EDWIN JONES, Joiner, Clive Street, Tunstall, Staff. ALFRED BEECH, Potters
Manager, Swan Bank Pottery, Tunstall, Staff. do hereby declare the nature of this
invention to be as follows:-
Our invention refers to that class of filter press used by Potters and others for the
reduction of slip or any semi-fluid matter to a solid state.
These filter presses are usually constructed of wood, and consist of a number of
trays bound together by means of iron bands and screws. Each tray being composed
of a number of grooved planks which are held together by means of oak strips. The
present mode of charging said presses is by introducing a metal "nozzle" into the
interior of the press through apertures cut in the said oak strips. As the said oak
strips constitute the strength of the said trays, the cutting of them to admit said
nozzles considerably weakens them.
Hitherto the before named oak strips were recessed into the planks, thereby
blocking up the ends of the grooves, so that apertures have to be cut in the edges of
said planks to allow the liquid to escape. Said apertures are detrimental to the trays,
generally causing them to split open and become useless.
By means of our invention we overcome these difficulties.
In charging the presses we use a cranked "nozzle" which we introduce through
apertures cut out of the planks, said nozzles being connected to the main pipe in the
usual manner. In binding the planks together, we bevil the oak strips and the ends
of the planks, and at the bottom of each press continue the grooves to the end of the
planks to allow the liquid to freely escape. By obviating the necessity of cutting
apertures in the oak strips to admit the nozzles, and also the edges of the planks for
the escape of the water, a press constructed according to our invention would be
stronger, and consequently more durable.

Improvements in Filter Presses and the Mode of Charging same
EDWIN JONES, Joiner, Clive Street, Tunstall, Staff. ALFRED BEEOH, Potters
Manager, Swan Bank Pottery, Tunstall, Staff. do hereby declare the nature of our
invention for IMPROVEMENTS IN FILTER PRESSES AND THE MODE OF CHARGING SAME,
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
Our invention refers to that class of filter press used by. Potters and other for the
reduction of slip or any semi-fluid matter to a solid state. These filter presses are
usually constructed of wood and consist of a number of trays bound together by
means of iron bands and screws. Each tray being composed of a number of grooved
planks which are held together by means of oak strips. The present mode of charging
said presses is by introducing a metal nozzle into the interior of the press through
apertures cut in the said oak strips. As the said oak strips constitute the strength of
the said trays, the apertures required to be cut in them to admit the nozzles
considerably weakens them.
Hitherto the before named oak strips were recessed into the planks, thereby
blocking up the ends of the grooves, so that apertures have to be cut in the edges of
said planks to allow the liquid to escape.
Said apertures are detrimental to the trays, generally causing them to split open
and become useless.
By means of our invention we overcome these difficulties.
In charging the presses we use a cranked nozzle which we introduce through
apertures cut out of the planks, said nozzles being connected to the main pipe in the
usual way. In binding the planks together, we bevil the oak strips and the ends of
the planks, and at the bottom of each tray continue the grooves to the ends of the
planks to allow the liquid to freely escape. By obviating the necessity of cutting
apertures in the oak strips to admit the nozzles, and also the edges of the planks for
the escape of the water a press constructed according to our invention would be
stronger, and consequently more durable.
Reference may now be had to accompanying drawings, in which the same letters
refer to the corresponding parts in each figure.
Fig. 1 is an elevation of a tray with nozzle in position.
Fig. 2 is a plan.
Fig. 3 a section through centre of charging aperture.
Figs. 4 and 5 shew two views of nozzle drawn to a larger scale.
The mode of operating is as follow:-The cloth A is attach to cranked nozzle B in

page_text: the usual manner and secured by nut and washer C. We then insert the said cranked
nozzle B in the aperture F cut out of grooved plank to receive it, and provided with
slide plates G, G. to hold it in position, the top part of said nozzle being connected to
the stand or press pipe by means of a tap in the usual manner. Be it particularly
observed that the apertures F, cut out to admit the nozzles are in the centre of the
thickness of the trays, instead of at the edges, as heretofore.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we claim is :—
I. The cranked nozzle 6 for charging filter presses.
II. The mode of charging the presses, through apertures cut out of the centre of
the thickness of each tray as herein described and illustrated by accompanying
drawings.
