To all whom it may concern.-

Be it known that I, Fnnnsnrorc WILLIAM BENDER, a citizen of the United States, residing at I-Iobolren, in the county of Hudson and State of New Jersey, have invented new and useful Improvements in Fountain-Pens, of

The object of m invention is'to provide a device by means 0 which. fountain-pens ma be filled by means of suction; I aoeom lis this by .two devices, but each of Whic involves the same rinciples, as will more particularly hereina ter appear;

My invention rel ates to a reservoir for holding a tube made of rubber or other suitable material, the upper end of the reservoir being furnished with a cap through an opening in which a cored rod is inserted, attached to the lower end of which is an aplertured plunger corresponding in she a Wit the interior of the reservoir, and w 'ch cored piston rod slides up and down through a corresponding core in the cap, and the upper end of the pietonrod is equipped with a knob also supplied with a corresponding'core.

My invention also relates to a fiercible tube,

bein slip ed over a collar at the end of the core fee to which the pen is attached. The core in the piston-rod, plunger, and cap may be eliminated and an aperture in the reservoir substituted, and by opening and closing ose as the core in piston-rod, plunger, and ob attain the same result, but reduce cost of manufacture, This form of construction involves the same principle; but instead of a tache I construct the piston-r0 an plungel in solid form and admitor exclude the air for the urpose of bring' about the suction for fil g the tube in t e reservoir bycovering or, uncovering the aperture in the reservoir as is required for that urpose.

Preliminary to'feeding the to e in the reservoir the aperture is closed with the thumb or convenient finger, and the PiSllOIlfI'Od is then'pushed downward as far as the knob on the upper end of the piston-rod will allow. The p anger will cause 'theair in the reservoir to contract, in doing which it will also conor finger is removed from theaperture the air is allowedto escape fromthetube, thuswith pen in place.

plunger and to the upper end ofthe pen attached to the feed B.

causing the flexible tube in the reservoir to resume its normal shape, thereby bringing about the suction and causing the ink or. other liquid to pass into the tube ready for use and in like manner and with similarparts, as hereinafter more fully set forth in the other construction of my filling device. I attain these objects by means of the mechanism illustrated in. the accompanying drawings, in

Figure 1 is a side view of the fountain-pen Witl the piston-rod withdrawn preliminary to filling with all the several parts assembled. Fig. 2 is a side view of the fountain-pen with the piston-rod pushed down and the tube contracted preliminary to filling with all the several parts assembled. Fig. 3 is a view of the flexible tube attached to the" cored feed Fig. 4 is a cross-section showing the cored cap to'he inserted into the upper end of the reservoir. Fig. 5 is the] iston rod and plunger attached.- Fig. 6 1s a cross-section showin cored piston-rod and a srtured plunger. '2' is a cross-section o the cored feed with pen attached. Fig. 8 is a crosssection showing solid piston-rod and plunger with aperture in reservoir.

The reservoir A is closed air-tight at the ulpper end by inserting the projection a. into t c reservoir until the under surfaceof the collar b is flush with the u per end 0 of the reservoir. The iston-rod is inserted into and through the ore d to move freely up and down. Attached to the piston-rod is the p rod is fastened the kno 1, with a corres ending core If The piston-rod is furnishc with a core it, corresponding with core I, and a erture m. The a rturem is an opening in the pc er w ch corresponds with the core S it t e lower end'of reservoir A is insorted the feed B, so that the lower end of the reservoir A is flush 'withthe collanb', thus closing the reservoir air tight. The tube 0, however,fis first slipped over the projection c" c is asleeveintegral with'nozsle B and surrounding the forward end of the tube a, said sleevejorrning a seat for the reservoir A. The feed Bis provided with a core oflahro h which the ink flows from the tube G into t e To fill the pen, the folk) procedure is required,' viz: The piston-rod {is drawn upwardly and outwardly until the plunger fis' flush with the lower end of the projection a I as shown in Fig. 1. The core I isthen close with the finger, thus shutting of? the air from r a. erture m and out at the core 3, allowing t e tube C to resume normal shape, in (loin; which the ink or other fluid is sucked up through the core 0 into the tube where it remains ready for use.

What I claim as my ii'ivention, and'desire to secure by Letters Patent,

1. In a fountain-pen, a reservoir, 21 pen-set tion, carried at the forward end of said reser- Voir, an elastic tube, shorter than said reser- Voir and closed at the rear end, mounted on said pen-section, and lying within said reservoir, a piston mounted in said reservoir at the rear of said tube, an operating-rod carried by the said piston, passing through the rear end of said reservoir, and means for admitting the air between said tube and piston at any position of the piston.

J. in a iountain-pen, a reservoir, a pen-serftion carried at the forward end of said reservoir, an elastic tube shorter than said reservoir, and ciosed at the rear end, mounted on said pen-section, and lying within said reservoir, a piston mounted in said reservoir at the rear end of said tube, and an operatingrod, carried by said piston, passing'through the rear end of said reservoir, said stem and piston having a hollow core for admitting air.

In Witness whereof I have signed my name to this specification in the presence of two subscribing witnesses.
