lhvrrnn Srnrns MATTHEW T. PRESTON, OF CUTLER, ILLINOIS.

WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent No. 300,327, dated June 10, 188 1.

Application filed March 3, 1884.

To (ZZZ whom, it may concern:

Be it known that I, )[ATTHEXV T. Pnnsron, of Cutler, Ierry county, Illinois, have invented a certain new and useful Improvement in Wagon-Brakes, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings,

' the divided connecting-rod.

My invention relates to a brake which is not in any way connected to the body or bed of the wagon, so that the latter can be removed without having any effect upon the brake, or the brake being interfered with by its removal.

My invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Referring to the drawings, A represents the wheels, A the front axle, A the rear axle, A the hounds, and A the reach, of an ordinary wagon.

B represents the brake-beam, provided with shoes 13, and which is V-shaped, as shown in Fig. 2. It rests upon the bounds, and is strengthened by a. brace, 13*. It is held from vertical movement and from getting out of place by rods or bars B, with downturned ends secured to the hounds, and by means of loops or clevises B"-one at the apex of the beam and the other at the brace I3-bothembracing the reach, as shown in Figs. 3 and at. These loops may be secured to the beam and brace in any suitable. way. A block, 0, is secured to the reach, upon which the apex of the beam rests or bears. The beam is made in two parts connected at the apex by a metal bracket, 13, closed at top, bot-tom, and back, and into which the ends of the two parts of the beam lit and are held by bolts B.

D represents a rod connected to the brace R, which passes back through the beam and through the rear bolster, G, and connected to (No model.)

one end of a lever, H, fulcrumed at H to the bolster or axle.

D represents a spiral spring surrounding the rod D between the brakebeam and the bolster. The action of this spring is to force the 5 brake-shoes away from the wheels when the brake is not applied.

The outer end of the lever H is connected to a hand-lever, I, by means of a rod passing through the bolster G and over the brake- 6o beam. This rod is made in two parts, J J, the part J having it turned perforated end, J and holes or perforations J". The part J passes through the perforation in the end of the part J, and has a turned end, J, which enters any one or theholes J where it is held by a nut, J (See Figs. 5 and G.) The rod can thus be lengthened and shortened as the wagon is lengthened out and shortened up. The part J of the rod has a hook, J, on its outer end, to engage a loop or eye, I, 011 they hand-lever I. The rod can thus be llllllQOkGCl from the lever, so that the latter can be laid down into a horizontal position, to be out of the way in loading lumber, &C. 7

I.- represents a bracket consisting of a lower straight part, L", and an upper curved part, L", formed in one piece, and. secured to the front bolster, 1?, and one of its posts N. The curved partof the bracket has notches S0 or teeth L, which are engaged by a pawl, O, secured to the hand-lever I by pins 0', fitting in slots 0" in the pawl. The pawl slidesover the teeth of the bracket as the lever is pushed forward to apply the brake, and prevents the return of the lever until it is raised to disengage it from the bracket. It is held in contact with the bracket, except when pulled back, by a spiral. spring, P, in one of the slots 0"? The pawl can he raised by pins 9 or projections C3 Q, secured to the upper ends of the pawl andlevcr, and which can be grasped by the hand.

It will be seen that my brake is not connected in any way to the bed or body, and it is very simple in its construction and effective in its operation.

I claim as my invention-- 1. In a wagon-brake, the combination of the brakebeam provided with a bracerod beam 13, brace B bracket B l06ps B, rod 1), spring 1), levenH, rod J J, bracket L, hand- 1o lever I, with pins 0', spring P, and pawl 0,

connected to the brace and passing back through the beam and rear bolster of the Wagon, spiral spring surrounding the rod between the bolster and been], lever to which with slots 0 all substantially as set forth. the rod is connected, and a pull-rod connecting MATTHEW T. PRESTON. the said lever with a hand-lever at the front In presence ofend of the wagon, substantially as set forth. JAMES CAMPBELL,

2. In a Wagon-brake, the combination ofi CHARLES PRESTON.
