AUSTIN D. HOFFMAN, OF CHICAGO, ILLINOIS.
SPECIFICATION forming part of Letters Patent No. 310,513, dated January G, 1885.
To @ZZ whom it may concern:
Be it known that I, AUsTrN D. HOFFMAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Paper-Cutters, which are set forth in the following specification, reference being had to the accompanying drawings, in Which- Figure l is a plan view of my invention; and Fig. 2 is a section of the same, taken on the line x x of Fig. 1.
My invention relates to paper-cutters such as are ordinarily made of sheet metal and sold by Stationers.
lVIy invention consists in such a paper-cutter having an adjustable slide provided with figures, which, in combination with certain marks, letters, and index, make the papercutter equally useful as a perpetual calendar.
In the drawings, A represents the ordinary sheet-meial papercutter. Upon this cutter are stamped a sufficient number of the days ofthe week to make a month, as shown at B.
C is a slide secured to the paper-cutter A by means of the headed rivets D, Vwhich pass through slots E in the paper-cutter A.
There are figures from l to 31, numbering the days in a calendar month, spaced on the slide corresponding tothe spaces occupied by the names of the days of the Week on the paper-cutter A. The slide C is so attached to the paper-cutter that it can be adjusted so as to bring the figure 1 on the slide opposite either of the first seven names of the days of the week, so that the ligure l on the slide can be set opposite the day of the week which happens to be thc first day of the month.
F is a pointer pivoted to the paper-cutter A by the headed rivet G. The names of the months constituting a year are stamped on the paper-cutter Ain the arcof a circle, as shown, in such relative positions to the pivot of the pointer or index that it can be turned on its pivot and point to either oi them, as shown.
I are holes through the paper-cutter, into which the point of the pointer springs as it is turned to point to the month. It is necessary to change this point each month, so that during each month it will point to the month of the year. It is necessary, also, to adjust the slide C each month so that the iigure'l on the slide will stand opposite the name of the day of the week which was the first day of the month. The paper-cutter then, which always remains accessible on ones desk, presents a calendar Vduring that month. On the first of the next month the pointer should be adjusted and the slide C be adj ust ed as above described. By these simple adjustments I have a perpetual calendar and a paper-cutter.
H are lines stamped on one side of my paper-cutter, at right angles to its edge, one inch apart. The spaces between these lines I di vide into halves, quarters, and sixteenths by stamping the lines on the paper-cutter, as clearly shown, making a rule on one edge of the papercutter,as clearly shown in the drawings hereto annexed.
I not only can use my paper-cutter, which4 is always conveniently at hand7 for measuring or spacing paper and other articles, but also for a paper-cutter and a calendar.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
The paper-cutter A, bearing near one end the arc-shaped series of names and the pivoted pointer F, and having marked upon it the longitudinal weekday column B, in combination with the slide C, having marked upon it a corresponding month-day column, substantially as and for the'purposes described.
