PROVISIONAL SPECIFICATION.
'Improvements in Gas-heated Smoothing Irons.
I, ANDREW HISLOP MACLEAN, Chairman of the Air-burning Company,
Limited, of 40 North Albion Street, in the County of Glasgow, Gentleman, do
hereby declare the nature of this invention to be as follows, that is to say :—
My said invention has for its object to improve the construction of gan-heated
smoothing irons, so as to economise gas, and to be convenient in use and without
objectionable exhalation.
My improved implement comprises a simple box of cast iron or other suitable
metal made with two opposite smoothing surfaces each of any suitable form for
smoothing purposes. In the longitudinal axis of the box thero is a burner pipe
made with jet orifices on its upper side; and the box is fitted so that it can be
turned over on the pipe as an axis to put either smoothing surface undermost.
One end of the pipe is closed; and the other end of the pipe is turned up and its
end is adapted to receive a flexible gas-supply pipe. On the turned up part of
the pipe thero is fitted an encircling perforated air-inlet ring such as is used with
an ordinary Bunsen burner, the usual jot nozzle for the gas being fitted within the
same part of the pipe. The turned-up part of the pipe also serves as a support for
one end of the handle, the other end of the handle being supported by a piece
fixed to the closed end of the pipe; and at the same end of the pipe there is a
spring catch or bolt arranged to lock the box in either of its two positions. Along
the sides of the box there are rows of perforations or slits near each smoothing
plate. When the mixture of gas and air from the Bunsen device is lit within the
box the burning jets act directly on the smoothing plate which is uppermost at the
time, the gaseous products of combustion escaping through the perforations_near
that plate, whilst additional air can enter through the lower perforations. When
the top smoothing plate is sufficiently heated, the box can be turned half round,
thereby bringing the opposite smoothing plate into position for being heated.
The flexible supply pipe may have its end applied in the ordinary way over a
common gas burner of a bracket or other pipe; 1 however prefer to provide a
curved motal tube having a tapered screw at one end which can be screwed tightly
into the socket made to receive an ordinary gas burnor, the flexible pipe being
applied to the other end of the curved tube.

Improvements in Gas-heated Smoothing Irons.
:
I, ANDREW HISLOP MACLEAN, Chairman of the Air-burning Company,
Limited, of 49 North Albion Street, in the County of Glasgow, Gentleman, do
hereby declare the nature of this invention and in what mannor the same is
0 to be performed, to be particularly described and ascertained in and by the
following statement, that is to say :—
My said invention has for its object to improve the construction of gas-heated
smoothing irons so as to economise gas, and to be convenient in use and without
objectionable exhalation.

My improved implement comprises a simple box of cast iron or other suitable
metal made with two opposite smoothing surfaces each of any suitable form for
smoothing purposes. In the longitudinal axis of the box there is a burner pipe
made with, jet orifices on its upper side; and the box is fitted so that it can be
turned over on the pipe as an axis to put either smoothing surface undermost.
The invention also comprises improvements in the details of the implement.

And in order that my said invention and the manner of porforming the same
may be properly understood. I hereunto append a sheet of explanatory drawings,
to be hereinafter referred to, and showing a gas-hoated smoothing iron as mado
with my improvements.
Figures, 1, 2, and 3, of the drawings are respectively a plau, and side änd-'end
elovations.
Figures, 4, nud 5, are a horizontal section and a longitudinal vertical section.
Figure, 6, is a view of a detail.
In these drawings the same reference letters are used to mark the 'same or like
parts wherever they are repented.

My improved implement comprises a simple box, A, of cast iron or other suitable
metal made with two opposite smoothing surfaces each of any suitable form for
smoothing purposes. In the longitudinal axis of the box, A, there is a burner
pipe, B, which may be made partly or wholly of cast iron or copper or other
material and with jet orifices, C, on its upper side; and the box is fitted so that it
- can be turnod.over on the pipe as an axis to put either smoothing surface under-
most. Ono end of the pipe, B, is closed; and' the other end of the pipe is turned
up and has fixed to it a smaller pipe, F, the upper end of which is adapted to
receive a floxible gas-supply pipe, D. On the turned-up part of the pipe B, there
is fitted an encircling perforated air-inlet'ring, E, such as is used with an ordinary
Bunsen burner, the usual jet nozzle, G, for, the gas being fitted within the same
part of the pipe. The turned-up. part of the pipe, B, also serves as a support for
one end of the handle, H, the other end of the handle being supported by a
L-piece, J, fixed to the closed end of the pipe, B, a screwed projection, K, on it
passing through the end of the box for the purpose. A piece, L, fixed to the back
end of the box and which forms a bearing for the projection, K, is made with n
crank arm, M, having fitted to, it a spring catch or Bolt, N, the crank arm serving
to turn the box and the spring bolt to lock it in either of its two positions. Along
the sides of the box, B, there are rows of perforations or slits, R, near each
smoothing plate, the perforations or elite being partially closed by wire gauze, P,
-with-which the inside of the box is lined. When the mixture of gas and air from
the Bunsen device is lit within the box the burning jets, C, act directly on the
smoothing plate which is uppermost at the time, the gaseous products of combustion
escaping through the perforations, N, near that plate, whilst additional air can
enter through the lower perforations. When the top smoothing plate is sufficiently
heated, the box can be turned half round, thereby bringing the opposite smoothing
plate into position for being heated. The box, A, consists of two parts, one part
coinprising one smoothing surface nad the back end, and being fixed by screws to
the other part.
•
The flexible supply pipe, D, may have its end applied in the ordinary way over
a common gas burner of a bracket or other pipe; 1 however prefer to provide a
curved metal tubė, Q, having a tapered Ferow at one end which can be screwed
tightly into the sopket made to receive au ordinary gas burner, the flexible pipe
being applied to the other end of the curved tube.

Having now particularly described and ascertained, the nature of any anid inven-
sh. tion and in what manner the same is to be performed, I'declare that what 1
claim is :-
1.The combination and arrangement of parts constituting the 'improved gas-
heated smoothing iron substantially as hereinbefore described.

page_text: surfaces and capable of being turned on a burner pipe, forming its longitudinal
axis, and made with jet orifices, so as to place and hold either smoothing surface
undermost substantially as and for the purposes hereinbofore described.
