Improvements in and relating to the Method of Working Live
Rollers and Transferring Tables in Plate Rolling and other Iron
and Steel Rolling Mills.
We, A. AND J. STEWART AND CLYDESDALE, LIMITED, Iron and Steel
Manufacturers, of 41 Oswald Street, Glasgow, Lanarkshire, and FINLAY
FINLAYSON, Consulting Engineer, to said Company, do hereby declare the nature
of our invention to be as follows:-
This invention has reference to and comprises a new or improved method and
arrangement and combination of mechanism or appliances for working live rollers
and transferring tables in plate rolling and other iron and steel rolling mills.
The practice followed hitherto has been to operate these transferring carriage
tables with their live rollers by stationary power it being communicated to the
tables by means of shafting, and also by wire ropes.
Our improvements essentially consist in making the tables carrying the live
rollers self contained, that is to say, we so arrange the table that the engine and
the boiler for supplying steam to it, are carried on a platform which is attached to
the tables. By this improvement we get a range for the distribution of the finished
plates which is limited only by the extent of the mill floor for laying the rails of
the traversing carriage, and thus the rolling operations are not hampered by the
accumulation of finished and hot plates in close proximity to the rolling mill.
In carrying these improvements into practice under one arrangement, the
carriage frame, carrying the transferring table and its live rollers, is made
sufficiently long at one side over the rails to mount on it the steam boiler and
engine, both preferably of the vertical type to save room, and also the first motion
driving gearing. The driving gearing would preferably consist of a pinion on the
crank shaft of the engine gearing into a large speed reducing spur wheel on a clutch
shaft mounted over the traversing carriage frame, the clutch lever mechanism being
placed convenient to the engineman, for either putting the live roller gearing or
the traversing carriage platform gearing into action as required. The clutch
shaft is preferably placed at right angles to the live roller shafts, but on a level
with the intermediate cross shafts between them which drive them by the usual
spur gearing on these shafts. One of these intermediate shafts near the centre is
continued forward so as to be driven by a pair of bevel or mitre wheels direct from
the clutch when put in gear with these so as to drive the live rollers above the
traversing carriage frame. This first clutch gear shaft by a spur wheel with the
clutch on it actuates a shaft carried on bearing blocks below the traversing frame
which by bevel or mitre wheels on it drives two or more longitudinal shafts, and
these by bevel gear at their other end drive one or it might be both of the long
carriage wheel shafts running on the rails below the traversing live roller frame,
when the clutch is put in gear with the said spur wheel on the clutch shaft. Other
modifications of the intermediate driving gear might be employed, such as bevel
wheels or sprocket wheels and pitch chains, to drive the second or third carriage
wheel shafts under the engine carriage frame, from the first carriage shaft; and
other modifications of the motive engine and driving gear might be used.

Improvements in and relating to the Method of Working Live
Rollers and Transferring Tables in Plate Rolling and other Iron
and Steel Rolling Mills.
We, A. AND J. STEWART AND CLYDESDALE, LIMITED, Iron and Steel
Manufacturers, of 41 Oswald Street, Glasgow, Lanarkshire, and FINLAY
FINLAYSON, Consulting Engineer to the said Company do hereby declare the
nature of our invention and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement
in writing that is to say :-
This invention has reference to and comprises a new or improved method and
arrangement and combination of mechanism or appliances for working live rollers
and transferring or traversing tables in plate rolling and other iron and steel
rolling mills.
:
The practice followed hitherto has been to operate these transferring carriage
tables with their live rollers by stationary power it being communicated to the
tables by means of shafting and also by wire ropes.
Our improvements essentially consist in making the tables carrying the live
rollers selfcontained, that is to say we so arrange the table that the engine and the
boiler for supplying steam to it, are carried on a platform which is attached to the
tables. By this improvement we get a range for distribution of the finished plates
which is limited only by the extent of the mill floor for laying the rails of the
traversing carriage, and thus the rolling operations are not hampered by the
accumulation of finished and hot plates in close proximity to the rolling mill.
And in order that our said invention and the manner of performing or carrying
the same into effect or practice may be properly understood we have hereunto
appended an explanatory sheet of drawings in which the same reference letters are
used to indicate corresponding parts in all the figures where shown.
Figure 1 is an end elevation Figure 2 a horizontal section broken away, and
Figure 3 a corresponding side elevation broken away, illustrating our improvements
as applied to a plate or iron and steel rolling mill.
Referring to these drawings:-In carrying these improvements into practice
under this arrangement, the carriage frame A carrying the transferring table A'
and its live rollers a is made sufficiently long at one side over the rails to mount on
it the steam boiler B and engine B' both preferably of the vertical type to save
room, and also the first motion driving gearing. The driving gearing would
preferably consist of a pinion b on the crank shaft 6' of the engine B' gearing into
a large speed reducing spur wheel 6 on a clutch shaft c mounted over the traversing
carriage frame, the clutch lever mechanism being placed convenient to the engine-
man for either putting the live roller gearing or the traversing carriage platform
gearing into action as required.
The clutch shaft c is preferably placed at right angles to the live roller shafts a¹
but on a level with the intermediate cross shafts between them which drive them by
the usual spur gearing all on these shafts a².
One of these intermediate shafts a² near the centre is continued forward so as to be
driven by a pair of bevel or mitre wheels as a direct from the clutch when put in
gear with these so as to drive the live rollers a above the traversing carriage
frame.
This first clutch gear shaft c by a spur wheel,c' with the socket part d' of the
clutch on it actuates through a spur wheel a shaft e carried on bearing blocks
below the traversing frame A and which through bevel or mitre wheels ee², el e³,
on it drives two or more shafts es, e, and these by level gear ff' at their other end
drive one or it might be both of the long carriage wheel shafts f* running by their
wheels on the rails f¹¹ below the traversing live roller frame when the part d
...

page_text: of the clutch is put in gear with the part d' on the said spur wheel c' on the clutch
shaft c.
Other modifications of the intermediate driving gear might be employed, such as
bevel wheels or sprocket wheels and pitch chains to drive the second or third
carriage wheel shafts under the engine carriage frame from the first carriage shaft;
and other modifications of the motive engine and driving gear might be used, such
as having an electro or other operating motor instead of a steam engine.
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 is:—
First. In rolling mills, the method of actuating the traversing carriage tables
and their live rollers by direct power, consisting in mounting the engine and steam
boiler or operating motor on a platform attached to the traversing table, substan-
tially as herein described in reference to and by way of application shown in the
accompanying drawings.
Second. In rolling mills, the mounting of the primary motor on the traversing
table platform, in combination with wheel and clutch gearing for operating the live
rollers, and travelling carriage respectively, substantially as herein described in
reference to and shown in the accompanying drawings.
