FEELER-MOTION non Looms.

Specification of Letters Patent. t t Dem 145-1920,

' Application filed October 26, 1918. Serial No. 259,740. I

To all whom it may concern Be it known that I, JAMES a citizen of the United States, and a resident of Lewiston, in the county of Androscoggin and State of Maine, have invented an Improvement in Feeler-Motions for Looms, of which-the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

The invention to be hereinafter described relates to looms and more particularly to feeler motions to effect a change in the operative condition of the loom when the filling reaches substantial exhaustion but prior to complete exhaustion.

In weaving certain kinds of fabrics using a plurality of shuttles much delay and loss of production occur when any one of the shuttles fails to lay a complete pick in the shed. In. such event, the loom must be stopped and turned back to find the pick as it is called, This is necessary because otherwise the pattern effectwould be destroyed and the resulting fabric be imperfeet. The difiiculty of turning back to find the pick becomes emphasized when, in addition to the figuring effect produced by two or more shuttles, the warps are also pattern controlled, as by a jacquard.

An important feature of the present invention, therefore, consistsin providing two feelers, one at each side of the loom, which act alternately to feel for and detect the condition of the filling in different shuttles, and upon detection of substantial exhaustion by either fceler set a train of mechanism in action to change the operative condition of the loom. The change in the operative condition of the loom may be effected by replenishment of filling or it may b b g.

the loom. In either case, however,the difiiculties and objectionable delays and loss of production due to finding the pick when only a partial shot of filling is laid in the Another important feature of the invention consists of two feelers, one at each side of the loom, cooperating with two shuttles, one feeler acting in conjunction with one of the shuttles at one side of the loom and the other feeler acting in conjunction with the other shuttle at the opposite side of the loom.

The above and other features of the inven H. BAnLow,

tion and novelcombinations of parts will be best made clear from the following description and accompanying drawings of a good practical form of the invention and its various novel characteristics.

In the drawin s: r a Figure 1 is a front view of a loom showng the present invention applied thereto,

p some of the parts being broken awayand Fig. 3; r Fig.6 is a section on line 66, Fig. 3; Flg. 7 is a perspective view showing the relation of parts whenone of the feelers detects substantial exhaustion of filling.

The invention will be hereinafter described in connection'with a loom for weaving cloth wherein two shuttles are employed, one carrying filling for weaving the ground and the other a filling for weaving a figure. .iiikewise, it'may be that twosets of warp may be employed, one set for the ground and the otherset forthe figure or pattern being controlled by a jacquard. Looms of this general type are employed for weaving figured cloth, such as counterpanes and the like, and being well understood by those skilled in the art no detailed description of the general loom parts and shedding mechanism is necessary. In looms of this type a two cell shuttle-box is employed at each end of the lay, one shuttle cooperating with the top cell at one'side of the loom and the bottom cell at the opposite side of the loom, and while the present invention is advantageously employed in connection with such type of loom, it may also be used with good results in other forms of looms, conbeing controlled by a usual heddle motion The loom frame may be of suitable char- I acter for supporting operating parts and as shown comprises the side frames 1 at the lower portion of which are mounted the lay swords 2 as usual for carrying at their up per portions the lay 3. The lay is given its usual reciprocating movements to beat up the filling by connection with the usual drive shaft or otherwise as conditions may dictate, and as the construction thus far described is well known and understood, further elucidation is unnecessary.

Mounted at each end of the lay is a shifting shuttle-box which, in the present instance of the invention, comprises two cells and suitable mechanism is employed for shiftin the shuttle boxes to brin the an- O b L propriate shuttle on the line of the race. In the present instance the lay 3 has mounted thereon at each end the shuttle box guides 4 and 5 between which is mounted the shifting shuttle box 6 having the two cells 7 and 8 as clearly indicated in Fig. Each of the shifting shuttle boxes6 is connected with a rod 9, the lower portion 10 of which passes through a guide 11 as indicated in Fig. 2 and at its lower end has a projection 12 connected by an adjustable link 13 with a shuttle box shifting lever 1 L pivotally mounted at 15 and suitably actuated at desired times by means of a cam 16 secured to the shaft 17, said cam acting upon a. roll 18 mounted on the shifting shuttle box lever ld as indicated in Fig. 2 The parts just described are the usual construction and while they present one good form of means for effecting the shifting movement of the shuttle boxes, it is to be understood, of course, that such shifting movement may be effected by ariously contrived means.

Pivotally mounted at 19, Figs. 1 and 2, is the usual picker stick 20, one at. each side of the loom, such picker sticks being actuated by suitable means through the lug straps 21 to pick the shuttle. The picker 22, Fig. 2, is mounted for sliding movement on the picker rod 23 as usual under the impulse of the picker stick, one of such being, of course, associated with each shuttle box. These parts may be of usual construction.

In a loom of the type under consideration wherein two shuttles are employed, one carrying a ground and the other a figuring filling thread, one of said shuttles cooperates with the top cell of the shuttle box at one side of the loom and with the lower cell of the shuttle box at the opposite side of the loom, the effect being that the shuttle carry ing the ground filling thread will, at one side of the loom, be received into the top cell of the shuttle box while the shuttle carrying the figuring filling thread will be received into the top cell of the shuttle box on the opposite side of the loom. The present invention, therefore, contemplates a feeler at each side I" the loom, one to detect the condition of the ground filling thread in the shuttle, and

the other to oetect the condition of the figuring filling thread in the shuttle, the construction being such that should either feeler detect substantial exhaustion of filling in the shuttle with which it cooperates, it will set in action a train of mechanism to change the operative condition ofthe loom and avoid laying of partial picks and the consequent necessity of turning the loom back to find the pick.

In the present instance of the invention the two feelers, one at each side of the loom, are mounted above their respective shuttle boxes and feel downwardly through the top of the shuttle, and while this construction is found to be advantageous inasmuch as it does away with the necessity for slotting the wall of the shuttle box and shuttle for the entrance of the feeler, it is to be understood that the invention is not restricted in this respect. In carrying this feature of the invention into effect in the present instance, a feeler support 24- is mounted at each end of the lay above each of the shifting shuttle boxes and mounted on the f eler supports 24 are the two

feelers

25 and 26 which, as the shuttle boxes are raised feel into the respective top cells of the boxes to detect the condition of the filling in the shuttles. The

feelers

25 and 26 may be variously contrived but in the present instance of th invention they are of the impinging and pene trating type, the general construction of such feelers being indicated in Figs. 3 and 6. Referring to said Figs. 3 and 6, the feelers comprise a feeler stand 27 appropriately secured to the respective feeler supports 24c one at each side of the loom. Mounted for reciprocating movement in the feeler stand 27 is the slide 28 the lower portion 29 of X ch constitutes an impinging member. E. tending through the slide 28 at its end portion is the penetrating feeler member 30 having an angular portion 31 adapted to bear against a finger 32 pivoted at 33 on the feeler slide 28. The finger 32 is normally held in its inoperative position by a plunger 3 1 normally under the influence of a spring 35, the construction being such that should a working supply of filling be present in a shuttle when the feeler performs its detecting function, the penetrating member 30 will sink into the filling and then the impinging member 29 will be engaged by the filling mass and the slide 28 will be lifted as the shifting shuttle box is raised to its upper position to bring the lower cell of the shuttle box in line with the race. If, however, the

filling should be substantially exhaustec when the feeler performs its detecting function as indicated in Fig. 6, the penetrating member 30 will engage the more dense mass of the filling carrier or bobbin 36 contained in the shuttle occupying the upper cell of the shuttle box and will be moved upwardly thereby to defiect the finger 32 or move it against the action of the spring plunger 3e into an operative position and upon further upward movement of the shuttle. box the finger 32 will act through a train of mecha nism to cause a change in the operative condition of the loom. In the'present instance of the inventionthis change in the operative condition of the loom is utilized to effect loom stoppage.

Pivotally mounted at 37gadjacent each of the feelers, Fig.3, is a controller 38 formed as a lever one end 39 of which is normally out of the path of the finger 32 of the feeler when the feeler performs'its detecting function and a working supply of filling is present in the shuttle, but when the filling has become substantially exhausted and before complete exhaustion, the finger 32 will engage the arm 39 of the controller and move it: to actuate a train of mechanism to effect the desired change in the loom operation.

Pivotally mounted at 40 and connected to each of the controllers or levers 38 is a pin or plunger 41 which extends through a block 42 secured to the feeler support 24.

Each of the feeler supports 24 is provided with a slot 43 extending longitudinally thereof and extending into each ofsaid slots is a pin or lug 44which, as the lay performs its reciprocating movements, is caused to slide back and forth in said slots and past the position of the pins 41. Each of the pins 44 is appropriately mountedupon a slide 45 which is guided in its reciprocating movements by bridge pieces 46 as more spective fingers or arms 49 in normal po-y sition, the construction being such that as the lay is reciprocated toward and from the front of the loom or the breast beam 47, the slides 45 will be reciprocated longitudinally of the feeler supports 24. If, however, either of the pins 4l is depressed into the path of either of the pins or lugs 44"on the slides 45, the reciprocating movement of one of the slides 45 will beinterrupted or retarded with the effect that as therla'y moves backward the rock-shaft 48 will be rocked. Advantage is taken of this rocking movement of either of the rock-shafts 48 to change the operative condition of the loom, as will more fully appear.

Extending from the breast beam 47 at one side of the loom, at the right in the illustrated form of the invention, there is a shipper bracket 52 having a slot 53in-wh1ch is movable the shipper 54. Thesh1pper-54 may be operatively connected with the source of power as, for instance, a belt shipper or I f the shipper 54 when the latter is in its holdslides 45.

' detached from its holding notch.

Pivotally mounted on the ship er stand 52 at one side of the loom at 56, *ig. 7 is a knock-off lever, 57 having a curved end portion 58 adapted to be engaged by a depending arm 59 extending from the rock shaft 48 at that side of the loom. The knock-off; lever 57 normally rests against ing notch, the construction being such that 8.5 should the rock-shaft 48 at that side of the loom be turned or rocked under the con ditions hereinbefore described, the finger 59 will ride along-the inclined end 58 of the knock-off lever 57 and detach the shipper lever from its holding notch and, perforce,

effect loom stoppage.

- Extending transversely of the loom adjacent the breast beam 47 is a slide 60 mounted for sliding movement in" a. support 61 adjacent 1 the shipper lever 54, as indicated in Fig. 1. The slide 60 adjacent the shipper lever 54 is provided with a notcheddetent 62"as indicated by dotted lines in Fig.7, 'said detent having an inclined portion 63 which, when moved to the left, Fig. 7, is adapted to engage and move the shipper lever 54 fromits holding notch. The slide 60 at the side of the loom opposite the shipper lever 54, as shown by Fig. 1, is provided with a lug 64 adapted to i be engaged by the finger 65 extending from.

the rock shaft 48, the construction being such that if the rock-shaft 48. be rocked owing to interruption in the sliding movement of the slide 45 at that side of the loom, the arm 65 will engage the lug 64 of the slide 60 and move it lengthwise to effect disengage ment of the shipper 54 from its holding notch thereby effecting loom stoppage.

" From the construction described it will be apparent that should either one of the feelers'at either side of the loom detect substantial exhaustion of filling in the shuttle with which it cooperates. and thereby arrest movement of the slide 45 associated vthere with, a change in loom operationwill result, such change in the present instance of the invention bringing the loom to rest.

It is desirable ina loom of the character 126 described that after the 100m has been stopped the attendant may be enabled to start the loom again from either side of the loom and to this end the slide 60 has connected thereto at the side of the'loom'op- 130 posite the shipper handle, a hand lever 66 pirotally mounted at 67 to a bracket extending from the breast beam 47 and jointed at (38 with the slide 60. The detent 62 at the opposite end of the slide (30 has an abrupt lug 69 between which and the inclined pon tion 63 of the detent the shipper 54: is embraced, the construction being such that should the hand lever 66 at the left hand side of the loom, Fig. 1, be moved clockwise, Fig. l, the shipper handle at will be drawn into its holding notch and there held to maintain the loom in operative condition. Likewise, at the right hand side of the loom as indicated in Fig. l, the shipper 5% may be directly manipulated by the attendant to start the loom.

While the above described construction forms a good practical embodiment of the present invention, various changes may be made within the true scope'thereof as applicant believes himself to be the first in this art to provide two feelers, one at each side of the loom, each to cooperate with one of a plurality of shuttles to effect a change in the operative condition of the loom when either feeler detects substantial exhaustion of filling in the shuttle with which it cooperates.
