FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent N 0. 599,691, dated March 1, 1898.

A ar -mot filed m 26, 1897. fierial No. eiaooo. (No model.)

, To an whom it may concern:

Be it known that I, HUGH II. DE FRANCE, a citizen of the United States, residing at Golden, in the county of Jefferson and State of Colorado, have invented certain new and useful Improvements in Fountain-Pens; and

' I do hereby declare the, following to be a full,

fountain-pens, and particularly to that class thereof in which the ink-chamber of the pen is filled with ink by the actionof a piston working in the ink-chamber; and it consists in an improved fountain-pen of this character provided with an attachment for'regulating the flow of ink to the pen the construction and arrangement of the parts of which will be hereinafter fully described, and particularly pointed out in the claims.

The object of my invention is to provide fountain-pens in which the ink-chamber is filled with ink by the action of a piston workthe case of the pen.

ing within the same, with an attachment for regulating the flow of ink to the pen, which will be simple in constructiomeasy to manipulate, and not liable to get out of order.

In accomplishing the object of my invention I attach to the piston which works within the ink-chamber a piston-rod which is sufficiently long to extend outside of the case in which the ink-chamber is held at all times during the movement of the piston. Near the outer end of the piston-rodI attach a feedrod, which slides in a slot or groove formed in the pen-case. long to allow for the outward movement of the piston-rod Without leaving the groove in which it is held. The groove in which it slides is formed on the thumb-hand side of the case, and the feed-rod is provided with a thumb-piece by means of which it can be operated so as to force the piston inward and cause the feeding of ink to the pen. The thumb-piece is preferably pivotally attached to the feed-rod, so that it will turn down upon When in this position,

it serves as a clamp toprevent movement of the feed-rod, and therefore of the piston, so that-improper feeding of ink to the pen is avoided.

The feed-rod is sufficiently My invention is fully illustrated in the drawings which accompany and form a part of this specification, in which the same reference-letters refer to the same or corresponding parts, and in Which Figure l is a sectional view of my improved fountain-pen. Fig. 2 is a detail view showing the piston, piston-rod, and feed-rod. Fig. 3 is a detail view showing the pen-case and the groove cut therein, within which the feedrod'slides. Fig. 4 is a view of some of the forms of ink-chambers which can be used in connection with my pen.

Referring to the drawings, Arepresents the ink-chamber ofi my fountain-pen, and B the case thereof. The feed end of the ink-chamher is somewhat conical in shape, as shown at a, and is formed with an opening at its apex a, through which ink flows upon the point of the pen 0. The pen 0 is inserted in a groove 1), formed in the end of the case of the pen, and may be either gold or steel. Any ordinary form of pen may be used. By changing the form of the end of the ink-chamber according to one of the types shown in Fig. at the pen can be either inclined to or lie in the plane of the case.

Within the ink-chamber is the piston D. The piston D reciprocates within the inkchamber and serves when drawn backward to draw up ink within the ink-chamber in the customary and well-known manner. To it is attached the piston-rod D, formed with a head or end D by means of which it can be conveniently operated.

To the outer end of the piston-rod D is attached one end of the feed-rod E, which slides in the groove E, formed on the thumb side of the pen-case, and has attached thereto a thumb-piece E, by means of which it can be convenientlyoperated. Thethumb-pieceE when the pen is being used, is at right an gles to the body of the pen. It maybe formed integrally with the feed-rod or may be pivotally attached thereto. The latter construction is preferable, for it enables the thumbpiece to act as a clamp when bent down so as to lie flat with the pen-case, and thus prevent accidental movement of the feed-rod and piston. It is this construction that is shown in the drawings. In the pen-case there is formed the aperture E in which the thumb= piece may be clasped down when the pen is not in use. Aband E passes around the pencase, near the rear end thereof, and serves not only to hold the feed-rod within the groove provided therefor, but to prevent the piston from being drawn out of the tube.

The operation of my pen is very simple. By unclasping the thumb-piece E immersing the point of the pen and tube in the ink, and drawing the piston outward the tube or ink-chamber is filled with ink and is ready to write three or four pages. After that a slight drawing of the piston inward, which is done by placing the thumb on the thumbpiece and pressing the same a short distance toward the pen-point, renews the flow of ink to the pen and three or four more pages can be written, and so on till the reservoir is emptied.

The reservoir and pen can be thoroughly cleaned by immersing it in water and operating it like a syringe.

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

1. In a fountain-pen, the combination with a pen-case, an ink-reservoir, a piston and a piston-rod attached thereto, of a feed-rod attached to said piston-rod and extending down the side of the pen-case, and means for holding said feed-rod in a fixed position, whereby accidental discharge of ink is prevented, substantially as described.

2. In a fountain-pen, the combination with a pen-case having a groove cut therein on the thumb side thereof, an ink-chamber, a piston and a piston-rod attached thereto, of a feedrod attached to said piston-rod and guided within the groove in said pen-case, and a thumb-piece pivotally attached to the inner end of said feed-rod whereby when said thumb-piece is turned down, it will clamp against the ink-reservoir and hold said feedrod in a fixed position, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

HUGH II. DE FRANCE.
