PEN-FILLING DEVICE.

Specification of Letters Patent.

Patented Dec. 30, 1913.

Application filed February 14, 1912. Serial No. 677,616.

To all whom it may concern:

Be it known that we, HUSTON TAYLOR, of Pittsford, county of Monroe, and State of New York, and JAMES I'IALL TAYLOR, of Chicago, county of Cook, and State of Illinois, both citizens of the United States, have invented certain new and useful Improvements in Pen-Filling Devices; and in order that others skilled in the art may understand, make, and use the same we give the following specification, of which the accompanying drawings form a part.

. Our invention relates to devices for filling pens or writing implements of the class generally known as fountain pens, including also stylographic and other pens having an ink reservoir, and has for its object to provide a simple and efficient pen filling device which shall not only easily and quickly fill such pens with safety and cleanliness but which shall also be combined with and form a part of a reservoir or receptacle for ink.

The nature of the invention and the manner in which the same is used will appear in the following specification taken in connection with the accompanying drawings.

In said drawings, Figure I represents an elevation of the device in an inverted posi tion with the pen inserted for filling. Fig. II is a vertical sectional view of one form of the device in ordinary upright position. Figs. III and IV are similar views, parts being shown in elevation, illustrating modifications. Fig. V is a similar view part being broken away and showing more particularly aform of closure or cap. Fig. VI is a View similar to Figs. III and IV but showing a modification. Fig. VII is a view similar to Fig. V showing a modified form of stopper or cap. Figs. VIII and IX are details.

Referring to the drawings our invention comprises a receptacle or bottle for the ink indicated by the numeral 1. This receptacle or bottle may be made of any suitable mate-- rial which will not affect or be affected by the ink contained therein and which is suitable for shipping and sale. The precise form of the receptacle 1 is not essential though it preferably should have a relatively wide neck 2 to accommodate and support the flexible and elastic closure 3 which will be more particularly described below.

The member 3 forms a closure for the receptacle 1 protecting the contents of the latter from spilling and from exposure to the air. Said member 3 also provides the operating member for filling the pen and to that end 15 formed with an inverted dome-shaped or cup like portion 4 narrowing downwardly and provided with a central or axial tube 5 open at its outer end where it is provided with a flaring or tapered mouth 6 and communicating at its inner end 7 With the interior of the receptacle 1. The central tube portion 5 is preferably formed integral with the dome like portion 4 though it may be formed separately and united to said portion at. The closure member, including the dome like portion and the central tube are preferably formed of rubber or other suitable flexible and elastic material. The outer end 6 of the tube 5 is made flaring or tapering in order to receive and make a tight joint with the pen to be filled. The closure 3 as described is securely clamped or united to the receptacle 1 to form a tight joint therewith in any convenient manner being preferably provided with a peripheral flange 8 which extends over the lip of the neck portion 2 of the ink receptacle; and a clamping device such as a threaded apertured cap or ring 9 engaging the outer threaded portionv 10 of the neck 2 is secured to said neck to clamp said closure 3 thereto by its flange 8. The cap or ring 9 extends over the mouth of the receptacle and is provided at its center with an aperture 11 through which passes freely tube member 5. r The foregoing description applies more particularly to II of the drawings.

In Fig. II the inner lower portion of the neck 2 of the receptacle is shown provided with an inwardly extending flange 12 to form a seat to support a disk 13 forming a seal for the liquid in the receptacle when the device is not in use to prevent spilling of the contents and to enable the device to be handled in the trade with security. Said disk also forms a seal or closure for the lower end of the tube member 5 which rests thereon. vAs shown in Fig. VIII said disk is provided with an annular series of perforations lt (see more particularly Fig. VIII, in which said disk is shown separately). Said apertures or perforations 14 are so arranged that they are closed by the walls of the tube 5 when the device is not in use.

It will be understood that the disk will be of'such size as to fit the neck of the bottle suflieiently tight so as to be held in place when the bottle is inverted for use in filling the pen. Various other forms of the sealing disk 13 are shown in the drawings. For example in Fig. 111 said sealing disk 13 instead of being supported upon a flange at the lower part of the neck of the receptacle, as in Fig. 11, is supported from the mouth or lip of the neck of the receptacle by means of arms or depending supports 15. A plan view of this form of the disk and its supporting means is shown separately in Fig. IX. In Fig. 1V another form of supporting disk is shown in which the same is supported from the bottom of the ink receptacle upon a grid 16, the legs of which extend from the disk to the bottom of the receptacle. Still another form of sealing device for the lower end of the tube member 5 is shown in Fig. V1 in which said sealing device is made integral with the receptacle by forming the bottom thereof with an upward inner extension 17 of cone shape, the apex of which engages with the lower end of the tube member 5 and forms a seal therefor.

A closure or cap is provided for the upper end 6 of the tube member 5 and such closure is shown in one form in Fig. V where it is represented as a screw cap 18. In this view the clamping member or ring 9 which clamps the receptacle closure 3 to the receptacle is formed around its central opening with an upwardly extending threaded collar 19 with the threads of which the cap 18 engages, said cap being similarly threaded for that purpose. The cap 18 is provided with a depressed central portion 20 to form a seal for the mouth of the tube member 5.

in Fig. V11 a stopper 21 suitably formed with a flanged head is shown for closing the end of the tube 5.

Having described the invent-ion and the illustrations thereof from the drawing, the operation of the same is as follows: The pen to be filled is inserted into tube member 5, the flaring mouth of which enables a tight joint to be made with various sizes of pens. The pen point occupies the interior of the tube. The receptacle with the inserted pen 22 is then inverted as shown in Fig. I and the pen and tube 5 are grasped by the fingers and alternately pulled downward or extended and allowed to retract. The closure 3 being of elastic and flexible material acts as a diaphragm and in its downward or with drawn position the domelike diaphragm collapses and thus enlarges the interior volume of the receptacle creating a suction and rarefying or xhausting the air in the pen and upon return of the diaphragm to normal position the ink flows in to take the place of the air withdrawn from the pen. It will be noted that when the tube member 5 with the pen therein is withdrawn or extended the inner end thereof is withdrawn from the disk 13 and the ink is therefore free to flow into the pen as described. As the air passes from the pen it bubbles up through the ink to the space above where it is away from the pen and when the diaphragm is returned to its normal position the volume of the in terior becomes again normal and the ink flows in through the feed ducts of the pen. The operation is repeated until all the air is withdrawn from the pen, and the pen is filled with ink.

It will be observed that the ink is confined within the tube 5 immediately about the point of the pen and the eflect ofthe repeated exhaustions and compressions due to the alternate collapsing and expanding of the diaphragm 3 is applied positively and directly to the ink within the tube 5 immediately about the pen point, and as this portion of the ink is confined by the walls of the tube and also by the sealing disk the action of the device in filling the pen is more rapid and eflicient than in other pen filling devices with which we are acquaintedfewer reciprocations of pen and tube being required to fill a pen.

A further advantage lies in the dome-like diaphragm being contained within the receptacle where it is less exposed to deterioration and injury and a more compact form of device or package results, occupying less space.

What we claim is:

1. A combined ink-receptacle and pen-filling device having in combination a receptacle for the ink, a central tubular member having one end extending within the receptacle and its other end extending outwardly therefrom, said outer end formed to make air and fluid-tight connection with the inserted pen, the inwardly extending portion of said member forming a chamber to receive the point and feed-ducts of the pen, an elastic pumping diaphragm or member united with and extending from the lower interior portion of said tubular member to and over the lip of the ink receptacle, and a centrally-apertured clamping cap engaging the mouth of the ink receptacle and clamping the diaphragm and tubular member fluid-tight thereto with the outer end of the tubular member freely passing through said aperture.

2. A combined ink-receptacle and penfilling device having in combination a re ceptacle for the ink, a central tubular member having one end. extending within the receptacle and its other end extending outwardly therefrom, said outer end formed to make air and fluid-tight connection with the inserted pen, the inwardly extending portion of said member forming a chamber to receive the point and feed-ducts of the pen, an elastic pumping diaphragm having the form of an inverted dome united to and extending from the lower, interior portion of said tubular member to and over the lip of th ink receptacle, and acentrally-apertured clamping cap inclosing the lower portion of the tubular member and the diaphragm, said cap engaging the mouth of the ink receptacle and clamping the diaphragm fluidtight thereto, with the outer end of the tubular member freely passing through said aperture.

3. In a device of the character described, the combination with an ink receptacle, of an elastic collapsible dome-like diaphragm secured to the mouth of said receptacle and extending within the same, an axially disposed hollow stem connected to the crown of said diaphragm within said receptacle and extending outwardly from the same, said stem forming a chamber for the reception of the point of the pen to be filled and having its outer end formed with an orifice to receive and make arclose joint with the pen and its inner end open to the interior of the ink receptacle, a sealing device supported within the receptacle to close normally the inner end of said stem, said stem forming means for alternately collapsing and expanding said diaphragm, substantially as and for the purpose described.
