Beit 'known that EDWARD C.'v WARD, cit'- ley Falls, in the county of Rensselaer and State of New York, has. invented certainV new and useful Improvements in Knitted .Fabi-ics, of which the following is a speci'A ication.

This invention relates to knitted fabrice, .and has for one of. its objects the provisions 'of knit .goodshavingclosely lknitted and..

contiguous openly knitted portions arranged alternately throughout the 'width .of 'the' .fabric and having each ,of saidportions continuous throughout the length of .the

, piece of goods.

A further object of this invention is the provision of knit goods 'ci .the kind above'` describedwlierein the openly knitted portion'jis equally. spaced with close 'knitted ribbed portions. More vparticularly this invention hastorv its object the provision of a knitted4 goods whereby -a closely i knitted :portion coinfmonlyv` knownas taii'eta stitching and an openly knitted portionequallyspacedwith i lribs thereingkuown :as rib stitching forma fabric possessing durability and being."

neat'in design and pleasing in appearance.

A 'still further .object of this invention is the'provis'ion of a `knitted fabric of good appearance capable of being economically manufactured in which the design may be varied as desired widthwise of the piece of goods.v

Other objects of this invention wlll 1n part be lobvious and 4inl part hereinafter.l pointed out'.

Certain -features'herein shown and. described are shown, described, and 'claimed -clai'ity.

- In the practical embodiment 'of my ini vventioinlproduce the 4fabric 1 1 comprising .a series oi closely knitted 'portions 10 com'- m'only known as taHeta stitching combined wlth the openly knitted *portion 12,* saidv openly .knitted portions bein equally spacedvand divided as at le- 14' y ribs' 13 13.- The-closely knitted portion and the openly knitted portion spaced-as shown 'in Fig.l

.fabric Said portions l() are. formed .by threading the warp and thread guides 15 with*` threads as i6, said guidesV being carried-by the usual guide bars, while warp two closelyknitted portions 10 with a loosely' knitted portion l2. in lbetween having ribs 1 3 formed thereon' in a manner to be here -inafterdescribed.-'ihe'wicltli of the fabric is from left to right, while. the'le'ngth of@ the piece is. measured vertically from' the tions' 10 and. 12 preferably run continuously' throughout thelength.A It will be underin my zzo-pending application for patent stood, however, :that any number o alter` Serial No, 501 Patent Oice. .0.

The invention accordinglyI consists 1n the ,284 tiled in the United States features of construction, combinations `ozt elements and arrangement of parts which will be exemplified in the construction hereinafter described` and of which-the sco e' of application will be indicat'edin the.

.improved labrite., uw, thicknesses' 'of the.

nately arranged closely 'knitted portions or.

taifeta stitching-and loosely' knitted portions having ribs thereon may beproduced I in the width of the fabric by provldin the 10o desired number of needles widthwise. u rthermore, the' spacing d the closely knitted l and loosely knitted portion may also be varied by varying the number of needles' and guide provided for each of these por- 105 tions while the widths .of the ribs and the widths oi the loosely knitted portion between two adjacent ribs may likewise be.

varied as will hereinaiter become evident.

being exaggerated for the sakel of` '1 alternate contiguously widthwise of the '80 threads as l-18- arecarried by their corre'.

.upper to the lower edge, so that 'said' pori The fabric will. be described @DBQCQQ' UQ with the simple chain stitch but any other desired stitchv may be employed.

Referring lto Figs. 2 and 3 of the drawing, the warp thread 16 carried by the guides 15 engage the needle 19 forming the loop 20. The guides 15 thendirect the travel o't' thread-16 to the right adjacent "needle as shown 'at 21 for engagement therewith toform the loop 22'and then thread- 16'travels backv to the left as `at 23 and engages the adjacent needle 19 and again commences this cycle of motion forming'the loop 24. beneath the loop 20, etc. All the threads of the guide 15 andthe needles 19 in' t-he width of the closely knitted portion of the knittingma-v chine simultaneously produce this cycle of motion for the 'lengthof the fabric desired.V

The guides 17 operatesimultaneously with the guides 15 and the threads 18 carried byl them interlock the threads 16 to -form the closely knitted tafeta stitched portion 10 of the fabric 11. The thread 18 having the loop 25v formed thereon `from its last engagement with the needle 19 interlocks. the thread 16 as shown at 26 and is directed by its'corresponding guide 17 totravel to lthe right as 27 to the second adjacent `needle for engagement therewith to form the loop 28 and then travels tothe left, as at29 to the second adjacent needle for engagement therewith to At'orm the loop and-continues the cycle of motion operation already described. l The and needles,19`in that 'width of the knitting machine devoted, to the closely knitted or tafeta stitched lortion operate simultaneously, and the gulde bar carrying the guides -17 operates simultaneously with the guide bar carrying the guides4 15.

In Fig. 3 the actual stitch' made by each of the threads is shown` enlarged as well as the interlocking between the threads producing an integral closely knitted portion 10. Fig. 2 diagrammatically indicates the path of motion of the'threads, the full lines referring to the threads 16 and dotted lines referto the threads 18.' l v j or the Sake of brevity, I will confine "my description of the loosely knittedportion -12 to the section 14. andthe rib 13 thereon. This portion 12 of my fabric -11 is formed simultaneously with the closely knitted portions 10 and with the same motion of 'the guides. I obtain my loosely knitted portions by omitting to'thread every other two guides 30, thus the width vof lthe section 14e-14. is equivalent tofthe distance bridged by four consecutive guides. To obtain the loosely knitted; sections 14 of the portion 11, I employ the warp thread 18 threaded in the guide 1 as already described. I do not interlock my thread 18 with the warp thread rin 16v as in my closely knitted portion vl0 but omit it entirely. This is shown in Fig. 3

4where I' vindicate by the letter A; the loosely ides 17, threads 18 carrying these guides. The thread'l guided i by its guide 15 engagesa needle 19- Jforming the loop 32 then is guided to Vthe right asvat33 to the adjacent needle for enga-gement therewith, thus forn'xing the loop 34 and-then o travels to the left as at 35 engagingtlleadjacent needle and forming the loop 36, etc.,

continuing the desired length of the fabric. The thread 31 interlocks with the thread 1S to form the stitching commonly known asl rib stitching. The width of the rib section- 1 3 in the embodiment of my invention illustrated in the drawings is therefore seen to comprise two threads 31 of four strands each and thesingly strandedthread 18 or 9 threads in all. l

The number of these loosely knitted sec,-

tions-14-14 andrib sections 13,'13' that I may enter vinto my alternatingv openly knitted portion may be varied by-various changes in the numberof guides employed.

Furthermore, the design may be changed tol various patterns by omlttmg to thread the Aguides in other series thaneach alternating two, or by assembling more than two threads and guides to make the rib section.

By varying- .the amount ot transverse, movement of the guide bar, by changing number of said guide bars by changing the relative spacing or gauge of the effective needles. various designs other than those illustrated may be made and variously colored threads may be worked into a suitj able design.

. It will thus be seen that there rprovided a method in which theseveral objects of this `invention are achieved and which is well adapted to meet the conditions of practical use. I

As various possible embodiments might be made of the above invention and as various changes might be made in the embodiments above set forth', itis to be understood that vall .matter herein set forth' or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.V

Having` thus describedl my invention, lI

S. Al motor vehicle frame comprising a 'pair of oppositely disposed longitudinal members in the saine horizontal plane except` tudinal and by the lower portions of the latter cross members, and a floor carried by the upper surfaces of theundepressed portions of the longitudinals and of the cross members.
