Patented Dec. 7, 1920.

Application filed September 9, 1916. Serial No. 119,210.

.To all whom it may concern.'

Be it lrnown that l, HOWARD l, Monnis, a citizen of the United cdtates,residing at San Diego, in the county of San Diego and State of California, have invented new and useful linproveiiients in Loom Elements, of which the following is a speciiication.

rlfhis invention relates to looin elements, and more particularly to certain elements Of that loom construction and organization disclosed in another application for U. S. Letters Jijatent for looms, filed by ine September 9, 1916, Serial Number 119,208. ln said identified application the various loom ele ments of the present inventionv are described, disclosed, and claimed in association with other features of the complete looin construction and organization. In the present application claims are to be directed at the leoni elements separately or in combination, or suoli thereof as are intimately and iininediately associated and combined and inter-related, and more particularly with relation to what is designated or described in said other identified application as the weftproducing ineens, or means for associating with the partially-formed fabric the weft units or elements. In said other identiiied application a particular object of the invention is set forth as being the L rovision of a loom constructed and Organized with the capability of producing a bias-woven fabric, "f abrio in which the warp and weft thread units are related, warp to weft, at an angularity of approximately 90 degrees, but more particularly are related each to the side edge or edges of the fabric at angles of less than 90 degrees; and said invention of said identiiie application further contemplates the Y; vision of selvage portions or units at the side edges of the bias-woven fabric., and preferably independent' of the warp and weft unit threads, and serving, as long as associated with the warp and weft units, to prevent distortion or lengthwise stretch of the fabric. The present invention is not to be understood as limited to any particular coniplete organization or construction of a loom, or any loom devised for the purpose of turning out any particular or specific pattern or weave or Organization of fabric, whethei bias-woven, provided with a selvage unit Oi units, or Ofwhatever other design or struc-V tural entity. T he present invention relates Ato loom elements for providing and asso-4 ciating weft units with the warp units of a fabric, irrespective of the specific design of the fabric or Jdie inter-relation of the warp and weft units or their relation to the fabric side edges, and irrespective of the finish or structure of the side edge portions of the fabric. T he invention, in addition to these facility in control, and necessitating a Inini.

mum of requirement of care and attention, and of great adaptability to varying conditions and environments of use and service, and which will be generally superior in eficiency and serviceability.

Vlith the above and other objefts in view, the invention consists in the novel and useful provision, formation, construction, combination, association and inter-relation of parts, .members and features, all as hereinafter described, sliown in the drawings and finally pointed out in claims:

the showing in Fig. 6 being with respect to plurality of weft threads in the production p of multiple weft thread units; and Y Fig. 10 is a detail fragmentary side elevation of a portion of the showing in Figs. 8 and 9, upon a slightly reduced scale with re# spect to the scale of said other figures;

Figs. 5,y 6, 7, 8 and 9 are Ylikewise all upon an enlarged scale.

Corresponding parts in allithe figures are designated by the same refe/rence characters.

Referring with particularity'to the drawings, the improved and novel loom elements disclosed therein comprise, in the main, a shuttle-needle` A by which the weft thread or threads a is or are thrown or applied so vas to be resultantly associated with the warp thread units or the partially-completedV vfabric (not shown); weft thread supply means B froi'nvwhich such weft thread or weft threads is or are furi'iished to the shuttle-needle ii.; weft thread guide means b which may be included within the weft B, and wher 'y the weft thread furnished to the shuttle-neerll is definitely determined or controlled as to amount or length for each stroke of the shuttle-needle; temporary i iining 'means C V'whereby the'wef't tn. threads is or are held during the formation of a given single or multiple weft thread unit', .and for such 'time therea er ray be desired in 'accordance w'th the pio @sion and operation -aind inter-relation of al'lthe elements' of a giveuloom includii'ig such retaining means; operating-means D for t andV operating means 'c 'slnittle-needle for Vthe tempor` ry "ociated with the retaining means other mentioned elemen s is a table F over' which the fabric which has received the weft thread units is passed to such further means for taking off or disposing of the fabric or operating upon it as may be provided in anyv particular construction and organization of loom.V This table is shown as having a surface portion f over which the work is passed, which is curved transversely, or

arcuate, to conform to the path of the shuttle- `needle A, which is likewise shown as curved or arcuate and playing in a segmental path.

The temporary retaining means C are disposed adjacent to one end 11 of the table F, namely, the end next adjacent'to the path of play of the shuttle-needle A. The operating means E for the temporary retaining means C preferably include a rotatable shaft 12, from which the table F may be supported Aasby a plurality of spider arms 13 which Varmy 16 oscillatory movement to cause the shuttle-needle it. to execute insertion and withdrawal strokes, whereby the weft thread a is shot into the suitably supplied partially completed fabric to introduce therein and associate therewith the weft thread units. ln Fig. 1 the shuttle-needle A and its carryine arm 16 are shown in full lines in the positions assumed at the end of the insertion stroke, and in dotted lines in the positions assumed at the end of the withdrawal stroke. Y

The tubular shaft 18 revolves upon the concentric shaft 12 by means of a bushing 19 within the tubular sha ft and fast thereto; and the shaft 12 revolves within a ljournal 2O which is supported at the upper end of a standard or pedestal 21. Two properly organized cams 22 and 23 are fixed upon the shaft 12, and operate respectively upon rollers and 25 provided'at the i'nnerends of radial rnds Q6 i .d E27 respectively, which latter with such rollers and cams are included within the operating meansli] for the temporary retaining means C; The rods?? play tl'irongh the or keepers 151 above mentioned. The radial arm 1G is provided at its outer end with a suitable block 2S through an opening in which the shuttleneodle body :29 is passed, a vset screw' or the like 80`being moun ed in the block'to hold the shuttle-needle in pos'i'tion.` The shuttlenoedle body is curved, in the construction shown in the drawings, to conform to a true are, and its rearward or inner end, inward of the block 28, is bent laterally 29 and upwardly and laterally deflected as at 29b to terminate in an open mouth or thread guide 29C, such body 29 being tubular throughout its entire length with the eriception of its outer or forward or leading end portion 29d, which is solid and tapered or rounded to a-point so as to more effectively pass through the shed. of the warpthreads on the insertion stroke. Adjacent to the point or eading end 29d, the tubular shuttleneedle body 29 is provided with a lateral eye or opening 293, which communicates with the interior of the body 29, but only at one side, not being a through opening. As shown in Figs. 8, 9 and l0, a plurality of such eyes or openings 29e may be provided at the forward end of the shuttle-needle body, for accommodation of a plurality of weft threads a 56 and the application thereof to t-he partially-completed fabric in the employment ofthe temporary retaining means C in plural provision. The weft thread o is furnishedto the needle A, as stated by supply means B, which serve to tensionally supply such weft thread, the same comprising a standard 3l rising from a suitable weft thread ball support 32 carrying a weft thread ball or balls 33, provided in number in accordance with whether a single or more weft thread o is or tobe supplied; a

` rocker arm 34 being mounted to oscillate at the upper end of such standard 31, as at 35 intermediate of its ends, one end thereof be? urged downwardly by a contractile coil spring 342s connected therewith, and the otherend thereof vbeing connectediwith an adjustable bracket 35?' surrounding the standard 3l. A transverse arm 36 is connected with the standard 31 immediately below the rocker arm 34, which latter is provided at its end opposite that engaged by the spring 34W, with a thread guide or eye 37, such transverse arm 36 likewise being provided at its outer end with a thread guide 38 for the ball 33 from which thread is to be supplied, or with one suoli guide for each such bobbin, and from'which the thread or threads leads or lead tofthe thread guide or eye 37 at the end of the rocker arm 34e.

From such ,eye 3 7 the thread is led to and enters the thread guide 29C at the inner deflected end ofthe shuttle-needle body, whence the thread is led through the tubular shut` tle-needle body and outwardly through the eye or eyes 29e to he introduced within the partially-,completed fabric and associated temporarily with the temporary retaining means C.

y The weft thread guide means 7o included generally within the weft thread supply means B comprises a curved or segmental or arcuate guide plate ,.38 mounted upon the base 3.9 of the standard 21, and ranging in an arc slightly greater. than and substantially (3o-extensive with the arc of the path of travel of the shuttle-needle body 29, and

. at one side of the same, and having at one side a radial flange 38a. namely, the .edge

reinotefrom the path of travel of the shuttlc-needle body.29. The arrangement of the several Vfeatures is such that the weft thread guide means b is disposed first in order, counting toward the table F, the path of the shuttle-needle body 29 is next iii order, the retaining means C are next in order, and the table F is next in order. lt results in the operation of the shuttle-needle and the supply means B and weft thread guide means Z), that the thread or threads a, is or are directly fed over the curved guide 33, upon the withdrawal stroke of the shuttle-needle A, and more thread is laid upon said guide than is required to supply the shuttle-'needle in the insertion stroke of the shuttle-needle; so that upon the insertion stroke the rocker arm 34, depressed at the end carrying the eye 37 during thel withdrawal stroke of the needle, may rise gradually under the action of the spring 3d, and put the thread a being fed to the shuttleneedle under yielding tension, so as to prevent any distortion of the needle body 29 or prevent any loosening or overlapping or entangling of the thread fed from the eye or eyes 29e of the shuttle-needle. Uf course upon the withdrawal stroke of the shuttle-needle likewise suiicient thread is supplied to and 'through the shuttle-needle for constituting` the respective one-half of the weft thread unit introduced within the Apartially-completed fabric upon suoli withdrawal stroke of the shuttle-needle. Of

course the thread introduced on each stroke wovenfabricto produce a multiple weit thread unit, as indicated in Figs. 8, 9 and l0,

in which case there are an equal plurality of such retaining pins 4:0 so provided in each i stance, in either case such retaining pin or retaining pins being mounted at the outer end of rockerl arm 4:1 fulcrunied as at d2 beneath the table F., so that suoli retaining pins may be swung radially of the table and projected beyond the outer surface or periphery 7L' thereof, by the rods 26 and 27 respectively, of the operating means E of such temporary retaining means` Each rocking arm is pivotally connected as at d2a to the rod 26 or 27, and is jointed outwardly of the respective fulcruin 4t2, as at l1-lf, which fulcruin is between the ends of the rocking arm, to provide an extreme outer end portion i-la which carries the pin or pins 40; and as clearly shown in Fig. 3 .such subdivided or jointed end of each rocker arm 4]. is capable of adjustment as between its parts by means of an adjusting screw 4l" threaded through a projecting portion of one such subdivision of the rocks arm and bearing upon a progectingportion of `the other subdivision thereof, thus deter-` be urderstood that such features are to be provided in the complete loom within which the loom elements of the present invention are incorporated, such provisions being made in the complete loom organization disclosed and described in said other application for U. S. Letters Patent hereinabove identified. rIhe inner end portion of 29h of the shuttle-needle `body 29v is deflected outwardly and laterally as described so that the thread guide 29C may overlie the curved guide 38. rIhe iiange 38a acts to prevent displacement of the thread from the guide 38.

is manifest that many changes and modifications and variations may be made in adapting the invention to various conditions of use and service, and which departure may be made from the specific provision, construction, combination, association and inter-relation of parts, members and features herein shown and described all without departing from the spirit of the invention and a fair interpretation thereof.
