Improvements in or appertaining to Liquid Strainers.
I, JAMES MCEWEN, of 11 Rushton Street, Hulme, Manchester, in the County of
Lancaster, Aerated Water Engineer, do hereby declare the nature of my said
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 improvements in or appertaining to liquid strainers
wherein a sponge or other elastic or porous material is employed and consists in
ready and efficient means for regulating the speed of filtration, and for changing
or removing the sponge or other elastic or porous material to cleanse the same of
sediment or other impurities.
Fig. 1 is a sectional elevation of my improved strainer--Fig. 2 is an outside
elevation of same-Fig. 3 is a sectional plan through line A¹ B, and Fig. 4 is a
sectional plan through line C₁ D'.
A is the case or body of the strainer with the screwed end or nozzle B to allow of
its attachment to any kind of valve, tap, or pipe, supplying the water or other liquid
to be filtered or strained. In the upper end of the case or body A is fixed-by
soldering or other means-the perforated plate C. The outside of the case or body A
is provided with the lugs or projections D to receive the clips E carrying the cross-
bar F; the latter being secured by the nuts G. In the crossbar F is mounted the
screwed spindle H fitted with the operating handle 1. On the upper end of the
screwed spindle H is loosely seated the perforated plate K, which can be raised or pushed
into the case or body A by turning the screwed spindle H with the handle I.
Between the upper side of the perforated plate K and the under side of the perforated
plate C is charged or supplied with sponge or other elastic or porous material for the
purpose of filtering or straining water or other liquid supplied through the nozzle B.
To retard or prolong the operation of filtering or straining water or other liquids the
sponge or other elastic or porous material L is compressed by sliding the perforated
plate K towards the perforated plate C by means of the screwed spindle H, and
vice-versa to accelerate the operation.
An important feature of this invention consists in the ready means I adopt for
removing the sponge or other elastic or porous material L to cleanse the same of
sediment and other impurities. This is effected by simply releasing the pressure of
the perforated plate K from the sponge or other elastic or porous material L by means
of the screw H, the latter being operated so as to allow of the jaws M of the clips E
being lifted above the top side of the lugs or projections D, when, owing to the
clips E being on alternate sides of the lugs or projections D, the clips E can be
swivelled clear of the latter, after which the clips E, crossbar F, screwed spindle H,
and handle I can be removed bodily, thus allowing of the perforated plate K and the
ponge or other elastic or porous material L being removed, after which the latter
an be washed or cleansed of deposit and other impurities and then replaced, or
ubstituted by fresh material if desired, being secured in the contrary direction to
hat described for releasing it.
Having thus stated the nature of my invention and described the mode of perform-
ng the same, I would have it understood that I lay no claim to the use of sponge or
ther elastic or porous material as I am aware that such have been employed in con-
ection with filtering apparatus, but what I claim and desire to be secured to me by
etters Patent is :-
-
1. Regulation the

medium, substantially as described.
2. In liquid strainers the use of the lugs or projections D, clips E, crossbar F,
screwed spindle H, handle I, and plate K, for regulating the speed of filtering or
straining water and other liquids by compressing the sponge or other elastic or porous
material employed as a filtering medium, and for facilitating the removal of the
latter to cleanse the same of sediment and other impurities, substantially as described.
3. The combination, construction, and arrangement of parts forming my improved
liquid strainer, substantially as described and as shown on the drawings.
