I EDWARD WHITE ASTLE of 41 Litchurch St. Derby in the County of Derby
Millwright and Engineer do hereby declare the nature of my Invention for
IMPROVEMENTS IN THE CONSTRUCTION OF BOILERS FOR HEATING CHURCHES,
SCHOOLS, HOUSES, CONSERVATORIES & BUILDINGS OF EVERY DESCRIPTION, AND
FOR BATHS AND HOT-WATER SUPPLIES GENERALLY, to be as follows:-
The Boiler is a rectangular parallelogram in form and section of a fixed height
and width, and of any length according to requirements. It is constructed in
sections which may either be rivetted or bolted together—in the latter case copper
rings are inserted in joints.
It may be constructed with one or more flues, and by means of an aperture in
top of Fire-box over which the smoke from flue or flues must pass in its egress, a
great amount is consumed before the chimney is reached.
The firebox is of same section as boiler but smaller so as to allow water space at
top and sides but not at bottom.
Dampers are attached to the flues and are so constructed as to form cleansers
also-In passing along the flue they close the exit,
The whole of sides ends & top of fire box are Heating surfaces, with exception of
opening for fuel-The flue or flues also passing through the water no available heat
is wasted.
The Boiler is self containing-requires no setting-and may be fixed above or
below ground level.

I EDWARD WHITE ASTLE of 41, Litchurch St Derby in the County of Derby
Millwright and Engineer, do hereby declare the nature of my invention for
IMPROVEMENTS IN THE CONSTRUCTION OF BOILERS FOR HEATING PURPOSES &C
as aforesaid and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The Drawings submitted herewith show the form and construction of the Boiler,
in shape it is a rectangular parallelogram and can be made of wrought or Cast
Iron Copper or any suitable metal. The chief novelties in its construction are that
it is made in sections, and may be either Riveted or Bolted, except in the Angle
Iron round the bottom of the Fire Box which in all cases is riveted. When the
Boiler is put together with Bolts instead of Rivets two copper rings are inserted
between the Flanges for joints. The Boiler is so constructed as to admit of the
water surrounding the Fire Box on all sides, and also below the level of the firebars,
The Boiler can be made with one or more Flues, and by means of an aperture in the
top of the firebox over which the smoke must pass in its egress a great amount is
consumed before the chimney is reached, and the Flue or Flues pass through the
water from back of firebox to front of the boiler before entering the chimney thus
utilising all available Heat, They are fitted with Dampers so constructed as to act
as Cleansers for the said flue or flues, and the Boiler can by the removal of its
cover, which is always bolted, have its interior inspected and cleansed.
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
chain is
CIELI I8
1. The shape of the Boiler.
2. Its being constructed in sections.
3. Its adaptability for either Riveting or Bolting.
4. The cover being easily removed for inspection or cleansing.
5. The position of the Flue or flues, and their being arranged for partial
consuming of smoke.
6. The availableness of Dampers for cleaning the Flues as shown in Drawing No 2,
section C. D. Fig. 1 shews by dotted lines the damper closed, and Fig. 2. how the
damper by being pushed back cleans out the flues, the soot falls into the fire and is
consumed.
•
7. The Boiler is self-contained and requires no setting and may be fixed either
above or below the ground line.
