PROVISIONAL SPECIFICATION.
A New or Improved Wire-cloth for Papermaking Machinery.
GEORGE HENRY MAY Wire Weaver 273 Dalmarnock Street Parkhead Glasgow
Scotland do hereby declare the nature of this invention to be as follows:-
My invention relates to wire-cloth for papermaking machinery; pliable in the
direction of its running and rigid breadthwise; and consists of interlocking a
number of helical wires (preferably helices of an alternate right and left hand
twist) together by means of straight wires; the straight wires serving the purpose
of stiffening the web accross and weaving the helices together; and so on untill a
continuous and practically seamless web is formed; having great rigidity accross its
width and great flexibility in its length; to give an even and smooth surface the
web is or may be compressed between rollers.

A New or Improved Wire-cloth for Papermaking Machinery.
I, GEORGE HENRY MAY of 273 Dalmarnock Street Parkhead Glasgow Scotland
Wire-weaver 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 relates to a new or improved wire cloth for paper making machinery,
and has for its objects the constructing of a web in such a manner as to obtain a
great amount of pliability in the direction of its running, and rigidity breadthwise.
In order that my invention may be clearly rendered, reference may be had to the
accompanying sheet of drawings, in which Fig. 1 is a plan view of a piece of my
improved cloth, and Fig. 2 is a side view of the same after being flattened by
compression. Similar letters of reference are used to indicate like parts in the
sheet of drawings.
In constructing a paper machine wire cloth according to my invention I interlock
a number of helical wires (A.) together-preferably helices of an alternate right
and left twist by means of straight wires (B.). (C) represents the manner in
which the helices are interlocked by inserting and shooting across its width the
straight wire "B." the said straight wires serve the purpose of stiffening the web
across and weaving the spirals together, and so on until the required length of web
is woven, when I form it into a practically seamless belt by taking the two free ends
of the web and coupling them together by the same means as I employ in weaving
the web itself thereby ensuring the same continuity of pattern in that particular
part. The manner of forming the said seam is shown in Fig. 1 at "D" where the
helices (AA) representing the two free ends of the web are brought together and
interlocked by means of the straight wire "B¹." To give an even and smooth
surface the web is or may be compressed between rollers when the helices will take
the formation as shown at Fig. 2.

page_text: 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.
First. The general arrangement and combination of parts constituting the new or
improved wire cloth for papermaking machinery, substantially as described.
Second. A wire cloth for papermaking machinery composed of helices and
straight wires so interwoven as to give a great amount of flexibility in its length,
and rigidity in its width, substantially as herein described and shown.
Third. A wire cloth for papermaking machinery, in which the coupling of the
two free ends of the web together to form a continuous belt, does not differ from
the method of constructing the web itself, or alter its continuity of pattern in that
particular part, substantially as herein described with reference to the appended
sheet of drawings.
