PROVISIONAL SPECIFICATION.
Improvements in Apparatus to be used for Beating, Mixing,, or
Whipping Cream, Eggs, and similar Liquid or Semi-liquid
Substances.
I, JOHN WILLIAMS, of St. Luke's Road, Pontnewynydd, near Pontypool, in the
County of Monmouth, Grocer, do hereby declare the nature of this invention to be
as follows:-
The object of this invention is to produce a cheap and simple apparatus for
beating, mixing, or whipping cream, eggs and similar viscous liquid or semi-liquid
substances, by means of which a good stiff froth is formed in a short time by a
simple up and down motion of part of the said apparatus.
The invention consists of a wire spiral stem and reciprocating nut in the form of
an Archimedean drill, on to the bottom of which is formed or affixed a wire frame
consisting of two or more radial wings or beaters. These beaters are rotated by
the reciprocation of the nut.

COMPLETE SPECIFICATION.
Improvements in Apparatus to be used for Beating, Mixing, or
Whipping Cream, Eggs, and similar Liquid or Semi-liquid
Substances.
I, JOHN WILLIAMS, of St. Luke's Road, Pontnewynydd, near Pontypool, in the
County of Monmouth, Grocer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :--
The object of this invention is to produce a cheap and simple apparatus for
beating, mixing, or whipping cream, eggs and similar viscous liquid or semi-liquid
substances, by means of which a good stiff froth is formed in a short time by a
simple up and down motion of part of the said apparatus.
The invention consists of a wire spiral stem and reciprocating nut in the form of
an Archimedean drill, on to the bottom of which is formed or affixed a wire frame
consisting of two or more radial wings or beaters. These beaters are rotated by
the reciprocation of the nut.
In the accompanying drawings Figure 1 shews elevation and inverted plan
of one form of my invention, having two radial beaters and Figure 2 shews
similar views of another form having four beaters, but I do not confine myself to
the number or shape of the radial beaters shewn. I prefer to make the stem A of
twisted pinion wire as shewn, as this is a cheap and simple form of construction,
but it may be made with a core having steep spirals thereon. The nut B is provided
with internal spiral grooves, corresponding to the spirals or threads on the stem A,
and if desired may be furnished with a handle for easy manipulation. The nut is
reciprocated on the stem thus producing rotary reciprocal motion of the latter. The
end of the stem A rotates in the boss C of the handle D.
The wings or beaters E are fixed to an elongation F of the stem and are arranged
radially on the said stem A, and are made as an open wire framework of any
suitable pattern or design. A series of wire concentric rings as shewn preferred
LD

page_text: on account of the ease with which it can be manufactured and its strength when
made. It is of course essential that the beaters should be made as open frames to
allow the liquid and semi-liquid to pass between the wires e.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
An apparatus for beating, mixing, or whipping cream, eggs, and similar liquid or
semi-liquid substances, consisting of a spiral or threaded stem A and reciprocating
nut B with two or more radial open frames wings or beaters E attached to the
stem or to an extension thereof, all combined and operating substantially as and for
the purpose hereinbefore set forth and illustrated in the accompanying drawings.
