PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Grinding Cement or other
Substances.
1, THOMAS WILLIAM BRITTAIN of London Road, Chesterton in the County of
Stafford, Ironfounder, and HENRY JAMES RALPH PAMPHILON of 19 Moody
Terrace, Congleton, Cheshire Gentleman do hereby declare the nature of this
invention to be as follows:-
This invention relates to apparatus of the centrifugal type adapted for grinding
cement or other substances.
According to the present invention, upon the internal shaft are mounted one or a
series of boxes or slides adapted to receive and carry the movable grinders which
are capable of radial movement therein with relation to the shaft. It follows from
this construction that if the shaft is caused to revolve the movable grinders will by
the action of centrifugal force be thrown out and bear against the internal face of
the grinding cylinder. It is generally preferable to mount a series of boxes or
holders on the shaft at varying angles between the vertical and horizontal lines of
the machine, and it will of course be evident that the material of which the
grinding faces are formed should be such that the material under treatment will
not be injured thereby, and also that the movable grinding faces may be rounded
or formed at an angle depending upon the nature of the face against which they are
intended to work. Suitable feed and discharge openings are provided.
Dated this 9th day of May 1892.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Grinding Cement or other
Substances.
We, THOMAS WILLIAM BRITTAIN of London Road, Chesterton in the County
of Stafford, Ironfounder, and HENRY JAMES RALPH PAMPHILON of 19 Moody
Terrace, Congleton, Cheshire, Gentleman, 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 relates to apparatus of the centrifugal type adapted for grinding
cement or other substances.
In order that the invention may be clearly understood reference is made to the
accompanying drawings in which :-
Fig. 1 is a longitudinal sectional elevation, and Fig. 2 an elevation on line xx
of so much of the apparatus as is necessary to illustrate the present invention.
According to the present invention, upon the internal shaft a which may be
squared for that purpose, are mounted one or a series of boxes or slides b adapted
to receive and carry the movable grinders c which are capable of radial movement
therein with relation to the shaft. It follows from this construction that if the
shaft is caused to revolve the movable grinders will by the action of centrifugal
force be thrown out and bear against the internal face of the grinding cylinder d.
It is generally preferable to mount a series of boxes or holders on the shaft at
varying angles between the vertical and horizontal lines of the machine, and it will
of course be evident that the material of which the grinding faces are formed
should be such that the material under treatment will not be injured thereby, and
וגמ

page_text: also that the movable grinding faces may be rounded or formed at an angle
depending upon the nature of the face against which they are intended to work.
Suitable feed and discharge openings are provided.
It is of course not, broadly speaking, new to employ centrifugal force in grinding
and crushing machines, as will be seen for example by referring to Specification
No. 9205 of 1891, but―
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:
:-
The improved annaratus for crinding cament
