An Improved Ink for Printing and similar purposes.
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 and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention relates to an improved ink for printing and similar purposes.
According to the said invention I first form a composition consisting of
petroleum which has been volatilized until a residuum of its wax has been
procured in consistency similar to the product known as "vaseline" with equal
parts of some fatty substances-such as refined linseed-oil in its oxidized state which
I form or compound as follows:
1 superheat forty gallons of a refined quality of linseed-oil with an equal quantity,
by weight, of the following articles: dried and crystallized sulphate of zinc, litharge,
red lead, and binoxide of manganese, of each seven pounds, all aqueous and fatty
substances being removed from the oil by this process, an equal mixture of these
ingredients blended in a vat can be ground with all mineral or vegetable colors or
pigments.
To form my improved ink this mixture is to be ground or dissolved with the
pigments in proportion to the strength of the color desired or the nature or class of
pigment used, forming a solid jelly or concentrated ink. The ink thus formed is
non-evaporating to a remarkable degree and will not clog or harden on ordinary
roller-composition or any non-fibrous material. Friction caused by propelling the
roller over the same, will, at all times, without the admixture of other ingredients,
reduce the same to the desired consistency, which is not, so far as I am aware,
possible with any known make of ink for use in connection with stencil, ribbon, pads,
or similar reproducing processes or appliances by pressure or otherwise, with or
without the roller process.
I form a reduced or jelly compound by adding to my mixture, as compounded
above, of the balsam of fir one per cent., pure linseed-oil ten per cent., and benzine,
to be added in their respective order as soon as the one previously added has been
heated to 210° Fahrenheit and has become fully assimilated. The benzine is to be
added only after the compound has been cooled. When so reduced and prepared they
form a concentrated or compressed printing-ink, which will require no adimixture of
other ingredients to reduce the same to the desired consistency for stencil or general
printing purposes. It will not cake or harden on ordinary roller compositious; it
will not precipitate; it will not spread or flow when printed, and can not leak or spill
from the packages, and will not be effected by hot or cold temperatures, and will work
equally well in all climates, whether dry or humid, and moreover it will not tack or
tear the stencil, as it is practically non-adhesive.
Having now particularly described and ascertained the nature of the 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:
First. A stiff, concentrated, or condensed ink consisting of vaseline combined with a
fatty substance and coloring-matter, substantially as herein described.
Second. A stiff, concentrated, or condensed ink composed, essentially, of vaseline,

page_text: linseed-oil, and coloring-matter, forming a jelly-like compound, which is rendered
limpid by friction without the admixture of fluid matter, substantially as herein
described.
