EARL A. THISSELL, OF LOWELL, MASSACHUSETTS.

WEFT-REPLENISHING LOOIVI'.

SPECIFICATION forming part of Letters Patent No. 774,459, dated November 8, 1904.

Application filed November 17, 1903. Serial No. 181,520. (No model.)

To all whom, it may concern.-

Be it known that I, EARL A. THIssELL, a citizen of the United States, residing in Lowell, in the county of Middlesex and Commonwealth of Massachusetts, have invented a certain new and useful Improvement in Weft-Replenishing Looms, of which the following is a specification.

This invention relates to weft-replenishing looms in which the filling is renewed by substituting a full shuttle for an empty one, and comprises means whereby the binder is moved outward from the shuttle-box during the expulsion of the empty shuttle and the introduction of a full shuttle, thus preventing the stop movement of the dagger-rod or protector-rod and the friction of said binder on said shuttles. Heretofore the binder has been provided with a projection arranged and adapted to be struck by a shuttle which is being transferred from the .magazine to the shuttle-box to crowd the binder out of the path of said shuttle; but this projection has been found to wear the shuttle rapidly and to roughen its surface in such a manner as to cause the threads to be caught thereby and to be broken. Such a projection on the binder is shown in United States Patent No. 733,884, granted July 14, 1903, to me. I dispense with this projection and provide means operated by the transferring movement of the shuttle-changer to move the binder out of the path of a shuttle being transferred.

In the accompanying drawings, on two sheets, Figure 1 is an inner end elevation of the shuttle-transferring mechanism, the lower part of the magazine, the shuttle-binder, dagger-rod finger, and other parts, and a vertical section of lay-beam and dagger-rod; Fig. 2, a front elevation of the part shown in Fig. 1; Fig. 3. an inner end elevation of the shuttlechanger, its cam, and alever operated thereby on the line 3 3 in Fig. 2; Fig. 4, an inner end elevation of thelower part of the magazine, the shuttle-box and shuttle-changer provided with a cam, the binder and another form of the means which connect the binder and said cam; Fig. 5,21 front elevation of apart of thelay with the shuttle-changer, shuttle-box, and the protector-rod or dagger-rod; Fig. 6, an outer side elevation of a part of the sh Little-changing end of the loom, showing the shuttle-box, picker-stick, protector-rod or dagger-rod, with its finger and dagger, the knock-off lever, and in vertical section the breast-beam; Fig. 7, a plan of parts of the breast-beam, the notched and slotted plate, the protector-rod or dagger-rod and dagger, and in dotted lines the knock-off lever and in the horizontal section the belt-shipper.

The lay-beam 6,the picker-stick E, the binder J, the dagger-rod or protector-rod U, and the dagger-rod finger u are all of usual construction as used in looms for weaving plain cloth and ginghams. The protector-rod U is a rockshaft, supported on the lay-beam, and the finger u is rigidly secured to said rod and is normally pressed against the binderJ near the free end of said binder to crowd the binder toward the back of the shuttle-box by a spiral spring a, Fig. 5, which resists the rocking of the protector-rod. The protector-rod also carries a dagger 10 which projects forward and passes under the breastbeam a when the lay swings forward. l/Vhen a shuttle is in either shuttle-box during the forward swing of the lay, the free or front end of the dagger-rod is depressed sufiiciently to pass under the knockoff lever V, pivoted at e on the under side of the breast-beam a; but when during such forward movement there is no shuttle in either shuttle-box the dagger strikes the long arm of said knock-off lever and causes the short arm of said lever to press the belt-shipper W out of the notch 00 in the slotted and grooved plate X, whereupon said belt-shipperis caused by a spring (not shown) to swing outward in the slotw of said plate X and to shift the belt from the fast to the loose pulley in a wellknown manner. Obviously any contrivance which prevents the binder from swinging into the shuttle-box will prevent the above-described operation of the protector-rod. Vith these parts may be used any suitable magazine, movable shuttle transferring device, adapted to receive shuttles one at a time from said magazine and to place them on the lay. beam, and means operated by the movement of said transferring device to move the binder away from the shuttle-race and allow a shuttle to be placed on said race.

I have shown a magazine F, rotary shuttlechanger M, pawl-lever P turning on the shaft 1, on which said changer M rotates, and connected by a rod or link Q to a lever, (not shown.) as fully shown and described in said patent and in another patent, No. 73 L007, granted July 21, 1903. The construction of these parts is' not of the essence of my present invention, and it is sufiicient to say that upon the breaking or exhaustion of the filling or weft the changer M is caused to make a partial revolution upon the shaft I and to carry a shuttle which is beneath the magazine in the upper compartment of said changer or in contact with the wing of of said changer which, for the time being, is uppermost to the shuttlerace between the binder and the shaft 1, while the wing m which, at the beginning of said partial revolution forms the top of the shuttle-box, passes down behind the binder and pushes the next previously operative shuttle through an opening in the bottom of the shuttle-race. When the last-named wing passes below the binder,the binder,unless prevented,

will swing into the shuttle-box and allow the 5 dagger-rod to operate to stop the loom, be-

below the top of the binder. Even if the loom To prevent these occuror shuttle-compart- 3 movement of the dagger-rod or protector-rod. Each cam -surface in turn holds the binder away from the path of the shuttle until the shuttle-changer has completed its partial rotation, and said cam-surface terminates suddenly in a radial plane d, which allows the lower arm of the lever C to be moved suddenly in toward the center of the cam, which it will be caused to do by the usual daggerrod spring 12/.

In Fig. 4 I have shown a single two-armed lever C fulcrumed on a bracket (1 secured on the lay above the back of the shuttle-box port or entrance, one arm 0 of said lever reaching across the shuttle-box and bearing against the inner face of the free end of the binder and the other arm (J of said lever being held by a spring, represented as a spiral spring 0 against a cam D, which is not essentially unlike the cam D, and rotates with the shuttle-changer. Obviously the rotation of the cam D will operate to swing the binder away from the shuttle, as above described in the case of the cam D. In Fig. i the cam D and both arms of the lever C are represented as being between the magazine and the mid dle of the lay and do not, therefore, lie in the path of the shuttle being transferred, while i the arm 0 of said lever does not when in incause the new or full shuttle has not yet passed 1 Inents, each cam-surface acting upon such lecrank levers G C, fulcrumed upon stands 0 a,

secured upon the lay-beam band magazine F, respectively. The lever C has an arm a, which bears against the inner face of the binder J near the free end of the same, and another arm a, which extends over the shuttle-race and under the arm of the lever C, the lower end 0 of the other arm a of said last-named lever being suitably rounded to ride easily over the steps (I of the cam D. The cam D rotates with the shuttle-changer and acts upon the lever U just as soon as said changer begins to turn, pushing the binder away from the shuttle in the box to allow said shuttle to leave the box without friction on said binder and preventing the binder from getting in the path or rubbing on the side and lower corner of the entering shuttle and at the same time preventing the stop-motion operative position project in advance. of the back of the shuttle-box and. does not, there-- were not stopped the binder would be in the path of the new shuttle and prevent its reach- 5 fore, interfere with the traversing movement of the shuttle. In both cases the cam D D permits the shuttle-binder to swing into the shuttle-box when the shuttle-changer is not rotating.

I claim as my invention 1. The combination of a shuttle-changer, a binder and means independent of the shuttle operated by the transferring movement of said shuttle-changer to move said binder out of the path of a shuttle being transferred.

2. The combination of a shuttle-changer, binder, a protector-rod, controlled by said binder, and means independent of the shuttle operated by the transferring movement of said shuttle-changer, to move said binder out of the path of the shuttle being transferred and to prevent the operation of said protector-rod.

3. The combination of a shuttle-changer, a cam movable therewlth. a binder and means connecting said cam and said binder, to move said binder out of the path of a shuttle being transferred.

a. The combination of a lay, a rotary shuttle-changer, a cam, rotary with said shuttlechanger, a binder, and a lever carried by said lay and operated by said cam, to move said binder out of the path of a shuttle being transferred.

5. The combination of a lay, a rotary shuttle-changer, a cam, rotary with said shuttlechanger, a binder, a lever carried by said lay said binder out of contact With the shuttle and operated by said cam,to movesaid binder being transferred.
