To all 'whom z' may concern.'
Be it known that l, JOHN HANDELAND, a citizen of the United States, residing at rl`wo Harbors, in the county of Lake and State of Minnesota, have invented certain'` new and useful Improvements in Power-Propelled Sleds; and l do hereby 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 appertains to make and use the same.
My invention relates to improvements in power propelled sleds; and, to this end, it consists of the novel devices and combinations of devices hereinafter described and defined in the claim.
ln the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.
Referring tothe drawings: Figure 1 is a side elevation of a bob-'sled having the invention incorporated therein; Fig. 2 is a rear end elevation of the same; Fig. 3 is a plan View of one of the rear sled runners removed from the sled body., on an enlarged. scale; Fig, 4 is a longitudinal vertical section taken on the line Xt X* of Fig. 3; and Fig. 5 is a transverse vertical-section taken on the line X5 X5 of Fig. il.
The numeral V1 indicates the body ot a bob-sled, and the numerals 2 and indicate, respectively, the front and rear runners of said bob-sled. Secured to the front end of the body 1 is a depending castingi to which the front runners 2 are secured for common horizontal swinging movement and for inde- `pendent vertical oscillatory movements.
Any suitable steering device may be provided for steering the front runners 2 and for the purpose of this case is not thought necessary to illustrate the same. Depending from the under side of the rear portion of the body 1 is a pair of brackets 5 to which is secured a pair of axially alined` outwardly projecting stub axles 6.
As shown, each of the rear runners i' eamprises a' pair of laterally spaced duplicate members each having a pair of upwardly converging arms 7. To the upper ends of the four arms of each runner 3 is rigidly secured a hub 8. 'These hubs 8 are loosely journaled. one on each of the axles 6, permitting free, independent vertical oscillatory movements of the runners 3. The members of each rear runner 3 are rigidly connected and held laterally spaced by a multiplicity of horizontal rods 9 that are laterally spaced longitudinally on said runners. Journaled on the rods 9 of the respective runners 3 are rollers 10 over which runs a link belt 11 having road engaging teeth 12. As best shown in Fig. 5 the lower faces of the rollers 10 are set rigidly above the lower edges of the members of the runners 3 so that the belt 11 running thereover follows the outline of the road engaging surfaces of the runner members. rlhe depending edges of the members of the runners 3 also hold the link belts against edgewise movements and in position on the engaged rollers 10. At the front and rear ends of each runner 8 are journaled respectively sprocket wheels 13 and 14 over which runs the respective belt 11. An idle guide sprocket wheel 15 is journaied to the front arm 7 of each runner 3 and under which wheel the respective belt 11 runs.
To cause the bob-sled to move forward the belts 11 are driven, in the direction of the arrow marked thereon in l*1 ig. 4, by an explosive engine mounted on the body 1. This engine is indicated as an entirety by the numeral 16 and may be of any desired construction. The' belts 11 are independently driven from the engine 16 by the following connections, to-wit: Keyed to each end of the engine crank shaft is a sprocket wheel y17 and loosely journaled on each stub axle 6 is a relatively large sprocket wheel 18 and -a relatively small sprocket wheel 19, connected for common rotation. The sprocket wheels 17 and 18 are alined and a sprocket chain Q0 runs thereover. rThe Sprocket wheel 19 is alined with a sprocket wheel 21 on the shaft of the respective wheel 13 and over which sprocket wheels 19 and 21 runs a link chain 22. ln actual practice clutches,
not shown, will be provided for rendering either of the driving connections from the engine to the road engaging belts 11 operative and inoperative, at will.
From the ioregoinfr description, it is evident that during the forward movement of the bob-sled the weight of the load on the runners 3, together with the teeth 12, will securely hold the underlying sections of the link belts 11 on the road bed and against slippage. Under the roi-ward drawing action of the upper runs oi' the belts 11 over the sprockets 1l the runners 3 are caused to slide forward over the underlying portions of the belts 11.
What I claim is: tWo runner members, a link belt arranged A sled runner comprising a pair of laterto run over said sprocket Wheels and rollers ally spaced runner members rigidly conand having road engaging teeth, and means nected by a plurality of rods, a pair of vfor drivingone of said sprocket Wheels.
