ERASEB. ATTACHMENT FOR PENCILS.
Specification of Letters Patent.
Patented Dec. 28, 1920.
Application led October 4, 1920. Serial No. 414,601.
T 0 all whom it may concern:
Be it known that I, GEORGE C. HUNTER, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Eraser Attachments for Pencils, of which the following is a specification.
This invention relates to an eraser attachment for pencils, and has for its object to provide improved means for attaching an eraser to a pencil and adjusting the same so it can be used when desired, the attachment being eifected by means of a pinion or gear which engages the rubber to advance or retract the same. rThe device also serves as a clip for holding the pencil in the pocket.
The device will be more particularly understood from the following description and the accompanying drawings in which Figure l is a front view of a pencil provided with the device. Fig. 2 is a side elevation partly in section. Fig. 3 is a section on the line 3-3 of Fig. 2.
Referring specifically to the drawings, 6 indicates a lead pencil to which the device is applied. The device comprises a circular clip part 7 which fits over the pencil, the clip being split and the parts connected by a screw 8 by which it may be tightened and heldon the pencil. At the front side the clip is joined to a tubular casing 9 in which the rubber 10 is mounted to slide. This casing may be round or square according to the type of rubber used. At the front side, near the upper end, the casing is provided with an extension o'r housing 11 within which is a rack wheel or pinion 12 the teeth of which engage the rubber. This wheel is mounted on an arbor 13 which extends through the housing 11 and is provided with a head 14 by means of which the pinion may be turned. A nut 15 is screwed on the end of the arbor 13 to hold same in place, and to tighten the rack wheel so it will not turn.
By turning the wheel 12 by the means described the rubber 10 can be advanced or retracted. Particularly it will be advanced as it becomes worn. 1t may also be noticed that the inner end of the rubber is spaced from the pencil as indicated at 16, so that it forms a clip which will receive the edge of the pocket when the pencil is placed therein, and so will serve to retain the pencil in the pocket, the friction of the adjusting rubber preventing accidental dislodgment. It is intended that the device will last a considerable time, and it can be changed from one pencil to another, as desiret.
I claim:
1. An erasure attachment for pencils comprising a holder provided with a clip adapted to fasten the same to a pencil, an eraser slidable in the holder, and a pinion carried by the holder and engaging the eraser and adapted to be turned to advance or retract the eraser.
2. An erasure attachment for pencils comprising a tubular holder provided with means to attach the same 'to a pencil, an eraser slidable in the holder, and a toothed wheel mounted in the holder and engaging the eraser and adapted to be turned to advance or retract the same.
3. An erasure attachment for pencils comprising a tubular holder provided with a clip at one side thereof, said clip adapted to engage a pencil, an eraser slidable in the holder, and means engaging the eraser to advance or retract the same.
4l. An erasure attachment for pencils comprising a clip adapted to engage the pencil, a holder attached to the clip at one side thereof, an eraser slidably mounted in the holder and extending inwardly beside the pencil to form a pocket clip, and means to advance or retract the eraser.
5. An erasure attachment for pencils comprising a tubular holder provided with a clip for attachment to a pencil, said holder having a housing at one side thereof, an eraser slidable lengthwise in the holder, a toothed wheel in the housing engaging the eraser to advance or retractthe same, and means to turn the wheel.
1n testimony whereof, I aiiix my signature in presence of two witnesses.
GEORGE C. HUNTER.
