MACHINE FOR DOUBLING AND TWISTING YARN.

SPECIFICATION forming part of Letters Patent No. 775,550, dated November 22, 1904.

Application filed April 14, 1904.

To all whom, it may concern:

Be it known that I, BENAJAH S. ALLEN, of Dedham, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Machines for Doubling and Twisting Yarns Direct from Skeins, of which the following is a specification.

Figure 1 represents in front elevation a machine embodying the invention. Fig. 2 represents an end elevation thereof. Fig. 3 represents a partial vertical section of the machine from front to rear. Figs. 4, 5, and 6 represent the improved skein-holder or reel. Fig. 7 represents a novel ring which is employed upon the machine.

, It is common practice in textile mills after the yarn has been spun to wind it upon reels in the form of skeins. Then the yarn is spooled, after which itis doubled and twisted. These various steps add considerably to the cost of manufacture, and the employment of the various machines required takes up a relatively large area of the floor-space in the mill.

The present invention has for its object to perform in a single operation the doubling, twisting, and spooling directly from the skeins.

On the accompanying drawings a frame is shown having end standards 10 and 11, which are suitably connected and braced. The spindle-rails are indicated at 12, and they are stationarily secured to the standards 10 and 11. The spindles 13 are driven by bands 14 from a drum 15, secured upon a shaft 16, which is journaled in the standards 10 and 11 and is arranged-midway between the spindle-rails. The drum-shaft 16 is provided'with fast and loose pulleys 17 18 and is driven directly from the counter-shaft. The ring-rail is indicated at 19, and it is supported by the upright rods 20, arranged to slide in guides which are provided for their reception. The lower ends of these rods are supported by levers 21, each fulcrumed intermediate of its ends, as at 22. Each lever has at its rear end a block 23, resting upon a suitably-shaped cam 24, secured to a shaft 25, journaled in the end standards 10 and 11. Said shaft is rotated to rock the levers 21 about their fulcrums to raise and or standards 39.

lower the ring-rails 19 in alternation, the said shaft being driven from the drum-shaft 17 by the following mechanism: On its end said shaft 16 has a bevel-gear, 26, intermeshing with and drivinga bevel-gear 27 on a shaft 28, which runs from front to rear of the frame outside of the standard 10. At one end the said shaft is provided with a bevel-gear 29, int-ermeshing with and driving a similar gear 30 upon an upright shaft 31, on the lower end of which is a bevel-gear 32, intermeshing with and driving a bevel-gear 33 on the end of the shaft 25. The rings 34 are relatively large, each ring having upon its upper end a race 35 for the reception of a traveler 36. At its lower end each ring is provided with a flange 37 and ear 38 integral with said flange and which may be secured by screws or bolts 39 directly to the rail 19, as shown in Fig. 7. The rings therefore project forward or rearward, as the case may be, from the ring-rail, so as to encircle the spindles. Upon the top 38 of the frame are supported a series of uprights or standards 39, each formed with a plurality of forwardly and rearwardly projecting arms arranged one above the other. The lower arms are indicated at 40 and the upper arms at 41, the latter being hinged thereto, as at 42, and adjustable about their pivots to raise or lower their outer ends and to thereby move their ends toward or from the said uprights In the end of each arm is a stud-shaft 43 for the reception of the hub 44 of a reel. hub a series of grooved and slotted arms 45 for the reception of sliding spokes 46. These spokes are adjustable radially of the reel and are adjustably secured by any suitable fastening means, such as indicated at 47.

The end of each spoke 46 is reduced, as at 48, and has secured to it a spool 49. The arms 46 and the spools 49 are preferably made of wood, whereas the hub and radiating arms may be made of metal. Each spool 49 has a cylindrical body portion 50, with flanged ends 51 52. In the end 51'is a socket 53 for the reception of the reduced end 48 of the yoke, which is secured therein by glue. In this construction the spools or skeiu-supporting members project laterally from the reel-spokes and Each reel has radiating from its before referred to.

are supported only at their ends, making it convenient for an operator to have access to a skein. 1

The yarn is led from the reels, which are thus arranged one above the other between rolls which draw it therefrom. The lower roll is journaled in brackets 56 at the ends of the frame. The brackets support a longitudinal bar 57, with smaller brackets 58 secured thereto at intervals, in which are journaled the top rolls 59. The bar 57 affords a convenient means for supporting angular yarn-guides 60, having eyes 61 at their ends, which are arranged substantially over the axes of the spindles.

Each roll 55 has upon its end a bevel-gear 62, intermeshing with and driven by a bevelgear 620 upon an upright shaft 63, which is supported outside of the end standards 10.

The shafts 63 have upon their lower ends the bevel-gears 64:, one of which intermeshes with and is driven by a bevel-gear 65 on the shaft 28 and the other by the bevel-gear 29, herein- For the purpose of varying the twist the gears 61 62may be removed and others substituted for them.

The spools which are employed are indicated at 70, being, in effect, cylindrical bobbins flanged at their upper and lower ends.

From the foregoing it will be observed that the two strands or rovings are passed from a lower reel and one immediately above it between a pair of rolls and through a yarnguide 60 to the traveler 36 on one of the rings.

Moreover, the skein-holding reels are so mounted one above another that the yarn from the upper one passes close to the periphery of the lower one and both yarns pass to the rolls of the spinning apparatus in juxtaposition or parallel with and close to each other, thus avoiding any bends in either yarn or change in the direction of movement thereof that would tend to break the strands of which the skeins are composed. In other Words, the delivering sides or peripheries of both reels (those portions from which the yarns lead or are drawn) are in substantially the same line or direction above the rolls 55 59, so that said yarns both pass directly to saidrolls without 5 lateral deflection.

In operation the machine accomplishes the doubling, twisting, and spooliug of the yarn in a single operation. The frame itself is simple, the various parts being driven from, the shaft 16 with a minimum number of gears.

Having thus explained the nature of the invention and described a way of constructing and using the same, although withoutattempting to set forth all of the forms in which it may be made or all of the modes of its use, I declare that what I claim is- 1 A machine for doubling and twisting yarns from the skein, comprising a spindle, a ring and traveler, supplying-rolls, and skeinholding reels arranged one above the other and above the spindle, the delivering sides of both reels being in substantially the same line or direction from the said rolls.

2. In a machine of the character described, means for supporting skein-holding reels one above the other, rolls for supplying the yarn from the reel, said rolls being located substantially in the direction of a straight line from the delivering sides of both reels, a spindle adapted to support a spool thereon below the rolls, and a ring and traveler, substantially as described.

3. A machine for doubling and twisting yarns from skeins, comprising a spindle, a ring and traveler, supplying-rolls, and skeinholding reels arranged one above the other and above the spindle, the upper reel being adjustable relatively to the lower one, the delivering sides of both reels being in substantialllly the same line or direction from the said ro s.

4:. A machine for doubling and twisting yarns, comprising standards each having a plurality of forwardly and rearwardly projecting arms arranged one above the other, the upper arms being adjustable, skein-holding reels supported by said arms, and means for twisting the yarns supplied by said reels, said means being located substantially in the direction of a straight line from the delivering sides of both reels.

In testimony whereof I have affixed my signature in presence of two witnesses.

BENAJAH S. ALLEN.
