Description: |
| Abstract:
The primary object of this invention is to secure an even application of power to the rear roll of a tandem road-roller so as to avoid all twist and strain upon the spokes thereof, and to prolong the life of the gearing and avoid unequal strain upon the frame of the machine.
Claim:
In a road roller, in combination, a main frame, a roll mounted on said frame, continuous racks within the roll at the opposite ends thereof, two sets of gearing at opposite sides of the frame extending into the roll and in mesh with said racks, fixedly mounted shields fitted within the ends of said roll adjacent to said racks, said gearing comprising short shafts, brackets forming bearings for said short shafts mounted on said frame and extending into the roll, beyond the planes of said racks, pinions on said shafts in mesh with said racks, said brackets supporting said shafts on opposite sides of said pinions, and gear wheels on the outer ends of said short shafts, said shields having openings to accommodate said brackets, anal an engine driven shaft mounted on said main frame adjacent to said roll and having pinions in mesh with the gear wheels of said short shafts. |
