PROVISIONAL SPECIFICATION.
An Improved Egg-beater.
I, JOHN BROWN, of 3, Routledge Street, Tilery Road, Stockton-on-Tees, in the
County of Durham, Retired Merchant, do hereby declare the nature of this invention
to be as follows:-
My invention relates to egg beaters such as are used for beating eggs or other
semi-fluid or fluid substances, and consists of a vessel or utensil such as a metal tube
or the like receptacle which is provided internally at one or more intermediate
positions with a beater or masher composed of wire grating spaced rectangular
fashion or as a helical coil to allow the contents of eggs or similar substances to pass
through the meshes or grating thereof in the process of egg beating.
Hitherto it has been the practice in egg beating to employ in addition to the
vessel containing the egg pulp mechanical appliances or egg whisks operated by hand
or otherwise, which appliances do not thoroughly beat up and expand the contents
of eggs as desired.
The object of my invention is to construct an appliance which will more
completely beat up the contents of eggs and expand the mixture to the highest
degree by thoroughly intermixing the white and the yolk and aerating the mass in
much less time than the appliances at present in use, and also to dispense with any
mechanical action whatever in the egg beater or second instrument applied by hand,
the egg pulp being dashed through the meshes or grating of the beater instead of an
egg whisk or second instrument being employed for beating up the eggs.
In carrying out my invention I employ a small vessel such as a metal tube or tin
box fitted with a lid and of a diameter large enough to freely receive the contents
of one or more eggs at the open end; this vessel or receptacle is provided internally
at one or more intermediate positions with partitions consisting of wire grating or
helical coil extending the full area of the vessel so as to divide it into compartments,
the meshes or openings of the grating or coil being about of an inch or more
across to allow the contents of eggs to pass through in the process of egg beating.
In order to beat up eggs by my improved appliance the lid is taken off the
receptacle and the contents of the eggs discharged therein, and upon the lid being
replaced the receptacle is violently agitated or oscillated by hand which causes the
contents of the egg to be dashed to and fro through the meshes or wires of the said
partition until beaten up to the required consistency.

COMPLETE SPECIFICATION.
An Improved Egg-beater.
I, JOHN BROWN, of 3, Routledge Street, Tilery Road, Stockton-on-Tees, in the
County of Durham, Retired Merchant, 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 egg beaters for beating eggs, yeast and the like substances
which when thoroughly intermixed by agitation and aerated so as to expand to a
high degree and acquire a "body" or firm sponginess are employed in baking bread
and in similar processes.
Hitherto it has been the practice in egg beating to place the egg pulp in a vessel

page_text: in which it is beaten or whisked up by a whisk held in the hand or by mechanical
appliances of various kinds operated by hand or otherwise, and it is found in practice
that such mechanical or hand operated appliances do not so beat up and aerate the
mass or substance under treatment as to expand the mixture to the highest degree
and work it up to its best condition to be used for baking or the like processes.
The object of my invention is to construct an egg beater which will effect this
purpose more completely and in less time than the egg beaters at present in use, and
consists of a closed vessel or receptacle of cylindrical or rectangular form in which
the egg pulp or other substance is enclosed and in which is provided internally at
one or more intermediate positions with a wire grating spaced rectangular fashion
or as a helical coil through which the egg pulp or the like substance is dashed to
and fro by violently oscillating or shaking the beater in the hand. The motion of
the hand of the operator is thus directly imparted to the egg pulp or the like
substance under treatment without the intervention of mechanical action or a
separate instrument held in the hand.
And in order that my invention may be clearly understood and readily carried
into effect, I have appended a drawing to this Specification in which I illustrate
egg beaters constructed in convenient forms for effecting the purposes of my
invention.
In the drawing
Figures 1 and 2 are corresponding sectional views on lines x x and y y respectively
of an egg beater of a size to be grasped in the hand, whilst
Figures 3, 4, 5 and 6 relate to a larger sized beater to be oscillated or shaken by
hand upon a rocking frame of simple construction.
In Figures 1 and 2 the beater consists of two parts a and b fitted together at
their
open ends so as to form a closed vessel which is practically air tight. In the
part b is provided and fixed in position the wire grating e from which good results
are obtained when the bars d are set apart about half an inch.
For ordinary purposes six inches in length by two and a half inches in diameter
are found to be suitable dimensions for the casing.
It is not essential that the grating should have its bars arranged rectangular
fashion as shown more particularly in Figure 2, as a helical coil may be also used
with say a cross bar to stiffen it towards the centre.
The construction of this form of egg beater may also be modified in detail in the
following manner :-Instead of uniting two open ended casings together with the
wire grating fixed in position in one of them, as for instance in the part b, by which
arrangement the inside of the said part is only accessible through the bars of the
grating c for the purpose of cleaning unless the end 6₁ thereof is removable, the
casing may if preferred consist of one long tube closed at one end and with
the grating c fixed to the other end which is removable instead of to the inside of
the casing, the grating being supported therefrom at the proper distance by one
central or other suitably placed small rods extending from the said grating to points
of attachment in the end or cover so that when the end or cover is removed to open
the beater the grating is withdrawn with it, leaving the interior of the casing clear
of obstruction for the purpose of cleaning and charging with egg pulp or other
substance.
The ends may if preferred be roughened by indentations or stamped impressions
which assist in breaking up the egg pulp or like substance.
In Figures 3, 4 and 5 I have illustrated a larger form of my improved egg
beater, Figures 3 and 5 being side and end elevations respectively, and Figure 4 a
corresponding plan thereof.
The beater in this case consists of a rectangular box or receptacle e mounted on
a rocking frame f, the legs of which are brought to points to enter the surface of a
table or bench sufficiently to obtain the requisite leverage to rock the beater by
grasping the handles g; is the lid providing access to the inside of the beater for
cleaning and charging in the egg pulp or other substance, and & is the wire grating
shown in position inside the beater in Figure 5 and in detail in Figure 6; this

page_text: grating as is clearly shown in the figures is removable at will by means of the
button or knob l, and accurately fits into its place in the box e.
The uprights of the rocking frame fare received into sockets m in the manner
shown to enable the beater to be operated with a rocking frame as hereinbefore
described, namely by the oscillation of the hand of the operator, and by this mode
of mounting my improved beater on a rocking frame, 100 to 150 eggs may be
beaten or whisked up together.
In using beaters as constructed according to this Specification, for beating eggs
the eggs are first charged into the vessel or box which is then closed up and
shaken for 7 or 8 seconds, the vessel is then discharged of its contents and is then
rinsed out with either milk or water which can be added to the beaten eggs,
and afterwards with water alone, after which it may be set up to drain for
further use.
For yeast beating, the yeast should be covered with water when placed in the
tin, which is then closed up and shaken for 5 or 6 seconds when the mixture attains
the requisite condition for making bread very light.
In conclusion I observe that I do not limit my invention to the precise means
referred to in the Specification and accompanying drawing, so long as the essential
feature of dashing the egg pulp or other material under treatment through a wire
grating or its equivalent within a closed. vessel or receptacle is retained, as the
modifications hereinbefore described and illustrated are given as examples of a con-
venient way of carrying my invention into effect, but which may be varied to the
sizes, forms and details of construction which best commend themselves for the
particular purposes in view.
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 egg beater consisting of a closed vessel or receptacle of cylindrical, rectangular,
or other suitable form which is provided internally at one or more positions with a
wire grating or its equivalent through which the egg pulp or other substance is
dashed to and fro, substantially as and for the purpose as hereinbefore described and
illustrated by way of example in the accompanying drawing.
