FILLIliTG-FEELER-MECHANISM FOR AUTOMATIC LOMS.

1&20560, specification of Application filed July 12,

To all whom it may concern.' 4

Be it known that I, ONESEME LANDRY, a

' citizen of the United States, residing at- New Bedford, in the county ofBristol and State of Massachusetts have invented c ertain new and useful Improvements in Fillv ing-Feeler Mechanism for Automatic Looms,

- mittent action for ascertaining, at intervals,

I attached to the front .shaft of the loom.

the condition of the supply of'yarn on the bobbin or cop so that constant or continuous engagement with the bobbin yarn, together with the incidental wear -and tear, is obviated.

The invention further resides in the features of construction and the arrangement and combination of parts hereinafter described and claimed, reference being had to the accompanying'drawings; wherein- A,Figure 1` is a fragmentary top plan .-view of the improved mechanism;v Figure 2 an end elevation thereof; Figure 3 an enlarged plan view of the feeler device; and

Figure 4a detailed elevation of thejarm laid, by the passage ofthe shuttle, `.up

against thepart of the cloth already wovenL Referring'- to the accompanying drawings, a holder 1 is secured to the` bracket of the loom which holds the shipper handle and slidably supports a feeler support 2 which 'is urged` outwardly by a coiled spring; .3

housed within the guideway land chamber 4Q- of said holder. A feeler '5 is pivoted to the slidable support 2 by .a bolt 6 about which a coiled spring 7 encircles for urging the feeler to be left in Figure 3. The outer end Letters Patent. Patented JT une 20, '1922.

of the feeler is curved in the opposite directionI and formed on its outer side'with ser. rations 8 which are designed to catch in the yarn 9 on the bobbin orecop 10 --and hold the feeler from-riding off to the right about its pivot. The inner-end 11 of the feeler,

`here depicted as a detachable part, constitutes an inwardly extending feeler 'finger which, when the supply of yarn on the bobbin-is substantially or altogether depleted, will be swung tothe left" b'y reason of the feeler 5 contacting directly with'fthe body of said bobbin and riding off the same to the right 'since there, is no yarn for thel ser' rations to engage in.

ative position, the feeler finger v11 is disposed in the path to 'engage a lug 12 when the feeler su port is pushed inwardly by.

the bobbin. ug `12 is carried 'on one end of a lever 13 that is pivoted intermediate its ends and has its opposite end engaged in -a curved slot 14 of an armv l5.V This arm is attached to the shaft 16 at the front of andis a part of cop.v The curve of the feeler is so arranged thatfas long as there is yarn on the'bobbin for cop, the point of contact between the f feeler and the yarn will be back from the point ofthe feele'r,'causin,'g the serrations to engage in lthe yarn andl the `feeler to be pushed back .with its support without rocking on the 'stud 6. The feeler finger 11 will thus be held out of the 'path of and out of contact with the lug 12 on the rod 13. When the yarn on the bobbin or cop is reduced to a minimum'point the end of the feeler will strike on the hard body of the bobbin or cop and ride` thereoifto swing the feeler on its stud and move the feeler finger to the left where it will contact with the lug l2 on the rod asl thesupport 2 is moved backwardly. This causes the rod to swing on its pivot '17 and theouter end to raise the arm 15 by moving in the curved slot 414:. The raising ofthis arm brings it incontact with the lay of the loomv which forcesit back, giving a movement to the shaft to whichit is connected,4 and this shaft A By this swinging movement to an oper is connected to a, system of levers which Vactu-ate the filling change mechanism 4in the and automatic in operation.

also, can be applied tothe specified type of.

battery, not shown. p

If the feelcr were permitted to make a {contactwith the yarn for every two picks of the loom unnecessary wear, both on the yarn and on the mechanism of the feeler, would occur. Therefore, 'mechanism has been provided to hold-the feeler'out of contact for a definite period, as for instance sixty picks, which period can be varied for,l any number required, then permit the. feeler pawl carries a pin 2,2' extending verticallyl downward. `A horizontal shaft 23 is provided on oneI end with,y a gear 24 that is dri-ven by gears not shown, from the mechanism of the loom and on the opposite end ,with radiating pins or arms 25 which contact with the trip or pin 22 causing-the pawl to release the feeler. The spring 3 then brings the feeler into contact with the bobbin yarn. By lthe time the pin 25 has released the pawl the latter springs back into engagement with the teeth of the slide and holds the feeler out of contact with the yarn and bobbin. v rlhis period of contact can be governed by the time of contact of the two pins and is usually setfor two picks of the loom. i L i rlhe construction is exceedingly simple The device,

1 loom without 'material modification or reconstruction of the latter. The feeling is predetermined, very -sensitive and can be for longer or shorter rest periodswith corresponding shorterand longer `active periods.

rlhe feelers at present in use can notbe adjusted fine enough to work unless there is somesmall amount of yarn on the bobbin,1

pivoted on a ver-Y and thisyarn is all wasted; the present improvementscan be vadjusted to work when there is the last layer of yarn on the bobbin,

thus saving the waste.` Furthermore it will p 'work'equally well on- .wooden bobbins or paper cops. l

The feeler can nbe arranged at either end of the loom.

1. In a f eeler device for looms, a supportA having a guideway, a spring-tensioned slide in the guideway, afeeler pivoted to one e'nd of the slide and. extending outwardly therefrom, ratchet teeth carried by a side of the slide, a pawl pivoted between its ends and f having one end lengaging the ratchet teeth and having a project-ingpart on its opposite end andan intermittently rotating element having spaced projections for successively acting on, the projecting part of the pawl to move the pawl .out of engagement with the ratchet teeth at predetermined intervals.
