IRONER Filed oct 9, 1929 5 Sheets-Sheet Patented June'zs, 1932 UNITED STATES PATENT OFFICE LUTHER RINGER, OF UNION SPRINGS, NEW YORK, ASSIGNOR- TO SYRAC'USE WASHING MACHINE CORPORATION, OF SYRACUSE, NEW YORK, A CORPORATION OF DELA- WARE IRONER Application led October 9, 1929. Serial No. 398,386.

This invention relates to a new and improved ironer.

My invention is particularly directed to a means for supporting the ironlng shoe which a is moved into and out of contact with the roll and the'shoey and remove the ironing roll.

In ironers of the type here described, the shoe is intermittentl moved into andout o contact with the roll to permit the insertion therebetween of the goods to be ironed and then to perform the ironing operation.

It is usual in ironers of this type to provide a means such as an electrical resistance coil for heating the ironing shoe and when this is the case, the clothes being ironed should not be allowed to remain in contact with the heated shoe any longer than is necessary to perform the ironing operation for otherwise there is danger of scorching or burning the clothes.

In order that' the shoe may be manually moved out of contact with the roll in order to permit the removal of any clothes which -3 may be between them, it is desirable that the shoe be so connected to the operating mechanism that such manual control is permitted. For example, if through the burning out of a fuse or any other cause, the operation of the ironing machine should be stopped at a time when a piece of material was under pressure4 between `the roll and the heated shoe, itis essential that some means be provided so thatthe operator may separate the p l goods before they are damaged. f

Also, occasionally goods may be started between the roll `and theshoe in thewron vdi'- rectionl or in a creased y' condition and 1t is then desirable to provide a convenient means whereby s uch clothesma'ybelreleased and started overfagain in'v thelproper shape.'` `-The main object of my invention is to provide a supporting means for'the 'shoeof an ironing machine which normally will perfmit the shoe to be automaticallymoved towards land from the`^ roll duringthe operation lof the machine but which is so designed thatl the' `shoe fmay 'be manually disconnecte'ed A from its driving Kmea'ns"andvfbemovedw'out hold 1'9*l tofalordfan-easymeansfofreturning and automaticallyof contact with the roll irrespective of the continuing operation of the mechanism of the ironing machine.

Another object is to provide a support for a shoe which is of such a design that when the shoe has been manually disconnected size, shape and arrangement of parts all as will more fully appear from the following description taken in connection with the accompanying drawings in which Figure 1 is a top plan view partially broken away of my improved ironing machine.

The ironing machine 1 comprises a gear casin 2 with av roll 12 extending laterally there rom and* with 'a shoe 11'in parallel relationwith roll 12 and operatively connected to a shaft 5 which, extends `laterally from the gear casin'g2;` t i Shaft 5 is'journaled ina tubularbearing 6 which hason'e end extending intol gearcasing2-and which has the outer end supported in a saddle?. vOn 'the outer end' of shaftl 5 is rotatably mounted a yoke 8. On'the .upper y vend of yoke 8 Ais` pivotallymounteda oe s support l9. to the forward end of which and "above the pivot'lO is secured the shoe 11.

Shoe support 9 is provided v'witha fhand A through shaft 5 will be transmitted to yoke 8.

Within shoe 11, I provide a dotted lines .on Figure 3. After this initial heating resistance unit 14, connected, as by a movement has been completed, shaft 31 may cable 15,to a source of potential not shown. be moved still further in the same direction A spring 16 has its upper end secured to causing yoke 8 to pivot about shaft 5 to move the rear face of shoe 11 and has its lower end shoe 11 out of engagement with roll 12. The bearing against the inner face of yoke 8 to position of parts after this second movement hold shoe 11 in the raised position when the of shaft 31 has been accomplished is indicated same is out of contact with roll 12. i in heavy dotted lines on Figure 3.

Between the sides of yoke 8 and pinned to For the urpose of limiting this latter shaft 5 as by a pin 17, I provide a'member movement 0I yoke 8, I provide on yoke 8, a 18 which has its outer end provided with an pin 35 lwhich is adapted to Contact with a linaperture 19 through which extends a rod 20. ger 36 provided on saddle 7.

The lower end of rod 2O is provided with With the parts in the last described posia transverse pin 21 normally abutting a tion, it will be noted that the hook 27 is curved guide 22 on member 18. 4 beneath 'but in the path of movement of the The upper end of rod 20 is provided with pin 21 when the same is moved downwardly an adjusting nut 23. A spiral spring 24 has due to the rotary movement of member 18 lone end abutting nut 23 and has its -lower end on shaft 5 so that when such movement of abutting member 18 to normally urge rod 20 member 18 subsequently takes place through inthe raised position with pin 21 abutting the operation of the mechanism about to be guide 22. described, pin 21 will ride downwardly past On the vlower end of yoke 8 is pivotally hook 27 due to the fact that it will cause the mounted as by a pivot 25, a dog 26 which pivotal movement of dog 26 against the action carries on its upper end a hooked portion 27 of spring 28, and after pin 21 has moved adapted to normally enga e the pin 21 to downwardly beneath hook 27, spring 28 will lock the yoke 8 to the mem er 18. cause dog 26 to move about its pivot to bring A spring 28 has one end secured to memberefhook 27 into registration with pin 21 so that 18 with the other end secured toV dog 26 to rethe parts will become locked in the initially leasably hold hook 27 in registration with described operative position and any further pin 21. With the parts in the normal posimovement of member 18 will cause yoke 8 tion, any movement transmitted to member 18 and shoe 11 .to be moved with it as a unit.

The mechanismvprovided for operatin the On the upper end of yoke 8 is pivotally roll 12 and the shaft 5 comprises a sha 37 mountedas by a pivot pin 29, a bell crank 30. journaled in gear casing 2 and having mountthe upper end of bell crank 30, I provide ed thereon a worm gear 38 which isv in mesh a vertically extending shaft 31 carrying aV with a worm 39 carried on the armature shaft knob 32, at its upper end. -The other arm 32 of a motor 40 which motor 40 is, for convenof bell crank 30 is in en agement with a rod ience and compactness, mounted in vertical 33 slidably mounted in t e upper end of yoke position on gear casing 2.

8 and having its lowerend pivotally mounted On shaftl 37 is rotatably mounted a cam 1n the outer end of 4dog 26. member 41 which is positioned in the open The lower end of bell crank 30 has a stop end of a jaw arm 42 which is secured to the 34 which abuts the yoke 8 to limit the moveinner end of shaft 5, as by a piny 42. ment of bell crank 3() in one direction. V On the side of cam member 41 which faces With the arts 1n the position just deworm gear 38 is pivotally mounted a clutch scr1bed,'mem er 18, yoke 8 and shoe 11 will dog 43 as by a pivot pin 44. On the hub 45 be actuated as a unlt through the movement of worm gear 38 is secured as 'by a pin 46, -of shaft 5 which movement will be hereina clutch member 47 provided on its periphery after described but which is adapted to move with spaced recesses 48 adapted to receive` a shoe 11 towards and from roll 12. finger 49 carried on dog 43.

When itis desired to release yoke-8 from A spring 50 has one end secured to cam 41 member 18 so that .yoke 8 carrying shoe 11 as by a pin 51 and has its other end secured may be moved about shaft 5 toA move shoe 11 to dog 43 to normally move dog 43 about its out of engagement with roll 12, the bell crank pivot to bring finger 49 in registration with 30 1s moved about its pivot by means of shaft a recess 48. 31 and this movement will cause the end 32 When dogI 43 on cam 41 is in registration of bell crank 30 to move downwardly pushing with clutch member 47, the cam 41 will be before 1t rod 33. f operatively connected to the worm gear 38 so The downward movement of rod 33 will that the rotation of such gear 38 will cause cause dog 26 to be moved about its pivot 25' the rotation of cam 41.

The rotation of cam 41 will in turn cause an oscillating movement of jaw arm 42 which oscillating movement will be communicated to shaft 5.

For the purpose of holding dog 43 out of registration with clutch member 47 sothat cam 41 will be at rest, I provide an arm 52 secured to one end of a shaft 53 which is pivotally mounted in gear casing'2.

In the normal position, the arm 52 is in the path of movement of dog 43 so that the latter is held out of contact with the clutch member 47. i

The arm 52 is normally held in-this last described position by means of a spring 54. On the outer end of shaft 53, I provide an operating handle 55 by means of which shaft 53 may be rotated a limited distance to move arm 52 out of the path of movement of dog 43 to permit the same to be brought into operative contact with clutch member 47 through the operation of spring 50.

The dog 43 has its opposite ends extending outwardly so that they will alternately come into contact with arm 52 so that if arm, 52 is moved out of contact with the end of dog 43 with which it was in engagement, the cam 41 will begin to rotate andwill continue to rotate until the opposite end of dog 43 comes into registration with arm 52, the latter meanwhile having been allowed to return to the normal position by the releasing of operating handle 55.

It will thus'be seen that the rotation of cam 41 will be stopped after it has completed onehalf of a revolution. i

Adjacent the rear face of worm gear 38 and rotatably mounted on shaft 37, I provide a gear 56 having the side which is adjacent gear 38 provided with clutch teeth 57 adapted vas to engage the clutch teeth 58 provided in the face of gear 38.

Gear 56 is held between collars 59 and 59 which are secured to shaft 37, and shaft 37 has a spring 58 normally urging it in a direction to cause clutch teeth 57 to engage clutch teeth-58. A description of the opera-A tion of the specific clutch comprising mem- `,bers 57 and 58 is not essential to the description and explanation of my invention here l disclosed. It is sufficient to state that the clutch teeth 57 and 58 are normally in engagement during the operation of the machine so that roll 12 will be rotated through gear 56 which is in mesh with a gear 60 journaled in gear casing 2, whichgear 60 is in turn driven by suitable gearing not shown. Such specific clutch and operating mechanism therefor is disclosed and claimed by me in my copendingy application on an ironer filed N0- vember 29, 1929, Serial No. 410,484.

For the purpose of providing a convenient means for controlling the heating unit 14 in shoe 11, I provide on gear casing 2, a switch 61 in the electrical circuit.

Operation When it is desired to use my improved ironer, the motor 4() is connected in any conto send electrical current to the resistance 14 in shoe 11. l

A switch not shown is then turned to the on position causing the motor to rotate worm gear 39 and this, through gear 38, gear 56, gear 60 and an internal gear not shown on roll 12 will cause the rotation of roll 12. The clutch dog 43, not'being operatively connected to the clutchmember 47, will not cause rotation of the cam 41 and therefore the shaft 5 will remain at rest.

In order that an article may be passed between the roll 12 and shoe 11 for the purpose of ironing the same, it is necessary to turn the handle 55 which will move the member 52 from the path of the dog 43 to permit .at the same time, the shoe 11 will be moved towards roll 12 and will be temporarily held there under a predetermined pressure, the continuing rotation of roll 12 carrying the article downwardly and beyond shoe 11.

- The movement of shoell towards and from roll 12 is intermittent due to the fact that when the dog 43 has been released from the member 52, it will again engage such member 52 after one-half of al revolution of the cam 41 to withdraw dog 43 from clutch member 47,k and interrupt the movement of cam 41.

With the parts in position shown in Figure 2 withithe high side of cam 41 against the lower arm of jaw member 42, the shaft 5 will have been rotated to the greatest extent in an anti-clockwise direction and the shoe 11 will be held, firmly against the roll 12 as indicated in Figures 3 and 4. When by the manipulation of handle 55, the dog 43 is permitted to engage clutch member 47 the cam 41 will make a one-half revolution which will bring the high side of such cam 41 in registration With the upper part of jaw member 42. In this position, the shaft 5 will have lbeen rotated the greatest distancein a clock- `11 and roll 12. This operation may be repeated as often as desired.

To illustrate the operation of the manual release of shoe 11 and the automatic return of the same, I will assume that the apparatus has been stopped with the parts in the position shown in Figures 2, 3 and 4, at which time, the shoe 11 is in pressure contact with roll 12, and that the electrical circuit running to the machine has been broken so that cam 41 cannot be caused toV rotate by the manipulation of handle 55.

If, under these circumstances, an article is positioned between shoe 11 and roll 12, it would become scorched or burned if left in that position due to the fact that shoe 11 has been heated by resistance 14.

VIn order to remove such article,'the shaft 31 is manipulated in the manner heretofore described to move the parts from the position shown in heavy lines on Figure 3 to the position shown in heavy dotted lines on Fi ure 3 in which position the shoe 11 is 1n spaced relation to the roll 12.

If, with the parts in this last described relation, the electrical circuit is again completed, handle 55 may be vmanipulated to cause one-half of a revolution of cam 41 to bring the high side thereof into contact with the upper arm of fork member 42 which will cause the rotation of shaft 5 in clockwise direction. This rotation of shaft 5 will carry the outer end of member 18 downwardlyto cause pin 21 to pass beyond hook 27 on dog 26, and pin 21 will then engage hook 27 to lock yoke 8 to member 18. 1

If handle 55 Ais then again manipulated, cam 41 will be caused to rotate to bring its high side in registration with the lower arm of jaw member 42 and this will cause the rotation of shaft 5 in an anti-clockwise direction, and this rotation of shaft -5 will cause the outer end of member 18 to be carried upwardly moving with it yoke 8 and shoe 11, and shoe 11 will be brought again into contact with roll 12.

The shoe 11 has beenv d scribed as being held against roll 12 unde pressure which is true, but the pressure exerted by shoe 11 aginst roll 12 depends upon the tension w 'ch is given to spring 24 by the manipulation of nut 23 so that if the resistance offered by the articles passing between shoe 11 and roll 12 is greater than the strength of spring 24, spring 24 will flex to permit shoe 11 to move slightly away frpm roll 12.

The flexure of spring 24 under these circumstances is permitted because shoe 11 is carried on yoke 8 and yoke 8 is connected to member 18 by a hook 27 which is in registration with a pin 21 positioned in the lower end of rod 20, rod 20 being held in the ralsed position by the spring 24.

IfA the pressure exerted against shoe 11 and through yoke 8 and hook 27 to pin 21 is greater than the strength of spring 24, the rod 20 will be pulled downwardly which will ermit the yoke 8 to move slightly about s aft 5 and this will cause the movement of shoe 11 from roll 12.

The provision of spring 24 and adjustable nut 23 permits a variation in the pressure exerted by shoe 11 against roll 12 so that the amount of such pressure may be changed -from time to time as desired to insure that the minimum necessary pressure is always exerted by shoe 11 on roll 12.

Although I have here shown my improved shoe support as being used with a particular type of ironing machlne, it will be understood that it is well adapted to be used with different types of ironing machines.

It will also be understood that the various sizes, shapes and arrangement of parts of sizes, shapes and designs of ironing machines,
