REUBEN HURD, or MORRISON, ILLINYQISQ Letters Patent No. 102,009, dated April 19, 187i).

mrnovnmnu'r m WAGON-BRAKES The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, REUBEN Hum), of Morrison, in the county of Whit'eside and Stateof Illinois, have invented an Improvement in Wagon-Brakes; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings andto the letters of reference marked thereon.

Drawings. Figure l is a side elevation of a portion of a wagon having my improvement attached thereto; Figure 2 is a plan view, showing the arrangement of the parts and the manner of applying the brakeblocks to the wheels;

and in the means for applying the same to the wheels with the usual serrated bar or rack, B, for keeping the lever in any desired position.

0 refers to a connecting-rod, which extends from lever B to-and connects with a lever placed upon the under side of the wagon bottom.

D refers to the lever above alluded to, it being pivoted as shown in fig. 2, its inner end extending inward to or about to the center of the wagon-body.

E refers to a link, which connects the lever D to a sleeve which slides upon a rod extendingfrom the rear axle to the cross-bar to which the brake-blocks are attached.

F refers to a sleeve, which is made to fit and move upon the roll above alluded to, its rear end being provided with slotted projections, and its front end with'a single one, to which to attach the connectinglink E.

- F Frefer to links, the inner ends of which enter the slots in sleeve 'F, to which they are pivoted.- From thispoint they extend outward at a considerable angle to and connect with levers F F, the rear ends of which are pivoted to the rear axle, while their front ends are pivoted to wedges which'slide in guides attached to the cross-beam which supports the brake-blocks.

G G refer to the wedges alluded to, their inner ends being slotted to receive the ends of levers 13 F, by which they are operated.

H refers to a brake-block, of which there are two, one for each hind or rear wheel of the vehicle.

The form of this block is clearly shown in figs. 3, 4, and 5 of the drawings, the beveled portion thereof,

which is designed to come in contact with the wheel,

being covered with leather, wood, or any other suitable material.

Upon the rear side of that portion of the block just described there is a projection, which has, in a recess formed therein, an anti-friction roller, E, that portion which is inside of such recess serving as an abutment-for the end of the wedge to come in contact with, as shown in fig. 5. i

From .the upper and lower surfaces of this projection ears project, through which pass bolts which attach the block to the guide G, as shown in fig. 2.

H refers to the roller, which is arranged vertically within a recess in the outer surface of the brakeblock, and so that when the blockis in contact with the wheel, as shown in full lines in fig. 2, the wedge G shall come in contact with such roller, and thus relieve the friction consequent upon forcing the wedge against the brake-block.

H refers to a spring which is coiled around the bolt, which secures the block to the cross-bars, and so arrangedthat, as the block is pressed against the wheel, the tension of the spring is increased, and

when the wedge is withdrawn the block will be thrown back into the position shown in dotted linesv The operation of this device is as follows:

The parts having been constructed and arranged as shown, the driver or operator presses upon the upper end of the-lever B, carrying it forward, its motion being communicated to the sleeve F, carrying it forward upon the rod on which it slides, and then carrying out-ward the forward ends of levers F F, and

with them the wedges G G, the result being the pressing of the brake-blocks upon the wheels with "great force, consequent upon the leverage afi'orded by the tcggle-like joint caused by the arrangement of the links F F and levers F F.

Having thus described my invention,

What I claim and desire to secure by Letters Patcut, is r 1. The method herein-described of applying brake blocks to the wheels of vehicles, the means employed being a toggle-joint acting upona wedge, substan In testimony whereof I have hereunto signed my tially as and for the purpose set forth. name to this specification this 12th day of March,

2. The construction of the brake-block H, substan- 1870, at the city of \Vashington, in the District of tially as and for the purpose set forth;

3. The combination of the brake block H, the wedge G, levers F links F, slee ml, and the rod upon which Witnesses: said sleeve slides, substantially as and for the purpose JOSEPH R. EDSON,

specified. O; F. CLAUSEN.

Columbia, in the presence of two attesting witnesses.

REUBEN HURD.
