Description

F 4, 30- F. A. VAN SANT FOUNTA IN PEN ATTACHMENT Filed Aug. 14, 1928 Inventor 4 7 577 Sal/ZZZ xlttornqy Patented Feb. 4, 1930 UNITED STATES FRANKLIN A. VAN SANT, F MADISON, WISCONSIN- FOUNTAIN-PEN ATTACHMENT Application filed August 14, 1928. Serial No. 299,628.
This invention relates to an improved accessory for fountain pens, preferably in the form of an attachment which is embodied in the pen structure, for regulating the rigidity or flexibility of the writing pen.
More specifically speaking the invention has reference to a longitudinally adjustable device, constructed to bring pressure to bear upon the flexible pen to regulate the flexing action thereof with respect to the ink feed.
My principal aim is to provide an appliance of this class which can be embodied in the present-day type of fountain pen or upon the ordinary writing pen, the invention being characterized by exceptional simplicity in construction and arrangement whereby to minimize the cost of production and sale.
Another object is to provide an invention of this character which can be readily adjusted by the user to render it suitable and desirable to his own personal need.
Other features and advantages of the invention will become apparent from the following description and drawing.
' In the drawing Figure 1 is a top plan view of a fountain pen revised, and constructed in accordance with the present invention.
Fig. 2 is" a side view thereof, with portions shown in section to disclose the arrangement of parts more clearly.
Fig. 3 is an enlarged fragmentary detail view showing the friction filling cap and the cooperating scale.
Referring to the drawings by numerals, it will be seen that the pen barrel 4; is of con ventional construction, it being of usual configuration and hollow in construction and having a reduced shouldered portion 5 at one end. Incidentally this portion 5 as shown better in Fig. 3, is equipped with a measuring scale 6. At the left hand end of the barrel is the customary ink feed 7, and writing pen 8. At the opposite end is-a cap 9 having snug friction fit on the reduced portion 5, inorder that it may be slid back and forth for cooperation with the scale.
The principal improvement constitutes the pressure adjusting device which embodies a rod 10 extending through the opposite ends of the barrel and-interposed between the in terior of the barrel and the rubber bag 11 asbears upon and has sliding contact with the pen 8. The opposite end of the rod extends through an eccentric opening in the portion 5, where it is fastened to the cap 9 by a set screw or the like as shown in Fig. 3.
With this arrangement, the cap 9 is adjusted back and forth from the part 5 for cooperation with the scale, whereby to produce sliding movement of the rod 10 and a consequent adjustment of the head 12, back or forth on the pen 8. This permits the rigidity or the flexibility of the pen to be adjusted to suit different requirements.
The scale enables the user to make the adjustment accurately. The invention is intended to be embodied in pen structures, sold for individual use, or for special use by dealers in determining the gage of a pen to be sold to a particular individual. The invent-ion may be marketed and sold in the form shown in the drawings, to enable an individual writing to change the-flexibility of his own pen to'suit his needs.
Incidentally it may be for different kinds of work, the user would want a fine line or a medium line, or a heavy line, and this can be accurately accomplished with the present attachment in place.
It is thought that the purpose, the construction, and the advantages of the inven- -tion will be quite clear after considering the description in associationwith the drawings, for which reason a more lengthy description is regarded unnecessary.
Minor changes in the shape, size and re arrangement of parts coming within the field of invention claimed may be resorted to if desired.
Having thus described my invention, what I claim as new is 1. In a structure of the class described, in combination, a pen including a body having a, flexible pen at one end, a rod slidably mounted on the body and provided at one end with a head in sliding pressure contact with said gen, and adjusting means for said rod carrie by said body.
2. In a structure of t e class described, a pen including a hollow body, a flexible pen point carried by said body, a rod slidably mounted on and extending through said body, means on one end of the rod bearing slidably against said pen point, and means on the opposite end of the body for adjusting said rod.
3. In a structure of the class described, a pen including a hollow body, a flexible pen carried thereby, a rod slidably mounted upon and extending through said body, means on one end of the body for sliding and pressure contact with said pen, means on the opposite end of the body for adjusting said rod, said 1ast-named means comprising a cap adjustably mounted on the body.
4. In a pen structure of the class described, a barrel of hollow construction having a reduced shouldered portion at one end and having an ink feeder at the opposite end, a flexible pen point at the last-named end of the said barrel cooperable with said ink feeder, a cap slidably mounted on said reduced shouldered portion, a rod in said barrel slidable through the opposite ends thereof and connected at one end to said cap, and a head on the opposite end of the rod cooperating with said pen point.
In testimony whereof I aflix my signature.
