PROVISIONAL SPECIFICATION.
Improvements in Machines for Mixing Concrete and similar
Substances.
I, JAMES STANSFIELD, of Todmorden, in the County of York, Asphalte Manufacturer,
do hereby declare the nature of this Invention to be as follows:-
I take a revolving circular pan or vessel, similar to that used in a mortar, or pug,
nill, and geared in a more or less similar manner to any suitable motive power.
Extending on each side from the framework, that supports the centre shaft of the
pan, or any other suitable fixed position, form or attach a rigid projection or bar,
to which are attached on each side the shaft in a suitable manner one or more plates
of steel or other suitable metal, formed and curved in a similar manner to a plough-
share. The revolution of the pan forces the concrete or other material against the
plates, which turn it over and mix it. The plates are arranged in different manners so
as to suit the substances mixed and thoroughly mix them.

COMPLETE SPECIFICATION.
Improvements in Machines for Mixing Concrete and similar
Substances.
I, JAMES STANSFIELD, of Todmorden, in the County of York, Asphalte 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:
It consists of a circular revolving pan or receptacle similar to that employed in an
ordinary pug or mortar mill and actuated in a similar manner, extending from the
central post or other fixed portion of which is a suitable bar or other projection to
which are attached blades or plates of metal bent in the form of a ploughshare, these
rest against the bottom of the pan and as it revolves the matter to be mixed against
them, they turn it over and thoroughly mix it.
may
It will be perceived that instead of using fixed plates and a revolving pan, I
reverse this and use plates revolving round a centre in a fixed pan. I may also
utilize an ordinary mortar or pug mill for this purpose by removing the rollers and
affixing my curved plates to the axles upon which they revolve; or use them in
combination with the rollers, by attaching them by a suitable projection to the central
post.
In order that the foregoing may be better understood, I send herewith a sheet of
Drawings in which :—
Fig. 1 shows an elevation, Fig. 2 a plan, and Fig. 3 a section in elevation of my
apparatus.
In all the Figs. a indicates the revolving pan, the projection, and c the curved
blades.

page_text: 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
1st. The combined apparatus, substantially as described and shown hereinbefore,
and in the accompanying drawing for the purpose sot-forth.
Dated this 16th day of November 1889.
