Claims. (Cl. 242--39) This invention relates to a windin machine and has for one ofits objects the winding of two or more wire strands in parallel relation upon a take-up package that thereafter these strands may be helically laid together to form a cable.

Another object of the invention is to provide automatic means for stopping'the machine and preventing overrunning of the wire strands on the supply packages.

Another object of the invention is to provide a simple and yet efficient brake applying action to the supply packages.

With these and other objects in view, the inventlon' consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings:

These mandrels may be clamped to the horizontal bars ii at any convenient position therealong by the clamps l3 and tion ofthe upper part of the mechanism shown Fig. 3 is a top plan view of the forward portion of the control lever;

Fig. 4 is a top plan view of the clutch mech anism through which drive is transmitted to the take-up package;

Fi 5 is a front elevation of one unit of the machine showing the structure shown in Fig. 1;

Fig. 6 is a fragmental detail of certain moving parts of the supply package stopping mechanism.

The winder which is the subject of this invention consists of a frame of extended length with a driven shaft extending the length of the frame. Take-up packages are located at spaced intervals along the frame and each is clutched'to the drive Each of these take-up packages is fed from several supply packages locatedbelow and in front of the machine and mechanism is provided to stop overrunning of the supply packages upon the stopping of the drive of the take-up package. This assembly eonstltutes a unit complete within itself and a mulsupports extending therefrom. Each provides for the mounting of a package designated generally it on the mandrel by means of a clamping plate I5 and winged nut US which engages the central rotatable shaft I]. The mandrel freely rotates about the support upon bearings 98 and I9 provided therefor. A strand ofwire 20 is wound between the heads 2| of the package and is led upwardly as at 22 from one package and upwardly as at 23 from a second package vertically above the first package. A guide may serve to keep the wire strand 22 clear of the package above it but as the surface is traveling at the same speed this is usually unnecessary. These wir'e strands 22 and 23 (or more if used) are fed upwardly by the feed rolls 25, 25 mounted in bearings along the frame which serve to meter the supply so that the same length of wirein each of the parallel strands is provided. The strand then enters into the groove of the traverse roll 26 which is mountmachine. In the present instance as there are package from shaft ss throughgears 90, 9|, 9:,

9 3 and 84 on the shaft 25'. This train of gears tiplicity of these are located along the frame to be 'drlvenfrom 'the common drive shaft when clutched thereto.

This invention relates more particularly to a mechanism for bringing an individual take-up package to rest upon that package having become winding is brought to rest I cause the supply'packtwo packages provided so there will be at least two slots in this separator. If three parallel strands from three packages M were being assembled three slots would be used. The strands lead through these slots, and are maintained in.

parallel relation-to the delivery or take up packa e designated generally 3!. The feed rolls 25, 25' are driven from the drive for the take up may be positioned-at one end of the machine and are indicated in dot-and-dash lines in Fig. 1. The. feed rolls have a surface speed a little less than the surface speed of the take up roll. The traverse bar "may be common to all of the takeup packages along the frame and is slowly reciprocated back andforth lengthwise of the bar 28- to lay the wire in parallel relation upon the package 81-. This traverse mechanism is not shown as it plays no part in the inventive concept oi this application.

The take-up package 3| is mounted upon an arbor 32 which may drop into suitable bearings at either end and from which the package 3| may be conveniently removed. This arbor 32 is driven by means of a gear 33 secured thereto which meshes with a gear 34 which is slidably related to the main drive shaft 35 of the machine (see Fig. 4). The gear 34 has a conical recess 35 which frictionally engages the tapered driving member 31 held upon the shaft 35 by a set screw 3 8. When this gear 34 is moved to the right as shownin Fig. 4 clutching engagement exists between the tapered surfaces so as to cause the shaft 35 to drive the gear 34. The clutch gear 34 has a tubular extension 39 which is bushed as at 40 to slide along the shaft 35. A spring 4| abuts the shoulder 42 of this bushing and tubular extension 39 and is compressed between this abutment and the ball bearing member 43, one part of which rotates with the spring and gear while the other part is held to the shaft 35 by a collar 44 and set screw 45. This spring applies sufficient pressure to move the clutch parts into engagement. A housing 46 extends over this ball bearing and spring, which housing turns with the shaft and part of the ball hearing which rotates with the shaft.

The clutch gear 34 is withdrawn by a yoke 41 (see Figs. 1, 2 and 4) have bifurcated arms 48 which engage the flange 49 of the tubular part 33. The bifurcated ends may have roller bearings as illustrated. This bifurcation 4'! is at the end of an arm 50 which is secured to the shaft to rock in response to rotation of this shaft (see also Fig. 2). This yoke 41 is held to the shaft by set screw 52.

locationsuch that when the lever is in its uppermost position, such as when pressed by the spring 13, the operating rod 55 will engage this latch At the opposite end.of this shaft 5| an arm 53 extends which is bifurcated as at 54 to extend along either side of the operating rod 55.

This operating rod 55 is slidably mounted in a bracket 56 at its upper end and in a bracket 51 which drops down from a part of the framework of the machine. This rod 55 is urged upwardly by means of a spring 58 which abuts the lower bracket 51 and engages an adjustable collar 5-9 which is held to the rod 55 by means of a set screw 60. This spring is under such compression as to urgethe rod '55 upwardly at all times. The collar 59 also engages the bifurcated arm 54 so as to operate this arm when the rod moves upwardly. Spring 58 is of sufficient power to overcome the clutch spring 4| so as to disengage the clutch against the action of the spring justed position by a pin 65' (see Fig. 3) which extends through a slot 55 in the main portion of the lever and is held in adjusted position by the wing nut 51 which has threaded engagement with the pin 65' and draws the head "thereof snugly up against the arm 63 while the wing nut engages the main portion of the lever 5| so as to bind the portion 63 in adjusted position. A latch 10 tapered to a point II is secured to the lever 5| by means or the screw 12 and is in a and be prevented. from upward movement under influence of its spring 58.

As the package 3| is filled with wire the roller 55 is moved downwardly moving the lever 5| about its pivot 62 and moving the latch I0 gradually from a position over the rod 55. When the latch moves beyond a vertical position above the rod 55 the rod 55- will then be forced upwardly under influence of a spring 58 to rock the arms 53, 5|, 50, as a unit to withdraw the clutch and thus relieve the take-up package from further driving influence from the driveshaft machine. The rod 55 is reset by handle 24.

The supply package mandrels are both provided with bases 15 which are grooved as at 16 and I have extended a leather thong 11 about and in the grooves 15 of the lower package and crossed this thong as at 18 (see Fig. 5) so as to increase the engagement of the thong on portions of the groove 15 of the next upper package. Now this relationship may continue for other packages if desired after which-the thong has its ends 19 clamped as at by means of the bolt 8| which clamp is also fixed by means of set screw 82 (see Fig. 2) to the actuating rod 55. When the rod is' in its lowermost position the thongs "will be relaxed and will be loose about the grooves of the mandrel. However, when the actuating rod 55 moves to its upper positibn to release the clutch the thong will be drawn up tightly and will exert a suiilcient braking pressure upon the groove of the mandrel to stop these supply mandrels quickly and prevent any overrunning of the wire strands.
