Improvements in Paperhangings.
CHARLES GREEN, JUNR., 55, Red Lion Street, Holborn, London, W.C.,
Engineer, do hereby declare the nature of this invention to be as follows:-
1
My invention is an improvement on my Specification No. .21,055, dated 1893.
I now instead of perforating, or cutting through the list, or trimming of a wall,
& ceiling covering, I reduce the thickness of the paper, by forming a narrow
groove, this groove, being formed by squeezing or crushing the paper along the
list.
In order that my invention may be carried into practical use, I use circular
discs, of steel, or other suitable metal having their edges formed so that as the
paper passes between them they reduce the thickness by forming a groove along
the list, they also make the paper at the bottom of the groove of less thickness
on one edge of the groove this allows the list or trimming to tear straight and
clean.
The discs can be mounted on a suitable frame, and fitted to the printing
machine.
What I claim as the novelty of my invention is a paperhanging, and wall, and
ceiling covering, having the list, or trimming on one or both edges reduced in
thickness by being grooved' or crushed in such a manner as to allow the list to
be easily detached by tearing, and leaving the edges straight. and clean..

Improvements in Paperhangings.
CHARLES GREEN, JUNE., 55, Red. Lion Street, Holborn, 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 an improvement on my Specification No. 21,055, dated 1893.
I now instead of perforating or cutting through the list or trimmings of a wall,
and ceiling covering, I now reduce the thickness of the paper by forming a groove
on both sides of the list (that is to say on the side with the design, and also the
side which is pasted and fastened to the wall or ceiling)-the grooves are formed
by squeezing or crushing the paper, by passing between two discs of suitable
metal.

page_text: The object of my invention is to so prepare the list or trimmings of paper
hangings, and wall & ceiling coverings in order that the said hangings, and wall
and ceiling coverings may be supplied grooved ready for trimming without the
use of shears, or the like by the paper-hanger.
My invention is to form a groove on both sides of the paper along the list (on
the front side, and also on the side which is pasted and fastened to the wall or
ceiling by thus grooving both sides of the paper it reduces the thickness between
the grooves so that when the paper is pasted by the paper-hanger the paste
moistens this thin part left by the grooving, thus allowing the list or trimming
to be easily detached by tearing and leaving the edge straight and clean.
In the stocking and handling the "pieces" or rolls of paper-hangings and
the like, in the show rooms and warehouses the list, or trimmings are liable to
become detached, to over-come this I leave a short length of the list ungrooved
this plain parti acts as a guard or shield to the remainder of the piece or roll. In
common paper-hangings, and also in some other kinds of wall, & ceiling
coverings this plain, or ungrooved part would not be required, so that the grooving
would be continued the entire length of the piece, or roll of the paper-hanging,
or wall, & ceiling covering.
The manner in which my invention is to be performed or carried into practical
effect will be readily under-stood on reference to the annexed sheet of drawings
and the following explanation thereof
Fig. 1, shows the framing 28, of the attachment fixed to a part of the end
framing A, of a machine for printing paper hangings, or similar coverings in
Fig. 2, at B, is shown a part of the bed roller against which the printing takes
place. Fig. 2, also shows a view of the attachment across the printing-machine
with a part of the attachment shown in section through the bearings for the
shafts 1, 12, 19, & 30. The gear wheels for driving the shafts are also shown in
the same section at 16, 20, 21, 22, 26, and 32. At C, Fig. 2, is shown the large
gear wheel of the printing machine having the wheel D of the attachment geared
into it.
•
The wheel D, through the suitable gears, 16, 20, and 32, drives the shafts 12,
and 19, from which by the gears 9 & 13, the grooving discs 10, and 18, are driven.
Figs. 1 & 2, show the grooving discs 10, and 18, fitted on the attachment. The
bottom disc 18, can be moved along the shaft 19, and clamped to the shaft at any
part required, so as to allow for the difference in the width of the designs on the
printing rollers. The top grooving disc 10, is mounted on one end of a short
shaft, which works in a bearing fixed to the arm 14, on the other end of this short
shaft is keyed the gear 9, this gear wheel 9 is driven by the gear wheel 13, which
is mounted on the shaft 12. Fitted to this gear wheel 13, is a feather working
in a groove made the entire length of the shaft 12, so that the gear 13, is driven
when at any part of the shaft, 12, thus when is is required to adjust the grooving
dise 10, over the lower grooving disc 18, the arm 14, is moved along the shaft, I,
and the gears 13, and 9, are moved with it, as shown in Fig. 1, at 12, the whole
can be clamped in place on shaft I by the clamping screw at 5, Fig. 2. At the
bearing end of the arın 14, is fitted an adjusting screw 11, which bears against
the beam 4, at 3. On the head 7 of this adjusting screw 11, is a suitable graduated
index fitted with an index pointer S. By this adjusting screw and index the
arm 14, with the grooving disc 10, attached can be adjusted to allow the proper
distance between the grooving discs, 10, and 18. If the grooving is to be con-
tinuous the beam 4, which is attached to the shaft I, at 6, would be a fixture with
the framing 14, of the attachment. But when a short length of the list, or trim-
ming is to be left ungrooved, a lever arm 15, is keyed on the end of the shaft I
at 2, and on the other end of the lever 15, is fitted a small roller 27,
pressing against the cam 25, which is keyed to the shaft 30, this
cam shaft 30, is driven by suitable gears 26, 22, 21, 20, 16, and
D. so that when the grooving dises 10, and 18, have revolved a certain
number of times the part 24 of the cam 25, comes under the roller 27,

page_text: "
this allows the lever arm 15, to slightly move the shaft I, thus the beam 4 rises,
and the pressure is removed from the adjusting screw 11, at 3. Then as the
shaft 30, continues to revolve, the cam 25, again forces the lever arm 15, back
at 27-and thus the pressure beam 4, acts upon the screw 11, at 3, as before. The
adjusting screw 11, bearing against the pressure beam at 3, allows the grooving
discs, 10, to be adjusted independently of each other, and also allows any number
of sets of grooving discs to be fitted on the spindles 1, 12, and 19 as in the case
of borders, or friezes when being made or printed on the machine to which the
attachment is fixed. The dotted line in Fig. 1, shows the hanging passing
between the grooving discs and than round a drum 29, which is merely to guide
the hanging to the bed-roller of the printing machine, as shown by the dotted
line. There can also be a drum fitted to guide the paper to the grooving discs
when required. These drums revolve by the material passing over them. Fig. 3,
shows a piece," or "roll of paperhanging, at 33, is shown the edging or trim-
ming, and the groove formed along the edge of the design at 34, at 35 is shown the
trimming plain, or ungrooved 36 being the print of the design on the paper only.
This ungrooved part 35, is the guard, or shield, 37, being the side which is pasted,
at 38, is shown the groove formed on this side, the said groove is in register
with the grooving on the design side 36. Fig. 4 is a section through the line
at X, X, in Fig. 3. At 39 is shown the shape of the top grooving disc, and 40,
the bottom grooving disc. These discs form the grooves in the paper the shape
shown at 41 and 42. In Fig. 5, is shown the shape of the grooving that can be
used on thick embossed coverings, 43, being the top grooving disc, and 45, the
bottom, by thus forming the groove different on the side 37, which is the pasted
side. When the trimming is detached, it leaves a bevelled edge, this enables
the paper hanger to make a very close joint when butting" the edges, and also
at Fig. 6, is shown the grooving dises mounted at an angle for the same purpose.
Fig. 7, shows the shape of the grooves made by the grooving discs 46 & 47,
when the top, & bottom discs are the same shape.
I am so far as I am aware the first to groove the edging or trimming of paper-
hangings and wall and ceiling coverings-hence I do not consider myself limited
to the precise form of the grooves, or the grooving dises herein shown, for various
changes may be resorted to without departing from the spirit and scope of my
invention.
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). A paper hanging or wall and ceiling covering having the list or trimming
grooved on one, or both sides of the paper, and on one or both edges, ready for
trimming by tearing, substantially as described.
"
2). A piece or roll of paperhanging or wall & ceiling covering having
the list, or trimming, grooved on one or both sides of the paper, and on one, or
both edges, and having a short length of the said list ungrooved, so that this un-
grooved part shall form a "guard or shield for the part of the piece, or roll
which is grooved-substantially as herein before described.
::
3). The construction and combination, with a machine for printing or emboss-
ing paper-hangings, or wall and ceiling coverings, of an apparatus, or attachment
for grooving and preparing the lists or edges of wall & ceiling coverings, ready
for trimming, at the time of printing or embossing-substantially as described
and shown in the drawings annexed.
