Improvements in Hand Sieves.
I, WILLIAM BARNS Junior, Christopher Works Chalton Street, London, Metal
Worker do hereby declare the nature of this invention to be as follows:-
According to this invention a hand sieve is made entirely of light steel the wire
mesh work being replaced by perforated sheet steel and the wood band by a light
steel frame so made that when the bottom is worn out it can be readily removed
and a new one substituted therefor. Or the bottom and frame may be made in one
piece if preferred.

I, WILLIAM BARNS Junior, Christopher Works, Chalton Street, London, Metal
Worker, 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 :-
According to this invention a hand sieve is made entirely of light sheet metal,
preferably steel, the ordinary wire mesh-work bottom being dispensed with and a
removable adjustable perforated sheet metal bottom substituted therefor, while the
ordinary wooden band is replaced by a metal band having a beaded edge or other
equivalent guard formed thereon or fitted thereto, and which hand, if desired, may
also be perforated so as to afford additional screening area. The perforations may
any suitable size and shape and arranged in any convenient manner consistent
with retaining the requisite degree of strength. The bottom may be fastened to
the band by wires or by one or more angle irons, or in any other convenient manner
to allow of its being readily removed and replaced.
be of
The sieve may be circular or of any other form, and may be made of black,
galvanised or other artificially coated steel, or of any other suitable sheet metal.
By my invention a very considerable saving is effected in the cost of manufacture
while hand sieves so made are far more durable than those hitherto in use for the
following reasons, vizt.
Firstly. Owing to the saving in wear and tear effected by substituting a
perforated sheet metal bottom for the ordinary wire work. Secondly. Owing to
the indestructibility of the sheet metal band as compared with the ordinary wooden
one and Thirdly. Owing to the facility with which the perforated bottom can be
replaced by one having finer or coarser perforations, or by a new one when worn
out such substitution being effected with little trouble and at trifling cost.
I prefer to attach the bottom to the band by two wires of suitable strength one end
of each wire having a head or stop while its other end is threaded to receive and is
fitted with a screw-nut. The edge of the perforated bottom is turned up all round

page_text: so as to form a rim or flange of a convenient depth wherein suitable equidistant
holes are made while corresponding holes are made in the lower part of the metal
band. When the perforated bottom is fitted therein it is adjusted so as to bring
such two series of holes opposite each other. The wires are then passed through
the holes at right angles to each other and the screw nuts fitted and tightened up
thus securing the perforated bottom in the band and keeping it in position. Or
the rim or flange round the bottom may be dispensed with and likewise the wires
and in lieu thereof one or more angle iron or angle irons may be rivetted or
otherwise fastened to the bottom of the metal band on the inside and the perforated
bottom secured thereto by screws and nuts or their equivalents. Or the bottom
and band may be fastened together. in any other convenient manner.
DRAWINGS.
In the accompanying drawings similar letters of reference indicate corresponding
parts.
Figures 1 and 2 shew a plan of the underside and, a transverse section taken on
the line A. B. Fig. 1, of a hand sieve made according to my invention the
perforated bottom being attached to the band, by means of wires in the manner
hereinbefore described-a are the wires- the stops or heads thereon-c the screw
nuts on the threaded ends-d the perforated sheet metal bottom-f the metal band
with beaded edge g.
Figures 3 and 4 shew corresponding views of a similar hand sieve the bottom and
band being fastened together by an angle iron h rivetted to such band to which
angle iron the bottom is fastened by screws and nuts i or their equivalents.
I would here observe, that I do not limit myself to the precise details of
construction hereinbefore described and shewn as the same admit of variation in
minor details without departing from the essential features of my invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what 1.
claim is:
1. As a new article of manufacture a hand sieve having a removable adjustable
bottom fitted in a band either perforated or plain all substantially as hereinbefore
described and shewn.
2. In a hand sieve securing the bottom to the band so as to allow of such bottom
being readily removed and replaced or renewed all substantially as hereinbefore
specified.
