PROVISIONAL SPECIFICATION left by the said Fortuné Francois Benvenuti
at the Office of the Commissioners of Patents on the 17th May 1882.
FORTUNE FRANCOIS BENVENUTI, of Swansea, in the County of Glamorgan,
Professor of Languages, Literature and Philosophy, "IMPROVEMENTS IN THE
CONSTRUCTION OF FOUNTAIN INKSTANDS,"
This Invention consists of improvements in the construction of fountain
inkstands, whereby the supply of ink from the reservoir to the dip cup can be
regulated in a simple and efficacious manner.
The ink reservoir, which is constructed of any suitable form or size, is made of
ebonite, earthenware, glass or other desired material, and has formed in the lower
part thereof an aperture, which leads into a duct or channel, the continuation of
which is arranged within a suitable stem or other contrivance and opens into the
lower part of the dip cup, the upper part of which is level, or nearly so, with a
horizontal partition arranged across the upper part of the reservoir, near the top
thereof. In the centre of the said partition is made an aperture for the purpose
hereinafter referred to. The lid of the said reservoir is formed of ebonite, metal or
other suitable material, the upper part thereof, being, by preference, of a dome like
form. Through the upper part of the lid is formed an aperture having a screw
thread therein, and into this aperture screws a small bolt or bar the lower part of
which, that is to say, the end projecting within the space enclosed between the lid
and the before mentioned horizontal plate, has fitted thereon a stud or similar
contrivance. A pear shaped vessel, hereinafter referred to as the pneumatometer,
is formed of vulcanite or other suitable elastic material which is impervious to air
and has an aperture formed in the lower part of the neck, and it is arranged
within the space enclosed between the lid and the horizontal partition in the
following manner. The neck of the said pneumatometer is passed through the
Din S

page_text: hole in the horizontal partition until a circular washer or ridge arranged, or formed,
on the exterior of the pneumatometer rests upon the upper part of the partition
and closes the hole therein in an air tight manner, and when in this position the
upper part of the said pneumatometer bears against the stud on the before
mentioned screw bolt. Around the pneumatometer is arranged a damper composed
of flannel, an aperture being formed in the top thereof at the point on which the
said stud acts on the vessel.
The lid may be arranged to fit the upper part of the reservoir by the following
means. Two projecting studs are arranged on the interior of the lid and are caused
to pass down grooves formed on the exterior of the upper part of the reservoir, at
the lower end of such grooves, are formed similar grooves at right angles, so that
by turning the lid the projecting studs are caused to enter the last mentioned
grooves.
The dip cup may be provided with a cover of any suitable design and
construction.
When it is desired to employ the inkstand hereinbefore described, ink is poured
into the reservoir until it rises to the orifice in the lower part of the dip cup, when
having first soaked the damper of the pneumatometer, the lower end of which will
be above the level of the ink, the pncumatometer and the lid are then placed into
position. When it is desired to fill the dip cup with ink, the pneumatometer is
compressed by screwing down the before mentioned stud, thereby forcing a further
supply of air between the surface of the ink and the upper part of the reservoir
thus causing a certain amount of ink to flow through the said duct or channel into
the dip cup.
In some cases, when the ink in the dip cup is exhausted, it will be
found convenient to unscrew the bolt and then to screw it down again, by which
means the said dip cup is refilled, and this is repeated until the ink is completely
exhausted in the reservoir.
It will be readily understood that inkstands constructed as hereinbefore
described, can be formed double, so that they can contain inks of different natures.

FORTUNE FRANÇOIS BENVENUTI, of Swansea, in the County of Glamorgan
Professor of Languages, Literature and Philosophy, "IMPROVEMENTS IN THE
CONSTRUCTION OF FOUNTAIN INKSTANDS,"
My said Invention consists of improvements in the construction of fountain ink
stands whereby the supply of ink from the reservoir to the dip cup can be
regulated in a simple and efficacious manner.
The ink reservoir, which is constructed of any suitable form or size, is made of
ebonite, earthenware, glass or other desired material, and has formed in the lower
part thereof an aperture, which leads into a duct or channel, the continuation of
which is arranged within a suitable stem or other contrivance and opens into the
lower part of the dip cup. The upper part of the dip cup is level, or nearly so,.
with a horizontal partition arranged across the upper part of the reservoir, near the
top thereof.
In the centre of the said partition is made an aperture for the
purpose hereinafter referred to. The lid of the said reservoir is formed of ebonite,
metal or other suitable material, the upper part thereof, being, by preference, of a
dome like form. Through the upper part of the lid is formed an aperture having
a screw thread therein, and into this aperture screws a small bolt or bar the lower
part of which, that is to say, the end projecting within the space enclosed between
the lid and the before mentioned horizontal plate, has fitted thereon a stud or
similar contrivance. A pear shaped vessel, hereinafter referred to as the "
pneu-
matometer," is formed of vulcanite or other suitable elastic material which is
impervious to air and has an aperture formed in the lower part of the neck. The
said pneumatometer" is arranged within the space enclosed between the lid
and the horizontal partition in the following manner. The neck of the said
"pneumatometer" is passed through the hole in the horizontal partition until a
circular washer or ridge arranged, or formed, on the exterior of the pneumato-
meter rests upon the upper part of the partition and closes the hole therein
in an air tight manner, and when in this position the upper part of the said
"pneumatometer" bears against the stud on the before mentioned screw bolt.
Around the "pneumatometer" is arranged a damper composed of flannel, an
aperture being formed in the top thereof at the point on which the said stud acts
on the vessel.
The lid may be arranged to fit the upper part of the reservoir by the following
means. Two projecting studs are arranged on the interior of the lid and are
caused to pass down grooves formed on the exterior of the upper part of the
reservoir, at the lower end of such grooves, are formed similar grooves at right
angles, so that by turning the lid the projecting studs are caused to enter the last
mentioned grooves.
I will now proceed to refer to the accompanying drawings from which the
nature of my said Invention will be more clearly understood; A. is the ink
reservoir and a. is the aperture in the lower part thereof for conducting the ink to
the duct or channel a¹. B. is the dip cup. C. is a partition arranged across the
ink reservoir, and c. is the aperture in the centre thereof. D. is the lid of the
reservoir and d. is the bolt or bar screwing into the same. E. is the "pneumato-
meter" and c. is the neck thereof, e'. is the circular washer or ridge thereon Fis
the damper arranged around the "pneumatometer."
The dip cup may be provided with a cover of any suitable design and
construction.

When it is desired to employ the ink stand hereinbefore described, ink is poured
into the reservoir A until it rises to the orifice in the lower part of the dip cup B.
when having first soaked the damper F. of the "pneumatometer " E. the lower end
of which will be above the level of the ink, the "pneumatometer" and the lid
are placed into position. When it is desired to fill the dip cup with ink the
'pneumatometer" is compressed by screwing down the before mentioned bolt or
bar d thereby forcing a further supply of air between the surface of the ink and
the upper part of the reservoir thus causing a certain amount of ink to flow
through the said duct or channel into the dip cup. In some cases, when the ink
in the dip cup is exhausted, it will be found convenient to unscrew the bolt and
then to screw it down again, by which means the said dip cup is refilled and this
is repeated until the ink is completely exhausted in the reservoir.
It will be readily understood that ink stands constructed as herein before
described, can be formed double, so that they can contain inks of different natures.
Having thus described and ascertained the nature of the said Invention and the
manner in which it 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 hereinbefore in part recited Letters Patent, is:-
The improvements in the construction of fountain ink stands, substantially as,
and for the purposes, herein before set forth and described.
In witness whereof I the said Fortuné François Benvenuti have hereunto set
my hand and seal this fifteenth day of November in the year of our Lord
