I, HENRY JOHN ROGERS Engineer Lavington House Watford Herts do hereby
declare the nature of this invention to be as follows:-
This Invention relates more particularly to the renovating of Strainer plates used by
paper makers and others and consists in forming a recess all round the inside of the
margin of the worn plate by means of a rotary cutter or drill to the exact depth of the
main body of the plate thus removing the whole of the slits and grooves and leaving
nothing but the margin and strengthening ribs; I then insert in the space thus left
vacant an entirely new strainer plate of hard rolled brass or other metal which I rivet
or otherwise firmly affix to the margin in the recess formed by the cutter or drill and
to the strengthening ribs aforesaid; by this means I construct a plate possessing a
surface of hard and tough metal and at the same time prevent the parting of the
surface from the foundation plate which occasionally occurs when the said surface is
soldered as is now the practise and I form a very much stronger and more durable
plate which can be renewed any number of times without destroying the original
framework thereof.
Or the interior of the margin may be dovetailed or grooved and the new plate
pressed or forced therein by hydraulic or other pressure.
Dated this 20th day of September 1886.

I HENRY JOHN ROGERS of Lavington House Watford in the county of Hertford
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 :-
This Invention relates to the renovating of strainer plates used by paper makers and
others and consists in forming a recess all round the inside of the margin A of the
worn plate or on two or more sides thereof by means of a rotary cutter or drill to the
exact depth of the main body of the plate thus removing the whole of the slits band
grooves c and leaving nothing but the margin A or part of the margin and strengthening
ribs B.
I then insert in the space thus left vacant an entirely new strainer plate of hard
rolled brass or other metal which I rivet or otherwise firmly affix to the margin in the
recess formed by the cutter or drill and to the strengthening ribs B aforesaid; by this
means I construct a plate possessing a surface of hard and tough metal and at the same
time prevent the parting of the surface from the foundation plate which frequently
occurs when the said surface is soldered, as is now the practise and I form a very
much stronger and more durable plate which can be renewed any number of times
without destroying the original framework thereof. Or the interior of the margin
may be dovetailed or grooved and the new plate pressed or forced therein by hydraulic
or other pressure. In the Drawings Fig. 1 and 2 are full sized sections shewing the
new plate inserted in the space cut out as aforesaid and rivetted to the old margin and
ribs Figs. 3 and 4 are reduced plan and section of a whole plate shewing the process
applied in a similar manner.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I would have it understood that I am
aware that Patents have been granted to George Tidcombe Junr. Nos. 106681 and
482283 and I desire to state that I do not claim attaching a new surface to strainer
plates by rivets or otherwise or attaching a hard or tough metal surface to such plates
unless such surface is made with cells c as well as slits but what I do claim is :-
The renovating old worn strainer plates by cutting out or otherwise removing the
slits and grooves leaving only the margins and ribs, and fixing and fitting in the space
thus left vacant an entirely new strainer plate of hard metal of greater durability than
the cast metal removed, substantially as hereinbefore described and illustrated.
Dated this 17th day of January 1887.

Strainer Plates Used by Paper Makers and others.
I HENRY JOHN. ROGERS of Lavington House Watford in the county of Hertford
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 :-
This Invention relates more particularly to the renovating of strainer plates used by
paper makers and others and consists in forming a recess all round the inside of the
margin A of the worn plate or on two or more sides thereof by means of a rotary
cutter or drill to the exact depth of the main body of the plate thus removing the
whole of the slits b and grooves c and leaving nothing but the margin A or part of the
margin and strengthening ribs B.
I then insert in the space thus left vacant an entirely new strainer plate of hard
rolled brass or other metal which I rivet or otherwise firmly affix to the margin in the
recess formed by the cutter or drill and to the strengthening ribs B aforesaid; by this
means I construct a plate possessing a surface of hard and tough metal and at the same
time prevent the parting of the surface from the foundation plate which frequently
occurs when the said surface is soldered, as is now the practise and I form a very
much stronger and more durable plate which can be renewed any number of times
without destroying the original framework thereof. Or the interior of the margin
may be dovetailed or grooved and the new plate pressed or forced therein by hydraulic
or other pressure. In the Drawings Fig. 1 and 2 are full sized sections shewing the
new plate inserted in the space cut out as aforesaid and rivetted to the old margin and
ribs; Figs. 3 and 4 are reduced plan and section of a whole plate shewing the process
applied in a similar manner, and it is evident that this process may be applied to the
manufacture of new Strainer Plates as well as to the renovating of old plates.
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 :-
1° The renovating old worn strainer plates by cutting out or otherwise removing the
slits and grooves leaving only the margins and ribs, and fixing and fitting in the space
thus left vacant an entirely new strainer plate of hard metal of greater durability than
the cast metal removed.
2° The manufacture of new strainer plates by the insertion of hard rolled metal
plates, composed of the slits and grooves as before described, into cast margins
and ribs.
