MACHINE FOR WINDING YARN FROM CHAINS ONTO FILLING-BOBBINS.

SPECIFICATION forming part of Letters Patent No. 416,495, dated December 3, 1889.

' Application filed September 1,1888. S....'.1N..28l,330. (No model.)

To all whom it may concern.-

Be it known that We, HERBERT L. PRATT, of Lewiston, in the county of Androscoggin and State of Maine, and CHARLES T. UPTON, of Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Machines for WVindin g Yarn from Chains onto Filling- Bobbins, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to machines for windin g yarn from the chain directly onto the filling-bobbins for use in shuttles for weaving.

Heretofore filling-yarn after it has been dyed or bleached in the skein was placed on. reels, from which it was spooled and was then wound from the spools onto the fillingbobbins or cops, or the dyed skeins of yarn were wound onto a beam, from whence the yarn was Wound onto the filling bobbins or cops. In each of these enumerated methods there are found inherent defects which render the respective methods objectionable. It is undesirable to wind the yarn skeins first on reels and then on the filling bobbins or' cops, in consequence of the frequent breakage of the yarn in unreeling, whereby the method is made expensive, and in. consequence of the irregular delivery by the reels of the yarna defective cop-nose is produced. Again, it is desirable not to increase and complicate the manipulations of the filling-yarn in the preparatory method by the employment of the spooling or beaming step previous to winding the yarn onto the filling bobbins or cops, since such an extra step tends to injure the dyed or bleached yarn, and, moreover, prolongs the operation and accordingly increases the cost of preparing the filling bobbins or cops for weaving.

One object of our invention is to provide a machine for winding the filling-yarn directly from the chains on filling bobbins or cops for use in the loom-shuttle.

Another object of our invention is to provide a machine for winding the filling-yarn on the filling bobbins, quills, or cops that will produce a good cop-nose on the bobbins, cops, or quills, so as to prevent the Waste of yarn and the stoppage of the loom caused by the uneven laying of the yarn on the cops or quills and the imperfect formation of the cop-nose.

T o the above purposes our invention consists in the peculiar and novel construction of the machine by which yarn fromthe loose or balled chain is wound directly on the filling bobbins, quills, or cops for direct introduction to the loom-shuttle for weaving.

In the drawings, Figure 1 is an end view of our improved machine. Fig. 2 is a sectional view of our improved machine, the mechan ism for driving the spindles being shown in broken lines. machine.

In the drawings like numbers of reference designate corresponding parts throughout.

Referring to the drawings, it will be seen that the machine is provided with eight lines of spindles secured to bolster-rails extending from one end to the opposite end of the machine and placed so that the second bolsterrail is behind the first and above the same, and all the other bolster-rails (whether four, six, eight, or more are used) are each placed in the rear of the rail in front and above the same, so that the spindles form an inclined bank or slope, each one of which can be readily reached by the attendant for the purpose of doffing or piecing.

The numbers 1 designate the ends of the machine which form the supports to which the bolster-rails 2 2 are secured and also the supports for the driving-cylinders and the mechanism by which the various parts of the machine are operated. The bo1ster-rails 2 each support a line of spindles. In Fig. 2 only twO Spindles are shown as secured to each bolster-rail; but in the machine as used the'spindles are placed along nearly the whole length of the bolster-rail as close together as the practical working will permit.

The numbers 3 represent the spindles, each of which is provided with a whirl to receive the driving-band.

Numbers 4: designate the'bobbins or quills Fig. 3 is a front view of the on which the yarn is wound in the shape of a cop ready for use in the loom-shuttle.

5 designates the driving-cylinders turning in the bearings 6 in the ends 1 of the machine. Each one of the cylinders 6 is made to operate two lines of spindles. The bands 7 7 pass partly around the driving-cylinders 5 and the whirls of the spindles 4, so that for a machine with eight lines of spindles four driving-cylinders are used. I

The machine is driven by means of a belt communicating power from a prime motor to the pulleys 8 9, 8 being a pulley secured to the driving-shaft, and 9 a pulley loose on the shaft. The power is transmitted from the fixed pulley 8 by means of the gears 10 and and 11 to the main driving-cylinder 5. On the opposite. end of this main driving-cylinder 5 the gears 12 transmit the power to the other driving-cylinders 5, so that all the driving-cylinders, and, by means of the drivingbands 7, all the spindles, revolve with the same speed. To the projecting end of the shaft of main driving-cylinder 5 the chaingear 13 is secured, and from the same the chain 14 passes over the chain-gear 15, secured to the shaft of the roll 18, from which, by means of the gears 17, motion is transmitted to the roll 16. The top roll 19 rests on the two rolls 16 and 18 and turns with them. This top roll 19 is covered with rubber or similar elastic material to secure a firm bearing at all points on the surface of the rolls 16 and 18. On the top of the machine, in the rear of the rolls 16, 18, and 19, is secured the reed 20, and farther back the guide-roller 21. To the projecting end of the shaft of the lowest driving-cylinder 5 the chain-gear 22 is secured, the chain 23 passing from the chain-gear 22 to the chain-gear 24, from which motion is imparted by means of gearing to the cop-forming mechanism 25, by which the reciprocating guide-wires 26 are operated. These guide-wires are secured to the horizontal rods 27, extending from end to end, and are supported on the inclined frame 28, which is in turn secured to the upright supports 29, the feet of which rest on the levers 30, which levers are provided with the balance-weights 31, by which the cop-building guide-wires, the horizontal rods, and the frame in which the rods are carried, as well as the upright supports 29, can be counterbalanced or slightly overbalanced, so that the cop-building mechanism can operate the same with the least practical strain. The counterbalanced levers 30 are placed near each end of the machine and are connected, so as to be operated together by the cop-building mechanism, as is shown clearly in Fig. 3.

The cop-building mechanism consists of the cam 40, revolved by means of the shaft carrying the chain-gear 24 and intermediate gears 49 and 50. (Shown in Fig. 2.) The edge of the cam 40 bears against a stud 51, projecting connected with the arm 44, mounted on the lever 30.

The cam 40 in the cop-building mechanism shown in the drawings is a circular disk secured to the shaft at one side of the center, so as to impart in revolving reciprocating motion to the horizontal lever 41, which motion is transmitted by the strap 43, secured to the pulley 42, to the levers 30, and by the said levers to the inclined frame 28, upright supports 29, and rods 27, carrying the guide-wires, which are reciprocated vertically to guide the yarn on the conical base of the bobbin, thus laying one layer of yarn as the horizontal lever 41, operated by the cam 40, moves upward and another as it moves downward, the weight of these reciprocating parts being counterbalanced or nearly counterbalanced by the weights 31.

To build the sides of the cop of uniform diameter while preserving the conical upper end, a take-up motion is connected with the pulley 42, consisting of a worm 52, turning in bearings secured to the horizontal lever 41, which gears into the worm-gear 45, secured to the pulley 42, to which the strap 43 is secured. The outer end of the shaft of the worm is provided with the ratchet-wheel 46 and the lever 48, loosely turning on the shaft, one end of which lever is provided with a pawl and the other end is connected with the stop rod 47, having two stops, as is clearly shown in Fig. 3. Near the end of the upward motion of the reciprocating end of the horizontal lever 41, as well as near the end of the downward motion, the stops on the stop-rod 47 operate the lever 48 by contact with the L-shaped arm 53, through a slot in which the stop-rod 47 passes, and by means of the pawl and ratchet-wheel partially turn the worm, and by it the worm-gear 45, secured to the pulley 42, and wind a portion of the strap on the same, thus permanently raising the guidewires at each reciprocation sufficiently to lay the successive cones of yarn until the bobbins are filled.

We do not wish to confine ourselves to the cop-forming mechanism herein shown and described, as any kind of cop-forming mechanism may be used.

These machines are usually built of greater length than the proportional length shown in Fig. 3, and as six, eight, or more lines of spindles are banked above and behind each other a very large number of spindles may be used and easily overlooked by the operative.

The machine is started and stopped by shipping the driving-belt to or from the drivingpulley by the shipper 32,which is connected by IIO means of the bell-crank 33 with the rockshaft 34, to which the levers 35 are securely fastened and provided at their end in front of and extending the whole or nearly the whole mechanical parts already described.

The dyed or bleached yarn in the chain is placed on the floor in the rear of the machine, and one end of each skein is passed over the guide-roller 21 and through the reed 20. Each thread is now passed over the rolls 18 and 16 (the top roll 19 being removed) and through one of the guide-wires 26 to one of the spindles. The different threads extend in diverging lines from the delivery-roll 16, the front of which is on or nearly on a line with the front and lowest row of spindles, to the several rows of spindles, as is shown in Fig. 2. By this arrangement every thread between the delivery-roll and the guide-eyes is within reach of the attendant, and if broken can be pieced up without stopping the machine. When all the threads of yarn have thus been connected with the spindles, the top roll 19 is placed on the delivery-rolls l6 and 18, holding every thread firmly to the delivery-rolls, and

thereby securing a uniform delivery of the yarn to all the spindles and a uniform tension on the yarn. This uniform tension enables us to form a perfect nose to the cop, which will not strip in the shuttle and cause Waste of yarn as well as loss in the product by the necessary stoppage of the loom. This most important advantage is secured partly by the the yarn uniform, and partly by drawing theyarn by means of the rollers 16, 18, and 19 directly from the hank orchain, by which a more uniform tension and delivery is secured than can be secured when the yarn is drawn or delivered from a reel or beam.

The elasticity of the yarn under a strainis considerable, and when the strain is reduced the nose of a bobbin, cop, or quill, on which the yarn has been laid while strained, will be ruined by-the yarn entering the previouslywound nose of yarn by contraction, and thus ruining the cop for use in the shuttle, or at least causing waste and stoppage by the stripping of the nose.

\Vhen all the yarns from the chains to be wound have each been secured to the quills or bobbins on the spindles of the machine, the same is started by raising the board 36 on the ends of the levers 35. The operative has full delivery-roll facing the operative.

and clear View of all the spindles and the threads of yarn, he can easily and quickly reach any thread while the machine is in operation, and can quickly stop the machineby depressing the board 36, and thus throw-' ing the belt on the loose pulley.

In a machine for winding yarn having a bank of spindles consisting of a number of rows of spindles, one above and behind-the other, it is essential to the practical working of the machine that the delivery roll or rolls can be easily reached by the operative. The said rolls must be so located that the length of yarn between the delivery-rolls and the guide-eyes on all the lines of spindles can be easily reached by the operative to facilitate piecing up, and all the yarn for all the spindles must be delivered from the sides of the To accomplish all this we project the side frames and place the rolls 16, 18, and 19 so far forward that the face of the delivery-roll 16 is nearly on a line with the front line of spindles and all the yarn within reach of the operative.
