To-all it may concern:

Be it known thatL JoHN' C. BRooKs, a citis zen-of-theUnited States, residing at Paterson,

in the county of Pas'saic and State of NewJer- .sey, have invented an Improvement in Looms, v of whichthe following des'cription, in eonnection with theaccomp'anying drawings, is a the drawings.

cially to means for detecting the occurrence of a float in the,warp.and"for immediately stopping the 100m upon theo ccurrence'of pick-outs, as they are termed. r In my present invention the stopping o the loom is accomplished by means of a feeler which cooperates with a feeler-jcontroller car 7 ried by the shuttle to knock ofirthe shipperlever whenever a float occurs, I

In the best form of my- 1I1Vent1Qn-n0W known to me the feelervis pivoted to the lay,

and the shuttle is provided with a recess or opening into and out ofwhi ch oneend of the feeler plays, said feeler being givenits'movement relative-to the shuttle by or through the 'movementof the lay. Carried bypthe' shuttle is'a feeler-controller which is normally held in its inoperative position out of the. path'of the feeler by means of a float-detecting lever.

Suitable automatically-operative means, such as springs, are employed tothrow the feelercontroller into its operative position, which is inthe patheof thefeele'r, whenever the float-detecting lever releases said fecler-controller by or through the occurrence of a float. As soon as the 'feeler-controller is thus thrown'xintg') its operative position across theopening in the shuttle said feelerbontrolleiv cooperates with the feeler upon the forward b'eatof the lay to knock-oil the shipper, and fthus stop the loom. ln the drawings, Figure 1 is a side View of a portion-of the 100m having-my improve ments applied thereto, the lay'and shuttle being shown in section to better illustrate my invention. Fig. 2 is a section of a shuttle having my improvements applied thereto on' Loom;

substantially the use Fig.3.- Fig, 3- is :1

itop plan view of Fig-. 2.

The breast-beam of, he loom 3, the shippcr-- shuttle is designated by S and may be of any suitable-or usual type,"said shuttle having at one end-an opening or recess 9, which comes .inalinement with'the opening 8 in the shuttle-box when said shuttle is properlyboxed.

' Mounted inasuitable recess in the side ot' the shuttle and arranged to: be moved back and forth across the mouth of the recess 9' is a feelerecontroller 10, which cooperates with the feeler upon the occurrence of a float to stop the loom. As herein illustrated, said *zt'eeler-controller comprises a sliding member mounted in a suitable recess 11 in the-wall of the shuttle, said feeler-controllerbein'g guided in any'suitable Way, as by means of thepins 12, carried by" the shuttle, which extend through the'slot 13 in said feeler-controllciz- Said, feeler controller is provided with a shoulder; 14, adapted to be engaged by the "nose 150i a float-detecting lever;16,,s'aid le-' ver being pivoted inthe'recess 11 of the shut- I :tleand having one end 17 thereof projecting above the shuttle-wall, as best seen in Fig. 2. w-The float-detecting lever is held in operative position, or that shown in Fig..-2,"in any suit able way, as by a spring 18.

Suitable automatically operative means,

i such asa spring 19, is employed to throw the feeler-controller into. its operative position whenever it isreleased, by the float-detecting lever, I." V} i Y i The parts are normallyin-the position shown in Fig. 2' that is, the 'feeler 4 controller; is withdrawn from acrossthe recess '9 and is held inits retracted or inoperative position by the floa't-detectir lever 16.

,Whenevera; float occurs in the warp and the. shuttle makes an overshot, the warpthreads will by their engagement with the end'l'? of the float-detectinglever depress said the shuttle-box.

end, and thus release the fecler-controller. Thereupon the spring 19 comes into play to throw said feeler-controller forward and over the opening 9 in the shuttle. W hen the feelercontroller is in this position, which is its'operative position, it cooperates with the feeler to stop the loom, as will be presently described.

Iivoted to the loom-frame is a hanger 20, which is suitably connected to one arm of the knock-ofi' lever 21. Said hanger 20 also carries a suitable buffer 22, which stands in the path of movement of the bunting end 23 of the feeler.

When the loom is running normally, the fceler-conlroller 10 is withdrawn from the opening 9 in the shuttle, as shown in Fig. 2, and as the shuttle is boxed it stops with said opening in alinement with the opening 8 in As the lay beats up and the feeler strikes the buffer 22 it is thrown from the full-line into the dotted-line position, the end 7 thereof being moved into the recess 9 in the shuttle. When, however, a float occurs, the feeler controller is released, as above described. and is'moved across the recess 9 by the action of the spring 19. When the lay makes the next forward movement and the feeler strikes the buffer 22, said feeler is prevented by its contact with the feelercontroller from swinging into the dotted-line position, and therefore becomes a rigid hunter, and as it strikes the buffer it forces the lever 20 back, and thereby knocks the shipper off,

thus stopping the loom.

The buffer 22 is preferably yieldingly mounted, and its operative face is inclined, as shown. so that when the feeler is held by the feeler-controller in its operative position it will strike the thicker portion of the buffer.

\Yhile my improvements can be applied to any type of loom and can be used in connection with any type of shuttle, I have herein illustrated an ordinary spindle-shuttle. 'ith suitable modifications, however, the invention can be applied to shuttles commonly used on looms in which the filling is automatically replenished when exhausted.

The particular form of knock-off device for the shipper-lever is not essential to my invention, and the arm 20 may be connected to any of the knock-off devices commonly employed in looms without in any way departing from my invention. It will be obvious, therefore, that many changes in the construction and arrangement of parts may be made without avoiding the invention.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a loom, a shuttle, loom-stopping mechanism including a feeler, and means carried by the shuttle and cooperating with said feeler to stop the loom upon the occurrence ofa float in the warp.

2. Ina loom, ashuttle,.loom-stopping mechanism including a feeler, a feeler-controller carried by the shuttle and cooperating with said feeler to stop the loom upon the occurrence of a float in the warp.

3. In a loom, ashuttle havingarecess, loomstopping mechanism comprising a feeler, means to move said feeler into and out of the recess in the shuttle by or through the movement of the lay, and means cooperating with the feeler to stop the loom upon the occurrence of a float in the warp.

I. In a loom, a shuttle having a recess, a feeler, means to move said feeler into said recess upon the forward movement of the lay, a feeler-controllcr, means to move the latter into its operative position across said recess and into the path of the feeler whenever a float occurs in the warp, and means cooperatin the warp, said feeler-controller when opoted to the lay, means to roclrsaid fecler' by or through the movement of the lay, a normally inoperative feeler-controller carried by the shuttle, and means to render said controller operative upon the occurrence of a float in the warp, said controller when operative cooperating with the feeler to stop the loom.

7. In a loom, a shuttle provided with a recess, a feeler pivoted to the lay, a feelcr-controller, a float-detecting lever to hold said feeler normally inoperative, automaticallyoperativc means to throw the feeler-controller into operative position when the latter is released, and means cooperating with said feeler to stop the .loom when the feeler-controller is in its operative position.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

I JOHN G. BROOKS.
