WEFT-REPLENISHING MiECHAN'lSM FOR LOOMS.

SPECIFICATION formingpart of Reissued Letters Patent No.12,370, dated July 11, 1905. Original No. 786,240, dated March 28, 1905. Application lfor reissue filed April l2, 1905. Serial No. 255,256.

T all whom, it may condena.'

Be itknown that LEDwARD D. THAYER, acitizen of the United States, residing at `Worces ter, in the county of Worcester and State of Massachusetts,have invented an Improvement in Weft-Replenishing Mechanism for Looms, of which the following description, in connection with the accompanying drawings, is a specificationlike letters on the drawings rep- IO resenting like parts.

In looms having a filling-fork it is customary to supply-filling to the raceway of the lay without stopping the loom. So, also, it is customary to employ a so-called feeler coacting with the filling in a running shuttle to cause the filling-supplying mechanism to act and supply fresh filling prior to total exhaustion of the filling from the running shuttle, and with looms of this class a weft-fork has been 2O used solely for stopping the loom when the filling breaks. Provision for supplying filling prior to total exhaustion and for stopping the loom when the filling breaks is essential in a loom for Weaving perfect cloth.

The incorporation in a loom of means for feeling through the shuttle onto the mass of filling therein to start into operation at the proper time the means to supply filling complicates the loom, as such mechanism is and must be very sensitive.

In broad looms, which should be vru-n each by its own operator, I have found that the practical exhaustion of filling may be readily detected by the sight of the operator, and consequentlyl have devised a manually-controlled device that the operator just before complete exhaustion of the filling may move to start into operation vmeans for resupplying a running-shuttle box with filling, thus obviating the stopping of the loom to supply filling after practical exhaustion of filling from the run'- ning shuttle, and to stop the loom in case the filling breaks, which cannot be detected in advance, I employ a lling-fork. The fillingsupplying means made operative by the manually-controlled device contains but few parts and is novel and simple in construction.

In my novel loom the lay is provided with a cage for the reception of a spare shuttle con-A taining filling, and for the running shuttle I employ a shuttle-box movable between the race of the lay and the cage, said shuttle-box, as shown, having va depending receptacle for the spent shuttle, the latter shuttle entering said receptaclewhile the movable shuttle-box occupies its elevated position for the reception of the spare shuttle from the cage.

Believing that vI am the first to employV in an operative loom, with a weft-fork to stop the loom when the weft-breaks, filling-,supplying means that may be operated at any desired time by a manually-controlled device, I do not intend to limit my invention to exactly the form of filling-supplying .mechanism herein shown and intend to hold as Within the scope of my invention any usual devices 4now commonly employed in looms for supplying filling to be carried through vthe shed. i

It is not possible to use one and the same filling fork for stopping the loom on the breakage of filling and for insuring a fresh supply of filling prior to substantial exhaustion.

Figure l, in front elevation, shows part of the right-hand end of a loom with the -s-huttle. box E omitted. Fig. 2 is a plan view of Fig. l, showing the shuttle-box. Fig. 3 .is a righthand end elevation of the loom, Fig. 1 the shuttle-box E being in section on the line Fig. 2, and the shuttle omitted. Fig. 4 is a perspective detail showing the movableshnttle-box in position to receive a spare shut-Y tle, the spent shuttle being shown as having entered the spent-shuttle receptacle. Fig. 5 is a plan view of part of the left-hand end of the loom having the plain shuttle-box and showing a filling-fork to control `the stopping of the loom when the filling breaks. Fig. l6 isa detail showing how a spare shuttle `is supplied by hand to the spare-shuttle cage; and

lato

stop-motion rock-shaft C, located under the breast-beam and having the usual shipperhandle C and the box-rod C2, the pickers C4 C5,

and picker guide-rods C C? are and may be all as usual. In accordance with my invention the hand-rail of the lay is provided with a cage D for'the'reception of a spare shuttle @,the cage having a binder D pivoted thereon at D and acted upon by aspring D2. 'The free end of the filling a', led from the usual deliveryeye of the shuttle, is shown as carried over the cage and connected to some fixed stud or .device of the lay.

The movable shuttle-box'E, from which the running shuttle is thrown by the pickers across ther/race of the lay into the plain shuttle-box E atthe opposite end of the lay. (see Fig. 5) and back again pick after pick, is of peculiar construction-z'. e., it is composed of metal presenting ends 30 31, that lare guided in usual ways 32 33, rigid with relation to the lay. The shuttle-box E has a top cell e, that when the loom Vis weaving .and there is a sufficient supply of filling in the shuttle being thrown from said box occupies a position at the level of the race of the lay, as in Fig. 3. Under the cell e the boxv presents a shelf e2, (see Fig. 4,) sustained by depending arms e3 e* `of the box, the shelf and arms constituting the spent-shuttle receptacle. The shuttle-box rod C2 is attached to the under side of the shelf e2, and the rod in practice will be surrounded, as usual, with a spring e5. The shuttle-box cell has an ear on which is pivoted at e7 av binder e, the end of which coacts with the binderfinger Bto hold the dagger B7 in such position when the shuttle is in the box as to insure the proper running of the loom. -The binder @s is acted upon by a spring @12, fixed at one end to the'shuttle-box. The top of the cell ofthe shuttle-box at its inner end is cut out to form a space @13, said space making it possible to use a shorter and lighter weight-cage D and permitting the end of the spare shuttle to project from the cage and occupy a position partly in the cage e of the movable box E as the latter is lifted, as will be described and as shown in Figs. 3 and 4, to receive' the spare shuttle. The lower end of the shuttlebox rod C2 has a stud b, on which is pivoted a hook Z2', shown as having an arm b2, extended through a suitable guide b3, the weight of the said arm in the present instance. of this invention acting normally to keep said hook asvo in its normal inoperative position, as shown by full lines, Fig. 3, withits upper end in contact with a hand-lever mounted on a stud b5.

The shaft B has a disk provided with a groove 227, that receives a roller or other stud bs, carried by the short arm of a lever having its hub mounted on a stud Z210 at the loom end. As the shaft B is rotated the cam-groove b? moves the lever In from one to its other extreme position, Fig. 3, said lever rising and falling once during each two strokes of the lay, it risingas the lay is moving forward and fall- 'ing as the lay is moving backward. So long as the iilling in the shuttle is not exhausted to the point where the'missing of a pick would result in the production of imperfect cloth, which exhaustion may be determined by the eye of the operator looking at the running shuttle, the lever 69 will be moved by cam 67, but will do no'work; but the operator as soon as he or she sees that the filling is nearly exhausted engages the hand-lever b4, turns the same to move the hook b into its abnormal or operative position, (see dotted lines, Fig. 3,) so that as the lever b9 is raised its end will engage said hook and lift the boxrod and move the box E from the position Fig. 3 into the position Fig. 4E." The hook, lever, and its actuating means constitute one good simple and practical form of device for Y actuating the movable shuttle-box that it may receive a spare shuttle, and the hand-lever and hook constitute one good form of manually-controlled device for determining at will the exact time at which the running filling shall be discharged and new {illing supplied; but, as before stated, this invention is not limited to the particular construction shown for said manually-controlled device or the particular construction of the means shown by which to raise and lower the movable shuttlebox. When the manually-controlled device is moved, the shuttle-box is started upwardly while the running shuttle is crossingfrom the movable shuttle-box end to the plain box end of the lay, and the then empty cell e of said box is placedV opposite the cage containing the spare shuttle, and the spent shuttle in its flight across the loom from the plain shuttle-box end of the lay enters the spent-shuttle receiver, as shown in Fig. 4, and while the movable box is opposite said ,cage the spare shuttle is moved from the cage into the cell e, as will now be described.

The lay a is provided with ears c, that sustain a rod c', on which is mounted a picker c2, that is normally held in its position farthest from the movable shuttle-box E by a spring c3. (Shown in Fig. 2.) The picker 02 has joined to it one end of a cord c4, thatv is connected at its other end with a drum c5, carried by a shaft c, rotatable in suitable bearings c2 (see Fig. 3) of the lay, said shaft at its lower end havinga smaller drum c7, with which is ILO attached one end of a second cord cs, led through a hole in the lay and provided, as shown, with a hook c. The action of the spring 03 on the picker o2 winds the cord 08 on the pulley c7. Now whenever the movable shuttle-box is raised to provide for supplying fresh filling thereto an arm CZ, (see Fig. 3,) carried by the shuttle-box E, meets the under side of the hook 09 as the lay is moving forwardly and lifts said hook and causes/,it rto be engaged by the catch c?, carried by the breastbeam, so that as the lay is moved on its' back stroke the cord cs is held, Vand consequently the shaft c is turned quickly and the cord c* is wound on the pulley o5, and in so doing the picker o2 is moved to the right, Fig. 2, pushing the spare shuttle from the cage into the empty cell. The free end of the binder D is shown as outturned, so that the end of a spare shuttle may be inserted easily into the cage while the lay is in motion.

The shuttle-box E has an attached auxiliary binder e, (see Fig. 4,) that is extended downwardly from its point of connection with the shuttle-box and is provided at its lower end with a toe e121, that is acted upon by the spent shuttle'as the latter comes back onto the shelf e2 of the spent-shuttle receiver. VThe binderfnger b5 rideson the upright part of the auxiliary binder as the shuttle-box is raised to receive the spare shuttle, thereby preventing the action of the dagger to stop the loom when a fresh shuttle is being supplied. They vand the finger passes from contact with the auxiliary binder and comes in operative relation on the usual binder es. Inasmuch as the short end of the auxiliary binder contacts only with the rear end of the spent shuttle, as shown in Fig. t, when said shuttle fully cnters the spent-shuttle receiver the spentshuttle may be easily discharged from the shelf e2 and leave the loom in the movement of the lay. The shaft B has usual binder-fingers, as B5, and a dagger B7, that acts in usual manner to stop the loom when the shuttle fails to be properly boxed.

The lay carries a filling-fork f, that feels during each movement of the lay for the filling a, l(see Fig. 7,) which is supposed to be laid upon the race of the lay after each crossing of the shuttle from one to its opposite box,

and when the fllling is absent the fork enters the space f and lowers the dog f2, so that as the lay completes its forward stroke in case the lling is absent said dog meets and turns an arm fil, pivoted on a shield g4, causing a pin k12, carried by said arm,n to meet and knock off the nger t and turn the rock-shaft It', sustained under the breast-beam in a suitable bracket /zz connected therewith, causing an arm h3, having a pin, (see Fig. 7,) to meet the arm L, fast on the rock-shaft h5, and turn thesame that the latter may meet the knockoff lever It and turn `the same to effect the release of the usual shipping mechanism, that when released coacts with the usual driving -ticularly described, and instead of the particular mechanism shown in detail Fig. 7 I may use any other suitable stop-motion mechanism whereby when the filling breaks or is absent from the lay when the `feeler descends the loom will be stopped. V
