FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent No. 328,454,dated October 20, 1885.

Application filed August 27, 1885. Serial No. 175,448.

T0 at whom it may concern:

Be it known that 1, JOHN BLAIR, of the city of New York, county and State of New York, have invented a new and Improved Fountain-Pen, of which the following specification is a full, clear, and exact description.

This invention relates to a fountain-pen of simple construction; and it consists in the various elements of improvement hereinafter more fully pointed out.

In the accompanying drawings, Figure 1 is a perspective view of my improved fountainpen; Fig. 2, alongitudinal section of theink' reservoir; Fig. 3, a similar section through the cap; Fig. 4, a similar section through the pen-holding tip. Fig. 5 is a side View of the ink-tube; Fig. 6, a top view of the same, and Fig. 7 a side view of the wood absorbent with in the ink-tube.

The letter a represents a hollow tubular handle or ink reservoir open at one and closed at the other end. Around its open end there is an offset for receiving a cap, I), which is applied when the pen is not used.

c is the pen-receiving tip. This tip is made of a piece of sheet-metal tubing open at both ends,oneend being provided with the customary outwardly projecting spring-jaws, d, between which and the tube the pen is clamped. Vithin the other or rear end of the tip 0 there is introduced a softrubber tube, e, also open at both ends. This tubeis rigidly secured within the tip 0, and partially projects out of the same, as shown in Fig. 4.

f is the ink-tube, curved upward at its front end, so as to be in contact, or nearly so, with the pen. At its rear end the tube f is introduced into the softrubber tube e,which serves to hold it in place. The tu befis provided with two Openings, 9 h, at its upper end, the opening 9 being located near its center to admit air, and the opening it being at the front end to discharge the ink. The opening g is outside of reservoir (1, so that no ink can flow into the same.

Within the tubef there is placed a thin strip (N0 model.)

of wood or other absorbent, t, that operates similar to a wick and serves to convey the ink to the pen. By pushing this strip backward or forward the flow of ink may be increased or diminished.

The soft-rubber tube 6 serves a double purpose-first, it forms a tight joint between the parts a 0 without screw-threading such parts, and, secondly, it permits the ink-tube f to yield so as to conform to the spring of the pen.

I am aware that fountain-pens having an ink-tube with two openings-one of which admits and the other discharges the ink-have been known before my invention, such a pen being shown in Patent N 0. 15,417, granted to A. G. Day, July 29, 1856.

I am also aware that metallic feed pins and springs have been placed into the ink-tubes, as shown in Patents No. 12,301, granted to N. A. Prince, January 23, 1855, and No. 241,215, granted to F. Holland,M-ay 10, 1881, and I do not claim such constructions; but

I do claim as my invention- 1. The combination-of reservoir (4 and tip 0 with the upwardly-curved tube f, provided with the air-opening g and the ink-opening h, the air-opening being located outside of reservoir a, substantially as and for the purpose specified.

2. The combination of reservoir a with the tip 0, containing rearwardly-projecting softrubber tube 0, and with the ink-tube f, fitted into the rubbcrtube, substantially as specified.

3. The combination of reservoir a and tip 0 with the tube f, having openings 9 h, and containing the absorbent strip t, substantially as and for the purpose specified.

4.. The combination of reservoir a with tip c,-having soft-rubber tube 6, and with the curved ink-tubef, having openings 9 h, and strip 2', substantially as specified.

JOHN BLAIR.
