Serial No. 635,261.

atedfrom a single driving-means and traverse-mechanism, As shownniore particu larly in Fig. 3, v the winding-mechanism comprises a drive-shaft 3 journaled in bearings 4 in the frame or casing 5 and carrying. a helical gear 6 which meshes with a similar gear on the winding-shaft or spindle 10.

The winding-spindle 1O isjournaled in bearings 9in the casing 5 and the gear 7 is free to turn thereon, being adapted for rotative connection therewith by means of a suitable clutch-device 11. The clutch 11 is not herein shown in detail as it may be of any suitable construction as usually employed in machines of thepresentetype,

Suffice it to state that the clutch-member 12 is keyed to the spindle 10 and normally'held inengagement with the gear 7 by means of a coiled spring 14: hearing against a collar 15. y A tapered flange 16 on the clutch member 12 is adapted to be engagedlby a shoe 17 on a suitable lever 18, see F ig. 1, whereby the clutch may be released; either automatically or manually, to disconnect the winding-spindle 10 from the drive in the'usual manner as well known to those versed in theart'. I

The winding-spindle 10 projects outwardly beyond the end of one of its bearings 9 and carries a chuck 19 for holding-a core or spool 20 on which the wire w or other conductor is wound to produce a coil of any desired form and dimension.

Arranged in opposite, parallel relation with the winding-spindle lO is a traversetraverseme'chanismto be reciprocated therefrom to operate the traverse-guide 25.

The guide consists of an ar1n'26 having a hub 27 secured'to the traverse-rod 22 by any suitable means such as the binding-v screw 28; At the outer end of the arm 26 is a grooved guidewheel 3O around which the w re to leads to the winding-mandrel or spool 20 in the manner as shown in Flg. 4:.

It will be understood that the traverse-rod 22 may extend through a series of the frames or casings 5,to carry the guides for. a plurality of wlndlng'units; and likewise,

' the main drive-shaft 3 may be extendedv for driving cone'otion with all of the-windingspindles of the several head's; As before indicated, the. traverse-mechanism for the single or plural winding-heads constitutes a separate unit which is combined with the mechanism for driving the machine and contained in a casing or box 31 shown in Figs. 1 and 2. As here illustrated a power-shaft 32 is journaled in bearings in the casing 31 and projects therefrom at one end to adapt it to be coupled to the drive-shaft 3 for the winding units. Any suitable coupling-means such as that shown at 29 may be employed for rotatively connecting the shafts 32 and 3, or if preferred, a single continuous shaft without couplings may be used. At its opposite end the shaft carries a bcltpulley 34 or any suitable means for connecting it with a motor or other source of power. l'fidway between the bearings 3333, the shaft 32 carries a screw or worm 35, preferably formed integral therewith, and adapted to mesh with a worm-gear 36. The ear 36 is journaled on the reduced end of a vertical stud-shaft 37 held fixedly in a bearing 38 formed as a part of the casing 31.

A heart-shaped cam ll) is mounted to turn on the upper reduced end of the studshaft 37 and is secured rotatively with the gear 06 by means of a screw ll which binds it against the face of the gear. The cam 10 is adapted to reciprocate a slide 45 which carries opposite rollers 4:6 arranged to travel on the peripheral surface of the cam.

As shown in Figs. 1 and 2, the slide 45 may consist of a relatively flat rectangular plate resting on top of the cam l and slidable in a guideway 47 formed as a part of a circular disk or turntable 48. The disk 48 is seated in a circular, flanged recess l9 formed in a horizontal web or partition 50 extending across the casing 31 and supported from its sides. The guideway 1 7 for the slide" may be constructed as a slot or trackway extending diametrically of the disk 18 and provided with opposite, parallel bearing surfaces l i between which the slide is received. The disk 4.3 is adapted for rotative movement in its recess 49 in the web 50 and may be secured in position by any suitable means whereby to maintain the guideway H in its adjusted relation as shown in Fig. 1. As here illustrated, the disk or turntable ts is held in its recess and clamped fixedly in position by means of suitable bolts 51 screwed down into the web 50 with their heads binding against washers 52 overlapping the edge of the disk.

The traverse-rod 22, previously referred to, extends across the top of the turn-table l8 with its axis intersecting the axis of the worm-gear 36, being slidably mounted in bearings projecting inwardly from the sides of the casing 31. On the traverserod 22 is a crosshead 55 having a hub 56 secured to the rod by a set-screw 57 or any other suitable means. The crosshead 55 overlies the slide 45 and is provided with a slot or groove 58 on its under side adapted to be engaged by a roller 60 journaled on a stud 61 projecting upwardly from the slide. The slot 58 extends at right-angles to the axis of the traverse-rod 22 and it is therefore obvious that as the slide 4:5 is reciprocated in its guideway 47 under the turning action of the cam l0 the roller 60 will play back and forth in the slot to impart a reciprocating motion to the crosshead The method of operation of the complete machine is asfollows:

When power is applied to the pulley 34 on the shaft 32 the latter drives the connected shaft for one or more winding units, and rotation is transmitted therefrom to each winding-spindle through the gears 6 and 7 and clutch 11. spool carried by the chuck 19 on the spindle 10 will thus be rotated to wind on the wire or other strand w as the latter leads through the groove in the guide wheel which directs it to the coil as i shown in Figs. 3 and 4.

Referring now to Figs. 1 and 2 the power-shaft 32 also drives the gear 36 from the worm to rotate the heart-cam with a relatively slow motion. The cam 40 is thus caused to reciprocate the slide through the engagement of the cam with the rollers 46 the extent of this movement of the slide in its guideway being constant as defined by the eccentricity of the cam with respect to the axis of the gear 36 with which it revolves. As before explained the slide 45 is connected by its roller to reciprocate the crosshead 55 and the ex tent'of throw of the crosshead is regulated ments and such adjustment is accomplished as follows: Before starting the winding the clamp-bolts 51 for the turntable 48 are loosened so that the latter may be adjusted rotatively about the axis of the cam 40. The turntable may be adjusted while the machine is being turned over by hand, or running under power, and the guideway or track 47 may be inclined at varying angles to give an accurate and 'minute degree of adjustment in regulating the throw of the guide 25 within the prescribed limits. It will be obvious that if the guideway 47 is set in parallel relation with the The core or transverse-rod 22, or in other words, in line with the path of movement of the cross-- the guideway 47 at an angle to the path of movement of the crosshead 55 the operative effect of the reciprocating motion of the slide is altered to shorten the stroke of the crosshead. and that of the guide 25 reciprocatedv therefrom. That is to say, as the guideway 47 is inclined away from the axis of the rod 22 the extent of reciprocation of said rod will be gradually shortened until, when the guideway has been turned through an arc of-ninety'degrees, the movement of the slide 45 will be at right-angles to the rod 22 and hence the roller will slide back and forth in the groove 58 of the crosshead 55 without imparting any motion to the traverse-rod.

It will thus be seen that the traverse or stroke of the guide 25 may be adjusted from a maximum equal to the full stroke of the slide 45 down to a minimum of zero and with the utmost degree of exactness between these points. The traverse of the guide may therefore be regulated in accordance with the requirements of all sizes of coils required up to the maximum capacity of the machine with a minute degree of adjustmentheretofore unobtainable in machines of the present type.

It is also to be noted that my improved device makes for greater facility and convenience in the adjustment of the traverse besides providing for such adjustment without stopping the machine. That is to say, if the stroke of the traverse-guide requires further adjustment after the machine is started, such adjustment may be made without stopping the winding.

It is further called to attention that in the present improved device the adjustment of the traverse is made without change or replacement of any of the elements of the mechanism so that the machine need not be taken apart or disassembled. Moreover, the improved device is extremely simple in con struction, positive in action and proof algainst derangement or getting out of or c er.
