snaren BRAKE.

Application filed OctoberSO, 1920. Serial No. 420,764.

T 0 all u* 710m it/may concern Be it known that l, Josnrir A. Annari- CHUK, a citizen of the Dominion of Canada, residing at Rossburn, in the Province of Manitoba and Dominion of Canada, have invented certain new and useful Improve-j ments in Sleigh Brakes, of which the following is a specication.

rlhis invention relating to sleigh brakes, has for one of its objects to provide a manually operable brake shoe adapted to be projected downwardly to a' point beneath the lower side of the runner for engagement with a snow or ice-bed to retard the forward travel of the sleigh.

A further object lof the invention is to provide a brake device for sleighs wherein a pair of tensioned' brake shoes are maintained normally elevated above the lower sides of the runners and are operated by a cross arm and foot lever connected thereto for moving the same into engagement with the ground surface beneath the runners.

Vith the above and other objects in view, the present invention consists in the novel form, combination and arrangement of parts hereinafter more fully described in connection with the accompanying drawings wherein like reference characters indicate similar parts throughout the several views.

ln the drawings,

Figure 1 is a detail sectional view partly in elevation of a sleigh and brake therefor constructed in accordance with the present invention,

IFigure 2 is a rear elevational view, partly in section of the sleigh, and

Figure 3 is u. detail sectional view taken on line lll-lll of Figure 1 showing the resiliently mounted brake shoe.

ln the accompanying drawing which shows a preferred embodiment of the invention, there is illustrated a sleigh including side runners d provided with the usual runner plates 5, the curvature of the runners being shown in side elevation in Figure 1, the forward ends thereof curved upwardly in the usual manner. A body carriage or platform 6 is suitably supported in an elevated position with. respect to the runners` Brake devices are associated with the runners 4f and include guide frames of the type shown in detail in Figures 1 and 3, there being illustrated a cylinder 'Z supported on brackets 8 and secured as at 9 to the runners ei, the bottom wall 1() of the cylinder i having a centralr op'eningll for the passage of the rod 12 that carries a'brake shoe 13 upon the lower end thereof outwardly ofthe cylinder 7. Each runnert and ruimer plate 5 is provided with an opening 111 into which the lower end of the shoe 13 projects at all times, the shoe being adapted for downward projection beneath the lower plane of the sled runner for engagement with the road.- bed. To hold the shoes elevated, as shown 'in Figure 3, a coil spring 15 is arranged in each cylinder 7 surrounding the rod 12, the spring engaging at its lower end the bottoni wall 10 ofthe cylinder while the disk 16 secured 'upon the rod 12 is engaged by the upper end 'of the spring, said springs'norinally holding the shoes 13 elevated at thek upper ends of the runner openings 14. As shown in Figure 2, the upper ends of the rods 12 are connected by the cross bar 17 arranged intermediate the platform 6 and the runners 1.

To provide for the depression of the shoes, a bracket 18 is centrally secured to the underside of the platform 6 adjacent the forward end thereof and has journaled therein arod 19 supported at its ends in the brackets 20, curved links 21 being connected to the ends of the rod 19 and having the lower ends thereof slotted as at 22 through which the connecting rod 17 for the shoe rods 12 eX- tends. A curved pedal arm 23 is connectedl at its lower end to the rod 19 and projects outwardly through. an opening 24@ in the platform 6 with a foot engaging portion formed at the upper end thereof. In the normal position of the shoes, the

saine are retained elevated by the springs engaging the rod disks 16 and to lower thc shoes through the runner openings 1d for engagement with the roadbed, the pedal arm is pressed. downwardlyto move the rod 1.9 in itsjournal bearingsy thereby shifting the `links 21 connecting the rod 19 with the rod 17 with a subsequent lowering of the shoes through the runner openings 14- and against the tension of the springs 15. During the lowering movement of the shoes, the connecting rod 17 moves through the slots 22 in the ends of the links 21 to compensate for the shifting movement of the links. Then pressure relieved upon the 'pedal arm the springs 15 will restore the shoes 18 to their normal elevated positions.

lVhile there is herein shown and described the preferred embodiment of the invention,

it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as hereinafter claimed.

That is claimed as new is:

l. A sleigh brake comprising in combination with a sleigh having runners and a platform section, cylinders supported upon the runners, a rod in each cylinder, a brake shoe carried by the rods and externally of the cylinders, coil springs surrounding the rods Within said cylinders to hold the shoes normally elevated, a connecting bar between the rods and carried thereby and foot operating means for depressi ng the shoes against the tension of the springs.

2. A sleigh brake comprising in combination witha sleigh having runners and a platform section, upstanding brackets upon the runners, cylinders integrally carried by the brackets and spaced above the runners, brake shoes having rods projecting through said cylinders with the shoes projectingI eX- ternally of said cylinders and engaging within openings formed in the runners,

springs carried by the rods to hold the same normally elevated and foot operated means for depressing said shoes.

A sleigh brake comprising in combination with a sleigh having runners and a platform section, a shaft ournaled beneath said platform section, curved links carried by the opposite ends of said shaft and being slotted at their lower ends, cylinders supported upon the upper surface of the runners, a rod in each cylinder, a brake shoe carried by the lower end of each rod,sai:l. shoes being externally of the cylinders and received Within an opening formed in each runner, coil springs Within the cylinders and surrounding the rods to hold the shoes normally elevated, a connecting roll beneath said platform rigidly carried by the upper ends of said brake shoe rods and received Within the slots of the said curved links and means for rotating said shaft for depressing` the shoes against the tension of the springs.v

ln testimony whereof l affix my signature.
