LEAD-PENCIL ATTACHMENT.

Specification of Letters Patent.

Patented Sept. 3, 1907.

Application filed October 11, 1906- Serial No. 338,377.

To all whom it may concern:

Be it known that I, OSCAR MUSSINAN, a citizen of the United States, residing at Arverne, in the borough of Queens, New York city, New York, have invented an Improvement in Lead-Pencil Attachments, of which the following is a specification.

My present invention relates to a lead pencil attachment or pencil point protector, and the object thereof is the provision of a simple, practical and inexpensive device, by the employment of which, the pencil point may be protected when not in use, and with which at the same time, the user of the pencil will be enabled to bring the pencil point forward to a writing position without removing the pencil point protector from the pencil body, and with which also the pencil point may be as readily returned to its protected position and this also without removing the pencil point protector from the pencil body.

In carrying out my present invention, which relates specifically to one of the forms of pencil point protector shown and described in my co-pending application, Serial No. 336,735, filed September 29, 1906, I employ a pencil point comprising a main or body portion adapted to lit over a lead pencil, a reduced portion at one end of the said main or body portion and slotted to provide ii -turned or depressed longitudinally disposed tongues adapted to frictionally engage the said surface of a lead pencil to normally maintain the protector in the desired position thereon, and preferably a reduced or crimped portion at the opposite end of the main or body portion and adapted to yieldingly engage the pointed end of the lead pencil when in use and to limit the longitudinal movement thereof within the protector so as to determine the extent to which the pointed end of the pencil may be protruded beyond the said body portion of the protector as will be hereinafter more particularly described.

In the drawing, Figure 1 is a side elevation of my improved pencil protector, and Fig. 2 is a longitudinal section on line 2, z, of the pencil point protector disclosed in Fig. 1.

Referring to the drawing, a designates the main or body portion which is preferably cylindrical in cross section and whose inner diameter is such as to permit this body portion a to be passed freely over an ordinary lead pencil b whether the same is circular, hexagonal, octagonal or of any other cross section. Furthermore, this main or body portion a may be made of any suit able material and the surface thereof may be corrugated, serrated or roughened in any suitable manner, or covered with any desired material such for example as paper, rubber, celluloid or varnish. Furthermore, it may be noted here in connection with the description of this main or body portion a, that inasmuch as the interior diameter of the same is appreciably greater than the exterior diameter of an ordinary lead pencil b, the exterior diameter of the portion a will be appreciably greater than that of the lead pencil 1), thereby forming an agreeable grip for the Writer in the use of the lead pencil.

At one end of the main or body portion a I employ a reduced end portion 0 provided with slots 6, thereby making provision for the oppositely placed longitudinally disposed inturned or depressed tongues 7, which are adapted to frictionally engage the surface of the lead pencil to maintain the protector in the desired position thereon and at the opposite end of the main body portion a, I employ a reduced conical portion (2 provided with one or more longitudinally disposed slots e, the said conical portion d being adapted to yieldingly engage the pointed end of the lead pencil when in use and to limit the movement of the'same in one direction within the protector.

I claim as my invention:

1. A pencil point protector comprising a main part of relatively greater interior diameter than the diameter of a lead pencil, a part of reduced cross section at one end of the said main part and having slots providing for longitudinally and oppositely disposed tongues adapted to frictionally engage the surface of the lead pencil and means at the other end of the said main part for yieldingly engaging the sharpened end of the lead pencil when the same is in use and limiting the movement of the pencil Within the protector.

2. A pencil point protector comprising a main part of relatively greater interior diameter than the diameter of a lead pencil, a part of reduced cross section at one end of the said main part and having slots providing for longi tuclinally and oppositely disposed tongues in alinement on diametrically opposite sides of the said part of reduced cross section, which tongues are adapted to frictionally engage the surface of the dead pencil and means at the other end of the said main part for yieldingly engaging the pointed end of the lead pencil when the same is in use and for limiting the movement of the pencil in one direction Within the protector.

3. A pencil point protector comprising a main part of relatively greater interior diameter than the diameter 'of a lead pencil, a part of reduced cross section at one end of the said main part and having slots providing for longitudinally and oppositely disposed tongues in alinement 0n diametrically opposite sides of the said part of reduced cross section, which tongues are adapted to frictionally engage the surface of the lead pencil and a conical part integral with the other end of the said main part and pro; vided with a longitudinally disposed slot whereby the said conical part is adapted to frictionally engage the pointed end or the lead pencil when in use, to limit the movement of the lead pencil in one direction, Within the protector and fix the relation of the pencil and protector for Writing.

Signed by me this 3d day of October 1906.

- OSCAR MUSSINAN.
