'I'he ironing machine ‘shown in Figures 1 to 12
is of the type which is adapted for domestic use.
The machine is provided,with a stand or support
ing structure including a base member I, carried
on supporting legs 2 which may be provided with
15 casters (not shown) to facilitate the movement
of the machine about from place to place. A
combined motor cap and ironer supporting mem
ber 3 is flxedly secured at one side to the base
. member I and at its opposite side it is secured to
20 the stator stack 4 of an electric motor which is
provided for driving the ironer.
n
A switchl having an operating member 5 at the
front of the ironer is provided for controlling the `
to be described in detail presently. 'I'he opposite
end 38 of the member 31a/provides an abutment for
the spring 3|.
During the operation of themotor the driving
clutch member 24 rotates continuously. The ac
tuation of the clutch control member 35 and the
engagement
and . disengagement
between the
driving and driven clutch members 24 and 25
respectively is effected by means of a shiftable
plate-like member 39 having offset stops 40 and 4|
which can be moved into and out of the path
described by the oil’set part 31 during its rotation
about the axis of the shaft 20.
The stops 40 and 4| engage the part 31 at points
spaced substantially one hundred and eighty de
grees apart with respect to the circular path
traveled by the member 31 about the axis of the
shaft 20. Normally the member 39 is maintained
so that its ~stops 40 and 4I are in the path of travel
of the offset part 31 of the clutch controlling 20
member 35 to hold- the same ina position corre
sponding toits clutch disengaging position.
The following action of the parts, shown best in '
operation of the motor. Fixedly secured to the
25 upper side of the stator 4 of the motor, there is
Figure 2, takes place during the disengagement
secured an integrally formed combined cast metal
motor cap and gear case 8. The part 6 houses
most of the operating mechanism of the machine
of one‘ or the other of the stops 40 or 4I causes the
and it supports an ironing roll 1 having suitable
30 padding 8 and a shoe i8 having an electric heat
ing element || and rear cover |2. The current
supply of thel heating element of the shoe is con
trolled b‘y means of a switch (not shown) which
' is located alongside of and behind the motor con
trolling switchS shown in Figure l.
The casting 6 has a centrally bored boss |3
which provides a bearing for the shaft |4 of the
electric motor, such shaft being provided at its
outer end with a worm I5, meshing with a worm
gear I6, which is mounted‘for rotation in the
casting 3. 4'I'i'ie worm `gear I8 is threadably se
cured to a cup-shaped clutch member I1 having
an axially extending part I8 which is keyed at i9
of the clutch. The part 31 upon~initial contact

roller 30 compressing the spring 3|. 'I'his move
ment is made possible by reason of the loose flt of
the member 35 about the shaft 20. As viewed in 30
Figure 2 when the member 35 contacts with the
upper side of the shaft 20 further compression of
the spring 3| is prevented and the finger 36 then
moves the roller 30 out of connecting engagement
with the cam face 21 and the inner surface of the 35
rim 24, thereby disengaging the driving connec
tion between the driving and the driven members
of the clutch.
Upon the stoppage of the driven parts of the
clutch the spring 3| operates to further move the 40
roller an additional amount from its initial re
leased position until the clutch control part 35
assumes the position relative to the shaft 20 as
to a shaft 20. 'I'he opposite ends of this shaft are
illustrated in Figure 2 of the drawings, whereupon

serves as one of the driving elements of a roller
type clutch, the driven element of which is formed
by a member 28 having cam faces 28 and 21 and
coacting rollers 28 and 33.
_
hThe roller 28 coacts with the cam face 28 and
the rim partv 24 to provide driving connection
between the clutch parts for movement in one
direction and the roller 33. coacts with the cam
60 face 21 and the annular rim part 24 to provide
driving connection between the clutch parts for
movement in an~ opposite direction. Suitable
springs 3| and 32 having associated plungers 33
and 34 are provided to urge the rollers 28 and 30
end of the clutch and serves as a cover therefor. 50
The purpose of arranging and operating the
aforesaid clutch parts in the manner described
is to prevent frictional drag between the driving
and the driven clutch parts when the clutch is
disengaged. In the present construction the 55
spring 3| has the added function ofl moving the
roller 30 to a completely disengaged position with
respect to the cooperating driving and driven
clutch parts, therebyv eliminating frictional drag
in the clutch and also preventing overheating of 60
the clutch by reason of such frlctional drag.

other end in any suitable manner,`such as by
means of the pin 45, to the slidable clutch con
10 trol plate 39. In a similar manner a pin 46 is
used to secure a plunger rod 41 to the opposite
end of the plate 39. A spring 48 is- carried at
`this point to normally maintain the plate 39 in
the position shown in Figure 3 vof the drawing
15 which position corresponds to the position of dis
engagement for the clutch. Oil seals 49-49 en
gage with the plunger rods 44 and 41 to prevent
the escape of lubricant from the gear case cast
ing 6.
20
The plunger 41 is slidably carried in a threaded
coupling member 50 which serves as a support
means for one end of a flexible conduit 5| within
which there is provided a flexible control wire
52 which is secured at one end by means of a
25 threaded member 53 to a similarly threaded end
part of the rod 41. The other end of the flexible
threaded ends of the rod 68 are locked in their
adjusted positions by means of a pair of lock nuts
13-13. Preferably the ends of the rod 688 are 10
threaded so that the twisting the rod is subjected
to will tend to further tighten the nuts 13 and if
desired other meansy may be used for insuring the
locked engagement between the rod and the mem
15
bers attached to its ends.
The gear case casting 6 is provided with a
laterally extending hollow boss 14 in which is
rigidly iitted one end of a supporting tube 16. In
the opposite ends of this tube are lfitted bush
ings 16 and 11 which provide bearings for the 20
tube 61. A pair of crank members 188 and 19
are rotatably mounted on the outer -end of the
tube 61 Iand they are held in position thereon by
any suitable means such as a bolt -88 threaded into
the outer end of the tube 61. A T-shaped slot 25

of the arm 1| of the crank 18.
The torsion rod 68 acts as a spring for pro
35 spring 6|, the other end of which abuts against' viding resilient pressing engagement between the
the underside of the supporting iìxture 56.`
From the foregoing it is apparent that the driv
ing engagement between the cooperating clutch
members 24 and 25 may be readily eiïected by
pressing either the hand button 43 or the foot
button 51 whichever happens to be most con
venient for the operator or for the class of work
being ironed. In the actuation of the aforesaid
buttons they are. pressed in only momentarily.
45 This operation permits the driving and driven
clutch parts 24 and 25 to move into engagement
with respect to each other for upon release of the
finger 31 the spring 32 moves the roller 38 into
frictional engagement with the »cam face' 21 and
50
the rim 24.
'
l'
'
The driven clutch part is then rotated `about
one-half turn until the finger-31 engages one or
the other of the stops or offset parts 40 or 4|
of the control plate 39 whereupon the disengage
55 ment of the clutch parts is effected in the manner
previously described and the driven clutch part
25 remains stationary until the aforesaid clutch
controls are again operated. The movement of
the driven. clutch part serves to drive the cam
60 42 which is ñxedly secured'to the driven clutch
part 25 by any suitable means such as the
rivets 62.
The cam 42 is in contact engagement with a
roller 63 rotatably carried on one end of a lever
65 64 which is rigidly secured by means voi' a pin 66'
to a rotatably mounted tubev61 and a spring
torsion rod 68. The roller 63 of the crank 64> is
maintained in contact with the cam 42 by means
of a spring v65 which abuts at one end in a suit
70 able pocket formed in the gear case casing 6
and which at the other end is received in a suit
able recess provided by the crank arm 64.

ironer shoe andthe ironer roll. The adjusting
screw 12 is provided to pre-load the torsion rod
68 to provide a' predetermined pressure between
the vroll and shoe when they are in engagement
with each other. This pre-loading of the rod is 40
made possible by reason of the fact that >the ends
of the rod 68 and the tube 61 are rigidly Vsecured

member 18 which is ñxed to the end of the rod 45.
68 engages with the arm 84 of the crank member
18 which is journaled on the end of the tube 61i.
The crank 18 has a set screw 83 which normally
contacts with one end of the crosswise part of
the T-shaped slot 8| so that the tube -81 and’ 50
the crank arm 84 of the crank 18 can oppose
the twisting moment of the torsion spring 88.
The crank arm 84 is connected by means of
an end-threaded stud shaft 85 to one end of a
toggle joint formed by a pair of toggle links 86
and 81 which are pivotally joined to each other
by means of ‘an end-threaded stud shaft 88. At
its outer end the link 81 is pivotally secured by
means of an ‘end-threaded stud shaft 89 to the
arm 90 of the crank member 19 which is journaled 60
on the outermost end of the tube 61. Another
arm 93 of the crank member 19 pivotally carries
the ironer shoe I8 at its outermost end.
The shoe I8 is flexibly secured ata point inter
mediate its' length to the arm 93 by means of a
pair of rearwardly projecting relatively resilient
yielding ears 94-94 ñxed to the shœ and which
have non-circular openings 95 for receiving cor
respondingly formed notched ends of a pin 96,
the intermediate part of which is formed with a
channeled or grooved part 91, the ends of which
are arranged to engage with a screw 98 iixedly
carried by the arm 93 of the crank 19. The end
of the screw 98 cooperates with the ends of the

the lever |30 is pivotally connected by a pin |32
to a link |33 which in turn is pivotally connected
by the stud shaft 88 to the point Where the toggle
links 86 and 81 are joined to each other. These
links normally are out of line a slight amount and
thus have a tendency to press against an adjust
able screw |34 which is threadably received in the
crank member 18. Under ordinary operating con-’

The breaking of the toggle joint requires the ex

In the modified form of construction shown in
Figures 13 to 22 of the drawings, the ironing
machine illustrated follows in general the form

supporting tube |6| and the latter of which is
rigid with and surrounded by a boss |62 of the

In so far as the improvements of the machine ‘ shown in Figure 15 of the drawings.
This arrangement provides a safety release
shown ln Figure 13 are ‘concerned mainly with the
shoe and its supporting means, further reference for moving the shoe away from the roll and it
will not be made to the operating mechanism of , also serves to utilize the rn'achine as a pressing

The shoe |42 at its rearward side is provided gagement. A stop |18 carried by the member I1 I .
engages the lever |68 when the toggle is moved
with a pair of ears |45--~|45 of‘slmilar construc
tion to the shoe supporting ears mentioned in to its locked or aligned position. In practice it is

and it comprises' a table-like structure |40 for
shown in Figures 1 to 12 andsuch ears are pro
with the stop |12, to have the toggle normally
‘ vided with non-circular holes |46.--|46 for re
out of alignment a slight amount so that there
is a tendency to maintain the aforesaid parts in
ceiving the notched ends of a shoe supporting
pin |41 which is rigidly secured to the ears by
means of a pair of bolts |48.
`
The pin |41 is provided with a circumferen
tial channel> |50 intermediate its length which
extends part way around the pin axis. The
grooved‘part of the pin is received in a suitable
bearingprovided‘at the upper end of a shoe sup
porting arm |5| whichis drilled and threaded for
the reception of a screw |52. The end of this
screw projects into the channeled slot |50 of the
pin |41 and the screw _thus serves to limit the
movement of the shoe about the axis of its pin
|41 so that the shoe may be rotated to present
its surface in a position corresponding. to the
this position.
_
The torsion rod |56 is ordinarily pre-loaded a
slight amount -which loading may be varied by
means of an eccentric part |14 formed on the
stud shaft |65 which eccentric part is journaled
in the lower end of the crank- |63. An adjusting ,
member |15 having a rectangular hole for recep
tion of a similarly formed part of the stud shaft
|65 is provided for adjusting the eccentric |14.
This member has an operating handlev |16 which
is held in various desired positions of adjust
ment by means of a series of notches |19 formed
in the rearmost end of the toggle member |88.
The adjusting member |15 is urged against this
position shown in dotted lines for the form of the y lend of the toggle member by means of a spring

|82 which is threaded into the bearing |58 is
used to secure the hollow casting |83 to the base

|83 also assists in supporting the shoe of the
machine, in stiiîening the base |40 and in
strengthening and increasing the rigidity of the
entire supportingv structure of the ironing ele
