T. MIURA.
STYLOGRAPH.
APPLICATION FILED APR. 8. 1915. RENEWED OCT. 18. I916.
Patented Nov. 21, 1916.
M/VE/I/TUR ATTORNEY UNITED STATE -PATENT omen TOMIJI MIURA, OF SEATTLE, WASHINGTON.
STYLOGBAPH.
Application filed April 8, 1915; Serial No. 20,054.
To all whom it may concern:
Be it known that I, ToMIJI MIURA, a citizen of Japan, and a resident of Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Stylographs, of which thefollowing is a full, true, and exact specifica tion.
My invention relates to stylographs and more particularly to self feeding ink using stylographs and has for its principal object: to provide a device of this general character which has a sharp and solid point which is adapted to make a clean and even mark and also will give a true reproduction when used with a carbon sheet beneath a sheet upon which the stylograph is writing.
A further object is to provide a stylograph or fountain pen i'eed stem in which a plurality of feed grooves are used, all of which are upon the outside of the said stem,
" which arrangement gives a device which does not easily clog and which is equally as efficient even though one or more feed grooves are clogged. stem is much more easily cleaned than the usual form of Stem. A further object is to provide a resilient feed control cap which automatically controls the supply of ink which flows to the writing point.
' Other objects w1ll appear as my invention is more fully explained in the following specification, illustrated in the accompanying drawings and pointed out in the ap pended claims.
In the drawings, Figure 1 is a general elevation of a complete stylograph or fountain pen with parts broken away. Fig. 2 is an enlarged central section of my improved writing point and feed stem. Fig. 3 is a sectional elevation on line 3 -3 of Fig. 2. Fi a is a sectional elevation on line H 0 Fig. 2.
Referring more particularly to the drawings, numeral 1 designates a barrel of a fountain pen which is chambered as at 2 to receive an ink supply. The open end of the barrel is internally threaded to receive a threaded end 3 of a tip 4: which is shouldered as at 5 and 6. The tip is internally chambered as at 7 and 8, the former being A feed stem 9 is adapted to fit snugly into the chamber 8 and to be frictionally held in place. The stem is slightly longer than the chamber and is provided wi h a tapered wrltmg point 10 Specification of Letters Patent.
Patented Nov. 21, 1916. Renewed October 18, 1916. Serial No. 126,459.
and a plain shouldered portion 11 at the opposite end. The main body 9 of the stem has longitudinal grooves 12. The grooves 12 also extend to the end of the point 10-and are proportioned in size to the diameter of the point. The upper ends ofthe grooves 12 do not run to the end of the body 9 of the stenrwhich is set so that the grooved portlon projects slightly into the chamber 7. The stem is turned down at 13 until the grooves 12 are but very small where they cross the shank. A resilient feed control cap or washer l4 fits vthe shanked portion 13 tightly and also fits up tightly agamst the end of the tip. The function of the cap 14 is to regulate the flow of ink from the grooves 12 above the cap to the said grooves in the point. The cap 14 regulates the flow because it forms a tight dam or gasket around shank 13 and only allows a limited amount of ink, to the capacity of the reduced grooves, to pass it. The ink follows the grooves 12 down to the cap 13 which regulates its flow and on to the point 10 for writing. It will be understood that the stem is of a hard material-such as glass or hard rubber and that the point 10 is quite fine.
'When my improved pen is used, it is possible to make a carbon popy in the usual manner as the point 10 may be used quite heavily on the paper and also because it will mak but a single mark, whereas a split pen makes a double mark on the carbon copy.- The point of my device being of solid and uniform section, does not get out of order as an ordinary pen point.
It will be apparent that one or more feed grooves 12 may become clogged without stopping the flow of ink to the point.
While I have shown a particular form of embodiment of my invention, I am aware that many minor changes therein will readilysuggest themselves to others skilled in the art without departing from the spirit and Scope of the invention, and I therefore, desire to avoid being limited to the'exact form shown and described, except as defined in the appended claims.
Having described my invention, what I claim as new and desire to protect by Letters Patent, is
1. In a stylograph or fountain pen, the combination of a hollow barrel, a chambered tip attachable tothe barrel, a grooved feed stem fitting within the chamber of the said 2. In a stylograph or fountain pen, the.
combination of a hollow barrel internally threaded at one end, a tip having internal connected chambers and an externally threaded portion which is adapted to screw into the barrel, a feed stem fitting snugly in the smaller of the said chambers and projecting from both ends thereof, a tapered point on one end of the feed stem and a shanked portion between the body of the stem and the said point, the said stem having longitudinal external feed grooves which run from the point to near the opposite end of the body of the stem, a resilient feed regulating cap fitting snugly around the shanked portion of the stem and against the outer end of the tip, whereby the amount of ink flowing from the barrel along the feed grooves to the point, is regulated.
3. In a fountain pen, the combination of a barrel adapted to hold ink, a chambered tip attachable to said barrel, an externally grooved and pointed feed stem fitting with- .in the chamber of the tip, and a resilient feed regulating cap attachable to the said stem, whereby the amount of-ink flowing to the point is regulated.
