THOIAS J'. HADIGAN, OF NEW YORK, N. Y.

SADIBON.

Application led January 3, 1922. Serial No. 526,593.

To all whom t may concern:

Be it known that I, THOMAS J. MADIGAN, a citizen of the United States, residing at NewYork, in the county of New York, Statev of New York, have invented certain new and useful Improvements in Sadirons; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art towhich it appertains to make and use the same.

My invention is an improvement in sad irons, and relates particularly to mechanism for holding normally open circuit controlling switches for electrically heated -sad irons closed during the preliminary heating of the iron. In my prior application, Serial No. 516,302, filed November 19, 1921, I show and describe an improvement in electrically heated sad irons, wherein a normally open circuit controlling switch is disposed below the grip of the handle, in position to be closed, 'and to be held closed, by the vgrasp of the user on the ip. Before commencing the ironing operation, the current must iow for a time, to heat the iron to the proper temperature, and with the type of iron forming the subject matter of the above a plication, it is necessary to hold the switch c osed maiiually durin this preliminary heating.

Any mec anism in connection with the iron or handle, for holding the switch closed is objectionable. The user is liable to forget to release such mechanism when -the iron is set aside, with consequent overheating, and liability to damage. `Even when an iron provided with such mechanism, that is with means` in connection with the iron oi' handle for holding the switch closed, is set upon a heat insulated stand during the heating of the iron, there is liability to damage, should for instance, the iron be accidentally displaced from the stand.

In the present invention, I provide means in connection with a usual type of heat insulated stand for the iron, and wholly independent of the iron and handle, to hold the switch closed while the iron i's on the stand, and so arran ed that when the iron is displaced froin t e stand, the switch is at once released from the holding means. I also provide a standard so constructed that it may be connected to the usual type of -insulated stands consisting of spaced lates without the use of screws, rivets, bo ts or clamps, merely by pushing a portion of the standard between the plates.

In the drawings:

Figure 1 is a side view of the stand with the iron in place, and with the handle partly broken away to show the switch,

Figure 2 is a section on the line 2-2 of Figure 1,

Figure 3 is a side view of the handle, partlv broken away, to show the switch, and with the switch in open position.

In the vresent embodiment of the invention, the iron comprises a body 1 of usual constructiomhaving connected therewith a handle 2, spaced apart from the-body by plates 3. One of these plates 3 carries the usual plug socket 4, in which is received the lug 5, and one of the lead wires in the ilexible connection 6 is looped into the handle as indicated at 7 A switch is arranged within the handle, the switch being interposed in the loop 7 and a switch arm v8 is provided being normally open. The switch arm 8 is disposed beneath the grip or handle 2 in such position that it may be engaged by the fingers of the user when the handle is grasped, to move the arm into closed position. The ends of the loop 7 are connected to contact plates 9, one of which is shown, the said plates being insulated -from each other and supported by a suitable base 10, within a recess 11 in the grip.

The switch comprises members 12 and 13, pivotally connected, one of the members 12 being pivoted to the base as indicated at 17, while the other member 13 carries contact buttons 14 for engaging the contact plates 9, to electrically connect said plates. Springs 15 and 16 are so connected with the members 12, and with the base, that the members cannot hold the position of Figure 1, when the arm 8 is released, but immediately return to the position of Figure 3. The arm 8 has an angular, portion 18, which hooks over a pivot pin 19 on the base, and the angular portion engages a pin 20 on the member 15, swing said members into the position of Figure 1, the springs 15 and 16 returning the parts to the position of Figure 3, when the switch arm is released The arrangement is such that the Switch im must be heid against uit in order to hold the circuit closed, and

aside the swltch whenever the .iron is set opens the heating circuit.

for closing the switch, the switch- With the above construction of iron, it is necessary to hold the switch closed, for a time, before using, in order that the iron may attain the proper temperature for ironing. The use of an means in connection with the handle or wrt-h the iron for holding the switch closed would be objectionable, because the user might forget to release said means, thus retaining the clrcuit closed when the iron is Set-aside. When the iron is on the heat insulated stand, however, over-heating is of importance only in so far as it may damage the iron. Hence I provide mechanism 1n connection with the stand, for holding fthe switch'arm in closed position, when the iron is on the stand, but wholly independent of the handle and of the iron, so that the switch arm is immediately released when the iron is displaced from the stand. The said mechanism comprises a standard 21, having means at one end for engaging the stand, and having at tthe other a lateral arm 22 extending into position to engage the switch arm 8 and move the same to close the switch when the iron is on the stand. The standard in the present instance, is constructed of wire, bent to shape. Re-

4 ferring to Figure 2, it will be seen that that portion of the standard which engages the' stand is bent into inverted V shape, as indicated at 23, the V being of suflicientdepth such that the apex thereof will engage one of the lates 24 of the stand, whlle the arms of the will engage the other plate 25 of the stand. The extremity of this portion of the l,standard has a laterally bent Vlug 26, which prevents tilting of the stand sidewise. The lateral arm 22 is formed by doubling the wire upon itself. The standard is only Aintended to be used durin the preliminary heat' of the iron, or w en the iron is set aside or a few moments, to prevent cooling of the same. When the iron is placed on the stand after the ironing is finished, the switch arm 1s permitted to take the position of Figure 3, that is it is permitted vto move into open position, When in this position, the switch arm wlll be below the lateral arm of the standard, and the circuit will be open.

It will be obvious that the standard might be constructed in many different ways, the essential features thereof being the lateral arm and the means for engaging the stand for holding the standard erect.

In order to protect the insulation of the looped lead Wire 7, I arrange upon said wire beadsvindicated at 27, the said beads being of any suitable material.

I claim:

1. 'In combination with an electrically heated iron having a normally open circuit controlling switch provided with an operating arm disposed belowthe handle in position to be closed by the fingers of the user when the handle is grasped, a heat insulated stand for the iron having means for engaging the switch when 'the iron is on thestand to close the switch and released from the switch when the iron is disposed from the stand, said means comprising a standard frictiohally engaged with the stand and having a lateral arm extending beneath the handle when the iron is on the stand 2. In combination with an electrically heated iron having a normally open circuit controlling switch provided with an operating arm beneath the handle in position to be grasped and closed b the ngers of the user when grasping the andle, a heat insu- 7lated stand comprising connected plates spaced apart from each other, and a standard having means extending between the plates and engaging said plaftes to hold the standard upright, the standard having a lateral arm extending beneath the handle of the iron when the iron is on the stand.

i 3. In combination with an electrica-ll heated iron having a normally open circurt controlling switch provided with an operating arm dlsposed below the handle, a stand comprisin spaced connected plates, and a standard aving 'means engaging between the plates to support the standard in erect position, and having -means for engaging the switch to close the same when the iron is placed upon the stand.

In testimony whereof I aliix my si ature.

THOMAS J. MADI AN.
