ment between the two layers of each -double Aend of the receptacle; Figs. 16 and 17 are views in horizontal sectionshowin another way of producin a-woven receptac e and its integral end reinforcements, and Figs. 18 and 19 are views in vertical section showin a woi-'enreceptucle similarly produced wit bottom reinforcement. i
Referring first to Figs. l, 2 and 3. the seamless wbven pouch or bag-like body of the receptacle shown in such figures is squared or'rectangularin cross-section. lt
comprises;v a front side or face a, a rear-side or back opposite ends c, c, and a bottom d. A cocer or ap is shown ate woven in connection with the rear side b. Ball and socket fastenings of ordinary type are shown at ,`gf, Fig. 1, applied to the front side a and the cover or Hap e, to serve in securing the latter in place when closed down over the open top or mouth of the receptacle.
rThe ends 0,' c, are constituted by the squared seamless closed end-portions of' the pouch or bag. The lbottom d is constituted bv the squared-seamless closed bottom-portion of said pouch or bag. At h, Figs. 1 and 3, are reinforcing and end-s Haring thicknesses in connection with the said ends c, c.' and at z', Fig. 2.' is a reinforcing and bottom-squaring thickness in connection with the said bottom d. The said reinforcing and squaring thicknesses space the sides 'of the receptacle apart and give the receptacle a rectangular shape in k,cross-section.
A receptacle emhodvmg the features shown in Figs. l, 2 and thereiiore is preferable as regards appearances'. and for other reasons. to a receptacle having ends and a bottom which normally collapse, and which bulge or sag under the pressure or weight of the cona tents of the receptacle. The said receptncle is especially adanted to receive and neatly andsnnglv ht and cover a rectangular pack.- age which inst nils it. l
l have shown three diiierent wavs oi carryirg outy my invention, in each of which 'l produce bv weaving a continuous web or fabric connirls'na7 e succession ci? receptaclelengths, and which continuous web 'or fabric i out or divide transversely into senarate blanks.. each sliitahle for the production or areeentaele. ln the tiret ot such ways, illustrated in Figs. fito 9, the continuons web or fabric is woven with the openings or Inouths of successive pouches or bags` facing one edge ofthe web or fabric, and the closed bottoms thereof facing the otherl edge, and with the lines on which the ends of the pouches orv bags are closed extending transversely of the web or fabric; The web' or fabric of Figs: 5 to' 9 ,is woven in three plies,vnamely ai', t', and e', one above another. The ply a' is for the face or' bag, 'the ply b for the back or rear side thereof, and the ply e for the coyer orflap, r1 '.he plies a", b.,.aire Woven together length- Wise of the web er' fabric along the :line (i2, Figs'. 5 and 7, adjacent one'edge of the web 6r fabric,- .to forrn the closed bottoni of, a pouch or bag. They" are unconnected a't the opposite edge of the .webj og fabric, to form he opening dr Ih'utli of t je' pouch or bag. They are woven togetherltransversely of the web on the lines as, Fig. 6, to close the ends of 'the pouch or bag'. The cover or flap ply e is connected in the weaving with the ply bi at the mouth ofthe pouch or bag, as. shown at the left in Fig. 7, frein one line of closing as to the other. To provide for the end reinforcements It, la, Figs. 1, 3, and 4, the p'lies, a, t', are weven in the form 'f cntinuations' k', It', Figs,l 5l and 6, beyon" t :e line's of closing as, the said continuations' being' utilized presently will be explained.; Toprvide for the bottom reinforcement z', Fig. 2, the plies a', bj', are extended la'terall, beyond he line' of union a2 in the forni o two longitudinal strips i? 2, Figs. and 7, corre sponding if; iengul a) the distante between the two transverse c osing lines af as. The said strips are ailizd as presen ly will be. explained.
n weavingv the' web of igsg to 9 in a sin le-shuttle" loom, the warp-threads and we@ or llin4 may be in erwoven' e in Fig'. 7, tlir'ou hija the length of a' pone or ha interme iate the lines d, a3, 6, onwhic tfe' sides of the puch or bag are united to close the' ends' oftI e' pouch or bag. In Fig. the weftl or filling' is shown as passing freni left to right through the ply ya tothe point a2,- then passing up to t 'e Aply 6; and gagging t0- hg iight 1n tteupper rip 2,- hen passing ror'n right to left back throu h aid stri', and through the ply tothe gft-hand) edge of the'l web; then passing from left to right through p' y e; then returning from v right to left h'rugh said ly then back le to right hrou h ply t' point as, and then inthe same irection thro h lower stri if; then' from right td left ack throu n the said lower stri i and the ply a' to t -e left-tad edgeof he web, to a point adjacent gli@ starting point, thereby finishing me forma in rthe: weavin T he ed'ej of faire' ply'off sa at the'niouth' o opening o' the pouch or bag' front of e'a'ch pouch or through ply, '1f' le', as s own in 9, to form that portion is a selvage edge, and so is the free or righthand edge of the cover or flap ply e.
In closing the ends of the pouch or bag at a3, a3, Fig. 6, warp-threads are merely crossed from ply a to ply b", vand vice `versa, as shown' in Fig. 6. y
In Weaving the portion of web containing .extensions la', t, the weft or filling is inter- Woven with vthe Warp-threads as in Fig. 8. Starting, for instance, at point 2 at the efthand'edge of the web in Fig. 8, the weft or filling extends from left to right through the ply a to the point a2; then passing from ply zto ply 5, it extends from right to left thrg'h ply b to the left-hand edge of the web; then, it returns from left to' right to point a2; then. passing from ply bto ply a', it extends through ply a" from right to, left, to a point adjacent the starting point. In order to weave the cover or flap ply e with practically perfect selvages at both edges thereof in this portion of the web or fabric, using only a single shuttle for all three plies, theweft or filling is passed from ply to ply e at the right-hand side of the' 90 web', as at e2', Figs 5 and 8, atv intervals in the weaving of vply b', and extends back and forthv Within ply efor four or more picks, inter-Weaving with the warp-threads of such ply to forr'n the latter, and thenreturning to ply b after, say, the fourth pick, and interweaying againwith the warp-threads of therespective plies 6 and a" a nuinber of picks before again returning to ply e. The result of this is indicated in Fig. 5, in which the connecting portions of weft or filling alternate in the selvage of ply e with porions of such selvage' which are bound by return-bends of Ithe weft or filling ,'woven this portion'of the web the we' or filling does not interw'ea've with the warp-threads pertaining to the longitudinal Strips '52, 2, and such Warp-threads Simply o'at, as indicated by the dots at the right hand side' in Fig. 8. Beyon the continuations k', k', of the plies a', b", the weft vor filling is interwoven `'with the' Warp-threads of the cover or fiapply of the same exten ngbetween one pouch o'r 115 bag and the next the web or fabric. Ply e' 1s con inu'ou's, as shown in Fig. 5', and the portion of the sarneintermediate one pouch or ag and' the next is suflicient to provide forthe turning back and under of the raw or cut ends of the cover or flap against the main portion of the latter, as hereinafter exn plained, in finishing the cover or iap. Betweenthe continuations la', z, of plies a Z a'.t the end of one 'pouch-length or bagleng'lthand the' corresponding continuations at t je lbgiufiiig of the next length the warpthread o f theI plies a, bf, preferably vfloat -Wit out bein i interwoven with weft, as ehown in Figs.f 5 an' 9, to expedite the operation of 130 the receptacle.
' each of a length suitable weaving, and avoid useless expenditure of wett or filling, inasmuch as such extensions are not required to have a length as great as the projecting end-portions or' the cover or dap. Between the end of the longitudinal strips 2, 2, of one receptacle-length and the beginning of the corresponding strips of the next receptacle-length, the 'warps of such strips similarly float Without being interwoven with weft, as in Figs. 5, 8 'and 9.
'llhe web woven as represented in'Fig. 5, and containing any required number ot' receptacle-lengths is divided up into blanks, for a receptacle, cutting across the ply e and the floated ther other two plies, on the transverse lines 9, 9, Fig. 5, intermediate successive pouches or bags. A length or blank thus separated from the web is' represented in longitudinal section in Fig. 6. ln such blank the cover or dsp is integrally joined to the top edge of the back or rear side of the receptacle from one line of union or closing a? tothe other, and end-portions thereof project beyond the closed ends of rlhese projecting end-portions are selvaged at both the upper and lower edges thereof. rl`he short looseportions e2, e2, of weft or filling which connect the lower edges of such projecting end-portions to the lower portions of the extensions k', h', are cut in order to free the lower edges of the cover or flap, and are then trimmed away. rjlhe said end-portions then are folded back upon the adjoining portions of the cover or Hap, the raw or cut edges are turned under, and the folded-back portions are stitched in place as shown in Figs. l and ll. Each end of the receptacle is nished by turning the extensions il', h, at such end back in opposite directions against the adjoining portions of the side-plies, and
by warp-threads of "securing them to such portions by vertical and transverse lines of stitches h2, h, ha, il,
^ lFigs. l and d. Ilhe bottom is finished-by turning the strips i2, 132, back in opposite directions a ainst the adjoining portions of the side-p ies, and securing them to such portions by lines of stitches is, z'a, extending lengthwise of the receptacle. and also across the bottom near the ends of the receptacle. :The lower corners are inished by transverse vlines ot stitches ic, la, through the corner portions ot the pouch or bag and the rojecting end-portions of the extensions 7a fr', and strips i2, 2". The receptacle is then in the shape'and condition represented in lli'ig.
,with the portions thus fastened togetherat the said corners projecting as shown. llt is turned inside out, and-the result is shown in Fig. l. The bottom reinforce e', consti- -tuted by the longitudinal strips. i2, 2, dass the length ot the recencle. and gives shape to the receptacle at the bo r .ma of the latter @Emi formats bh@ thereof at the bottom, by squaring the bot-1 tom and holding the sides apart at the'bottom. The corner-projections lo', la', now turned inwardl as in Fig. 2 contribute to keeping the wi th of the bottom and maintaining the shape of the lower corners. IThe end-reinforces k, it, constituted by the vera tical end-extensions h', h', give shape to the receptacle at the ends of the latter, and x the depth ot the receptacle, and its interna] diameter at the ends, by squaring the saidv ends and holding the sides apart at the ends. lin consequence of the end-portions of the iiap or cover being joined to the ends of the receptacle and extending half-way forward from the back, the top. of the receptacle thereby is more eil'ectually closed, and its contents better protected, when the cover or flap is turned down and secured in place. The fastenings f, g, ma be applied either before or after turning t e receptacle inside out.
Fig. 10 shows a receptacle modified in re spect of the end-portions c, e, of the cover or tlap e". ln this modification the said end# portions do not extend partway forward upon the ends of the receptacle, as in Figs. 1 and 4, but project in line with the rear side, with the extremities of such end-portions simply folded back, their cut edges turned under, and' stitched in place. The cover orap is longer than 'the receptacle, so that said end-portions project bevond the ends of the receptacle, to more eiiectually close theopening and protect the contents. ln weaving the receptacle of Fig. 1U, l weave the'cover er Hap ply joined continuously to the 'rear' side of the receptacle only tor a `distance corresponding with the length of the. finished receptacle, namely ply in weaving portions thereof in alterE nation with portions inthe other two plies,
Elib
as already explained `with reference to Figs. l
vlin the second wav oil .fw ing out 'my invention, illustrated in Figs. 1l and l2, the.. continuous web or 'fabric is woven with the `openings or mouths of successive 'pouches' ror bags extending transversely ot saidweb or fabric.; and the elo bottoms also' en tendinel transversely thereof, with the lines on which the ends oit the pouches or bags are closed extending longitudinally' ot the web or fabric. e web or tabricf of Figs. Ilil and l2 is woven in twdplies, one-ave the other. At' ity?, Fig. il, the two plies constitute the freintog' porno 'for the reo bottom of a receptacle. Succeedingthe pro- -fduction of such portions, vthe two plies are woven together atp to form the line of closing Aor union for the bottom of the receptacle. lNext the two plies are woven of sufficient extent to constitute the two sides a, b5, of the pouch or bag of the receptacle, such plies being joined together inthe weaving, along thelines a, a", to close the ends of the said pouch or bag, and being continued laterally beyond such lines at the opposite margins of the web or fabric to form the opposite pairs of end-reinforcing strips h5, if. The succeeding portions of the web or fabric are flap-portion Ac5, followed by the bottom-reinforcing portions 4, 4, for the 4next pouch or bag, and so on. The bottom -reinforcing portions 4, 4, may be woven as two plies which arev entirely unconnected with4 each other at one margin of the web or fabric, and practically unconnected at the other margin, they being merely connected at "intervals by portions of weft or filling e2 extending from one to the other, as described with reference to Figs. 5 and 8. That is to, say, the web or fabric being produced with one shuttle, I first weave a number of picks in one of the plies, say four, without weaving in the other ply; I then weave a corresponding number of picks in the latter ply, without weaving in the first ply; I then Weave said number of picks in the first ply again, and so on. The result is that the portions 4, 4, are produced with perfect selvages at one margin of the web or fabric, and although they are joined together Vby the connecting portions e2 of weft or filling at intervals at the other margin, yet when such portions of weft or lling are cut-and trimmed the selvages. at such margin are practically as firm and perfect, andl are entirely satisfactory. The dine a4 of closing or joining the sides of the pouch produced merely by crossing the warpthreads, as at the lines a3, a3, in Fig. 6.
The main portion of the' pouch or bag may be woven as in Fig. 12, in which, starting at the point 3 at the left-hand margin of the web orv fabric the weft or 'filling extends toward the end-reinforcing strip 'for the width of the said reinforcing strip. At the pointfl, corresponding with one closed end of the pouch or bag, it passes up into the ply a5, and continues to the right in the latter to the point 5, corresponding with the other closed end passes down,-
of the pouch or bag, where it and continues to the right through the lower end-reinforcing strip h5 at the right-hand margin of the web or fabric. It then returns from right to left through the said reinforcing strip and the lower ply b5 to Athe point 4 at the left-hand end or bag, where it vpassesinto the upper ply lpasses down to the lower at the right-hand side, right-hand margin.

I have shown the cover or Hap e5 produced by weaving in the upper ply alone in continuation of the back sideJ of the pouch or bag, until a suiicient length of single-ply fabric for the purposes of a cover or Hap has been produced. After said cover or Hap portion has been woven, the two bottom-reinforcing plies 4, 4, for the next receptacle and so on. In weaving the cover or Hap-portion and the said bottom-reinforcing plies a4, a4, the warpthreads of the end-reinforcing strips h5, h5, fioat as in Fig. 11, and subsequently are trimmed from the ends of said strips.
The web or fabric produced in the manner last described is divided up into receptaclelengths or blanks by cutting across tne two plies 4, 4, adjacent the end of the cover lor A short portion of the under ply 4 is left upon the top edge of the pouch or bag, to be folded back with its raw or cut edge turned in. and stitched in place, as at e7 in Fig. 13, to finish oii' the said edge.
` The receptacle is otherwise finished substanvcontemplate also weaving the cover or flapportions e5 ina flat and extended state, with the warp-threads of the opposite ply floated from the top edge of the front side of the pouch or bag to the beginning of the corresponding bottom-reinforcing portion 4 for the next pouch or bag. i
Double bottoms and double-end-walls such as shown in Figs. 2 and 3 may be further reinforced if desired, in accordance with one feature of the invention, by inserting between the bottom d and the two bottomreinforcing plies 2'., lengths or strips o, o, Fig. 14:, of reinforcing material of metal, vegetable fiber, etc., lengths or strips p, p, Fig. 15, between the end-reinforcing plies la, and theendwalls c, c. l
Figs. 16 and 17 show -a diferent'way of producing 'the woven receptacle and itsl inof-the pouch te gral end-reinforcements. The receptacle right through the said" and by inserting similar -es iswoven aceordingto well-y Returning from right i iin p maant -fabric with the plies unconnected along one margin to form the open mouth of the receptacle, and joined together lengthwise of the receptacle to close the bottom of the latter, the said plies being interwoven at intervals to close the ends of the receptacle. The requisite fullness of the receptacle is provided for by well-known procedure. Beyond the closed ends the Weaving is continued to form end-reinforcing portions, such portions intervening between one pocket or pouch and the next inv the web as produced in the loom, and being cut throughy transverselyin severing one receptacleblank from the. rest. The result is vthat as shown in Fig. 16 the'receptacle is woven with the end-extensions k", ha, in line with or continuation of the back-Wall b", and in this instance of greater thickness than said back-wall as a result of interweaving therein Ithe warp-threads of the front-wall a8 and ends o8, c", in addition to those of the back# wall. In finishing the receptacle the said end-extensions are folded around against the endscs, cs, as indicated in dotted lines in ig. 16, and secured to the said ends by stitc es h1", hw. After the bag has been turned inside out, the result is as shown in Fig. 17. The additional reinforcement of Fig. 15 may be added to the construction shown in Figs. 16 and 17, as will be Figs. 18 and 19 show a bottom-reinforcement produced in manner similar to that in which the end-reinforcements of Figs. 16 and 17 are-produced, namely, by weaving the receptacle with a bottom-extensionin line with continuation of one of the walls in this instance the back wall b, and o eater thickness than said back wall. 1n nishing the receptacle the said bottom-extension is folded around against the bottom of the receptacle, as indicated in dotted lines in Fig.. 18, and seciired to the said bottom by stitches lin. Fig. 19. hows the result after turning the receptacle inside out. The additional .reinforcement of Fig. 14: may be added to the construction shown in Figs. 18 and 19.
