An Improved Whisk or Beater for Culinary and other Use.
I, PAUL JOHANNES MÜLLER of 59 Adalbertstrasse, Berlin, Architect 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:—
The object of this invention is an improved whisk, beater or mixer which is
principally intended for beating eggs whipping cream and other similar culinary
use but which can be used as a hand mixer for other purposes, the purpose of
the improvements being that the whisk can be used and operated by one hand
only without requiring to be held in position by the other hand as is the case
with other articles of the like nature at present in use. The other hand of the
user is thus left free for adding materials during the action of the whisk or for
other employment.
The improved whisk is also capable of operating upon very small quantities of
materials, or upon such quantity as lies at the bottom of the receptacle into which
the whisk is placed.
Fig. 3 is a detail of the upper bearing of the spindle.
Fig. 4 a similar view of the lower bearing.
Fig. 5 is a plan view of Fig. 1.
In the axial centre of the frame a is mounted the spindle c, having a socket f
supported on a pin bearing e at the lower end, and a pin e¹ lying in a socket
bearing flat the upper end. The frame a carries the cross plate h which is of
considerable weight in proportion to the other parts of the implement, and to the
sides or edges of this plate are attached bars a parallel to the bars at the sides of
the frame a, and attached to the latter by the hoop a². The side bars of frame a
and the bars a' carry inwardly directed plates or arms b which may be perforated;
and the spindle c carries similar outwardly projecting arms which, when the spindle
is revolved, move in paths between the arms b. The arms d may also be per-
forated, and in order to lessen their resistance to backward movement they are
curved in the direction of their forward movement, so that when the driving nut g
of the Archimedian screw on the spindle c is raised the resistance offered by the
material whisked to the rearward passage of the arms d may be reduced.
It will be sufficient to place the whisk in the receptacle containing the material
to be whisked and it need not be held down in said receptacle while the nut 9 is
moved up and down, since owing to the practically frictionless bearings of the
spindle, to the weight of plate hand to the curvature of the arms d as before-
mentioned, the gravity and inertia of the frame and other parts will be sufficient to
overcome the resistance to the upward movement of nut g.
It will be obvious from Fig. 2 that the arms a' are of such a length that a slight
lateral tilting of the whisk will permit the lowermost arms d to nearly touch the
bottom of the receptacle in which the whisk is placed.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
:―
1. A whisk or similar instrument having a weighted frame adapted to hold it in
place against the force of resistance to the upward movement of the nut moving

page_text: 2. A whisk or similar instrument in which the whisk arms offer decreased
resistance to backward turning, whereby the weight of the frame and other parts
is rendered superior to the upward force exerted on the nut by which the whisk
arms are revolved.
3. A whisk or similar instrument having frame a with weighty plate and
bars a', arms b in said frame and bars, and spindle c with arms d and Archimedian
screw and nut; the bars a¹ being of such length that the whisk may be tilted for
the purpose described.
4. A whisk or similar instrument having a weighted frame a with arms b, and a
rotary spindle mounted therein by pin and socket bearings or otherwise, with
Archimedean screw and nut g, the said spindle having arms d curved in the manner
and for the purpose specified.
