"Vintage Machinery" entry for Joseph W. Fawkes
Description:
This patent was for one of the first steam plows built in the U. S.

Description:

By my improvements in locomotive-plows, wherein I employ a large barrel-shaped or bulged driving-wheel for the propulsion of the machine, I avoid the sinking in the earth ofthe wheels hitherto employed, and thus enable me to employ the locomotive in the culture of soft land, or where it is desirable to pass the locomotive over plowed land in harrowing or seeding, &c. This driving-wheel is furnished with spuds or spears, admitting of being projected or withdrawnand retracted. By this means a greater hold to the wheel on the earth can be given when the land is hard, thus securing the full traction of the machine. The plows are secured in an adjustable frame, (attached to the rear of the locomotive,) so as to admit of plowing and of being readily raised when requisite. In the guidance of the front wheels I employ a Windlass and band, operating a screw, which meshes into cogs of a segmental rack projecting from the rear of the axle of said front wheels.

Claims:

The employment of the barrel-shaped wheel or driver E, constructed with spurs k k in the manner described, in combination with guiding-wheels c c and screw D and segmental rack b, for the purpose of drawing the plow-frame and plows described in the manner set forth in the foregoing specification.
