In the embodiment of our inventionwhich we have herein disclosed, the threads of the two warps are held distended, parallelly arranged and opposite each other, and the uniting mechanism is caused to travel between them for the purpose of progressively actino thereon. It is of course, to be understood that the movement of the uniting mechanism and the ditierential movements of the warps, to be subsequently eX- plained, are required. to be relative only, and that the identity of the stationary element and the movable element is immaterial except as to simplicity of construction.

In the machine illustrated each series of warp threads is carried in a frame or carriage supported by the two hangers a, a (Fig. 1)'depending from the .rods a a, movable on the rollers a a and having thereby a limited movement for purposes of adjustment lengthwise the machine.

The rollers a a are journa-led in the branched frame members I) carried at the opposite extremities ofthe bed piece B of the machine, the latter being supported upon suitable standards B.

While certain features of the invention have application to machines adapted for purposes other than warp uniting the principal use of the illustrated embodiment of the invention is to oin the thread ends of an old warp which has been in the loom to those of anew warp. And while certain features of the invention may be usefully employed in joining the ends of either a leased or an unleasedwarp, the mechanism herein described is particularly adapted to meet the requirements in the case of commercial warps where crosswise or transverse sections of the warps, held between clamps or other holding devices in unleased relation and with the threads-substantially parallel but normally irregularly spaced, are required to be united.

Referring to the warp uniting machine herein illustrated, the two warp rolls one with the old warp as it has been withdrawn from the loom with its attached harness and reed through which the threads are drawn, and the other one with the new warp, are supported adjacent the machine on opposite sides thereof by means not shown, but which may consist of separate frames or attachments to the Warp frames of the machine. The two thread holding frames are substantially similar. In each case and on each side of the machine the entire series of threads passes from the warp beam or roll to the gripper bar a upward and toward the center of the machine, over suitable thread separating devices and downward and outward to a second gripper bar (not shown) carried in the clamp pieces a (Fig. 17). The upper gripper bar is adjustably mounted to hold the threads distended under suitable tension, and, when in position and thus held, the two crosswise warp sections are held stretched in a general parallel relation to each other and parallel to the line of movement of the thread uniting mechanism which travels lengthwise the machine. The lower gripper bar a has a relatively unyielding grip while the upper bar has a relatively yielding grip, so that when acted upon by the thread drawing mechanism the loose ends, which are held by the upper gripper bar will yield to the tension of the drawing mechanism and are free to be drawn into any desired position.

The upper gripper bar carried in the clamp pieces a is of similar construction to the lower gripper bar a differing only in that its hold upon the warp threads is not so tight but that the threads may slip through the same when pulled by the thread drawing mechanism, thereby providing the nec-' essary slack while leaving the thread end still held by the clamp. The upper gripper bar may be, if desired, similar to or corresponding in'function to the upper gripper disclosed in the patent to Sherman at al., No. 255,038.

Inthe operation of the machine the uniting mechanism is carried by the traveling carriage C (Fig. 2) lengthwise the machine and on suitable guides between the two opposing banks of threads. The carriage is fed at the desired speed by means of the lead screw 0 engaged by the split nut 0 upon the carriage, the handle 0 (Fig. 3) being employed to throw the carriage out of gear when desired by spreading or opening the said split nut.

The lead screw 0 is constantly driven through the gears 0 (Figs. 1 and 18) engaging the pinion 0 The latter in turn is driven by the gear 0 which engages with the pinion 0 upon the main drive shaft (Z. The shaft 0 carrying the gears c and 0 is mounted upon a swinging arm 0 and pivoted upon the main drive shaft (Z near the end thereof, (the left-hand end thereof, viewing Fig. 1), and adapted for adjustment to different positions to permit the substitution of other gears differently dimensioned from the gear 0 so that a reduction or increase in the speed of the feed screw may at any time be secured by substitution of a single gear.

The main drive shaft (Z carries at its opposite end (Fig. 1) a friction clutch D, the loose member of which maybe thrown in and out by the shipping lever (Z which can be thrown at any position along the machine by means of the overhead shipping rod d Two rotatable shafts e, e extend lengthwise the machine on either side of the central plane thereof, each supporting and holding in position one of the two opposite series of warp threads, the unseparated sheets of which are partially wrapped about their respective shafts. These shafts are removably journaled in the frame pieces at the end of the machine so as to be readily removed after union of the warps is completed to facilitate withdrawal of the united warps from the machine. The shafts e, e are given opposite rotary movements 'by the intermeshing gears e c (Fig. 17) and the train of beveled gears 6 the latter being driven through the inclined shaft 6 the beveled gear 6 and .the intermeshing beveled pinion 6'' fixed upon the main driving shaft d. Slidably mounted upon each shaft 6 (Fig. 2) is a device F which is adapted to select threads singly from the unleased unsepa-rated warp sheet being provided with a tapering nose 7, preferably corrugated for a portion of its length as shown in Fig. 2 and a threaded or screw portion f with an intervening cylindrical portion f. The selecting and separating device has a feather or key fitting a seat or keyway extending lengthwise the shaft 6, (see Fig. 2") so that it may be rotated by the shaft while being propelled and guided lengthwise the same. A standard f upon the carriage 0 having a pair of arms 7, i engages a portion 7', at the end of the selecting and separating device and causes the latter to slide lengthwise the same to correspond with the travel of the carriage G. Since the warp threads pass over the shaft 6 when the warp is placed in position, the advance of each selecting and separating mechanism causes the threads of each series first to travel upon the inclined nose f and, under the resulting increased tension, to be stroked by the corrugations when the inclined nose is provided therewith into a position of parallelism and passed over the cylindrical portion f. There they are engaged by the screw portion F, the advancing lip of which singles out each thread and selects it from the remainingones, the continuation oi the thread of the screw or worm portion then acting to move the selected thread along and further separate it, presenting it at the proper time and place to the action of the thread drawing device. The selecting lip referred to is formed where the groove or thread of the screw cuts through the slightly raised shoulder f at the end of the screw portion f and such raised shoulder bears against and moves across the edge of the sheet of un separated threads, the lip acting to pick oil the threads one by one as the rotation of the shaft 6 causes it to cut through the plane 01": the threads. 'The screw thread extends for a suficient distance to hold separated a series of the threads prior to their engagement by the thread drawing device so that the operator is enabled to check the accurate operation of each selecting and separating screw prior to the taking of the thread by the thread taking device.

A swinging member 1 is mounted upon each arm 7 and carries the tension finger g to hold the threads down into engagement with the selecting and separating de vice and particularly with the screw portion thereof, suitable downward pressure of said tension finger being provided by means of. the adjustable tension spring 9 in general, the operation of the nniting mechanism. in the form in which we have illustrated it is as follows: The carriage being fed with its thread drawing mechanism into alinement with corresponding threads in the two opposing warps, suitable and herein separate thread placing devices are caused to move forward to engage the said threads to draw them across each other and across the central plane of the machine and into substantial parallelism, where they are then. acted upon by appropriate uniting or thread joining mechanism. The free ends of the threads are then severed and the uniting mechanism, which herein consists of means for twisting and cementing the thread ends together, is caused to act. A positioning device, which has previously advanced to assist in maintaining the severed thread ends in appropriate relation to the uniting mechanism, seizes the united threads and lifts the same over and upon a guard or shield which travels with the carriage. In the meantime the carriage has advanced and the mechanism is now in a position to repeat the operation upon the next adjacent pair of threads.

The thread placing devices are best shown in Figs. 2 to 5 and 9 and 10. Except for the 10 'ation of the parts which permit the thread drawing mechanisms to move oppo sitely across the central plane of the machine without interference (see Fig. 9), they are substantially the same. Each comprises a needle h secured to the rocking bar It, the latter being connected by the link It to the cam lever h Each rocking bar 71 is supported by and movable with its lever arm 72, pivoted at h and actuated by the grooved cam it. (Figs. 3 and 4.) The two cams in their two extreme positions are shown in Figs. i: and 5.

These cams, as well as all the other cams and driving mechanism operated by the driving shaft (Z, (Fig. are carried by the carriage C to travel therewith, but are keyed or feathered to the shaft a to be turned thereby while sliding thereon. lVhen the cams are turned to the position shown in Fig. 5, the lever arms h assume the position shown in Fig. 9, and the springs h, which are secured to the links 7L2 pull the needles h into a substantially horizontal position where they are positioned each to grasp its appropriate warp thread on the reverse movement of the lever arm. As the cams move to the position shown in Fig. i, the lever arms each cross the central plane of the machine, the needles drawing their attached threads with them into the position shown in Fig. 10. As each lever arm reaches that position the cam lever it engages the adjustable screw 72. to cause the needle to sweep downward and draw its attached thread end down toward a horizontal position over and across the stationary rest pin 7v on the opposite side of the carriage. The rest pins (one of which is shown in side elevation in Fig. 2) are mounted in. the upper end of a. standard rising from the carriage base, and are of relatively short length, so that the lever arms 71. in their movement from the position shown in Fig. 9 to that shown in Fig. 10, do not engage therewith. The relative location of these parts is clearly shown in side elevation in Fig. 2.

Looking at the machine laterally, the needles operate in av plane adjacent the face of the vertically reciprocating friction pad Z (Fig. 2), so that the threads are drawn down by the needles and across the face of the said pad. Cooperating with the pad Z is a second pad Z, carried upon the face of a cement receptacle I which is kept filled with some suitable cementitious material. The two pads are faced with any suitable ma terial, which, however, is preferably of a somewhat absorbent as well as yielding nature and the face of the pad Z is kept charged with cement from the attached rcceptacle through any suitable system of capillary ducts. The two pads are recipro cated vertically by appropriate cams 7" and Z", driven by the shaft (Z, the pad Z having a rectilinear movement, but the pad Z, when separated position shown in Fig. 13.

lVhen the threads reach this position, the

. free ends which pass from the needle over and about the thread separating mechanism are caused to be severed. (See Figs. 6 and 7.) This is accomplished by two cutters adapted simultaneously to advance for severing the two opposite threads. Each cutter consists of the stationary cutter jaw m (Fig. 6), and the pivoted jaw m, the latter normally held open by the spring m Each jaw is carried upon an upright arm m attached to the double crosshead m sliding upon the guide rods m and adapted to be reciprocated to advance or retract the cutters by the bell crank lever m oscillated by the cam rod m cam roll m and cutter cam m After the threads have been drawn down as described, the cutters advance to include between their jaws the upper and free ends of the drawn and positioned threads as shown in Fig. 10. Further advance brings the heel m of each movable jaw against a stationary pin m causing a depression of the fore-part of the jaw and the severance of the thread (Fig. 6). The cutter cam m (Fig. 8) has a single point so that the cutter mechanism is caused to ad- Vance once during each cycle of operations and sever the thread and then immediately to retract.

Since the threads are drawn through the yielding clamp they are placed across the joining pad without substantial tension and without any marked tendency to snap away from the position in which they are placed when the threads are severed. The severing devices however are so timed that the severing of the threads is followed almost 'immediately by the action of the rubbing pads thus giving the severed threads no opportunity for displacement.

In the meantime, moreover, suitable positioning mechanism has advanced toward the threads and this further assists in maintaining the threads,and particularly the severed ends,in suitable relation to each other and to the pads, and, also acts, after the union thereof, by twisting, rubbing and ce-.

menting, to lift the threads away from the pads and over an appropriate shield or guard. The positioning mechanism consists of a pair of forked positioning arms n, (Fig. 13), each of which has appropriately shaped elliptical movement of the positioning jaws 0t carrying them from a position shown in Fig. 11 into a position where the threads finally enter the angle of the jaws and therefore assist in holding and positioning the threads while the union is being eiiected by the friction pads. The positioning mechanism continuing its movement moves to a position shown in Fig. 12, where the united threads are seized, lifted up and over the pad I, the pad I having been previously depressed down and away from its effective position. The positioning mechanism neXt moves to the position shown in Fig. 13, where the threads have been deposited over the upturned point of the shield 0, which extends over the mechanism at the rear of the carriage C thereby permitting the same to travel under the shed of united threads without interference therewith.

The cams which effected the vertical reciprocation of the two pads are provided each with two points (one only of said cams being shown in Fig. 15) and are arranged relatively to each other so that the elevation of one is accompanied by a depression of the other, the result being that at the appropriate time the drawn threads are rubbed between the alternately raised and depressed cement coated surfaces of the two pads and are then freed by the depression of the pad Z ready to be lifted by the positioning mechanism.

In the meantime the carriage has been advancing and has reached a position in alinement relatively to the next adjacent threads of the two warps so that another cycle of operation, similar to that described, can now be effected and the next pair of threads united in the same way.

It will thus be seen that as the carriage progresses lengthwise the machine between the series of threads in the two warps, which threads are held distended in mass, the separating mechanism acts to single out and separate the individual pairs of threads and that each individual pair, when the appropriate position of alinement is reached, is drawn into the position of engagement with the uniting mechanism, the free ends of the threads severed, the union effected and the united threads withdrawn from the uniting mechanism. This operation proceeds step by step until the entire series has been united, when the entire series of united threads may be withdrawn from the machine. F or this purpose the over head parts of the machine are made readily removable.

Herein provision is made to permitthe uniting mechanism to act upon the individual threads of each series to be united irrespective of a difference or irregularity in spacing. In the form of separating device shown, it is desirable for the effective action of the selecting device that each warp thread engage the lip of the screw at substantially the same angle. In practice, however, commercial warps are not only irregularly spaced. but the two warp sections to be joined are seldom of the same width and spacing. If one has already been in the loom it will usually be narrower and more closely spaced than the other. If both are maintained stationary, therefore, the advance of the uniting mechanism will cause the threads of one warp to bear a varying and an increasingly different relation to the selecting device from the threads of the other warp.

Whether this specific mode of thread separation is employed or not, or whether the alinement of the threads is considered with reference to some other part of the uniting mechanism which acts upon them, it will be evident that some approximately certain relation must be maintained between the warp threads and the uniting mechanism considered as a whole.

One feature of our invention is to provide means for correcting this variation in aline ment arising from difference in the width of the warps and to adaptor compensate the action of the operating mechanism to the different or irregular spacing of the individual warp threads. Obviously, the adjustment of these several elements,the two warps and the uniting mechanism, might be effected in various ways as for example by correctly proportioning the advance of the uniting mechanism to the width of one Warp and then adjusting the position of the other warp to suit the already corrected alinement of the uniting mechanism and the threads of the first Warp.

The actual widths of the warps vary so, however, that this would necessitate a fresh adjustment of the feed of the uniting mechanism for every new width of warp, and we therefore prefer to select a feed for the uniting carriage which is only approximately that desired and preferably a little less than is required to advance it at each cycle of operations into a position of alinement with respect to the shorter of the two warps. \Ve then employ suitable mechanism to d1flerentially adjust the position of each warp carriage to bring the individual threads thereof into appropriate alineinent If the advance of the uniting mechanism is less than that required there will be simultaneously given a slight differential movement of the narrower warp in the opposite direction, and a somewhat greater movement of the wider warp also in the opposite direction, the movement being designed in each case to bring the appropriate threads to be united into the desired relation with each other and with the uniting mechanism. I

Referring now more particularly to the means by which this is accomplished in the illustrative embodiment of the invention, the two warp carriages carry fixedly secured thereto appropriately toothed racks p and (,7 (Figs. 1 and 17) adapted to engage with corresponding worms 1) and The worm p for one carriage is at one end of the machine and the worm for the other is at the opposite end of the machine. A rotary movement of the worm in either case will effect a longitudinal feed of the corre sponding warp carriage and this is designed in each instance with relation to the total length of the warp to be sufficient to bring the individual threads of the warp into proper relation to the uniting mechanism. The 'worm p is given a step-by-step movement of an adjustable amount at every rotation of the lead screw by the following means: Referring more particularly to Figs. 19 and 20, adjacent the face of the worm p is carried the knurled or finely toothed disk 39 rigidly secured to the worm and adapted to be engaged for movement of the worm by the gripping pawls p". The latter is secured to the pin 7) loosely journaled in the swinging arm 72", the op posite end of the pin being secured to the stop lever 10. The lever 7) therefore has swinging movementindependent of but upon thearm 12", such movement being limited in one direction by the adjustable stop screw 1) carried by the arm p. Rotation of the lead screw brings the point of the cam 7) against the end of. the adjustable contact screw p carried by the stop lever 39, and this tends to swing the heel of the latter away from the stop screw bringing the pawl into gripping contact with the toothed periphery of the disk p The movement of the swinging arm 10', which is loosely journaled on the stud p is slightly opposed by friction created by the spring [1 so that the stop lever swings with relatively greater freedom than the arm. When the pawl grips the disk however further movement of the cam swings the stop lever, swinging arm and pawl as a unit *ausing movement of the worm ,1). As the cam drops away from thescrew p retraction of the swinging arm is caused by the tension spring 77 (Fig. 17) attached to the stop lever and therefore causing first a release of the pawl and then a return of both the arm and the stop lever to the position shown in Fig. 19 against the stop pin 19. By adjustment of the contact screw p or the stop screw or both, the effective movement of the pawl 12 may be varied so as to give a movement to the rack and the attached warp carriage to any desired extent within certain limits, and this adjustment will of course be made with reference to the the length of the warp and the differential movement thereof required.

It will be observed that excepting when the cam is acting through the pawl to move the worm and the warp carriage the pawl is out of engagement with its toothed disk 'and the carriage is free to be positioned by hand if desired. lVe have here provided means for -manually positioning the carriage and this comprises (Fig. 1) the pulley 7" fixedly secured to the worm 7) connected by a band or belt 9" with the pulley r at tached to and rotatable with a rotary adjusting rod 7' which is journaled above the machine and may be manually moved by the operator in whatever position he may be. This compensating adjustment, it will be seen, may be effected at any time and independently of the automatic feeding mechanism.

Referring now to Figs. 18, 21 and 22, more particularly, the worm g is operated in substantially the same way as that already described in connection with the worm p. A toothed plate 9 pawl and other parts are provided which are in substantial correspondence with the similarly lettered parts associated with the worm 39'. Instead, however, of a cam operation, movement of the pawl g and the swinging arm 9 and stop lever Q6 is effected by the reciprocating rod which is adj ustably secured (see Fi 18) to the rocking lever 51 the latter pivoted at and adapted to be reciprocated to and fro by the cam fixed to the lead screw, thereby to cause the reciprocatory movement of the pawl g and the differential movement of the corresponding warp carriage. The length of the stroke of the pawl g obviously may be adjusted by changing the position of attachment of the rod 9 and the rocker lever It will thus be seen that we have provided for the series of warp threads a differential and a compensating movement capable of delicate adjustment to suit the individual requiren'ients of each warp and to maintain them in accurate alinement with the continually advancing thread uniting mechanism.

Since the warps may be adjusted to crowd the foremost unseparated threads thereof against the leading end of the thread selecting and separating device, the latter acts to supplement the described mechanism in correcting or compensating for localized irregularities in the spacing of the individual threads of the warp. As they are pushed upon the inclined nose of the selecting and separating device they are brought into an approximately parallel relation and under an increasing tension so that when they encounter the selecting lip they tend to lie closely arranged and in a flat, stretched sheet.

Our invention is not limited to the specific details of the embodiment here described or to the specific means herein described for securing the adaptability of the action of the thread joining mechanism to the irregular or different spacing of the warp threads, but is susceptible of extensive modification and departure from the construction and arrangement of parts here shown without departing from the spirit thereof.
