This invention relates to winding machines and particularly to a machine for winding or spooling wire and other attenuated materials.

One obj ect of the invention is to provide a winding machine wherein the spool or other receiver on which the material is wound is rotated from a drum or drive-roll whereby the rate of draft on the strand material remains constant from start to finish of the winding.

Another object of the invention is to provide a .winding machine having means for.

, or other receiver on which the material is wound through the intermediary of gearing adapted to be altered in ratio to provide for the proper disposition of the turns of the winding in accordance with the thickness or diameter of the material being wound.

Another object of the invention is to provide a winding machine of simple cnstruction, capable of operation at high speeds-to effect maximum production, with its mechanism proof against derangement or getting out of order and durable in use over long periods.-

Further objects of the improvement are set forth in the following specification which describes a preferred form of construction of the invention by way of example as illustrated by the accompanying drawings.

In the drawings: Fig. 1 is a front view of the improved winding machine showing its gear-casing in part section to illustrate thearran'gement of the gearing therein;

ing the gear-casing broken away and the winding-spindle bearing in section to illustrate the parts inclosed therein; and

Fig. 4 is a side view of the machine looking in the direction opposite to that of Fig. 2 and showing the gear-casing in section.

In the present embodiment of the invention the winding machine is shownas adapted for winding wire on spools, but it is to be understood that it may be employed for winding other kinds of material and different types of packages.

As shown in Figs. 1 and 2, the winding mechanism is mounted on a frame 2 comprising a base 3 adapted to be bolted to a table,- bench or other support and having upright side-members 4 which carry the bearings for the various shafts of the machine. The sidemembers 4 may be constructed in the form of posts or stanchions 5, 6 and 7 arranged in opposite relationatthe sides of the base and connected by web-like ribs 8. The forward stanchions 5 carry the traverse-mechanism, the rearward stanchions 7 serve as a' support for the frame in which the winding-spindle is j ournaled, and the central stanchions 6' are provided with bearings for the drive-shaft 10 which carries the friction drive-roll or drum 11. As shown more particularly in Figs. 1 and 3, the drive-shaft 10 is journaled in bearings 9 at the top of the posts 6 and extends beyond the side of the machine to adapt it to be connected to ,drive other units if desired. On its right-hand end, as Viewed in Fig. 1, is a suitable-belt-pulley 12 keyed rotatively therewith at 13 and secured inplace by a set-screw 14:. The hub of the pulley 12 abuts the'side of one of the bearings 9, and a collar 15 on the outside of the opposite bearingis secured to the shaft .10 by means-of a set-screw 16 to prevent longitudinal movement of the shaft.

The friction drive-roll or drum 11, shown in part sectional view in Fig. 3, is mounted on the shaft 10 midway between the bearings 9, being secured rotatively with the shaft by means of a key 18 and fastened in place by a set-screw 19 in its hub. Preferably, the roll 1 or drum 11 has a covering 20 of suitable resilient material such as leather or fiber on its periphery which is held in place by counterm 4 sunk screws 21. The drive-roll or drum 11 is driven directly from the pulley 12 which may be belted to a suitable source of power, for example, a line-shaft or an electric motor. The drive-roll or drum ll'is adapted to bear against the barrels of a spool S on which the winding is performed or to contact with any other suitable form of core or receiver to rotate the latter. As herein shown, the spool S is carried on a winding-spindle which is rotatably journaled in bearings on a swinging frame 26. As illustrated in Fig. 3, the frame 26 is provided with an enlarged hub 27, the ends of which are counter-bored to receive a pair of outer ball-races 28. A corresponding pair of inner ball-races 25) are held on the shank 30 of the winding-spindle 25 between a flange 31 at one end and a washer 32 at the other end. The

races

28 and 29 are of usual form adapted to receive balls 33 which revolve therebetween, thus providing an anti-friction bearing for the w ndingspindle.

The spool S is .received on the projecting portion of the spindle 25 and a hand-nut 35 is screwed onto the threaded end of the spindle to hold it in place. Preferably, the nut 35 has a tapered or frusto-conical portion 37 which cooperates with a similar tapered portion 38 on the flange 31 to enter the ends of the bore of the spool S to center it on the spindle and secure it rotatively therewith.

The frame 26 carrying the winding-spindle 25 is rockably supported on a cross-shaft 40 which is journaled in suitable bearings at the top of the posts 7 at the rear of the frame 2. As shown more particularly in Fig. 3, the frame 26 is provided at its rearward end with a forked portion or yoke 22 having hubs 23.

pivoted on the shaft 40. Referring to Fig. 2, the frame 26 is of elbow-shape in side elevation, being provided with a rearwardly extending arm or lever 24 shaped at its end to form a handle by means of which the frame may be rocked upwardly to remove the spool from contact with the driving-drum 10 when it is desired to arrest the winding operation.

' A detent-lever or latch 42 pivoted at 43 to the side of the frame 2 rests across the side of the yoke 22 of the frame 26 and is provided with a step or shoulder 44 adapted to drop into engagement with the edge of. the yoke when the frame 26 is raised into the posltion illustrated in Fig. 4. The lever 42 thus acts to sustain the frame 26 in raised position with the spool removed from contact with the driving-drum 11, the manual release of the lever permitting the frame to be lowered to replace the spool'against t e drum.

Referring again to Fig. 3, one hub 23of the frame 26 is held against the side of the bearing on the post 7 by means of a collar 45, and a second collar 46 abuts the side of the oppositehub 23 of the frame. and 46 are secured'fast to the shaft 40 by The collars means of set-screws 48 and thus serve'to prevent movement of the frame longitudinally of the shaft.

It has been stated that the winding-spindle 25 serves as the driving means for the traversing-mechanism of the machine and for this purpose it is caused to drive the rearward shaft 40 through a train of gearing carried on the side of the frame 26. The outer end of the shank 30 of the winding-spindle 25 is reduced in diameter to receive a spur-p111- ion'50 secured in place against the washer 32 which abuts the side of the outer ball-race 29 by means of a nut 5.2. The nut -52 is screwed onto the reduced threaded end of the shank 30 against a washer 53 and the pinion is keyed to the shank at 54. The pinion 50 meshes with a gear 55 which is carried on a stud 56 projecting through a hub 57 on the frame 26. The gear 55 is formed integral with 01' carries fast on its side a gear 60, the two gears being keyed to the stud 56 at 61 and secured in place by a nut 62 abutting a washer 63, it being understood that the stud 56 is arranged to rotate in its bearing in the hub 57 The gear meshes with a gear 65 which, in the present form of construction, serves as a change gear adapted to be replaced by others of different size to vary the ratio of the gearing. The gear 65 is rotatively journaled on a stud 66 held fast in the end of the arm 67, see Fig. 4, which is attached to the side of the frame 26 by means of a bolt 68. The bolt 68 extends through a slot 69 in the arm 67, thus rendering the arm adjustable to adapt it to be set in different ositions in accordance with the diameter 0 the change gears carried by the stud 66. The gear 65 is rotatively connected with a gear 70 by means of a slotted collar 71 arranged between the hubs of the gears which have lugs 72 engaging the slots in the sides of the collar. The

gears

65 and 70 are held in place on the stud 66 by means of a nut 73 and washer 74 abutting the side of the gear 70.

The gear 70, which also constitutes a change gear to be displaced by others of differvent size, meshes with a driven gear 75 keyed to the end of the shaft 40' at 76 and secured in place by means of a nut 77 and washer 78. It will be observed that through the train of gearing above described the shaft 40 is driven from the winding-spindle 25 at a greatly reduced rate of speed v which may be varied by substituting other gears for the

ehangegears

65 and 70. The shaft 40 is connected by gears 85 and 90 to drive an inclined shaft 80 which extends forwardly to the front of the machine to adapt it to drive the traversing-mechanism to be later described. As shown most clearly in Figs. 2 and 4, the rearward end of the shaft 80 is journaled in a bearing 81 on the side of the post 7 while its forward end turns in a bearing 82 projecting upwardly from the base 3 v thereto at 86 and held in place by a nut 87.

way may I bars or rods 107 held in ears 108 at the top The skew-gear 90 meshes with the similar gear 85 keyed to the shaft 40 at 91.

The above described gearing is enclosed and protected by a casin 88 arched over the top of the frame 26 an secured thereto by screws 89 passing through suitable ears 92 on the side of the casing.

The forward end of the shaft 80 is provided with a worm 95, either secured fast thereon or formed integral therewith as il-' lustrated in the present drawings. As shown most clearly in Figs. 1, 2 and 4, the worm 95 meshes with a worm-wheel 96 which is keyed fast to a cam-shaft 97 journaled in bearings in the posts 5. The shaft 97 carries 'a cylindrical cam 100 having its periphery provided with-a helical groove 101 which acts in the usual manner to impart reciprocation to a traversing-guide for the wire or other material to be wound. Asshown in Fig. 1, the cam 100' is keyed to the shaft 97 at 102 and secured in place by a set-screw'103. The

hub of the worm-wheel 96 is arranged be tween the end of the cam 100 and the side of one of the bearings on the post 5, whereby it cooperates with a collar 104 abutting the side of the bearing on the opposite post 5, and secured to the shaft 97 by aset-screw 105, to hold the shaft from axial movement in its bearings.

'Thetraverse-guide for the wire or other material is reciprocated from the cam 100 and may be of any suitable construction. As herein shown it comp-rises a carriage 106 adapted to slide on a trackway extending between the two opposite posts 5. The trackconsist of two parallel horizontal of the posts 5 by meansof set-screws 109. The carriage 106 is formed with a rearward portion 110 bored to receive-the rod 107 and forked bearings 111 straddling the forward rod 107. Projecting froma lug 112- on the under-side of the carriage 106 isa pin or stud 113 carrying a bowl or roll 115 which engages the helical groove 101 in the cam 100. Rising from .one side of the carriage 106 is a post 116 provided with an inclined, interiorly-threaded hole for receiving a thumb-screw 117 which is formed with atapered point 118.

Driven through a hole in the post 116 apin or rod 120 having its opposite end held in a hole in an ear 119 at of the carriage 106; Mounted to slide on the pin 120 is a vertical arm121 provided with a hub 122 surrounding the pin. The arm 121 has a forwardly extending leg 123 which is forked at its end to adapt it to straddle the in Fig. 4, by

the opposite side ear 119. I The spring 126 tends. to hold the arm 121 pressed against theconically pointed end 118 of the thumb-screw 117, and by turning the screw the arm may be adjusted one way or the other to set the strand-guiding sheaves or wheels 125 in alinement with the end' flanges of the spool S after the latter has been placed on the spindle 25.

In use the complete machine is operated as follows: The spool S, which is usually provided with a relatively large barrel and narrow end-flanges or heads, is placed on the spindle 25 and the hand-nut 35 screwed up against its end to clamp 'it in position with the tapered projections 37 and 38 tightly engaging its bore. terial to be wound on the spool is drawn off from its source of supply, carried around the periphery of. the first guide-sheave 125,

thence down under the second sheave, whence it is led to the barrel of the spool S to which its end is fixedly attached. While the machine is being prepared for operation the frame 26 is held in raised position, as shown the engagement of the notched detent-lever 42 with the yoke 22 of the frame. It will be understood that the drive-shaft .10 carrying the pulley 12 is driven continuously from any suitable source of power. Therefore, to start the winding operation it is only necessary for the operator to release the lever 42 and lower the frame 26 by means of the handle 24 until the barrel of the spool comes into contact witli the periphery of the drum 11, as shown in Fig. 2 of the drawings. The drum 11 will then act to rotate the spool S through contact of its periphery with the it-drives the winding-spindle 25 carrying the pinion 50 fast on its end. The pinion 50 turns th-e gear 55, and through the latters connected gear 60 drives the coupled changeears 65-and-70. The gear 70 drives the gear to rotate the rearward shaft 40 and the skew-gear carried on the opposite end thereof is caused to drive the gear to rotate the inclined shaft 80. The worm on the inclined shaft 80 drives the worm-gear 96, which, in turn, drives the shaft 97 to rotate causes the roll to travel in its groove 101 whereby the traverse-guide carriage 106 The wire w or other ma Ill) the cam 100. The turning of the cam is caused to be reciprocated back and forth on its tracks 107. The reciprocation of the traverse-guide causes the strand 'w of wire or other material passing over the guide-wheels 125 to be traversed axially of the spool S whereby to deposit it in helical turns disposed in adjacent relation between the end flanges of the spool.

It has been explained that the arm 121 carrying the guide-wheels 125 may be adjusted laterally on the carriage 106, this ad justment being performed when the spool S is first placed on the Winding-spindle 25. The spools S may vary somewhat as regards the size of their bores, and due to this they may not always assume the same position longitudinally of the spindle when the hand-nut is tightened against their ends. Therefore, to insure that the traverse of the guide-wheels 125 may register with the space between the heads of the spool S the position of the arm 121 carrying the wheels is shifted one way or the other as required by simply turning the adjusting-screw 117.

As the machine winds the wire or other material onto the barrel of the spool S it will be deposited in overlying layers of closely spaced helical coils, and as the diameter of the wound mass increases it will cause the frame 26 to be swung upwardly to accommodate the growth in the winding. When the spool is filled the frame 26 is lifted by means of the handle 24 to remove the surface of the wound material from contact with the drive-roll 11 to arrest the winding operation.

As the frame 26 is rocked upwardly the detent shoulder 44 on the lever 42 will engage across the edge of the yoke 22, and thereupon the frame will be held in its elevated position until it is desired to start the winding of a new spool.

It'will be observed from the foregoing that the present invention provides a particularly simple and and efficient machine for Winding wire and other materials onto spools or for packaging the same in other forms.

It is to be particularly noted that the spool or other receiver for the material is driven from a constantly rotating drum through the contact of the winding with its periphery. It will therefore be understood that as the wound mass increases in diameter the speed. of rotation of the spool will decrease, but on the other hand the lineal speed of drafton the material will remain constant.

As the rotative speed of the spool is decreased it is necessary that the rate of movement of the traversing-means for the wire be correspondingly reduced and this is accomplished by reason of the fact that the traversing-mechanism or reciprocating-means for the traverse-guide is driven directly from the winding-spindle; Through this arrangement of the mechanism the rate of traverse of the guide is regulated to deposit the coils of winding in predetermined relation to lay the material on the spool in smooth, even layers with a uniform spacing of the turns or coils of winding therein. It will further be seen that the speed of traverse of the guide may be adjusted in ratio with the speed of rotationof the spool in accordance with the diameter or thickness of the wire or other material being wound. This adjustment is I readily accomplished by substituting gears of different diameter for the change gears and 70. In changing the gears 65 and it is only necessary to remove the nut. 7 from the end of the stud 66, and in substituting other gears therefor their hubs are connected by the collar 71 and the arm 67 is adjusted to position to' bring the gears into mesh by means of the bolt 68 extending through the slot 69 in the arm.

The present improved machine is especial ly simple in design and sturdy in construction to render it durable in use over long periods. It is particularly to be noted that the machine requires no clutches or other manually-operated drive-control and thus its operating parts are reduced to the minimum. The improved machine operates with greater efiiciency to produce spools, packages or coils of Wire and other materials at high speed to render it capable of maximum productivity.

While the present specification and drawings illustrate a preferred form of construction of the improved winding or spooling' machine, it is to be understood that Various modifications may be made in the design and arrangement of the parts without departing from the spirit or scope of the invention.
