PROVISIONAL SPECIFICATION left by the said William Robert Lake at
the Office of the Commissioners of Patents on the 22nd July 1880.

METAL." [A communication from abroad by Wilhelm Wenstrom, of Orebro,
Sweden.]
This Invention relates to improvements in rolling mills, or apparatus for rolling
iron in bars, plates, or other forms.
Mills constructed according to this Invention differ from the universal rolling
mills heretofore in use, in that the compression is effected by my apparatus on all
four sides at one point of the bar, and for this reason the rolling will be as
favorable for the iron as when rolling in grooves; and my Invention possesses
the advantage that different widths and thicknesses of metal may be rolled
without shifting rolls. When rolling ingots and rough bars the edge compression
is not however important.
In carrying the said Invention into practice, an apparatus or mill for rolling flat
bars and girder plates is constructed as follows, that is to say:-I provide an upper
and a lower vertical roll, the length of which is made according to the work
intended to be performed. The upper roll is mounted in bearings on a rising and
falling cross-head, which is adjusted by head screws, gear-wheels, and a hand-wheel.
The lower roll always maintains the same level, and has its bearings on a frame
sliding in grooves formed on the bed, and is moved laterally by means of a feed
screw, bevel gearing, and a hand-wheel. Two horizontal edge rolls are also
provided. The upper one does not move vertically, but the lower one rises and
falls with the upper vertical roller, and is also capable of a lateral adjustment to
CDC17

effected by two horizontal guides sliding upon one of the rising and falling cross
heads, and two vertical guides for the sliding frame. The cross-head carrying the
upper vertical roll is kept tight against the head screws by braces. The elevation
of the upper vertical roll determines the thickness of the bar or plate, and the
lateral adjustment of the lower vertical roll determines the width of the bar or
other piece of metal. Sliding rules moved by a worm on each of the hand wheel
shafts indicate the dimensions of the rolled piece.
The said apparatus or mill may be driven by long coupling spindles allowing
the adjustment of the rolls, but I prefer to employ four pinions, two of which are
constantly in one position, but the one on the shaft of the upper roll is capable of
being raised and lowered without material inconvenience, and the one on the shaft
of the lower roll is capable of being easily moved along in broad cogs or teeth.
The horizontal edge rolls are moved by friction against the rolled bar.
The bar or plate is guided to and from the rolling point by conductors. When
rolling in one direction one conductor does not require to touch the roll. These
conductors are fixed on the sliding frame, and move laterally with the lower roll;
they are furnished with a projecting flange on the side towards the movable edge
roll, but towards the stationary edge roll the bar or plate is guided by a fixed
guide. If relievers for the upper roll are required, sucli relievers are fixed to the
upper cross head, and therefore will be raised or lowered with the said roll.
For rolling ingots, the edge rolls are dispensed with, and instead thereof the
vertical rolls are furnished with a collar on opposite ends for conducting and
confining the ingot and preventing side spreading of the metal. Otherwise the
apparatus for rolling ingots will be constructed as above described.
My improved rolling mill or apparatus may be run continually in one direction
or reversed, as may be desired.
The apparatus for rolling rough bars is made much the same as the one for
rolling ingots, but I employ three rolls, the upper and the lower of which are
adjusted vertically, whilst the central one is movable laterally, and thus the width
of the bar is contined. This mill or apparatus will roll in both directions without
reversing motion.

WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, and Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN MACHINERY FOR ROLLING
METAL" A communication from abroad by Wilhelm Wenstrom, of Orebro, Sweden.
This Invention relates to improvements in rolling mills, or apparatus for rolling
iron into bars, plates, or other forms.
Mills constructed according to this Invention differ from the rolling mills
heretofore in use, in that the compression is effected by my apparatus on all four
sides, and at directly opposite points of the welded bar or other piece at the same
time, and for this reason the rolling will be as favorable for the iron as when
rolling in grooves; and iny Invention possesses the advantage that different widths
and thicknesses of metal may be rolled without changing the rolls. When rolling
ingots and rough bars the edge compression is not however important.
My improved machinery for rolling flat bars and girder-plates is illustrated in
Figures 1, 2, and 3 of the Drawings, in which,
Figure 1 is a vertical section of the said machinery, and
Figure 2 is an end view of the same partly in section on a plane at right angles
to that of Figure 1.
Figure 3 is a horizontal section of the said machinery.
In these Figures A represents the upper and B the lower roll, the length or
width of the bodies or faces of which is suited to the work intended to be per-
formed. The upper roll is mounted in bearings on a vertically movable cross-
head E, which may be adjusted by the screws F, the gear-wheels G, and a hand-
wheel H. The lower roll B always maintains the same level, and has its bearings
on the frame I, which slides in grooves formed in the bed J, and is moved laterally
by means of a feed-screw K, the bevel gearing L, and the hand-wheel M. Cand
D represent two edge-rolls, the position of one of which C remains unchanged, its
support or bearing being bolted to the standards. The other edge-roll D however
is adapted to follow the upper roll in its vertical adjustment, and the lower roll B
in its lateral adjustment. This double motion is effected by providing the bearing
support O of the roll D with horizontal guides P sliding upon the cross-head E, and
by two vertical guides Q upon the sliding frane I. The cross-head carrying the
upper roll is kept tight against the head-screws by braces R. The elevation of the
upper roll determines the thickness of the bar or plate, and the lateral adjustment.
of the lower roll determines the width of the bar or other piece of metal. Sliding
scales or rules moved by a worm on each of the hand-wheel-shafts indicate the
dimensions of the rolled piece.
The said apparatus or mill may be driven by long coupling spindles allowing the
adjustment of the rolls, but I prefer to employ four driving pinions, two of which,
S and T, are constantly in one position. The pinion U however of the upper roll
is capable of being raised and lowered without material inconvenience, and the
pinion V on the lower roll is capable of being easily moved lengthwise without
becoming disengaged from the long or broad teeth or cogs of the gear-wheel T.
The edge-rolls C and D are revolved by friction against the bar being rolled.
The bar or plate is guided to and from the point at which it is acted upon by
the rolls by conductors W and X. When rolling in one direction only the con-
ductor W does not require to touch the roll. These conductors are fixed on the
sliding frame I, and move laterally with the lower roll to suit the different widths
of metal to be rolled. The conductor W is furnished with a projecting flange Y on
the side adjacent to the movable edge-roll D; on the side adjacent to the stationary
edge-roll C the bar or plate is guided by a fixed guide Z. If relievers for the
upper roll are required, such relievers are fixed to the cross-head E, as at A°, and
therefore will be raised or lowered with the said roll.

page_text: Figure 4 is an elevation of the rolls to be employed in an apparatus or machine
for rolling ingots.
A is the upper roll, which is capable of vertical adjustment in a similar manner
to the roll A above described, and B is the lower roll, which may be adjusted
laterally. In this machine I dispense with the edge-rolls, and in the place thereof
I furnish each of the rolls A, B, with a collar, as shewn at A1, B1, on opposite ends.
These collars conduct and confine the ingot, and prevent lateral spreading of the
metal or the formation of oblique corners. In other respects the apparatus for
rolling ingots is constructed in a similar manner to that shewn in Figures 1, 2,
and 3 of the Drawings.
In applying my improvements to a machine or apparatus for rolling piled iron, I
provide the vertically and laterally adjustable rolls A, B, with two collars A', A¹,
B', B', as shewn in elevation in Figure 5, these collars being of such a distance
apart as to suit the width of the pile. In such rolling, the rolls, during the first
and second passages of the pile, are retained in the position shewn in full lines,
that is to say, with their collars directly above each other. When the iron is in
proper condition, and is stiff enough to be reduced in size by rolling, the said rolls
are adjusted in the same manner as those above described, and the metal is guided
by two of the collars only at opposite corners of such metal, as shewn by the
dotted lines in the same Figure.
My improved rolling mill or apparatus may be run continuously in one direction
or reversed, as may be desired.
The apparatus for rolling rough bars is constructed in much the same manner as
the one for rolling ingots, with the exception that I employ three rolls, as shewn
in elevation in Figure 6. The upper and the lower rolls are adjustable vertically,
whilst the central roll is moveable laterally to determine the width of the bar.
This mill or apparatus will roll in both directions without reversing gear.
Having thus fully described the said Invention, as communicated to me by my
foreign correspondent, and the manner of performing the same, I wish it understood
that I claim,-
First. In a machine for rolling welded bars or plates the rolls so arranged as to
act on the same on all four sides and at directly opposite points thereof at the
same time, substantially as above set forth.
Second. In a machine for rolling ingots or rough bars the rolls provided with a
collar on one end to confine and determine the width of the said ingots or bars,
substantially as above described with reference to the Drawings.
Third. In the said machine the employment of rolls each provided with two
collars, as and for the purposes specified.
Fourth. In a machine for rolling metal a roll adapted to be moved laterally to
enable bars or plates of different width to be rolled, substantially as above described.
Fifth. In a machine for rolling metal the edge-roll adapted to follow the
movements of the upper and lower rolls by the combination therewith of horizontal
and vertical guides, substantially as above set forth and for the purpose specified.
Sixth. In a machine for rolling metal the bar conductors or guides, constructed
and arranged substantially as above set forth and for the purpose specified.
Seventh. In a machine for rolling metals the combination with the vertically
and laterally adjustable rolls of the driving pinions, substantially as above set
forth and for the purposes specified.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Twenty first day of January, in the year of our Lord
One thousand eight hundred and eighty one.
