PROVISIONAL SPECIFICATION.
A New or Improved Bearing for the Necks of Rolls.
I, ARTHUR WESTLEY, trading as Arthur Westley and Co. of Kate's Hill
Brassfoundry, Dudley, in the County of Worcester Brassfounder do hereby declare
the nature of this invention to be as follows:-
My invention consists of a new or improved bearing for the necks of rolls
constructed as hereinafter described.
Bearings of the kind to which my invention refers are commonly called hot neck
bearings and are principally used for supporting the necks of tin plate mill rolls:
iron and steel sheet and plate mill rolls and other like rolls.
The object of my invention is so to construct the bearings of the necks of the said
rolls as to reduce to a minimum the tendency of the said necks to break at the
"fillet "
or the curved shoulder of the neck where the neck joins the body of the
roll
By the use of bearings of the ordinary kind, fine surface cracks are formed at the
"fillet" or curved shoulder of the neck of the roll in consequence of the excessive
friction at and overheating of that part of the roll, and at the said cracks the necks
frequently break or split.
prevent the production of the said fine surface cracks and thereby reduce to a
minimum the breaking of the necks at the "fillet" or curved shoulder by the use of
bearings constructed according to my invention.
In a bearing of the ordinary kind the inner end of the bearing situated under the
"fillet" or curved shoulder of the neck of the roll is curved or made convex for the
" fillet" or curved shoulder of the neck of the roll to seat itself closely upon,
the whole of the neck of the roll resting on the bearing, that is, the cylindrical part
of the neck rests on the horizontal part of the bearing and the "fillet" or curved
shoulder on the convex inner end of the bearing.
"
or curved
In making a bearing according to my invention I form a recess at the inner end
of the bearing and at that face when the bearing is in use which is presented to the
"fillet
or curved shoulder of the neck of the roll so that the said "fillet
shoulder of the neck does not come in contact with the bearing, the whole bearing
surface of the neck of the roll being supported on the horizontal part of the bearing
so that overheating at the "fillet" part of the neck of the roll is wholly prevented.
The rolls are kept in position by the snugs and collars bearing against the body of
the rolls sideways as usual.
I prefer to make my improved bearing of bronze the recess situated under the
"fillet " or curved shoulder of the neck extending nearly across the bearing and the
bottom of the recess may either be curved or angular.
In addition to preserving the necks of the rolls, bearings made according to my
invention possess the minor advantages that less friction being produced at the neck
a reduced quantity of lubricant is necessary and less power is required for driving
the rolling mill.

A New or Improved Bearing for the Necks of Rolls.
I, ARTHUR WESTLEY, trading as Arthur Westley and Co., of Kate's Hill
Brassfoundry, Dudley, in the County of Worcester, Brassfounder do hereby
declare the nature of my 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 consists of a new or improved bearing for the necks of rolls
constructed as hereinafter described.
Bearings of the kind to which my invention refers are commonly called hot neck
bearings and are principally used for supporting the necks of tin plate mill rolls:
iron and steel sheet and plate mill rolls and other like rolls.
The object of my invention is so to construct the bearings of the necks of the said
rolls as to reduce to a minimum the tendency of the said necks to break at the
"
fillet or the curved shoulder of the neck where the neck joins the body of the
roll.

By the use of bearings of the ordinary kind fine surface cracks are formed at the.
"fillet" or curved shoulder of the neck of the roll in consequence of the excessive
friction at and overheating of that part of the roll, and at the said cracks the
necks frequently break or split.
I prevent the production of the said fine surface cracks and thereby reduce to a
minimum the breaking of the necks at the "fillet or curved shoulder by the use of
bearings constructed according to my invention.
In a bearing of the ordinary kind the inner end of the bearing situated under the
"fillet" or curved shoulder of the neck of the roll is curved or made convex for
the "fillet" or curved shoulder of the neck of the roll to seat itself closely upon, the
whole of the neck of the roll resting on the bearing, that is, the cylindrical part of
the neck rests on the horizontal part of the bearing and the " fillet" or curved
shoulder on the convex inner end of the bearing.
In making a bearing according to my invention I form a recess at the inner end
of the bearing and at that face when the bearing is in use which is presented to the
"fillet
or curved shoulder of the neck of the roll so that the said "fillet" or
curved shoulder of the neck does not come in contact with the bearing, the whole
bearing surface of the neck of the roll being supported on the horizontal part of the
bearing so that overheating at the "fillet" part of the neck of the roll is wholly
prevented. The rolls are kept in position by the snugs and collars bearing against
the body of the rolls sideways as usual.
I prefer to make my improved bearing of bronze the recess situated under the
-"fillet "
or curved shoulder of the neck extending nearly across the bearing and the
bottom of the recess may either be curved or angular.
In addition to preserving the necks of the rolls, bearings made according to my
invention possess the minor advantages that less friction being produced at the
neck a reduced quantity of lubricant is necessary and less power is required for
driving the rolling mill.
Figure 1 of the accompanying drawing represents in side elevation, partly in
longitudinal section, a portion of a cylindrical roll to which a bottom hot. neck
bearing constructed according to my invention is applied and
Figure 2 represents an end elevation of the same;
Figure 3 represents in plan, longitudinal section and elevation, taken at the
recessed inner end, my improved bearing detached from the roll.
The same letters of reference indicate the same parts in the several figures of the
drawing.
a is the cylindrical body of the roll: 6 is the neck of the roll and c the fillet or
curved shoulder where the neck joins the body of the roll; d is the wabbler of the

page_text: roll. The bottom bearing of the neck constructed according to my invention is
marked e, f. The bearing is of the ordinary kind excepting at the inner end or
that end which when the bearing is in use is presented to the fillet or curved
shoulder c of the roll. At the said inner or fillet end of the bearing I make the
recess which extends nearly from side to side of the said bearing. The shape and
position of the said recess will be understood by an examination of Figure 1 and
the separate bearing Figure 3. The said recess fis curved at bottom, but the said
recess may be square or of other angular figure instead of curved as represented in
the drawing.
It will be seen by an examination of Figure that when the bearing is in use, the
recess fat its inner end, is situated under the fillet or curved shoulder c of the neck
of the roll and that the said fillet or shoulder does not come in contact with the
bearing, the whole bearing surface of the neck of the roll being supported on the
horizontal seat part e of the bearing, instead of the whole of the neck resting on
the bearing as usual. By the absence at the inner end of the bearing of the usual
curved or convex projecting part for bearing against and supporting the fillet or
curved shoulder of the neck of the roll, overheating at the fillet part of the neck of
the roll is wholly prevented and the tendency of the said neck to break or split at
the fillet is thereby prevented or reduced to a minimum and as less friction is
produced at the neck, a less quantity of lubricant is required as before stated.
The side and top bearings at the neck of the roll (not represented) are constructed
and applied in the manner described and represented with respect to a bottom
bearing, that is, each side and top bearing has at its inner or fillet end a curved or
angular recess which is situated under the fillet part of the neck of the roll.
The bottom, top and side bearings of the rolls are supported in the housings in
the ordinary way and are kept in position by the ordinary appliances which I do
not think it necessary either to describe or to represent.
Having now particularly described and ascertained the nature of my inven-
tion and the manner in which the same is to be performed I declare that I
claim as my invention of “A new or improved bearing for the necks of
rolls
"
The construction hereinbefore described and illustrated in the accompanying
drawing of the inner or fillet end of the neck bearings of rolls that is to say,
making in the said inner or fillet end of the bearing, a curved or angular recess
extending nearly from side to side of the said inner end so that the fillet or curved
shoulder of the neck of the roll does not come in contact at that part with the
bearing for the purposes and substantially as described and illustrated.
