Description

N 0 S m R E B 0 R F G FOUNTAIN PEN FILLER.
APPLICATION FILED MAY 26, 1908.
Patented Mar. 29, 1910.
lvihwoazo I GEORGE FRANCIS ROBERTSON, OF CHARLOTTE, NORTH CAROLINA.
FOUNTAIN-PEN FILLER.
Application filed May 26, 1908.
To all whom it may concern:
Be it known that I, Gnonon FRANCIS Ronnn'rson, a citizen of the United States, residing at Charlotte, in the county of Mecklenburg and State of North Carolina, have invented certain new and useful Improve-. ments in Fountain-Pen Fillers, of which the following is a specification.
This invention relates to fountain pens, and more particularly to fillers therefor and has for an object to provide a device which may be conveniently applied to fountain pens of various forms without injury there to and which will effectively serve as ameans for filling the reservoir of the pen without soiling the hands of the user.
A further object of this invention is to provide an attachment of the above described character for use in connection with fountain pens by means of which their reservoirs may be filled by suction in a convenient and effective manner when the nib of a pen is inserted within an ink container.
Other objects and advantages will be apparent from the following description and it will be understood that changes in the specific structure shown and described may be made within the scope of the claim without departing from the spirit of the invention.
In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a sectional view of a fountain pen showing the application of the present invention thereto, the same being in an inoperative position Fig. 2 is a similar view the device being in an operative position, Fig. 3 is a detail sectional view of a portion of the piston rod and head, Fig. 1 is a transverse sectional view on the line 4L-1 of Fig. 1. s
Referring now more particularly to the drawings, there is shown a fountain pen of usual construction comprising an elongated barrel 11 having a closed head 12 at one end and which is provided at its other end with a nib 13.
The head 12 is provided with a centrally located threaded passage 14, and slidably mounted within the barrel of the pen there is shown a piston rod 15 which is also disposed for movement in the passage 1 1 formed in the head 12. The piston rod, at its outer end, is provided with a milled or knurled head 15, and inwardly of the head,
Specification of Letters Patent.
Patented Mar. 29, 1910.
Serial No. 435,184.
the rod is threaded as shown at 16 for engagement at times as will be hereinafter described in the threaded passage 1 1 formed in the head 12.
The rod 15, at its extreme inner end is also threaded as shown at 17 and is thus arranged to receive an internally threaded collar 18 provided with an internally and externally threaded sleeve 19. The sleeve 19 is thus arranged to receive a piston head 20 which is preferably formed of soft rubber, cork or the like, and which is securely held in place upon the sleeve by means of a disk 21 having an internally threaded passage 22 for engagement with the externally threaded portion of the sleeve 19.
The internal and external threads of the sleeve 19, are right and left hand thread respectively. The interior right hand threads of the sleeve are adapted to be engaged by the threaded extremities of the. rods 15, whereby the piston may be retained in its operative and inoperative positions. It will be understood that the frictional engagement of the piston 20 is such that no rotative movement thereof will occur when the end 17 of the rod 15 is released from engagement with the interior threads of the sleeve.
Upon reference to Fig. 1 of the drawings, it is obvious that the device is in an inoperative position, and upon movement of the head 15 in an outward direction it will be understood that the rod 15 which is carried thereby will be moved in a position whereby its threaded end 17 may be securely engaged with the internally threaded portion of the sleeve 19.
Upon reference to Fig. 2 of the drawings it will be seen that the nib 13 of the pen may be inserted within a suitable ink container, and upon movement of the rod 15 in an outward direction, it is obvious that ink may be drawn by suction into the barrel 11 of the pen.
When the device is not in use the threaded portion 17 of the rod may be conveniently disengaged from the sleeve whereby the pis ton head may lie upon the underside of the cap 12 at which time, the threaded portion 16 may be engaged in the passage 14 formed in the head whereby the head 15 may be tightly engaged against the outer side of the head.
It will thus be seen that a simple, cheap and durable device is provided which may be applied to fountain pens of ordinary con- 1 exterior, right and left hand threads respecstruction and which will automatically serve to fill the barrel of the pen without soiling the fingers of the user.
What is claimed is In a fountain pen filler, the combination with a barrel having a threaded aperture formed ififlie upper end thereof, of a piston rod threaded at its ends, slidably disposed iii said barrel, one of the threaded ends of said rod being adapted to engage in the aperture in said barrel, a knurled head secured to the upper end of said rod, a collar disposed on the lower extremity of said rod, said collar having a sleeve integrally formed therewith and provided with interior and tively, the lower end of said rod being engaged with the interior threads of said sleeve, a fle ible piston engaged with the exterior Threads of said sleeve, a washer threaded on said sleeve adapted to clamp said piston in position against the collar, said sleeve being adapted to have threaded engagement with the upper end of said rod to retain the piston in inoperative position. In testimony whereof I aflix my signature, in presence of two witnesses.
