RING SPINNING AND ANALOGOUS MACHINE Filed t. 20, 1931 5 Sheets-Sheet 3 nd J David T Viizrlwusa,

ATTORNEY 1y movable ring rail carrying rings 3 upon as 14 depending from each of which is the usual traveller 4. The spindles (not shown) are driven by whorls 5 and carry spools such as 6.

The ring .rail 2 is supported upon lifter spindles 7 at the upper end of each of which is a cross-head 8, the lifter spindles 7 passing through apertures in the spindle rail 1 and each having at its foot a dog such as 9 connected by means of a chain 10 to the chain rod 11, each chain 10 passing by way of jockey pulleys to and over a pulley 12 mounted on a pulley plate 13 which is attachedto the spindle rail 1 by brackets such said spindle rail and bolted thereto at 15.

Referring now to Figures 2 and 3, the spindle rail 1 is carried by the lifter spindles,

16 at the foot of each of which is a dog such as '17 to which is attached one end of a chain 18 whereof the other end is secured to a collar 18w fast on a stud 22 mounted suitably on a, fixed part of the frame.

From the point of its attachment to said collar 180, each chain 18 first passes over a scrollor spirally grooved roller 19 secured upon a continuousrotary shaft 20 and then each of said chains 18 passes over a guide pulley 21; also mounted upon the aforesaid stud 22 and thenceto the dog 17.

23 is the rod end iron, the contact face 23a of which is so shaped as to permit the chain rod 11 to have a certain amount of vertical movement inv addition to its normal longitudinal movement, said chain rod 11 being forked at its end to accommodate a roller 24 which contacts with the face 23a of said rod end iron 23.

v The aforesaid continuous shaft 20 receives rotation through the medium of the buildergotion gearing 25, 26, 27 and the gear wheel 25 is the driving wheel mounted on the sleeve 25a on the screw shaft 25?).

The gear wheels 26 and 27 are mounted on stud 28 (see Fig. 5) which is carried suitably by the frame end, and the gear wheel 29 is carried bythe continuous shaft 20.

During the first half of the building operation the scrolls 19 rotating within the bights or loops of the respective chains 18 are so designed as to maintain the effective length of each chain 18 constant, but, during the remainder of the building operation gradually to lengthen each chain 18 thus lowering the spindle rail 1 and preventing the balloon of the yarn from becoming too short.

It will therefore be apparent that, by

means ofthe above described apparatus, if the ring rail 2 is, say 4 inches higher than the spindle rail 1 at the commencement of the building operation, and

if 10 inch spools are bemg built, when the buildis coinpleted the ring rail 2 will be 14 inches higher than the spindle rail 1. When the building operation commences, the spindle rail 1 is in the normal position where it remains until the ring rail 2 is, say, 9 inches higher, that is to say half way, at which point the scrolls 19 commence to cause the spindle rail 1 to lower at exactly the same rate of speed as the ring rail 2 is traversing and without interruption of the relative movement of the ring rail 2. 5

In this manner the difiiculties incidental to the building of the larger packages referred to above are overcome and the best conditions for spinning, twisting or the like are maintained throughout the build.-

What we claim is: i 1. In ring spinning and analogous machines including a spindle rail, spindles carried by said spindle rail, a ring rail, rings carried by said ring rail, a builder motion having a rod end iron, and a chain rod actuated by said builder motion through said rod end iron, said spindle rail and said ring rail both being movable. vertically; means controlling the movement of said ring rail suspended from said movable spindle rail, and means controlling said spindle rail so as at a certain point in the operation of said builder motion, to lower said spindle rail together with the ring rail and chain rod at the same rate of speed as said builder motion traverses said ring rail.

2. In ring spinning and analogous '1nachines including a spindle rail, spindles carried by said spindle rail, a ring rail, rings carried by said ring rail, a builder motion having a rod end iron, and a chain rod actuated by said builder motion through said rod end iron, said spindle rail and said ring rail both being movable vertically; lifter spindles supporting said ring rail, said lifter spindles being supported by chains from said movable spindle rail, and means controlling said spindle rail so as, at a certain point in the operation'of said builder motion, to lower said spindle rail togetherzwith the ring rail and chain rod at the same rate of speed as said builder motion traverses said ring rail. v

3. In ring spinning and analogous machines including a spindle rail, spindles carried by said spindle rail, a ring rail, rings carried by said ring rail, a builder motion having a rod end iron, anda chain rod actuated by said builder motion through said rod end iron; said spindle rail and said ring rail both being movable vertically; lifter spindles supporting said ring rail, said lifter spindles passing through said spindle rail and being connected by chains to said chain rod, each of said chains being engaged by a pulley adjacent said chain rod, said pulley being supported by said spindle rail, and means controlling said spindle rail so as at a certain point in the operation of said builder motion, to lower said spindle rail together with the ring rail and chain rod at the same rate of speed as said builder motion traverses said ring rail.

4. In ring spinning and analogous ma-V chines including a spindle rail, spindles carried by said spindle rail, a ring rail, rings carried by said ring rail, a builder motion having a rod end iron, and a chain rod actuated by said builder motion through said rod end iron; said spindle rail and said ring rail both being movable vertically; lifter spindles supporting said ring rail, said lifter spindles being suspended by chains from said movable spindle rail, lifter spindles supporting said spindle rail, said spindle rail lifter spindles being suspended by chains passing over s irally grooved pulleys, and means control ed by said building motion to rotate said pulleys so as, at a certain point in the operation of said builder motion, to lower said spindle rail together with said ring rail and chain rod at the same rate of speed as said builder motion traverses said ring rail.

5. In ring spinning and analogous machines including a spindle rail, spindles carried by said spindle rail, a ring rail, rings carried by said ring rail, a builder motion having a rod end iron, and a chain rod actuated by said builder motion through said rod end iron; said spindle rail and said ring rail both being movable vertically; in combination, means suspended from said spindle rail for controlling the movement of said ring rail, a rod end iron constructed so as to engage said chain rod when the latter has vertical movement as Well as the normal building movement, and means controlling said spindle rail to cause it to remain stationary during a portion of the operation of said builder motion and to cause said spindle rail to be lowered during the remainder of said operation.

In testimony whereof they aflix their signatures.
