It will therefore be seen that with this construction the operator while ironing can either press the forward pedestal or the rearward pedestal towards thetop surface of the shell or both pedestals may be simultaneously7 moved, andas soon as the operator removes the pressure the spring will-return' the pedestals to their outward position as is illustrated in Figure 1.

In order to provide a convenient arrangement in which the iron may be rested without bodily lifting it, the sides I5 and I6 of the shell are so constructed as to have longitudinally extending

portions

46 and 41. These side portions are so positioned as will be seen from an inspection of Figure 6 that when the iron is rocked over on its side the iron will be supported on a base between the grip portion 21 and either one of the

side portions

46 or 41 depending upon which way the iron is rocked. It will furthermore be seen that due to the resilient construction between the handle and the shell as the operator removes his hand from the grip, the grip will drop down onto the base but will do so with a minimum amount of shock due to this resilient connection. It will be understood that by designing the resilient characteristics of thespring forthis rocking movement and by allowing the holes in the top surface I4 of the shell to be slightly larger than the diameter of the studs 32 and 33, this limited resilient rocking movement will be allowed.

In order to connect the conductor 20 to the terminals I8 and I9 of the heating unit, a socket construction 50 is provided which extends through an opening 5I in an enlarged portion of the rear pedestal 28. This construction may take any suitable type and in the arrangement illustrated in Figure 1, the electrical cord is permanently connected to the iron due to the

shoulders

52 and 53 which tightly surround a restricted portion 54 in the bore through which the socket passes. Also, if desired, a pilot light 55 may be provided in a suitable recessed portion 56 in the front pedestal and conductors 51 connect the light in the electrical circuit in the manner illustrated in Figure 4.

In order to provide an improved construction for minimizing the transfer of heat from the sole plate to the shell so that when the iron is rocked over on its side, the shell will not be sufficiently hot to burn the base upon which the iron is placed, I provide a sole plate construction IiII as is generally indicated in Figure '1 which includes a plurality of shoulder portions 6I through 64. It will be seen from Figure 8 that when the shell is assembled with the sole plate that the lower surfaces of the shell will abut against the shoulder portions 6I through 64 thus leaving

passages

65 and 66 through which air may circulate inside the shell. It will also be seen that

openings

61 and 68 are provided in the top of the shell through which extend the conductors and air may circulate out through these openings and in between the legs of the spring clips as is illustrated by the arrows in Figure 8.

Although I have shown and described particularVV embodiments of my invention, I do not desire to be limited to the particular embodiments described, and I intend in the appended claims to cover all modifications which do not depart from the spirit and scope of my invention. I claim as my invention:
