CLARENCE WALLACE TAYLOR, OF J ANESVILLE, \VISCONSIN.

FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent No. 320,509, dated June 23, 1885.

Application filed November 14, 1884. (X0 model.)

.To ail whom it may concern.-

Be it known that I, CLARENCE W. TAYLOR, of J anesville, in the county of Rock and State of Wisconsin, have invented certain new and useful Improvements in Fountain-Pens; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in fountain-pens.

Hitherto the construction of the so-called fountain-pens has been such as to require the use of thin wateryink, as the inks in common use have more or less sediment and, after a time, become thickened, and render the use of hair-like tubes for fissures inefficient and unsatisfactory. Again, it has been necessary to use pens of a special construction, which may not be suited to the writers particular needs. The supply and flow of the ink has also been unsatisfactory under various circumstances, and the popularity which attended their introduction has gradually diminished as their defects have become apparent.

The object of my present invention is to provide a simple, cheap, and durable fountainpen, which can be adjusted to operate well when held at any required angle in the hand of the writer, with any ordinary ink, and with either a steel or gold pen of ordinary construction, a further object being to provide a reservoir adapted to supply the pen with ink without the use of valves or other movable machinery, thereby avoiding the liability to clog by the thickening of the ink and sediment.

With these ends in view my invention consists in certain features of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a longitudinal sectional view of the pen and holder. Fig. 2 is an enlarged longitudinal section of the lower portion of the same. Fig. 3 is a transverse section through the line at y of Fig. 1. Fig. 4 is. a detached View of the adjustable bar, and Fig. 5 is a sectional view of the cap.

A represents the barrel of the pen-holder,

provided with the reservoir (1, adapted to receive ink of any ordinary make. The pointsection Bis fitted with a thread, Z), on its upper end, adapted to engage a female thread, I), in the lower end of the barrel A, by means of which the section B may be removed and adjusted, and the reservoir a be filled, cleaned, &c.

The section 'B is provided with a channel, 0, communicating freely with the reservoir a and with an ink well or receptacle, 0, located at the lower end of B, by a small perforation or capillary tube, 0'.

D is the pen. 'It is secured to the section B by inserting its upper end in a suitable socket, d, and its lower or slitted portion, a short distance above the point, covers the well 0. A slight space is left between the pen and point-section, above the well, to prevent the ink from creeping up.

The section B is further provided with a longitudinal opening, E, extending from the reservoir a to the well 0, in which an adjustable stop, F, is located. The stop F consists of a bar smaller in cross-section than the opening E, and provided with bulkheads ff at the lower and upper ends, respectively, adapted to closely fit and slide within the opening E, forming air-tight joints. The heads f and f are provided with small perforations e e, communicating with the open space E and the well 0 and reservoir a.

A perforation, G, is formed in the upper portion of the section B, extending from the outside air to the upper portion of a longitudinal channel, formed in the back of the piece F, the said channel communicating with the well 0 through a perforation, fi, formed in the lower end of F.

A cap, H, provided with an internal lug or projection, h, is constructed to fit over the pen and lower section of the holder, the face of the projection 71, when the cap is in position, being over the hole or slit in the pen, and the upper portion of the cap tightly closing the perforation G, thereby shutting out the air from contact with the ink in the well 0, and preventing evaporation.

The operation of the pen is as follows: As the pen is pressed upon the paper it recedes slight-1y from the well 0, and the ink therein flows downwardly toward its point ready for use. When the supply in the well 0 falls below the perforation e in the headf, air enters through the perforation G, channel 9, and perforation 9 into the well a, and from thence passes upwardly through the perforations .e and 6 into the reservoir a, and displaces a sufficient amount of ink to fill the well 0, the ink passing into the well through the perforation or tube 0. As the ink enters the well a it closes the perforation e, and thereby stops a further displacement in the reservoir a until the ink in the well a is again used below the said perforation e.

The air in the opening E holds the ink in the reservoir and well in equilibrium so long as the perforations e and e are closed thereby, and only enters through the perforation 6 into the reservoir a when atmosphericpressure is exerted through the perforation G, &c., as be fore explained.

The piece F is adapted to slide longitudinally in the opening E, and thereby determine the point at which the ink in the well 0 shall fall below the opening 0. Thus the pen may be held at different angles with the paper without changing the point at which the displacement in the reservoir takes place by simply adjusting the piece F up or down, as may be necessary.

By the above construction the ink may be used to the last drop, the flow will be automatic and constant, and as there are no valves or movable parts to become clogged the pen Will retain its usefulness and remain in Work ing order until the ink-reservoir is empty.

It is evident that slight changes may be made in the form and arrangements of the several parts described without departing from the spirit and scope of my invention; hence I do not wish to limit myself strictly to the construction herein set forth; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with a pen-holder and a pen, of an ink-reservoir located within the holder, an ink well or receptacle adapted to directly feed the pen, said well being connected with the reservoir by a capillary tube for the passage of ink and by an air-chamber for the passage of air, substantially as set forth.

2. In a fountailrpen, the combination, with an ink well or receptacle adapted to directly feed the pen and an ink-reservoir connected with the well by a capillary tube, of an airchamber located between the well and reservoir and an adjustable perforated stop adapted to fit within the air-chamber, substantially as set forth.

3. The combination, with the pen-holder and a pen, of an ink-reservoir located in the handle, an ink-well located immediately beneath the pen, said well being connected with the outside air by a permanent opening and with the reservoir by a capillary tube for the passage of ink,and by an air-chamber for the passage of air, substantially as set fort-h.

4. The combination, with an ink-well located immediately beneath the pen, and an inkreservoir adapted to furnish ink to the said well, of an adjustable double stop adapted to fit and slide within an opening between the well and the reservoir and admit air to the reservoir at points suited to different angles of the holder, substantially as set forth.

5. The combination, with an ink-well and an ink-reservoir connected therewith by a capillary tube, of an adjustable stop locatedin an opening between the well and the reservoir, provided with an air channel adapted to transmit air from a perforation in the holder to the well and from the well to the reservoir, v

substantially as set forth.

6. The combination, with a pen-holder hav-' ing an ink-well located immediately below the slit or hole in the pen, and provided with an ink-opening communicating with a passage from the ink-reservoir and an outside airopening, of a cap adapted to completely cover the pen and close said outside air-opening, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscrib- 1 ing witnesses.
