et-ECIFXUATIUN forming part of Letters Patent No. 783,628, dated February 28, 1905.

Application filed February Il, 1903. Serial No. 141,'79`1.

' To all whom t may concern:

Fe it known that ll, Herner J. Geist/ian, a citizen of the llnited States, and a resident of Flew York city., borough of Manhattan, Flew Forli, have invented certain new and useful improvements in 1Woven Flastic Fabrics, of which the following is a. specihcation.

. 'lfhe object of my invention is topi-Ovide a i fabric adapted to cling or adhere to acontigir ous surface to retard slipping thereover; and` to this end the invention comprises-the novel details of improvement that willbeinore fully hereinafter set forth and then pointed out in the claims.

Reference is to behad to the accompanying drawings., forming part liereof,.wl1ere1n- Y Figure l. is a face viewfof a piece ,of fabric embodying my invention. Fig; Q is an ciragln the drawings the numeral l indicates generally my improved fabric, comprising strands of threads interwoven with elastic strips or warps 2 in such manner that portions of the latter will be on one side of a line passing centrally across the fabric, and pi'eferably such portions of the elasticwarps will be ex* posed on the surface of the fabric. rlhe elastic strips or warps 2 are shown extending par allel with the fibrous or ,cotton Vwarps 3, and in producing the exposed portions of the elastic or rubber strips in the fabric l have illustrated'a certain number or series of the weftthreads at t, crossing over portions of certain rubber strips and beneath other rubber stri ps,

a' and another series of weft-threads at t, cross- M ing under certain of the Fret-mentioned rubbeistrips and over certain of the second-inentioned rubber strips, and so ony` alternately f throughout 'the various series of weft-threads, thereby producing interspersed rubber warp portions E2, eirposed on one surface of the fabric, andl such eaposed warp portions are at one side of the fabric, and thus have-ia tendency 4over the cotton warps, as shown.

to curl the fabric like a spring. lhc projecting portions 2 of the rubber strips or bands 2 being interspersed upon the surface of the fabricpresent a gripping or friction medium superior to that produced by fibrous threads alone where rubber strips are wholly embedded beneath the surface of the threads or strands in well-l nown elastic fabrics.

-ln Fig. 5 is illustrated a manner of weav ing the fabric to produce the results described,

la short and narrow portion of the fabric being u2 and il, under rubber Q", and over 2f, and

thence in the return said weft passes around and under the outer rubber warp 2f and under.

28, d., 2, and 2", passingfrom a under and lnthis illustrative form of my inover the cotton warps 3, asshown. The weft is similarly woven for a certain number of picks--say ten, (1n serles of live palrs of piclrs)-erposingfor a certaln length at Q part of the rubber warp 2e, so that such part is uncontined. rlhe neat similar series of picks-say ten-alternate in their passage with respect to warps Qcand 2ethat is to say., the weft passes under rubber warp 2 and over and under f2, exposing at 2 part of warp QIbut out of line transversely with the exposed part of 93., the weft passing under and ln Fig. 2 thirteen rubber warps are shown, while in Fig. 5 but tive such warps are shown for purposes of illustration. rlllie weft-threads pass around the rubber warps at the edges of the fabric, and each second rubber warp has certain portions exposed, and the intermediate rubber warps are all interwoven with the weft. ln the example illustrated a certain series of weft-threads pass over three rubber warps andV under the fourth rubber warp, and the neat series of weft-threads pass over three other rubber wai-ps andnnder the corresponding fourth rubber,and so on alternately, whereby each second rubber warp has portions er posed, but out of transverse line with the adjacent eaposed rubber` resulting in producing transverse lines of exposed rubber, the adjacent lines alternating in position in the longitudinal direction ofthe fabric. Exposed rubber warps arethus interspersed over the surface of the fabric.

it will be obvious that the particular manner of weaving shown and the relative l0cations of the exposed rubber warps may be altered, as more or lessof the rubber warps l0 may be exposed and the alternating arrangement of the exposed portions 2a may be changed. in Figs. l and 2'ibrous warps have been omitted for the purpose of illustration, it being understood that the number of fibrous l'5 warps may be 'varied to suit requirements. The elastic warps atthe selvage are not shown as exposed, the weft binding them in.y it will be observed that certain portions of the weft pass under all the rubber warps, whereby the 2O rubber warps are concealed when the warp is beaten upon the side opposite the exposed portions Qa, as in Eigs and 3. ,t With the elastic fabric above described'it will be apparent that as the exposed rubber portions or projections come in Contact with a surface against whichthey are presented the rubber will have a tendency to cause thev elastic fabric to cling or adhere thereto more or less by frictionalcontact. Furthermore,

as the rubber strips or bands are offsetmore or less from the transverse central line of the fabric they have a tendency to cause the fabric to bend or curl in ther nature of a spring,'or,

in other words, the fabric tends to bendl in the 3S direction toward which the exposed rubber projects. j

A My improved elastic4 fabric will be found useful in various relations, such, for instance,

as in hose-supporters, garters, Suspenders,

40 and the like. In Fig. 3 l have shown the fabric applied in a hose-supporter, and thereby when the fabric is fastened around a leg thev exposed rubber at 2 and the spring-like action will tend to prevent the supporter from slipping down the leg. In Fig. 4 the elastic fabric is shown applied in the form of a garter and with the like effect of keeping it from slipping on the leg, and if used as an armletf it will similarly tend to keep in place upon the arm; When the' fabric is used in Suspenders, the exposed rubber warps and the vspring-like actionwill tend to maintain thesuspenders in proper position upon the shoulders of the wearer.

The manner of placing the rubber strips in the fabric, so as to producethe projecting or exposed portins, and the relative positions and number of the latter, aswell as the crossr section or shape of the warps and other de- 00 tails, may be altered Without departing from the spirit of my invention.

Having now ,described my invention, what claim is-v- As a new article of manufacture, a woven fabric having lines of exposed rubber surfaces "reacts interspersed onO the face of the fabric, the exposed rubber surfaces of one line alternating with the exposedrubber surfaces of anther line, substantially as described.

2. As a new article of manufacture, a woven elastic fabric having lines of interspersed rubber surfaces projecting beyond the surface of 'fibrous threadsof the fabric, lthe exposed rubber surfaces of one line alternating with the exposed-rubber surfaces of another line, substantially as described.

3. As a new article of manufacture, a woven elastic fabric having elastic warps extending longitudinally of the fabric and intermeshing with the fibrous weft of the fabric that extends substantially perpendicularly to the elastic warps, said weft passing under and over certain of said warps producing'exposed and concealed portions of said elastic warps, substantially as described.

a. As a new articlecf manufacture, a woven elastic fabric having parallel rubber warps intermeshing with certain weft-threads, series of weft-threads also passing under and over certain rubber warps to produce exposed and concealed portions thereof, substantially as described. l

5. As anew article of manufacture, a woven elastic fabric having parallel rubber warps intermeshing with the weft-threads of the fabric, one series of weft-threads passing under and over certain rubber warps and an adjacent series of lweft-threads passing over and under the corresponding rubber warps providing exposed and concealed portions of said warps, interspersed exposed portions of said rubber warps being thus presen ted outwardly on the face ofthe fabric, substantiaily as described.' 6.`A Asa new article of manufacture, a woven elastic fabric having rubber warps, portions of said rubber warps being alternately exposed and concealed on one face in the direc- .tio'n of theirc length by the weft, said rubber warps being concealed by theweft ou the oppositeface, substantially as described.

7. A' woven elastic fabric comprising longitudinally-disposed elastic and fibrous warps and fibrous weft, the weft passing under and over the fibrous warps and under portions of the elasticwarps ex posingsuch portions of the latter on one face of the fabric, substantially as described.

8. A woven elastic fabric comprising longitudinally-disposed elasticand fibrous warps and fibrous weft, the weft passing under and over the fibrous warp and under portions of the elastic warps in the same line and under and over intermediate elastic warps, exposing portions of thel 'elastic warps, substantially as described.
