WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent No. 260,992, dated July 11, 1882,

Application tiled May 5, 1882. (No model.)

To all 'whom it may concern:

Beit known thatI, WILLIAM J. KEER, of White Oak Grove, in the county of Greene and State of Missouri, have invented certain new and useful Improvements in Wagon-Brakes; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification, in which- Figure l is a perspective view of my wagonbrake attached to a wagon, and Fig. 2 is a detail perspective.

This invention relates to wagon-brakes; and the nature of my invention will he fully understood from the following description when taken in connection with the annexed drawings.

The letter A designates the side-board of a wagon-bed, yto which 1 rigidly apply my improved brake.

C designates a segment, the upper edge of which is toothed, as indicated at a. The ends of this segment are bent square to form the portions b, and these portions are again bent square to form the offsets c c. The front oft'- set receives through it a bolt, d, which passes through the segment and the angular lip, and also through the side-board of the wagon-bed.

A singlenut holds this front end of the toothed segment rigidly to its place. The rear oiiset receives through it a bolt, d', which passes through the segment and a plate, O', and also through the side-board of the Wagon-bed. A single bolt also holds the rear end of the segment with this additional security. The metal of which the segment C is formed is bent to form the plate C', which is a bracenot only for the front bolt, d, but also for the rear bolt, d. This plate or brace C is extended downward, and its end is angularly bent twice on itself, to form what I shall denominate a stirrup, O2, through which passes a bolt, d2, that secures this end of the brace C to the sideboard of the wagon.

It will be seen that the toothed segment, its angular ends or offsets, the curved brace, and its stirrups or angular end are all formed of one piece of metal.

D designates a hand-lever, which is pivoted to the bolt d2, and which is connected to the brakes by a rod, F. This leverD is bent outwardly, so that it will lieclosely against the inner side of the segment C, as shown in the drawings.

E designates an angular strap or loop of metal, which is rigidly riveted to the outer side of the lever D, and which receives through it the toothed segment O. This loop E braces the lever against lateral motion, but allows it free vibration about its fulcrum-bolt d2.

G designates a lever, which has formed on its lower'end a pawl, G', that passes freely through and is allowed vertical play in the loop E above the serrated edge of the segment C. The beveled or engaging part g of the pawl G isA made very broad, so that a shoulder, h, is formed on it adapted to bear against the rear edge ofthe lever D, and when the brakes are applied to assist in resisting the strain on the beveled or engaging edge or end of pawl G.

The lever G is connected by links JJ to the hand-lever D, and these links are so pivoted to the said levers that the pawl-lever G will, by its own gravity, engage with the toothed segment when freed from the grasp of the hand. The Lipper' partofthe gravitating pawllever G is in such close relation to the corresponding part of the hand-lever D that it is convenient for the driver to grasp both levers in one hand at the same time.

It is lclear from what I have above described that when the handles of the two levers D and G are grasped and pressed together, the pawl G will be freed from the segment() and the brakes can he released, or, in other Words, the levers can be vibrated freely. When the lever Gis released from the grasp of the hand the weight or gravity of this pawl-lever will cause an engagement of it with the segment C without the use of a spring or other auxil- Iary.

Having described my invention, I claim as new- The combination of the gravitating lever' G, the pawl G', and the shoulder formed on this lever with the vibrating hand-lever D, the loop E, the links J, and the toothed segment, substantially in the manner' and for the purpose described.

In testimony that I claim the foregoing as my own I afx my signature in presence of two witnesses.
