Application led May pressure of av launderingJmember against a f roll, with which the laundering member co-v operates forlaundering, is operative-by reaction after "the initial operation of the laundering member. g

A st'll further object ofl my invention is Y to provide a. laundering machine in which the exertion. of fa smallamount of forcelbyl an operator is augmented by -power mechanism to produce great pressure between two l laundering members which cooperate for 25. laundering purposes.' i j A still further object of my invention is to provideA a simple and inexpensive -p'ower mechanism .forvmoving a laundering member into operative relation with a second laun; dering member for direct laundering action -fonarticles to be laundered.

Vand is apertured to receive the bent/end of :a link 16 -whichextends through an opening 65 in a leverV 17 which supports the trunnion 18 ofthe shoe 2. The other endof the sh'oef 2 is pivot'edon 1a.. lever 19 similar to the lever 17.' -The levers 17 and 19 are rigid with a` rock shal`tf244 journaled in stand- On one side of the leverv 17, a shoe-,coms .i

at one end, acollar 23 on the link 16.l An additional lever 25 is secured to the rock shaft 24 and carries, at its upper'end, 80 a pin 26 o'n -which a sprocket wheel 27 is Q mounted for rotation and from which depends an armv 28 rigid'with the casing 30 of a reduction mechanism not shown). iven by the motor 3 and transmits power to a sprocket wheel 31 mounted on the casing. AA chain sprocket wwheels 31, 27

and 8.

In the operation of the device, when it is 90' and the control handle 1 4 is swung forward-4 position shown in Figs. 1, -3 and 4. Moveiment of the control` handle 14 operates to vmove t e lever 17 and vshoe 2 and establishes ontact between the ,shoe 'l 100 a. light pressure c 2 and the roll 1. y

The movement of the control handle 14 alsooperates to move'the arm 1,5 ofthe bell crank rearwardlyfand to thus throw the clutch vcollar 11`inwardly, the pl-ungers 10 movesA the et Awheels 27 posed upon the endless chain 32, the tensioning of which results in a tendency for sprocket wheel 27 to move toward sprocket wheel 8. This tendency to movementexerts a force upon the lever 25, the shaft 24 and the ,levers 17 and 19. After the building up of pressure between the shoe 2 and the roll 1 to a point corresponding to normal operating conditions, the chain 32 operates to rotate the roll 1.

The spring 20 exerts force on lever 17 which is transmitted to the shoe2 and produces shoe pressure on the roll 1. This pressure tends to oppose rotation of the roll 1 and, therefore, requires greater tension in the endless chain 32 to produce rotation in the roll 1. The increase in the tensioning of the chain 32 operates to exert greater force on sprocket wheel 27, tending to urge the sprocket wheel 27, the lever 25the levers l17 and .19 and Ithe shoe 2 toward the roll 1. It is apparent, therefore, that, when the operator moves control handle 14 and compresses spring 20 manually, the force which he exerclses is greatly augmented by the motor 3, and great pressure is produced by the shoe 2 on theroll 1. In thisoperation, a principle of reaction is utilized. The reaction to the force required to rotate the roll 1 is directed to producing pressure b the shoe 2 on the roll 1. This ensures su cient pressure for good ironing.

, When it is desired to. move the shoe 2 away from the roll 1, the control handle 14 is moved by the operator from the position shown in Figs. 1 and 3 to the position shown in Fig.' 2. The movement of the handle 14 releases thev pressure of the spring 2O on the lever 17 which reduces to a certain extent the pressure of the shoe upon the roll, whereby the force r uired to operate the r'oll is a-ppreciably re uced and the levers 25, 17 and 19 tend to'move to the left of the position shown in` Fig. 1. The tendency of the levers to move to the left further reduces the pressure of the shoe upon the roll, and

- since this tendency is cumulative, the levers finally assume the position shown-in Fig. 2. The levers are normally biased to this position bythe weight of the motor and gearing suspended from lever 25, so that upon the decrease in-tension of the chai 32, a move- 'ment of the levers to the left sults. The

vhandle 1 4 mav be urged further rearwardly to compress the spring 22 on link 16, thereby urging lever 17 and shoe 2 away from the roll, in the event that the material being ylevers 17 and 19 to the left to eect the disengagement of the shoe and roll. After the shoe 2 has been moved away, the arm 15 of the bell crank is. free to move forwardly since the' link 1G has passed beyond the point of pivotal connection of the control handle 16 with the. arm 15 of the bell crank. The continued urging rearwardly of the control handle 14 operates to shift the bell crank and throw'thc clutch out, the plungers 10 being retracted from engagement with the pin 9.

The roll is then free to rotate. either forwardly or' rearwardly. This facilitates the arrangement of garments for ironing and, in cases where articles have become wound about the roll 1, it permits the reversing of the roll for removal of the articles.

Since the greater portion of articles vironed are thin, the differences o f thickness are unimportant and do not interfere with the operation of anv ironing machine inthe manner described. l

It will be apparent that the principles of the invention are of general application and may be used for establishing pressure between the cooperating elements in lnangles, ironing machines and laundering appliances in general.

Any ydrive functioning by reaction after the manner of chain 32 or any mechanism which, inits functioning to drive the roll, sets up a pressure or forceful reaction, may be used. The clutch shown and described, while a useful accessory to satisfactory manipulation of the machine as Van-ironer, isv

not functionally essential to utilization of the principle of utilizing the reactive force set up.

The invention is not limited to details of construction, but the embodiment shown and described may be extensively modified and varied `without 'departing from the spirit of the invention and the scope of the ap pended claims. A substantial range of equivalents is contemplated.

I claim as myinvention:

1. In'an ironing machine, the combination of a shoe, a rotary roll, means for manually moving the shoe to and from the roll, a motor for operating the roll, and means operable by said motor for pressing said shoe against said roll, said means-being operative.

by a reaction to the operating force whichl rotates said roll.

2. In a laundering machine, the combina tion of a laundering member, a second laundering member adapted to cooperate with the first-mentioned laundering member for direct action upon articles to be laundered, means for effecting the application of force by .an operator for pressing said first mentioned laundering member against' said second laundering member and means operative by the contact of said first-mentioned laundering member with said second laun fdering member for automatically building' up an ironing pressure between the launderlng members. v

3. In'a laundermg m'aclnne, the combina tion of a laundering member, a second laundering member adapted to vcooperate with 'the first mentioned laundering member lfor directl action upon articles to-be laundered,

a control member,l a resilient connection be-' tween sal-d control member and said irst mentioned laundering member vfor moving said first mentionedl laundering member into contact with said second laundering member land means for moving said second laundering memberafter Contact is established, said rotating said (roll, a secondlaundering .member ,adapted to cooperate `with said roll \for ironing, a second sprocket wheel supported for rotaryl movement. with respect to said second laundering member and adapted to move therewith and a motor-driven chain ex` ;tending over said sprocket wheels for rotating said `roll and for pressing said second launderingfmember against said roll,i when`v 30,' an initial braking force is applied to the. Y,

roll, thereby increasing` the tension in the chain a'nd moving the second sprocket wheel and the associated laundering member:

against the roll.

'5. In 'a laundering machine, the combination of a roll, a laundering member adapted to 'cooperate with said roll for direct action upon articles to lbe laundered, a lever arml supporting said ironing member, a .second lever arm operative therewith, a sprocket wheel on said second arm, a chain extendingover said sprocket wheel, means for moving the laundering member to the roll, and drive means on said second lever arm for them moving said chain and rotating said roll therewith', said drive means being operative through the tension in s aid chain to main'- tain said ironing member against said roll. l
