Improvements in Strainers or Sieves for Various Purposes.
We, HUGH MCCLELLAND trading as McClelland Brothers of Cambridge
Street, in the City of Birmingham, Merchant, and JOSHUA HENDERSON, of
Heneage Street, Birmingham aforesaid, Manufacturer, do hereby declare the
nature of this invention to be as follows:-
-
Our invention relates, in the one part, to improvements in strainers or sieves for.
various purposes, such for example as milk, gravy and brewers strainers, cullenders,
sieves, and other like apparatuses for the draining of liquids or for the interception
of solid and suspended matter from liquid and semi-liquid substances, and in.
another part, to the production or manufacture of a part of the said apparatuses.
The primary object of our invention is a detachable or loose bottom, so that one
body vessel can be used with any number of varying meshed bottoms or strainers,
hence a saving in the number of vessels required.
In carrying out our invention in connection with an ordinary strainer or sieve,
we take a vessel with an open and socketted bottom, that is, an open bottom,
slightly contracted and rabated, so as to form a flange or neck upon which, or
within which, a flange of the strainer bottom tightly comes. If the flange or short.
neck of the strainer bottom comes within the inside of the flange of the open
bottom, then a stop collar is formed upon the outside of the said flange.
By employing a number of false, loose or detachable reticulated bottoms, each
varying in the mesh, one body vessel can be employed for a variety of strainings.
Instead of the loose strainer bottom being secured to the flange by frictional
contact only, we may impress screw threads within the opposed flanges of vessel.

bayonet or other joint may be employed for securing the bottom in position.
Or the loose bottom may be dropped into the vessel socket-wise from the inside
and fit tightly within a taper socket at the open bottom of the vessel.
In carrying out the manufacture of the detachable bottoms according to the
second part of our invention, the wire gauze or mesh is cut into circular discs, of a
size rather larger than the bottoms to be made, and the edges of the said discs are
turned down all round, forming flanges of a suitable depth. The socket sides are
formed from strips of sheet metal, bent into the desired circular form and whose
lower edge parts are swaged or turned up upon themselves, forming all-round
pockets or annular recesses for the reception of the turned-down edges or flanges
of the wire gauze, upon which, when in position, the metal of the socket sides is
tightly closed, hence the connection of mesh and socket together.

We propose that the boundary edges of the turned-up or swaged parts, forming
pocketted walls, should be beaded, to prevent the cutting of the wire mesh or·
reticulated bottom on the closing of the walls forming the flange.
As a further form, the edges of the wire gauze mesh may if necessary be turned
upwards, and be embraced between the walls of the outer ring and those of an
inner and fitted ring.

We, HUGH MCCLELLAND trading as McClelland Brothers of Cambridge
Street, in the City of Birmingham, Merchant and JOSHUA HENDERSON of
Heneage Street, Birmingham aforesaid, 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 :---
Our invention relates, in the one part, to improvements in strainers or sieves for
various purposes, such for example as milk, gravy and brewers strainers, cullenders,
sieves, and other like apparatus for the draining of liquids or for the interception
of solid and suspended matter from liquid and semi-liquid substances, and in
another part, to the production or manufacture of a part of the said apparatuses.
The primary object of our invention is a detachable or loose bottom, so that one
body vessel can be used with any number of varying meshed interchangeable
bottoms or strainers, hence a saving in the number of vessels required.
In carrying out our invention in connection with an ordinary strainer or sieve,
we take a vessel with an open and socketted bottom, that is, an open bottom,
slightly contracted and rabated, so as to form a flange or neck upon which, or
within which, a flange of the strainer bottom tightly comes. If the flange or short.
neck of the strainer bottom comes within the inside of the flange of the open
bottom, then a stop collar may be formed upon the outside of the said flange.
By employing a number of loose or detachable and interchangeable reticulated
bottoms, each varying in the mesh, one strainer body can be employed for a variety
of strainings.
Instead of the loose strainer bottom being secured to the flange by frictional
contact only, we may impress screw threads within the opposed flanges of vessel
and loose bottom, so that the said loose bottoms may screw on and off. Or a
bayonet or other joint may be employed for securing the bottom in position.
Or the loose bottom may be dropped into the vessel socket-wise from the inside
and fit tightly within a taper socket at the open bottom of the vessel.
In carrying out the manufacture of the detachable bottoms according to the
second part of our invention, the wire gauze or mesh is cut into circular discs, of a
size rather larger than the bottoms to be made, and the edges of the said discs are
turned down all round, forming flanges of a suitable depth. The socket sides are
formed from strips of sheet metal, bent into the desired circular form and whose
lower edge parts are swaged or turned up upon themselves, forming all-round
pockets or annular recesses for the reception of the turned-down edges or flanges
of the wire gauze, upon which, when in position, the metal of the socket sides is
tightly closed, hence the connection of mesh and socket together.
The outside walls of the annulus or ring have a stop beading formed upon it for
limiting the socketting of the bottom.
We propose that the boundary edges of the turned-up or swaged parts, forming
hollow walls, should be beaded, to prevent the cutting of the wire mesh or
reticulated bottom on the closing of the walls forming the flange.
Figure 1 of the accompanying drawings represents a vertical section of a strainer
fitted with a loose and interchangeable bottom and made according to one part
of my improvements.
Figure 2 represents an underside plan of Figure 1.
Figure 3 represents a top-side plan of one form of my invention, showing the gaps
and the overhanging ends of the cross bar securing the loose and meshed bottom
with the open bottom of the strainer body.
Figure 4 represents a part vertical section of the strainer upon an enlarged

page_text: scale, in order to show more clearly the means of connection between body and
bottom.
Figure 5 is a part vertical section of the strainer body separately and Figure 6
is a like view of the bottom separately.
Figure 7 represents upon the same scale as Figures 5 and 6, a part of the edge
of the open bottom of the body surrounding one of the gaps.
Figure 8 represents a blank or strip of metal from which the rim of the strainer
bottom is made, as represented in section in Figure 9.
The same letters of reference indicate corresponding parts in the several figures
of the drawings.
a is the strainer body, with a flange a', at its open bottom a², which fits within a
socket 6, of the open top 6', of the strainer bottom b, fitted with wire gauze or other
reticulated medium 6. The said bottom is detachably connected by the slightly
elevated ends c', of a rod c, directed diametrally across the mesh and with the said
ends passing through the gaps 6, of a flange 65, standing out from the inside edge
of the open bottom of the strainer body. By taking hold of the loose strainer
bottom by the handle bar 66, and passing the ends c', through the gaps 6, and then
rotating the former, the said ends c', are removed from the gaps and slid circularly
round and over the flange into the position as represented in Figure 3.
The strainer bottom b, is made up from a long blank of thin sheet metal
Figure 8, of a length suitable for making a ring of the required diameter, whose
edges and are turned inwards into the hollow cross section represented in
Figure 9, with the metal folded upon itself, leaving a gap be, wherethrough the
edges 6' of a cut-out wire gauze strainer bottom 63, are inserted and then cupped
between the walls, as best seen in Figures 4 and 6.
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:
First. A strainer, sieve, cullender or like appliance having a loose and inter-
changeable strainer bottom, with the socket of the one part adapted to fit onto or
over the flange of the other part, substantially as and for the purpose described
and set forth.
Secondly. In strainers, sieves, cullenders and like appliances having detachable
and interchangeable bottoms, securing the said bottoms to the strainer body by the
ends of a securing rod or equivalent carried by the bottom passing through gaps
in, and resting upon the topside of, an inside flange of the said body part,
substantially as and for the purpose described and set forth.
Thirdly. In strainers and like appliances as referred to in the first claim,
securing the bottom to the body part by impressing screwings or wormings,
substantially as described.
Fourthly. In strainers, sieves, cullenders and the like, making the rims of the
bottoms from sheet metal, and affixing the strainer medium thereto, by the way
herein described and set forth..
