UNITED' STATES PATENT OFFICE.
BLOOMFIELD BBOWER, OF NEW YORK, N. Y.
IMPROVEMENT IN RULERS.
Specification forming part of Letters Patent No. 126,260, dated April 30, 1872.
York, have inventcda new and useful Improvement in Paper-Cutters, of which the following is a specilication:
Figure I represents a top view of my irnproved paper-cutter embodying my invention. Fig. II is a front View, and Fig. Ill is a crosssection of the same.
A is a strip of metal, made of any desired length and width. This plate should be made concave at its cross-section, (see Fig. IIL) for the purpose of stiliening the same, so as to allow it to be made of light material. It is made wider than the remaining part of the plate A,
and at each side of this central part B the plate is cut through for about one half of its width, as shown at o o, Fig. I. This strip B is then bent upward and curved to form a handle for the plate, as shown in Fig. III.
Instead of making this handle B in one piece -with the plate A, as here shown, the same may be made of a separate piece, bent in the shape as represented at Fig. Ill, and then riveted or otherwise fastened on the top of the plate A; but I prefer to make the same in one piece with the cutter-plate as above specified on account of its great simplicity and cheapness.
When the paper-cutter is used the same is placed upon the sheet of paper to be cut or 'torn off, touching at lirst only in two parts on account of its curved shape, as before described, to allow the same to be easily moved until in its proper place, when, by a slight pressure, the whole surface or edge will he brought to bear upon the paper when the pa per may be easily cut or torn o in a line with the front edge.
What I claim as my invention, and desire to secure by Letters Patent, is
The paper-cutter composed of the blade A, curved as shown in Fig. II, and the bent handle B, substantially as herein specified.
