FouNTAlN-PEN.

SPECII'ICATION forining part of Letters Patent No. 349,752, ated September 28, 1886.

Application filed November 2B. 1884. Serial No. 148,982. (No model.) v

To all whom it may concern:

Be it known that I, GEORGE H. SAOKE'r'r, of Brooklyn, in the county of Kings and State of New York, have invented an Improvement in Fountain-Pens, of which the following is a specification. i z

The object of this invention is to provide a fountaiu-pen of cheap and simple construction, easily supplied with ink, not liable to get out of order, capable of cleanly and convenient use, capable of employment with ordinary pens, and readily permitting one pen to b'e replaced by another, when desired. i'

My invention comprises certain novel means whereby said objects are effectually secured.

Figure 1 is a sideview and longitudinal sectional view illustrating my said invention. Fig. 2 is a transverse sectional view taken in the line y y of Fig. 1. Fig. 3 is a side view and partial longitudinal sectional view showing a modification of my said invention. Fig. 4 is a side view of certain parts, of which Fig.V 5 is also a side View, buttaken in a plane at right angles to Fig. 4. Fig. (i is a tranverse sectional view taken in the line u 'w of Figs. 4 and 5.

A is the reservoir or hollow holder of the pen of the usual cyliudrical form, closed at its upper end, open at its lower end, except as hereinafter explained.

B is the plate or diaphragm inserted in the lower end of the reservoir A, and retained in place either by frictionor by any other suitable means. In this diaphragm is an opening, a, through which ink passes to the pen when the latter is in use, and through which air may pass to the reservoir to replace the ink as exhausted therefrom. Vhen desired, one opening, a, may be arranged to feed ink to the pen, and in this opening the pen is inserted and retained, as indicated in the drawings; and another opening provided in said diaphragm to permit the passage of air, as shown at b' in Figs. l and 2.

O is the pen, which is inserted and held in the opening a, formed in the diaphragm B.

vD is a tongue or lip, preferably formed integrally or in one piecewith the diaphragm B, but which, when desired, may be formed separately and affixed thereto by any suitable means. This lip D extends downward substantially parallel with the pen, the lip being either at the outer or inner side of the pen, as preferred. The office of the said lip is to assist in fecding the ink regularly from the reservoir toward the point of the pen, the ink fiowiug through the passage between the pen and the lip.

Eis whatlterm an eXpansion-chamber* 7- that is to say, a Chamber which rcceives any exccss of ink, which, as may sometimes occur, may be forced out through the opening a by an expansion of air above t-he ink within the reservoir from an increased temperature of the air. This expausion-chamber may, however, be dispeused with when desired.

F is a-feedingstem which is extended from the diaphragm upward into the reservoir to facilitate the desceut of the ink Vdownward therein to supply the pen, and also, when the implement is inverted, to facilitate theinward fiow of the ink when the reservoir is filled. This feeding-stem may be made single, as indicated in Figs. 1 and 4, or itv may be made double the whole or any portion of its length, as indicated in Fig. 5, the space between constituting substantially a groovef The most approved construction and arrangement of the parts is that represented in Figs. 8, 4, 5, and 6. In this the diaphragm carries the pen, the lip, and the feeding-stem, and is' capable of easy attachment to and detachment from the reservoir for filling or changing the pen, and is' preferably held in place in the lower or open end of the reservoir by being suugly pressed therein. or, in other words, held by friction. With the construction as represented in said figures the diaphragm is to be inserted in place, as represented in Fig. 3, so that the expansion-chamber E is constituted by the diaphragm as the top thereof, and by the lower portion of the walls of the reservoir as the sides or walls of said chamber.

Having on March 20, 1886, filed Van application for Letters Patent claiming'certainimprovenients in fountain-pens, which said application has since been allowed, Ihereby, for the purposes of this my present application, disclaim all features which are claimed in said application of March 20, 1886.

What I claim herein as my invention is-' 1. The combination, in a fountain-pen, of the tubular reservoir A, tightly closed at its upper end, and the diaphragm provided With the lip and pen, said diaphragm having a passage for ink from the interior to the capillary channel between the lip and pen, andan opening, a, for the admission of air to the lower end of the reservoir, Whereby an air-tube may be dispensed with, substantially as and for the pnrpose herein set forth.

2. The combination, in a fonntain'pen, of a diaphragm construeted with a suitable opening to receive and retain a Writing-pen, and With an air pnssage or opening, a, a lip, D, at-

tached to said diaphragm and arranged to lie substantially parallel to said writing-pen, and

a feeding stem, also attached to said dia- 15 phragm, the whole construeted and arranged for insertion in and removal from the reservoir of a fountan-pen, all substantially as and for the purpose herein set'forth.

GEORGE I-I. SACKETT.
