Improvements in or relating to the Treatment of Split Bars, Plates,
or the like. .
I, MONTAGUE HERBERT CHURCHILL SHANN, of Shoreham, in the County of
Sussex, Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to the treatment of split bars, plates or the like with
the object of dealing independently with the separated portions. The invention
is applicable to various forms of bars, plates and the like for various purposes,
but I will describe it as applied to bending or bevelling ships frames made of
Z section, one end of which is split so that the divided portions may be separated
to form the double bottom of a ship.
In carrying out the invention I prefer to treat the bar generally and particu-
larly the undivided portion by apparatus such as is described in my previous
Patents Nos. 12256 and 19623 of 1896, the present invention although applic-
able to other kinds of machines being particularly suitable for use in conjunction
with the machines described in those specifications. It will be therefore under-
stood that the new mechanism may be used in conjunction with or as forming
part of the machines described in the earlier specifications.
The bar to be treated comes through the set of rolls described in my Specifi-
cation No. 19623/96 but some of those rolls or some additional ones are made
double instead of single, their supporting shafts being carried in bearings upon
different portions of the ring or supporting frame which is divided and carried
in slides or otherwise suitably arranged so that the divided rolls may be separ-
ated either for the purpose of drawing apart or separating the divided portions
of the bar at the split, or so as to be able to follow the divided portions should
they have been already separated.
The operation can be continued to the extreme end of the bar or may be
discontinued earlier if preferred, the mechanism being suitable for either pur-
pose. For this purpose I may if desired lock or otherwise secure one or more
of the adjustable rolls or sets of rolls in any desired position perhaps beyond
the normal. Provision is made in the framing or positions of the rolls to allow
free passage to the bar both in its whole or divided portion or condition.
I do not bind myself as to any particular shape, size or position of the
rolls and other parts, but I find it convenient to make those rolls which are
intended to separate so as to lie to a considerable extent one within the other,
each roll being preferably hollow and of conical form.

or the like.
I, MONTAGUE HERBERT CHURCHILL SHANN, of Shoreham, in the County of
Sussex, Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to the treatment of split bars, plates or the like with
the object of dealing with one portion independently of the separated portion.
The invention is applicable to various forms of bars, plates and the like for
various purposes, but I will describe it as applied to bending or bevelling ships
frames made of Z-section, one end of which is split so that the divided portions
may be separated to form the double bottom of a ship.
In carrying out the invention I prefer to treat the bar generally and particu-
larly the undivided portion by apparatus such as is described in my previous
Patents Nos. 12256 and 19623 of 1896, the present invention although applic-
able to other kinds of machines being particularly suitable for use in conjunction
with the machines described in those specifications. It will be therefore under-
stood that the new mechanism may be used in conjunction with or as forming
part of the machines described in the earlier specifications.
The bar to be treated comes through the set of rolls described in my Specifi-
cation No. 19623/96 but some of those rolls or some additional ones are made
double instead of single, their supporting shafts being carried in bearings upon
different portions of the ring or supporting frame which is divided and carried
in slides or otherwise suitably arranged so that the divided rolls may be separ-
ated either for the purpose of drawing apart or separating the divided portions
of the bar at the split, or so as to be able to follow the divided portions should
they have been already separated.
The operation can be continued to the extreme end of the bar or may be
discontinued earlier if preferred, the mechanism being suitable for either pur-
pose. For this purpose I may if desired lock or otherwise secure one or more
of the adjustable rolls or sets of rolls in any desired position perhaps beyond
the normal. Provision is made in the framing or positions of the rolls to allow
free passage to the bar both in its whole or divided portion or condition.
In the accompanying drawings
Figure 1 shows diagrammatically a set of rolls arranged according to this
invention.
A, A¹ are double rolls, the supporting shafts of which are carried in bearings
upon different portions of the supporting frame, B and C being rolls operating
on the opposite surfaces of the bar or plate to those operated on by A A' respec-
tively. The roll A is mounted on the supporting frame in such a manner as
to be capable of regulated automatic or other movement along the dotted line <,
one such position of the roll A being indicated in dotted lines in the drawing.
Preferably the roll B is a conical one as shown, its shaft being parallel to
the shaft of the roll A.
It is evident that this arrangement permits of a
to the bar.

Figure 2 is a longitudinal vertical section, partly in elevation, of the body of
a rolling machine showing a convenient method of carrying out the invention
as applied to a bending and rolling machine such as is described in Patent
No. 19623/96 before referred to.

page_text: The bracket D is preferably formed of two symmetrical parts, each com-
prising a body or web D', lugs D2, D3, and an extension D, the two portions
being rigidly secured together, say by bolts in holes D³ in the lugs, extension
and upper part of the body.
The free ends of the extension I form a bearing to receive one end. E¹ of a
sleeve E, side motion of the sleeve within the bearing being prevented by
collars E E³; the other end of the sleeve is provided with a gear wheel E.
The sleeve E is capable of reciprocation on the squared portion F₁ of a shaft F,
carried in bearings G1 G2 of the main frame G of the machine and capable of
rotation through the gear wheel F³.
The lugs D2 D3 form bearings to receive a shaft A2, which carries the roll A
at one end, and a gear wheel A³, engaging the gear wheel E, at the other. The
pressure on the roll A is upwards, and the lower part of the bearing formed by
the lugs D³ may be safely cut away, as shown in the figure, to allow of the
treatment of Z-bars.
The bracket D is connected to one end of the piston rod H, on which is secured
a piston H', capable of reciprocating in a cylinder H2, secured on a cross plate G³
of the main frame. Valves and connections (not shown in the figure) are pro-
vided for admitting steam or other fluid the cylinder H2 to operate the
piston H³ to reciprocate longitudinally the roll A. and its operating gear A³ E¹
through the bracket D, its extension D4 and the sleeve E.
The rolls A, B and C are mounted independently of the bracket D, on frame-
work similar in character to that described in the Patent No. 19623/96 before
referred to. The roll B is operated through gears B1 B2 B3 by gear wheels F
on the shaft F, which also rotates the roll A.
Having now particularly described and ascertained the nature of the said in-
vention and in what manner the same is to be performed, I declare that what
I claim is:-
1. In a metal rolling machine the employment of a roll adapted to be moved
apart from the other rolls of the same series to remove it out of the way of the
bar while the latter is being operated upon by the other rolls.
2. In a metal rolling machine the combination of two rolls such as A and B,
one roll being capable of movement. nearer to or farther from the other whilst
maintaining the parallelism of their axes of rotation substantially as described
or as illustrated in in Fig. 1 or in Fig. 2 of the accompanying drawings.
3. In a metal rolling machine the combination and arrangement of rolls sub-
stantially as described or illustrated in Fig. 1 or in Fig. 2 of the accompanying
drawings.
