GEORGE H. HEINDSELIILAN, OF PROVO, UTAH.

SELF-FILLING FOUNTAIN-PEN.

Application filed Becember 28, 1909.

To all whom it may concern:

Be it known that I, Gnonen H. HnixnsnL- MAN, a citizen of the United States, residing at Provo, in the county of Utah and State of Utah, have invented certain new and useful improvements in Self-Filling Fountain-Pens, of which the following is a specification.

This invention relates to fountain pens, and has particular reference to that type of fountain pens which are designed to contain within themselves the means for filling the same.

The invention consists of certain specific details of construction hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a longitudinal section of the device, showing the parts in normal position; F ig. 2 is a view similar to Fig. 1, but with the parts in the opposite position; Fig. 3 is a face view of the upper end of the device indicating the position assumed by certain of the parts preparatory to filling; Fig. fl: is a transverse section on the line all of Fig. 1, and Fig. 5 is a detail sectional view on the line 5-5 of Fig. 2, the end cap being removed.

Throughout the following description and on the several figures of the drawing similar parts are referred to by like reference characters.

The invention illustrated includes a pen barrel 10, adapted to have connection to its lower end in any suitable manner and any desired type of pen and feeding devices, the same constituting a partof this present invention. lVithin the barrel is a flexible bag 11 adapted to carry the ink and supply it through the feeding devices to the pen in a manner well understood in this type of fountain pens. The bag 11 in its normal position substantially fills the interior of the barrel 10.

As is customary in this type of fountain pens there are means provided for the pur pose of compressing or collapsing the bag preparatory to the filling or refilling operation. In this instance such means include a plate 12 which is substantially fiat and coextensive with the bag throughout the greater portion of the length of the latter. The plate is comparatively thin but must be made of some suitable stiff material so that when pressure is applied thereto toward the bag it will collapse the same, driving the in- Specification of Letters Patent.

closed air therefrom. The peculiar means for operating the plate comprise a U-shaped bail or stirrup 13, the ends of which extend in opposite directions and constitute a pair of trunnions 13 in the same axis. The trunnions are ournaled in a pair of bearings 11 in opposite sides of the barrel 10. The portion of the bail 13 between the trunnions is substantially semicircular so as to substantially conform to the form of the barrel and the form of the bag when in normal position, the bag when in normal position extending within the bail between the trunnions thereof. The bail is permanently con-- nected to the aforesaid plate 12 as by a pair of cars 12 to which the bail is pivotally connected, the ears lying on opposite sides of the link 17. A pull rod 15 movably mounted within the barrel and is adapted to slide longitudinally thereof, being adapted to be operated by a finger-piece or knob 16 which extends to the outside of the barrel. The inner or lower end of the pull rod is connected by means of a link 17 to the middle portion of the bail 13, the ends of the link 17 being pivotally connected to the pull rod 15 and bail 13, respectively.

The parts just described are so arranged and proportioned that a pull upwardly or outwardly on the finger-piece 16 will cause the bail 13 to be turned around the axis of the trunnions 13, whereby the plate 12 will be forced against the bag and toward that side of the barrel opposite the pull rod 15. The link 17 may be of any suitable or de sired length, but preferably it is designed to be substantially of such length that when the pull rod is drawn upwardly or outwardly to compress the bag the link will occupy substantially a perpendicular position with respect to the barrel, whereby the compressing devices will be locked in such position as shown in Fig. 2.

The outer end of the barrel 10 is normally closed by means of a cap or plug 18 connected in any suitable manner thereto. As indicated said plug is provided with screw threads 18 whereby the cap may be securely fastened in place. The cap 18 serves not only to close the barrel, presenting a finished appearance, but also serves as a locking means to control the operation of the pull rod 15. The cap is shown as being provided on one side with a groove 18, which when the cap is loosened may be made to register or come into alinement with the outer end of the pull rod 15 and through or along which the said pull rod may be drawn for the purpose above indicated. The pull rod near its outer end is bent sharply as indicated at 15' so as to place the finger-piece 16 in a plane outside of the plane of the main portion of the pull rod and whereby the finger-piece may be grasped with the finger or thumb nail. The extreme outer end of the pull rod lies normally within a notch 10 of the barrel. Then the cap is turned to its normal tight position the groove 18 will be out of alinement with the pull rod and the cap will therefore prevent the pull rod from being drawn outwardly. In order to prevent the pull rod from being drawn outwardly too far it is preferably provided with one or more pro jections or processes 15 which will strike against the ends of the shoulders of the cap forming the groove 18.

With the parts in the position indicated in Fig. 1, assuming that the bag is empty and is to be filled with ink, the cap 18 will be turned so as to bring the groove 18 into position to receive the pull rod 15, at which time the pull rod may be drawn outwardly so as to cause compression of the bag to drive the air therefrom. The operation thus far may be performed at any time, either before or after inserting the pen end of the device into the ink, and the parts will be held substantially in the position indicated in Fig. 2 by virtue of the locking effect of the link 17. After the pen is dipped into the ink a slight downward pressure upon the finger-piece 16 will serve to unseat the link 17 from its locking position and thereafter the resilience of the bag 11 will cause the same to assume its normal position causing the ink to fill the same in the well-known manner. After the parts have been restored to the normal position indicated in Fig. 1 the cap 18 will be turned to lock the same in such position. The device ismade of a small number of parts, and hence is not likely to get out of order.

The several operating devices may be made of any suitable materials, and the relative proportions of the parts may be varied to a considerable extent if desired without departing from the spirit of the invention hereinafter claimed.

I claim:

1. In a self filling fountain pen, the combination with a barrel and the resilient ink bag therein of a ball journaled within the barrel on a transverse axis and extending upon opposite sides of the bag, a plate associated with the bag and operable by said bail, a pull rod connected to the bail to swing the same on its axis to cause the plate to compass the bag, and a cap connected to the upper end of thebarrel to engage and thereby control the operations of said pull rod, said cap being rotatably connected to the barrel, substantially as set forth.

2. In combination, a pen barrel, a col lapsible ink bag therein, means to cause the bag to collapse, said means including a pull rod, and means to control the movements of the pull rod, said last mentioned means comprising a cap having rotary connection to the outer end of the barrel and being provided with a longitudinal groove adapted to register with the outer end of the pull rod in one position and in another position to hold said pull rod in its normal inoperative position.

In testimony whereof I affix my signature in presence of two witnesses.
