MARTIN POTT BAILLIE, Baker and Confectioner, 8, Wilton Place, Hawick,
Scotland. I do hereby declare the nature of this invention to be as follows:-
An oval shaped vessel, composed of two compartments, an upper, and a lower
one. The lower compartment is for the purpose of holding hot water. The
upper compartment is the egg holder. This compartment has a concave oval
bottom. A horizontal spindle runs through the centre and on this spindle are
fixed a number of beaters. The spindle with beaters attached is made to revolve
by gearing which is fixed to the outside of the vessel. The mode of fixing the
spindle (which is movable) is by a square hole formed in one end which slips on
to the square end of the gearing spindle. The other end is fixed in the same
manner by an adjustable screw which enters from the outside of the vessel
opposite the gearing & enters a hole on spindle.

Improved Egg Whisk.
I, MARTIN POTT BAILLIE, of Teviot Vale Bakery, Wilkin Place, Hawick, in
the County of Roxburgh, Baker and Confectioner, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
This invention relates to improvements in the construction of egg whisks.
Constructed according to this invention the egg whisk comprises a vessel of
oval cross-section provided with an upper and lower compartment. The upper
compartment or egg holder, has a concave bottom, and arranged horizontally
across the compartment is a spindle carrying a number of beaters projecting
radially from it. The spindle with the beaters attached to it is made to revolve
by means of gear outside the vessel and is so mounted that it may easily be
removed from the compartment or replaced within the same.
In the accompanying drawings which illustrate an egg whisk constructed
according to this invention
Figure 1 is a side elevation and
Figure 2 an end elevation, portions being broken away in both figures for the
sake of clearness,
Figure 3 being a plan with the top cover removed.
Like letters indicate like parts throughout the drawings.
The vessel A. (Figs. 1 and 2)
of oval cross section and is provided with a
false bottom or diaphragm B which divides it into an upper chamber or compart-
ment B and a lower chamber or compartiment B2; the diaphragm B is concave

page_text: on that side which faces, the compartment B₁. Across the centre of the com-
partment is mounted a spindle provided with radial blades or beaters C'.
The spindle C together with the radial blades or beaters C¹ can be rapidly re-
volved by means of gear wheels D 1 mounted in a frame 12 upon the outside
of the vessel A and driven by means of a handle D³. The blades C are pre-
ferably constructed of wire bent into the outline of a screw propeller and their
extremities travel within a short distance of the concave bottom or diaphragm B
In the accompanying drawings the spindle C is shown as having three sets of
these blades or beaters, C each set comprising four separate blades.
The blades of the set at one end of the spindle C and of the centre set are
arranged to drive any liquid, in which they may be made to revolve, in one
direction, whilst those of the remaining set are arranged to drive any such liquid
in the opposite direction. The object of this arrangement is to increase the
agitation of the matter it is desired to beat and at the same time to maintain
a main flow in one direction by means of the two sets of blades acting in oppo-
sition to the one set.
The sets of beaters at the ends of the shaft C are shown in the accompanying
drawings as slightly curved towards the centre set, but the arrangement of the
sets in relation to one another, the number of sets employed and the number of
individual blades used to compose each set may be varied, without departure
from this invention.
To enable the easy removal of the spindle C together with its blades C¹ for
the purpose of cleaning, it is provided at one end with a square recess E by
which it engages with, and is held in postion on, the square ended spindle of
the gear wheel D, the square end of the spindle protruding into the interior of
the vessel A. The other end of the spindle C is held in position by, and runs
upon, a set screw F which also projects into the interior of the vessel A and is
provided with a lock nut F.
The operation is as follows:--
The eggs to be beaten are placed within the compartment 131 (the top of
which may be provided with a lid B) and the compartment B2 may be filled
with hot water. The handle 103 is then turned causing the blades C to revolve
rapidly whilst the concave shape of the diaphragm or bottom B tends con-
tinually to bring the eggs under the immediate action of the blades.
When it is required to clean the compartment B or the spindle C and
blades C¹ the lock-nut F is loosened and the screw withdrawn; the spindle C
being then free may be lifted out. The operation is reversed to replace the
spindle in its operative position within the compartment B.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is:
1. An egg whisk having a casing of oval cross section provided with a con-
cave bottom such as B substantially as described.
2. In an egg whisk of the kind described the combination with a shaft C of
wire beaters of skeleton helical form so arranged thereon as to give an opposing
flow substantially as described.
3. The complete egg whisk substantially as described and illustrated in the
accompanying drawings.
That this and love of November 1898
