RICHARD UEEN, or HoUGHToN, MICHIGAN.
ROLLING-Mlm..
SPECIFICATION forming part of LettersPatent No. 274,856, dated March 27, 1883.
' Application led December 8, 1882. (No model.)
To all whom it may concern Be it known that I, RICHARD UREN, of Houghton, in the county of Houghton and State of Michigan, have invented certain new and useful Improvements in Rolling-Mills;
land I do hereby declare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawv ing, which forms part of this specification.
` pillow-blocks Z My invention has relation to rolling mills; and it consists in the means, as .hereinafter more fuily described and claimed, for supporting the bottom roll `at each end of a set of rolls, whereby I prevent breakage of the roll or its support incase of any sudden strain upon the rolls by neglecting to properly ease the adj Listing-screw, or4 from other causes.
In the accompanying drawing I have shown a vertical elevation, partly in section, of one of the sides of their-ame or so-called cheeks of `a rolling-mill equipped with my improve-V ment. Y
A is the frame;'B, the adjusting screw of the upper roll; R and R, the rolls; r and a', their respective or bearings of the respective roll-journals. The pillow-block G of the bottom roll rests, .at each end of the frame, upon the head H ofia plunger or piston, P, said head being of a shape and area corresponding to or approximating that of the pillowblock C. The plunger P works in acylinder or barin the drawing.)
rel, E, in the lower part of the frame, which has an inlet-pipe, D, communicating with a small but powerful force-pump, G, of any approved construction. This pump is kept in continuous operation while the mill is working, and pumps water, oil, or other liquid into the cylinder E, the pump connecting with a suita bly-located tank or reservoir, (not shown Another pipe, d, connects cylinder E with a safety-valve, F, of any desired construction, the weight on which (as usual in safety-valves) may `be adjusted to regulate the fluid-pressure within cylinder E. The latter has an annular groove or channel, e, which is filled with packing, thus forming a stiflng-box for plunger P and preventing waste of the duid through the top of the cylinder. Upon the cheeks A are stops f, which may be either fixed or adjustable, for the pur- A pose of `regulating the positionA+ of the lower V i ,f
`that may occur.l Excess of pressure beyond journals; and Cjand (l, the` roll and its bearings relative to the upper roll irrespective of the iuidpressure to which plunger P is subjected. In otherwords, the bottom roll cannot rise higher than to the stopsff, which indicate its proper working position; but it will be maintained in this position by the hydraulic pressure caused by the steady inflow of uid 4into cylinder E, which compensates for any waste or leakage agiven point brings the' safety-valve F into operation, and the fluid will escape through it, and maybe conducted back through suitable tubing to the tank or reservoir connecting with the force-pump, from Which it is again fet-l to the cylinder, thus constituting a regular circuit. This of course applies equally well whether the excess of pressure is under the plunger or above it, caused by sudden Vstrain or pressure onA the bottom roll. In the latter case the roll will yield to the strain by depressing plunger P, forcing out a portion of the liquid through the safety-valve;` but the moment the strain or excess of pressure ceases to operate, the roll will resume its former position by the injection of liquid into the cylinder through the force-pump, which, as I have stated, is iu continuous operation during the Working of the mill. The point at which the roll will yield is regulated by the adjustment of the safety-valve. 8
Havingthus described my invention, I claim and desire to secure byLetters Patent of the United States- 1 `1. In a rolling-mill, a bottom roll having its bearings supported upon the Aplunger or platen of a hydrostatic press connecting with a force-pump and safety-valve adapted to regulate the strain or pressure upon the roll at `which it will yield,'substantially as and for the purpose show n and set forth.
2. The combination, in a rolling-mill, of the bottom roll and its pillow-blocks or bearings, the hydrostatic press, the force-pum p, and the safety-valve, constructed and arranged to operate substantially as and for the purpose shown and set forth.
In testimony that I claim the foregoing as my own I have hereunto aftixed my signature in presence of two witnesses.
