Complete Specification Accepted, 7th Dec., 1888
1, CHARLES DAVY, of 30 Whitworth Road Ranmoor Sheffield in the County of
York, Engineer, do hereby declare the nature of this invention to be as follows:
My Invention relates to the feed or conveying rollers of a Rolling Mill; and it has
for its object to enable the slab or plate to be rolled, to be readily turned in its own
plane and presented in any required direction to the rolling mill rolls for the purpose
of being thereby rolled out lengthwise or cross-wise to the desired length and width.
The Invention consists of a double set of feed or conveying rollers at one or both
sides of the rolling mill, the two sets, which are placed side by side and together
correspond in width to an ordinary single set, being capable of being driven conjointly
or independently in the same or in opposite directions, as may be required, that is to
say, for conveying the slab or plate to and from the rolls, the two sets would revolve
together in the same direction, the two sets then acting together as an ordinary single
set, or the rollers of one set may be caused to revolve in one direction, whilst those
of the other revolve in the opposite direction or remain stationary, according as it is.
desired to turn the plate horizontally, or to turn it and also move it. sideways on the
feed rolls.
The two sets of rollers may be driven by separate engines, but it is preferred to
employ one pair of reversing engines to drive the two sets of rollers through the
medium of change gear and a reversing clutch, whereby the change in the relative
motion of the two sets may be effected.

page_text: CHARLES DAVY O 50, Witworth xoad, hanmoor, Suemeid, m the County or
York, 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 relates to the feed or conveying rollers of a plate Rolling Mill; and
it has for its object to enable the slab or plate to be readily turned in its own plane
and presented in any required direction to the rolling mill rolls for the purpose of
being thereby rolled out lengthwise or crosswise until it has attained the desired
length and width.
The Invention consists of a divided or double set of feed or conveying rollers, the
two sets, which are placed side by side and together correspond in width to an
ordinary single set, being driven conjointly or independently in the same or in
opposite directions, as may be required.
Thus, the two sets would be revolved together in the same direction for the purpose
of conveying the slab or plate to and from the rolls, and they would then act together
as an ordinary single set. Or, the rollers of one set may be caused to revolve in one
direction whilst those of the other revolve in the opposite direction or remain
stationary, according as it is desired to turn the plate horizontally or to turn it and
also move it sideways on the feed rolls.
The two sets of rollers may be driven by separate engines; but it is preferred to
employ one pair of reversing engines to drive the two sets of rollers through the
medium of change gear and a reversing clutch whereby the change in the relative
motion of the two sets may be effected.
Reference is to be had to the accompanying drawings forming part of this speci-
fication in which figure 1 is a plan of a rolling mill provided with the duplex feed
rollers of my invention, at each side of the rolling mill. Figure 2 is a section on
line 1-1, figure 1, drawn on a larger scale. The same letters of reference serve for
like parts in both figures.
A A and B-B are the duplex feed rollers mounted. in bearings in side and centre
frames C. The rollers of the one set A receive motion through bevel gear from a
shaft a and those of the other set B from a shaft b, both these shafts being by
preference driven from a cross-shaft d the one directly and the other through a
clutch D for changing the relative direction of rotation of the shafts a and b, or for
enabling the shaft a to be driven whilst the shaft b remains stationary. This shaft d
is driven by a pair of engines, not shewn, fitted with link motion reversing gear.

page_text: Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed, I declare that what I claim is :-
The combination for feeding or conveying slabs or plates to a plate-rolling mill, of
two juxtaposed sets of feed or conveying rollers and of gear whereby the two sets may
be driven conjointly or independently in the same or opposite directions, as and for
the purpose specified.
