This inventionh'elates to universal ironing machines and is an improvement on the device of my prior Patent No. 1,623,187, filed February 9, 1924.

It has become desirable to provide an improved ironing machine of the type shown in the above mentioned application and it is accordingly an object of this invention to provide an efficient machine of this class.

lVith the above and other objects in View as will be apparent, this invention consists in the construction, arrangement and combination of parts,all as hereinafter more fully described, claimed and illustrated in the accompanying drawings On the drawings:

As shown on the drawings:

Numeral 1 represents a suitablehousing a part of the for the ironing machine having a removable section 2 rigidly secured thereto. The section 1 is hollowed as shown in Figure 5 and is adapted to support therein a shaft 3 on bearings 4 which are held in place by cap members 5. The shaft 3 is securely held against longitudinal movement in the casing section 2 by means of the shoulders 6. .The left hand cap member 5 as viewed in Figure 5 is recessed so as not to interfere with nuts said apertures 13 at all 7 which hold the movable portion of the left 1 the arm of the operator in case his hand happens to be between the roller 8 and the member 9 when the latter is being lowered. The presser member 9 is suitably supported by longitudinally spaced arms 11 which are pivoted on a shaft 12 within the housing 1, the. housing 1 being apertured as at 13 for this purpose. The surface of the housing 1 has a cylindrical shape adjacent the aperture 13, said shape being concentric with the shaft 12. A sleeve member 14 is provided for closing times and is rigidly secured to the arms 11 exterior-1y of said apertures 13 and is also of a shape concentric with the shaft 12. The arms 11 extend rearwardly in the casing 1 and are pivotally connected as at 15 to a collar member 16. The collar member 16 receives-slidably therein arod 17. Said rod 17 has thereon a second with along the length thereof and a pair of nuts 19 which are adapted to hold said collar 18 securelyin upward-position on said 'collar member 18 relatively movable thererod 17. A spring 20 surrounds the rod 17 and is adapted to be abutted by the

collar members

16 and 18. The rod 17 threadedly engages in a clamp member 20 which is pivoted as at 21 to a safety dog 22, a link' 23 and a connecting rod 24 having a slot 25 therein. The link 23 is pivoted as at 26 to a bracket 27 rigidly secured to the housing 1 and form a toggle with rod 17. The safety dog-22 is hookshaped substantially as shown and is adapted to engage over a rod 28 rig:

idly secured to the inside of the housing 1 when the presser member 9 is in upward position and the mechanism just described is in a dotted line position as shown in Figure 10. The connecting rod 24 has thereon a lug 31 which is adapted to engage with a lug 32 on the dog 22 when the pres-ser member 9 is near its low position. A crank 33 on a shaft 34 which rotates anti-clockwise and which is suitably supported in the housing 1 on roller bearings 35 is adapted when in the position shown .in Figure 4to force the dog 22 by reason of the

lug

31 and 32 rearwardly for straightening the toggle and pressing the presser member 9 firmly against the drum 8. As shown in Figure 11, the rod 28 is provided at its ends with bosses 29 which are slidably mounted-in a suitable casting and which may be adjusted by the set screws 30. It is therefore possible to adjust the rod 28 so that the dog 22 will not drop therefrom until the presser member 9 is in a satisfactory and safe relation to roller 8. The mechanismfor controlling the movement of the crank 33'will now be described. The shaft 34 has rigidly secured thereon a frictional clutch housing 36. A shaft 34 axially aligned with the Shaft 34 and movable relatively therewith is supported to the left of said shaft 34 as shown in Figure 5 by means of roller bearings 36 in the casing 1 and has keyed thereon a conical clutch member 37. A collar member 38 is loosely mounted on the shaft 34 and by means of a lever 39 pivoted on the shaft 40 and connected to an operating lever, 41 by, means of lever 39 rigidly secured on said shaft 40 and rod 39" is adapted to abut a spring 42 for forcing the clutch member 37 into clutching engagement with the member '36 on the shaft 34. The shaft 40 oscillates with the lever 39 and has rigidly secured thereon a lever 43 which extends therefrom normally to the lever 39. A spring 44 secured with one end to the casing 1 and the other end to the outer end of the lever 43 is in line with the lever 43 when the same is substantially intermediate of its extreme are of movement such that said spring 44 will act to throw the collar member 38 out oft-hitching engagement or in clutching engagement depending upon whether or not lever 43 is below or above. respectively, its central point of movement. A pair of lugs 45 (Fig. 6) diametricallypositioned on the clutch housing 36 are in line with the crank 33 (Fig. 6) when the latter is in position for pressing the presser member down, as shown in Figure 4. A dog 46 held in the position on the collar member 38 and pivoted thereto as shown in Figure 6 isadapted to be abutted by the lugs 45 when the presser member. 9 is in downward pressed position for throwing the collar member 38 to the left as shown in Figure 6 to release the

clutch members

37 and 36, thus preventing the crank from releasing its pressure on the presser member 9. A brake band 47 surrounding the clutch housing 36 is connected by means of the

rods

48 and 49 and link 50 to the lever 43 and is adapted to frictionally engage said housing 36 and hold the crank shaft 34 in position when the clutch member 37 is released from clutching engagement with said housing 36. It will be noted that when the lug 45 strikes thelug 46, the lever 39 and shaft 40 will be given a partial rotation. Consequently the lever 43 on the shaft 40 will be actuated for applying the brake when the clutch is thrown out. When it is desired to raise the presser member 9 it is necessary to throw the lever 41 in position for again engaging the

clutch members

37 and 36. The resilient mounting of the dog 46 enables it to be forced into position over the lugs for permitting

clutch members

37 and 36 to again engage to further rotate crank 33 to raise the presser member. The mechanism for controlling the continuous and intermittent rotation of the drum 8 is similar to that of my above mentioned prior application and will now be described. V

A worm wheel 51 is secured on the shaft 34 and is adapted to be driven by a. worm 52 on a motor shaft 53 of a motor 54 supported in the housing 1. A pair of

pinions

55 and 56 are loosely mounted on shaft 34 and are provided with jaw clutches upon their adjacent faces. A clutch member 57 is slidably splined upon the shaft 34 between the

pinions

55 and 56. This clutch is adapted to be actuated by a yoke lever 58 secured upon a shaft 59. The shaft 59 is suitably connected to an operating lever 60 for actuating the same'to throw the clutch 57 into engagement with the

pinion

55 or 56 as may be desired. A shaft 61 is rotatably supported'on roller bearings 62 in the casing 1, said shaft 61 being parallel to shaft 34. Keyed on the shaft 61 is a gear wheel 63 which engages with the pinion 55. A sprocket wheel 64 is also keyed to the shaft 61 and is adapted to continuously drive the roller shaft 3 by means of sprocket wheel 65 thereon and chain 66 when the lever 60 is actuated to throw the clutch 57 into engagement with the pinion 55. A second gear 67 is loosely mounted on the shaft 61 and is adapted to engage with the pinion 56' of the shaft 34. A ratchet wheel 68 is secured upon the shaft 61 and is adapted to be engaged by a pawl 69 (Figure 7) pivoted upon the gear 67. A spring 70 connected with the free end of the pawl 69 and the gear 67 normally tends to withdraw the pawl from engagement with the ratchet wheel. A compression spring 71 extends from the pawl 46 for engaging under an arenate guard 72. which is slidably mounted upon

rods

73 and 73 for pressing the pawl into engagement with the ratchet wheel.

It will be evident that aslong as the end of the spring 71 which is provided with a bevelled head engages under the arcuate guard 72, the pawl willbe held in engagement with end of a cable 7 7 attached the ratchet wheel 68 for rotating the shafts 61 and consequently the roller shaft 3. How-. ever, when the pawl rides out from under the.

arcuate guard 7 2 the spring 70 will withdraw the pawl from the ratchet wheel 68 thereby preventing further rotation of the

shafts

61 and 3. The guard 7 2 is connected to the shaft 59 by a link 74. The gear 67 is provided with a cam 75 extending laterally from the side thereof. This cam is adapted for engaging against the side of the arcuate guard 72 and shifting it laterally upon the

rods

73 and 73 for moving the same out of the path of the pawl 69 and simultaneously rotating the shaft 59 through the link 74 for shifting the clutch 57 to neutral position for stopping the rotation of the gear 67. The arcuate guard 72 has the same angularity of are as the arcuate surface of the pressing member 9 so that the circumferential movement of the ironing roller 8 will equal the arcuate extent of the pressing member 9. The arc'uate guard 72 is adapted to be manually shifted by the crank 60 when said crankis actuated to reengage the clutch member 57 with the pinion 56. A counterweight 76 is secured upon the lower thereby to a peg on the gear 67. This counterweight is suitably guided by rollers 78 secured to the casing. This counterweight is adapted to return the gear 67 after each actuation to its initial starting position with the pawl 69 under the V rolling action.

upper end of the arcuate guard 72 as shown in Figure 7. Lever 58 is suitably connected through lever 58 and rod 58 to the operating lever 60 for actuating the same to throw clutch 57 into engagement with the pinion or 56 as may be desired.

A pair of brackets 79 extend from the casing 1 for supporting an ironing board 80 below the roller 8 upon which a certain amount of hand ironing may be done. 7

The operation of the machine will now be described. Let it beassumed that it is desired toiron articles which require merely a The lever will be thrown into position connecting the pinion 55 with the clutch member 57 so that the shaft 34 driven by the member 54 through the worm 52 and worm wheel 51 will drive the roller shaft 3 through the gears 63, sprocket wheels 64. chain 66 and sprocket Wheel on said roller shaft-3. The lever 41 will then be thrown into position for engaging the

clutch members

36 and 37 and thepresser member 9 will be lowered by gravity. the

clutches

36 and 37 engage, causing the slotted connecting rod 24 to move rearwardly so that the pivot point 21 also moves rearwardly by the weight of the presser member 9 though controlled by rod 24. The lug 31 011 the connecting rod 24 will engage with the lug 32 of the dog 22 when the presser member 9 is in almost lowered po- 'sition and when the crank 33 reaches the position shown in Figure 4 said presser member 9 will be firmly but resiliently held in downward position against the roller 8 by means of the spring 20. When the crank 33 has reached the position shown in Figure 4 with the presser member 9 in downward pressed position, lugs 45 on the clutch member 36 will have disengaged the clutch member 37 by abutting the dog 46, and the lever 43 through means of the brake band 47 connected thereto will prevent the clutch member 36 and crank 33 from over running so that presser member 9 will continue to be held in the downward position. When an article has been passed between the roller 8 and the presser member 9, another may be inserted without stopping the machine so that a continuous rollingor ironingaction results. The guard 10 is also adapted to act as a feed board for flat pieces, such as handkerchiefs; etc. WVhen it is desired to stop the machine or raise the presser member 9, it is only necessary to actuate the

levers

60 or 41 respectively.

It will be appreciated that when the presser member or buck 9 is in elevated position, the parts are in the dotted line position as shown in Figure 10. In this position, the safety dog 22 is supported upon the rod 28. Now as the buck 9 is lowered, it is obvious that the safety shown in Figure 4 before the shoulder 31 on the slotted link can engage the shoulder 32 on the dog for applying pressure to the toggle 1823 for straightening the same and applying pressure upon the buck.

Now let us assume it is desired to press certain classes of garments or articles-which cannot be readily ironed by a continuous rolling action, but require an intermittent action. Assuming that the presser member 9 is in elevated position and the lever 60 and clutch 57 connected thereto are in neutral position as shown in Figure 6,the garment or articles to be pressed may then be inserted between the roller 8 and the pressing member 9." When the garment has been properly positioned, the lever 41 maybe actu- 8 as heretofore described. The presser member 9 is then raised by again actuating "the lever 41 as heretoforedescribed. The

roller 8 may then be rotated a distance equal article maybe advanced a predetermined to the arcuate surface of the presser member 9 by actuating the lever 60 in the reversed direction for engaging the clutch member 57 with the pinion 56. IVhen the clutch member 57 engages with the pinion 56 the pawl 69 will be in the position shown in Figure 7 except that the arcuate guard 72 will be engaging with the spring 71 for causing the pawl 69 to engage with the ratchet wheel 68. \Vhen the gear 67 has rotated sufficiently so that the-spring 71. rides off the arcuate guard 72, the pawl 69 will disengage from the ratchct 68 and before it can again reach the are 7 2 for again engaging the ratchet 68 the cam 75 will have engaged with the guard 72 and shifted it laterally to disengage the clutch 57 from the pinion 56 so that the roller 8 will only move enough to present a new surface beneath the presser member 9. The counterweight 7 6 will always return the gear wheel 67 to initial starting position as shown in Figure 7 so that when the lever 60 is'again actuated to engage the clutch member 57 with the pinion 56, the roller 8 may again be rotated so as to remove the pressed portion beyond the confinement of the presser member 9 to bring any non-pressed portion to juxtaposition with. respect to the presser member 9. The roller however may be stopped at any time when pleats or ruffles are encountered by simply throwing the clutch member 57 into neutral in the position shown in Figure 6. From the foregoing it will be evident that this ironing machine may iron garments by rolling action or simply by pressing action in which the pressed distance. Accordingly any kind of garment or piece of fabric may be ironed 1n the machine.
