BRAKING nnvion FOR sLEns.

Specification of Letters Patent.

Application filed February :13, 1915. Serial No. 8,093 l To all whom it may concern:

Be it'known that 1, JAMES P. SHARP, a citizen of the United States, and a resident of Salt Lake City, in the county of Salt Lake and the State-of Utah, have invented certain new and useful Improvements in Braking Devices for Sleds, of which the following, together with the accompanying drawings, constitutes a full, clear,.and exact specification, which will enable others skilled in the art to which my invention appertains to make and use the same.

My invention relates to braking devices for sleds and its object is to provide means for. easily dropping one or more suitable bands or bracelets under the sled runners after the manner of a so-called rough lock. l/Vhile my device is intended to be used primarily in connection with coasting sleds in cases of emergency, yet its use is not restricted thereto.

The features upon which I desire protection are summarized in the appended claims.

In the drawings, which illustrate merely one embodiment of my invention, Figure 1, is a perspective view of a common sled showing my improvement applied thereto, a portion of the steering bar being broken away to show a is a partial, enlarged side elevation of the same, and Fig. 3-is a fragmentary perspeotive view of a modified detail.

Referring to the drawings (3) represents an ordinary coasting sled, and (4c) the runners thereof, on which are strung the encircling bands or bracelets (5), these being preferably made of metal and having any suitable form, though if made of one piece of metal it may be desirable to have what is commonly known as an open link for the sake of easy application to the runners.

Normally the bracelets (5) hang high up on the front of the runners, in order not to interfere with the operation of the sled, and they are held in this position by the bent fingers (6) which project from the rod (7), the latter being pivoted at (8) in the framework of the sled.

Instead of pivoting the rod (7 directly in the framework as shown in Figs. 1 and 2 it may be hung in removable clips or stirrups (8) as shown in Fig. 3, these stirrups being clamped to the framework by a bolt (8). The form of the stirrups (8 and the method of attaching them may be varied to suit any special requirements.

detail more clearly. Fig. 2

the said runners,

Patented May 30, 1916.

The fingers (6) are adapted to allow their lower extremities to bear-against the inner surfaces of the runners (4) and are'held in yielding contact thereon, preferably by the springs (9), as shown. The pivoted rod (7) carries the rigidly attached operating lever (10) which latter may terminate in the ball (11) for the purpose of being con.-

.veniently grasped by the hand, or touched by the foot, of the operator.

In usmg, my device, the lever (10) is pushed over sufficiently far, as indicated by dotted lines, so, as to allow the bracelets (5) to slide down along the runners by gravity. The bracelets (5) on touching the surface (as shown by the dotted lines at (5 in Fig.

2) on which the sled is sliding, are soon worked back along the runners until they catch on the forward standards of the sled and finally lodge in the positions shown approximately by the dotted lines' (5 in Fig. 1, thereby retarding the motion of the sled and quickly bringing the same to a stop.

Having fully described my invention, what I claim is 1. The combination, with the framework and the runners of a sled, of arms pivoted in the said framework and adapted to have their free ends touch the said runners; means for normally holding the arms in yielding contact with the runners; and bracelets, independent of the said arms, loosely encircling the said runners, the said arms being adapted to normally support the said bracelets in predetermined positions on the said runners.

2. In a sled, the combination with the framework and therunners thereof, of pivoted arms adapted to have their free ends bear against the said runners, means for normally holding the free ends of the said arms against the runners, and bracelets, independent of the said arms, movably strung on the said arms being adapted to support the bracelets on the said runners at certain predetermined points, and 7 ter' being adapted to thereupon gravitate downwardly along the said curved portions of the runners for the purpose specified.

4. In a braking device for sleds having runners the combination With the sl'edframe Work, of removable clips suitably fastened thereto, a rod pivoted in the said clips, fingers projecting from the said rod, the said purpose specified.

5. The combination With the framework and the runners of a sled, of stirrups removably attached to the said framework, arms pivoted in the said stirrups and adapted to have their free ends touch the said runners, means for normally holding the arms in yielding contact With the runners; and bracelets, independent of the said arms, loosely encircling the said runners, the said arms being adapted to releasably support the said bracelets in vpredetermined positions on the said runners for the purpose specified.

In; testimony that I elaiim this invention as my own, I have signed this specification in the presence of two: subscribing Witnesses.
