Improvements relating to Colour-printing, and to Apparatus
therefor.
I, JEAN BACHELERIE, of 50, Rue des Boulets, Paris, in the Republic of France,
Manufacturers do hereby declare the nature of this invention to be as follows :—~
My invention relates to a new system of printing in several colours, the said
printing being effected at one impression or operation by means of a sheet of felt
acting in a similar manner to a wet stomp.
This process is applicable for the multiple colour-printing of engravings,
drawings, typographic impressions, either printed directly with all their colours or
previously printed, or with a single tint, black or the like:
The process is also applicable for producing upon the already coloured sheet a
superposition of tints giving it the final or finishing; shades.
For this purpose, the arrangement of the colours which are to be applied upon
the sheet being known, I cut out of a sheet of felt, cloth or other material capable
of receiving or holding the colour, such as powdered cork, the outlines of each
part which is to be of the same colour throughout and after having, saturated the
various pieces of felt. with the proper colours l'unite them to form an inking
plate which presents all the colours: at the places where they are required.
The various colour-receptacles thus formed can if required be separated by strips
to prevent the colours from running into one another.
The colours are afterwards. transferred by means of a suitable press, operated
by hand or mechanically, onto a sheet or plate of india-rubber or other suitable
material such as glass or celluloid, the said plate being engraved with the drawings
or characters to be printed or it may be plain or stippled, chequered or otherwise
marked if the colours are only to be transferred onto a sheet already printed with a
siugle shade or tint.
A hand-press suitable for carrying out any process consists of a frame provided
with a carriage. or bed sliding in. lateral guides, the inking plate or colour-
receptacles being placed towards one end of such carriage or bed and the sheet to
be printed towards the other eud.
A platen guided by ribs on standards secured to the frame is carried by, a
vertical bar which is kept in a raised position by means of a spiral spring enclosed
within a casing ou a cross-bar. For the purpose of allowing of inspection and
the replacing of the transferring plate the cross-bar is jointed to one of the
standards and its other end rests in a fork in the other standard and is secured.
therein by a bolt or pin.
The operating lever is. jointed to a small connecting rod movable upon a joint
on the cross-bar and an adjustable stop is arranged on the said cross-bar for
limiting, the downward stroke of the lever.
The carriage or bed also carries two adjustable. stops, which limit its movement
in either direction in order to allow of registering the inking plate and sheet
to be printed with the, platen of the press, the said stops abutting, against
the frame.
The inking plate, prepared as already explained, is brought beneath the platen
by sliding the bed, along until the. stop, abuts against the frame and the platen
18:then lowered. The transferring plate fixed beneath the platen bears upon
the inking plate and takes the colours carried by the latter; the platen is, then.

page_text: allowed to rise and the bed is slid in the opposite direction so as to bring the
sheet into position for receiving the impression. By again pressing upon the hand-
lever the platen will deposit upon the sheet the colours which it has received
from the inking plate. !

Improvements relating to Colour-printing, and to Apparatus
therefor.
I, JEAN BACHELERIE, of 50, Rue des Boulets, Paris, in the Republic of France,
Manufacturer, 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 :-
My invention relates to a new system of printing in several colours, the said
printing being effected at one impression or operation by means of a sheet of felt
acting similarly to that of a wet stamp.
This process is applicable for the multiple colour-printing of engravings,
drawings, typographic impressions, either printed directly with all their colours
or previously printed with a single tint, black or the like.
The process is also applicable for producing upon the already coloured sheet a
superposition of tints giving it the final or finishing shades.
For this purpose, the arrangement of the colours which are to be applied upon
the sheet being known, I cut out of a sheet of felt, cloth or other material capable
of receiving and holding the colour, such as powdered cork, the outlines of each
part which is to be of the same colour throughout and after having saturated the
various pieces of felt with the proper colours I unite them to form an inking plate
which presents all the colours at the places where they are required. The various
colour-receptacles thus formed can if required be separated by strips to prevent
the colours from running into one another."
The colours are afterwards transferred by means of a suitable press, operated
by hand or mechanically, onto a sheet or plate of india-rubber or other suitable
material such as glass or colluloid, the said plate being engraved with the drawings
or characters to be printed or it may be plain or stippled, checkered or otherwise
marked if the colours are only to be transferred onto a sheet already printed with
a single shade or tint.
In the accompanying drawing,
Figure 1 is a longitudinal section of a hand-press suitable for carrying out my
process:

Figure 2 is a transverse section of the same; and,
Figure 3 is a plan with the platen and its support removed.
A is the frame of the press provided with a carriage or bed' B sliding in lateral
guides C, the inking plate or colour-receptacles D being placed towards one end
of such carriage or bed and the sheet E to be printed towards the other end, as
clearly shown in Figure 3.
The platen F guided by ribs on standards K and L secured to the frame A is
carried by a vertical bar G which is kept in a raised position by means of a spiral
spring H enclosed within a casing on a cross-bar I. For the purpose of allowing
of inspection and the replacing of the transferring plate J the cross-bar is jointed
to one of the standards K and its other end rests in a fork in the other standard L
and is secured therein by a bolt or pin.

page_text: The operating lever M is jointed at a to a small connecting rod N movable
upon a joint 6 on the cross-bar I and an adjustable stop c is placed on the said
cross-bar for limiting the downward stroke of the lover.
The carriage or bed B also carries two adjustable stops d,,d" which limit its.
movement in either direction in order to allow of registering the inking plate D
and the sheet E to be printed with relation to the platen of the press, the said
stops abutting at e, el respectively against the frame A.
The inking plate D prepared as already explained, is brought beneath the
platen F by sliding the bed B along until the stop d abuts against the frame at e
and the platen is then lowered. The transferring plate J fixed beneath the platen
bears upon the inking plate D and takes the colours carried by the latter; the
platen is then allowed to rise and the bed is slid in the opposite direction so as to
bring the sheet E into position for receiving the impression. By again pressing
upon the hand-lever the plate J will deposit upon the sheet the colours which it
has received from the inking plate D.
Figure 4 represents an example of a print executed by my process.
The system of printing can be used for the decoration or printing of surfaces of
any dimensions and form whether flat or not, as well as for printing on sheets of
any suitable material.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
1. The system of printing in several colours at one operation comprising as
essential distinctive characteristics.―
(a) The arrangement of the inking plate formed by the juxtaposition of
pieces of felt, linoleum or other suitable colour holding material, cut out to
the outline of the print to be obtained, each of the said pieces of felt being
saturated with the proper colour according to its position, substantially as
herein before described.
(b) The arrangement of the transferring plate fixed to the platen of the
press, the said plate being engraved or carrying typographic characters, or
simply consisting of a plain, stippled or checkered sheet and receiving the
colours from the inking plate in order to transfer them onto the sheet to be
printed or coloured, substantially as set forth.
2. The improved apparatus or press for printing in several colours at one
operation herein before described and illustrated in the accompanying drawing.
