PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Preparing the Edges of Wall Papers
and the like ready for Trimming.
I, DOCTOR WALSH YATES, of Holland House, Radcliffe, in the County of
Lancaster, Paper-hanging Manufacturer, do hereby declare the nature of this
invention to be as follows;-
The object of this invention is to provide an appliance to be fitted to machines
for printing wall papers and similar coverings for ceilings or walls, in order
that the hangings may be supplied slotted or perforated ready for trimming with-
out the use of shears or other like instruments by the paper-hanger.
The invention comprises special slotting or perforating devices and means
for adjusting the same, special bearings or brackets for their support and special
means for supporting the paper whilst it is being perforated or slotted.
The cutters themselves may consist of a thin disc with serrated or saw like
edges mounted on a shaft so that its cutting edge works in a grooved disc upon
a second shaft parallel with the first. Or the serrated cutter may work between
two dished discs fixed face to face at a suitable distance apart and held in place
by springs on the second shaft.
When I wish to make a series of long slits in the paper I form the edge of
the cutting disc plain but with a number of notches.
I may use a pair of flanged discs, one on each shaft the edges of the flanges
facing each other and being provided with a series of notches or slots, or I may
use a dished disc with notched edges on one shaft and a flanged disc with corre
sponding notched edges on the second shaft. In either of the cases last named
one of the discs is held to its place by a spring.
I propose also to mount a disc on one cutter engaging with a grooved pulley
or block on the other cutter and to provide a feather or similar adjusting device
for one cutter so that it can slide on its shaft and be adjusted by the adjustment
of the other cutter..
The lower perforating device at one end of the second shaft is capable of sliding
on its shaft upon a feather or the like the feather or like device on the first
shaft being at the other end thereof.
The shafts are mounted in brackets or bearings fitted to the sides of the print-
ing machine.
One bracket is fixed to the frame and provided with a dead-eye through which
one of the shafts (say the lower shaft) passes, and also with an upright slide
and bearings for an adjusting screw passing through a sliding block fitted in
the slide. This sliding block has a transverse slide and bearings for a second
adjusting screw which acts on a bearing by which the upper shaft can be adjusted
sideways.
By these means the whole device can be adjusted sideways or the upper shaft"
adjusted with regard to the lower shaft or either perforating or slotting device
can be adjusted upon the shafts.

page_text: The paper as it passes between the perforating or slotting devices is supported
and kept flat by a roller or drum upon one of the shafts between the two per-
forating devices and a second separate roller or bar is preferably mounted close
to the said devices for this purpose, so that the whole width as well as the central
part of the paper is supported and kept flat.

Improvements in Apparatus for Preparing the Edges of Wall Papers
and the like ready for Trimming.
I, DOCTOR WALSH YATES, of Holland House, Radcliffe, in the County of
Lancaster, Paper-hanging Manufacturer, 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:-
The object of this invention is to provide an appliance to be fitted to machines
for printing wall papers and similar coverings for ceilings or walls, in order
that the hangings may be supplied slotted or perforated ready for trimming with-
out the use of shears or other like instruments by the paper-hanger.
The manner in which my said invention is to be performed or carried into
practical effect will be readily understood on reference to the annexed sheet of
drawings and the following explanation thereof.
Fig. 1 on the drawings is an end view and Fig. 2 an elevation of so much
of a machine for printing wall papers as is necessary to illustrate the application
of my improved apparatus thereto, A being part of the end framing of the
machine and B the bed-roller against which the printing takes place.
Fig. 2 is an end view of my improved apparatus, and Figs. 3, 4, 4 and 5 are
detached views on a larger scale of modifications of the cutting or slotting
arrangements hereinafter more particularly referred to.
The invention comprises special slotting or perforating devices and means for
adjusting the same, special bearings or brackets for their support and special
means for supporting the paper whilst it is being perforated or slotted.
The cutters themselves may consist as shown at Figs. 12 and 2ª, of a thin
disc a with serrated or saw like edges mounted on a shaft so that its cutting
edge works in a grooved disc c upon a second shaft d parallel with the first. Or
the serrated cutter a may work as shown at Fig. 3 between two dished discs e
fixed face to face at a suitable distance apart and held in place by springs f on
the second shaft d.
When I wish to make a series of long slits in the paper I form the edge of
the cutting disc plain but with a number of notches, at intervals so that it cuts
a number of slits with interstices between. Or I may use a pair of flanged
discs gas shewn in elevation at Fig. 4 and end view Fig. 44, one on each shaft
the edges of the flange facing each other and being provided with a series of
notches or slots or I may use a dished disc h with notched edges on one shaft b
as shown at Fig. 5, and a flanged disc g with corresponding notched edges on
the second shaft d. In either of the cases last named one of the discs is held
to its place by a spring f.
I propose also to mount a disc k on one cutter engaging with a grooved pulley
or block on the other cutter (see Figs. 2, 3 and 5) and to provide a feather or

page_text: similar adjusting device for one cutter so that it can slide on its shaft and be
adjusted by the adjustment of the other cutter.
The lower perforating device c at one end of the second shaft d is capable of
sliding on its shaft upon a feather or the like the feather or like device on the
first shaft being at the other end thereof.
The shafts are mounted in brackets or bearings m fitted to the frame A of
the printing machine.
These brackets are fixed to the frame (see Figs. 2 and 24) and provided with
a dead eye through which one of the shafts (say the lower shaft) passes, and
they are each provided with an upright slide and bearings for an adjusting
passing through a sliding block fitted in the slide. This sliding block has
a transverse slide 7 and bearings for a second adjusting screw q which acts on
a bearing by which the upper shaft can be adjusted sideways.
screw o
By these means the whole device can be adjusted sideways on the upper
shaft and this shaft can be adjusted vertically with regard to the lower shaft d
or either perforating or slotting device can be adjusted upon the shafts.
The paper as it passes between the perforating or slotting devices is supported
and kept flat by a roller or drum upon one of the shafts between the two per-
forating devices and a second separate roller or bar may be mounted close to
the said devices for this purpose, so that the whole width as well as the central
part of the paper is supported and kept flat.
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;-
The construction and combination with a machine for printing wall papers
and the like, of apparatus for cutting, slitting or preparing the edges thereof
ready for trimming substantially as hereinbefore described and illustrated by
the drawings annexed.
