To all whom it may concern.-

Beit known that I, HENRY TfHUNNEw'ELL,

the filling-carrier is engaged at its tip and base or head and transferred from a hopper or lling-feeder to the shuttle, and in order to prevent the tip from being unduly de pressed or dropping below the shuttle-bottom a tip-holder, so called, has been employed. This tip-holder projects beneath the tip of the filling-carrier and yields as the latter is inserted in the shuttle, holding the tip up in proper position. Should the tip drop, it is very apt to break the filling-thread or to be caught in the slot of the lay, and the tip-A holder is designed to prevent these faults. In actual practice, however, the tip-holder will sometimes break the thread or otherwise injure the filling, and if it is improperly set it is apt to mar the shuttle by striking it on the side. There is also a tendency to tilt the filling-carrier up out of the shuttle as thelay moves back after a transfer of lli'ng.

My present invention has for its object the production of novel means for preventing the dropping or displacement of the tip of the filling-carrier which is inserted in the shuttle at the time of transfer Without any of the obj ectionable features hereinbefore referred to.

Instead of acting directly upon the incoming filling-carrier I provide means for acting indirectly thereupon by or through the medium of the outgoing or ejected filling-carrier, and not only is the tip of the incoming fillingcarrier properly guided and supported as it is inserted in the shuttle, but the ejected fillingcarrier is prevented from falling with its tip upward. Thereby the thread will not tend to unwind and leave a long trailing end,which is apt to be carried back into the cloth, but the smart blow with which the ejected Iillingcarrier is pushed out of the shuttle acts to draw the thread end out of the shuttle-eye, it being usual to sever automatically the thread between the cloth and the shuttle-box in looms of this type.

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

Figure l is a front elevation of a portion of the right-hand side of a loom provided with automatic iilling-replenishing mechanism with one embodiment of my invention applied thereto. Fig. 2 is a transverse section thereof on the line 2 2, Fig. 1, looking toward the left. Fig. 3 is a similar View, but showing the parts in different position, the incoming` filling-carrier having just been inserted in the shuttle and the ejected filling-carrier being shown as just about to drop from the lay be neath the shuttle-box; and Fig. 4 is a top or plan View of the device for effecting the control of the tip of the incoming filling-carrier and governing the position of the one ejected.

Of the various parts shown in the drawings the lay A3, cut away at l0 below the replenishing shuttle-box BX, the filling feeder or hopper comprising connected rotatable disks ct'and a to support between them the fillingcarriers b, the transferrer f', having a lateral arm provided with a downturned end 22 to engage the tip of the filling-carrier to be transferred, the bunter C2 on the lay, and the dog m15, moved into position to be engaged by the bunter when the operating or controlling rock-shaft d is turned, may be and are all substantially as in United States Patent No. 664,790, datedv December 25, 1900, and operate ina manner-well known to those'skilled in the art to which this inventionfpertains. At the time of transfer the transferrer f engages the vbase'or head of the filling-carrier and the part 22 engages the tip, the filling-carrier being thereby conveyed from the feeder or hopper into the shuttle S, which is open 'from top to bottom to receive the incoming filling-carrier and to permit the discharge of IUU the spent or exhausted filling-carrier. The latter is ejected by the smart blow with which it is struck by the incoming or fresh fillingcarrier, and heretofore the tip of the latter has been supported at time of transfer by a yieldingly-mounted tip-holder extended beneath it, as in the patent last referred to, the ejected filling-carrier dropping freely through the cut-away part l() of the lay into a box or other receptacle.

In accordance with my present invention the hub g of a depending arm g is lixedly secured to the outexl end of the fulcrum-stud j", on which the transferrer rocks, said arm at its lower end having a boss g', through which a bolt g2 is extended laterally. This bolt passes through the hub g3 of a second arm g4, extended toward the back of the loom, and by means of the bolt the free end of the arm can be adjusted vertically relatively to the lay. By adjusting the depending armg on the studfthe free end of the arm g4 can be regulated toward or away from the front of the loom, as will be obvious. A rocking rod or shaft hx is extended through the arm g4 near its free end in parallelism with the lay, and a sleeve 5, Fig. 4, is pinned to the shaft adjacent the inner face of the arm, inclosing a spring SX, one end of which is attached to the sleeve and its other end is secured to the arm. The shaft projects through the arm g4 and has secured to it adjacent the outer face of the latter a tip-support or finger h, having a lug lz', which is normally held against a stop projection g5 on the arm by the action of the spring SX. The sleeve and tipsupport prevent longitudinal movement of the rock-shaft hX in the arm g4. At its inner end the rock-shaft has secured to it a support h2 for and to momentarily engage the base or head of the ejected filling-carrier, said support being shown herein as a loop of stout wire and slightly concaved at its rear end, as shown in Figs. 2 and 3.

It will be seen that the tip and base supporting members h and h2 extend into the cut-away part lO of the lay and beneath and just below the open bottom of the replenishing shuttle-box BX when the lay beats up and is in position for a transfer of filling to the shuttle S, the adjustments of the arms g and g4 permitting very accurate positioning of the parts. Now when the incoming filling-carrier enters the shuttle it engages the fillingcarrier therein to be ejected and pushes it down out of the shuttle and through the bottom of the shuttle-box, and as the ejected filling-carrier descends it is engaged at its tip and base by the supports 7L and h2, respectively. These act to momentarily retard or arrest the movement of the ejected fillingcarrier, but enough to prevent any dropping of the tip of the incoming one, and then the shaft hx turns to move the supports from full to dotted line position, Fig. 3, due to the impact upon them of the ejected filling-carrier, and the latter drops from said supports. In

Fig. 3 the ejected filling-carrier is indicated by dotted lines at bx just at the instant it leaves the supports h and h2, and it falls in a substantially horizontal position to the box or other receptacle provided for it. As soon as the supports have performed their Work the spring 3X returns them to normal position. Thus not only is the tip of the incoming filling carrier supported indirectly by or through the medium of the outgoing filling-carrier, but the latter is so discharged or ejected that it will not descend tip uppermost, and thereby permit a long trailing piece of filling to unwind therefrom.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
