Title: Method of and apparatus for supervising the running of automatic thread winding machines
IPC: D01H13/32
Filed: 1951-03-28
Abstract: 740,685. Winding machine control means. REINERS, W. March 28, 1951 [May 22, 1950], No. 7212/51. Classes 120 (2) and 120 (3). In a method of supervising the running of a thread or yarn winding machine having automatic spool changing mechanism and thread tying means, the interruptions in the winding operation caused by thread breakages and by thread tying failures are automatically de-. tected, the detection of a predetermined number of thread breakages automatically initiating remedial action to remove the cause of said breakages and the detection of a predetermined number of tying failures automatically operating a warning device. In the arrangement shown movement of the feeler 6 in consequence of thread failure closes the contacts 14 and 22. The latch 31 is withdrawn from disc 32 and the shaft 36 is set in motion. This causes the package 3 to be lifted from the driving drum 2 and initiates a thread tying operation in known manner. At the same time a thread break is indicated on instrument 27. After the thread tying operation has been completed the knotted thread is tested by the feeler 7 and should it fail contacts 16 and 16a are closed and a faulty thread tying operation is recorded on the instrument 47. After a predetermined number of thread breakages the pointer of instrument 27 engages the contact 28 and, through the circuit 29, 30, changing of the supply bobbin is initiated. The instrument 27 may be adapted to indicate the number of breakages in a single supply bobbin or in a number of such bobbins. In the case of the single bobbin the pointer is caused to return to its zero position after bobbin changing. It can thus be used to give an indication of the rate of occurrence of thread breakages. Should a predetermined number of thread tying failures occur the pointer 48 of instrument 47 engages the contact 49 and operates a warning device 46. Repeated tying failures are prevented from operating the thread breakage instrument by the electromagnet 44 breaking the thread breakage circuit. Further means may be provided by which should the thread from the supply bobbin be missing or should the supply bobbin have insufficient thread thereon to complete a new winding-on spool the supply bobbin is automatically changed for a new one.

Abstract: 1,065,071. Endless belt conveyers. WESTINGHOUSE AIR BRAKE CO. Feb. 21, 1964 [Feb. 26, 1963], No. 7427/64. Heading B8A. A troughing idler assembly 10, as shown in Fig. 1, for an endless belt conveyer is suspended from wire rope side frame members 11, 12 and consists of a roller assembly 13 which comprises a centre roller 16 flanked by wing rollers 14, 15 supported by and swingable with respect to cradle frames 17, 18, slideways 32, 32a in end plates 22, 22a providing limited arcuate canting of shafts 30, 30a. The wing rollers 14, 15 taper uniformly from their inner to their outer ends at an angle of from 2 to 8 degrees. When the belt 36 moves in the direction of the solid arrow (Fig. 1) the wing rollers 14, 15 assume the full line positions in which they are canted forwardly in the direction of belt travel and have a training effect tending to centre the belt 36 on the assembly 10. When the belt 36 travels in the direction of the broken line arrow the wing rollers 14, 15 assume the broken line positions and thus still act to centre the belt 36. Fig. 5 (not shown) illustrates a modification in which wing rollers 50, 51 are not tapered uniformly but are diametrically expanded over approximately a fifth of their length at their inner ends, indicated at 55. The embodiment shown in Fig. 3 is a fully flexible assembly 41 comprising a centre roller 41 flanked by tapered wing rollers 42, 43 connected to side ropes 11, 12 by link assemblies 45, 46 and hanger members 47, 47a. When the belt 36 is detrained to the right, as shown, wing roller 43 is dragged forward, pivot 48 allowing this, whereby the whole assembly 40 is swung counter-clockwise, introducing a centring effect on the belt. As the belt 36 moves back to a position substantially central the assembly 40 moves back to a position at right-angles to the direction of belt travel.
