SPECIFICATION forming part of Letters Patent No. 445,092, dated January 20, 1891.

Application filed December 5, 1890. Serial No. 373,65 1. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM E. SIMONDS, a citizen of the United States of America, residing in the town of Canton, county of Hartford, and State of Connecticut, have invented a certain new and useful Improvement in Erasers, of which the following is a description, reference being had to the accompanying drawings, wherein- Figure 1 is what may be termed a flatwise view of a device embodying said improvement. Fig. 2 is an edgewise view of the same device. Fig. 3 is a view in section on the plane :r, on an enlarged scale.

The improvement pertains to an ink-eraser making use of a removable strip of erasive material, which is to be thrown away when used up and a fresh strip substituted.

The essential elements of the improvement are, first, a stock of such shape that, in conjunction with a properly-shaped sleeve, it may be made of a material (such as hard wood, for instance) not specially elastic diametrically; second, a pliable and removable erasive strip, and, third, a sleeve which hides the ends of the strip from sight, which keeps the ends of the strip out of hurtful and accidental contacts with other things, and which, through its approximation in shape with the shape of the stock both diametrically and longitudinally, holds the strip and itselfupon the stock.

Premising that by what follows I do not intend to exclude from the province of my improvement such mere changes of form as embody the essentials just stated,l will describe and claim a device wich embodies my impro vement.

The letter a denotes a stock, preferably of some suitable hardwood, with sides that converge gently toward each other, so that it may be not inappropriately termed wedgeshaped, and this stock is provided with a handle 1), whereby to grasp and use the device.

The letter cl denotes a pliable erasive strip, by preference a piece of emery-cloth, which is folded over the end of the stock and held in place by means shortly to be described. \Vhen the strip is used up, it is thrown away and a new one substituted. If the sides of the stock be shouldered and the ends of the strip abutted against the shoulders, as seen in Fig. 3, the strip will thereby be prevented from shifting in position on the stock.

Theletter 0 denotes a metallic sleeve, which is wedge shaped in the same general sense that the stock is, and to a degree its shape approximates, both diametrically and longitudinally, the shape of the stock. Gently forced to its seat on the stock it holds the strip and itself in place on the stock; it hides the ends of the strip from sight; it keeps the ends of the strip outof accidental and hurtful contact with other things, and it permits such a shape of the stock that the stock can be made of a material not specially elastic diametrically. Itis permissible, but not necessary, to give the ends of the sleeve a springlike action by means Of slits c.

I claim as my improvement- In combination, the wedge-shaped stock a, the wedge-shaped sleeve 0, and the pliable erasive strip cl, all substantially as described, and for the purposes set forth.
