APPARATUS FOR FINISHING DRY CLEANING Filed Oct. 12, 1964 LLOYD W. Kl LLEY INVENTOR.

ATTORNEY.

United States Patent 3,262,615 APPARATUS FOR FINISHING DRY CLEANING Lloyd W. Killey, 421 N. Main St., Monmouth, Ill. Filed Oct. 12, 1964, Sei'. No. 403,186 3 Claims. (Cl. 22367) The present invention relates generally to garment finishing machines, and more particularly to improved methods and apparatus for finishing garments.

The principal object of the present invention is to provide a method of and apparatus for finishing' garments in which a garment to be finished is placed over an inflatable bag and steam is introduced into the bag, the bag being provided with suitable apertures whereby the steam introduced into the bag may escape in sufficient quantities and with suflicient force to inflate the garment held over the form to its natural shape, thereby finishing the garment.

In prior ant devices of the type illustrated in the US. patent to Petit 2,412,172, issued December 3, 1946, and the more recent US. patent to Jackson 2,990,983, issued July 4, 1961, it has been the practice to place a garment over an inflatable bag of relatively non-porous material, such as a closely Woven nylon, and to fully distend and inflate the bag as far as possible to cause the garment placed over the bag to become fully distended and placed in intimate contact with the bag.

The prior art devices have not been satisfactory since it has been necessary to provide drawstrings and other devices to suitably control the size to which a bag will balloon when inflated. Thus, if the size were not controllable it would not be possible to use a single bag for all sizes of garments since if the inflatable bag were made of a size large enough to fully distend the largest garment likely to be encountered, it would not be possible to properly finish a smaller garment since the bag would, when inflated, tend to stretch the garment. Conversely, if a small bag were employed, it would obviously not fully distend the larger size garments. While the use of drawstrings has permitted the use of a universal bag, it has had its disadvantages in that the drawstrings cause the material of the bag to form into a plurality of gatherings and such gatherings sometimes cause the garment upon the inflated bag to become wrinkled in a complementarymanner.

Another principal disadvantage of the prior art devices is that it is necessary to adjust the various drawstrings for each different size garment to be finished upon the bag, and unless the drawstrings are properly adjusted the garment will'not be properly finished, and these adjustments take time which could otherwise be used for the actual finishing of the garment.

Still another disadvantage of the prior art devices is that the material of the bag has been made of a relatively closely woven nylon to retain suflicient quantities of the steam and air within the bag to hold it in a fully inflated semi-rigid condition, it being the theory of operation of the prior art devices that the garment placed upon the bag must be in intimate contact with the bag, and to be, in effect, pressed by the bag. However, the material of the bag has not been sufliciently porous to permit enough steam and entrained moisture to pass through the bag in a reasonable time to finish the garment placed upon the bag and thus it has been necessary for the operator of the finishing machine to use a hand spray gun to place suflicient moisture upon the garment to finish it. 1

Therefore it is an object of the present invention to provide a new method of and apparatus for finishing dry cleaning which will overcome the disadvantages of the prior art finishing devices.

3,262,615 Patented July 26, 1966 More particularly, it is an object of the present invention to provide an improved inflatable finishing bag having relatively porous and relatively non-porous portions so arranged and constructed that steam under pressure entering into the bag will distend the bag and will escape through the relatively porous portions in sufiicient quantities to fully distend a garment held over the form, the garment being distended to its natural shape and being finished by the escaping steam and entrained moisture.

Another object of the present invention is to provide a garment finishing bag which will, when used in conjunction with a conventional garment finishing machine, cause the garment placed over the bag to become fully distended and finished without the application of moisture from the exterior of the garment.

A further object of the present invention is to provide an inflatable garment finishing bag which can be used for all sizes of garment without adjustment.

A still further object of the present invention is to provide an improved method of finishing garments in which the garment to be finished is caused to be inflated to its natural shape by steam, the steam finishing the garment.

Another object of the present invention is to provide an improved apparatus for finishing the collars of garments placed over the shoulder and neck portion of that frame which normally supports .an inflatable garment finishing bag. More particularly, it is an object of the present invention to provide an improved collar finishing device usable in conjunction with an improved inflatable bag that permits the escape of suflicient quantities of steam and entrained moisture to finish the garment without a pressing action from the bag and without the application of moisture to the exterior of the garment being finished, the improved collar form holding the collar of the garment away from the neck portion of the frame which supports'the improved finishing bag, thereby permitting the egress of sufficient quantities to finish the collar portion. It should be noted that in the prior art finishing machines it has not been possible to finish collars without a separate touch-up finishing operation.

These and other objects and advantages of the present invention will be apparent to one skilled in the art, after a consideration of the following detailed description taken in conjunction with the accompanying drawings in which a preferred embodiment of the invention is illustrated.

FIG. 1 is a front perspective view of the garment finishing bag built in accordance with the principles of the present invention, the bag being shown mounted on a frame of a generally conventional garment finishing machine.

FIG. 2 is a fragmentary rear view of the bag and improved collar form of the present invention.

FIG. 3 is a side view of the bag and collar form shown in FIG. 2.

FIG. 4 is an enlarged perspective view of the collar form shown in FIGS. 2 and3.

According to the principles of the present invention, an improved bag, indicated generally at 10, is disposed over a frame having front and rear backing members, 12 and 14, respectively, and a shoulder and neck support 16 mounted on the upper ends of the backing members, the support 16 being adjustable in width, as is conventional. The supports 12 and 14 are mounted upon an annular base 18 which is in turn secured to a conventional garment finishing machine of the type disclosed in US. Patent No. 2,736,472, issued February 28, 1956, to Nolan C. Jackson, and partially illustrated at 20.

The bag 19 has a lower skirt portion 22, a narrow waist portion, indicated generally at 24, and a chest and shoulder portion illustrated generally at 25. Each of waist and skirt portions is sized to be less when inflated than that of the smallest garment to be finished upon the machine. The shoulder portion, however, is made large enough to support the largest garment to be placed upon the finishing machine, but the chest portion narrows down to the waist portion for reasons to be fully set forth below.

The skirt portion of the bag is made entirely of a flexible relatively non-porous material, such as a closely woven nylon fabric customarily found in prior art garment finishing bags.

The waist portion of the bag is formed as a continuation of the skirt portion and is provided with a plurality of areas that permit the relatively free passage of steam and entrained moisture. Thus the waist 24 is provided With a lower generally cylindrical band of webbing or other relatively open fabric 26, an intermediate cylindrical band of webbing 28, and an upper generally cylindrical bad of webbing 30.

The lower band is secured at its lower edge to relatively non-porous front and back fabric portions, 32 and 33, respectively, these portions being formed as a continuation of the skirt portion 22. The upper edge of the band 26 is secured to a first intermediate strip of flexible relatively non-porous material 34. A second intermediate strip is disposed between the intermediate and upper bands, 28 and 30, resp'etcively.

The upper band 30 encircles the entire waist portion as can be seen from FIGS. 1 and 2 while the intermediate and lower bands 28 and 26, respectively, do not entirely encircle the waist, being interrupted in the back by an extension portion 38 of the back portion 33. The portion 38 extends upwardly to the second band 36 and covers a portion of the rear backing member 14.

Interconnecting the front and rear relatively nonporous fabrics portions, 32 and 33, respectively, are rightand lefthand relatively porous .bands, 40 and 42, respectively.

The front of the shoulder and chest portion 25 of the bagll) is formed entirely of the same relatively nonporous material found in the skirt portion 22. However, the back of the portion 25 is provided with a wide band of porous material 44 across the shoulders, the band being of substantially the same material as the bands 26, 28, 30, 40, and 42. Above the band 44 is another relatively porous band 46 which is located near the neck, there being rightand left-hand web portions 48 which extend slightly forwardly of the band 46. Thus, a relatively non-porous section 51 disposed in circumscribing relationship to the neck opening 53 is provided proximal the upper end of bag 10.

Cooperating with the front and rear backing members, 12 and 14, respectively, are front and rear clamps, 52 and 50, respectively. The rear clamp is generally conventional and may be of the type illustrated in the aforementioned Petit Patent No. 2,412,172. The front clamp is also of conventional construction, and it is preferably mounted in the manner illustrated in my copending patent application Serial No. 341,048, filed January 29, 1964. To this end the clamp is mounted on a swingable support including an upwardly extending bracket 54 which is fixed to a swingable arm 56 that is pivoted at 58 to a pair of apertured lugs 60 carried by the base 18. The clamp includes a garment engaging pad 62 which is disposed in a generally vertical position and is adjustably adapted to be forced against a garment placed upon the bag 10, the pad bearing through the garment against the front backing member 12 for holding the garment in position. The pad is pivoted to a spring arm 64 that at its lower end is removably fixed to a channel arm 66 pivoted at 63 to the rigid arm 54 of the swingable support. The upper end of the channel arm 66 pivotally receives a short link 70, the other end of which is pivoted to a lever 72, the lower end of which is pivoted at 74 to the bracket 54.

4 In order to lock the arm 56 to the base 18 a detent bar is provided, the bar being rigidly fixed at its upper end to the channel arm 66 in any suitable way. The lower end 78 of the detent bar can be secured behind the detent in the manner more fully set forth in my aforementioned copending application. The clamp pad 62 is held in engagement by placing the pivot between the link 70 and the lever 72 in an over-center position relative to the pivot 74 and the pivot between 70 and the channel arm 66.

Opposed zippers 82 are provided on either side of the shoulder portion of the bag.

A collar form is mounted on the finishing bag frame over the bag 10. The collar form includes a curved resiliently flexible collar engaging strip 84 formed preferably of spring stainless steel and mounted on an arm 86 that is pivotally secured to a mounting plate 88 which is in turn secured to the rear backing member 14 by means of screws 90 or other conventional fastener means. The collar form is normally biased outwardly by means of a spring $2 which may be secured to arm 86 and plate 88 respectively.

When the collar form is not to be used, as when finishing sweaters and the like, it is held against the neck portion 94 of the adjustable shoulder support 16 by means of a wing nut 96 on a stud bolt 98 mounted for sliding movement within the slot 100 on the neck portion. To hold the collar form down it is only necessary to dispose the bolt in the slot 102 on the collar form and to hold the form down with the nut 96.

In operation the garment to be finished is placed over the bag 10, which is supported on frame 12, 14, 16. If the garment is a mans suit coat, the back vent is held closed by means of the back clamp 50 which is brought to bear against the backing member 14. The front of the coat is also closed by means of the front pad 62 which is brought to bear against the front backing member, the front flaps of the coat being held together between the pad and the backing member. The adjustable shoulder support is then adjusted to extend the entire width of the coat, and the collar form is released from the wing nut 96 and bears against the collar of the coat by means of the spring 92. The collar of the coat is thus held slightly away from the bag 10 and the shoulder and neck portion 16. Steam is then introduced into the bag. The steam is preferably saturated at 40 to 100 pounds boiler pressure and is introduced into the bag at the rate of about 1000 cubic feet per minute. It should be noted that the foregoing figures are not intended as a limitation and that different rates, temperatures, and saturations will be apparent to those skilled in the art. As will also be apparent to those skilled in the art, as the steam is introduced into the bag, it will expand and reduce in temperature. Thus a portion of the saturated steam will condense. The steam entering the bag will initially cause the bag to balloon into the shape illustrated in the drawings. As further steam is introduced into the bag 10, steam and entrained moisture will escape through the relatively porous portions of the bag. It is a feature of this invention that the steam and entrained moisture will escape in suflicient quantities to distend the garment placed over the form to its natural shape. The shoulder, Waist, and skirt portions of the bag help to confine the steam and entrained moisture between the bag and the garment thus assuring that sufficient pressure is exerted upon the garment to extend it outwardly to its natural shape. The steam that escapes through the porous shoulder and neck portions will distend the back of the coat in the vicinity of the porous strips, the steam flowing upwardly under the collar form and also downwardly towards the waist portion 24 of the bag finishing the back of the coat between the Waist and the neck. It should be also noted that some of the steam which escapes through the portion 46, 48 is forced over the shoulders and down between the front of the garment and the front of the bag, and other steam is forced around the side.

The steam being discharged through the portions 26, 28 and 3t) will help fill out the lower portions between the waist and the shoulders and will alsocause the lower portion of the coat to become distended to its natural size. The portions 40, 42 help stabilize a suitcoat as it is being finished by keeping it from fluttering.

Other garments are finished in substantially the same manner set forth above. It should be noted however that because of the relatively narrow waist of the bag that it is necessary to supply more steam in the area to assure that a garment such as a mans coat will become fully distended. It should also be noted that the woven nylon which forms the relatively non-porous portions of the bag strains that moisture which condenses from the steam in the bag, permitting only a small portion of dry steam to pass through the relatively non-porous portions of the bag.

By opening the zipper 82, it is possible to introduce steam into the sleeves of a garment. Thus, when finishing a coat, the zippers 82 are opened and the sleeves of the coat are finished by the steam and entrained moisture escaping through the zippers 82, the sleeves being held open upon sticks as is conventional.

In the foregoing description, the terms porous and nonporous mean that when the two materials are combined in a finishing bag that substantially all the steam will escape through the more open porous material while causing the porous and non-porous materials to become distended. The relatively non-porous material may, however, be porous in the absolute sense, as for example permitting the escape of relatively small quantities of dry steam if no porous material was present.

While the preferred structure in which the principles of the present invention have been incorporated is shown and described above, it is to be understood that the invention is not to be limited to the particular details, shown and described above, but that, in fact, widely different means may be employed in the practice of the broader aspects of my invention.
