Abstract:
This invention relates to locking mechanism for a weighing scale capable of weighing flat articles at a high rate and with a high degree of accuracy. The locking mechanism of the instant invention is applicable to a vibrating tray type scale which requires a mechanism for stabilizing the base of the scale during periods when articles are being conveyed onto and off the tray of the scale. An electromagnetic locking mechanism has been conceived that provides advantageous for a vibrating tray scale. These advantages are simple construction, low cost, self compensating and zero force requirement. With a such locking mechanism, the vibrating tray scale functions more accurately and rapidly.
