Year: 1866

page_text: LETTERS PATENT to Stephen Perry and Joseph John Perry, both of Red
Lion Square, in the County of Middlesex, for the Invention of "IMPROVE-
MENTS IN INKSTANDS OR VESSELS USED FOR CONTAINING AND SUPPLYING INK."
Sealed the 12th March 1867, and dated the 19th December 1866.
PROVISIONAL SPECIFICATION left by the said Stephen Perry and Joseph
John Perry at the Office of the Commissioners of Patents, with their
Petition on the 19th December 1866.
We, STEPHEN PERRY and JOSEPH JOHN PERRY, both of Red Lion Square,"
in the County of Middlesex, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN INESTANDS OR VESSELS USED FOR CONTAINING
AND SUPPLYING INx," to be as follows:-
In constructing inkstands or vessels for containing and supplying ink to
a dipping cup, which is situated above the highest level of the ink in the
stand or vessel which contains the supply of ink, we prefer in all cases that
they should be of glass, or earthenware, or china, or other material not
prejudicially acted on by ink, and we avoid as much as possible the use of
-metals. We construct the dipping cups as heretofere with tubes descending
to or near the bottom of the vessel, and where such descending tubes are of
glass or china we prefer to connect them with the dipping cup by vulcanized
ונם...מו

page_text: or cured india-rubber tubes. In somecases the descending tubes pass througl
the interior of the elastic and flexible stoppers hereafter described, whilst in
other cases the dipping cups and their descending tubesare separatefrom the
stoppers,and they have their separate openings to receive them at the upper
parts of the vessels containing the supply of ink.
The novelty of this Invention consists in the use of peculiarly formed
stoppers in combination with the dipping cups of inkstands or ink vessels,
and such stoppers are each to be of flexible and elastic vulcanized or cured
india-rubber formed hollow on the interior from the lower end upwards, but
closed at the upper end either by the passage of a descending tube of a
dipping cup passing through it, or by being made solid or otherwise closed at
the top, and when the descending tube of a dipping cup passes through a
stopper it is to be of comparatively small diameter as compared with the
interior of the stopper in order that the stopper may be raised and lowered
freely by reason of its giving way or collapsing. In each case whether the
descending tube passes through the stopper or it is at a distance or separate
therefrom, the stopper and the opening for receiving it is to be so formed
that the stopper shall not be capable of being pressed further inwards than
will cause the dipping cup to be supplied with the required quantity of ink
avoiding any excess. In some cases where the dipping cup is below the
level of the ink in the containing vessel, the stopper enters or closes an
opening below the dipping cup, the stopper in such caso having an opening
on one side corresponding with the hole at the bottom of the dipping cup so
as to allow the ink to flow when the stopper is moved, so as to bring the
opening on one side thereof to coincide with the hole in the dipping cup, and
this arrangement of stopper and opening in a vessel containing ink may be
used in conjunction with a pouring lip or spout or outlet at the upper part
of the containing vessel, or the pouring outlet or lip may be connected with
the stopper.
In some cases also the dipping cup may be formed with the stauran
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Stephen Perry and Joseph John Perry in the Great Seal
Patent Office on the 19th June 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, STEPHEN
PERRY and JOSEPH JOHN PERRY, both of Red Lion Square, in the County of 3
Middlesex, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of December, in the year of our Lord
One thousand eight hundred and sixty-six, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Stephen Perry and Joseph John Perry, Her special licence that we, the said
Stephen Perry and Joseph John Perry, our executors, administrators, and
assigns, or such others as we, the said Stephen Perry and Joseph John Perry,
our executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN INKSTANDS
OR VESSELS USED FOR CONTAINING AND SUPPLYING INK," upon the condition
(amongst others) that we, the said Stephen Perry and Joseph John Perry,
our executors or administrators, by an instrument in writing under our or
their hands and seals, or under the hand and seal of one of us or them, should
particularly 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 we, the said Stephen Perry and Joseph John
Perry, do hereby declare the nature of the said Invention, and in what
manner the same is to be performed, to be particularly described and
ascertained in and by the following statement thereof, that is to say:-
In constructing inkstands having dipping cups above the level of the ink in
the containing vessel we employ stoppers of vulcanized india-rubber, the
stopper is cylindrical on the exterior, and fits into a socket in the iuk vessel.
When the stopper is pushed down through the socket it compresses the air
in the vessel, and so causes the ink to rise into the cup; the stopper is made
hollow to render it sufficiently yielding to adapt itself to any irregularities in
the socket, and it has a flange at the top so that it may not be pushed in so
far as to cause the ink to overflow the cup..
Figure] isa transverse section of an earthenware inkstand thus constructed.
a is the ink reservoir; b, the dipping cup with its tube passi ng nearly to the
bottom of the reservoir a; c is the socket for the elasticand cylindrical stopper;
and d is the said stopper.
In some cases according to our Invention we arrange the dipping cup to
pass through the hollow elastic stopper.
Figure 2 shows a section of such an arrangement. a is the ink vessel which

page_text: in this case is represented as made of glass; a¹ is a socket at the upper part
thereof; and bis the dipping cup with its descending tube b¹ passing through
the stopper c.
Also according to our Invention we in some cases mould the.stopper and
dipping cup in one piece of vulcanized india-rubber, such an arrangement is
shown in section at Figure 3, where a is a glass iuk reservoir, and ba-stopper
with a dipping cup and descending tube moulded with it.
Also according to our Invention in some cases we connect the end of the
descending tube to the dipping cup by means of vulcanized india-rubber, so
that its end may remain at the bottom of the ink reservoir notwithstanding
the movement of the dipping cup.
Figure 4shows such an arrangement in section. a, a, is an ink vessel, here
represented as of glass, and 6 is the dipping cup of the same material passing
through the elastic stopper c; 6' is the tube descending from the cup b, and
connected with it by the coupling piece of vulcanized india-rubber tube b', or
the piece of tube 61 may be omitted, and the india-rubber tube 6 lengthened
to supply its place.
According to our Invention ininkstands acting on thebirdfountainprinciple,
or with dipping cups below the level of the ink in the containing vessel, we
employ similar hollow elastic stoppers; the stopper then is inserted into an
opening below the dipping cup, and it is cut away on one side, so that by
turning it round (or it may be by moving it a distance endways) the communi-
cation between the cup and the ink reservoir may be either opened or closed.
Figure 5 shows a section of such an arrangement. a, a, is the bird fountain
ink vessel a', the dipping cup thereon, and a2 thesocket into which the hollow
elastic stopper fits. When the stopper is in the position in which it is shown
in the Drawing the communication between the ink reservoir and the dipping
cup is open, and the inkstand ready for use, by turning the stopper half round
the communication is cut off, and the inkstand may safely be carried from
place to place without any special care.
Also according to cur Invention we combine hollow elastic stoppers with
openings at the side with bottles.or vessels for storing ink. The bottle or
vessel has a pouring spout on one side of the neck, and an air hole at the
other, and the stopper is cut away or perforated, so as in one position to leave
the passages free, and in another to close them liquid-tight. With bottles
or vessels thus arranged the stopper need not be withdrawn except to refill
the vessel.
Such an arrangement is shown in section at Figure 6. a, a, is an earthen-
ware bottle with a spout at a¹ and an air hole at c; bis the hollow elastic

page_text: stopper cut away to correspond with the spout a¹, and perforated opposite the
air hole a².
In some cases according to our Invention in place of providing the ink
bottle or vessel with a spout we form a passage through the stopper.
Figure 7 is a section of such an arrangement. a, a, is the glass ink bottle,
which may or may not have a screw thread moulded in its neck; b is a hollow
elastic stopper with a corresponding thread upon it, and having a flexible
delivery tube or nozzle b¹, by which the ink may conveniently be directed into
an inkstand which it is desired to fill. a' is an air hole in the side of the neck
of the bottle, and be a corresponding hole in the stopper, which may be brought
to correspond with the hole a' by partially unscrewing or turning the stopper.
It is preferred in all cases to form the vessels for containing ink of glass or
earthenware, but other materials may be used.
In witness whereof, wc, the said Stephen Perry and Joseph John Perry,
have hereunto set our hands and seals, this Seventeenth day of June,
in the year of our Lord One thousand eight hundred and sixty-seven.
STEPHEN PERRY.
