FOUNTAIN-PEN.

Specification of Letters Patent.

Patented June 9, 1908.

Application filed January 16, 190B. Serial No. 411,068.

Fountain-Pens, of which the following is a clear, full, and exact description.

The object of this invention is to provide Within one holder` of a fountain pen at least two individual pen points, together with reservoirs adapted to contain 1f desired more than one kind of ink.

In carrying out this invention, I make use of a simple tubular barrel having slotted openings in the side thereof, and within the barrel longitudinally sliding therein, I locate a plurality of ink reservoirs; preferably each in the shape of half'a cylinder in cross section. I'Vithin the single tubular case or holder I provide a suitable gearing connecting the individual reservoirs so that upon the projection of one reservoir the other will necessarily be withdrawn from the open end of the tubular receptacle.

I further provide suitable valve means to prevent ink from [lowing in that pen which is at the time retracted in position. Such suitable valve meansis preferably a ball adapted to close the orifice through the pen stock; and I further provide tracks having sharp apices on which the ball may travel without sticking thereto through guminy deposits. I further provide a cover for the holder, which will engage projecting studs on the independent reservoirs, and by the mere insertion of the cap in place both pens will be likewise withdrawn an equal distance into the receptacle. j i

The scope of my invention will be set forth in the claims.

lIn the accompanying drawings Figure 1 is a front elevation of my improved pen holder with the cap in section. Fig. 2 is a transverse section of the holder proper with one of the independent reservoirs shown partly in. section. Fig, 3 is a section on line 3 3 Fig. 2 with. the links removed. Fig. 4 is a section on line 4--4 Fig. 5. Fig. 5 is a detail of the valve cage provided with the tracks and is shown partly in section, on line 55, Fig. 4. Fig. 6 is a section of the valve cage on line 6 6 Fig. 4.' Fig. 7 is a section showing the gearing taken on line X X Fig. 1.

In carrying out my invention I provide a tubular holder 1, having slotted openings on opposite sides i2-3, and having a threaded that t rigid upon the projection of their reservoir lower end 4., which is secured to the main body of the holder as at 5 by screw threads. Each longitudinally slid able reservoir 5 and o is provided with an eye 7 at its upper end, to which is connected a link 8 in turn pivoted to a link 9, which is secured to a pivot point 1() on a wheel 11, journaled in bearings 12 in the u per end of the tubular case or holder 1. nee plates 13 are secured to the links 9 so e linksS and 9 may be maintained member, and thus prevent the accidental retraction of the same. Each reservoir carries a removable pen stock 14, which maybe fitted thereto in the ordinary way.

I prefer to form around the lower edge of the pen stock grooves or notches 15 for engagement with ones fingers to aid in removing the pen stock when it is necessary. The )en stock carries theordinary pen 1F, and eeder 17, which is fed with ink through an opening 18 through the pen stock. The

opening 18 is at the upper end surrounded by a collar like projection 19, so that a ball 2() carried within the valve cage will never touch the surface of the pen stock except when taking a, position over the orifice 18.

The cage' which surrounds the ball is in reality a .succession of tracks, on which the ball may run bearing against their sharp edged apices; thus doing away with an tendency which the ball may have to stic to the surface due to ink coatings thereon.

The cage is made open at the top, though the opening is of a less width than the ball 20, and it is formed with two downwardly rejecting tracks 21, which are occasioned hy the turned over edges of the side plates 22 of the cage. The ends of the cage to the right may be similarly turned-in 'to form tracks 23 while the 'right hand end of the cage I prefer to provide with a single track At the-bottom of the cage and to the right I provide a small track 2.5. It will be seen that the ball, while it may touch the sides 22 of the cage at some times, can never rreally rest its weight when in motion on stock, and in the modification shown in these drawings the cage may be made of one single stamping, although it will readily be understood that l do not limit myself to so constructing it.

Through the slots 2 and 3 of the casing 1, l project pins 26%27. One of these pins .l preferal'ily make black and the other one red, and l fasten them in place in their respective reservoirs by threading their ends, so that they may be removed if desired to permit the filling of the pen through the oriiice left by their removal, the air within the reservoirs escaping through the pen stock. When it is desired 'to clean they pen, the extension 4 is removed and the pens placed in the position of Fig. 2, when the pen stock 14 may be taken from its reservoir, and the reservoir cleaned.

The cap 2S is notched preferably at 29 on opposite sides of the same, so that when si into place the notches 29 will en rage with the pins 26e-27 respectively, an retract the extended pen so that it can not contact with the material of the cap and become damaged.

' From the position of the valve 20 in Figs. 4 and 5 it will be seen that when a pen is A ,held so as to write with the )rejected pen point the valve will have rolle( on its tracks to the right in Fig. 5, thus engaging the oritice, but when the pen is being used in the osition shown in Fig. 2 the valve Z0 of the eft hand pen stock will roll to the left land cover the orifice, thus )reventing feed from any pen, but the one w iich is being used by the writer at that time. In operation one would remove the cap and push forward that pen which controls the ink desired, whereupon that reservoir would pull its links down, rotate wheel 11, retract the links of the other reservoir, and lift the other reservoir into -its retracted position.

I claim as my invention:
