel A, barrel B, connected by a cord to the brakelever, the lever F, provided with a pawl having the heel f2, and the catch G, substantially as described and shown.

3. The combination of a brake lever and ratchetwheel, of a striker or guide arranged ro block, the ratchet-Wheel A, barrel B, the lever in position to engage and release the point of F, provided with a pawl, f, the striker H, and the pallet ab approximately the extremity of the catch G, substantially as described and the rearward stroke of bhelever,substanially 5 shown. Y as set forth.
