GEORGE HENRY CHAPMAN, OF ROCHESTER, MINNESOTA.
SLED-BRAKE.
SFECIEICATION forming part of Letters Patent No. 309,76L, dated December 2.3, 1884.
Application tiled April l0, 1884.
To @ZZ whom it may concern:
Be it known that I, GEORGE HENRY CHAP- MAN, a citizen of the United States, residing at Rochester, in the county of Olmsted and State of Minnesota, have invented certain new and useful Improvements in a Combined Sled Brake and Dog, and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertaius to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
Figure l of the drawings is a side view of my sled, and Eig. 2 is a similar view showing an operating rod and lever attached tothe body of the sled.
This invention has relation to improvements in sled-brakes; and it consists in the construction and novel arrangement of devices, as will be hereinafter more fully set forth, and particularly pointed out in the claim appended.
In the accompanying drawings, the letter A designates a sled, and B a runner thereof, having slide-bearings G, in which the brake-prong D has vertical reciprocating motion.
Erepresents a strong fulcrum-bearing, which is secured to the runner-frame in front, or in rear of the brake D, and to the upper end of this bearing is pivoted the lever F, to the short arm G of which the upper end of the brakebar D is connected. The long or heavy arm H of the lever extends in the opposite direction, and to it is pivoted a vertically-extending operating-rod, K, moving in bearings, and hav- (No model.)
ing a loop-handle at its upper end. The proportion of parts is such that when the operating-rod is untouched the long arm of the lever will fall, raising the brake clear of the runner. \Vhen, however, the operating-rod is pulled upward, the brake will be caused to descend below the runner-shoe and enter the ice or snow in such a manner as to do effective work. It can be operated as a brake in going down a hill, or as a dog in ascending agrade. When the operating-rod is not held, the brake will automatically release itself; hence it is never liable to be casually thrown into action when not required.
On a box-sled it is preferred to arrange the operating-rod in advance of the brake-bar; butin a lumber-sled or frame-sled the operating-rod will be in a more convenient position in rear of the brake.
y Having described this invention, what I claim, and desire to secure by Letters Patent, 1s-
In a sled, the combination, with the brakebar reciprocating vertically in slide-bearings, and the vertically-sliding operating-rod, of the lever having its fulcrum on the frame, its short arm pivoted to theupper end of the brakebar, and its long or weighted end connected to the operating-rod, the bell-crank, connecting-rod, and hand-lever, substantially as specified.
In testimony whereof I affix my signature in presence of two witnesses.
GEORGE HENRY CHAPMAN.
