- ERASER- ATTACHMENT FOR LEAD PENCILS Filed June 19, 1926 INVENTOR Patented Apr. 11,. 1933 UNITED STATES PATENT OFFICE TDUIS J. RECKFORD, OF NEW YORK, N. Y.; LOUISE KING RECKFORD, JOHN KING BECK- FORD AND LOUIS J'. GRUMBACH, EXECUTORS AND TRUSTEES OF SAID LOUIS J.
RECKFORD, DECEASED, ASSIGNORS TO AMERICAN LEAD PENCIL COMPANY, OF
HOBOKEN, N EW JERSEY, A CORPORATION OF. NEW YORK ERASER ATTACHMENT FOR LEAD IPENCILS Application filed Tune 19,
This invention relates to improvements in rubber eraser attachments for lead pencils.
One object of the invention is to provide an eraser attachment for lead pencils such that the eraser will have a much longer lifetime than the circular rubber tip ordinarily used heretofore,- a lifetime approximating that of the pencil itself, and to'accompllsh this result without the employment of adj usting devices for the rubber tip and without departing from the preferred cylindrical form of the latter.
A further object of the invention is to provide an eraser attachment of the above character which is adapted to furnish a maximum surface for erasing written or other matter with a minimum effort.
A further object is to provide an eraser attachment of the above character, simple in construction and producible at low cost, and in such form that it will not encumber or interfere with the use of the member to which it is attached.
These and further objects will be apparent from the following description, when considered in connection with the accompanying drawing, in which one embodiment of the invention is illustrated.
Referring to the drawing, Figure 1 is a perspective View; Fig. 2 is an elevation; and Fig. 3 is a longitudinal section.
In the drawing, the pencil with which the improved eraser attachment is associated is shown in dotted lines and indicated by reference numeral 5.
A ferrule is attached to the upper end of the pencil 5, and this ferrule comprises two chamber portions which are of different diameters, said chamber portions being concentric to a common axis and being connected by an annular shoulder 10, thereby forming an integral ferrule. The lower portion 6, which is ofsmaller diameter than the upper portion 7 embraces the top of the pencil 5 in a tight-fitting manner so that its rotation on the pencil is prevented. The length of the chamber portion 6 is sufficient to hold the ferrule securely in position on the pencil. i
For the purpose of presenting a smooth 1926. Serial no. 117,014.
and uniform surface between the pencil and the ferrule, the top of the pencil may be which is of greater diameter than the portion 6, serves to hold an eraser 8 in position. The length of the wall of the chamber portion 7 is suflicient to prevent the displacement of said eraser by providing enough support therefor so that it will not become dislodged by any lateral strain while it isbeing used. The annular shoulder 10 intermediate the chamber portion 6 and chamber portion 7 not only serves to unite those chambers, which are of substantially different diameters, into an integral ferrule, but serves also the purpose of more securely seating the eraser, and limiting its entrance into the chamber portion 7. The wall of the chamber portion 7 may be provided with a smooth bore or have screwspun threads provided in its surface, as indicated by the numeral 9. For the purpose of insuring the retention of the eraser 8 in its container 7, cement or other adhesive may be employed; it being a feature of the present invention that the eraser be permanently set in its container and that no adjusting means therefor be provided.
It will be obvious that, by means of the eraser attachment constructed as above described, it is possible to provide, in a simple and effective Way and at minimum cost, a rubber pencil tip which will last as long as the useful lifetime of the pencil itself, and that-it is possible thereby to achieve this long sought result without the use of adjusting devices and without departing from the preferred circular form of rubber.
It will also be obvious that by means of the improved arrangement, a maximum surface is provided which will permit the erasure of.
written matter with a minimum effort and without any interference with the function of the pencil or other member with which it may be associated.
From the foregoing, it is thought that the construction, operation and manyadvantages of the herein described and delineated invention will be apparent to those skilled in the 5 art without further description, and it will be understood thatvarious changes in the size, shape, proportion and minor details of construction may be made without departing from the spirit or sacrificing any of the advantages of the invention.
What is claimed is:
An article of manufacture consisting of an integrally formed ferrule whose wall is approximately concentric throughout to acom- 15 mon axis and which comprises anannular shoulder at the middle portion thereof, -a pencil receivin portion of relatively small diameter exten ing from said shoulder in one direction and an eraser receiving portion of 20, substantially larger diameter extending from said shoulder in the opposite direction; a pencil one extremity of which fits within said pencil receiving portion of said ferrule, being closely embraced by the wall thereof and permanently and immovably secured therein; and an eraser of substantially larger diameter than said pencil secured within and closely embraced by the wall of said eraser receiving portion of said ferrule and extending substantially beyond the outer extremity thereof.
In testimony whereof, I have signed my name to this specification this sixteenth day of June 1926.
LOUIS J. RECKFORD.
