PROVISIONAL SPECIFICATION.
Improvements in Paperhangings.
CHARLES GREEN Junr. Engineer of 52, Great Coram Street, London, W.C.
do hereby declare the nature of this invention to be as follows:-
My invention is to do away with the objectionable features heretofore existing
in paper-hangings, and wall & ceiling coverings, and for the removal of the list or
trimmings thereof by the paperhanger more expeditiously than can be done with
the ordinary paperhangers shears.
My invention is to slit, punch, cut through, or perforate along the list, or
trimmings on one, or both edges of the paper in such a manner that the list, or
trimmings can be easily detached by tearing when required for use.
I use a circular
In order that my invention may be carried into practical use,
disc of steel with a cutting edge made so as to leave the bars, or portions of the
paper between the perforations as small as possible, the said disc may be set at an
angle if required for thick papers, I also roll the bars left by the cutting disc with
a blunt thin edged disc. This will allow the list to retain the bars, and thus leave
the edges of the hangings after the list has been separated by tearing, straight
and clean.
The discs can be mounted on any suitable frame & fitted to the printing
machine.
What I claim as the novelty of my invention is a paperhanging, & wall, &
ceiling covering with a perforated list or trimming, on one or both edges, and
which can be easily detached by tearing, and leaving the edges straight and
clean.

COMPLETE SPECIFICATION.
Improvements in Paperhangings.
CHARLES GREEN Junr. 52 Great Coram Street, London W.C. Engineer, 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 :-
My invention is to do away with the objectionable features heretofore existing
in paperhangings & wall and ceiling coverings and for the removal of the list, or
trimmings thereof by the paperhanger more expeditiously than can be done with
the ordinary paperhanger's shears.
My invention is to slit, cut through or perforate along the list or trimmings on
one or both edges of the paper in such a manner that the list or trimmings can be
easily detached when required for use, by tearing.
In order that my invention may be carried into practical effect I use a circular
disc of steel, (tempered) with a cutting edge made so as to leave the bars, or
portions of the paper between the perforations as small as possible.

page_text: Fig. 2. shows on an enlarged scale parts of the cutting edges of the discs, with
a piece of the edges removed at P. and also where the steel is filed, or cut away
from C to R, so as to form a knife edge from, C. to D.
The shape of the plain, or unbevelled side of the discs T. & O. (Fig. 4.) is shown
on an enlarged scale at T. (Fig. 5.). A side view of T & O. is shown in Fig. 6.
and also the plain disc N. Fig. 7. shows the bevel side of top cutting disc T. and
also shows the front side of the plain disc of steel N.
Figs. 4, 5, 6, & 7. shows the shape of the circular knife edge discs, of steel T,
and O., also where the parts of the edges are cut away at P.
The plain circular disc of steel N. with its edge touching the bevel edge of
the upper cutter T. helps to form the shape of the perforations as shown at R
Fig. 3.
The length of P. to P. (Fig. 5.) of the cutting or sliting edge of the
discs T. & O. can be of any length, and can be that, which is found most suitable for
the kind of paper being perforated. There can be also, any number of the parts
marked D. D, C, C, (Fig. 5), made in the knife edge of discs T. and O. to suit the
diameter of cutters used.
The circular knife edge disc of steel T (Fig. 4), is mounted on a suitable spindle
driven by D Fig. 1. The circular knife edge disc O (Fig. 4), and the plain
circular disc of steel N. (Figs. 4. 6. & 7.) are mounted together on a suitable
spindle, and driven by E. Fig. 1. The pieces of the edges removed from the
discs T. & O, as shown at P. Fig. 4, will allow a portion of the paper to remain
uncut, the other parts of the edges of the cutters, or discs T. & O. slit or perforate
the paper as shown in Fig. 3. at R. in such a way as to leave a straight edge when
the list is separated by pulling, or tearing. The list, or trimming, may be more
easily removed after the paper has been wetted with paste.
Some papers being thicker than others may require the bars to be rolled with
blunt discs and the cutters may be set at an angle if necessary.
The cutters T. & O. are mounted on spindles of the same length, as the width
of the printing machine, and are adjustable along the spindles for the different
widths of papers required to be perforated. The ends of the spindles work in
suitable bearings, and can be easily removed for the purpose of sharpening the
cutters.
The spindles with cutters attached are driven by the gearing in Fig. 1 (B).
The wheel B gears with C, and C. drives D. which is attached to the spindle of
the top set of cutters; B also drives and gears with E, (which is attached to the
spindle of the bottom set of cutters,) D. by this means is adjustable, and can be
raised, or lowered to suit the different thicknesses of papers, B. is driven by a band
or strap from A. The band passes over the tightening wheel F.
A is a wheel for band or strap, and is fixed to a spindle G. which runs in
suitable bearings K. and at the other end of the spindle G, is a small friction wheel I,
which is movable along the spindle G. by the small adjustment wheel M. and screw L.
The friction wheel I is driven by the driving wheel H. By moving the friction
wheel I. from the centre of the wheel H. the speed of A. which drives D. and E,
can be regulated to suit the speed of the paper without stopping the machine.
There may be two, or more complete sets of B. C, D, & E, with their spindles,
bearings, and cutters, fitted on the printing machine, so that when the edges of one
set of cutters are blunted another set could be put into gear without stopping the
printing machine.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
(1.) A perforated list, or trimming to paperhangings, and wall and ceiling

page_text: (2.) The arrangement of circular cutters with parts of the edges removed, the:
said arrangement to be attached to the printing machine, so that the printing, &
perforating may be performed at the same time.
Dated this Third day of August 1894.
