My Invention consists in an improved process of and apparatus for effecting the
transfer of designs, drawings, pictures or other representations from plates or
lithographic stones or the like to metal rollers as a preliminary to the engraving of
the said rollers for printing purposes.
According to my said Invention I effect the transfer by means of an india
rubber surface which may be effected as follows:-I tako the engraved plate or
litho stone upon which the design or representation has been produced and I place
it upon a table which is or can bo traversed under an india rubber roller which can
be raised and lowered as required. I bring down the said india rubber roller upon
the inked plate or stone and by revolving the said india rubber roller under
pressure against the inked plate or stone the design or representation becomes
transferred to the india rubber roller. I then raise the india rubber roller from
the plate or stone and withdraw the table and I bring the india rubber roller and
the metal roller into contact and rotate them under pressure so that the design or
representation is transferred to the metal roller which is afterwards etched or
engraved by the usual or any suitable processes.
In place of the india rubber surface being arranged as a roller I may arrange it
as a flat surface upon the table and transfer the design to it from the plate by the
pressure of a roller above; When this is done the said india rubber surface ių

page_text: traversed in contact with the metal roller to be engraved and the design becomes
transferred thereto.
I do not limit myself to the use of india rubber as the material upon which to
take the transfer as printers roller composition and such like compositions will
answer the purpose but will not wear so long as india rubber.

J, GABRIEL RAPHAEL HUGON of 8 Union Court Old Broad Street, in the City of
London, Merchant, do hereby declaro the nature of said invention for "IMPROVE-
MENTS IN AND APPARATUS FOR EFFECTING THE TRANSFER OF DESIGNS OR
REPRESENTATIONS FROM PLATES OR LITHOGRAPHIC STONES OR THE LIKE TO
METAL ROLLERS AS A PRELIMINARY TO THE ENGRAVING OF THE SAID ROLLERS
FOR PRINTING ON CALICO AND OTHER FABRICS AND MATERIALS and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :—
My Invention consists in an improved process of and apparatus for effecting the
transfer of designs drawings pictures or other representations from plates or
lithographic stones or the like to metal rollers as a preliminary to the engraving
of the said rollers for printing purposes.
According to my said Invention I effect the transfer by means of an india rubber
surface which may be effected as follows I take the plate or litho stone upon
which the design or representation has been produced and I place it upon a table
which is or can be traversed under an india rubber roller which can be raised and
lowered as required I bring down the said india rubber roller upon the inked
plate or stone and by revolving the said india rubber roller under pressure against
the said inked plate or stone the design or representation becomes transferred to the
india rubber roller I then raise the india rubber roller from the plate or stone and

page_text: withdraw the table and I bring the india rubber roller and the metal roller into
contact and rotate them under pressure so that the design or representation is
transferred to the metal roller which is afterwards etched or engraved by the usual
or any suitable processes.
In place of the india rubber surface being arranged as a roller I may arrange it
as a flat surface upon the table and transfer the design to it from the plate by the
pressure of a roller above-When this is done the said india rubber surface is
traversed in contact with the metal roller to be engraved and the design becomes
transferred thereto.
I do not limit myself to the use of india rubber as the material upon which to
take the transfer as printers roller composition and such like compositions will
answer the purpose but will not wear so long as india rubber.
And in order that my said Invention may be fully understood I shall now
proceed more particularly to describe the same and for that purpose shall refer to
the several figures on the annexed sheet of drawings the same letters of reference
indicating corresponding parts in all the figures.
Figures 1. 2 and 3 of the accompanying drawings represent respectively a front
elevation an end view and a plan of a machine for transferring designs on to metal
rollers according to my Invention and Figures 4 and 5 are details which will be
hereinafter referred to.
The design to be engraved on the copper or other metal roller is first produced
by engraving drawing or otherwise on lithographic stone zincographic or other
plate or the like and the stone plate or the like with a design thereon is placed on
the table or platform A which is provided with wheels a arranged to travel on ribs
or guides 6 on the sides or ond standards B of the machine-C is the transferring
roller composed of or coated with india rubber, printing roller composition or other
suitable yielding material on to the surface of which the design is printed or
transferred from the stone or the like as hereinafter described-This roller is
mounted in bearings o in sliding blocks D fitted to slide vertically in guides E fixed
on opposite ends of the machine the said guides with the roller being adjusted in
height to suit different sizes of rollers to be engraved by the angular goaring
actuated by the means of the handle e' so as to cause the screwed rods & depending
from the blocks D to rotate in nuts carried in weighted lovers D' centered at d³ to
the standards B of the machine. The metal roller to be engraved and to which the
design on the stone or the like is to be transferred is mounted on a mandril F see
Figures 4 and 5 carried in headstocks G fitted on one end of the table or platform A.
which table is provided with a toothed wheel H in gear with rack teeth on the
framing of the machine by means of which the table is traversed beneath the
roller C and in order to ensure the speed and amount of travel of the table A being
uniform with the surface speed and peripheral motion of the roller C discs I are
mounted loosely on the axis of the roller round which discs steel straps i are passed
their ends being connected to bars K fitted to slide transversely in the blocks D the
said bars being also capable of sliding vertically in guides L fitted to slide trans-
versely on the table A to admit of the bars being raised and lowered with the
roller C. The discs I are connected to the roller C so as to cause them to rotate
therewith by pins or pegs M passing through the discs and entering holes in the
end of the roller.
The stone, plate, or the like with the design thereon is placed on the table A and
inked in the ordinary manner and the table A is then traversed by means of the
handle a and wheel H along the framing of the machine until the end of the stone,
or the like, is brought beneath the roller C. This roller is then lowered on to the
surface of the stone by rotating the angular wheels c causing the screwed rods & to
turn in the nuts in the weighted levers D' which levers are supported so as not to
exert pressure on the stone by projections D' on opposite ends of a transverse
spindle D The table having been brought into this position the spindle D³ia
turned in its bearings by the lover handle D' so as to release the weighted lovers D'
which will thou cause the rollers C to bear with the requisite degree of pressure

page_text: upon the stone or the like on the table A. The table A is then traversed beneath
and in contact with the roller C by means of the handle a¹ and the wheels H;
whereby a copy or impression of the design on the stone is transferred or printed
on the roller C the steel straps i causing the said roller and the table to travel at
the same relative surface speed.
The design having been thus transferred to the roller C the said roller is raised
by means of the gearing e so as to admit of the metal roller P carried in the
headstocks G in the table A being brought by a further motion of the said table
beneath the roller C which roller is then lowered and caused to bear with pressure
upon the roller P.
The pins or pegs M which connect the discs I to the roller C are then removed
and the said roller is rotated by means of the worm and worm wheel Q against the
surface of the metal roller P which is thus caused to rotate in the head-stocks G
and thereby receive thereon from the roller C a copy or transfer of the design. The
roller C is then raised out of contact with the roller P and the table with the
roller P is withdrawn from beneath the roller C.
The roller P with the design thereon may then be removed from the headstocks G
to be engraved etched or otherwise treated. R is a roller fitted to turn in the
framing of the machine beneath the table A and in vertical line with the roller C
its object being to support the table at the part where the pressure is applied.
Although I have described the stone or plate as being caused to travel beneath
the transferring cylinder it is obvious that the stone or plate may remain stationary
and the transferring cylinder be caused to travel over it.
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
First. The system or mode of transferring designs, drawings, pictures or other
representations from plates or lithographic stones or the like to metal rollers
substantially as herein before described.
Second. In apparatus for transferring designs drawings pictures or other repre-
sentations from plates or lithographic stones or the like to metal cylinders the
combination of a table or platform A and a transferring roller C constructed and
arranged to operate substantially in the manner hereinbefore described.
Third. The general construction combination and arrangement of parts consti-
tuting an apparatus for transferring designs from plates lithographic stones and the
like to metal rollers preliminary to the engraving of the said rollers substantially
as herein before described and illustrated by my drawings.
