Improvements in Ink Wells.
We, SAMUEL HENRY BOYDEN, Commercial Traveller, and Messrs. COOPER,
DENNISON AND WALKDEN LIMITED both of 7 St. Bride Street, in the City of
London, Ink Manufacturers, do hereby declare the nature of this invention to be
as follows:-
This invention relates to that class of ink wells in which a tube, usually of glass.
dips into the ink, being generally supported by an indiarubber diaphragm. As at
present constructed the diaphragms and tubes are costly and being exposed, the
diaphragm is liable to be pricked by the pen and consequently damaged, in which
case the replacing is expensive, and troublesome., Also, the glass tubes as at
present made are very thin and easily broken. By our present invention these
difficulties are got over. In carrying out the improved invention we employ any
suitable ink well of glass or other material and upon this we place a cap or
diaphragm preferably of rubber either moulded to the proper shape or merely a
Hat piece secured in any desired manner to the top of the ink well which is
preferably provided with a wide mouth a convenient way of fixing it being to
place a metal or other ring around the edge of the cap which may advantageously
be circular, the ring if necessary covering a portion of the cap. By preference
the rubber cap is made of relatively large diameter and is provided with a central
orifice through which is placed the dipping tube which may be made of any suitable
material but preferably of glass, thick and strong, and with the necessary hole
through the middle, the tube dipping into the ink in the usual manner. All these
parts may be ornamented in any desired manner. The tube may be tapered
either inside or outside or both and may be provided with an enlarged head
to' fit over the rubber' diaphragm and may also if desired have a grooved neck
in which the diaphragm would lie when the tube is passed through the
diaphragm.
The operation of this invention would be similar to that of the
the ordinary ink
wells of this description, but it will be readily appreciated that owing to the
strength and construction of the parts they are not likely to be broken and can
be immediately replaced if they are broken, while the cost of any single piece is
very slight. The enlarged head of the dipping tube serves to cover over and protect
the rubber diaphragm.

Improvements in' Ink Wells.
We, SAMUEL HENRY BOYDEN, Commercial Traveller, and Messrs. COOPER,
DENNISON & WALKDEN LIMITED, of 7 St. Bride Street in the City of London,
Ink Manufacturers; 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 that class of ink-wells in which a tube, usually of glass,

page_text: dips into the ink, being generally supported by an india rubber diaphragm. As at
present constructed the diaphragms and tubes are costly, and being exposed, the
diaphragm is liable to be pricked by the pen, and consequently damaged, in which
case the replacing is expensive and troublesome. Also, the glass tubes as at present
made are very thin and easily broken. By our present invention these difficulties
are got over. In carrying out our invention, as illustrated in the accompanying
drawing, which represents one of the devices in section, we employ any suitable
ink-well A of glass or other material and upon this we place a cap or diaphragm B
preferably of indiarubber either moulded to the proper shape or merely a flat
piece secured in any desired manner to the top of the ink well A, which is
preferably provided with a wide mouth, a convenient way of fixing it being, as
shown in the drawing, to place a metal or other ring or band C around the edge
of the cap B which may advantageously be circular the ring if necessary covering
a portion of the cap. This ring may readily be removed to admit of the diaphragm B
and dipping tube D being detached from the ink-well for cleaning, filling or other
purposes. By preference the rubber cap B is made of relatively large diameter
and is provided with a central orifice through which is placed the dipping tube D
which may be made of any suitable material, but preferably of glass, thick and
strong, and with the necessary hole D' through the middle, the tube dipping into
the ink in the usual manner. All these parts may be ornamented in any desired
mauner. The tube D may be tapered either inside or outside, or, as illustrated in
the drawing, both inside and outside, and have an enlarged head D2 to fit over the
rubber diaphragm B and a grooved neck D³ in which the diaphragın B would
lie when the tube D is passed through the diaphragm.
The operation of this invention is similar to that of the ordinary ink-wells of this
description, but it will be appreciated that, owing to the strength and construction
of the parts they are not likely to be broken, and can be immediately replaced if
they are broken, while the cost of any single piece is very slight. The enlarged
head D2 of the dipping tube D serves to cover over and protect the rubber
diaphragm B. The head D2 need not be of the same material or piece as the
tube D.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what
we claim is ;-
1. The combination with an ink-well a separate dipping tube and a flexible
diaphragm or cap connecting these two parts together of a removable ring or band
such as C for securing the diaphragm to the ink-well substantially as described
and illustrated in the accompanying drawing.
2. The combination with an ink well and a flexible diaphragm or cap of a dipping
tube such as D having a head or enlargement D2 to cover and protect the cap
substantially as described and illustrated in the accompanying drawing.
3. The combination with an ink well and a flexible diaphragm of a dipping tube
such as D having a head or enlargement D2 and annular groove D³ substantially as
described and illustrated in the accompanying drawing.
4. The combination and arrangement of parts constituting the complete ink-well
substantially as described and illustrated in the accompanying drawing.
