JOHN PALMER NACE, OF KANSAS CITY, MISSOURI.
EBASING ATTACHMENT FOR WRITING INSTRUMENTS.
Application filed Februaly 16, 1914.
To all whom it may concern:
Be it known that I, JOHN PALMER NACE, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Erasing Attachments for Writing Instruments, of which the following is a specification.
My invention relates to improvements in erasing attachments for writing instruments, such, for instance as lead pencils, pens and the like, and my object is to provide a simple, inexpensive device of this character, which, when applied to the end of the instrument will be ready for use in erasing ink or lead pencil marks.
In order that the invention may be fully understood, reference will now be made to the accompanying drawing, in which:
Figure 1 is a side elevation of the attachment applied to a lead pencil. Fig. 2 is a longitudinal section of the device, enlarged, on line IIII of Fig. 1. Fig. 3 is a detail elevation of the device, enlarged, with the hood thereof removed. Fig. 4 is a cross section on line IVIV of Fig. 3. Fig. 5 is an end elevation, enlarged, of the device in position upon a pencil.
A designates a writing instrument in the form of a lead pencil containing the usual rubber-tip B, secured thereon with the customary tubular connection C.
1 designates a split sleeve constituting one of the features of the present invention. Sleeve 1 has a slot QeXtending longitudinally thereof to render said sleeve resilient, so that it may be made to firmly grip the pencil by means of an annular clampingmember 3 slidably mounted upon the sleeve, which has a tapered shoulder 4 that coacts with the clamping-member 3 in causing the sleeve to firmly grip the pencil. The attachment can be readily removed when desired by shifting the clamping-member 3 out of engagement with the shoulder 4:, and thus permitting the sleeve to release its grip upon the pencil. The clamping-member 8 is preventedfrom being pushed off the rear end of the sleeve 1 by means of a marginal bead 5 on the rear end of said sleeve.
6 designates an annular blade mounted Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

eral beads 8 and 9,'the former being located at the forward end of sleeve 1 and the latter at the rear side of the rubber eraser 7. Blade 6 and the rubber eraser 7 are, preferably, of the same diameter, so that they may be simultaneously employed in marks. The rubber eraser 7 is, preferably, of the sand rubber or abrasive type to render it more effective in erasing ink from paper.
10 designates a clamping-member slidably mounted upon the sleeve 1 and provided with an integral annular hood 11, to be slipped forward over blade 6 and the rubber eraser T, as shown on Fig. 2, preparatory to carrying the pencil in a coat, or vest pocket. The clamping-member 10 is caused to firmly grip the sleeve 1 and thus reliably hold the hood 11 in position over blade 6 and the rubber eraser .7, by means of a tapered shoulder 12 on said sleeve.
From the foregoing description, it is apparent that I have produced a simple, in-
expensive device embodying the features.
of advantage above enumerated, and while I have shown and described the preferred form of construction, combination and arrangement of parts, I reserve the right to make such changes as properly fall within the spirit and scope of the invention as defined by the claim.
Having thus described my invention, what I claim and desire to secure by Letters Pate ent,is:
In combination with a writing instrument, a sleeve mounted upon the handle of said instrument, a blade mounted upon said sleeve, a hood to slip over said blade, a clamping member carrying said hood, and
a tapered shoulder on the sleeve coacting with said clamping member to secure the same from accidental movement.
In testimony whereof I aifix my signature, in the presence of two witnesses.
