IMPROVEMENTS IN BEARINGS OR BRASSES FOR ROLLING MILLS
Year: 1885

page_text: COMPLETE SPECIFICATION,
I WILLIAM EDWIN HARRIS of the city of Saint Louis, in the State of Missouri
one of the United States of North America, Sheet and Tin Plate Roller do hereby
declare the nature of my said Invention for IMPROVEMENTS IN BEARINGS OR
BRASSES FOR ROLLING MILLS, and in what manner the same is to be performed to
be particularly described and ascertained in and by the following statement:-
The following is a full clear and exact description of my Invention reference
being had to the accompanying drawings in which :-
Figure 1 is an end view of a pair of rolls with my Improvements applied.
Figures 2, 3, 4, 5, 6, 7 and 8 are diagrams illustrating my Invention in different
forms and on bearings or brasses of different shapes.
My invention relates to a means of keeping the brasses or bearings of rolling
mills from becoming heated and my invention consists in features of novelty
hereinafter fully described and pointed out in the claims.
Referring to the drawings, A represents one end of a frame of a pair of rolls for
rolling metal, and B the rolls. C represents the top and bottom brasses or bearings
and D the side brasses or bearings.
Heretofore great difficulty has been experienced in attempting to keep these
brasses or bearings from becoming over heated by the hot metal passed between
the rolls which causes them to wear away quickly and to break before they are
worn out. To keep them cool it has long been the practice to discharge cold water
on to the journals of the rollers but this is wholly insufficient and unsatisfactory
and besides with this method the grease is washed from the journals and wasted
in large quantities.
My improved method consists in causing a circulation of water through the
brasses or bearings preferably by casting grooves or recesses O in them to receive
water pipes I, see Figures 2, 3 and 4 or the brasses or bearings may be cast around
the pipes as shown in Figures 5, 6 and 7. The pipes may all connect with a single
supply pipe J see Figure 1 and the water, after circulating through them may be
discharged on to the ground.
In figures 2 and 6 ordinary bearings or brasses are shown-the recess being
shown in Figure 2 and the brass being cast around the pipe in Figure 6. In
Figures 3 and 7 brasses with strengthening central projections are shown and in
Figures 4 and 5 side brasses are shown.
In Figure S two pipes are shown in one brass which may be used when desired.

page_text: By my improved means the water is carried into the body of the brasses where
it will do the most good and does not come in contact with the journals washing
off the grease and depositing lime that injurious to the journals and brasses,
causing them to wear away quickly.
My invention is applicable to all kinds of rolling mills, such as sheet iron mills,
steel mills, tin plate mills, copper plate mills, guide mills, and to wire and other
mills.
The bearings may be made of brass (from which the well known term of
"brasses" is derived) or they may be made of bronze, Babbitt or other metal.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. The method herein described for cooling the brasses or bearings of rolling
mills consisting in causing a circulating of water through the body of the brasses
or bearings, substantially as set forth.
2. The combination of the brass or bearing of a rolling mill and a pipe located
in the body of the brass or bearing substantially as and for the purpose set forth.
3. In combination with a brass or bearing of a rolling mill having a recess or
groove, a pipe located in said recess for the purpose set forth.
