improvements in stoves with ovens for heating tailor's irons
Year: 1887

page_text: I, JOHN CROFT of 11 South Bruton Mews Bond Street London W. Whitesmith 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 relates to improvements in stoves with ovens for heating tailor's
irons.
Hitherto tailor's stoves have generally consisted of a metal oven with furnace set in
brickwork. This arrangement has several drawbacks. The flues are generally of
large area which makes it difficult to heat the oven uniformly and causes considerable
expenditure of time and fuel to get the irons properly heated. The usual brick
setting of these ovens allows no room for their expansion so that they frequently
crack at the first heating from this cause.
The object of my invention is to overcome these difficulties and to provide a self-
contained stove requiring no brickwork in which the irons can be quickly and
economically heated.
In carrying out my invention I provide a stove preferably constructed of cast metal
with a furnace underneath an oven. The products of combustion pass from the
furnace underneath the bottom of oven and up the sides in a series of flues instead
of one large one. This subdivision of the flue improves the draught and causes the
gases to come into contact with a larger surface of the oven than would otherwise be
the case thus more uniformly heating it. The gases pass from the sides over the
top of oven and from thence to the outlet. Baffle plates are provided to prevent the
gases making a direct course to the outlet so that the whole top of the oven may be
more uniformly heated.
The furnace may be constructed to burn coke or other fuel and is preferably
provided with loose firebars to facilitate renewal.
The oven is preferably formed with sides back and top in one piece resting on
bearings round the bottom and having a clear space outside at front or back sides and
top large enough to allow sufficient room for expansion in all directions. The bottom
of oven forms a separate piece slid into position from the front so as to admit of
easy renewal at any time without taking the stove to pieces.

page_text: The oven door opens outwards and is hinged at the bottom. Suitable stops are
provided to limit the opening of the door so that when open as far as stops will allow
it lies in the same plane as the bottom of oven thus forming a shelf upon which the
irons can temporarily rest during the operations of placing them in or withdrawing
them from the oven.
In some cases I provide air casings outside any or all of the flues through which the
air can circulate and keep them somewhat cool.
The top of stove can be used as a hot plate for boiling water and warming the food
of the workmen.
In the accompanying drawing the same letters indicate the same parts and the
various figures shew different views of one form of my apparatus.
Fig. 1 is a front elevation. Fig. 2 is a sectional end elevation through centre.
Fig. 3 is a sectional front elevation through centre. Fig. 4 is a plan view. Fig. 5 is
a sectional plan through centre of baffle plates over oven. Fig. 6 is a sectional plan
through centre of oven.
A is the furnace with door B and moveable firebars a of ordinary construction.
B is the firedoor hinged at b to the front plate of stove.
C is the oven with door D. The sides back and top of this oven are formed in one
piece and dropped into place from the top of stove, c is the bottom plate slid into place
through the doorway.
D is the door of oven C hinged at d to the front plate of stove. are the stops
to limit the opening of the door. The position of door when open is shewn by the
dotted lines.
E are the small flues formed by dividing the large ones into several small ones by
means of diaphragms e. The entrances el to these flues are kept small to prevent as
much as possible the coke getting into the flues and so choking them up.
F are the air chambers with holes through which the air can pass.
G is the flue at the top of oven with outlet g and baffle plates g¹.
H are flue doors for giving facilities for cleaning the flues.
In the foregoing description and accompanying drawing I have described and
illustrated the manner in which I preferably carry out my invention but I do not
bind myself to the exact details shewn. I may instead of three small flues at the
side of oven use two, four or more according to the size of the apparatus. Any
other shape of baffle plates that will answer the same purpose may be substituted for
the one shewn.
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
claim is :-
:-
1. The general construction of stove for heating tailor's irons substantially as
shewn in the drawing.
2. In stoves for heating tailor's irons, the mounting of the oven in such a manner
as to allow it free and independant expansion and contraction in all directions.
3. In stoves for heating tailors irons, the employment of two or
instead of one i.e. the subdividing of the flues so as to obtain a better distribution of
heat.
