Application filed February 16, 1917. Serial No. 149,081.
To all U'wm it 'may concern Be it known that I, FREDERIC E. SToREn, a citizen of the United States, residing at Somerville, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Fountain-Pens, of which the following is a specification.
My invention is an improvement in fountain pens, more particularly applicable to that class of fountain pens known as selffilling pens, in which the ink is contained in a flexible and resilient rubber sack with-v in the hollow handle or fount of the pen.
In the drawings:
l,Figure l is a central, longitudinal section of a fountain pen embodying my improvements;
Fig. 2 sleeve;
Fig. 3 is a detached view of the pen feed, ink sack and presser bar, organized together; and
Fig. 4 is a cross section on line 4-4 of Fig. l, on an enlarged scale.
ln selfhlling fountain pens in which a soft rubber, collapsible ink sack is employed to receive and contain the ink, as is well known, the filling has been accomplished. by collapsing the scft rubber sack and inser-ting the pen point into an ink supply and then allowing the soft rubber sack to expand and draw in a supply of ink through the pen point and feed bar. Numerous ways and means havehitherto been employed to effect the collapsing of the ink sack and to control its subsequent expansion, and one of the most simple and effective of such ways and means has been to form an aperture through the wall of the hollow handle or fount7 of the pen, in which the ink sack is contained, so that the sack could be reached by-the linger of the user through the aperture and the sack collapsed and then In order that this method might be successfully employed it was necessary to provide means by which the pressure of the linger upon one part, near the middle of the length of the sack, could be made effective throughout its length and also to provide means by which the aperture in the wall of the handle might be closed after the sack had been filled, to the end that the filled sack might not, by accident, be collapsed, and its contents thus is a longitudinal section of the ejected. I have provided, to assist the finger of the user in collapsing the ink sack,
when desired, an improved presser bar, which is mounted in connection with the ink sack in a novel and useful manner, and I have also provided means for closing the aperture in the handle and for keeping it closed, when not in use.
In the drawings, I have shown a fountain pen provided with my devices, in which A is the fount or handle, having an aperture, a therethrough. The pen section I), carries the feed bar, f, and thev writing point or pen 79. 'Io the inner end of the pen section is secured the open mouth of the soft rubber ink sack S, all in the well known manner. Along that side of the sack S which is directly beneath the aperture, a, when the Directly beneath the aperture, a, I form iny or on the presser bar a protuberance or linger piece, Z), with which the finger of the user may engage and thus make it possible to give the most effective pressuie to the ink sack.
maintain the presser bar B, in proper relation with the sack S, have generally involved levers or links connecting the bar with some fixed part of the handle and serving to hold the presser bar in the desired position with regard to the ink sack and aperture. In my improved pen the presser bar is positioned most elfectively by cementing upon the sack one or more retaining bands or patches, s. The presser bar B is preferably curved in cross section and it is preferably formed of thin, stamped metal. To secure the bar B in proper position, the bar is forced between the band or patch s',
and the sack, the band being disengaged in The means` hitherto employed to fix and iaV rl`his has heretofore been accomplished by fittingl upon the handle or barrel of the pen, an outer sleeve, to be. moved longitudinally ofthe. barrel to expose the aperture or to be moved in the opposite direction to close or Cover the aperture. In order that this sleeve ishould satisfactorily perform its function, Sit has been necessary to fit it with some care, in order to insure a ht which would be tight or close enough to cause the sleeve to retain its position, wherever it was set andl at the v saine time to be loose enough to permit the sleeve to be shifted as desired, .with reason.
able ease. This iitting was a troublesome iminor problem of fountain pen manufacture and relatively expensive in consequence. I.
obviate this diiiiculty and expense Lby providing means to positively lock the sleeve, D,
in operative position, so that it is no longerHA necessary to take greattrouble about an accurate frictional fit between the sleeve D and the handle, fount or barrel A. To this end I form upon the rear end of the barrel.
A a short screw threaded extension c and ,in the inner surface of the closed end or i head/of the sleeve I form a cooperating' screw threaded recess, o. lVhen the sleeve D is mounted upon the barrel A by passing it on to the rear end, it is of such a length that the sleeve Will pass over the aperture,
a, asthe extension, 0, engages the recess, c. The sleeve-being turned axially the parte 0, c', screv7 together and the sleeve D is advanced. bviously, unless the sleeve is axi- -ially rotated it cannot be moved longitudinally tov uncover the aperture, a. In operation the sleeve D is thus normally locked in position and is only unlocked and retracted when it is desired to fill the pen. In order -to connect the sleeve D with the barrel A in suchifashion Vthat the sleeve cannot be easily removed, I form Within the sleeve D an annular groove, CZ, preferably shaped in cross section, substantially as appears in F ig. 2, and upon the outer surface of barrel A,
at a. suitable position, as' indicated, I formY an outstanding, -liexible finger (l, preferably Y integral vWith the barrel A, the free and upstanding end of the finger pointing toward zthe pen end of the barrel.
It Willbe observed that one wall, ci of the groove d is at a considerable angle to the axis of the sleeve, and it is this Wall that is engaged by the linger CZ when the sleeve is retracted to uncover aperture, a. The Wall Mis of such an angle that it serves as a stop for the sleeve in coperation with the finger d, but still permits the sleeve tovedge the linger doivn ifsuiiicient force is applied, When it is desired to disassemble the parts.
lVliile I have described .the two elements of the screw-thread sleeve-locking device in a speeilicmanner, illustrating` `what I conceive to ybe the best and most economical form, it is obvious that the idea of means could be embodied in other specific forms, in vhich tlie'outer surface of the handle is provided With screw threads andthe inner siii*- face of. the sleeve with Corresponding threads, to engage and cooperate, afterl the main-movement of the sleeve has been ef-l fected by a slidingmovement, theV Screw threadsbeing utilized merely for locking purposes and being disengaged during a great part of the movement of the sleeve.
I claim:
In a fountain pen, the combination of a f withiniiearthe open end and a threaded re,-4
cessV in the closed rear end thereof; a threaded boss upon the rear end of the hollow1 handle; all organized to cause the tongueV upon the handle to engage the circumferential groove Within the sleeve and stop the i sleeve when the sleeve is Withdrawn to inoperative position and to cause the threaded boss andY recess to engage when the sleeve is advanced to operative position.
Signed by me at Boston, litiassacliusetts, this 15th day of February, 1917.
