SLIVER COILING MECHANISM Filed July 25, 1958 INVENTOR. JOHN S. DUDLEY.

3,032,832 SLIVER COILHNG MECHANISM John S. Dudley, Douglas, Mass, assignor to Whitin Machine Works, Whitinsvilie, Mass, a corporation at Massachusetts Filed .luly 25, 1958, Ser. No. 751,073 3 Claims. (Cl. 19-159) This invention relates to coilers for use with carding machines, combing machines, drawing frames, or with other machines which produce a sliver of textile fibers that is to be coiled into a can. The invention is also applicable to coilers in which a plurality of slivers are coiled into a single can.

It is one object of the invention to provide a stationary member having a defined passageway below the calender rolls, to assure that the sliver from the calender rolls will be accurately conducted into the coiler tube. Another object of this invention is to provide a fixed coiler plate having an anti-friction bearing for supporting the coiler head, so that the coiler mechanism can be operated with less power and at higher speed.

The invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

A preferred form of the invention is shown in the accompanying drawing, which is a sectional elevation showing the invention.

The usual coiler plate is secured to a fixed support M and provides a bearing for the coiler head '11. The coiler head gear is indicated by the numeral 11a. Calender rolls 12 and 13 are rotatable about fixed axes above the coiler head 11 and receive sliver from a trumpet 14 in a fixed support 15. A portion of the sliver can C is shown below the coiler head 11.

The anti-friction mounting for the coiler head 11 consists of an outer race 20 that has a snug or push fit in a recess 21 of the fixed coiler plate 10, and which is held therein by an annular ring 22 that is fixed to the coiler plate by screws 23.

The inner race 24 has a downward extension 25 that is freely rotatable in the opening 26 of the coiler plate 10. Secured to the inner race 24 by screws 27 is the coiler head 11, and the portion 28 of the coiler head 11 is a push fit in the bore of the inner race 24.

Lubricant in the ball bearing is prevented from escaping downwardly by a sealing ring 29. The flange 30 of the ring 22 acts as a deflector to return any lubricant that may escape upwardly, as well as to prevent fly or lint from getting into the bearing.

A fixed member 40 for conducting the sliver into the coiler tube 41 has an opening 42 and side portion 421: that extend upwardly into the bite between the calender rolls 12l3. The member 40 is supported and fastened by a screw 43 in the hub portion 44 of a bracket 45 that is clamped by a screw 46 to a fixed rod 47.

Replacing the member '40 by one with a different size of opening or passageway can be easily and quickly accomplished by loosening the screw 46 and sliding the bracket 45 along the rod 47 until its hub 44 is clear of the tube 41. The bracket 45 can then be swung clockwise so that the member 40 can be removed without interference with the calender rolls.

tent

When a new member 40 of the required size of passageway is placed in the bracket, the bracket is returned to its operative position and again clamped to the rod 47.

The coiler tube 41 is soldered or otherwise secured to a bracket 58 that is fastened to the head 11 by a bolt 51.

Should it be necessary to remove the head 11 from the coiler plate 10, the bolt 51 is first unscrewed, and the combined tube 41 and bracket 50 is lifted out from the head 11. The screws 27 are then unscrewed from the inner race 24, after which the head 11 can be lifted out of the bearing. If the bearing has to be removed, the screws 23 are unscrewed and the ring 22 is removed, after which the entire bearing can be lifted out of the plate 10*.

A usual pair of calender rolls having a fixed axial guide member associated therewith is thus provided. A coiler head is also provided having an improved bearing support and conveniently removable therefrom. Special provision is made to protect the bearing from lint and to protect the sliver from dirt.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:

1. In a sliver coiling mechanism having a rotatable coiler head with a sloping coiler tube secured thereto and calender rolls to supply a sliver to the coiler tube, the combination of an annular fixed sliver guide member adapted to be disposed between the calender rolls and the coiler tube, a bracket, means to secure the bracket to the sliver guide member, a fixed rod parallel to the axes of the calender rolls, and means to mount the bracket on the rod for movement along the axis of the rod and for rotary movement about the axis of the rod.

2. In a sliver coiling mechanism having a coiler head with a coiler tube secured thereto and calender rolls to supply a sliver to the coiler tube, the combination therewith of an annular fixed sliver guide member disposed between the calender rolls and the coiler tube and extending somewhat into the space between the rolls, a bracket supporting said guide member, and means slidingly mounting the bracket and with it said member for movement of the bracket and member in a direction parallel to the axes of the calender rolls while continuing support of the bracket and member for removal of the sliver guide member from between the calender rolls and the coiler tube.

3. A mechanism according to claim 2 in which the means mounting the bracket supports it also for movement in a direction perpendicular to a plane through the axis of the calender rolls.
