IMPROVEMENTS IN APPARATUS TO BE ATTACHED TO LITHO- GRAPHIC AND LETTER PRESS PRINTING MACHINES, FOR GUMMING, VARNISHING SIZING, AND COLORING SHEETS, OR CONTINUOUS ROLLS OF PAPER OR OTHER SUITABLE SUBSTANCE
Year: 1884

I WILLIAM GREAVES of Vincent Machine Works, New Wortley, Leeds in the
county of York Lithographic Printing Machine Maker do hereby declare the nature
of my Invention for "IMPROVEMENTS IN APPARATUS TO BE ATTACHED TO LITHO-
GRAPHIC AND LETTER PRESS PRINTING MACHINES, FOR GUMMING, VARNISHING
SIZING, AND COLORING SHEETS, OR CONTINUOUS ROLLS OF PAPER OR OTHER
SUITABLE SUBSTANCE" to be as follows :-
The object of my invention is to construct an apparatus, which when applied to
a lithographic or letter press printing machine, will effectively varnish, size, gum,
or color sheets or continuous rolls of paper, or other suitable substance and regulate
the amount of varnish, size, gum or color applied thereto, and thereby effect a
considerable saving in the cost, as heretofore a seperate machine has to be made for
this purpose, and by removing my apparatus and replacing brackets for damping
and roplacing brackets for damping, or other roller brackets, the machine can be
used for lithographic or printing purposes; I attach to the cylinder (or its wheels)
of a lithographic or printing machine, a pinion wheel gearing into a second pinion
wheel on a shaft carrying a feed roller, which gears into a third pinion wheel on the
shaft of a regulating roller, this wheel gears into a pinion wheel on the shaft of the
supply roller, the supply roller revolving in a trough containing the required liquid
a pivotted regulating plate bears upon the periphery of the regulating roller and so
regulates (by means of screws or springs,) the application of the varnish size gum or
color or other liquids the action is as follows, the supply roller passes the liquid
substance to the regulator roller, the regulating plate and screws adjusting the
quantity of the feed, passes it to the feed roller, from which the sheet receives its
coating or covering, by being fed into the printing machine in the ordinary way.

Sizing, and Colouring Sheets or Continuous Rolls of Paper or
other suitable Substance.
I WILLIAM GREAVES, of Vincent Machine Works, New Wortley, near Leeds,
in the county of York, Lithographic Printing Machine Maker, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN APPARATUS TO
BE ATTACHED TO LITHOGRAPHIC AND LETTER PRESS PRINTING MACHINES, FOR
GUMMING, VARNISHING, SIZING AND COLOURING SHEETS, OR CONTINUOUS ROLLS OF
PAPER OR OTHER SUITABLE SUBSTANCE" and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
The object of my invention is to construct an apparatus which when applied to
lithographic or letter press printing machines,, will effectually varnish, size and 1
gum, or color sheets, or continuous rolls of paper, metal, or other suitable substance,
and regulate the amount of varnish, size, or gum applied thereto, and thereby effect
a considerable saving in the cost; as heretofore a separate machine has to be made
for this purpose and by removing my apparatus, and replacing brackets, for
damping, or other roller brackets, the machine can be used for lithographic or 1
printing purposes.
I attach to the cylinder brake wheel, or the wheel, shaft or cylinder of a
lithographic or printing machine, a spur wheel gearing into a pinion wheel on a
shaft carrying a feed roller, which gears by means of a pinion wheel into a third
pinion wheel on the shaft of a regulating roller, this wheel gears into a pinion
wheel on the shaft of the supply roller, the supply roller revolving in a trough
containing the required liquid; the trough is supplied with the necessary liquid
by flexible pipe connecting the trough and the cistern, mounted on table and
guide rods and adjustable as to its height by spring or india-rubber band, and cord
or chain passing over guide pulleys, and carrying weight; a pivotted regulating
plate bears upon the periphery of the regulating roller and so regulates, by means
of screws or springs the application of the varnish, size, gum, color, or other
liquids, as well as excludes the air from the roller, the action is as follows:-
The supply roller passes the liquid substance to the regulating roller, the
regulating plate and screw adjusting the quantity of the feed, passes it to the
feed roller from which the sheet receives its coating or covering by being fed into
the machine in the ordinary way.

page_text: I attach to the cylinder brake wheel, or the wheel, shaft or cylinder A of a
lithographic or printing machine B, a spur wheel O gearing into a pinion wheel D
on a shaft E carrying a feed roller F, which gears by means of a pinion wheel D¹
into a third pinion wheel G on the shaft H of a regulating roller J, this wheel
gears into a pinion wheel K on the shaft M of the supply roller N, the supply-
roller revolving in a trough P, containing the required liquid; the trough is
supplied with the necessary liquid by flexible pipe O connecting the trough P, and
the cistern S, mounted on table T and guide rods T¹, and adjustable as to its
height by spring or india-rubber band W, and cord or chain U passing over guide
pulleys V and V and carrying weight U₁, a pivotted regulating plate L bears upon
the periphery of the regulating roller J, and so regulates by means of screws Ⓡ or
springs, the application of the varnish, size, gum, color, or other liquids, as well as
excludes the air from the roller, the action is as follows:-
The supply roller N passes the liquid substance to the regulating roller J, the
regulating plate L and screw R, adjusting the quantity of the feed, passes it to the
feed roller F from which the sheet receives its coating or covering by being fed
into the machine in the ordinary way.
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 application of an apparatus for regulating and adjusting the feed to
lithographic and letter press printing machines (for gumming varnishing, sizing
and coloring sheets, or rolls of paper, metal, or other material) placed in any
position on the machine.
(2.) The use and employment of a pivotted plate bearing upon the periphery of
the regulating roller or such equivalent, as and for the purposes shewn and
described.
(3.) The apparatus for adjusting the cistern as shewn and described.
