TRAVERSE MECHANISM FOR WINDING-MACHINES.

Application filed May 11, 1916. Serial No. earns.

To all whom it may concern:

Be it known that I, CLAEs RYDEN, a citizen of the United States, residing at Gran s ton, in the county of Providence, State of Rhode Island, have invented certain new and useful Improvements in Traverse Mechanisms for lVindin'g-Machines, of which the following is a specification.

My invention relates to winding machines and consists of an improved, adjustable traversemechanism therefor. The object of my improvement is to provide a traversemechanism capable of minutely accurate adjustment for diiferent lengths of traverse or throw of the winding-guide, and'particularly designed to insure a constant speed of movement of the guide throughout the full extent of its traverse to effect a precise and uniform disposition of the separate convolutions or turns of the winding laid in place by the guide. My improved device is intended for use particularly in machines employed for winding wire or other conducting-material in manufacturing coils for electrical purposes in which a regular and uniform relation of the windings is of utmost importance. l

The manner and means for carrying out my improvement are fully described in the following specification, illustrated by the accompanying drawings, in which like reference characters designate like parts. In the drawings Figure 1 is a front elevation of a winding.

Referring first to Fig. 1, the winding machine here illustrated is of a usual type comprising the main frame A in which is rotatably mounted the horizontal windingspindle or coil-mandrel B. Mounted on a secondary shaft 0 supported in bearings be- Specification of Letters Eatent.

low the spindle B, but not here shown in detail, are two traverse-cams C and C which may be driven through any suitable connections as usually arranged. trated the spindle B carries a pulley D at its rearward end connected by a belt (5 to a second pulley D which, in turn, is connected to the cam-shaft c by gearing E, E 111 the casing F. The cam C is secured fast on the shaft 0 to be driven directly thei'efrom; while the cam C is rotatable on the cam-shaft to adapt it to be turned independentlythereof. The cam C is driven at a relatively slower rate of speed than the cam 0, being geared to the spindle B through a worm-wheel G carried on its hub guides are employed to lay the coils of winding 1n place on the spindle or mandrel B. One guide traversed from the cam G acts to deposit the turns or convolutions of wire on the core or mandrel B ,while one or more other guides operated from the cam C deposit insulating-material, such as thread or yarn, between the layers of wire windings. This system of producing electrical coils is explained in United States Letters Patent No. 1,080,880, granted to Max I'IQlIH DGC. 9, 1913, in which the winding apparatus is also described and will not, therefore, be herein set forth. My present invention concerns more particularly the traverse-mechanism for the wire-guide and, as a matter of fact, is not closely related to the arrange- .ment of the guide for the insulating-aria ,particularly to coil-winding apparatus in which the prime essential is that the turns As here illusarm K. The sleeve is is free to turn on the lower rod 2', being pivotally mounted in a 1 cylindrical hearing it at the lower end of the arm K and also connected to a bifurcated arm K at the top of which is the wire-guide L. The guide L consists of a bifurcated member on which is journaled a grooved guide-wheel l, while an upwardly extending arm Z carries a rotatably-mounted, auxiliary guiding-wheel P. The wire 10 or other material to be wound on the spindle B leads down from its source of supply (generally arranged above the machine, but not here shown), passes under the grooved wheel Z and thence around the main guide-wheel Z to the coil \V. The guide-wheel Z is adapted to bear against the surface of the coil W throughout the winding and as the layers build up and increase in diameter the guide L moves away from the axis of the spindle B through the. swinging movement of the hinged arm K. The above described ar-- rangement of the traverse-guide L is com- ,mon to coil-winding machines of the type here'shown but is not essential to the present invention, as any other constructionv suitable for the purpose might be used in its stead.

Extending from the bracket H is an arm H which reaches around in front of the traverse-cam C and is formed with a hub it,

see Figs. 4 and 5. An arm or lever M is provided with an integral pin or stud m which is journaled in the hub h and serves as a pivot to adapt the lever M to rock about its axis. Fig. 2 illustrates the lever M in side View showing its lower portion as. of substantially U-shape with a vertical extension reaching up in the arm m. Depending from the U-shaped bend of the lever M is a bifurcated extension or arm m formed with a vertical slot m The upper arm m of the lever M is also provided with a vertical slot m extending substantially its full length, see Fig. 3. The lower arm m of the lever M is connected with the cam Cto impart an oscillatory inotion to the arm m,

or support'n The block a is fitted to a slot 72 inthe front of the arm H and secured thereto by a screw 72, reaching in from the rear. Driven through a hole 0 in the slide -O is a stud 0 on the inner end of which is pivotally mounted a block 0 held in place by upsetting the end of the stud 0 The stud 0 is formed with a flange'o abutting the front-face of the slide 0 and projecting through a horizontal slot a in the front of the track-N, 'see Fig. 2. Rotatablymounted on the forward end of the stud 0 is a roll 0 adapted .to engage a helical groove of in theperiphery of the cam C. The cam G acts through the roll 0 to reciprocate the slide 0 back and forth in its track or guideway LT and the block 0 on the inner end of the stud 0 engages the slot m in the lower end of the lever M to rock the latter on its pivot m. Through this means the cam-roll 0 is-caused to travel with a straight-line movement in a horizontal plane intersecting the axis of the cam C. In this manner the path of the cam-roll is maintained constant with respect to a fixed diametrical plane of the cam to prevent variations in the angular velocity of the traverse-lever M as more fully explained hereinafter.

At the outer end of the arm H is a vertical extension or upright H which, as shown in Figs. 1, 2 and 3, is formed as a part of the arm itself although it might be constructed as a separate piece andattached thereto inany suitable manner. The extension or upright H is formed with a relatively broad slot 7L extending the full length of its rear face, see Fig. 3, while a narrower slot [b4 is cut through its front portion. Adapted to slide up and down in the slot a on the back of the upright H is a block '29 carrying a horizontal .track or guideway P on its rearward side, see Figs. 2, 3 and 5. Referring particularly to Fig. 2, a stud p reaches through the slot h in the'front of the upright H and is screwed into the block ,2). Between the head of the stud p and the front of the upright H is a washer p which bears against a boss h to hold the block 29 in place in the slot it while allowing it to slide up and down on the upright. A bolt 29 also reaching through the slot 71, and screwed into the block p, isadapted to be set up against its washer p to bind the latter against the boss h and thereby clamp the block 3) in place in any position to which it is adjusted vertically on the upright H Referring now to Fig. 1, the adjustable guideway P on the block p is of cylindrical construction bored longitudinally at p to form a quill-like bearing extending horizontally across the front of the traverse-lever M. Referring to Figs. 2 and 3, thequill P is milled off or flattened along its rear side to adapt the lever to ride across its face 1? and to also provlde a slot 10 opening into nae-area the longitudinal bore 17 Adapted to slide in the bore 71 is a traverse-rod R which means of a stud 8 extending through a hole r in the block to allow the latter to rock slightly with respect to the rod.

The outer end of the traverse-rod R is joined to the guide-arm K by an adjustable coupling-device shown in detail in tl1e enlarged views, Figs. 6 and 7. Referring also to Fig. 1, a sleeve-like member T, fitted on" to the'rod R and secured thereto, is formed at its end with an enlarged head 25 provided with a notched quadrant t. A headed stud U formed with an enlarged body-portion u fitted to slide in a vertical slot 76 in the arm K has a smaller extension u, arranged eccentric to its main body, reaching through the member T. The stud U is held in place by a finger-nut u secured to its end by a pin a see Fig. 6, and carries a sheet-metal washer V abutting the front face of the member T. The washer V is fast with the nut u and is provided with" a spring detent-finger o bent into a point 1: at its end to adapt it to engage the notches t in the quadrant 25. By turning the finger-nut u the eccentric portion u of the stud U is displaced with respect to the main axis of V the stud to shift the arm K longitudinally of the rod R to vary the operative length of the latter. In this manner the traverse-guide L may be adjusted in relation to the trav- ,erse-arm M to regulate its position of traverse along the winding-spindle B. The engagement of the detent-finger 'v with the notches t of the quadrant t acts to restrain the stud U from unwarranted movement to maintaitn the parts intheir adjusted relation.

Referring now to Figs. 1, 2- and 3, a vertical rod X is rotatively mounted in'a hearing it at the end of the arm H and held in place byv a collar 00 at the upper end of the bearing and a finger-nut Y at its lower end. The. rod X is threaded throughout the greater portion of its length and extends through an internally-threaded bearing p on the slidable block 10. By turning the rod.

X the block 10 may be moved up and down on the upright H and through this means the quill or guideway P is adjusted with respect to the axis of the traverse-lever M to vary the operative length of the stroke of the lever in reciprocating the traverse-rod -R. Usually the upright H is marked with a series of graduations It providing a scale adapted to register with a pointer 10 on the washer P carried by the stud p. The scale it serves to indicate the length of stroke or traverse imparted to the guide L by the arm M acting through the traverse-rod R. The method of operation of the complete mechanism is as follows V In adjusting the machine for winding any prescribed length of coilthe bolt 79 on the block p is first released to allow the guideway P to slide on the upright H The fingernut Y at the bottom of the rod X is then turned to raise or lower the guideway P, as the case may be, to set the pointer p at any desired graduation on the scale it in accordance with the length of traverse re quired. P or instance, ifa coil two inches in length is desired, the pointer is set at :2 on the scale as shown in Pig. 1, while other fractional dimensions are provided for by the intermediate graduations on' the scale. After the track or guideway P has been set as above described .to give the required traverse, the lockingbolt p is set up against its washer p to bind the latter against the boss 55* on the arm H and thereby clamp the parts in their adjusted relation. Now, when the machine is started the cam G acts through the roll 0 engaging its groove 0 to recipro' cate the slide 0 in its guideway N. As the slide 0 moves back and forth the block 0 on the stud 0 rocks the lever M through its engagement with the slot m at its lower end, with the block 0 free to slide to a slight extent u and down in the slot.

As beiore explained, the slot m in the up per arm m of the lever M is engaged by the block S fastened to the connectingrod R. Henceas the arm m oscillates back and forth at the rear of the guideway P the traverse-rod R will be caused to reciprocate to transmit a corresponding motion to the vertical arm K connected to its outer end. The arm K slides with its sleeves 7c, is on the rods i, i andthe traverse-guide-arm K connected to the lower sleeve is reciprocated therewith to traverse the guide-wheels Z, Z longitudinally of the winding-spindle B.

The. wire to or other. material leading through the grooves in the guide-wheels Z, l" isthereby carried back and forth between the defined limits of the traverse of the guide and as the spindle 'B'rotates the turns of the winding are laid in close spirals which build up layer on layer to form the coil W. In the machine illustrated in the drawings provision is made for traversing .a second 3 relation to each other.

its oscillating-means is much simpler than the arrangement above described constituting the present improvement. Usually the.

connecting-rod for the yarn-guide is simply pivoted at its end to the rocker-arm oscillated from the cam C while being adjust able thereal'ong to regulate its extent of traverse. I With such a connection the guide will have a faster speed at the ends of its traverse than at the center, due to the arcuate path of movement of its point of connection on the traverse-arm, but as before stated the variation in the speed of the yarn-guide is not important.

As regards the wire-guide, however, it is essential that its speed of movement be absolutely constant and unvarying throughout the full extent of'its traverse, or otherwise the turns of coils of wire will be spaced farther apart at some points than at others. In winding electrical coils it is essential, to insure the maximum etliciency of the coil, that all the turns of the wire be laid in close juxtaposition and with a uniform spacing in My present improvement is designed to obtain this result with the use of an oscillating-lever for reciprocating the traverse-guide. By arranging the element 0 which rocks the lever M to travel in a straight line in the horizontal plane of the axis of the cam C, and by providing for guiding the point of connection of the guide with the lever M to also travel with astraight-line movement I accomplish this desired result. That is to say, the end of the traverse-rod R isconnected to the lever M and guided by the track P to be reciproeated with a right-line movement, instead of moving in an arcuate path.with respect to the axis of the lever. The block 0 also has its movement directed in a straight line instead of areuately with respect to the axis of oscillation of the arm M and therefore the move ment of these two elements is equalized to effect a constant speed of movement'as transmitted to the wire-guide L. In this way the speed of traverse of the guide is maintained constant from one end of its throw 'to the other and hence it will operate'to lay the coils of winding in place with a uniform spacing or relation.

In addition to the above feature my invention provides for a minutely accurate setting of the traverse-mechanism, similar to a vernier adjustment, 'for different lengths of justment of the connection between the outer end of the rod R 'and the arm K allows for setting the guide L laterally in relation to its traversing-means and longitudinally with respect to the winding-spindle, so that the traverse of the wire-guide may be regulated in respect to the traverse of the other guide for the yarn or insulation, whereby the two traverses will register properly required;
