LEAKP'RooF .INKWELL FluedlA Dec. 9, 1940 2- sheets-sheet 1 Patented Dec. 9, 1941 pir 20 Claims.

This invention relates to an inkwell. More particularly, the invention is concerned with a novel type oi" inkwell VJfor use in connection with a desk top. It has now become a widespread custom in institutions of learning and in other places where desks are used, to use desks of the movable pedestal type which can readily be arranged in any desired pattern in a room and which can be stacked up out of the way when not in use. As these desks are not stationary in the sense cf being fixed to the floor, they are subject to being tilted either laterally, forwardly or rearwardly. When inkwells oi the ordinary type, as heretofore used are provided, the ink will sometimes spill out of the well. Often, these desks are provided with lifting tops, into which it is sometimes desirable to have an inkwell fastened.

It is a primary object, therefore, of this invention to provide a vacuum type inkwell, which is equally adaptable to either fixed or movable type desks, and in which there will be no danger, at any time, of any ink spilling from the well.

It is a further object of this invention to provide a vacuum type inkwell, so constructed and arranged, that there will aways be provided lan ink reservoir portion and fount portion for a pen, automatically fed by the reservoir portion.

A still further object of this invention is to provide a slidable closure in a fountain inkwell which is so constructed and arranged that tilting of the inkwell longitudinally thereof in either direction will automatically shift the closure to a closed position so as to thereby prevent spilling of the ink.

A further object of this invention is to provide an inkwell of this type having a slidable closure which will automatically shift to a closed position upon raising of the reservoir end of the inkwell so as to cut off entrance of air and thereby prevent spilling of the ink.

A further object of this invention is to provide an inkwell of the fountain type which includes an auxiliary closed chamber at one end of the main reservoir in which ink is adapted to fllow in the event the fount end of the inkwell is raised, so that in the event the main reservoir is completely filled with ink, the ink in the fount may flow back to the main reservoir and enough ink from the main reservoir will flow into the auX- r iliary chamber to prevent overflow of the ink.

Embcdying the aims aforesaid and others which may hereinafter appear, the invention consists of the novel construction, combination and arrangement of parts as will be more specifically referred to and illustrated in the ac'- companying drawings, wherein is shown an ernbodiment of the invention, but it is to be understood that changes, variations andmodications may be resorted to which fall within the scope of the invention as claimed.

The inkwell, in accordance with this invention, includesl a one-piece composite body part having an inlet and a closure slide shiftably mounted within the body part. The latter is formed of upper, intermediate and lower sections disposed in superposed relation and suitably secured together by heating or otherwise. The sections of the body part may be constructed of glass either transparent or translucent and suitably colored if desired, or such sections may be formed of cellulosic composition material, such as Bakelite, which may also be suitably colored. The top section of the body part may be colored in the manner to concealthe slide.

The body part of the inkwell is generally indicated at A and it is'formed of an upper or outer section l, an intermediate section 2 and an inner or lower section 3. The sections are disposed in superimposed relation.

The section l includes a slab-like upper portion 4 of rectangular contour, which is of greater width and length than any one of the other of the sections. The section I also includes an endless iiange 5 of oval contour. The ange 5 is integral with the lower face 6 of portion 4 and its ends and sides are inset with respect to the ends and sides of the portion 4. The section I has formed integral with the lower face of portion 4 a transversely extending rib 1, which is arranged between and is integral with the flange 5. The rib Iis arranged in proximity to one end of the ange 5. The portion 4 at one side of its transverse median and its end 8 is formed with a ared inlet opening 9 for the passage of a pen into the well. The opening 9 is intersected by the longitudinal median of the portion 4. The latter between the opening 9 and its side edge I0 is formed lengthwise' thereof with a rectangular slot II and -With the transverse median of said slot aligning with the axis of the inlet 9.

The sectionz includes an oval-shapedfslablike upper portion I'2 f an outline corresponding in contour to the ange 5. The portion I2 is secured to the bottom edge and is flush with the outer side edge of ange 5. The `portionf'IZ is formed with a segmental-shaped opening I3 at one end and is also provided witha'fpair `f spaced recesses I4 and I 5zin its upper`ace.to form tracks I6 at its sides and also a support I'I between and aligned with the tracks. The

The'insetting of the"'f1ange 5, with respect to the edges of the portion 4 provides the latter "with an overhang, as indicated at 34, and this '1.5 ,"overhan'g is provided for the purpose of suspending the inkwell in an opening in the desk "toppwhichis provided for receiving the major Lportion. of/ the inkwell` That portion of the inkwell I arranged in the desk top, is adapted to -besec-ured to the latter by any suitable means.

IIn the --use and .operation of this .improved inkwell, vthedevicel isadapted toY be mounted. in

When the top`isv ina normal position, thewell fwlill be. inclined Yforwardly toaslight degree due .tothe inclinationof the desk top, butthis for- .ward inclination will.not materially alect the vquantity of ink which .is positioned in the dipping .well .or fount. "In Figure 8 .the well is vshown in. a`- horizontal positionV and it-will .be noted Ythat Yin-this position, the ink in'the'reservoir24 will lbe 'at a higher'levelthan'the level .-f '.thelink inv the dipping welll29 andthe chamber 2'5. Y.The .auxiliary reservoir'I3 ati this timewill Vbeenipty.

In the event the forward or`free edge of ltheLtop is.raised, the inkwell will .assumesub'stantially the.position' shown in Figure 9. .In this position, the 'slide or valvememberfSIwill gravitationally move downwardly so .as to position the opening32 therein out of. registry with theopenings 9 'and I8. 'The .ink will'ow intothe auxiliary reservoir I3 and will drain atleastpartly out of the dippingwell 29into the main reservoir24..

'Intheeventthe inkwell is .turned to avertical positionv'with lthe `reservoir 24 lowermost, theink from the Well 29 will substantially 'ow .intothe reservoir'24, the auxiliaryreservoir I3 Vprovidin-g sufl'icient space' to receive the ink. from the well 29 so .that in.a verticalposition,`the ink v-`willbe Ientirely contained in .the reservoir '24. Thisobtains in .the event thereservoir'24 is initially completely filled.

In Figure 10, there is .disclosed a second or reversed position of `theinkwell wherein the reservoir '2IJ is raised above the well 29. (In this position the valve or slide 3 I will move forwardly to'theposition shown so as to close the` passage between the openingsv 9 and I8. rTheink in the well or fount 29 will remain .therein and `some Aink from the reservoir 24 .will ow into the chamber 25. However, due to the factthat the slide3| .hasclosedthe openings 9 and I8, the 'airabove the leveLof the liquid in thechar'nber 25 willbe trapped .and in this manner, theink in the chamber 25.will notbe permitted to leak out'of the passages 9 and I 8. It-willbenoted `in'liigure 10.that the ink in thereservoir 24 is ata higher level than the ink in the-chamber 25. "This is due partly to the fact that the ink closes the openingsl between the.reservoir-24 .and the chamber 25 so that a partial vacuum isiormed inthe auxiliary. reservoir I3. and .the rearl upper portion of the reservoir 24. It has been found from actual experience that the inkwell herein shown will not leak ink in the event the reservoir 24 is raised to a Vertical position above the chamber 25.

In Figures 8, 9 and 10 the left side o the inkwell here shown is designated the front which will be disposed away from the desk occupant.
