PROVISIONAL SPECIFICATION.
An Improved Apparatus or Device for Removing Solid Impurities
from Water or other Liquids, or for Preventing the Passage of
such Impurities therewith.
I EDWARD HENRY RIDDELL of 50 Queen Anne's Gate in the City of
Westminster Engineer do hereby declare the nature of this invention to be as
follows:-
My invention has for its object .to provide a simple apparatus or device which
will remove solid impurities from water or other liquids and which can be readily.
cleaned. It is capable of use in any situation where it is desired to retain sand or
other solid impurities or to prevent its passage with the water or other liquid, for
example in drawing water from rivers or other places where such impurities are
liable to be drawn in with the water. According to my invention I provide the
termination of the pipe or passage through which the water or other liquid passe
with a perforated end which encloses pieces or particles of matter preferably iron,
or other solid globules, the said perforated end. consisting preferably of a partly
spherical end piece with perforations therein the inner edges of the perforations
being grooved or corrugated so that when the globules or the like rest thereon
they do not entirely close the said perforations. The said partially spherical en 1
piece is secured to an attachment to the end of the pipe or passage which securing
may be effected by screwing one part upon the other this also affording a means of
securing in place a grid which is situated between the said pipe or passage and the
partly spherical end piece so that the globules or the like contained in the said end
piece are retained in the said end piece. When water or other liquid is drawn or
forced through the end piece the globules or the like prevent the passage of sand
or other solid impurities and by the passage of water or liquid in the reverse
direction the sand or other solid impurities can be ejected and the apparatus thus
readily cleaned.

COMPLETE SPECIFICATION.
An Improved Apparatus or Device for Removing Solid Impurities
from Water or other Liquids, or for Preventing the Passage of
such Impurities therewith.
EDWARD HENRY RIDDELL of 50 Queen Ann's Gate in the City of
Westminster Engineer do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
My invention has for its object to provide a simple apparatus or device which
will remove solid impurities from water or other liquids and which can be readily
cleaned. It is capable of use in any situation where it is desired to retain sand or
other solid substances or to prevent its passage with the water or other liquid for
example in drawing water from rivers or other places where such impurities are
liable to be drawn in with the water.
According to my invention I provide the termination of the pipe or passage
through which the water or other liquid passes with a perforated end such as is
.

page_text: shewn in elevation in Figure 1 in vertical section in Figure 2 and in plan looking
from below, in Figure 3 of the accompanying drawings. The said perforated end
encloses- pieces or particles of matter preferably iron or other solid globules as
shewn at a the said perforated end consisting preferably of a partly spherical end
piece B with perforations therein, the inner edges of the perforations or of some
of them being grooved or corrugated as at so that when the globules a or the
like rest thereagainst they do not entirely close the said perforations. The said
partially spherical end piece B is secured to an attachment to the end of the pipe
or passage which securing may be effected by screwing one part upon the other by
means of the screw c on the partly spherical end piece B with which engages a
screw in the part D to which the pipe or the like is attached this also affording a
means of securing in place a grid E which is situated between the said pipe or
passage and the partly spherical end piece so that the globules or the like con-
tained in the said end piece are retained in the said end piece. When water or
other liquid is drawn through the end piece the globules or the like prevent the
passage of sand or other solid matter or impurities and by the passage of water or
liquid in the reverse direction the sand or other solid matter or impurities can be
ejected and the apparatus this readily cleaned.
The apparatus or device will prevent the escape of sand or other filtering
material when used in filters and when used for washing filters will enable the
operation to be effected with a minimum of resistance or friction. It constitutes
practically a new strainer after each operation of washing the filter bed.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. An apparatus or device for the purposes described the said apparatus being
constructed or arranged substantially as hereinbefore described and illustrated by
the accompanying drawings.
2. An apparatus consisting of a perforated end piece in which are contained and
retained globules or pieces or particles of matter substantially as and for the
purpose herein before described.
