UNITED STATES PATENT Orrioa.
HARVEY T. ASHWORTH, OF OHATHAM, VIRGINIA. p
IMPROVEMENT IN MILL-SPINDLE BUSHES.
Specification forming part of Letters Patent No. 90,463, dated May 8,. 1877 application filed March 12, 1877.
To all whom it may concern Be it known that I, HARV Y T. ASHWORTH, of Ghatham, in the county of Pittsylvania and State of Virginia, have invented a new and Improved Millstone-Bush, of which the following is a specification:
In the accompanying drawing, Figure 1 represents a vertical central section of my improved self-lubricating millstone-bush on line y y, Fig. 2; and Fig. 2, a horizontal section of the same on line 00 :10, Fig. 1.
Similar letters of reference indicatecorresponding parts.
The invention relates to an improved selflubricating millstone-bush that keeps the spindle supplied with the necessary grease for a considerable length of time, prevents the entrance of dust and other impurities to the journal-bearing, and provides in an effective manner for the expansion or contraction of the spindle.
The invention'consists of a bush for the eye of the bed-stone, which is made of a block of hard wood or metal, and recessed for the reception of the cushioned journal-blocks or fob lowers, that are recessed near the upper end, and filled with a suitable lubricating mixture. The top of the journal-block is tightly closed by a rubber cap fitting tightly around the spindle.
In the drawing, A represents the spindle that passes through the bed-stone, and revolves in the bush B, of hard wood or metal, that is secured in the eye of the same.
The interior of the bush is mortised for the reception of the radially sliding and guided journal-blocks or followers B that constitute the bearing for the spindle, and are cut with the grain of the wood at right angles to the spindle.
Each journal-block'B has a recess, 0, cut in the upper inside part, said recesses opening toward the spindle, and being filled with a suitable lubricating mixture-as, for instance, beeswax and tallow-which is poured in a melted state, through communicating top holes a of the followers B into the recesses G. The
cushioning-pieces d, which act as springs to,
keep the blocks close to the spindle, and give way in case of expansion of the spindle by heat, insuring thereby equal wearing 'thro ughout the length of the box. For the purpose of adjustment, after wearing by use, one. or more strips, 6, of tin or other material, are placed behind each rubber cushion.
The journ al-blocks B are supported on radial blocks B that are inserted into holes mortised at right angles to each other, in the same manner as the mortises of the blocks, but e xtended through the entire thickness of the bush B.
An indie-rubber cap, D, is attached, by a metallic binding-rim g, f, and fastening-screws, to the top of the bush, and is fitted tightly around the spindle, to prevent any dust or other impurities from entering the journalbox.
The millstonebush is of cheapand simple construction, and may be run for a considerable length of time without refilling the Inbricating recesses, being self lubricating and adjusting, and protected against the entrance of dust to the point of contact of the spindle with bush.
Having thus described my invention, I claim as new and desire to secure by Letters Patcut- The combination of the millstone-bush B, having radial supporting-blocks B and the followers 13, having rubber cushions d, with the spindle inclosed by the elastic dust-cap described, substantially as shown and set forth. I
HARVEY THOMAS ASHWORTH.
