UNITED STATES WILLIAM A. JOHNSON, 0F YONKERS, NEW YORK.

PAPER-CUTTER.

Specification of Letters Patent.

Patented Dec. 14, 1920.

Application filed January 29, 1920. Serial. No. 354,77&-

1 '0 all-w ham/it may concern Be it known that 1, WILLIAM A. JOHNSON, a citizen of the United States. of America, and a resident of Yonkers, Westchester county, and State of New York, have, invented certain new and useful Improvements in PaPenCutterS, of which the followingis a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention: relates. to new-and useful improvements in paper cutters and it is especially designed for opening en velops or cutting the pages of books; Its object is to provide a simple device, which is neat and. attractive in appearance and efiicient in. op eration. Another object is to so construct the device as toprotect its cutting part. A still further object is to provide means for guiding the cutting, part not only for the purpose of facilitating-the operationand use, but to effectively protect the contents of an envelop to prevent, the latter] from being mutilated when. the envelop is opened.

These and other objects of the invention will. appear in the following specification in which I will describe the invention, the novel features of which will be set forth in the appended claims;

Referring to the drawings:

Figure 1 is a front elevation of a paper cutter which is made according to one embodiment of this invention, together with a portion of an envelop shown for the purpose of illustrating one of the uses of this device.

Fig. 2 is a. rear elevation of the device shown in F ig. 1.

Fig. 3 is a front end view, and

Fig. 4 is a bottom planview of the same structure.

Like characters of reference designate corresponding parts in all the figures of the drawings.

This paper cutter is stamped out of a single piece of sheet metal and bent into the form shown, so that it comprises two par allel portions which I shall call a frontrlO and a back 11, joined together by a part 12 which forms a partly cylindrical back. This may be knurled or roughened as shown in order to make it more easy to grip.

The back 11 is extended to form a forwardly projecting plow or inner guide 13 which is comparatively narrow so that it may be inserted readily between the ungummed corner of the flap 20 of an envelop parallel with theiedges of the back 11 except atthe: forward part of. the plow portion 13. The front, however, issomewhat wider than the back so that i-s. edges project beyond those of the back. and serve to protect the latter. Atab at the :forward end of the front is bentover the plow 13, as shown at 15, to fornran outerguide, over butspaced from the sides and upper edge of the plow 13, The forward ends of the front 10 and of the outer guide 15 are flared outwardly, as shown at 16; and 17 respectively, in Fig. 4L. This facilitates the insertion of the end of the plowbetween the folds of the papers which are to be separated.

The outer guide15. keeps the plow from be ng inserted to a depth to which it might in ure the contents ofthe envelop. The edge to be out runs between the inner and outer guides so that the natural tendency of the demos in use is to run parallel with the edge to be cut. I The manner inwhichthis device is used 1s obvious and may be seen at a glance from the inspection of Fig. 1. I haveshown what I consider a preferred form of, the device embodying this invention, but the. construction and form may be varied without departure from the spirit and. scope of this invention, and I intend no limitations other than those imposed by the. appended claims.

What I claim is:

1. A paper cutter comprising a back, a pair of parallel members joined together at the back, the first of said members being constructed to form an inner guide and a cutting edge curved upwardly to the back, and the second member terminating short of the end of the inner guide and having a tab bent over but spaced from the inner guide and forming an outer guide.

2. A paper cutter comprising a back, a pair of parallel members joined together at the back, the first of said members being constructed to form an inner guide and a cutting edge curved upwardly to the back, and the second member terminating short of the end of the inner guide and having a tab bent over but spaced from the inner guide and forming an outer guide with the inner guide projecting forwardly from said back and a cutting edge curved upwardly to the back and the second member terminating short of the end of the inner guide and having a tab bent over but spaced from the inner guide and forming an outer guide.

5. A paper cutter comprising a back, a pair of parallel members joined together at the back, the first of said members constructed to form a comparatively narrow inner guide projecting forwardly from said back and a cutting edge curved upwardly to the back and the second member having edges projecting beyond the corresponding edges of said first member and terminating short of the end of the inner guide and having a tab bent over but spaced from the inner guide and forming an outer guide with the forward edges of the guide flared outwardly.

6. A paper cutter constructed of a single piece of sheet metal comprising a pair of parallel members joined together to form a back, the first of said members constructed to form an inner guide and a cutting edge curved upwardly to the back and the second member terminating short of the end of the inner guide and having a tab bent over but spaced from the inner guide and forming an outer guide.

7. A paper cutter constructed of a single piece of sheet metal comprising a pair of parallel members joined together to form a back, the first of said members constructed to form an inner guide and a cutting edge curved upwardly to the back and the second member having edges projecting beyond the corresponding edges of said first member and terminating short of the end of the inner guide and having a tab bent over but spaced from the inner guide and forming an outer guide.

8. A paper cutter constructed of a single piece of sheet metal comprising a pair of parallel'members joined together to form a back, the first of said members constructed to form a comparatively narrow inner guide and a cutting edge curvedupwardly to the back and the second member projecting forwardly from said back and terminating short of the end of the inner guide and havinga. tab bent over but spaced from the inner guide and forming an outer guide and with the forward edges of the guide flared outwardly.

9. A paper cutter constructed of a single piece of sheet metal comprising a pair of flat. parallel members joined together to form a curved back with the outer surface of said back roughened, the first of said members being constructed to form a comparatively narrow inner guide projecting forwardly from said back and a cutting edge curved upwardly to the back and the second member having edges projecting beyond the corresponding edges of said first member and terminating short of the end of the inner guide and having a tab bent over but spaced from the inner guide and forming an outer guide.

10. A paper cutter comprising a back, a pair of parallel members joined together at the back, the first of said members being constructed to form an inner guide and a cutting edge between the guide and the back and the second member terminating short of the end of the inner guide and having a tab bent over but spacedfrom the inner uide and forming an outer guide.

In witness hereof, I hereunto set my hand this 27th dayof January, 1920.
