SLED.

Application filed J'u1y20, 1921, Serial No. 486,221. Renewed August 1, 1923.

1 0 all whom it may concern Be it knownthat I, LEON Arrowroz, a citizen of the United States, residing at Yonkers, in the county of VVestchester and State of New York, have invented certain new and useful Improvements in Sleds, of which the following is a specification.

This invention relates to improvements in sleds and has for its principal object to provide a braking means for controlling the speed of travel of the sled, so that the same will remain under the control of the user at all times.

Another object of the invention is to provide a device which may be easily and cheap- 1y constructed and readily attached to sleds of the ordinary type without materially changing the construction thereof.

\Vith the above and other objects in view the invention consists in the novel construction, combination and arrangement of parts which will be fully set forth in the folloW-' ing specification, and illustrated in the accompanying drawings, in which,

Figure 1, is a top plan view of a sled equipped with this improved braking attachment,

Figure 2, is a side view of-Figure 1, showing the brake in elevated position,

Figure 3, is a front view in elevation of Figure 2,

Figure 4, is a side view of the device, showing the brake lowered into operative position.

Referring to the drawings by characters of reference, the numeral 10, designates in its entirety a sled, which comprises a pair of parallel runners l1 and 12 held in spaced parallel relation by means of the cross bars 13. Secured in spaced relation between the upper and lower horizontal bars of the runners are vertically extending brace rods 14.

Secured to and extending inwardly from the brace rods 14, are guide pins 15 adapted to be received in the guide slots 16 formed in the brake members 17, the rear ends of which are formed with downturned. contact members 18 for engagement with the surface traversed. Pivotally connected at the forward ends of the brake members 17 are links 19, the forward ends of which are in turn pivotally connected to the actuating levers 20. These levers 20 are pivoted as at 21 to the upper horizontal bars of the runners near their forward ends and are providedwith grips 22, by means of which the same are manipulated. Retractile coil springs 23 are connected to the lower ends of the levers and t0 the runners in such a manner as to exert pull upon the links to normally hold the brake members in elevated position.

In use it will be seen that when the sled 'is traveling rapidly down an incline and is operated to drag, causing-the direction of travel to change.

While in the foregoing there has been shown and described the preferred embodiment of the invention it is to be understood that certain minor changes in the cons-truction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

lVhat is claimed is z- A sled comprising a pair of runners, cross members holding the runners in spaced par allel relation, pairs of upright posts between the upper and lower elements of said runners, parallel brake members adjacent the runners, pins in said posts slidably supporting the brake members, contact members at the lower ends of the brake members adapted to be moved into contact with the surface traversed, links extending from said members to the front of said sled; spring means for holding thecontact members nor-' mally out of contact with the surface traversed, and vertical levers engaging said links, for each brake member whereby said brake members may be selectively operated and the direction of travel of the sled controlled.

In Witness whereof I affix my signature.

LEON Arrowroz.
