ALEXANDER DEY M.A. Nithsdale Drive Pollockshields Glasgow one of H.M.
Inspectors of Schools do hereby declare the nature of this invention to be as
follows:-
The object of this Invention is to provide a better means of regulating the supply or
flow of Ink so as to allow of the pen receiving only a proper quantity of Ink when it
is dipped into the holder and for preserving the Ink from dust &c.
According to this my Invention I construct of glass metal earthenware or other
suitable material a chamber to contain a considerable quantity of Ink. On the inside
of this chamber is formed a screw thread to receive a piece having a corresponding
thread. A small cavity is made either on top of screw piece or on side of chamber,
communicating with inside of chamber by means of a core or small opening. When
piece is screwed into chamber it will press the ink, and cause it to flow up this core or
opening into the cavity from whence it can be used by a pen in the ordinary way.
To keep the supply of ink at the desired height in the cavity it is only necessary to
screw the piece a little further into the chamber from time to time, and by withdrawing
the screw piece slightly, the ink will fall back again into the chamber. By constructing
a series of chambers & screw pieces these improved Ink bottles can be made so as to
contain all the different kinds of ink say Common Copying & Red.

I, ALEXANDER DEY, Pollokshields Glasgow Scotland, one of H.M. Inspectors of
Schools for Scotland 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 :-
My invention consists of a cubical block of glass or other material hollowed out
into a cup. The hollow is cylindrical and has little or no taper and leaves a thickness
of a quarter of an inch or so for bottom. The hollow has a groove running round it
from top to bottom forming it into what is ordinarily called a female screw.
A plug
or male screw of glass or other material is made to fit the female screw and is capable
of being screwed down to the bottom of the female screw. This plug is about one inch
in thickness or depth and has a small hole through its centre tapering downwards.
Suppose the hollow in the cubical block to be two inches in depth and to be half filled
with ink. Let the plug now be inserted and screwed down, the ink will be forced
up the hole in its centre and form there a little well into which the pen may be dipped.
This little well can be kept at a nearly uniform depth by a slight turn of the plug
backward or forward. The pen can thus be dipped to the bottom of the well every
time, the plug being slowly screwed down till all the ink is forced out of the bottle.
The sediment drops to the bottom and never clogs the point of the pen. The penholder
is never dirty and consequently the fingers never get stained.
The plug may be moved by a small pin inserted in the glass or by a small hole into
which the point of the pen may be inserted.
As an alternative method the little hole into which the ink is forced up may be in
the edge of the block or cup. In this case the plug would be solid and as long as the
cup is deep. Moreover in this second case the plug itself may be a cup into which
another plug may be screwed forming another compartment for holding ink of a different
colour.
It is evident that the thread either on the male or female screw need not be
continuous and that the dimensions of the cup and plug may be varied at pleasure. The
outside of the cup may have any form.
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
ね。
This particular method for forcing up the ink and keeping it at a nearly uniform
depth in the little well as hereinbefore described.
