STYLOGRAPHIC FOU NTAlN-PEN.

SPECIFICATION forming part of Letters ,Paten-t No. 236,877, dated January l2.5, 18, 81.

Application filed November 15, 181:30. (No model.)

To all whom it may concern Be it known that I, CHARLES H. DowNEs, of Jersey City, in the county of Hudson and State ot' New Jersey, have invented certain new and useful Improvements in Stylographic Fountain-Pens and Fountain-Pen Holders, of which the following is a specification.

My invention relates to improvements in writing-instruments of the fountain kind; and it is applicable to stylographic fountain-pens and to fountain-holders which are adapted for receiving the ordinarr Writing-pens.

My invention consists, mainly, in a handle for a Writing-instrument which is formed of two tubular ink-receptacles, one within the other, the inner receptacle bein g provided with apertures for receiving external air, and also with an aperture for allowing ink from the outer receptacle to iiow into said inner receptacle and out ot' the same, for supplying the writing-point with ink, as will be hereinafter explained.

The invention also consists in novel means for adjusting the tension of the needle-spring, and also for adjusting the needle to the Writing-point of the point-section, as will be hereinafter explained. I attain these objects by means shown in the annexed drawings, in which- Figure 1 is a diametrical section through the improved pen-holder, having a stylographic writing-point on one end and a sheath on the other end, with an ink-delivery point for an ordinary writing-pen. Fig. 2 is a sectional view of the inner ink-tube havin g the improved needle and spring adjusting devices applied to it. Fig. 3 is a diametrical section, showing a modification of the pen adapted for a stylo- Fig. 4 is another modification,

barrel and a very small air-tube at the upper end of the inner ink-tube.

Similar letters refer to similar parts throughout the several views.

In the annexed drawings, A designates the barrel or outer tube of my improved pen-handle, and B isa small tube which is applied centrally inside of the barrel A. This small tube B is perforated near its extremities, at a a, for establishing a communication between its interior and the space @between it and the outer tube or barrel A. These apertures @a allow ink to flow from the reservoir e into the tube B.

I now refer to Fig. 3, which shows a stylographic writing-point, C, applied to the handle. The linner tube, B, in this Fig. 3 passes airtight through a section, D, and has the writing-point VG secured to its exposed end. The upper end of tube B is fixed to a plug, E, in the end of the barrel A, on which plug is screwed a cap, F. By slightly unscrewing cap F air is admitted through aperture c into the small ink-tube B; but when the cap F is screwed home no air will be admitted through aperture c. A perforated septum, d, is shown applied in the ink-space e, between the two barrels A B, lwhich will, in a measure, support the column of ink above it when the handle is full of ink. The ink which is received into the receptacle formed by the bore of tube B flows therefrom, during the act of writing, through the writing-point C, provided air is admitted through the aperture c. This writing-point C of Fig. 3 should be provided with a needle, which may be made adjustable, as will be hereinafter explained.

Fig. 4 shows the inner tube, B, terminated in a point, d', adapted for supplying ink to a common pen, G, iitted in a sheath, H. The tube B in this figure (4) receives air from a smaller tube, B', supplied through an inletaperture, c, when cap F is slightly unscrewed.

Instead of the pen-sheath H and the delivery-point d', a stylographic writing-point, C, like that shown in Fig. 3 may be substituted.

Fig. l shows my improved fountain-handle, having on one end a stylographic writingpoint or point-section, and on the other end a pen-sheath, H, like the sheath shown in Fig. 4. Instead of this sheath H, a stylographic point-section may be substituted, which will afford a finer or a coarser line than the writing-point on the opposite end of the handle. The air is admitted into the inner ink-tube, B, of the handle of Fig. 1 through a short tube, f, which may be located at any desired point between the ends of the handle. The inner ink-tube, B, of Fig. l passes through a packing, h, and terminates inside of the point-section C, and is provided with apertures b b, for the escape of ink into this point-section.

IOO

riruma I It will be seen from the above description that I dispense with the air-tube commonly used in stylographic fountain-pens, and utilize nearly the entire space within the barrel A as a reservoir for ink. I have a large external ink reservoir or feeder, e, and a smaller inkreceiver, B, from which latter the ink Hows to the Writing-point.

Fig. 2 shows my improved needle attachment, which may be applied on the lower end of the ink-tube B, as shown in this figure; or it may be applied inside of tube B of Fig. 3, or it may be attached to the point-section of Fig. 1. The needle bz is loosely applied to a tube or holder, c2, and provided with a head, p. The tube c2 is screw-threaded, and is tapped into the lower end of a tube, d2, so that it is adjustable endwise therein. A screw-threaded pin, e2, is tapped through a septum, g, and is adjustable over the head of the needle b2, for regulating the amount of vertical play thereof. A spring, f2, by its recoil on the needlehead, acts to keep the needle down on its seat. The tension of this spring is regulated by adjusting the tube c2 in the tube d2, and the amount of protrusion of the point of the needle beyond the writing-point is regulated by adjusting the tube d2 up or down on the inktube B.

1f it is desired to apply the needle attachment inside of the tube B of Fig. 3, or inside of the point-section C of Fig. 1, the external surface of the tube d2 may be screw-threaded, and grooves formed lengthwise in it to allow the passage of ink to the writing-point.

1t will be seen that the lower extremity of the ink-reservoir e is tightly closed, thus causing the ink contained init to pass through the lower perforation, a, into the ink-tube B before escaping from the writing-point.

The letter h iu Figs. 3 and 4designates a tight contraction about the ink-tube B, which is the equivalent of the packing h in Fig. 1, for closing the lower end of the ink-rescrvoire.

What 1 claim as my invention is 1. A fountain pen holder formed of two tubes, A and B, having the chamber e closed at h, and the ink tube B perforated at a a, substantially as described.

2. A writing-instrument in combination with the packing h, the perforated ink-tube B, and the external ink-chamber formed by the outer tube or case, A, substantially as described.

3. For a fountain-pen, a needle, b2, loosely attached to a tube or holder, c, in combina tion with the tube d2, its adjusting-pin e2, and tension-spring f 2, substantially as described.
