- the power for winding the fabric is mainly supplied through the sprocket-wheel and friction-plates, while the slower motion of the feed-rollers causes the sprocket-wheel driven positively thereby through the chain to slip l between the friction-plates, and thus compensate any difference of movement between the cloth-beam and feed-rollers.

- the shed is now opened by traversing one set of reels across the warp-line, the others remaining disengaged and in their normal position.
- the weft-carrier then travels to the other side of the fabric, laying the weft-wire in the shed at the Weaving-line, the weft and warp wires being acted upon by the comb, the reed, the temple, and the feed in the manner hereinbefore described.
- the weaving-arm or weft-carrier then retraces its steps to its former position, these movements being alternately and successively repeated until the weaving is completed.

SPECIFICATION forming part of Letters Patent No. 427,105, dated May 6, 1890.
Application led April 9, 1889. Serial No. 306,617. (No model.)
To all whom t may concern:
Be it known that I, HENRY B. MORRIS, a citizen of the United States, residing at Geneva, in the county of Ontario and State of New York, have invented certain new yand useful Improvements in Looms for Veaving Vire-Oloth, of which the following is a specification.
This invention relates chiefly to looms of that class in which the warp-threads are mounted on carriers capable of being separated in opening the shed, so as to permit the traverse of a weft-guide whose path intersects that of the carriers, in contradistinction to the ordinary way of opening the shed by separating the warps between the warp-beam and the reed and passing a shuttle therethrough.
One principal object of my invention is to enable one set of warp-threads to be traversed across the line of the warp independently of the others. This end I attain by mounting each warp-thread in a separate and independent carrier and combining it with mechanism which at the proper time seizes it, traverses it athwart the normal line of the warp, restores it to its normal position, releases it, and retracts, leaving a clear passage for the traverse of the weaving-arm, weft-guide, or weft-carrier.
My invention consists in combining with separate and independent warp-reels traversing athwart the normal line of the warps corresponding guides divided in that line, from one set of which guides to the other the warpreels are transferred in their traverse.
My invention further consists in combining with a separate and independent set of warp-reels such as above mentioned a corresponding set of warp-reels arranged in a diiferent plane and so organized that the entire series traverses simultaneously athwart the line of warp, so as to simplify the organization. without impairing the efficiency of its operation.
My invention further consists in combining with warp-reels such as described a tubular weft-carrier through which the weft-'thread passes, which weft-carrier traverses periodically from selvage to selvage of the fabric to lay the weft-wire in the shed.
My invention further consists in combining with the warp-reels and weft-carriers a comb or combs regulating the warp-threads and conforming to their movements, so as always to maintain control thereof.
My invention further consists in combining with the weft-carrier a reed whose path intersects that of the weft-carrier to lay the weft-thread in position.
My invention further consists in combining v bodying all my improvements, in the best wayl now known to me, as is necessary to illustrate the subject-matter herein claimed. Some of these improvements, however, may be used without the others, and in machines differing in its details of construction from those herein shown.
As my invention contemplates the application of these improvements to the most highly organized looms of the present day, I do not confine myself to the details of construction and organization herein shown; but when specifying a particular construction or organization intend to include well-known equivalents therefor. That end of the loom carrying the cloth-beam I term the front end, the opposite one the rear end or back That side of the machine on the right of the person standing at the back end of the loom and facing it I term the right-hand side, the opposite one the left-hand side.
Figure l represents a' view in elevation of the right-hand side of the loom with some of its framing or standards removed the better to show its working parts. Fig. 2 is a plan or top view thereof with portions of the guidesupports removed to show the parts beneath more clearly. Fig. 3 shows an enlarged detail side view of one of the independent warp-reels and its carrier; Fig. 4, asimilar view ofone of the set of connected warpreels and their carrier. Fig. 5 is a similar diagrammatic detail perspective View showing several of the independent warp-carriers, their guides, and the relation of the unwoven warp-Wires thereto. Fig. 6 is an enlarged detail elevation of the mechanism by which the shaft which drives the weft-carrier is actuated. Fig. 7 is an enlarged diagrammaticperspective view showing one of the temple-pins for guiding the weft-wire, with its actuating a'nd disengaging mechanism.
The mechanism is carried on a strong frame or bed-plate A, as usual. A main drivingshaft B, journaled in this frame, is driven in ordinary ways from any suitable primel mover. Cams, hereinafter described, actuating the various working parts are mounted on this shaft. In this connection each warpwire is shown as carried by a separate reel. The reels of the alternate wires are arranged in separate sets in different transverse vertical planes, so as to traverse in parallel vertical longitudinal planes without interference with each other, which organization econo-A mizes space and affords other advantages hereinafter enumerated. The reels, necessarily being wider than the space ordinarily desired between the warp-threads, if all arranged in the same plane would necessarily occupy a much greater space laterally than that required under this organization, and would require corresponding modifications of the loom to meet this contingency.
The rear reels C, Fig. 4, each consists of a central hub with two disks attached to the sides thereof. Each reel turns freely independently of the other upon a transverse shaft C', mounted in bearing-blocks c near each end, each of which has a curved recess' into which the guides C2 C3 enter. rFhese guides preferably are made in the form of pins polygonal in cross-section, curved in an arc of which the point where the weftwire is laid in the shed, which I term the weaving-line, is the center, the recesses being correspondingly shaped in outline and curvature. These guides are shown as arranged in two transverse rows or sets on opposite sides of the normal or medial line of traverse of the warps, which I shall hereinafter term the warp-line, one set of guides being secured upon a base F and the other set upon a transverse bar F3, mounted on suitable standards on the frame.
The bearing-blocks c are united near their lower ends and on opposite sides thereof by transverse bars C4 C5, and near theiropposite forward ends by a corresponding bar C6, provided with a series of longitudinal openings corresponding with the distance between the reels, from the inner side of which or that next the warp-line each warp-thread passes through itsrespective slot,proper tension being given each wire in its passage therethrough by means of a pin C?, (shown in dotted lines, Fig. 4,) movable endwise and transversely thereto in a hole in the bar C6 and pressed against the wire by a coil-spring C8, the tension of which is adjusted by set-screw G9 in a well-known Way.
Each bearing-block is provided with a catch c2, with which a lifting-hook, hereinafter described, engages at the proper time to traverse the reels athwartthe warp-line. As a consequence of this organization, all the reels of this set are simultaneouslytraversed, which matter will be hereinafter further explained. The other or front set of reels is differently constructed and organized. They each consist of a metallic frame or carrier D, whose front and rear edges are grooved and curved to iit their respective guides in an arc of which the weaving-line forms the center. A transverse central opening in each frame receives a reel consisting of a central hub e, to the ends of which two flat disks E of sheet `metal are attached, their diameter somewhat exceeding that of the above-mentioned transverse opening, which disks fit countersunk recesses e in the frame, so as to hold the reel securely in position, while allowing it to turn freely, with its disks flush with the surface of the frame.
Each reel is provided with a central opening for the insertion of a shaft to facilitate the winding of the warp thereon; but each reel, unlike the other set, enters separately and independently of the others, and will hereinafter be more fully explained. The wire passes from the reel through a narrow vertical slot e4 in the front part of the frame, proper tension being maintained thereon by a spring-pressed pin e2 and adjusting-screw e3, similar to those hereinbefore described, the wire being supported against this pressure by the wall of the slot above mentioned. A rearwardly-projecting catch d likewise engages with its appropriate lifting-hook at the proper time, as hereinafter explained. The movements of these reels are regulated by guide-pins f f2 f3 f4, mounted on suitable supports on the frame, the lower support being the same as that of the rear reel-guide hereinbefore mentioned, while the others are supported on transverse bars, one of which F4 is mounted in suitable standards on the frame, while the other F3, similarly mounted, is the same as the support o f the corresponding guides of the rear reel. These guide-pins, it will be observed, are arranged in four sets, two front and two rear ones, on opposite sides of the warp-line, all curved in the arc of which the weaving-line forms the center, the object of which is to maintain the reels at a uniform distance vfrom said weaving- IOC IIO
line, and consequently maintain a uniform tension on the warp-threads. The upper and lower front pins, it will be observed, are slotted longitudinally for some distance at their ends next the warp-line, so thatthe warp wires from the front reels may pass therethrough and be properly guided. The rear warp-wires, it will be observed, pass toward the weaving-line between the guide-pins of the front set, which thus serve as lateral guides therefor. These pins, it will'be observed, are of such relative lengths that the opening between the forward pins f2 f4 is considerably higher than that between the rear pins j" f2, the object of this organization being that the rear warp-wires shall always be under the guidance of the forward pins, as by it the Wires in their transverse movements pass between one set of pins before escaping from the other. The organization is such, it should be noted, that the front and rear sets of reels traverse alternately in opposite directions athwart the warp-line, so that when the rear wires are crossing the space between the adjacent ends of the guide-'pins the forward reels are doing the same in the opposite direction. ConsequentljT they close this space and prevent the rear wires from escaping laterally therethrough. In order still further to prevent possible entanglement of the rear wires with the forward reel-frames, the latter are made slightly thinner than the diameter of their forward guide-pins, thus leaving room for the wires to pass between the pinswithoutinterference from the reel-frames.
- These-forward reels, as-'before remarked, are
not mounted upon a common shaft, as are the rear ones, but each turns in a separate and independent frame, so as to permit the wires to pass between as they traverse athwart the warp-line, this traverse being effected by lifting-hooks engaging their catches in the following manner:v Transverse rock-shafts G H are respectively mounted on the main frame just below the weaving-line, and are connected by sector-gears g, causing them to rock alternately in opposite directions, this movement being caused by a cam b on the main shaft B engaging a friction-roller b on one end of a rocking arm G', fixed on the rock-shaft G. Each of the rock-shafts G H extends beyond the frame and carries rocking arms G2 H at each end thereof, one set being on the inside and the other on the outside of the bed-plate or sidel pieces of the frame, so as to prevent interference. Each of the rocking arms G2 is connected to its fellow H by I a chain or rope g2, preferably of metal, passing from the arm G2 over a pulley G3, thence backward to its fellow arm H. This pulley is suspended from a bar F4, mounted on the bars F' F2. The rope above mentioned encircles a lug 7L on a block h2, longitudinally adjustable on a guide h3 on the rocking arm H', locked in any desired position by a setscrew h5, the end of the rope being attached to an eyebolt h4, passing through a lug h6 on j across the machine.
` hereinbefore described.
the rocking arm, provided with a'suitable adjusting-nut to tighten the rope,thus affording means for 'correcting the radial distance of the rope from the center of motion, so that it may at all times be kept tight and preserve the proper counterbalance and relation of the rocking arms G2 H'. Owing to this method of connecting the rocking arms their respective sets ofI reels will be counterbalanced, which is important, as their weight is constantly varying, the reels being gradually lightened as the wire is unwound therefrom. The free ends of the rocking arms above mentioned are respectively connected by connectingrods I J to the rock-shafts z' j, extending Hooks ol' upon theopposite ends of the rear rock-shaftt' engage at proper times the corresponding catches o2 upon the lifting-blocks c' of the rear reels, The rocking motion necessary to effect the engagement and disengagement of these traversing blocks and hooks is effected in the following manner: Radius-bars I' oscillate on a shaft z2 in standards on the main frame. A crank-arm 3 on the rock-shaft 1,' is connect-ed by aparallel rod 12 to bell-crank lever I3, rockingv on the 'same shaft as the radius-bars' above mentioned. The other end of the bell-crank is connected by a link-rod K with rocking lever K', carryin g a friction-roller vtraversinga grooved cam K3 on the driving-shaft. The organization is such that when the lifting-hooks are nearest their lifting-blocks when in their normal position they are locked into engagement therewith by means of the link-connections above described in a manner that will be readily understood.
The organization of the apparatus for controlling the front set of reels is similar to that above described, and the parts are correspondingly lettered. In this case an independent hook L, mounted upon a transverse rock-shaft j, is provided for each reel, the shaft and hooks being operated through radius-bars J', bell-crank J 3, connecting-rods K2. rocking lever K4, cam K5, crank-arms js, and parallel rods J2, similar to those in the front set.
The weft-thread is, laid between the warpthreads by what Iv call a weavingarm, weft-guide, or weft-carrier, alternately traversing from side to side of the fabric. This weft-carrier consists of a hollow tube N. preferably flattened and widened at its forward end to enable it to work close to the weaving-line and to render it less liable to catch in the warp-wires, across which it moves laterally, through the entire length of which tube the weft-wire passes and is deposited between the wires at each shed. The rear end of the weft-carrier is mounted upon a block N', sliding in a transverse guide consisting in this case of two parallel guide-bars n n', extending across the rear end of the machine and secured in' standards N2 thereon. The weft-carrier block is preferably oscil- IOO lIO
' tween the wires.
lated by means of chains or ropes o o', preferably of metal, being attached, respectively, at one end to the sliding block, extending in opposite directions from the sliding block andV encircling pulleys O O', mounted, respectively, in the standards above mentioned. Both of these ropes are wound in opposite directions upon a pulley P, mounted on a central longitudinal shaft P', turning' in proper bearings in the frame. A gear-wheel P2 on this shaft is actuated by a rack P3 on a bellcrank lever P4, rocking on a central pivot in the frame. The opposite end of this bellcrank carries a friction-roller p, engaging with a grooved cam p on the driving-shaft, by which means it will be seen that the weaving-arm is caused at proper intervals to traverse the shed from selvage to selvage in one direction, deposit the weft-thread therein, to pause until another shed is opened, and then return in the opposite direction, this operation being alternately repeated from time to time as the weaving progresses.
The warp-threads are guided at a point between the reels and the weaving-line by combs, in this instance constructed as follows: Transverse bars R5 are provided with short upright teeth fr5 r6, preferably formed of small wires separated a distance apart equal to that the warp-wires are desired to be in the woven fabric, the warp-threads being designed to be laid between the teeth of the comb and retained laterally in position thereby. Two combs are shown, an upper and a lower one, both movable, respectivelymounted on parallel radius-bars R R', vibrating around shafts o r', connected by sector-gears r2 r3 to insure their coincident movement, the i,
lower radius-bar being provided with an extension-arm R4, operated by a friction-roller r?, engaging a cam r4 on the main shaft. The teeth rf of the lower comb are set slightly nearer the front of the machine or the weavingline than those r6 of the upper comb, the two being caused to oscillate correspondingly with the warp-wires in shedding and opening correspondingly as the shedding is completed,
. so that each comb moves coincidently with the warps with which it is engaged and separates them one fromthe other, therebykeepingthem always correctly arranged laterally, so that the blades of the reed will pass properly be- This reed consists of a series of oscillating blades S, rigidly secured upon a transverse rock-shaft s, mounted in the main standard and vibrated at suitable intervals by sector-gears s thereon meshing with corresponding gears s2 on the end of a lever S', rocking intermediately on a pivot 33 on the left-hand side of the frame and carrying a friction-roller actuated by a cam s4 on the driving-shaft.
To prevent the weft-wire from drawing the edges of the fabric together, I use a temple at each side of the fabric, consisting of a vertical pin m on each side of the fabric at the weaving-line, mounted on an arm X, os-
cillating vertically, and curved laterally, so as to be clear of the fabric, while allowing the pin to en ter between the outer warp-wires and the adjacent ones on each side. This arm X is pivoted to a vertical oscillating lever X ,in turn pivoted on the main standard and acted upon by a spring X2; so as to hold the temple normally in position in engagement with the fabric, as hereinbefore described. The weftwire is carried around the temple-pins when in their forward position, and the continuous feed motion, hereinafter described, tends to draw them forward and downward, thus causing `the lever X to swing forward against the pressure of its spring. As the reed advances to lay the newly-deposited weft-wire a wiper or cam X8 on the reed-shaft strikes a pin win the side of the arm X, thus withdrawing the temple-pins from the fabric. As soon as this is done the spring throws the temple backward over the newly-deposited weft-wire and into position to receive the next one. The temple-pins and arms fall into their places by gravity after the retreat of the cams, but may be so actuated by springs, if desired; but this is not deemed necessary.
The temple mechanism above described is `alike on both sides of the loom, except that the temple-levers are of course right and left,
or reversed in their curvature.
Two transverse horizontal feed-rollers T T are mounted one over the other near the forward end of the bed-plate, the upper one T turning in bearings in sliding blocks t, pressed together toward the upper roller by springs t', to keep the rollers-closely in contact. The feed-rollers are continuously driven in opposite directions proper for feeding by spurgearing of well-known construction, (clearly shown in the drawings.) A spur-gear z on the main driving-shaft actuates a corresponding wheel Z on a counter-shaft carrying a spur-gear z', which drives a spur-wheel Z on the shaft of the lower feed-roller. A sprocketwheel t2 on the lower feed-roller drives through the medium of a chain or perforated belt T? a corresponding sprocket-wheel T3, loosely mounted upon a short transverse horizontal shaft t3, journaled in the upper forward portion of the right-hand side of the frame. A circular friction-plate U is fixed upon and turned with this shaft. A similar frictionplate U likewise turns with the shaft, but is connected therewith by a key or spline, so as to be free to move endwise upon the shaft while turning therewith. The sprocket-wheel T3 has smooth sides compressed between the friction-plates by a spring u, bearing against the outer side of the plate U', being compressed against it by an adjusting-screw U2 on the end of the shaft t3, so as to regulate the pressure thereon. A disk V is rigidly fixed upon the shaft t3 near its inner left-hand end. The proj ectingl end of this shaft forms one bearing for the cloth-beam or take-up roller W, the opposite end being mounted in a suitable shaft in the other side of the frame.

ITO
An eccentric-pin V projecting laterally from the inner face of the disk V, enters a corresponding recess in the end of the take-up roller or cloth-beam W, upon which the woven fabric is wound, the end of said fabric being positively secured thereto at the commencement of the operation. The left-hand shaft XV of the take-up roller is mounted in a screw-bearing tu and provided with a crankarm, so as to admit of the ready removal or displacement of the cloth-beam in a wellknown way. The organization is such that the surface of the cloth-beam tends to travel somewhat fasterthan the surfaces of the feedrollers; but this tendency is counteracted by the slipping of the friction-plates through which the cloth-beam is driven. The feedrollers thus tend to detain the fabric and reduce its motion to the proper speed, which would otherwise be irregular, increasing as more cloth is wound upon the beam. The power for winding the fabric is mainly supplied through the sprocket-wheel and friction-plates, while the slower motion of the feed-rollers causes the sprocket-wheel driven positively thereby through the chain to slip l between the friction-plates, and thus compensate any difference of movement between the cloth-beam and feed-rollers.
The following is adescription of the operation of the loom: Each reel is threaded with a center warp-wire, which is led through its proper guides and through the loom and secured to the cloth-beam, as usual. Normally all the reels rest in their lowest position below the warp-line. The weft-thread is passed through the carrier from a suitable reel and its forward end properly secured in the loom. The weft-carrier, it will be observed, is bent to correspond with the openings between the guides and its flattened and widened point projects between and beyond the teeth of the combs and of the blades of the reed close to the temple and the weaving-line. The operation starts with the weft-carrier at one side of and outside of the line of the warps, as shown in Fig. 1, in which position it is outside of the supporting-shaft of the rear reels and of course outside of the supports of the front ones. The shed is now opened by traversing one set of reels across the warp-line, the others remaining disengaged and in their normal position. The weft-carrier then travels to the other side of the fabric, laying the weft-wire in the shed at the Weaving-line, the weft and warp wires being acted upon by the comb, the reed, the temple, and the feed in the manner hereinbefore described. After completing its travel across the warp in one direction the weft-carrier pauses at the opposite end of its stroke, while the set of warpreels previously traversed across the warpline is traversed back to its original position, the other one being simultaneously seized and carried to the opposite side, as before. The warp-reels restored to their normal position being disengaged from their lifting-hooks,
the weaving-arm or weft-carrier then retraces its steps to its former position, these movements being alternately and successively repeated until the weaving is completed.
The operation of the feed and other devices will be readily understood from the foregoing description, and need not be described herein.
