MILTON SATTERL'EE OF FORES-TON, ILLINOIS.

Leite rs Patent No. 95,384, dated September 28, 1869.

IMPROVEMENT IN WAGON-BRAKE.

The Schedule referred to in these Letters Patent and making part of thesamer To all whom it may concern Be it known that I, MILTON Surname, of Foreston, in the county of Ogle, and State of Illinois, have invented a new'and improved Wagon-Brake; 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 had to the accordpanying drawings, making a part of this specification, in which- Figure 1 is a side view.

Figure 2 is a section through line a: x of fig. 1.

Figure 3 is a longitudinal vertical section of the This invention relates to that'class of wagon-brakes in which a lever is employed to throw a shoe or drag under one or both of the hind wheels, or remove it therefrom; and

My improvement consists in a peculiar construction of such shoe, whereby it not only better adapts itself to the inequalities of the ground, but also prevents the sliding or sluing of the wagon on ice or other smooth surface. Besides this, the whole brake-apparatus is entirely disconnected from the wagon-body or box, so that, however it may be strained or wrenched, no injury can result therefrom to the body of the carriage.

1n the drawings- A is a rock-shaft, mounted in stout bearings, B 13, supported by and attached to the rear axle and rear end of the reach.

D is a standard,'supported by a horizontal arm, extending laterally from the reach, and also by two strofig metallic braces, d (l, whichrun back to the block B.

To the upper end of the standard Dis attached a curved beam or plate, I), having suitable stops, e e,

' fixed to it, by which to hold the brake-handle or lever in any required position; and

E is-a curved arm, attached to the shaft A, and supporting the brake-head or shoe G, as shown in fig." l. I

The arm E, it will be observed, extends downward and backward to a certain distance from the shaft A,

then curves'gently upward, then downward again and forward in a curved line, as seen clearly in fig. 1, thus having a curve at e, which, when the arm is thrown back, fits against the convex surface of the hub, and operates at that point as a common hub-brake,.while, at the same time, the general shape of the arm is such as to adapt it not only to this oflice, but also to the more important function of supporting and applying the shoe G. It may hestrengthened by a brace or cord, H, arranged asshown in fig. 1.-

The-arm thus constructed is swung on, or with its supporting-shaft or fulcrum, by means of a hand-lever, L; to which it is connected by a stout rod or chain,F

All these parts are made very strong and durable, and their supports are attached to the frame of the carriage (the rear axle, reach, &c.,) in a substantial manner, so that when the rear wheel is riding on the shoe,

the rod F, lever L, and their supports, will be abunging-plate, O, joined to or upon theshaft m, as shown in fig. 3, and having side flanges, between which the rear wheel XV rides upon it; a middle block or plate, P, articulated to the lower end of arm. E, as'shown at p, and likewise articulated to the shaft an, between the hinges or lugs by which plate Ois thereto 'connected, thus forming a kind of knuckle -joint with plate 0, and having also a spur or stop, p', which extends under the plate 0, and prevents the plate P from being turned back on its pivot, with relation to plate 0, any further than is shown in figs. 1 and 3.

In connection with-these parts is a third plate, Q,

which may be articulated to plate 1, by means of the closely to a rounded projection, r, on the under side of plate P, as seen in fig. 3. The rear end of plate Q, at q, extends back under plate P, forming a stop of analogous construction and use to that described at p in connection with the middle plate.

The shoe G is thus composed essentially of the three (more or less) plates, 0 P Q, articulated to each other, and provided with suitable stops "to prevent flexibility only in one direction, and employed in connection with the supporting-wheels a n, and their axle on. I do not wish to limit myself toany precise detail as to the shape and position of the stops, or the method of joining the several plates together, still less to the exact shape of the plates themselves, my invention consisting rather in the use of articulated plates to form a shoe, and the use of the spur-wheels to partly support the weight of the shoe,-as described, than in the mere details of construction alluded to. The front plate, however, should be made inclined upward and forward at its front edge, so as 'to ride easily over the ground, and the rear plate should be so shaped that the wheel can easily mount and securely ride it, when the lever is thrown forward, as seen in fi .1.

The general operation of the device is as follows:

Upon throwing the handle of the lever forward, the

arm E is forced back, applying the brake e to the hub, and at the same instant dropping the shoe G under the wheel, which at once mounts upon it. The great power necessary to keep the shoe in position is obtained by the' leverage between the hub and the fulcrum A, and also by the draught upon rod F. The

shoe, when thrown down under the wheel, rests partly upon the spur-wheels a n, which are forced into ice, or any other smooth, hard surface, and thus prevent the wagon from sliding or sluing, laterally r At the same time the weight of the earriageis sustained upon the plates 0 P Q, which rest upon the ground, like the ordinary shoe.

If the front end of the shoe strikes a slight obstacle, the shoe does not force through it, but bends upward and passes over it. The shoe cannot very well rest solely upon any one point at any time, but will rest upon the three plates, or, at the; least, upon two of them.

v Having thus described my invention.

What I claini aspen, and desire to secure by Letters Patent, is-- 1. A shoe for wagons, composed of two or more plates, P, Q, &c., joined together substantially as and for the purposes specified.

2. In connection with a shoe constructed of two or more joined plates, the spur-wheels n 11, applied in the manner and for the purpose set forth.'

3. The coinbinationof hub-brake 0' with a shoe, G, by means of a curved supporting-arm E, substantially as and for the purposes set forth.

4. The arrangement of the lever L, supports B D D, shaft A, rod or chain F, arm E, and shoe G, when the several parts are constructed and applied in connect-ion with each other, substantially as and for the purposes set forth.

To the above specification of my improvement I have set my hand, this 31st day of July, 1869.

MILTON SATTERLEE.
