Application November 9, 1932, Serial No. 641,835
3 Claims. (Cl. 38-81)
The ironer to be described is of the power driven,
roller type, the general ‘arrangement consisting of
' 5
a roller contacted by a movable ironing shoe, the
said roller being supported upon a member ex
tending from the frame of the head mechanism,
which is in turn suitably attached to and sup
ported by a bench or table 6 I , as clearly shownin
Figs. 1 and 2 'of the accompanying drawings.
Power for driving the several elements is fur
10 nished by a conventional motor through mecha
nism and controls to be described, the whole form
ing a complete working unit.
.
‘The main object of the invention is to provide a
power driven ironer of the roll type which is par!
15 ticularly suited to domestic use.
Another object is to provide an ironer which
may be e?iciently operated by inexperienced per
sons with a minimum of physical effort.
A further object is to provide any ironer having
20 an independently controlled power driven roller
and an independently controlled power operated
ironing shoe adapted to be placed in contact with
or withdrawn ‘from the roller.
Another object is to provide a power operated
25 shoe which is automatically withdrawn from con
tact with the roller when rotation of the roller is
discontinued.
A still further object is to provide an ironing
shoe which when placed in contact with the roller
by the operated power means, may be removed
from such contact by manual means without dis
turbance of the power operated means.
Other and further objects will appear in the ac
c'ompanying description and drawings, in which—

As already mentioned, the ironing roller is 25
power driven, the source of power being a con
ventional electric motor located ‘within the hous
ing projection I clearly shown? in Figs. 1 and 2.
The motor being of standard manufacture, will

as viewed in Fig. 7, is ?xedly mounted a spur
pinion Hi. It will be apparent that shaft I1 is
and contact with the ?anged portion thereof, as
clearly shown in section in Fig. 7.
At its upper end lever 21 terminates in an off
set portion having a circular opening so dis
posed as to loosely receive the body of a sleeve
nut 29 which is adjustably attached to a shaft
33 by means of a threaded portion, the head of
supported, at the left hand end, -by and within . nut 29 acting as a shoulder to retain lever 21,
sleeve l2, while the right hand end is rotatably as shown. The shaft 30 is slidably mounted in
10 and slidably mounted in bushing I3’, which lat
a bearing 3| supported by extension from frame 10
ter is supported by frame member l5. From member l5.
.
'
the above description, and consideration of parts
To the end of shaft 30 opposite the screw 29 is
shown in Fig. '1, it will be clear that sleeve I2 a?lxed a washer member 32, so formed and dis
is supported at the left hand end by bearing posed that its upper side is adapted to contact
15 ll-IS.v above describedytand at the right hand ‘with the stepped portion of rotatable member 15
end by shaft H, which latter is supported at the 25'. To prevent rotation of shaft 33, the lower
right hand end by bearing |8—|5, above de
edge of said washer 32' is formed to complement
scribed, and at the left hand end by and within the contour of an extended portion of housing
the sleeve l2. Thus, it will be clear that sleeve It and disposed in a slidable relationwith said
20 |2, carrying worm gear ||, spur gear l3 and in-.
ternal gear I9, is free to rotate either independ
ently of shaft IT' or in unison therewith, and
that shaft I1 is adapted to be propelled length
wise within its bearing and sleeve |2 while the
several parts are in motion.
.
Referring again to the left hand end of sleeve
l2, Fig. '7, also to Fig. 8, it will be noted that
the body of sleeve l2 projects beyond the bear
ing ||-—l5 su?iciently to receive, in a ?xed rela
tion, an internal spur gear l9-having charac
teristics similar to those of spur pinion l3. Gear
- I9 is so affixed as to extend somewhat beyond the
end of sleeve‘ |2 the extended portion forming a
toothed recess adapted to receive, in a slidable
manner, the pinion |9,-as' clearly shown in Figs.
7 and 8.
,
It will be clear that the combination of inter
nal gear l9, as affixed to sleeve l2 and pinion l8
as a?ixed to the slidable shaft l1, form an effec
tive clutch unit. The utility of this will be
referred to presently.
extension, all as clearly shown .in Figs. 5 and 6. 20
Consideration of Figs. 3 and '1, together with
the foregoing description, will clearly indicate
that spring 23, in addition to retaining clutch
members |8—|9 in engagement,‘ as already de
scribed, also operates, through the ?ange of 25
thimble 2|, lever 21,. screw 29 and shaft 30,‘ to
retain washer 32 against rotatable member 25.
It is also obvious that rotation of said member 25
will, due toits peculiar form already mentioned,
and the follow-up action due ‘to spring 23, im 30
part a reciprocal motion to shaft 33, which
latter is adapted, through lever 21, as already de
scribed, to impart a similar motion to shaft l1;
thus, it is clear that rotation of key 24 through
alternate half turns, will result in engagement 35
and disengagement of clutch members |3—| 9,
the whole forming a convenient manual control
of the ironing roller drive.
The ironing roller drive is utilized in the fol- '
lowing manner: Considering Figs. 6 and '1, it will
be noted that pinion I3 is, regardless of its lateral

Fig. '1, it will be noted-that a ?anged bushing 2|)
is a?ixed thereto by means of a threaded por
tion, as shown. A thimble member 2|, having an
enlarged and ?anged portion, is rotatably
mounted upon the bushing 20 and is retained
thereon in rotatable relation by the ?ange of the
bushing 20, washer 22 and lock-nut 22a, as clear
ly shown. ‘The enlarged portion of .thimble
member 2| is adapted to extend somewhat over
a boss portion ofthe frame‘ IS with su?icient
clearance to retain a compression spring 23,
which latter reacts between frame I5- and thim
~ble 2|, tending ,to‘ propel shaft 11 toward the
right, Fig. 7, and thus retain pinion l3 in en
gagement with gear l9.

rotatably mounted in bushing 35 supported by a
boss extending from housing It as best shown in 45
Fig. 7. To the opposite end of shaft, 34_ is af
fixed a spur pinion 36 which is so disposed as to
mesh with an internal gear 31 attached within
the body of ironing roller tube 33.
_
Through the wheel and hub portion of internal 50
gear 31 and a suitable ‘web and hub member in
the outer end of tube 33, not shown, ironing
roller 38 is rotatably mounted upon a tubular ex
tension 39 which latter is rigidly'supported by
an extended portion of housing l6 asbest shown
in section in Fig. 4. The roller is suitably padded
with resilient material as 330'. To prevent acci

Reference to Figs. 3 and 7 will disclose a lever
- 21 pivotally supported upon a ‘rounded extension
of housing l5 and retained thereon by a shoul
dered screw 28. Lever 21 is provided with a cir
cular opening so disposed and dimensioned as to

ternal gear 31.
Control'of the drive' is accom
plished by manual rotation of key 23 operating
through member 25, washer 32, shaft 30, screw
29, lever 21, thimble 2| and shaft II to engage or
disengage gear l8 with gear l9, as described, 70
thus controlling the linkage between the driving
and driven portions of ‘the assembly.
The ironing shoe,'suitably supported and oper-v
ated by means about to be described, is adapted
of thimble 2| already described, ‘to be placed in working contact with or removed

from the ironing roller by manual or power
means, either means being operable independent
ly of the other. Under some'working conditions, ~
the power operated means, is used, on account of
greater ease of operation. Under other condi
tions of ironing, the manual operation is con
venient or necessary._
~
The shoe unit is composed of an ironing plate
48 of sufiicient length to extend slightly beyond
the ends of the ironing roller 38 and of suitable
width to meet the requirements of manufacture
and use. The contacting surface of the plate
is so formed as to complement the peripheral
outline shown in Fig. 13 clearly indicates the
action.
When hand lever 58 is rotated. toward the
dotted line position, cam 49a is removed from
its locked position in recess 48a, permitting spring
55 to operate links 43, as described, thus with
drawing the ironing shoe as clearly outlined in
the drawings. It ‘will be noted that arm 48 re
mains‘ stationary during this operation. Return
of ‘the operating handle to its normal position 10
reestablishes original relative positioning of the
several members.

To the opposite end of shaft 41, within the
housing IS, a double arm 64 is rigidly attached
by means similar to those described in the case
of arm 48.

The foregoing description will clearly indicate‘
that the ironing shoe is supported by, and oper—

supplementary to, yet supported by, the arm 48.
Under certain conditions of use, it is some
70 times desirable to temporarily remove the iron
ing shoe from contact with the roller 38 without
disturbing the position of the major operating
members.

Considering the foregoing description, together
with the ?gures noted therein, it will be clear
that rotation of eccentric 11 will result in a re
70,
ciprocal motionin lever 88 through link 16, and
that a similar motion will be imparted to iron
ing shoe 48 through lever 69, spring 14, etc., to
arm 84, through shaft 41 to arm 48 and shoe 4!). 75

Thus, the function of eccentric ‘I1 is to apply
?xed to the disk surface level by rivets 81 as
and remove the ironing shoe to and from con
tact with the ironing roller 88. 'The resilient
shown.
mechanism, including spring", stud 88, etc..
5 are so adjusted that the angular movement of
lever 88 is somewhat greater than that of iron
his .shoe 48. The result of this adjustment is
that shoe 48 contacts with the faceof the iron
ing‘ roller somewhat before lever 89 reaches the
10 limit of its stroke to the left, as viewed in Fig. 3.
Continued rotation of eccentric 'I‘l toward the
left results in continued motion of lever 89 and‘
consequent compression of spring 18, the pres
sure induced thereby being transmitted to shoe
15 48 ‘by means already described.
Thus, the con
tact pressure between shoe and roller is ?rm
but yielding, ‘and may be adjusted by.means of
nut“ on stud 88.
_
Integral with the body of eccentric ‘I1 is a
20 disk portion 19, the whole being rotatably sup
ported by a shouldered stud 88 which is a?lxed
in the plug 8|, the latter being pressed into tube
88, all as shown in Fig. 4. The outer end of stud
80 is supported by a bracket member 92 dis
' 25
posed and attached to housing gmember It, as
best shown in Fig. 3.

,
Motion is imparted to eccentric 11 .through a
clutch ‘coupling to be described, and a spur gear
98, which latter is meshed with power driven
30 gear l8 a?'ixed to sleeve I2, as already noted and
described.
Fig. 4 will indicate that gear 94 is rotatably
supported upon stud 80, already described.
A
toothed disk member 88 is ?xedly attached to
35 gear 88 by means of a boss extension of the hub
of the latter and riveted pins, as clearly shown
in section in Fig. 4. The unit is adapted toidle
freely upon stud 88. An outline of disk 98 is
clearly shown in Fig. 5.
It has already been noted that integral with
40
the body of eccentric ‘I1 is a disk portion 18 so
disposed that.its face opposes the side face of
toothed disk 88 as clearly shown in Fig. 4. The
face of disk 19 is recessed-to several levels, the
45 level, area and form of the recesses being suitable
to receive operating members to be described.
Referring to Figs. 11 and 12, the areas desig
nated as 19c correspond to the face of disk 19,
while 19b designates a recessed area of what
50 might be called single depth with similar area
located on the opposite side, and 19a designates
an area of double depth.
Rotatably retained in recess 1901s a plate mem
ber 82 having a central circular opening, as
55
shown, also diametrically opposed projecting fin
ger members as 820 and 82b and a rigidly af
?xed stud 98, disposed as shown and projecting
outwardly from the surface of the plate 82.
Slidably retained upon vthe areas 19b is a
60 plate member 88 having a recess 9| formed in
its upper edge dimensioned and disposed to loose
ly receive stud 98, also an oblong opening dimen
sioned and disposed to clear the hub portion of
disk ‘I9, as shown. Rigidly a?lxed to the surface
65 of plate 88 is a block part 84 disposed and formed
as shown with a tooth 84a projecting toward the
center and extending outwardly from the sur
face of the plate.
-

It will be clear that fractional rotation of
plate 82 with relation to the body of disk 19,
will result in a corresponding reciprocal motion
of plate 88 through stud “operating in recess
9|. Rotation of plate 82 beyond predetermined
limits is prevented by shoulders formed by the I
raised areas ‘He.
The relative positions of disk. ‘I8 and toothed 10
disk 98,,as assembled upon stud 88 has already
been noted. Considering the-foregoing descrip
tion, it will be clear that with the parts as
sembled as described, the toothed block 88, pro
jecting beyond the surface of plate 88 and disk 15
19, will also project over toothed disk 98 as shown
in Fig. 4. A plan view of the several parts is
clearly shown in Fig. 5, also a broken section of
toothed disk 98 is outlined in Figs. 11 and 12.
’ It has already been noted in connection with
Figs. 5 and 7, that a spur gear I8 is ?xedly‘
mounted upon the power driven sleeve l2. The
view shown in Fig. 5 illustrates that gear l8 runs
in mesh with gear 94, thereby gear 94, together
with toothed disk 98 is maintained in rotation
by the power source.
Considering the foregoing, in connection with
Fig. 11, it will be obvious that rotation of plate
82, with relation to disk member v‘l9 will, by
means already described, result in movement of 30
tooth 88a toward center and into engagement
with toothed disk 98. Assuming that disk 98 is
in rotation when ‘said engagement takes place,
it is clear that eccentric 'I'I will be set in motion
through members already described.
Still referring to 0Fig. 11, it will be noted that
tooth 84a is normally retained in engagement
with disk 98 by the action of a spring 88 at
tached to plate 82 by means of a stud 89 and to
disk 19 by one of the rivets 81, as clearly shown. 40
Assuming disk” to be in rotation in direction
shown by the ‘arrow and the parts positioned as
shown in Fig. 11, it is obvious that disk ‘I9 will
be rotated through engagement between disk 98
and tooth 88a,'until ?nger 82a meets an obstruc 45
tion such as stop 98. Continued rotation of the
unit, with rotation of plate 82 arrested by stop
98, will displace the parts as shown in Fig. 12,
wherein plate 88 has been displaced toward the
right by means already shown and described and
tooth‘8la has been withdrawn from engagement
with disk 98. With the parts positioned as shown
in Fig. 12, it is clear that, while disk 98 continues
to rotate, disk 19 will remain‘ stationary until
stop 98 is removed to a non-obstructive position. 55
When such removal takes place, spring 88 will
restore parts to the relative positions shown in -
Fig. 11. It is considered obvious that if, after
each escapement of ?ngers 82a‘or' 82b, stop 95
is restored to the obstructive position, rotation
cannot continue beyond one hundred and eighty
‘degrees without further manipulation of the stop.
Bearing in mind that eccentric ‘I1 is integral

parts to place the ironing, shoe in contact with
the roller through means alreadyv described.
It will be apparent that a further momentary
removal of the stop’ 95 will result in rotation of
eccentric ‘I ‘I through another half revolution or to
a position diametrically opposite that shown in
Fig. 3, causing the ironing shoe to return to con
tact with'the ironing roller.

' Manual control, of the above described clutch
10 unit is effected through operation of the stop
95 as already noted. Reference to Fig. 4 will show
that stop 95 is fixedly attached to a shaft 96
which is rotatably mounted in suitable bearings
and disposed at right angles to stud‘ 80. Shaft
15 96 passes through the wall of housing I6 and
terminates in a knob 91 ‘by which the .shaft is,
conveniently rotated as desired.
Rotation of shaft 96 is limited by extensions
98 and 99 which are integral with the body of
20 stop 95 and provided with resilient facings as
I00 and MI.

A ‘coil spring I02 suitably attached to shaft 96
and body of housing I6 tends to rotate said shaft
96 in a clockwise direction, as viewed in Fig. 4,
25 thus maintaining extension 99 in contact with
housing I6 and stop 95 in position to obstruct
?ngers 820. or 82b.
It is obvious that slight manual rotation of
knob 91 in counterclockwise direction will result
30 in similar movement of stop 95 out of line of ob
struction to teeth‘ 82a. and 82b, thus permitting
operation of the clutch unit as already described,
Practical manipulation of the knob would con
sist of a slight rotation counter-clockwise, and
35 release. This manipulation would obviously re
move stop 95 out of line of tooth 62a or 82b, al
lowing same to escape. Release of the knob
would result in restoration of stop 95 to its origi
nal position, ready to obstruct the next approach

tion of the knob 91 would result 'in a half revo

of link ‘I6 as shown in Figs. 3 and 9. Plunger
I04, shown in section in Fig. 9, is normally held
in an out-stroke position by a spring I06, and
is adapted to'be forced downwardly'and in by
the lower edge of link ‘I6 as the latter moves
through the lower swing of its cycle. As clearly
shown in Figs. ,3 and 9, pumping movement is
imparted to plunger I04 by the alternate action
of spring I06 and cam-like action of' link '10‘. 10
Oil is taken in'through an ori?ce I01, checked by
a ball I08,'forced through check I09, through
tube .I I0 and ejected therefrom so as to fall upon

I6, where it returns for recirculation after ?ow
ing over the mechanism.
From the foregoing description, it will be clear
that ample lubrication is provided as a conse
quence of the frequent operation of the ironing‘ 20
shoe unit.
It is well known that ironing machines of the
class described are used for ironing a great va- _
riety of materials and garments. Obviously, to
explain the operation of the machine with ref 25
erence to each material or garment would in
volve almost endless detail.
' It is thought that operation of the several parts
and groups composing this ironer have already
been described with su?icient detail to obviate 30
the need for any but summary description herein.
It will be noted that the ironer has several
distinct means of manipulation, ?rst the individ
ual control of rotation of the ironing roller by
means brought into operation by manipulation
of the key 24, second, individual operation of the
ironing shoe by manipulation of the hand lever
50 and, third, control of power operation of the ‘
ironing shoe and roller by manipulation of the
knob 91.

The combination of the three operating fea
tures mentioned obviously adapts the machine to
a wide variety of uses, which may be summarized

ed lip portion ‘I8 as integral with link ‘I6. Re
ferring to Fig. 16, it will be noted that the said the ironing shoe in non-working position, the
lip is so disposed upon link ‘I6 that when the , operator places material to be ironed upon the
link passes through the upper swing of its cycle, ironing roller in such a position that the entering
edge of the material will be under the ironing 50
the lip 18 contacts with a shoulder formed in the
‘ body of lever 21, as clearly shown in Fig. 16. The , shoe when the shoe is brought into contact with‘
result of this contact is a displacement of lever
the roller. , A slight turn of the knob 91 will cause '
21 to disengage the roller operating clutch by
the shoe to move forward into contact with the
roller and material, following which a half turn of
key 24 will set the roller in motion. Thus, the 55
material will be inducted under the ironing shoe
I means already described.
The movement of lever 21 is identical with that
produced by manipulation of the key 24, already
described. Since the ironing shoe is thrown out
of contact by the upper swing cycle of link ‘I6,
it follows that whenever the ironing shoe is, by
60 power, thrown out of contact, rotation of the
'
ironing roller is automatically stopped.
\
Obviously, when the ironing shoe is reapplied as
a result of a succeeding manipulation of the knob
91, the accompanying lower and backward swing
of link ‘I6 will result in Withdrawal oi.’v the lip
‘I8 from contact with lever 21, allowing gears
I8-I9 to reengage and resume rotation of the
ironing roller. Thus, rotation of the ironing roll
er is automatically started and stopped as the
ironing shoe is applied or withdrawn by the
power means.

, It might be noted here that in the above case,
if key 24 had been in running position. the iron
ing roller would have started rotation simultane

ously with inward movement of the ironing shoe
by means previously described.
'
With the roller in motion and the shoe in con
tact, materials of ordinary thickness may be con
tinuously fed over the roller and under the shoe. 65
When ironing certain thick materials, such as
folded blankets, which might not easily enter
under the shoe, it may be desired to stop the
roller temporarily, which is accomplished by
rotating key 24 one half turn. Inorder to prop 70
erly adjust materials under the ironing shoe, the
shoe may be temporarily raised by operation of
hand lever 50 asdescribed. When the material
is adjusted, the shoe may be replaced by return
of the hand lever to its original position, after 75
