` UNITED ASTATES VILLIAM C. VOSBURGH AND VIIlLIAM A. LUDDEN,
PATENT OFFICE.
or BROOKLYN, NEW
YORK. l
Specification forming part oli Letters Patent No. 35,355, dated May 20, 186.2.
T0 all whom, it may concern:
Be it knownthat we, VILLIAM C. Vos- BURGH and WILLIAM A. LUDDEN, of Brooklyn,
in the county of Kings and State oli New York,
have invented, made, and applied to use a certain new and Improved Means for Attaching Rubber to Pencils, dac. and we do hereby declare that the following` is a full, clear, and exact description oi' the said invention, reference being had to the annexed drawings,
making part of this specijfcation7 whereinh Figure l is an elevation of a pencil with our improved means for attaching the rubber applied thereto; and Fig. 2 is a vertical section of the same.
Similar marks of reference indicate Athe same parts. Small circular pieces of rubber have heretofore been attached to a pencil or pen-handle by dressing down the end and entering the same with suitable'cement into a hole formed in the rubber. rlhis involves the necessity oii' forming the rubber exactly as required for said use.
Our invention consists in the employment of semi-cylindrical clamps, and a ring or rings to bind said clamps upon both the pencil and the p rubber, so that said rubber can be projected more or less from said clamps, and the ordi nary gum-elastic cord can be employed, by
cutting the same off in sections of the desired length, thus affording great facility in applying the rubber to a pencil orpen-handle, allowing for the introduction of a new piece when necessary, and sustaining the rubber While being marks.
employed for erasing pencil.
In the drawings, a is a pencil or a pen-handle.
l) Y) are the semi-cylindrical clamps of metal or other suitable material.
c is the section of gum-elastic, and (Z (Z are rings of metal or other material slid over the pair of semi-eylimlrical clamps to bind them to the rubber and to the pencil orpenhandle respectively.
The semi-eylimlrieal clamps should, for convenience in manufacturing, be both alike and of a size to form, when settogether, a cylinder slightly less than the smallest size of pencil or pen -handle to which they are adapted; hence there will be a slight separation between these clamps, as shown in Fig. l, with the ordinary sizes of pencils or pen-handles. The rings d d must be varied in size to suit the pencil, or but one ring might be eml ployed, if desired.
\Vhat we claim, and desire to secure by Leliters Patent, is-
The employment of the clamps b Z2, formed as specified, and a ring or rings, CZ, in combination with the section of india-rubber c, and the pencil or pen-handle a, for the purposes, and as set forth.
In Wit-ness whereof we have hereunto set our signatures this 18th day ot' April, 1862.
WM. C. VOSBURGH. WM. A. LUDDEN.
