Description

TES
I rren JAMES B. SEXTON, OF PELLA, IOWA.
IMPROVEMENT IN WAGON-BRAKE LEVERS.
Specification forming part of Letters Patent No. 178,805, dated June 13, 1876; application filed April 8, 1876.
To all whom it may concern:
Be it knownthat I, JAMES B. SEXTON, of Iella', in the county of Marion and State of Iowa, have invented a new and valuable Improvement in Wagon-Brakes and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being bad to the annexed drawings, making a part of this specification, and to theletters and figures of reference marked thereon.
The figure of the drawing is a representation of a plan view of my wagon-brake.
This invention has relation to wagon-brakes and the nature of my invention consists in a segmental bracket, which is toothed on its lower edge, and secured rigidly to one side of a wagon-body, in combination with a brakelcver and a gravitating-pawl, which latter is connected, by a rod, to a handleve'r on the main brake-lever, as will be hereinafter explained. 4
In the annexed drawings, A designates one side of a wagonbody, and B a toothed segment, which has its teeth on the lower edge. This segment is formed on a frame, B, and is set off from the side of the body a short distance.- O designates a brake-lever, which has its fulcrum at a on the frame B, and which extends above the wagon-body far enough to be conveniently handled by the driver sitting in his seat.
Above the fulcrum-pin a a brake-rod, D, is pivoted by a removable pin, 0, which rod has a number of holes through it for receiving the pin 0, and allowing for wear of the brake-shoes. G designates a loaded pawl, which is pivoted to the lower end of the brakedever (J, so that it will engage with the teeth of the segment B, and hold the brake-shoes in any desired position. J designates a rod, which attaches the loaded end of the pawl G to a hand-lever, N, pivoted to the brake-lever G near the upper end thereof. By means of this lever N and its rod J the driver can release the pawl G from its toothed segment, and when released thebrake-shoes can be operated by vibrating the lever G. I
What I claim as new, and desire to secure by Letters Patent, is-
The segmental bracket B B, having teeth on its lower edge, in combination with the gravitating-pawl G, rod J, levers U N, and brake-rod I), all arranged substantially as described.
In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
JAMES B. SEXTON.
