Description

Appellant (hereinafter Whiteman) is the owner of United States Letters Pattent No. 2,198,929, issued April 30, 1940, on application filed May 3, 1939, for a Cement Floor Finisher. The machine of the patent is described briefly as follows: Trowels or blades extending substantially radially to a vertical shaft are rotated by means of a motor geared to the upper end of the shaft. At the lower end of the shaft is attached a plate to which the blades or trowels are connected by means of pins.The plate and the trowels are rotated by the action of the motor on the shaft through reduction gears, and the contact of the rotating trowels on the cement surface accomplishes the finishing process. While in operation the weight of the machine is entirely supported by the trowels.
