SPECIFICATION forming part of Letters Patent No. '789, i7'2, dated May 9, 1905,

Application filed February 18, 1905. Serial No, 246,231.

To all who/11, it may concern:

Be it known that we, EVERETT S. 001) and J ONAS Non'ruuor, citizens ol the United States, and residents of Hopedale, county of 'orcester, State oi? Massachusetts, have invented an lmprovement in Filling-Exhaustion lndicatiiig and Controlling Mechanism for Looms, of which the following description, in connection with the accompanying drawings, is a specilication, like characters on the drawings representing like parts.

This invention has for its object the prod uction of novel and accurately operating mechanism to positively control and effect a change in the operation of a loom when the filling in the running shuttle has become substantially exhausted or woven off to a prede termincd extent. The change in the operation of the loom may be the automatic stoppage thereof to enable the Weaver to provide the running shuttle with a fresh supply of filling, or it may be the actuation of mechanism to automatically e'l'l'ect replenishment of the running filling without stopping the loom. Replenishment of the running filling automatically may be elfected by mechanism of thefiNorthrop type, shown in United States PatentNo. 529,940 and others, wherein a fresh supply of filling is inserted automatically in a running shuttle of the automatically selfthreading class without stopping or varying the speed of the loom. As such looms are in extensive use, we have herein illustrated one practical embodiment of our invention in connection with a loom provided with automatic filling-replenishing mechanism of the Northrop type hereinbeiore referred to.

The filling-exhaustion-indicating mechanism in the present embodiment of our invention comprehends two movable members, one of which intermittingly impinges on and is moved by means within the shuttle until the running filling is exhausted to a predetermined extent, and an actuator operatively connected with such member mounted on and movable relatively to the other member into inoperative position by the intermitting movement of the first-named member. The member on which the actuator is mounted is 111m able by impingement on a vibrating part of the loom only when the predeterl'niued exhaustion of the filling permits, thereby causing the then relatively quiescent and operativcly-positioned actuator to effect the actuation of mechanism which controls the operation of the loom. Inasmuch as one of the members supports or carries the other member, we have hereinafter designated the former as the carrier, and the member supported thereby is termed the 'fceler, as it intermittingly impinges upon and feels the filling in the running shuttle to indicate the volume thereof or, in other words, its degree of exhaustion. Up to the point of predetermined exhaustion of the filling the 't'eeler acts on each feeling movement thereof to move the actuator relatively to the carrier on which it is mounted and renders the actuator inoperative. WVhen predetermined filling exhaustion is reached, however, the feeler becomes dead or inert with respect to both filling and actuator, and hence is ineffective to render the actuator inoperative, and the same remains quiescent with relation to the carrier. At such time the carrier is impinged on and moved by a vibrating part of the loom, such as the shuttle, and the relatively quiescent actuator is moved with the carrier as a unit to effect the actuation of the controlling mechanism for the loom. The construction is simple, direct, and positive in its action and so arranged that the change in the operation of the loom is impossible until the filling in the running shuttle is exhausted to the predetermined extent. Herein there is no pressure whatever on the filling carrier or bobbin at the instant of filling replenishment, for such operation is effected when the shuttle engages the carrier or a part fixedly mounted thereon, the feeler at such time being dead or inert and performing no work.

The various novel features of our invention will be fully described in the subjoined specification, and particularly pointed out in the following claims.

Figure 1 is a top or plan view of a portion of the left-hand side of a loom with one embodiment of our invention applied thereto, the running shuttle being in position for cooperation with the lilling-exhaustion-indicating mechanism on the forward beat of the lay. Fig. 2 is a left-hand side elevation of the mechanism shown in Fig. 1 with a portion of automatic filling-replenishing mechanism shown at the opposite side of the loom. Fig. 3 is a rear elevation of the transmitter intermediate the feeling devices and the replenishing mechanism to be described. Fig. L is an inner side elevation, enlarged, taken at the left of the line f a, Fig. 1, of the feeling devices and a portion of the transmitter. Fig. 5 is a much-enlarged longitudinal section on the line 5 5, Fig. 1, taken through the center of the carrier, the parts being in normal'position. 6 is a transverse section on the line 6 6, Fig. 5; and Fig. 7 is a top or plan view of the carrier and feeler, a portion of the actuator being broken off to show the part beneath it.

The filling-feeder F, Fig. 2, mounted on the breast-beam A and adapted to contain a supply of filling carriers or bobbins b, the transferrerf to transfer them one by one to the automatically self-threading shuttle S, and the controlling rock-shaft (Z to effect the re plenishment of filling may be and are all substantially as in the Northrop patent referred to, an upturned arm 4", fast on the rockshaft, having pivotally connected with it a rearwardly-extended latch (Z to at times cooperate with a vibrating actuator, shown as the weft-hammer 1V. lVhen the rear end of the latch is moved into the path of the head W, it enters a recess w therein, (see dotted lines, Fig. 2,) and the forward movement of the weft-hammer pushes the latch forward, acting through arm (Z to turn the rock-shaft (Z in the direction of arrow 200, Fig. 2, to effeet the operation of the replenishing mechanism in well-known manner. The actuator, latch, rock-shaft, and intervening connections constitute controlling means for the loom and herein operate to gox'ern the time of operation of the replenishing mechanism.

Novel filling-exhaustion-indicating mechanism elfects the actuation of the controlling means when and only when the lilling in the shuttle has become exhausted to a predetermined extent, so that it is impossible to eject a bobbin from the shuttle until the filling has been woven off to the desired extent, thus greatly reducing waste, and, on the other hand, when the predetermined exhaustion is attained a fresh supply of filling is with certainty provided, so that there will be no pick devoid or partly devoid of filling.

The shuttle S has an opening 1 in its side wall (see dotted lines, Fig. 1,) to register with the usual opening 1 (see 1) in the front wall 2 of the shuttle-box 3 when the shuttle is properly boxed therein.

The notched holding-plate 4 for the shipper S is depressed at its outer end at 5 to support a vertically-adjustable bracket 6, having an inclined top 7, on which is adjustably secured by screws 8 a stand 9. By inclining the bracket-top T the stand is so inclined that the feeler, to be referred to, moves in a path closely coincident with the path of the lay A as it swings back and forth, so that filling in the shuttle impinging on the feeler acts substantially directly along its path of movement, obviating any bending or twisting tendency and imparting greater accuracy to the operation of the apparatus. In Fig. 2 the shipper is omitted for the sake of clearness of illustration. The stand is conveniently made in two parts bolted together and chambered out at 10, Fig. 5, to receive a transverse and rectangular enlargement 11 on the carrier, which forms one member of the filling-exhaustionindicating mechanism. The carrier (see Figs. 5 and 7) is preferably made as a flat elongated plate 12 of metal, having at its rear end a lateral enlargement or head 13 and at its forward end the enlargement 11, beyond which there is a preferably cylindrical shank 1 1, freely slidable through an opening in the front end of the stand 9. The enlargement ll slides freely in the chamber and is guided by the sides and top thereof, and a spring 15, coiled i around the shank 1 1 between said enlargement and the front end of the stand, serves to move the carrier rearward into the position shown in Fig. 5, the rear end of the stand limiting such movement. Said end 16 has an opening 17, Fig. 6, to receive the body portion 12 of the carrier and slidably support it. Upturned parallel cars 18 on the rear end of the carrier adjacent its head are connected by a crosspiece 19, having a threaded hole 20 to receive the threaded shank of a hunter 21, adjustable in the cross'piece and held in adjusted position by a check-nut 22. The flat body 12 is centrally and longitudinally slotted at 23 from the head 13 to the enlargement 11, and adjacent the latter short parallel guideways or flanges 24 are formed on the sides of the slot. \Ve have herein shown an actuator movably mounted on the carrier, said actuator being made as an elongated arm 26, fulcrumed between the ears 18 on a horizontal pin 27, and having a short lug 25 depending below the fulcrum, the actuator 26 being extended forward above the carrier and prolonged to project above the top of the stand 9, as clearly shown in Fig. 5.

The third member of the filling-exhaustionindicating mechanism is the feeler, and herein it comprises a broadened head 28 and an elongated shank 29, the feeler being made of metal and light in weight. its head being recessed transversely on its under side at 30 to receive the head 13 of the carrier. The feeler-shank freely enters the slot 23 and at its forward end rests upon the guideways 24 within the opening 16, the shank passing under the crossbar 19 and between the cars 18, as shown. A very slight longitudinal sliding movement of the feeler upon the carrier is provided by making the forc-and-aft width of the recess 30 greater than the distance from front to rear of the carrier-head 13, as clearly shown in Fig. 5. We have provided a positive connection between the feeler and the actuator 26 by introducing the lower end of the lug 25 between transverse shoulders 31 on the feeler-shank, (see Fig. 5, and owing to the great difference in lever-arms, comparing the lug 25 and actuator 26, the slight forward movement of the feeler on the carrier is sufficient to elevate the tip of the actuator a considerable distance above the top of the stand 9. Consequently when the lay beats up and the shuttle is boxed in the shuttle-box 3 the feeler will enter the shuttle and impinge upon the filling, and the feeler will thereby be moved forward relatively to the carrier. The slight distance permitted by the clearance of the head 13 in the recess 30 before the continued forward movement of the lay will move feeler and, carrier in unison against the action of the spring 15. This initial filling induced and relative movement of the feeler acts through the lug 25 to inoperatively position the actuator 26 by swinging it upward in the construction herein illustrated, so that when the carrier begins to move forward with the feeler the actuator will be inoperative and will remain so during the forward stroke of feeler and carrier. On the return stroke, the lay swinging back, the spring 15 serves to return the carrier to the position shown in Fig. 5, and after the filling recedes from the feeler the weight of the actuator 26 returns it to normal position and through lug 25 sets the feeler in impinging position in readiness for the next feeling stroke. Until such time as the filling in the shuttle is exhausted to a predetermined extent the feeler and carrier will be moved outward intermittingly, first inoperatively positioning the actuator on each active stroke, the amplitude of filling-induced movement of the feeler and carrier gradually decreasing as the diameter of the yarn mass on the filling carrier or bobbin diminishes. As such amplitude of movement decreases the distance between the bunter 21 and a vibrating part of the loom, such asthe front side wall of the shuttle, also gradually decreases, so that when the desired or predetermined filling exhaustion is reached the hunter will impinge upon the shuttle. At that instant the diminution in the diameter of the yarn mass permits the feeler-head to extend so far into the shuttle that there can be no filling-induced movement of the feeler, the latter thus lying dead or inert on the carrier, and consequently the actuator will remain quiescent with relation to the carrier and in its operative position. Then the continued forward movement of the lay as it completes its stroke will move the carrier and actuator forward together as a unit, the inert feeler maintaining the position relative to the carrier shown in Figs. 5 and 7. The means for causing the forward movement of the operatively-positioned actuator to effect a change in the operation of the loom will now be described. It is to be observed, however, that while there is sufiicient filling in the shuttle to impart movement to the feeler by impingement thereon such movement will cause the actuator to be inoperatively positioned, so that no change in the operation of the loom can be effected until just the desired point of exhaustion of filling is reached. By means of the adjustment of the hunter 21 the quantity of filling remaining at such time is regulated to a nicety, and the indicating mechanism is also thereby adjusted for bobbin di ameter and width of shuttle.

The plate 4. is provided with an upturned car 32, which carries a fulcrum-stud 33, Figs. 1 and 3, substantially parallel to the path of movement of the reciprocating carrier 12 14C, and on said stud is fulcrumed a transmitter (shown as a lever 34 35) operatively connecting the latch (Z and the filling-feeling device. The free end of the arm 34 extends beneath the latch and normally sustains it in inoperative position, a lug 36 on said arm then resting on the top of the breast-beam. (See Fig. 3.) At the opposite or outer end of the transmitter the arm 35 is bent laterally and forms an upright car 37 (clearly shown in Fig. 1) adjacent a guide 38 on the stand 9, the ear having a cam-slot 39 therein. A controller for the transmitteris provided in positive and sliding connection therewith and so constructed that the movement of the transmitter from inoperative to operative position, or vice versa, is effected positively, the controller locking said transmitter in either position. The controller is shown best in Fig. if as an arm 4L0, fulcrumed on an upright stud il, carried by a bracket 12, secured to the ear 32, the studs 33 and 4:1 being substantially at right angles to each other. The free end of the controller passes through the cam-slot 39 and under the guide 38 across the top of the stand 9, the controller end or foot 13 extending into the operative path of movement of the actuator 26, the rear edge of the foot being shown as notched, as at 44, (see dotted lines, Fig. 5,) while the free end or tip of the actuator is beveled on both sides or brought to an edge, at 5. 1 f the parts are in the position shown in Fig. 4:, the controller being then in the low portion of the cam-slot 39, it will be manifest that movement of the controller to the left or toward the front of the loom will act through the cam-slot to depress the adjacent end of the transmitter and rock the latter on its fulcrum The arm 34 is thereby elevated, and the latch (Z is moved into position to be engaged by its actuator vin,

the wefthammer as hereinoefore referred to. Inasmuch as the peculiar connec tion between the controller and transmitter locks the latterin position, itwill be manifest that the transmitter will be unaffected by shock or jar and can only be operated or rocked through movement of the controller. Remembering that so long as there is sufficient filling in the shuttle the impingement of the feeler upon the filling will move the actuator into inoperative position with its sharpened tip 45 above the foot 4C3 of the controller, it will be clear that no movement of the latter can then be effected, and when the tip l5 passes beyond the notched edge of the foot it is impossible for the actuator to cooperate with and move the controller. \Vhen, however, the exhaustion of filling reaches the desired point, there will be no filling-induced movement of the feeler, and the actuator will remain operatively positioned, as shown in Fig. 5, when the bunter 21 impinges on the shuttle, and as the feeler-carrier is moved forward by the lay as it completes its forward beat the tip of the actuator engages the notched edge 4:4 of the controller and moves the latter forward as the stroke of the feeler-carrier is completed. The transmitter is thereby rocked on its fulcrum, and the operation of the controlling means for the loom will be effected. Should the controller jump forward away from the actuator or the bunter away from the shuttle after engagement therewith, as may some times happen, it would not be material, for the feeler is then inert and there is nothing to move the actuator relatively to the feelercarrier, and are engagement of actuator and controller will be effected when the former catches up with the latter. Ordinarily, however, the engagement of the sharp end or tip of the actuator with the notch 44L in the edge of the controller will be maintained when once effected until the actuator and controller have effected the operation of the transmitter. If the tip of the actuator passes above the top of the controller, no matter how slight the clearance, there will be no actuation of the controller, while, on the other hand, if the tip is ever so little below the sharp edge formed by the top of the foot 43 and the beveled upper side of the notch 44 then the controller will be actuated. A very certain operation is thus insured when called for and premature operation is completely eliminated.

A spring 46 is coiled around the stud a1 and fixed at one end, its other end being connected with the controller o, the spring being so wound that it acts normally to hold the controller in the low or rear end of the cam-slot 39, with the transmitter locked in inoperative 3 position.

The filling-exhaustion-indicating mechanism is manifestly adapted to control either a filling-replenishing mechanism or a loomstopping mechanism, either mechanism constituting means to control the operation of the loom, the filling-exhaustion indicating mechanism governing the operation of such controlling means.

Various changes or modifications in construction and arrangement may be made by those skilled in the art without departing from the spirit and scope of our invention, herein shown and described in one practical and efiicient form.
