s 13 Claims. (Cl. 223-67) This invention relates to, garment finishers in the nature of that disclosed in my US. LettersPatent No. 2,736,471, and more particularly to improvements in the bag structure therein disclosed, the primary object being to eliminate wrinkles in garmentsthat are draped over the bag during the finishing process.

In by patent above-identified there is disclosed novel take-up means in the nature of drawstring structure that is attached to the bag therewithin at a number of locations throughout the length thereof for taking up the fullness of the bag and thereby varying the extent of ballooning of such bag when fluid pressure is directed thereinto. Such take-up means has proved successful and almost absolutely essential to adapt a single bag for receiving any one of a large class of garments of differing sizes and shapes. The operator can easily and quickly adjust the various drawstring structures so that when the bag is inflated, it will properly balloon tightly to the shape, size and configuration of the garment draped thereon.

However, it is manifest that drawstring means inherently draws the material from which the bag is made into a plurality of gatherings and such gathering or wrinkling of the bag is oftentimes transmitted fromthe bag into the garment itself, thereby wrinkling the latter during the finishing procedures, Such wrinkling of the garments which occurs more particularly when a rather drastic lessening of the bag diameter is needed for smaller garments, is found to occur especially at the frontand at the rear of the garment adjacent certain clamps that are employed as a part of the finisher in the manner disclosed in my patent aforementioned.

It is the most important object of the present invention, therefore, to provide a bag having improved take-up means, as well as certain other advantageous features operable in conjunction with the take-up means'and otherwise, to prevent wrinkling of the bag and, therefore, the garment to be finished at certain localized areas, especially along the said clamps, as well as adjacent the front of the garment near the neck thereof.

Another important object of the present invention is to provide improved drawstring structure that is connected to the bag in a novel manner through use of straps, rings, loops and the like, primarily for the purpose of eliminating wrinkles as aforementioned, and secondarily, to prevent tearing of the material from which the bag is made when the latter is taken up by the drawstrings.

A further important object of the instant invention is to provide an improved bag capable of accomplishing the needed results above outlined by virtue of the inclusion of means for maintaining the effective length of the bag at the front and back thereof substantially constant while the sides of the bag may be adjustably gathered'to change the effective length thereof whereby the fullness of the bag adjacent thereto may be controlled.

,A still further object of the present invention is to provide loop means such as a resilient element at the front and upper end of the bag and cooperable with the structural components above mentioned for accom modating low-neck garments, sport shirts and other clothing, and at the same time eliminate wrinkling thereof,

2,990,982; Patented July 4, 1961 2 regardless of the extent to which it may be necessary to reduce the diameter of the bag at the waist.

An additional important object of the instant invention is to provide an improved bag having means thereon to prevent upward creeping of the garment toward the waist zone of the bag, especially when the bag is drastically restricted at such waist zone through use of the take-up means therefor.

In the drawings: 1

FIG. 1 is a fragmentary, front elevational view of a garment finishing machine in the nature of that disclosed by my patent above set forth showing the improved bag structure of the instant invention operably mounted thereon;

FIG. 2 is a fragmentary, side elevational view of the finisher shown in FIG. 1, the bag .being partly broken away for clearness;

FIG. 3 is a substantially longitudinal, cross-sectional view through the bag on an enlarged scale, the bag being entirely removed from the finisher;

FIG. 4 is a schematic, perspective view of the drawstring loops of the take-up means at the waist of the bag;

FIG. 5 is a view similar to FIG. 4 showing the draw: string loops of the take-up means adjacent the lower open end of the bag; and

FIG. 6 is an enlarged, fragmentary, internal perspective'view at the lowermost open end of the bag showing one of the loop members and proximal component parts of the bag.

Aside from the bag itself, broadly designated by the numeral 10, garment finisher 12 shown for illustrative purposes only in FIGS. 1 and 2 of the drawings, forms no part of the instant invention and may be similar in nature to the finisher disclosed in my Patent No. 2,736,471 aforementioned. Accordingly, the disclosure of said patent is incorporated herein by reference as may be needed for a full understanding of the function and use of the improved bag 10 about to be described.

Bag 10 may be made from any flexible material that is sufficiently porous to be permeable to the flow of steam and/or air therethrough emanating from hollow base 14 forming a part of the finisher 12.

Hollow bag 10 is supported by the finisher 12 through the medium of an upstanding frame member 16 within the bag 10 and terminating in a neck element 18 attached to the frame member 16 at the upper end of the latter. Laterally extending arms 20 on the neck element 18 are received by openings 22 in the bag 10, and which openings 22 are in turn provided with slide fastener closure means 24. Opening 26 at the upper end of the bag 10 clears the neck element 18. The lowermost open end of the bag 10 is attached to the base 14 in any suitable manner such as through use of an annulus 2-8 which bag 10 surrounds.

The lowermost peripheral edge or margin of the bag 10 is hemmed to present a piping 30 receiving a drawstring 32 which, when tied in a knot 34 as shown in FIG. 2, clamps the lower open bottom of the bag 10 tightly to the annulus 28.

When the finisher is placed in use, the garment (not shown) draped over the bag 10, is held in place at the front and at the back thereof through use of opposed clamps 36 and 3-8 cooperating with rigid backing strips 37 within the bag 10 and carried by the frame member 16 by a suitable mount 39.-

In accordance with the improvements of the instant invention, take-up means broadly designated by the numeral 40, is provided for the bag 10 intermediate the ends thereof and particularly at the waist zone thereof, and take-up means 42 is provided for the bag 10 adjacent the bottom thereof but spaced upwardly from the piping 30 and drawstring 32.

Tak'e up means 40 includes a pair of

drawstring loops

44 and 46 within the bag and a piping 48 is provided for each

loop

44 and 46 respectively. Pipings 48 are attached to the bag 10 therewithin at opposite sides thereof in diametrically opposed relationship, and receive the bights of the

corresponding loops

44 and 46. The pipings 48 do not, however, extend across the front and the back of the bag 10; at such zones there is provided a pair of elongated straps 50 and 52 of relatively heavy material such as buckram, canvas or the like, attached rigidly to the inner face of bag 10 as by stitching.

An eye element such as a metallic ring 54, is attached to each end of each strap 50 and 52 respectively, and it is through these four rings 54 that the

loops

44 and 46 are threaded. In that respect it is clearly seen in FIG. 3 that the drawstring loop 44 passes from the ends of the piping 48 therefor, and thence through a ring 54 on strap 50 and a ring 54 on strap 52. Loop 46 is arranged in the same manner on the opposite side of the bag 10 and suitable fasteners 56 connect the ends of each

loop

44 and 46.

A flexible chain, cable or the like 58, joins with fasteners 56 with mount 39 for backing strips 37 as seen in FIG. 2. Chain 58 is trained around a pulley 60, in turn connected with a flexible cable 62, the latter of which is actuated by a pull knob 64 in a manner more particularly described in my said patent.

At the lower end of the bag 10 adjacent the front and rear thereof, there is provided a pair of

members

66 and 68 fastened at their uppermost ends adjacent the takeup means 42 and looped beneath and around the piping 30 and drawstring 32 in the manner best illustrated in FIGS. 3 and 6.

The

members

66 and 68 are made from relatively strong material that is substantially heavier than the material of the bag 10 and

such members

66 and 68 gather together the lowermost margin of the bag 10 between take-up means 42 and piping 30, as indicated by the numeral 70. This reduces the effective length of the bag 10 at the front and at the rear thereof, leaving the sides of the bag relatively full, it being seen in FIG. 3 that side margins 72 of the bag 10 beneath the take-up means 42 progressively decreases in width in both directions as the

loop members

66 and 68 are approached.

Each

member

66 and 68 is provided with an elongated strap 74 within the bag 10, not unlike the straps 50 and 52 and, in the same manner as in the drawstring structure 40, each strap 74 has a ring 76 secured to each'end respectively thereof.

Additionally, there is provided a small, upstanding strap 78 of heavy material at each side respectively of the bag 10 therewithin, and each of the two straps 78 is in turn provided with a ring 80.

Four

drawstring loops

82, 84, 86 and 88 are provided for the take-up means '42, it being noted in FIG. 3 that loop 82 passes through one ring 76 adjacent member 66 and through one ring 80, as well as through a piping 90 extending between the last-mentioned

rings

76 and 80. Similarly, the loop 84 has its bight threaded through a 'piping 92 stitched to the inner face of bag 10, and this loop 84 passes through the same ring 80 and through one of the rings 76 adjacent the rear loop member 68.

Loops '82 and 86 are threadedthrough an eye 91 on crossbar 93 of annulus 28 and

loops

84 and 88 pass through eye 95 on bar 93. The two

loops

86 and 88 are similarly arranged at the opposite side of the bag 10. All of the

loops

82, 84, 86 and 88 are provided with fasteners 94 not unlike the fasteners 56, which are coupled with a common chain or the like 96, as shown in FIG. 5, which passes over a pulley 98 and attaches to mount 39. A flexible cable 100 interconnects the chain 96 and another actuating knob 102 through a pulley 103.

The front loop member 66 is in alignment with the front strap 50 as shown in FIG. 1, and with a loop element 104 which may be made from elastic material if desired, and which element 104 is looped over the neck element 18. The loop element 104 is attached at its ends directly to the front of the bag 10 immediately below the opening 26 therein.

It is to be seen especially when viewing FIGS. 1 and 2, that when the bag 10 is taken up at the waist zone thereof by the drawstring structure 40 to reduce the effective diameter thereof, garments draped over the bag 10, especially relatively short garments such as shirts, blouses, jackets and the like, tend to creep upwardly toward the reduced waist zone of the bag 10 when the latter is inflated. Accordingly, there is provided a plurality of frictional strips 106 on the outer face of the bag 10 between the lower end thereof and the take-up means 40. Strips 106 may be made from any suitable material and have their outer faces roughened as by use of a selected vinyl product carrying an abrasive sprinkled along the strips 106 and made from Carborundurn dust or other roughening substance.

In use, the bag 10 is adjusted through use of the pull knobs 64 and 102 to the size and shape of the garment to be finished thereon. When the knob 64 is pulled outwardly to exert a pull on the

drawstring loops

44 and 46, the material forming the bag 10 is gathered together only along the two pipings 48 and such material remains relatively flat and unwrinkled or ungathered along each of the two straps 50 and 52.

Similarly, when the knob 102 is actuated to take up the

loops

82, 84, 86 and 88, the gathering takes place entirely at the two sides of the bag 10 along the pipings and 92, as well as the corresponding pipings for the

loops

86 and 88. This leaves the bag 10 ungathered and relatively flat at the front and back thereof adjacent the

elements

66 and 68.

Still further, the loop element 104 holds that zone 108 of bag 10 relatively flat, zone 108 extending between the take-up means 40 and the loop element 104. Thus, the loop element 104, the front strap 50 and the front member 66, cooperate in preventing wrinkling of the bag throughout the entire front thereof, and when the clamp 36 is brought against the garment to press the latter against the proximal backing strip 38, such garment will not be wrinkled during the processing of the garment through use of steam and air in the manner outlined by my patent aforementioned.

The use of the rings 54 causes the straps 50 and 52 to be held taut when a pull is exerted upon the

loops

44 and 46 and in a similar manner, the rings 76 hold the straps 74 in a longitudinally taut condition when the

loops

82, 84, 86 and 88 are pulled simultaneously through use of manual control 102.

The use of the four

loops

82, 84, 86 and 88, together with the added advantage of the chain, pulley and cable arrangement shown in FIG. 5, multiplies the effect of pulling on knob 102 so that there may be a wide variance in the maximum and minimum diameters of the bag 10 at its lowermost zone. Also, as knob 102 is pulled to reduce the diameter of bag 10, the latter is pulled downwardly because of the difference in elevation between eyes 91 and and the

pipings

90 and 92.

Such increase in the amount of reduction in the effective diameter of the bag in relation to the extent of pulling of the knob 102, permits, for example, a diameter range of from 24 to 90 inches, whereas heretofore, in structures not incorporating the advantages of the present invention, the maximum range was approximately from 36 to 64 inches.

Another advantage worthy of emphasis lies in the oval configuration of the bag that is attained by the structure above described. The minor axis of such transverse elliptical shape of the bag 10, extends between clamps 36 and 38 thereby allowing more room for operation between such clamps and the bag 10 during draping of the jgarment onto the bag and removal of such garment thererom.

Still further, since the major axis of the bag extends in the opposite direction, the bag moreaccurately conforms to the shape and configuration of most garments to be treated through the apparatus forming the subject matter of the instant disclosure.

Having thus described the invention what is claimed as new and desired to be secured by Letters Patent is:
