UNITED STATES PATENT OFFICE.
HERMANN MADEHEIM, OF BROOKLYN, NEW YORK.
IMPROVEM ENT IN FOUNTAIN-PENS.
Specification forming part of Letters Patent No. 57,162, dated August 14, 1866.
To all 'whom it may concern:
Be it known that I, H. MADEHEIM, of the city of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Fountain-Pen and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l represents a longitudinal central section of this invention. Fig.`2 is a partial side elevation of the same. Fig. 3 is a transverse section of the same, taken in the plane indicated by the line a' w, Fig. l. Fig. 4 is a similar section, the plane of section being iudicated by the line y y, Fig. l.
Similar letters of reference indicate like parts.
rThis invention consists in a fountain -pen with a hollow piston-rod, stationary piston, and movable pump barrel, in such a manner that the barrel or reservoir can be llcd from either end and a comparatively large supply can be taken in by the pen; further, in the arrangement of a regulating-screw with airholes, in combination with the pump-barrel, in such a manner that by turning such screw the iiow of ink to the pen can be regulated at will; also, in apartition extending ina 1011- gitudinal direction from one end of the inkretainer to the other, for the purpose of preventing lumps contained in the ink from passing out to the nib of the pen; further, in the arrangement of stops at the end of the body of the pen-holder in such a manner that the barrel, on being pushed down, is prevented from closing up tight to such body, and the piston-rod is prevented from getting soiled by the ink; finally, in the arrangement of airchannels in the body of the pump-barrel in such a manner that moisture is prevented from collecting on the piston-rod, and the ink is prevented from ilowing out by capillary at# traction.
A represents a fountain-pen, which is provided with a piston, a, from which extends a hollow piston-rod, b, to 'the ink-retainer c, which is situated close under the pen d. The piston a Works in a barrel, c, the upper end of which is closed by a screw-plug, f.
By inserting the pen in the inkstand and moving the barrel up and down on the piston ink is drawn in and the reservoir or fountain of the pen is filled, said reservoir consisting of the interior space of the barrel and of the hollow piston-rod. A
The communication between the reservoir and the ink-retainer can be closed or op'ened by a valve, g, and the ilow of ink to the pen can be regulated by turning the. screw-plugf, which is provided with vent-holes h.
The ink-retainerc is furnished with a longitudinal partition, t', (see Fig. 4,) which serves to prevent lumps contained in the ink from flowing' to the nib of the pen.
When the barrel e is pushed clear down its inner end, instead of closing up tight on the inner end of the body of the pen-holder, meets stops j, (see-Figs. 2 and 3,) and thereby the accumulation ot moisture on the piston-rod or on said ends is prevented, and the piston-rod remains clear and free from ink. For the same reason air-channels k are made in the body ofthe barrel, for itis well known that when two surfaces of hard rubber are close together moisture accumulates thereon, and by this moisture the ink is attracted and the piston-rod and other parts are soiled.
In my pen this diiiiculty is avoided by the stops j and airfchannels h.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. The combination of the hollow piston-rod b, piston a, ink-retainer c, movable barrel e, and pen d, all constructed and operating substantially as and for the purpose described.
2. The longitudinal partitioni in the ink-retainer c, substantially as and for the purpose described. K
3. The stops j on the inner end of the body of the pen-holder, or on the end of the barrel e, for the purpose set forth.
4. The air-channels k in the body of the barrel, as and for the purpose described.
HERMANN MADEHEIM.
