UNITED STATES OTTO SEVERIN R'U'UD, 0F RYIllliIOElbl', NEAR ROVER-U1) STATION, NOE'WAY.
DRIVING WHEEL.
Application filed October 3, 1922.
To all whom it may concern:
Be it known that I, O'r'ro SEVERIN 'RUUD, citizen of Norway, residing at Rymoen, near Roverud Station, Norway, have invented certain new and useful Improvements in Driving Wheels, of which the following is a speci cation.
The present invention relates to a driving wheel for motor sledges and the like,
1 and is particularly characterized by the fact,
that the catching devices located at the periphery of the wheel are arranged in such a manner, that they will easily grip the road bed or surface and thereby secure a firm hold. Owing to their form, they ordinarily will not slip on the road whereby losses of energy are avoided. V
The invention is shown in the accompanying drawing. in which:
Figure 1 shows the wheel in side elevation.
Figure 2 is an elevation of a single lug attached to the wheel.
The wheel consists of a disc 1 of steel or the like. The disc is formed with a bore 2 for the shaft and with holes 3 for screws by means of which the disc is fixed to a suitable nave. At the periphery of the disc 1 a suitable number of traction increasing lugs 4 are arranged, which are fastened to the disc by means of screws or rivets 5. The lugs are suitably made from round-iron and are tapered or pointed towards their outer ends, in order to grip into the road bed. In order to facilitate the conducting ofthe lugs into and out of contact with the road and to prevent snow or the like from settling in the lugs, the same are fixed Serial no. 592,167.
to the disc 1 in such a manner, that each of the screws 5 holds a leg from each of two adjacent lugs.
Each lug therefore comprises two spirals integrally connected at their traction points and the respective ends extending in different directions.
It will be easily understood, that these lugs 4 will grip the road bed in a firm hold, and that the same will be easily brought into and out of engagement with the road, be cause no legs of the lugs are radially placed upon the disc but all are located at a certain angle to the periphery of the disc, so that one leg of the lugs will be carried at an oblique angle down into the road bed or surface, whereas the other leg of the same lug during the continued rotation of the wheel will be carried up from the road surface at an oblique angle to the same, whereby breaking strains or the like will be reduced.
I claim In a driving wheel, the combination of a disc; lugs of circular cross section tapered at their traction points, each comprising two spirals integrally connected at their traction points and their respective free ends extending in different directions and to op posite sides of said disc; and rivets for securing the respective ends of two adjacent lugs together and to said disc.
In testimony whereof I afiix my signature.
