12 Claims. (01. 242-25) My invention relates to a multiple strand spooling machine and is especially adapted to take-up and spool simultaneously the wires or strands as fast as they are delivered to it from a continuo annealing furnace.

Some of the objects of the machine are to spool the wires at a uniform linear speed regardless of the amount of wire onthe various spools; to properly and individually tension the wires in such a machine; to attain large spooling capacity in a compact machine with simplified spoolsupporting and driving means as well as simplified traverse operating means; and to provide readily effected, important adjustments of the traverse means for the proper laying on of the wires on the spools.

With these and othenobjects and advantages in view which will be evident to those skilled in the art from the following disclosure, the invention consists in the construction, combination and arrangement of parts hereinafter described and then sought to be defined in the appended claims, reference being had to the accompanying drawings forming a part hereof, and which show for the purpose of illustrative disclosure, but without limiting the invention to the details thereof, a preferred embodiment 'of the invention, it being expressly understood that various changes may be made in practice within the scope of the claims without 'digressing from the inventive idea.

Fig. 8 is a perspective view of one of the spool carriers detached.

The machine is driven'by an electric motor l0 f and speed-reducing chain and sprocket gearing ,Ila (Fig. 1) connects the motor with a large sprocket ,l;6-;on the horizontal transverse shaft it (compare Figs. 1, 2, 3 and 4) at the output end of the machine. This shaft turns in bearings 2. (Fig. 3) on the machine frame. 22 designates two pulleys secured one on each end of the shaft. The aforesaid sprocket wheel I6 is secured to'the ,rim of one of these pulleys (Fig. 3) so that the electric motor Ill drives both of said pulleys at speeds which are variable because the variable speed unit I which is of a well known adjustable ,cone disc type, as shown in Figs. 1 and 2, permits the imparting of variable speed to the shaft I8 through the said variable speed device and sprocket gearing Ila without requiring variation of the speed of the motor ll.

Two endless belts 24 extend lengthwise of the machine driven by the aforesaid pulleys 22, one by each pulley. These belts pass around idler pulleys 26 at the input end of the machine having individual bearings supported on the table of the machine and adjustable lengthwise thereof as by the screw means 28 to and from -,the beltdriving pulleys 22 to take up or adjust slack in the belts.-

The upper stretch of eachbelt runs above the table 30 of the machine and the lower stretch below the table, which latter is supported on, and in fact forms part of the frame of the machine. I

Under the upper stretch of each belt are rollers 32 (Fig. 1) freely turning on axles 33 supported on stationary brackets 34 supported on the table or machine frame. These rollers are idlers and support the upper stretch of the rimning belt. The spools about which it is the purpose of the machine to wind on the wires W are designated S and rest upon the upper stretch of the belts, some on one belt and some on the other. It will be understood that the spools S are not part of the machine, but=are insertable into individual carriers 36 forming part of the machine, so that the core or body portion of the spools rest on the given belt with the spool ends or'flanges straddling the width of the belt. Thus the traveling belts drive and rotate the spools resting thereon and wind the wires W thereabout. The linear speed of the wires is the same as the belt speed so that the winding-on tension of all the wires is substantially uniform regardless, of the fact that the rotary speed of the spools will be individually different depending on the extent to which they are empty or filled with wire. The individual spools when filled are removable without stopping the machine and replaceable by empty spools.

One of the spool carriers 36 is shown in Fig. 8 as a separate unit before it'has been assembled into the machine. Each carrier consists of a pair of parallel curved arms 36a rigidly joined by a support (as best shown in Fig. 6 as compared with Fig. 8) freely rotatable spindles or centers 38d and lie, the latter of which is resiliently endwiseoperable to enable the spool to be engaged with the centers tosupport it for free rotation thereon, and to be disengaged and removed therefrom at will. Each endwise movable spindle or center 36c has a cross piece or handle .38] through its outer end for operating it during the insertion and removal of a spool.

Figs. 1 and 1A show how the spools S alternate with the rollers 32, the former on top of and the latter below the upper stretch of the drive belts. The length and weight of the carriers 38 pivotally supported at 33 are such that the supported spools are maintained in frictional driven contact with the belt. Each carrier has a proppiece 3! pivotally depending from one of its arms. When the carrier is pivoted upwardly in order to lift its spool out of driven contact with the belt, this prop 38 pivots into a vertical position as shown at the right in Fig. l to. support the carrier out of operation, so that a filled spool can be removed and replaced by an empty spool, whereupon the prop 38 may be manually swung to one sideas shown at the left in Fig. 1, permitting lowering of the carrier and spool into belt-driven relation. A boss 36;; on an arm of each carrier acts as a stop limiting the aforesaid upward pivoting of the carrier substantially higher than its prop supported position by striking against the axle 33 of the overlying belt supporting rolier 32 as shown at the right in Fig. 1.

Over each spool S is a freely rotatable traversepulley 40 for guiding the wire in layers onto the spool. For this P p se the support on which each traverse pulley rotates is automatically reciprocated lengthwise relatively to the spool. The machine is built so that the supported spools S on the twobelts are in axially alined pairs across the machine so that the traverse pulley 40 for a spool on one side of the machine, may be and is mounted on the same traverse'rod 42 that supports the traverse pulley 43 for the alined spool on its opposite side of the machine, all as shown for instance in the end elevational view, Fig. 2, of the machine. There are as many traverse rods 42 as there are pairs of cross alined spools and these reciprocate endwise in stationary sleeves 44 supported on upright arms 41 piv-' oted at their lower ends to a relatively stationary part of the machine, as for example in the illustrated machine to the projecting inner ends (as shown in Fig. of the axles 33 on which the belt supporting rollers 32 rotate. Also see one of these arms 41 in Fig. 4. It will be seen from Figs.

2 and 5, that these stationary sleeves 44 and their supports 41 are located in the central longitudinal zone of the machine between and for the most part above the plane of the spooldriving belts and related parts.

Suitable means is provided, such as the screw means 48 for individually adjusting the angular position of each sleeve-support 41 about the alined axles 33 so as to raise or lower. each sleeve 44 for an adjustment purpose to be later explained. The wall of each' sleeve is formed with a longitudinal slot 45 wherein is slidably received a pin 46 projecting from the side of its traverse rod 42. This pin 46 is long enough to project between the tines of a fork "a on the upper end of an arm 50 which is fixed to a rocker shaft 52, Figs. 2 and 5. This rocker shaft 52 oscillates the forked arm 50 through an arc crosswise of the machine and it in turn, reciprocates endwise the related traverse rod 42 and the supported traverse pulleys 40 for delivering the wire in proper layers on the alined spools on thevtwo sides of the machine. The height of the pin 45 Fig. 5) in the fork determines the throw or extent of the aforesaid endwise reciprocation of the related traverse rod 42 and of the supported traverse pulleys 48 relatively to the length of the spools for properly laying the wire onto the spools; and

said aforesaid position of the pin in the fork and therefore throw, are regulatable by adjusting the previously referred to screw means 48, Fig. 4.

Another adjustment for the proper laying on of the wire is shown in Figs. 5 and 7 and consists of means for adjusting the position of the traverse pulleys 40 along the traverse rods." The illustrated means for this purpose consists of the following: each end of each traverserod 42 is axially bored out and screw-threaded. Its wall is formed with a slot 53; and it is surrounded by a screw-operated clamping band 54. Each traverse pulley 40 is bushed at 55 and rotates freely on a pin 56 .between a knob 51 secured to the pin and a shoulder formed by a larger diametered screw-threaded portion 58 of the pin which engages the screw-threaded socket'in the traverse rod. The foregoing is a convenient means for adjusting the position of the traverse pulleys lengthwise of this traverse rod. To do so, the clamps 54 are loosened, the knobs 51 are rotated to effect the proper adjustment, and this adjustment is then maintained by tightening the clamps to compress the slotted wall of the sockets against the threaded portions 58 of the pins. This operation can be-performed-without stopping the'machine.

It will be understood that the rocker shaft 52 extends substantially the full length of the ma.- chine as shown in Figs. 1 and 1A and that it supports and operates as many forked arms 50 as there are traverse rods 42 and pairs of alined spools 8. As a further adjustment, each forked arm is individually adjustable along the rocker shaft as well as angulariy about theaxis of said shaft. For this p se the lower end of each arm is formed with a half-concave part 59 to 1 which is pivoted at 80 a complementary half concave part 6 I, the two parts having their free ends joined by a screw bolt 62, so that the forked arms can be securely clamped in any adjusted position on the rocker shaft.

The means for rocking the rocker shaft to operate as described all of the traverse mechanisms simultaneously for guiding the wires onto all of the spools, is best shown in Figs. 2, 3 and 4, and is as follows: a crank arm 63 on the end of the rocker shaft supports a roller 64 which bears against the periphery of a heart-shaped cam 85. This cam is keyed to a short shaft 66 supported in suitable hearings in an oil containing casing 61 supported on the machine frame. A worm-wheel 68 fixed to the same short shaft is driven by a worm 69 keyed to the heretofore described belt drive-shaft l8, Fig. 3,. on which best shown in the end view (Fig. 2) fixed at one end to the rocker shaft and supporting a depending stack of weights II (compare m. 1) at its other end.

The foregoing completes the description of the machine except for the means for guiding the individual wires into the .end of the machine shown in Fig. 1A and for individually tensioning them on their way to the traverse pulleys and the spools. An upperframe work 12 is supported by suitable standards from the main machine frame well above the table at the input end (Fig. 1A) of the machine. Compare Fig. 2. This upper framework supports transversely extending horizontal rods or axles 18 on which freely turn numerous wire-guiding pulleys ll, one' for each wire coming into the machine. Ordinarily these wires will come direct from an annealing furnace not shown, and after passing .over the aforesaid guide pulleys will fan out and I! in each group at the corners of a square, the

wire being threaded zig-zag as shown in Fig. 1A about the pulleys and thence passing to one of the traverse pulleys l0 and the spool 8 upon which it is to be wound. The drag on the wire due to its zig-zag or circuitous path through the group of pulleys 15 serves to tension it. The more pulleys 15 in use and the more zig-zag or angular the path, the greater the tensioning. A

greater number of pulleys in each group than .sion that should be employed is determined by the diameter of the wireand its nature and temper.

Describing now the operation of the machine as a whole, the wires W are individually threaded over the pulleys 14 at the input end of the machine (Fig. 1A) and are then passed around the tensioning pulleys 15 shown in that figure and then over the traverse .pulleys 40, after which their free ends are attached to the spools S inserted between the spindles or centers of the carriers 36 with the body of the spools resting on the belts 24. The electric motor Ill, Fig. 1, being in operation, drives the belts 24 and thereby rotates the spools and winds the wires thereon. To throw any spool out ofoperation, it is only necessary to swing its carrier upwardly to the extent permitted by its stop 36g, whereupon its prop 38 automatically drops into place and supports the carrier with the spool out of contact with the belt. An empty spool can now be inserted, a wire connected to it and then lowered into rotary contact with the belt by swinging the prop 38 to one side out of its propping position.

The drive is such as heretofore explained that the linear spooling speed of all of the wires is uniform and substantially the same as the belt speed. This makes it possible to run the machine. continuously regardless of the amount of wire .on the spools and to change the spools as they individually become fully wound without interrupting the winding-on operation of the other spools.

The same pulley shaft'lt that drives the belts also drives the heart-shaped cam 85 which in turn operates the rocker shaft 52 that extends lengthwise of the machine between the two belts and reciprocates all of the forked arms 50 and all of the traverse rods l2 and the supported traverse pulleys II for the spools on both sides of the machine. This is a very efficient compact construction giving large spooling capacity, limited only by the length of the machine, which may be made longer or shorter depending on the capacity desired.

The adjustments heretofore described for the forked arms II on the rocker shaft, for the height of the pins it in the forks of said arms, and for the. positioning of the traverse pulleys 40 on the traverse rods, when once made, need not be changed except for a change in the diameter of the wires or some other essential change in the operating conditions.

The machine is especially suited as a take-up machine to spool the plurality of wires delivered from a continuous annealing furnace, or an enameling or tinning oven, or the like.
