I WILLIAM ROBERT LAKE of the firm of Haseltine Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex do hereby declare the nature of
this invention to be as follows:-
My improvement relates to beaters for beating eggs and other semi fluid or fluid
substances, and it consists in certain novel constructions and combinations of parts
substantially as hereinafter described.
The frame of the beater has at its upper end a loop for holding the beater by.
Projecting from the lower end (when the beater is held in position for operation)
of the frame is a shaft or rod firmly fixed therein. This shaft is provided with a
button at its lower end, which facilitates its resting upon the bottom of the dish
containing the eggs or the like and serves as a check to prevent the beater from
escaping off of the rod, at its part which is coiled loosely around the same, as
hereinafter described.
"
The beater proper consists of a wire in the form of coils wrapped around the said
rod just above the button at one end so as to be capable of sliding freely up and down
on said wire, and thence carried outward in a succession of coils continually larger
in size until it reaches and forms the outer and widest coil. Thence it is again coiled
inward in a helical shape by constantly narrowing the coils until it comes underneath
the frame when it is bent so as to pass straight upward through a hole in the frame in
the form of a rod which at its upper cnd has attached to it a roller revolving on a
portion of the rod bent at right angles to it. This roller may, however, have its axis,
on which it revolves, attached to the rod in any other convenient form. Where the
roller carrying rod passes through the frame, it fits so as to slide up and down freely
through the same.

page_text: Upon a pivot fixed in the frame a wheel is made to revolve, and is provided with a
handle by which it can be turned. The rear face of this wheel has a cam groove in
it, into which the roller fits, so as to force its rod to reciprocate up and down as the
wheel is revolved and the roller follows the groove. The roller may be omitted and
the pivot on which it turns can be fitted directly to a groove if desired, as its function
is merely to save friction.
It will be seen that the reciprocation of the roller carrying rod continually
reciprocates the convolutions of the upper coil through itself and the outer coil,
and it also reciprocates the convolutions of the lower coil through themselves and the
outer coil, because it is found in practice that the central part of the lower coil
continually vibrates up and down on the main rod above the button as the wheel is
revolved. The vertically opposite turus of the upper and lower coils also continually
vibrate towards and away from each other and act in opposition to each other in
beating up the egg or the liko. The vibration of the outer coil also assists the
operation. By thus using two coils jointed at their outer circumference in the ring
or coil I therefore obtain a fourfold operation of them past and against their several
parts. By having the roller carrying rod reciprocate up and down in a right line I
obviate any necessity of having the upper coil slide on the main rod and its consequent
friction and also prevent any twisting or bending of the wire of the rod or coils
such as would occur if the rod was connected eccentrically to a crank or disc, and
I prevent any abrasion of the hands of the user from the presence of the teeth on
the wheel.
As the wire coils are yielding and elastic all round the central or main rod they
cannot be bent out of shape or broken as if they were connected to the rod by any
rigid fastening, and their durability is increased thereby.
It will be observed that this beater will fit into the bottom of a round or flat bowl
or dish equally well, as it has the capacity to accommodate the movements of its coils
to either, without injury or impairing its operation.
It is not absolutely essential to the operation of the beater part of my device that
both coils shall be of helical form, although I consider that construction preferablo,
for while one of said coils is helical the other may be in the same plane throughout,
and they will continue to vibrate in opposition to each other as described: or both
coils may be made in separate planes connected by the outer coil and drawn apart and
together by the roller carrying rod by connecting the inner end of a coil to the
central rod. I do not however prefer the latter construction as it interferes with the
secondary vibrations communicated to the coil which produce its constant movement
at the centre upon the central rod as described, even while it retains the principle of
opposing the movement of the coils to each other which is the main feature of the
invention.
The beater may be operated as described by removing the wheel and reciprocating
the roller carrying rod by hand. The coils and rod may also be removed from the
frame and be used as an egg-beater, by simply reciprocating the double coil up and
down in the receptacle containing the eggs the same action of the coils against and
upon each other being produced.

page_text: I, WILLIAM ROBERT LAKE, of the firm of Haseltine and Lake Co., Patent Agonis
Southampton Buildings in the County of Middlesex 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 beaters for beating eggs and other semi-fluid or fluid
substances, and it comprises certain new and useful constructions and combinations of
parts thereof, substantially as hereinafter described.
In the accompanying Drawing
Figure 1 is a rear side view of a beater, constructed according to my invention,
with a portion of the frame broken away to show the construction of the parts.
Figure 2 is a side elevation of the same taken at right angles to Figure 1, with
portions of the frame and operating mechanism in section.
A is the frame of the beater which has at its upper end a loop A' for holding the
beater by.
Projecting from the lower end (when the beater is held in position for operation)
of frame A is a shaft or rod a, firmly fixed therein. This shaft is provided with a
button a¹ at its lower end, which rests upon the bottom of the dish containing the
eggs or the like and serves as a stop to prevent the beater from coming off the rod,
at its part which is coiled loosely around the same, as hereinafter described.
The beater proper consists of a wire bent in the form of coils c and encircling the
rod a just above the button a¹ at one end, so as to be capable of sliding freely up and
down on said wire, and thence carried outward in a succession of the coils c, continually
increasing in size, until it reaches and forms the outer and widest coil c', and thence
it is again coiled inward in a helical shape by constantly decreasing the coils c², until
it comes underneath the frame A, when it is bent so as to pass straight upward
through a hole in the frame in the form of a rod c³, which at its upper end has
attached to it the roller c', and revolving on a portion of the rod c bent at right
angles to it. This roller may, however, have its axis, on which it revolves attached to..
the rod in any other convenient manner. Where the rod c³ passes through the
frame, it fits so as to slide up and down freely through the same.
Upon the pivot b fixed in the frame A, a wheel W is fitted to revolve and is provided
with a handle w, by which it can be turned. The rear face of this wheel has a cam
groove e formed therein into which the roller c' fits, so as to cause the rod c to move
up and down as the wheel W is revolved and as the roller follows the groove. The

page_text: roller c¹ may be omitted and the pivot on which it turns may be fitted directly into
the groove e if desired, as its object is merely to save friction.
It will be seen that the reciprocation of the rod continually reciprocates the
convolutions of the upper conical coil through itself and the outer coil c¹, and it
also reciprocates the turns of the lower coil c through themselves and the outer coil,
because it is found in practice that the central part of the lower coil continually
vibrates up and down on the rod a above the button a' as the wheel W is revolved.
The vertically opposite turns of the upper and lower coils and c also continually
vibrate towards and away from each other and act in opposition to each other in
beating up the egg, and the vibration of the outer coil c¹ also assists the operation.
By thus using two coils c and c joined at their outer circumference in the ring or
coil c¹I obtain a four-fold operation of them, past and against their several parts.
By reciprocating the rod e³ up and down in a right line, I obviate the necessity of the
upper coil e impinging strongly on the rod a and its consequent friction, and also
prevent any twisting or bending of the wire of the rod or coils as would occur if the
rod was connected excentrically to a crank or disc, and 1 prevent any abrasion of the
hands of the user from the presence of the teeth on the wheel W. As the wire
coils c c² are yielding and elastic around the central rod a, they cannot be bent out of
shape or broken as would be the case if they were connected to the rod by any rigid
fastening, the durability of the said coils is thereby increased. The rod a in this
--operation serves as a guide, to prevent the parts of the coils twisting out of their
proper paths with relation to each other, and the said rod is essential to keep both
coils in proper form individually.
It will be observed that this beater will fit into the bottom of-a-round or flat bowl
or dish equally well, as it has the capacity to accomodate the movements of its coils
to cither, without injury, or impairing its operation as the central rod holds and
guides the coils only in the centre of the dish and the coils will conform to a dish of
any shape.
It is not absolutely essential to the operation of the beater part of my device that
both coils and shall be of helical form, although I consider that construction
preferable, as any other form may be employed which will enable them to conjointly
operate substantially as described.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is :-
