FouNTA|N-PEN- SPECIFICATION forming part of Letters 'Patent No. 533,350, dated January 29, 1895.

Application filed June 14,1893.

To all whom it may concern.'

Beit known that I, WALTER F. CUsHING,'a citizen of the United States, residing at Medford, in the county of Middlesex, State of Massachusettshave invented a new and useful Improvement in FountaimPens, of which the following is a specification.

The object of my invention is to provide a fountain pen in which the ink will be fed from the reservoir with great regularity, and my invention consists in the improved construction and arrangement ot the ink feeding parts of the point section, as hereinafter fully set forth.

In the accompanying drawings: Figure 1, represents alongitudinal section of a fountain pen provided with my improvement. Fig. 2, represents a side view of the inner tube of the Fig. 3, represents a transverse section taken in the line 3, 3, of Fig. 2. Fig. 4, represents a transverse section in the line 4, 4, of Fig. 2. Fig. 5, represents a longitudinal section of the inner tube removed from the outer tube of the point-section. Fig. 6, represents an edge view of the feed-bar.

In the accompanying drawings, A represents the hollow barrel, which forms the ink chamber or reservoir B, and C is the pointsection, which screws into the end of the barrel A. Within the outer tube a of the point-V section, is placed the frictionally held .cylindrical tube b, which is provided at its outer end with longitudinal slits d, adapted to reat its inner end with a longitudinal slot c, extending through the wall of the inner tube b, from its central cavity, to the wall of the outer tube a; the said slot c being made through that side of the tube h, which is opposite to the under side of the pen D. The inner tube b is preferably made with an enlarged bore e at its lower portion, with a `smaller bore f extending from about its middle, to the upper end, and at the side of the bore f opposite the slot c, is made the interior notch g, adapted to form an opening between the wall of the tube b, and the edge of the feed bar F, for the passage of the ink. The feed bar F is made of a thin strip beveled at its lower end, as

shown in Fig. 5, so that when the feed bar is Serial No. 477,562. (No model.)

forced downward into the point section C, the tube b will be wedged tight, the slot c being so made that a beveled surfaced willbe formed at the outer side of the wall of the tube b, to receive the tapering point j of the feed-bar.

The shank of the pen D, is placed in the holding slits d, in the sides of the inner tube b, which slits are inclosed by the outer tube a, and over the pen D, is placed the ink guide G, which extends upward into the cavity of the inner tube b, in which it is frictionally held, leaving a passage at each side of n"the guide for the downward dow of ink; and projecting outwardly over the top of the pen, to guide the downward flow of ink to the nibs, and between the upper end of the guide G, and the beveled end of the 'feed-bar F, is formed the small ink chamber K.

I claim as my inventionl. In a fountain pen, the combination with the outer tube of the point section, and the cylindrical frictionally held inner tube provided at itsV outer end with slits adapted to receive the shank of the pen, and at its inner end with a longitudinal slot extending through the wall of the 4said inner tube, from its central cavity, to the wall of the said outer tube, and located at that side of the said inner tube, which is opposite the under side of the pen, of the pen, held in the slits ot the inner tube, the feed bar frictionally held in the said slot of the wall of the inner tube, and the frictionally held ink-guide, extending upward into the cavity of the inner tube wherein it is frictionally held, and projecting outwardly over the top of the pen, substantially as described.

2. In a fountain-pen, the combination with the outer tube of the point section, and the inner tube slotted at its side, and beveled at its lower end of the slot, of the beveled feedbar in the slot and adapted to tighten the in- `ner tube within the outer tube,substantially as described.

3. In a fountain-pen, the combination with the outer tube of the point-section, and the inner tube having a bore of different diameter and slotted at one side, of the feed-bar held -in the slot of the inner tube, the pen, the inkguide above the pen, the chamber between IOO the end ofthe ink-guide, andthe feed-bai', subthe pen, and the ink-guide' above the pen, sub;- stantially as described. stantially as described.

4. 'In a fountain-pen, the combination with t v the outer tube of the point-section, and the VALFER F' GUbHING 5 inner tube slotted at one side and provided WVitnesses:

with an interior notch at the other side, of SOCRATES SoHoLF'IELD, the feed-bar held in the slot of the inner tube, CHARLES S. MURCH.
