HEATING DEVICE Filed March 22, 1954 g9 VZ m Patented Nov. 2, 1937 UNITED STATES PATENT OFFICE HEATING DEVICE Anna M. Haas, Chicago, Ill.

Application March 22, 1934, Serial No. 716,791

1 Claim.

The invention relates to heating devices and more particularly to electric irons.

It is an object of the invention to provide a heating device which is adapted for the ironing and steaming of fabrics of tubular shape or arranged in rufiies which the ordinary fiat iron cannot be applied to.

It is a further object of. the invention to provide a heating device where the iron proper may be readily exchanged for an iron of more suitable shape to meet particular requirements in the ironing or pressing of delicate fabrics, ruflles, sleeves and the like.

It is an object of the invention to provide an iron of egg shape form and means for supporting such iron with its longitudinal axis in horizontal position.

To the accomplishment of these and other equally important objects, the invention is described in the following specification, particularly pointed out in the claim forming a part thereof and illustrated in the accompanying drawing, in which:

Fig. 1 is a perspective view of the iron constructed in accordance with my invention.

. Fig. 2 is a longitudinal section through the iron proper.

Fig. 3 is a section on the line 3-3 of Fig. 2, and,

Fig. 4 is a side view of a modified form of the iron.

Referring to the several views in the drawing, i designates a base plate from which arises at the center thereof a post I l equipped at the upper end with a threaded socket of standard construction. The iron proper generally designated by M is in the form of an oval comprising an upper section l5 and a lower section I6, the line of intersection being along a horizontal plane and the lower section l6 being provided with a rabbet l1 into which fits a lip I8 projecting from the upper section IS. The two sections of the iron have a press-fit relation and when assembled form a unitary part. The two sections are also held together by screws l9 and 20 as is obvious from Fig. 2.

The lower section I6 is formed with atubular extension 30 to which is secured a contact I2 and a contact I3. The contact I2 is formed with screw threads to be threaded into the upper end of the post II.

A horizontal partition 2! divides the inner chamber of the iron in an upper and a lower chamber and closes an insulated tract 22 provided at the inner side of the upper section I! for the reception of aheating element 23 whose ends are connected by wires 24 and 25 to the annular contacts I! and IS. The partition H is formed with a central aperture 26 for the passage of the wires 24 and 25.

In use the iron is connected by a cord 21 and a plug 28 to a source of electrical energy whereby theheating element 23 is energized so that the iron proper I4 is heated.

A fabric such as 29 which is provided with ruflies is drawn around the iron l4 whereby when the heat acts on the fabric the latter is steamed or pressed.

In the case of having delicate materials where ruiiles are present the iron shown in Fig. 4 and generally designated by 3| is used which is formed like a projectile and is composed of anupper section 32 and alower section 33 secured together in the same way as the iron l4 and having also a tubular extension 34 which is provided with aplug contact 35. Thus in the case of small ruffles or pleats the iron I4 is removed and the iron I3 is put in place on the post H. The fabric is then drawn across the iron 3i and exposed to the influence of the heat emanating therefrom to obtain a pressing or steaming effect.

It is obvious that the shape of the irons and the method of supporting them are suitable for" the pressing of sleeves, pleats, ruiiles and especially of materials which are delicate or of. a frangible nature.

While the drawing shows preferred embodiments of the invention, numerous changes and variations may be made without departing from the spirit of the invention. I, therefore, do not limit myself to/details of construction, but claim my invention ias broadly as the state of the art permits.

I claim:

In combination with a base plate, a post integral therewith and upstanding therefrom, a socket at the upper end of said post, a heating body of elliptical form constructed with a ball shaped extension at the end, and a. plug secured to the underside of said heating body for removable attachment to said post, said heating body having the heating element adjacent to its pper wall and screened from the lower wall.

ANNA M. HAAS.
