Description
UNITED STATES SAMUEL H. MILLER, OF CANTON, MISSOURI, ASSIGNOR OF ONE-HALF HIS PATENT QFFIGE.
RIGHT TO JOSEPH T. LEMLEY AND ROBERT D. LEMLEY, OF QUINCY, ILL.
IMPROVEMENT IN WAGON-BRAKE LOCKS.
Specification forming part of Letters Patent No. 189,052, dated April 3, 1877; application filed July 29, 1876.
To all whom it may concern Be it known that I, SAMUEL H. MILLER, of Canton, Missouri, have invented a new and useful Improvement in Wagon-Brakes, which is made substantially as set forth hereinafter, referring to the accompanying drawings, in Which Figure I is a side view of the improved parts. Fig. II is a section of same on line W of Fig. I. Fig. III is a detail of a portion of same.
This invention is a device for operating and locking wagon-brakes, having improved features.
The apparatus is made of metal, substantially as shown, to be attached to the side of the Wagon-bed, in the usual position, by bolts through the part A at B B. The part A has a pivot for lever G at the end of shank O. The shank O is connected with rack E at one end, and is arranged so the rack will stand out from the bed while the shank rests against it. The rack-bar has a smooth face on one side, and a rack with teeth pointed backward on the other side, turned from the wagon-bed. It is curved, with the pivot of lever G as its center point. The whip-socket D is connected with the rack at one end, so that the whip may be dropped in it as the brake is operated. It is formed by the metal of the part A having a projection, hollow on one side, arranged to rest against the wagon-bed, and leave with that a suitable cavity for the purpose.
The lever G is pivoted to part A at one end, and has a hand-hold, H, for operating it at the other. It bears a latch, F, fixed on it, arranged to engage with the rack E on the outside, and a pivot-eye, L, projecting outwardly for the brake-rod S, arranged so the brakerod will pull the latch into the teeth of the rack. The lever G also has a part bearing on the opposite side of the rack E, at some distance behind the bearing-points of the latch and pivot-eye, arranged so that the brake-rod eye L and this hearing on the rack will form a leverage to force the latchpoints into the the rack.
The rack E has at its back end a wedge, T, arranged so that the lever G will be wedged tight when resting back out of use,,to prevent noise of rattling.
The brake-rod S screws into a block at its end, like a nut. This block bears a hook, S, which engages with the eye L. These are arranged so the rod can be shortened up and adjusted by turning this block on the screw threads as the brake wears 0d, 860.
I claim- 1. In a wagon-brake, the lever G, having the handle H and loose pivot I, the latch F, and angular projecting eye L, in combination with the curved rack E and brake-rod S, arranged substantially as set forth.
2. In combination with the brake-rod S and curved rack E, the loose-pivoted lever G, having the latch F and the bearing part on opposite sides of the rack-bar, arranged so the latch may be engaged or disengaged from the rack by twisting the handle H, substantially as set forth.
3. The combination of the brake-rod S, the screw-block having the hook S, and the latchlever G, with eye L, arranged for use substantially as set forth.
SAMUEL H. MILLER.
