Claims.

my invention relates to a cloth roll attachment for looms and is particularly adapted for lace looms whereby the material as it is woven on the loom is rolled onto cores forming rolls of material of such size as may be conveniently handled for use in other operations, resulting in the complete manufacture of the cloth into ourtain lengths.

Anotherand further object of my invention is the provision of a rolling mechanism which draws the material through the weaving mechanism of the loom and rolls it onto a paper tube or core of a length corresponding to the width of the woven material so that rolls of material in convenient form can be transferred to other parts of the mill for such finishing operations as may be desirable or necessary.

Another and further object of my invention is the provision of a. rolling mechanism for the purpose of rolling the woven material into rolls which are tightly and evenly wound on the rolls thereby keeping the material in compact form for easily handling the material for further manufacturing operations in the mill.

Another and further object of my invention is the provision of a mechanism which through the use of paper tubes as cores onto which the Woven material is rolled, the handling of the woven material from the looms is facilitated and the time necessary to change the rolls from the looms is very materially shortened thereby se-' curing greater productivity of the looms than what has been possible heretofore.

In the operation of the average curtain loom,

which is usually some thirty odd feet in width;

curtain material of predetermined widths is woven on the looms and heretofore it has been the custom to wind this material on a mandrel, which formed a part of the loom itself. When a sufficient quantity of material had been woven to provide a roll of adequate size, the loom" was stopped, the material unrolled from the roll and placed into bags for such further operations as was necessary to convert the woven material into curtains. The curtain material is woven in long lengths, and its removal from the mandrel would take a considerable amount of time resulting in a closing down of the loom and a loss of valuable time in the weavingoperations. With my improved cloth roll mechanism the material can be cut at any time and the roll of material on the hollow core removed as aunit, a new core substituted, a length of material wound around itand placed in position on the 2 Winding mechanism and the operation of weaving continued in a very short period of time.

It requires only a very small amount of time compared with the time lost in the operations of the loom heretofore and results in placing the material in such form and condition immediately speed to take up the material ,being woven on;

thevloom regardless of material.

These andother objects of my invention will be more fully and better understood by reference to the accompanying sheet of drawings and in which: i

Figure 1'is an elevational view of a cloth roll attachment in position on a lace loom;

the .size of the roll of Figure 2 is an elevational view of the rolling mechanism showing the driving attachment with the two support rollers; and

Figure 3 is a view. partially in section. and

partially in elevation through a loom showing particularly the brackets for the'support rolls intermediate their ends'the two support rollers and the cloth roll cradled thereon. V

Referring now specifically tothe drawings and in which like reference characters refer to' like.

parts throughout, a loom frame Ill is shown havinga bracket H mounted thereon to which is attached the usual nosepiece l2 above the usual bobbin [3 with warp threads l4, !4 being shown, the filling threads beingomitted as they form no part of mypresent invention.

The material is woven into final format the lower point of the nosepiece l2 as is common with looms of this particular type. and char-.

acter. ,A porcupine roller l5'is provided, this roller l5'being made'up of a shaft it having a gear wheel i! on the outer end thereof at one of its ends supported vby pillow blocks l8, 58 secured to the frame Ill of the loom at each of its ends with intermediate supporting brackiets l9, I9 being provided which are secured to the loom frame I!) in any approved manner. and

have divided ends with cradles 2i! and 2! at the.

ends thereof. The porcupine roller I5 has a core 22mounted on the shaft i6 and overwhich card cloth 23 is placed to form the porcupine roller l5 for taking up the material from the loom with the core 22 being mounted in the cradle formed at the ends of the brackets l9, l9 and being driven through the gear connections with the operating parts of the loom with the gear wheel If L which is connected to suitable driving mechanism of the loom and normally operates a roller on which the woven material is wound after being woven in the normal operation of the loom. 7

Also mounted on the frame of the loom is a combined support and friction roller M this roller comprising a shaft 25 which'ex'tends parallel with the porcupine roller (5 and which animated in pillow blocks 25, 26 secured to the frame iii of the loom at each of its ends. This support roller 24 also has a core 2'! through which the shaft 25 extends over which a layer of cork 28 'is placed to povide a friction surface to the roller 25 with the core 21 being supported in the cradle 21 formed inoh'e of the divided ends of the supporting brackets I9, 18. The roller 2 is parallel with and spaced a'slight distance from the porcupine roller 15 so that in eifect these two rollers form a cradle for the roll of material 29 wound about the hollow core 38.

A sprocket wheel 3! is mounted on the shaft is on the end opposite the gear wheel II, this sprocket wheel in the form shown having thirtyone teeth thereon with a second sprocket wheel 32 being monntedon the'shaft 25 in'alig'nment with the sprocket 3i, this sprocket wheel 32 being smaller than the sprocket wheel '31 and 'in'the form shown having nineteen teeth thereon, the two sprocket wheels being connected tdgether'by me'anisof a sprocket chain 33 so the roller 24 is driven from the sprocket 3i and rotates in the same direction as the sprocket 3| and at an increased peripheral'speed of rotation greater than that of the porcupine roller 55 which, of course, rotates at the samespeed as the sprocket 3! because of its being mounted on the same shaft 'l 5 as the sprocket 3|. As the cloth is taken upon the roll 28, the mu-er 33 bein'g driven at a higher speed than the porcupine roll has a tendency to drive the cloth roller faster thereby keeping the material taut on the cloth roller'and alsopulling the material clear of the porcupine roller 33.

A side roller is provided which merely guides the material'at one'edge thereof onto the roll at the'end of the rollers and keeps the'end roll'material in alignment.

In operation of the apparatus the hollow tube or core 38 is provided around Whicha few turns of the free end of the material is wound, is placed incradled position on the tops of the porcupine roller l5 and the friction roller 33. These two rollers are spaced apart a sufficient distance to form cradles for the cores, it being common to weave a plurality of widths 'of'curtain material on these looms sometimes six in nu'mbefdepending on the width of the material desired, so that each width of material is supplied with a core which is placed in cradled position on the porcupine roller l5 and the friction roller 24. If six widths of material are being used, then six of the hollow cores must be placedin position on the rollers l5 and 24 with the "woven material being placed around the porcupine -roller"l 5which normally rotates in a counterclockwise direction as viewed in Figures 2 and 3 with thematerial being initially wound on the cor'e' tfll in acl'ockwis'e direction with the necessary number of turns of material thereof placed in position so the material will not unwind. The weaving operation of the loom is thereupon commenced, and as the material is woven, the porcupine roller 15 is rotated through the gear I! pulling the material from the loom. The roller 24 is also rotated through the sprocket wheel 3|, chain 33 and sprocket 32, with the porliupine roller l5 and friction roller 25 rotating incounterclockwise directions as seen in Figures 2 and 3, and because of friction the core 39 with the few turns of material on it (a small cloth roll) also is rotated in 'a clockwise direction taking up the material as fast as it is woven. The friction roller 24 turns at raster periph'eral'speed, as heretofore explained than glo'estlie porcupine roller l5. There is 'a'tendency for the cloth roll 29 to rotate at the same speedas thefriction roller 24 but this is prevented by thematerial, although this pulling force on the material lifts the material clear of the porcupine roller l5 and causes the material to be 'tightlywound-onto a cloth "roll 29. There i's'a slippage between the cloth roll and the friction roller 2 of course, but this is immaterial. The operation of the loom may continue until the cloth roll -25 reaches a desirable size when the material is cut and-the cloth roll'removed from the loom. The peripheral speed of thecloth roll 29 is the same, of course, whether the rolli's'smal-l or large and is constant, being timed by the m operations through the gear 'I 'I, When "the material is cut, a sufiiciently free end is left to be initially wound on a new core, and the weaving operations are proceeded'with until a new cloth roll 2a is produced, so fares-the winding of the woven materialis'concerned. l

While I have described more or less precisely the details of construction, -I donot wish to be understood as limiting myself thereto, as I contemplate changes in form and the proportion of parts and the substitution of 'eqiuvalents ascircumstanoes may suggest or render expedient without departing from the spirit or scope ofmy invention. v Y V l What is claimed is; o I v 1.
