Application and August: as, 1916.

To all Elf/L01 may (Zone/Wu Be it known that I, Anonzo l0. fliliioAnns. and r sident. oi l'lOPOtlttlO, county of l l orcester, State of Massachusetts, have invented an improvement in Feeler lllechanisiii. tor l'looms, of which the following description, in eonnection With the accompanying drawing, is a specification, like characters on the drawing This invention relates to iluprm ezuents in automatic looms in which the fecler enters theruuning shuttle to feel upon the filling carrier therein and upon detection of substantial exhaustion of filling initiates the action oi inechanisn'i which etiects a change in the operation of the loom, such. as the suh- .stitution of a fresh filling carrier for an e2- hausted one, or serves to stop the loom.

Lin usual loom constructions the footer enters the shuttle box through the front wall, thereof and operated by contacting with upon the filling carrier upon. the heatt up oi? the lay. in. such case the binder which arrests the shuttle is usually located at the rear side of the shuttle box and d1" verts the shuttle away from the plane of it enters the shuttle hot.

In making hard "weaves, particular-l7, upon Wide loonis it is found that the loom Will act more effectively ii the shuttle is not inverted .;in this inanner away from the plane of the (Ti the shuttle. tho l vid reed, it is desirable therefore that the shuttle bones be equipped with front binders. lVhen therefore, the usual teeler is employed it is necessary to cut an. aperture through the front hinder and inasmuch as the shuttle engaging surface oi: the hinder is curved, the edges of the walls of the a 'ie'rture Wear away the shuttle quite rapidlyv The ohjeet, oil? the present invention is to provide a looin having -Front. hinders with feeler mechanism which will not necessitate the cutting; of an aperture through the binder. This accon'iplished in the preferred einliiodiment oi the invention illustrated herein by mounting the teoler upon the lay and so iiiositiou 1,; the same that it, enters the rear sill.

illustrate a 'n'eferred enihodinientof my invention applied to an automatic filling replenishing loom but it will he understood that the teeter may be utilized to eti ect other changes in the operation of the loom such as the stoppage thereof.

In the drawings;

l igure 1 is a plan view of the end of the loom frau'ie including the breast beam and shipper plate and a section of the end of the lay and. shuttle box carried thereby showing the improved tleeler mechanism applied thereto Fig. 2 is an end. view showing the t'eoler mechanism applied to the loom and illustrating the shuttle hon, carrier in section,

Fig. 3 is a Front elevation of the standard which supports the transmitter operating; lever, a portion of the end of the trans initter and its hearing being shown.

'llhe invention is illustrated herein as appliedv to the Northrop type of automatic titling replenishing loom-Which is providml With transferring niechanisni tor autouiatieally thrusting; a fresh filling carrier into the running shuttle and ejecting the used rarrier thereto-one said transferring. mechanism being controlled by the usual controller shaft having a latch adapted to he positioned in the path of a moving actuator upon call for transfer and operated. by said moving actuator to cause the proper operation of the trai'isterring mechanism.

Inasmuch as these mechanisms are well known. their illust 'ation is tlIHlCCGSL-HUTV, so that; only a portion of the end frame of the loom sl'io'wil'ig the feeler and the nit-ehai'lisuis with which it innnediatel cooperates are illustrated in the drawing.

The drawing illustrates the end ot the shuttle and filling till ltlti l i, it

The usual controller shaft. 6 is provided with an arm having a bifurcated end 7 in which the end of a latch 8 is mounted, the opposite end ,of said latch preferably lying normally in the path of a moving actuator 9 such as the weft hammer. -These mechanisms may be and are of usual construction.

The latch 8 is adapted to be moved out of operative relation to the moving actuator 9 by a suitable transmitter which is actuated by the feelcr mechanism in a manner hereinafter to be described.

The shuttle boxes 10 are preferably provided with relatively thick rear walls 11, and the binders 12, which may be of a usual type, are carried by the front walls, so that as the shuttle 13 is arrested it is pressed against the rear wall of the shuttle box and its path of flight directed closely adjacent the reed.

The shuttle may be equipped with the usual types of filling carrier employed in filling replenishing looms, but preferably is provided With a bobbin 14 having a feeling slot 15 in its barrel adapted to receive the.

feeler upon. substantial exhaustion of the filling upon the bobbin.

In order to avoid cutting through the binder and thereby weakening the same and causing it to present edges which wear the shuttle, a novel feelcr mechanism is provided in which the feeler enters the shuttle throughthe rear wall of the shuttle box, the

. feelcr-supporting mechanism preferably being mounted upon the rear wall of the shuttle box.

In the preferred embodiment of the invention shown herein the feelcr is in the form of a rod 16 slidably mounted in an aperture 17 in the rear wall of the shuttle box, and is pivotally connected at its outer end to the lower end of a lever 18. The lever 18 is provided, intermediate of its ends, with a hub which is mounted upon a stud 19 projecting laterally from a stand 20 suitably secured to the'rear wall of the shuttle box. The stand 20 is provided with an upward extension 21 having a guide 22 for an arm 23 which is pivotally connected to the upper end of the lever 18. The pivotal connections between the lever 18 and the feelcr 16 and arm 23 respectively have sutlicient play to permit the slight arcuate movement of the lever 18 without causing the feelcr or arm to bind in their guides 17 and 22. i

In prder not to interfere with the flight of the shuttle it is necessary that the feelcr shall be normally Withheld from feeling position and this convenientlyis accomplished by a spring 24 preferably encircling the hub upon the lever 18 and anchored at one end to a pin on the stud 19 and at the other engaging the lever 18 in such a manner as normally to remove the feelcr from feeling position, a stop 25 being provided upon the extension 21 of the stand 20 to limit the movement of the lever 18 under the action of the spring 24.

The mechanism which cooperates with the feelcr thus described preferably comprises a lever 26 having a central hub pivotnlly mounted upon a stud 27 projecting laterally from a stand 28 which desirably is adjustably secured by a bolt 29 to a flange 30 depending from the end of the shipper plate. the lever 26 being provided at its upper end with a member 31 pivotally connected to the lever 26 and extending through a guide 32 in an extension 33 of said stand. so that the end of the member or arm 31 is in alinement with the end of the arm 22% of the feelcr mechanism.

A screw 33 seated in the end of the arm 31 and adapted to be secured in adjusted position therein by a lock nut 3. provides means whereby the cooperative relation of the members 31 and 23 may be regulated to adapt the feeler for use with filling carriers of dilferent diameters or with shuttles of different width.

A spring 35 anchored at one end to a pin on the stud 27 and encircling the hub of the lever 26, and at the other end engaging the lever 26 serves normally to rock the upper -end of the lever 26 toward the feelcr incchanism and its movement in that direction is limited preferably by a stop 37 projecting from the extension 33 of the stand 28 into the path of the upper portion of the lever.

The lever 26 is operntivcly connected at its lower end to a suitable transmitter which is adapted to move the latch in relation to the n'ioving actuator under the control of the feelcr mechanism upon detection by the feelcr of the condition of the filling upon the filling carrier.

A preferred form of transmitter which is illustrated herein comprises a rock shaft 38 mounted in bearings 39, 10 in the end of the yoke 41 which has an upwardly extending flange 4-2 adjustably connected by a bolt 43 with a lug or flange 4 1 extending upwardly from the shipper plate 2.

The rock shaft 38 is provided atone end with a crank 15 which is pivotnlly connected to the lower end of the lever 26. At its opposite end the rock shaft is provided with an offset portion or crank 46 which engages a suitable slot 47 in the end portion of the latch 8.

\Vhen the rock shaft or transmitter 38 is oscillated by the movement of the lever 26 it serves to shift the position of the latch relatively to the path of the end of the moving actuator 9 as is usual in automatic loom constructions. In some instances the'latch is normally maintained in the path of the moving actuator and removed therefrom so long as the fcel'tlr engages the filling upon the filling carrier and remains in the path to oscillate said lever to advance the feeler to feeling position and itself operable by saidlever upon engagement by the feeler with filling upon the filling carrier to prevent a change in the operation of the loom butoperating upon detection by the feeler of substantial exhaustion of filling upon the filling carrierto effect a change in the operation of the 100m.

6. In an automatic loom a feeler mounted upon the lay and positioned to enter the rear side of the shuttle box and feel upon the filling carrier in the running'shuttle, a spring actuated lever connected at one end to said feeler and normally acting to Withhold the feeler from feeling position, an-

arm connected to the opposite end of said lever, yieldable means carried by the stationary part of the loom adapted to engage said arm and advance the feeler to feeling position and operable by said feeler upon engagement by the latter with the filling upon the filling carrier to prevent a change in the operation of the loom but operating upon detection by the feeler of substantial .exhaustion of filling upon the filling carrier "opposite end of said-lever, means comprising a spring of greater strength than that of the spring for the feeler actuating lever adapted toengage the feeler actuating lever upon the beatup ofthe lay whereby the feeler is advanced to feeling position and upon engagement with the filling upon the filling carrier causes the actuation of both of said levers in the opposite direction. and means operable by said means to avoid the action of the transferring mechanism but adapted upon detection by said feelerwf substantial exhaustion of filling to effect the change in the operation of the loom.

8. In an automatic filling replenishing loom comprising a transferring mechanism and means for operating the same including a controller having a latch adapted to cooperate with a moving actuator, a transmitter engaging said latch, means for operating said transmitter comprising a lever having a spring acting normally to maintain said latch in operative relation to said moving actuator, a feeler mounted upon the la y and positioned to enter the rear side of the shuttle box and feel upon the filling carrier in the running shuttle, a spring actuated lever connected at one end to said feeler and at its opposite end to an arm positioned in operative relation to a member carried by the transmitter operating lever whereby upon the beat-up of the lay the engagement of said member with the arm upon the fe'eler actuating lever will advance the feeler to feeling position and upon engagement with the filling on said fillingcarrier and upon further movement will actuate said levers and said transmitter to remove the latch fronrthe path of the moving actuator but upon detection of substantial absence of filling will permit engagement by said latch with the moving actuator to cause the action of the transferring mechanism.

9. In an automatic filling replenishing loom comprising a transferring mechanism and means for operating the same including a controller having a latch adapted tocooperate with a moving actuator, a transmitter comprising a rock shaft having an offset end engaging said latch and provided at its opposite end with a crank, a lever pivotallv mounted upon a stationary portion of the loom frame connected to said crank. a spring engaging said lever and normally acting to retain said latch in operative relation to a moving actuator, a member connected to the opposite end of said lever overlying the path of the lay, a feeler mounted upon said lay to enter the rear wall of the shuttle box and feel upon the filling carrier in the running shuttle, a spring actuated lever connected at one end to said lever and operating normally to withhold the feeler from feeling position. an arm connected to the opposite end of said lever adapted to engage said member upon the beat-up of the lav whereby upon said engagement of said arm with said member the feeler will be advanced to feeling position and upon engagement with the filling upon the filling carrier will actuate said transmitter operating lever and transmitter to remove the latch from the path of the moving actuator and upon detection of substantial exhaustion of filling will permit the latch to remain in the, path of the moving actuator thereby causing the action of the transferring mechanism.

in the running shuttle, a spring actuated lever connected at one end to said feeler and at its opposite end to an arm positioned in operative relation to a member earned by an it I the transmitter operating lever whereby upon the beat-up of the lay the engagement of said member with the arm upon the feeler actuating lever will advance the feeler to feeling position and upon engagement with the filling on said filling carrier Will actuate said levers to remove the latch from the path of the moving actuator and upon detection of substantially absence of filling will permlt 10 engagen'i'ent by said latch of the end of the operate properly with bobbins of different I size.

In testimony whereof I have signed my name to this specification.
