FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent No. 369,016, dated August 30, 1887.

Application filed June 6, 1887. Serial No. 240,4l4. (No model.)

To all whom it may concern:

Be it known that I, R'HoDEs LOCKWOOD, of

Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Fountain-Pens, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to fountain-pens,and has for its object to improve the construction of the same, whereby the ink may flow freely from the pen,yet without dropping, which would cause blotting of the paper.

My invention consists, essentially, in a fountain-pen,in the combi11ation,with the pensection, of a feeder provided at its upper side or top with a slot, a, substantially as will be described. 1

My invention also consists, in afountain-pen, in the combination, with the pen-section, of a feeder provided at its upper side or top with a slot, (1, and a plug inserted into the said feeder, and between which and the feeder the pen is inserted, substantially as will be described.

Other features of my invention will be pointed out in the claims at the end of this specification.

Figure 1 is a top view of a fountain-pen constructed in accordance with my invention, it being ready for use, Fig. 2, a section of Fig. 1 on line a: w, the plug, between which and the feeder the pen is inserted, being in elevation Fig. 3, a sectional detail to be referred to, the section being taken on line y y, Fig. 4.; Fig. 4, a top View of Fig. 3, and Fig. 5 a modification to be referred to.

The fountain or reservoir a, to contain ink, and made of india-rubber or other suitable or usual material, is provided with a cap, a, adapted to be fitted over the end of the said fountain, as shown in Fig. 2, when the pen is to be used, and to be fitted over the pen section or nozzle a: whenthe pen is not in use.

The pen section or nozzle a is provided with screw-threads at one end to engage threads on the inner side of the reservoir a, as in fountainpens now in use.

The pen section or nozzle of is made tubular, as shown, to receive within it a substantially tubular feeder, a provided with an extension or arm, a, the said arm in practice being adapted to rest upon a pen, w, the extremity of the said arm preferably overlapping the slit in the pen. I

The tubular feeder a is provided with a preferably inclined slot, a, at its top, the said slot extending, as shown in Fig. 4, from the rear of the arm a the length of the tubular feeder o the said slot diverging toward the rear of the said feeder.

The feeder a receives within it a plug, b, made to fit the said feeder somewhat snugly, but so as to be readily inserted into and removed from the said feeder, as desired.

The plug 1), as shown, is reduced or made smaller in diameter at its front end to leave a shoulder, 12, against which the pen a butts when the said pen is placed in position between the said plug and the feeder (R.

The plug 12, as shown, is provided with a groove or channel, I)", (see Fig. 3,) extended from the shoulder 11 to the rear end of the saidplug, the said slot forming, with the feeder a a passage for the admission of air into the fountain or reservoir a, the said plug being inserted into the feeder a so as to bring the air-passage b at the bottom' or under side of the feeder and substantially opposite the pen.

In operation the ink in the reservoir on flows through the slot a, from whence it is carried, by capillary attraction,to the points of the pen by the arm a, which, resting upon the top of the pen, prevents a drop of ink on the said pen from being separated from the feeder-arm when pressure is exerted upon the pen to produce heavy lines or shading, thus obviating dropping of the ink, which would occasion blots upon the paper or other material being written upon.

Instead of extending the slot a to the rear end of the tubular feeder, the said slot may be extended but part way toward its end,as shown 7 in Fig. 5, and when this form of tubular feeder is used the plug 12 will be inclined or beveled, "as at c,"Fig. 5, so as to connect the slot a with the reservoir a, the said beveled or inclined plug 1) having the slot 1) at its under side to form the air-passage.

I claim 1. In a fountain-pen, the combination, with the pen-section and reservoir, of a feeder having an air-inlet into the reservoir, and a slot, a, constituting an ink-outlet, a pen-socket, and an extension or arm, a, projecting beyond the said slot over and above the pen, substantially as set forth.

2. In a fountain-pen, the combination, with the pen-section, of a feeder provided at its upper side or top with a slot, a, and a solid arm, a, extending over the slit in the pen and above the pen, and a plug inserted into the said feeder, and between which and the feeder the pen is inserted, substantially as described.

3. In a fountain-pen, the combination, with the pen-section, of a feeder provided at its upper side or top with a slot, a, and a plug, 6, provided with a groove or channel, 0, substantially as described.

4. In a fountain-pen, a pensection and a tubular feeder, a, provided with an arm, a, and having a tapering slot, a, at its upper side, combined with a plug, 1), adapted to be inserted in said tubular feeder, and with a pen inserted between said plug and feeder, the arm of the feeder being adapted to bear upon the upper side or top of the pen, substantially as described.

5. In a fountain-pen, a pen-section and a tubular feeder, a, provided with an arm, a, and having a tapering slot, a", at its upper side, combined with a plug, 1), having a groove or channel, Z), adapted to be inserted in said tubular feeder, and with a pen inserted be tween said plug and feeder, the arm of the feeder being adapt d to bear upon the upper side or top of the pen, substantially as de scribed.

6. The reservoir a, the tubular nozzle a", screwed into it, and the feeder composed of an arm and tubular shank having a tapering groove, combined with a solid plug provided with a vent-passage and inserted within the tubular shank of the feeder, a space being left between the plug and feeder, into which the pen to be used may be forced, substantially as described.

7. The reservoir a, the tubular nozzle 07, and the feeder composed of an arm and tubular shank having a groove, combined with a solid plug provided with a vent'passage and inserted within the tubular shank of the feeder, a space being left between the plug and feeder, into which the pen to be used may be forced, substantiall y as described.

8. In a fountain-pen, a pen-section and a tubular feeder provided with an arm, a, and having a slot, a", at its upper side, combined with a plug, 1), adapted to be inserted in said tubular feeder, and with a pen inserted between said plug and feeder, the arm of the feeder being adapted to bear upon the upper side or top of the pen, substantially as described In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.
