Referring more in detail to the drawings: The reference numeral 1 generally designates a garment ing and drying the upper portions of various sized trousers and the like. The garment treating apparatusl is supported on a tubular upright portion or hollow stand 2 which is secured to a base 3 and the stand 2 extends upwardly therefromand has a which extends forwardly from the stand 2. An expansible garment treating or pressing form 5 dependsfrom the upper support portion 4 and is adapted to expand and contract to conform to a garment 6, such as trousers, slacks and the like. A pair of self adjusting pleat pressing clamps 7 and 8 are operable in conjunction with the expansible form 5.

In the illustrated structure, the upper support portion 4 is a hollow horizontal extension ofthe stand 2 and is provided with a steam discharge manifold 9 which is carried by, and which is positioned adjacent a forward end of the upper support portion 4. The steam discharge manifold 9 extends downwardly into the center of the expansible form 5, as best seen in FIG. 5.

Heated air supply means are provided for inflating a permeable air bag assembly 10 which is mounted on and encloses the expansible form 5. The air supply means comprises a motor driven blower 11 which is carried on a rear portion of the base 3, and the air discharge opening of the blower ll communicates with a corresponding opening provided adjacent the bottom of the hollow stand 2. Air entering the upright stand 2 is directed upwards into the stand 2 by means of a diverter plate 12 which is carried therein and which may be seen in FIG. 2. Air passing upwards through the tubular stand 2 is heated by means of a suitable steam radiator 13 which is mounted in a lower portion of the stand 2 and the radiator 13 comprises a series of serpentine steam heating tubes 14 which are provided with fins 15 to increase the heat radiating capacity thereof, as best seen in FIGS. 2 and 3.

The upper support portion 4 of the apparatus 1 has a horizontal air duct structure 16 therein and the air duct structure 16 is in pneumatic communication with the upper portion of the stand 2. The air duct structure 16 extends forwardly from the tubular stand 2 to a position directly over the expansible form 5, as best seen in FIG. 2. The air duct structure 16 has a separate forward compartment 17 therein positioned above the expansible form 5. The compartment 17 is formed by an air damper 18 which extends across the air duct structure 16 for the purpose of selectively admitting heated air to the forward compartment 17 or pneumatically sealing off the compartment 17 from the air duct structure 16.

The air damper 18 is operable by means of a suitable electric cylinder or solenoid 19 which is carried by a sidewall of the air duct structure 16 and which is best seen in FIG. 4. The forward compartment 17 of the air duct structure 16 is provided with a series of apertures 20 in one wall thereof, preferably the bottom thereof, for discharging heated air therethrough into the expansible form 5 and air bag assembly 10 by means of an adapter or transition 21 which is secured to the underside of the upper support portion 4 and the transition 21 has an air discharge nozzle or duct 22 for communicating with an air inlet opening in the top of the inflatable air bag assembly 10. The transition 21 acts also as a venturi to increase the velocity of the air entering the air bag assembly 10, as best seen in FIGS. 3 and 5.

The steam discharge manifold 9 has a pair of inner steam chambers 23 and 24, a centrally positioned, open tubular bore or cavity 25 extending completely through the manifold. and an outer steam discharge chamber 26 which is formed by a tubular jacket 27 having a plurality of orifices 28 therein for the discharge of steam therethroughyas best seen in FIGS. 5 and 9. The steam chambers 23 and 24 are divided by means of diametrically opposed baffle plates 29 and 30 which extend downwardly between the chambers 23 and 24 to a point near the bottom thereof in order that condensate will not be allowed to remain in the chambers 23 and 24 but will be discharged from the manifold 9. The tubular cavity 25 provides a central access through the manifold 9 for a driving rod or plunger of the form expansion mechanism, which plunger passes independently and completely through the manifold 9, as will be later described.

Steam enters the garment treating apparatus 1 from a suitable source of supply (not shown) which is connected to a steam conduit 31 which enters at the rear of the apparatus and extends upwardly within the stand 2 and is connected to an angular steam conduit 32 which terminates in a steam inletjunction block 33. A steam conduit 34 is connected to the block 33 and communicates with a steam inlet opening 35 of the steam discharge manifold 9, as best seen in FIGS. 2, 3 and 9.

Steam entering the manifold 9 will be admitted through the inlet opening 35 and discharged into the chamber 23 and will be conducted downwardly therein passing below the baffle plate 29 and 30 and will rise on the opposite side of the baffle plates in the chamber 24. Condensate entering the manifold 9 with the steam (or condensate forming therein) will be forced upwardly within the chamber 24 and will be discharged with the steam flow through an outlet opening 36 of the manifold 9 into a steam conduit 37 which communicates with a steam junction block 38 as best seen in FIGS. 2 and 3.

An arcuate steam heating conduit 39 is connected at one end to the steam inlctjunction block 33 and is connected at its opposite end to the steamjunction block 38. The conduit 39 is soldered, or otherwise suitably secured. to the underside of the upper support portion 4 and to the transition 21 for the purpose of maintaining these members in heated condition in order that free moisture in the form of condensate will not form thereon during use of the apparatus, as best seen in FIGS. 3 and 5.

An angular conduit 40 (which is similar to the angular steam conduit 32) has one end connected to the steam junction block 38 and the other end connected to a steam conduit 41 which extends downwardly into the stand 2 and communicates with a sidewall of a suitable steam separator 42.

The steam separator 42 is enclosed within an enlarged cylin' drical tank which is carried within the stand 2 by means of brackets 43. A steam conduit 44 has one end connected to the bottom of the separator 42 and the other end connected to an inlet manifold 45 of the steam radiator 13. A suitable conduit. such as a pipe nipple 46, is connected to an outlet manifold 47 of the radiator 13 and extends laterally out the rear of the stand 2 and communicates with a conventional steam trap (not shown) for the purpose of discharging spent steam and condensate from the garment treating apparatus 1.

An inlet side of a magnetic steam valve 48 communicates with the top center of the steam separator 42 for obtaining dry steam therefrom and a steam conduit 49 has one end connected to a discharge side of the steam valve 48 and the other, end connected to a steam conduit 50 which passes between the angular conduits 32 and 40, as best seen in FIGS. 2 and 3. The steam conduit 50 communicates with the steam discharge chamber 26 of the steam manifold 9 by means ofa steam conduit 51 and an inlet opening 52 connected to the tubular jacket 27 ofthe manifold 9.

The steam conduits 32 and 40 are secured to the conduit 50 as by being soldered or otherwise suitably secured thereto and to the upper support portion 4 for maintaining these members in heated condition to avoid the formation of condensate during use of the garment treating apparatus 1.

When the magnetic steam valve 48 is actuated, dry steam will flow from the separator 42 into the

conduits

49,50 and 51 and will be discharged through the orifices 28 in the jacket 27 of the steam manifold 9 into and through the expansible form 5 and air bag assembly 10 and thence through the fibers of the garment under treatment, thereby resulting in a reduction of pressure within the separator 42. Simultaneously, new steam from the source of supply (not shown) will be caused to flow through the

steam conduits

31, 32, 34 and 39', the steam chambers 23 and 24; and the

conduits

37, 40 and 41, thereby maintaining the upper support portion 4, the conduit 50, the manifold 9, and the transition 21 in heated conduction during use of the garment treating apparatus, as best seen in FIGS. 2, 3, 5 and 9.

A suitable vacuum valve 53 is mounted on the top of the air duct structure 16 and is in communication with the forward compartment 17 thereof by means of a nipple extension 54. The vacuum valve 53 is operable by means of a solenoid 55 which is positioned adjacent the vacuum valve 53 and is carried on the top of the air duct structure 16, as best seen in FIGS. 2,4 and 5. An outlet side of the vacuum valve 53 communicates with an angular vacuum conduit or tube 56 which ext'ends out through the rear of the stand 'Zand communicates with a central vacuum system (not shown When the-vacuum valve 53 iszactuated. a vacuum willbe formed within the forward compartment 17 and within the expansible form 5 and associated air bag assembly 10. The air damper'l8 will be closedby means of asuitable compression spring (not shown) within the damper cylinder or solenoid'l9at all times except when the air blower ll is-inuse. The vacuum meansa'nd the air supply means are not employed simultaneously during use of the garment treating apparatus. therefore. the vacuum valve 53 and the air-damper 18 will not in conflict one with theother; i 3 i i i 5 The expansibleform 5 has a series of contoured 'padded sections, designated'by'the' letters A.

The pad 76 is illustrated as having inner and outer layers of highly porous padding material' 78 and-79 respectively between whichiis stitched, or otherwise suitably secured. a layer; of fine metal mesh or screen 80. Each of the layers ofporous

78 and 79 has a permeable textile fabric pad cover'al form sections. The pairs of. parallel arms 57 and 58'are ;ar-

ranged in a cluster about the steam manifold 9 and'are. positioned completely; below the upper support portion 4 and within the transition 3! and air bag assembly 10. I An air cylinder 6! is-centrally disposed above the'compartment 17 of the duct' l6'andw'ithin 'a forward part of the upper support portion v4-andis carried on a-bracket 62 which is secured to the upper support'portion. (The aircylinder 61 has an elongatedjrod or plunger63 which'extends downwardly through the compartment 17 and the bore orcavity 25 of the 'steam' discharge manifold gz' The plunger "63' extends completely through the manifold 9 and its lower end is guided in reciprocable move'mentwithin a-bushing 64 which is fixed on the lower end of the manifold 9. A circular plate 65 is.

' thereto when the air cylinder 61 is void of compressed air. The spring 68 is seated at its lower end on the top of the steam manifold 9. and is seated at its upper endon a fixed disc 69 carried on the plunger 63.

The plunger 63 passes through a suitable electrically operated collet type brake 70 which is carried on the underside of the fixed bracket-62 for engaging the plunger 63 when the brake 70 is energized, thus providing a means for locking the expansible form 5 in selective positions. as best seen in FIG. 5. and as will be later described.

A suitable fluid under, pressure, such as compressed air, enters the apparatus 1 from a suitable source of supply (not illustrated) through an angular air conduit or tube 71 which enters at the rear of the stand 2 and communicates with a suitable which secures the

respective padding material

78 and 79 on the frame 73 bymeans'of-a dr'awstring 82.. thus a smooth. resilient.-permeable, contoured outersurface is-provided for each ofthe expansible form sections A to H inclusive; 7

. If desired. the screen 80 may be mounteddirectly on the frame 73. The purpose of sandwichin y the screen. 80

' between-the two

padding layers

78 and 79 .is to prevent free moisture. in the form of condensate. which may gather on the screen 80 during the steaming operation. from flying loosely aroundwithin the'air bag-assembly 10- during the air drying operation. Thus any moisture which may gather on the screen 80. 'will be 'retained by the pad layers-78jand 79 and will be quic'klydis sipated or evaporated by theheated'air passing through the pad 76 during the drying operation.

- The expansible form sections C and G are formed or arched corresponding withthe proper shapeof a pair of trousers at the sides or outseamsthereof; Section A is formed to fitthe center front orflysection of the trousers and is bifurcated near itslower end, forming an elongated slot 83 for receiving a crotch portion of the garment 6 therein and section B is formed or arched to fit the center rear of thetrouser top. Sections B and H are shaped to fit the front portions of the trouser top where pleats may appear, and sections D and F are formed or arched to properly fit the bias rear portions of the trouser top above the hip pockets. These sections engage and support these critical portions of the trouser top. These critical sections of the trouser top will all be further apart. one from the other. as the trouser size increases. and'when the expansible form 5 is expanded or contracted insize. the path of travel of the expansible form sections A to H inclusive will be such that each form section will automatically be in the proper position and will fit its respective critical section-of the trouser top. whether the expaitsible form is in a retracted state for small trousers, as shown in FIGS. 2 and 7. or in a fully expanded state for large trousers, as shown in .I-IGSVS and 8. or in any expanded state therebetween for intermediate sized trousers.

' between the expansible form sections. to be treated and finished by the inflatable air bag assembly 10, as will later be described. i g i The inflatable air bag assembly 10 is similar in shape to the upper portions of a pair of trousers. andas large in size as the largest size of trousers to be treated on the apparatus. The air bag assembly 10 is a closed member having the pads 76 and the pad covers 77 sewn to the inside surface thereof, and the air bag assembly is mounted in covering relationship on the expansible form sections A to H inclusive, and is secured thereto as previously described. The air bag assembly 10 has a crotch portion 84 which extends from the top of the crotch slot 83 of section A to the lower end of the center rear section E, as best seen in FIG. 5. The air bag assembly has a closed top portion 85 and

leg end portions

86 and 87 which are closed at their lower ends, as best seen in FIGS. 1,5 and 8.

Exclusive of the top portion 85 and lower ends of the leg ortions 86 and 87 of the air bag assembly 10, the air bag 10 is preferably made of a suitable textile fabric which is woven with sufficient tightness to maintain a desired static air pres- 1 sure therein, yet having sufficient porosity to permit the free suitable means, such as by a drawstring 88, as best seen in FIG.

Since the air bag assembly 10 is a closed member, it will retain sufficient heat as radiated by the steam discharge manifold 9 and the heated transition 21 to maintain the members of the expansible form 5 in heated condition when the garment treating apparatus 1 is not in use. When the garment treating apparatus 1 is in use, the heated air discharged into the air bag assembly 10 will keep the expansible form members dry and in a heated condition regardless of the intermittent discharge of steam therein, as will be later described.

Unsupported portions 89 of the air bag assembly 10, between the form sections A to H inclusive, of the expansible form 5, will be rounded out to fit the noncritical areas of the garment 6 when the expansible form 5 is expanded and the air bag assembly 10 is inflated with heated air during the pressing operation, and any excess of the unsupported portions or sections 89 of the air bag assembly 10 will simply be gathered in folds between the sections of the expansible form 5, depending on the size of the trousers under treatment, and will not transfer impressions of the bag or the folds therein upon the face cloth of the garment.

The lower seat portion of the air bag assembly 10 is left free to fill a lower seat portion of the trouser top when the air bag assembly 10 is inflated in order that there will be no pocket impressions on the outer cloth of the trousers, and also in order that the air bag assembly 10 will automatically compensate for any variation in the size or shape of the crotch or lower seat portions of the trousers which may be due to alterations having been made in the garment.

When the expansible form 5 is to be retracted from the expanded state, the vacuum valve 53 will first be actuated, thereby introducing a vacuum within the air bag assembly 10, with the vacuum drawing the unsupported portions 89 of the air bag assembly 10 into neat folds between the sections of the expansible form 5, and simultaneously drawing the top portion 85, lower seat portion 90, the crotch portion 84, and the

leg end portions

86 and 87 of the air bag assembly 10 into folds or puckers within the expansible form 5 as it is brought into a retracted state. The excess of the air bag assembly 10 is thereby out of the way when the expansible form 5 is retracted for loading a garrnentthereon, as will later be described.

The pleat pressing clamps 7 and 8 are mounted on a pair of fixed

brackets

91 and 92 respectively which are positioned within the forward end of the upper support portion 4 and are disposed on directly opposite sides thereof substantially in line with the pleat pressing sections B and H of the expansible form 5. Each

ofthe brackets

91 and 92 has a pair of offset

bosses

93 and 94 for supporting horizontally disposed shafts 9S and 96 respectively. One end of each of a pair of elongate

angular arms

97 and 98 are pivotally mounted on the shafts and 96 respectively. An angular bracket 99 is pivotally mounted on the other or free ends of

thearms

97 and 98 and the bracket 99 has a press shoe or plate 100 mounted thereon.

The press plates 100 may be provided with a suitable coating, such as Teflon, to avoid the objectionable gloss or shine which may be imparted to some fabrics by the contact of bare metal surfaces, and each press plate 100 has asuitable electric strip heater 101 which is mounted on the exterior or backside of each of the press plates 100 forimaintaining the press plates in heated condition to avoid the formation of condensate thereon and to insure firm dry creases in the pleats ofthe garment. The strip heaters 101 each have automatic heat regulating controls 7 and 8' for maintaining a controlled temperature of the respective press plates 100 on the pressing clamps 7 and 8 respectively.

A pair of air cylinders 102 and 103 are secured to the tops of the fixed

brackets

91 and 92 respectively for operating the pleat clamp assemblies 7 and 8 respectively, as best seen in FIGS. 4 and 6.

Each shaft 95 is journaled in its respective boss 93 and each shaft 96 extends into its

respective bracket housing

91 and 92. Each shaft 96 has a spur gear 104 mounted thereon to mesh with a toothed rack 105 which is an extension of a plunger of the respective air cylinders 102 and 103, and each rack 105 is maintained in mesh and alignment with its respective spur gear 104 by means of a needle roller bearing 106, as best seen in FIG. 6.

Each angular arm 97 is complementary to, and is in parallel conjunction with, the respective angular arm 98 and serves the purpose of keeping the press plate 100 coordinated and in proper alignment with the respective pleat pressing section of the expansible form 5, as best seen in FIG. 6, and as will later be described.

A pair of double solenoid air valves 107 and 108 are mounted on the air inlet openings of the air cylinders 102 and 103 respectively, for controlling the operation of the pleat clamps 7 and 8 respectively, and the valves I07 and 108 are each provided with a pair of solenoids 109 and 110, and 111 and 112, respectively. Compressed air is supplied to the valves 107 and 108 through an air conduit 113 which is connected to the air supply conduit 71 by means of tee fittings 114 and 115 and an interconnecting branch air conduit 116, as best seen in FIG. 4.

The pleat pressing clamps 7 and 8 are each held in the open or disengaged position 117 by means of a compression spring (not shown) within the respective air cylinder 102 and 103 which retracts operative parts of the respective air cylinder 102 and 103 when the cylinder is void of compressed air. The pleat pressing clamps 7 and 8 are movable from the open position 117 to engaged or pressing positions 118 and 119 engag-' ing the expanded and retracted positions of the expansible form 5 respectively, as best seen in F105. 1, 4 and 6.

The vertical rise of the expansible form 5 between the retracted position and the expanded position is commensurate with the vertical rise of the pleat pressing clamps 7 and 8 between position 119 and position 118. There is no vertical overlapping or underlapping of the pleat pressing clamps 7 and 8 in respect to the expanded or contracted position of the expansible form 5, thereby providing means for maintaining the expansible form 5 and the pleat pressing clamps 7 and 8 coordinated and in exact alignment, in all respects, one with the other in all of the pressing positions of their movements by the particular use and arrangement of the parallel

form expansion arms

57 and 58 and the parallel

pleat clamp arms

97 and 98, as best seen in FIG. 6.

The pleat supporting and pressing sections B and H of the expansible form 5 will automatically be in line with, and in the proper position behind, the pleats of trousers regardless of the size of the trousers placed on the expansible form 5, as previously described. The pleat clamps 7 and 8 will also automatically be in alignment with the expansible form sections B and H of the expansible form 5 and with the pleats of the trousers regardless of the size of the trousers under treatment.

A control panel 120 is mounted on the front of the upper support portion 4'and has electrical pushbuttons 121, 122 123, 124, 125 and 126 for controlling the operation of the garment treating apparatus 1. A series of

foot pedals

127, 128, 129 and 130 aremounted in the lower front of thestand 2 where they are in easy reach of an operator. Each of the foot pedals 127 to 130 inclusive is operatively connected to a suitable electrical switch (not shown) mounted within the forward portion of the stand 2 and the switches are operated individually by their respective foot pedals during use of the garment treating apparatus 1. Y Y

The pleat pressing clamps 7 and 8 are controlled by the pushbuttons 121 to I24, inclusive. When the pushbutton 121 is depressed, the solenoid 109 will be energized, thereby opening the air valve l07admitting compressed air into the air cylinder 102 to expand same to move the pleat clamp 7 to close against the face of the expansible form 5, as shown in FIG. 1. And simultaneously, with the energization of the solenoid 109,.the electric'circuit to the brake 70 will be closed, thereby locking the expansible form 5 in position. When the pushbutton 122 is-depressedfthe solenoid 110 will be energized, thereby returning the air valve 107 to the'closed position and exhausting theair cylinder 102 thus allowing the air cylinder compression spring (not shown) to return the clamp 7 to the open or disengaged position 117, and simultaneously with the depression of the pushbutton 122 the electric circuit to the brake 70 will be opened.

Pushbutton 123 is operatively connected to solenoid Ill and pushbutton 124 is operatively connected to solenoid 112 for controlling the air valve 108 to provide a similar action of the pleat clamp 8 on the directly opposite side of the garment treating apparatus 1. The pleat clamps 7 and 8 may be operated individually, and the expansible form 5 will remain in a locked position as long as either or both of the pleat clamps 7 and 8 are in an engaged or pressing position.

The foot pedals 127 to 130 inclusive are operative to control the contraction and expansion of the expansible form 5 for loading a garment-thereon. When the foot pedal [27 is depressed its respective electric switch (not shown) within the stand 2 will be caused to close and will: l energize the'sole-' noids' 110 and 112 thereby releasing the pleat clamps 7 and 8 -(if closed) and simultaneously unlocking the expansible form 5 (if locked); (2) energize the vacuum control solenoid 55 thereby introducing a vacuum within the air bag assembly 10, and simultaneously energizing a time delay segment 131 which will, after a few seconds delay, energize the form control solenoid air valve 72' thereby admitting'cornpressed air to the air cylinder 61 causing the expansible form 5 to retract to its minimum size, and simultaneously, with the retraction of the expansible form 5, the vacuum will cause the air bag assembly 10 to be gathered in folds within the expansible form 5 as the form is brought into a retracted state for loading a garment thereon.

Depressing the foot pedal 127 will cause the pleat clamps 7 and 8 to open (if closed); will cause the expansible form 5 to be unlocked (if locked); will cause the expansible form 5 to fully retract; and will cause the air bag assembly 10 to be gathered in folds within the expansible form 5 as the form retracts. When the foot pedal 127 is released, the vacuum will be shut off, the form will expand. the pleat clamps 7 and 8 will remain opened, and the expansible tom 5 will remain onlocked.

Contraction and expansion of the expansible form 5 for removing a finished garment from'the garment treating apparatus l is controlled by operation of the foot pedal 128.

- vacuum is not desired when removing a finished garment from the expansible form 5 as the vacuum may tend to draw the pockets of the garment into the spaces between the expansible form sections where they could become ensnared as the expansible form 5 retracts.

When it is desired to presteam the garment 6, the operator may select either of two means which areprovided in the garment treating apparatus 1: (l) the operator may depress the foot pedal 129 which will close its respective electrical switch (not shown) within the stand 2 thereby'energizing the magnetic steam valve 48 discharging steam into the expansible form 5 and air bag assembly 10; or (2) the operator may use the automatic means for presteaming the garment by depressing the pushbutton 125 which will cause a preset elec trical timing device 132 to be energized, which will, in turn, energize the magnetic steam valve 48 for a predetermined length of time; thus the operator may absent himself from the garment treating apparatus 1 during the presteaming cycle. When either the foot pedal 129 or the electrical timing device 132 are in use, the brake '70 will be energized also, thus locking the expansible form 5 in position during the presteaming operation in order to prevent stretching or distorting the garment 6.

lt is desirable to draw the pleat portions of the garment 6 into firm engagement with the respective areas of the expansible form 5 prior to operation of the pleat clamps 7 and 8, therefore, when the foot pedal 130 is depressed, its respective electrical switch (not shown) within the stand 2 will be closed and will energize the vacuum control solenoid 55 thereby introducing a vacuum into the expansible form 5 and air bag assembly 10 for the purpose of holding the pleats of the trousers fast against the face of the expansible form 5 prior to closing the pleat clamps thereon, as will be later described.

Automatic steaming and drying operations are controlled by anautomatic timing device 133 in the garment treating apparatus l, and the automatic timing device 133 has two phases of operation and will be started by depression of the pushbutton 126. The first'phase of the automatic timing device 133 is thesteaming cycle wherein the timing device 133 will energize the -magnetic steam valve 48 and the brake 70 thereby discharging a blast of steam into the expansible form 5 and air bag assembly 10 and simultaneously locking the expansible form 5 in position, and at the end of the first phase the automatic timing device 133 will interrupt the current to the steam valve 48, thus terminating the steaming cycle.

. The second phase of the automatic timing device 133 is the static air cycle wherein the automatic timing device 133 con tinues current to the brake 70, thus keeping the expansible form 5 in a locked position during theair cycle, and simultaneously the automatic timing device 133 energizes a blower motor 134 and the damper control solenoid 19, thereby discharging heated air into the expansible form 5 and air bag assembly 10 for drying and setting the trouser top. Near the end of the second phase, the automatic timing device 133 interrupts current to the blower motor 134, the damper solenoid 19, the brake 70, and will energize the solenoids and 112,

- thereby releasing the pleat clamps 7 and 8 (if closed) and at the end of the second phase the automatic timing device 133 shuts itself off automatically.

It is to be understood that all necessary electrical wiring, switches and controls which are not illustrated shall all be of conventional design and manufacture and, therefore, an illustration thereof is not considered necessary for the purpose of the present disclosure.

When idle, the garment treating apparatus 1 has the pleat clamps 7 and 8 in the disengaged position 1 l7 and the expansible form 5 in fully expanded state, therefore, in placing the garment treating apparatus 1 in operation, the operator will have the trousers to be treated in hand and will first adjust the controls 7'- and 8' to'select the temperature for the heaters 101 of the pressing clamps 7 and 8 respectively, if the garment 6 has pleats, and then depress the foot pedal 127, thus bringing the expansible form 5 into a fully retracted state, as previously described, and the trousers 6 are then slipped over the expansible form 5 and the foot pedal 127 is released, thus allowing the expansible form 5 to expand to the corresponding size of the trousers placed thereon. Then, if necessary, the trouser top may be presteamed by either of the two means previously described (depression of the foot pedal 129 or the pushbutton 125); thus if the trousers are badly wrinkled, this presteaming will relax the fibers of the garment and allow same to drape properly on the expansible form 5. if the trousers are of the pleated variety, the pleats are then adjusted on the face of the expansible form 5, in sequence, and the pleat clamps 7 and 8 are closed thereon by depression of the pushbuttons 121 and 123. The vacuum may be employed in this phase of the operation, as previously described, by depression of the foot pedal 130. The pushbutton 126 is then depressed, thereby inducing the automatic steaming and air drying cycle, as previously described, and during which time the operator may absent himself from the garment treating apparatus l, for example, to press the legs of a previously topped pair of trousers on another machine At the end of the automatic steaming and air drying cycle the trouser top will be finished and ready for removal from the garment treating apparatus l, and the operator will then depress the foot pedal 128, thereby unlocking and retracting the expansible form 5.

as previously described, and at which point the topped trousers may be easily slipped from the garment treating apparatus l, and upon release of the foot pedal 128, the expansible form 5 will again expand to its fullest degree where it will be ready for reloading, and the cycle of operation may be repeated.
