My invention relates to sadirons and particu
larly to electric irons wherein a detachable guard
supplied with a plug is ordinarily used for at
tachment to terminal posts on the iron. -Among
5 the objects of my invention is the provision of a
new and improved sadiron structure comprising
only must material costs be reduced to a mini
mum but the number of operations necessary to
assemble the parts must be made just as few as
possible and this can be accomplished in many in
ber adapted to serve as a support for the termi
nal posts and simultaneously provide a cover
stances by reducing the number of separate ln
dividual connections which must be made in or
der to secure all of the parts together. Another
factor which cannot be overlooked during this
simplifying process is the inevitable requirement

monly known as the heel.

appliances of this sort designed for household use.

and casing and which acts also in the nature of'a
columnar reinforcement between the sole plate
and the casing.
Still another object is the provision in an elec

nal posts and cover for the under side of the heel
has been provided a structural unit integral in
itself, serving a plurality of purposes and re 15
quiring a minimum of operations to install it in
an appliance. In the embodiment shown the part
in question is composed of a sheet metal stamping
formed substantially in the shape of the letter Z
as viewed in cross section providing a plate or
support at the top leg to which terminal posts
' which is made from a single stamping provided l -may be attached and extending rearward at the
with means'for engaging portions of the casing
and adapted to be clamped into position against
25 the sole plate of the iron bythe casing wherein
it is firmly supported by pressure and friction in
such a manner as to provide a solid base for the
terminal posts while at the same time acting as a
reinforcement for the casing or shell adjacent the
30 point where the terminal posts are attached.
With these and other objects in view my in
vention _ consists in the construction, arrange-~
ment and combination of the various parts of my
device whereby the objects contemplated are at
ß' tained as hereinafter more fully set forth and
pointed out in my claims and illustrated in the
accompanying drawing in which:
extending rearward to form what is known as a
heel or heel rest.
As shown in the drawings an electric iron hav
ing a base A is provided with a handle B for
manipulating it over an ironing board. A control
D is provided for turning the iron on and off.
The 'base -ls composed of a sole plate III within
which is embedded a heating element i2 and sur
mountlng the sole plate is a weight member Il at
tached thereto. Above the sole plate and weight
is a shell or casing I6 which entirely covers the 35
base portion of the iron and extendsy rearward at
Il in the form of a hollow heel or heel rest. The

Inthe construction of _electric sadirons many
-factors must be taken into-v consideratlon when
` ' it is desired to build a ‘rugged structure which be-`
55- 'cause ofl weight of the iron alone is subjectto a
î great deal of strain and abuse. It is furthermore
essential to reduce the manufacturing cost of de
'vices of this_.sort to a figure as low as possible in
order that the manufacturer may be able to meet
I competition inthis highly developed art. Not
above describedeis positioned and is designated
by the character 3l. 'I‘he upper leg of the Z
shaped stamping formed in the shape of a plate
32 lies adjacent the casing partially closing the
plate Il
and the

end with a lug 36 vadapted to engage a

the casing. Formed also on the plate are a pair
in which are a pair of apertures 44.

means for engaging a portion of the casing and
locating means for -positioning the leg in the
of projectionsl 48 designed to position the plate
Within the opening 28. As viewed in Fig. 4 the
plate 32 has a central'slightly dished portion 42
and 34.
At the upper- end 48 the element is
rounded slightly where it presses against the
10 bottom of the casing I6 adjacent the hole 28.
-The lower plate 34 extends rearward substan
tially horizontal-'to the soleplate and is provided
with a flange 58 extending downward to add ri
gidity to the plate and is provided also with an
16 upward extending rim 52 which ñts snugly within
‘edge of the heel I8.
The upper plate 32 extends almost completely
across the opening 28 forming a rigid bottom for
the opening supported at both front and back
20 upon which the pair of terminal posts 54 previ
ously referred to are mounted. 'I‘hese are insu
lated from the plate by a series of mica. washers
58 and are held in place by a nut 58. Ample
clearance is provided between the terminal posts
25 54 and the adjacent edges of the holes 44 in the
«plate for insulating purposes. The terminal
pests are connected by wires 60 to the heating
element of the iron and a guard 62 protects the .
posts from accidental blows which would tend to
knock them out of alignment.
When the device is assembled the terminal
posts are mounted and tightened into the holes
44- of the combined terminal support and heel
cover which is then positioned upon the sole plate
on a shelf at the rear indicated as numeral 62
and in this position the lower leg 34 extends rear
wardas previously described. The lug 26 on the
plate 32 is then positioned in the depression 38
provided for it adjacent the hole 28 in the casing
and the shell or casing is then lowered into -place
over the sole plate and there attached. Attach
ment consists of pressing the Z shaped member
30 between the casing and the sole plate and
supporting it at one end by üie lug 36. During
45 the operation the-»rim 52 of the Zshaped plate
is engaged frictionally within the inside portion
of the hollowfheel plate. The Z shaped part by
the means described is securely clamped between
stationary parts forming a base for the iron.
Once the „parts are in place the insulated ter
minal posts 54, become ñrmly attached to the
casing by means of the rigid positioning thereon
of the part 30 and its upper plate 32. Due to
the support provided by the lug 38 resting lupon
-the shell and the somewhat columnar support of
the cross bar 46 the dished portion 42 supporting
the terminal posts is made extremely rigid when
once secured in place. The central bar A46 by
resting at one end on the sole plate and at the
60 other end against the shell, forms a spreader and
reinforcement for the shell at a point of contact
which is adjacent the terminal post opening 28
serving thus an added purpose.
Some changes may be made in the construction
and arrangement of the parts of my device with
cut departing from the real spirit and purpose of
my invention and it is Amy intention to cover by
my claims any modiñed forms of structure or use
of mechanical equivalents which may be reason
ably included within their scope.
