PENCIL AND ERASEE, THEEEFOR.

Application filed November 14, 1925.y Serial No. 68,951.

The object of the invention is to provide improvements in pencils and particularly in the erasers with which the average pencils are equipped. 4

5 The usual pencil has but a single lead and also a single piece of rubber,`or similar material, which serves while it lasts as means for removing or erasing marks made by the lead upon paper or the like. In practice it seems that the pencil manufacturers have endeavored to arrive at, and. attach to a pencil, a size of eraser which will last throughout the use of the major portion of the lead in the pencil, and will leave little or none of the rubber to be thrown away when the lead is' gone. As a result for many pencil users the amount of rubber supplied with a new pencil is not sufficient to last throughout the life of the lead and` as a result during the final stages 'in the use of the lead, frequently as much as half of said lead is not accompanied by the presence of any eraser whatever.

Therefore, another 'object is to provide a much larger piece of rubber than is usually supplied with-a pencil, but to so construct the eraser supporting structure as to expose only the desired amount of rubber at a time.

A further object is to provide this more extensive eraser for magazine pencils, in which .a large number of leads is adapted to be carried, and ,particularly in which case the usual eraser would be far from sufficient to supply even the average demand. In this instance, the eraser serves the additional purpose of forming a closure, or stopper, for the magazine in which the reserve supply of leads is kept.

And still another object is to provi most simple construction for 'supporting araf ex- 40 posing the eraser by degrees as its outer portion is worn away by constant usage, said construction comprising aferrule rotatably supported in threaded engagement upon the body of the pencil, and through the outer open end of which 'normally protrudes the serviceable end portion of they eraser, said ferrule also being operative when rotated outwardly to entirely cover the sides and protect the eraser against injury, or becomho ing dirty, when not in use.

i Further details in the construction and operation of the invention are'fully brought out in the following description, when read in conjunction with the accompaying drawings, in which Fig. 1 is a side elevation of one embodiment of the invention; Fig, 2 is a longiv threaded open end 8, into f'tudinal lsection of a fragmentary portion of the device taken on the line 2 2 of Fig. l; Fig. 3 is a section on the line 3 3 of Fig. 2; and Fig. 4 is a section on the line 4-4 Fig. 2.

Referring to the drawings, a magazine pencil is represented as comprising a body 1,having a tapered end portion 2, through which protrudes a writing lead 3, adapted to be replaced and adj ustably positioned by any suitable type of mechanism (not illustrated in detail). The body portion 1 .at the end opposite to the lead 3 comprises a shell 4, within which is centrally positioned a casing 5 whichincloses the lead-positioning mechanism, said casing and the surrounding shell being in uniform spaced relation, to provide a substantially cylindrical chamber 6 in which reserve leads 7 may be positioned or stored, and

from which suclr'leads may be removed as 'they are requiredi'for replacing the lead in.

operative position in the opposite end 2.

The shell 4 terminates in an .externally l which normally extends a reduced end the body portion 10l of which extends freely therefrom and' provides an exposed endvpor- Ation 1l, adapted to be employed for removing lead marks frompaper or the like in the usual manner. A ferrule, having an inter-y nally threaded body portion 12, normally in threaded engagement with the correspondingly threaded portion 8 ofthe shell 4, comprises a relatively short, smooth-bored end portion `13 surrounding the body 10 of the eraser, and a relatively longer, smooth-bored portion 14 extending slidably over the adjacent end portion of said shell, so as to protect `the threaded portion 8, to form an attractive adjustable covering for the magazine portion of the instrument, and to form a suitable sup port for any desired type of clip 15 employed to removably attach the said instrument to ones pocket, or the like.y

In using this improved writing instru- `ment, the pencil is manipulated in the usual manner to withdraw or expose the lead 3 as desired.

lVlien necessary to replace a worn lead by a fresh one, or to Isubstitute for one lead a second lead of a different color, the ferrule 12 is rotated outwardly until it is entirely free of the threaded portion 8 and can be removed from the eraser 10. The eraser itself is then removed from the chamber 6 so as to expose the reserve leads in the latter. The proper portion 9 of an eraser, v

opposite tapering end portion 2 of the pencil,

Aafter which the said eraser is replaced as a stopper for the storage chamber, and the :Eerrule 12 is replaced as shown in the drawings. Also, as the exposed end portion 11 of the eraser becomes worn away, this ferrule is rotated inwardly further and further upon the threaded portion 8 of the shell, in order to correspondingly expose more and more of the body 10 of the otherwise protected portion of the rubber.

Having thus described my invention, what I claim and desire to protect by Letters Patl ent of the United States is l An instrument of the class described coinprising a hollow container body provided with exterior screw' threads adjacent one end thereof, an eraser removably closing the body at said end, a ferrule surrounding said body and eraser, said ferrule having interior screw threads spaced from its ends and engaging the first mentioned screw threads so that the ferrule is adjustable longitudinally of the body to compensate-for Wear of the eraser,

said ferrule' at one end having a portion longer than and covering the screw threaded portion of the body and spaced outwardly from the body, the other end portion of the body being interiorly smooth, the last mentioned portion and screw threads of the :terrule being spaced outwardly from -the eraser.

ln testimony whereof l have afiixed my signature. A

MAURICE ALLAND.
