Improvements in Bearings for Shafts, Rollers, or other Revolving
Surfaces.
DAVID PERFITT GRIFFITHS MATTHEWS Laburnum House Cardiff Road
Newport, Monmouthshire Engineer & Brass Founder do hereby declare the
nature of this invention to be as follows :—
This invention has for its object improvements in the sections of bearings made
of metal or metals and in one or more pieces and having water chamber, or
chambers, formed by a core or cores in the moulding operation of the same in the
body of the bearings and situated within or between the base and revolving surface
of the bearings and which may be used with or without water according to circum-
stances and application of the bearings, the water when required may be conveyed
from any supply tank by pipes or other suitable means to the working place of the
said bearings and connected to the water inlet pipe or other suitable fitting attached
to the bearings or the same may be in the solid of the bearing at any most con-
venient point, the improvements will also consist of a water outlet from a suitable
part of the bearing and the outlet water conveyed by pipe or other means to the
other adjacent rollers of the mill from one bearing to the other, or I make the
outlet water to empty itself on the wobble (or spindle connection) of the rollers to
assist or add to the effect of the water passing through the bearings for keeping the
revolving surfaces cold when in work thereby reducing friction, wear and tear of
all revolving surfaces, connections, together with the bearings and other parts from
the mill to the engine, and when the bearings are made with chambers to contain
water I connect one chamber with the other by a passage or passages so that the
same water shall pass from one chamber to the other when in use and to leave the
bearing at the outlet connection.

Improvements in Bearings for Shafts, Rollers, or other Revolving
Surfaces.
I, DAVID PERFITT GRIFFITHS MATTHEWS of Laburnum House, Cardiff
Road, Newport in the County of Monmouth Brass Founder and 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:
This invention has for its object improvements in the sections of bearings made
of metal or metals and in one or more pieces and having a water chamber or water
chainbers formed by a core or cores inserted in the moulds in which such bearings
are cast.
I make the cavities in the body of the bearings and situated within or between
the base and the hollow which confines the shaft or other revolving surface. These
cavities may be used as water ways for cooling by circulation of water if required
in which case I provide inlet and outlet connections communicating with the
cavities and capable of being connected by means of pipes in a manner to establish
a flow of water separately for each bearing or a continuous flow through all the
bearings of a machine. The supply of water is conveyed by pipes from one bearing

page_text: to another the outlet connection of the first being joined by a pipe with the inlet
connection of another; or in case of a separate How for each bearing the outlet
pipe may be arranged so as to deliver the overflow of water upon the wobble or
spindle connection of the rolls to assist in keeping the bearing cool.
The accompanying drawing illustrates my invention as applied to a pair of tin
plate rolls as at present used for rolling hot plates:
-
Figure 1 is a front view of a pair of tin plate rolls.
Figure 2' is an end view of the same.
Figures 3, 4 and 5 are enlarged detail views of various forms of the bearings
made in accordance with this invention.
A is the main water pipe having an elastic or india rubber junction piece B to
compensate for the rise and fall of the top roll in the operation of rolling plates.
Crepresents the upper bearing in which cavities are formed through which the
water supplied through the pipe A. flows to the outlet D which is connected by the
flexible pipe E with the side chuck F. The side chuck F is formed with an
internal cavity through which the water circulates and from which is passes out by
the pipe G to the side chuck. H of the lower roll K: From the side chuck H the
water is conducted by the outlet L to the lower bearing M the outlet connection
from which has a pipe N attached thereto to convey the water to any convenient
point at which it may run to waste, or to the next pair of rolls.
The main water pipe A may be carried across the standard of the rolls and feed
the bearings and side chucks at the opposite ends of the rolls and K in the same
manner as that herein before described with reference to the side of the rolls shown
in the drawings.
In order that the different sections of the improved bearings and their construc-
tion shall be more plainly understood and to meet the various necessities I show
them in detail as used in the application of water and without water.
Figure 3 is a detail view of the bearing M and side chucks F, H shown in
Figure 2 showing the water space in dotted lines together with the inlet P and the
outlet R. L' is a hole for receiving the tubular lever or an elbow Lishown in
Figure 2' for the water inlet. N¹ is a hole for receiving a similar fitting N for the
water outlet. The end view of the bearing M is drawn onethalf in section and the
other half in elevation. O is one of the water chambers or spaces in- 'which
the water enters and from which it passes to the other chamber keeping both con-
stantly full of water for hot plate rolling or the same or similar section may be
used without the application of water. S represents part of the journal or roll-
neck.
-
Figure 4 shows, half in section and half in elevation, a modification of the
bearing M made in parts in different metals. Q is the brass or any other suitable
metal cast upon the seating M which may be made of cast iron, cast steel: or
malleable cast iron. Land Nare the holes for the water inlet and water outlet
connections respectively, O the water chambers or spaces. This arrangement may
be used for cold rolls or for hot rolls and with water or witliout it.. K represents in
part the journal or roll-neck. The seating M may be made solid or cored. .to
produce water chambers or spaces as shown.
Figure 5 shows half in section and' half in elevation another modification of the
bearing M made of brass or of any other suitable metal. S are the Hollow spaces
made to economise metal and T are the strengthening ribs. This arrangement is
intended for cold journals. K represents in part the journal or roll-neck.
Having now particularly described and ascertained the nature of my said-inven-
tion and in what manner the same is to be performed. I declare that what I
claim is :-
Bearings for shafts, rollers or other revolving surfaces having open or internal
cavities, the internal cavities having inlet and outlet connections communicating
therewith by means of which pipes may be coupled' thereto to maintain a flow of

page_text: water through a bearing or through a system of bearings of a machine in cases
where water is needed, and in the absence of water, water not being needed, open
cavities substantially as herein described and illustrated by the accompanying
drawings.
