IV. D. IVILLIAMS, OF RALEIGH. NORTH CAROLINA.

WAGON-BRAKE.

Specification of Letters Patent No.

To all whom it may concern:

Be it known that I, IN. D. VILLIAMS, of Raleigh, in the county of ake and State of North Carolina, have invented certain new and useful Improvements in agom' Brakes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1, is a plan of the same as it appears when the brake is not in operation. Fig. 2, is a longitudinal section of the same through the line w, m, in Fig. 1.

Similar letters of reference in each of the several figures indicate corresponding parts.

A, A, represent the axles which are united together and braced in the ordinary manner and have the wheels B, B, B, B, secured on their outer ends.

C, C, are iron clamps placed around the front axle A, in the manner shown, in Fig. 2; these clamps have projecting ears or eye pieces a, a, cast on their front side, to which the swinging links Z), 6, are connected by means of the pins (3, which pass horizontally through them and the eyes of the pieces a, a, and form swinging or rolling joints. On these pins the links 7), are allowed to turn freely. These links 6, b, serve to connect the the front hounds D, D, of the wagon to the axle or the clamps O, C, of the same, the pins (Z, (Z, passing through the front ends of the links and through the back ends of the hounds in the manner shown in F 1, and 2, thereby forming another hinged or rolling joint. Thus it will be seen that double swinging or rolling joints are formed between the front hounds D, D, and the front axle A, the object of which will be stated shortly. The hounds D, D, are fastened tightly to the sides of the reach E. and to the cross piece F; in which the back end of the reach E, is secured. On top this reach. a short distance from the front axle, is placed a stout cross piece G, which extends nearly the whole width of the wagon and is secured at its center to the reach by a bolt as shown in Fig. 1, and braced near each end by the rods or bars 6, e, which connect it with the crosspiece F, as shown in Fig. 1. On each end of the cross piece G, is a metal bearing f, f, to which the projecting arms or pieces 9, g, of the bar I which carries the brakes h, h, are secured and allowed to turn freely these hearings being the center upon 10,218, dated November 8, 1853.

which the brake turns as it is thrown from the back to the front of the reach E, when it is desired to dump the load.

By making or forming double swinging or rolling joints H, H, between the front axle and hounds as seen in Figs. 1, and 2, I am enabled to render the brake perfectly self acting with the aid of the horse, drawing the wagon, for it will be seen by examining Figs. 1, 2, (in black lines), that if the horse is traveling on a level surface the brakes will be always disengaged from the wheels at which time as is well known it is not required or desired that they should operate, but that if the horse should be traveling down an incline plane and the wagon consequently caused to have a greater momentum than the speed of the horse the brakes will be instantaneously applied to the wheels, or are made to assume the position shown in red lines in Fig. 2, thereby preventing too great and sudden weight coming on to the horse, also avoiding the serious consequences arising from the use of a greater proportion of the brakes now in common use and likewise saving the time and trouble of applying or disengaging the brakes by hand, for as soon as the horse reaches the level surface he instantaneously draws the brakes off the wheels again.

In Fig. 2 of the drawing will be seen the manner in which the brake is thrown to the front of the reach E, when it is desired to back the horse; the dotted lines in said fig ure indicating its position when thus thrown back. This is necessary in case it is desired to dump the load, and therefore it is important. In other brakes this di'fliculty is most generally experienced. This simple contrivance very effectually obviates any such difliculty of not being able to back the wagon, and is very easily operated, it swinging on a center or bearings, and can be thrown back and forth with great ease and despatch.

I do not claim a double crank attached to the front hounds of the wagon and connected to the brakes behind the wheels for applying the power through the action of the horse, forward and backward; but

hat I do claim as my invention and desire to secure by Letters Patent, is

1. Forming two swinging or rollingjoints between the front axle A, and the front hounds D, D, in combination with the swinging brake I, h. h, g, g, arranged on top the of swinging on a center so that it may be 1ethrown over toward the front of the reach When it is desired to dump the load, and

again thrown to its proper place after dumping as herein fully set forth.
