-TO ALL WHOM IT MAY CONCERN: I

Bc it known that I, THOMASSMITII, o California,in the county'oi`-Moniteau, and State of Missouri, have invented a new and improved Self-Acting WagonLBrakc; and I do hereby declare theffollowing to be a full, clear, and exact description of the same, sufficient to enable those skilled in the'art to which my invention appertains to make use of it, reference being had to the accompanying drawings, forming' part ot' this specification, and in which- Figure 1 is a side elevation, and i Figure 2 a top view of my invention. l

In this invention the friction-blocks are adjustable in order to accommodate them to dili'crent wheels, and are directly attached to and supported' by the springs of the brake'. The apparatus is also made adjustable to horses of diiercnt sizes. I

In the drawings, A represents the wheels; B, thc axle; C, the tongue; DD, braces attached to strengthen the 4tongue and provide a support 'for th'e brakes; and E a' stout, tint springattached at its middle to a bar, F,

which connects-the rear ends of the braces D D. The spring E is made long enough to extend from wheel to wheel, and to its ends are xed the friction-blocks e e, which are applied to the wheels to retard their motion. These blocks may be either rigidly attached to the springs, or theymay be pivoted to a clasp or slide, G, which is made adjustable along the spring by means of a slot and set-screw, s, to accommodate the block to differentlyconstructed wheels.' The blocks e'e being pivoted to the clasp or slide G, will accommodate themselves to the position ofthe rim against which they operate, A'always presenting their whole length fairly against the wheel.

The spring E, holds the blocks close to but not in contact with the tire ofthe wheel. In order to apply the brake to the wheels, I connect the spring hy rods h 7L, from a point` near each end to a rod, I, which extends the whole length of the tongue, lying under it and sliding longitudinally in sockets i z', provided for tho purpose. The forward end of this r'od I connect with the neck-yoke J by means of a cord `or chain, k, passing over a pulley, m, in the 'end of the tongue. By this means, whenever the neck-yoke is thrown back, as in backing, or holding back when going down-hill, the rod I Ais drawn forward-and the brakes applied. A ring, o', attached to the neck-yoke, passes around the tongue, and rests against a pin, t, when the yoke -is thrown back, for the purpose of backing or holding back'the carriage. This pin may be adjuetedin different positions along tho tongue by means of a series oivholes, 'u v u, providedfor the purposc,in order to accommodate the apparatus to horses oi' different sizes.

The whole devicei'orms the most. simple, durable, and eiective apparatus for the purpose which has yet been brought into use. Itha's been thoroughly tested, and found to bel in every respect superior to the old form of brake. It can be attached at little expense to an)1 hind of, carriage, and its adjnstability gives it a decided advantage over. those brakes which can only be used in connection with axles of the. same length or wheels of the same form.

Having thus described my invention, what I claim as new, and desire to secure by Lettcis Patent, is- 'The self-acting wagon-brake, composed of the block e, pivotcd to the adjustable slide G, which is itself directly attached to the spring E, and operated-by the rods h and I and yoke J, when the parts referred to are constructed as dcscribed, and combined and arranged'iu tho manner and for thapurposes speei'ded.

To the above speciii'cation of m'y improvement I have signed my hand, 'this 16th day of January, 1868.
