Improvements in a Mechanical Time Lifting Apparatus for Removing
Eggs from Boiling Water.
I, OTTO FROMMANN, of 1, Kaiser Platz, Frankfort-on-the-Main, in the Empire
of Germany, Inventor, do hereby declare the nature of this invention to be as
follows:-
The subject of the present invention is an apparatus for cooking eggs, in which a
clock work movement lifts the eggs at a given or predetermined moment out of the
boiling water.
The apparatus comprises a box with six parallel faces two by two and a bottom
in the shape of a parallelogram parallelipedical shaped box) enclosing a toothed
wheel, to which is connected a spiral spring, and which toothed wheel is mounted
upon an axle capable of revolving in the walls or sides of the said box.
The toothed wheel has at its periphery a gap formed by filing out some consecu-
tive teeth of the said wheel, which latter gears or meshes with a pinion through the
medium of which the speed of the rotary movement of the wheel is regulated by a
flier with wings in such a manner that a hand or pointer fixed near the extremity
of the axle carrying the toothed wheel, and projecting outside the box, indicates
the minutes upon a suitable dial plate secured upon the exterior surface of the
former. The above mentioned axle is so arranged as to be capable of being displaced
longitudinally in such a manner as to throw the toothed wheel out of gear with
the herein before mentioned pinion, an antagonistic spring fixed to the bottom of
the box, tending to bring back the axle into the position wherein the pinion gears
or meshes with the toothed wheel.
To this latter is fixed a radial arm carrying a pin which projects laterally. In
the path of this pin is situated a bracket the lower extremity of which is guided in
a socket curved in the arc of a circle and containing a spring roller which tends
to move in an upward projection the said bracket. To this latter is attached one of
the ends of a small chain the other end of which is secured to one of the ends of a
lever oscillating upon a support fixed to the rear wall of the box and to the other
end of which lever is suspended a basket containing the ends to be boiled or cooked
and which is submerged in boiling water contained in any suitable receptacle
placed upon the fire, and to which receptacle the apparatus is fixed by means of a
screw clamping device.
To employ the apparatus, the toothed wheel is thrown out of gear by pressing on
a button or knob fixed to the end of the spindle the hereinbefore mentioned hand
or pointer being then set opposite the figure upon the dial plate which indicates the
number of minutes during which it is desired to boil or cook the eggs; the button
or knob is then released which allows the toothed wheel to again drop in gear and
causes the descent of the arm of the lever carrying the egg basket. The toothed wheel
takes as many minutes as is marked by the hand or pointer upon the dial plate to
arrive at such a position as to present its cut away or non toothed portion to the
pinion, and at the moment that it does so the toothed wheel being no longer under

page_text: the action of the regulator with rings, the spring is free to develop its whole
energy, the toothed wheel turns rapidly, through a certain angle and the pin
comes in contact with the bracket, which has for result to cause the lever to
oscillate in such a manner that the basket containing the eggs is suddenly raised
out of the boiling water.

Improvements in a Mechanical Time Lifting Apparatus for Removing
Eggs from Boiling Water.
I, OTTO FROMMANN, of 1, Kaiserplatz, Frankfort on the Main, in the Empire
of Germany, Inventor, 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 subject of the present invention is an apparatus for boiling eggs, wherein a
clock work movement can be set to withdraw the said eggs on the expiration of
any desired predetermined time, from the boiling water.
And in order that my invention may be thoroughly understood, I now proceed
to describe the accompanying drawing thereof, reference being had to letters
and figures marked thereon.
Fig. 1, is a longitudinal section.
Fig. 2, is a transverse section.
Fig. 3, is a perspective view. of the apparatus..
In the box or casing A is arranged a spring provided on its rear face with a
toothed wheel which gears or meshes with the pinion C, and the speed of rotation
of which is governed by a flier with wings or vanes 1) in such a manner that the
clockwork movement can be moved up and set by means of the hand or pointer Mand
of the dial L, which is divided into minutes, and mounted upon the front face, of the
apparatus. The toothed wheel B is provided on its circumference with a gap or.
interruption b which has been formed by removing several teeth by means of a file.
It will be seen then that as soon as this gap or interruption comes opposite
the pinion C the gearing or meshing of the toothed wheels will be suddenly
interrupted, and the wheel B, relieved of the regulating or governing action of the
winged or vaned flier, will rapidly continue its motion under the action of the
spring which then gives off freely its full power. Moreover, the toothed wheel B
is fitted with an arm E carrying laterally a pine which rests or strikes when the
wheel escapes or. runs free, against a slide piece f mounted in a curved socket t,
secured to the front wall of the box or casing and enclosing a spring w which
resists the movement of the said slide piece. The said slide piece transmits the move-
ment which is imparted to it by the pin e, to the stem or rod G through the medium
of a small chain m attached to the said stem or rod and to said slide piece. The
stem or rod G pivots round the axis h in the extension H forming one piece with
the rear plate of the box or casing A. The fork K serves. to fix the apparatus
to the saucepan unless it may be desired to entirely suppress this fork and 'to
place the apparatus on the stove or other place.
When it is desired to use the apparatus the wheel C is first thrown out of gear
by pressing on the button P, and the hand or pointer is next placed opposite the
figure on the dial L which indicates the number of minutes during which it is

page_text: desired to boil the eggs. Upon then releasing the button P the wheel C will be
brought back to its normal position by a spring 0 arranged in the bottom of
the box A. The setting of the hand or pointer upon the dial L effects a lowering
of the stem G and the receiver or holder for the eggs. Indeed, said hand being
moved to the right (Fig. 3), the pin e is disengaged from the slide piece f, which
is now brought to the upper end of the curved socket t by the action of the spring w,
whereby the free end of the stem G carrying said receiver or holder will be
lowered.
The wheel B takes as many minutes as are marked by the hand, pointer, or
index M upon the dial L, to return to the position in which the wheels B and C
are placed out of gear. At that instant the pin e strikes forcibly against the slide
piece fand in this manner forces the short arm of the lever G to descend rapidly
and in consequence to raise or lift the eggs out of the boiling water at the desired
time.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
An apparatus for boiling eggs characterized by a spring actuated wheel receiving,
through the medium of a governing or regulating arrangement of any suitable
description, a rotary movement corresponding exactly to an indicator of minutes
M, L, the said wheel being provided with a gap, interrupted, or cut away portion, b
in the toothed part thereof so that it will be suddenly thrown out of gear with the
governing or regulating device or apparatus C, D, and will strike suddenly through
the instrumentality of a pin e carried by the arm E upon the spring actuated
slide piece fmovably mounted in a socket, this slide piece forcing, through the
medium of a chain, the lever G to swing upon the pivot h and to instantly or
quickly raise out of the boiling water the receiver or container for the eggs, which
is suspended at the other end of the lever G, substantially as hereinabove described
and illustrated in the annexed drawing.
