IMPROVEMENT IN CAN-OPENERS.
Specification forming part of Letters Patent No. 190,560, dated May 8, 1877 application filed June 25, 1875.
To all whom tt may concern:
Be it known that I, Lnwis CUTTING, of San Francisco, in the county of San Francisco and State of California, have in vented an Improved Gan-Opener; and I do hereby declare that thefollowing description and accompanying drawing are sufficient to enable any person skilled in the art or science to which it most nearly appertains to make and use my invention without further invention or experiment.
The object of my invention is a can-opener which shall be an effective opener, and can be manufactured so cheaply as to become a household implement; and the invention consists of a can-opener composed of a cast-iron handle with bolsters and a steel sickle-shaped blade, all cast togethen the sickle-shaped blade being beveled wholly on the right-hand side of its convex edge, as a new article of manufacture, all as more fully hereinafter explained.
In the drawings, the figure represents a side view of my can-opener as cutting a circle in the top of a can.
0 represents the handle of the device, c0mposed 'of cast-iron, and having bolsters 0 cast therewith,and projecting from the sides of the lower end of the handle. This handle is short, and is formed to fit the hand. A is the blade, constructed of steel, and made in the form of a sickle-blade. This blade is beveled wholly on its right-hand side, leaving the cuttingedge B on the left-hand side of the blade, thereby enabling it to out a smooth circle around the top of the can. The steel blade is cast in the handle, being put in the mold for that purpose.
In operating my can-opener, the point of the blade is thrust through the top of the can, and brought down so that the bolsters will rest on the can and act as a fulcrum, when the implement is worked with an oscillating movement and a smooth circle cut around the head of the can.
This article can be manufactured so cheaply as to bring it into general use, and make it a necessary accompaniment with the culinary department of every household.
Having thus fully described my invention,
LEWIS CUTTING. Witnesses:
