Abstract: 923,685. Unwinding yarn packages. H. BUDDECKE. March 14, 1961 [March 31, 1960], No. 9215/61. Class 120 (2). [Also in Groups XVII and XXXV] A method of withdrawing yarn from a yarn pack having transversely extending loops of yarn on a parting strip wound into a roll, comprises withdrawing the yarn in the longitudinal direction of the strip after the loop of the yarn to be next withdrawn has been brought by the motion of the yarn pack or roll to a spatially fixed point and has been exposed or released from the parting strip. In Fig. 5 the parting strip 9, separating the layer of loops 8, is withdrawn from the roll 10 by a guide roller 48 and a take-up reel 14, the reel 14 being controlled to draw the strip 9 off the roll 10 according to the rate of consumption of the yarn. The yarn is continually drawn off at the same level by resting the roll 10 on a table 49. To prevent balling or tangling and to cause the amplitude of the loops to become uniformly narrower, light braking elements 55 may press on the loops as shown. Alternatively, Fig. 6, a run-off table 49 vibrating in the direction 60 may be used. In a further embodiment, Fig. 7 (not shown), the released loops of yarn are fed on to a perforated run-off table from which air is extracted by a fan. In Fig. 1 the loops 8 are drawn off in the direction of the arrow and the parting strip is wound on to a take-up reel 14. To ensure that the loops 8 are always drawn off in the same plane a cranked arm 38 carries a roller 12 resting on the package 10. The other arm of the cranked arm carries a stop 36 disposed between two electrical contacts 35 in a circuit controlling the switching on, and direction of rotation of, a motor 34. The motor 34 drives screw means raising and lowering the axis of the roll 10 in a manner maintaining a constant position for the plane of draw-off of the loops 8. Specifications 759,133, 819,591 and 872,649 are referred to.

Title: Improvements in and relating to visual mine signalling devices
IPC: B66B19/06
Filed: 1920-04-08
Abstract: 165,554. Ritchie, D. M., Ritchie, W., and Smith, J. April 8, 1920. Mechanical telegraphs; mine and colliery signals.-In mine signalling apparatus having a signalling pointer and a cautionary pointer carried round therewith, arrangement is made whereby the signalling pointer is returned to zero when the winding-engine moves, but the cautionary pointer is returned only when the engine has made a movement and stops. The signalling pointer is also zeroized by the first impulse of a succeeding signal, and signals given during the wind are cancelled when the engine stops. The signal pointer B mounted on a spindle provided with ratchet-wheel 3 has a projection 20 engaging and moving the cautionary pointer C which is mounted on a sleeve provided with a ratchetwheel 6. The ratchet-wheel 6 is engaged by a detent lever 12 pivoted at 14. The ratchet-wheel 3 is engaged by a detent lever 11 pivoted at 13. When a sliding rod D is raised by a signalling impulse, a cross-bar 17 raises a weighted rod 18 connected to the piston of a dash-pot 19. Rod 18 momentarily raises lever 11 allowing the signal pointer to return to zero under the action of a weight 9 and cord 7 passing round a pulley 2. On descent of the rod D, a pawl 16 engages and rotates the ratchet-wheel 3, a second pawl 15 limiting the movement to that of one tooth. A governor F, or a centrifugal pump or other device driven from the winding-engine, is arranged to lower a rod E when the engine is running, and raise it when the engine stops. Rod E carries projections 24, 29, the former raising the detent lever 11 as the rod descends, thus returning the signalling pointer to zero, the latter raising detent lever 12 as the rod rises, thus freeing the ratchet-wheel 6 and returning the cautionary pointer to zero under the action of a weight 10 and cord 8. The levers have pivoted end pieces 22, 27, 28 which move the levers in one direction only, but yield to the passage of the members 18, 24, 29 in the opposite direction. A lever 25 situated above the members 27, 28 is rocked when the detent lever 12 is raised as the engine stops, so that the lever 11 is also raised. Any signal given whilst the engine was running is thus cancelled.
