Improvements in and relating to Egg Beaters.
I JULIUS SCHREINER of 70 Sebastian Strasse Berlin, in the Empire of
Germany, Engineer, do hereby declare the nature of this invention to be as
follows:
My invention relates to an improved egg-beater, which is very convenient to use
and is more efficient for whipping with. The beater and mechanism for working
the same are directly connected with the cup or basin within which the egg or glair
is being whipped.
A cup or basin, covered or uncovered, is provided of any suitable form and
material, preferably of porcelain, glass or enamelled metal. Through the bottom
of said cup extends a vertical shaft, passing through a stuffing box or an upward
extension formed on or secured to the bottom of the said cup or basin, the lower end
of said shaft turning in a bearing provided in the base-plate of a casing, which
contains the driving mechanism of the said shaft. The upper portion of said' shaft
extends into the cup or basin, and on said shaft a beater is adjustably secured by a
sleeve and screw, or by screw-thread cut on the shaft and a tapped sleeve, or by
other suitable means. The wings of said beater may be of tinned wire or other
suitable material and shape, as usually employed in egg-beaters.
By adjusting the beater up or down on the shaft, the wings will beat more or
less near the bottom of the cup, and, in its lowest position, the beater will be in
contact with the bottom of the cup, the flexible wings bending upwardly to adapt
themselves to the inside surface of the same.
By adjusting the beater, the degree of whipping energy may be varied' as
desired.
Below the bottom of the cup or basin, a casing of porcelain, glass or metal. is
secured by any suitable ineans, by screwing, cementing, or loosely fitted thereto by
frictional contact. Within said casing a roll is secured to the lower portion of the
shaft which extends into the cup or basin, and a cord, band or chain passes from
said roll to the outside through a suitable aperture, the free end of said cord,
band, or chain being preferably connected to a ring, or made to form a loop for
being conveniently seized and drawn out.
Below the roll a spiral spring is arranged within the said casing, one end of
which spring is secured to the shaft which extends into the cup or basin, and the
other end to the casing. It will be easily understood, then, that, by drawing the
cord, band or chain forward and then releasing the saine, the shaft, with beater
secured thereto, will, first, he turned in one direction and then be returned by the
spring in the opposite direction. Thus, by repeatedly drawing the cord out in
rapid succession, the beater will whip the egg or glair with great energy.
If an extension is used to guide the shaft, the egg or glair will, thereby, be
prevented from escaping down along the shaft and a stuffing box may be omitted.
The working operation of said egg-beater is extremely convenient and causes
scarcely any fatigue, while the use of the beating implements generally employed is
very tiresome.

Improvements in and relating to Egg Beaters.
I, JULIUS SCHREINER, of 70 Sebastian Strasse, Berlin, in the Empire of
Germany, Engineer, 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 consists in improvements in and relating to egg-beaters and similar
apparatus, which may equally be applied for whipping cream and other materials
for preparing a variety of dishes, such as cock-tail, cold pudding and the like as
also for making butter. Appliances made in accordance with my invention are
very convenient in use and whipping the glair of eggs or any other material
to be treated can be accomplished in a much more effective manner. The
beater and mechanism for operating the same are directly connected with the
cup or basin, within which the glair or other substance is being whipped.
In the accompanying drawings:-
:―
Figure 1 is vertical section through the centre of the complete apparatus;
Figure 2 is also a vertical section, the foot being shown in side elevation of the
cup or basin and central tube secured thereto;
Figure 3 is a plan view of the apparatus with the whipping tool in position and
Figure 4 is a cross section on the line y of Figure 1.
A, is a cup or basin of any suitable form and material, preferably of
porcelain, glass or enamelled metal. A cover or lid may be used to close the
top, but, in general, the cup may be open during use.
Through an aperture in the bottom of said cup or basin A there is a tube C,
tightly fitted and secured within the said bottom, such tube projects upwards
into the cup.
The foot of the said cup A, may, by any suitable means be
removably secured or held upon a base plate, to prevent its being shifted or being
tumbled when using the apparatus.
g
In Figure 2 a slot 9 is provided in the flange of the foot G of the basin, to engage
with a stud or pin projecting in the base-plate. Or the foot of the cup A may be
sunk into a groove of the base-plate, to hold the apparatus in position while being
used.
The foot G of the said cup or basin A is hollow and in the chamber formed by
the hollow foot, the driving mechanism for the whipping tool is enclosed.
Below the
In a step-bearing D of the base-plate or support D₁ a vertical shaft is supported,
extending through a guide bridge N upwards and through the tube C, from the
top of which tube the said shaft d projects with a square portion d'.
bridge N, two discs ¹¹¹ are secured to the shaft d and between the said discs a
cord, wire, band or chain H, the inner end of which is secured to the shaft or to
one of the discs, is rolled up, the free end of said cord H being carried through a
hole K in the side of the foot G and provided with a cross-pin, ring, handle or
knob l, preventing the free end from slipping into the hollow foot and facilitating
the cord being pulled out. Below the disc a spiral spring M is wound around
the shaft d, the inner end of said spring being secured to the shaft, the outer end
being secured to the bridge N or to any other fixed part of the mechanism. It
will be easily understood, that, by pulling the cord, band, wire or chain H, the said
shaft d will be rotated in one direction whereby tension is given to the spring M,
and that, by releasing the cord, the said spring will return the shaft, rotating the
same in the opposite direction whereby the cord will be wound up again.
The beater or whipping tool F, consisting, preferably, of wire loops bent and
located as shown in Figure 3, are secured to a tube or shell E closed at the top and
having in the said top a square hole fitting upon the square portion of the shaft d.
The tube or shell E fits loosely over the tube C and, as the shaft d is turned, the
tube E with the beaters F readily follow all the movements of the said shaft d.

page_text: As the shell or tube fits loosely upon the square portion d' of the shaft d, it will
be easily seen that the beater may be readily mounted and removed, and the cup or
basin A may be equally lifted from the driving mechanism and from the base-
plate D', when the clasp or retaining pin has been released or disengaged. The
aperture K for the cord H. may be cut down to the lower edge of the foot G,
forming a slot which allows of the cup A being entirely removed from the driving-
mechanism and being taken away.
It will be easily seen, that the contents of the cup A are prevented from escaping
down through the bottom of the cup, as the tube C tightly fits the hole band
extends up beyond the level of the material under treatment; also the shell E
fitting on the square portion of the shaft d prevents any fluid from entering
into the open top of the tube C.
The mechanism, shown in the drawings, for imparting a reciprocating motion
to the shaft and beater F, is, by itself, known and forms no part of this
invention, it may be replaced by any other suitable driving mechanism, from which
a reciprocating, or, if desired, a rotary motion may be derived.
The mode of securing the beater or whipper F to the shaft d may equally be
varied, as desired, for instance, the tube E might be screwed to the top of the
shaft, or adjustably secured thereto by a set-screw or screws.
By arranging the operating or driving mechanism of the apparatus below the
bottom of the cup or basin A the operator will scarcely suffer any fatigue and the
beater may be driven at any desired speed, thus obtaining the desired effect on
the glair or other substance under treatment.
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:
1. An improved beating apparatus consisting of a cup, basin or other suitable
receptacle, a shaft extending through the bottom of said cup, basin or receptacle,
a suitable beater removably secured to said shaft inside the cup or basin, means for
preventing the contents of said cup or basin from escaping through the aperture
in the bottom thereof, and suitable driving mechanism arranged below the cup or
basin for imparting a reciprocating or rotary motion to the shaft and beater,
substantially as hereinbefore described and shown.
2. In a beating apparatus, the combination, with a cup, basin or receptacle, of a
hollow tube or shell tightly fitted into the bottom of said cup, basin or receptacle
and extending into the same, substantially as and for the purpose set forth.
3. In a beating apparatus the combination with a cup, basin or receptacle, of a
vertical shaft extending through the bottom of the said cup or basin, a beater
removably secured to said shaft inside the cup or basin, driving mechanism for
reciprocating or rotating the shaft, and a base-plate or support upon which the
cup or basin is removably held engaged, substantially as set forth.
