FOUNTAIN-PEN.

SPECIFICATION forming part of Letters PatentNo. 407,999; dated July 30, 1889. Application iilod October 18, 1888. Serial No. 288,462. (No model.)

T all Ywlw/rz, it may concern:

lle it known that-.1, DnwIr'r C. DnMARns'r, a citizen of the United States, residing at Denver, in the county of Arapahoe and State of Colorado, have invented a new and useful Improvement in I1`ountainlens, of which th following is a specification.

In improving the fountain pen I yhave ainied to produce an efficient and simple construction whereby the ink may flow freely from the -fountain to the l pen Without dropping. A 1

The specific points of novelty will .be designated in lthe claims concluding this speeilication.

The following is a descriptionl of the aecoinpanying drawings,'in which is illustrateda fountain-pen having applied thereto my several improvements in effective forni.

Figure l is a longitudinal section of the pen. Flg. 2 1s a longitudinal seetion of the pen-holding plug and a portion of its hollow holder. Fig. l is a top view of the same.- Fig. 5 is a view looking at the inner end. Fig. 6 is 'a cross-section on the line a of Fig.- Fig; 7

is the feeder. Fig. S is thepen, and- Fig. 9 shows the under side of the plug with the pen removed.

The handle or the holder is made hollow in the ordinary Way to contain a supply of ink and to receive at one end' the pen-holder or plug.

The pen-holder is a sho-t plug 1 of' semicylindrical forni in cross-section for a portion of its length. Its front end is cylindrical at 2, and from its upper side a tongue3 projects opens at the front end of the plug, being also open at the inner end of the plug, and forms both the passage for the ini; to the penandl an air-vent to the ink-reservoir. This front opening in the plugv is about seven sixtyfourths of an inch in'diametelgand is divided Fig. 3 is a side view of the same.

The cylindrical part '2;

at its outer end so as to form an upper and a lower opening, such division being made by the end of the pen (z, so that the upper opening 5 leads out over the pen, asin Fig. 6, for the How of the ink, and the lower opening 6 leads out under the pen for the airvent. Thispassage-dividing function of the pen is `made by placing the inner end of the pen against the outer end of the plug across said opening, so as to divide the latter about equally, and for this purpose I provide a pen having a bifnrcated shank so as to form two prongs 7, andbetween theinthe dividing-edge 8, which crosses the opening. The plug has a horizontal slot 9, formed in each side, and into them thel pen-prongs 7 are inserted to secure the pen to the plug. `I prefer, howsecured with its edge S'crossing the opening A5 6 about one thirty-second of an ineh from the top' ofthe opening, so as to leave a small How-passage 5 for the ink and a larger airvent 6 below i-t. v

The ink-feeder consists of a smallstem 10, preferably of a thin fiat piece of rubber placed against the under side of the plug tongue of less width than the latter, and eX tending to near its point overthe back of the pen, so as to leave a sidepassage 1]. between the latter and the under side'of the plugtongue on eaeh side of the feeder, as seen in Fig. 6. Both of these side passages open over the nibs ofthe pen and into the-plug-opening 5, so as to cause the ink to flow out of the latter. in two streams on each side of the feeder to the point of the pen To prevent the ink from flowing or dropping out of the air-vent the ink-feeder. is bent at its inner end 12, so as to cross the air-vent at right angies to the dividing edge of the pen, as seen in Fig. 5, and is secured in a hole 13 in the bottoni of the central groove 4 in the plug just back of .the opening 'in the cylindrical end of the plugs J his function of the feeder IOO ' Vthe feeder' over to the'pen-poin supply the pen'with inkandto prevent dropf ping. This cofoperation is eiiected bythein! nerv end 1'2 of the feeder, `which crosses -alike the outflow-passage 5 for the ink andtheinflow-passage 6 for the air'at the fronte'nd of the plug, and the feedingof theink is from the open side of the plug directto the pen, ont'under the plug-tongue"along each side of It will be seen'that the pen-plug is inserted enti-rely within the handle-reservoir, and that the pen and plug-tongue only project from the handle. "This,construction--givesfa simple Away of obtaining theadvantag' of using a plug cutaway on one side, se aste leave an 1 end joint-forming vringpart 2,' tapering inf ink will,v flow lby capillary 'attraction` to. the

die to close its reservoir and `bring thelatter down close to the outer end of the pen-plug. f It is from this open-plug part that the feeder takes the ink 'to the spaces between the'plugtongue and the pen', along which spaces the point of the pen'.

The selnicircula'rpart l of the pen-plugins closely within the open end of the handle; but the tapering joint-termin g ring .part 2 is about one-sixteenth of an inch, so as, in connecti'on with the cutaway part of the plug, to bring' the reservoir open as near thepoint of thepen a'spossible, and just at the opening in the plug through which the "ink passes from the reservoir. 1

The handle and pen-plug are preferably made of hard rubber, and thelhandle is provided with the usual cap 14,-'adapted to be iitted on the closed end of the 'handle when the pen is being used and to be fitted over the pen-plug when the pen is not being used.

The ink-feeder lies upon the pen and the tongue lies upon the feeder, and the tongue tapers both in thickness and in width to the point, while thefeedei tapersin thickness to the point, so that the tongue and the feeder will yield at their points to pressure applied.

. to the pen and thereby insure the free ioW of The plug is held in place in the lower open end ofthe reservoir by its beveled ring part 2v being pressed snugly therein to its seat in the flaring end, so that Whileit is tightly held in place it is easily removed for cleaning and for filling the reservoir, or for changing the pen. This construction also avoids the expense o f a screw-plug. The plug is adapted for 'the use of a gold pen. -The tongue is made thin at its point, so as to yield against the pressure of the pen, and the feeding-stein Ais beveled at its point on thev under side tol facilitate the icedivngof the ink. to the point of the'pen and leave the lat-ter freeto yield 'under pressure in writing. While the plug is shown as being-adapted for use with apen having prongs atlits rear end', yet the inkfeeding device is not dependen-t upon the particular form of the penshown.l

' An important featureof my `iinpref/erneut is the .relation of the parts which 'comprise the inkfeeder, in which the central opening of the plug is crossedat the outflow end of the '.pen, the ink. feeding stem .extending Se from the over-How overl the back of thepen,

.andlthe'tongue extending from said opening overthe feeding-stem and'having a width and alength greater than that-of the said. feedingsteun. Y p p l claim as' my improvement- .1.
