My invention is an improvement of, and, an addition, to the invention described
in the specification of the Letters Patent granted to me, and dated October 8th 1880,
No 4097.
One part of my invention is the use of steel knives, or blades formed, or
arranged in ornamental shapes, or designs, and operated with in the manner
described by the specification of the aforesaid Letters Patent, such knives, or
blades, being intended to be used chiefly in the decoration of wood cut, on what is
known in the timber trade as "the plank," to form an ornamental work for various
purposes.
These knives, or blades are used for cutting into, or severing the fibre of the
wood, and for restraining, and keeping within the outline, defined by said knives,
or blades the liquid stains, dyes, or colors employed in the operation. This
invention differs from that secured by my aforesaid Letters Patent in the following
important features namely I use a separate and distinct blade for each stain, dye,
or color, instead of a number of knives, or blades attached to a plate, and used
collectively, and the incision made by each knife, or blade has the dual effect of
limiting the extent to which the stain, dye, or color shall flow, and also of imparting
to the plank the character, and effect of inlaid wood-work. I apply the liquid

page_text: stains, dyes, or colors preferably with a brush, but I may simply pour them on the
surface of the wood between the knives, or blades. Instead of using knives or
blades I may first point by lithographic or other convenient means either by
what is termed the "set off" method of printing with transfer paper, indiarubber,
cloth, or other suitable material, or direct from zinc, or lithographic stone the
necessary lines or designs limiting the stains, dyes, or colors, within the desired
bounds for the exact delineation of the ornament, and thereby preventing said
stains, dyes, or colors from flowing beyond said limitations. Or I may in the first
instance apply the stains, dyes, or colors to the wood, or other material with a
stencil, or brush, and afterwards print the lines, or outlines of the design by
lithographic, or other convenient process, so as to exactly define the design or
pattern. For printing direct on to the wood, or other material I may use either a
zinc plate or lithographic stone, on which the design is drawn, or delineated by the
ordinary lithographic methods, or I may use rollers made of zinc, or lithographic
stone prepared in the same manner, and with which I then print the design on the
wood, or other material.
Another part of my invention relates to the printing simultaneously by one
operation two or more pieces, or slabs of wood, or other material by placing them
back to back whilst they are being rolled, or pressed in the methods hereinbefore
described.

" IMPROVED
METHODS OF AND APPARATUS FOR PRODUCING COLORED. PATTERNS OR DESIGNS
UPON OR IN OR OTHERWISE DECORATING WOOD, MARBLE, LEATHER, AND SIMILAR
MATERIALS
HENRY CHALK WEBB of the City of Worcester Manufacturer
"
My Invention is, an improvement of, and an addition to the invention described
in the Specification of the Letters Patent granted to me and dated October 8th 1880,
No 4097. One part of my invention is the use of steel knives, or blades formed,
or arranged, in ornamental shapes or designs and operated with in the manner
described by the specification of the aforesaid Letters Patent and delineated by
Figure 4 of the drawings accompanying said specification, such knives or blades being
intended to be used chiefly in the decoration of wood, cut upon what is known in
the timber trade as "the plank" to form ornamental work for various purposes..
These knives or blades are used for cutting into, or severing the fibre of the wood,.
and for restraining and keeping within the outline defined by said knives or blades
the liquid stains, dyes, or colors employed in the operation. This invention differs
from that secured by my aforesaid Letters Patent in the following important
features namely. I use a separate and distinct blade for each stain, dye, or color
as shown in said Figure 4 herein before referred to, instead of a number of knives or
blades attached to a plate, and used collectively, and the incision made by each.
knife or blade has the dual effect of limiting the extent to which the stain, dye, or
color shall flow, and also of imparting to the plank the character, and effect of
inlaid wood work. I then apply the liquid stains, dyes, or colors preferably with
a brush, but I may simply pour them on the surface of the wood between the
knives or blades. Instead of using knives or blades, I may first print by lithographic
or other convenient means either by what is termed the "set off" method of
printing with transfer paper, indiarubber, cloth, or other suitable material, or direct
from zinc, or lithographic stone, the necessary lines, or designs limiting the stains,
dyes, or colors, within the desired bounds for the exact delineation of the
ornament, and thereby preventing said stains dyes or colors from flowing beyond
said limitations. Or I may in the first instance apply the stains dyes or colors to
the wood or other material with a stencil, or brush, and afterwards print the lines,
or outlines of the design by lithographic, or other convenient process so as to
exactly define the design or pattern. For printing direct on to the wood, or other
material I may use either a zinc plate or lithographic stone on which the design is
drawn or delineated by the ordinary lithographic methods or I may use rollers
made of zinc, or lithographic stone prepared in the same manner and with which I
Another part of my
then print the design on the wood or other material.
invention relates to the printing simultaneously by one operation two or more
pieces or slabs of wood or other material by placing them back to back whilst they
are being rolled or pressed in the methods hereinbefore described. For carrying
into practice that portion of my invention, which relates to the printing by "set
off" or direct on to the wood I employ a specially designed machine delineated
by figures 1. 2. 3 of the accompanying drawings in which A represents a travelling
bed plate of suitable material, actuated by the screw D. B figures 2, and 3 represents
a roller by means of which the wood or other material placed on the aforesaid bed-
plate A receives the necessary amount of pressure for the printing by "set off" or
) direct.
C represents the bed or base upon which the bed-plate A travels.

page_text: E figure 1 represents a lever and sliding weight for regulating the amount of
pressure to be given by the roller B.
The manner in which the printing by "set off" is effected is preferably to coat
the travelling bed with indiarubber on which the transfer is placed. The slab of
wood is then placed upon the transfer and the roller B is regulated by moveable
bearings as delineated in the accompanying drawing, in a manner to give the
required pressure. The bed-plate A being then actuated by the screw D is
caused to travel the required distance thereby completing the printing on the
wood or other material. The same process is exactly observed when lithographic
stone, or zinc is used instead of transfer paper or other material, but the transfer
paper receives the impression of the pattern or design first from lithographic stone
or zinc, and then transfers it to the wood or other material, whereas the lithographic
stone, or zinc gives the impression direct.
Having now fully explained the nature of the said invention and the means by
which it can be carried into practice, I claim 1st The use of steel knives for making
incisions into plankwise wood, and severing the fibres thereof, for the dual purpose
of limiting the extent to which the stain, dye, or color shall flow and also of
imparting, to the plank the character and effect of inlaid wood work. 2nd The
combined use of lithographic or other methods, of printing by transfer, "set off" or
direct on to the wood; or other material, and the use of liquid spirit or other stains,
dyes, or colors for the objects and purposes herein before described. 3rd The use of
the special machine delineated by figure 1 of the accompanying drawings for
printing on to the wood or other articles either by transfer, "set off," or direct as
particularly described in the foregoing specification. 4th The printing by transfer,
set off, or direct of two or more slabs by simultaneous pressure by placing them
back to back and passing them between a pair of rollers, or roller and travelling
table substantially as herein before described. In Witness whereof I the said
Henry Chalk Webb have hereunto set my hand and seal this twenty fifth day of
January in the year of our Lord One thousand Eight Hundred, and Eightyfour.
