SHOE FOR IRONING MACHINES Filed June 8, 1934 2 Sheets-Sheet 2 Patented Dec. 17, 1935 UNlTED STATES SHOE FOR IRONING MACHINES William J. McCaugha-n, River Forest, 111., assignor to Electric Household Utilities Corporation, Cicero, Ill., a corporation of Illinois Application June 8, 1934, Serial No. 729,551

13 Claims.

My invention relates to improvements in ironing machines and has more particular reference to improvements in the ironing shoe which carries the heating element and which is usually movable toward and from the other ironing element in the form of a padded roll.

One of the objects of my invention is to provide an ironing element or shoe for ironing machines, which has a flexible ironing surface adaptable to variations in thickness of the material being ironed.

A further object is to provide an ironing element or shoe for ironing machines, in which sections of the ironing surface are relatively movable to enable folds to be made in the material being ironed, without raising the other portions of the ironing surface away from the thinner or unfolded portions of the material.

Other objects of my invention will appear hereinafter.

Referring to the accompanying drawings which illustrate one embodiment of my invention,

Fig. 1 is a general view in elevation of the upper portion of an ironing machine, showing the roll and ironing shoe mounted thereon in operatin relation;

Fig. 2 is an enlarged longitudinal sectional view of the shoe, with the roll in elevation, taken substantially on the line 2-2 of Fig. 3;

Fig. 3 is an enlarged transverse sectional view through the shoe and roll, and taken substantially on the line 3--3 of Fig. 2;

Fig. 4 is another transverse sectional view of the shoe and roll, taken substantially on the line 4-4 of Fig. 2; and

Fig. 5 is an enlarged longitudinal detail section illustrating the action of the sectional ironing plate with respectto a folded piece of material being ironed;

In the drawings, a table or stand A is illustrated, upon which the standard B is mounted. The standard supports the ironing elements C and D and contains the driving or actuating mechanism therefor. In ironing machines of this character, the standard B is usually positioned at one end of the ironing elements and has a horizontally projecting shaft upon which the roll C is supported and by which itis rotated. The standard B also carries a horizontally extending rock shaft I, at the outer end ofwhich a supporting tion of the shoe D. The roll C is in the form of an elongated cylinder and is usually provided with a padding 4 on its surface.

The ironing shoe D is made in the form of an elongated, relatively thin structure, extending 5 substantially the length of the roll and transversely curved to conform to the curvature of the roll with which it cooperates. This shoe comprises a curved ironing surface plate III, a heating element I l a cover member I2, and an elongated l0 rigid backing member or bar l3 which serves as a mounting for the other parts of the shoe. The ironing plate I0 which provides the ironing surface contacting with the roll or the material between the roll and the shoe, is made up of three 15 separate sections I5, I6 and I5, although the number of sections may be varied as desired. These sections are all relatively movable with respect to each other. Normally, however, their ironing surfaces are all maintained in the same plane; 20 but when varying thicknesses of material are passed between the roll and the shoe, the sections of the ironing plate yieldably adapt themselves to the varying thicknesses of the material ironed. For instance, as illustrated in Fig. 5, the material 25 I1 passing between the end section and the roll is of greater thickness than the portion between the remaining sections and the roll, due to folding or other conditions which arise in the ironing operations. In this case the end section I5 of the 8d ironing plate yields to the folded or increased thickness, but the other sections remain in ironing relation to the other portions of the material and the result is that the pressure is substantially uniform throughout the area of the piece being 35 ironed, and all portions of the material are ironed.

As shown in Fig. l, the several sections of the ironing plate are parted or separated on diagonal lines l9 angularly arranged with respect to the direction of movement of the material being ironed, and the purpose of this arrangement is to prevent the material from entering the space between the sections, which would be the case if the parting lines were arranged in a circumferential direction parallel to the line of movement of the material between the shoe and the roll.

The heating element II extends substantially throughout the length and width of the ironing 1 plate, and is positioned betweenthe ironing plate element will accommodate itself to the relative movement of the piate sections. The sections of theheating element are connected by flexible conductors 20. The heating element may be of any suitable type for the purpose. In the present structure, each section is encased within a metal housing 2| which extends throughout the area of the section and has its margins 22 turned over the edges and bearing against the inner face of the plate section, thus forming a rigid, protecting structure for the heating element.

All of the sections of the ironing plate have studs secured to their rear faces and extending through the backing member or supporting bar l3. The intermediate section l6 of the ironing plate is rigidly mounted with respect to the supporting .bar, and the studs 25 therefor are secured to the backing member l3 by jam nuts 26 threaded on the studs and clamped against opposite sides of the bar. The outer nuts 26 also serve to clamp the supporting bracket 3 to the bar, as shown more clearly in Fig. 2. The outer or end sections l5 of the ironing plate,however, are movable relatively to the bar I3, and the studs 21 therefor extend through holes 28 in the backing member 13 sufficiently large to permit free movement of the studs therein. Coil springs 29 are positioned in sockets 30 in the inner face of the backing member, and these springs bear against the heating element housing to yieldingly make only the end sections of the ironing plate yielding with respect to the increased thicknesses at the margins of the pieces. It is obvious, however, that if desired the intermediate section l8 of the ironing plate may likewise be made yielding, in the same manner as the end sections, if desired.

It is thus seen that the ironing shoe, instead of being rigid throughout its length, is flexible by virtue of the resiliently mounted sections, and is therefore adaptable to the ironing of wide expanses of material having different thicknesses, and that the whole expanse of the material will be ironed irrespective of these varying thicknesses. A shoe of this type is therefore particularly adaptable to the ironing of folds, plaits, and the like, in the material being ironed.

The whole back ofthe shoe is protected by the cover plate l2 which extends the length of the shoe and is curved transversely to correspond therewith. The cover is formed with a channel for the supporting bar I3 and is held in position by the studs 25 and nuts 26 thereon.

It is to be understood, of course, that the construction, operation and arrangement of the parts may be changed without departing from the scope and spirit of the invention and I contemplate such changes as fairly fall within the scope of the appended claims.
