2 Claims.

This invention relates to slide cartridges for pencils or other supports, and has for an object to provide an improved construction wherein a flexible rubber eraser, lip stick, or other article 5 may be carried by the end of a pencil or similar shaped support and be protected both when in use and when not in use.

Another object is to provide a pencil or other cylindrical support with an extension at one end formed of flexible rubber, lip stick, or other substance, together with means for holding the eraser or other article in place and a tubular protecting member telescopically fitting over the pencil, support and rubber eraser.

A further object of the invention is to provide for pencils and the like, an elongated elastic rubber eraser at one end, with a protecting sleeve open at both ends telescopically mounted in position so that from time to time it may be telescoped over the pencil and thereby expose more and more of the free end of the eraser.

In the accompanying drawing-- Figure 1 is a side view of an embodiment of the invention shown applied to a pencil;

Fig. 2 is an enlarged view partly broken away for showing certain detail structure not illustrated in Fig. 1.

As shown in the accompanying drawing, the invention has been applied to a pencil either 3 round or hexagonal. However, it will be understood that the invention could be applied to cylindrical objects not formed as pencils.

In the drawing, l indicates a hexagonal pencil which is provided with a metallic holder 2 having portions crimped or pressed inwardly to the pencil body and certain parts 3 pushed appreciably into the wood of the pencil l for firmly holding or looking the holder 2 in place. The holder projects past the pencil body I and forms a tubular socket for the article 4. The article 4 is shown as a round flexible rubber eraser, but a lip stick or other article could be substituted without departing from the spirit of the invention. Normally the cap 6 is arranged in position as 4 shown in the drawing to protect the upper or free end of the eraser, but thiscap is removed when the eraser is to be used. The same is true if a lip stick is substituted for the eraser. It will therefore be understood that where the expression eraser. or fiexible rubber eraser is used, the term includes a lip stick or other desirable article which may be substituted for the eraser. A cover or sleeve 1 telescopically fits over the eraser 4, holder 2, and part of the pencil body I.

5 Normally the parts are arranged as shown in the drawing when the parts are new.

The knurled portion 9 on sleeve 1 acts as a desired finger hold and also with beads l and I I to sufficiently stiffen or reinforce the slide. The bead l0 also acts as abutment or stop for the cap 6 which cap is also provided with a reinforcing bead 12. The sleeve! is formed with one or more pressed-out burrs or portions It at the top so as to frictionally hold the cap 6 in' place. At the bottom one or more burrs M are pressed out which frictionally engage sleeve I for preventing any accidental movement thereof. The burrs l4 are pressed from the holder 2 while spurs l3 are pressed from sleeve 1. As the eraser is used in this form of the invention the sleeve 1 may be moved downwardly from time to time until the shoulder l5 strikes the upper end of holder 2. If it is desired to use as much as possible of the eraser, sleeve 1 iscompletely removed from the pencil, preferably by a pull in a direction away from the point. It will be understood that the holder 2, sleeve 1 and cap 6 may be made from metal, rubber, Bakelite, wood, Celluloid, or other material.

While a certain form of holder 2 has been shown, it will be understood that other forms may be used without departing from the invention, the essential feature being to secure an eraser to the body I while permitting the sleeve '1 to readily telescope thereover. The sleeve 1 is held in place as is also the cap 6.

I claim: I l. A slide cartridge for pencils comprising metal holder secured to the pencil for holding an article at one end of said pencil, said holder being formed with pressed-in parts extending into said article for holding the article against removal pressed-in parts extending into said pencil for securing the holder to the pencil and pressedout spurs at one end, and a tubular cover telescopically fittingover said article and frictionally engaging said spurs, said holder and part of said pencil, said cover being adapted to be slid longitudinally over more and more of said pencil as more and more of said article at its free end is worn away, said spurs acting to prevent accidental movement of the cover in respect tothe holder.

2. In an eraser mounting, a tubular metal holder formed with means adapted to interlock with one end of an eraser, said holder having an outwardly extending spur and a cover slidingly mounted over said eraser and said holder positioned to frictionally engage said spur whereby the cover may be held in different adjusted positions, said cover at its outer end being constricted to fit said eraser for preventing undue bending thereof, said constricted portion having an outwardly extending cap-receiving spur.
