16 Claims.

The present invention relates to a garment pressing apparatus, of the type employed in tailoring shops, cleaning and pressing establishments, clothing manufacturing concerns and the like, for

. pressing mens and womens outer garments.

A primary object of the invention is to provide animproved apparatus for effectively applying uniform pressing pressure to the garment, as distinguished from conventional machines wherein the degree of pressure applied varies widely throughout different portions of the garment,

depending upon the thickness of the material at different points.

Another object of the invention is to provide,

` vin combination with the means for applying uniform pressure, improved means for heating, mois- 'tening, and drying the garment, before, during,

and" after the pressing operation.

Another object of the invention is to provide improved means for subjecting the garment to the `influence of steam, to moisten and soften the fibers of the fabric, thereby to condition them for shaping or forming, under the influence of heat and pressure, applied uniformly to the garment surface.

Another object of the invention is to provide improved means for causing a flow of drying air through the garment, after the pressing operation, to remove the moisture and thereby to dry and set the garment in the pressed condition.

Other and further objects and advantages of the invention will be apparent from a consideration of the following description of the specific embodiment, shown diagrammatically for purposes of illustration in the accompanying drawings and described below.

In the drawings: l

Figure 1 is a somewhat schematic or diagrammatic view, in side elevation of an apparatus embodying the invention;

Figure 2 is a cross-section through Vthe head and -buck with the press in closed position;

.pervious, fabric covering I5, as is well understood in the art. The buck pad may be consuitable material.

structed in accordance with the disclosure of the copending application of Reiss et al., Serial No. 740.766, filed April l1, 1947, now Patent Number 2,490,981issued December 12, 1949, and reference made to that application for a description of a preferred arrangement of parts. The buck may be of any suitable shape or contour, depending upon the use to which the apparatus is to be put, and includes a steam heating jacket space I6, supplied with steam independently of the other steam connections hereinafter described.

The interior space I3 of the buck may be supplied with steam by a valve I'I connected by a link I8 to a pedal I9, so that a garment placed on the buck may be steamed and moistened, by thelow of steam through the perforated plate I4 and the Vpervious cover I5.

The space i3v in the buck is also in communication through a pipe 20 with a source of vacuum under the control of a valve 2| connected by a link 22 to a suitable pedal I9'. Atmospheric air thus may be drawn through a pressed garment on the buck to remove moisture therefrom, to dry and set the fibers.

The press head I2 may be mounted on the forward end of a weighted lever arm 23, pivoted at 2li to the machine frame 25 and connected by

toggle links

26, 2l, 28, and 29 and a drag link 3l! to an operating pedal 3|. Since arrangements of this kind are well understood and are inwide use at the present time on presses of the Hoffman type, they need not be further described.

The press head i2 has an interior closed steam space 35, defined by a bottom wall 36 having a concave undersurface, bounded by downwardly extending marginal portions 31. Steam may be delivered to the space 35 at substantially constant, controlled pressure, from a suitable source by a pipe 38. Within the concavity below the wall 36, there is disposed a iiexible, distensible, impervious sack G, of rubber, rubber and fabric or any other A valve lil having an inlet42 communicating with the interior space 35 is arranged to deliver steam through branch pipes 43 to the interior of the sack 4D, the valve being controlled by a handle 44 or the like. A pipe 55, extending through the head and connected to a flexible rubber tube section 46 in communication with the interior of the sack it leads through a steam trap l5 for the removal of condensate.

The head I2 may carry steam and air valves 5t and 5 l. The steam valve, under the control of an operating handle 52, is adapted to deliver steam from the hollow space 35, through an intake conduit 53 and a discharge pipe 54 to the concavity below the head, exteriorly of the sack 48. Similarly, the air valve 5 I, under control of an operating handle 55 receives air from any suitable source through pipe 56 and delivers the same through a discharge pipe 51 to the space below the head, exteriorly of the sack 4U.

A pervious cover 6i) of exible material having a beaded edge 6l may be clamped around the lower margin 31 of the head, by means of a strap 62 and suitable clamps 63. The cover E!) is preferably fitted upon the lower surface of the head with a substantial amount of slack, to permit the sack d to apply high pressing pressure through the cover to a garment on the buck.

In the operation of this form of the invention,

a garment to be pressed is laid upon the buck` Y the handle 52 of valve r50 is manipulated to deliver steam from the space to the concavity in This steam,

the head, exteriorly of the sack dii. diffused throughout the entire yarea of vthe -lower surface of the head, flows through the pervious cover 60 into contact with and through the garment, to moisten and soften the garment.

liver steam from the hollow interior 35 of the head to the interior of the sack 49, whereupon the sack is inflated and pressing pressure is applied through the cover 6B, evenly to the garment, throughout the entire surface thereof. At the conclusion of the pressing operation, al1` may be delivered to the space above the head cover Bg, exteriorly of the sack, and a vacuum may be drawn through the buck by manipulating the vacuum valve 2l. garment removes moisture therefrom and sets the garment in the pressed condition. If desired, the air valve associated with the head may be eliminated and the suction line connected to the buck relied upon exclusively, to draw yatmospheric air through the garment to perform the drying function.

Instead of using steam as the iiuid pressure medium, compressed air may be delivered to the interior of the sack il from any suitable source, through a valve, controlled in any desired manner.

In the form of the invention shown in Figure 4, a plurality of independent sacks or cells 65 are employed, instead of a single sack, as in the rst form. The several sacks. are interconnected by a common header 66 in communication with a supply pipe 6T for the delivery to the cells of uid under pressure, either al1` or steam. Similarly, the space 68 between and surrounding the cells may be supplied with steam and air or either steam or air by Valve-controlled pipes 69 and lll.

Valve 4I may now be manipulated by handle 44, to de- This ow of yair through the i The concave space 58, below the several sacks may be closed by a perforated or pervious cover l2 of any suitable flexible material. The cover may be clamped in place by a marginal cord or cable 13 and a strap le.

The operation of this form of the invention is substantially the same as previously described.

In both cases, the garment is moistened by the delivery of steam to the head, in the space surroundingr the inflatable member or members and/or steam delivered to the space below the perforated top plate of the buck. After moistening, the sack or sacks are inflated by fluid under pressure (steam or air) and pressure is applied to the garment through the cover on the undersurface of the head. After :a suitable pressing time, the supply of uid under pressure is cut off. While the head is Still in its lowered position, the valve 5i may be opened to deliver drying air to the concavity in the head, eXteriorly of the sack or sacks. This air flows through the pervious cover of the head, through the garment, through the pervious cover on the buck, and into the chamber therebelow. The vacuum valve may be opened to facilitate this iiow of air. Even though the sack or sacks are deiiated at this time, so as not to apply pressing pressure to the garment, the pervious cover of the head will beheld firmly upon the garment, to maintain the latter smoothly on the buck, by the flow of air from the head through the cover.

After the head has been raised, the vacuum valve may again be opened, to connect the hollow interior ofthe buck to the source of vacuum, lthereby to draw atmospheric air through the garment, for final drying.

VIt must be understood that the showing in the accompanying drawings is largely diagrammatic and is made for purposes of illustration and not by way or" limitation. For instance, valves of Yany suitable type may be substituted for those shown, vand may be mounted whereve1` desired, and operated by any suitable means, known to vthe art. Moreover, other means for raising, lowering, and locking the head may be substitut^d.

The apparatus described above includes means associated with both the head and the buck for subjecting the garment to steam for moistening and to air for drying. It should be understood, however, that these iiuid delivery arrangements may be associated with either the buck vor the head, or one with each only. In other words, steam may be applied to the garment from either the head or buck, or from both as described above. Similarly, air may be delivered to the garment from the head or suction through the buck ma?)7 be relied upon exclusively.

'I-Ience, it should be understood that the invention is not limited to the details of construction shown 4in the drawings and described above, but includes all modifications coming within the scope of the appended claims and equivalent constructions.
