MACHINE FOR REREEDING WARP ".LIiIR-IEADS Application filed April 1, 1.915, Serial No. 18,596.
T all whom it may concern:
Be it known that we, J AMES FRANK MAT- rrrnws and EDGAR F. HATI-IAWAY, citizens of the United States, and residents of Fall River, Massachusetts, and Boston, Massachusetts, respectively, have invented certain new and useful Improvements in Machines for Rereeding Warp Threads, of which the following is a specification.
Our invention provides means whereby the work of re-reeding a warp may be accurately, quickly and cheaply done, and, so far as we are aware, provides automatic mechanism for that purpose that is broadly no el. The principal part of the work of drawing-in is that of putting the individual threads through the eyes of the several harnesses that may be employed, and, in some instances, also through the apertures of the stop-motion drop-bars that may be emplo ed.
e-reeding, as it is called in the mills, provides a method whereby in case of damage to the reed orother cause making rereeding necessary, the main portion of the work already done, in drawing-in the warp, is preserved. Generally, although not always, each dent of the reed (the dent being the space between the parallel metal members which are called splits) carries a plurality of threads; and in re-reeding, if the organization of the warp in the old reed can be preserved, the plurality of threads in each dent of the old reed may be transferred by a single operation to a corresponding dent of the new reed, and thus a relatively large number of threads may be quickly handled.
Broadly, our invention provides means whereby this may be automatically done, the threads being transferred accurately from the old reed to the new reed, and preferably in such manner that the entire group of threads in any given dent of the old reed is transferred, through a single operation,
said means also having the additional func'- tion of engaging the thread or group of threads in each dentof the old reed and presenting said thread, or group of threads,
at a single operation into the corresponding dent of the new reed.
One of the detail objects of our invention is to provide a form of machine for this described purpose which is portable and designed for being properly positioned upon the loom so that the work of re-reeding may be performed upon the loom without removing the warp and the rest of the weaving equipment from the loom; but, of course the re-reeding operation may be performed apart from the loom. Power for driving the mechanism may be transmitted to the actuating shaft bv any suitable or convenient mechanism.
. In the accompanyingdrawings we have illustrateda convenient form of mechanism embodying the principles of this invention,
in which:
Figure 1 is a side elevation partly in section showing the relative dispositions of the two reeds and the transfer member.
Figure 2 is a detailview in vertical sec-' tion showing the means for mounting the movable transfer member.
Figure 3 is a plan view of the same apdirectly upon the loom, and to that end is.
mounted on the base or frame 0 whose forward end rests upon the breast beam wfland whose rear end rests upon the transverse beam of the lay m, as shown in- Figure 7.
in socket c in said standards.
When the device is thus placed on the loom the warp threads g still remain in the harness and in the reed a. The free ends of the warp yarns are loosely clamped together by any suitableform of clamp a faced With textile fabric or other suitable material and yieldingly pressed together by compressing springs a The clamp is put on before the warp ends are severed from the cloth already woven so as to preserve the proper order and arrangement of the warp threads. The reed a is carried over an elevated horizontal rod'a and laid upon parallel smooth horizontal supporting bars or tracks a which are themselves supported by upright standardsc on the base 0. The clamp a hangs As the threads are gradually withdrawn from the clamp, the latter settles to the bottom of the sockets 0*.
The yarntransferring member comprising the hook or needle 9 suitably supported and; actuated, as will be hereinafter ex plained, is mounted on a standard 6 carried by the transversely movable carriage 6 so that the transfer membermay start at one end'of. the reed and be shifted step by step to engage and re-reed each successive warp thread across the width of the loom.
The ends of the warp threads 1] being held in vertical position by means of the cross bar a and the clamp (4 the carriage is shift-- ed to one side in position to bring the hook needle 9 into alinement with the warp threadsat the extreme right of the reed a. The second reed b which is to receive the warp threads is suspended from a shiftable carrier rod 6 freely supported upon rollers c (Fig. 4) carried by the standards 0 mounted on the carriage e by means of depending arms 6 provided with locking or retaining springs 6 The reed b is suspended between the rear end of the needle supporting bearing 9* and the vertical portions of the warp threads 3 The principle of action is that the hook needle 9 is passed through the appropriate dent of the reed b which is to receive the first or extreme right-hand warp thread and moves backinto position to engage said warp thread and draw it forward through said reed dent, as indicated in the diagrammatic Figures 8 and 9'. This operation is repeated with-each successive dent and warp thread until all the threads have'been drawn out of the clamp a and the reed 0: anddrawn through the reed b.
To efficiently and reliably perform this operation we employ means for supporting the two reeds in proximity and with their splits lying in substantially parallel vertical planes, and .a coordinated reciprocating transfermember or needle alined with a device for opening successively the dents of the receiving reed for the passage of the transfer member into position to engage the appropriate warp thread or group of warp threads contained in the corresponding dent of the warp-containing reed, the delivery of the warp threads to the transfer member being accomplished by a device which acts in co-operation with the reed itself to engage the appropriate thread or group of threads in their containing dent, and position them to engage the barb of the transfer member or needle. The mechanism also embraces a means for feeding the carriage c which car ries the transfer member progressively step by step across the loom along the reeds, and to secure perfect alinement each reed is supported so as to be freely movable in the direction of its length or across the loom. to accommodate itself to the successive position of the respective reed openers. Provision is also made for removing each warp thread from the hook after it has been drawn through the second reed, which action is effected by means of a movable stripper member working transversely to the path of the hook needle. The reeds are mounted on their respective supports so as to be easily capable of longitudinal shifting or move ments for compensating purposes as will be hereinafter explained.
o will now explain in detail the mechanical devices or movements illustrated in the drawings for carrying out the objects of the invention. The old or warp-containing reed is mounted loosely on the tracks a. so as to permit the longitudinal compensating or shifting movement requisite to maintainthe successive dents of the reed in proper alinement with the successive positions of the transfer needle g, it being understood that thereeditself forms an element in co-operation with thc yarn-delivering element to position the successive warp threads or group of threads where there is morethan one thread to the dent, to the transfer needle. In the specific form of the invention shown.
the device for maintaining the reed in prop er relationship or position is also employed for engaging and presenting the warp threads properly to the transfer needle it self. This comprises a forwardlyrotat'ing cam d secured'to a shaft (Z mounted in a swinging supporting bracket driven by a horizontal transmission shaft d Fig. 3), by mitre gear connections (Z d. This cam 03 is slotted in a substantially radial direction with the two adjacentedges slightly offset in an axial direction so that the cam cam to work its way into each successive dent of the reed to maintain proper alinement of that dent with the transfer needle,-
but also enables the cam to engage the thread or threads contained in the successive dent itself. The aforesaid split of the reed acts to hold the warp thread to be seized slightly away from the face of the cam so as to be properly engaged by the hook or barb of the needle which is turned toward the cam. It will therefore be seen that the cam acts through each successive split of the reed to present the adjacent segregated warp element to the needle. The shaft d is driven by a mitre gear connection from the hori zontal transverse shaft (Z which is concen tric with the axis of the swinging bracket or arm d? and is itself driven from the vertical shaft (Z by'another mitre gear connection. In order to prevent the weight of the cam from resting upon the reed, we provide an adjustable stop screw d tapped into the bracket 05 in position to engage a stop shoulder (Z formed on the bearing bracket of the shaft d which is carried by the standard e on the carriage This arrangement permits the vertical adjustment of the opener cam d in relation to the reed a and also permits the cam to beswung up entirely free from the reed into inoperative position indicatedin dotted lines in Figure 1 whereit is detachably held by means of the retaining arm or detent is which is pivotally mounted upon the carrier rodb The opener cam for operating on the receiving reed acts on a similar principle so far as concerns the positioning of the new reed, but owing to the vertical position of the reed b, there is no .need of mounting it on a swinging bracket. This opener comprises an off-set slotted cam f similar to cam d but rotated in the opposite direction to the cam' d by its supporting horizontal shaft f which is rotated by a mitre gear connection with vertical drive shaft 3, the bearings for which are carried in the vertical standard or bracket 6 branching from the standard a.
The transferring hook or member 9 is secured in a cylindrical socket or holding member 9* which is mounted to slide back-.
ward and forward in the horizontal bearing sleeve 9 carried by the bracket (2 mounted on the carriage e. The bearing sleevev g is provided with a partly spiral cam slotg through which projects a pin or stud 9? secur'ed to the socket member or holder 9 so that as the needle approaches its advanced position when adjacent to the cam CZ, the transferring member whose hook up to that time has been in the vertical position, is given a quarter turn toward the adjacent warp thread in order to engage the same.
The warp yarn, by the complete rotation of the cam 01, which is also a yarn-positioning member. has been transferred from the left-hand side of the cam (Z to the righthand side, in close proximity to which the needle hook travels. By the action described, the hook and the warp threads are brought into proper operative relationship to allow the warp thread to be engaged by the hook. Moreover, the cam, by separating the thread or group of threads contained in a given dent and shifting it to the other side of it self, prevents the hook from seizing a thread of the next succeeding dent.
The hook now travels back, drawing with it the yarn end through the second reed 6. After the hook has passed back to the front side of the reed b, a swinging stripper member 0 provided with a thin hook-like blade at its forward end, is swung across the thread between the hook and the reed in order to disengage the yarn end from the hook so as to leave the hook free to advance into position to engage the next warp thread.

The opener or cam f is arranged in the same vertical plane as the needle 9 and acts as a spreader to open the appropriate dent in the reed Z; to allow the needle to pass through. The mounting of the reed on the transversely shiftable carrier rod 6 allows the reed to accommodate itself perfectly to the position of the opener and of the needle incasethere is any slight variation'between the spacing or intervals of the dents and the step by step movements of the carriage transversely of the loom.
Power is applied to the actuating mechl anism by means of the handle h mounted V .eccentiucally on the wheel 71 secured to the horizontal shaft 21 The pin of the handle hi passes through a slot in the lever 71 which lever is connected with the upwardly extending slotted arm or lever h by means of the hub 71 In the slot in the upper arm 72. is a pin it secured to a sleeve Q12 (Fig. 2) which is rotatable upon theneedle holder but is held against longitudinal movement with relation to the needle holder. The pin it extends through a. gnideslot 5/ formed in the bearing sleeve 9.
From the shaft 2' are actuated all the other trains of mechanism for advancing the car:
riage intermittently, actuating the devices d and f, and stripping the yarn from the hook. Toadvance the carriage, thereis secured to the base or platform 0 a transverse rack.
bar 0 which forms one of the guides for the carr age c and also has engagement with the pinion 1"c'arr1ed by the vertical shaft 7' mountedv in the bearing sleeve or bushing which is clamped in the bed of the carriage by nut r*. The ratchet arm 1- carrying at its frontend a spring pressed pawl r and slotted at its rear end to rest astride the shaft 11 is provided with a pair of anti-frictimi rollers i which engage opposite sides of the rotating cam 11 which is fixed to the shaft 2' so as to impart a reciprocatory movement to said ratchet arm 0. The front end of the arm 7 issupported and guided by an oscillatory arm or lever 2' mounted at the top of the shaft 7 above the ratchet wheel 7 To provide for the pawl engaging a greater or less number of ratchet teeth ateachstroke, we employ an adjustable hood or pawl stripper 7' which is mounted on the sleeve bushing r so as to be adjustable cir cumferentially into position adjacent to the pawl soas to keep the pawl from engaging any more of the ratchet teeth than is desired. This permits the step by step travel of the carriage to be varied according to the coarsenessor fineness of the reeds.
The stripper 0 is slidinglymounted in a swivelled sleeve 0 and has at its left-hand end a sleeve a engaging an eccentric pin a on the wheel a which is compounded with the spur gear 11- meshing with the gear a. The gear a is driven by means of a mitre gear connection 2' from the main drive shaft i.
The actuating or driving mechanism for theopeners-or cams (Z and f is arranged as follows: On the shaft 11 is secured a disk i carrying a projecting pin i in position to enter and engage on successive revolutions one of a series of six radial grooves m formed in the adjacent face of the over-lap ping star wheel m so as to produce one-sixth of rotation of said wheel for each revolutionof the drive shaft 2' the wheel m remaining. stationary during the period that itis out of engagement with said actuating pin i. The star wheel m is thus held stationary by reason of engagement of the locking segment 71 with one of the recesses m of the star wheel, said locking segment being fixed to and concentric with the disk '5 On the shaft of the wheel m is secured a spur gear m meshing with the pinion m which transmits intermittent rotation to the shaft m through mitre gear connections. On the rear end of the shaft m is secured a mitre gear m inter-meshing with mitre gear m which is secured to the vertical shaft f By means of spur gears f 03 the same intermittent rotation is transmitted to shaft 03 operatingthe opener d that shaft f has in operating opener f.
The cams and other working parts are so co-ordinated that the carriage e is shifted through the ratchet 1' when the needle 9 is retracted toward the front end of its socket and is entirely withdrawn from. the vertically hung reed Z2. At this stage the arm h.
acting upon the needle holder 9 serves to advance the needle just as the cam f is rotated into position to open the dent of the reed b in line with the advancing needle. The cam f, being radially slotted with the adjacent edges of the slot off-set, acts to disengage the cam from one wire while engaging it with the next one, the cam being of sufficient thickness to open or widen the interstitial space or dent to allow the needle to easily enter and pass through into position alongside the cam (Z whose movement is coordinated to shift one thread or group of threads from the left to the right-hand side adjacent to the hook of the needle, as al ready described. The needle 9 is then retracted, and as it is retracted the hook is turned to vertical position still holding the thread so as to pass easily through the reed b. After being retracted clear of the reed, the stripper member or hook 0 swings across the thread and pulls it out of the hook of the needle. By reason of their engagement with the respective wave-cams d andf, the reeds a and b will be accurately positioned for each successive traverse of the needle.
The supplemental guide or support 9 (Fig. 6) may be located close to the reed just in advance of the shaft f which carries the opener cam f in order to form a support for the needle in its advanced'or operative position. This guide member consists of a plate 9 having a key hole slot 9 to allow the passage of the needle and hook when the hook is vertical and the slot is left open at the bottom to enable the warp thread to be removed from the guide plate after the needle has been retracted until the hook has passed entirely clear of the guide plate.
The cams (Z and f each serve a two-fold purpose. They both serve to correctly correlate the reed dents with the needle at each successive operation and to maintain them in proper correlation while the needle does its work by reason of the fact that said cams have an intermediate rotation as previously described. The cam al also serves through the medium of the reed which it positions as an agent in presenting the yarn to the needle. The cam 7 acts also as an expander or opener for spreading-apart the splits of each successive dent to facilitate a passage of the transfer member.
In some classes of work it may be desirable for the attendant to advance the carriage more rapidly than the regular pace of the machine set by the automatic mechanism. To enable this to be done, we have provided the pinion shaft r with a hand wheel t adapted to be grasped by the. operator and turned to any extent desired. This is advantageous also for setting the carria e quickly to the proper position to begin its normal. automatic operation.
