Improvements in Feeding "Slabs" or "Blooms" to Rolling Mills.
I, FRANK WESLEY DICK, Steel and Iron Works Department, Messrs. Palmer's
Shipbuilding and Iron Company Limited Jarrow on Tyne in the County of
Durham, Engineer and Manager of Steel and Iron Works 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 :-
The object of this invention is to allow a "driven" feed roller to be placed
sufficiently near to the main rolls of a mill to enable it to feed in short "slabs" or
blooms
without the intervention of manual labour.
"
"
In rolling plates or bars it is well known that "guards" are necessary, to prevent
the "piece" being carried round the rolls on the leaving side. The ordinary mode.
of supporting these "guards" is by a cramp bar between the main rolls and
the first feed roller and this, of necessity causes the feed roller to be at a con-
siderable distance from the mill rolls. To obviate this objection feed rollers with
collars have been adopted with the object of getting nearer to the mill the guard
consisting of a slotted plate into the slots of which the collars of the feed roller fit
projecting above the "guard," but such "guards" have always been more or less
unsatisfactory and difficult to maintain in position.
According to my invention the "guards" are formed of girder section of great
strength and firmly secured and maintained in position and the driven feed roller
is brought as close as necessary to the mill rolls as shewn on the drawings.
On the accompanying sheet of drawings
Figure is a front elevation of a mill fitted with my invention, Figure 2 is an
end elevation in section through the driven feed roller and the guard and Figure 3.
is a plan on top.
"
The "housings " and rolls are shewn by dotted lines and the driven rollers and
the " guard-plate with its framing by full lines. The "guard plate" is formed
of a series of trough shaped horns A with spaces between, strongly bracketted and
forming one continuous base A' below, resting like a saddle upon a "cramp-bar" B
in the usual manner; or the bottom of the trough girder may be formed so as to
rest upon and be fixed to the mill bedplates and adjusted in height by wedges or
similar means.
The driven feed roller C is formed with collars C which fit into
the spaces between the horns of the "guard plate" A and project above the top
level. The horns of the " guard plate" extend on one side close up to the mill
roll D and on the other side close up to the second feed roller E (see Figures 2
and 3).
The "guard plate" is capable of adjustment both in height and in relation to
the mill roller D upon the "cramp-bar "B and the driven feed roller C can be
taken out at any time, through the open trough, from its bearings F and upward
through guide slots G in the mill framing H without disturbing the "guard plate."
The driven feed roller C and the second feed roller E are revolved in the same
direction (indicated by the arrows) by a driven shaft J from the prime mover
carrying a spur wheel K gearing into the spur wheels L and M on the axles of the
driven feed rollers C and E respectively.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
First
consisting of a

guard-plate" permanently fixed so as to be adjustable close up to

page_text: the mill roll and to the ordinary driven feed roller, and of such shape as to admit
between its sides a driven feed roller formed with collars which project into spaces
between the "guards and above the top of the "guard-plate" said driven feed
roller being capable of being placed in its bearings or removed therefrom without
disturbing the guard-plate" substantially as described and with the objects
hereinbefore stated.

Second-The combination of a trough shaped "guard-plate" permanently fixed
to a "cramp bar" or to the mill bedplate or foundation, so as to be adjustable as
to height, with a driven feed roller, formed with collars, the main diameter fitting
between the sides of the "guard-plate," and being supported in suitable bearings,
the collars, projecting into spaces between the "guards," and above them to propel
the "slab or "bloom; constructed and operating substantially as described and
shewn by the drawings with the objects hereinbefore stated.
