i ToaZZ whom 'it may concern:

` speci Be it known that I, JACOB GERRiTsoN, citizen of the United States of America, residing at Kankakee, in the county of Kankakee and State of- Illinois, have invented certain new and useful Improvements in.

Hosiery Drying and Shaping Structures, of which the following is a specification, reference being had therein to the accompanying drawing. I

This invention relates broadly to hosiery dryin and shaping structures, and more cally to a fabric-holding device which is attachable thereto for preventing the natural shrinking or creeping of hosiery after being placed upon the drying structure and while the moisture therein 1s being evaporated therefrom.

The present invention involves an improvement upon and an advance over the particular device disclosed in U. S. Letters- Patent 1,279,332, granted September 17 1918, to L. F. Gray, L. Wedge and E. Giese. The structure of that patent has, in practical use, been found to be exceedingly useful and efficient; but it has been discovered, in attaching the pile-including fabric Aby silicate of soda (as a binder) to a heated form, rthat thisfsubstance tends to affect the texture `of the fabric arid thereby reduces its serviceability. The presentinvention is predicated upon the recognition by me that` it is desirablein fact rather necessary-to treat the fabric itself (in a manner to ,be

explained hereafter) before applying it to the form; and, in addition, to interpose a separating element or structure, between the fabric and ythe form, this separating structure constituting, also, an efficient' support for the fabric and also a binding-instrumen-r tality between the fabric and' the form.

As a result of considerable experimentation, I have found that if the fabric is 4treated with somesubstance-such as a sizing made, say, from a flour paste or {luidandif one or more backing' sheets or pieces of material-such asasbestos paper, also similarly sized-are employed, and if, then, the backing sheets and fabric be attached to the form-preferably while the latter is in a heated condition-with a cementitious substancesuch Mas liquid-glass (silicate of soda) or a mass which includes (in major or minor proportions) silicate'of sodathe device thus constituted may be most securely i structure (including the several specified' i elements) is not only rendered. highly efficient as a fabric-holding device, but becomes one which will endure for a considerable period. It is to be understood that the selection of the particular fabric is more or less dependent upon the proposed conditions of use; but, as I am at present advised, it is to be understood that a fabric which Vincludes a base or body portion and a pile that has a tendenc to lie down flat when brushed or rub ed in one way but which will stand out at an angle from the bodyportion and present a multitude of fabricgri ping fingers or points when brushed or rub ed in the opposite direction, may be ed may be of any appropriate material, i

shape and dimensions; but, as the dryingform upon which the holding-structure 1s `mounted becomes considerably heated in use, a material which includes asbestos is very desirable and efficient. A material which is conveniently manufactured, procured and applied, and one,\well adapted for the purpose, is -a so-called fire and ydamp- Vproof asbestos paper, of suitable thickness and dimensions. The number of layersof the paper is, perhaps, largely one of choice, so long-as these do not act as a heat-insulator; but, if the sheets of paper are formed and aggrouped in the manner hereinafter explained, two of these sheets will be found su cient and, besides, each of these functions in a novel and desirable manner.' The cementitious mass by which the structure is secured t0 the form may be any appropriate adhesive; but, I have found that a cement which is composed of or which includes silicate of soda (liquid-glass) especially is well. adapted for the piirpose. For ordinary ur- `poses, commercial liquid-glass will su ce; ut I have, myself, also devised an exceedin ly eiicient binder in the form of a cementitios mass which preferably includes silicate of soda, and it is to be understood that the term cementitious mass, where hereinV specified., refers to either of. these adhesives as well as 'any other suitable for the endin view. y

In order thatthe invention may readily be comprehended, 'both as to its 'constructionand as to the manner of its application to drying and shaping forms, I have, in the accompanyin drawings, illustrated Various tpes thereo and it is to be understod t at these are merely illustrative and that 'such types as are here shown are susceptible of a wide range of modification and variation without departing from the spirit of the invention or sacrificing any of its salient 'features and underlying principles.

In these. drawings, the reference-numeral 1 designates a so-called Paramount hosiery drying and shaping formas constructed and exploited under U. S. Patent No.

1,207,496, granted December 5,. 1916. This form is hollow to contain a heating medium whereby heat is thereby' applied to the in? ternal surface ofthe fabric of the hosiery, designated generally bythe reference-numeral' 2. This form has fabric-smoothing and flattenin sides 3 which, in this instance,v are s own -as arc-shaped and as merging into reduced or creaseeforming edges 4. The form, itself, is provided with a base 5 by which it is mountedA upon a pipe 6 for conducting a suitable thermal fluid to the interior of the form froma suitable source of supply. f

Mounted on opposite sides of this form, -and at a.' suitable or predetermined distance from the base 5, is my fabric-'holding device 7, cilch of these being, preferably and as shown, of less width than that of the form l in order that t-he oppositely-dsposed devices vshallnot entirely encompass the form.f The longitudinal dimensions of each device are dictated by the amount of fabric-el'igaging surface which is to be presented to the hosiery, this being, in a large measure, dependent upon the` character of the goods being treated. Some fabnics have a greater tend` ency to shrink while drying than others, and the amount of moisture in the fabric varies in different mills, since some manufacturers find it desirable or preferable to extract less moisture, (by the whizzer) than others. On the other hand,y some hosiery fabrics-such, for instance, as `Woolen 85 goodshold their moisture in greater quan? tity than others.

The preferred type of device is shown, as ya complete embodiment-,in Figs. 1 to 6 and 9, and usually-includes three instrumentalities, respectively, 8, 9 and 10, in connection with a binder by which the device is secured to the form 1. One ofthesejdevices is what I shall herein refer to as abase or formattaching member 8, the dimensionsd of 95 which are greater, both as to Width and length, than the other two. This base-member is provided, adjacent its end, with two elongated slits or slots 11, of suitable length. The member is preferably a sheet of fire and damp-proof asbestos paper which has been treated on one'side only with a suitable siz'- ing or similar substance, this sizing being, for instance, of a liquid or pasty flour com-V position. f

The second (9) of these three instrumentalities, aforementioned, is a piece or strip of fabric composed of a base or body portion 12 and a pile 18 which, in the present instance, is of a character lto smooth down flat when rubbed in one direction but which when rubbed in the other direction, tends tti stifen, stand out, and offer more or less rethe hosiery drying form tends to dry and\125 shape` the article, my improvedv hosieryholding device eiiciently retains it in' its" stretched condition until the fabric of the hosiery is set and given a fixed condition.

This fabric instrumentality 9 is of less 13.0v

width than the member 8, as shown, and has its opposite ends extended through the slits or slots 11 and disposed against the underside of the member 8 so as to underlie the same. Only the side of the fabric which faces the member 8 is preferably treated to the sizing-compound, already referred to. `If desired, the portions of the fabric which underlie the ends of the member` 8 ay be trimmed or reduced in thickness, as by removing the pile from the Fportions 'of the member 9 which underlie the member 8.

Interposed between the members or instrumentalities 8 and 9, is the backing or fabric-distending member 10. Preferably, this member is of approximately the saine wid-th as the fabric member 9, and of a length approximating the distance between the two slits or slots" 11 in the member 8. This member tends to distendor raise the fabric-member 9 into a plane above that of Vthe outer surface of the member 8. Hence, as shown in Figs. 2, 4 and 5, for instance, the fabric member 9 occupies a plane considerably removed from that of the member 8 and is thus caused to perform its fabric gripping and holding action in a more eiicient manner; the member 8 being, then, out of interfering position with the hosiery as it is being boarded. The member 84's preferably of the asbestos-paper type described With reference to the member 8; but it is preferably sized 0n both sides so that its sized surfaces will be presented both to the sized surface of the base-portion 12 of the member. 9 and alsol to the sized surface ofthe paper-member 8.

These .three components or instrumentalif ties 8, 9 and 10, are bound together-,to constitute an, article of commerce-by a cementitious substance Jsuitable for the purpose. The object of sizing one (the inner) surface of the fabric-member `9, both surfacesof the p-aper-member 10, :and one (the outer) surface of the paper-member 8 is in order that the cementitious binder may more effectively cement these three instrumentalities together; it 'having been found in my experiments that the sizing on the contacting surfaces of the instrumentalities tenlds to present a facing -to the cementitious mass which will, by mer with this mass, effeet a desirable ad esion and prevent the cementitious substance from penetrating into the body of the members. In connection with the fabric-member 9, for instance, it has been found that if the binderinclud- -in-g silicate of soda-penetrates into the body of thefabric, it tends to destroy or disintegrate the threads thereof and, thus, seriously injures it. The sizing revents this and yet permits the fabric-mem' er to be securely cemented to the paper-member 10.

rThis binder may be in the Iform of liquid l glass, that is, sillcate of soda, since this may be conveniently and' quickly applied and dries very rapidly and especially in the presence of heat.- Moreover, liquid-glass, when hardened, constitutes an excellent heat-conductor. 'I have discovered, however, a somewhat different ceinentitiolus mass, one which includesy flour rendered into proper consistency and Icombined with a suitable proportion of silicate'of soda-and with other substances, preferably, toprevent souring or deterioration of the cement-also constitutes an efficient binder.. For my purpose, therefore, it will be understood that I prefer rto use. either a binder comprising liquid-glass in the commercial form, or one which includes silicate of soda combined with other substances.

I prefer to aggroup the members 8, 9 and 10 so as to form the complete device, as an article of manufacture; this including the fabric-member 9 with its ends extended through the slits 11 so they may underlie the opposite ends of the paper-member 8, and with the "paper-member 10 interposed loetween this paper-member 8 and the fabric- 90 member 9. The overlying ends 14 of thef paper-member 8 protect the underlying ends 15 of the fabric-'member 9. Thus, the opposite ends of the fabric-member are not at all exposed to wear, with the result that when 95 the hosiery is being boarded on `the form 1, there is no danger of the fabric-member being injured when the hosiery is stretched Iown over the form, nor when it is being, stripped therefrom.

It is to be understood that one of these articles of manufacture, constituting my structure 7 is preferably to be secured to each side of a form by a binder 16, which may be and preferably is the aforementioned 105 cementitiofus mass used to cement the three members together.I In other Words, when the device is to be appliedl to a form, the rear lside of the device is coated or paintedf with thebin-der 16, and this involves lan ap- 110 plication of the binder to the rear side of fthe paper-member 8 and also to the exp'osed surfaces of the underlying portions 15 of the fabric-member 9. Thus, practically the entire rear surface 0f the form-adherlng mem- 115 ber 8 is secured to the side of the form; and, likewise, the portions 15 of the fabric-member are cemented to the form. In "consequence, the fabric-member is directly cep mentedto the form at its ends 15 and is ad- 120 ditionally secured thereto `byrmeans of the ends of the paper-member 8. x

As shown in Figs. 4 and 5 particularly, the binder may be worked up against the edges of the ends of the paper-member 8 so 125v AYingy being engaged by the edge of the menri tion 18 ofthe paper-member 8 which is inlfrom by the member' 10 as in the termediate of the slits 11 separates the main portion lofthe fabric-member 9 fromv the form, vthis fabric-member does not havethe cementitious binder-which is used to secure the device to the form-applied to its effective hosiery-engaging portion, this being prevented by the portion 18 of the papermember 8. Thus, the member 8 subserves dual functions, namely, to hold in part the fabric-member to the form and, also, in part to separate the fabric-member--at its effec-V tive, fabric-engaging portionfrom the form. On the other hand, the backing-member 10 separates this effective, fabric-engaging portionof the member 9 from the main portion 18 of the member 8, and also presses the effective, fabric-engaging -portion of the member9 outwardly beyond the plane of the paper-member 8. I wish to be understood, however, that the member 10 may, in some instance, be omitted if desired, in which instance the lnain portion of the fabric-memberwould lie agalnst the body-portion of the member 8, instead of being separated therepreferred type of the device.

If it be found that this device, as thus constituted, tends to` retard the drying operation of the hosiery form, one or all of the three components 8, 9 andpl() may be provided with perforations 19, ?2O and 2l, respectively, through which the heat may penetrate, These'perforations may be variously arranged, be of any required form, and be in staggered or registeringrelation. Examples of these are shown in Figs. 11 to 16.

From the foregoing, it will be manifest.

that I have thus provided an effective and durable fabric-holding device which isconveniently and quickly-applied to a f0rm` preferably while heated-and one .which has the effective portion of the fabric-com'- ponent separated 'from the form itself, though havingits unexposed ends -secured thereto; the aforementioned fabric-engaging portion of the component 9 )occupying a plane beyond that of the projecting ends 14 of the member'8 and in a position to per-r form'its designed function of gripping the hosiery and holding it in stretched condition .until it is set, after which the hosiery,

, beingthen dried-.may readily be stripped from the form. Hosiery treated on a'form to which my devices are applied has, in practice, been found to have an improved finish, this resulting (in part) from the fact that the device effectively-holds the hosiery'in intimate contact with the form during the time that the fabric is evaporating its moisture and while being set in the stretched` eondition'intd which it has been brought by holding' structure securable to a hosiery dry- @of holding-fabric having a body-portion eX- the operator.- The hosiery thus finishes at a uniform length, because it'is efectually precluded from creeping orshrinking longitudinally while drying.
