COMPLETE SPECIFICATION.
A New or Improved Construction of Apparatus for Use in the Making
of Emulsions.
I, GEORGE JAMES BLORE, of 281, Broad Street, Pendleton, Manchester, in the
County of Lancaster, Chemist and Optician, 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 has for its object to provide simple and effective apparatus for
use in the making of emulsions and for use more particularly by manufacturing
chemists, or in wholesale establishments where large quantities of emulsions
are required although when made in small sizes available also for druggists
and chemists generally, or in hospitals for making small quantities.
The accompanying drawings illustrate the salient features of my invention
Fig. 1 being an exterior elevation and Fig. 2 a vertical section of the improved
apparatus, whilst Fig. 3 is a plan of an essential part.
According to my invention I employ a cylinder or casing (A) made in cast iron,
or other material suitable for the purpose and adapted by preference to stand
vertically on a floor, table, bench or counter.
This cylinder I provide with a lid or cover (B) and through the said lid and
by preference through a packed gland (B*) I pass a piston rod (C), one end of
which carries a piston or dasher (D) within the cylinder, and the other the
cross-handle (E) outside the cylinder. Within the said cylinder (A) I fit a
cylindrical lining (F) of by preference sheet metal, the inner face of which
is enamelled or tinned. The dasher or piston (D) is dished out, as shewn, and
provided with holes (D) and the floor of the cylinder (A) and the lining (F)
are convex in keeping with the curvature of the piston to allow the piston or
dasher to travel the full depth of the cylinder.
The use and action of the apparatus is as follows:-The lid (B) being first
removed by the handles (B) the liquid to be emulsified and the emulsifier are
poured into the cylinder in the proper quantities. The lid (B) is then replaced,
and by its weight and tightness of fit. or other means, securely held on the
cylinder. The handle (E) is then taken hold of and worked rapidly up and down,
thereby causing the dasher or piston (D) which is loose fitting, to break up,
agitate or mix the liquids and by continued action effect a thorough emulsion.
This action is largely brought about by the holes (D) in the piston which
repeatedly divide or break up the liquids, also by the curved shape of the dasher
which tends to collect the liquid and induce it to gather towards the centre of the
dasher and thus bring it under the direct thrust of the piston rod.
The operator can tell when the emulsion is completed by the increased
resistance of the liquid to the action of the piston, and, by repeated use of the
apparatus, the operator soon learns to judge of the exact amount of agitation
required.
When fully emulsified further quantities may be added, or that which is ready
for use be removed from the cylinder, either by tilting the cylinder or removing

page_text: the lining (F) which is formed (by preference) with pouring lips (F³) which
also serve as handles for facilitating the withdrawal of the lining.
In lieu of the loose lining I may enamel or tin the interior of the cylinder,
or form the cylinder of porcelain or like material which will in no way con-
taminate the liquids to be treated.
To facilitate filling without removing the lid I may provide such lid with a hole
and funnel, as shewn by dotted lines in Fig. 2, and for withdrawal purposes
may fit the lower end of the cylinder and lining with a tap or spout, but I prefer
the withdrawal to be effected as aforesaid. Although preferring the piston to be
of concave formation, it may be flat, and in lieu of being worked by hand it may
be operated by motive power;
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:-
1:In apparatus for emulsifying purposes, the combination and arrangement
of parts, substantially as herein set forth and illustrated on the accompanying
drawings,
2: In apparatus of the kind indicated, a perforated and curved dasher or
piston, as set forth.
3: In apparatus of the kind described, a cylinder with an enamelled, tinned
or like lining, as set forth.
Dated this 24th day of November 1899.
GEORGE JAMES BLORE.
