Specification of Letters Patent.

Patented Mar. 29, 1910.

Application filed October 14-, 1909. Serial No. 522,627.

To all whom it may concern:

Be it known that 1, Burns S. MATTnsoN, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Movement- Adjusting Devices for Traverse- Motion Mechanism for lVinding-h Iachines, of which the following is a specification.

This invention relates to improvements in movement-adjusting devices for traversemotion mechanisms for spoolers, skeinwinders and kindred textile machines, and it consists in certain novel features of construction and arrangement, all as more fully hereinafter set forth and claimed.

In traversemotion mechanisms of the class referred to and as usually devised and constructed, any material adjustments or variations in the traverse movement can be effected only while the spooler or analogous machine equipped with such traverse-motion device is temporarily stopped and inoperative a comparatively long time.

In the usual traverse-motion devices the zero position or base line from which the traverse movements are computed or determined is measured. from the center or mid-length. of the spool, and since the bottom of all the spools (irrespective of their length) are in horizontal alinement when normally mounted on the spindles, it is obvious that the position of the said base line will be changed accordingly. In other words, the base line is variable.

There are other objections or disadvantages to such former devices, for example, any change or adjustment of the traverse mechanism involves the stopping of the machine, as just stated, thereby correspondingly reducing the work or output and cans ing the loss of the attendants services for the time hem and a skilled operator or mechanic is necessarily required whenever variations in the traverse-movements are to be made.

Among the objects sought to be attained by the present invention may be mentioned the following: To produce a simple and conparatively inexpensive movement-adjusting means fortraverse-motion devices capable of being easily, positively, quickly and accurarely adjusted at will by the attendant or operator in charge, and without stopping the machine. The improved device is constructed, arranged and adapted to be readily substituted in lieu of certain parts of traverse-motion mechanisms as usually employed in spoolers, &c. That is to say, the device is capable of being operatively connected with the usual mangle, driving mechanism, lifting-rods and dogs, the flexible connections, traverse-rad and thread or yarn-guldes.

In the accompanylng three sheets of drawings, illustrating a traverse-motion device embodying the improvement forming the subject of this application for patent, Figure 1 represents a front elevation of the device in partion section, (corresponding with line 1 l of Fig. 2) the parts being shown as positioned to effect the maximum vertical movement of the traverse-rail. Fig. 2 is a corre sponding transverse or plane sectional view, taken on line 2 2 of Fig. 1. Fig. 3 is a front view similar to Fig. l, but showing the parts positioned to correspond with the minimum vertical movement of the traverse-rail. The said two positions in connection with the segment-gear, &c., correspond with the zero or lowermost position of the traverse-rail. Fig. 4 is a back View, showing the working face of the front disk-gear or scroll-plate, detached. Fig. 5 is a front side elevation, in reduced scale, showing a portion of a spooler and the improved traverse-motion device connected or associated with the mangle, driving means, lifting-rods, &c. Figs. 6 and 7 represent transverse sectional views, in partial elevation and enlarged scale, showing respectively long and short spools and also showing the relation of the traverser d thereto, corresponding with the posi-- tions represented in Figs. 1 and 3. Fig. 8 represents an end view of one of the clamping collars. Fig. 9 shows an end view of one of the links of the short, flexible connection or chain adapted to engage the spiral grooves of the oppositely disposed scrollplates; and Fig. 10 is a corresponding top plan view of it.

It may be stated in advance that the present invention or adjusting means is adapted to be successfully employed in spooling and winding machines as usually constructed and arranged, since it is capable of being substituted in place of the corresponding adjusting mechanisms of such former traversemotion mechanisms as are actuated by a rotary-reciprocating member or mangle; in turn driven by a continuously revoluble pinion-carrying shaft. It may also be added that the device actuates and controls the lifting-rods, which carry the traverse-rail, through the medium of intermediate connections in a well-known way.

Fig. 5 shows a portion of a machine of the type referred to. In lieu of the usual traverse-motion mechanism, the drawing represents a traverse-motion device, A, embodying my invention or improvement, as being substituted therefor. In said figure are indicated some of the parts or elements as usually devisedand employed, viz. :the end frame 1?, horizontal tie member B, revolubly mounted wheels C carrying flexible connections C the mangle M secured to an end of the horizontal shaft on, a tiltingly mounted, continuously revoluble shaft 8, having a pinion 8 (shown dotted) for actuating the mangle, and a sprocket or analo gous wheel to secured to the front end of the shaft 8 adapted to be driven continuously in one direction by a traveling chain 20 from any suitable or convenient source of power. The traverse-rail T is supported and carried by vertically guided lifting-rods L, each having a dog, L adjustably secured to its lower end, to which is attached a connection, C all substantially as usual, and as indicated in Figs. 5, 6, and 7.

The improved traverse-motion device A is secured to a suitably supported short transverse shaft, 17.; motion being transmit ted to it by a small bevelgear, m fixed to the forward end of said mangle-shaft m, meshing into a toothed quadrant, n fastened to shaft 11. As thus arranged, the latter is adapted to be slowly actuated in a rotaryreciprocating manner, substantially as usual.

The improved traverse-motion device proper, A, embodies in its construction a pair of laterally separated, disk-like gears, 1 and 2, each having its inner face provided with a spirally formed continuous rib and groove, extending outward from the center portion; a main frame or casting member a disposed between and supporting the disks upon its hub; an interposed live fulcrum member, 6, capable of independent movement in a vertical plane and being in continuous engagement with the spiral grooves and frame and attached to said mounted connection C in turn attached to a dog, L of the lifting-rod L; manually controlled means arranged to cooperate with. said gears for changing the position of the fulcrum member, nearer to or farther from the gears center, so as to vary the traverse movement accordingly, and means for clamping the gears to the frame a after the adjustl ment has been effected, whereby all the parts of the device are adapted to rotate together bodily in a circular arc, as determined by the said usual mangle M, gear m and its companion member or quadrant, n". The said frame or casting a is provided with a pair of oppositely formed thin sides or wings, a integral with the center hub a and an outer extension, (f, the latter forming a bearing for a short, horizontal shaft (Z. A pinion-gear, g is secured to each end of the shaft, and being in continuous engage ment with the teeth of the corresponding disk-gear. The front end, al of shaft (Z is adapted to receive a crank, 7c, thereby providing m ans whereby the disk- gears 1 and 2 may be readily rotated simultaneously in either direction, as desired, and as clearly shown in Figs. 1 and The said hub part, a is bored to receive and is adjust-ably secured to the suitably mounted and supported, horizontal shaft 01., the latter being actuated in a rotary-reciprocating manner by the mangle M, &c., substantially as hereinbefore stated. Each outer face or edge, (4*, of the upper portion of said wings has the form of a true circular are described say from a center .2 and a radius 2 tangent to said wheel C. See Fig. 5. The lower por tion of the wings of the frame terminate outwardly in the short, transverse tie, a its inner surface, a being disposed with respect to said edges a and adapted to constitute a bearing for the said fulcrum member Z), soon to be described. Each of the said disk-gears, l and 2, has a plane face provided with a continuous rib and groove, y, arranged in the form of a spiral, the pitch or distance radially between the convolutions being preferably made uniform, substantially as shown in Fig. at, which represents the rear face of the front gear 1. The spiral rib and groove of the adjacent front face of the back or companion gear, 2, are arranged to register or coincide with those of gear 1. In other words, one gear has a left-hand and the other a right-hand spiral groove. It may be stated that for the sake of greater clearness in the drawings, the major portion of the spiral ribs and grooves are omitted from Figs. 1 and 8. Fig. 4, however, represents the front gear 1, in. which the spiral members are shown in full.

The movable fulcrum member 7) is or may be made of cast metal; it has a downward extending arm or shank, o, the same when in use being located between the wings a of the frame member, and terminates in the end part, 7F, adapted to bear against the said inner surface a. The upper portion of the member 7) is provided with a pair of oppositely disposed front lugs, 7f, in frictional contact with the respective curved edges (i The length of each of the surfaces a a, exceeds the vertical movement of the member Z), as in adjusting it from the position indicated in Fig. 3 (corresponding with the minimum traverse-movement) to that represented in Fig. 1 (corresponding with the maximum traverse-movement).

The fulcrum member has a curved rearward extension, 6 at its upper end, provided with oppositely disposed lateral lugs, 6 slidably fitted in the grooves g of the respective gears. Said portion 6 is provided on its underside with a transverse notch, 6 adapted to be coupled or attached to a ointed or bendable element engageable with and capable of automatically flexing to conform to said grooves y The member 6 has an ear, 6, to which is attached an end of the said usual connection, C the latter in this case normally bearing upon the said curved part, 6 and extending therefrom to and around the supporting wheel C. See also Fig. 5.

The bendable element above referred to as being attached to the fulcrum member Z) is represented in the drawings as consisting of a plurality of interchangeable, interlocking links, it, of peculiar construction, arranged to form a short chain. Each link, shown in detail in Figs. 9 and 10, comprises a substantially flat base part, 7L1, having a relatively short tooth, if, on its upper side at one end, and at the opposite end an overhanging bent extension, 7%, having a recess, 7L3, formed on its underside, adapted when in use to interlock with the tooth of the adjacent link. The length of the link is the same or slightly less than the transverse distance between the disks at the bottom of the spiral grooves, into which latter the ends are slidably fitted; the length of the tooth and also that of said part h is such that the chain is capable of being moved freely between the adjacent faces of the spiral ribs while adjustments are being made.

In order to readily position or adjust the parts of the device so as to vary the vertical movements of the traverse-rail as desired, or to correspond with the length of spools on which thread or yarn is to be wound, a flanged clamping-collar, c, is movably fitted on each end portion, a, of the hub of the frame member a. Each collar has a plurality of bosses, 0, having longitudinally extending holes, 0 registering with corresponding holes formed in the said hub, adapted to receive therethrough the long bolts 6. See Figs. 1, 2 and 8. ns thus arranged, the act of tightening the bolts causes the two disk-gears to be frictionally clamped between the faces of the respective collars and the adjacent faces of the center flanges of the wings a and also to the bendable member 2. And since the casting a itself is secured to the rock-shaft n by set-screws (Fig. 2), it is obvious that the device as a whole will then be capable of movement bodily as a unit by and in unison with the shaft. Upon loosening the bolts 0 and applying the crank to the shaft (Z the disks may be readily turned in either'direction to vary the position of the fulcrum I) up or down, as desired, which action at the same time cor respondingly moves the chain connection It in the spiral grooves g farther from or nearer to the center of the shaft 71. After the adjustment has been effected the bolts are retightened, the device then being in condition for normal operation again. The front gear 1 (Fig. 5) may have permanent arrows, designated S and L, for indicating the direction the disk-gears are to be turned in positioning the fulcrum Z) and chain h. S corresponds with the short and L with the long traversemove ment. bolts after adjustment is not strictly necessary but is done to prevent the disks from being accidentally turned axially a short distance, as might possibly happen, such movement obviously acting to correspondingly alter the fulcrums position and are travel.

In Figs. 6 and 7 are represented, respectively, long and short spools, S, S carried on revoluble spindles z mounted in suitable spindle-supports, It, secured in the spindle-rails R, substantially as usual. The vertical lifting-rods L (one only being shown) carrying the horizontal traverse-rail T, are represented as being in the lowermost position, or at the zero or base line 0, the latter being coincident with the lower end of the spools barrel. The line 3 indicates the thread as it would appear upon being delivered, say from supply-bobbins (not shown) below.

The shaft 8 rotates in one direction only; some of the other parts, including shafts m and n, are adapted to move in either direction, or in a rotary-reciprocating manner; while still other parts, as for example, the lifting-rods which carry the traverse-rail, have a reciprocating-rectilinear movement. Practically all the figures represent the quadrant-gear n as being in the elevated or upward position, as determined by the corresponding position of the mangle. Now, upon starting the machine, the action of the mangle will slowly rotate the shaft 'm, and gear m less than a complete revolution in the direction indicated, thereby causing the improved traverse-motion device A to swing bodily in the arrow direction or toward the right through a circular are having a length corresponding with the relative sizes of the pinion m and quadrant n Said movement at the same time also causes the connections C attached to said device and the dogs L to elevate the lifting-rods L and traverse-rail T (see arrows) from the normal lower or base position 0 to the upper end of the spools barrel. The degree or The said act of re-tightening the i extent of this advance vertical movement is limited or determined by the previously adjusted position of the fulcrum member Y) with relation to its points of contact with the surfaces a a of the main member a. then positioned substantially as represented in Fig. 1 the traversemovement corresponds with the length of the longer spool S, Fig. 6, while Fig. 3 shows the fulcrum etc. positioned to correspond with the shorter spool S Obviously, the improved adjusting device is adapted to be readily changed to effect other lengths of traverse-movements by simply varying the position of the member b and its attached connection it, as hereinbefore described. Upon the return or reverse movement of the mangle the device will be actuated in a direction contrary to that indicated by the arrows until the parts are again in the first or normal positions; the operations described being repeated in a uniformly intermittent manner. It may be added that the degree of arc-movement, forward and back, of the device A is practically invariable, since it derives its motions from the usual mangle mechanism.

The normal relation and position of the various parts of the traverse-motion device provided with my improved movement-adjusting means are substantially as represented in Fig. 5 of the drawings, wherein the center 2 of the radius 2 for describing the are-shaped portion of the said edges a is located tangentially of the guide-wheel C, the arrangement being such that the fulcrum member, I), attached to the usual flexible connection C and passing over said Wheel to the lifting-rods L, is capable of movement outwardly from the lowermost position (represented in Fig. 3 and corresponding, say with the shorter traverse travel of the rail T) to the opposite eX treme position, shown in Fig. 1, without imparting movement to the said traverserail from its bottom or zero position 0, indicated in Figs. 6 and 7. And since the outer periphery of the chain ft or bendable element attached to the member Z) presents a substantially true curved surface on which the connection C is supported the latter will at all times lie tangentially of the wheel and said peripheral surface during the angular movements, forward and back, imparted to the device by the mangle; the length of the resulting traverse-movements, up and down, of the rail T being true and uniform and corresponding with the adjusted posi tion of the fulcrum member with respect to the said edges of the frame a.

I prefer to arrange the quadrantgear n so that it will be in the normally elevated position, substantially as represented in the drawings, when the mangle is on the dead center, so that the immediately following rotary movement of the mangle will, through the intervening mechanism, cause the device A to rotate as a unit in the arrow-direction, thereby, through the medium of the connection C etc., moving the traverse-rail T upward from the base line to the previously determined strokelimit, at which instant the mangle again passes its dead center, and is then rotated contrary to its former direction, thereby correspondingly reversing the devices movements and returning the rail downward to its base line 0 again; thus co1n pleting a double-reciprocation of the rail, the result being to lay two courses of the yarn uniformly throughout the length of the barrel of the revolving spools.

My improved variable adjusting means for traverse-motion devices for windingmachines is well adapted to be advantageously substituted in lieu of those employed in traverse mechanisms as usually constructed, and in which the winding-machine is provided or equipped with a traverse-rail, lifting-rods, and connections disposed with relation to the traverse-rail and traversemotion device, and means for actuating the latter in a rotary reciprocatory manner. Or, in other words, in a winding-machine equipped as just stated my improved adjusting or movement-changing device is constructed and adapted so as to be readily substituted bodily for the old travel-changing device and also arranged to be driven in a rotary-reeiprocating manner by the old actuating means, and being further adapted to be connected in the usual way to the said lifting-rods so as to actuate the traverse rails.
