ABSTRACT:
Agitator for the stirring of liquids which are enclosed in vessels the inner space of which is accessible through a hole in the wall of the vessel and of a small dimension compared to the dimension of the vessel, the agitator comprising an actuating organ and a turnable shaft for the rotation of the organ, which organ has the form of a screw with a larger diameter than said hole. The thread of the screw is formed of a coiled stripe the width of which is smaller than the width of the largest cross section of the hole and with a pitch which is so large compared to the thickness of the stripe and the height of the walls of said hole that, when the stripe forming the thread is inserted into the hole with a portion positioned on the one side of the center axis of the screw, the portions forming the thread on the opposite side of the axis will find room outside the projection of the hole at both sides of the wall through which the hole extends. The screw can in this position be screwed through the hole until the shaft is placed within the hole.
