IRONI'NG SHOE. 4

Application filed June 30, 1924. Serial No. 723,139.

5 Long Island, in the county of Queens and State of New York, have invented certain new and useful Improvements in Ironing Shoes, of which the following is afull, clear, concise, and exact description.

This invention relates to shoes for power driven ironing machines. More specifically, it refers to an electrically heated ironing shoe which is particularly well adapted for use in an ironing machine of thetype disclosed in Patent 1,526,374 granted totnie February 17, 1925, which discloses an ironing machine in which a plurality of gas heated shoes .are adapted to cooperate with their respectively associated ironing rolls for ironing articles of different characters.

The object of this invention is to improve the construction of such ironing shoes.

In accordance with this invention the ironing shoe which. coacts with the power roll comprises a metallic member carrying, a heating unit-,a switch being mounted on the shoe which contains terminals of the wires of the heating elements to control the current for heating the unit.

More specifically the shoe comprises a plano-concave metallic member, preferably a casting, supporting on its plane face the electric heating unit and its opposite concave face being adapted to cooperatew th 85 the power roll, this shape providing for heating the effective portion of the shoe umformly and economically at the requlred temperature.

Other features of this invention and advantages will appear from the followlng description and by the claims appended thereto, reference being had to the accompanying drawings in which:

Fig. l is an assembly view of the ironing shoe with portions of the heating unit and housing cut away.

' Fig. 2 is a sectional view of the shoe taken up roximatelj on line 22 of'Fig. 1 and l e iting in the direction indicated by the ,ar-

rows; and

Fig. 3 is a view similar to that of Fig. 2

showing an alternative arrangement of the heating elements in the shoe.

Similar reference characters refer to similar parts throughout this, description.

The ironing shoe of thisinvention' preferably consists ofia lano-concave shaped casting 10, the concave side of which is adapted to'cooperate with a power driven roll 12 which is generally covered with a pad 13 as shown in Fig. 2. On the plane surface 14.- of the casting -1O is mounted a unit made up of a series of electrical heating elements which preferably consist-of two parallelly disposed insulating strips 16 and 17 on which the metallic ribbons 15 and 18 are-wound as shown in Fig. .1. The strips. 16 and 17 are held in spaced relation by means of insulating strips 22 and 23 and the whole held in a metallic frame or envelope 24. This frame 24 is held securely against the plane surface 14 cf the casting 10 by means of a metal a plate 25 which is screwed to the casting by means of a number of screws 26, 27, etc., thus permitting the removal of the heating unit for inspection or repairs.

An arcua'tedflange 29 inwardly lined with a strip of insulating'material 30 is secured along the edge of the casting 10 and cooperates therewith to form a housing adapted to be filled with asbestos cement or any other like insulating material in order to confine the heat to the effective portion of the shoe.

The ends of the conducting ribbon or coil 15 are connected to the ends of wires 33 and 34 by means of screws 20 and 21 and the ends of the coil 18 are'connected to the terminal of wires 35v and 36, by means ofscrews 20 and 21 respectively. The opposite ends of wires 33, 34, 35 and 36.are each connected to a switching device 37 which is disposed in a convenient place with reference to the operator of the machine. This switching device is mounted in a housing 38 preferably made integral with the arcuated flange-29 and is provided for controlling the heating ,ele-

ments'15 and 18 through the provision of a suitable multiple switching mechanism not shown. An insulating bushing 39 securely arranged in the housing 38is provided for protecting and for holding the cord 40 in position.

The lugs 44 shown in Fig. 1 are preferably made integral with the casting 10 and are provided for pivoting the shoe on the machine in the manner described in the copending application above referred to.

In the modification shown in Fig. 3 the heating element is held securely in the convex side of the casting 10 by means of a plurality of arcuated clamps 42.

From the foregoing it will be seen that the present inventionprovides an improved shoe which has the-.advantages 0f- "1. Eliminating all exposed wires except the conductor cord.

2. It makes the shoe a complete unit.

3. It doesnot interfere in any way with the tipping back of the shoe for cleaning or prising a metallic member, an electric heating element mounted on said member, a. controlling switch mounted on said shoe, and a conducting cord connected to said switch.

2. A ironing shoe comprising a piano concave shaped metallic member, and a heating element mounted on the plane surface of said member.

3. In combination, an. ironing shoe comprising a metallic member, independent electric heating elements mounted on said memher, and a manual switch mounted on said shoe for independently rendering eflecti ve the heating elements.

4. An ironing shoe for a power driven ironing machine comprising a plano-concavc shaped casting, anarcuated flange secured on said casting and arranged to form a housing adapted to be filled withinsulating material, a heating unit consisting of a plurality of independent coils in said housing,

and a switching device mounted on said flange to render said coils effective with respect to, said casting singly or collectively.

In witness whereof, I hereunto subscribe my name this .CHARLES E. REDDIG.
