AUTOMATIC SPOOLINGr-IVIACHINE.

Specification of Letters Patent.

` Application filed June 16, 1911.

Patented Feb. 20, 1912. seriai No. 633,521. i

To all whom it may concern:

'Be it known that I, ALEXANDER GROUND- wA'rnR IVALLS, a subject of the King of the United Kingdom of Great Britain and Ireland, and residing at Paisley, Renfrewshire, Scotland, have invented a certain new and useful Improvement in Automatic Spooling-Machines, of'which the following is a specification.

This invention relates to automatic spooling machines having the spooling heads and the cam motions similar to or resembling more or less, those of the IVeild type shown in U. S. Patent No. 51907, granted to lVilliam Weild, and citations therein, and also in British Patents Nos. 1128 of April 16, 1867 and 48 of January 6,1870 also granted to William Weild.

According to the invention, there are provided two or more parallel rows of spooling headstocks fitted with spindle, gear, thread cutting and holding, nick-cutting and spool-feeding mechanism similar to those on well known types of Weild spoolfA ing machines having the usual single row of spooling heads. The various motions on the parallel rows of spooling headstocks are coupled together so that all work in unison. In order that the parallel rows of spooling heads may perform their operation simultaneously the right angle motions are coupled to the various shafts, at or very near, the same point in the shafts, so that torsional error in the shafts maybe avoided.

Figure I is a sectional end elevation of a machine of t-he type referred to equipped with the improvements. Fig. II is a front elevation. Fig. III is a front elevation and Fig. IV is a sectional end elevation showing details of the traverse mechanism. Fig. V is a rear elevation and Fig. VI is a diagrammatic sectional end elevation of the main headstock of the machine.

Referring particularly to Fig. I of the drawings, the machine comprises the usual rail l of channel section for supporting the spooling heads, and a similar rail 2 for supporting a second row of heads, each rail being fitted with the usual complemental parts such as the spooling heads 3 and 4; the brackets 5 and 6 for carrying the nickin'g, cutting and holding mechanism which includes the nicking knives 7 and 8, and the usual thread hook holding spring and cutting knife of the Weild ,ending motion as at 9 and 10. Shafts 11 and 12 carry the tail centers or short spindles and shafts 13 and 14 control t-he endwise motion of the driving spindles. 15 and 16 -are the thread wire shafts. 17 and 18 are the side or starting end knife shafts. 19 and 20 are the spindle wheel shafts. 21 and 22 are the thread hook shafts. 23 and 24 are the traverse shafts and 25 and 26'are the spool lifter shafts.

The odd reference numerals, 1 to 25, Fig. I, indicate well known parts of the lVeild type of spooling machine, and the even reference numerals, 2 to 26, Fig. I, indicate the same parts in the second row of spooling heads.

The following means are provided for coupling the motions of the parallel rows'of spooling heads in so far as they are shown in Fig. I. 27 is the usual longitudinal cam shaft of the Weild type of spooling machines. 28 is the nieking shaft, which shaft is rocked in the usual way by means of a cam and lever. The nicking knives 7 and 8 receive 'their movement through the couplings and levers 29, 31 and 30, 32, respectively. The thread hook shaft 21 'receives movement from 'its corresponding lcam through the intermediary of a bell-crank cam lever 33, coupling 34 and lever 35. The thread hook 9 is then actuated by means of a lever'36. A lever 37 is fixed to the thread hook shaft 21, and movement is communicated to a similar lever '38 on the thread hook shaft 22 by means of a coupling link 39. The thread hook shafts 21 and 22 therefore work in unison and as the lever 37 is vsecured to the shaft 21 at a point near to the point of connection of said shaft 21 with its corresponding cam by the lever 35,- there is no appreciable torsional difference in the said shafts 21 and 22.

40v is the cam lever for controlling the spool lifter's. Movement'is imparted 'to thespool lifting shaft 25 by means of a coupling link 41 and a lever 42, which lever is mounted freely on the shaft'25 but is coupled by means of a spring 43 to a lever 44 which is secured to the spool lifting shaft 25. The spool lifter 45 is actuated by means of alever 46 and is carried upward and forward over a roller 47 on the bracket 5. Movement is imparted from the shaft 25 to t-he spool lifter shaft 26 by means of a lever 48, link 49 and a lever 50. The spool'lifter shafts 25 land 26 therefore Work in unison and as the lever 48 is secured to the-shaft 25 in a position near to the point of connection to the corresponding cam (not shown), there is no appreciable torsional difference in the shafts l25 and 26.

The traverse shafts 23 and 24 carry the guide stocks and guides for laying the thread on the spools, In order to minimize torsional error produced in rocking said shafts to lift the guides, the traverse shaft 23 is of large diameter and has its torsion applied at two widely separated points by means of levers 51 keyed on the shaft 23 and on the torsion distributing 'shaft 52, which, together with the levers 51, receives movement, the shaft 23 serving as a fulcrum, from a lever 53 disposed between the levers 51.

'Io communicate torsional movement from the traverse shaft 23 to the traverse shaft 24 there are mounted two levers 54 in juxtaposition to the levers 51 on shaft 23. By means of links 55 and levers 56 movement is imparted to the traverse shaft 24 from the levers 54, and as the levers 54 are mounted on the traverse shaft 23 at widely separated points, the torsion is distributed on the shaft 24 by the equally spaced levers 56. 'Io eliminate play in the joints of the links and levers 54, 55 and 56, a spring 57 is connected to each pair of levers 54 and 56. The traverse shafts 23 and 24 therefore work in unison and as power is introduced to both shafts at nearly the same point in their length there is no appreciable diHerence in torsion in the two shafts 23 and 24.

As shown particularly in Fig. II the cams for imparting endwise movement to the spindle controlling shafts 11, 13 and 12 and 14, and the thread wire shafts 15 and 16, are mounted on cross cam shafts 60 of the machine, which shaft 60 is driven in the usual way by bevel gearing from the longitudinal cam shaft 27. On the shaft 60 are mounted six cams, in lieu of three cams, as heretofore. The two innermost cams acting through the intermediary of levers 61 and 62 pivoted at 63 actuate the spindle controlling shafts 12 and 14 of the spooling heads on the rail 2. The next (or third) cam on the shaft 60 imparts movement to a lever 64 which is pivoted at 65. The lever 64 actuates, by means of a link 66 and joint 67 the thread wire shaft 16 of the spooling heads on the rail 2. The cams next in order (the fourth and fifth cams) on said shaft 60 actuate, respectively, by means of levers 68 and 69 pivoted at 70, the spindle controlling shafts 11 and 13 of the spooling heads on the rail 1. The outermost (or sixth) cam on said shaft 60 imparts movement to a lever 71 which is pivoted at 72. The lever 71 actuates, by means of a link 73 and joint 74, the thread wire shaft 15 of the spooling heads on the rail 1. The spindle controlling shafts 11, 13

and 12, 14, work in unison, as all of the six cams above mentioned are secured to the cam shaft 60, and "fas the levers 61 and 62 are proportionate to the levers 68 and 69, while the first, second, fourth and fth cams, in the order above mentioned are constructed similarly and are adapted to be adjusted to their respective levers so that the movements of the levers synchronize. The usual shaping cam 75 of the machine carries a hand wheel 7 6. As is usual in spooling machines of the VVeild type, the said hand wheel is fixed on the shaft 75 and carries on its boss a small cam for operating the shafts 17 and 18 which carry the side or starting end knives. A lever 77, pivoted at 78, bears against the side knife cam, which cam is located behind the hand wheel 76. rIhe lever 77 operates, by meansof a link 79, one arm of a bell-crank lever 80 mounted on the shaft 81 which passes through the rail 1 and which carries at its outer end a lever 82 which lever bears against and actuates, the side knife shafts 17 of the spooling heads on the rail 1. The other arm of said bell-crank lever 80 actuates, by means of a link 83, one arm of another bell-crank lever 84 pivoted on a stud on the rail 2. The other arm of the bellcrank lever 84 bears against, and actuates, the side knife shaft 18 of the spooling heads on the rail 2; the shafts 17 and 18 being thus caused to work in unison.

The traverse shafts 23 and 24 of the spooling heads on the rails 1 and 2, respectively, are shown in Fig. II, also a rectangular bracket 85 hereinafter called the guide shaft coupling, and a frame 86 carrying the usual traverse screw 87 of the Veild type of spooling machine, but for the sake of clearness, the arrangement of traverse (or guide) shafts, guide shaft coupling and traverse screw as shown particularly in Figs. III and IV. The bracket 85 forming the guide shaft coupling is rectangular in shape but is curved rearward as shown in Fig. IV. The usual square frame 86 of the lVeild spooling machine for carrying the usual right or left hand guide screw and shortl traverse shaft 88 is mounted in such a position that the axis of the said shaft 881s, as nearly as possible, equi-distant from the axis of the traverse shafts 23 and 24. The traverse shafts 23 and 24 are free to rotate in their bearings in the guide shaft coupling 85 but are controlled as to endwise movement by means of stop collars 89 and 90 and thrust adjustment nuts 91, 91a. The bearings of the shafts 23 and 24 in the coupling 85 are made long, and end play on each individual shaft may be eliminated by adjustment of lock nuts 91 and 91a, thereby in-sur-` ing that the shafts will work in unison, in so far as their sliding or endwise movement is concerned.

The end of the. shaft 88 -is screw-threaded and in the center of the coupling 85 there is mounted a bracket 92 having an orifice provided with a female thread to lit the screwthreaded endof the shaft 88. The femalethreaded portion is mounted on the coupling 85 co-axially with the shaft 88 which is screwed into a correspondingly threaded orice in a bracket 92 and adjustably fixed by a lock nut. A rocking bracket 93 adapted to carry the usual half-nuts, one on either side, for engaging with the right or left hand screw-threaded portions of the guide screw, is held on the shaft 88 by means of the usual stop-collars 91, 95. The usual to and fro traverse motion of the lVeild spooling machine isimparted by means of the shaft 88 to the guide shaft coupling 85 which carries the two traverse (or guide) shafts 23 and 241, which shafts are therefore caused to slide in unison.

Referring particularly to Figs. V and VI, the machine is driven by an electromotor secured to a stretcher 96 located near the base of the machine frame. A shaft 97 which is driven by means of a flexible coupling and forms a continuation of the motor shaft, is carried in the main headstock of the machine. On the shaft 97 is mounted a coil clutch of which one member 98 is free to move endwise but rotates with the shaft. rI`he other member 99 of said clutch is mounted freely on the shaft 97 and carries a gear wheel 100 which, by means of an inv termediate gear wheel 101, drives a gear wheel 102 secured to a shaft 103 hereinafter called the first motion shaft. In operation the motor is permit-ted to run continuously, and by means of suitable lever devices the sliding clutch member 98 is brought into contact with the other clutch member 99 which carries the gear wheel 100 and thereby imparts movement to the other gear wheels and relative connections. lVhile the clutch members 98 and 99 are in positive engagement with each other, the rst motion shaft 103 runs continuously, whether the machine is spooling or ending. On the first motion shaft 103 are mounted two coil clutches having one common sliding member 1.01 which is free to slide endwise on, and rotate with the shaft 103. On the first motion shaft, between the sliding clutch member 104 and the gear wheel 102, there is mounted a free clutch member 105 which carries a gear wheel 106 serving to drive the spooling motions of the machine and hereinafter called the great wheel. On the said clutch member 105 is mounted a brake pulley 107 which checks the momentum of the spooling motions. When the sliding clutch member 101 is brought into positive engagement with the free member 105 the great wheel 106 is caused to rotate; in suitable positions are mounted two intermediate wheels 108 and 109. The intermediate wheel 108 serves to drive a wheel 110 mounted on a short shaft 111, Figs. III, IV and VI, adapted to rotate in the usual square frame 86 of the lVeild spooling machine. For the sake of clearness in the description, the shaft 111 is hereinafter referred to as the spindle` wheel shaft extension, because it rotates at the same speed as the spindle wheel shafts 19 and 20, and carries on its outer end the usual pinion for driving the spooling change gears. In addition to driving the gear wheel 110, the said intermediate gear wheel 108 drives a gear wheel 112, the number of teeth of which correspond to the number of teeth in the gear wheel 110, said gear wheel 112 being mounted on the spindle wheel shaft 19 of the bottom row of spooling heads. In a similar manner the intermediate gear wheel 109 drives a gear wheel 113 mounted on the spindle shaft of the top row of spooling heads and having teeth corresponding in number to the number of teeth in the gear Wheel 110. The gear wheels 110, 112 and 113 have all the same number of teeth and are driven by means of intermediate gear wheels from one common driving wheel-the great wheel 10G-and are mounted, respectively, on the spindle wheel shaft extension 111, on the spindle wheel shaft 19, and on the spindle wheel shaft 20. Therefore, the spindle wheel shafts in both rows of spooling heads and the spindle wheel shaft extension carrying the usual spooling change gear driving pinion, are driven synchronously.

In order to drive the ending motions of the machine, there is mounted on the first shaft 103, a three-coil clutch member 114, hereinafter referred to as the ending motion clutch, and the sliding clutch member 104: is brought into positive engagement with the ending motion clutch 114, to cause/said clutch to rotate. On the ending motion clutch 1141, a pinion 115, Fig. V, lis mounted, which pinion 115 drives, by means of an intermediate gear wheel 116, a gear wheel 117 mounted on a short shaft 118 passing through the side of the machine frame, and thus transmitting power outside the main headstock. On the outer end of the shaft 118 a pinion 120 is mounted. The pinion 120 acting through the usual reducing gear, consisting of a gear wheel 125 mounted on one end of an intermediate shaft 126 carrying at its other end a pinion, drives the gear wheel 127 Fig. II, mounted on the longitudinal cam shaft 27, carrying the ending motion cams, i

Having now described my invention what I claim and desire to secure by Letters Patent of the United States is 1. In an automatic spooling machine, the combination of a plurality of rows of headstocks, nicking, cutting, holding and winding mechanisms carried by said headstocks,

and mechanisms for actuating said niclring, cutting, holding and Winding mechanisms, said actuating mechanisms being coupled together to causeall said spooling means to operate in unison.

2. In an automatic spooling machine, the combination of a plurality of rows of headstocks, spooling means comprising winding, nicking, cutt-ing and holding mechanisms, carried by said headstocks, ending means associated with said headstocks, means for actuating said spooling mechanisms, said means being coupled together to cause them to operate in unison, and means coupling said ending means to cause the same to operate synchronously.

3. In an automatic spooling machine, the combination of a plurality of rowsof headstocks, spooling means on each headstock comprising winding, cutting, nicking and holding means and including shafts parallel to said rows for supporting said winding,

cutting, nicking and holding means, means for actuating said shafts and means coupling the actuating means of each set of 2b corresponding shafts in each headstock to 35 cause the latter to operate in unison.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
