This invention is amethodof and apparatus for pressing, ironing, or otherwise shaping or forming articles, particularly articles of apparel, wherein the article is subjected to pressure between two relatively* movable pressure members.

In the artkof pressing, ironing, or otherwise forming or shaping articles of apparel wherein two relatively movable pressure o members are employed and the article is positioned between said members during the pressng operation, there are two essential factors Awhich have a vital bearing on the success and perfection of the operation.

These factors are uniform-heat and uniform pressure.

The prior art has developed satisfactcpzy methodsand apparatus for maintaining sub-` stantially uniform heat or' temperature of o the pressing members, but difliculty is still experienced due to the lack of proper apparatus or method for insuring a uniform prese sure throughout the entire surface of the ressure members. Numerous attempts have een made to solve this particular problem by padding the workin faces of one or both pressing members or y employing other types of yielding working faces for these members, but due to inherent characteristics of the structures previously proposed, none of them has provided the degree of uniformity as to pressure that is desired.I

This is particularly true of the so-called collar and cuff machines wherein the relatively movable pressing members have a marked degree of curvature. In machines of this type there are always certain portions of the surfaces of the pressing members wherein no' substantial degree of pressure is exerted and -at these portions the pressing or ironing operation is very unsatisfactory, generally resulting in a more or less rough dry appearance of the article.

With theses. facts in mind the present invention provides a method of and apparatus for pressing, forming or otherwise shaping articles of apparel and the like in a'manner such as to insure a uniformpressure through out the working faces of the pressure members irrespective of whether said members 1932. serial no. e 15,224.

are `substantially plane members or are provided with faces having substantial curvature. A

The invention has also for lits object the provision of a method and means for maintaining the fabric face of one or both pressing members substantially dry and to dispel the moisture accumulating therein from' a. dampened "garment during the pressing operation. y

`Another object of the invention is to provide'in' an apparatus of thetype described a-substantially slack outer covering for one Vor bothof the pressing members in combinaton with means for maintaining said slack covering smooth and devoid of wrinkles t all stages of the pressing operation.

\ Another object of the invention is toprovide an apparatus capable of quickly andV uniformly performing pressing or ironing operations in a manner proposed by my improved method. f

These and other'objects of the invention will become apparent from the following specication read in connection with the accompanying drawings wherein is illustrated a preferred embodiment of my improved apparatus. y

Fig. 1 is a side elevation of my improved apparatus with parts thereof in the normal position and with portions thereof broken away to expose normally concealed parts.

F ig. 2 is a fragmental sectional view of the stationary pressing member or buck of my apparatus showing the relative position 85 of the parts when the movable pressing member or head is in operative engagement with the stationary member.

Fig. 3 is a fragmental sectional view similar Y to that shown in Fig.` 2 but with the buck and 90 head in their s aced or openposition and J showing the re ative position of the cover member of the stationary pressing member during the drying thereo v Fig. 4 is a diagrammatic view of a basic 95 conception of the present method and apparatus.

Broadly stated, my improved method comrises positioning or, supporting an article to `be pressed between two, relatively movable Eessin'g members, one or both of which may heated, relatively moving said pressure members so as to contact opposite faces of the article and then developing pressure between the pressing members while maintaining the same relatively fixed with respect to each other. With this in mind considering Fig. 4 of the drawings, 1 designates a suitable base member upon which is supported a pressure member 2. The members 1 and 2 are relatively fixed with respect to eachother and are designed to cooperate with a relatively movable presser member 3 pivotally supported at 4 by any suitable means and normally urged away from the members 1 and 2 by suitable sprin' means 5. The member 3 may be maintaine in operative position with the members 1 and 2 and against the upward urge of the spring 5 by means of a suitable strut 6 pivotall supported at 7. Either or both of the mem ers 2 and 3 may be heated by supplying the heated `fluid thereto through the connections 8 and 9. In operation, an article to be pressed, such as indicated at 10, is positioned on the upper face of the member 2, the member 3 then brought into contact with the upper exposed face lof said article and maintained in said position against the upward urge of the spring member 5 by the pivoted strut 6 as shown. Fluid under pressure is then admitted by wa of the fitting 8 in order to slightly eXpandf e member 2 in a vertical direction in order to place a substantial and uniform pressure on the article 10, it being understood that the member 2 by reason of its slight expansibility will create a uniform pressure on the article against the lower face of the pressing member 3, said member being restrained against upward movement bythe strut 6.

While Fig. 4 illustrates the basic principles of my method and apparatus, I have shown in Figs. 1, 2 and 3 a more practical conception of my invention and one capable of practical commercial adaptation. Referring more particularly to these figures of the drawings, I have shown in Fig. 1 a machine comprising a base frame 11 on which is supported a standard 12 carrying at its upper end the relatively'fixed pressing member or bu k of my apparatus which is indicated generally by the reference character 13. Cooperating with the relatively ixed pressing member 13 is a relativel movable pressing member or head indicate generally by the reference character 14. The pressing surface of the head 14 includes depending side pressing portions extending substantially parallel to the path' of movement of the head with respect to the buck and these depending portions cooperate with similarly positioned portions on the buck in a manner to be hereinafter described. The relatively movable pressing member 14 is carf ried at the outer free end of a lever 15 pivoted at 16 to an upstanding portion 17 of the frame movable 11. The lever 15 with the relativel d' from oppressing member 14 is moved to an 'erative engagement with respect to the stacylinder 23 pivotall connected at `24 to the.

frame member 11. lidably mounted within the power cylinder 23 is a piston 25 carrying a piston rod 26 which extends thrugh the lower head 27 of the power cylinder 23 and is connected to the crank pin 20 for partially rotating the crank about its center 22. For the purpose of controlling the admission a'nd exhaust of motive fluid to the cylinder 23 a treadle mechanism 28 is provided for operatively controlling a valve mechanism generally indicated by the reference character 29.

The treadle mechanism 28 is pivoted intermediate its ends to one portion of the frame 11 as at 30 and is maintained in a normally elevated position by suitable means such as s'prin 31 interposed between the treadle 28 and t e sup-porting plane for the machine. In order to lock the treadle mechanism in depressed position against the tension of the spring 31 I provide a suitable latch memberr 32 pivotally connected asat 33 to a lug 34 carried by the treadle 28. The latch or trigger 32 is maintained yieldably urged against a locking shoulder 35 carried by the frame member 1l by a suitable sprinff 36 positioned between the treadle portion 37 of said latch and the upper face of the power treadle 28.

The opposite or inner end of the treadle member 28 is connected by a link member 38 to a valve operating lever 39 pivoted interl mediate its ends as at 40 to an upstanding lug 41 carried by the valve mechanism 29. The valve mechanism 29 comprises a casing 42 having a partition 43 which divides the casing into two compartments 44 and 45. The partition 43 Lis provided with a .port 46 with which a valve member 47 cooperates and -which is maintained in a normally closed position by means of a spring member 48 mounted upon the stem 49 ofy said valve. The upper wall of the casing 42 is provided with a port 50 leading from compartment 44 of the casing to the atmosphere and this port is controlled by a valve member 51 which is maintained in a normally closed position by means of aspring 52 mounted on the stem 53 The valve operating lever 39 is positioned toV engage the upper ends of the valve stems 49 andv 53 and is urged into position such that the valve member 51 is maintained, against the urge of its spring 52, in a slightl open position, with the valve 47 close his is accomplished by means of a spring member 55 tensioned between the outer end of the lever 39 and a xed part of the frame member 11 in a manner such as to urge the outer end I of the valve stem 53, allowing the valve 51l to close while simultaneously the other end of said lever depresses the valve stem 49, thereby opening valve 47 to allow motive iiuid' from compartment 45 to enter the power cylinder 23 through the conduit 56. This urges the piston 25 into the lower end of the cylinder 23 with the result that the crank 21 is rotated downwardly to exert a pull on the link 18 which brings the movable pressing member 14 into operative engagement with the stationary pressing member 13. In this position of the parts the trigger or latch 32 moves beneath the lockingshoulder 35 under the urge of the spring 36 and prevents the treadle 28 from rising under the urge of the spring member 31. "The crank 21 and the throw of the power operated piston are such that the crank is in a lower dead center position when the movable head of the press is in operative engagement with the buck. When the pressing operation has been completed a slight tap ofthetoe on the trigger release treadle 37 moves the trigger 32 from engagement with the shoulder 35 and the power treadle 28 rises under the urge of thespring 31 to restore parts of the valve mechanism 29 to the position shown in Fig. 1, in which the air or other motive fluid from the cylinder 23 will exhaust through the open port 50.

In order to restore Vthe lever 15 and the movable pressing member 14 to an elevated position the crank 21 is provided with a lateral extension 57 carrying a pin to which is connected a powerful coil spring 58, the opposite end of said spring being connected to a lug 59 carried by the arm 17 of the frame 11. Thus when the motive iu'id is exhausted from the cylinder 23 the spring 58 functions to raise the crank 21 and consequently exert an upwardly directed force on the link 18, which raises the lever 15 and the pressing member 14 to the position shown in Fig. 1.

In order to provide substantially uniform pressure between the relatively movable pressing members 13 and 14, I have devised an improved and novel head for one or both of the pressing members. In the accompanying drawings I have illustrated these improvements as applied to the stationary head or buck of my apparatus, but it is understood and will be apparent from the following description that the improvements are such that they may be associated with either or' both of the pressing members of the machine when and if desired.

Referring to Figs. 2 'and 3 of the drawings, have shown in section structural details of my improved pressing head. The stationary pressing head indicated generally lby the ref- -er'ence character 13 in Fig. 1 comprises a rigid base or' restraining member 60 which is secured by lag screws or the like 61 to the'` standard 12 of the machine, as shown in Fig.

1. The base or restraining member 60 may be of any desired shape and dimension corresponding to the character of the work to be operated upon, and is shown as being provided with an upstanding flange 62 which extends completely around the outer edge thereof. The upper face of the base or restraining member 60l is provided with spaced lugs or studs 63 which are of the same height or which extend above the surface of the member 60 an extent corresponding to that of the flange 62. The iange 62 and the pins or studs 63 cooperate to support a perforated plate 64 which is firmly secured to the base 60 by means of screws or the like 65 threaded into the studs 63 and the flange 62. As shown in Figs. 2 and 3, the screws 65 are preferably countersunk in order to maintain a substantially even upper surface for the perforated plate 64.

The perforated plate 64 is covered to a substantial thickness with a soft padding material such as indicated at 66, said padding being distributed over said plate in a substantially even layer, it being noted that the padding is preferably carried down over the vertical side faces 67 of the restraining base- 60. The Ipadding 66 just referred to is maintained in position by meansv of a flexible impervious sheet 68 extending completely across the member .60 from side to side and from end to end thereof,said sheet being secured to the under surface of the member 60 by any suitable means such as the cap screws 69 and cooperating plate or iange member 70. It will be noted that the plate or flange member 70 is dimensioned to extend laterally of the edge of the restraining member 60 to support the padding 66. and the sheet 4member 68 for a purpose 'to be more particularly referred to hereinafter. v

For purposes to be hereinafter explained more fully, the member 6 8 is a flexible sheet of material which is impervious to air and water and may conveniently be a closely woven fabric impregnated or otherwise treated to render the same impervious to air and water.

, The impervious sheet member 68 is preferably covered by an outer covering sheet 71 which may of cotton duck or the like, and

soy

while I have for-purposes of convenience and simplicity of illustration, shown this cover` in the drawings as comprising a single thickness of material, it is to be understood that this member may comprise one or more inner layers of soft flannel or the like and an outer layer of cotton duck s uch as is conventional in pressing andironing machines. The cover member 71 is, as shown, dimensioned so as to provide an appreciable slackness when mounted upon the stationary presser member of my apparatus and may be secured to the under face of the member in any suitable manner such as by plates 72 and cooperating bolts and wing nuts 73.

Due to the slackness of the cover member 71 just referred to, it is desirable to provide means for maintaining said cover member in an unwrinkled and substantially smooth condition at all times, and also I find it desirable to the end that moreperfect work may be accomplished by the machine, to provide means for maintaining this outer cover member substantially dry at alltimes. For this purpose I provide the restraining member or base 60 on its under face with a peripheral or annular rib '74: which is longitudinally cored throughout its length as shown at 75. The outer wall 7 6 of the rib .7 4 is provided with a series of perforations 77 communicating with the enclosed space defined by the cover 71. This' arrangement is clearly shown in Figs. 2 and 3 of the drawings. Into the cored rib 7 4 I direct a drying Huid by means of the 'connection 78 and I have found it convenient to employ a continuously operating air fan or blower 7 9, which as shown in Fig. 1, may be conveniently associated with the connection 78 by means of a conduit 80. Thus it will be seen that the air entering the coredrib 74; finds its way by means of the perforations 77 into the space confined by the outer cover member 71 so thatwhen the movable pressing memberof my apparatus is elevated as shown at Fig. 3, said air functionsto distend the cover member 71 throughout its entire extent, and such air passing relatively freely through said cover member tends to maintain the same substantially dry at all times. Furthermore, it will be seen that this same air, continuously permeating the cover member and maintaining it in a distended position,j:wlll function, when the movable pressurernember is associated with the fixed pressure' member, to draw the slackness of said cover to the outer edge of the head as shown Fig. 2. This operation functions to maintain said cover member substantially smooth "and free from wrinkles at all times.

A further feature of novelty of the present invention resides inthe means I have devised fordevelopng pressure between the relatively movable pressing members and an article positioned therebetween.'y Heretofore it has een ustomary to develop 'such pressure bv power-"means arranged to move the relatively movable pressing members forcibly together.

In other words, the ressure in the prior machines with whichl am acquainted has been developed by moving the pressure members relative to one another an extent sufficient-todevelop substantial pressure on the article by movement of the members. Contrary to prior practice in this 'respect I propose to position my relatively movable presser members in contact with the opposite faces of an article to be pressed while exerting little or no pressurez and then-maintain saidmembers in such position and, wh-ile restraining them `nipple 81 communicating with the interior of the space defined by said base member t 60 and the impervious sheet or cover member 68. The nipple 81, as shown in Fig'. 1, is connected by means of a suitable conduit 82 and valve mechanism 83, to a source of fluid pressure connected to a pipe line 84 and connected to the valve mechanism 83. The valve mechanlsm 83 is similar in all respects to the valve mechanism 29 and comprises an inlet valve 85 and an exhaust valve 86 operable through 'means of a lever 87 mounted on a bracket 88 carried by the valve casing 83 and engagin the upper ends of the valve members 85 an` 86. The lever 87 is maintained by means of a spring 89 in a position such that the valve 86 is sllghtly open and is moved against the tension of said spring into a position to allow said valve to close and to simultaneously open valve 85 by means of a set screw 90 adjustably carried by the crank member 21. As shown in Fig. 1, the relative positions of the crank 21 and the pin 91 and valve operating lever 87 are such that when the crank member 21 is in its lower dead center position, in which position the lower working face of the upper relatively movable member of my pressing apparatus occupies a position in substantial coincidence with the surface defined by the outer cover member 71 when the latter is in contact with the inner impervious cover member 68, as shown in Fig. 2, the set screw 90 contacts with the lever 87 to move said lever into such position that the exhaust valve 87 is closed and the inlet valve 8,5 is opened. Thus, motive fluid such as air under pressure is admitted into the interi-or of the lower stationary pressing member and tends to slightly distend the cover member 68. Thus it is seen that after the relatively movable pressing members of my uapparatus have been assoclated 1n a mannersuch as to `contact on opposite faces of an article to be vpressed, I expand or distend the working face j ofone or both ofsaid pressing members without relatively moving said members, and

'whileamaintaining said members relatively fixed. In this manner the Huid pressure adtially vertical faces of the pressing members in the region. of .the vertical face 67 lof the member 60. In all prior` machines known to me it has been impossible to develop in the region vorresponding to the one just designated, a proper and uniform pressure or one such that would yield a smooth and wrinklefree pressing operation.

When the pressing o eration has been completed and it is desire to remove the article from the press the treadle mechanism 28 is operated in the manner heretofore described which results in the crank 2'1 and its adjustable set screw 90 moving away from the valve operating lever 87 to open the exhaust valve 86 and close the inta valve 85. This relieves the:y pressure on th interior of the buck with the result that the movable head may be Withdrawn without possibility of rupturing the exible sheet 68. It will be noted that this operation is accomplished in the proper timed relation due to the adjustability of the set screw 90 and the fact that at\the time the crank 21 begins its movement away from the valve operating lever 87,k it is moving rapidly relatively to the speed of upward movement of the link 18. This design and arrangement of the'parts insures the proper Vtimed operation of the valve operating lever 87 both 1n opening and closing movements of the press.

While either or both of the pressing members of my machine may be heated, I find it convenient and desirable to heat only the upper or relatively. movable member of` the machine and this may be accomplished in any conventional manner such as by leading to the interior of said member steam or other heating fluid. In Fig. 1 I have shown a heating Huid conduit 91 to which the fluid may be suppliedto the head 14 through a conventional hinged joint 92.

Referring to the purpose and function of the extended plate or flange 70 associated with ,the means bv which .the impervious sheet issecur'ed to the under face of the buck 60, it will be seen that these platesextending laterally to support the padding 66 and impervious sheet 68,' -functionwalso to prevent rupture or puncture of the sheet when air is admitted to the interior of the stationary head, it being noted that if these portions of the sheet were left unsupported, the pressure within the fixed head would be unresisted at these portions during the pressing operation. Another important feature of the present invention resides in the fact that the repeated delivery of air to and exhaust of air from the interior of the buck maintains the'padding material 66 in a fluffy and non-impacted condition. This insures a yielding pressing face on the buck at all times.

It will be understood from the foregoing description that the apparatus forming the' subject-matter of the present invention is arranged and designed such that the relatively movable pressing members of the apparatus are movable into a position in which they contact an article positionedtbetween them on opposite sides with but little or no pressure. The members are then relatively fixed in such position and by expanding or distending the working face of one'or the other of said members, pressure is developed within and between the otherwise fixed-pressing members. In` order to accomplish this operation the flexible impervious sheet 68 must be capable of 'slight expansion or distension when air is admitted to the interior thereof and this may be provided by making the sheet inherently slightly extensible or fitting said sheet over the soft padding 66 snugly but in amanner to leave a slight degree of slackness therein.

It is preferable to provide a very slight degree of slackness in the sheet 68 so that when pressure is applied to the interior of the buck with the movable pressing head `in operative pressing engagement therewith, the relation and operation of the members is similar in all respects to that of an inner tubewithin a tire casing.

From the foregoing description read in connection with the accompanying drawings, it is apparent that I have provided an improved method of and apparatus for pressing, ironing or otherwiseY shaping or' forming articles, particularly articles of apparel, wherein ajsubstantial and uniform pressure may be developed over the entire moving face of relatively movable pressing members between which the article is positioned. Furthermore, the invention provides means for maintaining the outer covering of one or both pressing members substantially dry at all times and free of wrinkles. It is to be understood that while I have chosen to illustrate the invention as embodied in an ironing machine, neither the methodl nor the apparatus is restricted to such use, but are both generally applicable to ironing machines, pressing machmes, and

los

generally al1 forms of garment shaping and able pressing members are employed for operating upon an article positioned between the same.
