JOHN HOLLAND, OF CINCINNATI, OHIO.

FOUNTAIN-PEN,

SPECIFICATION forming part of Letters Patent No. 300,260, dated June 10, 1884-,

Application filed April 4, 18834 To (LZZ 1071 0717 it may concern:

Be it known that I, J OHN HOLLAND, a citizen of the United States, residing at Cincinnati, county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Fountain-Pens, of which the follow ing is a specification.

My invention relates, particularly, to that class of fountain-pens in which the common writing-pen is continuously supplied with ink when in use from a reservoir which is also the pen-holder. Its object is to simultaneously open the air vent and communication between the pen and inkreservoir to supply the pen withink when in use, and to simultaneously close the air-vent and out off communication with the reservoir, so as to prevent leakage when the pen is carried in the pocket, and at the same time to insure a regular flow of ink to the pen, and prevent leakage at the top or vent-cap.

With these objects in view my invention consists in certain details of construction and combination of parts, as will be hereinafter described, and pointed out in the claim.

The accompanying drawing is a central longitudinal sectional view of a fountain-pen provided with my improvements.

The reservoir-holder A, pointsection 13, upper plug, 0, with the tube D attached to it and extending into the reservoir, vent-cap E,and pen F, are of ordinary construction and well known to the trade; but in the pens now in use, whether of the characterhere shown or those which are known as stylographic fountain-pens, tlie'tnbe 1) serves to conduct air to the point-section to insure a how of ink to the writing-point, while in my pen it is only used to prevent leakage at the cap In my pen the air is supplied to the lower end olthe (No model.)

point section by the tubular rod G, which snugly fits-within the 'tube D. The ends of the tubular rod G are closed. The lower end is provided with a conical-shaped valve, 9, and the upper end is attached to the vent-cap E. Beneath the vent-cap the rod G is transversely perforated at h, and justabove the valve are similar transverse perforations,i, so that when the vent-cap is raised air is admitted through the perforations h z to the ink in the lower end of the point-section, and the valve 9 is simultaneously lifted from its seat, to permit a free flow of ink from the reservoir to the pen F through the lower curved end of the point-section. c

I am aware that it is old in fountainpens to secure the combined valve-rod and air-tube to the air-cap or other device at the top of the reservoir-holder, so that the valve may be raised from or lowered to its seat in the pointsection; but I am not aware that a combined valve-rod and air-tube secured to the ventcap has ever before the date of my invention been used in combination with a reservoirholder having at its upper end a fixed plug provided with adownwardlyextending tube, which acts as a support and'guide for the combined air-tube and valve-rod.

hat I claim as new, and desire to secure by Letters Patent, is-

Ilie combination, substantially as specified, of the holder A, point-section B, plug G,tube D, cap E, and pen F with rod G, secured to the cap E, and having valve g and vents 71 i, for the purpose set forth.

JOHN HOLLAND,
