GOSSELIN FILLING RETAINING DEVICE FOR LOOMS Filed Sept. 19, 1930 2 Sheets-Sheet 2 Patented Oct. 11, 1932 PATENT; OFFICE ABRAHAM GOSSELIN, OF FISHERVILLE, MASSACHUSETTS FILLING RETAINING DEVICE FOR LOO'MS Application filed September 19, 1930. Serial No. 483,048.

The present invention relates to an improved device for retaining the filling threads of looms, andit has particular application to looms Weaving a fabric embodying what 1s known in the art as a dot filling, that is, an extra filling woven into the ground fabric.

The obj ect of the invention is to provide a device of the above indicated character that is adapted to engage the ends of a dot filling when the lay is rearward and which will automatically'move out of the path of the lay to release the filling when the latter is beat up by the lay. In other words, the reta 1n1n g device is operative only when the dot fillmg 1s being laid and is automatically moved to re- 1 lease the filling when the lay moves the dot filling thread into proper position in the fabric. I g v p A further object of the present invention is to provide means for automatically renderlng the entire retaining device inoperative when the shuttle boxes of the loom are moved to stop the weaving of the dot filling in accord ance with the pattern control, the device automatically resuming its previous operation when the shuttle boxes are again shifted to resume weaving of the dot filling. The above and other advantageous features of the invention will hereinafter more fully appear with reference to the accompanying drawings in which Fig. 1 is a view in side elevation showlng a portion of a loom to which the device is applied. I

Fig. 4 is a plan view of the parts shown in Fig. 3.

' Fig. 5 is a sectional view along the line 5-5 of Fig. 3, looking in the direction of the arrows.

Like reference characters refer to like parts in the different figures.

Referring first to Figs. 1 and 2, the portion of the loom shown comprises the usual side frames 1 between which is mounted a shaft 2 carrying upwardly extending pivoted arms or lay swords 3 supporting the lay 4, with a plurality of shuttle boxes 5 vertically movable on the lay by a lifter rod 5a. The side frames also support a breastbeam 6 with respect to which the lay 4 is moved back and 5 forth in the usual manner, when weaving.

As best show in Figs. 8 and 4, the breastbeam 6 carries on its rear face a plurality of brackets 7, 7 for rotatably supporting a rod 8 extending across the face of the breastbeam 6. The rod 8 carries a pair of arms 9, 9, adj ustably secured on the rod 8 by means of set screws 10 and the upper end of each arm 9 carries a filling retainer 11. Preferably, .each retainer 11 is composed of a length of wire bent sidewise and then rearwardly and terminating in a downwardly bent filling engaging portion 11a, somewhat pointed by flattening and providing a notch 11?) at one side. The form of the retainer 11 is such 7 that it extends clear of the adjacent loom temple 12 with its pointed end extending downwardly in advance of the temple. By reason of the adjustable mounting on the arms 9 on the rod, the retainers 11 can be set at any desired distance from the outer edge of the fabric being woven, for a purpose which will hereinafter appear.

The rod 8 is surrounded by a coiled spring 13 with'one end secured to a bracket 7 and its other end secured to a collar 14 mounted on the rod 8, a second collar 15 preventing longitudinal movement of the rod. The tension of the spring 13 tends to turn the rod 8 in a clockwise direction as viewed in Fig. 5, so as to normally maintain the pointed end 11a of the retainer 11 in position to retain the filling being woven and the invention contemplates means for automatically raising the retainers 11 to release the filling each time the lay 4 moves towards the breastbeam 6 to beat up a dot filling thread, and also to render the device entirely inoperative when the ground filling of the fabric is being laid.

As best shown in Figs. 3 and 5, one end of the rod 8 provides an upwardly extending operating portion 16 which, when the spring 13 holds the retainers 11 in the filling engag ing position, is inclined rearwardly in the dimotion of the lay 4. When the lay 4 moves toward the breastbeam 6 following the operation of the shuttle, a lug 17 on the lay 4 engages the operating portion 16 and moves it into the dotted line position of Fig. 5. WVhen this occurs the rod 8 is turned in a counterclockwise direction thereby raising the pointed portions 11a of bothfilling retainers 11 into the dottedline position, out of engagement with the filling thread. Upon return of the lay 4 to its rearward position, the spring immediately turns the rod 8 in a clockwise direction since the operating portion 16 is then free of the lay. This turning movement of the rod 8 causes the pointed portions 11a of the retainers 11 to simultaneously engage the filling-thread, so that when the shuttle again operates a loop will be formed around the end portion 11a of a retainer 11, the thread catching in the notch 11b to retain it. Obviously the above de scribed operations will be repeated upon each complete back and forth movement of the lay 4, so that a loop is formed each time a dot filling is laid in the fabric.

As previously pointed out, the arms 9 carrying the filling retainers 11 are adjustable longitudinally of the rod 8 and the purpose of this adjustment is to conserve the amount of dot filling used. It will be readily appar-.

ent from Fig. 2 that the retainer carrying arms 9 can be set on the rod 8 so as to bring the filling engaging portions 11a of the retainers near to the point where the dot filling is being woven. Since this adjustment is effected independently of the loom temples 12, it is possible to form the loops in the dot filling at any desired distance from the edge of the fabric. As shown in Fig. 2, the arms 9 are so adjusted as to bring the pointed ends 110; of the retainers 11 a considerable distance inside the selvage so as to reduce the length of the loops in the dot filling to a minimum.

Referring now to Fig. 1, there is shown in connection with a portion of'the loom the arrangement whereby the filling retainers are rendered entirely inoperative to engage the filling when the ground filling of the fabric is being laid. To this end a vertical rod 18 is provided, the upper end of which is out of engagement with an extension 19 of the rod 8 when one of the upper boxes 5 is supplying dot filling. However, upon the operation of the pattern control to raise the boxes 5, and thereby bring the ground filling in position for weaving, the rod 18 is moved upwardly between the breastbeam and the extension 19 of the rod-8 then in the retracted position shown in dotted lines in Fig. 5. Since this movement of the rod 18 occurs when the lay 4 is in position to beat up the last laid dot filling, the retainers are in their raised position out of engagement with the filling, consequently when the lay 4 moves rearward, to lay a ground filling in accord .ance with the shift of the boxes 5, the upper end of the rod 18, shown in dotted lines in Fig. 1, prevents the extension 19 from mov ing to the left, as it otherwise would. Obviously this engagement of the extension 19 with the rod 18 prevents the spring from turning the rod 8 to bring the retainers 11 into the filling engaging position. .There fore, the entire filling retaining device remains inoperative as long as the ground filling is being laid, the rod 18 remaining in its raised position until the pattern control causes the boxes 5 to be lowered.

As shown in Fig. 1, the rod 18 is connected to the rocking lever 20, which controls the position of the boxes 5 by means of an extension 21 supporting the rod 18 at its lower end. The lever 20 is also connected to the box rod 5a by means of a givewaylink 22 of well known construction, so that the lever 20 determines the position of the box rod 5a in the pivoted bracket or stand 23. Therefore, turning of the lever 20 to raise'the boxes 5 imparts upward movement to the rod, as shown in dotted lines, and obviously when the lever 20 is turned in the opposite direction to lower the boxes 5, the rod will be moved downwardly to clear its upper end from the extension 19 and permit the spring 13 to turn the rod 8 and swing the retainers 11 into their filling engaging position.

From the foregoing, it is apparent that by my invention there is provided an extremely effective device for retaining the dot filling threads of a fabric, as it is woven, in such a manner as to reduce the amount of waste filling to a minimum. In addition the device provides automatic means for rendering the filling retainers inoperative when the dot filling is not being woven.

I claim: i
