To all whom it 'megl concern;

Be it known that I, I'IARRY W. SMrrn, a

resident of North Grafton, countyof Worces- .like numerals on the drawings representing i like parts. 10

This invention relates to looms having shifting shuttle-boxes and has forits object.

to provide such looms'with means for feeling the filling during the. backward movement.

of the lay and just prior to the picking of the active shuttle.

1 So far as I am aware,-all looms which have.

any filling-detecting mechanism comprising a feeler to feel for the filling are so constructed that the feeling action of tlie feeler takes place during the forward beat'of the lay, and it is usually necessary to make this feeling action occur during a small increment in the movement of the lay. The result 1s that the feeling motion; of the fe'eler is a quick one, which is liable .to injure delicate yarns. To. avoid this objection, I have 111 my co-pending application Ser-ial No. 293,911, Filed Dec. 30,1905,-descr1bed a loom a feelerwhich is adapted tofeel for havin ,the filling during the backward movement of tlielay so that more time may be given to theffeeling movement of the feele'r. The loom illustrated in said application is v a single box loom, and in mypresent' invention I have applied this type of feeler to a drop box loom having shifting shuttleboxes.

In accordance with my invention, I mount on the lay a feeler which moves with the lay, and I provide means for giving'said feeler its feeling ,movement during the backward movement ofthe lay, andujustafter the shuttle-boxes have shifted each shuttle-box is open at its side-to admit the feeler, and

' the shifting of the: shuttle-boxes brings. that 'box having the acting shuttle opposite the feeler, so that when the feeler is given .its feeling movement as the lay moves backwardly, said feeler enters theshuttle about to be thrown, and feels the'filling therein.

The feeler mechanism may beused either to stop the 100111 when the filling in any shuttle is practically exhausted or it may be used to control a filling-replenishing mecham' ism which will replenish the filling.

I- will now describione embodiment of vention, said my invention and then oint out the novel features thereof in the c aims.

In the drawings Figure 1 is a side view of a loom embodying my invention; Fig. 2 is a front view thereof Fig. 3 is a side view looking in the opposite direction from Fig. 1, and Fig. 4 is a section through a shuttle, such as'wil]. be used in this embodiment of my infigure showing the locker in operation.

3 designates the frame of the loom, 4 the lay, 5 the lay swords and 21 the cam-shaft.

and the drop boxes having the shuttles 8 therein. These parts may be of any suitable or usual construction and form nopart of my present invention. Since my invention does not relate to the mechanism for operating or controlling the drop box, I have not deemed it necessary to illustrate such mechanism'herein.

feeler mechanism is illustrated as operating to control a filling-replenishing mechanism, and for the sakeofillustration I have shown a filling-replenishing mechanism of the type shown in patent to Wyman & Crompton No. This filling-replenishing mechanism comprises a rotar hopper 6 containing a reverse supply of filing of different colors,

, which is situated-on the opposite side of the loom from the drop boxes, but-is connected to the mechanlsm for operating said boxes,

so that the hopper moves in unison with the boxes.

I have not deemed it necessary to illus} In this embodiment of my invention the 90. trate herein the entire mechanism-for rotatingthe hopper, as this forms no part of my present il'ivention' r The feeler'is located on the same side of the loom asthe shifting shuttle-boxes and each' shuttle-box is open on its front side to. admit the feeder during the feeling movement thereof. The feeler. is designated by 9 and it is herein shown as mounted on a slide ortcarriage "10 movably mounted on a'bracket 11 carried by the lay. The feeler is adapted to move'itoward-the shuttle to feel the fillingtherein, this feeling-movement occurring during the backward movement of the lay. Are stated above, any suitable mechanism may be employed for giving to the feeler its feeling movement provided such movement occurs during thebackward movement of the lay.

.he mechanism I have herein shown oomios prises a li ver 13 pivoted to a bracket 14 carried by th lay and pivotally connected at one end tohpe slide 10, and at the other end to one end a lever 15, which is pivoted to a bracket 17 ca 'ried by the lay. The lever 15 is connected by a link 19 withone end of a cam controlled lever 16 which is pivoted to a suitable bracket 18 carried by the loomits operative position.

frame. This lever 16 bears at one end against a cam 20 fast on the cam-shaft 21 and the lever is held against the cam by a suitable spring 22 which is secured at one end to said lever and at the other end to any suitable fixed support, which I have herein shown. Said fixed support has a collar 23 loosely mounted on the cam shaft 21. The cam 20 is provided with a low portion 210 which is so positioned that it comes under the end of the ever 16 just as the lay is moving backwardly subsequent to the pick which has driven the acting shuttle into oneof the shifting shuttle-boxes. The cam 20 normally holds the parts in the full line position, Fig. 1, that is, with the feeler withdrawn from the shuttle, but whenever the low portion 210 ofthe cam comes underneath the lever 16, the spring 22 operates through the levers above described to give the feeler its feeling movement toward the shuttle. Since this feeling movement of the feeler is caused entirely by the spring 22, it will be observed that it is a yielding motion rather than a positive one. I

The stop motion for the loom or the fillingreplenishing mechanism, whichever is to be controlled by the feeler, is, in this embodiment of my invention, actuated by or set in motion by a hunter 26 carried by the lay and controlled as to its position by the feeler. Normally the hunter occu ies the inoperative position shown in full incs, Fig. 2, but when the feeler detects the practical exhaustion of the filling, said bunter is thrown into The hunter is herein shown as being pivoted to the lay as at 32 and as being provided. with a tail 3]. to which is ivotally connected a connector 30 slidablg mounted in bearings 300 carried. by the lay. I This connector has at one end a head 29 adapted to engage one end of a controller 28 pivotally mounted on the fccler J as at 280. The other end of the controller is provided with a head 33 having an inclined surface 330 which cooperates with. an inclined surface 331 formed on one wall of the hole 332 on the side of the shuttle, through which the feeler 9 enters-to feel the filling 3335. The head 33 is preferably adj ustably mounted in the controller, and so positioned that the inclined surface thereof will not strike the inclined surface 331 of the shuttle, until the filling is substantially exhausted from the shuttle. With this arrangement of parts, it will be observed that so long as there is any "quantity of filling in the shuttle,

'the' hunter the inclined surface 330 of the head of the controller will not engage the corresponding inclined surface of the shuttle during the feeling movement of the fcclcr, and therefore the controller will normally retain the position shown in Fig. 4, in which position it is engaged by the connector. '\\h ncvcr the filling is substantially exlnmstcd. .howcvcr, the fceler will, during its feeling nmvcmcnt enter the shuttle to an extent sullicicnt to bring the head 33 against the inclined wall of the shuttle, thereby tilting the other end, and disconnecting it from thehcad 2.) of the connector. \Vhcn the connector is thus released, it will be moved to the right, Fig. 2, through mechanism which will be described, thus throwing the hunter into operative position.

The means for shifting the connector after it is released, comprises a lever 38 ivotcd to one of the lay swords as at 39, and carrying a pin 42 which occupies a slot ill of the connector, a spring -11 connecting the connector and said lever, and a cam 35 on the ram shaft 21 for oscillating said lever. 'lhis cam 35 is shown as engaging one cnd of a lever 36 pivoted to the floor or to the frame of the loom as at 37 and also having a pivotal connection with the lever 38. Each rotation of the cam shaft will cause the lever 38 to oscillate, but so long as the head of the connector engages the controller 28 such oscillation merely results in stretching the spring 41. As soon as the controller is released from the connector, however, as above dcscribed, said connector is free to move to the right, Fig. 2, and such movement will occur when the lever 38 is turned by the cam 35, thespring 41 serving as the connection between the lever 38 and the connector to cause the latter to move with the lover. The lever 36- is normally held against the cam 35 by means of a spring 390.

The type of fiHing-replenishing mechanism herein il ustratcd is tiat which contains a reserve supply of bobbins adapted to he inscrtcd into a shuttle. These bobbins are thus transferred from the magazine 6 to the shuttle at the proper time by a transfcrrcr 24- to which is pivoted a dagger 25. the hunter 26 is in its operative position, as is the case when the connector is in engagement with the controller, said hunter 25 does not engage the dagger upon the forward movement of the lay, and therefore the filling' replenishing mechanism does not operate. As soon, however, as the lilling in any shuttle is substantially exhausted, and for this reason the controller releases the connector,

tive position; in which position it strikes the dagger as the lay beats u thus causing a fresh bobbin to be su )plic' to the shuttle in place of the exhausted bobbin. It would-be possible, however, to use my mechanism for 130 When 26 will be thrown into its opera- 1 fee er occurs during the backward movement of the lay just after the shuttle boxes have been shifted and just prior to the picking of the shuttle. The feeler therefore 'always feels for the filling in the shuttle which is about to be thrown, and if the filling in said shuttle is practically exhausted, the fillingreplenishing mechanism is set in operation to re lenish such exhausted filling when the shutt e reaches the o osite side of the lay. By erforrning the filling o eration during the backward movement of t e lay, it is possible to give more time to it so that the feeler may have a softer and more delicate touch and be less liable to injure the filling than if the movement of the feeler had to be a quick one, as is the casewhen the feeling is accomplished on the forward movement ofthelay- Y The mechanism herein illustrated-is only one Way of carrying out the desired results,

and therefore I do not wish to be limited to the exact. construction shown.

Having fully described my invention, what I claim as new and desire to secure by Let-;
