TWO-COLORED FOUNTAIN-PEN.

Specification of Letters Patent.

Patented Mar. 25, 1919.

Application filed March 23, 1918. Serial No.` 224,154.

To all whom 'it may concern:

Be it known that I, EDMUND GEssMANN, a subject of the Emperor of Austria, residing at Union Hill, county yof Hudson, and State of New Jersey, have invented certain new and useful Improvements in Two- Colored Fountain-Pens, of which the following is a specification.

This invention relates to improvements in pens and particularly to ink filled types adapted to be carried in the pocket, known as fountain pens.

The principal object of the invention is to provide means whereby two pen points may be used in connection with a single holder, each of the pens havino' an independent supply of ink which mayibe of different colors.

Another obj ect is to provide means whereby one of the pens may be permanently extended, as likely to be used more than the other, whilethe other pen may be retracted into a recess, so as to offer no impediment to the use of the main or outwardly extendin pen. 4

hese and other like objects are attained by the novel construction and combination of parts hereinafter described and shown in the accompaanying drawing, formino` a material part of this disclosure, and in which Figure 1 is a side elevational view showing a pen made in accordance with the invention.

Fig. 2 is a longitudinal sectional view taken substantially through the center of the same on line 2-2 of Fig. 4.

Fig. 3 is an enlarged fragmentary longitw,l

dinal sectional view taken on line 3-3 of Fig. 2, and i Fig. 4 is a transverse sectional view, taken 'on line 4-4 of Fig. 3.

Like other instruments of similar character, the parts are made mainly of hard rubber, the pen nibs or points being of `gold or other preferred material. The main part or barrel 10 is cylindrical exteriorly and formed with two longitudinal recesses,respectively 11 and 12, in which are fitted separate caps 13 and 14. So as to retain the contents, and acting as filling inlets for the openings.

When the pens are not in use, a'cap 17 is the opposite end of the barrel, covering the plugs, when the pen is in operation. A spring securing means 18, is fixed upon the cap and holds the same when within a pocket. a

plu

also fitting I An extension 16 is formed to receive the sleeve or bushing 20, containing a plug 21, having a central passage 22, the plug being tapered at its outer end and fitted to receive the pen nib 23, and capillary feeder 24, by which ink is conducted from the longitudinal opening 22, and passage 25.

At the opposite side of the extension 16, is ,another sleeve 28, surrounding a plug 29, having a central longitudinal opening 30, the 29, being slidable within the sleeve, whi e the opening 30 is in alinement with the passage 32 formed in the inner end wall of the ink reservoir 12. The opposite end of the plug 29 has fitted to it a pen nib 33, and capillary feeder 34, similar to that previously described.

Formed Vthrough the extension 16, upon opposite sides are longitudinal slots 36, similar slots 28, and secured to the plug 29 are extendn spring arms 40, bent rearwardly at 41, an again turned outwardly at 42, the laterally protecting elements 40, operating in the slots 37, while the slots 36 formed in' the extension 16, through which they extend and are provided with operative heads 44.

The projectingelements 40, 41 and 42 are made of spring material and are formed with lshoulders 45 so that when the pen 33 lis in an extended4 position', the shoulders 45 engage in recesses 46 formed in the side walls of the slots 36, or when the en is retracted, engage in similar recesses ormed near the ends of the slots. 1

In operation, the two compartments 11 and 12 having been filled with ink and it is desired to use the pen 33, the extending knobs 44, are depressed, and at the same time moved forward toward the operative end of the implement until the shoulders 45 engage with the correspondingl recess, holding the pen point 33 extended.

AObviously when it is desired to make use of the main pen 23, the knobs 44 are depressed and moved toward the rear or opposite end of the barrel until the shoulders engage with the rear recesses at which time the pen nib 33 will be retracted within the extension of the implement so as not to inter' 37, extending through the sleevel the outer extensions 42 operate in fere with the free use of the pen point or i nib 23. Thus either of the pens maybe used conveying a different color or species of ink as may be desired and it is to be understood that the implement may be no larger than the operation is substantially identical there-` maintaining ink therein, a plug ixed in said' extension in alinement with one of said reservoirs, a pen point carried thereby, means for conducting ink from one of said reservoirs to said pen point, a second plug sliding in a sleeve within said extension, and havin a central longitudinal channel, said plug eing in alinementwith the other of said ink reservoirs, a pen point fixed therein, communicatin means between said ink reservoir and sai pen point through said plug, a guiding sleeve for said movable plug slots `formed in said guiding sleeve and through said extension longitudinally of said barrel, spring arms rigidlyrengaged in said movable plug extendlng outward through said slots, knobs formed upon the ends ol said spring arms whereby they may be actuated in said slots, recesses formed in the edges of said slot, and detents formed upon said spring arms adjacent to said knobs whereby said sliding plug may be held in an adjusted position at either end ofsaid slots.

In testimony whereof vI have affixed my signature. l. V
