PROVEMENTS IN THE MANUFACTURE OF BOILERS FOR RANGES, STOVES, AND OTHER
SIMILAR PURPOSES."
This Invention has for its object improvements in the manufacture of boilers for
ranges, stoves, and other similar purposes.
Hitherto it has been customary to manufacture boilers for ordinary ranges,
stoves, and other similar purposes entirely of cast iron, the body of the boiler being
cast in one piece, and the top thereof in one or more pieces as required. It is well-
known that this method greatly increases the difficulties of expense and manu-
facture, owing to the fact that it necessitates a fresh pattern or mould, or patterns
or moulds being made for the body of the boiler, if any deviation whatever from
the size or sizes of existing patterns or moulds becomes requisite. Such patterns
or moulds are costly, and this disadvantage is particularly experienced when it
becomes necessary to replace the boiler in a range or stove which has been damaged
or injured by a new one owing to the patterns being very numerous, and thus
making it difficult and frequently impossible to find the right size. Now by my
Invention, I obviate these various disadvantages in the following manner :-I make
those parts of the boiler which come in immediate contact with the fire, either of
cast iron or of thick wrought iron or copper, or any other suitable metal, and I
make such parts thereof which do not come into such contact of light sheet iron, or
of any other suitable sheet metal which is capable of being easily shaped into any
required form and size.
By this improved method of manufacture, I dispense with the necessity of
making fresh patterns or moulds as those parts of the boilers which are cast may be
made of various sizes and shapes with a single pattern or mould, or a single set of
patterns or moulds, and when so made can be kept in stock ready for any exigency
that may occur, while the other portions of the boiler being made of sheet metal
can in every case be fitted with facility and at a greatly reduced expense.
In order to make the various joints in the boiler water tight, I galvanize the.
same after they are made, so that they are thoroughly and effectually closed.
Or if desired the boiler may be made entirely of sheet iron, copper, or other
suitable metal, and those parts thereof which would come in immediate contact
with the fire may, if desired, be protected by a plate or plates of cast or thick
wrought iron. It will however be found in practice that this method is not so

page_text: desirable as that already described,_as_boilers so manufactured entirely of thin
sheet metal would be deficient in durability, and would therefore require frequent
renewal, thereby causing both inconvenience and expense, and thus rendering the
composite method of manufacture first described preferable.
In this latter method, I also galvanize the various joints of the boiler in order to 5
make-them watertight.
