WHIP-ROLL-CONTROLLING MEANS.

Application filed February 27, 1914.

T aZ whom it may concern Be it known that I, FRED LAoEY, a citizen of the United States, residing at Lowell, county of Middlesex, State of Massachusetts, have invented an Improvement in lVhip-Itoll-Controlling Means, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to means for controlling the operation and effect of the whip roll of a loom. Various devices have been provided for this purpose, but all have a comparatively limited range of control to adapt themselves to varying kinds of fabric being woven so that it is usually customary either to keep a loom at weaving fabrics of similar quality, or if it be changed to fabrics of different quality to provide whip roll controlling means of different characters, and place upon the loom the proper controlling means, according to the character to be woven.

In the weaving of all characters of fabrics it is highly desirable that during the shedding the whip roll shall have a yielding movement toward and from the warp sheet to compensate for the varying length of the warp extending from the warp beam to the fell, caused by its deflection from a direct course by the shedding. This yielding control of the whip roll is desirable, therefore, in the very light loosely woven fabrics as well as in the very heavy closely woven fab rics, and in those of intermediate character. The resistance of this yielding movement should, however, be correlated to the character of warp being used, that is to say, if the whip roll be held against the warp by a spring the spring should be much stronger for heavier warp than it is for lighter warp.

In weaving fabrics it is important that at the time of beat up the action of the whip roll upon the warp sheet should be such as to secure the proper tension of the warps according to the fabric to be woven. In very light. loosely woven fabrics the warp sheet should simply be held under light yielding tension by the whip roll, for heavier and more closely woven fabrics the yarn tension on the warp sheet caused by the whip roll. should be increased as required, for still more heavy and more closely woven fabrics Specification of Letters Patent.

Patented Nov. 24, 1914.

Serial No. 821,507.

the whip roll should be held rigid against the warp sheet at the time of beat up, and for very heavy and very closely woven fabrics the whip roll at the time of heat up should be rigidly and positively moved against the warp sheet to stretch or put extra tension upon the warp sheet. This action of the whip roll according to the character of the fabric being woven is necessary, as is well understood, in order to secure the proper beating up and prevent the formation of thin places, thick places or stripes.

This invention provides means for controlling the whip roll which when applied to a given loom and properly set or adjusted enables the action of the whip roll to be correlated in the applying of tension to the warp sheet during the shedding, and again (hiring beating up to an extremely wide range of fabrics so that with a single mechanism for controlling the whip roll any given loom may be used for weaving different fabrics extending from very light and loosely woven fabrics such, for example, as scrims up to very heavy and closely woven fabrics, such as corduroys and heavy ducks, or to any two or more varieties of fabrics within this wide range.

The principles of this invention may be embodied by any skilled mechanic in quite a wide variety of mechanical devices, and the invention is not to be limited in its broad scope to particular mechanical devices. There are disclosed herein five different mechanical devices embodying the principles of this invention as illustrative of the invention, but not as restrictive of its limits.

The nature of the invention will appear more fully from the accompanying description and drawings and will be more particularly pointed out in the appended claims.

The drawings show simple and preferred forms of the mechanisms embodying this invention and only so much of the loom as is necessary to an understanding of the invention is illustrated.

In the drawings, Figure 1 is a side view of some of the main parts of an ordinary type of loom with a preferred form of this invention applied thereto; Fig. 2 is a view in cross-section of a detail of the mechanism shown in Fig. 1; Fig. 3 is a side elevation of a portion of the lay sword of a loom with another form of the invention, showing its point of connection to the loom; Fig. 4 is a side view partially in cross-section of the main elements of another form of the invention; Fig. 5 is a side view of the main elements of another form of the invention; Fig. 1 is a side elevation partially in cross section; and Fig. 7 is plan view of a portion of a loom with still another form of the invention attached thereto.

That form of the invention illustrated in Figs. 1 and 2 and which at present is regarded the preferred form of mechanism embodying the invention is shown in connection with an ordinary type of loom in which 1 is the loom side frame, is the cam shalt, the crank shaft, l the lay, 5 and 6 the heddles shown with the shed open, 7 the warp beam, 8 the warp sheet extending from the warp beam through the heddles to the fell 10 the stand for the Whip roll rock shaft, 11 seats in the top of the stand for diiierent positions of the said rock shaft, 12 the whip roll rock shatt, 13 the whip roll rocking arm connected to the shaft 12, and provided with seats 14 for adjusting the position of the whip roll with relation to theshaft 12, 15 the whip roll, and 16 the rocker arm connected to the rock shaft 12 which when operated moves the Whip roll to and from the warp sheet, all of which parts and their general operation and construction are familiar to those skilled in the art. A cam 1? is mounted on the cam shaft at the side of the loom and acts to swing at each beat up of the lay a lever 18 fulcrumed at 1'9 on the loom side. A sleeve 20 is pivotally connected at 2:1 to an intermediate point of the lever 18. 1 link or rod 2 is pivoted at one end at 23 to the rocker arm 16 and at its 01')- posite end 2i slides in the sleeve 20. A set screw is threaded into the opposite end of the sleeve 20 and locked in adjusted position by a lock nut 26. A collar 27 having a depending lug 28 is loosely mounted adjacent the sleeve 20 on the link and a second collar is adjustably mounted by the screw 30 on the link While between these collars surrounding the link is a helical spring 31. ()n the loom side beneath the link is mounted a fixed abutment 32 in the path of the lug 28.

'lhe range of fabrics which may be woven in the loom by a mechanism einl'iodying this invention or which the mechanical devices jtbt described constitute a j'n'et'erred term may roughly be divided into tour main ela In the first class for the lighter more loosely woven fabrics the collar 27 is moved to the right so that its lug 28 engages on, the right hand side of the abutment 32 and the collar is adjusted to such a position along the link as to give the requisite tension of the spring 31 between the collars 27 and 29. In this position the movement of the lever 18 by the cam 17 will notaffect any movement of the link 22 so that the only tension applied to the warp sheet y the whip roll will be that due to the particular tension of the spring 31. Under these cii ,umstances the whip roll is held in yielding engagement with the warp sheet at the time oi beat up during the shedding, and also at the time of heat up. In the second class, for heav ier and more closely w 0 en fabrics the collar 27 placed with its lug 28 to the left of the abutment 32 so that the collar 22 abuts the sleeve 20 and is held thereagainst by the spring 31, the tension of the spring 31 being adjusted to the requisite amount by adjusting the collar on the link 22. The set screw 25 is set hack to the left so that it will not at any time contact with the end 24 of the link Under these circumstances during the shedding the whip roll will be held against the warp sheet by a yielding action depending upon the tension of the spring 31, and at the time of heat up this yielding action will be increased by the n'iovement oi the lever 18 carrying the sleeve 20 along on the link and comprising the spring 31. In the third class or the still more heavy and more closely woven fabrics the parts Will be arranged as last described excepting that the set screw will be so adjusted as to be brought into contact with the end 24 of the link 212 at the time of beat up so that in this case at the time of beat up there is no spring or yielding action but the whip roll is brought rigidly and solidly against the warp sheet. In the fourth class or the heav iest and most closely woven fabrics the adjustment of the parts is as last described, excepting that the set screw 25 is still further screwed into the sleeve 20 so that at the time of heat up the parts are not only held rigid but the rod :22 is given an extended movement, thus causing the whip roll acting rigidly against the warp sheet to extend or put an increased tension thereon at the time oi beat up. It will thus be seen that the amount ot yielding action during the shedding in all of the classes of fabrics may be varied by varying the position of the collar 2t! and that the amount of yielding action during the heat up in the first two classes may be varied in the same manner, all in addition to such, variations as are provided by shifting the whip roll. in the seats l and the rock shai't 12 in the seats 11. his single mechanism, therefore, provides 101' an almost infinite variety of conditions enabling the loom in a sinij'ile manner readiiy and quickly to be adjusted under an extreme range of conditions to the proper control of the warp sheet by the whip roll during the s ihedding and during the beating up.

Another form of the invention is illustrated in Fig. 3 in which 33 represents the lay sword of a loom pivoted at 3%, the whip roll being indicated at seated in the rocking arm 36, carried by the shaft 37, having depending therefrom the rocker arm 38. A lever 39 is fulcrumed at 40 on a bracket 41. secured to the loom side and is connected at its lower end by a link or actuator rod 42 to the lay sword at a point above its pivot so that the lever is moved upon the beat up. A rod or link 32 is pivoted at 44: to the rocker arm 38 and has its end sliding through a sleeve 46, and through a loose bearing 47 formed at the right hand upper end. of the lever 39. A set screw 48 is threaded into a bearing 4-9 in the left hand upper end of the lever 89, alines with the rod l?) and is locked in adjusted position by the lock nuts 50. The sleeve 46 is mounted to slide in a bracket 51 secured to the loom side and a set screw 52 passing through the bracket enables the sleeve 46 to be locked against movement. A collar 53 is adjustably secured by a set screw 5i to the rod 43 and a helical spring surrounding the rod l3 abuts against the sleeve 46 and the collar The operation of the construction thus illustrated in Fig. 3 is quite similar to that shown in Fig. 1 for the first class of fabrics, the sleeve 46 will be moved to the right out of the path of the lever 39, and locked in position with the set screw 52; for the second class of fabrics, the sleeve l6 is left free to slide in the bearing 51 and the set screw 48 is adjusted to the left so is at no time in contact with the end of the rod 5 3, while the lever 39 at the time of heat up moves the sleeve 46 to compress the spring l9; for the third class of fabrics the set screw 48 is adjusted to the right so as to contact with the end 45 of the rod 4-3 at the time of beat up; and for the fourth class of fabrics the set screw l8 is adjusted still farther to the right so as to give a positive and extended move ment to the rod at the time of beat up.

A third form of the invention shown in Fig. 4 is quite similar to that last described. l he lever 56 fulcrumed at 57 to the loom side is operated by any suitable means such as the la sword or a cam or other properly timing and moving part. The rocker arm for the whip roll shaft is shown at 58. The rod 43 is pivoted at ll to the arm 58 and slides freely at 59 in the upper end of the lever 56, passing midway through a bearing 60 secured to the loom side. A sleeve (ll is mounted to slide in the bearing 60 and a helical spring (32 surrounds the rod -13, abuts against the sleeve 61 and the collar 63 adjustably secured by the set screw 64 to the rod 43. A sleeve 65 is fitted over the rod 43 and the left hand end of the sleeve 61, and is adjustable longitudinally with respect to both, and may be locked to either or both by means of the set screws 66 and 67. The operation of this form of mechanism will be apparent. For the first class of fabrics both set screws 66 and 67 are unlocked so that the sleeve 61 is not moved by the lever 56, and the only action upon the whip roll is that due to the spring For the second class of fabrics the set screw 67 locks the sleeve (55 to the sleeve 61 in the required longitudinal position so that at the time of beat up the lever 56 moves the sleeve 61 to compress the spring For the third class of fabrics the sleeve 65 is locked by the set screw 66 to the rod 43 in such position that at the time of beat up the lever 56 will through the rod 43 hold the parts rigid. For the fourth class of fabric the sleeve 65 is locked by the set screw to the rod 43 in such a position that at the time of beating up an extended movement will be given the whip roll.

A fourth form of the invention. suflieiently illustrated in Fig. In this form l6. ers G8 symmetrically located at opposite sides of the loom frame, operated at the beat up through connections with the lay sword or cams or other suitable means and are fulcrumed at (is on the loom frame. The whip roll 70 is journaled in bearing blocks 71 mounted to slide in ways formed in longitudinally adjustable bearing frames 72. These bearing frames are adjusted by means of set screws 73 passing through the overhanging flanges Tl of brackets 75 se cured to the loom sides, these flanges Tl being slotted for that purpose. Blocks 76 are mounted to slide in the ways in the bearing frame T52 and are provided with epi iositcly extended lugs 77 which project into the path of the upper ends of the levers .38 whicl are forked for that purpose. Set screws 78 pass freely through the closed. or left hand end of the bea ing plate 72 and are locked in ad usted position by the lock nuts 79. Lugs 80 project from the bearing blocks 71 and helical springs 8i surround the opposing ends of the set screws 78 and lugs 80. In the first class of fabrics the barring plates 72 are adjusted to the right on the bracket 75 and locked by the set screws 73 in such position that the block 76 will abut against the left hand. ends of the bearing plates 72 and the lever 68 when vibrated will not strike the lug T7, and the set screws 2'8 will be retracted so that the tension of the spring 81 will alone be opposed to the movement of the whip roll. in the second class of fabri-cs the bearing plate 72 will be adjusted to the left in such a position as shown in Fig. 5. but with the set screws 78 retracted so that as the levers (")8 vilrate at the time of heat up they will strike the lug 77 and compress the spring 81. In the third class of fabrics the set screws 78 are adjusted to the right so that at the time of heat up when the blocks 76 are mo ed to the right the set screws 78 will contact with the lugs 80 at the end of the movement and the parts will. be rigid. In this construction reliance is had upon the fact that the tension on the warp sheet will keep the whip roll and its bearing block Tl somewhat to the left of the extren'ie position. In the fourth class of fabrics the set screws 73 are still farther adjusted to the right so that at the time of beat up not only are the parts rigid but another extended moiement is given while rigid to the bearing blocks carrying the whip roll.

A fifth form of the invention is illus trated in l igs. 6 and 7. Therein a rigid shaft 812 is provided suitably supported in brackets or stands at the loom sides, The crank shaft of the loom is indicated at 84 on which mounted a cam or eccentric 85. The wrip roll 86 rests in one of the seats is? of rocking arms 88. The rocking arm $13 as shown in Fig. 7 forms one end of a bell cranl: lever, the other arm of which 8 is offset and is provided with a plurality of seats 3t. This bell cranl: lever is journaled on the shaft A rocker arm 91 is provided with the sleeved hub 92 by which it adjustahly secured on the shaft 82 by a set screw vhile its free end projects in the path of the eccentric An arm ill is journaled on the sleeve 92 and may be locked. thereon in desired rotary adjustment by the set screw 83. This arm 94 is forked at its free end A rod 96 provided with a loop or hook at its upper end is hung in one of the seats 90 of the arm 89. A sleeve longitudinally slotted at 98 on one side mounted on the rod 96 and a collar 9% on the sleeve with a set srew 100 threaded into the collar passing through the slot 98 and abutting against the rod 96 so that the collar and the sleeve may be loclred in any des red position relatively to each other and to the red A helical spring 101 surrounds the sleeve 97 and abuts against the collar 99 at the bottom and a washer 102 resting agiinrt the 'l'orlzed arm 9e: at the top. the rod 93 passing up through the forked end of said arm ill. In the first class of fabrirs the rocker arm 91 is swung out of the path of the eccentric 85 and locked to the shaft by the set screw 93. the arm ill is then locked in desired position by the set screw 95, the slee e 97 is dropped down and the collar 99 and sleeve 97 locked to the rod 96 to give the desired tension of the spring 101. The whip roll will then be controlled entirely by the spring. In the scmmd class of fabrics the rocker arm 91 is brought into the path of the eccentric R5 and the arm 9 t is locked by a set screw 95% to the sleeve 9:2. the set screw being withdrawn. he sleeve 97, collar 09 and spring llll are adjusted as before. Then, at the time of beat up the eccentric 85 through. the rocker arm 91 and arm 9i compresses the spring giving the desired increased tension. in the third class of fabric the adjustment is as last described excepting that the slee e 97 is slid up and locked on the rod W3 in such a position so that at the time of la t up its upper end will be struck by the washer 102 beneath the forked end of arm fl l, thus giving the desired rigidity. In the 2th class of fabrics the adjustment is as last described excepting that the sleeve 97 is loelred in a still higher position so that at the time of heat up an extended rigid movement is given to the parts putting the desired increased strength or tension in the warp.
