LETTERS PATENT to John Piddington, of 53, Gracechurch Street, in the
City of London, for the Invention of "IMPROVEMENTS IN INKSTANDS."-
A communication from abroad by George Marie Stoltz, junior, residing,
at 52, Rue Fontaine Saint Georges, Paris, in the Empire of France,
Engineer.
Sealed the 27th August 1867, and dated the 28th February 1867.
PROVISIONAL SPECIFICATION. left by the said John Piddington at the
Office of the Commissioners of Patents, with his Petition, on the 28th
February 1867.
I, JOHN PIDDINGTON, of 53, Gracechurch Street, in the City of London,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN,
INKSTANDS," being a communication to me from abroad. by George Marie
Stoltz, junior, residing at 52, Rue Fontaine Saint Georges, Paris, in the,
Empire of France, Engineer, to be as follows:-
This Invention consists. in certain improvements in inkstands, whereby
important advantages are attained, combined with great simplicity of con-
struction.

page_text: The ink is contained in a holder or reservoir formed of any suitable
material, a disc being placed within the same, and furnished with a series of
cups formed in or attached thereto. The disc is capable of being set in motion
and of being revolved by a knob or head placed at the end of a rod or stem
which is attached to the disc and passes through the side of the holder or
reservoir, in which it is rendered air-tight by means of elastic washers, or in
any other suitable manner; such arrangement also serving to keep the disc
steady by bringing a projection formed on the rod or stem into notches pro-
vided in the neck or aperture in the side of the holder or reservoir through
which it works, The disc is placed a little above the bottom of the holder or
reservoir, so that upon its being turned by means of the knob or head the
cups, which are funnel shaped and more open towards.the circumference of
the disc than towards the axis thereof, will raise nearly the whole contents of
the holder or reservoir without disturbing the sediment or other substances
deposited by the ink. By causing the disc to revolve in one direction the
cups become filled and raise the ink towards an opening provided in the lid
of the holder or reservoir, whilst by turning the disc in the opposite direction
the unused ink will be emptied back into the holder or reservoir. If four
cups are affixed to the disc at equal distances from each other one will
correspond with the.opening at each quarter, of a revolution, and at, each half
quarter of a revolution the orifice may be closed by the solid portion of the
circumference of the disc..
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Piddington in the Great Seal Patent Office on the
28th August 1867,
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
PIDDINGTON, of 58, Gracechurch Street, in the City of London, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of February, in the year of our
Lord One thousand eight hundred and sixty-seven, in the thirtieth of
Her reign, did, for Herself. Her heirs and successors, give and grant unto

use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IMPROVE-
KENTS IN INKSTANDS," being a communication to me from abroad by George
Marie Stoltz, junior, residing at 52, Rue Fontaine Saint Georges, Paris, in the
Empire of France, Engineer, upon the condition (amongst others) that I, the
said John Piddington, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should par-
ticularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to be
filed in the Great Seal Patent Office within six calendar months next. and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Piddington, do hereby declare
the nature of the said Invention, and in what manner the same is to be per
formed, to be particularly described and ascertained in and by the following
statement, reference being had to the Drawings hereunto annexed, and to the
figures and letters marked thereon, that is to say
The object of the said Invention is to remedy some important defects. which
are connected with all inkstands as hitherto constructed, by the introduction
of one combining convenience in use and simplicity of manufacture... By this
improved system all contact with the external air is avoided, thereby pre-
serving the ink from deterioration, it may be shaken before being used, or it
may
be allowed to remain undisturbed and be raised when required for use
entirely free from deposit or foreign substances, and the quantity of ink may
vary as required without any danger of its being spilled, even whilst being
poured into the holder or receptacle which contains it. The mechanical
arrangements adopted for these purposes are extremely simple, durable, and
easy to use.
:
The ink is contained in a holder or reservoir formed of metal, glass;
porcelain, or of any other suitable material, a disc being placed within the
same, such disc being furnished with a series of cups formed therein or
attached thereto. The disc is capable of being set in motion and of being
rotated by a knob or head placed at the end of a rod or stem which is attached
to the disc and passes through the side of the holder or reservoir, in which it
is rendered air-tight by means of elastic washers, or in any other suitable
manner; such arrangement also serving to keep the disc steady by bringing
a projection which is formed on the rod or stem into notches provided in the

page_text: neck or aperture in the side of the holder or reservoir, through which it
works. The disc is placed so that upon its being rotated the periphery
thereof shall be a little above the bottom of the holder or reservoir, and upon
its being turned by means of the knob or head the cups, which are funnel
shaped and more open towards the circumference of the disc than towards
the axis thereof, will raise nearly the whole of the contents of the holder or
reservoir without disturbing the sediment or other substances which may
have been deposited by the ink. By causing the disc to revolve in one
direction the cups become filled and raise the ink towards the opening pro-
vided in the lid of the holder or reservoir, whilst by turning the disc in the
opposite direction the unused ink, will be emptied back into the holder or
reservoir. If. four cups are affixed to the disc at equal distances from each
other one will correspond with the opening at each quarter of a revolution;
and at each half quarter of a revolution the orifice may be closed by the solid
portion of the circumference of the disc.
C
I will now proceed to describe the accompanying Drawings, from which
the nature of the Invention will be more clearly understood.
I'
Figure 1 is a section of the inkstand through the line E, F, of Figure 2.;
Figure 2 is a vertical section through the line C, D, of Figure 1; Figure 3
is a plan, and Figure 4 a horizontal section along the line A, B, of Figure 1.
The same letters of reference are used for similar parts in the several
Figures.
b is the holder or reservoir within which is the moveable disc a furnished
with the cups h, h, h, h, which raise the ink towards the opening d in the lid
or cover c. It will be observed that the cups are funnel shaped, being more
open towards the circumference of the disc a than towards the axis thereof,
so that when they are in a vertical position the liquid taken up by the width
of the cups siuks to the bottom thereof, presenting sufficient depth for use.
The disc a is set in motion by the knob or head of the rod or stem e screwed
into the disc a at the point k, and rendered air-tight in the holder or reservoir
b by means of the elastic india-rubber washers j, j, which also serve to keep
the disc steady by bringing the projection f into the notches g, arranged so as
to keep it open or shut. Another washer i placed between the disc a and
the cover c renders it if required perfectly air-tight..

Having thus described and particularly ascertained the nature of the
Invention, and in what manner the same is to be performed, I would observe
in conclusion that what I consider novel and original, and therefore claim as
constituting the Invention secured to me by the said herein before in part

page_text: recited Letters Patent is, the construction of inkstands, as substantially herein-
before described and set forth, or any mere modifications thereof.
In witness whereof, I, the said John Piddington, have hereunto set my
hand and seal, this Twenty-seventh day of August, in the year of our
Lord One thousand eight hundred and sixty-seven.
Witness,
A. CROOŸ.
