12 Claims.

The invention relates to novel and improved apparatus for drying or finishing articles of clothing of the general nature of shirts, coats or other body garments. It particularly relates to apparatus for air drying or steam-treating such garments and for producing an ironed or pressed appearance without resort to the usual pressing or ironing apparatus, and without employing internally expanding, permeable bags or forms of similar nature.

One object of the invention is to provide novel and improved means for closing, securing and retaining coats, shirts, or similar garments in dressed position while air or steam is applied to the interior. thereof.

A further object of the invention is to provide apparatus of this nature wherein means is provided for supplementing the drying effect in the immediate neighborhood of reinforced portions of the garment, or portions such as pockets and the like where two or more layers of material are superposed.

A further object of the invention is to provide apparatus of the above nature embodying means for producing a pressed or finished eiiect especially in certain locations in the garment, as will appear.

A further object of the invention is to provide apparatus of this nature including expandible means located internally of the garment and operatively linked with clamping means located externally of the garment for securing and simultaneously sealing open terminal portions of the garment, such as the tail or skirt portion of a shirt or coat, whereby air escape through the bottom opening is substantially eliminated.

A further object of the invention is to provide apparatus of this nature for the finishing of shirts, coats or the like embodying means for clamping the front open edges of the garment and additional means for clamping the collar portion oi. the garment, said several means being operatively associated, whereby operation of one clamping means produces operation of the other clamping means, with respect to both attachment and detachment of said several clamping means.

Other objects and advantages will be apparent on consideration of the following description in connection with the accompanying drawings, wherein Fig. 1 is a front elevation of an apparatus illustrating one embodiment of the present invention, parts being broken away.

Fig. 2 is a horizontal sectional view taken on the line 2-2 of Fig. 1; Fig.3 is a vertical sectional view taken on the line 3-3 of Fig. 2;

Fig. 4 is a. top plan view of the upper portion I of the apparatus;

Fig. 5 is a sideelevation of theapparatus;

Fig. 6 isa view corresponding to the lower portion of Fig. 5, but with parts removed to show the cabinet interior;

Fig. 7 is a vertical sectional view taken on the line 1-1 of Fig. 1; and

Fig. 8 is a horizontal sectional view taken on the line 8-8 of Fig. 5.

Before proceeding to a detailed description it may, be pointed out that the invention, while applicable to the drying and finishing of various types and styles oi garments, is particularly suited to the drying and finishing ofv heavier types of shirts, such as those worn by soldiers, sailors, or industrial workers, and the invention will be described in connection with a shirt of -this nature, it being understood that the description and drawings are presented for purposes of illustration merely, and not of limitation. Those skilled in the art, on consideration of the present specification and drawings, will is supplied directly to the shirt interior under a pressure sufficient to cause the air to permeate and pass through the single ply portions of the fabric. To insure the production and continuance of pressure above atmospheric during the drying period the neck, cuffs, and lower extrem ities of the shirt are substantially closed by being secured around suitable portions of the apparatus, aswill appear. Additional equipment" is provided for directing auxiliary air streams against double or multiple ply portions of the garment not so readily penetrable by air, such as shoulder straps or breast pockets.

Apparatus heretofore devised has been limited either to the use of a hollow dummy or form over which the garment was dressed, or a collapsible.

bag has been inflated within the garment, both the dummy or bag being foraminous to permit air to be blown outwardly therethrough. 'In any of the prior methods it has been difficult to solve the problems arising from attempts to accommodate a single such meansto a variety of garment sizes. This problem ishere solved in an effective manner by entirely dispensing with such dummy or bag, and providing improved apparatus which permits the garment, so to speak, to be substantially self-sustaining under the influence of internally applied air pressure. With this general foreword we proceed to a specific description of the apparatus shown in the drawmgs.

In the apparatus now to be described we show conventional means for heating a volume of air and supplying it to the garment interior under a pressure sufficient to balloon the garment and render it self-supporting. Th apparatus comprises a base l which carries the shirt supporting apparatus. The base In is a-hollow cabinet within which is located a motor H and a blower |2, both of conventional character. The blower delivers an air blast upwardly through heating chamber |3 communicating with a suitable aperture in the cabinet top and therefrom to a stack M which forms the shirt tail supporting member, as will appear. ing chamber, air heating means is provided comprising a bank of steam pipes (Fig. 1) in series with a supply pipe l6 and a return pipe I! (Fig. 5). i

The shirt supporting means will first be generally identified. It comprises an upright memher or post 20 constituting a'shirt front support, a pocket drier 2| carried by the upright 20 at an intermediate height thereon, collar supporting and clamping means 22 carried at the top of upright 20, right and left shoulder strap driers 23 associated with the collar support, a pair of cuff supports 24, and shirt tail clamping means 25 which cooperatesv with the shirt tail support or stack I4 already mentioned.

The shirt front supporting post 20 (Figs. 1, 2, 5 and '7) comprises two vertical members consisting of a flat rear plate or strip 30, and a complementary front plate or strip 3|. A portion of plate 3| is channeled at 32 so that when said plates are assembled they define therebetween a Below the stack, in the heat-.

vertical recess which houses a slidable bar 33 tical height with a plurality of pairs of slots 38,

each such pair being spaced respectively one each side of the vertical center line of plate 3|. The purpose of these slots is to permit limited upward and downward travel of wedge shaped lugs 40 which are carriedby sliding bar 33 and which respond to the operation of said bar 33 when handle 31 is raised or lowered. Each pair of lugs is so disposed as to abut, over a portion of the travel of bar 33, a clamping bar 42. A stud 43 (Fig. 7) is amxed to plate 32. The clamping bar 42 is provided with an aperture to receive stud. 43 in sliding relationship, the bar 42 being Thefront plate 3| is slotted biased towards plate 3| by means of a spring 44 r the inner end of which abuts bar 42, and the outer end of which is retained bya collar 45 fixed to stud 43. The clamping bar is thus normally biased towards contact with plate 3| but when sliding bar 33 is moved downwardly (from the dotted line position to the full line position of Fig. 7) by means of handle 3| so that the wedge shaped lugs 40 abut bar 42 in cam-like fashion,

the clamping bar 42 is moved outwardly toward clamp release position away from plate 3|. Four such sets of clamping bars are provided in the embodiment herein shown, as best seen in Figs. 1 and 5.

The lateral recessed edges 50 of plate 3| (Fig. 2) are each provided with a card cloth strip 5| extending substantially the full vertical length of upright member 20, and adapted to retain, respectively, the button strip and button hole strip of the shirt front edges. From the description so far, it is apparent that when a shirt is dressed on the apparatus, as indicated by the broken line outline in Fig. 1, handle 31 is lowered to disengage the clamping bars 42, the shirt edges are impaled on the card cloth strip 5|, and handle 31 is then raised to permit the free ends of bars 42 to move inwardly into clamping engagement with said shirt edges.

The pocket drier (Figs. 2 and 3) consists of a hollow casing assembly carried by upright member 2|] and comprising a fixed central body portion 53 and movable right andleft arm portions 54, the right and left portions being substantially identical in construction and function. The front plate portion 32 and the bar 33 are slotted at 55 (Fig. 2) to permit passage of air therethrough and into casing body 53 and thence to arms 54. Arms 54 are hingedly connected, at 53, to body 53, and are biased by means of spring 51 towards contact with the pocket portions of the shirt, in the full line position, Fig. 2. The spring is supported by a rod which extends through lugs 58 in casings 54. The interior surfaces of arms 54 are provided with an aperture 60, partially closed by a depending flange 5| (Fig. 3). When the shirt is ballooned by pressure applied internally thereof, the. pocket portion is forced against the interior face of arm 54 and the pocket flap abuts flange 6|. In the meantime the hot air passes through aperture 55 and into body 53 and thence to arms 54 so as to impinge on the pocket exterior. Some of this air is forced upwardly between the pocket and the customary pocket flap, along the line indicated by the arrow 62, Fig. 3. As a result the pockets and flaps receive a drying effect both interiorly and exteriorly thereof, and the pressure of each flap against its supporting flange 3| produces a finished effect on the flap.

As best seen in Fig. 5, an upright pipe forms part of the steam supply system. At its upper end it is capped, and supports a stub post 35 which carries means for expanding a collar support now to be described. The collar support comprises a resilient curved metal plate 61 bent as shown in Fig. 4; It is fixed to the top end of upright assembly or standard 20. It is provided with expanding means comprising a handle 10 secured by a set screw 1| to a sleeve 12 which rotates freely on post 66. The enclosure bounded by plate 6'! is substantially closed by a top plate 13. Sleeve 12 has a pair of opposed, perforated ears 14. connected, respectively, at one end to ears 14 and at the other end to similar ears 16 on the inner surface of plate 61. It is apparent from a glance at Fig. 4 that movement of handle 10 from the full line position to the broken line position exhands or moves apart the terminal portions of plate 67 so that means is thus provided for accommodating or adjusting the collar support to varying collar sizes. The handle may be held in any one of a succession of positions by a detent track 11. When a shirt collar is dressed around A pair of links 15 are pivotally the collar support, a series of perforations in plate 6! permits access of heated air to the collar of the shirt.

Escape of air through the collar opening is prevented or impeded by top plate 13, except through the curved shoulder strap heating tubes 23, through the end of each one of which a stream of heated air is directed downwardly upon the strap beneath it.

A bell crank lever having a clamping arm 80 and an operating arm BI is pivotally mounted at 82 on the upright 20. Arm 8I responds to operation of a toggle assembly 83, the knuckle of which is connected to one end of a link 84, the other end of which is connected to a lug 85 on sliding bar and the bar 33 first is depressed to release and then is raised to permit clamping engagement of breastv clamps 42, the same motions actuate the toggle 83 and consequently the collar clamp 80 first to release it and then to engage it with the collar wings and retain the collar in dressed position. A biasing spring 81 tends to move the clamp toward collar engaging position.

Two cuff and sleeve supporting members 24 are carried by rods 90. Since both such corresponding members and their supports are identical, one set only will be described. Member 24 (Fig. 1) is carried in loosely self-adjusting position on rod 90 which is mounted to turn at 9| on the lower lateral flange of a bracket 92. The upper lateral flange 93 is slotted to permit a certain amount of lateral play by rod 90, which, by reason of an outwardly offset center of gravity, has a tendency to fall to the full line position of Fig. 1. The cuff support'is carried on the upper end of rod 90 and comprises a wire mesh or perforate cylinder 94 closed at its outer end by an imperforate plate 95 (Fig. 5) and open at the inner end for communication with the space in the shirt sleeve. The shirt cuff is dressed on the cylindrical portion and is held there by a spring clamp band 96. The spring clamp at an intermediate polnt thereof is secured to cylinder 94 and retains the cuff in dressed position on the cylinder.

Cylinder 94 carries a plate extension 98 which is shaped and positioned to overlie the gusset portion of the shirt sleeve. When the shirt is dressed on the apparatus, and the cuff is clamped as described, the air pressure in the sleeve forces the gusset edges against the plate and thereby not only seals the gusset opening, but also improves the finish of the edges thereof.

Shirt tail supporting means I4 has heretofore been briefly mentioned. It comprises two, upwardly extending, complementary curved plates I and IOI' which are lapped at their meeting edges to define a generally oval enclosure forming a closed stack for heated air as previously disclosed. The overlapped edges are slidingly fitted so that the support I4 may be increased ordecreased in horizontal sectional area as will bedescribed'. Sliding motion is effected by movement of base plates I02 and I03'toward or from each other in track strips I04 -(Figs. 5, 6 and 8). 4

Each section of the tail supporting means is provided with a clamp. Both clamps are identical in construction, and one will be described (Real, 6 and 8). It comprises a lever H0 pivotally mounted at III on a bracket H2. The upper end of the lever has an arcuate shaped rod or member II3 which is arranged to engage in a groove I I4 in the stack when the clamp is applied. A spring H is provided to normally bias the clamp to closed position. The lower end of the lever H0 is connected by a link IIG with one end of a pivotally movable lever Ill. The other front of the apparatus and is bent at the region 33. When'a shirt is dressed 0n the apparatus,

of contact with handle I20 so as to'retain the handle in clamp-release position. When the latch I2I is released, the springs H5 (Fig. 1) move the clamps H3 toward clamping position, and initiate movement of handle I20 in a clockwise direction, Fig.. 1. Further movement of handle I20, manually, in a clockwise direction expands th two sections I00 and IOI within the shirt tail portion until this part of the garment is fully extended as limited by the shirt size. This, in con- -junction with the fact that the shirt extremity is supplied and distributed through a perforated pipe I25 which is in communication with the steam inlet line I6 through a branch line I26 under control of a valve I21 and thenceto a waterseparator I 28 and therefrom through pipes I29 to the perforated pipe I25 (Fig. 6)

A valve I30 is operated by a lever I3I which in turn is manipulated by a pull rod I32 extending through the front of the cabinet and having a handle I33 for manual operation of the valve. It will 'be understood that when the handl I33 is pulled, steam is released through the perfora tions in pipe I25 which is situated substantially in the vertical center line of a garment dressed on the apparatus. Condensation on pipe I25 isprevented by disposing it in close proximity to pipe 65 which, as heretofore disclosed, is in communication with the main steam inlet, and is heated thereby. Pipe 55 is supported on a bracket 64. 7 When steam from the inlet is supplied to the air heating system I5 through valve I35, it is simultaneously admitted to pipe 65 (Fig. 5);

The curved member I36 guides the shirt while it is being dressed on the apparatus.

Operation of the device proceeds as follows. It is assumed that steam has been admitted to the heater I5 and to pipe 65 by valve I35 and that these units are at operating temperature. Handle I20 is moved counterclockwise to latched posi tion disengaging clamps H3 and retracting the shirt tail supports I00 and NI. Sliding bar 33 is moved to its lowermost position by handle 31, thereby releasing the breast clamps 42 and collar clamp 80, so that the button and buttonhole strips and collar can be inserted thereunder. Blower I2 is not yet in operation.

In dressing a. shirt on the apparatus the shirt tails are draped or drawn around the stack sections I and HH. Bar 33 is raised by handle 37, until the breast clamps engage the shirt front and the collar clamp 80 is urged to clamping position upon the collar front. Handle I is then moved clockwise until clamps I I3 clamp the shirt tails, and immediately thereafter stack sections 100 and I0! move outwardly until the natural resistance of the garment fabric prevents further expansion. The shirt cuff are next successively dressed on their respective cylinders 94 and are clamped by means of spring clamps 96.

The blower 12 now may be operated by starting the motor ll. A draft of heated air rises If the nature of the work requires it, or if desirable for any reason, steam may be directly applied to the garment at any desired stage of the operation, or as an independent operation, by manipulation of handle I33, operation of which distributes the steam throughout the chamber within the garment by means of pipe 125,

The garment having been dried or otherwise processed to the desired finish, the manner of its removal requires no further explanation, the above sequence of operations being reversed, both in chronological order and direction, although of course the specific sequence is not critical with respect to the order in which the dressing and undressing operations are performed.
