IRONING MACHINE STEAM IR-EMOVER.

Application filed May 22, 1925. Serial No. 32,161.

This invention relates to an ironing machine of the mangle type in which the articles in a more or less dampened condition are fed across a suitable supporting table and upon a rotary feed roll and thence against a heated ironing shoe which is movsired temperature of the ironing surface" whereby the heat imparted to the articles in transit across the ironing face converts themoisture of the articlesinto steam more or less of which escapes into the room or condenses upon the surface of the articles, both of which results are objectionable, both from a sanitary point of view and also by reason of the fact that the steam condensing on the articles leaves a certain amount of moisture therein following the ironing operation.

The main object of the present invention is to provide, simple and eflicient means for progressively removing the steam and 111015- ture from the articles as they feed across the ironing surface and thereby to "render it free from the objectionable results previously named and at the same time to cause a more rapid drying andconsequent fixingof the shape of the articles during the ironing op- 5 eration as they emerge from the machine.

Another object is to provide motor driven means mounted on the frame of the machine for operating thefeed roll and also for operating a suction pump for withdrawmg the steam and ironed articles thru the ironing shoe.

Other objects and uses relating to specific parts of the machine will be brought outin the following description.

In he drawings: i Figure 1 is a rear elevation of an ironmg machine of the mangle type embodying the various features of this invention. Figure 2 is an end view, partly in section, of the same machine.

As illustrated this machine comprlses a main supporting framehaving a base hsupportedby suitable casters --2 and carrying an upright standard 3 adapted to receive and support a main feed roll 4., a

return plate 5- and ironing shoe 6, together with a feed table 7 and various other moving parts hereinafter described.

An electric motor 8 is mountgd a suitable casing or housing 9 base 1 with its armature shaft in a sub.- stantially horizontal position and extended thru one end of the case for receiving and supporting a pulley 10- and a pump im- The pulley 10 is connected by a belt 12-- to a relatively larger pulley i3 on a worm shaft-14+ which is journaled in suitable bearings on the upright standard 3 to revolve about a horizontal axis parallel with the motor shaft.

The shaft 14- is provided with a worm 15 meshing with a worm gear 16' which,- together with a relatively smaller gear 17 is mounted upon a horizontal 18 to a suction chamber Q3 in the 1ron1ng shoe 6 and its pressure side provided with an outlet 24. adapted to be connected to any suitable. waste pipe, .not shown.

The suction chamber 23 in the ironing shoe -6 is provided'with one or more rows of. restricted openings or apertures 25 extending thru the ironing face which is adapted to engage the articles as they are fed rearwardly and downwardly by the feed roll or drum .4.

The ironing shoe '6 is also provided Within on the with a heating chamber '-26-- in which is placed a gas burner -27 or other suitable heating device capable of maintainmgthe ironing surface of the shoe at the deslred temperature. The heating chamber -26- and its burner -27 extend practically the entire length of the shoe 6-- except that the ends'of the chamber are more or less closed for retaining the heat of the burner 1 therein, said heating chamber being also extended transversely the greater portion of the width of the shoe and wholly above the suction chamber -23 which latter with the apertures 25 are arranged near the lower end of the shoe so as to act upon the articles after they have traversed the greater portion of the ironing surface.

The ironing shoe is preferably concavoconvex in cross section with its concave side of slightly greater radius than that of the drum 4 so that the articles may readily enter between the upper edge of the ironing surface and periphery of the roller -4- and gradually be impinged against 'said periphery when the shoe -6 is in its ironing position.

The lower edge of the ironing shoe -6 is secured to one arm of a bell-crank lever -28 which is secured to a horizontal rock shaft -29 on a longitudinally extending arm -30 of the main supporting frame and has its other arm extended rearwardly and slotted to receive an upright rod -31-- which is carried by a pedal-operated lever -32 carrying a pedal 3.

A coil spring -34.- is interposed between a shoulder 35- and the rearwardly ex tending arm of the bell-crank lever --28 for rocking said bell-crank lever and ironing shoe 6 carried thereby to its closed position against the articles on the periphery of the drum 4 with a yielding pressure. The table 7- is supported on the frame of the machine with its upper face in a horizontal plane above the axis of the drum 4 which is rotated in the direction indicated by arrow -m, Fig. 2, to carry the articles from the feeding table -7 into contact with the ironing face with the shoe --6-.

It is evident, however, that the drum 4.- and ironing shoe 6 may be operated by any suitable mechanisms without departing from the spirit of this invention which is directed more particularly to the means for withdrawing steam and moisture from the article while the latter is in transit across scribed, a horizontally extendin the ironing face of the shoe in combination with the means for heating the shoe.

Operation.

Assuming that the feed roll -4 is being rotated by its driving mechanism and that the ironing shoe 6 is heated to the desired temperature by the burner --27- or equivalent heater and that the pump impeller -11 is also being rotated by the motor 8-, then as the articles are fed by hand across the table 7-- they are picked up by the feed roll -4- and carried rearwardly to the ironing shoe 6 which is then pressed forwardly toward the rear face of the feeding roll and against the articles carried thereby for ironing purposes.

As the ironed articles travel across the ironing face of the shoe -6-- they are brought into registration with the suction passages -25 and subjected to the suction produced by the pump impeller -11- thru the conduit -22 resulting in the withdrawal of any steam or moisture of condensation which may be present in the ironed articles as they traverse the apertures Q5- and expelling such steam and moisture thru the outlet -2lto the atmosphere or preferably to a waste pipe, not shown.

WVhat I claim is:

In an ironing machine of the character dcfeed roller, a feed table extending lengthwise along the front face of the roller with its upper surface in a plane above the axis of said roller, a lever pivotally supported in a plane below the roller, an ironing shoe mounted on the lever in a vertical plane at the rear of the lever pivot to extend along the rear side of the roller and movable toward and from said roller as the lever is rocked in reverse direc tions, said ironing shoe havin a heating chamber and a suction chamber lietween the heating chamber and pivot of the lever, said suction chamber having perforations extending through the ironing face of the shoe, means for rotating the feed roller, a suction producing device, a flexible pipe connection etween the suction producing device and suction chamber of the shoe, and pedal operated means for operating said lever to move the ironing shoe into pressing co-action with the feed roller.

In witness whereof I have hereunto set my hand this 14th day of May, 1925.

PETER GELDHOF.
