In ironing machines it has been customary heretofore to have a plurality of rollers, certain of which were heated, or to have a vcool roller with a heated ironing shoe, whereby the rollers or shoe were either permanently positioned relative to each other, or manual means were supplied to move either the rollers or the shoe.

This invention relates to ironing machines of the type in which the heat is furnished to the ironing shoe which isA located in operative relation to the ironing roller.

The present invention has for its primary object to provide improved and automatic 16 means for moving the ironing shoe towards or away from the ironing roller.

Another object is to provide novel and improved means for operating the ironing machine.

Another object is to provide new and novel clutch mechanism for stopping and starting the machine and which will automatically control the movement of the ironing shoe.

A further object is toprovide a tilting board arranged adjacent the ironing roller for controlling the, operation of the automatic means for moving the ironing shoe.

And another object is to provide an ironi ing machine which is simple and eicient in operation, which can be readily and economically manufactured, and which can be adjusted vertically on its frame work tok suit varying conditions. y

Fig. 7 is a rear elevation. Fig. Sis a detail front elevation.

Fig. 9 is a plan view of the throwout disk. Fig. 10 is a detail elevational View with parts broken away'showing a portion of the 55 device disclosed in Fig. 1 in another operative position. C

Referring to the drawings 1 designates a suitable frame upon which a support 2 is integrall attached for Asupporting a motor 3. 0.0 A worm 5 suitably supported in the frame 1 receives its power through the flexible connection 4 connected to the motor shaft. The worm wheel 6 mounted on a .stub shaft 7 meshes with the worm 5. A spur gear 8 05 is integrally connected with the worm wheel -6 and receives its motion therefrom.

The spur gear 8 is provided with clutch teeth 9 which are adapted to be engaged with the clutch member 10 arranged on the flat 79 portion 11 of the shaft 7. A disk 12 is fxedly secured tothe outer end of the shaft 7 and adapted to rotate therewith for a purpose to be later described.

A longitudinal shaft 13 extending entirely 75 across the machine has a spur gear 14 loosely mounted thereon which meshes with the spur gear 8 and is adapted to be revolved thereby. This spur gear 14 has teeth 15, formed on the outerl edge thereof which are adapted to be engaged by a clutch 16 arranged on. the flat portion 17 of the shaft 13. A spring 18 surrounds the shaft 13 at the outer end thereof to normally cause the clutch 16 to be engaged with the teeth 15 on 85 the spur gear 14. A suitable colla-r 19 is ar ranged on the` end of the shaft and holds the. spring 18 in n'orinal position on the shaft 13.

A pivot shaft 20 suitably mounted in the 90 casing 21 of the frame carries shifting yokes v22 and 23. The upper shifting yoke 22 is looselymounted on the pivotshaft 20 and isadapted to operate the clutch 16,`whi`le the lower shifting yoke 23 is fixed to the 95 p-ivot shaft 20 and is adapted to move there-l with to operate the clutch member 10. Each 'of these yokes is provided with yoke pins 24 which engage the respective clutches to move the same in and out. A spring 25 has :100

the upper' end l thereof connected to a lug 26 formed on-the casing- 21 and the lower end connected to a lug 27 integrally formed on the yoke 23, and its purpose is to keep the 5: clutch member10 normally out ofengageinside of the disk 12. The lower yoke 23 has'.

ment with the teeth 9 on the .spur gear 8.

' The upper yoke 22 has a button 28 fixed to the 4lower: endqthereof which is adapted to be engaged by the lbutton 29 attached on the a. button 30 Whichis adapted to engage one of the recesses 31 and 32 in the disk 12. Y

In Fig. 4 the button 29'is not in contact with the button 28 on the top yoke and therefore the clutch 16 is in engagement with the spur gear 14, being held there by a spring 18 acting on the clutch 16. In Fig.` 5, through rotation of the disk 12, the button 29 is in contact ,with the button v28 and therefore the clutch 16 is out of engagement'with the spur gear 14. When the buttons 28 and 29 are in contact with each other, the button 30 on the yoke 23 engages one of the recesses in the disk 12 as shown in Fig. 5. When the disk 12 is 5 in the position shown-in Fig. 4 the button 30 may engage the recess 31 due to the action of the spring on the yoke 23 normally holding the clutch out of engagement.

Suitable Hanged supporting journals 33 arer fixed to the main shaft 1,3 at intervals and arev adapted to receive the sheet metal casing 34' 3 assuming that the motor is running, the

worm gear 5 will revolve the worm gear 6 and"v the spur gear 8 vwhich are mounted vloosely onv the shaft 7 and these in turn will revolve the spur gear 14 mounted loosely on the shaft 13, the balance ofthe mechanism will remain idle. When itis desired to operate the machine pressure is applied on'the outer edge of the tilting board 36 which will raise the inner edge thereof and cause vthe link `39 to move upwardly and, through the connectioi141, rotate the'shaft 20 in a small Y arc. The yoke 23 being fixed -to the shaft 20 will move with this shaft and cause the pin to leave its recessin the disk 12 and throw` the clutch 10 into engagement with the teeth onthe spur gear locking the same together. In this position the gears 6 and 8, stub shaft 7, clutch 10 and disk 12 are rotating in unison being directly driven by the Worm 5.

After the' disk l12 has Inoved180 degrees, the button 30 which has been in contact with the ridge 32 will drop into the recess 31,

VFig. 4, therebythrowing the clutch 10 out of engagement with the teeth 9 on thegspur gear n p y i '8. When the diskhas moved through `a small arc the button 29 will be moved away from the button 28 and permit the clutch 15 to engage the teeth 16 on the gear .14 for driving the main shaft 13' and the ironing roll 35.

' When it is desired to stop the machine pressureis again applied tothe outer edge of the tilting board which again causes the shaft I 2O to rotate in a small arc, throwing the .clutch member 10 in`engagement thus rotating the stub shaft 7 which, in turn, rotates the disk 12 until the button 29 contacts with the button 28 to throw the clutch 15 out of engagement with vthe gear14, thereby causing the shaft 13' and roller 35 to becomestatio'n-v ary. Simultaneously with the contact of these two buttons 28, 29, the button 30 will engage the recess 32 on the disk 12 and cause disengagement of the clutch 10 from the teeth on the spur gear 8. The vparts willthen be in the position shown in Fig. 5. y

A crank 43 isfixed to the stub shaft 7 and drives al crank arm 44 which is `pivoted to a pin 45. Toggle arms 46 and `47 are pivoted at oneend thereof to the pin and have their other ends fixed to a rod 48 whichv is free to pivotV in the frame.

`An arm 49 interposed'between the bifur-VZ cated end 50 of the toggle arm 47 is slidably mounted in a block 51.which is pinned be-- v.

tween the bfurcated arm 52 pivoted onl thev cross rod 53. The arm 49 is threaded near its upper end to receive a Wing nut 54. Av

spring 55 is arranged'between the wing nut and the block to form a iexibleconnection v for driving .the arm '52. A stop cllar 55 is arranged on the outer end lof the arm 49 to keep the same from sliding out of the block and for the purpose of returning the arm 52 to operating position. This arrangement of parts causes a' reciprocatory movement of the arm 52.

`Another a 56 is pivoted at its lower -end to the rod` 53 and pivotally connected at its upper end to a lug 54 on the ironing shoe`57. This latter arm extends between the forked endsV 58. of the arm 52. Each of these arms is slotted as at 5,9 to receive a key 60 which l is pivoted to a cross shaft 61 passing through bosses cast integral with the arm 56. A spring 62 has one end fastened `to the tail piece 63 of the key and the other end fastened to the arm at 64.` The Iurpose of this spring is, to| holdthe key wit in the slots. l

From the mechanism just explained pressure'on the tilting 'board 36 will cause rota.

tion of the stud shaft 7 and through the` toggle mechanism cause'the ironing shoe 57 to be automaticallymoved against or away from the ironing rollerdepending-upon the position of the disc 12 and the'clutches 10 and 16. v,

' In case of emergency it maybe nove the ironingjshoe away from the roller desirable to i l by hand so a rod 65 fastened to the ironing shoe and the key may be' provided. By moving the rod outward the key is released from the slots 59 and the shoe is free to move away from the roller without interfering in any way with any of the toggle mechanism. This arrangement also permits the toggle mechanism to operate without affecting the shoe should pressure-be accidently applied to the tilting board or should some of the. parts j amb or otherwise not function. When the rod is moved forward the key again engages the slots and parts are again in position to be operated by the toggle mechanism.

A suitable handle or ball 66 may be fixed to the rod for actuating the same.

The ironing shoe is hollow and contains suitable heating means (not shown) required for heating the ironing shoe. This heating means is supplied to the ironing shoe by means of a line 67 connected to the side thereof as shown in Fig. 1. This line may be either a gas line or an electric conduit depending upon the means employed for heating the ironing shoe.

The' frame 1 is provided with socket members 68 to receive tapered legs 69. The legs may be braced near the bottom by means of corner 'castings 70 and cross pipes 7l as shown. Extension pipes 72 may be provided for adjusting the working height of the machine to meet varying conditions. This construction isfree from thexdriving mechanism and permits the machine to be set up on its own framework or the legs may be detached and the machine set on a table or bench.l

In Fig. l the machine is shown in normal position, which is the iioningposition. The

loperator feeds in the articlepto be 'ironed at the right side of the machine, Fig. 1.

When it is desired to move the ironing shoe away from the roller it may be done by hand, as previously described, or it may be done automatically. If automatically, the

operator presses down on the outer edge of the tilting board 36 which revolves the-pivot shaft 20 through the connecting link 39, thereby causing the yoke 22 to engage the clutch 10 with the teeth 9 on the spur gear 8., This transmits motion to the stub shaft 7 which revolves the disk 12 causing the pin 29 to engage the pin 28 and throw out the clutch 16-from the teeth 15 on the large spur gear 14,

' leaving the main shaft idle and roller at rest.

During this operation the button 30 will engage the recess in the disk 12 and cause the clutch l0 to become disengaged from the spur gear. 8 thus leaving the machine idle.

lVhile the stub shaft 7 is being rotated motion is transmitted through lthe crank 43 and the crank arm 44 to the toggle mechanism and causes the arms 52 and 56 to pull the ironing shoe away from the ironing roller and the machine is at rest. To put the machine in operation again all that is necessary is to of the tilting board 36 which again causes the stub shaft to rotate and the disk'12 returns to normal position. This motion of the disk causes the clutch 10 to become disengaged from the spur gear 8 and. allows the clutch 16 to become engaged with the large spur gear 14 on the main shaft, thus revolving the ironing roller. At the same time, and by the rotation of the stub shaft 7, motion is again transmitted through the crank 43 and crank arm 44 and through the arms 52 and 56 `and the shoe is swung to normal position shown in Fig. 1. The stub shaft having rotated 180o comes to rest and the shoe remains in operation relative to the roller.
