IMPROVEMENTS IN SUCTION PIPES FOR PUMPS
Year: 1886

page_text: I, ALFRED TOZER of the Chief Fire Station Jacksons Row Manchester,
Superintendant of the Manchester Fire Brigade do hereby declare the nature
of my invention for IMPROVEMENTS IN SUCTION PIPES FOR PUMPS to be as
follows:-
This invention relates to the construction of an improved form of strainer for
attachment to suction pipes. One method of construction according to my
invention, is as follows-
A box of copper or other suitable metal of oblong form, is constructed, having
top and bottom plates of sufficient size to overhang the sides. The sides are
perforated with numerous holes of suitable diameter.
Between the overhanging portions of the top and bottom plates, rods or wires
are secured, which protect the sides of the strainer from damage and also prevent
leaves and other substances from closing the holes in the sides.
On the top of the upper plate, near one end, a female screw is secured for the
attachment of the suction pipe. In some cases a short Hexible connection of
leather or other suitable material is interposed between the female screw, and the
top of the strainer, in order that the strainer box may keep level while the angle
of the suction pipe is allowed some variation.
The arrangement above described is specially adapted for use with fire engines,
when the strainer is placed in a canvas cistern, or other shallow reservoir.
In some cases the strainer is circular in form, instead of being oblong as before-
described.
The construction of the wire guard may also be modified by bending the ends
of the wires and attaching to the top and bottom of strainer in which case the
top and bottom plates would not overhang.

page_text: I ALFRED TOZER of Jackson's Row Fire Brigade Station Manchester in the
County of Lancashire, Superintendent of Fire Brigade 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 an improved form of strainer for attachment to suction
pipes.
The strainer may be made in any convenient form, those in the drawing
however being found the most useful.
A box of copper or other suitable metal is constructed the sides being perforated
as for an ordinary strainer. The top and bottom plates are made to overlap the
sides and wires or rods B in figs. 2 & 3-or wire netting as in fig. 1 are placed
as shown for the purpose of protecting the strainer from injury, also to prevent the
holes being clogged with leaves, straw, &c.
In figs. 2 the wires B, are shown curved, this form offering greater resistance to
injury.
On the top of the upper plate a short pipe C is fixed, preferably at an angle of
about 60°, and carrying a screw D or other attachment for suction hose.
In some cases the pipe C is flexible and formed of leather, or other suitable
material, in order that the strainer box may remain level while the suction pipe is
allowed a certain amount of vertical play.
The arrangement above described is specially adapted for use with fire engines,
when the strainer is placed in a canvas cistern or other shallow reservoir.
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 combination of wires rods or netting placed around the strainer for the
purpose of protecting the perforated plate and preventing the holes being clogged.
2. The combination with a strainer of a pipe placed at an angle as described,
either flexible or rigid, for the purpose of allowing the strainer to lie level, while
the direction of the suction pipe forms an angle with the ground line.
