To the rea r of projections 1-1, the arms 10 are provided with apertures 1S and 19, which are adapted to receive, in loosely pivoted relation, the cars 20 provided on a air of holding

This spring shifting member has secured thereto, to move therewith, a pair of foot members, which cooperate with a-pair of actuating and holding dogs 21 and 22pivotally mounted at 18 and 1.9, respectively, on the oseillatable arms 10. The foot members 47 are caused to move with the spring shifting member 39 by means of the laterally extending wing portions .49 of the 1 spring shifting member, which fit in-islots inthe flat foot members 47. The foot members 47 he snugly against the side plates 7.

fit

when the heating action has elongated the bar 57, as above described and has moved the dog 21 to release the left toe portions 50, the dog 22 will have swung to the left so thatil's lower edge will lie abore the right hand toe portions 50.

'ith the controlling parts in this position, it will be seen that when the iron is removed from the stand and the spring 1 arts to raise the arms 10 the switch control parts will be mored to the position shown in Fig. -'l in which the dog 2" has pressed down on the right hand toe portions and has depressed the spring shifting member to again more the switch to on position.

As soon as the iron is removed from the stand, the heat controlled bar 5? begins to cool otf and this starts a movement of the dog controlling member which pushes the lowenend of the dog to the right, as seen in Fig. l and if continued long enough, i-.\'entnally causes the dog to release its cooperating toe portions 50 to permit the spring shifting member 39 to move to its upper position under the act-ion of the spring l3 to again throw the switch ofil The construction is such that if the iron is cold and is placed onithe stand, the act of placing it on the stand will throw the switch on and will startthe current flowing through the heating coil in theiron. As

the iron heats up, it transmits heat to aheat A responsive element of the stand and after a predetern'iined desired length of time (five minutes has been foundsatisfactory) the heat responsive element; is heatedsufliciently to release the-dog which is h0lding the switch in on position, whereupon a spring throws the switch to off position. This throwing otf of the switch by the heat responsive element. is in itself an indication that the iron is hot. enough to use. This thermostatic action would prevent current from being left on for a period longer than live minutes in case the user of the iron be unexpectedly called away or for any reason forget toshut; oll the current. Q

.-\s soon as the user considers that -the iron is hot enough to use,;which may be before the thermostat automaticallythrows oil the switch, the ironis removed from the stand and is used in the usual ironing operation. If the iron is removed-from the stand before the thermostatic element has released the switch,- the switch will still be held in on position as explained above. The constructitm is such that if the iron is off the stand for a certain desired predeten mined length of time (2 minutes has been found satisfactory), the cooling down of the thermostatic element will automatically release the switch to permit it to move to off position. This will preventany danger of a. fire. and will also prevent unduewvaste of current incase the user should forget to turn oil the current. or-place the iron back on the stand.

It will honoted that placing the iron on the stand operates to throw the switch on and illfitl-lfllilllg the iron off the stand'opt. the heating up oi the heat responsive element automatically acts to release the. switch after a predetermined length of time and also that the eo oling down of the thermostatic element operates to release the ;\\'it(ll after a redetern'iincd length of time. There is thus a dual action of the thermostatic element to release tlxeswitch and a dual action of the iron controlled lever for throwing on the switch.

in the operation of this device, the operator places the iron on the stand for the first pro-heating period. After the iron has heated sntiiciently to start the ironing, re

tion willithrow the switch-to the on posh tiornif; i has been thrown to the fofiff positi on by the cooling of Ith thermostat-:01" if the tliei-mostatihas not-'cooledi'sutfici'entlj to t h row eleg nce,- itfwill still hold the switch in the I relationaof theftherinostat to the switch'so ;that theeizpansion of the thermal unit will,

ma sholtperiod of time, releasejthejswitch and ciit oil the current.

In operation, if the iron getstoo hot la nid would beap'tf'to s'oiclx;'tlie material being .ironed it is not necessary to turn thefsw 'itch or .pull the plug to cut olflthe burrenQas in; the. period when the -jron is placed I on vjthestand to straightenout or. foldithe iece. tliiitijsto be ironed, the iron maybefp aged cross wise 0n;tl 1 e standiallow'ing the' thermal u nit w, icl'i-fcontrols theswitchi to cooloff and contract, and. throw theswi'tcli on. The operator-can continn to iron until the iron has cooled to a temperature at which it does not iron well. .Then, by placing-theiron bacltoir the standj'n anor nal. position, the switehis automatically thrown and the iron will coimnen ceto heat.

The construction 'is such: that wheiilt he h 'iron is place cross-wiseuon the stand and rests on the side flan esgfitl, the switch will .not bemoved to fon positioi even if the lbottoin ofthe iron should com c down on the controlling arms as the side fiaiigesare high enough so that the arms 10 will notbe moved fil Enough to cause the' movement of the switch to 9011 position,

h c ns ruction i su lithet at, after a predetermined period.

on-f;posi t io ri,ibiiti will reverse the ward movement of the arms 10 which takes place when the iron is placed on the stand, the dog which is released by the heating of the thermostatic element will be the one which acts to hold the switch in on position,- and such that when 'the arms 10 are raised. which takes place when the iron is moved from the stand, the dog which is released by the cooling action of the thermo static element will be the one which is holding the switch in on position. In other words. when the iron is on the stand, the heat released dog is holding the 'switch on, and when the iron is off the stand, the 'cold released dog is the one which is holding the switch in on position.
