Title: Improvements in or relating to weft inserting devices in looms for weaving
IPC: D03D47/00
Filed: 1925-01-19
Abstract: 227,865. Moya, R. G. Jan. 18, 1924, [Convention date]. Weft inserters not carrying bobbins, cops, and the like, looms with. -The weft from one or more bobbins 18-20, Fig. 3, passes through an eye or thread guide 21 thence through an eye 22 on a flexible arm or coiled wire 23 serving to take up slack and finally through an aperture 29, Figs. 4 and 5, in the end 28 of a weft-carrying arm 10, Figs. 3, 4, 5 and 6, which inserts the weft in loop form. The arm 10 may comprise a straight rod, or a flexible steel strip guided by rollers 11, 12 and connected to an arm 9 on a shaft 8, which is oscillated by lever mechanism from an eccentric on the crank shaft, this lever mechanism including a universal joint and crank mechanism. On the return movement (to the right) of the arm 10, the weft 50 is drawn under a spring 30 and thereby tensioned. The weft-carrying arm 10 has a cut-away portion 35 so that the weft is slightly separated from the arm at this portion, and it may be engaged by a rod and retained thereby at the left-hand selvage. Or it may be engaged by a selvage-forming thread from a bobbin 39 rotatable in a box 41 by a plate 47 on a shaft 42 driven by belt gearing. The plate 47 is normally kept stationary, the driving-belt slipping, by the engagement of a pin or pawl 46 on a spring-controlled plate 44 with a tooth on the plate. When the arm 10 moves to the left, it actuates the plate 44 and releases the plate 47, which then rotates the bobbin 39, and a tooth 40 on the bobbin catches the weft thread 50 and winds it around the selvage-forming thread from the bobbin.

[Also in Division G3] Half-digits of a digital clock are marked plates carried by a cage 2 and spring-pressed anti-clockwise so that as the cage is stepped round and the edge of a plate becomes free from a ledge 7 the plate springs up to reveal the next digit. Drive to the lowest denomination is effected by a spring-pressed reciprocating pawl, carry being effected by a further spring-pressed pawl 34, Fig. 3, falling off the high point of a cam. The units of hours wheel HU is carried from 3 to 0 in the passage from 23 hours to 00 hours by spring- pressed lever 32 which is raised by cam 36 until at the hump 37 the lever 32 drives the cam sharply through the necessary steps. The drive to the minutes wheel is effected by the simultaneous closure of a pair of camoperated switches (Fig. 6, not shown). The clock is normally driven from the mains with synchronization from a master clock. If the mains fail the synchronization pulses drive a gear 75 along a helical path to the left. Reconnection of the mains energizes motor 72 to drive shaft 73 through a slipping clutch 74. A cam 76 on the shaft 73 then operates contacts 78 the necessary number of times to restore the digital clock to correct indication, at which time gear 75 abuts a flange 82 to release the clutch 74.

Title: Device for unwinding the thread waste from exhausted tubes and bobbins
IPC: B65H73/00
Filed: 1951-01-30
Abstract: 684,007. Stripping waste from bobbins. MASCHINENFABRIK SCHWEITER AKT.-GES. Jan. 30, 1951 [Feb. 17, 1950], No. 2279/51. Classes 120(ii) and 120(iii) In a re-winding machine, a thread waste take-up drum which rotates with the winding apparatus is arranged in the space between the bobbin to be unwound and the bobbin to be wound, and means are provided to seize the leading end of the cut-off remnant of yarn of an exhausted bobbin above a traversing thread guide eyelet of the unwinding apparatus and to convey it to the thread waste take-up drum. In the machine shown, at each winding station thread is drawn off a bobbin 5 through a traversing eyelet 6a and a fixed eyelet 6 and wound on a bobbin 7 by a winder 2. A thread-waste take-up drum 8 is mounted between bobbin 7 and a thread piece 4 and is driven from winder 2 through worm gearing. A snatch arm G is rotatably, mounted at 22 on a lug of a plate 13 pivoted at 9; a straight-toothed gear 23 fixed to arm G meshes with a stationary skew-toothed gear 10 so that when plate 13 is rocked by a rod 17 nippers Z at the end of arm G describe a helicoidal movement as shown at 12, Fig. 1. In the lowest position of arm G the nippers are automatically held open; as the arm commences its movement, the nippers close under spring action. When the delivery bobbins are changed a cam 21 rotates, forces rod 17 downwards, and so operates snatch arm G at the moment when piecer 4 has pieced on the thread of a new bobbin 5 and cut off the thread of the exhausted bobbin 5a. The thread end of bobbin 5a is caught by nippers Z and carried to a position behind drum 8; on the return movement of arm G the thread engages drum 8 and is either nipped between the conical surface thereof and its cover plate 60 or adheres to thread already wound on the drum. As the winder is set in motion again, drum 8 begins to rotate and winds up the waste thread from the exhausted bobbin 5a. The end plate 60 of drum 8, Fig. 10, is held in position by engagement of spring wires 65 with notches 66 in bolts 62 riveted to plate 60, and can thus be slipped on to and pulled off the drum. The drum is floatingly mounted so that it can be stopped by hand while the machine is running, for removal of a coil of wound waste threads after plate 60 has been pulled off. Instead: of using a snatch arm, the waste thread end may be intercepted and transferred to the drum by means of a suction or blowing device.
