INK RESERVOIR FOR LETTERING PENS Filed Aug. 16, 1949 .2 5" W /Z X I a 7 I a /7 I L h at /6 A? /Zl INVENTOR Patented Feb. 26, 1952 UNITED STATES PATENT OFFICE (Granted under the act of March 3, 1883, as amended April 30, 1928; 370 0. G. 757) 3 Claims.

The invention described herein may be manufactored and used by or for the Government of the United States for governmental purposes Without payment to me of any royalty thereon in accordance with the provisions of the act of April 30, 1928 (ch. 460, 45 Stat. L. 467).

This invention relates to an ink reservoir for pens, and particularly to one adapted for mounting in a common form of penholder and over which is fitted a pen of suitable contour or conventional type pen and holding spring clip.

In the accompanying drawings:

Figure 1 is a plan view of the device;

Figure 2 is a longitudinal section;

Figure 3 is a view of the device looking from the right of Figure 1;

Figure 4 is a longitudinal section of a conventional pen and an attaching spring clip; and

Figure 5 is a section on the line 55 of Figure 4. 1 a

In these drawings, a common form of penholder ill, frictionally holds an attaching part II of a reservoir I2 within which is mounted a reciprocative rod 13 having a handle l4 and a tapered point IS. The rod [3 is guided by a sleeve l8 and is adapted to enter and to be extended through a discharge hole I! in the reservoir 12. A pen of suitable contour or conventional type pen I 8 frictionally and resiliently grips the reservoir I2 and receives along its under-side a supply of India ink which flows through the hole I1. The rod I3 serves to normally close the hole I! and is raised to permit ink to flow to the pen I8 which has, initially, been inked by use of the quill of the ink-bottle stopper. Whenever drying ink tends to clog the hole I! the clotted ink may be extruded with the aid of the rod l3 without removing the pen I8 or touching any inked portion of my device. Figures 4 and 5 illustrate a pen securing clip [9 which serves to clamp a pen against the reservoir.

In use a draftsman needs a single one of my reservoirs, a common penholder and a supply of pens of varying degrees of fineness. Because the pen is the part which requires most frequent renewal and is a commercially available article of commerce, my combined device enables a draftsmanto reduce to a minimum the number of reserwits and penholders which he may need to meet the varying requirements when lettering and making free hand inked drawings.

It'should be understood that the present disclosure is'for the purpose of illustration only, and that the invention includes all modifications and equivalents which fall within the scope of the appended claims.

What is claimed is:

1. A device of the class described which includes an ink reservoir provided with a cylindrical wall and a closure adjacent to a pen point and open approximately at the rear end of a pen which closure is provided with a discharge aperture, an internal guiding sleeve underlying said pen and terminating adjacent to the rear end of the pen and rigidly secured within said reservoir with its axis parallel to the elements of said cylindrical wall portion and in alignment with said discharge aperture, a reciprocative tapered regulating rod provided with a handle mounted in said sleeve for manually regulating the gravity feed of ink through said aperture, a resilient clip straddling said cylindrical wall for detachably clamping an ordinary pen between said clip and said cylindrical reservoir wall, and a penholder attaching extension rigidly united with said reservo1r.

2. An ink reservoir for use with a common type of pen and a common type of penholder which comprises a reservoir having a pen supporting cylindrical wall which fits the inner side of a pen and is open approximately at the rear end of a pen and is provided with a rod guiding sleeve adjacent to the supporting wall and terminating adjacent to the rear end of the pen and a reservoir closure adjacent to a pen point provided with a discharge aperture in alignment with said sleeve, a reciprocative rod provided with a handle and a tapered point mounted in said sleeve said handle positioned adjacent to the rear end of a pen for regulating the feeding of ink from said reservoir, and a resilient clip straddling the cylindrical reservoir wall for clamping a pen against said supporting yvall in operative combination with said reservoir.

3. In a lettering pen, the improvement which comprises a cylindrical ink reservoir terminating in an ink feeding aperture and extending approximately to the rear end of a pen mounted thereon, a guiding sleeve rigidly mounted within said reservoir in line with said aperture and parallel with elements of an overlying pen and terminating adjacent to the rear end of the pen and a resilient clip straddling a cylindrical wall of said reservoir for clamping a pen thereto and a terminally tapered rod provided with a handle mounted within said sleeve and adapted to be reciprocated into and out 'of said aperture, said handle being operated by movements of the forefinger of a hand holding the device.
