Claims
- 1. Machine for filling bags with a liquid and sealing them, comprising:
- liquid proportioning means;
- a pair of jaws adapted to open substantially along a given direction, said pair of jaws having suction means for holding the upper lips of a bag by partial vacuum, said pair of jaws being mounted beneath said liquid proportioning means;
- a toggle joint comprising two pivotally interconnected links and an actuating member connected to said joint at said pivotal interconnection, each said link having an end remote from said pivotal interconnection and said actuating member being displaceable in a direction substantially perpendicular to said given direction; at least one of said remote ends being pivotally connected to one of said pair of jaws; said pair of jaws being closed when said links are extended relative to one another, and open when said links are more nearly collapsed relative to one another; whereby displacement of said actuating member in said perpendicular direction at a constant rate will open said closed jaws at a progressively increasing rate;
- and a manually operable pedal for pulling said actuating member in a direction to open said jaws.
- 2. Machine according to claim 1, and a pair of heat sealing jaws disposed between said liquid proportioning means and said pair of jaws having suction means, said pair of heat-sealing jaws being closable independently of said pair of jaws having suction means.
