Improvements in the Decoration of all kinds of Crêpés, Silks,
Leather, Skins, Hides, Bookbinders'-cloth, Leather-cloth, and
in the Apparatus for Producing the same.
ADOLPHE LOUIS KLEIN 12 Edenburgh Road, Angel Road Edmonton, in the
County of Middlesex, Engraver, do hereby declare the nature of this invention to be
as follows:-
The object of my Invention is to produce new effects of decoration upon all kinds
of Crêpés, Silks, Leather, Skins, Hides, Bookbinders-cloth, Leather-cloth, in a better
manner than heretofore. I use a rotary embossing machine, constructed with two, or
with three cylinders. The centre one is of metal and is engraved, the others are of
paper or cotton. I fix upon the frame of the embossing machine, arms and frames
with slides, for carrying the colour trough, furnisher, and transmitter rollers into
contact with the engraved metal cylinder, or with that of the paper or cotton cylinder,
by means of the main adjustment screws. In a machine constructed with two cylinders,
the engraved metal cylinder is the upper one, and the paper or cotton cylinder is the
lower one. The furnisher and transmitter rollers are arranged in sliding steps and
are regulated by adjustment screws, which work independent. The colour is delivered
upon the face of the engraved cylinder, or upon the raised face of the paper or cotton
cylinder as desired. The colour is waterproof, as is also, the colour composed of gold,
bronze, or other metallic powder. The novelty of the decoration consists in depositing
the gold, or other colour, at the bottom of the indented parts of the emboss upon the
materials. The better to understand the process, and the resulting novelty of
decoration is, (say) an imitation of crocodile skin, or morocco, is impressed upon
leather, at the same time the gold or colour is deposited at the bottom of the indenta-
tions made by the engraved cylinder upon the leather, in the manner aforesaid.
The scales, or raised parts of the crocodile skin, or the raised parts of the morocco,
are left their natural colour, that is the original colour of the leather, or of the other
materials, before the operation takes place.
The gold, or colour left in the said indentations, gives the raised parts more
prominence; and to the materials so decorated, a novel and brilliant effect. If so
desired, the indentations may be left the natural colour of the material, and the raised
parts may be covered with the gold or colour, or, two different colours may be used at
the same time, one for the indentations, and the other for the raised surface produced,
and further, the impression of the engraved cylinder may be taken upon the materials,
separately, and without the emboss; the same effects are produced upon all the
materials previously, and separately specified.
A further advantage is, that the said novelty of decoration can be produced with
rapidity, and cheapness, by this process.
In carrying out, my Invention, I use a rotary embossing machine, constructed
either with two, or with three cylinders, the upper and the lower cylinders may be
made of paper or cotton or other yielding substance. The centre cylinder is made of
metal, and is engraved with a suitable design or pattern upon it. When using a
machine constructed with two cylinders, the engraved metal cylinder is the upper one,
and the paper or cotton cylinder is the lower one. The design or pattern on the
engraved metal cylinder is impressed upon the face of the paper or cotton cylinder,
so that the reverse impression of the engraving on the metal cylinder stands out in
relief upon it. When using a machine constructed with three cylinders I impress
upon the face of both the upper and the lower paper or cotton cylinders the design or
pattern in a similar manner, as when using a machine constructed with two cylinders,
Las above described.

page_text: The metal engraved cylinder may be heated, or used cold, in accordance with the
kind of material to be operated upon. For all kinds of crêpés, silks, book-binders-
cloth, skins, leather, I prefer to use a machine constructed with two cylinders heat
being applied to the metal engraved cylinder, and for hides, and leather-cloth, I prefer
to use a machine constructed with three cylinders, the centre metal engraved cylinder
may be heated, if so required. The materials to be decorated, are passed between the
metal engraved cylinder, and the paper or cotton cylinder, and it receives the emboss.
of the pattern, and the colour, (at the same time) by which the cylinder, or cylinders,
have been previously furnished, producing new effects of decoration upon the materials,
before specified.
'
When the raised part of the material is required to be coloured, bronzed or silvered,
the paper, or cotton cylinder is furnished on the surface of the raised parts, which is a
reverse impression of the metal engraved cylinder, the engraving upon the said metal
cylinder being indented.
When using a machine constructed with three cylinders, I raise the upper cylinder,
just sufficient out of the engraved cylinder, so that it will carry the colour it has
received, into the indented parts of the engraving, without crushing it out. The
metal engraved cylinder deposits the colour it thus receives, upon the raised parts of
the pattern of the material, leaving the indented parts of the material, the natural
colour of the material, before being operated upon.
When the indented parts of the pattern, on the material are required to be coloured,
or. bronzed, I furnish in a like manner the face of the engraved cylinder, this carries
the colour into the indented parts of the pattern on the material, leaving the surface,
or raised part of the material, its natural colour, or the colour of the material, previous
to being operated upon. When two colours are required upon the material, one on
the raised parts, and the other in the indented parts, I use two sets of furnishers, one
set, furnish the face of the paper, or cotton cylinder with colour, and the other, set,
furnish the engraved cylinder with colour.
.
The two colours are thus deposited into their respective positions upon the material,
simultaneously.
If I wish to take the impression of the engraving on the metal cylinder upon silk,
or other material, without taking the emboss at the same time, I raise the engraved
cylinder from the paper or cotton cylinder, and cover the said paper or cotton
cylinder with a web of india rubber or other soft woven fabric so that it will present
a plain, smooth, soft, surface to the engraved cylinder, and also protects the raised
parts on the paper or cotton cylinder from injury, under the pressure put upon it. I
supply the engraved cylinder with colour direct from the furnisher in the colour
trough, elevating the transmitter roller or a knife to a point above the furnisher,
pressing it against the face of the engraved cylinder, by means of the adjustment
screws, so that it will clear away any excess of colour which it may receive from the
engraved cylinder, while the said cylinder is being furnished, with the colour. Pitch
pins are placed upon each end of the engraved cylinder, and, also their reverse, are
upon the paper or cotton cylinders, when these are brought together, they insure the
metal engraved cylinder going back again into the exact part of the pattern, from
which it was raised, to allow the india rubber, or other web, to be put upon the paper
or cotton cylinder, before said. The arrangement by, which I supply the colour, or
colours, to the engraved cylinder, and to the paper or cotton cylinder, is by fixing
upon the frame of the embossing machine, two arms opposite to, and parallel with
each other, fit with slides and screws, these I call the main slides, and screws, to
these are arranged other frames which can be moved backward, and forward, upon
the slides by means of the main screws. The purpose of this frame is to, carry. the
colour trough, furnisher, and transmitter roller, or rollers, the said frame is constructed
with sliding steps and adjustment screws for regulating and controlling the rollers
aforesaid and the colour trough, each sliding step is controlled by its own adjust-
ment screw, and can be moved backward, or. forward, independent of each other.
The rollers which are in the colour trough are fit into the sliding steps, and can be
adjusted to any angle or position necessary, and also insure bringing the, rollers into

page_text: proper position, one with the other, also for regulating the pressure, against each
other. The main slides and screws, move the said rollers and the colour trough
simultaneous in or out of contact with the engraved cylinder, or, that of the paper
or cotton cylinder, as desired. The furnisher roller revolves in the colour trough
and may be covered with composition, or vulcanized india rubber to resist heat, in
contact with this roller is placed a small metal roller, in sliding steps, and controlled
by adjustment screws, this roller does not revolve but is pressed upon the face of
the roller in the colour trough by the adjustment screws, and is used to regulate the
quantity of colour taken upon the face of the furnisher roller out of the colour trough.
The roller with which the furnisher is put into contact, I call the transmitter roller,
this roller may be made in the same manner, and of the same substance, as the
furnisher roller. I prefer to use a roller of vulcanized india rubber when the engraved
cylinder is heated. The transmitter roller is put into contact with the furnisher
roller, by the said adjustment scrows, against the transmitter roller, revolves a small
metal roller, similar to the metal roller against the aforesaid furnisher roller regulated
by the adjustment screws. All the rollers and the colour are moved into their
proper position, by means of the main adjustment screws. The colour is delivered
by the transmitter roller upon the face of the engraved metal cylinder, or upon the
face of the pattern in relief, on the paper or cotton cylinder. In some decorations,
I furnish the colour direct from the farnisher roller to the engraved cylinder, or to
the paper or cotton cylinder, without using the transmitter roller.
The colours used are waterproof and are composed of 2 parts gold size, 1 part
raw linseed oil, 1 part turpentine 32nd part driers, add pigment to the required
consistence, grind all together. The bronze or other metallic powder, fixing compo-
sition, is 2 parts gold size, part raw linseed oil, part turpentine, ground
together with sufficient Persian red to the consistency required, when using this
colour I let it become tacky before I put the bronze or other metallic powders upon
the materials.
The metallic colour is composed of; 2 lbs. of best glue, 2 gallons of skimed milk,
2 oz. albumen, 2 oz. unslacked lime, boiled together, when cool I add the metallic
powder, and furnish with it direct to the engraved cylinder, or to the paper or
cotton cylinder, as before described.

other frames which can be moved backward and forward upon the slides by means of
the main screws as shown in drawing Fig. 2. by J and 1. The purpose of this frame
is to carry the colour trough, H. furnisher, and transmitter roller, or rollers, E and F.
in Figs. 2 and 3. the said frame is constructed with sliding steps and adjustment
screws for regulating and controlling the rollers aforesaid; and the, colour trough ;
each sliding step is controlled by its own adjustment screw, as shown in Fig. 2. E. F.
and G. and can be moved backward or forward independent of each other. The
rollers which are in the colour trough are fit into the sliding steps and can be adjusted
to any angle or position necessary, and also insure, bringing the, rollers into. proper
position, one with the other also for regulating the pressure, against each other. The
main slides and screws, shown in Fig. 2 by J. move the said rollers and the colour
trough simultaneous in or out of contact with the. engraved cylinder, or that of the
paper or cotton cylinder as desired.
The furnisher roller revolves in the colour trough, H. Figs. 2 and 3. and may. be
covered with composition, or vulcanized india-rubber to resist heat; in contact with
this roller is placed a small metal roller in sliding steps, and controlled by adjustment
screws, G. in Fig. 2. this roller does not revolve, it is held rigid. by set screws, K. in
Figs. 2 and 3. but is pressed upon the face of the roller in the colour, trough by, the
adjustment screws, G. in Fig. 2. and is used to regulate the quantity of colour. taken
upon the face of the furnisher roller out of the colour trough. The roller E. in Fig. 3.
with which the furnisher is put into contact I call the transmitter roller; this. roller
may be made in the same manner and of the same substance as the furnisher roller, F.
in Fig. 3. I prefer to use a roller of vulcanized india-rubber. when. the. engraved
cylinder is heated. The transmitter roller is put into contact. with the furnisher
roller by the said adjustment screws. All the rollers and the colour, are moved. into
their proper position by means of the main adjustment screws, shown by. L in Figs. 2
and 3. The colour is delivered by the transmitter roller upon the face of the engraved
metal cylinder or upon the face of the pattern in relief, on the paper, or cotton
cylinder. In some decorations, I furnish the colour direct from the furnisher roller
to the engraved cylinder, or to the paper or cotton cylinder without using the

page_text: transmitter roller. The colours are waterproof and are composed of 2 parts gold size
1 part raw linseed oil, 1 part turpentine, 32nd part driers, add pigment to the required
consistence, grind all together. The bronze or other metallic powder, fixing compo-
sition is 2 parts gold size, part raw linseed oil part turpentine, ground together
with sufficient Persian red, to the consistence required, when using this colour I let
it become tackey before I put the bronze or other metallic powders upon the
materials..
The metallic colour is composed of 2 lbs. of best glue, 2 gallons of skimed milk 2 oz.
albumen, 2 oz. unslacked lime, boiled together, when cool I add the metallic powder,
and furnish with it direct to the engraved cylinder or to the paper or cotton cylinder,
as before described. For decorating silk, crêpes, and leather, I prefer to take the
emboss: upon the material in the manner before described, I keep the material tight
upon the paper or cotton cylinder after it has received the impression upon it from the
engraved cylinder, the paper or cotton cylinder carries the material round with it;
while the material is still embedded in the indented parts of the paper or cotton
cylinder which has been produced by the embossing of the materials aforesaid. I
furnish the face of the material thus presented with the colour, while it is in this
position either direct from the furnisher roller as aforesaid, or with the transmitter
roller, thus furnishing the colour to the raised parts so made upon the material as it
is being carried round by the paper or cotton cylinder as illustrated in the accom-
panying drawing, the said drawings, show at the same time the manner by which
the said engraved paper or cotton cylinders are also furnished, as before specified, in
Fig. 1.

lower cylinder, as is found the most convenient; In a machine constructed with two
cylinders the material is carried round the lower paper, or cotton cylinder in a
similar manner to that which is done with a machine constructed with three cylinders.

claim is :
:
1. Furnishing the face of the engraved cylinder, or the paper or cotton cylinders of
the embossing machine, with colour, or colours, substantially as before described.
2. The particular arrangement of the furnisher roller; transmitter roller; and
colour regulating roller; acting either separately, or both together, for furnishing
