SPECIFICATION formingpart of Letters Patent No. 726,574; dated April 28, 1903.

Application filed February 5, 1903.

T to whom it may concern:

Be it known that I, CHARLES F. Home, a

citizen of the United States, and a resident of Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Automatic Filling-Replenishing Looms, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates more particularly to looms provided with mechanism for automatically replenishing. the filling at the proper timeas, for instance, upon a predetermined exhaustion of the filling in the running shuttle or upon the failure of such filling.- A loom of this character to which my invention is applicable forms the subject-matter of United States Patent No. 529,940, dated November 27, 1894. In such looms it sometimes happens that a change of filling is called for at the same time that the shipper is released by or through the operation of the warp stop-c tion or the protector mechanism-2'. 2., upon the occurrence of a warp or a shuttle fault. When this occurs, the loom is slowing down, and the momentum of. the-lay is not always sufficient to complete the filling replenishment by driving the filling-carrier or bobbin into proper engagement withithe holding device therefor in the'shuttle. On starting up the loom again it is possible for the weaver to put everything in normal position, so that the loom will start with the filling-carrier loose in the shuttle, and hence liable to be thrown out, thereby causing damage of various kinds. So, too, when the loomis equipped with an antibang". device and the loom knocks oif with the shuttle in the shed a filling-carrier is certain to be thrown out of the hopper or filling-feeder by or through the action of the filling-fork if the loom turns over a sufiicient number of times. This of course makes one more. filling-carrier to'be put into the hopper by the weaver, audit may also cause trouble by having the fillingcarrier which is thrown fromthe hopper catch in the picker-slot or in the shuttle-box to be struck later by the shuttle.

In my present invention I have provided means to prevent the operation of the filling- Serial No. 141,946. (No model.)

replenishing mechanism if the shipper has been thrown off or released from its running position.

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

Figure 1 is atop or plan view of a portion of a loom at the shipper side thereof with one embodiment of my invention applied thereto. Fig. 2 is a left-hand side elevation of the apparatus shown in Fig. 1, a portion of the hopper of the replenishing mechanism being shown, the knock-off lever for the shipper being cut off on the line 2 2, Fig. 1. Fig. 3 is a right-hand side elevation of the dog, to be referred to, shown in Figs. 1 and 2, and Fig. 4 is a perspective detail of the dog to more clearly illustrate its construction.

Referring to Figs. 1 and 2, the breast-beam A", the notched holding-plate N for the shipper S, the controlling or operating rock-shaft d, by or through which the time of operation of the replenishing mechanism is governed, thestand b the filling detector or fork 12 and its slide bi, longitudinally movable in the stand by or through the wefthammer W, Fig.

1, may be and are all substantially as in said Patent No. 529,940, the stand a supporting the hopper or filling-feeder.

In Fig. 2 I have shown a frog F, mounted on the loom side A, the frog having a projectionf to engage the lower end of a knockoff leverf when the frog is moved forward byor through theoperation of protector mechanism of usual character. This protector knock-oif1everf as it may be termed, is fulcrumed at f on the loom side, its upper end being bent atf in front of the shipper, 0 so that when the lever is rocked in the direction of arrow 15 the shipper will be released from its holding-notch to eifect the stoppage of the loom in well-known manner. A second knock-off lever 7c is fulcrumed atJc on the breast-beam adjacent the holding-plate N, the outer end of said lever extending in front of the shipper, asshown in Fig. 1, the inner end of the lever having an enlargement k' thereon in front of a latch 01 on the filling-fork slide b. This latch operates upon two successive outward movements of the festly permitting the spring to act.

slide,substantially as provided for in United States Patent No. 529,943, to engage the enlargement 7c and move the lever to release the shipper and stop the loom with a fillingcarrier in the shuttle. A link 70 is pivotally connected at its front end with the knock-off lever 70, and at its rear end it is connected with the upturned end 70 of a lever 70 fulorumed at 7.5 on the loom side, (see Fig. 2,) a spring 8X acting upon said lever to normally keep the outer end of the knock-off lever 70 pressed against the shipper. When the ship per is released by the. protector knock-off lever f, the spring acts through link k to swing the lever 79 on its fulcrum in the direction of arrow 20, Fig. 1, for a purpose to be described, the release of the shipper mani- The slide b has an overhanging part b, terminating in a transverse shoulder 5 and a forward eX- tension 7) on a lower plane, the extension engaging a spring 5 Fig. 2, mounted on the loom-frame, the spring moving the slide rearwardly after it has been moved outward by or through detection of filling failure. An upturned arm d fast on the rock-shaft d, has its, upper end turned over at (1 above the extension I), and a stop-lug d is formed on the .outer face of the arm. The latter has fulcrumed upon it on a lateral pin d a peculiarly-shaped dog e, said dog being broadened on one side to form an overhanging shoulder e (see Figs. 3 and 4,) the rear edge of the shoulder presenting a face a, while the rear edge of the dog presents a beveled face e A rearwardly-projecting tail 6 on the dog extends from the shoulder over and normally rests upon the part b of the forkslide, and the enlargement k under normal conditions occupies the position shown in Fig. 2 beneath the part b and back of and adjacent the face 6 of the dog, while the shoulder 12 is behind and adjacent the face 6'. If the slide 17 is moved outward, as upon detection of filling failure, the shoulder b immediately engages the face a of the dog, moves the latter outward, and thereby swings the arm (1 out to turn the rock-shaft d far enough to effect the operation of the replenishing mechanism. If the protector mechanism operates, moving the frog F forward, the knock-off leverf will be turned to release the shipper from its holding-notch, and the spring s then moves the enlargement 70 forward to engage the inclined face 6 of the dog. This acts to swing the dog up on its fulcrum d into dotted-line position, Fig. 3, and thereby the shoulder e and its face 6 is lifted above the part b so that should the slide be moved outward the shoulder 6 could not engage the face e and the dog would not be moved. So long as the shipper is thrown off or in stopping position the outward movement of the slide b cannot act upon the dog and the replenishing mechanism cannot operate, even though the shuttle may have stopped in the shed, and the fork detects ahsence of filling, for the enlargement is keeps the dog in inoperative position. Such outward movement of the slide, however, will cause the shoulder b to engage the inturned end d of arm (1 and thereby turn the rockshaft d far enough to arrest take-up. substantially as provided for in United States Patent No. 711,736, dated October 21, 1902. A stop-lug e on the dog engages the lug d when the dog is thus rocked or tilted to prevent undue movement of the dog. If the slide 1)" is given a plurality of successive outward movementsas, for instance, if the first change offilling fails to properly thread in the shuttle-then the latch 61 drops behind the enlargement 7c and the knock-off lever k is turned to release the shipper on the next ou ward movement of the slide. At such time, however, the shoulder b of the slide will engage the dog before the latter can be rendered inoperative by or through the enlargement 7c, and as a result the second movement of the slide puts a filling-carrier in the shuttle substantially simultaneously with the release of the shipper. The lever 70 is arranged to operate when a warp failure occursas, for instance, in United States Patent No. 623,174'-and when the upper end of the lever is swung forward the link R will swing the knock-off lever 70, and thereby release the shipper. At such time the enlargement 70 will act as before described to render the dog 6 inoperative, so that the operation of the replenishing mechanism cannot be effected, even though the slide 11 is moved outward. It will be manifest, therefore, that whenever the shipper is released, Whether by the action of the protector mechanism or upon the occurrence of a warp failure, the replenishing mechanism will be rendered inoperative while the shipper is in stopping position. Even if the shipper is released by the Weaver the said mechanism cannot operate, for the part will, through the spring 3*, render the dog 6 inoperative or irresponsive to an outward movement of the fork-slide, as before described.

When the shipper is moved to running position, it engages the beveled end k of the knock-off lever 70, Fig. 1, and restores the latter to the position shown in Figs. 1 and 2, and thereby the enlargement it is withdrawn from the dog, permitting the latter to return to normal position. The spring s is merely strong enough to cause the knock-off lever 75 to follow the shipper when released from its holding-notch.

The failure of the shuttle to be properly positioned in the shuttle-box causes the operation of the protector mechanism and for the purposes of this invention is termed a shuttle fault, while failure or breakage of the warp is termed a warp fault.

The shipper is released from its holdingnotch by or through the knock-off lever 70, whether the warp or filling fails, as has been pointed out, while the protector mechanism acts upon the occurrence of a shuttlefault teams to release the shipper through the knock-off lever f The controlling rock-shaft d and the dog 6 carried thereby form part of the means for controlling the time of operation of the filling-replenishing mechanism, and the dog is rendered inoperative through the instrumentality of the enlargement 7r upon the occurrence of a fault in the warp or improper positioning of the shuttle, the shipper when released permitting the enlargement to be operatively moved at such time by another agency.

The member which throws the power on or off from the loom, shown herein as a shipper, constitutes a device to govern the operation of the loom, such device moving into position to stop the loom when released from the notch in the usual holding-plate, the return of the governing device to the notch effecting the starting of the loom.

My invention is not restricted to the precise construction herein shown and described, as the same maybe modified or rearranged in various particulars 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-

1. In a loom, a device to govern its operation, automatic filling-replenishing mechanism, and means actuated automatically and independently of said device to prevent the operation of the replenishing mechanism, when said device is in position to effect stoppage of the loom.

2. In a loom, a device to govern its operation, automatic filling-replenishing mechanism, means to prevent the operation thereof, maintained inactive by the governing device when the latter is in running position, and an actuator for said means, independent of the governing device, the actuator causing said means to operate when the governing device moves to position to effect stoppage of the loom.

' 3. In a loom, a device to govern its operation, automatic filling-replenishing mechanism, means to prevent the operation thereof when said governing device is in position to effect the stoppage of the loom, and an actuator operative by or through the occurrence of a warp orshuttle fault to render said means operative.

4. In aloom, a shipper, automatic fillingreplenishing mechanism, means to prevent the operation thereof, said means being maintained inoperative by the shipper-when in running position, and an actuator independent of the shipper to render said means operative upon movement of the shipper to stopping position.

5. In a loom, a shipper, automatic fillingreplenishing mechanism, normally inactive means to prevent the operation thereof, and an instrumentality independent of the shipper and operative by or through the occurrence of an abnormal condition in the warp or shuttle to render said means active to prevent operation of the replenishing mechanism when the shipper is in stopping position.

6. In a loom, a shipper, automatic fillingreplenishing mechanism, means, maintained inactive by the shipper when in running position, to prevent the operation of the replenishing mechanism, means to effect the release of the shipper by or through the occurrence of a warp or shuttle fault, and an instrumentality operative upon the occurrence of such fault to render said means active to prevent operation of the replenishing mechanism when the shipper is in stopping position.

'7. In a loom, filling-replenishing mechanism, and means to control the time of operation thereof, including aeontrolling-shaft and a pivotally-mounted dog carried thereby, a filling-fork, and a slide adapted to engage the dog and rock said shaft upon detection of filling failure, combined with a shipper, means to release it, and a device operative automatically upon release of the shipper to move the dog out of the path of the slide and maintain it in such position while the shipper is in stopping position.

8. In a loom, filling-replenishing mechanism, and means to control the time of operation thereof, includinga controlling-shaft and a normally operative dog carried thereby, combined with a shipper, means to release it upon the occurrence ofa warp or shuttle fault, and a device operated independently of the shipper upon release thereof to cooperate with and render the dog inoperative while the shipper is in stopping position, to thereby prevent the operation of the replenishingmechanism at such time.

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