ELEGTR IC IRON Filed Dec. 9, 1935 ATTORNEY UNITED STATES PATENT oFFlcE ELECTRIC IRON Alfred C. Schmidt, Teaneck, and Charles W. Bruger, Union City, N. J.

Application December 9, 1935, Serial No. 53,572

2 Claims.

T'his invention relates to improvements in electric sadirons or fiatirons for use in the home or by tailors or the like, and it is the principal object of our invention to provide an electric iron having its heating surface and vthus its smoothing surface greatly enlarged by the arrangement of rollers which are rotating in suitable chambers formed in the body of the flatiron, and which have their outer mantles or peripheries ilush with the smoothing or bottom face of the iron and which are substantially conical in opposite directions.

Another object of our invention is the provision of an electric ilatiron equipped with means, such as for instance rollers, for greatly facilitating its operation notwithstanding its somewhat increased weight, and which are so closely arranged to the walls of their chambers as to present a nearly uninterrupted surface with the bottom of the iron.

Still another object of our invention is the` commonly used irons by virtue of the increase in the ironing surface by the rollers and the ready distribution of the heat from the interior through the chambers opening towards the ybottom of the iron, and the increase in the length of the resistance coil wires which are guided about the rollers.

A still further object of our invention is the provision of an electric sadiron the rollers of which may be replaced by balls or similar bodies and which is comparatively simple in its construction, yet durable and highly eiiicient in use.

It is furthermore also one of the objects of our invention to provide an electric iron, the heating element of which is guided closely about the rollers in a novel and improved manner to positively heat the smoothing surface of the iron and its rollers, and thus greatly increase the efliciency 55 teria] part of this disclosure:

considerably greater amount of heat than the.

(Cl. 21S-25) Fig. l is the side elevation of an electricilatiron constructed according to our invention, partly in Fig. 2 is a bottom plan view of the same seen in the direction of the arrows on line 2-2 of Figure l.

Fig. 3 is a cross-section on line 3 3 of Figure 1.

Fig. 4 is a bottom plan View of a modiiled form of our sadiron.

As illustrated in Figures 1 to v3, a ilatiron of any well known type including its body I0 and handle II suitably connected to the body, and contact socket I2, has its bottom or ironing face I3 or plate provided with openings I4, I5 through which are visible the mantles or peripheries of, rollers I6, I'I substantially flush with the bottom' I3 of the iron. The rollers rotate ori-the shafts I8, I9 suitably journaled in bearings 2|, 22 within the body of the iron, and adjustably held by means of the

screws

23, 24 or the like.

The resistance wire or coil of the heating element 25 surrounds the rollers in close proximityv to the same, and its terminals are connected in the well known manner to suitable contacts to Y be connected by a switch or plug entered into socket I2.

In the modified form of our invention illustrated in Figure 4,

rollers

26, 21, 28 are of various sizes and are arranged in staggered relation to one another; they may evidently be replaced by balls, casters or similar devices without departure from our invention. The resistance coil wire 29 also in this form surrounds the rollers in close proximity thereto in the body 30 yof the iron.

The operation of our device will be entirely clear from the above description by simultaneously referring to the drawing, and it will be evident that the rollers with the smaller end of some -of them and with the larger end of the other rollers mounted nearer to one side of the iron than to the other side will thus produce a conical effect and will facilitate the guiding of the iron over a smooth surface and effectively atten out all wrinkles, etc., so that even a child may be able to handle the iron; the heating element will allow the use of current to develop the greatest possible amount of heat which in combination with the increased ironing surface will beneilt the fabric to be ironed to the greatest extent.

It will be understood that we have disclosed the preferred forms of our invention only as a few, examples of the many possible ways to practically construct the same and that we may make such changes in the general arrangement of the iron and in the construction of its minor details as come within the scope of the appended claims without departure from the spirit of our invention and the principles involved.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is:

1. An electric iron having openings in its bottom and comprising rollers of various sizes and located with the smaller ends of some of the rollers and with the larger end of the other rollers nearer to one side of the iron than to the other side for producing a conical effect, arranged in staggered relation to one another and extending into the openings in the bottom of the ironing surface of the iron, and a heating element surrounding said rollers in close proximity thereto.

2. An electric iron having openings in its bottom and comprising a pair of tapered rollers with the smaller end of one of said'rollers and the ment surrounding said rollers in close proximity 10 thereto.
