FEELER MECHANISM FOR LOOMS.

To all whom. it may concern Be it. known that I, Enwann S. S'uMrsoN, oi Hopedale, in the county of Worcester and State of l\'lassachusctts. have invented a new Feeler Mechanism for Looms, of which the following is a specification.

The new feeler mechanism includes a tender of the type which tends to move lengthwise of the bobbin but which is restrained from such lengthwise movement by the weft on the bobbin, the lengthwise, movement occurring when the Weft approaches exhaustion. the feeler then encountering and slipping along the smooth surface of the bobbin. The new feeler mechanism is so organized that it presents a mechanism of simple construction involving but little strain upon the bobbin and preventing any damage to or cutting of the weft.

The new feeler mechanism is illustrated in the accompanying drawings in which Figure 1 is a plan view. In this fi ure the bobbin-leis shown just as the weft rst encounters the feeler tip during the forward swing of the lay. Fig. 2 is a vertical section in the )lane indicated by the line 22 in Fig. 1. big. 3 is a. lan view illustrating the. fpcler and the ho bin in the positions which they occupy when the lay is all the way forward and there is a. substantial amount of. weft on the bobbin. Fig. 4 is :1 plan view showing the relative positions of the bobbin and the feeler when the lay is all the way .forward and the feeler has slipped lengthwise of the bobbin and has moved laterally the controller whirh initiates the action ot' the train of weft-replenishing mechanism. Fig. 5 is a vertical section in the )lane indicated by the line 5-5 1. big. ti. is a vertical section in the plane indicated by the line fi---6 in Fig. 1. Fig. 7 is a vertical section illustrating the rocking support for the front end of the 'feeler. Figs. 8. 9, and 10, are enlarged views of the fceler tipnillustrating, respectively, the initial contact between the'weft and the feeler tip, the tulle-(intact between thcweft and the feeler, tip, and the contactbetween the bare bobbiirand the feeler tipQ Fig. 11 is a vertical section'of the feeler tip Ward endziofqthe feeler arm. 1

a feeler tip B, pivotally connected therewith by pivot screw C, as shownjn Fig. 11. The rear end of the feeler arm is'forked toreceivethe feeler tip. The feeler tip has a plurality of teeth D, (five being shown),'a.nd these teeth are blunt and rounded at their ends so that they do not cut or injure the weft when brought into contact therewith. The feeler ti may be made of metal or of vulcanized fib er such as is frequently used for electrical insulation. loosely and freely-pivoted to the feeler arm and is free to move with respectv to the feeler arm" within the limits determi'ned by the corners E, of the tip and the wall F, of the feeler arm which constitutes a. stopping means for the tip. By reas'ompf these 11mitations to the swing of the feeler tip it can never swing far enough to carry its teeth out of the range of action of the bobbin or weftthe weft H, woundthereon. y reason of the free unrestrained swing of the feeler tip on .the feeler arm unaffected by a spring, the feeler teeth always accommodate themselves to theweft or the bobbin. For example, assuming the ti to occupy the position shown in Fig. 8, at t is first contact between it and the forwardly moving weft, the tip will then swing on its pivot C, as the weft continues to advance so thatnll of the teeth will accommodate themselves to the surface of the weft and uniformly contact therewith, as shown in Fig. 9, andthis irrespective of whether or not the outer surface of the weft is parallel with the surface of the bobbin or not. Likewise. when the bobbin is bare opposite the feelertip, all of the teeth will contact with the surface of thebobbin and slide lengthwise thereof, as indicated in Fig. 10, so that there will be no digging into the surface of the bobbin or merring'thereof.

1e feeler arm A, is mounted on a stationary feeler support J sting of a bracket I, attached to a lateral extension J of the breast beam. A guide K, is swiveled to the forward end of the feelersu ort, turningeon a vertical axis. This gin e has a through-aperture through which front end extends and slides as shown in Figs. Near its rearpend the feeler erm extends through a broad'passogeway or'slot L, of

1, 3, 4, and 7:

The feeler tip is support, as shown in Figs. 3 and 4. The

top of this passageway or guide-slot.

closed by a cap M, as shown in Figs. 1 and 5, thus confining the feelcr arm against vertical movement. Secured to the feeler arm near its middle is a slide N, which slides on horizontal slidcways (l. of the feeier support. This slide screws upon the feeler arm for :uljustment as shown in Fig. 3, and is held in place by not P. A spring Q, surrounds the feeler' arm between nut P, and rock shaft K. and normally holds the feeler arm in its rearward position as shown in Fig. 1, with the slide N, against the s aced lugs R. and S, at opposite sides of tlie passageway L, and with the fecler arm against the rearwardly extending face of the outer lug R, as shown in Fig. 1. In this normal position the feelcr arm extends at an angle to the fore and aft. path of the lay T, and hence is inclined to the longitudinal axis of the shuttle and ot' the weftcarrier. Also, the forward end of the'arm is bent to the right at I as shown in Fig. 1. As a result of this lateral bend of the forward end of the feeler arm and the inclination of the arm to the path of the lay, the weft on the bobbin encounters the feeler tip out of line with the lug R, and the swiveled guide K. In other words, the swiveled guide is offset laterally and outwardly with respect to the feelcr tip so that the bobbin encounters the tip along a fore and aft path nearen the tip of the bobbin than a parallel path intersecting the guide. (onscipientlg an the shuttle in the box at ,the detecting end of the lay moves forwardly, the impact or frontward push of the 'advaneing bobbin on the feelcr tip tendsto move the same longitudinally of the bobbin; and, as illustrated, inwardly away from the butt of the bobbin and toward its tip. As long as the Weft on the bobbin encounters the teeth of the tip, the resistance thus offered prevents any slipping of the tip lengthwise of the bobbin. Accordingly, as the lay at each detecting beat moves forward after the first encounter of the weft with the tip there in no sliding of the tip on the weft; but during, this completion of the forward movement of the bobbin the feeler arm is moved forwardly compressing the springQ, as shown in Fig. 3. During this normal action, there is a slight inward swing. (to the right) of the feeler arm as indicated in Fig. 3 which shows the feeler arm moved inwardly a short distance away from the rearwerdly extending face of the lug B. This normal swing of the feeler arm is permitted because its front end slides in the guide K,

which turns sufficiently to accommodate the i A swing of the teeter arm, and because near its rear end it plays in the slotted rear guide. When the lay retreats the spring Q, carries the fecler arm lmckwardly until the slide l again encounters the lugs R, and S.

In the event, however, that the. weft is, nearly exhausted so that the bare surface of the bobbin encounters the feeler tip, the tip is no longer restrained by contact with the weft but slips along the smooth surface of the bobbin away from its butt and tovard its tip as indiratedjn Fig. 4, the several forward movement of the lay as indicated in Fig. 4, thus carrying the slide N, forwardly of the lugs It, and S, as indicated in Fig. 4. It will be noted that the passageway or slot L, between the hlgs is wide enough to permit this functional swing of the feeler arm. When the lay with the bared bobbin retracts, the-spring Q, rarries the feelcr arm backwardlv and a' depenglingtlug V (Fig. 5) on the slide N, encounters a fixed restoring cam W. on the bracket thereby restoring the feeler arm to. its normal position against the rearwardly extending face of the lugll.

The normal idle poaition of the tip is Such that a portion of the weft still remains on the bobbin, as shown in Fig. -l, when the bared bobbin encounters the feeler tip so that enough weft remains to last until the replenishment of weft has been effected.

The functional swing of the feeler arm un- V der the impact of the bared bobbin on the tech-r tie is utilized to set into actionv the train of weft replenishing mechanism. This train of mechanism includes a controller X, which is mounted in a transverse guidewuy Y, formed in the lugs R, and S, as shown in Figs. 3 and 4, and beneath the cap M, as shown in Fig. 2. The controller has a slot Z (l igs. 2, 3 and 4) through which the feeler arm extends. This slot is sufiiciently wider than the width of the feeler arm, as shown in F ig. 2, so that the normal swing of the feeler arm (see Fig. 3) has no effect upon the controller. When. however, the functional swing of the feeler arm is imparted to it by the lengthwise movement of the feeler tip alon the bobbin due to the impact of the bare2i obbin the controller is slid laterally inwar utilized to bring about weft replenishment. connecting rod 11, is pivoted. at its outer end to the controller as shown in Figs. 3

and 5, and at its inner end it is adjustabl connected with the lowerarm of a. lever 1 (to the right.) as shown in Fig. 4.

This lateral movement of" the controller is This latch is 35 reached 60; restoration movement, the

which is pivoted at 13. to a stationary arm 14. This lever hits a horizontal urn: l5, Figs. 1, 5, and 6, constitutin a litter which "extends beneath a finger 16, of a latch 17. ivoted at 18, to a transmitter 19, which at its forward end is pivoted at 20, to a crank arm 21, fast on the starting shaft 22. This rocking starting shaft corresponds in action and function with the sha ft d of the United States Letters Patent. of

Northrop 529,940, November 27, 189i. The transmitter 19, has a depending foot 23, (Fi 6 resting upon the horizontal surface of tie reast beam extension J. The latch 17, has ada gger 24, (Figs. 1 and 6) which normally is in a. plane below an overhangin hunter 25, on the upper end of the usual well hammer 20. During the normal running of the loom 2 the weft hammer hunter 25, reciprocetes idly above the dagger 24. When, owever, the weft in the running shuttle approaches exhaustion and the bobbin is bared opposite the feeler tip B, with the consequence that the feeler tip under the impact of the bobbin no ,dagger 24, up into the path of the hunter 25.

The weft hammer is so timed with respect to the beat of the lay that this upward lift of the dagger 24, occurs as the weft hammer is moving forwardly and has proximately tie position shown in ig. 6. Durillg the subsequent. forward movement of the weft hammer its hunter 25, encounters the dagger 24,and carries the same forwardly with it, thus likewise moving forwardly the 40 transmitter 19, and the crank arm 21, thereby rocking the startin shaft 22. The rocking of this stortin 5 left brings about the replenishment of the weft in e well known way; as, for example, by the bobbin changing mechanism set forth in said Northro latent No. 529,940. Consequently the we t is replenished before the riuming weft is entn-ely exheusted;

When the weft hammer again moves backwardly the startingshaft 22. and the arm 19,

are restored to their normal positions, as shown in Fig. 6, in any well known way as,

for example, by a spring. such 11$ the spring" c of United States Letters Patent of Nort-hrop No, 529,940, November 27, 1894.

Vlhen the lay moves beckwardly carrying the bobbin beyond the feeler tip, the spring Q, and the cam W, restore the feeler arm A, to the position shown in Fi 1 During this ieeler arm carries the controller X, outwardly (to the left) to the position shown in Fig. 1, and the lifter 15, is flowered. Thereupon the latch 17,

drops by gravity at its rear end thus bringbig the dagger 24, to the position shown in weight so that the spring Q, can be of minimum strength. Art-ordingly only a light strain is brought upon the bobbin due to the import tbereol against the fttlll tip. Also this is the only spring employed in the fi l-lei mechanism. the dagger 2i, dropping by gravity. Consequently, there is no careful adjustment rendered necessary in order that twoor more springs may properly cooperate. This sprin" acts following every deter-ting bent of the R}? to more the feeler roaru'urdly', and after the fevler has been displzu-ed laterally and has initiated the action of the weft replenishing motlianism this spring also acts to move the let-let" laterally to its normal feeling position.

The foeler arm is pivoially supported at its front end remote from the fevler tip. so that it swings through a small are when the tip slips on the bobbin. and through a smaller are during the normal running of the loom. Hence, the tip slips alon the lmltll bobbin with its teeth parallel t. ivi'eto since the concurrent advance of the bobbin cone pensates for the swing of the feeler arm. The bend U, in the rear part of the feeler arm simply increases the lateral ofl'sot of the tip with respect to the rock-shaft thereby increasing the eilect of the impact of the bobbin to displace the feeler arm laterally; and it has no other oliice. The free swing of the tip simply causes the teeth to art-ontoiodute themselves to the surface of the weft and of the bobbin; and it occurs while weft is pres- 'tip slips inwardly along the bare bobbin from the butt to the tip thereof. Hence, when the tip starts to slip it completes its movement, as there is no weft in its path to stop its movement.

'liile this feeler mechanism is intended more particularly for setting into opt-ration a train of weft replenishing mechanism in n bobbin changing loom. it is obvious that it can likewise be employed in a shuttle changing loom or for stopping thetloom.
