My present disclosed and claimed in my copending applicainvention accordingly contemplates feed and suption, Serial No. 161,060. ply apparatus, particularly in connection with To accommodate an adequate number of cans 5o drawing and slubbing frames but useful for any C containing the sliver supply and operatively to 50 lframe Operating on sliver rrlatrral Supplied in position them with a. minimum consumption of cans, such that a greater number of frames may floor space, my invention contemplates an overbe operated in a given mill and may be given an head station for someor all of the cans and prefadequate supply of sliver consistently with existerably at least a major portion of them. According mill space. y ingly I provide at a level above the frame units `55 5 and overlying them a platform I0 extending across both said units and for their full length or substantially so. The platform is at a suiilcient height above the frames to give ample head space, so that an operative may comfortably pass along between the frames in attending them. The platform is firmly supported in any convenlent manner as by means of the uprights or posts I I at the outer sides of the frames and distributed along the latter at suitable points adjacent the frames. The supporting structure of the platform may includes cross members such as girders, beams or the like as indicated at I2 and 1on1- gitudinal beams or girders I3.Av- -As illustratedfthe platform has a low guard rail I4 about its edge, aiding in positioning the cans.

The cans C for the sliver supply for the respective units 5 are located at the opposite sides of the platform I0, arranged along the latter 'in one or more rows, three of which are indicated. inthe drawings. In this manner an aisle. is provided lengthwise the platform, between the two groups of cans,.for trucking fresh cans into position and removing empty ones. It will be understood in this connection that the platforms of adjacent `duplex or other installations in the same room may be connected by bridges or extensions of the respective platforms and that access to the platforms, forv the can trucks, is afforded by ramps or otherwise at convenient locations.

The individual slivers S from the groups of overhead cans are conducted to the sets of drafting rolls I of the corresponding frames 5 by rotary guide means operated in timed relation with the backrolls of said sets. For this purpose I have herein provided a plurality or upper set of rotary guide rolls, three of which are shownin this instance in association with the group of cans for each frame 5, said upper guide rolls being numbered I5, I6 and I'I. They are rotatably mounted as on a bracket or framing I8 carried by uprights I 9 extending upwardly from the platform I0.

The several slivers S at each-side of the apparatus are taken upwardly from their respective cans, through suitable guide formations such. as eyes or slots in a guide 20 on the bracket I8, from which they pass over the inner guide roll I5, down around the intermediate roll I6 and up over the outer guide roll I'I. From the latter the slivers lead downwardly, at each side of the apparatus, herein through confining guides 2| on the platform structure, to the outer rolls 22 of lower sets, lone for each frame unit 5,.and which each include a second and nal guide roll 23. These lower sets of guide rolls are rotatably supported as on brackets 24 on the main frames of the units 5 or on some other convenient fixed part. From the inner guide roll 23 of each lower set the slivers feed directly to the set of drafting rolls "I of the corresponding frame unit.

Both the upper and the lower sets of sliver guiding rolls are driven in such timed relation with the back rolls 8, 8a. of rthe drafting roll set 'I for the corresponding frame unit as to afford an even continuous advancing movement for the sliver. The drive connections for one side of the apparatus are shown separately, on a larger scale, in Fig. 4. As best seen in saidfigure the inner guide roll 23 of the lower set is operated by a belt 38 passing about pulleys on the shaft of said roll and on the lower back roll shaft 8a of the set of drafting rolls 1. The outer guide roll 22 in turn is driven'from the inner one as by the chain 3l passing about sprockets 32 and 33 on the shafts of the Yof the cross members I2; Figs. l to 3.

inner and outer lower guide rolls 23 and 22 respectively. The described drive connections may be located at either or both ends of the roll frames, and at intermediate points if desired, as in connection with specially long frames.

For operating the upper set of guide rolls I5, I6, I'I said lower drafting roll shaft 8a is provided with a sprocket 35 receiving a chain 36. The latter extends upwardly about an intermediate sprocket 31 on a short shaft 38 journaled in a hanger 39 on the platform structure, as upon one Said shaft 38 has fixed on it a pinion 48 meshing with a gear 4I on asecond shaft 42 also journaled in the hanger 39. On said shaft 42 is a sprocket 43 engaging a chain 44 which extends upwardly around a sprocket 45 Xed on the shaft 45 of the inner guide roll I5 of the upper set. The three upper guide rolls I5, I6, II are drivingly interconnected for rotation in unison as by the train of gears 41, 48 and 49 on the shafts of the respective guide rolls.

One or more rows of cans C may be set on the floor behind the roll frame units 5, preferably yclose to and generally partly within the confines of the end frames of said units. In the example shown there is a single row of such cans C along the vback or outer face of the roll frames. The

slivers S from these floor cans are delivered to the drafting rolls by being passed upwardly over the vquired. As stated, in some instances more than a single row of cans may be stationed at the lower level. In any case, however, some of the cans and generally a majority of them, or all of them, are disposed in out-of-the-way position at the upper level as illustrated, thereby freeing the floor space otherwise required and-making it available for additional roll frames or other purposes.

My invention is not limited to the particular embodiment thereof illustrated and described herein, and I set forth its scope in my following claims:l

1. In apparatus for drafting fibrous textile material supplied in sliver form, in combination with a roll frame having a set of drafting rolls including a plurality of upper and lower rolls in paired relation, a platform overlying the frame at a level affording standing room for operatives beneath it and adapted to support one or more rows of sliver supply cans lengthwise the roll frame, a plurality fof guide rolls rotatably mounted above the platform in position to take the individual slivers from cans on the platform and to direct them downwardly, other guide rolls adjacent the roll frame and adapted to receive and forward the slivers to the drafting rolls, and drive means for all said guide rolls for rotating them in timed relation with the back pair of drafting rolls.

2. Drafting apparatus for operating on textile material in sliver form, comprising, in combination, a roll frame, sliver drafting devices thereonincluding a plurality of pairs of coop- -erating upper and lower rolls disposed in tandem,

at least one upper roll rearwardly of the front rolls having a sliver engaging formation compris- 'ing a multiplicity of radial points, drive means intermediate the can position and the draftingdevices, including a plurality of upper guide rolls and a plurality of lower guide rolls for cooperation with each sliver and actuating mechanism associated with the roll drive means and coordinating the latter with the guide and feeding means.

3. Apparatus for drafting fibrous textile ma` terial supplied in sliver form, comprising, in combination, a plurality of roll frames in laterally spaced relation providing an aisle between them, each frame having a set of upper and lower draft ing rolls in paired relation, a platform overlying said frames and aisle at a level affording standing room for operatives beneath it and adapted to support one or more longitudinal rows of sliver supply cans for each roll frame, and, for each frame, a plurality of guide rolls rotatably mounted above the platform in position to take the individual slivers from the cans for the corresponding frame and to direct them downwardly to the latter, other guide rolls adjacent the respective frames and adapted to receive and forward the sliversV to the drafting rolls of the corresponding frame, and drive means for rotating the guide rolls for each frame in timed relation with the back pair of drafting rolls of that frame.
