FOUNTAIN-PEN.

SHEQIFICATIQN formingpart of Letters Patent No. 709,307, dated September 16, 1902.

Application filed June 26. 1902. Serial No. 113,269. (No model.)

. nosha, in the county of Kenosha and State of Wisconsin, have invented certain new and useful Improvements in Fountain-Peus; and

I do declare the following to be a full, clear, and exact description of the invention, such I as will enable others skilled in the art to which p 3, which receives the capillary tube 4, exteit appertains to make and use the same.

This inventionrelates to fountain-pens of the stylographic type,designed as an im prove ment upon the fountain-pen shown and described in my Letters PatentNo. 699,499, dated May 6, 1902, whereby, first, provision is made for varying the density of the hygroscopic or absorbent material to regulate the flow of ink through the pen-point; second, provision is made for removing the capillary tube, whereby the barrel of the pen may be filled by injection in the usual manner, and, third, provision is made for the removal of thetubular pen-point, whereby when it becomes worn or damaged it may be replaced with a new or perfect one.

With these objects in view the invention consistsof certain novel features of construction, combination, and arrangement of parts, which will be hereinafter more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a perspectiveview of the stylographicpen, illustrating the pen-point closed by the usual cap. Fig. 2 is a longitudinal sectional view through the pen, showing the cap slipped over the upper end thereof. Fig. 3 is a view showing in perspective, on an enlarged scale, the several parts constituting the pen; and Fig.

'4 is a fragmentary view of the tip of the pen- In the drawings, 1 denotes the barrel or reservoir of the pen, the upper end of which is formed with a capillary chamber 2, termihating in an interiorly-screw-threaded neck riorly screw-threaded to engage said neck and provided with a head 5, which when the tube is screwed firmly home engages theend of the neck and forms a complete air-tight closure. The opposite end of the barrel is screw-threaded, as at 6, and is formed with atubular extension 7.

8 denotes the tubular pen-point, the lower end of which is conical and is formed on one side with a flat surface 9, which has a feedaperi ure 10, preferably oblongin outline and having its walls leading to or nearly to the extreme tip of the pen-poin The opposite end of the tubular pen-point is provided with an annular shoulder 11. .The pen-point is slipped over the end of the extension 7, and an interiorly-threaded coupling-sleeve 12 is slipped over the pen-point and engages the shoulder 11 and has its threaded portion engaged with the threaded portion Got the barrel., Located within the pen-point and designed to check the flow of ink through the feed-opening therein is a hygroscopic or absorbent agent, preferably consisting of raw cotton. This material is confined between the tip of the pen-point and the lower end of the extension, and by adjusting the sleeve 12 it may be. compressed to increase its density, and thereby check or regulate the flow ofink through the feed-opening in the pen-point. The pen-point is preferably made of glass, and the other parts described are preferably made of hard rubber, but may be made of any suitable well-known or desired material. To prevent the escape of ink between the penpoint and the extension, the extension may be provided with a packing of cork or other suitable material, (indicated by the numeral 13.)

14 denotes a cap which when the pen is not in use may be engaged with the pen-point and when the pen is in use may be engaged with the neck 3 and head 4, as shown in Fig. 2. This cap is provided with the usual ventopening 15.

As the operation of the pen is substantially the same as that described in the patent here inbefore referred to, it is not thought necessary to repeat the operation herein.

The construction admits of theexpeditious assemblage and disassemblage of parts for the purpose of renewal, repair, orcleansing. By providing a removable pen-point when the same becomes worn or damaged it may be replaced with a new one. By providing means for varying the density of the absorbcut or hygroscopic material the flow of ink through the pen-point may be regulated to a,

Various changes in the form, proportion,

and details of construction maybe made Withinthe scope of the invention Without departing from the spirit or sacrificing any of the advantages thereof.

Having thus described my invention, What I claim, anddesire to secure by Letters Patcut, is 1 v 1. In a pen of the character described, the combination with a barrel or reservoir and a pen-point, of an absorbent material arranged to retard the flow of ink from one to the other, and means for varying the density of said material, for the purpose of regulating the flow of ink, substantially as set forth.

2. In a pen of the character described, the

. combination with a barrel or reservoir, of a tubular pen-point communicating therewith,

absorbent material located therein to retard the flow of ink, and means to vary the density of said material, substantially as set forth.

3. In a pen ofvthe character described, the combination with a barrel or reservoir, of a tubular pen-point, absorbent material located therein, a tubular extension projecting from the barrel into the pen-point, and means for sliding the pen-point upon the tubular exten- 1 sion to vary the density of the absorbent material within the pen-point, substantially as set forth. 7

4. In a pen of the character described, the combination with a barrel or reservoir, of a tubular pen-point, absorbent material located therein,-a'tubular extension projecting from the barrel into the pen-point, and means for sliding the pen-point upon the tubular extension to vary the density of the absorbent material within the pen-point, said means consisting of a couplingrsleeve loosely connected to the pen-point and having a screw-threaded connection with the barrel or reservoir, substantially as set forth.

5. In a penof the character described, the combination with an open '-ended barrel or reservoir, of a capillary-tube removably connected with one end of the barrel or reservoir and open at each end, substantially as set forth.

6. In a pen of the character described, the

combination with an open-ended barrel or reservoir provided with a screw-threaded neck, of a capillary tube open at each end and provided with a screwthreaded head to engage the neck, substantially as set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
