WILLIAM WALSH, of 4, Burwell Road, Nottingham, Plumber, do hereby declare
the nature of this invention to be as follows:
This invention has reference to improvements in and relating to strainers
applicable to the end of pump suction pipes, the inlet end of siphons, and to
other similar appliances; the said invention being particularly suitable for use in
connection with means for emptying through a small opening, vessels containing
liquids which have a sedimentary deposit, such as the emptying of a beer barrel
through the bung hole.
The object of this invention is the provision of means by which the liquid is
the vessel to be emptied can be withdrawn without the sediment being disturbed
by the action of the instrument used, means by which the liquid can be with-
drawn to practically the level of the sediment, and means whereby an entensive
straining area is provided.
According to this invention the end of the inlet pipe is attached to a cup the
diameter or size of which is limited only by the opening through which it has to
be passed into the liquid. The inlet pipe and cup are so arranged that the end
of the pipe is below the upper edge of the cup, and to this latter there is attached
a vertical strainer which encircles the pipe, may be fastened thereto, and may be
of a length equal to the depth of the vessel to be emptied.

Improvements in and relating to Strainers applicable to Pumps,
Siphons, and similar Appliances.
WILLIAM WALSH, of 4, Burwell Road, Nottingham, Plumber, 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 has reference to improvements in and relating to strainers
applicable to the ends of pump suction pipes, the inlet ends of siphon pipes,
and to similar appliances, the improved strainer being particularly suitable for
use in connection with beer and other liquids containing a sedimentary deposit,
especially when such liquids have to be emptied through a bung or other small
hole in the vessel containing them.

page_text: The object of this invention is the provision of means by which the liquid in
the vessel to be emptied can be withdrawn from such vessel, either, without the
sediment being disturbed by the action of the instrument used or the outflowing
liquid, or, with a minimum of such disturbance, means by which the liquid can
be withdrawn to, practically, the level of the sediment, and means whereby an
extensive straining area is provided.
According to this invention the inlet end of the pipe used is attached to a cup
and provided with openings which are below the upper edge of the cup, and to the
outer circumference of the latter there is attached a straining surface which is
suitably supported at its upper end.
In the accompanying drawing which illustrates one method of carrying out
this invention the pipe a which may be part of a siphon or be connected to a pump
or other similar instrument is screwed or otherwise connected to a cup band is
provided with a convenient arrangement of inlet holes c the upper edges of which
are below the upper edge of the cup. Fitting the outside of the cup there is a
ring d to which a cylinder of fine metal gauze e is attached and is connected at its
upper end to a disc f which is made with a central hole to fit the pipe and may be
fastened thereto.
In the arrangement shown the parts may be separated for cleaning, the strainer
may be any length, while the height of the cup is partially governed by the depth
of the sediment and its diameter by the size of the hole through which it has to
be passed. The gauze cylinder may be stiffened by means of a perforated metal
cylinder, or by being wrapped round a wire frame.
With a strainer as herein described the liquid in the vessel to be emptied will
flow into the cup until it is level with the top of the cup, and the agitating effect of
the inflowing liquid upon the sediment is removed or greatly diminished, such
effect varying with the diameter of the cup.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, declare that what
I claim is:
-
A strainer constructed and arranged substantially as herein described with
reference to the accompanying drawings and for the purposes herein set forth.
