RED'DIG, F KEW GARDENS, NEW YORK, ASSIGNOR 'I'O GBAYBAR ELECTRIC GOMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK IRONING MACHQINE Application filed August 31, 1927. Serial No. 216,503.

This invention relates to an ironing machine primarily adapted for household use, and more particularly to the combination of such a machine with a kitchen table.

The invention has for its primary object to provide a combined structure answering the demand for space conservation in the modern kitchen by combining with an ironing machine for general domestic ironing a kitchen table. A further object is to conceal from view that portion of the apparatus used exclusively for the ironing when it is not 1n use, at the same time protecting it from dust and mechanical injury.

A further object is to provide means for driving the work supporting roll independently of the ironing shoe operating mechanism, and to conceal the roll driving means from view.

A still further object is to provide power means for moving the heated ironing shoe into and out of operative relation with the roll independently of the actuation of the roll.

Reference being had to the drawings, the frame side members 10 and 11 are connected and spaced at their bases by the tie rods 12 and the rotatable shaft 13. The side members 10 and 11 have rearwardly extending arms 14 which support the ironing roll 15. The ironing shoe 16 is rigidly connected to the shaft 13 by means of the shoe supporting levers 17, but is capable of oscillating about the upper ends of said levers. The table legs 18 are connected to the frame end members 10 and 11 and the upper front closure member 19 is secured to the front pair of legs. A trough 20 extends from below the rotatable shaft 13 upwardly to the front of the machine leaving the opening 21 at the front of the table. The opening immediately below the curved trough 20 thus permits th'e'operator to get as close to the machine as desired by providing clearance for his knees. The feed table 22 is pivotally hin ed to the upper closure member 19 and is o a width sufiicient to completely cover the opening 21 when the said feed table is folded downwardly when the ironing machine is not in use. The rear closure member 24 extends from the upper face of the legs 18 to below the bases of the frame side members 10 and 11 and carries a flange 25 at its upper face flush with the tops of the table legs 18. The table top 26, preferably made of sheet metal appropriately reinforced, has depending flanges 27 on all sides, the rear flange there of being pivotally connected to the rear closure member 24 at its upper face 25 by means of the hinge 28. The dependent flanges 27 of the table top are of height sufficient-to rest snugly against the tops ofthe legs when the table top is in its normal horizontal position at the same time housing the upwardly projecting portions of the roll 15 and the shoe 16. The depending flanges 27 are so constructed that their outer faces when the table top is horizontal are flush with all the side members and the legs, thereby eliminating projecting parts. The side members 29 are pivoted about vertical pivots 30'conven-- iently located directly in front of the rear table legs and are provided with knobs 31 for conveniently swinging them rearwardly. The exposed surfaces of the table top, the depending flanges, the closure members and the i legs are preferably enamelled. The legs 18 are preferably provided with casters 32 and are made telescopic enabling the height of the combined ironer and kitchen table --to be adjusted at will by the operator. Drying racks 34 are conveniently located on the an der side of the table top 26 supported in the depending end flanges.

The roll is rotatably supported upon hollow fixed shaft secured against rotation by means of the set screw 36 in the frame side member 10. The motor supporting yoke 37 is mountedupon the hollow shaft 35 within the periphery of the roll 15. The shaft of the roll driving motor 38 carries the fan Vents 54 are provided in the roll heads, the

39 and the worm 40. In order to reduce the speed of the motor 38 to that required for effective ironing by the roll, a worm reduction gearing 41 is mounted in the housing 42 bolted to the yoke 37. The worm meshes with the worm gear 43 on the shaft of which worm 44 in turn meshes with worm gear 45. The worm 46 on the shaft carrying worm gear in turn meshes with worm gear 47keyedto the shaft 48 which is rotatably mounted in the frameside member 11 by means of roll bearing 49. The roll bearing 50 rotatably supports the shaft 48 on the worm gear housing 42. The roll head 51 is inned to the rotatable shaft 48 while the iiead 52 is rotatably supported upon the hollow shaft 35 by means of roller bearing 53.

motor supporting yoke and in the worm gear housing, permitting a. current of air to circulate through the roll propelled therethrough with the aid of the fan 39. The

current supply leads 55 for the motor pass throu h the hollow shaft 35 and may be conswitch 57 conveniently located at the front of the machine and readily accessible to the operator;

To the rear of roll 15 and movable relative 1y thereto, there is mounted the heated ironing shoe 16 carried by the arms 17 and ivotally attached to the upper end thereo by pins 60, permittin' the shoe to oscillate into gripper seating re ationship with the roll.

e arms 17 extend downwardly and are rigidly aflixed to the shaft 13 rotatably supported in the lower rear portion of the frame side members 10 and 11. To the shaft 13, at any convenient portion thereof, is keyed the arm 61 in the outer end of which carries the disc 62 through which the eccentric rod 63 projects. The free end'of the eccentric rod 63 is threaded and is operatively connected to' of the shoe drive motor 69. The dash-pot button switch conveniently mounted at the front of the machine and readily accessible to the operator carries an arm 71 insulated from the button by means of a non-conductor 72. The dash-pot of the switch includes'a cylinder. 70 having the piston 71' and spring 73' of switch-button 70 therein, and a valve .to ironing or after ironing.

7 2 permitting slow escape of air from the cylinder 70 to release the piston 71' and break the previously closed contact between the arm .71 and the leads 73 and 74 after a predetermined interval. Equivalent timing mechanism for retarding the opening of switch 7 0 may be employed with] equal facility. The rotatable shaft 75 carries fixed thereupon the worm gear 67 and the sleeve 7 8 electrically insulated therefrom however by means of the sheath 79. A The discs'76 and 77 are of a ma terial which is an electrical conductor and are in electrical contact with the sleeve 78 and 1y adjacent to the roll 15. Side closure members 29 are then swung-outwardly and may be used for supporting the work preparatory There are no obstructions at the ends of the roll 15 when the side members 29 are in position as shown in Fig. 3 thereby enabling the ironing of material of greater width than the roll upon my 7 im roved machine. necte to the house mains 56 by means of the witch 70 is thereupon depressed bringing the arm 71 in contact with the conductors 7 3 and 74 and closing the circuit from the electric house mains through the shoe drive motor 69. The rotation of worm 68 causes the rotation of worm 67 and shaft 75 at the same time advancing the shoe 16 toward the roll 15. Rotation of shaft 7 5 carries with it the discs 76 and 77, thereby advancing the insulating segment 80 from beneath thebrush 81 and completing the circuit through the house mains and electric motor through the disc 76, sleeve 78, disc 77 and brush 82. Reopening of the switch 70 by its spring 73 is deferred by dash-pot 70'71 until after'the shoe motor 69 has rotated disc 76 sufficiently to disconnect brush 81 and insulating segment .80. However, the motor 69 is still connected to the source of power suppl until the other segment 80 contacts with the brush 81 thereby breaking the circuit. The throw of the cocentric rod 63 and'the tension of spring 64 are so adjusted that durin the rotation of a half revolution of the sha 7 5, the shoe 16 is brought into operative contact with the roll 15. The ironing shoe 16 is now resiliently held against the roll 15'by means of spring 64', thereby enabling the ironing of materials of varyingv widths.

In that the power operating mechanism for the roll and for the shoe are absolutely independent one. of the other, the ironing shoe 4 first-named means for stopping sai may be brought into operative. position without rotation of the rol' This enables-the operator-to perform any pressing operation, on the machine that may be required, such as pressing of trousers, pleating, etc. The pressure of the shoe against the roll may be varied by the operator byadjusting the tension of spring 64 by bringing up or loosening nuts 66 For the usual continuous ironing of'miscellaneous materials, the switch, 57 i is closed, thereby rotating the roll.. The fan-v39 mounted upon the roll driving motor shaft prevents over heating of the motor and; serves to cool the roll during the continuous ironing operation. The ironed materials pass between the roll and shoe and dro into the, trough 20. below the roll from WllICll they are removed at the convenience of the operator.
