COMPLETE SPECIFICATION.
Improvements in and relating to the Bearings of Rolling Mills.
We, FRANCIS FREDERICK SIMPSON, of Park Lane, Oldbury, in the County
of Stafford, Ironmaster and JOHN THOMAS SKIDMORE, of Tetford Road,
Oldbury, aforesaid, Roller, do hereby declare the nature of our said invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
Our invention has for its object improvements in the chucks for housings or
bolsters and in the mode of applying the same to the journals of the rolls which is
specially applicable to mill and forge work where the rolls sustained is of a very
heavy nature, by which we relieve the bearing of the middle roll of the weight of
the chucks and top roll while the top roll is relieved of the weight of the top chuck
and all pressure is relieved from the whole during such time as the rolls are not
doing their work, while particular facilities are rendered by our improvements for
easily retaining the suet in the required position.
In order that our invention may be clearly understood and more easily carried
into practice we have appended hereunto a double sized sheet of drawings upon which
we have fully illustrated the nature of our said improvements and the manner of
carrying the same into effect.
Figure 1, is a section through the journals of a set of rolls used in ordinary mill
and forge work showing an elevation of the housing and chucks.
In carrying our invention into effect we support the lower chuck of the central
roll H upon the brackets or projections a¹ which are formed at each side of the
housing A of the rolls. The lower chucks B which are supported by the pro-
jections a¹ are provided with side lumps B¹ which are just short of the required
height to support the chuck B or C as the case may be which is above it so that
by the application of the liners M the whole force of the pressure of the handle E
through the screw D and the whole weight of the rolls H and H' and holsters B
and Care carried by the said projections a¹. The liners are so arranged that the
top bearing blocks K only come into full friction when the rolls are doing their
work while the lower bearing blocks when the rolls are normally at work only
have the friction consequent upon the weight of that particular roll by which
means the life of the bearing blocks or pieces K are very much longer than
hithertofore while the work of adjustment is very small. For the purpose of
preventing the liners M from being worked or shaken out of position the lumps B¹
are provided with recesses 63 into which the tits 62 enter so that the sides of
the said recesses tend to steady the liners and retain them in position. We may
however accomplish the desired ends as at first described without the aid of the
tits and recesses. The bottom rolls are not affected by this invention, the chucks
for which are not shown. The space F formed by the side lumps B₁ formed on
the chucks, form a receptacle of convenient size and shape for holding the suet
for lubricating the bearings and for the purpose of assisting to retain the chucks
in a cool condition, the perforations are provided.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what
we claim 18:—
Improvements in the chucks for housings or holsters and in the mode of

page_text: applying the same to the journals of the rolls, substantially as and for the purpose
herein set forth and shown upon the accompanying drawing.
Dated this 1st day of September 1894.
