11 Claims.

This invention relates to ironing machines and has to do with a light weight readily portable ironing machine intended for domestic or home use.

My invention is directed to an ironing machine of the character stated, which is of exceptionally light weight and is of compact and sturdy construction, so as to be readily portable while occupying but little storage space and being long lived. Further, the machine of my invention comprises comparatively few parts, many of which be formed as stampings, and may be produced at low cost. The roll is driven from a suitable motor, through a driving train comprisa terminal gear movable into and out ofdriving engagement with a gear or pinion fixed to the motor shaft, whereby the motor may run free of parts driven thereby in the ironing operation, when the roll is stopped in the intervals between the passage through the machine of articles being ironed. 1 hat is desirable as permitting free turning of the roll in either direction for positioning thereon of articles to be ironed, while also conserving electrical energy for driving the machine, when an electric motor is used. The roll driving train comprises means whereby the terminal gear and the motor shaft gear or pinion are held in pressure contact for driving the roll, and the pressure between the gears increases with increasing resistance to rotation of the roll. That is advantageous, particularly when friction gears are used, as preventing objectionable slippage be" tween the gears and thereby assuring proper drive of the roll. Preferably, the machine comprises a roll and a cooperating shoe moved to and from the roll by a control lever. This lever-has inoperative position, toward which it is yieldingly urged, and an operative position, means be- 1. provided for automatically locking the lever its operative position and readily releasin it, when desired, for movement to inoperative position. The lever, in its movement from its operative position to its inoperative position, and vice versa. moves the terminal gear of the roll driving train out of and into driving engagement with the motor shaft gear or pinion for driving and stopping the roll, with the advantages above mentioned. Further objects and advantages of my invention .l ap-pearfrom the detail description.

Figure 4 is a sectionalview taken substantially on line ll of Figure 3, on a reduced scale; and Figure 5 is a sectional View taken substantially on line 55 of Figure 3.

The ironing machine of my invention comprises a base IE, oblong in plan, of appropriate width and length, conveniently formed as a sheet metal stamping of channel section both lengthwise and transversely, there being a cushion bead i l of rubber or like suitable material applied over the edge of the depending flange of base I 6. A frame l2, of approximately U shape and formed as a stamping of sheet or plate metal of suitable gauge, is secured to the top of the base 10 adjacent one end thereof in asuitable manner, conveniently by bolting. Frame l2 comprises an upwardly extending inner armi3, which constitutes the inner Wall of the gear housing, as will appear more fully presently, and an outer arm I i connectedtothe inner arm by a bight or base element i5 which seats upon and is secured to base it, conveniently by bolting. A bearing sleeve it extendsinwardly from the upper portion of arm 13 of frame, l2, in overlying relation to base ill. Sleeve Iii is provided, adjacent its outer end, with an outer circumferential flange H which seats against the arm H3; The sleeve I8 is also provided with a reduced extension or hub it fitting through a corresponding opening in arm is of :frame [2, this hub l8 bein threaded for reception of a securing nut i9 screwing thereon and bearing against the inner face of arm is. Sleeve H3 is thus tightly secured to .arm 13 so as to extend inward there from above the base id, as noted.

A roll shaft 29 extends through sleeve i6 and is rotatably supported therein by a suitable bush ing 2 I; Shaft 29 extends inwardly beyond sleeve [6 a substantial distance, in overlying relation to base and has mounted thereon a roll 22; This roll 22 comprises a sheet metal cylinder 23 Within which are secured suitably spaced flanged metal discs, 2Q, 25, and 26.' Disc 2s is provided with a suitable opening accommodating sleeve l6 and the disc 25 has secured thereto a relatively thick nnulus 21 through which and disc 25 the shaft passes. The forward end portion of shaft 20 is slabbed off at opposite sides, to provide a flattened finger 29 which extends through a corresponding opening in disc 26 and through a like opening in a relatively thick annulus suitably secured, conveniently by spot welding, to disc 26. The finger 29 extends inward an appreciable distance beyond the annulus 30 and receives a cotter pin 3| inserted therethrough. As will be understood, the finger 29 fits snugly through the openings in disc 26 and annulus 30 and provides driving connection between shaft 28 and roll 22. A suitable pad 33 is secured about cylinder 23 of roll 22 and is provided with a cover 32, as is known. It will be clear, from what has been said, that the roll 22 is mounted on and secured to shaft 20 for rotation therewith,

A shoe shaft 34 extends through the arms l3 and M of frame l2 and is rockably mounted therein. A washer 35 is disposed about shaft 34 adjacent the inner face of arm l4 and a cotter pin 36 is secured through shaft 34 adjacent the inner face of washer 35. The washer 35 and cotter pin 36 cooperate with arm M to restrain the shoe operating shaft 34 against lengthwise outward movement, as will be clear. An L shaped control and shoe operating lever 38, to be referred to more fully later, is provided, one arm 39 thereof having an opening which receives the shoe shaft 34, the other arm 40 thereof extending along shaft 34 at the back of the latter and being connected to arm 39 by an outwardly bent element 4|. Arm 48 is suitably secured to shaft 34, conveniently by bolting, there being a flat plate 42 set into shaft 34 adjacent the inner end of arm 40 to provide ample seating area therefor.

The shoe shaft 34 extends inward over base It in overlying relation thereto and i disposed below and in back of the roll shaft 20 substantially parallel therewith. A short distance from its inner end, the shoe shaft 34 is mounted in the upwardly extending arm of the angle bracket 44 secured to the under face of base 8, conveniently by bolting, with one arm 45 extending upward through a slot 46 in base l8 and receiving the shaft 34. A shoe supporting arm 48 of channel cross section, conveniently formed as a stamping from sheet or plate metal of suitable gauge, is loosely mounted at its lower end on shoe shaft 34', at the inner end portion thereof and adjacent arm 45 of bracket 44. The shoe supporting arm 48 is provided at each side thereof with an upwardly extending ear 59. The ears 58 receive a pivot pin 5| extending therethrough and through the rearwardly projecting arms of angle brackets 52 seating on and secured to a clamp plate 56. by screw studs and nuts 53 and 54, respectively, which also secure clamp plate 56 to the face plate of the shoe 55, which cooperates with the roll 22. The shoe is of known construction and includes a resistor held against the face plate of the shoe by a clamp plate 56, through which the screw studs 53 pass, as is known. Since, as noted, the shoe 55 is of known construction, further description thereof is not necessary here. The pin 5| is restrained against endwise movement by suitable locking devices or snap rings 58 engaging in grooves formed in the pin 5| and disposed adjacent the ears 58 and the outwardly or rearwardly extending arms of the brackets 52.

A spring 60 is suitably secured, conveniently by bolting, in a transverse slot in shoe shaft 34, extending from the inner end thereof, the spring 60 being disposed within the shoe supporting arm 48. A headed screw 6| is inserted through the spring 68, adjacent the upper end thereof, and passes through an opening in the bight portion of arm 48, receiving on its outer portion an adjusting knob 62 threaded thereon and bearing against the bight portion of arm 48. A compression spring 63 is disposed about screw 6| and confined between spring 68 and the inner face of the bight portion or element of arm 48. From what has been said, it will be seen that when the shoe shaft 34 is turned clockwise, as viewed in Figure 5, the shoe 55 is moved rearward away from roll 22, and when shaft 34 is turned counter-clockwise, by swinging the lever 38 downward into its operative position shown in full lines, the shoe 55 is moved into cooperating relation to the roll 22 and is held in pressure contact with articles passing between the roll and the shoe by the spring 66. The screw 6| and the knob 62 provide means for adjusting the relation between arm 48 and spring 60, thereby adjusting the effective pressure exerted by spring 60 for holding the shoe 55 to the roll 22.

The frame |2 constitutes, in effect, the gear housing of the machine, as will appear more fully later. The roll shaft 29 extends across the frame I2 and is mounted at its outer end in a flanged bushing 65 mounted in the outer arm l4 of frame |2, as shown more clearly in Figure 3. A yoke 66 of inverted U shape is mounted on shaft 29 for swinging movement thereabout and depends therefrom. A spur gear 10, in the form of a flat disc, is fixed on the outer end of a hub 69, which is secured, conveniently by a cotter pin II, to shaft 20, there being a washer 12 interposed between the inner end of hub 69 and nut l9. It will be clear, from what has been said, that the yoke 66 is swingably mounted on the shaft 20 for movement thereabout forward and rearward of the gear housing.

A shaft 14 is rotatably mounted in the lower end of yoke 66, in flanged bushings 15 carried thereby. A spur pinion 16 is mounted on the inner end of shaft 14, the inner end portion 14a of which is reduced and slabbed off to provide a fiat seat for pinion 16 having an opening therein corresponding to this reduced end Portion 14a of shaft 14. Pinion 16 is confined between the inner end of the corresponding bushing and a lock member, in the form of a snap ring ll engaging in a corresponding groove in end portion 14a of shaft 14. The pinion l6 meshes with a spur gear 18 mounted on a counter shaft 19 which is freely mounted in yoke 66 above shaft 14. The gear 18 is confined between the adjacent arm of yoke 66 and a snap ring 88 engaging in a corresponding groove in shaft 19 at the inner face of gear 80, this gear 18 meshing with the gear 10 secured on the roll shaft 20. A snap ring 8| engages in a corresponding groove in shaft 19 at the outer face of the outer arm of yoke 66 and, in cooperation with gear 18 and snap ring 80, restrains shaft 19 against endwise movement in either direction. The counter shaft 19 passes through the upwardly extending arms of a U shaped cross member 82 suitably secured, conveniently by spot welding, to the arms of yoke 66. It will be seen that the gears 10 and I8 and the pinion 16 together constitute a planetary gear train the gears and pinion of which are constantly in mesh, while permitting free swin ing of the yoke 66 about the shaft 20 for a purpose to be described presently.

The outer end portion of shaft 14 is slabbed off from opposite sides to produce a reduced fiat sided element 84. This element 84 fits snugly through openings of corresponding size and shape in two washers 85 and 86 disposed at'opposite sides of disc B'I of a main drive member or terminal gear 83. Disc 81 also has an opening therethrough which snugly receives element a l of shaft I4 and is secured on'element 84 by means of a headed screw 9% threaded into element 84, in cooperation with the washer 86 and an intervening lock washer SI. The main drive or terminal gear 88 also includes a relatively thick rim 92 formed of a tough elastic material, such as synthetic rubber, or a natural rubber. fitting tightly about the circumferential area of disc 38 and bonded thereto in a suitable manner. It will be understood, from what has been said, that when the main or terminal gear 88 is driven the roll shaft 20, and consequently the roll 22, is driven thereby through the planetary gearing above described.

An electric motor M of suitable type is disposed within the frame or gear housing H2 at the lower rearward portion thereof. Conveniently, the motor 84 is supported by means of threaded rods 95 and 95 secured therein, rod 95 being disposed at the upper rearward corner of motor St and rod 95 being disposed at the lower forward corner thereof. Two shouldered cylindrical nuts 9? are threaded on the upper rod 95 and disposed with their reduced portions seating in the lower portions of slots 98 opening upward through the arms of the frame or gear housing I2. Likewise, two shouldered cylindrical nuts Ito are threaded on the lower rod with their reduced portions engaging in forwardly opening slots in the upper portions of arms IllI of bracket H32 suit-ably secured, conveniently by bolting, to the base or eight element of gear housing I2. The motor 95 may be mounted in any suitable manner, though I prefer the mounting means shown as providing for removal and replacement of the motor with expedition and facility. As is shown more clearly in Figure 1, the motor 94 is spaced outward from the inner arm or wall I3 of the gear housing I2 and has a suitable fan or blower Ifiiigof known type, secured on the inner end of its shaft HM. As will be understood, the fan I as serves to cause circulation of cooling air over and about the motor 94. -1

The motor shaft IE4 is provided at'its other or outer end with a gear or pinion secured thereto. Conveniently the outer end portion of shaft Illa is provided with a plurality of generally lengthwise shallow grooves providing a pinion Illfi suitable for frictional engagement with the elastic rim 92 of the main drive or terminal gear 88. The pinion IE6 is disposed substantially in the plane of gear 83 so that by swinging the yoke 65 rearward into what may be termed a drive position, gear 88 may be brought into driving engagement with pinion I06 so as to be driven thereby, thus driving roll 22 from the motor M. By swinging the yoke (it forward into what may be termed its stop position, the'terminal gear 83 may be disengaged from pinion I fit of the motor shaft Iil l, thus stopping the drive of the roll 22, The arm 39 of the control and shoe operating lever 38 extends forward from shoe shaft 34 adjacent the inner arm or wall I3 of the gear housing I2. This arm 39 is offset inwardly at its forward portion 39a, which extends forward alongside the outer face of a latch plate I08. This plate IDS is suitably secured, conveniently by bolting, to the inner arm or wall I3 of the gear hous-v ing I2, spaced a short distance inward therefrom. Plate I 08 extends upward above the raised position of lever 39, indicated in dot-and-dash lines in Figure 5, and is provided, at its lower portion, with a downwardly and rearwardlyextending slot Hi9 opening at its upper end through the forward portion of plate I533, this slot being of approximately L shape and being provided, at its rearward end, with an upward extension Iii of arcuate shape. A handle member III is pivoted, at II2, on arm 39 of lever 38, a short distance from the forward end thereof. The handle member III extends forward from lever 38 and is provided, at its forward end, with a reduced tang IE2 on which issecured a gripping member H3. The member MI is also provided with a downwardly extending finger H4, in the lower end of which is secured a reduced stud I i5a of a shouldered latch pin I I5 provided, at its inner end, with a reduced neck I Ifia having a head I I6 of materially greater diameter than neck I I60: (Figures 3 and 5). An angle stop member II? is suitably secured, conveniently by spot welding, to the forward endof lever 33 and extends up ward a short distance above the latter, being provided at its upper end with an inwardly extending finger I I3. This finger I it is disposed to contact a bumper lit, in the form of a ring or collar of rubber or other suitable material, disposed about an anchor post ILI secured to wall I3 of the gear housing i2 and projecting a substantial distance inwardly thereof. A tension spring IE3 is anchored at its upper end to a post I2 1, secured to and projecting inward from inner wall It of gear housing i2, adjacent the upper rearward portion thereof. The spring I23 is anchored at its lower end to an angle member I25 secured in a suitable manner, conveniently by spot welding, to the inwardly offset forward portion 39a of arm 39 of the control and shoe operating lever 32? As will be understood, spring 523 urges the lever 38 upward from its operative full line position shown in Figure 5 to its raised inoperative position indicated in dot anddashlines. When the lever 38 reaches its latter position, finger H8 of angle member i ii. contacts the bumper I28 and in cooperation therewith limits upward movement of the lever 38.

The lower arm I2? of angle member I25 extends outward from lever 38 and in front of the downwardly extendingarm I28 of an L shape-cl leaf spring I29. The upper arm I39 of spring I253 seats upon the bight element of cross member 32 and is secured thereto in a suitable manner, conveniently by headed screws I3: passing through arm I39 of spring I25, cross member 82 and a plate I32, the-screws {SI receiving nuts I33 threaded thereon, A tension'spring I35 is anchored at its upper end to the inner end of post I2I and extends downward and rearward therefrom, with its lower end anchored to the cross member 82, conveniently by meansof one of the screws I3I. The tension spring IE5 is effective for swinging the yoke it forward, as limited by contact of spring I29 with 51711212? of angle member I25, into its stop position, when the control and shoe operating lever is raised to its inoperative position.

Swinging of the yoke #36 to its stop position moves the terminal gear til out of driving engagement with the pinion H36 of motor shaft I6 3.

thus stopping drive of the roll 22. When the lever 33 is swung downward into its operative position, arm I2? of angle member :25 swings the yoke 55 rearward, by means of leaf spring I23, in opposition to the tension spring "2 This rearward swinging of yoke 66 moves the rim 92 of terminal gear 89 into engagement with pinion I06 of motor shaft I04 shortly before the lever 33 reaches its full lowered operative position. The further downward movement of lever 38 causes rearward flexing of leaf spring I29, which then becomes effective for yieldingly holding the rim 92 of terminal gear 88 in pressure contact with pinion I 06 of motor shaft I04. That assures effective driving engagement of the terminal gear with the motor shaft pinion.

In the operation of the machine the roll 22 is driven clockwise, as viewed in Figure 5, the gear I8 is driven counter-clockwise, and the pinion I6 is driven clockwise, as indicated by the arrows. It will be seen that resistance to rotation of roll 22, during the ironing operation, reacts on the gear "I8 so that the yoke 66 is thereby subjected to pressure tending to swing it rearward about roll shaft 20, this pressure increasing as the resistance to rotation of the roll 22 increases. That is advantageous as assuring increasing pressure contact between the rim 92 of terminal gear 88 and the pinion I06 of the motor shaft I04 in accordance with increasing resistance to rotation of roll 22, thereby guarding against objectionable slippage between the terminal gear and the roll shaft pinion. That is conducive to continuous and smooth operation of the machine.

In order to establish driving connection between the roll and the motor, when an article to be ironed has been properly positioned upon roll 22, the control and shoe operating lever 38 is swung from its raised inoperative position down ward to its lowered operative position. When the lever 38 is in its full raised position, indicated in dot-and-dash lines in Figure 5, the neck I I Go of pin I I5 is in contact with the downwardly and forwardly inclined front edge portion I08a of the latch plate I08 above slot I 09, portion I08a of plate I08 serving as a cam and cooperating with pin II5 for holding the handle III in position with the main or body portion thereof substantially aligned with portion 39a of arm 39 of the lever 38. By grasping gripping member I I3, the handle member III is swung downward, carrying with it lever 38. In the downward movement of member II I, the reduced neck I IBa of pin II5 enters the upper end of slot I09 and passes downward therein and then rearward, the neck IIBa of pin II5 then moving upward into the extension H at the rearward end of slot I09. That occurs when the lever 38 has been moved into its full lowered operative position, in which it is then latched, the tension spring I23 being ineffective for disengaging the neck IIGa of pin II from the upward extension I I0 of slot I09 and returning lever 38 to its raised position. In order to stop the roll 22, the handle member III is swung upward, thus disengaging neck Ilsa of pin II5 from the upward extension IIO of slot I09 and moving it into the forward portion of this slot. That releases the lever 38 which may then be moved to its raised inoperative position by tension spring I23, this upward movement of lever 38 being controlled, if desired, by means of the handle III, the neck I IBa of pin I I5 travelling upward along the forward edge of plate I08 in contact therewith. It will be seen that the movements of the control and shoe operating lever 38 are effective for moving the shoe to and from the roll and also for swinging the yoke 66 to drive position and stop position, so as to establish and disestablish driving connection between the roll and the motor in accordance with movement of the shoe to and from the roll.

The frame or gear housing I2 is provided with a suitably formed cover I3'I seating at its lower edge on base I0 and secured to the outer arm I4 of the frame or gear housing I2 by suitably disposed screws I38 threading into arm I4 and pads or blocks I39 secured thereto, conveniently by spot welding. Preferably, a reinforcing arm I40 of appropriate form, which may be an aluminum casting, extends between the inner and outer arms or walls I3 and I4 of the frame or gear housing I2, at the upper ends thereof, and is secured thereto in a suitable manner, conveniently by means of screws. This arm I40 guards against possible spreading apart of the upper ends of walls I3 and I4 of the gear housing and assures proper alignment of the parts carried thereby. The cover I3! is, of course, appropriately formed to enclose the gear housing and the parts carried thereby, including the arm I40. The cover I 31 is provided, through its front wall, with a vertical slot I42 of sufficient extent to accommodate the movements of handle member I I I passing therethrough.

An insulating grommet I45, of rubber or other suitable material, is secured through an opening in base I 0. The grommet I45 receives an electric cord I46 passing therethrough and beneath base I0, suitable connections being provided between the wires or conductors of cord I45 and the resistor of shoe and the motor 94, as is known. A plug cap I4! is attached to the free end of cord I46, whereby the machine may be plugged in or connected to the local or house circuit.

My instant invention is, in certain respects, in the nature of an improvement over the ironing machine disclosed in my co-pending application for a portable domestic ironing machine with a friction drive, Serial No. 634,419, filed December 12, 1945, and now Patent No. 2,578,928 dated December 18, 1951.
