WEFT-REPLENISHING MECHANISM FOR LOONIS- SPECIFICATION forming part of Letters Patent NO. 794,377, dated July 11, 1905.

Application filed September 17, 1904. Serial No. 224,853.

To (bi/Z Hill/07771 it wen/y concern:

Be it known that I, FELIxODoNNELL, a resident of the cityof Pawtucket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Weft-Replenishing Mechanism for Looms; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form. a part of this specification.

This invention relates to looms, more par ticularly to that class which are provided with automatic weft-replenishing mechanism for weaving whereby a fresh supply of filling is automatically transferred from the magazine to the shuttle when the supply of filling has been exhausted or the thread broken.

The object of the invention is to provide improved mechanism of very simple construction and of positive action and which may be readily attached to the ordinary loom now in use, if desired.

The invention consists of other novel features and arts and combinations of the same, as wil be fully described hereinafter and then pointed out in the appended claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all views.

In the drawings, Figure 1 represents a transverse section of the loom,showing a sufficient portion to be understood, with my improved device attached thereto, showing the mechanism of the automatic filling-replenishing apparatus in its normal position, section taken on line 1 1 of Fig. 3. Fig. 2 represents an enlarged view of the automatic filling-replenishing apparatus in the position taken when driving a bobbin into the shuttle. Fig. 3 is a front view of a portion of the loom, showing my device attached thereto, partially in section. Fig. 4 is a perspective view showing a detail of the bell-crank and the actuating-pawls attached thereto. Fig. 5 shows the position of the cams and levers as a fresh bobbin is about to be struck into the shuttle.

Referring to the drawings, at 1 is the loom breastbeam, and 2 2 the end frames, on which frames are set the ordinary loomarch 3.

At 5 is the rotatable magazine or fillingfeeder. All around the periphery of this wheel are fixed spring-fingers 6, each pair of fingers being especially designed and adapted to engage one end of a cop or filling-carrier and firmly support it in a horizontal position while it is being carried around under the foot of the plunger. This wheel 5 is mounted on and fixed to the shaft 4, which shaft is supported to turn in the bearings 6, (see Fig. 3,) said bearing being supported from the frame 2. This shaft extends out beyond the copwheel and has mounted upon it the fillingend support 7 and the filling-end holder 8. The ratchet-wheel 9 is also mounted on and fixed to the shaft 4, so as to turn with it and the filling-carrying wheel. The teeth in this ratchet-wheel are preferably made square and spaced to correspond to the spacing of the cops on the wheel 5, so that each time the ratchet is moved ahead one tooth a fresh bobbin is brought into position to be struck down into the shuttle, as will be hereinafter described.

At 10 is a bell-crank lever mounted to turn freely on shaft 4, said lever having a horizontal arm 11 and a depending arm 12. On the end of arm 11 are pivotally mounted the two pawls 13 and 14 on pins 15 and 16. Fixed to the outer end of this arm are the fiat springs 17 and 18, that press on these pawls 13 and 14, respectively, to hold them normally into engagement with the teeth of the ratchetwheel 9. On the pawl 14 is fixed a finger 19, that extends up and over the top edge at 20 of its supporting arm 11. By pressing downward on this portion 20 of the finger the pawl 14 may be thrown out of engagement with the teeth of the ratchet-wheel 9, and the arm 11, with its pawls, may then be carried downward for another tooth into the position shown in Fig. 2 without turning the ratchet-wheel 9.

The transferrer comprises an arm or lever 25, pivoted in an arm 27 of bracket 24, said lever having a plunger-spindle 22 pivoted thereto at 25. Said spindle is provided with a plunger-foot 21 and is free to reciprocate in a bearing 23, pivotally supported at 23 by bracket 24, whereby the same is free to adjust itself to the circular movement of the upper end of the spindle. To the opposite end of the lever at 28 is pivoted the upright lever 29. The upper end of this latter lever extends up above the pivoting-point, forming a hook to which the spring 30 is attached.

At 31 is the ratchet-wheel-locking pawl that is also pivoted to the bracket at 26. The outer end of this pawl is shaped to fit the square notches in the ratchet-wheel and securely lockv said wheel and the cop-wheel from moving in either direction while the filling is being driven into the shuttle. The opposite end of this pawl extends back of the pivoting-point at 32 and engages the under side of the plunger-lever 25 by the screw 33, which may be adjusted to regulate the height of the locking end. This pawl is held up against said lever by the tension of spring 30, which spring serves the double purpose of holding this pawl in position and also to ex ert a tension on the upper end of the upright lever 29 to swing its lower end into position for the purpose hereinafter specified.

At 33 is the ordinary weft-fork mounted to slide in the usual way on the breast-beam, and at 34 is the usual two-arm cam-actuated lever that operates the fork when there is no weft-thread to raise its end out of the path of said reciprocating lever. One end of the arm 35 engages the rear end of the fork-slide and is fixed at its opposite end to the shaft 36. This shaft extends along under the breast-beam and has the depending arm 37 fixed to its opposite end.

At 38 is the crank-shaft, on which is mounted the rotating cam 39. Above this cam is located the cam-bar 40, which is held up and just out of engagement with said cam by means of the latch 41. This latch may be withdrawn from the notch 42 in the end of the cam-bar and allow said bar to drop and engage said rotating cam when the weft-fork fails to find the weft-thread, which is done through the arm 44, connection 45, arms 37, shaft 36, and arm 35 as the weft-fork slide is driven back in the manner above described. When the cam-bar drops, the hooked portion 47 in the lower end of the lever 29 is drawn in by the tension-spring 30 and hooked over the pin 46, as shown in Fig. 5. As the cam 39 rotates in the direction of the arrow the cam-arm 40 is thrown quickly upward, carrying with it the upright lever 29 and transferrer lever 25, driving the plunger down and forcing a fresh cop 49 into the shuttle 50. As soon as the cam portion 39 has carried the cam-bar 40 to its extreme upward position the latch 41, under tension of the.

spring 52, engages the notch 42 and prevents the cam-bar from falling again. Just at this point the rotating cam 51 engages the downwardly-extending end 56 of the lever 29, pushes it over and disengages the notch 47 from the in 46, allowing this lever 29 to descend an the plunger and transferrer-lever to rise under tension of the plunger spring 22 encircling. spindle 22, and by this motion the locking pawl 31 is withdrawn from the ratchet-teeth, the bell-crank released and,

under tension of its actuating-weight 53, is drawn from the position shown in Fig. 1 over against the stop and into the position shown in Fig. 2, feeding the ratchet-wheel around one tooth and bringing a fresh cop into position under the plunger.

The operation of the device is further explained as follows: When the fork 33 fails to find the weft-thread, it is driven back in the usual way by the lever 34, and through the arms 35 and 37 and connection 45 the pawl 41 is withdrawn from thecam-bar 40, which latter is allowed to drop and ride on the cam 39. When this bar drops to the lower portion of said cam, the upright lever 29 swings in by the action of the spring 30 above and the notched portion 47 engages the pin 46. As the cam revolves the quick rise in the cam acts on the bar 40 to force it quickly upward, and as lever 29 is hooked onto the pin 46 it is also carried upward with a sudden impulse, and by this upward motion the rear end of the locking-pawl is allowed to rise and, under tension of spring 30, throws the locking end into engagement with the ratchet-wheel, se-

curely holding it and the cop-wheel from turning until said pawl has been again withdrawn. As the long end of the transferrerlever 25 is thrown downward the set-screw 54, shown in said lever, engages the turnedover portion 20 of the finger 19 and forces it down onto the top edge of the arm 1]., which act raises the end of the pawl 14 out of engagement with the teeth of the ratchet-Wheel and by a further downward movement of lever 25 the bell-crank lever is carried with its two pawls 13 and 14 downward from the position shown in Fig. 1 to that shown in Fig 2, in which latter position it will be seen by the dotted lines in Fig. 2 that pawl 13 has been carried down one tooth in the ratcl1et-wheel. Simultaneously with the movement of lever 25 the spindle 22 is depressed, and the plungerfoot 21 thereof forces a cop out from engagement with the carrier and into the shuttle, as heretofore described. When the transferrerlever 25 has been released and raised again, the weight 53 draws the lower arm of the bellcrank up to the stop 55, which feeds the copcarrierahead one tooth, bringing a fresh cop into position to be struck down into the shuttle. The mechanism now stays in this, its normal position, which is that represented in Fig. 1, until the thread breaks or the filling runs out of the shuttle, when the operation above described is again repeated, driving fresh filling into the shuttle and at the same time ejecting the bobbin from the shuttle previously contained by it.
