page_text: I, GEORGE DANIEL SPIELMAN of Shillito Street, Cincinnati, County of
Hamiltou, State of Ohio, U.S.A., Manufacturer, do hereby declare the nature of
this invention to be as follows:-
This invention relates to an ink well or other like receptacle for liquids in which
a spring dip cup may be pressed down by the pen or by a special press piece into a
bottom chamber to be supplied with the liquid. Above the bottom chamber the
receptacle is enlarged so as to contain a comparatively large quantity of the liquid
and overflow therefrom into the dip cup when this is pressed down against the
resistance of a spiral spring. In the raised or normal position the dip cup, from
which the liquid to be used is taken, engages by upwardly projecting prongs
against the underside of a funnel shaped top so as to a form a liquid seal between
the main body of liquid and the liquid in the dip cup. The funnel shaped top is
formed with hook like projections to take over corresponding projections on the
body of the receptacle and is fixed by means of inclined projecting parts. The top
is provided with a cover.

I, GEORGE DANIEL SPIELMAN, of Shillito Street, Cincinnati, County of
Hamilton, State of Ohio, U.S.A., Manufacturer, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention relates to ink wells and other like articles such as marking pots,
sponge holders and glue receptacles, the object being to provide ink wells or other
liquid holding receptacles, with a device for exposing a limited quantity only of the
liquid, the major portion of the same being protected against dust and evaporation
by a liquid seal formed by the liquid exposed for use.

page_text: Fig. 1 is a view of an ink well partly in plan and partly in section. Fig. 2 a
vertical section of the same.
Fig. 3 a similar view shewing the supplemental reservoir or dip cup in its
depressed position.
Fig. 4 a detached view of the funnel shaped top, and
Figs. 5 and 6 other details.
1 is the body portion provided with a reservoir composed of an upper chamber 2 a
restricted lower chamber 3, and an inclined ledge 4 constituting a portion of the bottom
of the larger chamber 2 and leading directly to the top of the centrally located
restricted lower chamber 3. The mouth 5 of reservoir 1 preferably terminates in
the form of an upwardly projecting annular ring 6 having on its outer surface
oppositely located projections 7 the bottom faces of which are inclined one in one
direction and the other in the opposite direction. The lower inner end of said
mouth or neck is inclined as shewn. Dip cup or supplemental reservoir 9 is
provided with a series of upwardly projecting prongs 10 the lower ends of which
constitute abutting surfaces for the upper end of coil spring 11 whereby the dip cup
is yieldingly supported in its normal or operative position as shewn in Fig. 1.
The lower end of the coil spring 11 rests on the bottom of chamber 3 or reservoir 1.
The dip cup in its normal position rests with its prongs 10 against the lower face
of the funnel shaped top 12 the rim of which latter is provided with an annular
groove 13 and oppositely located recesses 14 in open communication with said
annular groove. The funnel shaped top 12 is removably secured in its operative
position by registering the recesses 14 with the projections 7 and slightly turning
top 12 to the right, the projections then entering the annular groove 13 and the
lower face of top 12 forced against the upper face of the ring surrounding the
opening and thus locking the top. In this position the prongs 10 take against
the bottom face of the top and as they project above the rim of the dip cup, an air
space between the latter and the reservoir 1 is secured. The funnel shaped part
of top 12 is adapted to project within the dip cup to near the bottom, but leaving
sufficient room for a free circulation of the liquid. 15 is a cover for closing the ink
well when not in use.
In the bottom of the dip cup or supplemental reservoir 9 is provided a seat 16 for
the reception of one end of a pen, rod or other device 17 by which the dip cup may
be depressed (Fig. 3).
In the operation of the device the reservoir is filled or partly filled by either
removing the funnel shaped top and supplemental reservoir, or by simply depressing
the latter until its upper edge is below the lower edge of the funnel. After
a sufficient quantity of liquid has been deposited in the reservoir the supplemental
reservoir is filled by depressing it. It is then permitted to rise and as the liquid
contained therein reaches the lower edge of the funnel, the air pressure from the
outside against the exposed liquid prevents the liquid from rising within the funnel
above the lower edge of the latter, the liquid thereby displaced running over the
upper edge of the supplemental reservoir into the main reservoir. The liquid thus
exposed is just sufficient to cover the nibs of a pen and as it is used up, is fed to
the mouth of the funnel from the space between the side wall of the supplemental
reservoir and the inner face of the funnel. When the liquid between the inner
face of the funnel and the wall of the supply reservoir shall have been exhausted
thus exposing the lower end of the funnel and destroying the liquid seal, the
supplemental reservoir should be again depressed for filling, as before.
If from any reason the pen or other device employed for depressing the
supplemental reservoir should slip thus suddenly releasing said reservoir, the
liquid would be prevented from flying out by the atmospheric pressure above, aided
by the air cushion within the reservoir and by the friction encountered by contact
with the end of the funnel. I have described two chambers of different sizes the
smaller adapted to receive the supplemental reservoir. While such a construction
economises the liquid and prevents waste I would have it understood that I do not

page_text: limit myself to such a construction nor to the details of the supplemental reservoir
nor to the manner of securing the funnel shaped top in place as my invention
comprehends broadly a reservoir carrying a funnel and a yieldingly supported
supplemental reservoir located within the main reservoir, and adapted when in its
normal position to receive the free end of the funnel and form a liquid seal
therewith.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. An ink well consisting of a main ink reservoir, a funnel extending into the
main ink reservoir and a supplemental reservoir yieldingly supported with its
upper edge above the lower end of the funnel and constructed to hold a supply of
ink away from and out of communication with the ink in the main reservoir,
substantially as described and shewn.
2. An ink well comprising a main ink reservoir, a funnel extending down into
the latter, a supplemental reservoir having a closed bottom whereby to hold
a supply of ink independent of and elevated above the ink in the main reservoir,
said supplemental reservoir normally held at the bighest point in the main
reservoir with its upper edge above the lower end of the funnel, substantially as
described and shewn.
3. The combination of a main reservoir having an enlarged and a restricted
chamber, a funnel shaped top projecting therein, a supplemental reservoir provided
with prongs adapted to engage the funnel shaped top above the lower end of the
latter and a spring for yieldingly holding the supplemental reservoir in its elevated
position, for the purpose specified, substantially as described and shewn.
4. The general arrangement and combination of parts constituting the ink well
referred to, substantially as described and shewn.
