Improvements in Kitchener and like Stoves.
I, FRITZ HILTER, of 22 Edwardes Square, Kensington, in the County of London,
Manufacturer, 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 has for its object certain improvements in kitchener and like stoves
whereby the heat generated by the combustion of fuel may be better controlled and
utilised than has heretofore generally been possible.
For this purpose I provide such stoves with two passages or flues, beneath the
oven or ovens, these being arranged one below the other and communicating at one
end. At its opposite end the lower of these flues communicates with the chimney
through a three-way valve constructed essentially of a cylindrical casing having three
openings therein, and containing a sector plate capable of being so operated that it
may be arranged to close either of these openings. The first of these openings
communicates with the lower of the two flues, the second with the usual passage
round the oven, and the third with the chimney.
A stove embodying my improvements is illustrated in front sectional elevation and
end sectional elevation respectively by Figs. 1 and 2 of the accompanying drawings,
by the aid of which I will more clearly describe my invention and the manner in
which the same may be carried into practical effect.
As shown this stove has formed in its lower part beneath the oven a two passages
or flues arranged one below the other and communicating at one end with each
other through a passage c.
At the opposite ends of these passages or flues bb1 to those communicating with each
other, is arranged a three-way valve D formed of a cylindrical casing d, containing
a sector plate e capable of being operated by handle or equivalent means, so that
it may be brought to close any one of three openings formed in said casing d and
which communicates respectively with the lower passage b', the ordinary passage g at
the side of the oven a, and the chimney h.
With such an arrangement it will be seen that the resulting products of com-
bustion of a fire on the grate & after passing over the oven and down the passage g
may be either caused to flow directly to the chimney, or to any other point should
it be desired to utilize the heat for purposes other than heating the oven, or it may
be caused to pass through the passages 66, or in both directions, or may be caused
to pass through said passages bb' and then return to the fire. It will thus be seen
that not only can the draught be regulated as desired, but the heat better utilized
and a consequent saving of fuel effected. When desired the chimney / may be
arranged to pass downwards or into a second stove or in any other direction.
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 I
clain is :-
A kitchener or like stove with passages bb' and a three-way valve D arranged and
operating substantially as described and illustrated in the accompanying drawings.
