FEELER MECHANISM FOR LOOMS.

Application iled March 30, 1926; Serial No. 98,517.

This invention relates to feeler mechanisms for looms whereby the operative condition of the loom is changed upon substantial exhaustion of the filling in the shuttle.

It is now the ordinary practice to provide fillin carriers with a preliminary winding of fil ing, or a bunch, so called, to cooperate with a feeler to call for a change in the loom operation, such, for instance, as replenishment of filling "or loom stoppage, when the feeler detects a substantial exhaustion of the filling comprising the preliminary windings or bunch. Since the feeler is to be controlled as to its functional operation by the amount of filling remaining in the preliminary windings or bunch, `much uncertainty results as to the amount of filling remaining on the filling carrier when replenishment is effected. The amount of filling remaining on the filling carrierwhen it is ejected from the shuttle constitutes waste and for economic reasons should be as small as possible consistent with laying a full pick of filling in the shed under proper tension on the last flight of the .shuttle preceding replenishment. n One of the objects of the present invention, therefore, is to provide for a minimum amount of waste on filling carriers when they are ejected from the shuttle, and to this end the invention consists primarily in providing the filling carrier with two bunches, spaced apart longitudinally of the filling carrier, to permit the feeler to engage the filling carrierbetween the bunches on a detecting beat, and to be held from functional operation to call for a change of filling until one of the bunches has been depleted. Under these conditions it is apparent that one of the bunches may be formed of a predetermined amount to constitute the wastage remaining on the filling carrier when it is ejected, while the other bunchlwill constitute a reventer bunch to prevent the feeler from ca ling for achange of filling until the filling in the reventer bunch 'has been depleted. In t ese respects the present application is a continuationin part of a rior application Ib the same inventors, Seria No. 17 ,068, filed lll/larch 20,. 1925.

In accordance with the present invention, the filling carrier, as above stated, is provided with a main or wastage bunch and a preventer bunch, separated longitudinally of the filling carrier to vprovide a space between the bunches for engagement of the filling carrier or bobbin by a side sli ping feeler when the working supply of Alling between the bunches -has been depleted, the preventer bunch acting at such times to prevent side slipping movement of the feeler to call for a change of filling until the filling constituting the preventer bunch has been woven into the cloth, and thereupon, permitting the feeler tofunction and call for a change of filling.

The invention and new features thereof will best be made clear from the following description and the accompanying drawings of one good form thereof.

In the drawings:

Fig. 1 is a perspective view at the feeler Jide of a loom containing the present inven- Fig. 2 is a top plan view showing the re-l lation of parts when the feeler engages a working supply of filling .between the bunches on the filling carrier;

Fig. 3 is a similar view showing the relation of parts when the filling between the bunches has been depleted and the preventer bunch is acting to prevent side slipping movement of the feeler;

Fi 4 is a view similar to that of Fig. '3 showing the fillingv yon the preventer bunch as having been partially exhausted but still acting to prevent side slipping movement of the feeler; and

' Fig. 5 is a view simliar to that of Fig. 4 showing the preventer bunch as having been exhausted and the feeler freed to its side slipping movement.

In the form 0f the inventionherein shown the feeler is associated with a train of mechanism for calling for replenishmentof filling when the filling on the preventer bunch has been depleted, but the replenishing mechanism is not herein shown because the details thereof form no part of the present invention and such mec. auism may be of any usual or preferred type now well' known.

,July 22, i925, but in the present epplicem tion no claim is mede herein for the structural features' of the feelen'since such claims already form the subject-metter of the pending application above mentioned.

The loom frame l. may be of any desired Construction, and rising Jroin the usual transverse shaft is the erm 2 to which is pivoted et 3 the actuator i the rear end portion of which is provided with e housing 5 having en. opening 6 into which muy be projected en operating member herein con stituted as part connected to the cam til Jfollower.. Pivotelly mounted on lugs F3 eirtending from the housing 5 is e, lever 9 to which is connected the actuator 10, the other end portion of which entends into the opening l1 in the ieeler stand. rlhese parts are herein shown as of the seme type end con struction es those more fully illustrated and described in the copending application above mentioned but it is to be understood that so far as the present invention is concerned, such transmitting mechanism lto cell for a, change of filling under functional opera,n tion of the Jfeeler may be of any suitable character,

Extending from the loom freine is the shipper stand 12 to which is secured by e bolt 13 e bracket lll supporting the feeler stand The ieeler 16 has the toothed or roughened end portion 17 and is mounted on the teeler stand 15 for movement towards and from the iront oft the loom. and also in a direction longitudinally of the shuttle. The teeler 16 has the laterally extending portion 18, the toe lll-ot which is adepted to engage n stop. or lug 2O carried by the feeler stand. Connected to the leterel extension 1.8 is e. spring 2l which muy be secured et one end to the leterel extension by aA bend, es et 22, end 'the other end of the spring moy be secured to e projection 23 et the rear of the iieeler stond, the construction being such tliet the normnl tendency of the spring 2l is to move the eeler rearwardly to its full feeling position and yet permit side swipe movement ofi the feeler.,

lt will not be necessary 4herein to more fully describe the construction end operetion ot the ieeler lil since this mechanism is shown es substantially the seme-es that in the :3o-pending application, Serial Nd 45,349, end the structural details thereof form no part of the present invention, because so fer es the present invention is concerned any iceler of the side swipe type may be used.

The ley 24 is provided with the usuel Loodsen shuttle bei; 25 for the reception ci the shuttle 2d in which the filling carrier 27 is mount-ed, and the front wall of the shuttle boxv is provided with en opening 28 which registers with a similar opening 29 in the front well of the shuttle when the letter is construction being such that on e detecting beat the l'eelerenter the shuttle and feel for the lling.

ln accordance with. the present invention, the filling carrier 27 is provided with the usual heed 30 by which the filling carrier may be detechebly held in the shuttle by the usuel holding' jews 3l carried by the shuttle. The filling carrier 27 hns a mein or westege bunch of filling 32 which in the present instance is shown es wound upon the fillingv carrier 2l" adjacent the head thereof, and it also hes wound thereon e, preventer bunch 33 sepereted from the main or wastage bunch 32 by e, space 34, Fig. 2, suiicient in extent to permit the end of the side swipe feeler to engage the filling cerrier between the bunches when the working supply of filling between the bunches has been withdrawn.

The feeler, in the present instance of the invention, is shown es of the type wherein it is given its side swipe movement by the frontwsrd pressure et e surfece within the shuttle, such,'fory instance, as the surface of the filling carrier 27, and when the filling between the two bunches hes been depleted and the ieeler engages the filling carrier between the bunches, the normal. tendency crt the frontwerd ressure of the filling carrier is to cel-use si e swipe movement o'i the teeler. (living, however, to the preventer bunch 33, o struction is presented to such side swipe movement, und such obstruction continues to be presented to the eeler on detecting beats until such obstruction is removed. b depletion of thc lling in the preventcr ldunch. in Fig. l the filling in the preventer bunch is shown es partially depleted, but still the obstruction to the side swipe movement 1s p resented to the ieeler, until wheny the ilhng in the preventer bunch is entirely exhausted., es indiceted in 5, the feeler is freed to its side swipe movement to initiate filling replenishment.

Since the :teeler pertelres of its side swipe movement when the illing in the preventer bunch here been depleted, it is obvious that the emount oit filling in the mein or westege bunch be oi predetermined amount and is preferably oi en amount sucient to per-- mit e lull length oi iilling to be luid in the shed under proper tension after. the filling in the preventer bunch, has become exhausted. 'lihus the amount of wastege remaining on the filling carrier when it is ejected from the shuttle can be predetermined end miniw Sli] mized to an amount sufficient only to p'ermit a full pick of filling to be laid in the shed under proper tension on depletionof the preventer bunch.

Applicants believe themselves to be the first in the art to provide a feeler mechanism 'connection with such filling carrier having a main or wastage bunch and a preventer bunch spaced therefrom, a side slipping feeler held from side slipping movement by the obstruction offered by the preventer bunch until the filling thereof has been de leted, thereupon freeing the feeler to its si e slipy ping movement. It is to be understood, of

course, that the filling constituting the main or wastage bunch andthe preventer bunch is continuous, so. that when the filling of the preventer bunch has been depleted, the filling in the main or wastage bunch will be laid in the shed.

While the present invention 'has been described in connection with a filling carrier or bobbin having two bunches'wound thereon with a space between, which is a simple and preferred form, yet it is to be understood that the filling carrier of the present invention may have any desired number of bunches as more fully disclosed in the a'p-v plication Serial No. 17,068, before mentioned, and of which this is a continuation in part.
