IMPROVED SLED-BRAKE.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern.-

Be it known that we, S. A. Columns and A. J. OUMMINS, of Vienna, in the county of Warren, and State of New Jersey, have invented certain new and useful Improvements in Sled-Brakes; and we do hereby declare that the following is a full, clear, and exact description thereof, sufficient to enable others skilled in the art to which our invention appertains, to make and use the same, reference being had to the accompanying drawings, forming part of this specification, and in which Y Figures 1 and 2 are side elevations, showing our sled-brake, and a modification of the same, applied to sleds.

Figure 3 is a partial top view of a sled, having our brake, and the modification thereof, applied to opposite sides. I I

Our invention consists in the employment of an angular lever, pivoted to the runner,- and having pivoted to it spurs or dogs, which, as the slotted tongue, connected with the angular lever, is moved back, are caused to penetrate the surface over which the sled is passing, and thus arrest the progress of the vehicle.

In the modification of our invention, instead of the angular lever we employ a flat plate of metal, pivoted to the runner, and also to a cross-bar, connected with the sliding tongue, dogs being also hung to this crossbar, and confined within a clevis or link, pivoted to the runner, as hereinafter fully described.

The nature of our invention will be better understood by reference to the following description, in'com nection with 'theaccompanying drawings, wherein similar letters of reference indicate corresponding parts in the several figures.

In the drawings A A represent the runners of a sled, between which,

at the front, a transverse rock-bar is mounted;

This latter is provided with hounds a a, between which the tongue B is fitted to slide, being formed with a slot, I), through which pass pins or frictionrollers e c, fixed in the bounds.

d is an arm, secured on top the tongue, near its rear end, and projecting backward.

To this extension d is jointed a bar, 0, rigidly secured to the centre of a transverse movable bar, 0.

f is a fiat piece of metal, secured on top the bar a, and serving to limit the vertical movement of the tongue.

To each end of the bar 0 is hung an angular lever, D, which, at its lower front end, is pivoted between plates 9 g, aflixed to the sides of therunners.

h h are p'rojeotions, extending downward, from each side of the lever D, at its angle. These extensions enclose therunners.

In front of each projection h is hung a dog, 1', which,

by'penetrating the surface, serves to retard the motion of the sled.

When the horses are proceeding as usual, the tongue is kept forward to the full extent of its movement.

This causes the lever D to be held up, and the dogs are not. in contact with the surface over which the sled is passing.' But when the horses are held in, as during the descent of a hill, the lever D is depressed,

and the dogs forced into the snow or ice, thus arresting the progress of the sled.

Vertical grooves (not shown) are provided in the front edge of each projection h, to receive the dogs, and prevent any lateral twisting or undue strain of the same. i

When backing the team, the lever D is, of course, depressed, but the dogs, by contact with the surface, are turned out of the way, so as to be inoperative.

The modification of our sled-brake is made as follows: 4

E E are flat plates of metal, hinged between the plates g, aifixed to the runner, and also loosely connected with the cross-bar O.

'It will be understood that there is one of these plates at each end of bar 0.

Near each end of the bar 0, and fitted to turn thereon, are dogs F 11, one on the outside, and one on the inside of each runner.

These dogs are enclosed within a clevis or link, G, pivoted to the plates 9.

The operation of the brake just described is the same, essentially, as that before specified, as will be obvious.

The bar 0 may be dispensed with, and the crossbar O placed over the extension (I of the tongue, and secured thereto, so as to move with it. In this case,

rods connect the extremities of bar 0 with the upper ends' of the levers D or plates E.

Our brake is simple and durable in construction, and'elfective in operation, and is applicable to sleds of various styles, whether light or heavy.

Having thus described our invention,

What we claim as new, and desire to secure by Letters Patent, is-

1. The combination of the angular levers D, pivoted to the runners, and provided with dogs 1' and proje'ctions h, the cross-bar O, the slotted tongue B, and the rock-bar, with hounds a, all constructed, arranged, and operating substantially as herein described.

2. The combination of the swinging dogs F, clevis G, pivoted plates E, cross-bar O, the slotted tongue.

B, and the rock-bar, with hounds a, all constructed, arranged, and operating substantially as herein described.

To the above specification of our improvements-in witnesses.
