CHARLES R. KEERAN, F CHICAGO, ILLINOIS, ASSIGNOR TO REALITE PENCIL MANU- FACTURING COMPANY, OF CHICAGO7 ILLINOIS, A CORPORATION OF ILLINOIS.

COMBINED ERASER AND LEAD HOLDER.

Application filed August 29, 1921.

To all whom it may concern.'

, hence convenient to carry, and also inexpensive to produce.

Embodiments of my invention in certain preferred forms are herewith shown in the accompanying drawing in the manner following:

Figure l is a perspective view of one holder;

Fig. 2 is a longitudinal section therethrough;

Fig. 3 is a side elevation of a modified construction, the walls being broken away in part to exhibit the interior thereof;

Fig. 4 illustrates in longitudinal section a still further modification, and

Fig. 5 is a fragmentary view in section of one further modification.

The present holder is shown to be in the form of a tube A, made in any appropriate manner, as by drawing, bending, spiral winding or otherwise. The diameter of this tube at each end is such as to frictionally receive an eraser B, commonly made of rubber, the same being compressed slightly when fitted in place.

As shown in Fig. 2, each eraser may be inserted for the greater portion of its length into one tube end. If desired, means may be provided for definitely limiting the entry of the two erasers, consisting of inwardly projecting elements which are preferably in the form of annular beads 5. The two beads are situated from each other a suitable distance which is determined with reference to the length of the leads C, which are to be accommodated within the holder. As shown, a number of such leads may be arranged in place, their ends being preferably rested upon the beads close to the inner ends of the two erasers. It is obvious thatthe erasers provide a closure for each end of the tube, so as to securely retain the leads in place',

and it is further apparent that by the use of stop means to limit the entry distance of the erasers, the latter are prevented from pressing against the leads.

In Fig. 3 is showna modication of the structure just described, but resembling the same in that use is made of a tube A whose two ends are closed by erasers B between which the leads C are retained. It will be noted, however, that the tube in this construction is slightly longer so as to almost completely7 cover the cylindrical walls of the erasers which are located the same distance apart as in Fig. l. To facilitate removalof the erasers, I have shown a slit 6 in the form of an open slot which extends longitudinally from each end of the tube to a point slightly beyond the bead 5. From this it results there is provided through the walls of the tube an opening which lies in part rearwardly of the erasers, thereby permitting a small implement to be inserted behind the erasers to facilitate their ejection from the holder.

Referring now to Fig. 4, I have shown therein a construction which is the same as that disclosed in Fig. l with the exception that no means are provided for limiting the distance of entry of the two erasers; in other words, this construction dispenses with the beads 5. A holder so constructed is used exactly like the others, but the` erasers may be pushed in, if desired, to a point where they will engage the opposite ends of the leads, but no further. This holder construction may be used successfully with leads that do not break easily, but the constructions of Figs. l and 3 are to be preferred where fragile leads, such as indelible, are to be received within the holder.

In Fig. 5 will be noted a further development of the invention herein disclosed. The tube A in this construction is of reduced diameter throughout its central p0rtion 7, a shoulder 8 being formed near each end where the tube diameter is enlarged sufficiently to receive an eraser B. It will be apparent that the shoulder provides a stop for arresting inward movement of the eraser, and that the central portion of the tube is designed to receive a lesser number of leads than in the other constructions heretofore disclosed. Owing to the restricted lead capacity of the holder shown in Fig. 5, wherein the accommodation for is in decided contrast to the containers or cartons which have usually been employed for articles such as leads and erasers, the cost of such containers commonly exceeding the value or" the merchandise which they contain.

I claim l. A holder for leads and erasers comprising a tube whose length exceeds that of the leads therewithin, and means tor closing each end of the tube consisting of an eraser frictionally fitted therein and adapted to lie close to the proximate end of the leads, substantially as directed.

2. A holder for leads and erasers cornprising a tube within which leads may be accommodated in their entirety and in which an eraser may be partly received at each end, and means within the tube for determining the distance to which each eraser may enter therein, substantially as described.

3. A holder for leads and erasers comprising a tube having an inwardly formed bead remote from each end, the tube being adapted to contain a plurality of leads whose length is substantially equal to the distance between the two beads, and an eraser tted into each end of the tube, andv abutting the proximate bead to thereby protect the leads against pressure therefrom, substantially as described.

il. A holder of the kind described comprising a cylindrical tube whose ends are open, a compressible eraser fitted tightly into each tube end and disposed in part eXteriorly thereof, and a plurality of leads carried in the tube between the two erasers, substantially as described.

5. A holder of the kind described coniprising a tube having a slit therein extending longitudinally from one end/thereof, an eraser fitted into the tube end and extending therein Jfor a distance less than the'length 0f the slit, and a plurality of leads contained within the tube and bead and held against removal therefrom at one end by the eraser, substantially as described.
