TAILORS CRAYON-SHARPENER'.

TO ALL PERSONS TO WI-IOM THESE PRESENTS MAY COME:

' Be it known that we, BENJAMIN lW. MINOR and ALLEN CoLBUnN, of Boston, in the county of Suffolk, and State of Massachusetts, have invented a 'new and useful Tailors Crayon or Chalk-Sharpener; and do hereby declare the same to he fully described in the following specification, and represented in the accompanying drawings, of which- Figure 1 is a top view.

Figure 2 is a sido elevation.

Figure 3, a longitudinal section; and

Figure 4 is a transverse section of'it.

This invention answers not only as a weight to hold the cloth or pattern in place, and a means of sharpening a piece of crayon, but as a device for intercepting dust or waste cut from the crayon, and preventing it from getting upon the floor, bench, or dress of an operative- In the drawings, A denotes a flat and heavy base or weight, surmounted by a cup, C, the latter serving as a handle to the weight, by which it may be raised as occasion may require.` AAcross the cup the cutter or cutters are arranged, the same consisting of-a tube, a, and a thin blade o-r bar, b, heated and braz'ed together, the blade being extended diametrieally across the tube and projected in opposite direction from it. The bar and the tube have V-shaped notches made in them, as-shown at efy, each serving as a means of reducing the crayon plate of chalk to a sharp edge, the chips or powder being caught by and in the cup. The weight, besides answering the purpose above mentioned, serves to keep the 'sharpening-knives steady during the process of sharpening the crayon, the form of which is given in side view in Figure 5, and in end view in Figure 6. The 'niode of making "the cutter is advantageous, it being better than a single blade, as it serves to4 steady the crayon While in the act of being cut, and causes itto be cut with a straight edge.

Heretofore, in sharpening a cra-yon, it has been customary for the tailor to accomplish it with or by means of a penknife, and by scraping or cutting it down on its opposite sides. This process causes the dust or shavingsl to gather upon his fingers or clothes or adjacent articles, much to hisinconvenience; but with our invention he has only to draw the crayon through the notches of the cutter, the dust removed being caught -in the cup. By our invention a crayon can be much more expeditiously and better sharpened than by av penknife used in the common and well-known manner. v

We claim, as our invention, the cutter, as composed of the cross-har and tube, arranged and slotted as described.

We also claim the combination and arrangement di' the cutter and the waste intcrcepting-cnp.

We also claim the combination and arrangement of the cutter, the'waste intercepting-cup, and the base or Weight, the whole being as and for the purposes described.

. BENJAMIN W. MINOR,

ALLEN COLBJURN.
