COP-WINDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 772,603, dated October 18, 1904.

7 Application filed January 19, 1908. Serial No. 139,576. (No model.)

To all whom it may concern:

Be it known that we, J OHN H. BENTLEY and WILLIAM GREGORY, citizens of the United States, residing at Paterson, in the county of Passaic and State of New J ersey, have invented certain new and useful Improvements in Cop-Winding Machines, of which the follow I mechanism for starting the spindle in its upward movement at the'beginning of the formation of the cop. While our machine applies to cop-winding generally, it is especially designed for winding a hollow cylindrical cop with a rounded or somewhat-conical nose and base, from which in use the thread can be drawn either from the interior or exterior,

but preferably from the interior.

The object of our invention is to provide a machine that will produce atubeless cop adapted for use in shuttles for weaving purposes and which will so wind the cop as to permit the thread to be delivered from either the interior or exterior of the cop with evenness and regularity when it is carried through the shed by the shuttle in the process of weaving.

The further object of our invention is to provide such a machine with a loosely-mounted cup or thimble to surround that portion of the spindle whereon the cop is formed and having a hollow conical-shaped interior.

A further object of our invention is to provide in such a machine means to start the spindle in its vertical movement at the time that the cop is beginning to be formed; and a further object of our invention is to provide the clutching mechanism with an adjustable friction device thatwill causethe spindle to revolve gradually for a period before themain clutching devices are engaged to rotate the spindle at itsusual speed; and a still further object of our invention is to provide automatic means for disengaging the clutch devices to stop the :spindle automatically upon the breakingof a threadand for withdrawing the spindle from the cop when it is finished.

In theaccompanying drawings like characters of reference indicate like parts.

Figure 1 is an end 'view of a portion of a machine embodying our improvements. 2 is a side elevation of same, showing our compound clutch device in section. Fig. 3 is a plan view of a portion of a machine, showing a method of imparting a vertical movement to the spindle from the main shaft. Fig. 4 is a section through our cop-forming cup, showing the method of loosely mounting the same in the upper table of the machine. Fig. 5

shows detail views of the automatic spindleelevating device, both in section and in elevation, the section being on the line 2 z, the device being out of operative engagement. Fig. 6 shows detail views the same as Fig. 5, with the exception that the swinging pawl and ratchet of the spindle-elevating device are in operative engagement. Fig. 7 is a view similar to Fig. 1, but enlarged, and showing a mechanism for driving the spindles and Fig. 8 is a plan view of one set of four spindles, showing the mechanism for driving the same.

The operating mechanism connecting the shaft 1 with the gearing 31 consists of a mitergear a, which is secured to said shaft 1 and meshes with a miter-gear b, which is secured with the gearing 31. The shaft 6 is mounted Fig.

in the support or bearingd, and to the shaft c is secured the spur-gear c and the mitergear 6. The bearing d is secured to the frame 26. The spur-gears 31 are secured to the spindles 11, which are operated from the main shaft 1 through the above-described operative connections.

Power is communicated to the main driving-shaft 1.0f the machine by belt or pulley or in any other suitable manner. A worm 2 is secured to the shaft 1 and engages a wormgear 3, secured on shaft 4:, which is mounted at right angles to the main shaft.

end of the shaft 4 are secured worms 5, which engage and turn worm-gears 6, secured to the On each shafts 7 7 which are mounted parallel to each other on either side of the machine and at right angles to the shaft 1.

On the shafts? 7 are secured ratchet-wheels 8, one for each spindle on the machine, and these ratchets 8, turning with the shafts '7, are adapted to engage the swinging pawls 13 when said pawls are swung in the direction of the ratchet by the arm 10, which is secured to the connecting-rod 9 upon the up ward movement of the said rod.

The swinging pawl 13 is suitably mounted in the fixed bracket 12, secured to the spindle 11. As illustrated in Figs. 5 and 6, the turning of the ratchet in engagement with the swinging pawl 13 causes the spindle to rise until the pawl 13 has been carried to a point beyond the engagement of the ratchet. This elevating of the spindles by means of the ratchet 8 and swinging pawl 13 is gradual and continuous while it lasts and takes place at the beginning of the formation of the cop, as it will hereinafter more fully appear, and prevents the bunching of the thread, which is otherwise liable to occur, and by providing for the distribution of the thread on the rising spindleinsuresagood foundation for the commencement of the cop-building process.

The bracket 12, which is secured to the spindle 11 and in which the swinging pawl 13 is mounted, has a forked end passing on either side of the connecting-rod 9, and from the top of the bracket 12 passes a chain or cord 14, one end of which is secured to said bracket 12, and thence over a sheave or roller 15, which is secured to said connecting-rod 9, and a weight 16 is secured to the other end of said chain or cord. On the upper table 17 of the machine is secured a tilting block 19 on a base 18.

The tilting block is provided with a handle 19 and the usual arm 20.

The tilting block 19 is pivotally secured to the stand 18, and the connecting-rod 9 is pivotally connected with the rear upper portion of the tilting block 19, as is indicated by 21. WVhen the tilting block 19 is tipped back, as indicated to the right in Fig. 2, the connecting-rod 9 is lowered and our compound clutch device is disengaged, so that the spindle 11 is not rotated; but when the tilting block 19 is down and forward, as is indicated to the left in Fig. 2, the connecting-rod .9 is drawn up in Fig. 2, when the cop is finished and the tilting block 19 is tipped back, disengaging the clutch mechanism and stopping the operation of the spindle.

Owing to the point of connection of the rod 9 and the tilting block 19 the pressure of the friction-cone 59 of the rising spindlel 1 against the friction-cone 58 on the rod 9 causes the tilting block 19 to be tipped back, as shown on the right in upper portion of Fig. 2, and the weight 16 aids in the tipping of the tilting block and the drawing down of the rod 9.

The mere engagement of the friction-cone 59 with the friction-cone 58 is in itself suilicient to accomplish the tipping of the tilting block, and the weight 16 may or may not be used. Said cup 22 is provided with a vertical slot 8 in one side thereof and on two sides with a recess, into which recesses 2a the arms of the plate 23 are adapted to it loosely. The opening in the plate 23 is the shape of a horseshoe, and the plate itself is secured to the stand 18. The cup is capable of a slight motion or movement in any direction and is held in place in the plate 23 by the spindle 11, which passes therethrough.

It is not deemed necessary in this application to show how the cop is formed by the traverse of a vibrating distributing device which conveys the thread up and down through the said slot .v as the thread is being wound upon the spindle 11.

The cup 22, as shown in Fig. 4, has an opening therethrough to receive the upper end of the spindle 11. The upper portion 55 of said opening is larger than the opening in the lower portion of the cup. The opening in the lowerportion is cone-shaped, and the opening in the upper portion is bell-shaped, as shown in Fig. 4, and where the bell-shaped portion meets the lower cone-shaped portion 56 an annular ridge 57 is formed, which is smaller in circumference than any other portion of the opening through the cup, but which allows to a certain extent for any vibration of the spindle. This movability of the cup aids in the formation of the cop and allows for a more perfect adjustability of the cup to the cop during the winding process, and the rounded conicalshaped shoulder 25 makes the movement of the cup 22 free. On the lower su morting-table 26 of our machine is secured the rail 27, which carries our auxiliary clutch and which is provided with the cylindrical sleeve 27. A sleeve 28, having an annular flange 29 at its lower end, is secured in the sleeve 27 and through said inner sleeve 28 the spindle 11 passes and turns. Between the inner sleeve 28 and the outer sleeve 27 is a loose sleeve 30, adapted to be rotated around the inner fixed sleeve 28 above the annular flange 29. Said intermediate sleeve 30 has secured to it a gear 31, which is driven from the main shaft 1. On

the lower portion of the loose sleeve 30 and integral therewith is a hollow cylindrical portion 32, having on its inner side two oppositely-located lugs 33, which forms a portion of our compound clutch. i

The lower portion of our clutch consists of the plate 3 1, having an extended hub with a central opening therethrough provided with a feather or key adapted to slide in a key-seat or longitudinal slot in the spindle which passes through the central opening in the plate 34;, as indicated at 36 in Fig. 2. On the "upper surface of the plate 3 1 are two lugs or jaws 35, adapted to engage the corresponding lugs 33 in the upper clutch member.- The spindle 11 projects below the bottom of the clutch member 34 and through an opening in the arm 37, which is secured to the lower end of the connecting-rod 9, so that'when the tilting block 19 is tripped and falls back, as is shown to the right in Fig.2, the connectingrod 9 is lowered, the lower clutch member drops out of engagement with the upper clutch member and rests on a lever;arm' 37, through which the spindle 11 passes.

I reverse is the case when the tilting block is Saidspring-band extends a distance above" member is rotated.

' too great a strain upon the mechanism and upon the threads. We therefore-employ an auxiliary clutch member to start the spindle in its rotary movement at the time the cop is begining to'be formed and for a short'period before the lugs of the upper and lower clutch members are engaged, which will rotate the spindle at a lower speed, and thus avoid the breaking of the thread. This auxiliary clutch member consists ofthe adjustable spring-band 38, which is secured to an annular shou'lderon the clutch member 34 on pins which pass into longitudinal openings 10 in the said bands, the ends of said band being adapted to be drawn together by the tightening and loosening device 39 to regulate the friction or grip of the band on and around the outer surface of the hollow cylindrical portion 32 of the sleeve 30.

the lugs 35 on the clutch member 34,and by virtue thereof the friction of the spring-band,- with the sleeve 30, turns the lower clutch member 34: until the

lugs

33 and 35 become engaged, so that the formation of the cop has been well begun before the spindle is rotated at full'speed.

VV'e employ a hand-operated device which is connected with the spindle for the purpose 11 is secured a friction-cone 59.

The

'of doffing the cop. By pressing on the handlever of the device the spindle is forced downwardly out of the cop when the cop is completed, and the thread first wound around the spindle at thecommencement of the formation of the cop is the delivery end of the thread when the cop is placed in the shuttle for weaving purposes. It is thus obvious that the thread is delivered from the interior of the cop. On the connecting-rod 9 is secured a friction-cone 58, and on'the spindle When the cop is completely formed on the spindle 11 in the cup 22, the spindle 11 is elevated to such an extent that the friction-cone 59 engages the friction-cone 58 on the rod 9,

and the lateral pressure thus produced trips the tilting block 19, thus lowering the rod 9 and the clutch-support connected to the lower end thereof, disengaging the clutch, and stopping the rotation of the spindle '11. (See right-hand portion of Fig. 2 in the drawings.)
