Improvements in Printing what are known as Sanitary" or
"Washable" Paper-hangings.
We JOHN WALKER and HARRY CARVER both of Whit Lane Works, Orchard
Street, Pendleton in the county of Lancaster, Manufacturers of Paper-hangings do
hereby declare the nature of this invention to be as follows:-
Hitherto those paper-hangings known as "sanitary" or "washable" paper-hangings
have been printed by means of or with the aid of a roller or rollers in which or each
of which the pattern to be printed is formed by being engraved or etched or other-
wise incised therein, a "doctor" or "doctors formed of metal being used in
conjunction with the roller or each of the rollers before referred to.

According to our invention we employ a roller or rollers or a lock or blocks the
pattern upon which roller or block or upon each of which rollers or blocks we form
by removing or adding portions so as to leave the portion or portions forming the
pattern, raised or in relief. To the pattern raised or in relief upon such roller or
blork or rollers or blocks we supply oil-colour or varnish-colour" by means of a
roller or rollers formed of gelatine, india-rubber or other suitable material or we
supply oil-colour " or varnish-colour to the raised or relief portions of the said
roller or block or rollers or blocks by means of a sieve or apron or sieves or aprons
formed of leather, india-rubber or other suitable material and similar to those
ordinarily employed for supplying colour" to the printing rollers used in mana-
facturing ordinary or surface" paper-hangings printed with water-colours."

By means of our invention we are enabled to print a pattern upon a paper hanging
in one or more or several colours or shades in oil-colours or" varnish-colours" by
means of rollers or blocks the pattern upon which rollers or blocks is formed in relief
and we are thereby enabled to produce from the surface of such rollers or blocks a
paper-hanging which is "sanitary" and washable.

Improvements in Printing what are known as 'Sanitary" or
"Washable Paper-hangings.
We JOHN WALKER and HARRY CARVER both of Whit Lane Works, Orchard
Sireet, Pendleton in the county of Lancaster Manufacturers of Paper-hangings 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:
Hitherto those paper-hangings known as sanitary
washable paper-
hangings have been printed by means of or with the aid of a roller or rollers in which
or each of which the pattern to be printed is formed by being engraved or etched or
otherwise incised therein, a "doctor" or "doctors" formed of metal being used in
conjunction with the roller or each of the rollers before referred to.

By means of our invention we are enabled to print a pattern upon a paper-
hanging in one or more or several colours** or shades" in "oil-colours
"varnish colours by means of printing rollers the pattern upon which printing
rollers is formed in relief and we are thereby enabled to produce from the surface of
such printing rollers a paper-hanging which is "sanitary and washable.

One method of carrying our invention into effect is illustrated in Fig. 1 of the
accompanying drawing which shows in section so much of a "single colour printing
machine
for printing what are known as "sanitary" or washable paper-hangings
as is necessary to illustrate the method of carrying our invention into effect.
the printing roller on which the pattern to be printed is formed. is a roller the
surface or circumference of which can by means of screws or other suitable appliances
be pressed against the surface or circumference of the roller a. c is a roller the
surface or circumference of which can by means of sereys or other suitable appliances
be pressed against the surface or circumference of the printing roller a. The
surfaces or circumferences of the rollers b, c we frm of indiarubber or other
suitable elastic material. dis a trough or box fo containing "oil-colour" or
"varnish colour." Dipping into the
oil colour or varnish colour" contained in
the trough or box d is a roller e the surface or circumf. rence of which may by meaus
of screws or other suitable appliances be pressed against the surface or circumference
of the roller c. The surface or circumference of the roller e may be formed of
gelatine, indiarubber or other suitable elastic mater ordinarily employed to form
the rollers employed for supplying "colour" to the printing rollers used in manu-
facturing ordinary or surface" paper-hangings, printed with

paper to be operated upon is indicated by the strong line A.
or
water-colours." The
We form the pattern upon the roller a as shown in the diagram Fig. 2, the
surfaces B of the raised portions B being the portion which receives the "oil-colour"
varnish-colour" from the roller c and transfers it to the paper to be printed upon.
The rollers a, b, c are so geared together by means of wheels that the surface
speed of the roller b, and the surface speed of the roller c shall each be equal to the
surface speed of the roller a. We so gear the roller e to the roller c that the surface
speed of the roller e shall be a little greater than the surface speed of the roller c
thereby ensuring that the roller e shall receive a plentiful supply of "colour."

Although we have for convenience only shown in Fig. La machine arranged to
print one colour it will be readily understood by persons conversant with
machinery or apparatus for printing paper-hangings that our invention is applicable
to printing a pattern upon paper-hangings in one or more or several "colours," or
shades 12 " oil-colours" or varnish-colours."

Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is :

"
The hereinbefore described method of printing what are known as "sanitary" or
washable" paper-hangings in "oil-colours or * varnish-colours which consists
in applying oil-colour or varnish-colour to the surface only of the printing
roller or printing rollers employed to print the pattern upon the paperhangings and
not to the lines, cavities, depressed portions or devices formed in such printing
rolier or printing rollers.
