WILLIAM CHANCELLOR HAIGH of the City of Manchester Artist
MENTS IN APPARATUS FOR PRINTING,"
" IMPROVE-
The object of the improvements is to enable printing to be accomplished in one
or more colours in a simple and expeditious manner, and consists in printing from
specially prepared rollers or blocks or tablets upon which the letters, figure or
device are formed either in relief, or drawn or marked upon a flat surface in manner
similar to lithography, To effect this and to carry out my improvements, I prepare
a roller or rollers, or a block or tablet composed of iron, wood, or any other suitable
material which roller or rollers, block or tablet, I cover with a suitable gelatinous
composition, or it may be of india rubber.
This covering is engraved, etched, stamped or cast so as to bring the device into
relief, and is then capable of being inked or coloured by any suitable method, and
brought in contact under the required pressure with the paper or other material to
be printed. Where it is required to print as in lithography I prepare a suitable
roller or block or tablet of metal or wood or a combination thereof, and I cover the
surface with cement or a mixture of cement and other substances in such manner
that the device to be printed may be transferred thereon which is then capable of
being inked or coloured for printing purposes as in the former case.

WILLIAM CHANCELLOR HAIGH, of the City of Manchester, Artist. " IMPROVE-
MENTS IN APPARATUS FOR PRINTING."
The object of the Improvements is to enable the printing of bill posters and other
large surfaces, to be accomplished in one or more colours, in a simple and expeditious
manner, and consists in printing from specially prepared rollers, or blocks, or tablets,
upon which the letters, figure, or device are formed either in relief, or drawn or
marked upon a flat surface in manner similar to lithography.
To effect this, and to carry out my improvements, I prepare a roller or rollers, or
a block or tablet, composed of iron, wood, or any other suitable material, which
roller or rollers, block or tablet, I cover with a suitable gelatinous composition, or
it may be of india-rubber.
This covering is engraved, etched, stamped or cast, so as to bring the device into
relief, and is then capable of being inked or coloured by any suitable method, and
brought in contact, under the required pressure with the paper, or other material to
be printed, either by hand or power.
When it is required to print as in lithography, I prepare a suitable roller or
block, or tablet, of metal or wood, or a combination thereof, and I cover the surface
with cement, or a mixture of cement and other substances, in such manner, that the
device to be printed may be transferred thereon, which is then capable of being
inked or coloured for printing purposes as in the former case.
Having now described my improvements, and means adopt in carrying the
same into effect, I would have it understood that I do not confine myself to the
precise details described, as variations may be made, without departing from the
peculiar character of the invention
But what I do claim is
1. The covering of the surfaces of rollers or blocks, or tablets, of iron, wood,
or other suitable material, with a gelatinous composition, or india-rubber, for the
special purpose herein described, which composition or india-rubber is engraved,
etched, stamped or cast, so as to bring into relief a device required to be printed, in
manner substantially as described.
2. The covering of the surfaces of rollers, or blocks, or tablets, of wood or iron
or a combination thereof, for the special purpose herein described, with cement, or
a mixture of cement and other substances, in such manner that a device to be
printed as in lithography may be transferred thereon in manner substantially as
described.
In witness whereof, I, the said William Chancellor Haigh, have hereunto set my
hand and seal, this Nineteenth day of February, in the year of our Lord, One
thousand Eight Hundred and Eighty-three
