WILLIAM F. ULLRICH, 0F WARREN, PENNSYLVANIA.

FOUNTAIN-PEN.

Specification of Letters Patent.

Patented Mar. 9, 1915.

Application filed February 5, 1914. Serial N o. 816,776.

T0 all whom 'it may concern.'

Be it known that I, VILLIAM F. ULLRICH, a citizen of the United States, residing at Warrenl inthe county of Warren and State of Pennsylvania, have invented certain new and useful Improvements in Fountain-Pens; and I do` declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to whichjit appertains to make and use the same.

Myinvention relates' primarily to fountain pens but more especially to that class of the latter which employs two pens in conjunction with a single barrel.

A One object of my invention is to provide a duplex fountain pen of this character, having two reservoirs adapted to contain dilferent colored inks, and possessing facilities whereby each pen point 'can be separately supplied, and used as conveniently as a pen having but a single pen point.

Another object of the same is to construct a fountain pen having al single reservoir but provided with two pen points of different qualities either of which can be used when desired.

Another object of my invention is to provide a head adapted to be detachably enga ged with the barrel and having means for forming an ink-tight oint when it is in engaged position.

With these and other objects in View, my invention consists of certain novel details of construction and combinatiom;` and arrangement of parts which will be more particulai-ly pointed out and claimed.`

In the accompanying drawings in which similar' parts are designated by |corresponding numerals: Figure'l is a side elevation, partly in section of my improved fountain pen; Fig. '2 is a similar view of the pen supporting head, the sleeve being illustrated in a disconnected position; Fig. 3 is a transverse longitudinal section'illustrating my improved pen in assembled condition; Fig. 4 is a transverse vertical section taken on the line 4 4 of Fig. 3; Fig. 5 is a similar view taken on the line 5-5 of Fig. 3; and Fig. 6 is an end elevation of my improved pen supporting head illustrating the yieldable hemispherical sections formed on the latter.

In its present embodiment my invention comprises a barrel 1,-slightly tapered at the one end and externally threaded as at 2. A

transversely disposed longitudinally extend# ing partition 3 formed in the barrel 1, di vides the latter into two separate chambers 4 and 5 which actas reservoirs for the dif'- ferent colored inks.

.'Ielescopically` engaged with the one endl of barrel 1, is'a pen holding head 6, cylindrical in conformation and provided with two adjacently disposed longitudinal channels 7 and in the latter are suitably disposed two ink feeders 8. Pen points 9 are mounted back to back with their upper portion disposed with said channel in operative relation with said'feeders. In this connection it will be noted that one of the Walls of channels 7 are` convexedly' shaped so as to substantially conform to the shape of the pen. Extending around thehead 6 nearthe inner end thereof is an annular shoulder 10 the purpose of which will be" hereinafter explained.

To individually connect each pen with one of the reservoirs so as to avoid any possibility of the ink in one reservoir intermingling with that of the other as it flows to thepen, or likelihood of the ink reaching the exterior of the pen to stain the fingers, I slightly taper the inner end of the head 6 and form the latter With a transverse slot l1, which it will be seen divides said end into two hemispherical shaped extensions or sections 12 and 12, each containing one of the channels 7 carrying the feeders 8 andpen points 9. By this construction and arrangement when the inner end of head 6 is telescoped into the barrel, one of said sections or extensions will project into each reservoir, and owing to the tapered formation of the inner end of the barrel l and the head 6, the sections will be vthreaded end of barrel 1, forming a simple connection for retaining the head in proper position. Openings 15 are formed in the outer end of barrel 1 to permit the latter to be readily cleaned when necessary, said opening being closed by the threaded plugs-1G. A cap 17 is provided for the proi' tection of the pen points'9.

rIhus it will be seen that I have provided a duplex pen, which is simple, easy to construct and one in which it is absolutely impossible for the two inks in the reservoirs to intermingle owing to illy-unique method of connecting the head and barrel.

From the foregoing description taken in connection with the accompanying drawings, theV construction and operation of the invention will be readily understood without requiring a more extended explanation.`

Various changes in the form, proportion and the minor details of construction may be resorted to Without departing from the principle or sacricing any of the advantages of the claimed invention.

What I claim as new is A fountain pen comprising a barrel closed at one end and having its inner surface con tiguous to its open end flared outwardly, a longitudinally extending partition disposed therein, said partition forming reservoirs, a slotted cylindrical head telescoping into said barrel, said head having oppositely disposed longitudinally extending channels therein, the inner end of said head being slightly tapered and transversely slotted to receive one end of said partition and to form yieldable sections, each having an opening therein whereby when the inner end of said head'is telescopically engaged with the outwardly flared end of the barrel/and,

be compressed so as to be brought into frictional engagement with the opposite faces of said partition, thereby forming an ink-tight joint, feeders disposed in said longitudinally extending channels, pen points disposed in the latter in operative relation with said feeders, and a vsleeve threaded on said barrel and inclosing said head, there being engaging shoulders in said sleeve and on said head, whereby the latter is securely-fastened to said barrel.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
