1, William GREEN, Paper and Bank-note Moulds, Dandy Roll, and Machine
Wire Manufacturer, 98 Albany Road, Old Kent Road, in the County of Surrey,
do hereby declare the nature of this invention to be as follows:-
Whereas the moulds now in use, in connection with the Sembritzki patent.
machine (No, 4077-of Aug. 22/83) for mechanically making hand-made paper,
being a part and parcel of the machine itself, necessitate the long and expensive
opperation of un-sewing and un-soldering the sheets of the moulds ("laid" or
"wove gauze) and re-sewing and re-soldering on other sheets, for each change of
denomination or watermark the paper maker has to make I, by this invention
obviate the necessity for all this sewing and un-sewing, and soldering and un-
soldering of the sheets by supplying other light metal moukl-frames with the
required sheets already attached thereto, which light frames can be affixed on the
top of the moulds now in use in a few minutes by means of 6 or 8 set-screws, and
removed in a few minutes for frames of other denominations or watermarks to take
their place. The moulds now in use will still be used but instead of the sheets
being fastened immediately on to them, they will be used as a strong skeleton
foundation to take the light metal moulds described above.
I also make a provision for the spring deckle or dividing-wires-riz.; for the deckle
wires, which divide the mould into sheets, to go down by means of a spring level
with the surface of the mould when the mould reaches the couch-roll in order to
prevent the deckle-wires from injuring the felt on the couch-roll, and to admit of
the paper-maker having thicker deckle-wires for thick paper than he would now be
able to use.
What I claim therefore by this Patent is the use of any kind of mould which
by any means, is worked on the top of the mould now in use in connection with the
Sembritzki machine for mechanically making hand-made paper; and the use of
spring deckle or dividing-wires connected with any moulds for making paper; and
the use of metal moulds in connection with any kind of machinery for mechanically
making hand-made paper.

COMPLETE SPECIFICATION.
Improvements in the Moulds used on the Sembritzki Patent Machine
and any Machine for Mechanically Making Hand-made Paper, and
in other Paper-making Moulds.
I, William GrEEN 98 Albany Road Old Kent Road London S.E. Dandy
Roll, Bank-note Mould and Paper-machine Wire 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, reference
being made to the accompanying drawings:-
Whereas the moulds (A) now in use in connection with the Sembritzki patent
machine No. 4077-A.D. 1883 for mechanically making hand made paper, being a
part and parcel of the machine itself, necessitate the long and expensive operation
of un-sewing and un-soldering the sheets (B) of the moulds (“laid”

or Wove

page_text: gauze) and re-sewing or re-soldering on other sheets, for each change of denomina-
tion or watermark the paper maker has to make; 1, by this invention obviate the
necessity for all this sewing and unsewing and soldering and unsoldering of the
sheets by supplying other light metal mould frames (C) with the required sheets (B)
already attached thereto, which light frames can be affixed on the top of the
moulds A. now in use, in a few minutes by means of a few T shape screws and
nuts (D) in the following manner :-The mould C is composed of a number of thin
flat ribs (C) standing up edgeways, about an inch apart or according to require-
ments and held together by 1" or other size rod-wire (C2) passed through
perforations in the ribs (C)-the ends of the ribs and the ends of the rod-wires
being fitted into slots made in the outside frame of the mould C-the whole being
soldered together to make it rigid. Then any required number of T shape
screws (D) are used-the screw part passing down between two of the ribs C¹,
between two of the rods C³, so that the head of the T shape screw D rests on four
of the rods C²; then one or more plates or washers (D2) are placed on the under
side of two of the strong ribs of the mould A, then by a nut (wing or other kind) DI
put on to the T shape screw D, the mould C can be fastened down as tightly as
required on to the mould A. The mould C can also be removed in a few minutes
for frames of other denominations or watermarks to take their place. The
moulds (A) now in use will still be used, but instead of the sheets (B) being
fastened immediately on to them, they will be used as a strong skeleton foundation
to take the light metal moulds (C) described above.
and
I also make a provision for spring deckle or dividing wires viz., for the deckle
wires or plates (E) which divide the mould into sheets or divisions, to go down
by means of a spring (F) level with the surface of the mould when the mould
reaches the couch-roll in order to prevent the deckle wires from injuring the felt
on the couch-roll, and to admit of the paper maker having thicker deckle-wires
or plates for thick papers than he would now be able to use.
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
The use of any kind of mould which by any means is worked on the top of the
mould now in use in connection with the Sembritzki machine for mechanically
making hand-made paper; and the use of spring deckle or dividing wires or plates
connected with any moulds for making paper.
