PROVISIONAL SPECIFICATION.
Improvements in the Housings of Rolling Mills.
I, WILLIAM BEARDMORE, of Parkhead Forge, Parkhead, in the County of
Glasgow, North Britain, Steel Manufacturer, do hereby declare the nature of this
invention to be as follows, that is to say:-
In rolling mills as hitherto constructed the housings consist of massive metal
castings and when such mills are used for rolling heavy metal plates, such, as
armour plates for example, or other massive pieces of metal, considerable strain
is put on the housings and these housings often break under such strain. By my
invention the possibility of the housings breaking is prevented or greatly
diminished my improved housings being not only stronger and more durable in
use than housings as at present constructed but at the same time they are also
lighter.
In carrying out my invention instead of forming the housings of rolling mills
of massive castings I form each housing of two or more steel plates of an desired
thickness and bolted together at intervals, distance pieces of metal being inter-
posed, if desired, between the plates. The plates are each formed, by hydraulic
pressure or otherwise, of the necessary shape and with the necessary openings
to suit the "
screw box," and gearing of the mills; and they may, if desired, have
additional suitably shaped blocks of metal bolted on externally at the bottom of
the plates to serve as a base or sole plate for the housing.
Dated this Eighteenth day of May 1898.

Improvements in the Housings of Rolling Mills.
I, WILLIAM BEARDMORE, of Parkhead Forge, Parkhead, in the County of
Glasgow, North Britain, Steel Manufacturer, 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, that is to say: -
In rolling mills as hitherto constructed the housings consist of massive metal
castings, and when such mills are used for rolling heavy metal plates such as
armour plates, or other massive pieces of metal, considerable strain is put on the
housings and often causes their breakage. By my invention the possibility of
the housings failing is prevented or greatly diminished, my improved housings
being not only stronger and more durable than housings as hitherto constructed

page_text: but at the same time they are also lighter relatively to the strain they can
withstand.
In carrying out my invention I make each housing of a rolling mill of rolled
steel plates of suitable dimensions and thickness, there being in each housing a
pair of such plates bolted together with distance pieces between them.
And in order that my said invention and the manner of performing the same
may be properly understood I hereunto append a sheet of explanatory drawings
to be hereinafter referred to and representing a rolling-mill housing as made
with my improvements.
Figure, 1, of the drawings is a plan, Figure, 2, an elevation, Figure, 3, a
horizontal section, and Figure, 4, a vertical section. In these drawings the same
reference letters are used to mark the same or like parts wherever they are
repeated.
The housing is built up of two main plates, A, of steel shaped like a frame,
and fixed together by bolts, B, with distance pieces, C, between them, these
distance pieces being at the sides. The upper parts of the main plates, A, are by
hydraulic pressure made to take the shape best seen in Figure, 1, that is to say
with nearly-half-round parts, D, for holding the screw box, E, this box being
made with lateral projections to enter a short distance between the plates, A, and
to receive through them some of the bolts, B. At the bottom of the housing,
massive blocks or plates, G, are secured at both outer and inner sides of the
main plates, A, by bolts, H, passing quite through, and serve to strengthen and
broaden the base of the housing.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
The constructing of rolling-mill housings each with two or more steel plates
bolted together and formed substantially as hereinbefore described.
