683,606. Opener trains-feed controlling arrangements. AKT.-GES., J. J. RIETER & CIE. April 28, 1948 [August 26,1947], No. 11680/48. Class 120(i) [Also in Group XXXV] An opener train of textile machinery having a quantity-regulating system which operates in accordance with the principle, that, depending upon the material requirements of one machine, the feeding device of the preceding machine or group of machines is put into operation or is stopped, is characterized in that all'moving and operating parts of the opener train which are subject to cause operational faults and blockages have supervisory means which act on the said quantityregulating system of the opener train in such a manner that in the event of any operational fault or blockage at one of the said supervised parts of the opener train, all the supply arrangements of the opener train are sopped. As shown, diagrammatically, A is a bale-opener and B is a hopper feeder. The lattice 1 conducts material to be loosened to the bale opener A after which the material is fed through a duct 4 over a revolving suction cage 5, the lower portion of which is covered by an inner shield 6 so that the material in this zone drops on to the lattice 7 which feeds it to the spiked lattice 8 of hopper feeder B. The lattice 1 is driven by a rope drive 13 from the upper shaft 12 of the spiked lattice 2. The shaft 12 has a clutch portion 14 keyed to it which clutch portion may be put into engagement with an axially displaceable clutch portion 15 controlled by a bell crank lever 18 pivoted at 17 and normally held in a position, in which the clutch is disengaged, by a spring 19. The shaft 12 is driven, when clutch 14, 15 engages, through gears 16 and 20 from a shaft 21 having a pulley 22 connected by a rope drive to a motor 23. To engage the clutch the end of the bell crank lever remote from the clutch is connected to an electromagnet 25 in an electrical line 26 in which is a battery 27. The line 26 represents a regulating circuit including two switches 28 and 29. Switch 28 is connected by a link 30 to a spade-like member 31 in the hopper feeder B. Should too much material accumulate in the hopper feeder B, switch 28 is opened de-energizing the electromagnet 25 thus disengaging the clutch and stopping the feed of bale opener A. Electrical line 32 represents a supervisory circuit and includes an electromagnet 33, the armature 34 of which is connected to the switch 29 of line 26. A plurality of switches 35, 36 and 37 are included in the supervisory circuit 32, each being connected to some point of possible operational fault or blockage. Thus switch 35 is linked to an arm 39 pivoted at 40 and hugging a portion of cage 5, if a lap forms on the cage, switch 35 is broken. Similarly switches 36 and 37 are connected to thermal switches 43 and 47 in the supply lines of motors 45 and 23 and are opened in the event of the respective motors overheating. If one of the switches 35, 36 or 37 is opened the electromagnet 33 is de-energized, switch 29 is opened, electromagnet 25 is de-energized, clutch 14, 15 is dis-engaged and the drive to shaft 12 interrupted. A signal lamp 49 may be provided in the circuit 32. Instead of the electric supervisory and regulating circuits electro-pneumatic means may be used. Other regulating and supervisory circuits may be added as required.
