JOHN LLOYD MOKAT, OF KINGS MOUNTAIN, NORTH CAROLINA.

SPECIFICATION forming part of Letters Patent No. 567,851, dated September 8, 1896. Application filed June 26, 1895. Serial No. 554,111. (No model.)

To all whom it may concern.-

Be it known that I, JOHN LLOYD MOKAY, a citizen of the United States, residing at Kings Mountain, in the county of Cleveland and State of North Carolina, have invented a new and useful Loom, of which the follog:

ing is a specification.

This invention relates to looms; and it has for its object to effect certain improvements in that class of looms known as needlelooms, whereby simple and efficient means shall be provided for weaving the cloth in such a manner as to save both time and labor.

To this end the main and primary object of the present invention is to provide certain new and useful improvements for carrying out a mode of weaving that insures not only a quick weaving of theoloth, but also involves less attention to theloom than is ordinarily required.

With these and other objects in view, which will readily appear as the nature of the ina detail sectional view on the line 7 7 of Fig.

vention is better understood, the same consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.

In the drawings, Figure 1 is a front elevation, partly in section,'of a loom equipped with the herein described improvements. Fig. 2 is a vertical sectional .view on the line 2 2 of Fig. 1. Fig; 3 is top plan view of the construction illustrated. in 'Fig. 1. Fig. 4 is a detail in perspective'of the needle-shuttle. Fig. 5 is a central longitudinal sectional view of the needle-shuttle. Fig. 6 is a detail in perspective of the selvage-shuttle. Fig. 7 is 1. Fig. 8 is a detail in perspective of the rear movable shuttle-box for the selv'age-shuttle. Fig. 9 is a central longitudinal sectional view of the construction shown in Fig. 8. Fig.

10 is a diagrammatic view illustrating the ,manner in which the loop of the weft-thread is caught by the side loop-holding thread.

Fig. 11 is a detail sectional View on the line 11 ll of Fig. 3, looking toward the threadpan side ofthe machine and omitting certain parts, so'as to clearly illustrate the connection between the main and false battens. Fig. 12 is a similar view, also on the line 11 11 of Fig. 3, looking in an opposite direction to the view illustrated in Fig. 11. Fig. 13 is a detail in perspective, showing clearly the threads of the loop of the weft when it is carried through the shed of the warp and also the corresponding angle'formed between the main and false battens when the same have reached the limit of their backward beats or strokes. Fig. 16 is a diagrammatic sectional view illustrating the engagement of the-slayplate of the false batten with the lower thread of the weft-loop, so as to force such thread up into place in the warp in advance of the other thread of the loop which is carried up by the slay of the main batten. I r

Referring to the accompanying drawings, 1 designates a part of the main frame of a loom, within which is arranged to work the usual swinging batten 2, that is moved back and forth by means of the pitmen 3, connected with the batten and also with the cranks 4 of thefcrank-shaft 5, journaled within the frame 1 and carrying upon its opposite extremities the belt-wheels 6, one of which beltwheels receives the belt 7, that is driven from the belt-wheel 8 from one end of a driveshaft 9, journaled in the frame below the shaft 5, and carrying upon the end opposite the wheel 8 the belt wheel or pulley 10, that receives the belt for transmitting motion to the working parts of the machine. The gearing connections just described are simply those connections that are necessary to illustrate the working of the parts employed in connection with the herein-described improvements. 1 v

The batten 2 carries the usual reed 11, and is provided at its opposite ends with the end shuttle-boxes 12, that are adapted to receive therein the needle-shuttle 13, which carries the weft-thread through the shed formed by the crossed warp-threads, which are crossed and recrossed in the usual manner by means of the ordinary harness. (Not shown.) The end shuttle-boxes 12 of the batten are provided at their opposite inner sides with the reversely disposed bowed shuttle holdin g TOO springs 13 between which the needle-shuttle is forced and is firmly held in place before being started on its way toward either end of the batten, and the said needle-shuttle is -driven across the batten and through the shed by means of the ordinary picker-sticks 14, the upper ends of which work in the slots 15, formed in the ends of the batten, and which picker-sticks are oscillated by the ordinary picker mechanism.

In the present invention the needle-shuttle consists of a solid body pointed at both ends, as at 14, so that the same will readily enter the shed of the warp in being started on its travel toward either end of the batten, and on its upper side the said needle-shuttle is provided with a longitudinal thread-groove 15,leading from one end of the shuttle-body to an intermediate point, where it communicates with a thread-eye 16, that opens into an enlarged thread-recess 17, form ed in the lower side of the shuttle-body. The said threadrecess 17 communicates with the bottom thread-grooves 18, formed in the lower or bottom side of the shuttle-body and extending from the recess 17 to the extreme ends of the shuttle-body to receive therein the lower portion of the weft-thread 19 as the needle-shuttle is moved back and forth through the shed of the warp. It will be understood by reference to Fig. 5 of the drawings that on its forward movement the needle-shuttle 13 will carry the weft or woof thread in a loop through the shed of the warp, thereby weaving two weft or woof threads in each cross of the warp instead of one, as in the ordinary method of weaving. In this movement of the needle shuttle a portion of the weft-thread will lie in the thread-groove 15, and a portion will also lie in the bottom thread-groove 18,1eading toward the rear end of the shuttle-body, and on the reverse movement, when the needie-shuttle travels back on the upper strand of the weft, the lower strand of the weft will lie in the short thread-groove 18, leading from the recess 17 toward the'front end of the neodie-shuttle.

The needle-shuttle 13 is provided near one end and within the upper thread-groove 15 with a threading-eye 20, through which the thread 19 is threaded before being passed through the main eye 16 of the shuttle, and the eye 20 provides for holding the weftthread properly thread ed in the needle-shuttle, so that the said shuttle will carry the weft or woof thread evenly through the warp. The weft-thread 19 is evenly distributed or paid out to the needle-shuttle 13 by means of the revolving thread-pan 21. The thread-pan 21 is supported in a horizontal position and is provided with a centrally-perforated depending collar 22, mounted for rotation in the bearing-support 23, secured at one side of the frame 1 of the loom, and at its lower end the depending collar 22 of said thread-pan is provided with a pulley 24, over which is passed one portion of an operating-belt 25, that leads of a pair of feed-rollers 38.

in a horizontal direction from the pulley 24, and the separate portions of which belt pass over the idler-pulleys 26, suitably mounted within the frame of the machine at one side thereof. Below the idler-pulleys 26 the belt 25 passes over a drive-pulley 27, mounted-on the crank-shaft 5 near one end thereof, thus completing a drive connection for imparting rotation to the thread-pan 21.

The thread-pan 21 is provided with a peripheral upturned flange 28, inside of which flange is coiled sufficient of the weft or woof thread to supply the demand of the needleshuttle during each complete throw thereof. The thread-pan revolves just fast enough to coil within the flange thereof, without kinking, a sufficient number of convolutions of the weft-thread to supply the needle-shuttle, as already stated, and this coiling of the weft-thread within the weft-pan, to prevent tangling or kinking thereof, is positively insured by means of the conical pan-cover 29. The conical pan-cover 29 is arranged directly over the thread-pan 21 and is properly supported in position from its apex, as at 30, by means of a swinging bracket 31, pivotally connected, as at 32, to opposite sides of an upright bearing-frame 33, supported on one side of the main frame of the loom. The bracket 31, by means of its pivotal support, allows the cover 29 for the thread-pan to be readily lifted up out of the way when it is necessary to thread the weft through the collar of the thread-pan, or for any other purpose, and the said conical pan-cover 29 is provided at its lower edge with a vertically-disposed flange 34, that lies within the threadpan a sufiicient distance from the flange 28 thereof, so as to cause the weft-thread to coil within the thread-pan as the latter revolves, and at the same time the thread-pan cover acts in the capacity of a protector for the weft-thread within the thread-pan.

The weft-thread is guided into the space between the flanges 28 and 34 by means of the inclined tubular thread-guide 36, properly supported in position above and at one side of the thread-pan by means of the bracketarm 37, attached to the upright bearingframe The thread is fed into the upper end of the tubular thread-guide 36 by means The feed-rollers 38 are arranged one above the other within the bearing-frame 33, and the spindle extremities 39 of said rollers are journaled in the opposite vertically-distmsed bearing-slots 40, formed in opposite sides of the frame 33 and communicating at their upper ends with openings 41, that provide convenient means for readily removing or replacing the said feed-rollers. The lower of said feed-rollers 38 has mounted on one spindle extremity the belt-wheel 42, over which passes the upper portion of the belt 43, that is driven from the belt-wheel 6 at one end of the crank-shaft 5, and provides means for transmitting a positive motion to the lower feed-roll, so that the through the central combined bearing and thread-collar thereof. passes between the feed-rollers 38 is drawn The weft-thread that by said rollers from the spool 44, mounted within the upper end of the frame 33, and the spindle extremities 45 of which spool are removably fitted in the bearing-notches 46,

formed in opposite sides of the frame 33 at the upper extremity thereof, and at this point it will be noted that by reason of feeding the weft-thread to the main needle-shuttle from a spool a constant refilling of a shuttle is rendered unnecessary, as in the ordinary looms, because the spool 44 may carry 7 sufficient thread to run the loom constantly any desired number of hours without stopping.

The batten 2 has adjustably fitted to the front side thereof, near one end, a substan tially rectangular shuttle-box 47, the adjustment of said box being longitudinally of the batten, so that the box can be properly adjusted, according to thewidth of the cloth that is being woven. The adjustment of the box 47 may be conveniently secured by the employment of screws or bolts'47, passed through the flange 47? atone end ofthe box 47 and engaging in any of a series of openings 47, formed in the batten. The front shuttle-box 47, that is fitted to the, front side ofthe batten'near one end, is provided at opposite inner sides withoppositelydisposed shuttle-holding springs 48, between which is adapted to be forced and held in position within the front shuttle-box a selvage shuttle 49, that has a travel at direct right angles to the needle-shuttle and directly adjacent to the edge of thewarp opposite the threadfeeding mechanism for the needle-shuttle. The 'saidselvage-shuttle 49 consists, essentially, of an elliptically-shaped body provided with an enlarged spindleblock 50 at one end, and to which spindle block is fitted the thread-spindle5l, that carries the loop-holding thread 52, that is adaptedto bepassed through the loop of the weft or woof at one side edge of vthe warp. The said selvageshuttle 49 is further provided with the opposite reversely-disposed bowed spring-tension arms .52?, that ,are extended from opposite sides of they spindle-block 50 directly over the main body of the shuttle. The vsaid spring-tension arms ,52 are also c'onvergently V disposed and are provided beyond oneend of the spindle 51 with the abutting flat claspflanges 53,-between which passes .theloopholdingthread 52. as it leaves the threadspindle, and which flanges also serve tohold the said loop-holding thread perfectly taut while the needle-shuttle is returning to its initial starting-point, so that the loop of the weft may be properly held bysaid loop holding thread until the slay of the batten has forced or driven the two weft or Woof threads properly in place between'the warp-threads.

The selvage-shuttle 49 is adapted to be engaged at one end by the strike-pin 55 at one end of the bell-crank hammer 56. The strikepin 55 of the hammer 56 is adapted to work j ustably secured to the front side of the batten 2, adjacent to the box 47, and it will of course be understood that the said shuttlehaminer 56 will have an adjustment corresponding to the box 47, so that these parts will'always maintain a proper relative position. The hammer 56 is adjustedby adjusting the pivot-plate 57, which is conveniently attached to the batten by means of a screw or bolt 57 passed through a flange of the pivotplate and engaging in any of a series of perforations 57, formed in the batten. The pin 55 at one end of the hammer 56 is normally held out of the box 47 by means of the spring 58, secured to the front side of the batten and pressing against one side of said hammer. 7 At one side of its pivot the hammer 56 is provided with a curved contact end 59, that is disposed within one of the' end shuttleboxes 12 of the batten and is adapted to be en gaged by the needle-shuttle when such shuttle is thrown into the said shuttle-box, and in this movement of the needle shuttle the curved contact end of the hammer will be forced outward, thereby imparting a sharp inward movement to the strike-pin, 55, which will forcibly strike against one end of the selvage-shuttle 49 and will driveth'e said selvage -shuttle out of the box 47 transversely across the batten 2'and into the movable rear shuttle-box 60,. arranged in rear of and in direct alinement with the front shuttle-box 47. The said rear shuttle-box 60is arranged in rear of the batten 2, and is supported in a proper position to provide for the proper movement of the selvage-shuttle 49, and the said rear shuttle box 60 is" essentially rectangularin shape and is open at its front "end to receive and eject the selvage-shuttle. The opposite sides of the rear shuttle-box 60 are provided withthe flared front ends 61, that 62, that press against the opposite sides of the selva'ge-jshuttle 49 to'provide for, properly holding the same Within the box 60. The movable shuttle-box 60 is supported to slide ,within'a stationary rectangular casing 63, that is 'adjustably supported within the frame 1,

adjacent to oneside thereof, bymeans of the' I,

sectional adjustable supporting-arms 64, suitably attached to the casing 3 and also toone side of the machine-frame, said supportingarms 64 having their separate members adjustably fastened together by means of the screws 64.

The movable shuttle-box 60 has fitted to the rear closed end thereof a slide-rod 65, that works through the guide-opening 66, formed in one end of'the casing 63, and a spring 67 is coiled on the rod 65 between the rear end of the box 60 and one end of the casing 63 to provide for normally moving the box 60 in a forward direction to provide for throwing the selvageshuttle from the rear shuttle-box across the batten and into the front shuttleat one end of the spring trip-wire 70. spring trip-wire 70 is secured fast at one end,

as at 71, to the under side of the stationary casing 63 and is provided with an inclined portion 7 2, against which works the trip-pin 73, projected from one side of one of the pitmen 3 and providing convenient means for automatically lifting up the free end of the wire 70 and disengaging the catch-hook 69 thereof from the catch-notch 01"; the rod 65, thereby releasing the box 60, so that the same will be thrown sharply forward under the influence of the spring 67. The forward movement of the box is arrested by the stop enlargement 74, formed on the rear end of the slide-rod 65.

Referring more particularly to the operation of the two shuttles, it will be assumed that the batten is at the point where it ends its forward movement to force up the weft or woof thread into the warp. When the batten is at this point, the needle-shuttle is within the shuttle-box adjacent to the feeding mechanism for the needle-shuttle, and the selvageshuttle 49 is located within the rear shuttlebox 60, in which shuttle-box the selvage-shuttle is always at rest when the batten is drawn to the front. Vith the two shuttles positioned as just stated the batten moves backward to the point to which the rear shuttle-box 60 would extend when released, and when the batten has reached this point the trip-pin 73 will cause the catch-hook 69 to be disengaged from the rod 65, so that the said rear shuttlebox 60 will shoot forward until it comes in contact with the rear side of the rearwardlymoving batten. This movement of the shuttle-box 6O throws the selvage-shuttle 49 across the batten and into the front shuttle-box 47. At the very moment the rear box 60 for the selvage-shuttle strikes the rearwardly-moving batten the needle-shuttle 13 is driven through the shed of the warp and carries a loop of the Weft or woof thread through the shed,thereby causing two weft or woof threads to be placed in the warp at one time. In this movement of the needle-shuttle the same comes in contact with the end 59 of the hammer 56 and causes the selvage-shuttle 49 to be immediately driven back into the rear shuttle-box 60, and in this movement it will be understood that the loop-holding thread 52 will be carried through the loop formed between the upper and lower strands of the weft or woof thread 19. It will be understood that the free end of the loop-holding thread 52 has been previously fastened in the box 47, or at some other convenient point at the front side of the batten, before the loom is started, and therefore when the selvageshuttle has been driven through the loop of the weft and into the rear shuttle-box 60 it will also be understood that the loop-holding thread 52 will be held taut and will therefore hold the loop of the weft while the needle-f through the loop of the weft-thread the needle-shuttle is immediately driven back to its initial starting-point through the same cross of the Warp, and therefore it will be seen that the needle-shuttle carries its thread into the warp from one side of the loom only, and after the needle-shuttle has returned to its starting-point the harness of the loom will have made another cross of the warp for'the needle-shuttle to repeat the operation already described.

The two throws of the needle-shuttle and the selvage-shuttles occur While the batten is moving rearwardly, and after the selvageshuttle has been thrown back into the box 60, after having been ejected therefrom, it will be obvious that the continued backward movement of the batten will force the box 60 back within the casing 63 until the catchhook 69 automatically springs into engagement with the notch 68, and thereby locks the rear shuttle-box 60 in its retracted position, ready for another throw forward immediately before the needle-shuttle is moved through the shed from its starting-point.

As the weft or filling thread is carried through the shed of the warp by the needleshuttle 13 the two threads of the loop of the weft are necessarily disposed at an angle to each other, inasmuch as the main batten is on its backward beat or stroke when the loop is carried through the shed of the warp The angle formed between the two threads of the weft-loop is very plainlyillustrated in Fig. 15 of the drawings, and in this connection it will be obvious that in order to make smooth and even cloth it is necessary to force the lower thread of the loop into place between the crossed warp-threads in advance of the upper thread of the loop, which is carried into place by the slay of the main batten. Otherwise both threads of theloop would be packed into place at the same time by the main batten and would produce rough and uneven cloth. To secure the desired result, a false IIO ' dle-sh uttle.

or supplemental horizontally-swinging bat- -1, and at one extremity the said false batten 76 isprovided with a squared spindle 78, whichhas a slidingfit in the slide-opening 79, formed in the upper end of a short pivotpost 80. The short pivot-post 80 is provided at its lower end with a reduced pivot-stud 81, that loosely fits in the socket 82, formed in the upper end of a supporting-block S3, suitably fastened on the same side of the frame as the thread-feeding mechanism for the nee- The construction just described provides a pivotal support for one end of the false batten 76, so as to leave the other end of the false batten free to swing back and forth in the space between the main batten and the breast-beam 77 during the operation of the loom.

The false batten 76 is provided adjacent to its pivotal support with a short spring-section 84, illustrated as consisting of a short spiral or coiled spring, and this spring-section 84 is designed to work under the beveled inner'end 85 of a shortstationary depressorarm 86, fastened at its outer end to the breastbeam 77, near one end thereof, and extending inwardly, so as to lie in the path of movement of the spring-section 8i of t-hebatten 76, in order to provide means for depressing the free or unpivoted end of the batten after the lower thread of the weft-loop has been forced up into place, as will be more particularly re ferred to. At its free or unpivoted end the false batten 7 6 is provided with the straight angled extension 87, which has fitted on the extremity thereof asegmental slide-button 88, having a lower rounded side 89. The segmental slide-button 88, which is fitted on-the free or unpivoted extremity of thefalse bat ten, is arranged to work in the grooves of the grooved guide-block 90, located at the side of the frame 1, opposite the pivotally-supported end of the false batten. The grooved guideblock may be either an integral or separate part of the frame 1, and is provided in its inner sidewith the upper and lower guidegrooves 91 and 92, respectively,'which communicate with eachother at both ends of the guide-block, and which are separated by means of adividing-strip 93. The dividing strip 93 is secured fast only at one end, as at 94, in the grooved sideof the'guide-block 90, thereby leaving the other end of the strip free to swing up and down under the adjusting influence of the slide-button 88 as the same travels in the grooves 91 and 92, and the said slide-button 88 is properly retained in position in the said grooves by means of a retaining strip or flange 05, secured to the inner face of the guide-block 90 and slightly overhanging the edges of the grooves therein.

The false batten 76 has fitted on theupper side thereof a slay-plate 96. The slay-plate 96 is adjustably connected at both ends, as at 97, with the batten 76, in order that the said plate can be properly adjusted to suit the position of the Warp-threads and thereby allow the teeth of the slay-plate 96 to work between said threads Without disarrangin g them. At its inner edge the slay-plate 96 is provided with a series of short upturned teeth 98, which are arranged sufficiently close to correspond with every other reed in the slay 11, carried by the main batten, and the teeth 98 are formed perfectly straight or square, so as to be adapted to pass up between the warpthreads sufficiently far to catch and carry the lower thread of the weft-loop with each forward movement of the false batten 76. forward movement of the false batten 76 is imparted thereto by means of the retractile spring 99, secured at one end to the front side of the batten 76 at an intermediate point,

and at its other end to the breast-beam 77 of the loom-frame. The backward movement of the false batten 76 is given thereto by the movement of the main batten 2, which has a detachable connection with said false batten, which connection will now be described.

The straight angled extension 87, at the free end of the batten 76, is provided with an upwardly-disposed catch-pin 100, that is adapted to be engaged by the shoulder 101 of the shouldered catch-lever 102. The lever 102 is pivoted at an intermediate point, as at 103, to the under side of the main batten 2,

near one end thereof, and the shouldered end 101 projects beyond the front edge of the batten 2, so as to readily engage with the catchpin of the false batten 7 6. the lever 102, opposite its shouldered or hooked extremity 101, has pivotally connected thereto, as at 104, one end of a trip-lever 105. The trip-lever is also arranged under one end of the main batten 2, and is provided at an intermediate point with an inclined slot 106, which slides over a stationary pin 107, secured in the batten 2. Opposite the pivotal connection 104 the lever 105 is provided with a rounded extremity 108,which projects across the lower side of the slot 15, at one end of the main batten 2, and directly in the path of the picker-stick 14, working in such slot, to provide means for disengaging the catch-lever 102 from the catch-pin 100 at the proper time.

Assuming both of the battens 2 and 76 to be drawn to the limit of their forward movement, the catch-lever 102, carried by the main batten, will be engaged with the catch-pin 100 of the false batten 76, so that the two battens will be locked together. As the main batten now starts on its backward stroke, the free or unpivoted end of the false batten will be carried backward with the main batten, thereby causing the two battens to assume an angle with respect to each other which corresponds to the angle formed between the two threads of the weft-loop which is carried through the shed of the warp. In this movement of the false batten the slide-button 88, at the free This 7 The end of I extremity thereof, travels in the lower guidegroove 92 of the block 90, which guide-groove serves to depress the false batten sufficiently far so that the slay-teeth 98 will entirely clear the warp and the weft thread therein, so as to obviate the possibility of the teeth 98 engaging with any thread except at the proper time. After the loop of the weft-thread has been carried through the shed of the warp by the needle-shuttle the slide-button 88 will have reached one end of the lower guidegroove 92, and in passing the unfastened end of the dividing-strip 93 the button 88 forces said unfastened end of the strip 93 upward, so as to allow the button to pass into the space beyond the unfastened end of the strip 93, which thereupon immediately assumes its normal position, so as to prevent the button 88 from returning in the lower groove 02, and causes the same to ride forward in the upper groove 91, which elevates the batten 7 6 sufficiently far so as to carry the teeth 98 in between the warp-threads and behind the lower thread of the loop which has been carried through the shed of the warp. However, the forward movement of the false batten 76 does not occur until the moment when the pickerstick, at one end of the main batten, strikes the needle-shuttle to drive the same back on the top or upper thread of the loop to its home-base or initial starting-point.

At the moment one of the picker-sticks moves in the direction to return the needleshuttle to its home base the said pickerstick moves against the rounded extremity 108 of the lever 105 and forces the said lever to one side of the slot 15, and therebymoves the lever 102 on its pivot 103, so as to disengage the shoulder 101 from the catch-pin 100 of the false batten. This operation immediately releases the false batten from the main batten, and the retractile spring 99 sharply draws the false batten to the front. In this forward movement of the false batten, just as the same is released from the main batten, the button 88 immediately rides into the upper guide-groove 91 and thereby elevates the false batten, so as to carry the teeth 98 up between the warp-threads and behind the lower thread of the weft-loop, and the continued forward movement of the false batten, under the influence of the spring 99, causes the lower thread of the weft-loop to be forced up into place between the warp-threads in advance of the upper thread of the loop, which is forced into place by the slay 11 of the main batten. WVhen the false batten reaches the position which is necessary to carry the lower thread of the weft-loop properly into place between the warp-threads, the spring-section 84 of the false batten becomes depressed by the beveled end 85 of the arm 86 and causes the button 88 to drop from the upper groove 91 to the lower groove 92 at the forward ends of such grooves, whereby the false batten will be lowered, so as to disengage the teeth 98 from the threads, and also so as to be brought to a position out of the way of the main batten, which forces the second or upper thread of the weft-loop into place between the crossed warp-threads. The false batten reaches its forward limit of movement in advance of the time when the needleshuttle reaches its home-base from the stroke of the picker-stick which released the false batten, and on account of this operation the needle-shuttle on its return movement has only to tighten and hold but the one upper thread of the loop until driven in place by the slayof the main batten. When the false batten has driven its thread in place and has been disengaged therefrom by the means described, the main batten will have reached its forwardlimit of movement in carrying the second thread of the loop in place, and the shouldered end of the catch-lever 102 will have become automatically engaged with the catch-pin 100 of the false batten, so that both battens will be ready again for the backward stroke or beat together. The automatic engagement of the catch-lever 102 with the pin 100 is effected by means of aspring 109, arranged on the under side of the main batten 2 and bearing at its free end against one end of the lever 102 at the pivotal connection 104.

From the above it is thought that the construction, operation, and many advantages of the herein-described loom will be readily apparent to those skilled in the art without further description, and it will be understood that changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is

1.
