An Improved Roller Bearing for Cement and Mortar Mills.
We, CHARLES JAMES WILLIAMS, 86, Annandale Road, East Greenwich, in
the County of Kent, Engineer, and JABEZ HOLLICK, 3 Coleraine Road Blackheath,
in the County Kent, Cement Manufacturer, 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 refers to horizontal bearings for the shafts or spindles of
machinery, such as mills for grinding mortar and cement.
It consists of a series of rollers arranged annular fashion around a shaft or
spindle, and between the said shaft and the centre hole of the edge runner. These
rollers may be journalled in a flange formed on the edge-runner or may run in
suitable grooves formed in a separate enclosing box or bush as hereafter described.
If not fitted in a box the rollers could be kept in place by flanged collars or
otherwise.
If fitted in a box, the box after inserting the rollers would be drawn tightly
inside the runner.
The box is cylindrical or of any form to suit aperture of runner and one end is
solid with a channel or groove to receive the end of the rollers. The other end of
the roliers fit in a similar bearing formed by a loose end piece which is fitted in the
end of the box to receive it.
We will now describe the invention with reference to the accompanying drawings
in which:
Fig. 1 is a side elevation partly in section of a bearing fitted into the centre of
an edge-runner as used in mills.
Fig. 2. shows a transverse section of Fig. 1.
a is the runner, into the central bore of which, is inserted the box b, at one end
of which is formed, a neck c, which supports pins d', of the rollers d. The pins at

page_text: the other end of the rollers rest upon a similar neck e formed on a loose grooved
flange or cover plate, fitted in the box b. The cover fis secured from rotating
independently by screwed studs g. h is the shaft.
The shaft, rollers and box are all preferably formed of steel but other suitable
materials may be used.
The method of fitting the spindle or shaft to the bearing is obvious. The
cylindrical bush is fixed in the hole in the centre of the edge runners with the
rollers inside and the loose end is screwed on, and the shaft may then be inserted
therein.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
An improved roller bearing for cement and mortar mills and the like, consisting
of the rollers d, d, with or without the bush b, with necks c, e, and the cover
plate f, or said rollers may be held in place by collars or flanges, as herein described
and set forth.
