manner andJfor'the purpose.heronafterlset,:tortilla The "solo plate is-heated bia-anyfsuitebVA ef-elez-ltrie element which'is' energized by wires 48 leading from a source of electric energy. An indicating light 159 and a switch 50 are connected to the source of electric energy in series with the heatn ing element.

The temperature of the sole plate is governed by a thermostat 52, located within the head 44 and adjustable to a position in Whi'ch it will maintain the sole plate at the desired temperature, and which is subsequently locked in that position. The thermostat is connected to the electric circuit in series with the switch.

In order to prevent override in the temperature of the sole plate, either way, the top 54 of the 3 portion of the head 44 which houses the thermostat 52 is left open as shown in Figs. 4 and 5. By this arrangement, and by placing the thermostat directly on the sole plate, the temperature of the latter is held constant between close and rather critical limits. For example, it was found that, if the thermostat was wholly enclosed by the head in which the sole plate is mounted, it did not cool off in time to energize the heating element of the sole plate and the temperature of the latter dropped below the desired value. ,Y

Conversely, if the thermostat was subjected to ambient temperatures, it energized the heating element of the sole plate prematurely and the temperature of the latter rose above the predetermined value.

The arm 24, the spring 26, and the sole plate 42, are enclosed by a fixed and attractive casing 56 which conceals all working parts except the switch and the indicating light. Also, the movement of the arm 24 is so arranged that, when the machine is at rest the front end of the arm, and, hence, the sole plate will be raised to a position in which the bottom of the sole plate is flush with or is slightly above the lower edge 58 of the front portion of the casing 56. This prevents accidental contact with the heated sole plate and protects its smooth, lower, working surface from injury. When the front end 4D of the treadle 34 is depressed, the front end of the arm 24 moves downwardly so as to bring the underside of the sole plate into contact with the pressure pad I6, and when the pressure on the treadle is relieved the spring 26 raises the front end of the arm 24 and moves the sole plate into its upper concealed position.

When it is desired to use the apparatus, the switch 50 is turned on and, when the sole plate has been heated to the predetermined temperature, the operator spreads the damaged portion of the fabric over the pressure pad IG and depresses the treadle to cause the sole plate to apply heat and pressure to the fabric. If a stocking is to be so treated, it is drawn over the anvil until the damaged portion comes to rest over the pressure pad I6.

The amount of pressure to be applied and the length of time during which pressure is applied can be determined by the operator according to the nature and extent of the damage to be repaired and according to the denier of the yarn from which the fabric is made. However, by limiting the downward movement of the front end of the treadle, as shown in Fig. 2, the downward movement of the sole plate it also limited so that it will not exert excessive pressure on the fabric regardless of the pressure exerted by the operator on the treadle.

In order to facilitate operation, the machine is provided with one or more arms, on each of its opposite sides, for supporting the stockings before and after they are mended. For example. on the right and left hand sides of the machine, as viewed in Fig. 1, the machine is provided with two arms 69 and 6l, respectively. The arms 60 and 6| are provided with sleeves 62 which are freely rotatable about the legs or upright members 64 of the frame l0, the sleeves being prevented from slipping down on said legs by means of set screws or the like 66. When the machine is in use, the arms 60 and 6| are swung outwarly so as to project at an angle to the planes of the sides of the machine. In this position the arms extending from one side of the machine can be used for supporting the stockings to be mended and the arms on the other side of the machine can be used to support the stockings that have been mended. When the machine is not in use, the arms 60 and 6l are folded underneath the platform I0 so as to be out of the way.

What I claim is:

Apparatus of the character described which apparatus includes a frame, a table top carried by said frame, a fixed anvil located above the table top and having an upper, smooth working surface, a rocker arm carried by said table top, a heat and pressure applying head having a lower, smooth, working surface and carried by one end of said arm in vertical registration with said anvil, means for normally retaining said end of said arm and said head spaced upwardly from said anvil, means for actuating said arm to bring the working surface of said head into limited pressure contact with the working surface of said anvil, means for heating said head, a thermostat within said head, said head having a Ventilating opening in the upper portion thereof, and a fixed casing carried by said table top and adapted substantially to enclose said arm and said head when the latter is in its upper position, the peripheries of said working surfaces sloping away from the plane of contact of said surfaces.
