PROVISIONAL SPECIFICATION.
Improved Water Filter.
BENJAMIN HARDWICK FOSTER 12 Gosforth Terrace, Gosforth Newcastle-upon-
Tyne County of Northumberland Engineer do hereby declare the nature of this
invention to be as follows:-
The two improvements I claim for in this Filter is that I have an Iron or
Steel Bolt which passes through the six perforated plates with the Carbon in
between, and as two Steel Plates one at the bottom and one at the top of the
perforated Plates, and the holes in the Steel Plates are large so that the water can
pass through to the perforated Plates and by the holt being screwed at the two ends
can compress the Carbon within the Cylinder of the Filter to any given pressure
to suit any class of dirty water also for clensing the Filter I claim the right of
clensing by steam instead of unfiltered water, I have a valve at the bottom of the
Filter on the side of the Cylinder which the unfiltered water enters and passes up
through the perforated plates and body of Carbon, and out at the valve at the top
of the Cylinder Pure for clensing the Filter, I have a steam valve fitted on the top
of the Cylinder and a valve at the very bottom of the Cylinder and by turning off
the inlet and outlet valves, open the valve at the bottom and turn on the steam valve
the carbon is thoroughly clensed and by this arrangement it keeps the chemical
power of the carbon pure takes off all the mud and impurities collected in the mud
chamber.

Improved Water Filter.
BENJAMIN HARDWICK FOSTER Engineer No. 12 Gosforth Terrace Gosforth
Newcastle-on-Tyne County of Northumberland England 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:-
I Benjamin Hardwick Foster of Newcastle-on-Tyne in the County of Northumber-
land do hereby declare the nature of the said invention for "Improvements in
Filters to be as follows
"
This invention consists of three improved methods of constructing and arranging
the parts of Filters used for the purpose of separating impurities from water or other
fluids by which improved methods the apparatus is more effective in its operation and
more easily cleansed than in Filters as ordinarily constructed and used.
The three improvements I claim for in this Filter is I have an iron or steel Bolt F
which passes through the six perforated plates H with the carbon in between and as
two steel plates one at the bottom and one at the top I, and the holes in the steel
Plates are large so that the water can pass through to the perforated plates H and by
the Bolt being screwed at the two ends, I can compress the Carbon within the
cylinder of the Filter to any given pressure to suite any class of dirty water, also for
clensing the Filter I claim the right of clensing by steam instead of with unfiltered
water, I have a valve G at the bottom of the Filter on the side of the cylinder A
which the unfiltered water enters and passes up through the perforated plates and
body of Carbon, C, and out at the valve at the top D of the cylinder pure, for clensing
the Filter I have a steam valve E fitted on the top of the cylinder and a valve G at
the very bottom of the cylinder and by turning off the inlet A and outlet valves D
U17

page_text: open the valve G at the bottom and turn on the steam valve E the Carbon is thourougly
clensed and by this arrangement it keeps the chemical power of the Carbon C pure,
takes off all the mud and impurities collected in the mud chamber B.
Having now described the nature and particulars of my said invention and the
manner in which the same is to be performed, I desire it to be understood that
I claim
First. The construction of Filters having steam for clensing the Carbon.
Second. The construction of a bolt and steel Plates for compressing and holding
the Carbon together within the cylinder.
Third. The large Mud Chamber for collecting the mud.
The above improvements are herein described and Illustrated in the accompanying
sheet of drawings.
