Specification of Letters Patent.

Patented Apr. 8, 1919.

Application filed November 17, 1916. Serial No. 131,955.

To all whom it may concern:

Be it known that I, BENJAMIN R. JonLY, a citizen of the United States of America, residing at Raleigh, in the county of Wake and State of North Carolina, have invented certain new and useful Improvements in Fountain-Pens, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to fountain pens and has for its object the production of a pen of this type which shall be free from certain objections heretofore existing and shall have certain advantages which shall be hereinafter pointed out.

As well known, a fountain pen, l'1ke a thermometer, is sensitive to changes in temperature, and unless the pen barrel is kept full of ink which is not practical, the expansion of the air in the pen due to any use in the temperature will force some of the ink out of the pen, producing what is commonly called flooding or leaking. I provide against this condition by constructing a small supplemental reservoir in the pen feed, and connected passages and channels beneath the pen so that a certain amount of ink can be received and retained without overflowing, and at the same time the pen will be ready to write, as this ink will not fiow back into the barrel. this special construction, an incident in the general construction of my pen is to place 1t under better control of the user so he can readily detect the fact that it is flowing too freely and be enabled to remove the surplus ink from the pen.

Another disadvantage heretofore encountered has been a lack of perfect alinement of the pen with the feed parts and the barrel, due to accident, wear, or imperfect adjustment. As ordinarily constructed, if the pen should spring away at the point or nlb, the feed would cease until readjustment is made. Corollary t0 the alinement proposition, is that of keeping the pen from contact or near approach with or to any projection on the holder or barrel, to which the ink could adhere and be drawn away from the point of the pen by capillary attraction. I meet both these requirements and obviate the objection on the score of alinement, by fastening the middle of the pen tothe feed, instead of the reed or stem portion. This enables me also to attain an additional advantage by forming the pen with two points In addition to v or nibs, one at each end. Being secured at an intermediate or middle point the pen can be reversed by slight manipulation of the fastening means, and moreover one end is balanced against the other in its pressure against the feed parts, so that perfect contact at all times and perfect alinement are assured. The two points may be the same or difierent.

An additional feature of invention consists of a combination filling device and clip, which without alteration is used to fill the pen, whether the latter is provided or not with a rubber sack, by simple manipulation. When not in use as a filler, the device is carried on the side of the cap and acts as an ordinary clip to hold the pen in the pocket.

My invention is illustrated in the accompanying drawings in which- Figure 1 is a longitudinal sectional view of a pen complete, with cap and filler.

Fig. 2 is a plan view of the cap of Fig. 1 to show the combined clip and filler.

Fig. 3 is a plan view of a cap and clip of modified form.

Fig. 4 is a sideview of the clip rod removed.

Fig. 5 is a transverse section on the line 5 5 of Fig. 1.

Referring to Figs. 1 and 2, 1 is the barrel of the pen, 2 is the feed plug, which is shoul dered and may be threaded at 3 to fit the barrel. 4 is an auxiliaryreservoir formed in the feed plug, 5 is an opening from said reservoir through the upper part of the plug, and 6 is adepression in the upper face of the plug, which underlies the pen 7 and is kept filled with ink from the small reservoir 4: by the force of gravity and capillary attraction. The pen 7 is centrally pivoted at 8 to the plug 2, and by reason of its curvature as shown in Fig. 7, which fits the curvature of the plug 2, it is held in perfect alinement at all times. In the middle of the reservoir 4 I provide a leader or feed tube 9, containing a central passage which communicates with the small tubular passage 10 through the main body ofthe plug 2. The flow of ink from the barrel is therefore through the plug and through the tube 9 to its end 11, thence into the reservoir or directly out through the opening 5 to the pen.

The pen 7 is double ended, that is to say it is made with two points, each finished in the usual manner, and tipped with iridium if the pen be of gold as it usually is. Apart and the other a stub. I believe I am the first to thus provide a fountain pen with interchangeable points, forming a part of the pen itself and not requiring the removal or replacement of the pen. I shall therefore claim the same as part of my invention. Its

practical value will be understood when it is,

considered that many persons, especially traveling men and bookkeeper-s are compelled to carry at least two pens, since it is impossible properly to make book entries of accounts with a pen adapted for correspondence, or vice versa.

In Fig. 1 the barrel is shown provided with a rubber sack or ink holder 12. This may be dispensed with, without altering the invention.

13 is the cap, which fits over one end of the barrel as shown in Figs. 1 and 2. A double band 14 with a bridge portion 15 is secured around the cap, and carries on one side a spring clip 16, and is provided with ears 17 on opposite sides of one of the bands, and a bail 18 with a central collar 19, in which slides the clip rod 20, which is ordi narily held fast in the spring clip 16, and requires considerable force to be disengaged therefrom. The normal position of the clip rod 20 is shown in Figs. 1 and 2. When it is desired to use the rod as a filler, however, outward pressure is exerted on the end 20 until it springs free of the clip 16 and turns the bail 18 in the ears 17 until the parts occupy the position shown in dotted lines in Fig. 2. The rod can he slid through the collar 19 and into an opening 21 formed in the end of the cap, to engage the plunger 22, made of leather, rubber, or other suitable material, which is fitted to work in the bore of the cap, like the piston or plunger of a pump.

For the purpose of permitting ready filling, the barrel 1 has an air hole 23 in its upper end normally closed by the screw plug 24.

The operation of the pen thus described is as follows:

In filling, the cap 13 is removed from the pen end of the barrel, and is placed upon the opposite end after first loosening the screw 24 by backingit off two or three turns. The clip rod 20 is lifted clear of the clip 16, swung around in the bail until it can be pushed through the opening 21 andscrewed in the plunger 22. The pen is then dipped into an ink container, and the'rod is pushed in so as to force the plunger down through the length of the cap, thereby forcing air through the passage 23 and collapsing the ink bag 12, while the pen remains immersed in the ink. The cap 13 is then removed en tirely from the barrel 1, and in a few seconds the sack 12 will be filled by atmospheric pressure and capillary attraction, assisted by the resilience of the bag. The rod 20 is then unscrewed from the plunger 22 after pulling the plunger up to the inner end of'the cap, and the bail 18 is re-turned until the rod again engages the spring holder 16, when it will be in position as shown in Fig. 1 to serve as a holding clip adapted to engage the fiap of a pocket.

When using the filler with a pen barrel having no ink sack, the plunger is first pushed all the way down in the cap, the cap is placed on the upper end of the barrel, the pen end is inserted in a vessel of ink, and the plunger is withdrawn, thereby creating a partlal vacuum in the barrel, which causes the ink to rise therein by atmospheric pressure. The cap is then removed and the screw 24 is turned down to close the opening 23,

when the pen is ready for use.

The form of clip shown in Figs. 3 and 4 is somewhat different from that in Fig. 2, but is based on the same principle of using the clip rod 20 for a filler. The band 29 is solid, and carries two sleeves 31 and 32 into which the rod slides, a guide ring 33, and a small spring latch 34, adapted to engage a notch 30 in the rod when the latter is in position (see Fig. 4). When in use with the filler, the rod functions the same as before described.

It will-be observed that in regard to the auxiliary reservoir 4 of Fig. 1, I have achieved a very desirable object, because when the pen is set vertically in the pocket, the ink will drain out of the tube and tend to produce a partial vacuum in the chamher or receptacle for overflow ink. The slightest expansion due to heat will therefore be relieved without pressure on the ink in the barrel, and flooding thereby becomes impossible.

I wish it distinctly understood that many changes and modifications in matters ,of detail are contemplated by me as a part of this invention, and can be made without departing from the scope thereof, as defined in the appended claims.

Having thus describedmy invention what I claim and desire to secure by Letters Patent is:
