PROVISIONAL SPECIFICATION
An Improved Ink Well.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a com-
munication to me from abroad by Joseph Antes, of Rockford, Illinois, U.S.A.
Inventor,) to be as follows:-
This invention relates to an improved ink well which is arranged in a suitable
casing in such manner that it can be raised or lowered as desired, according to the
quantity of ink contained within it, and thus limit the dip of the pen.
An ink pot constructed in accordance with this invention consists of a casing
preferably of a circular form, which is provided with a cover having an opening in
its top. A removable ink cup, when in its normal position, is supported beneath
said opening, and a vertically sliding rod passes through the cover, and has a con-
nection with the cup whereby said cup can be raised or lowered.
A vertical tube having its lower end closed has a suitable spring within it,
which is connected to the vertical rod aforesaid, and serves to hold the ink well in
its normal position. A suitable packing ring surrounds the rod, and when the cup
is raised, serves to close the opening, through which the rod passes, and thereby
make an air-tight joint between it and the cover.
The cover is preferably constructed of glass, and the rod which supports the ink
emp is preferably constructed of some non-corrosive material.
Dated this 16th day of August 1890.

An Improved Ink Well.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a com-
munication to me from abroad by Joseph Antes, of Rockford, Illinois, U.S.A.
Inventor,) and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The object of this invention is to construct an ink-well which will contain in
reserve a supply of ink, and in which but a small quantity of ink is exposed.
In the accompanying drawings,
Figure 1 is an isometrical representation of an ink-well embodying the features
of my invention.
Fig. 2 is a vertical central section of the same, in which the ink-cup is in its
normal position.
Fig. 3 is also a vertical central section of the ink-well shown at Fig. 1, in which
the ink-cup is lowered to a position which it will occupy while being filled with
ink.
The ink-well shown in the drawings is, in the main, constructed of glass of any
suitable pattern, and which may have its exterior surface ornamented to suit the
requirements of the trade. The lower portion 1, in this instance, is of cylindrical
form, and is provided with an outwardly-projecting flange 2. The portion 3 above
the flange is reduced in size. The upper portion or cover is also of cylindrical

page_text: form, having its under face recessed, said recess being of a size to receive the upper
portion 3 of the lower section of the ink-well. The inner surface of the vertical
wall of the recessed portion of the cover and the outer surface of the reduced
portion 3 of the lower section of the ink-well have a ground-glass-joint connection,
so that when the parts are placed together in the position shown in the drawings
an air-tight joint is formed, the object being to prevent the admission of air to the
reserve supply of ink within the well to prevent its evaporation and the consequent
thickening of the ink within the well. An ink-cup 5 is preferably constructed of
glass, having a reduced portion 6, the outside of which is ground, as in the
manufacture of glass stoppers for bottles. The upper portion of the cup fits into a
recess 7, formed in the under side of the cover, and when in its raised position
comes in contact with a packing-ring 7, of rubber or other suitable material,
secured within the recess, thereby forming an air-tight chamber. The cup proper
is supported by its lower portion being fitted into a bracket 8, having a connection
with a vertically-moving rod 9, which passes through an opening in the cover. A
disc of rubber 10, or other suitable packing, surrounds the rod 9, and when the
is in the position shown in Fig. 2 sald rubber disc closes the opening through which
the rod passes through the cover.
The rod and bracket are constructed of some non-corrosive material, such as hard
rubber. The upper end of the rod 9 is provided with a cap 11, having its upper
face concaved, which forms a place for the finger. From this cap laterally projects
a collar 12, which surrounds a spring-containing tube 13. This tube passes through
the top of the cover, and has a shoulder 14, which rests on the upper surface of the
Cover. A portion of the tube which extends below the cover is in screw-thread
form, upon which is turned a nut 15, which when turned up against the underside
of the cover firmly clamps the tube in position and makes an air-tight joint between

placed a spiral spring 16. A plug 17 is placed within the tube after the spring has
been placed in position, and has a connection with the collar 12 by the screw 18,
passing through the collar into the plug through a vertical slot 19. The upper
end of the tube 13 is screw-threaded, and when the parts are placed in position, as
shown in the drawings, a screw-threaded cap 20 is turned on the upper end of the
tube thereby preventing the displacement of the parts and closing its open end, this
tube, its various parts and connections with the rod 9, are also preferably made of
hard rubber, excepting the spring, which by being placed in the tube is protected
from the action of the ink.
Upon the rod 9 is pivoted a cover 21, which can be moved to close the
opening 22, formed through the cover over the ink-cup when the well is not
in usc.
In use the cover portion of the well is removed and the lower portion is nearly
filled with ink. The cover portion is then placed in position and by pressing on the
rod 9, the ink-cup is made to descend until it is filled with ink, when by releasing
the rod its spring connection with the cup will cause it to assume its normal position,
as shown in Figs. 1 and 2, and this operation may be repeated until nearly all the
ink has been used.
When the parts are in their normal position, the main body of ink within the
well is protected from the action of the atmosphere, and is only exposed to the
atmosphere during the refilling of the cup. This cup is made detachable to permit
of its being cleansed when it is necessary to do so. By employing an ink-cup in
this manner the sediment of the ink will remain in the bottom portion of the ink-
well and only the pure ink will be taken up by the cup for use.
By means of the flange 2 the ink-well may be suspended in an opening formed in
the upper surface of a table or other support, thereby exposing to view only the
upper portion of the well, which in many instances will be preferable where a high
ink-stand is not desirable; but it is evident that ink-wells may be made without
this supporting-flange and still be within the meaning of my invention.

page_text: Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what I
claim is:
1. In an ink-well, the combination of a lower section, a cover thereto having an
opening in its top, a vertically sliding-rod passing through the cover, and an ink-
cup supported by said rod in a removable manner, for the purpose set forth.
2. In an ink-well, the combination of a lower section, a cover thereto having an
opening in its top a removable ink-cup when in its normal position supported
beneath said opening, a vertically-sliding rod passing through the cover and having
a connection with the ink-cup, whereby said cup can be raised or lowered, a vertical
tube having its lower end closed, a spring within the tube, and a connection between
the spring and vertical rod outside of the ink-well for holding the cup in its normal
position, substantially as set forth.
3. In an ink-well, the combination of a lower section, a cover thereto having an
opening in its top, a removable ink-cup when in its normal position supported
beneath said opening, and a vertically sliding rod passing through the cover and
having a connection with the ink-cup, whereby said cup can be raised or lowered,
and a packing-ring surrounding the rod and when the cup is raised closes the
opening through which the rod passes, thereby making an air-tight joint, sub-
stantially as set forth.
