ALLEN ANDERSON AND MAX DECKERT, OF CHICAGO, ILLINOIS, ASSIGNOBS TO WHITE BEAUTY ELECTRIC 00., OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

ELECTRIC FLATIRON.

Application filed November To all whom it may concern.

Be it known that we, ALLEN ANDERSON and MAX DECKERT, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois have invented a certain new and useful Improvement in Electric Flatirons, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

Our invention relates to electric flat irons and has to do more particularly with the provision of an improved structure havin certain features of advantage hereinafter more particularly pointed out in the specification and claims.

In connection with an electric or other flat iron it is very desirable the construction be such that the iron may be readily cleaned so as to not only resent the best appearance, but also keep from soiling the clothes. To this end we have provided a pressure plate or Weight member for electric irons having a smooth exterior and covered with baked enamel, preferably white. Another feature of our invention is an improved and simplified construction in whlch an air ventilating chamber is provided at the terminal portion thereof, thereby preventing a burning out of the electrical conductors as has heretofore occurred.

For a better understanding of our invention reference is to be had to the accompanying drawin in which- Flg. 1 is a si e elevation of an electric flat 11011, partly in section for the purpose of illustrating the ventilating chamber in the pressure plate; Fig. 2 is a. rear or left end view of Fig. 1; and

Fig. 3 is a plan View of Fig. 1, with the handle removed.

Referring now more in detail to the construction as illustrated, we have shown an electric flat iron havin a pressure plate or weight member 5 pro erably made of cast iron and secured to a nickle plated baseplate heating element 6 by means of bolts -8 which pass through the lower extension on the handle 9 and then into the heating element or lower plate 6 so as to hold 7, 1921. Serial No. 513,549.

which the electrical conductors 10 extend into direct connection with the heating element 6. This passage is preferably in the nature of a ventilating chamber 11 covered by a perforated metal plate 12 secured to the pressure plate in a suitable manner and preferably by an extension 13 which is held between the handle and pressure plate. An opening 14 is provided in the plate 12 above the chamber 11 and through which the conductors 10 extend. By means of this chamber 11 the portion of the iron throughwhich the conductors 10 extend is maintained cool so that the insulated covering for these conductors is not burned or charred as frequently occurs in the ordinary iron.

By passing these conductors directly down to the heating element where they are suitably secured to extensions 15 of the heating element, we have eliminated the expensive terminal connections frequently employed, thereby providing a simple and cheap construction. The great objectionsto such prior structures is that of the burning off of the conductor insulation. By means of the ventilating chamber provided in our present invention, the conductors are maintained cool at the connected ends and suitably protected by the perforated cover over this chamber.

For the purpose of providing a rest for the iron whereby it may be supported so as not to char or burn any of the surrounding objects, we provide a pair of lugs 16' 17 extending from the rear end of the pressure plate and alongside of the ventilating chamber. Thus, the iron may be supported upon these lugs and the rear end of the handle 9.

As referred to above, it is very desirable that an electric iron be kept clean and free from dirt, so as not only to present a. pleasing appearance, but to (prevent soiling of the clothes. To this en able layer of enamel to the outside of the pressure plate using a heat roof covering. For this purpose we prefera 1y use a white porcelain enamel baked onto the pressure plate thereby providing a most lsanitahy looking iron and one on which any dirt will readily. show, and may be easily cleaned.

What we claim as new and desire to secure by United States Letters Patent is:

1. In an electric flat iron, a base-plate heating element, a. solid pressure plate havwe apply a suit- 7 ing a ventilating or cooling chamber opening out ofthe rear end thereof, through which the electrical conductors extend out of contact with the pressure plate body to insulate them from the heated pressure plate above the heating element.

2. In an electric fiat iron, a pressure plate having a ventilating or cooling chamher at the rear end only thereof through which the electrical c-ondu'ctors extend. and a perforated closure plate for said chamber for heat-insulatinglv supporting the electrical conductors.

3. In an ele: tric flat iron, a pressure plate a base-plate heating: element secured to the bottom of the pressure plate, and a ventilating chamber in the rear end of the pressure plate through which electrical conductors may extend for connection with the heating '29 element, said chamber acting to insulate the plate heating element having a cooling chamber recessed in the rear end thereof positionedabove the conductors from the base-plate heating element. and'through which said conductors extend, and a sheet-.

metal plate mounted over said cooling chamber supporting said conductors.

In witness whereof We hereunto subscribe our names this 18th day of October, A. 1921.

ALLEN ANDERSON. MAX DECKERT.
