IRONINGQ-MACHINE.

Specification of Letters Patent.

A lication fil d February 14,1906. Serial No. 300,979.

To all. whom 'it may concern:

Be it known that I, WILLIAM E. ANDREE'I, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Ironing-Machines, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof. i

This invention relates to machines especially adapted for the ironing of shirt cuffs, neckbands, etc.; and its object is to provide a simple and efficient machine for doing this work.

The invention consists in the mechanism hereinafter described and illustrated in the accompanying drawin gs, in which Figure 1 is a detail elevation of the machine, some of the parts being removed; Fig. 2 is a side elevation of the machine, some of the parts being shown in section; and Fig. 3 is a sectional detail of a spreading wedge used in the machine; Figs. 4 and 5 are details of pressure heads; Fig. 6 is a detail vertical central section through one part of the machine; Fig. 7 is a detail side elevation of the machine; Fig. 8 is a sectional detail of the pressure blocks or heads; Fig. 9 is a detail of the pedal mechanism, and Fig. 10 is an elevation of a pair of shield plates used on the machine.

As illustrated the machine is shown as carrying two ironing devices mounted upon a single standard or frame. As these ironing mechanisms are identical in construction but one. will be described.

A standard 15 rises from a'fioor platform 16 and carries at its upper end a cross-arm 17 The ironing mechanisms are supported by the platform 16 and react between it and the cross-arm 17. A steam chest 18 is secured to and depends from the end of the arm 17, its

' lower face being concave and polished to form the irontaken up by the pad to more readily evaporate.

The inner faces 25, 26, of the blocks 19, 20, are flat-' tened and dressed to form bearing surfaces for a wedgeblock 27 entering between them and forming at once the support and spreading device for the pair of blocks. A retractile spring 28 unites the lower endsof the blocks 19, 20, to cause their withdrawal from the'ironing face of the chest 18 as the wedge descends. The polishing surface of the steam chest extends through 33 formed on the standard 15, this arm being in turn supported by an extensible rod 34 pivotally attached at 35 to the upper end of an arm 36 of a bell-crank lever, which is pivoted at 37 to the floor plate 16, the other arm of the bell crank taking the form of a pedal 38. When the pedal 38 is raised the joint at 35 is flexed,

thereby withdrawing the rod 31 and with it the wedgeblock 27 and allowing the collapse and descent of the compressing head comprising the two blocks 19, 20. When the pedal 38 is depressed the members 34 and 36 are brought into alinement, as shown in Fig. 2, thereby forcing up the wedgeby a toggle action. The pedal 38 is raised by means of a sc'cond pedal 39, located beside it and also pivoted at 37, the two pedals resting upon the opposite ends of a rock lever 40, so that as one is depressed the other is raised. I

In order to insure a uniformity of pressurcthroughout. the entire area of the pad 22, means in addition to the wedge-block 27 are provided for raising the compression head, and consist of a rod 41 sliding through brackctnrms 42, 43, projecting laterally from the rod 31 and pivotally attached to the pivot pin 21 which unites the blocks 19, 20 A cushioning spring 44 is interposed between the upper guide bracket 42 and the head of the rod 41, thereby providing a yielding connection between the compression head and the supporting rod. The tension of the spring 44 is regulated by a supplemental spring 45 reacting between the lower face of the bracket 42 and an adjustable collar 46 on the rod 411 This spring is Weaker than the spring 44, but to the extent to which it is compressed by the adjustment of the collar 46 it counteracts the tension of the spring 44.

In order to further adjust the parts relatively to the 'steam chest, the rod 34 is sectional and extensible,

its two members being united by a turn buckle 47.

One or both ends of the compression head may be closed by means of check plates 48, 49, one secured to each of the blocks 19, 20, by means of the threaded rods 50, 51, projecting from a central web 52 of the compression blocks. To the outer ends of these threaded rods are "applied thumb-nuts, as 53. The cheek-plates are further anchored in place by means of a stud 54 screwed into and projecting beyond the end of the pivot 21 upon which they oscillate.

A chain 55 is attached to the head of the rod 41 and to a bracket-arm 5(iprojecting from the cross-member 17 of the standard, such connection being shown as being through the medium of an arm 57 pivoted to the bracket and provided with a laterally projecting arm 58, which is removably secured to the bracket, as by a screw-bolt 59. and may be released for the purpose of increasing the effective length of the chain 55, when the covering pad of the blocks 19, 20, is to be renewed.

The articles to be ironed are applied to the comprt ssion head by withdrawing it laterally from the steam chest 18, the rod 31 swinging about the pivot connecting it with the arm 32, the wedge-block 27 having been first withdrawn. The article having been applied to the cor'npression head, the latter is forced back into engagement with the steam chest, and the pedal 38 being depressed the head .is raised and expanded, compressing the article upon the heated surface.

At (30 is shown an arm projecting laterally from the pedal 38 and interlocking with the pedal 39 for the purpose of limiting the upward movement of the pedal 39.

A work-supporting table 61 is carried by a bracket 62 secured to the standardl5, and cups 63, 64, are shown as suitably carried by the standard as convenient accessories to the ironing operation.

Fig. 2 shows the machine as especially adapted for the ironing of shirt cuffs, the ironing surfaces being of suificient width for use in connection with these articles. I

In Figs. 6 and 7 the device is shown as adapted for the ironing of neckbands, differing essentially from the cuff machine only in that. its ironing surface is of less width.

Steam may be led to the steam chests 18 through pipes, as shown at 65, and the water of condensation led therefrom through pipes as shown at 66.
