Specification of Letters Patent.

Patented Mar. 1, 1921.

Application filed May 18, 1917. Serial No. 16,9,474.

To all whom it mag concern Be it known that I, IVILLIAM EDWARD Anemia, a citizen of the United btates, residing at Chicago, in the county of Cook and State of'Illinois, have invented certaln new and useful Improvements in Pressing- Machines, of which the following is a specification.

This invention relates to press ng machines such as are used for presslng garments, cloth, woven fabrics or the like. The object of the invention is to provide an 1mproved pressing machine embodying relatively movable bucks or pressing members suitably padded, as is usual, together wlth means for applying moisture to the garment to improve the pressing operation, and means for quickly drying the garments being pressed and the pads of the pressing members, to thereby enable garments to be pressed and dried more quickly, to keep the pads dry and efficient, and to avoid spotting or injuring the garments being pressed by moisture in the pads. A further object of the invention is to provide an improved pressing machine in which the garments being pressed and the pads are dried by a current of air passed therethrough, preferably under pressure, and said air being heated to produce maximum drying effects.

Further objects of the invention are in part obvious and in part will appear more in detail hereinafter.

The invention comprises the'pressing machine, hereinafter described and claimed.

In the drawings, which represent one embodiment of the invention, Figure 1 is a side elevation, showing the press closed; Fig. 2 is afront elevation, partly broken out and in section; and Fig. 3 is a detail section, showing the steaming device in the stationary pressing member.

, The pressing machine shown in the draW- ings comprises a suitable frame 1 having a front standard 2 supporting a stationary lower pressing member or buck 3,. and a rear standard 4 to which is pivoted a swinging arm or lever 5 supporting the movable upper pressing member or head 6 for cooperation with buck 3 in the usual manner. The shape or configuration of the head or buck to accommodate garments of different kinds may obviously be varied within wide limits. The head is normally held elevated by a spring 7 and is depressed into pressing relation with the buck by operation of a foot treadle 8 connected by a link 9 to a lever 10 which is connected by a link 11 to operate two toggle links 12. 13 indicates a release treadle having an arm 14 extending under the treadle 8 for elevating the same to break the toggle.

The upper pressing member is heated by steam admitted to its hollow heating chamber 15 through a supply pipe 16. Its lower face is smooth and uninterrupted, but is covered with the usual padding or press cloth indicated at 17.

The buck 3 isof complementary form to the head 6, its upper surface being likewise provided with padding 18 lying over the perforated plate 19, the perforations in which communicate with a hollow chamber 20 extending over substantially the entirearea of the buck. Beneath the plate 19 is a horizontal wall 21, dividing the space within the buck into two chambers, one the chamber 20 before referred to, and the other a chamber 22 communicating with a suitable source of heating medium, by a pipe 23. The garments to be pressed may be moistened in any suitable manner, such as by steam supplied to the upper surfaceof the garment or from the lower buck, as desired. As illustrated,the horizontal wall 21 is provided with passages 24. therethr'ough controlled by a valve 25 seating upwardly and held-to its seat by the spring '26. The valve stem 27 passes down through a stuffing box 28 to a lever 29, by depressing which the valve may be opened to permit steam to How from the live steam chamber 22 throughpassages 24 to chamber 20, and thence .through the perforations in plate 19 and through the padding 18 to the garment. When lever 29 is released valve 25 closes and cuts off the supply of steam to chamber 20.

Chamber 20 not only is the steaming chamber in the buck, .but also is the chamber through which air is supplied to the pads for drying the same and for also drying the article being pressed. For this purpose chamber 20 communicates by way of a passage 30 with a pipe 31 communicating with as connected to the releasetreadle 13, which is provided with an arm 37, connected bya link 38 to one arm of a bell crank lever 39,

the other arm of which is connected through a yielding spring 40 to the valve stem. Consequently, whenever the release treadle is depressed to open the press the air pressure is turned into the chamber 20. This will occur simultaneously with the opening movement of the press and at a time when the steam valve 25 isv closed. The air pressure may be held on as long as desired.

With the arrangement described garments ma be pressed and dried more quickly than wit press'es as heretofore constructed. The buck is heated by the live steam constantly present in chamber 22. Therefore, the air supply for drying the garments passes through a heated chamber and its temperature is elevated considerably above the atmospheric. This materially improves the ability of the moving air to absorb moisture from the padding of garments thereon.

- Moreover, the air pressure has a distinct advantage over suction or vacuum, as-usually employed, in that it keeps the padding loose and flutfy, so that it is not so liable to mat down. The pads are always substantially dry, as a result of which the press may be used for pressing garments which otherwise would be spotted or damaged by the moisture of the pads. Moreover the passage of hot air through the padding maintains the pad in a hot condition, as distinguished from the cooling of said pad which occurs when cold or atmospheric air is drawn down through the. pad, as where a vacuumis employed. Other advantages of the invention will be apparent to those skilled in the art.

\Vhat I claim is 1. A pressing machine, comprising relatively movable cooperating upper and lower pressing members, one of which is provided with a foraminous pressing plate forming one wall of a shallow chamber, the opposite wall of said chamber forming-a partition between said chamber and a second chamber, means for supplying steam to said second chamber, means for supplying compressed air to said first chamber, and means controlling the flow of steam from the second to the first chamber.

2. A pressing machine, comprising relatively movable cooperating upper and lower pressing members, the lower pressing memher being hollow and provided with an inner horizontal wall forming a partition between a lower and a shallow upper chain ,ber therein, a :t'orammous pressing plate near to and parallel with said partition and forming the upper wall of the shallow upper chamber, means for maintaining a supply of steam in the lower chamber to heat the lower pressing member, valve means controlling the flow of steam from theheat ing chamber to the upper chamber and thence through the foraminous plate for moistening the garment, and means for producing flow of air tothe upper chamber and thence tl'irough the foraminous plate for drying the garment.

In testimony whereof I afiix my signature in presence of two witnesses.
