mprovements in or connected with Clocks or Watches for Indi-
cating Time for Boiling Eggs, and other Culinary. Purposes.
I, LUDWIG GÜNTHER, of Schwerin, in the Grand Duchy of Mecklenburg-
Schwerin and German Empire, Engineer, do hereby declare the nature of this
nvention and in what manner the same is to be performed, to be particularly
escribed and ascertained in and by the following statement :-
The object of the present invention, as represented in the annexed drawing, is
o shew the necessary time required for the boiling of eggs used as human food,
uch as hen eggs, duck eggs, turkey eggs, and plover eggs. It can also be used
for marking the time required for cooking, baking, and other culinary time
measurements.
The object of the present invention, as represented in the annexed drawing, is
o shew the necessary time required for the boiling of eggs used as human food,
uch as hen eggs, duck eggs, turkey eggs, and plover eggs. It can also be used
for marking the time required for cooking, baking, and other culinary time
measurements.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a front view of the apparatus.
Figure 2 is a side view; and
Figure 3 shews the apparatus with the cover and dial removed. These three
figures are full size.
Figure 4 shews the dial double full size.
In the case A there is an ordinary clockwork, which like other watches, can be
wound up at a. By means of the clockwork, the hand b is moved round the dial
once in ten minutes. In the casing there is also a small lever d, movable on the
pin c, which bears at one end the stop pin e, and at the other end the pressing
pin (see Figure 3). The stop pin e extends through the dial at the number 10;
the pin extends laterally out of the case. The lever d is constantly kept in the
position shewn in the drawings by means of the spring g. The object of the lever
arrangement is to stop the hand b so that when it comes against the stop pin e, it
is held at the number 10. If the pin is pressed, the hand becomes free again,
gives one turn and again stops against the stop pin e.
The dial B is divided into different circular divisions, which, for easier reference,
can be painted in different colours. The outer circle, in which the incision e¹
(Figure 4) for the stop pin is shewn, is divided into 10 equal parts, and the
different points marked with the numbers 1, 2, 3,-10. The minutes are further
divided into halves. The second circle shews the limits within which the hand has
to run, to boil domestic hen's eggs; namely, to the first arrow point, if they are to be
boiled soft, and to the second if hard. The third circle shews the limits to which the
hand has to reach, in order to boil ducks eggs, namely to the first arrow point if
soft, and to the second if hard. In the same manner the fourth and fifth circles
are arranged for turkey's and plover's eggs.
It is obvious that the apparatus can be made in the form of a watch, or of a
wall clock, the principle is the same and therefore only described here in one form.
The use of the egg clock according to this invention has great advantages.
When the eggs are placed in boiling water, the watch is taken in the hand, and
by pressing the pin f, the hand is allowed to run to the corresponding division or
mark, upon reaching which the eggs are taken out. The hand will always, after
use, move back to 10; and the watch is again ready for further use.
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 1
claim is :-
1. A clock or watch, consisting of a clockwork having a hand adapted to move

page_text: on a disc or dial on which there are marked 5 concentrical rings, the first of which
is divided into 10 or 20 parts, the second into 2 divisions; the fourth into 2 parts,
the fifth being without divisions, the hand being so arranged as to be set going
and stopped by means of a lever d, the whole having for its object the correct
boiling of hen eggs, duck eggs, turkey eggs, and plover eggs, or other culinary
operations by distinctive marks shewing the time required for each operation.
