An Improved Flat Iron.
EDWARD HEDGES, of the City of Saint John, in the City and County of Saint
John, in the Province of New Brunswick, in the Dominion of Canada, Mechanic,
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:-
This invention relates to improvements in flat irons, and consite partly in
the combination of the jet-block and jet-nozzle and a curved feeding tube.
The first part of my invention consists of the combination of the jet-block
and jet nozzle and a curved feeding tube.
The second part of my invention consists of the combination of a wire mesh
and trough for the purposes mentioned.
The third part of my invention consists of the combination with the handle
and body of a flat iron or similar utensil of a handle support which is also
intended to serve as a handle shield.
The fourth part of my invention consists of the special construction of the
reservoir and an air chamber and their combination with the feed pipe and
supporting devices.
The fifth part of my invention consists in the special construction and com-
bination of the means of supporting the burner and injecting gas, gasoline or
other fluid into the same with the various supporting and attaching devices.
The sixth part of my invention consists in bringing the gasoline feed pipe
into the body or interior of the implement and by curving the pipe therein,
forming the generator.
In the accompanying drawings,
Figure 1, represents a vertical, longitudinal, central section of a gasoline
heated flat iron embodying my invention.
Figure 2, represents a vertical, central section of a reservoir and air chamber
of a gasoline heated flat iron embodying my invention.
Figure 3, represents a view of the bottom of a flat iron furnished with a
trough device and accompanying wire mesh.
Figure 4, represents a detail sectional elevation of the tubular shaped jet-
block with projecting plug, and a screw threaded rod with a button on the
end thereof.
Figure 5, represents the box or case with a thread which is screwed to the
plug of jet-block.
Figure 6, represents the end of jet-block.
28 represents the wire mesh which fits to the bottom of said flat iron.
1, designates the hollow body of the flat iron, 2 its handle, 3 the support for
the handle which is attached to the ends thereof by a screw 4 at each end of
the handle and to the body 1 by screw 5 the said support being of sufficient
breadth to serve as a shield for the operator's hands against the heat arising
from the said body.
A standard 6 is provided with a foot 7 extending over the lower central part

page_text: of the said handle support for the preferably ellipsoidal shaped fuel reservoir 8,
which extends vertically from the said flat iron. The said foot is screwed in
place by two screws or bolts 5 and 40 which pass downward through the handle
support as aforesaid into the top of the flat iron. The upper end of said
standard 6 is the means by which the ellipsoidal shaped reservoir is fastened
to same. The reservoir consists of two hollow half ellipsoids equal in size
each one being rimmed at its widest circle and by these rims they are inter-
locked and soldered together around the circle running through 9, 9 thus form-
ing a complete hollow ellipsoid. A standard 10 passes vertically down through
the interior and centre of the ellipsoidal shaped reservoir. This standard 10
is a hollow half cylinder but at the lower end is cylindrical in
shape with a screw and is also cylindrical in shape and threaded
and clapped at its upper end. By passing this standard 10 as aforesaid
through the ellipsoidal shaped reservoir and screwing it to the lower standard 6
the ellipsoidal shaped reservoir is held firmly into place. The standard 10 is a
hollow half cylinder except the portion at its direct top and bottom where it
it in the form of a cylinder and by this means the gasoline runs through the
lower portion of the standard 10 through a wire mesh 41 for straining purposes
from the ellipsoidal shaped reservoir and passes down into the upper end of the
standard 6 into which a recess or pocket 11 is formed into which pocket the
upper end 12 of an outlet or discharge pipe 13 is introduced laterally and from
below. This pipe 13 which constitutes the gasoline feed pipe for the burner,
extends down along the standard to where it is first bolted to the flat iron
body and then passes downward through the upper part of the flat iron body.
It is then curved near the centre and top of said flat iron body after which it
enters the rear end of flat iron body and curves downward and enters the
tubular shaped jet-block 14 which jet-block also serves as a bearer for the
burner 17 and it is held in place by the small pinch screw 23 at the boring or
mixing chamber 15 leading to the outlet or discharge orifice 16. By curving
the said tubing in the interior of the said flat iron in the manner described an
automatic generator is obtained. The said packing box or case is hollowed
to receive the asbestos packing 18 and is screw threaded at its front end and
screwed to the rear end or plug 24 of said jet-block which compresses the pack-
ing as the same is screwed home thus preventing leakage from its rear.
In the centre of the bottom of the boring in the front end of jet-block is a
fine discharge orifice provided for the ejection of the fluid or vapor used as
a fuel. The plug 24 is tapped to receive a screw threaded rod 25 provided
with a button 26 at the outer end thereof for manipulation with the fingers in
controlling and regulating the flow of the fuel through the orifice 16. This
rod constitutes the valve stem and its inner end when screwed by means of the
button 26 against the valve seat closes the discharge orifice 16 which can be
opened by the reverse motion. A fine wire 27 is fixed into the inner end of
the valve stem 25 and moving with it inward and outward cleans the nozzle
or discharge outlet.
17 designates a cylindrical burner which is open at the rear end, the latter
fitting into the forward or inner end of the tubular shaped jet-block just
behind the usual air inlet 19 in the inner end of the latter.
20 designates a hinge lug forming part of the bottom 31 of said iron.
21 designates an opening in the front of said iron which fits over lug 20 and
a pin 22 passes through the end of said iron and the lug 20 thus forming a
hinge.
29 designates a clasp on rear of iron which holds the top and bottom of the
iron in place and is itself firmly held in place by the pinch screw 30.
At the highest point of the standard 10 at the top of the fuel reservoir 8
there is a screw topped oil inlet opening 32 receiving a screw ended half ellip-
soidal shaped air chamber 33 communicating with the fuel reservoir 8. At one
side of the said air chamber 33 there projects an air inlet screw 34 having an

page_text: inlet aperture 35 permitting the pumping of air to the interior of the air
chamber 33 the compression thus obtained driving the fuel in reservoir 8 down
through the discharge pipe 13 to the discharge 16.
Figure 3 is a top view of the bottom or base of said flat iron showing trough
(which is covered by the accompanying wire mesh 28 for retaining the heat
when in place) into which the gasoline or other fuel is injected by means of
the button 26 to be ignited for heating the generator formed by the curving
of the discharge pipe 13 in the interior of said iron as at 36 when the device is
to be started; 37 being air holes in the bottom of said flat iron to let in the air
to create a draught in connection with holes 38 drilled in the sides of the body
of the flat iron for the purpose of forming a perfect combustion.
To operate an iron such as described, unscrew the air chamber and fill the
reservoir 8 with gasoline or other fuel then screw on the air chamber 33 and
fill the same with air to a pressure of 5 or 10 pounds by means of any ordinary
air pump. Then unscrew the pinch screw 30 on top of clasp 29 and turn clasp out
as indicated by dotted lines and the top of the iron will then open from bottom
on a hinge. Now unscrew the valve stem 25 by turning the button 26 suffi-
ciently to inject a small quantity of gasoline into the burner from whence it
drops through small holes perforated in the bottom thereof into the trough.
Then screw in the said valve stem 25 to shut off the flow of gasoline ignite
the gasoline in the trough. Upon burning a few seconds the gasoline in the
generator turns to gas and by again opening the valve the gas escapes into the
burner and bursts from the holes bored therein in needles of flame forming
an automatic combustion with the heat of the flame directed to the bottom of
the iron and this combustion continues until the gasoline is exhausted in the
reservoir or the flow thereof is shut off by means of the button 26. As soon
as the needles of flame burst forth the clasp 29 is placed in position as in
Figure one and the pinch screw 30 tightened. In a few minutes the iron is
hot and ready for use.
