,PENCILAND ERASER Filed March 26, 1938 Patented Oct. 11, 1938 PATENT OFFICE PENCIL AND ERASER Arthur W. Forsyth, Maplewood, Mo., assignor to Wallace Pencil Company, St. Louis, Mo., a corporation of Missouri Application March 26,
4 Claims.
My invention relates to the mounting of erasers on the ends of pencils and'has for its principal objects to provide a larger eraser, to improve the appearance of the eraser end of the pencil, to mount the eraser more firmly in place and to accomplish other objects and advantages that will be hereinafter pointed out.
The invention consists principally in fixing on the end of a pencil a metal ferrule having a portion of reduced diameter, which extends into a recess in a rubber eraser, the tip of said ferrule having rebent hooks or barbs that securely fasten the eraser and ferrule together.
In the accompanying drawing,
Fig. l is an elevationof a pencil and eraser construction embodying my invention; and a Fig. 2 shows the eraser in longitudinal section, with a portion of the ferrule cut away to show the ferrule partlyin longitudinal section.
The drawing illustrates a portion of a pencil A of the well-known hexagonal type. Mounted on the end of said pencil is a metalferrule B. The
metal ferrule B includes a portion 1 of substantially the same outside-diameter as the pencil, said 5 5 portion being given any desired ornamental finish as shown by the ribs 2 and knurls 1 3 of the drawing.
The ferrule B has an elongated cylindrical porduced portion 4; and the ferrule is secured tothe wooden barrel by stamping or punching portions 6 5 of the ferrule into the-barrel.
At its outer'end the ferrule Bis provided with barbs or prongs 1' that are rebent into proximity with the outer surface of the ferrule. A rubber eraser 8 having an axial recess 9 whose. depths is equal to the distance from the outermost rib to the end of the ferrule is forced over the cylindrical reduced portion 4 of the ferrule, into abutment with said outermost rib 2. The recess 9 has an inside diameter such as to fit snugly on the reduced portion 4 of the ferrule andthe prongs or barbs l of the ferrule will dig into the eraser material to prevent withdrawal thereof.
1938, Serial N6. 198,199 (01. 120-38) The above described construction makes possible the use of an eraser of any desired size, the amount of eraser material available for erasing being obviously much greater than in the case of an ordinary eraser mounted inside a metal ferrule. The eraser is more firmly supported than ordinary erasers, by reason of the depth to which the ferrule extends into the eraser and the wooden barrel of the pencil extends into the ferule- The unsightly punches usually required to secure the ferrule to the penciland to secure the eraser inside the ferrule are eliminated, the only punch marks being concealed by the eraser. The eraser can obviously be given a square or other desired shape without sacrificing its stability on the pencil.
What I claim is:
l. A pencil having a hollow ferrule mounted thereon and an eraser mounted on said hollow ferrule, said ferrule having rebent prongs holding the eraser inplace.
2. A pencil and eraser construction comprising a pencil, a hollow metal ferrule mounted on the end thereof having a projecting cylindrical portion and an eraser having an axial recess re-- ceiving said projecting portion of said ferrule,
said ferrule'having rebent prongs at its outer end preventing removal of the eraser.
3. A pencil and. eraser construction comprising a penciL-a hollow metal ferrule mounted on the end thereof having a projecting cylindrical portion of reduced diameter and an eraser having an axial recess receiving said projecting portion of said ferrule, said ferrule having rebent prongs at its outer end preventing removal of the eraser.
4. A pencil and eraser construction comprising a pencil, a hollow metal ferrule mounted on the end thereof having a circumferential rib and having a cylindricaljportion of reduced diameter projecting beyond said rib and an eraser having an axial recess receiving said projecting portion of said ferrule, the end of said eraser being seated against said rib, said ferrule having rebent prongsat its outer end preventing removal of the eraser.
