FOUNTAIN PEN.

The present invention relates to a fountain pen and has for its object to provide a device of this character which embodies novel features of construction whereby the flow of ink to the pen point is under control and caneasily be increased or decreased while the pen in use and without any interruption to the'writing operation.

The invention further contemplates the provision of a pen of this character which is simple an d inexpensive in its construction, which can be used without soiling the fingers, and which can be easily manipulated while in use to increase or decrease the flow of .ink to the pen point, as may be desired.

wWhile one particular embodiment of the invention will be shown and described in detail for illustrative purposi-is, it will. be understood that many modifications and changes can be made in the details of construction without departing from the spirit and scope of the invention.

For a full understanding of the invention reference is to be had to the follow` ing description and accompanying drawings inv which:

Fig. l, is an enlarged longitudinal seetional view through the ink feeding end of the fountain pen. f

Fig. 2, is a side elevation of one end of the fountain pen, looking1 downwardly upon the slide which controls the feeding of the inl/r` t0 the pen point.

Fig. 3, is a detail view of the wire stem which projects from the valve for controlling the flow of inlr.

Correspoinling and like parts are referred to in the follow' description and indicated on all of the views of the drawings by like reference characters.

Referring to the drawings, the numeral l designates the barrel of the lfountain pen which forms a reservoir to receive a supply of ink and is closed at its rear end by means of a cap. This cap can be readily removed at any time when it is desired to lill the reservoir with ink. y

The other end of the tubular barrel l has a plug 4 fitted therein to close the same. This plug is formed with a suitable opening or seat to receivethe rear end of the pen point 5 and has anl inlr feeding passage 6 therein which extends under the forward end of the pen point and communicates at 5, 1925. serial no. 67,049.

its rearend with a chamber 4a which `is in'med in the rear endv of the plu The forward end of the ink fee ing passage G extends to a point slightly beyond the eye 7 of the pen point and the rear end ofthe inlr feeding passage is flared to provide avalve seat 8. A tapered valve 9 is movable toward and away from the said valve seat to regulate the flow of ink through the passage 6.

A wire stem 10 which is connected to the valve 9 extends forwardly through the ink feeding passage 6 and terminates in a perforated head l0 which is adapted to receive a lateral arm` ll projecting through the eye 7 of the pen point. This lateral arm l1 is carried by a stein l2 projecting from the end of a slide 13 which is mounted in a channel l/lformed in the barrel l and extending longitudinally thereof. The slide preferably has the outer surface thereof roughened so "that it can be readily engaged. by one of the lingers of the hand to move the same longitudinally of the barrel thereby moving the valve 9 toward or away from the valve seat and decreasing or increasing the flow of ink, 30

`as maybe desired. The end of the barrel 1 formed with an annular enlargement or rib 15 which tends to prevent the fingers from being moved downwardly over the end of the barrel and smeared with inlr by bei ng brought into engagement with the pen point. This annular rib or enlargement is formed with a suitable guide opening through which the member 12 passes.

n When the pen is in use the ink will flow frein the interior of the barrel through the feed passage 6 to the pen point in the usual manner7 and by moving the valve the feed i ing of the ink canbe controlled by the operator .so that an increased or decreased amount of ink will be fed to the pen point, as may be desired. When the pen is in use one ol' the fingers of the hand will engage the roughened surface of the slide 13, and the slide can be manipulated to move the valve and control the flow of ink to the pen point in the desired manner.

Having thus described my invention what l claim new and desire to secure by Letters Patent is:

l. A fountain pen including a barrel, a pen point formed `with an eye, ink feeding means for supplying ink to the pen point, a

valve controlling the flow of ink through the ink feeding means, a slide mounted upon l theexterior of the barrel, and means con- Ynecting the slide to the valve and including an. element Aextending through the eye of i 'the pen point. Y

2. A fountain pen including a barrel, a

pen point formed 'with an eye, ink feeding means for supplying ink to the pen point, a valve controlling th'eflow of ink through therinl feeding means, a Wire connected to the valve and terminating in a 'lateral arm projectingthrough the eye of the pen point, and ay slide inounted upon the exterior of thev barrel randy connected to the arm.

'3. 'A fountain pen 'including a barrel, a'

f 'pen point formedwith an eye, ink feeding means for Carrying ink from the barrel to theV pen point', a valvecontrolling the flow of ink, a stem `projecting from the valve and having a perforated heath-a .slide lnounted upon the barrel, and an arm carried b f the slide and projecting through the eye of the pen point into engagement with the perforated head of the valve stein.

4. A fountain pen including a. barrel, a plug closing one end of the barrel and formed With a pen point receiving seat and an ink feeding passage, a pen point foi-ined with an eye and fitted in the seat of the plug, a Valve for controlling the flow of ink through the passage, a stem projecting from the valve and terminating in a perforated head, a slide mounted upon the barrel, and an arm carried by the slide and projecting through the eye of the pen point into engagement with the perforated head of the Valve stein to provide an operative connertion between the slide and the valve.

In testimony whereof I ailix my signature.

JOHN A. KAYE.
