IMPROVEMENT IN MILLSIONE-BUSHES.
'IO ALL WHOM IT MAY CONGERN:
Be it known that I, C. CUSTER, of Philadelphia, in thc county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Millstone-Bush; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and user the same, reference-being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a transverse section of my improved millstonediush, taken in the line c: @,ig. 3.
Figure 2, a bottom view of the same.
Figure 3, a diagonal vertical section, taken in the line g/ y, iig. 2, with Ythe spindle in the box.
- Figure 4, a vertical cross-section, taken in the line 'w w, fig. 2.
Similar letters of reference indicate lik-e parts.
This invention relates to improvements in the construction of boxes f or bushing the spindles of millstones, whereby a spindle may be adjusted with perfect accuracy by means of thumb-screws, and wedges operating on loose wedges lying against the spindle, which wedges are made of iron, brass, or wood, or may be faced with Babbit metal, leather, or any other anti-friction material. Lubrication is also fully provided forhy chambers to hold oil, made in the bushing-wedges, and all extraneous substances are excluded from the bushing by a chamber containing packing-yarn on the top of the bush around the spindle, as hereinafter more particularly described.
A represents a mill-spindle, and B an external bushing-box or shell, to be set in the eye of the bed-stone -of a pair of millstones. The bushing consists of four quarter segments C C', which are formed of iron, brass, or wood in wedge-shape, to be placed with their points downwards, and having their faces tted exactly to the spindle. They may be faced, if desired, with Babbit metal, leather, or any other anti-friction material. In the upper part or head of the bushing-wedges C C are chambers aa, for containing oil which flows through holes at ythe bottom directly against the neck of the spindle to lubricate it. On the under side of the main box B are secured four radial slides Z b, that are held in placeby screws and nuts, for the purpose of supporting the bushing-wedges C C, when they are put in the box B for adjustment to the spindle. In each corner of the box or shell B are formed radial recesses, as wide as the segment-bushing wedges C C, for receiving corresponding wedges D D, that lie in reverse position at their'back, and are drawn up to bear against the bushing-wedges, and drawthem in place to adjust them to the spindle. This is done by means ,of adjusting-screws c c, which run through the binding-wedges D D from the top to the bottom of the box B, as shown clearly in g. 3. These adjusting-screws c ca-re suspended by their heads cl d, within the upper part. of the box B, in suoli manner that they can slide nearer to' or farther from the spindle, and they lit within vertical slots in the large or bottom ends of the binding-wedges D D, to admit of their adjusting radial movement nearer to or further from the spindle. The screws c c project through the lower ends of the binding-wedges D D, and are provided with wing-nuts e e, for bearing them up against the bushing-wedges C C, and thus adjust the spindle exactly as desired. On the top of the box B is placed a chamber, g, which is to be lled with cotton, yarn, or any other suitable packing- -to prevent the admission of dust or any extraneous substances, and the chambery is covered with a cap or follower, L, which lits around the spindle, and is screwed upon the top ofthe box B.
Having thus described my invention, I claim as new, and desire to secure by Letters Patent- 1. The millstone-bushing, constructed as described', consisting of the segmental wedges G, having chambers a in the upper ends, placed in the four corners of the shell B, with their concave faces fitting against the spindle, and supported by the adjustable radial plates In, upon the under side of said shell, and adjusted by the reverse wedges D fitting against the wedges C in the same radial recesses, and adjusted fromthe under side, by means of the screw-bolts c and nuts e, as herein described for the purpose specified.
2. The combination and arrangement of the hollow wedges C, reverse wedges D, radial slidesb, screw-bolts c, shell B, follower h, and chamber g, as herein described for the purpose specified.
3. The radial slotted slides b, in combination with the hollow segmental wedges C, when such slides support said wedges by passing across their inner corners, asv herein 'set forth for the purpose specified.
