My invention relates to anirnproved form of apparatus for drying and pressing" hosiery. j u

.Heretofore 1n the drying-and pressing of hosiery, as a step 1n its manufacture, after .the dyeing operationit has been customary to place the hosiery on hollow steam heated` `forms or boards on which'it is allowed to remain until dry, or, alternatively, toplace it `upon solidforms or boards and subject the hosierythereonto external heat. -f

It has `been .found that While. the hollow Vform method of drying and pressing is sub-` stantially satisfactory, it is lopen to a num-V ber of objections. The use of solid formsy l subjected to Yexternal heat has heretofore proved rather less satisfactory, since .the meansprovided for supplying and subjecting the forms to heat have been cumbersome to handle, more or less complicated inconstruction and expensive to provide and maintain.Y Further, it may be said that'such apparatus has not proved of great eihciency, j

with the result that the majority of manufacturers `have within the last few years utilized the hollow forms.V Y Y.

Y Now theobl'ect of my invention is to pro-` videfan improved. apparatus, using solid forms and provided with means `whereby vhosiery on the forms will be subjected to j external heat andpressing action.

Further objects of my invention are `to "provide an apparatus which will be semiautomatic :in operation, so arranged as to give a maximum of eficiency both .from the4 standpoint: of results obtainable and from the standpoint of labor and maintenance econonly, and at the/same time anapparatus which will be simple and economical.of"construe tion and operation witha maximum of dul rability and efiiciency.

Having indicated, `in general, way, the

` nature, puIPOSe and advantageof my inven-V drawings inwh-ich l'have illustrateda pre?,

`ferred embodiment, 'and inV whichf tion, l `will proceed to,y detailed `description thereof, with `reference :to 'the accompanying Fig. `1 is ,af view of apparatus embodying "my inventionf'in" elevation, and partly out ilfWlYf V Y i l 1924. serial No. `710,241.v

Brackets d span beneath the slots c and serve to maintain the integrality of the table. j j f Slides e, e, of a length of two thirdsthat Vofthe table, aremounted in the channels and retainedtherein by plates Lg, g, as shown in Fig. 3. `Solid forms or boards `f are mounted at intervalson the slides'e, e.

Centrally of the table `between the slides i e, `e, and extending longitudinally a distance equal to a third` o f the table length, is .rigidly mounted, on suitable brackets, avertically extending hollow plate 7L, the side walls fof which areperforated and within which `is a steam coil u f f i OnV opposite sides of the plate k areposi- 'tioned vertically extending Vhollow plates j,

y', the inner `walls of whichfare perforated,

while `the outer walls are insulated with insulating material 7s. Within each `of the plates y', j is a steamcoil Z. The bottoms of the plates j, j rest upon longitudinally eX- tending brackets m, while the Vplates are supported in vertical position by meansof arms n, n pivotallyattachedto the outside walls thereof and to cross membersjo supported abovethe chambers by standards29.1 i

indicated by the valved pipe t, which is connected to coil z' and at its ends, through flexible pipes u, u, with the coils Z in plates the toggles through rollers carried by, and

extending laterally from, the links; springs s, .e being provided and lacting to tend to For straightening the toggles and moving the plates j, y' toward each other, there are provided foot levers Z, Z pivoted to a cross member 2 and to which the links w, w are pivoted, whereby the links may be moved downwardly, as will be understood from inspection of Fig. 2.

Beneath the middle portion of the table Yand plates t and y', j is a fan msiilg 3, the

bottom of which is provided with a shutter operable by a handle 4; and within which is a motor driven fan 5.

Beneath the table is positioned an electric motor 17 connected by means of a chain 6 and large sprocket 7 to a shaft 8, which in turn carries a pair of small sprockets 9 connected by chains 10 to sprockets 11 on transverse shafts 12 respectively mounted beneath the table a. Chains 13 carried by sprockets 14 mounted beneath the table and sprockets respectively carried b v the shafts 12 are positioned beneath the slotted channels in the end sections of the table respectively and are adapted to move the slides upon which the sets of forms are mounted through the medium of upwardly extending lugs 15, earried by the chains 13, respectively, and engaging between downwardly depending lugs 16 carried by the slides, respectively, adjacent their ends, as will be seen from an inspection of Fig. 1.

As shown in Fig. 1, one of the chains 10 is crossed so that whichever way the motor 17 is driven the chains 13 will be driven in opposite directions, as indicated by the arrows i'n Fig. 1.

The motor 17 is manually cont-rolled for starting by means of a switch 1S, suitably mounted on the table and adapted for two positions to connect the motor with current in opposite directions to effect its rotation in either direction, as will be seen from an inspection of F ig. 5, from which it will be noted that if the switch is thrown to close the circuit across the points 19 the motor will operate in one direction, while if the circuit be closed across the points 2O the motor will. be reversed.

The motor is adapted to be automatically stopped by means of switches 21, 21, respectively adapted to open the two circuitsI in which the motor may be placed by manipulation of switch 18. rlhe switches Q1, 21 normally retained in closed position by springs 22, 22 are positioned respectively at opposite ends of the desired travel of the lugs 16 carried by one of the slides e, so that as the slide reaches one eXtreme or the other, one of the lugs will contact with one or the other of the switches and open it, breaking the circuit and stopping the motor, which may then be restarted in the opposite direction by throwning switch 18.

In practice, the apparatus illustrated and described includes twenty-four forms consisting of two series of twelve forms each comprising two sets of siX forms mounted on each of the slides c and the various parts are so arranged that one set of six forms from each series will be within the drying chambers between plate 7L and plates j, j, while one set of six forms from each series will be without such chambers at opposite ends of the table a.

Assuming now that the parts are in the position shown in Figs. 1 and 2 and the apparatus is to be put in operation, steam is turned into the coils in plate /z and plates j, and operators place hosiery to be dried upon the sets of forms at opposite end portions of the table. Plates y', j are moved laterally away from plate 7L by raising levers m, which causes the toggles to bend.

The motor is then. started by throwing switch 1S and the slides caused to be moved longitudinally in opposite directions with the result that the sets of forms carrying hosiery are moved oppositely into the drying chambers between the plates, while the sets of forms occupying such chambers are moved oppositely out of the chambers to the end portions of the table. Zhen the two sets of forms upon which the hosiery has been placed are fully within the chambers between the plates, the motor is automtically stopped through the opening of one of the switches E21, as described.

The plates j, y' are then moved toward the plate 7L by manipulation of the foot levers Z, Z, which straighten the toggles, and the hosiery on the sets of forms within the chambers between the plates is subjected to the heat from the coils thereinpassing through the perforated walls thereof and it is also pressed between the walls. The fan 5 is started and the shutter adjusted by manipulation of han dle 4 so as to withdraw from the chambers between the plates any steam which forms in the drying of the hosiery. The plates j, y' may be moved together and permitted to remain during the drying operation or they may be manipulated back and forth. During the drying operation, wet hosiery is placed on the sets of forms occupying the end portions V the plates y', y' are moved outwardly, the motor of the table. When the drying is completed,

17 started and the sets of forms withV dry hosiery moved oppositely out of the drying chambers to the end portions of the table, where the dried hosiery is slipped therefrom and wet hosiery is placed thereon, while the sets of forms upon which wet hosiery has been placed, as above described, will be moved oppositely into the drying spaces.

It will be understood that I do not'intend to confine myself to the details of the apparatus above d-escribed, as they may be varied' Ain many respects without departing from the spirit of my invention. Y
