:
A ROTARY SKATE TRACTOR
The latest and most unusual construction in tractors is being operated at Grand Rapids, Michigan,
by the inventors, Frederick K. Burch and Joseph West. It is designed for use over snow and ice and,
in substance, is a rotary skate with powerful propulsion. The frame of the tractor is mounted on two
drums, right and left, bisected transversely, and set on a heavy shafting. The drums are made of
sheet iron, over a basswood frame, on which are set numerous pieces of channel iron. The left-hand
drum rotates clockwise and the right hand drum, counter-clockwise, thus neutralizing the power
along the line of progression. One single runner in front, connected by steel cable through pulleys
to the wheel, makes accurate steering possible.
FLUSHING WITH A TRAIN OF CARS
A train of cars, or carriages, flushes the streets of Buffalo and keeps the asphalt spotlessly clean.
When the new device is being hauled up the street to a new location it looks the part of the
fabled sea serpent, but it is in reality the most efficient means yet invented for scrubbing on a large
scale. It is a means for moving the curb hydrants into almost any desired position, by means of an
attachable steel pipe line with many nozzles.
