REUBEN TfJENNINGS, SR., OF RICHMOND, VIRGINIA, ASSIGN OR OF yONE-HALF HIS RIGHT TO JOHN B. GRENSHAW.
IMPROVEMENT IN MILL-BUSHES.
Specification forming part of Letters Patent N0. l90,0118, dated April 24, 1877,; application iiled March 26, 1877. A
construction of a frame for holding mill-bush-v ing, and the meansof moving said bushing, the peculiarities ot' which will be hereinafter more fully described.
In the accompanying drawings, making part of this specification, Figure l represents a vertical section, and Fig. 2 a cross section, of my invention.
In the gures, A represents a square metallie case, which surrounds the bushing. In the four corners' of this case are four square boxes, B B. These may be made solid, but are made in box form, thus making the case less expensive and lighter. Between the boxes B B are placed the wooden bushingblocks C O, which have their faces concave, to fit the shape of the spindle I. The case immediately back of the blocks C O is either made wedge-shaped or is provided with stationary wedges, as seen at D D. e e repre sent nuts, which are inserted in the blocks O C. E E are screw-bolts, which pass through flanges' J J of the case, then through the bottom of the ease, and then into thenuts e e in the blocks. F F represent sleeves, which surround the bolts E E between the bottom K and the anges J J, being secured by pins a c to said bolts. G represents a large grease or oil box upon the top of the frame, and H represents a close cover to the same. I is the spindle, which stands between the blocks O O.
The object of the screw-bolts is to keep the blocks in proper position, and to draw them down as they wear, so that they will t snugly against the spindle. The blocks may be made slightly tapering on their backs, to lit the taper of the wedges D.
By this arrangement the blocks can be raised or lowered by means of the bolts, and the spindle bushed and regulated while the mill is in operation. Suflicient grease may be placed in the chamber G to last for a long while.
Having thus fully described my invention, what I claim isl. The bolts E E, and sleeves F F secured to same, in combination with the blocks C C and their nuts e e, as and for the purpose set forth.
