page_text: I, RICHARD HAMMERSLEY HEENAN of Newton Heath Iron Works, Manchester 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:-
My invention relates to improved apparatus for stirring mixing or incorporating
liquid or pulverulent substances contained in flat pans or receptacles.
According to my invention I provide a circular pan with a fixed central tubular
pillar, the upper end of which carries a bevil toothed ring. Through this pillar passes
a vertical shaft rotated by suitable gearing, and which is provided above the top of the
pillar with one or more radial arms carrying a horizontal shaft. On this horizontal
shaft is, firstly, a bevil pinion in gear with the said toothed ring, and secondly one or
more other bevil pinions gearing with bevil pinions on vertical spindles carried by the
said arm or arms, which spindles carry stirrers of any desired form that extend down to
the bottom of the pan.
From this arrangement it will be seen that as the arm is carried round by the
central vertical shaft, the horizontal shaft will be made to rotate by reason of its
pinion gearing with fixed toothed ring, and will be made to impart such rotation to
the spindles of the stirrers, which are at the same time carried round the pan by the
arm or arms.
Fig. 1 of the accompanying drawings shews a side elevation and Fig. 2 shews a
plan of one arrangement of my improved mixing or stirring apparatus operating as
above described.
The pan A, which may be heated by a steam or hot water jacket as shewn, has a
central tubular pillar B through which passes the vertical shaft Û having fixed on its
upper end an arm D carrying first a horizontal shaft E and secondly the two vertical
spindles F F of stirrers F. The shaft E has a bevil pinion G which gears with a
bevil toothed ring H fixed on the pillar B and it has two bevil pinions II gearing
with bevil pinions on the spindles of the stirrers F F. Thus as the shaft C is
rotated by means of suitable driving gear from the mill shaft K, it carries round the
arm D with the stirrers F in the pan, while at the same time the stirrers will receive a
rotary motion from the shaft E which is rotated by its pinion G gearing with the
toothed ring H.

page_text: It will be evident that the shaft C instead of passing up through the pillar B, may
pass down from an overhead motion, and merely take a bearing in the. pillar. Also,
in place of a single arm D there may be two or more arms, with horizontal shafts and
stirrers, and there may be any desired number of stirrers along the shaft, which may
.be of any other desired form, such as the arrangement of stirrers with concentric
spindles used for egg-beaters and the like.
The arm D. may be provided with a scraper at D' for scraping round the side of
the pan.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what
1 claim is
In apparatus for stirring incorporating or mixing substances, the use in combina-
tion with a pan having a central vertical shaft, of a revolving arm carrying a hori
zontal shaft for imparting motion to one or more stirring apparatus also carried by
the said arm, which shaft has a bevil pinion gearing with a fixed bevil toothed ring on
a central support in the pan, so that as the shaft is carried round by the arm it
receives rotary motion from the toothed ring, and imparts such motion to the stirrer
or stirrers substantially as herein described.
