ELASTIC WEBBING.

Specification of Letters Patent.

Patented Dec. 31, 1907.

Application filed May 28, 1907 Serial No. 376,087.

' To all whom it may concern? forms a place of anchorage for the holdingtension appliedto the supporter in use. In use elastic webbing hose supporters weaken and gradually become non-elastic adjacent to their place of attachment because the elastic strands are often cut in sewing the Webbing to the corset. and they also pull through the channels in the fabric and as soon as this condition. obtains the supporter soon becomes useless.

In the manufacture of elastic webbing for hose supporters the webbing is woven under tension at the maximum elastic limit of the webbing, that is, with the elastic strands stretched, the warp threads taut and the weft threads separated, consequently the limit of contraction brings the weft threads together with the warp threads loose but does not return the parts to their normal condition, therefore the elastic strands are gripped in the channels in the Woven threads and cannot return to normal proportions, and the object of my invention, based on this condition, is the production of a Woven section at one end of each strip of the ordinarily wovcnelastic webbing which is to be attached to the corset and in which device the disadvantages inherent in the present elastic webbing shall be overcome. V

In carrying out my invention, it weave the desired amount of the elastic webbing as usual under tension at the maximum elastic limit of the webbing. i then release the tension and weave a predetermined length 'under normal conditions without any tension. Th weaving under tension is performed with the elastic strands at a small cross sectional area. Conse uently when tension is released the elastic %llI( .8.(.lS increase in area, drawing the woven fabric together, but the strands are not up to their maximum; while at the place of weaving under normal conditions and without tension the elastic strands are of normal cross section and the Weaving close together, snugly holding the elastic strands. It is therefore apparent that at the line Where the weaving under tension stops and the normal weaving begins, the increased cross sectional area of the elastic strands will prevent them pulling into the channels of the first aforesaid portion under the tension of use; therefore the useful life of the elastic webbing is increased.

The portion woven under normal conditions and without tension is the part sewed into the corset and it is my intention to leave a part of this Weaving outside of the line. of sewing, hence the sewing oi the elastic webbing to a corset does not injure the elastic strands to which tension. is applied or their anchorage, or impair the function they perform.

In the drawing, Figure 1 length of the elastic Webbing woven accord ing to my invention. Fig. 2 represents by a broken plan a hose supporter of this elastic webbing according to my invention. Fig. 3 is a cross section at ac, 0c, of Fig. 2. Fig. 4: a cross section at y, y, of Fig. 2. Fig. 5 represents by a broken plan a. modified term of my invention and Fig. 6 is an edge view of the webbing shown. in Fig. 5, the part in represents a Fig. 5 shown turned over being straight'in Fig. 6.

I prefer to weave the elastic webbing of my improved hose supporter of a continu ous strip or length in alternate sections; each alternate section a between the parts 2 and 3 being woven as usual under tension and substantially at the elastic limit of the completed webbing; the sections 6 b'etwlines and a and 3 and i being woven under normal conditions upon the entire release of tension, consequently the elastic strands in the section a when tension is released do not return to their normal condition but are gripped by the woven threads'oi the fabric and the weft threads of the weaving are not close together as are the weft threads intween the sections 1) are cut at the center on the line 6 and are to be woven of sullicient length to form the depending portions of two hose supporters.

In the enlarged view, Fig. 2, l. have shown a clamp c, a loop member d, a. plate 6 and stud jwhich are employed as usual to com plots the hose supporter and form a means to contact with and grip the hose.

In Fig. 3, the section at :r, a, is illustrative of the area of the elastic strands woven under tension and Fig. 4 illustrative of the area of the elastic strands woven without tension, or in other words, under normal conditions.

From the foregoing, it will be manifest that when this form ofelastic webbing is employed as a hose supporter and the same is connected to the corset at the end woven under normal conditions, that the elastic strands cannot pull out or from the sections b into the sections a, and that because the elastic strands are thus anchored in the sections b, that there will at all times be the desired elastic character of the webbing unless some of the elastic strands should break which is unlikely in view of the even distribution of the tension. It will also be apparent that said strands cannot as has hcreto'fore been common in elastic webbing, pull through the channels, in other words, that they must remain in position, and further more it will be apparent, that because of the extent oi the enlarged elastic strands that are held in the sections 1) that there is snllicient of said strands gripped by the webbing under normal conditions as to form a. safe, secure and permanent hold or anchorage l'or these strands, so that their useful life will be increased and be given a permanent charactor.

in the form. cl my invention shown in Figs. 5 and 6, the short section of fabric woven normal and without tension instead of being made solid as shown in Figs. l- 't inclusive, and hereinbefore described is made double or in two parts, that is, there are two members as shown in Figs. 5 and. (3, which are arranged parallel, each member being a complete woven material in itself with the elastic strands 0 free between the parts. in

this .lorm of my invention the elastic sections woven under tension arc of solid character and the sections woven under normal conditions without tension are prolongations of the former sections and also of solid character; the elastic strands between the parts of the latter sections are free.

Upon consideration of Eigs. 5 and 6, it will be apparent that the elastic strands where they are free between the parts and of larger area than the same strands combined in the channels of the webbingin the section, that the [rec ends of these strands when the section is under tension cannot because of their increased area pull into the channels of the fabric in this section but are obliged to keep their place, consequently the tension is distributed evenly throughout the length of the said elastic strands in the webbing and there is nothing to injure these strands or to cause them to break with roper use. The useful life of the elastic welibing hose supporter is thus greatly increased; the said improvement increasing the value of the elastic webbing l'or hose supporters for these reasons. Furthermore, the solid fabric portions form a lirin and substantial al'ic-horage material to sew into the corset, which are not injured by any tension that may be applied by the fastening devices of the hose supporter to the webbing.
