Improvements in and relating to Liquid Strainers, Applicable for
Culinary and other Purposes,
We, WILLIAM FERGUSON, and WILLIAM HOOD, both of Swan Street, Brechin,
Forfarshire, Ironmongers, do hereby declare the nature of our invention to be as
follows:-
Our Invention has reference to improvements in portable liquid strainers or
"searches" applicable for culinary, milk straining, and other purposes, and which will
filter or strain the substances placed in the strainers in a simple and more effectual
manner than heretofore.
And the nature and novelty of our improvements consist in constructing
liquid strainers with duplex sieves or perforated bottoms, the one sieve or
perforated bottom forming part of, or attached to, the straining vessel, and
the other sieve placed a short distance from it and made portable or removable
from the outside.
In carrying our improvements into practice, under one arrangement we make a bowl
shaped vessel, (but it might be of square, or other polygonal shape) punched or per-
forated in the contracted bottom part but it might be a bottom formed of wire
sieves or gauze fixed liquid tight in it. A vertical socket or web rim would be
soldered or formed round the outer circumference of the under surface of the perforated
bottom, to which would be soldered or otherwise secured, at a short distance below
the perforated bottom a vertical beveled rim with a narrow annular flange on its inner
upper surface at the part secured to the bottom rim. A removable wire sieve, with
annular flange soldered or secured to it, is inserted from below and rests on the under
surface of the inner flange formed on the beveled vertical rim and is secured in
this position by an inner and lower jointing rim or spigot which is hinged or secured
on the one side by pins passing through holes, or otherwise to the inner surface of the
vertical rim. The lower jointing rim would be secured at the opposite side to the
hinges by an eye and pin, latch or other fastening, under the projection of the outer
rim socket and which can be removed when this jointing rim and the lower portable

page_text: sieve are desired to be removed for cleaning, or for using the strainer with only the
single stationary perforated bottom or wire sieve. These vessels can thus be used
either as double or single strainers, according to the culinary or other purpose for
which they are to be used, and may have different sets of portable sieves with finer
or coarser meshes for the particular purposes desired.
A handle would be formed on or secured to the one side preferable the lower
part of the strainers for carrying them about, and they would be formed with
a kneed projecting piece on the opposite side in line with the handle for resting on
this and the handle when used for filtering or straining purposes, and which would
support and steady the strainer on the top of the vessel into which the liquids
were to be strained and could be used for hanging or securing them to shelves or other
attachments when not in use.

Improvements in and relating to Liquid Strainers, Applicable for
Culinary and other Purposes.
WO, WILLIAM FERGUSON, and WILLIAM HOOD, both of Swan Street, Brechin,
Forfarshire, Ironmongers, do hereby declare the nature of our said invention and
in what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement in writing, reference being had to the
accompanying Sheet of Drawings, and to the letters and figures marked thereon, that
is to say:-
Our Invention has reference to improvements in portable liquid strainers or
"searches" applicable for cooking or culinary, milk-straining, and other purposes, and
which will filter or strain the substances placed in the strainers in a simple and more
effectual manner than heretofore.
And the nature and novelty of our improvements consist in constructing liquid
strainers with duplex sieves or perforated bottoms, the one sieve or perforated bottom
forming part of, or attached to, the straining vessel, and the other sieve placed a
short distance from it and made portable or removable from the outside.
And in order that our said invention, and the manner of performing or carrying the
same into effect or practice may be properly understood, we have hereunto appended
an explanatory Sheet of Drawings, in which the same reference letters are used to
indicate corresponding parts in all the figures where shown.
Figure 1 is a perspective view of one construction of liquid strainer as fitted with
our new duplex bottom sieves or strainers a a³, and Figure 2 is an inverted plan view
of same, showing half of the lower wire strainer a¹ and a corresponding part of
the upper perforated bottom or strainer a. Figure 3 is an edge view and plan
respectively of the lower wire sieve or strainer a¹. And Figure 4 shows corre-
sponding views of the portable hinged rim A', which secures the lower sieve or
strainer a in position. Figure 5 is a sectional elevation of the liquid strainer or
vessel shown in Figure 1, and Figure 6 is a corresponding section of a slightly
modified shape or construction of liquid strainer or vessel from that shown in
Figure 5.
Referring to these Drawings:-In carrying our improvements into practice under
this arrangement we make a bowl shaped vessel A, but it might be with conoidal
sides as shown in Figure 6, or of a square, or other polygonal shape, punched or
perforated in the contracted bottom part a but it might be a bottom formed of wire
sieves or gauze such as shown in Figure 3, fixed liquid tight in the bottom of the
vessel A. A vertical socket or web rim A¹ is formed, soldered or otherwise secured
round the outer circumference of the under surface of the perforated bottom a to
which is soldered or otherwise secured, at a short distance below the perforated bottom
a vertical bevelled rim A" with a narrow annular flange on its inner upper surface
at the part secured to the bottom rim to form a space a' between the two

page_text: sieves a a', as shown in Figures 1, 2, and 5; or this lower rim A" may be directly
secured to the lower part of the vessel A, and be formed with a space a between the
sieves a a¹ as shown in Figure 6. A removable wire sieve a' Figure 3 with annular
jointing ring a" soldered or secured to it, is inserted from below and rests on the
under surface of the inner flange A" formed on the bevelled vertical rim A¹ and is
secured in this position by an inner and lower portable jointing ring or spigot A
Figure 4, which is hinged or secured on the one side by pins 6 passing through holes 61
or other equivalent to the inner surface of the vertical rim A". The lower jointing
rim A² is secured at the opposite side to the hinges by a sliding wire locker and eyes
at or it might be by a latch or other fastening on the projection of the outer rim
socket A and which can be removed when this jointing rim A2 and the lower
portable sieve a¹ are desired to be removed for cleaning, or for using the strainer with
only the single stationary perforated bottom or wire sieve a. These vessels can thus
be used either as double or single strainers, according to the culinary or other purpose
for which they are to be used, and may have different sets of portable sieves a¹ with
finer or coarser meshes for the particular purposes desired.
A handle is formed on or secured to the one side preferably the lower part of the
strainers A as shown in Figures 1, 2, and 5 for carrying them about, and they would
be formed with a kneed projecting piece b³ on the opposite side in line with the
handle for resting on this and the handle when used for filtering or straining
purposes, and which would support and steady the strainer A on the top of the
vessel into which the liquids were to be strained and could be used for hanging
or securing them to shelves or other attachments when not in use. Or these
strainers may be fitted with simple handles at the upper part of the vessel as shown
in Figure 6.
at
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed we declare that what
we claim is:
-
First. The constructing of liquid strainers with duplex sieves or perforated bottoms,
substantially as and for the purposes herein set forth.
Second. A liquid strainer, comprising the combination of an outer vessel A with
perforated hottom or sieve a having a flange rim A¹ A" and portable or removable.
sieve a¹ a", inserted between this joint rim A¹ A", and a lower hinged jointing rim A³
or other equivalent, substantially as and for the purposes herein described, in reference
to and shown in the accompanying Drawings.
