Improvements in Bearings for Shafts.
I ARTHUR MAURICE ROBINSON of Railway Works Rochdale, in the County
of Lancaster, Engineer, do hereby declare the nature of this invention to be ns.
follows:-
The invention relates more especially to bearings for use with roller mills where
it is essential that oil should be prevented from escaping from the said bearings
and contaminating the flour, and when it is desirable that the shafts should be
readily removable from the bearings when required.
For the above purpose I make use of a bush which I fit within a container
having ways for the supply and circulation of lubricant and retaining guards for
the said lubricant, and I combine such compound bearing with a pedestal bracket or
frame by means of seats in such manner that the said compound bearing and.
pedestal bracket or frame will when held together by bolts or securing agents form
a rigid structure easily separable on removal of the bolts or securing agents..
The shafts are provided with the usual collars for raising the oil from the bottom
to the top of the bearing and with the usual drip guards to prevent creeping of
the oil along the shaft.
The bush is fitted within the container so that it can be turned on its axis to.
bring different parts into wear.

1, ARTHUR MAURICE ROBINSON of Railway Works, Rochdale, in the County
of Lancaster, 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 :-

The shafts are provided with the usual collars for raising the oil from the bottom to-

DESCRIPTION OF THE DRAWINGS.
Figs. 1 and 2 are vertical sections at right angles to each other of a bearing
constructed according to my invention. a. is a bush surrounding the shaft b. say of
a roll in a roller mill. c. is a container within which the bush a. fits so that such
bush can be turned round as it wears. d. is a set screw for securing the bush in
position. e is a channel or way in the container by means of which lubricant can
be supplied to the bush and shaft through openings f. g. is a channel or way
which receives the surplus lubricant from the bush; and is a collar or disc on the
shaft. for raising the lubricant from the channel y. to the channel e for re-use.
e is a cover for the channel e. i are guards for retaining the lubricant within the
container. j. are the usual drip guards on the shatt to prevent creeping of the
lubricant. k. is a pedestal bracket to which the container is secured by seats or
lugs and bolts in such a manner that such container with its bush and the pedestal
bracket form a rigid structure. The bracket. k. may be attached to or form part
of an arm m as shown, or it may be free to slide in guides, when the bearing is
used for a movable roll, or such bracket may be attached directly to, or form part
of, the main frame of the machine when the bearing is used for a fixed roll. By
releasing the bolts / the container and bush are rendily removed from the shaft when
required.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed 1 declare that what I
claim is :-
First. The combination in a bearing, of a pedestal bracket or frame, and a
container having a bush, lubricant retaining guards, and supply and circulation
ways, substantially as and for the purposes set forth.
Second. The coinbination of a bracket or frame and container as above described
secured together by means of seats or lugs and bolts or other securing ngents
substantially as and for the purposes set forth.
