Title: Cleaning machine cylinder balancing apparatus
IPC: D06F34/08
Filed: 1947-08-09
Abstract: 663,829. Testing balance of rotating bodies. KAHN, L. M. Aug. 9, 1947 [May 31,1946], No. 22183/47. Class 106 (ii). [Also in Group II] The basket 15, Fig. 1, of a spin-drying washing-machine is balanced, when spinning, by the introduction of water to one or other of three spaced chambers 31, 32 on the basket. Water from a pipe 35 is admitted selectively, by means of valves 56, 57, 58, to concentric grooves in the end face of the trunnion 21 which communicate with the chambers. The valves 56, 57, 58 are operated by solenoids 59, 60, 61 in circuits of a device responsive to out-of-balance vibrations. Shaft vibrations are communicated to a part 69, 70 carrying a coil 68 within the field of a magnet 65. The alternating voltage generated in the coil, after amplification, is applied to the grids of three thyratron valves 62, 63, 64, Fig. 4. The three plates 65, 66, 67 are connected in turn to a power supply by means of a commutator 82 rotating with the basket and current flows through the valve which is energized at the time when the grid voltage exceeds the firing voltage. This current passes through the associated solenoid 59, 60 or 61 and its water valve 56, 57 or 58 is lifted. The thermionic valve is energized for less than a third of a basket revolution, but the current is maintained in the solenoid by means of a condenser 95, 96 or 97. Two valves will operate if the grid voltage phase is between those of two plate energizations. In an alternative arrangement, Fig. 9, the three plates are permanently connected to the power supply and the grids are connected in turn, by the commutator 108, with the circuit of the vibration-responsive device. Each grid circuit is provided with a maintaining condenser 123, 124, 125. To prevent hunting, the opening of any of the valves 56, 57, 58 moves a switch by which the grid bias on the thyratron valves is reduced. The water valves could be operated by means of a Selsyn motor, one winding of which is connected to the device responsive to the shaft vibrations and the other to the commutator. The invention may be applied to effect balancing by the release of liquid from normally filled chambers.
