4 Claims. (Cl. 68-26) This invention relates to sadirons and more particularly to a safety, self-heating sadiron; that is, a sadiron which incorporates one or another of various classes of means whereby to heat the iron.

It is an object of the present invention to provide a sadiron with means whereby the free iron, that is, an iron, the handle of which has been released, will automatically be elevated to a distance above the material being pressed by the hot iron sufliciently to preclude possibility of scorching the material and prevent ignition of the material as happens when the hot iron, especially those of the self-heating type, is left resting on the goods being pressed.

A further object is to provide an elevating means acting normally to lift the iron from the supporting surface on which it may be resting just as soon as the hand of the operator is removed from the handle of the iron. In this connection a further object is to provide means to lock the, iron handle down in effective position to restrain the elevating means so long as the thumb of the operator is resting, in. a normal ironing position, along the handle of the iron so that reaction of the elevating means is made ineffective on the hand of the operator and is taken by the locking means; this being only effective to retain the handle so long as the operator directly applies light pressure to the looking means.

The invention consists in certain advancements in this art as set forth in the ensuing disclosure and having, with the above, additional objects and' advantages as hereinafter developed, and whose construction, combination and details of means, and the manner of operation will be made manifest in the description of the herewith illustrative embodiment; it being understood that modifications, variations and adaptations may be resorted to within the scope, principle and spirit of the invention as it is more directly claimed hereinafter.

Figure 1 is a side elevation of the iron in its normal, elevated position as to a supporting sur- 1 face.

Figure 2 is a rear end view of the iron.

Figure 3 is a side elevation showing the iron as lowered to ironing position and with the elevating means retracted to unobstructed position.

Figure 4 is a detail sectional end view showing the locking device in effective, handle restraining position.

In its illustrated form, the iron includes the conventional pressing body 2 provided with any formof heating unit; the present iron being of the electric type provided with electrode posts 3 for the application of an electric cord connecter, not shown. Adjacent to the front end 60 of the iron is a fixed standard 4 whose upper end is bifurcated to receive a blade 5, with a notched corner 6, projected from the swinging end of the iron handle 7. The handle 7 is connected to a cross pivot 8 fixed to the upper ends of jack posts 9 whose lower ends slide through a transverse bar 10 having side legs 11 straddling the iron body 2 and provided with forwardly extending feet 12 carried to a point beyond the center of gravity so that the iron will rest stable in elevated position while carried by the legs 12, as in Fig. 1. The lower ends of the jack posts 9 are fixed to the iron body 2.

In order to effect the automatic and normal elevation of the iron body to a lifted position, expansion springs 13 are provided and are here shown as surrounding the jack posts 9 and react between the pivot bearings 14 and the top of the cross piece 10 connecting'the legs 11.

The rear end of the handle '7 is provided with a rearwardly projecting horn 15 for a pivot 16 of the upper part of a link 17 whose lower end is connected by a pivot 18 to a bearing 19 forming a part of the cross piece 10.

In operation, the footed legs 11 rest on a supporting surface and the expansion springs 13 are sufliciently strong to press the pivot blocks upward and through the connected posts 9, lifting the iron body 2 to the desired safe distance above the supporting surface. vSince the link 17 is connected to the leg cross connection 10 and is connected to the horn 15 of the iron handle 7, it will be seen that the link 17 forms an anchor for the adjacent end of the handle 7 and this is swung to an upright position as shown in Figs. 1 and 2. It is only necessary to grasp the upright handle and press it down to the closed position, Fig. 3, when it will lodge in a lock lever 20 having an up-turned arm which is bifurcated at 21 to receive the blade 5 of the handle and is provided with a slight retaining shoulder 22 which moves into hooking position over the blade 5 when pressure is applied to the'finger rest 23 of the lever 20; this being of the bell crank order 105 and having a supporting pivot 24' in the standard 4.

The normal position of the rest 23 is such that the thumb of the right hand will lodge naturally and comfortably on the thumb rest 23 so that the retaining hook 22 will be kept in position over the handle blade 5 so long as the o'perator'is actually engaged in ironing operation. Instantly the hand is removed from the handle 7 the springs 13 pull the handle blade from the free hook 22 and snap the handle to an upright position at the end of which action the legs 11 are projected down to the supporting surface and thereafter the iron body 2 is lifted a safe distance from the supporting surface to insure cir-' means, a jack post fixed to the iron body and,

having head shoulders, across-bar above the body having footed side legs, a spring device compressed by and between said cross-bar and said jack post shoulders, ahandle hinged to said post and operatively linked to the said bar, and manually set means for securing the handle in a lowered position to, and for manual operation of, the iron; said handle operative tolift the footed legs when the handle is lowered to effective position.

said jack post shoulders,

3. A sadiron body provided with a heating means, a jack post hired to the iron body and having head shoulders, a cross-barabove the.

footed legs when the handle is lowered to efiective position; said spring device acting automati cally to raise the handle and depressthe side legs to a foundation and raise the iron from the foundation.

4. A sadiron body provided with a heating means, a jack post fixed to the iron body and having head shoulders, a cross-bar above the body having footed side legs, a spring device compressed by and between said cross-bar and said jack post shoulders, a handle hinged to said post and operatively linked to the said bar, and manually set means for securing the handle in a lowered position to, and for manual operation of, the iron; said handle operative to lift the footed legs when the handle is lowered to efiective position; said spring device acting automatically to disengage said securing means and raise the handle and depress the side legs to a foundation and raise the iron from the foundation as soonas manual-pressure is released from the handle.
