Improvements in the Manufacture of Ink.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention to be as follows:-
The object of my invention is to provide an ink preparation in solid, paste or
powder form,. from which fluid ink may be instantly produced when desired by
the addition of sufficient water to properly dissolve it. The peculiarity of my
preparation is the incorporation with or in the ink-producing compound or material
of one or more ingredients adapted to produce effervescence when the matter is
dissolved, so as to cause a thorough and complete admixture of all the elements
without the necessity of stirring or shaking. The ink is thus ready for immediate
use, and is of a uniform quality and color, without sediment, differing thus from
the product of ordinary ink powders or tablets which dissolve slowly, imperfectly
and after mechanical manipulation. By my improvement the coloring matter
is immediately diffused throughout the liquid, by reason of the effervescence.
My improved ink is preferably put up in the form of small tablets or thickened
disks, and consists of aniline of the desired color, or other ink-producing material,
with bicarbonate of sodium, or the like and with a suitable acid to produce an
effervescent action when the tablet is dissolved, such effervescence serving to
immediately diffuse the ink substance throughout the solution so that fluid ink
ready for use results. When the preparation is to be put up as a tablet, enough gum
arabic or saccharine matter is added to serve as a binder when the disks are com-
pressed.

page_text: 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: —
The object of my invention is to provide an ink preparation in solid, paste, or
powder form, from which fluid ink may be instantly produced, when desired, by
the addition of sufficient water to properly dissolve it.
The peculiarity of my preparation is the incorporation with or in the ink-pro-
ducing compound or material of one or more ingredients adapted to produce
effervescence when the matter is dissolved, so as to cause a thorough and complete
admixture of all the elements without the necessity of stirring or shaking. The
ink is thus ready for immediate use and is of a uniform quality and color without
sediment, differing thus from the product of ordinary ink-powders, which dissolve
slowly, imperfectly, and after mechanical manipulation.
By my improvement ink is preferably put up in the form of small tablets or
thickened discs and consists of anilin of the desired color or other ink-producing
material with bicarbonate of soda or the like and with a suitable acid to produce
an effervescent action when the tablet is dissolved, such effervescence serving to
immediately diffuse the ink substance throughout the solution, so that fluid ink
ready for use results.
When the preparation is to be put up as a tablet, enough gum-arabic or saccharine
matter is added to serve as a binder when the discs are compressed.
The drawing represents in perspective a series of ink-tablets made according
to my invention.
A suitable formula for about twelve tablets may be stated as follows; Nigrosene
or anilin, sixty grains; sodium bicarbonate, seventeen grains; tartaric acid, sixteen
grains; gum-arabic, twelve grains. Subdivide and compress.
I am aware that it is old to inclose an acid and an alkali, mechanically separated,
in the same package with sugar, either plain or medicated, for the purpose of
generating carbonic-acid gas as an element of the beverage or medicine to be
swallowed, thus providing for a portable soda water. I do not claim any such pre-
paration or practice.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is:-
1. An ink-producing compound in a dry form, in combination with an acid and
an alkali intermixed therewith, also in a dry form, and adapted to produce effer-
vescent action and liquid ink when the preparation is dissolved, substantially as
set forth.
2. An ink-producing compound in a non-liquid form, in combination with an
acid and an alkali intermixed therewith and adapted to produce effervescent action
and liquid ink when the preparation is dissolved, substantially as set forth.
3. A portable, dry, ink-compound in the form of compressed discs or tablets, the
same consisting of ink material proper in combination with an acid and an alkali
intermixed therewith and adapted to produce effervescent action and liquid ink
when the preparation is dissolved, substantially as set forth.
4. A portable, dry, ink-compound in the form of compressed discs or tablets con-
sisting of ink material proper, a suitable gum or saccharine binder, and an acid
and an alkali intermixed therewith and adapted to produce effervescent action and
liquid ink when the preparation is dissolved, substantially as set forth.
