UiECIFI-CATION forming part of Letters Patent No. 306,882, dated October 21, 1884.
Application filed January 31, 1884.
To all w/wm/ it may concern:
Be it known that I, CHARLES S. WATsoN, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in a Combined Envelope-Opener, Eraser, Pencil-Sharpener, and Paper-Cutter, which improvement is fully set forth in the following specification and accompanying drawings, in which-- Figure 1 is a side elevation of an envelopeopener, eraser, pencil-sharpener, and papercutter embodying my invention. Figs. 2 and 3 are edge views thereof.
Similar letters of reference'indicate corresponding parts in the several figures.
My invention consists of an implement embodying an envelope-opener, eraser, pencilsharpener, and paper-cutter, as will be hereinafter fully set forth.
Referring to the drawings, A represents a plate or blade of steel,which is shaped at one end to form a handle, as at B, one edge thereof extendingin aright line, as at G. The end of the blade opposite to the handle Bis reduced and pointed,one edge,D, of the point being rounded outwardly and sharpened, the other edge, E, being rounded inwardly and partly sharpened. Adjacent to the sharpened edge E is a sharpened edge, F, between which and the edge E is a projecting peak, G, the outer end of which is blunt, as at a. The portion of the edge E near the point is blunt, as at b, and the remaining portion is sharpened to the peak G. It will be seen that the right line edge 0 produces a convenient paper-cutter, the implement being laid on the paper and the latter (No model.)
torn along said edge C. The edge D provides an eraser, the edge E an envelope-opener, and
the edge F a pencil-sharpener, either of which point thereof is inserted between the parts 0f the envelope, the edge E being toward the fold to be out. When the implement is moved, the edge E cuts said fold, and as the blunt part b is in advance the point of the implement is prevented from cutting through the fold, and'thus the point is retained within the same, leaving the edge E to perform the cutting operation with facility and certainty, it being evident that the edge F may also be used as a paper-cutter as well as an envelopeopener.
Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is 1 A plate having a handle at one end, and at the other end a point sharpened on both edges, and adjacent thereto an additional sharp edge, forming a combined eraser, envelopeopener, and pencil-sharpener, as stated.
