I, RICHARD RUSSELL GUBBINS of 17 Park Road New Cross in the County of Kent
Engineer do hereby declare the nature of this invention to be as follows:-
This invention has for its object means for readily changing the Rolls used in the
manufacture of iron, so that the time now occupied in altering the "Mill" from one sort
of work to another may be saved. I accomplish this by having a number of pairs or sets
of Rolls of various kinds suitable for the various kinds of iron to be manufactured,
arranged in Housings, each pair of which forms one arm of a double Cross, and this is
mounted in such a manner that it can be revolved on a stout shaft in bearings which are
firmly secured on opposite sides of a pit in the floor of the building. By this means I
provide a number of Rolling Mills each of which is complete in itself and any one
of which, may by rotating the shaft be brought uppermost ready for use at a moment's
notice. In carrying out my invention I provide a pair of cruciform castings, each
arm of which forms one of a pair of Housings similar in all respects to the ordinary
Housings now in use and furnished with Rolls either two or three high, or as may be
required. In the case which I am now describing where a revolving Housing with
four arms is used, one pair may be furnished with Rolls for rolling flats" another
pair for "squares another for "rounds" and the fourth pair for "ovals," but it is
plain that the arrangement may be altered at pleasure to other varieties of iron as for
example, sheets, angles, &c. &c.
Upon each cruciform casting above described & in the centre thereof, a large boss
is cast and these being bored out truly they are both so mounted upon a shaft that
the different pairs of Housings coincide with one another and the whole is then
placed in suitable bearings across a pit, dug in the floor, at such a level that the pair
of Housings which are for the time being vertical, come in line with those of the
driving pinions, and consequently in a suitable position for working. The other three
pairs of Housings and their Rolls &c.' are meantime below the level of the floor and are
completely out of the way, but when any one of them is wanted then by uncoupling
the pinions and removing portions of the floor, which are made moveable for this
purpose, the shaft, Housings & Rolls may all be revolved together until the set wanted
is on top; the floor is then relaid the pinions coupled on, and operations are

page_text: immediately resumed. Although, I have here described a four armed revolving
arrangement of Roller Housings, I do not confine myself to this number, two or
three pairs may be readily used and five or six or more may be found desirable in
some cases where a very large variety of Rolls is required.
Datad this 27th day of December 1887.
"
I, RICHARD RUSSELL GUBBINS, of 17 Park Road, New Cross, in the County of
Kent, Engineer" 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:-
My invention has for its object means for readily changing the rolls used in the
manufacture of iron so that the time now occupied in altering the mill from one sort
of work to another may be saved.
I accomplish this by having a number of pairs or sets of rolls of various kinds
suitable for the various kinds of iron to be manufactured, arranged in housings, each
pair of which forms one arm of a double cross, and this is mounted in such a manner
that it can be revolved on a stout shaft in bearings which are firmly secured on
opposite sides of a pit in the floor of the building. By this means I provide a
number of rolling mills each of which is complete in itself, and any one of which,
may by rotating the shaft be brought uppermost ready for use at a moment's
notice.
In carrying out my invention I provide a pair of cruciform castings, each arm of
which forms one of a pair of housings similar in all respects to the ordinary housings
now in use; and furnished with rolls either two or three high, or as many as may
be required.
In the case which I am now describing, where a revolving housing with four arms
is used, one pair may be furnished with rolls for rolling flats," another pair for
squares," another for "rounds," and the fourth pair for ovals"; but it is plain that
these arrangements may be altered at pleasure to other varieties of iron as for example,
sheets, angles, channels, halfrounds, etc.
Upon each cruciform casting before described and in the centre a large boss is cast
and so being bored out truly they are both so keyed upon a shaft that the different
pairs of housings coincide with one another, and the whole is then placed in suitable

page_text: bearings across a pit, dug in the floor, at such a level that the pair of housings which
are for the time being vertical, come in line with those of the driving pinions, and
consequently in a suitable position for working.
The shaft where it enters the bearings has two holes drilled through at right angles
to each other, a hole is also drilled through the cap of the boaring, and through these
a pin is inserted, to prevent the shaft from turning round, and fixes the shaft in the
required position. The other three pairs of housings and their rolls etc. are meantime
below the level of the floor and are completely out of the way; but when anyone
of them is wanted then by uncoupling the pinions, and removing portions of the floor,
which are made moveable for this purpose and pulling out the pin the shaft, housings
and rolls may all be revolved together, until the set wanted is on top; the floor is
then relaid, the pinions coupled on the pin replaced and operations are immediately
resumed.
Although I have described a four armed revolving arrangement of roller housings,
I do not confine myself to this number, two or three pairs may be readily used, and
five or six or more may be found desirable in some cases where a very large variety
of rolls is required.
And in order that my invention may be thoroughly understood, I now proceed to
describe the accompanying drawings thereof, reference being had to letters and figures
marked thereon.
Figure 1. represents the front elevation of the apparatus erected in a pit, formed in the
floor, with the cruciform frames fixed on a shaft, which shaft works on bearings, these
bearings being built in the brick work of the pit. This figure represents the rolls
for the "rounds" at the top, and the rolls for the "squares" at the bottom. The side
rolls are omitted on purpose to show the shaft.
Figure 2, denotes the sectional view of the apparatus on line a, b, of figure 1.
Like letters refer to like parts in each of the figures.
A. The cruciform housings. B. The rolls. C. The floor plates. D. The shaft.
E. The pit. F. The bearers. G. The housing screws. H. The bearings. I. The
brickwork. J. The boss. K. The pins. L. The pinions. N. The Couplings.
Having now fully described the nature and object of my invention, and the
manner in which the same is to be performed, I claim as new the following
:
--
First The combination of the apparatus for readily changing the rolls used in
the manufacture of bar iron, so that the time now occupied in altering the mill from
one sort of work to another is saved, substantially herein described and according to
the accompanying drawings.

Secondly: The combination of the machine, either cruciform or any number of
arms, fixed on a shaft to revolve on bearings, each arm having the rolls set either for
squares, rounds," ovals,"
""angles,"
"channels" etc. complete in themselves on
either arm, which by rotating the shaft may be brought uppermost ready for use at a
moments notice, substantially herein described and according to the accompanying
drawings.
