PROVISIONAL SPECIFICATION.
Improvements in Filters.
I JOSIAH HAMPTON, 64 Regent Street, Loughborough, Leicestershire,
Engineer, do hereby declare the nature of this invention to be as follows:-
Each filter consists of an outer vertical cylinder closed at the bottom by a plate
inclined downwards from its rim to the centre which is perforated.
Beneath the perforation a pipe provided with a stop cock or valve is secured.
The bottom of the cylinder rests on a metal stand at a suitable height from the
floor. The top of the cylinder is closed by a lid bolted to it, provided with two
orifices one near the edge and the other at the centre, the one near the edge is
connected to an inlet pipe provided with a stop cock or valve. The centre orifice
is provided with a delivery pipe above it, and a perforated double flanged connecting
piece below it. The outer cylinder contains an inner one somewhat shorter and of
less diameter than the outer one. The inner cylinder a short distance from the
bottom is provided with a vertically perforated flanged plate. The space between
the flanged plate and the inclined bottom of the outer cylinder forms a sediment
chamber.
The top of the inner cylinder is closed by a lid provided on its underside with a
shallow chamber having a perforated bottom, the lid has an orifice at the centre
and is bolted to the lower flange of the connecting piece before named.
The inner cylinder above the perforated plate near the bottom is charged with
several layers of charcoal up to within a few inches of the bottom of the perforated
chamber, the layers of charcoal are separated by two or more perforated plates of
the same diameter as the interior of the cylinder.
Upon the cock or valve of the inlet pipe being opened the water to be filtered
enters the outer cylinder, surrounds the inner cylinder, fills the sediment chamber,
and passes through the perforated plate near the bottom, up through the layers of
charcoal and through the perforations in the bottom of the shallow chamber and
out through the delivery pipe to where required.
The inlet and delivery pipes of the outer cylinder may be connected by a short
pipe provided with a stop cock or valve, kept closed when the filter is in use, and
the delivery pipe may be connected to a boiler if required.
To cleanse the filter the inlet pipe to the outer cylinder is closed, the stop cock
or valve at the bottom is opened and upon the stop cock or valve of the short pipe
connecting the inlet and delivery pipes being opened water will rush downwards
through the charcoal in the inner cylinder, through the sediment chamber, and out
through the pipe at the bottom.
Or if the delivery pipe is connected to a boiler, steam or hot water may be
allowed to take the same course to cleanse the filter.

Improvements in Filters.
I, JOSIAH HAMPTON, 64 Regent Street, Loughborough, Leicestershire,
Engineer, 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 :-

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a plan of an improved filter with the inlet and delivery pipes
separate.
Figure 2 a vertical sectional view of a filter with the inlet and delivery pipes
connected.
Figure 3 a sectional view on the lines A, A, of Figure 2.
Each filter consists of an outer vertical cylinder 1 shown at Figure 2 closed at
the bottom by a plate 2 inclined downwards from its rim to the centre which is
perforated.
Beneath the perforation a pipe provided with a stop cock or valve 3 is secured.
The bottom of the cylinder rests on a metal stand 4 at a suitable height from the
.floor.
1
The top of the cylinder is closed by a lid 5 bolted to it, provided with two
orifices one near the edge and the other at the centre, the one. near the edge
is connected to an inlet pipe provided with a stop cock or valve 6. The central
orifice is provided with a delivery pipe 7 above it, and a stop cock 8. Below the
lid is a perforated double flanged connecting piece 9. The outer cylinder contains
an inner one 10 somewhat shorter and of less diameter than the outer one.
The inner cylinder a short distance from the bottom is provided with a vertically
perforated flanged plate 11, the space between the plate and the inclined bottom of
the outer cylinder forms a sediment chamber. The top of the cylinder 10 is
closed by a lid provided on its underside with a shallow chamber 11 having a
perforated bottom, the lid has an orifice at the centre and is bolted to the lower
Hange of the connecting piece 9.
The inner cylinder above the perforated plate 11 is charged with layers of
charcoal 12 up to within a few inches of the bottom of the chamber 11, the
layers of charcoal are separated by two or more perforated plates 12ª of the same
diameter as the interior of the cylinder.
The inlet and delivery pipes of the outer cylinder may be either separate as
shown at Figure 1, or they may be connected as shown at Figure 2 by a pipe
provided with a stop cock or valve 13, kept closed when the filter is in use.
the delivery pipe may be connected to a boiler if required.
And
Upon the cock or valve of the inlet pipe being opened the water to be filtered
enters the outer cylinder, surrounds the inner cylinder, fills the sediment chamber,
and passes through the perforated plate near the bottom, up through the layers of
'charcoal, through the perforations in the bottom of the shallow chamber, and out
through the delivery pipe to where required.
To cleanse the filter the inlet pipe to the outer cylinder is closed, the stop cock
or valve at the bottom is opened, and upon the stop cock or valve of the pipe con-
necting the inlet and delivery pipes being opened water will rush downwards through
the charcoal in the inner cylinder, through the sediment chamber and out through
the pipe at the bottom.

.
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 :
The construction and employment of the parts numbered 1 to 13 combined
to form a filter, substantially as described and illustrated in the drawings annexed.
