HEINRICH GERST, OF NEW YORK, N. Y., ASSIGNOR OF ONF-HALF TO PAUL WISNIEWSKI, OF SAME PLACE.
SPECIFICATION forming part of Letters Patent No. 684,685, dated October 15, 1901.
Application filed January 18, 1901- Serial No. 43,733. (No model.)
To all whom, it may concern:
Be it known that I, HEINRICH Gnnsr, a citizen of the United States, and a resident of New York city, county and State of- New York, have invented certain new and useful Improvements in Fountain-Pens, of which the following is a specification.
This invention relates "to a fountain pen which is composed of a socket adapted to be projected over a finger and of a pair of concentric conical pen-points by which light or heavy lines may be readily formed.
In the accompanying drawings, Figure l is a perspective view of my improved fountain pen, showing it in use. Fig. 2 is a longitudinal section thereof. Fig. 3 illustrates in section the component parts of the pen. Fig. 4c is an enlarged cross-section on line 4 4, Fig. 3; and Fig. 5, a longitudinal section through the cap.
The pen is composed of a tapering socket a, which is open at the upper end and closed at its lower end. The socket a is embraced by anink-well b, which gradually diverges from the socket from top to bottom, so as to hold a suflioient charge of ink. From the lower end of the well 7) projects a flanged tubular collar 0, adapted to receive two con-- centric conical pen-points d and e and the usual cap f. The inner pen point d is in-' finger, Fig.1, by the motion of which the writing is efiected, so that much fatigue is saved. The ink flows from the well I) through the slits of the inner pen-point into the space between the pen-points and thence through the outer pen-point upon the paper. By varying the distance between the ends of the pen-points the pen may be readily adjusted to make light or heavy lines.
The inner slitted conical pen-point constitutes a free ink-feeder, which may be easily cleaned either by pressing it upon the paper or by drawing a wiper through it.
What I claim is A fountain-pen provided with an inner penpoint having a slitted conical nib, and-with an outer pen-point that surrounds the inner pen point and has also a slitted conical nib, substantially as specified.
Signed by me at New York city, county I .andState of New York, this 17th day of January, 1901.
