Claims. (01. 38-60) pact, eilicient, portable ironing machine that is inexpensive to construct and light in weight so that it may be easily carried about.

Another object of my invention is to provide in a portable ironing machine wherein the motor and driving mechanism are contained within a hollow roll, a simple means for mounting the roll whereby the roll may be removed quickly and easily to uncover the driving mechanism and motor.

Another object of my invention is to provide supporting means for the roll and for the shoe which cooperate to provide for self-alignment between the roll and the shoe.

Still another object of my invention is to provide supporting means for the roll and the shoe which cooperate to provide yielding pressure engagement between the roll and the shoe when these parts are moved into operative relationship, and wherein the supporting members themselves provide resiliency suflicient to accomplish this object without the use of springs.

Another object of my invention is to provide a unique means for supporting the shoe which comprises a single member at least a portion of which may be submitted to torsional strain; thus providing a yielding pressure engagement between the shoe and the roll when these parts are brought into cooperative relationship.

A further object of my invention is to provide supporting means for the roll and shoe so constructed and arranged as to give a maximum clearance for the free passage of the materials being ironed at the supported end of the roll.

Still another object of my invention is to provide a simple, manually operated toggle mechanism for subjecting the shoe supporting member i the ironing time of an article may be increased.

Other objects and advantages of my invention will appear from the following specification taken in connection with the accompanying drawings, in which: A

Figure 13 is a detailed section taken transversely of the shoe.

Figure 14 is an exploded section similar to Figure 13.

Figure 15 is a partial elevation parts being broken away. showing the shoe operating handle in two positions.

Referring now more particularly to Figures 1 and 2, the machine comprises the base 20, the roll support 2 l, the roll 22, the shoe support 23 and the shoe 24. The motor 25 and driving mechanism 26 are contained within the roll, as shown in Figure 4.

The base member 20 is preferably stamped from sheet metal and comprises a substantially shallow inverted trough 30 which is open at the bottom. (See Figures 4 and 9.) In the preferred form, this trough is deeper at the rear than in the front in order to accommodate mechanism later to be described. The bottom is closed by means of a cover plate 3i suitably secured by means of the brackets 32 and screw studs 33. A channel-shaped member 34 is secured within the base transversely thereof, preferably by spot welding. The member 34 serves the double purpose of rendering rigidity to the top surface of the trough while providing ,means for supporting mechanism presently to be described. In order to prevent scratching a surface upon which the machine may be placed, I have provided the rubber piec which extends around the base and projects below the bottom thereof.

v-"The roll supporting member 2| is preferably formed from a piece of metal tubing shaped generally in the form of a U, as shown in Figure 4. The lower arm 38 of the U is flattened somewhat, as shown in Figure 8. An aperture 31 of corresponding shape is provided in the end of the base member 20. A second aperture 38 of similar shape is providedin the cross member 34. In forming the aperture 38, a portion of the member 34 is bent over to form the bracket 39 into which is threaded a set screw 40. The lower arm 35 is inserted into the apertures 31 and 38 and rigidly secured thereinby means of the set screw 40. The upper arm 4| of the supporting member 2| is provided at its free end with a female thread 42 for a purpose presently to be described.

On the arm 4| and substantially directly over the end of the base 20 is secured a spider 45 which, in the preferred form, has three arms 46 spaced substantially 120 apart. Adjacent the outer ends of the arms 46 are mounted the antifrlction rollers 41 by means of the studs 48.

The guard member 49 is secured to the spider arms 40 by means of the brackets 50 and screws 5|. The guard member 49 is provided with a plurality of apertures 52 to permit the circulation of air therethrough. The motor 25 and driving mechanism 26 are secured to the supporting member 4| by means of the flanged member 55 which is provided with a central boss 56 having a male thread 51 which is screwed into the female thread 42 to secure the member 55 to the sup porting arm 4|.

A supporting frame 58 is secured to the member 55 by means of a plurality of studs 59. The motor 25 is in turn secured to the supporting frame 58 by means of the screws 60. A bearing sleeve 6| is mounted on the arm 4| adjacent the end thereof. Driving spider 62 is mounted with a running fit over the bearing sleeve 8|. A retaining member 63 is rigidly secured to the support 4| by means of the set screw 64 and serves to limit the endwise motion of the spider 52.

The spider 62 carries an internal gear 61 which, through the gear train 68 shown, in Figure 6, is connected to the motor 25. An overrunning clutch 69 is provided in the gear 68' so that when the motor is stopped, the roll may be freely revolved by hand. The spider 62 is provided with a plurality of driving arms 10 (Figure 9). The outer end of each of said arms 10 is provided with a groove H for a purpose presently to be described.

The roll 22 comprises a metal cylinder 12 having suitable padding l3 and pad cover 14. A plurality of lugs 15 which, in the preferred form are stamped inwardly of the inner surface of the cylinder 12, are formed complementary to the grooves H in the ends of the arms 10 of the drive spider 82. The proportions of each of these lugs are such as to form a tight sliding fit with a corresponding groove 7| so that when the roll is in place, the roll will turn with the spider 62 without wobbling. The position of the anti-friction rollers 41 is so arranged as to snugly support the inner end of the roll 22 while permitting rotation thereof. The roll 22 is secured against endwise motion by a single bracket 18 rigidly secured at one end by the screw 11 to the spider 82. The outer end of the roll 22 is provided with a plurality of inwardly extending brackets 18 one of which is provided with an aperture and a screw 19 to secure the roll to the bracket 15. A substantially conical guard provided with the apertures 8| is secured to the brackets 18 by means of the screws 19 and 82 to close the opening at the free end of the roll while allowing circulation of air through the apertures 8|.

The motor 25 is preferably of the shaded pole induction type and is provided with an armature shaft 85 which projects a substantial distance beyond its supporting bearings. The inner end of the shaft 85 is provided with gear teeth 86 adapted to mesh with the first gear in the train 68.

Adjacent the opposite end of the shaft 85 is mounted a centrifugal switch 81. An insulating sleeve 88 is mounted on shaft 85 and carries a pair of slip rings 89. A pair of brushes 90 are supported on insulating bushings 9| and contact the slip rings 89. The radial member 92 is mechanically and electrically fastened to one of said slip rings 89. The spring member 93 has one end rigidly fastened to the member 92. The member 93 extends inwardly and a substantial distance across the shaft 85 and at an angle thereto. Adjacent the free end of the spring member 93 is fastened a contact point 94. A second radial member 95 is electrically and mechanically fastened to the other slip ring 89 and has a contact point 96 fastened adjacent the outer end thereof positioned to cooperate with the contact 94 on the-spring member 93. When the armature of the motor 25 rotates, centrifugal force tends to separate the contacts 94 and 95 because of the angularity of the member 93 with respect to the shaft 85.

At the extreme outer end of the shaft 85 is secured a fan 9! for the purpose of forcing a cooling current of air over the motor when the machine is operated.

In order to provide an efiicient shoe and one in which the heating element may be operated at high ratings while insuring long life to the heating element, I prefer to construct the shoe in the following manner:

The sole plate 98, which extends substantially the length of the roll 22 is provided with retroverted edges 99 for a purpose presently to be described. An electric heating unit I00 is placed next to the sole plate. The heating unit comprises a resistance element here shown in two sections |0| extending longitudinally of the unit and secured between two sheets of mica I02 or other suitable electrical insulating material. A heat insulating I03 is placed over the heating unit I00. The back plate I04 is provided with two depressions I05 extending longitudinally thereof and positioned so as to press the pad I03 downward over the portions of the heating unit |00 containing the resistance elements |0| to form said unit into intimate contact with the sole plate=-T98 when the shoe is assembled. This structure reduces the resistance of the heat flow path from the electric resistance unit |0| to the sole plate 98. In assembling the shoe, the back plate M4 is slid lengthwise and secured in place by pressing the rods I06 and I0! inwardly under the edges 99, thus firmly clamping the back plate I04 in position.

A finger guard I08, preferably formed of a piece of metal tubing. is mounted in front of the forward edge of the shoe on heat insulating collars II! which are in turn supported on the intumed ends of the rod I01. The guard I08 is designed to keep the operators lingers out of contact with the shoe.

The shoe support 23 comprises a substantially U-shaped member, having an upper arm H and a lower arm III. The lower arm III is slightly oflfset to the front as shown in Figure 9, but extends substantially parallel to the arm H0. The lower arm III is rotatably supported in the base 20 by inserting it in suitable apertures provided in the end of the base 20 and in the cross member 34 as indicated at II2 and H3 of Figure 8. A groove in the arm I II adjacent its end and the ring II4 serve to hold the arm in the assembled position. The shoe 24 is secured to the upper arm IIO of the support 23 in a manner presently to be described. It becomes apparent that tuming the arm III in its supports H2 and H3 will swing the shoe 24 toward and away from the roll 22.

The mechanism for swinging the shoe comprises a toggle I I5 (Figure 8) one end of which is secured by means of the pivot II6 to-a lug II1 extending outwardly of the member 34. The other end of the toggle H5 is pivotally secured to the lever II8 which, in turn, is rigidly fastened to the member I I I by means of a set screw II9. In thepreferred form, one link I of the toggle is a turnbuckle which may be extended or contracted, thereby increasing or decreasing the effective throw of the toggle. One end I2I of a link I22 is bent at right angles thereto and used as the pivot between the two toggle links. The portion I2I is here shown as secured in place by means of a cotter pin I23. The opposite end I24 of the link I22 is bent at right angles to the portion I2I and is secured by means of a cotter pin I25 in a short lever I26 which is rigidly fastened to a rock shaft I21.

The rear end of the shaft I21 is journaled to the back plate of the base 20, as shown at I28. The forward end of the shaft I21 is joumed at I29 in the forward wall of the base 20 and projects therethrough. Shaft I21 is held in place by means of the groove and snap ring I30, as indicated in Figure 8. The forward end of the shaft I21 is provided with a hexagonal socket I3I and a counterbore I32.

The detachable operating handle I35, preferably formed of hexagonal stock, is bent in the form of an L. The upper end of the operating handle is provided with a ball I36 or other suitable fixture adapted to fit the hand of the operator. The arm I31 of the rod I35 has a short cylindrical portion I38 formed adjacent the end thereof, the outer end of which is tapered, as at I38. (See Figure 11.) The portion I38 is split, as at I40. The split cylindrical portion I38 is so proportioned as to provide a frictional fit in the counterbore I32 in the member I21. Thus, the operating handle I35 may be readily inserted in the socket I3I while being maintained with some reasonable degree of security when in place.

When the handle I35 is moved to the left, as shown in Figure 1, rock shaft I21 will be rotated to the left, the lever I26 will throw the connecting link I 22 to the left and straighten the toggle II5. As the toggle H5 is straightened it will rotate the lever arm II8 which, in turn, twists the arm III and will thus swing the shoe 24 into contact with the roll 22. The turnbuckle I20 is adjusted so that when the toggle is straightened it will not only bring the shoe into contact.

with the roll but will give an additional twist to the lower arm III, thus subjecting the arm to a torsional stress. As the arm I II is made of an elastic metal, it will hold the shoe 24 with yielding pressure against the roll 22. As both the roll support 2I and the shoe support 23 are formed of substantially U-shaped members, both of these members will twist slightly when the roll and shoe are forced into contact.

Furthermore, as varying thicknesses of material are passed between the roll and the shoe, due'to the resiliency of the supporting members 2I and 23, the roll and shoe will separate allowing the material to pass between them.

If the operator desires to have both hands free to guide the work into the machine, the handle I may be inserted in the socket I3I so that the handle I 35 hangs downwardly as shown by the broken lines in Figure 15. With. the handle I35 in the downward position and extending below the table on which the machine is being used, the handle may be operated by the knee.

The shoe 24 is secured to the arm IIO of the shoe support 23 in the following manner:

A bowl shaped depression I40 is formed in the back plate I04 substantially centrally thereof.

'The head I of a bolt I42 is inserted in this depression with the threaded shank extending outwardly from the plate I04. A bracket I43 having suitable apertures is passed over the threaded portion of bolt I42 and secured to the back plate I 04 by means of the screws I44 and I45. Suitable backing pieces I46 and I41 are provided into which the screws I44 and I are threaded. Sufficient clearance is provided so that the bolt I42 may be turned by means of the slot I48. A threaded aperture is provided in the arm IIO adjacent the end thereof, into which the bolt I 42 may be threaded. A second aperture is provided to accommodate the extension I50 of the screw I45. Thus, the screw extension I50 and the bolt I 42 serve to maintain the shoe 24 in alignment with the arm IIO of the shoe support 23. If it becomes desirable to adjust the shoe 24 so that it is brought into greater or less pressure contact with the roll 22, this may be accomplished by inserting a screwdriver in the slot I48 of bolt I42 and turning the bolt so as to move the shoe relative to the arm H0. The lock nut I5I is provided to lock the bolt I42 in the adjusted position. It is contemplated that factory adjustment of the shoe pressure will be obtained by adjusting the turnbuckle I20 of the toggle mechanism H5. The additional adjustment feature of bolt I42 is provided so that tressure adjustment can be made quickly and easily in the field as compression of the roll pad 13 may require. l

Aii'ixed to the back plate I04 of the shoe 24 and substantially at the center thereof is a housing I53 which is provided with louvres I54 to permit circulation of air therethrough. Mounted within the housing is a thermostatic switch I56 which is provided with a handle I51 located on the outside of the housing I 53. Within the housing I53 is also a light socket I58 for supporting an electric light bulb I59. The socket IE8 is mounted on the bracket I43. The front face of the housing I 53 is punched out to form the letters Hot. The purpose of the louvres is to allow air to circulate through the housing to cool the light bulb I59 and thus increase its useful life.

The electrical wiring of the apparatus will now be described. Contained within the base 20 is a self-winding cord reel 66 on which is wound a suitable length of two conductor cable ISI. One end of the cable (6i projects through an aperture provided in the base member 20 and is connected to the attachment plug I62. The other ends of the cable 16! are connected to the slip rings I61 and I65 schematically indicated in Figure 3. A pair of brushes 66 contact the slip rings I6 and 65 to which all internal electrical connections are made.

Two wires 61 and i 61' lead from the brushes I 66 upwardly through the tubular shoe supporting member 23 into the housing I53. These leads are connected to either side of the light socket I56. Lead I61 is connected directly to the heat ing unit I06. The other lead I61 is connected through the thermostatic switch I56 to the other side of the heating unit (00. The thermostatic of electric energy, the lamp I59 will light up in the indicator located on the ironer shoe. Thermostatlc switch I56 is then set by means of the switch I56 is provided with four positions-an 011' position when the circuit is entirely broken, a high, a. medium and a low heat position. When set in one of these heat positions. as soon as the shoe attains the desired temperature, the thermostatic switch opens. When the temperature drops below a prescribed limit, the thermostatic switch closes again and repeats the opening and closing, as required, to govern the temperature.

It is here to be noted that the light I59 will always be on whenever the attachment plug I62,

is connected to a source of electrical energy, and this is so whether or not the thermostatic switch is in the ofi position and whether or not the mbtor is running.

Three motor control switches are provided. The manual switch I10 is connected to the lead I61, the other side of the switch I10 being connected to a switch "I. Switch "I is mounted on the cross member 34 and has a push contact member I12 which is disposed in the path of the toggle joint I2I. Thus, when the operating handle I35 is moved so as to straighten the toggle joint I2I and bring the shoe into contact with the roll, switch "I is automatically closed. The other pole of switch I" is connected directly to the motor 25. Switch I13, shown in Figure 3, is used for changing the speed of the motor 25. One side of the switch I13 is connected directly to the motor 25, the other sid being connected to the lead I61. Thus when switch H3 is in the closed position and switches I10 and "I are closed, the motor 25 is connected directly to the line and the motor runs at normal speed.

The centrifugal switch 81 is used to obtain less than normal speed of rotation of the motor 25. One side of the switch 81 is connected directly to the motor 25, the other side of switch 81 is connected to bridge the switch I13 to the lead I61. Thus, when switch I13 is opened, the current will pass through the centrifugal switch 81 to reach the motor 25. The tension of the spring arm 93 is set to permit the contacts 94 and 96 to separate when motor 25 attainshalf normal speed, and thus cut oil the current supply. As the motor speed varies around the set speed, the switch opens and closes, thus maintaining the desired speed within narrow limits of Variation.

A spark suppressor circuit comprising a resistance I15 and condenser I16 may be provided, connected across the contacts 94 and 96 of the centrifugal switch 81.

If it is desired to clos the shoe against the roll without rotating the roll, switch I10 may be opened, in which case, the motor will not start handle I51 to a temperature suitable for ironing any particular material. This temperature will vary from a low temperature for silk to a high temperature for linen. The thermostatic switch I56, when cold, closes the circuit through the heating lement I00. When the temperature of the shoe has risen to the selected point, the thermostatic switch I56 will open thereby cutting of! the source of current to resistance I00 and thereafter will periodically close and open, maintaining the temperature of the shoe within a reasonable range of selected temperature. For operatio of the roll at normal speed, switch I16 is moved to the on" position, and likewise switch I13. The operator places a piece of material to be ironed on the roll and then advances the roll slightly then swung to the right, which moves the shoe into contact with the ironer roll and at the same time closes switch "I, which sets the motor into operation, causing the roller to revolve and carrying the material to be ironed around with the roll and beneath the ironer shoe. If the operator desires to stop the roll with the material in the ironing position, it is only necessary to throw the switch I10 to the "off position. This is called the pressing position of the switch I10. Operation of the handle I36 to open and close the roll will not start the motor when the switch I10 is in the ofi or pressing position. If the operator desires to operate the roll at half speed, the switch I13 is placed in the open position or, as indicated on the name plate, in the oiT position. This breaks the direct connection of the motor to the line I61 and the circuit is completed through the brushes and the centrifugal switch 81. In this position, with the switch I10 closed, when the handle I36 is moved to the right to close the shoe against the roll, switch "I is closed and the electric circuit is completed from the line I6I through the motor and centrifugal speed switch 96. If the speed of the motor exceeds a predetermined amount, the switch 96 opens, causing the motor to slow down. As the motor speed drops below the predetermined speed, the switch 96 closes, thus by the rapid opening and closing of the switch 96 the speed of the motor and hence the speed of the roll are controlled. This speed is set at the factory to be approximately one-half normal speed.
