LOOM FOR WEAVING CTENILLE.

Specification of Letters Patent.

Patented Oct. 22, 1907.

Application filed January 27, 1906. Serial N0.298,226.

To all whom it may concern:

Be it known that we, Thomas Fox Ns'YLoR' and ARTHUR NAYLOR, both of Green street, Kidderminster, in the county of Worcester, England, carpet manufacturers, have invented certain new and useful Improved Cutting Mechanism for Cutting the Web in a Chenille-Weaving Loom During Weaving, of which the following is a specification.

Our invention relates to an improved cutting mechanism for cutting the web in a chenille weaving loom during the'weaving oi chenille suitable for use in the manufacture of carpets and the like, such chenille consisting of a single thick core around which are looped the wefts or tufts which, when out, constitute the 'pile of the chenille. I

The wefts or tufts are woven together into a flat web and they are firmly held together by four sets oileno or doup threads, two sets on either side of each thick core, two threads crossing over the thick core from side to side are laced around every third or,fou'rth weft by passing down and up again between two of the sets of leno threads. The wefts are cut by'revolving cutters within say three or four picks of weft of the nip of the cloth. When the weft's are cut they form the pile tufts and the ends heiug released'from the neighboring tufts the cnd s or tufts are drawn upwards towards each other around the core by the tightness of.the cross-ovefthrc ads, into a bottle or flask shape chenille, the upright tufts resembling the neck and the part around the-core resembling the globe of the bottle Our improved woven web into chenille strips during theweaving operation consists of a small shaft supported in a hori-' zontal position immediately over the woven web, andnear the point of weaving, having circular knives fastened on itand spaced apart accurately so as to divide the web as woven'into strips, leaving the The shaft with its cutters is mounted on two stand they may I oscillate backward and forward with the beat-up of the lathe or slay. That is to say, when the lathe or slay goes back for shuttling, the revolving knives follow nearly to the nip of the cloth, revolving all the time, and when the lathe comes forward for the beat-up the revolving knives. move back or away so as not to come in contact with the reed. In order to keep the weftagainst'theedges of the knives, we fix a flat bar to the breast beam, under theweb, and between the breast beam and the shuttle race. On this bar are mounted-projecting brackets which are spaced apart'to correspond with the revolving knives so as to project between them, and which nearly fill the spaces between the knives. At the projecting end of'each cutting mechanism for cutting'the tnfts-practi-" p .the'wefts oithe web 47 to be cut as they are presented bracket are two thin blades or tongues which project still further, so that when the lathe beats the weft in,

the tongues enter spaces left in the reed. The tongues on one bracket are set or spaced ,very near to the tongues on the neighboring brackets, leaving only just enough room for the revolving knives to pass between. As the web is woven the weits are laid over the top edges of the tongues, so that with the forward movement of the blades, while revolving, a scissor like action is produced, .which severs the wefts as they approach the cutters.

2 and 2 are respectively plan, trout and end elevations of the'loom. Figs. 3 and 4 are detailed front and end elevations of the swing circular cutting arrangement for dividing the web as woven into strips of chenille. 5, 6 and 7 are detail views of the mounted projecting.

brackets. Figs.- 8 and 9 are plan and side view respectively of the chenille. 1 V Imthese views, the revolving cutters 36 are shown fixed on a. shaft 37'jou'rnaled in bearings on standards 38 which oscillate on studs 39. The cutter shaft 37 is driven continuously from the back shaft 42 or other' convenient shaft, by a chain wheel 40 and chain 40" which gives motion to a chain wheel 40 mounted upon stud 39; or by any other convenient drive. A spur wheel 40 is combined with the chain wheel 40 and this wheel 40" gears into a spur wheel 40 combined with a chain wheel 40 both mounted upon a stud 40 se'cured to one of the standards 38, the chain wheel 40?, drives by a chain 11 a chain wheel 41 combined with a spur wheel 42 fixed on a shaft 42. The spur wheel 42rgears' into and drives a spur'wheel 43 fixed on the cutter shaft 37 whereby the cutters 36 receive a continuous revolying motion so long as the loom is running.

it the chenilleweb 47 (Fig. 1 is being woven itiis drawn towards the revolving cutters 36 and on. to the thin blades or tongues 12 on brackets 13 which support tothe cutters 36.

The standards 38 with the revolving cutters 36 are pulled'iorward bythe springs 45 so as to be'able to cut theweb as it is woven within three or four picks of welt of the nip of the cloth, and pushed backwards or away from the reed by the rods and springs 46 in order to be away from the reed when the beat-up takes place. The

standards 38 are moved forward and backward by the;

movement of the lathe 48 when beating up. The brackets 13 remain stationary and the projecting blades or tongues 12 enter the spaces formed to receive them in the reed.

The tongues 12 on one bracket 13 are set or spaced very near to the tongues on the neighboring brackets see.

Fig. 5, leaving only just enough room for the revolving cutters 36 to passbetween. As the web is woven in the loom the wefts are laid over the top edges of the tongues,

I of the United States is:

so that with the forward movement of the blades, while revolving a scissor like action is produced. '11 ieh sevet s the weits as they approach the (tillers 34;. There will beonly two, three or four Wel'ts let't uncut. at each stroke. On the top side 0f the projecting brackets 13 a groove 14 in each is formed for-the cut chenille to immediately 1 pass through and as the weits are cut they are thus assisted in the taming up operation. so as to form the pile tufts of the chenille. Q

What: We claim and desire to secure by Letters Patent I In a. chenille weaving loom, cutting mechanism for out 5 line the web while being woven into strips of chenille said uwt-hanlsm consisting of revolving cutters. a shaft carrying the cutters and constantly driven while the l-ooul is running. usz-illatin stantlartls carr \'in; the shaft and 5 \\'lii, 'l| are moved by and with the inove'nient of the llhe.

and stalienary projet-ting hlades for supporting the \vet'ts.

- while being eut hy the ferward movement of the revolving cutters all substantially as and for the purposes herein described.

In testimony whereof we have signed our names to this specification in the presence of two suhst'ribing witnesses.
