HARRISON A. DENNEY, OF REARDAN, WASHINGTON.

BRAKE.

SPECIFICATION forming part of Letters Patent No. 664,213, dated December 18, 1900.

Application fled April 13, 1900. Serial No. 12,770. (No model.)

To all whom t may concern:

Beit known that I, HARRISON A. DENNEY, a

citizen of the United States, residing at Reardan, in the county of Lincoln and State of Washington, have invented new and useful Improvements in Brakes, of which the following is a specification.

This invention relates to new and useful improvements in brakes, and is especially adapted for use upon sleds and similar devices. Its primary object is to provide a device of simple and durable construction which maybe readily applied to a sled of ordinary construction and which is easily operated and effective in use.

To these ends the invention consists in the novel construction and combination of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings, showing the preferred form of my invention, and in which- Figure l is a side elevation of the device applied to a sled. Fig. 2 is a perspective view of the brake beam and shoe, and Fig. 3 is a bottom plan view of said beam and shoe.

Referring to said flguresby numerals of reference, lis a sled, to one side of which near the base of the runner is pivoted a brakebeam 2, having a downwardly-inclined and sharpened lower edge 3, said beam reduced in size at its free end 4., which end projects through a shoe 5, preferably rectangular in form and arranged in a plane at right angles to the vertical plane of the brake-beam. This s hoe is sharpened at its lower edge, said edge being flush with the sharpened edge of the brake beam. The shoe is secured to the beam preferably by means of a pin 6, as shown. Pivoted to the side of the sled is a bell-crank lever 7, which is connected with the beam 2 by means of a link 8, as shown. A rod 9 connects the opposite end of the bellcrank lever with a lever 10, pivoted to the sled at any suitable point, and having a dog 1l, adapted to engage with a toothed segment l2, whereby the lever l0 may be locked at any desired inclination. It will be understood that when said lever lO is thrown forward upon its pivot the beam 2 will be thrown downward, bringing the cutting edge 3 thereof and the edge of the shoe 5 into engagement with the snow or ice, thus serving to retard the progress of the sled. When themotion of the lever l0 is reversed, it is obvious that the Ybeam 2 will be drawn upward.

It will be seen that the shoe 5 may be readily detached for sharpening, dac.

In the foregoing description I-have shown the preferred form of my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is- A brake for sleds comprising a pivoted beam having a lower cutting edge, a shoe detachably secured to the free end thereof, a sharpened lower edge to the shoe, a bellcrank lever, a link connection between said lever and beam, an operating-lever, a rod connecting said lever and the bell-crank lever, and means for locking the operating-lever at a desired inclination.

In testimony whereof I affix my signature in presence of two witnesses.

HARRISON A. DENNEY.
