PATENT oFFicE.

JOHN. M. BEADLES, 0F LOS ANGELES, CALIFORNIA.

FOUNTAIN PEN.

Application led February 15, 1923. Serial Nol 619,105.

To all whom t may concem:

Beit known that I, JOHN M. BnADLEs, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and vState of California, have invented new and useful Improvements in Fountain Pens, of which the following is a specification.

This invention relates to fountain pens and more-particularly to means for replenishing the exhausted pen.

It is an object of the present invention to provide a fountain pen including a flexible ink sack into which ink may be readily drawn by a siphonic action. Another ob# ject is to provide a sack filling device of extreme simplicity and few parts. Another object is to provide an ink sack having formed therewith and projecting from one end thereof a stud or lug adapted to be gripped by a means for twisting the sack, the stud or lug being an integral part of the sack.

Other objects and advantages will be made manifest in thel following specification ofan embodiment of the invention illustrated in the accompanying drawings, wherein Figure 1 is a side elevation of a fountain pen incorporating the present improvement.

Fig. 2 is a sectional view of the barrel of the pen an'd a side elevation of the sack twisting deviceI removed therefrom; the sack being shown in the barrel in side elevation.

Fig. 3 is a sectional view showing the sack and the twisting device` in assembled free relation in the barrel.

Fig. 4 is a longitudinal section showing the sack twisting device partially drawn out and showing the sack twisted thereby.

Fig. 5 is a clutch end view of the twisting device.

The invention is shown as embodying a flexible elastic sack or bag 2 which may be made of pliant rubber to be telescoped in a fountain pen barrel 3 having the usual spoon and pen elements as shown in Figure 1. One end of the ink sack 2 is shown as .provided with a shoulder 4 beyond which projects an axial stud 5 which is shown as solid to provide a body to be gripped by means by which the sack 2 may be twisted and thus collapsed as shown 'in Figure 4 to expel air.

The sack twisting means is shown as including a small knob or button, this having.

a roughened periphery which may have a diameter about equal to the diameter of the barrel 3. The knob has a threaded body portion 7 to screw into internal threads 8 in the barrel with such a degree of friction as to prevent looseness of the knob so that it will remain put in any desired position. The inner end of the knob 6 is shown as provided with a plurality of ygripping jaws or prongs 9 which may be formed by bifurcatiug the knob radially inwardly from its inner end. The gripping jaws in their'free position have diverging inclined faces 10 with slightly rounded shoulders 1l vso that'when the knob is applied tothe threaded'end of the barrel the gripping jaws 9 will be crowded inwardly or contracted so asv to pass in under. a shoulder 12 formed in the barrel 3y and` which has a' conical vbore or seat 13 expanding inwardlyl as to the end ofthe barrel.

Thus when the knob 6 is applied the prongs l posite end of the barrel 3 and the axial stud is only necessary to turn the knob 6 so that the 'stud to be rotated with the rotation of the knob 6. vSince the opposite end of the sack is connected toa fixed spoon it will be seen that the sackl will be helically twisted as shown 'in Figure 4l and the air will be expelled. It is desirable to prevent the entire removal of the knob 6 outwardly from the barrel while it is in engagement with the sack plug 5 and this limitation of movement is secured when the shoulder 4 of the sack moves into abutment, after a limited initial movement, with the wallforming the seat 13 which is of less diameter.v than lthe diameter of the shoulder 4.l

If desired the inner effective gripping faces of the jaws 9 may be toothed or roughened as at 9a to secure a firm hold of the sack plug or shank 5. Also, if desired, the shank may be provided with a slight peripheral groove or channel 5a the surface of which will be engaged by inwardly projecting contiguous faces of the jaws 9.

Obviously, as the sack is untwisted and expands the void will be filled by the inward flow of ink.

Preferably, the stud 5 is formed as an integral part of the rubber ink sack 2 and may beso treated as to give it a desired degree of hardness, as for instance by vulcanizing.

Further embodiments, modifications and variations may be resorted to within the spirit of the invention as here cl-aimed.

What is claimed is:

1. In a fountain pen, a barrel, an ink sack insertable into one yend of the barrel and having an integral reduced lug at one end,

t and a socket means mountedy at the opposite end of the barrel and adapted to grip said lug of the sack and to turn the same so as to twist the sack said socket means consistin of a rotary split clutch.

2. ign a fountain pen, a barrel, an ink sack insertable into one end of the barrel, and a socket means turnably mounted in the opposite end of the barrel and adapted to grip a port-ion of the sack and to turn the Same so as to twist the sack; the said sack and said means being normally wholly free of each other.

3, In a fountain pen, ya barrel, an ink sack insertable into one end of the barrel and having a lug at one end, and means mounted at the opposite end of the Abarrel and adapted to grip a portion of the sack and to turn the same so as to twist the sack, said means including contractive clutching jaws operative to contract on the lug part of the saclr.

4. In a fountain pen, a barrel having an `internal tapering seat, an ink sack insertable into one end of the barrel and having a lug `and means mounted in one end of the barrel having yieldable clutch prongs engaging said seat whereby upon a relative longitudinal movement of said elements as to the seat they will contract and engage said lug and turn the same with a turning movement of said means to twist the sack.

5. In a fountainv pen, a barrel having an internal "conical seat, an ink sack insertable into one end of the barrel and having a lu and a rotary socket mounted in one en of the barrel having yieldable clutch ele` ments engaging said seat whereby upon a relative longitudinal movement of said kelements as to the seat they will contract upon said lug and turn the same with a turning movement of said means to twist the sack.

6. In a fountain pen, a barrel having at one end a conical seat, a unitary member having a part threaded into said end of the barrel and having a set of yieldable vjaws with outer inclined l' aces engaging said seat, whereby when the said member is screwed in one direction the jaws are contracted, and an ink sack, in said barrel, having a part encompassed by the jaws and engaged and rotated thereby when they are contracted.

7. In a fountain pen, an ink sack formed of flexible material, and having at one end an integral head with a reduced lug integral with the head, and socket means adapted to grip said lug and to turn the same so as to twist the sack, said socket means consisting of a rotary split clutch.

8. In a fountain pen, an ink sack` formed of flexible material and having at one end an integral head with a reduced lug integral with the head, and socket means adapted to grip said lug and to turn the same so as totwist the sack, said socket means consisting of a rotary split clutch, including contractive clutching jaws operative to contract on said lug.

9. Operating means for a self filling fountain pen comprising, a spring member formed with sack engaging ends and means for compressing said member whereby said sack engaging ends will engage the ink sack of the penin a -manner to permit the sack to be opera-ted to ll or expel the contents of the same for the purpose specified.

In testimony whereof I have signed my name to this specification.

JOHN M. BEADLES.
