Abstract: 23,312. Kay, J., Rossetter, W., Hoyle, E., and Buss, A. A. Oct. 8. Shuttles, changing bobbins and the like in, automatically; picking- motions; shuttles, positioning for weft-replenishing.-When the weft fails, the speed of the loom is reduced by mechanism somewhat similar to that described in Specification 14,524/02, and a filled and threaded weft carrier or case or core shuttle from a magazine 37, Fig. 3, is pushed through the side of and into the working shuttle 39, simultaneously ejecting the spent case through the opposite side, after which the loom resumes its normal speed, the picking-mechanism having been thrown temporarily out of action. A weighted feeler 48 is used to stop the loom when the last weft case in the magazine has been brought into position for transference into the working shuttle, and shuttlepositioning mechanism is also employed. When the weft - fork mechanism 1, 2, Fig. 2, is actuated, and the spring handle lever 3 is rocked, the ordinary spring handle 4 is released from its notch and, by means of its spring assisted by a coiled spring 7, Fig. 3, moves a sliding rod 8, Figs. 2 and 3, and bracket 8<a> to the right. This rod causes the picking-tappet to be disengaged, and by means of a slotted bracket 60, lever 61, and link 64, causes the strap-fork 9 to. move the driving-belt from the fast pulley 10 to an intermediate pulley 11. This pulley is loose on the driving-shaft, and is connected by reduction gearing to a spur-wheel, which is loose on the tappet-shaft 17 but drives it by means of friction pawls, the tappet-shaft then driving the usual driving-shaft at a reduced speed. When the belt is on the fast pulley 10, so that the driving-shaft is driven directly, the friction pawls are brought out of engagement with the groove in which they wedge. The rod 8 also causes a backward movement of a lever 13, whereby an arm 14 moves a stud 15 into engagement with a worm 16 against spring action. The worm 16 is loosely mounted on the tappetshaft, but is provided with a crank 20 carrying a stud 19 engaged by a plate 18 fixed on the shaft, whereby the worm is rotated, and, when it is engaged by the stud 15, is moved axially against the action of a spring 160. The stud 19 is thereby moved into position to actuate a crank lever 22, whereby a notched lever 27 is brought into the path of a stud 30 on the laysword 31, and a rod 41, Figs. 3 and 5, is raised, thereby causing a lever 42 provided with a curved cam-plate 410 to be oscillated, the camplate being thus brought into the path of the knob 43 of a positioner 44 passing through a slot in the lay. The positioner is thus oscillated, and its upper extremity, which is shod with hide, fibre, &c., then engages the shuttle tip 46 and forces it into the proper position. The stud 30 engages the notched lever 27, and thereby oscillates a lever 32, whereby a pusher slide 34 is moved and feeds a weft case from the magazine into the shuttle. A crank bowl 21 then engages the lever 13 and returns it together with the rod 8 &c. to normal position, thus causing the re-engagement of the picking- tappet and forcing the spring handle 4 to the left into its notch, whereby the driving-strap is moved on to the fast 'pulley and the loom is driven at its normal speed again. Shuttles.-Rings or other clipping-devices are provided at each end of the weft carrier or case and in the interior of the shuttle body.
