COMBINED ERASER AND CALENDERING DEVICE.

SPECIFICATION forming part of Letters Patent No. 715,770, dated December 16, 1902- I Application filed July 28, 1902. Serial No. 117,268. (No model.)

1'0 all whom it may concern:

Be it known that I, PHILIP W. EDWARDS, a citizenof the United States, residing at Portland, in the county of Cumberland and State of Maine, have invented certain new and useful Improvements in a Combined Eraser and Calendering Device; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in a combined eraser and recalendering device.

As is well known, when the surface of paper is defaced by the use of an eraser it becomes necessary to recalender the surface before writing can be done upon the same surface without the ink spreading.

The object of my invention is to provide with the eraser a means of recalendering the surface. To this end I form on one side of the handle end of the eraseracurved projection and upon the opposite side an index-finger-receiving recess. In order to bring the bearing-point of the finger directly over the contact-point of said projection when in use, I locate the recess a slight distance from said projection toward the eraser, for the reason that when in use as a calendering device the eraser end is elevated a considerable distance above the surface of the paper, whereby the pressure of the finger is exerted in a direct line passing through said recess and the contact-point of the projection. In order to insure the contact-point being always in proper position relative to said recess, I further form said projection in a longitudinal direction, with two curves at and a, the one a nearer the eraser having the arc of acircle of greater diameter than the other.

The eraser and calendering device may be made of a single piece of metal, the eraser A being at one end and the projection B and recess 0 formed in the opposite end, or the eraser may be provided with a handle having the calendering device and recess formed therewith.

In the drawings herewith accompanying and forming a part of this application, Figure 1 is a plan view of the recess side of the device. Fig. 2 is a central longitudinal sectional view of the same, and Fig. 3 isatransverse sectional view of the same.

Same letters of reference refer to like parts.

Having thus described my invention and its use, I claim- 1. In a combined eraser and calendering device, an eraser having-at the opposite end on one side thereof a curved projection and on the opposite side a finger-receiving recess spaced apart toward the eraser relative to said projection.

2. In a combined eraser and calendering device, an eraser having at the opposite end on one side a projection formed of two curved surfaces, the one near the eraser being the arc of a greater circle than the other, and in the other side a finger-receiving recess situated substantially opposite said projection.

In testimony whereof I affix my signature, in presence of two witnesses, this 24th day of July, 1902.

PHILIP WV. EDWARDS.

In presence of- ELGIN O. VERRILL, MARION RICHARDS.
