Complete Specification Left, 8th July, 1896-Accepted, 24th Oct., 1896
We, LA SOCIÉTÉ ANONYME DITE IMPRIMERIE ET LIBRAIRIE CENTRALES
DES CHEMINS DE FER (IMPRIMERIE CHAIX) of 20 Rue Bergère, Paris, in the
Republic of France, do hereby declare the nature of this invention to be as
follows:-
The use of two-cylinder printing presses called "retiration (or double-forme>
presses" is accompanied by the defect of maculation (or spotting).
The sheet of paper passes first between the first cylinder and forme to receive
the impression on one side, and then between the second cylinder and forme to
receive the impression on the other side. During the second printing, the already-
printed side of the paper is in contact with the second cylinder, upon which a
portion of the ink remains and smirches or "spots" the following sheets.
This serious defect remedied by us in the process which is the subject of this
invention.
Outside of the ordinary face-covering we wind a thin fabric such as madapollam
(calico) round the cylinder which is liable to be spotted and cover the fabric with
a coating of a mixture of vaseline, petroleum, and mineral oil, made in proportions
varying according to the temperature.
In summer or warm weather the mixture is formed as follows;-
In winter or cold weather the relative proportions should be ;-—
Vaseline
Petroleum
io kilogrammes.
4 litres.
Some other mineral-oil
2 litres.
The mixture of these ingredients may be effected in any appropriate manner;
but, by way of example the following process may be indicated ;--
The vaseline is melted and, in order to obtain a perfectly homogeneous mass, its..
temperature is raised to 55° Centigrade, then the petroleum is added to it and
afterwards the mineral oil. After having thoroughly stirred the mixture there is
poured into it from eight to ten grammes of perfume, for the purpose of masking
the smell of the petroleum. This perfume is composed of equal parts of the
essences of thyme and bitter almonds (mirbane).

page_text: The mixture may be applied to the tissue in any convenient manner, preferably,
directly thereon.
Dated this 30th day of October 1895.

Republic of France, do hereby declare the nature of this invention and in what 1
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :--
The use of two-cylinder printing presses called "retiration (or two-forme)
presses 18 accompanied by the defect of maculation (or spotting).
The sheet of paper passes first over the first cylinder to receive the impression 1
on one side, and then over the second cylinder to receive the impression on the
other side. During the second printing, the already-printed side of the paper is
in contact with the second cylinder, upon which a portion of the ink remains or
"sets off" and smirches or "
spots" the following sheets.
This serious defect is remedied by us in the process which is the subject of this 2
invention.
Outside of the ordinary face-covering we wind a thin fabric such as madapollam
(calico) round the cylinder which is liable to be spotted and cover the fabric with
à coating of a mixture of vaseline, petroleum, and mineral oil, made in proportions
varying according to the temperature.
In summer or warm weather the mixture is formed as follows:-
:-
Vaseline
Petroleum
Mineral oil
-
-
12 kilogrammes.
->
4 litres.
2 litres.
For the petroleum, any light petroleum oil or spirit, and for the mineral oil, any
heavier mineral oil, such as naphtha oil, may be employed.
In winter or cold weather the relative proportions should be :-
Vaseline
Petroleum
Mineral oil
10 kilogrammes.
-
4 litres.
-
2 litres.
The mixture of these ingredients may be effected in any appropriate manner :-
but, by way of example the following process may be indicated ;-
The vaseline is melted and, in order to obtain a perfectly homogeneous mass, its
temperature is raised to 55° Centigrade, then the petroleum is added to it and
afterwards the mineral oil. After having thoroughly stirred the mixture, there is
poured into it from eight to ten grammes of perfume, for the purpose of destroying
the smell of the petroleum. This perfume is composed of equal parts of the
essences of thyme and bitter almonds (mirbane).
The mixture may be applied to the fabric in any convenient manner, preferably,
directly thereon.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
In machine-printing, especially with "retiration" or two forme presses,.
encircling or covering the surface of the cylinder liable to become spotted, with
a thin fabric impregnated with a mixture of vaseline, petroleum, and other
mineral-oil, substantially as and for the purpose described.
