To @Zt whom, it may concern.-

Be it known that I, JOHN GAULT, of Boston, Suiolk county, Massachusetts, have invented a new and Improved Mode of Combining Pencil-Erasers and Eraser-Sharpeners in the Same Instrument; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and the letters of reference marked thereon, in which the same letter represents the same thing in each figure.

My invention consists in combining prepared india rubber, in the form usually adopted for erasing pencil -marks, with an Arkansas or other whetstone and any kind of leather suitable for strapping or giving a fine edge to steel. t

Figure I represents a side view showin g the hone A. Fig. 2 represents a side View showing thestrap B. Fig. 3 represents the edge. Fig. et represents a sectional cut view showing the houe embedded in the india-rubber and strap attached on the opposite side.

To enable others to make and use my iuvention, I will describe its construction.

Into an ordinary piece of prepared rubber, of size convenient for the counting-room, I embed a narrow piece of Arkansas or other Whetstone, and upon the other side of the rubber I permanently attach a narrow piece of leather suitable to sharpen a knife-blade. The rubber may be surrounded by a leather or any desired protection for the fingers, leaving the ends of the rubber free and the hone and strap both slightly elevated above the surface of both the rubber and leatheror other shield for the fingers.
