Abstract
A rotary cutter comprises a generally elongated plate-like handle having a bearing aperture defined at one end thereof, a shaft member supported by the handle and extending through the bearing aperture, a disc blade rotatably mounted on the shaft and lying in a plane perpendicular to the longitudinal axis of the shaft member and in parallel to any one of the opposed surfaces of the handle, and a device for adjustably applying a frictional force to the disc blade in a direction generally perpendicular to the disc blade. The disc blade is, when the rotary cutter is in use, rotated in contact with the material to be cut in a controlled manner.
Claims7
A rotary cutter comprising:
- an elongated handle having extending through one end thereof a bearing aperture;
- a shaft extending through said aperture and supported by said handle;
- a disc blade rotatably mounted on said shaft and lying in a plane extending perpendicular to the longitudinal axis of said shaft;
- a guard disc having a diameter greater than the diameter of said disc blade, said guard disc having therein a guide slot, said guard disc being mounted at said one end of said handle, with said shaft extending through said guide slot, for sliding movement in opposite directions longitudinally of said handle between an exposing position, whereat a portion of the periphery of said disc blade is exposed for cutting, and a concealing position, whereat said portion of said periphery is concealed by said guard disc;
- and
- means for adjustably applying a friction force to said disc blade in a direction substantially perpendicular thereto, and for thereby enabling said disc blade to be rotated in a controlled manner in contact with material to be cut.
