Parental). 1, g 1936 SELF-LIFTING SADIBON Allen F. Kipper, Glendale, and Louis B. Tuckerman, Los Angeles, Calif., assignors to Continental Fire-Proof Iron Corp., a corporation of Arizona Application July 5, 1935, Serial No. 29,948

17 Claims.

Our invention relates to and has for a principal object the provision of a sad iron, preferably but not necessarily of the electrically heated type, and

provided with means associated with the handle 5 of the iron for automatically lifting the base of the iron substantially above a supporting surface when pressure on the handle is released and for supporting the'iron in raised position when not in use.

10 A more detailed object is to provide a simple,

effective and durable structure whereby the lifting device may be supplied as a part of an iron without materially increasing the cost over the usual type of sad irons, and for reducing the number of parts to a minimum. Other objects may appear as the description progresses.

An important feature of our invention consists in so mounting and forming the lifting means with angularly disposed .arms with interconnecting rounded heel portions whereby when the iron is raised 'or lowered the lifting means will be caused to roll on the supporting surface for the iron and effect a corresponding longitudinal movement of the iron.

We have shown a preferred form of device in the accompanying drawing, in which: v

Fig. 1 is a side elevation of a sad iron embodying our improvements with the lifting device operative for supporting the iron in raised position;

6 Fig. 2 is a similar view of the same with the lifting device arranged for supporting the base of the iron on a suitable surface;

Fig. 3 is a sectional plan of the' same on line 3-3 of Fig. 2; 1 35 Fig. 4 is a rear end elevation of the sad iron; Fig. 5 is a transverse section of the iron handle on line 5--5 of Fig. 1;

Figs. 6 and '7 are transverse sections on lines 66 and 1-1, respectively, of Fig. 2.

40 Our improved sad iron includes a conventional base I and a handle 2 spaced from said base and supported at opposite ends by means of straps 3 and 4. Said straps have vertically formed portions 5 and 6, respectively, which are attached to 45 the ends of the handle 2 by means of screws as at 'l, I, and their lower extremities are suitably attached to the top of the base I by means of screws The lifting device includes an auxiliary handle 9 of channelled cross section adapted to overlie the handle 2, an upper toggle member l and a pair of lower toggle members H, II, which are pivotally connected at l2 and a sp he d od 55 I3 slidably supported in the handle 2 and pivoted tends lengthwise of the handle at l2 to the toggles l0 and l l.

and2.

Handle 9 is pivotally supported on handle 2 at the front end of the iron at l4 preferably by means of an internal channel bar l which is welded at 5 points Hi to the web of the handle S'and ears 5' 'formed on and inwardly turned from the portion 5 of the handle strap3. The'cha'nnel bar l5 exnd is pivotally ogg'le member In 10 normal position,

nds of the toggle :ent the rear end connected at H with the upper so thatwhen the handle B-i's, as shown in Fig. 1, the pivoted members in and II will be .adjj of handle 2. g

Rod I3 is slidable in a bore l8; f: handle 2 and has a. compression spring [9 heldthereon between a nut and the portion 8..of;strap,-4 whereby the toggle is spring urged intoithepb'sltion shown in Fig. 1. Toggle members 1.1 are pivotally held at 2|, 2l, on .opposite sides "of: thiron base I and 0 have arms 2|, 2 l and feet 22,1522, extended downwardly at corresponding angles from their fulcrums 2|, 2|, which, whenjlie handle 2 is released, are swung downwardly into horizontal planes parallel with thebase?! of the iron by the tension of spring [9 and serve to raise the iron into the position shownin-lFig; 2 from a supporting surface 23. Intermediate feet -22 and arms 2| are rounded heel portions 22 =on which the iron rocks when the same-israised and lowered,

in a rolling movement,'so as to reduce resistance and facilitate the operation ofthe lifting means. Y

Portion 6 of strap '4 has an elongated slot 24 therein through which rod I3 is extended and the outer end of said rod is flattened at 25 and has an elongated slot 26 therein for receiving the hinge pin 12, so that when the toggle device is operated the rod l3'will not bind on the strap 4 or the pin !2. Preferably the toggle III is of channelled cross section and is adapted to nest in the channel of member l5 when the handle 9 is depressed, as shown in Fig. 2, and the upper side of handle 2 is provided with a channel 21 which is adapted to receive the member IS in such event.. In operation, it is obvious that when the handle is released the tension of spring l9 will 'draw the toggle joint l2 inwardly to a point adjacent the rear end of the handle and simultaneously depress the feet 22 of the toggle members II, II, so

that the base I -of the iron will be automatically raised above the supporting surface 23, thereby preventing the burning of the cloth on said surface and eliminating the necessity for placing the iron on a plate. as in ordinary cases.

When the iron is grasped in the hands'of a user and pressure is applied to handle 9 said handle is moved downwardly until it embraces the handle 2 of the iron, thereby elevating the feet 22 and lowering the iron base I upon the'supporting surface 23.

The toggle arrangement shown and described provides a minimum range of -movement for handle 9 in raising and lowering the iron and substantially simplifies the operation and use of the iron as compared with other devices for the same purpose. The fulcrum points 22 are so positioned that the iron when raised above the supporting surface 23 will remain in a horizontal position. In order to prevent the iron from remaining in an upright position in the event it maybe dropped on the floor we provide a plate rear end of the base with the floor. raised the heels 22' of the lifting means roll on 30 attached at an end to the rear end of base I by means of a screw or screws 3| and having an outwardly projecting portion 32 so formed that regardless of in what position the iron might light upon the floor it will be restored to the horizontal position shown in Fig. 1 and thereby prevent a fire as a result of the contact of the As the iron is the surface on which the iron rests while the iron moves backwardly until it finally rests upon the surface 23 and the lifts are further elevated to the position shown in Figure 2. When the iron is lowered the heels 22' first engage the surface 23 and roll thereon until the feet 22 assume the position shown in Figure 1, the iron moving forwardly until it assumes a position of rest.

Thus, an iron such as we have disclosed herein is fire-proof and safe, labor saving and durable.
