PROVISIONAL SPECIFICATION.
Improved Fuel Economiser and Water Heater for Steam Boilers
and Heating Water for Warming Rooms of every Description.
JOSEPH PIMBLEY Engineer Albert Villas 684 Manchester Road Great Lever
Moses Gate do hereby declare the nature of this invention to be as follows:-
My invention consists of a number of pipes similar to other fuel economisers.
The pipes are about four feet long and fitted with scrapers worked by lever
motion from shaft revolving from end of economisers. In my improvement the
scrapers are worked from a rotary motion, dispensing with the ordinary jack
motion. The pipes are so arranged as to have forced circulation through each
pipe and the easy arrangement for cleaning same of any scurn or dirt from the pipes
after working. In the centre of machine is fixed a large tube or cylinder with a
number of internal pipes so that they can use the exhaust steam or any waste steam
about the boilers or any other part of the works. The tube or cylinder is so
arranged that same can be worked with or without pipes for heating water for
warming rooms of every description. The tube or cylinder in the centre of
economisers is fitted with revolving scraper so as to keep any soot from adhering
to the surface of the casing. When used for warming rooms the tube or cylinder
will be fitted with scraper inside of tube as well as outside and worked by an
ordinary rotary motion. The economiser consists of a number of pipes cast with
partitions through the centre thus dividing the actual pipe into two pipes. 'A
number of these pipes are bolted to a long cast iron top box. This box has a
number of thoroughfares communicating with the vertical pipes. My mode of
forcing circulation is by the water entering at the top of the economiser and through
the top box going down the first half of the pipe and up the other half and so down
and up through all the pipes until the water enters the boiler.

JOSEPH PIMBLEY Engineer Albert Villas 684, Manchester Road Great Lever
Moses Gate, 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 :-
My invention consists of a number of pipes A of special construction about four
feet long cast with a partition through the centre B thus dividing the actual pipe
into two pipes. The pipes A are bolted to a long cast iron top box C. The box C
is arranged with thoroughfares D for circulating the water through each pipe A.
The water enters the economiser at the top box and flows down the first half of the
first pipe and up the other half of the first pipe and then through the thoroughfare D
in the top box C to the first half of the second pipe A. and so on to the end of the

page_text: pipes A down and up through every pipe A until the water reaches the feed pipe E
for the boiler. The top box C is prepared with a bonnet fover each pipe A to
facilitate cleaning the pipes A. The pipes A are also fitted with a bonnet G at the
bottom end. The pipes A are fitted with scrapers H worked by a lever motion I from
shaft J revolving from end of economisers. The scrapers H are worked from a rotary
motion K dispensing with the ordinary jack motion. In the centre of machine is
fixed a tube L or cylinder L that can be used either with or without the economiser.
The cylinder L is fitted with a number of internal pipes M through which the
waste steam from the boiler or any other part of the works can be circulated.
The object of the tube L or cylinder is for heating water for warming rooms of
every description. The tube L or cylinder is fitted with a revolving scraper N so
as to keep any soot from adhering to the surface of the casing. When used for
warming rooms of every description the tube L or cylinder will be fitted with
scraper inside as well as outside of tube L or cylinder. The scrapers N will be
worked by an ordinary rotary motion O.
When not used for warming rooms the tube L will form part of the economiser.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what 1
claim is :-
•
1. The top box C so constructed as to form a chamber D or thoroughfare over
the second half of the first pipe A and the first half of the second pipe A and so
on to the end of pipes substantially as herein described and as illustrated by the
accompanying drawing.
2. Suspending the water pipes which form the economiser from the top of the
flue whereby I gain the greatest amount of heat possible.
3. A bonnet on the top box over each pipe A and a bonnet G at the bottom of
each pipe A by this means each pipe A can be thoroughly examined and cleaned.
4. Working the scrapers H direct from the beam R thereby dispensing with any
chains or loose catches said beam being worked by an ordinary rotary motion K
with connecting rod P coupled to lever I and face plate crank K which arrangement
dispenses entirely with the ordinary reversing motion.
5. The section of pipe A whereby I obtain a much greater heating surface than
is obtained with any other section of pipe hitherto used in economisers.
