The nature of my invention consists in hanging the bed stone in the frame in such a way and manner as to give it a free and easy vibration or balance. Also in the manner of connecting the bail or carrier to the spindle, and also in the manner of constructing the step or oil cups in such a way as to prevent the points heating or running dry.

To enable others skilled in the art to make and use my invention I will proceed to describe its construct-ion and operation.

I construct my mill frames in any of the known forms and apply thereto the manner of hanging or securing the stones as herein set forth, also the pecliar form or arrangement of step or oil chamber.

M is a slot or groove cut on the outer edge of bush I-l through which the oil can pass from cup I to chamber L and point I.

N is the frame in which the bed stone 0 is hung.

P is a rim with two opposite points or bearings (1 g secured to the outer surface of rim projecting outward and hangs in frame N so as to balance or vibrate on the same.
