Improvements in Wire Gauze Sampling Sieves.
We, N. GREENING & SONS LIMITED, of Crown Street, Warrington, in the
County of Lancaster, Manufacturers, and FREDERICK REYNOLDSON CROWDER,
of 3, Maiden Lane, Queen Street, in the City of London, Manufacturer's Agent,
do hereby declare the nature of this invention to be as follows:-
This invention relates to a novel method of mounting specimens of wire gauze so
that they may be tested to obtain samples showing the grade of material which
they are capable of producing.
According to this invention each specimen of gauze is attached to a backing of
card board over a suitable opening therein by means of staples or other suitable
fasteners and upon this backing is placed a second layer of cardboard having in it
an opening corresponding with the opening in the backing, the two layers of card-
board being secured together for instance by means of glue and pressure in such a
manner that the wire gauze specimen has its edges enclosed between the two
cardboard layers, the central portion being exposed.
Several specimens of wire gauze may be arranged on a single mount and may
serve as part of the ornamentation of a show card or each specimen may have a
separate mount.
In conjunction with our wire gauze specimens we employ a detachable rim of
sheet metal or the like adapted to fit into the hole made in the card on one side
of the gauze so as to form with the gauze a sampling, which rim can be made
common to any number of specimens.

Improvements in Wire Gauze Sampling Sieves.
We, N. GREENING & SONS LIMITED, of Crown Street, Warrington, in the
County of Lancaster, Manufacturers, and FREDERICK REYNOLDSON CROWDER,
of 3, Maiden Lane, Queen Street, in the City of London, Manufacturer's Agent,
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 :-
This invention relates to a novel method of mounting specimens of wire gauze
so that they may be tested to obtain samples shewing the grade of material which
they are capable of producing.
According to this invention each specimen of gauze is attached to a backing of
cardboard over a suitable opening therein by means of staples or other suitable

page_text: fasteners and upon this backing is placed a second layer of cardboard having in it
an opening corresponding with the opening in the backing, the two layers of card-
board being secured together, for instance by means of glue and pressure, in such a
manner that the wire gauze specimen has its edges enclosed between the two
cardboard layers, the central portion being exposed.
In conjunction with our wire gauze specimens we employ a detachable rim of
sheet metal or the like adapted to fit into the hole made in the card on one side of
the gauze so as to form with the gauze a sampling sieve, which rim can be made
common to any number of specimens.
To enable our invention to be fully understood we will describe the same by
reference to the accompanying drawing, in which :-
Figure 1 is a plan of a wire gauze sampling sieve made according to our
invention:
Figure 2 is a section on the line 2-2 Figure 1:
Figure 3 is a plan of the detachable sheet metal rim; and,
Figure 4 is a section on the line 4-4 Figure 3.
a is the cardboard backing and b the opening thereof. c is the gauze specimen
secured over the opening 6 to the backing a by means of staples or other suitable
fasteners and d is the second layer of cardboard which is secured to the layer a by
means of glue and pressure, for example, so as to securely retain the wire gauze
specimen c in position over the opening b. This layer d is also formed with an
opening corresponding with the opening in the layer a as clearly shewn in
Figure 2.
e is the sheet metal detachable rim adapted to fit into the hole b made in the
card a on the upper side of the gauze specimen c, as clearly shewn in Figure 2, so
as to form with the gauze a sampling sieve.
Several specimens of wire gauze c may be arranged on a single mount a and may
serve as part of the ornamentation of a show card; or each specimen c may have a
separate mount a as shewn in the drawing. It will be obvious that one rime can
be made common to any number of specimens of gauze c.
Although I have described my invention as applicable to mounting specimens of
wire gauze, it will be obvious that it is equally applicable to mounting specimens of
perforated metal for obtaining samples of material.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. A wire gauze or perforated metal sampling sieve consisting of a mount of
cardboard having an opening covered by a specimen of gauze or perforated metal
secured to the said cardboard mount and adapted to have a detachable rim of sheet
metal fitted into the opening of the cardboard mount, substantially as, and for the
purpose, herein before described.
2. The manufacture and use of the improved wire gauze or perforated metal
sampling sieve herein before described and illustrated in the accompanying
drawing.
