Title: Method for skeining hanks having a relatively large width and apparatus for automatically carrying out the method
IPC: B65H54/62
Filed: 1968-07-29
Abstract: 1,241,331. Winding hanks. STABILIMENTI TESSILI ITALIANI S.p.A. 29 July, 1968 [21 March, 1968], No. 35999/68. Heading D1J. A method of tying up a hank of relatively large width whilst the hank is on the reel on which it has been wound comprises the causing of a thread H, Fig. 1, to be placed adherently to an inner face of the hank, causing the thread H to be drawn up at equal intervals through the hank so as to form protruing loops 0, passing an upper thread L through the loops 0, and knotting the threads H, L to each other at the edges of the hank as at K. This process is repeated for the other hank that may be on the reel. The apparatus for carrying out the process comprises a box Q, Fig. 7, mounted on rails (not shown) above and parallel to the reel axis. The box carries a motor 38 that drives (a) first gearing for causing the box to move in steps, with a pause between each step, along the aforesaid rails; (b) second gearing for causing a hook 21 to make a scythe shaped reciprocating plunge down through the hank whilst the box Q is stationary; (c) third gearing causing a transfer hook 44 to move the resulting loop O off the hook 21 and onto a collector 2 to which the thread L is tied; (d) means causing a hammer 37 to repeatedly strike the collector 2 to vibrate it and so cause the loops to slide off the collector 2 and onto the thread L. To enable the loops O to pass down the collector 2 the collector 2 is loosely mounted in a shell 13 the lower generatrix of which is open, the vibrations delivered by the hammer 37 vibrating the collector 2 sufficiently to allow the loops O to slide along in the resulting air gap between the collector 2 and the shell 13.

Abstract: 429,293. Winding-apparatus. MAVOR & COULSON, Ltd., and MAVOR, J. B., 47, Broad Street, Mile End, Glasgow. Dec. 28, 1933, No. 36478. [Class 78 (v)] [See also Group XXI] In haulage gear, particularly for coal cutters and other machines requiring a low load speed and a high light speed, the low speed is transmitted from the power shaft 8 by pawl-and-ratchet gearing, and the high speed by direct pinion gearing. The ratchet gearing comprises a spring-pressed pawl 17 carried by a casing 15 mounted loosely on a shaft 11. The casing 15 is oscillated by a connecting-rod 13 actuated by a crank-pin 12 carried by a worm wheel 9. The stroke of the pawl 17 can be adjusted by a shield 19<a> on a disc 19 adjustable by a hand-wheel 20. Backing of the ratchet wheel 16 is prevented by a detent 21 which can be kicked out of action by means shown at 22. The direct pinion gearing for imparting high speed to the shaft 11 comprises a worm-wheel 10 and pinions 23, 24 and 25, the latter being fixed to the shaft 11, and a clutch being introduced between wheels 10 and 23. The rotation of shaft 11 is transferred to the drum 1 by a reversing gear consisting of pinions 28 and 30 permanently in mesh with a toothed ring 27 on the inside of the drum 1, and a pinion 29 permanently meshing with the wheel 30. The pinions 28, 29 and 30 are journalled in a cage 31 swingable about the drum shaft 2 under the control of a pin 32 working in a slot 33. Swinging of the cage 31 by manually-operated means 34, 36, 37 to one side or the other brings the pinion 28 or the pinion 29 into engagement with a pinion 26 on the shaft 11, thus imparting forward or reverse motion to the drum. This reversal mechanism can be located wholly or partly within the drum 1. Bollards 3<a> .. 3d are disposed about the drum to facilitate leading the cable 4 in any required direction. The bollard pulleys may have flanges 3<1>, 3<11>, Fig. 3, which project into annular recesses 5<a>, 6<a> in the frame plates 5, 6 to prevent the cable becoming wedged between the pulley and the frame.

Abstract: 835,041. Thermallyactuated valves. WALTON ENGINEERING CO. Ltd., SPICER, H. E., CROSBY, R., and SIMPSON, F. A. Nov. 25, 1957 [Dec. 3, 1956], No. 36956/56. Class 135. A valve consisting of an inlet 6 and outlets 7, 8 controlled by a rotary closure member 4 has a linearlyexpanding temperature - responsive element 9 and coupling means for converting the linear movement to rotary movement. As shown, the temperature-responsive element consists of a chamber containing a semi-liquid substance which, on expansion, transmits through a sealing diaphragm and piston loaded by a spring 10 a force to a rod 12 which carries a radial pin 14 coacting with a cam slot 17 in a sleeve 16 which is non-rotatably mounted in the housing. Thus, axial movement of the rod 12 causes rotary movement of the closure member 4 when the pin 14 is situated in a helical portion of the slot 17. The slot 17 also has a portion or portions parallel with the axis of the rod 12 whereby over part of the range of movement of the latter no rotation is imparted to the closure member 4. Axial adjustment of the sleeve 16 is provided by a screw-threaded extension 20 and nut 21. The valve is suitable for use in controlling the flow of coolant from an engine, one of the outlets 7, 8 being connected to a heat-exchanger whilst the other is connected to a by-pass leading back to the engine. In a modification, the valve is arranged to be operated also in the event of overheating and for this purpose a fusible plug is so arranged in the valve housing that when an excessive temperature is reached it releases a spring-loaded rotary member situated outside of the housing and having a pin-and-slot connection with the sleeve 16 whereby the latter is moved axially to operate the valve.
