'UNITED STATES PATENT OFFICE.
CHARLES H. PERKINS, OF PROVIDENCE, RHODE ISLAND.
IMPROVEMENT IN ROLLING-MILLS.
Specification forming part of Letters Patent No. 128,422, dated June 25, 1872.
To allpersons to whom these presents may come:
Be it known that I, CHARLES H. PERKINS, of the city and county of Providence, of the State of Rhode Island, have invented a new and useful Improvement in Rolling-l\/Iills,7 or machinery for rolling iron or other metal; and do hereby declare the saine to be fully described in the following specification and represented in the accompanying drawing, of which- Figure 1 is a front elevation 5 Fig. 2, an end View; and Fig. 3, a vertical and transverse section, of three pairs of reducing-rolls,with their supports and operative mechanism, with my invention applied to such rolls, whichare of the kind used for rolling iron into iiat bars, either square or rectangular, in transverse section,the upper roll of each pair being extended within its fellow-roll, in the manner as shown.
In rolling a metal bar by rolls of the kind dedescribed and shownthere will be what are termed ns raisedv on its upper surface at its opposite edges, such being due to the pressure on the metal between the continuous vertical edges of the reducing parts of the rolls. To reverse or turn the bar the bottom side up While passing from one pair of rolls to the next pair, so that what was first the upper or in side of the bar in passing between the first pair may become the lower side of it in passing between the next pair, is the obj ect of my invention, the same being to effect the removal of the said tins77 from the bar.
In carrying out my invention I combine with each pair of the reducing-rolls and the next succeeding pair a guide passage or tube in the form of a semicircular arc, or thereabout. The said passage or tube I term the reversingguide,7 it being hereinafter more particularly explained. I
In the drawing, A denotesthe frame for supporting the several pairs B B C C D D of rolls, they being arranged relatively to one another and provided with suitable operative mechanism, all as represented. The reversingguides are exhibited at E E', one being extended from the bite of the lowermost pair of rolls B B to that ofthe next rolls C C. The other l.reversing-guide Ef, arranged on the opposite side of the machine, extends from the bite of the rolls C C to that of the rolls D D', all being as represented.
Figs. 4 and 5 are views of the two sections or parts of each of the inside reversing-guides. Fig. 6 is a transverse section of such two parts taken through their supports. One of theparts is fastened directly to the frame and the other is secured to the fellow part by keys la lc going through studs l Z projected from the supportinging-ears m m of the stationary part, and also through those a n of the movable part, all being as shown in the drawing.
When two reversingguides are arranged with three pairs of -rolls in the manner as shown they form a serpentine passage leading from the irst to the second pair and from the latter' to the third pair, whereby a bar of iron will be guided from the first pair to the second and turned over in the mean time, and next be guided from the second pair of rolls to the third pair and be turned over while passing from the said second t0 the said third pair.
The arrangemenaof the three pairs of rolls and thetwo reversing-guides saves the employment of a fourth pair of rolls, which would or might otherwise be necessary provided the two guides were disposed in separate frames with a pair of rolls to each.
I claim as my invention- The combination and arrangement of the two reversing-guides E E' with the three pairs of rolls B B', C C, and D'D, all being to 0perate substantially in manner as described.
- CHARLES H. PERKINS.
