Abstract: An insulated keyless chuck for drills and the like having threadedly interconnected plastic spindle and collet members providing therebetween an internal chamber for a circumferential array of waferlike chucking elements each with inwardly open hook formations at the outer ends thereof for permissive sliding interengagement with corresponding slots at the outer edges of a pair of cone-shaped retainers one of which is carried by the collet member and the other by the spindle member such that relative axial movement of the collet and spindle members toward or away from each other will effect a radial component of relative movement of the chucking elements toward or away from one another.

Abstract: A liquid level indicator and hydrometer for use in determining the liquid level of a fluctuating liquid as well as determining simultaneously the specific gravity thereof. The device contemplates a hollow body operatively mounted on the lower extremity of a light-transmitting liquid level indicator with a plurality of colored float means having differing specific gravities which are optically visible through the lighttransmitting liquid level indicator simultaneously with the readout of the liquid level.
