INKSTAND.
SPECIFICATION forming part of Letters Patent No. 412,601, dated October 8, 1889.
Application led May 21, 1889. `Serial No. 311,629. (No model.)
To all whom t may concern.-
Be it known that 1, JOHN R. COOPER, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented a new and useful Improvement in Inkstands, of which the following is a specification.
My invention relates to that class of ink' provide a cheap and efficient ink-holder that will yield a supply of ink forA filling the pen at each dip of the same, any surplus fluid immediately receding within the Yair-tighty holder, thus preventing the thickening of the ink by its Contact with the open air by which the flow ofthe same becomes retarded. I atetain this object by the mechanism illustrated in the accompanying drawings, in which- Figure l is a perspective view of the complete device. Fig. 2 is a sectional view taken through the vertical center of the same. Fig. 3 is a cross-sectional view of a modification; and Fig. 4. is a perspective view of the pendip detached, showing (in dotted lines) the flange for preventing theoverflow of any surplus ink. Y
Similar letters refer to similar parts throughout the several views.
The ink-holder A, provided with the dis; charge-opening A and stand B, may be made entirely of glass or other suitable material; or, if desired, the. supporting-stand may be of wood or metal and the ink-holding receptacle of glass. I prefer glass for the main ink-holder on account of its transparency, whereby it may be seen when the ink is low in the holder and in need of replenishing.
C is an auxiliary ink-receptacle of any desired form secured to and forming an extension to the neck or discharge-opening A', and having the pen-dip D securely attached thereto. This part C is hollow, of course, (as Awell as A,) and made of rubber or some other flexible material, the walls of which are quite thin, so as to yield upon a slight pressure for apurpose which will presently appear.
E is a stopper to the opening centrally made in the bottom of the stand, through which opening the ink passes while in the act of filling the ink-holder.
The pen-dip mouth-piece D is made tapering or funnel-shaped, and is provided (upon the enlarged end) with a iiange ol, projecting inward toward the axial center, by which any overiiow of ink is prevented when in practical use. The ink-outflow opening D of this pen-dip mouth-piece is made small, so that but a diminutive quantity of ink will pass as the iiexible portion of the ink-holder is pressed, which process will now be explained.
The flexible ink-holder is placed below the main ink-receptacle, so that it will at all times, by the force of gravity, remain filled with ink from the upper reservoir, and'when filled any pressure upon the outside will cause a corresponding depression upon the inside of the' wall with a consequent ejection of a portion of the fluid from therein. Now, in practical use, as the pointof the pen is placed within the orifice D and a slight inward pressure given the ink immediately passes through the orifice and fills the pen, which, when removed, the flexibility ot the part C causes it to assume its normal position, sucking back any of the iiuid that may remainin the opening, the atmospheric pressure sealing the orifice until the actis repeated, thus at all times keeping the ink free from exposure to the air and preventing the thickening of the iiuid by such exposure.
To prevent any overflow of ink by the mouth ot' the pen-dip consequent upon too great a pressure, the flange d is provided, which insures safety from any such overflow, even upon undue pressure.
In the modification, Fig. 3,I place the iiexible holder within the body of the stand and directly underneath the non-exible inkholder, with the ink-filling oritice made upon the lower side of the flexible holder, the contents passing therefrom into the main holder instead of entering direct, as is shown in Figs. l and 2, the principle being the saine, each ,working eqpually well. 4
I do not desire to confine myself to the IOO specic location of the lling-aperture nor the cylindrical form of the parts, as any desired shape may be given the inkstand with like results. The entire ink-holder may be of one part and made flexible, being mounted upon a rigid foundation; but this endangers the accidental displacement of the ink from excessive pressure upon this flexible part, and therefore an entire closure of this flexible part, as in C, Fig. 3, may be considered` preferable.
Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. The combination, with an ink-reservoir provided with a illing opening,r closed by a removable stopper and mounted upon a rigid supporting-stand, of the flexible ink-holder at the base of the reservoir, and having the pen-dip mouth-piece by its minute outflowopening directly attached to the flexible inkholder below the body of ink, whereby the pressure of the pen alone in the mouth-piece will, by the contracting of the flexible inkholder, cause suioient ink to gravitate into the pen-dip for filling the pen, the residue of ink upon the removal of the pressure and the resumption of a normal position of the parts returning to the ink-holder, substantially as described, and for the purpose herein set forth.
2. The combination, with the ilexible inkholder mounted upon a rigid stand, of the mouth-piece provided with the minute opening connected directly to the lexible inkholder below the body of ink and having the inwardly-extending flange upon the open edge of the pen-filling mouth-piece for the prevention of an overilow of ink, substantially as described and herein set forth.
