WIN DING-MACHINE.

Specification of Letters Patent.

Patented Jan. 5, 1909.

T o all whom 'it 'may concern:

Be it known that I, PIERRE VINDRIER, a citizen of the French Republic, residing at Lyon, in the French Republic, have invented certain new and useful Improvements in Winding-Machines, of which the following is a specification.

The improvements in winding machines which form the object of the present invention have for their purpose to allow of obtaining tightly cross-wound cops which do not become unwound by the eifects of the impacts of the shuttle, and the invention also has the advantage of considerably increasing the amount of thread in a cop of given size. These results are obtained by substituting for the ordinary thread-guides a roller which continuously rubs against the cop to be produced, whatever may be its size, this roller having formed around it an oblique groove destined to impart to the thread, by the rotation of the roller, a very rapid reciprocating movement combined with the movements common to other winding machines.

The annexed drawing shows in Figure 1 an elevation and in Fig. 2 a plan-view of an element comprising a thread-guide and spindle. Fig. 3 is a detail view of a modification of the roller. Figs. 4 and 5 are respectively a plan and side view of the mechanism for imparting movement to the yarn guide. Fig. 6 shows a dtail of mechanism for varying the speed of the movements imparted to the yarn guide.

Each element comprises a guide-support A fixed by a bolt and nut B to a common bar O extending all along the machine and fixed at its two ends to a slide D having a double vertical movement, namely a continuous slow movement from bottom to top and a reciprocating movement of greater or less amplitude. Both these are obtained by the ordinary known means and are suiliciently indicated by the three arrows upon the slide D in Fig. 1.

The guide-support A is traversed with slight friction by a bar E bent at one end at E1 and soldered at the other to a socket F on which turns a roller Gr having on its circumference an oblique groove I-I, or inclined plane H1. This roller normally bears against the spindle I owing to the action of a spring J surrounding a rod K iixed to the bent end E1 of the bar E and extending with slight friction through a hole E2 provided in a lug A2 at the front part of the guide-support A.

The tension of the spring J is regulated' by a small compressing nut L to which an arm M is fixed to prevent its rotation. The arm M bears against the guide A. The forward or rearward movement of this nut L is produced by turning the rod K, which is threaded on part of its length at L1. At its opposite end the said rod is provided with a notch K1, which, when the rod is moved towards the left, engages the hole E2 formed in the lug A1 of the guide-support A and thus retains the roller Gr at a distance from the spindle to allow, for example, of mending a broken thread.

For removing the cops when finished, it is suicient to lower the slide D in the ordinary manner. The bent, left-hand parts E1 of the bars E of all the elements are then acted on by a series of inclined planes N xed to a table O, and the rollers are simultaneously removed from the respective cop-spindles.

The end-position of the bar E is limited by a small nut P, screwed upon and serving also as means for securing in place the end of a bent wire Q which is carried by the bar E and forms at the same time a ring for guiding the thread coming from the bobbins.

The several movements of the yarn guide are produced by means of the mechanism shown in Figs. 4, 5 and 6. In Fig. 4, 1 is a driving pulley fixed to a shaft 2, to which is also fixed a cone pulley 3. The latter is geared by a belt 2O to a cone pulley 4 loose on a shaft 5. A spur wheel 6 is fixed to the pulley 4 and meshes with a spur wheel fixed to a counter shaft which is connected by a train of gear S, 9, 10 to the shaft 5. To thc shaft 5 is fixed a worm 11, which engages worm wheels 12 and 13 fixed to vertical shafts 14 and 15 respectively. To the shaft 14 is fixed a cam 16 (Figs. 4 and 5), rotation off which imparts reciprocating movement to the slide D carrying the bar O. This movement is transmitted to the slide D by means of a chain 21 attached to a lever 22 which is fulcrumed at 23 and carries a roller 24 resting on the cam 16. The said chain is also attached to a drum 25, and

. 36 xed to a shaft 37. The drum 25 to which the chain 21 is attached is also xed to the shaft 37, so that the rotation imparted to the latter by the worin gears causes the chain to be slowly wound on the drum. The pull thus exerted on the chain gradually moves the levers 2S and rollers 26 and 27 into the positions indicated by dotted lines in Fig. 5, and by this means the shaft 29 is slowly rotated to lift the slide D. During this lifting movement the rotating cam 16 alternately lifts the lever 22 and allows it to descend to normal position by gravity. The lifting of the lever 22 and the consequent yielding of the chain enable the weight of the slide D and parts xed thereto to rock the shaft 29 through a certain angle; the lowering of the lever 22, and Ythe draf exerted thereby on the chain, cause the sha 29 to rock through an angle in the opposite direction. This rocking movement is additional to the slow rotation imparted by the drum 25, so that the slide D receives reciprocatory motion simultaneously with its upward feed motion. The shaft 15 rotated by the worm wheel 13 has a crank arm 17, the pin 18 of which engages A,a slotted arm fixed to a slidable ban The latter has projections engaging the belt 20 on the cone pulleys 3 and 4, so that during the longitudinal displacement of the bar 19 by the crank arin 17 the belt is shifted on the said pulleys. By this means the speed of the shaft 5 and worm gears is gradually altered forthe purpose of imparting the desired conical shape to the cops.

When the machine is started the rollers G bear against the spindles I, which, owing to their continuous rotation, rotate the said rollers. As has been statedthe latter have a reciprocating movement of suitable amplitude combined with a slow upward displacement. Since, however, the grooves I-I encircling the rollers are inclined with regard to the axes of the latter, it follows that the threads passing through the said grooves receive ,a third movement of rapid reciprocation, the amplitude of which is equal to the distance between the highest and lowest points of the inclined grooves in the rollers. This third movement is of considerable importance, since it imparts a close crossing of special pattern which assists in preventing the disintegration of the cop. Moreover, the fact that the roller G to secure by Letters Patent of the United l States is 1.
