FLUID-HOLDING PENCIL.

SPECIFICATION forming part of Letters Patent No. 501,958, dated July 25, 1893.

Application filed February 13, 1893. Serial No. 462,152. (No model.)

To all whom it may concern;

Be it known that we, WALTER B. OLMSTED, HERBERT O. WARNER, and HOWARD A. GID- DINGS, of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Fluid- Holding Pencils, of which the following is a full, clear, and exact description, whereby any one skilled in the art can make and use the same.

This invention appertains to fluid holding pencils, and especially relates to ink-erasers.

The object of this invention is to provide a fluid holding pencil or ink-eraser which shall be simple and cheap in construction and may be quickly and easily filled.

With this object in view theinvention consists essentially in a fluid holding pencil, comprising a tubular portion to contain the fluid having a conical or tapered lower end with a small puncture or outlet therein, a flanged upper end having a small inlet opening, and means for hermetically closing said inlet; and it also consists in the particular construction and in the combination and arrangement of the parts substantially as hereinafter more particularly described and as set forth in the claims.

Referring to the drawings: Figure l represents in central longitudinal section a fluid holding pencil constructed substantially in accordance with this invention. Figs. 2, 3 and 4 are sectional details showing modified forms of tops and closures. Fig. 5 isa detail of the stopper showing cement coating.

In the drawings the letter a represents the fluid holding pencil which will preferably be formed of glass having the tubular body I) to contain the fluid tapered at its lower end as at c with a longitudinal puncture d therein. The upper end a of the tubeb will preferably have an internal flange'fremote from the upper end with an inlet openingg therethrough as shown in Fig. 1, in which figure the pencil is shown as straight from the extreme upper end to the .base of the conical pointed end 0. This particularconstruction is preferable but it will be obvious that the upper end of the pencil might be formed as illustrated in Figs. 2, 3 and A.

The pencil is charged with fluid through the inlet 9 in the upper end 6, which end is hermetically sealed, preferably by a stopple h subjected to a coating of hot glue or cement 2' see Fig. 5, which stopple is inserted into the neck of the pencil while the glue or cement is in a molten or heated condition the setting of the glue or cement insuring an air tight joint. After filling the pencil and inserting the stopple the mouth of the pencil above the stopple may be filled with cement or wax, as shown at 2', Figs. 1, 2 and 3.

The filling and sealing of the pencil together with simplicity and cheapness in cost of manufacture are the chief objects of this present invention, and its advantages will be readily apparent to any one skilled in the art to which it appertains. By this construction and arrangement the pencil may be inverted in the pocket Without liability of leakage. It is obvious that the subsequent filling of mouth of the pencil above the stopple, after the same is in place might be dispensed with without departing from the spirit of our invention.

I We claim as our invention- 1. As an improved article of manufacture, a tubular fluid containing pencil having a punctured and tapered lower end, and an internally flanged upper end with an inlet opening therethrough, in combination with a stopple to hermetically seal said inlet, substantially as described.

2. An ink-eraserpencil consisting of a tubular body containing a fluid, and having a tapered punctured marking end and an internally flanged upper end with an inlet opening therethrough, a stopple inserted in the upper end of said pencil with glue or cement interposed between the stopple and neck of the pencil to hermetically seal the same, substantially as described. 7

3. The pencil having the tubular body I) filled with fluid, and having the tapered end 0 with the puncture dtherethrough, the flange fnear the upper end of the tube having the inlet opening 9 therethrough, in combination with the stopple h having the cement or glue 1', and the supplemental coating 2" to cover the face of the stopple, substantially as and for the purpose described.

4. As an improved article of manufacture a tubular fluid containing pencil having a cased in a coating of hardened adhesive ma- IO punctured and tapered lower end and with an terial, all substantially as described.
