This invention relates to apparatus for handling cloth whichis being woven in a loom and, instead of winding the cloth onto a take-up; roll which is resiliently pressed into engagement with the sand roll of the loom, there is substituted for the pressure roll which engages the sandvroll, a suitable pressure roller which engages the sand r011; and'the'; sand roll, being. driven, feeds the cloth between the sand roll and the pressure roll downwardly through a slot in the floor on-which the loom rests and onto suitable take-up mechanism disposed on the floor below'the floor 'on which the loom rests. This permits the running of an entire warp on the loom yarn beam into a roll of cloth before doffing. It also removes from the aisle between the looms the projecting cloth beam as it builds up to a size where it must be dofied to prevent restricting the passageway or aisle between the looms td'too great an extent.

It is therefore an object of this invention to provide a loom with a pressure roller resiliently held in engagement withthesand for the 'passage'of cloth woverr'by the loom between the sand roll andth'e'pre'ssure roll and extending the cloth downwardly through an elongated'slot in the'fioor to suitable take-up aproll of the loom 2 Claims. :(o1. 139-308) T view taken substantially along the line 1 1 in Figure2.

Referrin more specifically to the drawings; the numeral Hi indicates a conventional loom having a warp beam H, swords lZylay l3, suitable harnesses l4, warp This sand roll is driven in any suitable manner such as by a trainof gearing l1, l8, 'l9'an'di20 and has extending therefrom a shaft 2| loom is also equipped with a suitable mechanism such as is shown in the patent to William Hi .Bahan, Number 2,519,424 of August 22, l950 and' paratus disposed on a floor below where the cloth 7 can be wound into much larger packages than has heretofore been possible in conventional, looms wherein the cloth is woundonto a take-upi'roll resiliently pressed into engagement with the sand I Someof the objects of the invention having been stated, other'objects will appear as the description proceeds when taken in connection with the accompanyin drawings in which- Figure 1 is a'vertical sectional view. through two floors of a building andshowing the apparatusi'nstalled on the floors;

Figure 2 is an enlarged elevation with parts Figure 1; I

Figure 3 is a side apparatus shown in the elevation of the cloth take-up similar to the upper left-hand portion of Figure 1 but showing the parts. in, more detail;

comprisinga torsionally biased shaft" 25' having;

a pinion 26 on each end thereof which'engage's a rack on the lower end of members 21 whose upper ends have suitable notches therein for reception of a cloth take-up roll as set forth in said patent. However, in the present instance instead of a cloth take-up roll there is provided a roller 30,

preferably having a rubber covering 31 thereon, and cloth l5a, resulting from weaving of a suitable filling with the, warp threads 15, passes over I the sand roll 16 and between the sand roll [Sand the pressure roll3'li and then extends downwardly and rearwardly-at an angle, over a rod Mia and rearwardly of the shaft 25 and then through a suitable slot '32 in the floor on whichthe loom It is thus seen that the cloth is not wound onto a clothtake-up roll supported by-the mem-' bers 21 and thus: the size of the cloth 'roll'is' not limited to the distance downwardly which the member 21 canmove;

- The'cloth'roll take-up mechanism disposed low the floor on which the loom rests comprises a framehaving vertical uprights 40 and 1M and

horizontal portions

42 and 43 and diagonal legs 44 and'45, all of which are integral with-each other and are also integral with a platei lfi disj-fv posed on the floor on which the clothtake-up; apparatus rests; The

vertical members

40 and 4| are secured to each other by means of a suitable shaft 41 passing through a tube 48.

On top of the

horizontal members

42 and 43 there are provided bearing blocks 50 and 5| in which

stub shafts

52 and 53 extending from a roller 54 are mounted. On stub shaft 53 is fixed a sprocket wheel 55 having a sprocket chain 56 mounted thereon. Said sprocket chain extends upwardly through a slot 5! in the floor on which the loom rests and is, mounted on a sprocket wheel 58 secured on the end of the shaft Zlextending from the sand roll l6. V

In this -manner,.the rol1 54 is driven by thesand roll and in timed relation thereto. Pivoted on the angle members 44 and 45, as at.60 and SI,

l5 and a sand roll l6. 7

The

and 63, there is pivotally secured to these bars,

as at 10 and H, a second pair of links '12 and 13 which are, in turn, pivoted, as at Hand 75,

to a first pair of links 1'6 and 7'! whose lower ends are fixedly secured on a shaft 18 having an upturned lever 79 integral therewith. The shaft 18 is oscillatably mounted in the diagonal members 44 and 85.

In order to hold the parts of the cloth take-up apparatus in the position shown in Figure 1, there is provided a plate 82 which is welded to thediagonal angle bar d having a notch 83 in its upper end. The lever arm 79 has a projection 84 thereon on which is pivoted, as at 85, a dog or latch 26. Now, when the parts are elevated to the position shown in the lower portion of Figure 1, the dog 88 will ride through a slot 45a in the angle bar 45 and over a sloping portion 81 on the plate 82 and drop into the notch 83 to hold or latchthe parts in elevated position so that, ;as the cloth is built up on the cloth roll, the lap pin 64 along with the cloth roll will ride upwardly on the spaced support bars62 and 53 until the entire contents of the warp beam has been woven or until it isv decided tosever the cloth-and remove the cloth roll from off the angle bars 62 and 68.

When it is desired to do this, the operator seizes the lever 19 and raises the latch 86 which will permit the parts to move, by gravity or by being moved by the crank arm 19, to the position shown in Figure 3 where the cloth roll can be doffed.

It is thus seen that there has been provided simple and inexpensive apparatus for receiving the cloth from a loom at a point remote from the loom without the necessity of the build up of the cloth roll in association with the sand roll narrowing the aisle spaces between the looms and limiting the size of cloth roll which can be woven before dofiing.

-In the drawings and specification, there has been .set forth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being defined in the claims.

I claim:

1. In a 100m having a driven sand roll, the combination of a cloth winding apparatus having a fixed frame, a roll in the fixed frame driven by the sand rol1, a pair of spaced support bars,

said support bars being adapted to support a lap pin, means pivoting one of the ends of the support bars to the fixed frame at points adjacent to but at a lower level than the driven roll, whereby when the free ends of the support bars are moved upwardlythe lap pin will moveiby gravity into contact with the driven roll, an oscillatable shaft mounted in a lower portion of the fixed frame and having a lever fixed thereto, a first pair of links having one of their ends secured to the oscillat-able shaft, a second pair of links having their upper ends pivotally secured to the 1 support bars,.means pivotally securing the lower ends of the second pair of links to the upper ends of the first pair of links and means for latching the lever against movement when the first and second pairs of links are in alinement with each I other.

2. A cloth winding apparatus having a fixed frame, a driven roll in the fixed frame, a pair of, spaced support bars, said support bars being adapted to support a lap pin, means pivoting one of'the ends of the spaced support bars to the fixed frame at points adjacent to but at a lower level than the driven roll whereby when the free ends of the support bars are moved upwardly, the lap pin will move by gravity into contact with the driven roll, an oscillatable shaft mounted in a lower portion of the fixed frame and'having a lever fixed thereto, a first pair of linkshaving one of their ends secured to the oscillatable shaft, a second pair of links having their upper ends pivotally secured to the support bars, means pivotally securing the lower ends of the second pair of links to the upper ends of thefirst pair of links and means for latching the lever againstmovement-when the first and second pairs of links ar in alinement with each other.
