UNITED STATES PATENT OFFICE.
WM. E. ROBERTS, OF ORANGE, CONNECTICUT.
SCISSORS-SHARPENER.
Specification of Letters Patent No. 18,709-, dated November 24', 1857.
T o all whom 'Lt 'may concern:
Be it known that I, VVILLLAM E. ROBERTS, of the town of Orange, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Scissors-Sharpeners; and I do hereby declare that the following is a full, clealr, and eXact description of the construction, character, and operation of the Same, reference being had to the accompanying drawings, which make a part of this specification, in which Figure l is a perspective View of a double Sharpener. Fig. 2 is a perspective view of a single one. Fig. 3 is a section of a single Sharpener, cut through the center so as to Show the steel, and the bevel.
I make the block in a cubic, or any other convenient, form, for two Sharpeners as shown in Fig. l, or for one Sharpener, as shown in Fig. 2.
I cut the space, or spaces, b, in the block, to admit the blade of the scissors, of any convenient size; and with the proper bevel, (on one Side,) to the Steel to give the edge to the scissors blades, as seen in the drawings. I temper the steel in the usual way and insert it into the block in the position shown at a, in the drawings.
Having made the Sharpener, as before de- Scribed,-to sharpen the scissors, I pass one of the blades, (at a time) through the space, or opening, Z), holding the flat side of the blade firmly against the side, c, of the space, b, press its edge upon the steel, and work it through longitudinally till a perfect edge is formed, which will generally be effected by passing it through two or three times. Thus making a very convenient and ready Sharpener for Scissors, and other analogous articles, which may be used even by a child to do the work which has heretofore been considered diiiicult, and troublesome to persons of experience.
Vhat I claim as my invention, and desire to secure by Letters Patent, is-
The article of new manufacture, of seis sors Sharpener, when constructed, and fitted for use, substantially as herein described.
W. E. ROBERTS.
