Application filed October IO, 1923. Serial No. 667,739.

7 The present invention relates to ironmg machines and more particularly to the type in which an iron and a bed are employed having a relative movement between them. An object of this invention is to provide an improved controlling means for an electrical heater that effects the heating of the iron. A further object of the invention is to control the electrical heater through the relative movement between the iron and the bed,

so that when separation takes place between these two elements, the supply of current to the heater will be out ofi.

To these and other ends, the invention consists of certain parts and combinations of parts, all of which will be hereinafter described; the novel features being pointed out in the appended claims.

Referring more particularly to the drawings, 1 indicates the receiving table -supported on a base frame 2. .The receivin table has at opposite ends side frames 3 an 4, which support, above the receiving table, a rotary bed 6, the shaft 7 of which is supported in the side frames 3 and 4. A motor 8 supported on the side frames 3 is geared through a gear: ing in the casing 9 to the shaft 7, so as to effect the rotation of the bed 6. The details with a slot 27.

of this gearing do not form part of'this invention, and they are illustrated in an application filed by me on the 14th day of April, 1923, Serial No. 632,182, to which reference may be had for the purpose of ascertaining the construction of a gearing for performing this operation;

The iron comprises, in this instance, a curved cast plate 10 and a sheet metal plate 11 forming a chamber between them in which the heating strips 12 are arranged, these heating strips being of any commercial form and enclosed within electrical nonconducting material 13 which lies in contact with the heating surface 10, the strips being arranged in parallel relation and held in place y straps 14. Asbestos, mineral wall or other non-conductor of heat 15 may fill the remaining portion of the chamber and serve to confine the heat to the heating wall 10 of the iron.

In the illustrated embodiment of the invention the iron is supported by two arms 16 pivoted at 17 to the side frames 3 and 4 so as to swing toward and from the bed 6, but it will be understood that any relative movement between the bed-and the iron may be employed. With the end in view of moving the iron toward and from thebed preferably through the motor 8, the shaft 7 carries a camming device 18 which is adapted to be connected and disconnected from the shaft 7 and which controls the movement of the iron as will be hereinafter set forth. The connection of the cam 18 with the shaft 7 is preferably effected by providing a clutch member 19 on the cam 18 for cooperation with an internal gear or clutch member 20 formed on the bed 6. A spring 21 mounted on the cam 18 tends to move the clutch member 19 on the cam into cooperation with the clutch member 20,.so that driving connection between the bed and the iron operating mechanism will be effected.

In order to control this clutch connection between the drum and the iron operating mechanism a finger bar 22 may be employed preferably supported in a groove 23 in .the feeding table 5 and on two arms 24 which are pivotedto a rod 25 connecting the side frames 3, and 4. A spring 26 acts on this finger bar to hold it normally in a raised position. One of the arms 24 is extended and has near its free end a portion formed Above and below this slot are two cams 28 and 29, respectively, the

cam 28 serving to shift the clutch member 19 when the finger bar 22 is depressed and the cam 29 serving to shift the cam portion 19 out of connection with the drum when the finger bar 22 ,is elevated. For fuller illustration and description of this construction reference may be had to application, No. 632,182, hereinbefore mentioned.

The operating means for the iron embodies, in this instance, a rock shaft 30 journalled in the iron and having two arms 31 extending therefrom and pivotallyconnected at 32 to two links 33 which in turn are pivoted at 34 to the side frames 3 and 4, the links 33 with the arms 31 forming toggles. One of the arms 31 is extended at 35 and in this extended portion a sleeve 36 is journalled, the sleeve having a pitman or rod 37 slidable therein and the rod being surrounded by a helical spring 38 which abuts at one end of the sleeve 36 and at the other end. a collar or nut 39 on the rod. This rod is pivoted at 40 to a two arm lever 41 which in turn is pivoted at 42.2 Above its pivot it has journalled therein a roller 43 which cooperates with the cam 18. cam 18 is so shaped that as it rotates after being moved in connection with the internal gear 20, it efiects the movement of the lever 41 on its pivot 42 which in turn effects the movement of the iron first toward the bed and then away from the bed. The

cam surfaces 28 and 29 so control the cam.

the pivot 42 is supported on a link 44 which is pivoted at. 45 to the side frame 3, this link swinging to carry the pivot of the link 41 away from the cam 18 so that after the cam has shifted the iron to the intermediate position away from the bed, the iron may be shifted to the extreme position as shown in Fig. 9. Movement of the link 44 may be effected by a lever 46 pivoted at 47 to the side frame 3 and also pivoted at 48 to a link 49 which is pivoted at 42 to the link 44. It is apparent that the swinging of the lower end of the lever 46 outwardly at the With the end in view of controlling the current to the electrical heater, there are provided two conductors 50 and 51 leading through a sheath 52 to a switch casing arranged on one end of the iron. A portion 53 of this switch casing is formed integrally with one of the end walls of the iron, while a portion 54 is held to the portion 53 by bolts 55 so that it may be removed in order to expose the switch. The conductor 50 leads to a switch contact 56 supportd on an insulating base 57 in the switch casing member 53. This insulating base also supports a switch contact 58 which by a conductor 59 connects with one of the terminals of a snap switch 60 of any suitable construction. From this snap switch a conductor 61 leads to one of the terminals'of the electrical heater, while to the other terminal of the heater the conductor 51 is connected. The contacts 56 and 58 are adapted to be connected by a connector 62 in the form of a U shaped member, one arm of which connects with each of the contacts, this U shaped member being secured by a screw 63 upon an insulating piece 64 which in turn is secured by a bolt to a plug 65 fitted in the laterally turned end 66 of the locking member 30 which is in the form of a tube, this construction being provided in order that the greater portion of the parts used in this machine may also be used in'the gas heated machine, shown in application No.,

It is apparent that, when the iron is in cooperation with the bed 6, the U shaped connector will bridge the contacts 56 and 58 so that current will pass from the con-.

duetors 50 and 51 to the electrical heating means. It is' also apparent that when the iron is swung away from the bed, the switch will be automatically opened, as shown in Figs. 8 and 9, so that it is lmposs'ible to overheat the iron'.

The operation of the invention will be understood from the foregoing, but it may be summarized as follows: Assuming that it is desired to start the machine with the 1 parts in the position as illustrated in Fig. 8, the motor 8 is first started and then the snap switch 60 is turnedto on position. Thereafter, the finger bar 22 is depressed and immediately released. This permits the clutch member 19 to engage the clutch member 20 so that the cam 18 is turned 180, being stopped through 'the release of the clutch member 19 from the clutch member 20 through the cam 29. In making this movement, the cam shifts the lever 41 on its pivot 42 and moves the toggle formed by the members 31 and 33 in a direction to lengthen the latter, thereby shifting the iron into cooperation with the bed 6. At the same time, the rock shaft 30 is turned so that the connecting member 62 of the ing means and causing the latter to heat- 'the ironing surface 10. If it is desired to switch will connect the contacts 56 and 58, thus establishing a circuit through the heatmove the iron away from the bed 6, the finger bar is again depressed and immediately released so that the camming device 18 is again shifted 180, this time permitting the roller 43 to move inwardly and the toggle 3133 to break, the iron 10 moving away from the bed 6 under its own weight and being assisted in its action by the spring 38 which is placed under compression when the ironing surface 10 cooperates with the bed 6. At the same time the shaft 30 is oscillated and moves the connecting member 60 out of cooperation with the contacts 56 and 58. In some instances, it is desirable to move the iron to an extreme position away from the bed 6 and this is effected by shifting the lever 46 so as to shift the pivot 42, while the iron is in the position shown in Fig. 8. This causes the iron to move in the extreme position shown in Fig. 9.

From the foregoing it will be seen that there has been provided an ironing machine in which the current to the electrical heating appliance is cut off automatically as the iron and the bed are separated and in this way the overheating of the iron due to the failure of the operative to turn off the current, after the iron has been moved away from the bed, is obviated. Furthermore, should the iron become too hot it is merely necessary to separate the bed and the iron to effect the cooling of the latter.
