SPECIFICATION forming part of Letters Patent No. 655,731, dated August 14, 1900.

Application iiled January 14, 1898. Serial No. 666,701. (No model.) i

To LLZZ whom it' may concern:

Beit known that I, PnRoY E. Pinson, a citizen of the United States, residing at Galion, in the county of Crawford and State of Ohio, 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.

The chief objection against the use of fountain-pens is their susceptibility to discharge the ink too freely, thereby causing blots and soiling of the fin gers. This is due principally to the weight of the column of ink in the holder exerting a direct pressure at the lower or delivery end thereof and to the expansion of the air confined in the upper endof the holder after a part of the ink has been used when grasping the pen to begin writing. Y

This invention has for its object to relieve the pressure upon the ink 'at thel point of supply to the pen, to obviate blotting, to prevent an overfeedpf the ink, and to secure the advantages of having the pen arranged obliquely to the holder.

The invention consists of a holder constituting a reservoir, a reducing connection at the lower end of the holder having a lateral extension, and a supplemental reservoir ob` liquely arranged with reference to the holder and receiving the feed mechanism and pen and having its upper end forming an airchamber.

The invention also consists of the novel features and peculiar combinations of the parts, which will be hereinafter more particularly set forth,`illustrated, and finally claimed.

Referring to the'drawings forming a part of this specication, Figure 1 is a front View of a fountain-pen constructed in accordance with and embodying the vital features of the invention. Fig. 2 is a central longitudinal section thereof. Fig. 3 is an enlarged view of the tip or nozzleto which the pen and feeder are applied Fig. 4 is a detail view of the feeder.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The handle A is tubular and constitutes a reservoir or fountain for the supply of ink,

by means of which the pen is replenished when in service. A cap F closes the lower end of the reservoir-handle A and is provided with a reduced or contracted passage E, through which the ink from the reservoir finds its way when passing to the pen. This cap has a screw-thread connection D with the handle, so as to be removed when it is required to charge the reservoir or clean the same. The lower end of the cap F forms a receptacle in which sediment collects, thereby keeping the ink-supply to the pen in a perfectlyiuid condition, whereby clogging and gumming are avoided. A short tube I-I or connector has its end portions reduced and threaded, one end being let into an opening in a side of the cap F and the opposite end receiving the cap J, which is obliquely disposed with reference to the part H and the reservoir-handle A. The part II is in effect a coupling and has screw-thread connection G with the cap F and a like connection I with the cap J. The passage through the coupling II is considerably smaller than the area of the opening in the handle A, and corresponds approximately with the passage or contracted portion E of the cap F, and serves to materially reduce the pressure of the ink at the lower end of the handle. The tip or nozzle K has its upper end reduced and iitted to the cap J by a screw-thread connection L and is in alinement with said cap and constitutes therewith a supplemental or auxiliary reservoir. The portion of the cap .I above the passage of the coupling H constitutes an air-chamber, which serves in a measure to equalize the pressure of the ink and materially assists in preventing a too-rapid liow thereof and a consequent blotting of the writing and soiling of the fingers by an excessive discharge of ink. The pen end and feeder N are fitted into the nozzle or tip K, the shank of the feeder being bifurcated and the nib offset and overlapping the outer side of the pen, whereby the ink is directed to the pen in the best possible manner.

The oblique disposition of the supplemental reservoir results in a twofold advantagenamely, in a material reduction of the prese IOO lects heavy particles in the ink, so that the ,supply to the pen will be free and ample for every style of writing, being an essential requisite in an instrument of this class. The air-space in the upper end ofthe supplemental reservoir provides a relief for the temporary pressure resulting from expansion of the air in the holder` A when first grasping the pen preparatory to writing, thereby obviating blotting, which is the result of a too-rapid fiow of ink at the outset. By having the parts connected by screw-thread joints in the manner set forth they are readily accessible for cleaning and any desired purpose.

The cap C for closing the lower end of the nozzle or tip K and protecting the point of the pen in the usual manner is adapted to be detachably fitted to the reduced end of the reservoir-handle when removed from the nozzle, so as not to be accidentally misplaced. This is most clearly shown in Figs. l and 2 of the drawings.

Having thus described the invention, what is claimed as new is- 1. In a fountain-pen, a reservoirhandle, a supplemental reservoir at one side of the handle and having the penl applied thereto, and an intermediate connection between the handle and supplemental reservoir and having a contracted passage, whereby the pressure at the delivery end of the fountain is-materially reduced, substantially as set forth.

2. In a fountain-pen, a reservoir-handle, a supplemental reservoir at one side of the handle and having the pen applied thereto, and a lateral or intermediate connection between the handle and supplemental reservoir and connecting with the handle a short distance above its lower end, whereby a settling-chamber is provided, substantially as described.

3. A fountain-pen comprising a reservoirhandle, a supplemental reservoir at one side of the handle and having an air-space at its upper end and provided at its lower end with the pen, and an intermediate connection between the handle and supplemental reservoir, substantially as set forth.

4f. In a fountain-pen, a reservoir-handle having a settling-chamber at its lower end and supplemental reservoir at one side of the handle and having an air-space at its upper end and provided at its lower end with the pen, and an intermediate connection between the handle and supplemental reservoir and having a contracted passage, substa ntially as set forth.

5. A fountain-pen comprising a reservoirhandle closed at its lower end, a supplemental reservoir obliquely disposed at one side of the handle and provided at its lower end with the pen, and an intermediate connection having a contracted passage between the lower end of the reservoir-handle and the upper end of the supplemental reservoir, substantially as described.

6. In a fountain-pen, a reservoir-handle, a cap closing the lower end of the handle and having a lateral opening and a contracted passage, an obliquely-disposed supplemental reservoir comprising a cap and tip, and a coupling connecting the cap of the handle with the cap of the supplemental reservoir, substantially as specified.

'7. As a new article of manufacture a penstock comprising a reservoir-tube, a lateral branch having a contracted passage at the lower end thereof adapted to retard the flow of ink, and an extension at the end of said lateral branch carrying a feed mechanism, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses. p
