My present invention relates to improvements
in ironing machines of the type employed for
ironing the tubular portions of garments such
as legs and sleeves and, in the particular form
5 herein illustrated and described, is particularly
adapted for the ironing of garment sleeves.
Otherwise stated, the invention relates to im
provements in ironing devices of the type dis
closed in prior Patents Nos. 1,937,656 and 2,022,
210, the former of which was issued jointly to
myself and George H. Leef on December 5, 1933
under the title of “Garment leg ironer,” and
the letter of which was issued jointly to myself
and George H. Leef on November 26, 1935 under
the title of “Garment sleeve ironer.”
Among the important objects of the invention
is the provision of a machine of the kind described
that can be more quickly and easily manipulated
than similar machines of this character. The
90> above and several other important objects of the
invention will be made apparent in the following
speciñcation and claims.
In the accompanying drawings like characters
indicate like parts throughout the several views.
Referring to the drawings:

with some parts shown in full and some parts
broken away, taken on the line I-I of Fig. 2,

ating relatively movable boots Ill are connected
`to and supported from their respective co-oper 10
ating fixed boots 9 by links I2, which links are
pivotally connected at their lower ends to the base
portions of the ñxed boots at I3 and to the upper
intermediate portions of the movable boots II) by
pivot hinge pins I4. The `co-operating boots 9
and I Il thus mounted, one with respect to the
other, will automatically adapt themselves to rel~
ative positions necessary to accommodate different
sizes and shapes of garment sleeves; and since
it is desired to permit the boots 9 and I8 to be
brought'into face-to-face Contact when neces
sary, the opposed inner faces of the boots 9 and
I0 are preferably provided with recesses I5 and
I6 for reception of the connecting links I2.
Under the action of gravity the movable boots
I0 will normally tend to move away from their
respective co-operating boots 9 on the arc of a
circle struck from the points of pivotal connection
between the links I2 and ñXed boots 9, and the
tendency will be for the movable boots I0 to 30
move on this movable arc until the lower ends of
the boots I0 come to rest upon the table top 1.
However, in practice the resilient steam connec
tions to the movable boots, which will hereinafter
be described in detail, usually exert suiñcient re-l 35

slightly above the table top. Nevertheless, it will
be obvious that in the absence of sufficient resist#

removal operations. In the preferred embodi

thereof and the rear wall of the notches 2| are
compression springs 25 which normally keep the
ends of the pressing rods i3 pressed outward to
the maximum extent permitted by the stop shoul
ders 24, but which springs 25 will yield readily
under contracting pressure exerted by a garment
sleeve and will permit the upper ends of the
forming rods i8 to be drawn up tight against the
faces of their respective boots il! or to any inter
mediate positions.

tracting mechanism is foot-operated and com
prises an intermediately pivoted operating lever

The sleeves of the shirts of various different

grades and makes vary greatly in shape. Some,
25 namely, the lower quality work shirts, taper
straight down from the shoulder to the cuff diam
eter at the cuffs; whereas, sleeves of higher qual
ity shirts such as dress shirts, usually have much
less taper and at their points of attachment to
the cuffs are of considerably larger diameter than
the cuffs themselves. Still other shirts have
sleeves which are substantially of uniform diam
29 provided therefor in the table top 1, see par
ticularly Fig. 1. The lower end of push rod 21
is pivotally anchored to the inwardly projecting
end of the lever 26 at 30. The intermediate por

Under foot pressure applied by the operator to
would be practically impossible to select any
shape pressing boots which would be capable of
conforming to the shape of all the different sizes
and styles of short sleeves encountered in gen
40 eral laundry practice, but such difficulty is largely
done away with in the preferred embodiment of
this invention herein illustrated and described by
the combined automatic shifting actions of mov
able boots Ill with respect to their co-operating
45 boots 9 and the yielding action of the forming
rods I8.
In this connection it Will, of course, be under
stood that when a sleeve is pulled over a pair of
co-operating boots S and I9, shoulder end first
and seam adjacent the forming rods I8, the mov
able boots IU, after being shifted toward their
co-operating fixed boots 9 to permit free appli
cation of the sleeve, will move outwardly under
the action of gravity until they tightly engage the
sleeve and maintain the same under expanding
pressure against the surfaces of the boots, and
the upper ends of the forming rods will compress
their co-operating springs 25 and recede into the
tion of the lever 26 is pívoted on a cross rod 3|
that extends at opposite sides of the frame-like
structure 8 and is held axially centered on said 30
rod 3| by opposed spacing tubes 32.
the lever 26 is provided at its outer end with a
to the pedal-equipped end of the lever 2E, lifting
pressure will be applied to the movable boots l0
through the forked push rod 21, and under this
upward lifting pressure the movable boots I0
will tend to move upwardly and toward their 40
respective co-operating fixed boots 9 on the arcs
of circles struck from the pivot points I3 until
the upper ends of the co-operating boots come
into engagement, at which time application of
the sleeve will be very quickly accomplished.
After the sleeve has been applied and the foot
pressure released, the parts will then assume
positions necessary for complete smoothing out
of all the sleeve surface. Since the upper ends
28 of the push> rod engage the base portions of
the movable boots lil onlyl with frictional surface
engagement, movements of the lower ends of
the boots l0 will be permitted even when lifting
pressure is applied to the boots and lever 26 of
the push rod.

The steam chambers’within the hollow shell
like boots 9 and ID of boot pairs A and B are
supplied with suitable heating medium, which
heads of the boots H3 as far as is necessary to ac
will usually be live steam in the manner pres
commodate sleeves of any particular cuff dimen
ently to be described. These steam chambers 60
of the several boots are each provided with con
centric steam inlet and outlet ducts, and the
sion; and the intermediate and lower portions
of the forming rods i8 will shape themselves to
conform to the shape of the seam edge of any
seam shape. The net result of the above is the
F uniform stretching or shaping of substantially
any sleeve shape all the way from cuff to shoul
der without leaving any ruffled or loose portions,
so that the finished product is substantially free
from imperfections usually considered as a nec
essary result of machine work.
Preferably the rear sides of the ñxed 1boots S,
which engage the sleeve diametrically opposite
the seam edge thereof, are straight or substan
steam chambers of the several boots are con

at its lower end with a conventional T-coupling

form may be varied.
In the machine illustrated
several boots 9 and I0 has projecting downwardly
from the screw threaded into its bottom portion
a pipe-like section. For the purpose of identiñ
cation the said outlet pipe sections for boots 9
and I0 of boot pair A are respectively indicated
by 9a` and lila and said pipe outlet sections for
boots 9 and I0 of boot pair B are respectively in
dicated by 9b and lûb‘. Each of the several out

in the table top 1, so that the said pipe sections
Willnot interfere with free oscillatory movements
of the movable boots.
Steam> is introduced through the serially con
nected series of boots through a primary inlet
pipe 36 which is screw threaded into the lower
vertical opening of the T-coupling 34 that is car
ried by the outlet or discharge pipe 9a of fixed
boot 9 of pair A. Projecting concentrically from
the upper end of the primary inlet con-duit 36
and through the associated coupling 34 and out
let duct 9a and into the upper portion of the
steam chamber of boot 9 of pair A is a relatively
15 small diameter conduit 31 in the nature of a
drawn copper tubing. This conduit 31 is secured
in the end of the conduit 36 by a conventional
_ compression type fitting 38 which tightly seals
the space between the small diameter conduit 31
20 and the larger internal diameter of the primary
inlet pipe 36. Steam delivered through the pri
mary inlet pipe 36 passes upwardly through the
small diameter conduit 31 to the upper extremity
of boot 9 of pair A and then passes downwardly
through the steam chamber of said boot around
the outside of said conduit 31 and discharges
from the boot 9 of pair A through outlet conduit
9a into the intermediate portion of the asso
ciated T-coupling 34. The horizontal opening
30 of this last noted T-coupling 34 is connected
through the medium of a compression type ñtting
39 to a small diameter conduit 40, which ex
tends through the bottom of coupling 34 of con
duit 10a through the center of conduit Iûa and
to the upper extremity of the steam chamber of
boot pair A. This pipe coupling 40 is secured in
the coupling 34 of conduit 10a by a compression
type fitting 4l. By means of this connection
steam discharged from the boot 9 of pair A is
delivered to the boot I0 of pair A, and steam
discharged from boot ID of pair A through cou
pling lila is delivered to the upper extremity of
boot I9 of pair B by a small diameter tubing or
conduit 42, which tubing is made fast in T-cou
pling 34 in conduit loa by a compression fitting
45 43 and is made fast in the T-coupling 34 of con
duit lllb by a compression ñtting 44. Steam
delivered into the boot IBI)` through the conduit
42 will be discharged through the conduit Illb
into the associated coupling 34, from where it
50 will be delivered through a small conduit 45 to
the upper extreme portion of the steam cham
ber of boot 9 of pair B. Conduit 45 is made fast
in the associated couplings 34 by compression
fittings 46 and 41. Steam thus delivered into the
55 steam chamber of boot 9 of pair B will be dis
charged through pipe 9b~ into the associated
coupling 34 and from thence will be discharged
through a suitable ñnal outlet pipe 48.
As previously indicated, the conduits 40, 4Z
60 and 45 are preferably of drawn copper tubing
which is quite ñexible, and in order to increase
to a maximum the flexing action of the portions
of these conduits which connect to either of the
movable boots I0, these portions of the conduits
65 40, 42 and 45 are coiled, as indicated in Figs.
1, 2 and 3. Interposed in the ñnal outlet pipe
48 is a steam-control valve 49.
In the preferred embodiment of the invention
illustrated the table top 1 is provided with a
70 pair of stop lugs 50, one thereof being located
back of the base portion of each of the boots
I D and so positioned as to be engaged by the
lower portions of the boots l0 under maximum
desired outward oscillating movements thereof
and to prevent excessive outward oscillation of
the lower portions of said boots.
With the structure above described, it is evi
dent that while the movable boots will be simul
taneously lifted and caused to approach the co
operating fixed boots, under the action of the
lifting device afforded by the push rod 21--28,
nevertheless, that the independent supporting
links i2 and the loose or slip connection between
the rod prongs` 28 and the bottoms of the mov
able boots I0 permit the latter, when manually
pressed by the application of a garment leg,
sleeve, or the like, to approach the co-operating
fixed boots and thus adapt themselves to legs
or sleeve structures that differ in cross-section
and taper.
What I claim is:
l. In a device of the kind described, the com
bination with a table-like supporting structure,
of a pair of co-operating upright pressing boots,
one of which boots is relatively fixed to said sup
porting structure and the other of which boots is
