MACHINE FOR OPERATING UPON WARP-THREADS.

Specification of Letters latent. I i Patented July 20, 1915.

Application filed June 25 1906. Serial No. 323,214.

Dorchester, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Machines for Operating upon Warp-Threads, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

Our-invention relates to machines for operating upon wrap threads, the same being herein embodied in a warp-uniting machine.

Our invention will be best understood by reference to the following description when taken in connection with the accompanying illustration of one specific embodiment thereof, while its scope will be more particularly pointed out in the appended claims. Inthe drawings,'Figure 1 is a front elevation, partially broken away, of a machine embodying one form of our invention; Fig. 2 is an end elevation of the same looking from the left in Fig. 1; Fig. 3 is a similar View looking from the right in Fig. 1; Fig. 4 is an end elevation on an enlarged scale, showing the upper portion of the warp compensating mechanism; Fig. 5 is an end elevation, partly in section, of the lower portion of said mechanism; Fig. (5 is a similar view showing the parts in a different relation; Fig. 7 is a plan View showing a portion of the two pairs of lease rods and the sleeves thereon; Fig. 8 is a sectional view of the lease'rods and their sleeves, showing the relation of the leased threads thereto, and F ig. 9 is a detail. Fig. 10 is a. detail showing locking means for the manual compensating device.

Referring to the drawings, we have there illustrated our invention by showing the same embodied in one specific form of machine which comprises a thread or warpuniting machine employing a thread-twisting mechanism for twistlng together the thread ends of the warp. v

The machine illustrated has supporting legs a, a, upon which are mounted the standards a, a. The two legs are joined by the two rods a", upon which is mounted for sliding movement the warp-unitingcarriage A. The standards are also joined by the two rods a over which the Warp threads are drawn when the warp is placed in tlpe, ma chine.

Each warp is mounted upon the machine for longitudinal adjustment relatively both to the uniting mechanism and the remaining warp by means of suitable warp holders or carriages, the same comprising in each case the end frame members I), united by the upper and lower rods 6', b and having at each end a pair of outwardly projecting hanger rods 6 supported in the frame upon roller supports 6, and also a similar pair of overhead hanger rods b", slidable in suitable 'recesses in the .standards a. This permits within certain limits a free adjustment of each warp support or carriage lengthwise the machine.

To the lower carriage rod Z1 upon each support is fastened a pair of inwardly projecting brackets b (Fig. 2) provided with clamping jaws b in which is fastened the clampbar which clamps the ends of the warp threads. riage is loosely secured a pair of upwardly extending arms or brackets 6 carrying clamping jaws Z) in which is secured the second clamping bar, the arms 6 being secured to fixed arms 6 of the carriage by tension springs b through which they are drawn against adjustable stop screws b. This permits the desired tension to be placed upon the threads of the warp.

Each warp before being placed in the machine is leased by the two sets of lease rods 0, c and (Z, d, to be more fully described, and, with its ends clamped in the end or lower clamping bar is led into the machine over the channel iron of the upper clamping bar andthe rod (6 and thence downward where the clamping bar is clamped in the lower clamping'jaws If. The lease rods are then placed in position in the end supports and the upper clamping bar inserted in its channel iron 6 to clamp the threads in position. Both warps when in positionhave the general relation shown by the dotted lines, (Figs. 2 and 3), where they are in a general parallel relation although the separate sets are individually spread and separated by the lease rods.

To the rod 1/ of each car-- Although any suitable movement may be given the related parts, in the illustrated machine, the warp supports, save for the compensating or adjusting feed to be described, are held stationary and the twisting mechanism is caused to advance endwise toby the cam A (see Fig. 1). The lead screw maybe turned by the hand crank e, for hand adjustment of the twisting carriage, but during operation of the machine it is driven from the main drive shaft 7' through change speed gearing supported upon the arm f swingingly mounted for adjustment about the drive shaft f at one end of the machine (Fig. 3). The drive shaft carries the driving pinion f meshing with the intermediate pinion f journaled on the swinging arm. The pinion 7" drives a similar pinion 7, the latter engaging with the larger gear f journaled in a bearing adjustably clamped in a slot in the swinging arm. The gear f turns the smaller pinion f, mounted co-axially therewith, the latter meshing with the gear 0 upon the end of the lead screw 6.

The drive shaft is driven through the pulley f at its opposite end from any suitable source of power. When it is desired to change the speed of rotation of the lead screw to alter the rate of advance of they twisting mechanism, the gears f and f upon the swinging arm may be replaced by other.

gears of a size suited to give the desired speed transmission, the arm 7" being adjustcloser thread spacing than the other and some compensation for this difference must be made to maintain the necessary measure of alinement between the uniting mechanism and the individual threads of each warp. While each set of warp threads may be adjusted relatively to the advance of the uniting mechanism, if desired, either automatically. or by hand, in the present machine we prefer to proportion the advance of the uniting mechanism with reference to vthe spacing or width of one warp,and herein the narrower one, and automatically but intermittently impart a slight movement to the remaining warp in a direction opposite to the advance of the uniting mechanism, thereby to Inaintainthe required alinement between the corresponding threads in the the corresponding pin is.

link 2' permits the proper swinging movetwo warps. The automatic compensating mechanism is, however, such that it'may be placed in operative relation to either warp support at will.

In addition to the automatic compensating mechanism, there is also provided means for manually adjusting either warp relatively to the other or to the uniting mechanism, such manual compensating means-being useful to correct localized irregularities in the spacing of the threads.

For the automatic compensating movement the lead screw shaft 6 is provided with the pointed cam 9 (Figs. 5 and 6). Disposed above the shaft 6 and transversely thereof is a slide it, having a handle 71/ and provided with a slot h", whereby the slide is permitted longitudinal movement upon the machine frame, being guided in such movement by the pin 71 projecting from the said frame. Pivoted to said slide are two links, a, 2', having their other ends connected to a cam member j through the instrumentality of slots 2" in said links engaging pins 7' upon said cam member which has two cam faces 7' and j. Upon the machine frame, beneath said cam member, are two pins Z, is. Said cam member is disposed above and in the same vertical plane as the pointed cam g. When the slide is in the intermediate position shown in Fig. (5, the cam member is moved thereby into the neutral or intermediate position there shown so that neither cam' face 7' or 3' can be acted upon by said cam g. When said slide occupies a position at one extreme of its movement, as in Fig. 5, the cam member will by the links 2', 2', be moved so that one cam face lies upon the corresponding pin in and the other cam face is brought into operative relation to the cam g. In the rotation of said cam g the point thereof engages the cam face j of the cam member and swings the latter in a vertical plane, the opposite end resting or pivoting upon The slot in the ment of said link, in accordance with the described lifting movement of that end of the cam member to which it is attached, the link attached to the other end of the cam member being substantially held from movement by a pin it upon the slide. moved to its limit in the opposite direction the position of the cam member and the links connecting the same will be reversed from the position shown in Fig. 5, so that the cam face j will be brought into operative relation with the cam g and the cam face 1' will rest upon its pin is. Near the opposite ends of said cam member are at- When said slide is corresponding ratchet Wheels Z Z and out of contact with the teeth thereof. Loosely connected with said studs are levers Z, Z*,

which are pivoted co-axially with the respeetive ratchet wheels and are adapted to 'be held in close frictional engagement with the faces thereof by the coil springs Z Z mounted upon the bolts Z"", Z. Upon the lower faces of said levers Z*, Z, near their pivotal points, are cars Z, Z, having set screws Z Z engaging the arms Z, Z, near prevented by the spring Z?) and thereby the pawl will advance its ratchet the proper distance. As the weight of the parts tends to keep the operative face of the cam member in engagement with the pointed cam 51, when the point of said cam shall have passed from engagement with the operative cam face, the

link Z Wlll be moved downward, thereby bringing the'lower edge of the arm Z in engagement with the set screw Z, and carrying with it the pawl. In the furtherdown- Ward movement of the link the arm Z will carry with it the lever1Z thus bringing-"said.

pawl into its normally inactive position.

Rotatably mounted in the upper portion of the standards a, (1', upon arms 8, s, is a rod 8'. That arm 8 mounted in the standard a to which the ratchets are adjacent, is eX- tended below its pivot, as shown in Fig. 4,

i and at its'lower end has mounted a sprocket -of either set of Warp threads with relation wheel 3 and a co-axial gear wheel a shown in dotted lines in said figure. Upon the rod 8, and in vertical alinement with the sprocket wheel 8 is a sprocket wheel a mounted for rotation, said sprocket wheels 8 and 8* being operatively connected bya sprocket chain 8 By manually shifting the rod .3 toward the front or rear of the machine the gear 8 may be brought into engagement with either gear-wheel s mounted co-axially with the respective ratchets Z Z to rotate therewith. The gear sprocket wheel a is under the manual control of the operative, being turned by rotation of rod 8', and when the gear 8 has been thrown into engagement with either gear 8" the corresponding ratchet may be given partial movement of rotation so that the position to the other may be altered by lengthwise movement of the holder or carriage whereon the sameis mounted. In other words, there is thus, provided manual compensating means that may be brought into operative warp holder or carriage, the warp holder or carriage which is thus under the control of said cam 9 depending upon the position of the slide 71..

The warp uniting carriage A, shown more clearly in Fig. 1, has standards m, m, rising from the base thereof. -Mounted in the upper end of said standard m is ashaft. mi

adapted to receive a movement of rotation by a pinion m and carrying at its opposite end a segmental plate m forming one element of the warp twisting member, said plate-being adapted inthe partial movement of rotation of the shaft m to be brought into engagement with the opposing plate m"- of the warp twisting member, said opposing plate being stationarily mounted upon an arm projecting from the warp carriage, as shown in Fig. 2. Said movable member m is provided with a thread cutting knife m shown in dotted lines in saidfigure. Thus the corresponding threads of the'two warps are twisted together, said threads being brought into close relation with each other and in a position to be twisted together by the helical hook it when the end threads of the two warps are in position to be engaged thereby. Said hook n is mounted upon one end of the shaft n which is adapted to be rotated by the bevel gear n upon the opposite end of the shaft, and driven by the bevel gear n, upon the shaft 11 mounted in suita bevel wheel a meshing with a similar wheel a upon the drive shaft f." Upon said shaft n is mounted a pinion 0 meshing with an intermediate pinion 0 through which I the desired movement of partial rotation is imparted to the pinion. m .upon the shaft m The shaft mipasses through the upright m upon the traveling carriage.

Mounted in the standards a, a, ofjthe machine are the lease rodsc, c, and Z, d. For each warp there are provided two lease rods, disposed in substantially vertical alinement, each being semi-cylindrical in cross section. The threads of the warp are leased as shown in Fig. 8 about said rods which are mounted with their curved faces oppositely disposed so that alternate threads of each warp pass from the curvedface of one rod in a. diagonal direction to and about the curved iace of the. other rod, cro'ssing'the remaining threads of the warp which have members.

an essentially true vertical position, owing to their engagement with the flat faces of said rods. Mounted upon the lease rods are tubular sleeves r, 7*, having shoulders r, r, at their forward semi-tubular ends, the

its movement upon the projection 39*.

function of said shoulders being to maintain the body of the respective warp out of engagement with the helical hook it and out of engagement with the Warp twisting mech anism, permitting merely the end threads of the two warps to be at the proper time engaged by said hook'and said uniting mecl anism. Each sleeve, and yn'eferably at or near the forward end of its tubular portion, is pinned to a block W as shown in Fig. 7, said block being semi-circular in cross section and having its flat face engaging the fiat face-of the corresponding semi-cylindrical lease rod, whereby each sleeve and its lease rod move in unison when a. movement of partial rotation is imparted to'the sleeve.

Viewing Fig. 8, it will be seen that the shoulders 1*, r, of a pair of lease rods are oppositely disposed. A movement of semirotation imparted to the lease rods 0, c, and d, d, and the sleeves 1*, 1*, will carry the shoulders r 1* out of en 'a ement with the 7 7 to b end thread of the warp, such as the thread r in Fig. 8, and will permit said thread (it being properly tensioned for that purpose) to snap or move into operative engagement with the helical hook and the warp twisting Such semi-rotation of the lease rods 0, c, and the sleeves r, T, will more the shoulders r, r, into engagement with what is now the end thread ofthe arp, being the thread r shown in Fig. 8, so as to niaintain the body of the warp in the position shown in Fig. 1. The lease rods 0, c, are so mounted in the standards a, as, that a movement of semi-rotation may be imparted to them by the described rotative movement of the sleeves r, 1", which are given a longitudinal movement thereon so as to maintain the body of the two warps well out of engagement with the hook it and the unitin members as shown in Fig. 1, but to permit the threads shown as deflected in said figure to be brought into closer relation with said parts at the proper time, so that the end thread of each warp may be engaged by the hook and the uniting members. This described action of the shoulders r, 1", upon the upright m. The blockv 20 is guided in The described movement of reciprocation of said sleevcsjis preferably so timed with regard to the movement of semi-rotation thereof, that when the end, threads of the two warps are permitted to snap past the shoulders thereon, the other threads of each warp stand in their normal vertical position. The

movement of said sleeves to the left, however, viewing Fig. 1, deflects or pushes the warps, r a portion thereof, as already stated entirely clear of the helical hook and the twisting member.

The lease rods 0, c, a), d, are given their described intermittent movement of, semirotation by reason ofpinions shown in dotted lines in Figs. 1 and 2, mounted upon the sleeves r, i, said pinions being driven in unison by a gear m, shown in dotted lines in Fig. 2. The pinion upon the sleeve for the lease rod (Z is intermittently moved by the star wheel m to wh ch movement is suitably imparted from the shaft 92..

It will be observed that the warp uniting machine is adapted to hold or sustain therein the full width of the two warps supported in series as described so that the warp uniting mechanism, the specific embodiment of which is a warp twisting mechanism, may act upon corresponding threads of successive pairs throughout the entire width of a cotton warp without any stoppa 'e or delay such as would be occasioned in a construe tion wherein. the machine could not accommodate-the full. width of the cotton warp but only sections thereof at a time, thus necessitating the application of successive sections of the warps to the machine before union of all the threads of the two warps is completed.

l ot only is the machine adapted for use without stopping or replenishing the same, to operate upon the full width of a cotton warp but it is also adapted for use upon any wide warp, whether of silk, cotton or any othermaterial. it is, of course, apparent that the machine is equally adapted for use upon narrow warps, such as, for instance,.

upon material to be used in narrow ware sill; looms. A peculiar advantage, however, of our mechanism is, as previouslystated, that it is equally adapted for operation without delay or stoppage upon an entire cotton warp, or other wide warp, as distinguished from what is known as a narrow ware warp.

In Fig. 1.0 is shown locking means to hold the gear a of the iinanual compensating means in engagement with the corresponding gear 8 of either warp holder or carriage, or in an intermediate position out of mesh with either of said gears. Upon the arm 8 is provided, in a hole therein, a pin w spring pressed by the spring 10 positioned between the end of the pin and the adjustin screw tions. The sockets, w, are so shallow that side pressure upon the manual operating of the two warps,

pa r.

means at either end of the loom client to release the locking means. Any other suitable locking means may be employed. w
