1 Claim.

The present invention relates to a loom attachment and particularly relates to a loom attachment for disposing of exhausted quills and for denuding said quills of the residual filler 5 or weft thereon.

h1 the usual type of loom, particularly of the automatic variety, it is necessary for the operator or weaver when the shuttle is exhausted to remove the quills from the shuttle and place such quills in a box or receptacle at the front of the loom.

Usually, it is also` necessary for the weaver to remove the residual filler or weft still remaining on the quill.

L At intervals assistants usually come along the row of looms and remove the exhausted cops or quills and return them to the winding room where they are rewound with weft or filling and where '20 they are separated` according to the color or according to their particular weft or filler which they are designed to carry.

With automatic looms costing a relatively large' amount oi money and designed primarily to save the operators time and primarily advantageous in that they enable the operator or weaver to attend a larger amount of looms than would otherwise be possible, this operation of removingthe residual filling or weft from the quills consumes considerable time and also slows up the operation and detracts from the desirable effects of the automaticity of the loom.

It is, therefore, among the objects of the present invention to provide an improved loom at,- tachment for automatic looms but which is also designed for other types of looms in which the quills from exhausted shuttles may be substantially or partly automatically denuded of the ller weft and at the same time disposed of at a suitable place and position where they may be readily collected in diierent colors without interference with the weaver or operator of the looms.

Another object of the present invention is to provide an improved quill disposer which will i be susceptible of ready association with the loom without substantial reconstruction thereof and Without interference with the normal operation and control of the weaving operation.

`Other objects will be obvious or will appear during the course of the following specication. In accomplishing the above objects, it has been found most satisfactory to provide a plurality of conduits or tubes preferably one for each particular type of quill or cop into which may be dropped the exhausted quill or cop.

At the lower ends of the tubes or conduits may be positioned collector boxes in which the respective exhausted quills or cops may be col- 5 lected.

With the usual type of automatic loom having an elevated fresh quill or copsupply it is generally most desirable to position the inlet to the q tubes adjacent such supply board and then to lo have theV tubes incline downwardly toward the rear` of the 'loom where the collector boxes may be positioned and where the exhausted quills or cops may be removed by the collector boys a without interference with the weavers.

To remove the .residual ller or weft upon the quills the loose end of the residual ller or weft may be clipped or tied at the inlet end of the tube and the tube may then be dropped through the tubes which would cause .such filler to unwind.

Since the'ller usually may be longer than the` length ci the tube, it has been found most satisfactory to provide a rotating lswift coney or .25 other device which will have the effect of catch- Y ing the ller and winding it up upon 'the cone swift or other device from which it may be readily removed without difficulty.

This will position the quills or cops without residual ller in the collector boxes vat the rear of the loom and make the collection operation and the replenishment of such quills much simpler.

In the drawings which show several of the various possible embodiments according to the present invention but to which the invention is by no means restricted, since many changes or alterations may be made thereinall within the scope of the present invention or Without departing from the spirit thereof:

Figure 1 is a perspective viewrof the loomv construction showing the manner of assembling and positioning the attachment of the present invention thereon;

Figure 2is a side elevational View of the loom showing the attachment of the present invention and particularly the device for taking up the excess and residual weft;

Figure 3 is a fragmentary perspective view 50 of the driving mechanism.

Referring-to Figure l, the loom is provided with q the frame Il), with the take up roll l l, with the, control levers I2, with the lay I3, the heddles i4, the heddle control mechanism l5, i6 and 55 l1, with the shuttle boxes I8, with the shuttle magazines I9, and with the automatic shuttle changing mechanisms and 2l.

To the rear of the loom is positioned the main shaft 22, which passes through the clutch 23 and which drives the auxiliary shaft 24 provided with the hand wheel 25.

Above the magazines 20 is positioned the fresh quill carrier 2S carrying the fresh quills 2l. v

Ordinarily, With the type of loom shown in Figure 1, when a shuttle is exhausted, it would be pressed outwardly upon the shelf 28,` into the box 29, Where the operator will remove the exhausted quill and replace it by a fresh quill 21.

It is to the disposal of these exhausted quills that the present invention is most particularly directed.

As shown best in Figure 1, from the bar 30 supporting the board 26 extends a rectangular frame structure having the front member 3|, the back member 32 and the bars 33 and 314. From the bar 34 extends the support bar or rod 35 to which is clipped at 36 and 3l the upper ends of the tubes 3d and 39, the mouths 40 and 4l of which are positioned closely adjacent the board 2S, as indicated.

These tubes 38 and 39 extend downwardly and rearwardly to the collector box 42 having the compartments Allt and 44 in which the exhausted quills are disposed.

Usually separate tubes 33 and 39 are provided for each diiierent type of webt which is employed so that in each compartment 43 andli there will be collected one type of quill each one of which is to receive the desired type of filling.

If desired, a clip or hook might be provided adjacent the upper ends of the tubes 33 and 39 upon which the end of the iilling might be tied, so that the illing will be unravelled or unwound from the quill as the quill drops from the tubes 38 and 353.

However, if the length of the tubes 38 and 39 is not sufficient to unravel all of the residual weft or lling, it has been found preferable to provide an unwinding device such as a swift, a cone or some other device for winding up the residual lling or weit.

In the construction shown, a cone 45 is rotatably mounted at t6 upon the forward extension 4l of the side bar 34.

The cone is provided with the pulley 48 which carries the belt 49 connected to the pulley 5|).

The pulley 5d is rotatably mounted upon the v bar 5l supported upon the bar 34 at 52..

The rotating shaft 53 is rigidly connected to the pulley du and also to the pulley 54 which is mounted upon the bar 55 connected to the bar 33 at 56.

The pulley 5E carries the belt 5l which is driven by the pulley 58 upon the shaft 59 which carries the hand wheel and which is driven by the shaft element 24.

In operation, when the operator removes an exhausted shuttle from the box 2g, he iirst places the new quill in position and replaces the shuttle in the magazine |53.v Then the loose end of the residual weft is pressed on to the revolving cone 45 which will pick it up and the quill, de'- pending upon Whether it is a left or right turn and also depending upon the character of the weft lling is dropped through one of the tubes 38 and 39 into the collector box 42.

If the amount of residual weft or ller left on the quill is greater than the length of the tubes 38 and 39 the revolving cone 45 will unwind the remaining weft leaving the denuded quill in the basket 42. 'Ihe weft or ller thread on the cone 45 may then be easily removed.

From the collector box 42, the exhausted quills are now denuded of their residual weft or filling, and they may be collected by boys passing behind the looms where they will not interfere with the weavers.

It is apparent that the speciiic illustrations shown above have been given by Way of illustration and not by way of limitation and that the structures above described are subject to wide variation and modification without departing from the scope or intent of the invention, all of `which variations and modifications are to be included within the scope of the present invention.

What is claimed is:

In a disposal system for exhausted quills for use with an automatic loom of the Ashuttle changing type having a shuttle changing box at one side of the loom, an elevated board at said side of the loom carrying fresh quills, a raceway for receiving exhausted shuttles below said box at said side of the loom, and a receiving box to receive said exhausted shuttles from said raceway; said system including two tubes having elevated inlet ends substantially above said raceway and closely adjacent said elevated board at the upper front portion of the loom and having outlet ends at the rear of said loom adjacent the floor, said tubes extending obliquely downwardly along said side of the loom, a collector box at the rear of the loom having a plurality of compartments receiving the outlet ends of said tubes, one outlet end being positioned in each compartment, the exhausted quills being collectible fromsaid collector box at the rear of the loom without interference with the weaver working at the iront of the loom, and means located substantially above said raceway and positioned at the inlet ends of the tubes to remove the residual iilling from the exhausted quills which may be placed in said inlet ends, said last mentioned means having an element to grasp the end of said residual iilling when said quills are placed in the inletrends of said tubes and to remove said exhausted filling from said exhausted quills when said exhausted quills are falling through said tubes.
