nimsrvn MEANS fort WRITING IMPLEMENTS.

Application flied June 4,

To all whom it may concern:

Be it known that I, ALFRED VEILLETTE, a citizen ofthe I United States, residing at Attleboro, in thevcounty of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Erasive Means for Writing Implements, of which the following is a specification.

invention relates to improvements in Writing implements. i

Formerly, when a writing implement such as a pencil has been used, whenever a mistake has been made anderasive means are needed, it has been necessary eitherto lay? down thepencil and to pick iupa separateeraser, or to. turn the pencil around and use the eraser 'whichis often placed on the opposite end of the pencil from the writing point. Much time is actually lost in changing from the writing. to the erasive means.

One object of my invention is to provide a writing implement with the eraser on the same end as the writing point, said eraser being adapted to slidably telescope the writing: point by a slight movement ofvone of the fingers while writing. My invention thus renders itpossible to erase any errors made in writing with practically the same movements used in writing, after merely pushing down the slidable eraser with a 'fingier already in convenient position therefor. Then the slidable eraser may be pulled up with a similar slight .niovement of the finger, and the writing continued with practically the Mistakes in writing naturally occur, and erasing is a necessary step in the art of writing cor rectly. It is obvious, therefore, that my invention-efi'ects a great improvement in the art of writing by. permitting the writer to write correctly with the same implement held in the same position with approximately the same movements used in writing.

A further object of my invention is to provide means to protect the writing point when not in use.

A further obj ect of my invention is to provide an eraser retaining means in which eraser's are readily replaceable as worn out.

A further object of my inventionis to pro vide a writing implement such as a fountain pen, mechanical pencil, &c;, of improved. construction wherein the erasive means is in tegrally' built into the implement, or erasive attachment of improved construction 1923. Serial No. 643,253.

for other types of writing implements such as ordinary pens, pencils, &c.

These and such other objects of my in-;

vention' as may hereafter appear may be best understood from a descriptionof the accom panying drawings which illustrate my invention adaptedto different types of pencils.

In the drawings, Fig. 1, is .a side elevation of'a mechaniealpencil with the eraser holder integrally built therein.

Fig. 2 is a'longitudinal seotiontaken along the lines 22 of Fig. 1,,showing the eraser retracted from the pencil point. f

Fig. 3 is a view similar to Fig. 2, showing the eraser telescoping the pencil point.

Fig. 4 is a perspective view of the eraser holding member. r

Fig. 5 is a longitudinal sectional View of a modified form of my invention for an or dinary pencil shownin position thereon.

Fig. 6 is a longitudinal sectional view of the modified form.

In the drawings, wherein like characters of reference indicatelikeparts throughout, 1 represents an ordinary mechanical pencil with the usual outer shell 2, turning cap 3', lead advancing tube 4 and-lead writing point 5.- Atthe writing end of the pencil I'loosely insert the tube '8 within the shell 2, thus permitting the tube 8 to slide axially therein. I'provide the tube 8 with a longi-- tudinal slot 9 to limit the axial movement thereof. A screw 10 is threaded through the outer shell 2. The inner end of said screw 10 is adapted to register in said slot 9, and contacting the endsof said slot, limits the inward and outward movement of said tube 8. For ornamentation, a ring 12 with a bead 13 at its outer end may encircle thetube 8, as shown. Any convenient means may be employed for holding the eraser in the outer end of said tube 8. In the em= bodiment shown, I provide the tubular holder 14, having a tubular inner end 15 adapted to be securely forced into the outer end of the tube 8, and a tapered outer end 16 provided with longitudinal slots 17 extending fromthe outer end thereof at diametrically opposite points on the periphery thereof to provide resiliency therefor. An annular pocket 18 is thus formed between the inner periphery of the outer end 11 of said tube 8, and the tapered resilient outer end 16 of the eraser holder 14. An eraser 20 having abore21 converg= ing toward the outer end thereof is specially provided. The inner annular end 22 of said eraser is adapted to be forced into the annular pocket 18 and the resilient outer end 16 of the eraser holder 14 tending to stretch outwardly, retains it in position thereon.

In Figs. 5 and 6 I have shown a modified form of my invention. It comprises an attachment for an ordinary pencil, all the parts being identical to the parts already described except the shell 2. The shell 2 is made long enough to conveniently enclose the tube 8 when it is retracted to expose the pencil point 5. The shell 2 is constricted at the point of innermost withdrawal of the tube 8 and only extends far enough inward therefrom to provide means to slidably attach my invention to the ordinary pencil 1. Short longitudinal slots 25 are cut in the inner end of the shell 2 to permit the constricted inner end 26 to be resiliently adjustable on the pencil 1.

The operation of my invention is obvious from the above description. Either the mechanical pencil 1 or the ordinary pencil 1 is held in writing position as in Figs. 1, 2, or 5. A finger, usually the forefinger, normally rests against the tube 8. When .a mistake is made in writing, the finger is pushed down against the tube 8, or in the embodiment shown the bead 13 thereon. This causes the tube 8 to slide axially of the shell 2 until the screw 10 abuts the upper end of the longitudinal slot 9, limiting the outward movement of the tube 8. The hollow eraser holder 14 and eraser 20 mounted thereon thus telescope the writing point 5, and the implement 1 is in such a position that the erasure may be made with practically the same movement used in writing. (Fig. 3). lVhen this is completed the forefinger is raised up, and pressing against the beaded tube 8 causes the tube to return to the position shown in Fig. 2, the screw 10 abutting the lower end of the longitudinal slot 9, limiting the inward movement of the tube 8 and the tube 8 automatically pulling back the eraser 20 and freeing the writing point 5 which is still in a position for further writing. It is obvious that the pointed pencil end 5 will readily and compactly fit within the pencil holder 14:. When a pencil is employed, as it becomes shorter in length the shell 2 may be pulled up on the pencil, the resilient end 25 thereof retaining it in posit-ion thereon. New erasers 20 may be inserted in the holder 14 as the old ones wear out. It is obvious thatl have provided a simple compact device which effects a great improvement in the art of correct writing.

It is understood that my invention is not limited to the specific embodiments shown and that various deviations may be made therefrom without departing from the spirit and scope of the appended claims.

What I claim as new and desire to secure as Letters Patent is:

1. In a writing implement, the combination of a shell, a tube axially slidable relative to said shell having a longitudinal slot therein, a member securely attached to said shell registering in said slot to limit the axial movement of said tube, a hollow eraser holder mounted in the outer end of said slidable tube, and a hollow eraser mounted therein, said tube and eraser being posi tioned relative to the writing end of said implement to telescope said end when desired.

2. In a writing implement, the combination of a shell, a hollow eraser holder mounted on and slidable relative to said shell and limited in its slidable movement thereby, and a hollow eraser mounted on said holder, said holder and eraser being positioned relative to the writing end of said implement to telescope said end to permit the I eraser to function as desired whenthe im plement is held in writing position.

3. In a writing implement, a hollow eraser holder with a hollow eraser mounted there on attached to said implement to permit the writing end thereof to function and slidable on said implement to telescope the writing end thereof as desired to permit the free lower end of said eraser to function when the implement is held in writing position.
