LOOIVI FOR WEAVING TUFTED'PILE FABRICS.
SPECIFICATION forming part of Letters Patent No. 654,363, dated J' uly 24, 1900.
Application filed October 4,1898. Serial No. 692,597. (No model.)
To all wtom may concern:
Be it known that we, HALcYoN SKINNER and FRANK H. CONNOLLY, citizens of `the United States, and residents of Yonkers, in the county of Westchester and State of New York,have invented new and useful Improvements in Looms for Weaving Tufted Pile Fabrics, ofwhich the following is a specification.
This invention relates to improvements in looms for Weaving tufted pile fabrics, and
more particularly to looms for Weaving modotted lines.`
quette77 carpets whereby the weaving of fabrics of considerably greater width than has hitherto been feasible is accomplished.
A practical embodiment of our invention is represented in the accompanying drawings, in which- Figure 1 is a front view of the left half of the loom. Fig. 2 is a front view of the right half of the loom. Fig.'3 is a vertical section from front to rear in the plane of the line 3 3 of Fig. 2. Fig. 4 is a partial vertical section from front to rear in the plane of the line 4 4 of Fig. 2. Fig. is a partial vertical section from front to rear in the plane of the line 5 5 of Fig. 1. Fig. 6 is a partial vertical section from front to rear in the plane of the line 6 6 of Fig. l. Fig. 7 is a partial top plan View showing the shuttle and the means for drawing the weft-thread up into proximity to the fell in position to be engaged by the lay-beam. Fig. 8 is a top plan view of one of the spoolcarrying arms, showing the ends of two adjacent spools in position therein. Fig. 9 is a side view of the same. Fig. 10 is a front view. Fig. l1 is an enlarged detail view for showing more clearlythe parts which operate the nippers. Fig. 12 is a View of a portion of the parts shown in Fig. 11, showing the nippers in their raised position about to grasp the tufts. Figs. 13, 14, and 15 represent detail views of the jaws of the nippers in different positions which they assume. Fig. 16 is an enlarged detail section representing the comb and its operating parts, the comb being represented in its forward upper position in full lines and in its forward downward position in Fig. 17 is a top plan view of a portion of the same. Fig. 18 is adetail vertical section of the comb and a portion of its operating mechanism, the comb being shown in full lines in its backward and downward position and in dotted lines in its backward and upward position. Fig. 19 is a partial front view of the same. Fig.` 20 is an enlarged detail top plan view of a portion of the tuftsevering shears and a portion of vtheir operating mechanism, the'shears being shown in their open position in full lines and in their closed position in dotted lines.

Fig. 23 is an enlarged detail' side View of the chain-reversing mechanism. Fig. 24 is a front View ,of the same; and Fig. 25 is a view similar to Fig. 23 with a portion of the controlling-disk nearest the observer broken away, the partsy being shown in the reverse position to that shown in Fig. 23.
A designates the main frame of the loom; B, the breast-beam; B', the web-supporting plate, and B2 the take-up roller.
C designates the stationary shuttle-race, and D a set of heddles. operating the heddles and shuttles has not been shown in the accompanying drawings, as it is believed that it would unduly complicate the same.
E designates the main drive-shaft, which is mounted in suitable bearings and extends transversely across the loom at a point near its base.
F designates the lay-beam, which is mounted to rock back and forthv on a cross-shaft f, which lay-beam is operated by two operating mechanisms, each of which consists of a cam f on the drive-shaft E, which cam engages a roller f2, carried by a rocking arm f3, connected to the lay-beam by a short rod f4. The cam f is so constructed that it will impart to the lay-beam F three forward-and-backward movements during one revolution ofthe driveshaft E.
The chains G, constituting spool-frame-carrying means, are arranged in pairs.` In the present instance we have represented three pairs of chains located side by side. These chains G are endless and are driven by sprocket-wheels g, mounted on a cross-shaft g', carried by the loom. A plurality of idlersprockets g2 are located in any suitable position above the loom-frame thatV the chain The mechanism for IOO may be run horizontally back and forth for any desired distance, the number of idlersprockets varying according to the length of the chain. Guides g3, presenting each a horizontal flange g4, supporting the outermost chains G of the outermost pairs of chains in the lower run of the chains and their guides gSX, having opposite ilanges gm, are located at a point where a chain of one pairof chains runs close to the chain of another pair of chains, the flanges g4 of the guides 93X supporting the chains at intermediate points. These flanges receive upon them in the lower run of the chain substantially right-angular lips Q42, extending from arms gl, connected with the spool-frames g5. Points or projections g, extended from these lips substantially at right angles, enterspaces betweenthe links of the chains. The flanges g4 and g4X support the frames and constitute a track over which they are free to be slid by the chains in the lower run of the chains near the positivelyactuated shaft g'. These guides g3 permit the use of a very long spool-carrying chain without takingup too much room. If it were not for the use of these guides, the chain would have to be fed directly from one of the idlersprockets g2 to the drive-sprocket g, as the position of the adjacent ends of the spool-carrying frames is such as to preclude the use of sprockets engaging the outer sides ofthe said chains.
Each pair of chains contains a series of spoolframes having each a spool, and each pair of chains has a like number of spool-frames, and
the chains are so applied to their actuating means, represented as shafts and sprocketwheels, and so timed in their movement that the separate spool-frames of each pair of chains are in alinement with the spool-frames ofthe other pairs of chains, said alined spoolvframes constituting a row of spool-frames parallel with the fabric being woven. In the present instance three spool-holding frames are located in each row and the rows are spaced apart a distance equal to the length of the step-by-step movement ofthe chains G. Each of the spool-holding frames consists of a crossbar g5, having a pair of upwardly-extended end bearings g6 and a pair of curved arms g7, located near the ends of the bar. The arms gf" are extended from one edge of the spoolframe, and they cross the axis of rotation of each spool at a point between the headed ends of the spools. The arms g7 correspond in number 'with the chains G. The end bearings g6 are adapted to support the spindles of the spools g8, so that several spools-in the present instance three-are supported with their axes in alinement with each other, thereby doing away with the necessity of using a very long single spool and frame or a long frame with a plurality of spcols,which 'in either case Arequires the employment of means to prevent the sagging of -the axis of rotation of the alined spools which destroys the proper alinement of the tuft-threads. The arms glare curved thatthey may embrace the spools, and
their upper ends are represented as terminating (see Fig. 9) substantially above the axes of the spools, and the extremity of each arm has a horizontally-extended lip gm, provided with a prong g9,adapted to enter a space in the open links of the chains G. The lips g4? (see Fig. l0) overlap and ride on horizontal flanges g4 of the guide 98X, so that whenever a spool-frame is traveling in the lower run of the chain, as in Fig. 3, said lips rest on said flange and the frames are supported by the flanges, the chain resting'on the lips andin their movement by the chain-actuatin g devices sliding the lips over the flanges of the guides.
The guide shown in Fig. l0 is a double one,
it being located between chains of two pairs of chains; but the guide g3 shown in Fig. 3, it being located at the inner side of `the loomframe, has but one flange g4, as it supports but one chain of a pair.
Each arm g7 has pivoted upon it a suitable latch or pawl gw, which is acted upon by a suitable spring gmx. These pawls hook over the links of the chains entered by the projections g9 and connect the spool-frames with the chains to be moved thereby, said latches being turned aside and released from their engagement with the chains whenever a spool-frame is to be removed from a pair of chains.
A thread-guide gu* is secured to the crossbeam of the thread holding frame, which guide serves to separate the threadsinto tufts and hold them in position to be engaged by the nippers and severed by the shearing mechanism.
Each row of spool-holding frames is released from the chains G when the row reaches the position where it is to be engaged by the transferring mechanism by means of a series of tripping devices, represented herein as arms g, mounted on a cross rock-shaft Q12, which rock-shaft is operated-at the proper intervals by an arm Q13, having a connecting-rod Q14 leading to one arm of a rocking lever g, the other armof which is provided with a stud or roller gw, which is engaged by a cam g, carried by the drive-shaft E. The trippingarms g11 referred to when rocked forwardly serve to force back the pawls g1() on the arms gl, and thus release them from the chains G.
The transferring mechanism above referred to comprises a rock-shaft I-I, having a series of connected arms h keyed thereto, these arms varying in number according to the number of spool-frames, and usually there is one more arm than there are spoolframes. Each of these arms is provided with an adjustable plate 71,,having a notch or socket h2 for receiving two sides of one of the arms g7 at a point about midway between its ends, and a spring-actuated retainer h3, which Vengages a third side of each of the arms gl, wghereby the said arm is retained in its socket h extension h4, having at its free end a shoulder 71,40, (see Fig. 9,) adapted to underlie and ICO IIO
Each arm h is further provided with an partially embrace the spool-holding frame'. lare caused to overlap the straight cutting The extension h1 has a forward and rearward adjustment, as has also the plate It. The two arms 7L of the series,- the arms which are located between the outer arms, are provided vwith a plate h', having two sockets h2 (see Fig. 8) and two spring-'actuated arms h3, so that the said y arms may engage and support the arms g'l of two spool-holding frames. The transferring-arms h are raised at the proper intervals to receive one row of spool-carrying frames from the chains G, then lowered to bring the spools down into proximity to the fell of the cloth, where the tuft-threads may be grasped by the nippers and a portion thereof severed by the shearing mechanism, and the arms are then again raised to return the spool-carrying frames into engagement with the said chains. The means which we employ for imparting the said alternating upward and downward mo vements to the arms comprises a cam 71., (see Fig. 4,) carried by the drive-shaft E, which cam engages a stud or roller h6 on a rocking arm 717, connected to one of the arms h by a connecting-rod lts. Heretofore in'handling spool-frames a transferring device has been made to engage each end of each frame, and to handle these frames simultaneously in such old plan would require six transferring-arms. A loom, however, such as herein described to be practical must be capable of inserting and spacing uniformly all the tufts of each row of tufts, and consequently the contiguous ends of the spool-frames must nearly or substantially touch each other. To provide for this novel position of the end of a row of spoolframes and at the same time handle themas one rigid whole, we have had to devise the peculiar arms Q7', and also have devised one arm h to engage the contiguous ends of two alined frames, said arms cooperating to engage and move simultaneously the contiguous ends of the two frames in exact unison. As all of the arms h are keyed to the rockshaft H, the upward movement of one of the arms imparts a similar movement to all of them. The downward movement of the transferring mechanism is arrested by means of an adj Listing-screw b9, carried by abracket hw, mounted on one of the side uprights of the main frame A, which adjusting-screw is adapted to engage an arm h, projecting from the rock-shaft H.
We provide a shearing mechanism for severing the tuft-threads after their free ends have been engaged by the nippers and a por tion of the threads withdrawn from the spools, which shearing mechanism is constructed and arranged as follows: A pair of side arms t'project forwardly from and are keyed to a rockshaft I, located beneath -the rock-shaft H. Outer and inner movable cutting-blades 1"- @l2 are mounted i n bearings in the free ends of the side armst'. These cutting-blades are mountedge of the inner blade/i2 will `rest upon the top of the outer blade i. The cutting edge of the outer blade t" is of zigzag form, so as to produce a shearing cut upon the threads, thereby ensuring a clean severing of the said threads. Intermediate strengthening-arms @'s project forwardly and have their free ends in engagement with the inner cutting-blade t2. These arms t3 are arched, so as not to interfere with the regular action of the heddles D.
In operating the cutting-blades the inner blade 2 is first advanced into its foremost position and the outer cutting-blade is then drawn inwardly to the limit of its movement in that direction.
The means which we employ for operating the cutting-blades is as follows: A transverse bar i4 is mounted to slide in suitable bearings in the arms 'i i3, which bar is provided with a series of cams @5 on its front face, which cams are fitted to engage studs or rollers t6, carried by the cutting-blade @'2. One or more retracting-springs 'l'7 extend from the cutting-blade 122 to points on one or more of the arms t3. This spring holds the blade t2 at the limit of its inner movement except when the blade is forced outwardly by the transverse movement of the bar i4. This bar "i4 is provided with a rearwardly-extended cam-plate @'8,which plate is provided with an elongated groove i9. A forwardly and backwardly movable rod 1 is provided with an adjustable uprising pin or lug 11, which enters the groove if and serves to impart the transverse movement to the bar 4 as the rod @'10 is moved back and forth. i The outer end of this rod @'10 is provided with an elongated slot i12, within which is located a pin 13, carried by the outer cutting-blade t. The parts are so arranged that during the 'rst portion of the rearward movements of the rod 7110 the inner cutter-blade t2 is moved forwardly and during lthe latter portion of the rearward movement of the rod @'10 the cutting-blade t" is moved rearwardly.
The mechanism which we have shown for imparting the forward-and-backward movements to the rod @'10 comprises a rocking lever @'11, pivoted to an arm @'15, depending from one of the side arms QI. lever 11 is connected to the rod i111 and `its other arm is connected to a rocking lever 1116 by a rod 7117, the lever @'16 having a stud or roller @$18, which is held in engagement with a cam @'19 on the shaft E by a retracting-spring @'20.
The means which we employ for raising and lowering the cutting mechanism com- IOO One arm of the rocking prises a rockinglever 21, connected to one of i ed in planes at a slight angle to each other, so upon a plurality of adjustable arms @'25, hinged tov rigid arms @126, carried by the breast-beam that when the cutting edges of the said blades B; The adj listing-screw @'27 serves to raise or lower the free end of the hinged arm The limit of the' downward movement of the cutting mechanism is adj ustably limited by means of an adjusting-screw @'28, mounted in a bracket @'29, carried by one of the side uprights of the main frame A, which adjustingscrew is arranged to' engage an arm @'50, projecting from the rock-shaft I. After the limit of the downward movement of the cutting mechanism has been adjusted the arms 25 are adjusted so as to just touch the bottom of the outer blade, so that although the said blade may be made quite light it cannot yield when the cutting operation is being performed.
The mechanism for operating the nippers is located below the warp-threads and the nippers arenormally located below' the same, the jaws of the nippers being brought upward at intervals between the warp-threads into position to grasp the free ends of the tuftthre'ads when the spools have been brought down in proximity to the fabric. The nipperjaws are denoted byJ J, the jaw Jbeing movable toward and away from the jaw J. These jaws extend transversely across the loom, vand vtheir upper edges are cut to form teeth, which pass up between the warp-threads for engaging the tuft-threads. Thejaw J is supported in the free ends of the arms j, which are pivoted on a cross-shaft j', which crossshaft is carried by the free ends of arms L@2, keyed to a rock-shaftjs. The jaw J is hinged on a cross bar (i4, which is mounted in bearings j, projecting from the stationary jaw J. The jaws are held normally apart by means of a springj, extending from one of the tailpieces f, carried by the cross-rod l7'4, to a point on one of the arms j. These tailpieces L7'7 are provided with studs or rollers js, which are adapted to be operated by cams j. Each of these cams in the present instance consists of two parts, the cam part proper being extensible by means of an adjustingscrewy'10 along the other part ju. There are a number of these cams and they are all keyed to a rock-shaft f2, carried by the arms jof the. jaw J. These cams are operated for closing the jaws at predetermined intervals by means of a camj13 on the drive-shaft E, which cam engages a stud or roller j, carried by one arm of a rocking lever j, the other arm of which is connected with an arm jm, keyed to the shaft f2 by a rodjl". The nippers are swung back and forth at the required periods-by means of a cam jls, .carried by the drive-shaft E, which cam engages a stud or roller jlf, carried by one arm of a rocking lever j20, the other arm of which is connected to one of the armsj by a connecting-rod j21. i
The mechanism for raising and lowering the nippers is as follows: A pair of cams K are mounted on the drive-shaft E, each of which cams engages a stud or roller Za, carried by one arm of rocking lever 7c', the other arm of which is connected by a rod k2 with the free end of an arm 7a2, keyed to the crossshaft js. The upward and downward movements of the nippers do not interfere with the movements of the cam which operates the nipper-jaw J nor with the cam which swings the nippers backward and forward.
The comb for drawing the tufts snugly into position to be woven into the fabric after they have been inserted therein is constructed and arranged with its operating mechanism, as follows: The comb proper is denoted by L, and it has a plurality of downwardly-extended teeth Z, which are adapted to enter the spaces between the warp-threads when the comb is lowered. This comb Lis secured to the free ends of a plurality'of arms Z', keyed to a cross-bar Z2, carried by the free ends of a pair of arms Z3, keyed to a cross-bar Z4, mounted in suitable bearings Z5, carried by the frame. The shaft Z4 is provided with a downwardly-extended arm Z, which is provided with a stud or roller Z7. The cross bar or shaft Z2 is provided with an arm Z8, havinga stud Z9 at its free end. A verticallyreciprocating bar M extends through upper and lower brackets, the lower bracket projecting from the main frame and the upper bracket secured to the web-supporting plate B. The slot in the upper bracket is elongated, so as to permit the upper portion of the bar to be swung rearwardly a limited distance when so desired. The upper end of this vertically-reciprocating bar M is developed into a hook m, which is held in engagement with theI stud Z9 by means of a spring m, leading to the supporting-bracket for the cloth-winding roll B2. An operatingbar Nis arranged to operate the rocking arm Z6 and the vertically-reciprocating bar M for imparting to the comb L an upward, forward, downward, and rearward movement, as follows: The rear end of the operating-bar is hinged to the free end of a rocking lever n, having a stud or roller n', held in engagement with a cam @z2 on the shaft E by a spring n3. The bar N is provided near its forward end with a pair of adjustable collars n4 @@5, which are provided with projections adapted to alternately engage the stud Z7 on the free end of the arm Z6. These collars are so arranged that as the bar N is slid rearwardly or forwardly there is a shortlost motion before they are caused to engage the stud Z7 and rock the arm Z6. The bar N is further provided with an adjustable collar n, which is provided with an incline 77,7, arranged to alternately raise and lower the bar M, and thereby the comb L.
By reason of the hook @n being held yieldinglyin engagement with the stud Z9 the said hook maybe swung rearwardly, thereby disengaging the said stud and permitting the comb to be swung out of the way of the cloth when so desired.
The collars n4, ni, and a@ are so arranged that when the cam @1,2 is rotated to cause the IOO IIO
bar N to slide forwardly the comb is first raised and then moved forwardly, and as the movement Yof the bar is reversed the comb will be first lowered and then drawn rearwardly intoits original position.
The means which we employ for advancing the chains G a sucient distance to bring the spool-holding frames in position to be successively engaged by the transferring mechanism is as follows: Aratchet-wheel O is keyed to the rotary shaft g', upon which the sprocketwheels g are mounted. Adjacent to the ratchet-wheel O a disk o is loosely mounted, which disk is provided with aspiring-actuated pawl o', arranged in position to engage the teeth of the ratchet-wheel O, so as to rotate the said ratchet-wheel when the disk is rotated in one direction, but to idly slip over the said teeth when the disk is rotated in the opposite direction. A spring o2, leading from the main frame to the disk o, tends to return the disk to its normal position after it has been partially rotated for advancing the ratchetwheel O, and thereby the chains G, the required distance. The disk o is partially rotated in a direction to advance the chains G by means of a rocking lever P, having a sector portion p, from which a chain p leads to the periphery of the disk o. This rocking lever Pis suitably mounted on the frame A and is provided with a second arm p2, from which a rodv p3 leads to a rocking lever p4. This rocking lever p4 is provided with a stud or roller p5, which is engaged by a cam p7, mounted on the drive-shaft E.
When it is desired to work the design in reversed order, we have provided the following means for reversing the movement of the chains-as, for instance, when the threads upon the last spool of the series have been used: A disk Q is loosely mounted upon the shaft g upon the opposite side of the ratchetwheel O from the disk o. This disk Q is connected with the arm p of the lever P by means of a chain q, and a spring q leads from the main frame A to the disk Q, tending to return the disk to its normal position after it has,
been operated by the lever P. The disk Q is provided with a spring-actuated pawl q2,which is adapted to be engaged with and disengaged from the teeth of the ratchet-wheel O. The spring o3 of the pawl 0' and the spring Q3 of the pawl q2 are so arranged that they lwill hold the pawls either in or out of engagement with the ratchet-wheel O. When the pawl o is held in engagement with the ratchetwheel O, the chain is moved in one direction as the lever P is operated andwhen the pawl q2 is held in engagement with the "ratchetwheel O the chain is moved in the opposite direction. The pawls 0 and q2 are preferably provided with thumb-pieces projecting out beyond the peripheries of the disks o and Q, so that the said pawls may be readily operated by hand.
The means employed for bringing up the weft-threads into close proximity to the tufts when the weft-threads have been led across the shed by the shuttle, so that the reed upon the lay-beam may engage the thread at all points and beat it up, is as follows: A rocki rocking lever r4, the other arm of which is provided with a stud or roller T5. This stud or roller r5 is held in engagement with a cam r6,mounted on the operating-shaft E,by means of a retracting-spring T7. These arms r r do not interfere with the lay-beam F, and their forward and backward movements are so timed relative to the movements of the laybeam that the said arms are caused to positively bring the weft-thread into position to be engaged by the reed or comb attached to the lay-beam as the lay-beam swin gs forwardly.
In our improved loom the nippers insert the tufts around the weft-thread and are operated from below the warps, the said nippers being projected upwardly between the Warpthreads to grasp the ends of the yarns upon the spools, which are brought down to a convenient position just above the fell of the cloth from the chains by the transferring mechanism. The ends of these tuft-threads project but very little below the guides gm, and they are held accurately in position, so that the nippers are caused to grasp all of the ends evenly and firmly. When the nippers have closed upon the ends of the tuftthreads, an upward movement of the spools draws od the required length for the tufts, which are then severed by the cutting mechanism. The nippers are then caused to move downwardly until one-half of the length of the severed tufts is held below thewarps close to the fell, with the other half extending above. A shot of weft is then thrown in and beaten up. The nippers are then caused to move upwardly, thereby carrying the ends, which they hold up around the said weftthread. The nippers are then caused to release the tuft-threads as soon as they are carried to the proper height. After releasing the tuft-threads the nippers continue their upward movement until the ends are straightened. above the fabric and near the fell, with its teeth projecting downwardly, is caused tomove forwardly over the tops of the nippers' IIO The comb L, which is mounted just o 4.spreading and mixing with each other.
pers so constructed and operated insure the greatest accuracy in these movements, so that the surface of the fabric is almost perfect as it comes from the loom, thereby reducing the loss by shearing and finishing to a minimum.
The comb as constructed and operated serves other useful purposes besides keeping the ends of the tufts in position. It serves in lieu of templets to keep the fabric out to its full width, and it also keeps the groups of warp-threads separated, so as to give a passage for the nippers as they rise through the Warp to take the ends of the yarns. The comb may also be raised by hand and swung out of the Way for convenience in inspecting y the Work or mending the threads.
By constructing, mounting, and operating the spool-carrying frames in the manner hereinbefore described the loom is rendered capable of weaving carpets of any desired Width in a simple and effective manner.
It has been found very difficult to weave tufted fabrics of this character over a yard in Width for a great many reasons. Some of these reasons are that it is necessary that the bars of the spool-fram es to which the tu ftguides are attached shall be kept perfectly Y straight and that they shall not be liable to spring out of line, but shall present the ends of the tuft-threads projecting from the guides in an even and uniform row. At the same time these bars must be light enough to be handled by the operatives, (chiefly Women and young girls,) who have to remove the spools from the frames when the spools are empty and put in full spools and insert the ends 0f\ the tuft-threads into the guides ready to be attached to the carrying chains. In our structure of loom Very Wide fabric may be woven with very little increase in weight or bulk per foot of increase in Width in the loom.
By providing a greater or less number of pairs of chains We may employ and present in proper position any desired number of spools in an alined row7 and we may keep the frames of light Weight, We using only one bottom bar, the employment of the old form of one-bar frame enabling the weight of the frame to be kept at the minimum. These frames when brought to their proper position hold the very light.
The use of pairs of chains for each section of the spool-holding frames and the use of a single device for detaching from -the chains all of the `sections in one ro1 at once renders it feasible to form very wide fabric. Heretofore in looms employing one pairof. chains to carry a series of frames each having a single spool provided with a series of tutt-yarns the parallel chains of the pair have been placed at a distance apart greater than the length of the spool. The arms extended from .the spool-frames and engaging the links of always terminated on the frame Within a line,
cutting the spool and frame at right angles to their length just inside of the head of the spool. Feeling that light-weight spool-frames could be carried with great accuracy by pairs of chains and being desirous, therefore, of utilizing such method of moving a series of spool-frames alined in a row, we have after 'considerable study been able to utilize a plurality of pairs of chains to present a row of alined spool-frames and spools in such manner that a long row of ltufts might be inserted at one operation and, said tufts be properly and uniformly spaced. To do this, We ascertained by experiment that the old pairs of chains should be brought closer together, so that the two chains of each pair should be separated one from the other fora distance less than the length of the spool carried by the frame, and that the arms Q7, carried by and extended from the frame to engage the chains, must be extended from the sides of the frames rather than from their ends, and that the plates g11X or equivalent thread-guiding means having eyes for the tutt-yarns should be practically continuous at one side of the plurality of alined frames throughout the entire length o f the rowr of yframes used, and consequently we have arranged these guides or eyes substantially to the ends of the frames, so that the eyes receiving the guides are enabled to space equally apart all the tuftyarns to be used in the formation of a long row of tufts.
The method of constructing, supporting, and operating the shears by which the tufts are cnt from the body of the yarns on the spools is especially valuable in connection with looms for weaving wide fabrics by reason of its obviating the necessity of great proportional increase in the Weight and bulk of the operating parts in order to give them sufficient rigidity. ln looms heretofore used the arms or bars to which the shear-blades are attached are supported only at their ends. In our structure it will be seen that the blades are supported at as many points in their lengths as may be necessary to keep the blades firmly in contact at the points of cutting, all though the blades themselves may be made Furthermore, the raising and4 IOO IIO
lowering of the cutting mechanism substantially in unison with the raising and lowering of the spool-frame-transferring mechanism gives an unobstructed View of the warp and fabric when the cutting mechanism is raised, thereby giving the operative free access to the said warp.
There are various ways of combining the Warp and weft forming the body of the fabric. Some goods are made with two shots of weft for each row of tufts, some with three shots, and some have been made with four. Any of these goods may be woven on our loom by adapting the movement of the harness, the lay, and the weft-inserting devices to the movements of the other parts of the loom Without interfering in any way with the structure and arrangement of the novel portions ofthe said loom.
By the use of the reversing mechanism for the spool-frame-carrying chains we are enabled to reverse the movement of the chains at any time, and thereby produce a reverse pattern in the fabric when so desired.
The mechanism for engaging the weftthreads and bringing them up into close proX- imity to the tufts at all times insures proper beating` up of the said weft-threads by the forward movements of the lay-beam.
It will be seen that the shuttle-race is stafionary, and the lay-beam reed being necessarily in front of the race it is necessary that it should be swung down below the warp when the lay-beam is at the limit of its backward movement a sufficient distance to permit the weft to be carried toward the fell, so
as to be in front of the reed when itis moved forward. By the arrangement which we have shownland described the arms r r' maycarry the weft forward the instant the sh uttle clears the Warp, even before the shed begins to close. The arms being very light may have a rapid movement and a longer range of motion than the heavy lay-beam and may be swung backward and downward sufficiently far to allow the weft to pass over their ends, while at the limit of their forward movement they will rise considerably higher above the warp than the lay-beam reed. Another great advantage in this construction is the fact that the lay-beam may be swung only a very short distance, which is very desirable in view of the fact that the said beam is necessarily quite heavy where wide fabrics are being woven.
The curved guides g3, `over which the chains G are led, serve a very important function in that they permit a very long chain to be utilized by permitting the chain to be bent back upon itself for a considerable distance, the use of sprockets for this purpose not'being possible because of the spool-holdin g frames being in the way.
A loom constructed ,in the manner above described is not only capable of weaving very wide fabrics, but is also capable of weaving the samein an accurate and expeditious manner. By forming the pile of fabric upon its upper surface instead of its under surface the operative is enabled to see any imperfection in the weaving or in the pattern thereof immediately after it is woven instead of at a considerable time thereafter.
It is evident that changes might be resorted to in the form and arrangement of the several parts without departing from the spirit and scope of our invention. Hence we do not wish to limit ourselves strictly to the structure herein set forth; but,
