CHARLES FREDERICK I BILLAU, 0F CEDAR RAPIDS, IOJVA.
FOUNTAIN-PEN.
Specification of Letters Patent. Pgltqgntgd fdgf 31 3115,
Application filed May 16, 1914. Serial No. 838,985.
To all whom it may concern:
Be it known that I, CHARLES F. BILLAU, a citizen of the United States, residing at Cedar Rapids, in the county of Linn andv State of Iowa. have invented certain new and useful Improvements in Fountain-Pens; and I do hereby declare the, following to be a full. clear. and exact description of the invention. such as will enable others skilled in the art to which it appertains to make and use the same. i
My invention relates to certain new and useful in'iprovements in fountain pens of the self-filling type and resides in the provision of a novelly constructed pen which com- Urlses self filling means that is simple as to constrlu-tion, reliable and etlicient in opera tion and cheap to manufacture.
An important object of my invention is to provide filling means in which the operating rod is removable from the piston.
Another important object of my invention is to provide a piston that is slidable within the magazine barrel of the pen and formed in such way that the piston rod when inserted into the barrel will readily find the screw threaded opening formed in the piston.
Another important object of my invention is to provide novel means whereby the piston rod when i'vithdrawn is freed from ink and prevented soiling of the fingers.
Another important object of my invention is to provide means whereby the packing washer for th piston may be expanded.
Another important object of my invention is to provide a' piston having a removable piston rod. said piston being provided with a roughened surface arranged to coact with some part of the magazine barrel to prevent rotation of the piston while the rod being unscrewed therefrom.
The invention further aims to improve and throughout the several views of which similar reference numerals designate corresponding parts: Figure 1 is a longitudinal sectional view taken through a pen showing my improved construction in assen'ibled po sition. Fig. 2 is a fragmentary longitudinal sectional view showing more clearly the detail construction of my improved pen, and Fig. 3 is a cross sectional view taken on line 3-3 of Fig. 2 showing the roughened surface on the outer end of'the piston head to prevent turning of the piston upon the unscrewing of the rod therefrom.
Referring to the drawings by characters of reference, the numeral 1 designates as an entirety the magazine barrel of a fountain pen and that is attached in the usual manner at one end to the pen holding and feeding portion 2 of the pen which carries the pen point 3. The outer or other end of the magazine barrel 1 is open and adapted to be closed by a frusto conical closure plug 4. This closure plug l is provided with a re duced cylindrical portion 5 at its outer end and said cylindrical portion 5 is disposed in extended relation to the adjacent end of the barrel. A. passage or opening i3 is formed longitudinally through the frusto conical closure plug 4: and at its outer end communicates with theconcaved outer face 7' of the cylindrical extension portion The .purpose of the concave portion 7 at the outer The pumping mechanism for filling the farthest removed" from that in which the aperture 11 is formed is convex as-at 13 and centrally of the convex portion is provided with a screw thr aded extension let. A. packing washer or ring 15 is mounted upon the extension 1 1 A. concave convex washer plate 16 is mounted upon the screwthreaded extension 14: and engages the lower or inner face of the packing ring or washer 15. A
nut 17 is turned upon the threaded exten-' sion 14 and forces the frusto conical washer 16 into engagement with the packing ring 15. The concaved face of the washer 16 is forced into engagement with the packing ring 15 and the engagement-of the packing ring 15 with the convex face 13'o-f the body portion and concaved face of the washer 16 provides for the expansion of the packing ring upon the screwing up of the nut 17. The rod 12- is provided at its outer end with a knurled or otherwise roughened knob 18 and is inserted through the plug 4: and at its inner screw threaded end is connected with the body portion 10 after the manner previously described. J
As a means for preventing the turning of the piston. head 9' when it is desired to unscrew the rod 1 I provide a roughened surface in the form of corrugations, or projections 19 upon the outer face of the body portion 10 which is concaved as at 20. The concave-dface 20 on the body portion 10 serves to properly guidethe screw threaded terminal of the rod 12 when the rod is inserted into the magazine barrel 1' to be turned in the aperture il in the'body portion 10 of the piston head 9. When it is.
desired to unscrew the rod 12 thevbody portion 10 is positioned with the projections 01'. corrugations 19 in engagement with the innor end of the plug 1. The projections 19 grip the inner end of the plug and serve to hold the piston head 9 against rotation.
. It will be readily seen that should any ink get between the piston head '9 and plug 4 there is possibility of its oozing out through the opening or passage 5 formed in the plug 4. The closure plugs in being provided with a concave'd face 7 at one end and of resilient material serves to prevent :the' soiling of the fingers, that is the withdrawal of the rodwith ink thereon.- It will be readily seen that through the mediurnl of the plug 4- ink will not be gotten upomthe fingei's from the rod 12 after the Withdrawal -lof;,the rod. It will also be noted that by moving the piston head 9 up and down within" the mag'aZine barrel the feed passage of the pen is cleansed by such action. The
piston acts to force any matter clogged in the feed passage in being moved back and forth in the magazine holder 1. It Will be readily seen that the rod 12 may be completely removed with relation to the pen and ink cannot get beyond the piston head 9 thus insuring against'soiling of the hands due to leakage of the ink. The concavedf portions 20 and 7 provide 'forthe proper guiding of the rod 12 when the rod is'to be inserted into the barrell. I
It will bereadily seenwith reference to the foregoing description and accompanying drawings that I have provided a,v simple. and inexpensivepen which is reliable and efiicient in operation and cheap to manufacture,
One of the most essential points of my invention: is the-fact that rod 12 may be readily removed entirelywith respect to the pen and withoutrin any way interfering with the pen performing its properfunction. It will also be readily seen that the rod 12 may be properly insertedjfor pumping operation in a most reliable and expeditious manner. v
In practice, I have found that the form of'my invention, illustrated in the drawings and referred to in the above description, as
the preferred embodiment, is the most eflicient and. practical; yet realizing that the conditions concurrent with the adoption of my advice will necessarily vary, I desire to emphasize the fact that various. minor changes in details of construction, propor-' tion and arrangement of parts may be resortedto, when required, without sacrificing any of the advantages of my invention, as set forth. f a
What is claimed is In a fountain pen, a magazine barrel, a
relativelysoft plug inserted in one end of said barrel having a tapered inner end extending a distance into said barrel, a plston slidably mounted within said barrel andv
