page_text: I, HENRY JOHN WORSSAM of Wenlock Road, City Road in the County of
Middlesex, Engineer do hereby declare the nature of this invention to be as
follows:-
Strainer-plates for hop-backs and mash-tuns for breweries have heretofore been
made of metal plates of considerable thickness, on account of the weight they
have to bear when a workman stands upon them when cleaning out the receptacle.
In consequence hereof the small holes or slits in them require to be considerably
enlarged or splayed on the underside, in order to prevent them from becoming
choked, and this necessitates the placing of the holes at a comparatively large
distance apart, whereby the straining action of the plate is greatly reduced. My
present invention has for its object to obviate this inconvenience and also to render
the plates lighter and more easily handled.
For this purpose I construct the plates of hard rolled yellow metal or copper,
whereby I am enabled to make them very thin, and as the holes or slits in this
case require no splaying on the underside, or only very slightly so, they can be
arranged quite close together. In order to afford such thin strainer-plates the
requisite strength, I provide beneath them a framing formed of deep narrow metal
bars arranged in any convenient manner so that while affording the requisite
strength, they offer but little obstruction to the straining surface; and to reduce
such obstruction to the smallest possible extent, I form the upper edge of the bars
either rounded or bevilled, or with notches or serrations.

Middlesex, Engineer, 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:-

Fig. 1 of the accompanying drawings is a longitudinal section, Fig. 2 is a
transverse section and Fig. 3 is a plan of a strainer plate and its frame according
to my invention.
A is the thin metal plate perforated with numerous holes or slits
and supported on the ribs B of a framing, these ribs preferably having their upper
edges rounded so as to offer little obstruction to the holes of the plate immediately
above them.
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
I claim is
Constructing a strainer for a hop-back. or mash-tun of a thin perforated plate
supported on a framing substantially as and for the purpose herein set forth.
