THOMAS HALVORSEN, or new YORK, N. Y.
IMPROVEMENT IN DEVICES FOR SHARPENING SCISSORS.
Specification forming part of Letters Patent No. 1 37,135, dated March 25, 1873.
To all whom it may concern:
Be it known that I, THOMAS HALVORSEN, of the city, county, and State of New York, have invented a new and Improved Scissors- Sharpener, of which the following is a specification:
Figure 1 is a perspectiveview of my invention Fig. 2, a vertical section of the same on the line 0 c, Fig. 3; and Fig. 3 a top View, with a part open to show arrangement of files.
Similar letters of reference indicate correspondin g parts.
The object of my invention is to furnish to tailors, seamstresses, and the public in general, a small and convenient instrument which can be applied to a table or other convenient place for sharpening of scissors and shears. It consists of the arrangement of two files under a certain angle, so that by introducing one blade of a pair of scissors held in position by a strong spring, and sliding the same back and forth, the edge is sharpened rapidly and evenly by the files.
In the drawing, A represents the metal frame by which the scissorssharpener is connected with any fixed body or piece of furniture, held in position by set-screw B. To the upper horizontal plate a is screwed, cast, or otherwise connected, the rectangular frame 0, of brass, bronze, or othersuitable metal. One
side, 9, thereof is vertically extended and provided at its inner side with a file, b. A horizontal slot, 61, allows the filings to drop out. A strong band-spring, D, is firmly screwed to the outside of frame 0, parallel to side a, and presses, with its bend 0, toward the same, so that when the scissors-blade f (Fig. 2) isintroduced it is strongly pressed on file 1). Below spring D the upper side 9 of frame 0 is inclined under an acute angle toward side a, and another file,'h, placed on it at a short interval from file b in such a manner as to act uniformly on the edge of blade f and connect with slot (1. Several strokes of the blade f over the files b and h will suffice to sharpen the blades of the scissors, providing thereby an easy, quick, and convenient method of sharpening the scissors, thereby expediting the work of the same. The slot dadmits also the replacing of files h when the same are dull in consequence of long use.
Having thus described my invention, I claim as new and desire to secure by Letters Patcut- The scissors-sharpener composed of frame (3, spring D, files b and h, slot d, substantially as and for the purpose described.
THOMAS HALVORSEN.
