' FOUNTAIN-PEN.

Specification of Letters Patent. 7 Patented Dec, 10, 1912.

Application filed May 22, 1912. Serial No. 699,044.-

The object of the invent-ion is to provide a duplex fountain pen which shall be simplev in structure, easy of operation and especially handy for traveling men and others who desire to use different colored inks.

In the embodiment of our invention we provide a tubular barrel having a plurality of reservoirs longitudinally slidable therein.

Each reservoir carries on its lower-end a pen point and feeder and the reservoirs are so connected that when one pen point is being used the other will be disposed with the barrel or casing.

The invention consists in certain novel constructions and arrangement of parts, as we shall hereinafter fully describe and claim.

For a complete understanding ofour invention reference is to be had to the following description and accompanying drawing, in which Figure l is a side elevation of our improved pen. Fig. 2 is a longitudinal sectional view, partly in elevation. Fig. 3 is a perspective View of the division plate. Fig. 1 is a transverse sectional view on line 4-4 of Fig. 2. Fig. 5 is a-longitudinal sectional view showing a modified form of our invention. Fig. 6 is a longitudinal sectional view, partly in elevation, showing another modification.

Referring more particularly to the drawing by numerals, 1 designates the tubular barrel or casing, the inner wall of which is provided with the oppositely disposed longitudinal grooves 2, which receive the edges of the division plate 3 and hold the same in position. The plate divides the barresiding at Logan, in the 6 of each reservoir is detachable, being screwed to the main portion, and is provided with the pen point 7 and feeder 8 of the usual construction. The reservoirs may be filled through the top after removing the threaded plugs 9.

10 is a small hole for the pur ose of admitting air as t e ink is consumed When one reservoir is being used its pen point extends entirely without the casing and the other reservoir and pen point are housed within the casing. Removable caps 11 close the ends of the said casing.

The upper end of the partition plate 3 is enlarged as shown at 12 and formed with a transverse slot 13. A grooved roller 14- is held within this slot by the screw 15 which passes through the enlargement 12 at right angles to the slot 13 and has its head counter-sunk and its end threaded, into the barrel 1. chain 16 connected at its ends by swivels '17 .to the plugs 9 passes over the roller 14, the roller being spaced from the top of the slot 13. v

The upper end of the barrel 1 is cut away on opposite sides of the division plate 3' to form the end opening recess 18' the purpose of whicliwill be hereinafter explained.

A small flat metal spring 19 extends through a slot 20 in the lower end of the partition plate 3 and has its end portions 20 bent upwardly on oppositesidesof theplate 3 and secured thereto. The spring is for the purpose of holding reservoir 4 or 5 immovable when in use and is so positioned that simultaneous engagement with both reservoirs is impossible. As shown in Fig. '2 the reservoirs 4c and 5 are of such a size that they may be easily moved past the ends 20' of the metal spring 19, but if desired said ends may be sunk in the partition,

3 and made to lie flush with the same, in which case the reservoirs may be made of such size as to fit. snugly within the barrel.

' said reservoir is forced, by pressing in the upper exposed end of the same, longitudinally of the barrel toward the lower end thereof; This sliding movement brings the reservoir into frictional engagement with the spring19'aud' automatically draws the.

reservoir 5 to the top of the casing 1 and away from engagement with said spring.

The chain 16 running over thepulley 14 furnishes the means of raising one reservoir when the other is lowered.

From the foregoing description in connection with the accompanying drawing it will be seen thatwe have provided 'a duplex fountain pen of simple construction, compact form andrnovel arrangement of parts.

It is to be understood that our invention may be constructed of any suitable material and that slight modifications may bemade site sides of the division plate and having a central portion working in a slot in the nately engage the reservoirs.

In testimony whereof We hereunto affix our signatures in the presence of two witnesses.
