FILLING-REPLENISHING LOOM SPECIFICATION forming part of Letters Patent No. 759,854, dated May 17, 1904.
Application tiled January 25, 1904. Serial No. 190,422. (No model.)
Be it known that I, ARTHUR E. BENSON, a citizen of the United States, and a resident of Magnolia, county of Pike, State of Mississippi, have invented an Improvement in Automatic Filling-Replcnishing Looms, of which the following description, in connection with the accompanyingdrawings, is a speciiication, like characters on the drawings representing' like parts.
This invention relates more particularly to automatic lilling-replenishing looms of the Northrop type, wherein the running shuttle .is provided with a fresh supply of filling, as shown in United States Patent No. 529,940 and others. The feeder or hopper which contains the reserve supply of filling-carriers prior to transfer to the shuttle is mounted at one side of the loom, and lilling replenishment is effected when the shuttle is boxed at the adjacent end of the lay. Should the replenishing mechanism be operated when the shuttle is in the opposite box, the transferred filling-carrier is inserted in the empty shuttlebox, and if it does not pass through the open bottom will, of course, cause damage when the shuttle on the next pick is thrown into the box. Even if the filling-carrier passes through the bottom of the box it may fall into some of the operating' parts of the loom and cause damage.l Manifestly, then, it is highly desirable to prevent operation of the filling-replenishing mechanism when the shuttle is in the wrong box, entirely aside from unnecessary diminution of the supply of filling sustained in the filling-feeder.
My present invention has for its object the production of means which will prevent the operation of the replenishing mechanism when the shuttle is in the wrong shuttle-box.
Sometimes after a loom has stopped the weaver' in starting up the loom pushes the shuttle into the wrong box, and as the filling may be slack or on account of carelessness of the weaver, the fork will not be operated and a filling-carrier is transferred when the transferring shuttle-box is empty.
My present invention is constructed and a1'- ranged to prevent such transfer, and it is very desirable on a loom of the automatic replenishing type equipped with two filling detectors or forks, as will be fully explained hereinafter.
In double-fork looms means have been provided to arrest the take-up when either fork detects filling failure and to `cause filling replenishment primarily throug'h the fork farthest from the filling-feeder. A rock-shaft is arranged to be turned by detecting' action of either fork, but it is turned far enough to cause filling replenishment and arrest take-up by only one fork. The other fork turns the rock-shaft only enough to arrest take-up, and t-o effect such operation there is lost motion between the slide of such fork and the rockshaft, or the corresponding weft-hammer is given a shorter stroke. In either case careful adjustment must be made, and if the two weft-hammers have different strokes their cams must be different. y
By the construction to be hereinafter described I obviate the use of lost-motion connections and the requisiteadjustment thereof, and I am enabled to use like cams and coperating parts for both the forks, simplifying construction and making' the `operation more positive and direct.
The various novel features of my invention will be fully described in the subjoined speciiication and particularly pointed out in the following' claims.
Figure l is a transverse sectional view of a portion of a loom, taken through the fillingfeeder and the adjacent shuttle-box with one embodiment of my invention applied thereto. Fig.` Qis a top or plan View of the replenishing shuttle-box with the shuttle therein, showing the novel controlling means for the lilling-replenishing mechanism in operative condition. 3 is a front elevation thereof. Fig. 4: is a plan View showing the shuttle-box empty and the controlling means positioned to prevent filling replenishment; and Fig. 5 is a plan View, on a much smaller scale, of the two filling-detectors and their connections with the rock-shaft, forming a part of the nected with the transferrer and held normally in the position shown in Fig. l by connections between said dog and the controlling rock-shaft d, said connections including an arm (Z2 and a yoke Y, may be and are of usual construction and operate in a manner well known to those familial' with the Northrop type of automatic filling-replenishing loom. In such loom when filling replenishing is called for the controlling rock-shaft d is turned .in the direction of the arrow 200, Fig'. l, to thereby permit the movement of the dog m15 into the path of a bunter on the lay, such bunter having been heretofore rigidly secured to the lay. Then the bunter and dog cooperate, as the lay beats up, the transferrerf removes or transfers a filling-carrier from the feeder to the shuttle S, Figs. l and 2, which shuttle is then in the replenishing shuttle-box BX-viz., that box which is at the end of the lay adjacent the feeder F. Filling replenishment is effected by or through the cooperation of two memberswsuch, for instance, as the dog' and the bunter hereinbefore referred tobut I have so arranged the apparatus that even though one of said members may be moved into operative position the other of said members will not be enabled to cooperate therewith unless the shuttle is in the replenishing shuttle-box.
Referring' to Figs. l to 4, inclusive, the inner end of the binder Blo of the replenishing shuttle-box is adapted to cooperate witha cam 1, secured to or forming part of an upturned arm 2 of a lever 3, fulcrumed beneath the lay at 4, the upturned end 2 rising behind the lay. The lever 3 extends forward below the lay near the mouth of the shuttle-box, as shown in Figs. 2 and 4, and its forward end is provided with a longitudinal slot 5, which is entered by a depending pin or stud 6 on the body portion 7 of the bunter 8. rIhe body portion 7 is mounted slidably upon the front of the lay and is held in place thereon by headed screw or other fastenings 9, (see Fig. 3,).extended through horizontal slots l0 in the body. By rocking' the lever3 from the position shown in Fig. 4 to that shown in Fig. 2 the bunter will be moved from inoperative to operative position.
In Fig. 4 the rear end of the dog m15 is shown, and it will be seen that the path of movement of the bunter is at one side of said dog, whereas when the bunter is moved into operative position, as shown in Fig. 2, it will cooperate with the dog' m15 on the forward beat of the lay and effect filling replenishment in a well-known manner. A spring' ll is secured at one end to a pin 12 on the lay, and its other endis attached to the bunter-body to move the latter to the left, Viewing Fig'. 3, when permitted so to do.
Then the replenishing-box B is empty, the binder B10 assumes the position shown therein, and the spring l1 is then free to move the bunter to inoperative position, the cam l assuming the position shown. Then the shuttle Venters such replenishing-box, however, the
binder is thrown outward, and its free end engages and wipes over the cam l, and thereby rocks the lever 3 into the position shown in Figs. 2 and 3, moving the bunter against the action of the spring into operative position, such position being maintained, of course, while the shuttle is in the box. It will be manifest, therefore, that unless the shuttle is properly positioned in the replenishing-box, and by such term is meant so far in the box that the bunter will have been moved into operative position, filling' replenishment cannot be effected, even if the other controlling member-viz., the dog M15-is in its operative position. If, therefore, the weaver in starting up the loom should push the shuttle into the wrong box and the usual filling' detector or fork should fail to tilt owing to slackness of the filling or absence, according' to the box in which the shuttle was inserted, the subsequent movement of the lay and the filling-detector could not cause the replenishing mechanism to be operated when the shuttle was in the non-replenishing box.
My invention is of particular value in looms wherein two filling-detectors are provided `to detect filling failure on alternate picks, and I have so constructed the mechanism herein that the connection between each detector and the controlling rock-shaft al is positive in its action when absence of filling is detected, and I am also enabled to obviate the use of any lost motion or variation in the shape of the weftliammer cam for one of the detector-slides.
Referring to Fig. 5, I have shown two filling detectors'or forks f and g, respectively, pivotally mounted on their slides f X gx, the outer ends of the slides engaging, respectively, upturned arms Z5 (Zw, fast on the rock-shaft d. Ieft-hammers M N are arranged to cooperate with the tails of the forks f and g when upon absence of filling either of the forks is not tilted to move the slide outward, and thereby turn the rock-shaft CZ in the direction of the arrow 200, Fig. l. The weft-hammers are given the same stroke, so that the two cams are interchangeable, and as the hammers have the same stroke it is manifest that the forkslides will have the same stroke, and consequently whichever fork by detection of filling failure causes turning of the rock-shaft CZ' the angle through which the rock-shaft is turned will be the same. This rock-shaft can readily be arranged to arrest the operation of any suitable take-up instrumentality by means of IOO IIO
an arm (ZM, Fig. 5, adapted to govern the operation of the take-up instrumentality, as, 'for instance, in United States Patent No. 727,014.
Ii the iilling iails as the shuttle is moving to the box B, the detector f will usually detect sueh failure, and the shaft el will be turned to cause the dog m15 to be set or operatively positioned, and on the next pick when the shuttle enters the replenishingsbox B the bunter 8 will be moved into operative position, as has been described, and iilling replenishment will be eiiected.
Should the filling fail on the shot of the shuttle 'from left to right, such failure will be detected by the Jfork g, and the rock-shaft (Z will be turned, as before, to cause the operative positioning ot' the dog/m.15 on the next pick; but on that next pick the shuttle will have been thrown from the box BX, so that notwithstanding the fact that the dog is in its operative position the iilling replenishing mechanism will not be operated, i'or the reason that the bunter 8 will be in its inoperative position. No thin place in the clothwill be made, however, because the turning of the rocl -shai`t by detecting' action of either detector will cause the arrest of the take-up instrumentality.
My invention is not restricted to the precise construction and arrangement shown, as various changes or modifications may be made by those skilled in the art without departing-'from the spirit and scope of my invention.
Having fully described my invention, what I claim as new, and. desire to secure by Letters Patent, is-
l. In a loom provided with filling-rel'llenishing mechanism, a lay, means to control the time or' operation ci' said mechanism, including an actuating member, movably mounted on the lay, and a device operative independently of the quantity oi' iilling in the shuttle to positively move said member into operative position by the shuttle when properly boxed for filling replenishment.
