IMPROVEMENT IN. SLED-BRAKES.

Specification forming part of Letters Patent No. 197,676, dated November 27, 1877; application filed October 11, 1877.

To all whom it may concern:

Be it known that I, HENRY W. SMITH, of Rainsburg, in the county of Bedford and in the State of Pennsylvania, have invented certain new and useful Improvements-in Sled- Brakes; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making -a part of this specification.

The nature of my invention consists in the construction and arrangement of a sleighbrake, as will be hereinafter more fully set forth. v

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, refer. ring to the annexed drawings, in which Figure 1 is a side elevation of a sleigh embodying my invention, showing the brakes released. Fig. 2 is a longitudinal section of thesame, showing the brakes applied. A represents the top, B the knees, and O the runners, of an ordinary sled or sleigh, to whichmy brake is attached. In suitable boxes in or under the top frame A is placed a rockshaft, a, provided on one end with a lever, E, for turning the same. On this shaft, near each side, is secured a solid block, D, of malleable cast-iron provided with a projecting arm, D, in which is a slot, b. Upon a pin, d, in the corner of the block D, diagonally opposite the arm D, is hinged a-lever or pressplate, G, also of malleable iron. This lever is made in the angular form shown, and a rubber spring, h, is interposed between said lever and the arm D. Irepresents the brake-tooth,

pivoted to the runner O, and having a rod, 112, connected to its upper end. This rod passes rearward or upward through the slot b in thearm D, and connects with an eyebolt, i, which goes through the end of the lever G and through a rubber spring, h, placed on the outer side thereof, and a washer and nut placed on the end of said bolt.

' It will readily be seen that by turning the lever E forward the arms D and levers G are thrown into the position shown in Fig. 2, and

the brake-teeth I turned into the ground, or rather into the snow and ice.

It will also be seen that by means of the upon the rock-shaft a, and provided with the slotted arm D, the spring h, and the hinged lever G, connected to the brake-tooth, substantially as herein set forth.

2. The combination of the tooth I, rod m, eyebolt i, lever G, springs h h, and block D, with slotted arm D, all constructed substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 28th day of September, 1877.

H. W. SMITH.
