To all whom it may concern:

Be it known that l, Errzi H. Rrox, a citizen'of the United States, residing at lVorce ter, in the county of \Vorcester and State of Massachusetts, have invented certain new and useful Improvements in F filing-Detector Mechanism for Tet't -Replenishing Looms, of which the following is a specification.

My invention relates to a filling detector mechanism for a weft replenishing loom, and particularly to a mechanical filling detector mechanism having a feeler, which is preferably located at the magazine end of the loom, and which is adapted to enter, through an opening in the shuttle box and the shuttle, to engage the filling on thebobbin in the active shuttle, as the lay moves forward, and on the substantial or practical exhaustion of filling in the active shuttle, to operate mechanism connected with the weft replenishing mechanism, to cause a fresh bobbin to be supplied to the active shuttle in place of the substantially exhausted bobbin, in the usual and well known way.

The object of my invention is to improve upon the construction of a filling. detector mechanism of the class referred to, and more particularly to provide a filling detector mechanism having a feeler, which will feel for'and detect the practical or substantial exhaustion of filling on the bobbin, without regard to the size of the bobbin on which the filling is wound. or the position of the bobbin in theshuttle.

In my improvements 1 provide a spindle having a head adjustably fastened on said spindle, which is loosely held in a horizontall; extending sleeve; said head is adapted to yieldingly engage the filling on the bobbin A second head is loosely held in a recessed portion in the first men tioned head, and is also adapted to engage the filling on the bobbin. The second head extends out of the first head, and in engaging the filling on the bobbin depresses the filling and causes the first mentioned-head, by its engagement with the filling, to be held in its inoperative position, but. when the filling on the bobbin is practically or substantially exhausted, the few layers of the filling remaining on the bobbin will not be depressed sufficiently to prevent the longitudi nally moving spindle from revolving,.and

.iu the direction of arrow cl,

through this motion to put into operation the mechanism which operates the weft replenishing mechanism, which may be of any ordinary construction.

My invention consists in certain novel features of construction of my improvements which may be adapted to be applied to and used on any well known weft replenishing loom having a magazine for bobbins or fill mg carriers, said magazine being either stationary or movable.

I have only shown in the drawings a detached portion of a weft replenishing mechanism of a 100111 of the class referred to, with my improvements applied thereto, sufiicient to enable those skilled in the art to understand the construction and operation thereof.

Referring to the drawings :Figure l is a plan view of a detached portion of the end of a loom, and a portion of a shuttle, with my improvements applied thereto. Fig. 2 corresponds to Fig. 1, but shows some of the parts in a dilferent position. Fig. 3 shows, on an enlarged scale, a central section through the footer, on

line

Fig. 5 corresponds to Fig. 3, but shows some parts in a different position. Fig. 6 shows the end of the fecler, looking in the direction of arrow 0, same figure. F 7 is a portion of the feeler spindle, detached, looking Fig. 5. Fig. 8 is the spindle head, looking in the direction of arrow '0, Fig. 7. Fig. 9 shows a modified construction of the spindle head. Fig. 10 shows the spindle head, looking in the direction of arrow f, Fig. 9.

In the and 2, l is a portion of the 100111 side or end frame, 2 is the breast beam, on which is mounted in this instance a plate or stand 3, having the rcarwardly extending arm. 3, with two stands l thereon for therotary .l'eeler, to be hereinafter described.

accompanying drawings, Figs. 1,'

5 is the shuttle, which carries a bobbin (5 having filling 7 thereon.

The mechanism which operates the Weft replenishing mechanism, shown and described in my U. S. Letters Patent, No. 933,492. dated September hereinafter described.

In the stands at on the arm 3 is in this 7, 1909, will be instance adjustably secured a bearing or support, shown in thls'instance 1n the shape of a tube 8; the oute 1: .end of the tube 8 is suitably covered and inclosed by a mp8, see Figs. 3 and '5, and in the other end is a sleeve or cylindrical part 9,.adapted to have asliding motion within-a hollow part of v the tube 8.- The sleeve '9 has an elongated slot or groove 9' therein, shown by dotted? lines in Figs. Band 5, into which extends the inner end of a set screw 10 which exlends through an opening in the tube 8. A rod or spindle 11 extends thIOUgli-lltliB central hole in the sleeved), and through the cap cover 8' on the tube 8. One end of the spindle 11 hasfastened thereon, by a set screw 12, the hub 13 of a hook lever 18. A helieally coiled expansion spring 14: enci'rcles'the spindle ll, and-bears at one end against the cap 8, and at its other end against the sleeve 9, and acts to move the sleeve 9 with the spindle 11, toward the shuttle. The spindle 11 has a in 11 thereon, which extends out from sai spindle and into a curved or cam-shaped slot 9". in the sleeve 9. The inner end of the spindle 11 is screw threaded, and has adjustably secured thereon, by a nut 15, a head 16, which in this instance has its outer end toothed, as shown at 16, see Fig. 7, and adapted to engage the filling. Within the.head 16 is a second head 18, whichis loosely held within the head 16by a pin 17 extending into an annular groove 18 in the head 18. The outer end of the head 18 bears against the ointed end 11 on the spindle 11. The

1ead'18 has in this instance its outer end toothed, as shown at 18", and extends slightly beyond the head 16, to engage the filling 7 on the bobbin 6 whenthe bobbin has a suflicient supply of filling thereon, as

' shown in Figs. 1 and 3.

On the forward movement of the lay to -ward the spindle 11, the engaging end of the.'head 18 will form a slight depression in the filling on the bobbin, and the filling will engage the toothed portion 16 on the head'lti, to prevent the spindle from re-' volving, and the pin 11' on the spindle 1 1, which extends into the curved or camshaped slot 9 in the sleeve 9, will move said 'sleeve, against-the action of the spindle 11,

see Fig. 3.

When the filling 7 0b the bobbin 6 is practically or substantially exhausted, as. shownact as a stop for the. operating lever shown 933,492. Said mechanism consists of a lever 20, to which the slide bar 19, having an elongated slot 19 therein, through which a guide pin 19 extends, is pivotally attached, and

which has a stud 21 thereon which extends into an elongated opening 3"inthe plate 3.

A hclically coiled contraction spring 22 is. attached at one end to th stud 21, and at its other end to a stud 23 for an angle lever 24:,

which lever is loosely mounted on said stud 23, and has one arm made yoke-shaped, with an open end slot 24 therein, to receive, the

end 25 on 'a vertically extending rocking lever 25,"havi-ng its hub 25 loosely mounted on the stud 26. The hub 25" has an extension 25 thereon carrying a pin 27, on

which is pivotally mounted the upper end 28 of a {rod orconnector to a. cam lever, not

shown, which is preferably operated by a cam, not shown, on the bottom shaft of the loom, not shown, to communicate a pivotal movement to the lever 24.

The anglelever 24 has a movement communicated to it, by the rock lever 25, at every other pick of the loom, said lever 24 has an elongated opening 24" therein, to re ceive a stud 29 on one end of a link 30; the other end of the link 30 is pivotally attached to a stud 31- on-the arm 20. 1

The stud 21 has secured thereto one end of a curve shaped arm 35; the other end of said arm 35 is connected with a pin 36 on one arm of an agle lever 37, the hub 37 bf. which. is pivotally mounted on a' stud 38 'on the loom side. The other arm of the an 1e lever 37 carries a stud 39, which is-pivotally 'connected to thelower end of a link or connector 40; the upper end of said link or connector 40, not shown, is connected with the transferrer mechanism of the magazine. 7

All of the last above mentioned parts are of the same construction and operation as, Shown in my said Letters Patent above re ferred to, and form no part of my present invention.

In Figs. 9 and 10 is shown a modified construction of the spindle head. 'In said figures, the pointed end 11 of the spindle engages the bobbin, and depresses the filling, an

when the bobbin has a'sufiicient supply 'of filling thereon. The needle points 20 are suitably secured to a conical shaped washer 21, by a ring 22. The washer 21 is adjustably fastened on the threaded end of the 5 spindle llby a' nut 15*. When the. filling on the bobbin ispractically or substantially exhausted the needle points are not engaged by,

the filling and the spindle is allowed to rotate. 1'30 a series of needle points enter the filling 2 0 It will be understood that' the details of construction of my improvements may be varied if desired.
