8 Claims. 1

This invention relates to a, device for winding up webbing from looms on which it is woven. The loom may Weave a number of these webs, for example of the order of an inch or an inch and a half wide, simultaneously. given merely as examples, as other Widths may be woven. Normally each web is wound u on a roll or block, all mounted on a common shaft which is driven by the loom mechanism. However, to take off any coil it is necessary to take off a shaft section with all the rolls, and then each coil of webbing is loosenedso it may be slid from the reel, or it is rewound'onto another reel. It is an object of my device to permit taking off any one or more of the reels of wound webbing desired, without unwinding the web, and disturbing a minimum number of the other reels, thus providing accelerated operation of the loom and the winding device, and greatly reducing the time the loom is not operating due to removing the wound coils and mounting the blocks.

With the foregoing and other objects in view, I have devised the construction illustrated inthe accompanying drawings forming a part of this specification. It is, however, to be understood the invention is not limited to the specific details of construction and arrangement shown, but may embody various changes and modifications within the scope of the invention.

The wind-up device Ill provides a suitable means for winding up the strips of webbing H which are woven by the loom, the front end portion of which is represented diagrammatically by 12, Fig. 1. The wind-up device 10 comprises a series of collapsible reels or blocks 13 mounted on a shaft 14 made in sections and driven from each end by the drive mechanism 15, which may be any of the usual drive means for the wind-up reels or beams, such as a ratchet or like driven from the loom mechanism by the rods 15a. Two sets of four reels or blocks each are shown in Fig. 1, the two shaft sections 25 and 28 supporting these reels being carried in two end bearings 16 and I1 and an intermediate bearing I8. These numbers are shown merely by way of example, as the number of reels in a set may be varied as desired and the number of shaft sections may also be as found desirable.

The bearing 16 is an ordinary bearing, while the bearings l1 and I8 are open on one side, as at l9 (Figs. 2, 8 and 9) so that the shaft [4, or more specifically the individual shaft sections, may be removed by. sliding it out of the bearing through this opening |9.- The shaft 14 is held in the bearings l1 and I8 by the pivoted clips 20 and 21 provided with finger grips 22 and pivoted at 23 at opposite ends of the bearings l1 and I8 so that they may be swung upwardly as at 2|, Figs. 8 and 9,-to release the shaft, or may be swung down as at 20, Figs. 8 and 9, to hold the shaft in place.

The shaft i4 is made in sections, which permits removal from the bearings l1 and [8 of onesec tion without disturbing the other sections. In the form of the device shown in Fig. 1, the shaft H is in four sections, 24, 25, 28 and 2'1, with four winding reels or blocks 13 on each of the two central sections'25 and 26. However, it is to be understood that as many sections as desired may be used, with one or more winding reels l3 at tached thereto.

Theleft end section 24 in the bearing 16 has an. enlarged head 28 with a socket 253 in it to receive the notched end of the shaft 25, the notch being a transverse groove 30 which when seated in the socket 2B, embraces the transverse pin 31 mounted in the enlarged head '28 and extending across thesoc'ket 311, so that as the shaft section 24 is rotated by the drive mechanism 15 it will rotate the shaft section 25'. However, it is clear that the shaft section 25 may be withdrawn without disturbing the shaft section 24.

The shaft section 25 extends to the intermeaeidco vided with a similar transverse rib 32, as shownin Fig. 4, to fit a transverse groove, the same as 33, in the right hand shaft section 21, which is driven by the right hand drive Hi.

The shaft section 25 carries a plurality of collapsible reels or blocks IS on which the webbing H is wound and similarly the shaft sec tion 25 carries a similar series of collapsible reels [3. The collapsible reel comprises two head members or end blocks 34 and 35 mounted on the rotatable shaft section 25 or 26. Between the two end blocks 34 and 35 is the winding drum 36, which consists of two semicylindrical sections separated as at 31, Fig. 11. On the inside of each of these sections of the drum 36 is secured by a suitable means, such as welding or screws (not shown) a channel shaped member 38, located longitudinally of the drum 36.

At the end of each channel and between its parallel sides, levers 39 are pivoted by means of pivot pins 40, the levers 39 also being pivoted by pivot pins 4| between lugs 42 on the end blocks 34 and 35, thus securing the drum 36 to the end blocks 34 and 35. The reel i3 is located at any desirable position on the shaft 25 or 26, by means of a locating collar 43, held on the shaft 25 or 26' by aset screw 44, which permits the collar to be shifted longitudinally of the shaft to any desired location. The end block 34 is placed against the collar 43, and separated from it by a wearing washing 45 composed of fibre or other suitable material. A coil spring 46 embracing the shaft 25 or 25 is placed between the end blocks 34 and 35 so that it tends to push the end blocks 34 and 35 away from each other. Now, however, if the end block 35 is shifted toward the end block 34, the pivots 4| will move toward each other, causing the pivots 45 to move outwardly, and in this manner the drum moves to the expanded position, the sections separating, as shown by dotted lines at 31, Fig. 11. The drum is held in this position by means of a movable collar 48 against the head 35 which is knurled to provide a convenient gripping means, and which is heldin position by a set screw 48a. It is while the drum 36 is in this position that the webbing H is wound on it, the drum being driven by the rotating shaft 25 or 26 through a. friction drive in the end block 34, which consists of a leather plug 52 or other suitable material held against the shaft with any desirable pressure by means of a set screw 50. It is clear that this friction drive enables the shaft 35 to rotate at a greater speed than the drum 36, thus keeping tension on the webbing at all times as it comes from the loom. If desired, the surfaces of the drum sections 36 may be covered with emery'cloth or similar roughened surface material 53 to increase its grip on the web being wound.

When the desired amount of webbing has been wound onto the drum 36, set screw 48a in the collar 38 is loosened and the collar moved to the right, or away from the collar 43. The coil spring 46 then spreads theend blocks 34 and 35 by shifting block 35 to the right. In this manner the pivots 3! move away from each other, causing the levers 29 to contract the drum 36 to the position shown by solid lines, Fig. 11. Lugs 5| on the levers l9 provide a limiting means to prevent the end blocks from being spread farther than desired. When the drum 36 is thus contracted the roll of webbing may be easily removed from the drum without unwinding the webbing, by simply slidin the webbing longitudinally off the drum.

Thus it is clear that with this arrangement all the wound up webbing on the reels [3 at the left of the bearing l8 may be removed without disturbing those at the right hand of this bearing IS, in the following manner: by merel lifting the pivoted clip 23 on the bearing E8, the right hand end of the shaft section 25 may be slid out of the bearing l8 through its open side l9, as shown in Figs. 2, 8 and 9. If the shaft is turned so that the rib 32 is positioned as shown, with one end facing the open side I 9 of the bearing, it may be slid out without disturbing the shaft section 26. Then the left hand end of the shaft section 25 may be withdrawn from'the socket 29 of the left end shaft section 24, and the various coils of webbing removed by collapsing their respective winding drums, or if preferred, the winding drums 36 may be collapsed while the shaft section is still in position, and the coils of Webbing merely slid off the collapsed drums and then off the right hand end of the shaft 25 which has been shifted forwardly out of the bearing l8. Similarly, the other section 26 of the shaft, together with its winding drums l3 and the coils of webbing, may be inserted or removed independently of the shaft section 25, and the coils of webbing may be removed in the same manner. It is therefore not necessary to remove the whole shaft to remove the reels or coils or webbing or any particular reel or coil. Also, the shaft sections can be removed individually without dismounting the bearings or disassembling them. c
