Steam Boilers.
JOSEPH JOHN HANCOCK, Builder No. 2 Island Cottage, Old Church Road
Clevedon Somerset do hereby declare the nature of this invention to be as
follows:-
The improved tanks or chambers for supplying composition to clean and preserve
steam boilers are for directing, measuring and regulating the quantity and times of
using the composition.
The tanks are to be made for suction feed pipe or boiler.
Each tank or chamber to have the directions cast, securely attached or otherwise
supplied.
The tanks or chambers to be of the following dimensions-1 pint for each
10 horse power boiler-1 quart for each 20 H.P. boiler-3 pints for each 30 H.P.
boiler gallon for each 40 H.P. boiler-5 pints for each 50 H.P. boiler-6 pints
for each 60 H.P. boiler and other sizes pro ruta.
The directions to each tank to be
Half gallon to fill once weekly for day work, twice weekly for day and night
work for each 40 horse power boiler-nominal-sludge daily.
One pint to fill once weekly for day work twice weekly for day & night work for
each 10 horse power boiler-nominal-sludge daily.
Similar directions to all other sizes.
Marine boilers and others with condensers.
The tanks and chambers to be of the following dimensions gallon for each
40 H.P. boiler-nominal-6 pints for each 60 horse power boiler-nominal-other
sizes pro rata.
To fill once for each 6 days working or 3 days and nights working.
Scum before filling-not after.
The tanks are to be used as follows
At the periods mentioned in the directions while the pump or injector is working—
Lift the cover of suction feed pipe tank-put in the composition then close the cover
and open the tap, when the tank is empty close the tap.
The pressure tanks & chambers to feed pipes & boilers are to be used as follows
Shut the feed tap into boiler open the drain & filling taps, when empty close the
drain tap and fill the chamber with composition, then shut the filling and open the
feed tap.
The pressure chamber into steam space to be used as follows-

JOSEPH JOHN HANCOCK 2 Island Cottage Old Church Road Clevedon Somerset
Mason & Builder 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 :-
The improved tanks or chambers for supplying composition to clean and preserve 5
steam boilers are for directing measuring and regulating the quantity and times of
using the composition.
The tanks are to be made for the suction feed pipe S. P. 1 & 3 or steam space P.
Fig. 1 and for the pressure feed pipe or water space of boiler W Fig. 2.
Each tank or chamber to have the directions A cast, engraved, securely attached 1
or otherwise supplied.
The tanks and chambere to be of the followinơ dimensions.
The tanks and chambers to he of the following dimensions.

The directions to each tank to be
Half gallon to fill once weekly for day work-twice weekly for day and night
work for each 40 horse power boiler-nominal-sludge daily.
Similar directions to all other sizes.
Marine boilers and others with condensing engines.
The tanks and chambers to be of the following dimensions:
Half gallon for each 40 horse-power nominal six pints to each 60 horse power
boiler nominal.
Other sizes pro rata.
To fill once for each six days working or 3 days & nights working.
Scum before filling not after.
For locomotive boilers with 2-18 in. cylinders.
One pint fill four times weekly for day work.
Other sizes pro rata.
For portable and traction engine boilers pint fill twice weekly for day work for
each ten horse power boiler nominal.
Other sizes pro rata.
The tanks No. 1. 2. & 3 see drawings are to be used as follows-
At the times or periods mentioned in the directions.
Tank Fig. 3 to suction feed pipe S while the pump or injector is working open
the top A and put in the composition then close the cover A and open the tap C
when the tank is emptied close the tap C.
The pressure tank or chamber No. 2 to feed pipe or water space of boilers is to
be used as follows-
Shut the tap D into boiler or feed pipe Fig. 2 open the drain tap E and filling
tap or plug F. When the tank or chamber is emptied of water close the drain tap Ĕ
and fill the tank or chamber No. 2 with composition then shut the filling tap or
plug F and open the supply tap D into the water space or feed pipe W.
The pressure tank or chamber Fig. 1 into steam space P. to be used as follows
Shut the feed tap C into steam space P Fig. 1 and open the filling tap or plug B
