COMPLETE SPECIFICATION.
Improvements in or connected with Kettles.
I, JOHN JOSEPH KUCK, of 302 Hornerlandstrasse, Horn, near Hamburg, in
the German Empire, 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:—
This invention relates to a new or improved kettle and its object is to provide
means for automatically opening a valve or tap and allowing the water to make its
exit when the boiling point has been reached. Such a kettle is especially useful
for preparing infusions of tea coffee and the like, the water from the kettle being
caused to flow into the vessel in which the infusion is to be prepared.
The accompanying drawing, which represents a vertical section of the improved
kettle, illustrates in what manner this invention may be carried into effect.
The kettle is heated by a lamp which is lowered and extinguished when the valve
on the exit pipe is automatically opened.
The kettle consists of a suitably shaped vessel K mounted upon a stand B and
furnished with a loosely fitting lid D. The lid D is formed with a projecting rim
or flange W the lower edge of which comes below the water line. As a consequence
the greater part of the steam evolved from the water accumulates within the
upper part of the lid, and upon a certain pressure being attained the lid is lifted
from its seat. The lid is jointed by the hook or hinge E to one side of the vessel
and is provided at its opposite side with a projecting finger or bracket carrying the
vertically sliding bolt X. The lower end of the bolt X when in its lowest
position engages with the longer arm of a bell crank lever R which forms the
handle of the exit valve I.
The shorter arm of the lever R is connected by a cord wire or rod C to a hinged
flap A which supports the lamp L. At the highest position of the lamp L the
counter-weighted extinguishing cap V falls back and is supported by the bracket
or collar P.
Upon the steam from the water in the vessel K attaining the necessary pressure
the lid D is raised from its seat, carrying with it the bolt X and releasing the
bell crank lever R. The weight of the lamp L, which at once commences to
descend, causes the rotation of the lever R thus opening the valve I and allowing
the exit of the water. The cap V is tilted forward by the bracket P during the
descent of the lamp and falls over the wick and extinguishes the flame.
The lid D is provided with a knob or handle F and a small hole G which may
be fitted with a pressure or escape valve. This hole is of sufficient proportions to
permit the escape of steam until the boiling point is reached, when the steam is
generated too rapidly to escape by the hole G and consequently raises the lid.
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. In a kettle or water heating apparatus, the combination of a lid, an outlet
valve, and a moveable lamp, constructed and arranged substantially as and for
the purpose herein before described and as illustrated by the accompanying
drawings.
2. An automatic kettle or water heating apparatus constructed arranged and

page_text: operated substantially as and for the purpose hereinbefore described and as
illustrated by the accompanying drawings.
