AUTOMATIC VEHICLE-"BRAKE;

SPECIFICATION forming part of Letters Patent No. 317,846, dated May 12, 1885.

Applicationv filed July 5, 1884. (No model.)

To all whom it. may concern.-

Be it known that I, RICHARD H. PACE, of Lineville, in the county of Clay and State of Alabama, have invented a new and Improved Automatic VehicleBrake, of which the fol- 1 lowing is a full, clear, and exact description.

My invention relates to improvements in brakes for vehicles; and it consists in the peculiar construction and arrangement of parts, as hereinafter fully described, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of the front of a vehicle provided with my improved brake. Fig. 2 is a side view of the same, parts being in section. Fig. 3 is a plan view of a two-horse vehicle provided with my improved brake.

The shafts or thills A are united by a crossbar, 13, on which the single-tree O is pivoted.

On the under side of the cross-bar 13 two bracket-arms, D, are secured, which project from the outer sides of the thills, and are also secured to the bottom edges of the thills.

On the outer end of each arm D a lever,

E, is pivoted, on the outer end of which lever standards F are held, on which a brake-shoe, I, is held to slide vertically, the said brakeshoe being provided with apertured lugs G, through which a bolt, H, is passed, having eyes on the ends to receive the standards F, on which it slides.

A rod, J, connects the inner end of each lever E with the upper end of a clip, K, pivoted on the inner side of the corresponding thill.

The traces L are connected with the opposite ends of the single-tree O, and straps, chains, or ropes M connect the lower ends of the clips K with the traces. The holdbackstraps N of the harness are connected with the lower ends of the clips K. Then the horse pulls on the traces L, the lower ends of the clips K are swung to the front and their upper ends to the rear, whereby the rods J are moved toward the rear, thereby moving the inner ends of the levers E toward the rear end, swinging the brake-shoes from the wheels 0.

\Vhen the horse pulls back or holds back, as in going downhill, or when the vehicle is to be stopped, the holdback-straps N pull the lower ends of the levers E toward the rear and swing the upper ends of the same toward the front, thereby pulling the inner ends of the levers E to the front and the outer ends to the rear, whereby the brakeshoes I are pressed against the wheels. The pressure of the brakeshoes against the wheels increases with the strain on the pullbackstraps.

In the vehicle for two horses the levers e, holding the brake-shoes, are pivoted on the ends of the cross-beam d, and from the inner ends of the levers e an iron rod or bar, m, ex-

tends to the neck-yoke n on the front end of the pole 0.

The outer ends of the levers e are connected by chains or straps or like devices with the single-trees. lVhen the horses pull on the chains or straps, they pull the outer ends of the levers a to the front, thus keeping the brake'shoes from the wheels. NVhen the horses pull back: or hold back, as in going downhill, 850., they pull on the strap or rope m, thereby pulling the inner ends of the levers e to. the front and pressing the brakeshoes against the wheels.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with levers pivoted on the cross-piece'of the thills, of hinged and sliding brake-shoes on the outer ends of said levers, clips pivoted to the thills, a rod connecting the brake-levers with the clips, and straps connecting the traces and pullbackstraps with the clips, substantially as herein shown and described.

2. The combination, with levers pivoted on the cross-piece of the thills or pole, and intermediate mechanism for connecting the said levers with the pullback-straps of the harness, of brake-shoes hinged to vertically-sliding' supports on the outer ends of the said with eyes at its ends to receive the standlevers, substantially as herein shown anddeards F, substantially as herein shown and de- IO scribed; scribed.

3. The combination with the pivoted brake- 4 5 levers E, provided with the standards F, of RICHARD PAGE the brake-shoes I, provided with the aper- Witnesses: tured lugs G, and the bolt H, passing through GEO. W. BARTLETT,

1 the lugs of the brake-shoes and provided D. H. BURROUGHS.
