PROVISIONAL SPECIFICATION.
Improved Universal Mill for Rolling Iron and Steel Plates,
Bars, and the like.
SAMUEL ADAMS 12 Banks Street Middlesbrough-on-Tees Rolling Mill Manager. I
do hereby declare the nature of this Invention to be as follows:
By means of Vertical rolls Side guides Wedges and Screws attached and adjusted
substantially in the way as now described for the purpose of rolling the edges of
plates, bars or the like straight and sound and thus avoid rough and unsound edges
which have hitherto bad to be sheared or dressed of.
I am aware that the use of Vertical rolls for the above purpose is not new.
I attach and adjust the Vertical rolls upon Brackets or riders each set of which is
surported and adjusted by four Screwed Shafts such Shafts having left and right handed
Screw threads for the purpose of moving or adjusting the Vertical rolls horizontaly and
simultanously either inward or outward the Side Guides or Cheeks are set adjusted
and moved simultanously, substancially in the same way namely by the use of Screwed
Shafts having on them left and right hand threads.
I also use Wedges applied Vertically and horizontaly adjusted and held in position
by Set Nuts and Screws for the purpose of setting the main and horizontal train rolls
and to act upon the top rider. Also a short additional regulating Screw fitted into the
Braker or rider and between the Main Screw and rider for the purpose of adjusting.
the draught upon the flat sides of the plates or bars and the like when required.

Improved Universal Mill for Rolling Iron and Steel Plates,
Bars, and the like.
I, SAMUEL ADAMS of Seaton Carew, West Hartlepool, Rolling Mill Manager
do hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement :-
The object of my Invention is to adapt to a rolling mill, a device for producing
sound and parallel edges upon the plate or bar of metal, during the process of rolling ;
thus obviating the necessity for any subsequent trimming, or shearing operation upon
said plates or bars. And further to apply certain regulating devices, to be hereinafter
fully described, to said rolling mills, and the frames thereof; for the purpose of ensuring
great accuracy, as also facilitating the process of adjustment. Said devices may be
applied to existing mills, of the ordinary construction, or may be, if desired, comprised
in a mill of special design.
In order that my Invention may be the better understood, I have appended the
accompanying four sheets of drawings, in which Fig. 1 represents a front elevation of
a rolling mill, consisting of two horizontal rollers, Fig. 2 is a plan and Fig. 3 is
an end elevation of the same-Fig. 4 is a horizontal section of the adjusting device,
and Fig. 5 a transverse section of same. Fig. 6 is an end elevation of a rolling
mill, consisting of three horizontal rollers, commonly called a three high" mill,
Similar letters of reference indicate corresponding parts, throughout the several
views.
to
In carrying out the improvements, according to my Invention, I employ vertical
rollers d, d, Figs. 1, 2 and 3 driven by the horizontal shaft e and the mitre wheels f',
which transmits motion to the vertical shafts g g. Said shafts g g, are supported by
suitable bearings, bracketed to the metal nuts, or female screw blocks bbbb, which
are supported by, and engage with the threads of right and left handed screws c c,
allow of equal adjustment of the vertical rolls d d, by means of the pinions hh, the
teeth of which engage with the teeth of the spur wheel i (Sheets 1 and 2). Said
spur wheel, is freely suspended upon a stud, rigidly attached to the main frame A A.
By means of a handle j, or equivalent, the adjustment of the vertical rolls d d, is
effected with ease. The side guards B. B. B. B Fig. 2 are bracketed to metal nuts, or
female screw blocks, and are supported by the horizontal screws kkkk, to the ends
of which, are attached the pinions 1. 1. 1. 1, gearing with the spur wheels m m, which
latter are controlled by means of suitable handles n. n.

page_text: The main vertical screws D, D, which are controlled by the drums a a, or equivalent
device, hear upon a short regulating screw G, fitted into the breaker U. Said
breaker U is cast upon, or secured to the carriage bearing, or top rider K, of the top
roll L.
Said regulating screw G, is provided with holes around its outer circumference, so
that it may readily be adjusted, by means of a pointed bar, or the adjustment of said
screw G, may be effected in any other suitable inanner.
The carriage bearing or top rider K, of the upper roll L, may be horizontally adjusted,
so as to bring the top roll L, in a suitably parallel, or other desired position, relatively
to that of the lower roll M, by means of the wedges E, E, provided as shewn with
suitable lugs, through which pass screw studs o o fitted with nuts, or other suitable
tightening device.
By means of the screw G, and the screw wedges E, E, it will be seen that the top
rider K may be adjusted vertically, and horizontally, with great accuracy and ease.
The carriage bearing of the intermediate roll R, Fig. 6, (shewn also in the detached
sectional views, Figures 4 and 5,) is fitted with wedges H H H H, provided with
screws which pass through suitable slots, formed in the Bange of the tapered liner J. J
and secured by nuts I. The whole carriage bearing is enclosed as will be seen on
reference more particularly to Figure 5 by a double casting PP, the two parts of which,
are attached by screw studs to the usual enclosed brasses, slots being provided to allow
of horizontal adjustment.
By means of the arrangement last above described, I am enabled to effect the
adjustment of the intermediate roll, horizontally with the same ease and facility, as
the upper or lower rolls, said intermediate roll, being situated in such a position, that
the vertical adjusting screw nuts o o before referred to and described, would not be
applicable for effecting said adjustment.
"
In using the device or contrivance according to my Invention, I can by means of
the right and left handed screws kkkk, adjust the side guards, or guide cheeks B. B B. B,
to any desired degree, and, in rolling the plates or bars of metal, the vertical rolls dá
may be adjusted to "form a sound edge upon said plates or bars, perfectly parallel,
and square with the rolled surface. By means of the small regulating screw G, the
vertical adjustment of the top rider K, may be accurately defined, and carried
out with celerity, and the horizontal adjustment of the upper roll L, may also be
effected to great nicety, by means of the screwed wedges E E, and also the
wear of the bearings compensated for, without destroying the equilinear "set" of
the rolls.
•
In the case of heavy rolls I may dispense with the breaker or projection U, carrying
the regulating screw G, and place the latter in a corresponding screwed recess, within
the top carriage or top rider K.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :
1st. The method of and means employed for effecting the parallel and simultaneous
adjustment of the side guards, or guide cheeks of a rolling mill, and the similar
adjustment of vertical edge rolls and horizontal and vertical adjustment of "top roll"
substantially as set forth.
2nd. In a rolling mill the combination of vertical edge rolls with screwed
adjusting shafts and gearing, adjustable side guards or guide cheeks, screwed adjusting
shafts and gearing, with screwed wedges and regulating screws interposed between the
supports or main screws of the fixed portion of said rolling mill and the suspended
carriages, intermediate or lower suspended carriage bearings for purposes of adjust-
ment substantially as herein described and set forth.
3rd. In a rolling mill the use of a short regulating screw G. Fig. 3. either sunk
into a recess within the top carriage or top rider K. or enclosed within the breaker
for the purpose of effecting the very fine vertical adjustment of the "
top roll"
substantially as herein described & set forth.

page_text: 4th. In a rolling mill the method which I adopt for effecting the horizontal
adjustment of the top roll by means of the screwed wedges EE and the similar
adjustment of the lower roll or intermediate rolls by means of the screwed
wedges H H Fig. 5 and tapered liner J substantially as herein set forth & shewn in
the accompanying drawings.
