The invention appertains to a sadiron heated
by an alcohol burner and has for its general ob
liect to produce an improved heating unit that
not only is simple of construction but also is eco
5 nomical of operation.
More particularly the invention aims to provide
a safe and reliable generator and burner tube
combined as a unit with the fuel storage tank.
The parts are so associated that they are detach
10 ably mounted as a unit in the body of the sadiron.
A distinctive feature lies in the mode of mountn
ing the unitary members and securing them in a
detachable manner.
Th-e invention will be better understood by ref
15 erence to the accompanying drawing in which
Figure l isa side elevation of the sadiron.
Figure 2 isa rear elevation viewed on the line
2-2 looking in the direction of the arrows and

(Cl. 15S-23.2)
To start the burner in operation, external heat
is applied by a pilot or other knwn means to va~
porize the volatile fuel in the generating cham
ber. The gas flows down the burner tube, com
mingles with air admitted by the perforated part 5
i3 and burns injets emanating from the holes i i.
The burner tube, valve and tank are referred to
as a unitary heating unit. The mode of detach~
ably mounting this unit in the body comprises the
provision of the slot 2t extending inwardly from 10
the top of the rear face 2d of the body. The valve
is supplied with a pair of spaced flanges 25 at
each side so as to define respective intervening
recesses. Therecessed portion of the valve is in«
serted in the slot 23 so that the flanges shoulder 15
it on the body and thus mount the heating unit
in proper position.
To secure the heating unit in position, a lock
ing plate 26 is employed, which plate is disposed
adjoining the rear face 2li and pivoted at 25 to
one side of the body for swinging movement in a
