I, THOMAS NADEN, the younger, of Birmingham, in the County of Warwick,
Architect, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN RAISING THE COVERS OR LIDS OF HOT WATER JUGS, TEA POTS, COFFEE
POTS, AND OTHER VESSELS," to be as follows:-
My Invention consists of the improvements hereinafter described in
arranging mechanism for raising the covers or lids of hot water jugs, tea pots,.
coffee pots, and other vessels, from the mouths of the said vessels, without the
hand coming into direct contact with the said covers or lids. I joint the
cover or lid to the body of the vessel in the ordinary way, and I make a
knuckle or short arm beyond the said joint, the said knuckle or short arm
forming a prolongation of that portion of the joint connected to the cover or
lid. I make the end of a lever or compound lever, situated in the upper part
of the handle of the vessel, depress the said knuckle or short arm, and thereby
raise the cover or lid.
When I use a single lever to act upon the knuckle or short arm, I construct
it in the following manner:-The lever may either work in a recess in the top
of the handle, with or without the end projecting therefrom, or the end of the
lever may project a short distance below the top of the handle, that is, into
the open space between the handle and body of the vessel. When the
lever is worked from the top of the handle it turns upon a centre at the end

or knob, and made to bear upon the knuckle or short arm, and raise the cover.
Or the middle of the lever has a longitudinal slot made in it, through which a
pin is passed, and upon which pin the lever slides. The end of the slotted
lever projects from the top of the handle, and is pressed towards the cover to
raise the said cover. When the lever projects within the handle, the said
lever turns upon a centre at about its middle. By raising the end of the arm
of the lever, situated within the handle, its opposite arm depresses the knuckle
or short arm on the cover, and raises the said cover; on the pressure being
removed from the lever, in any of the arrangements described, the cover
descends by its own weight and restores the lever to its normal position.
When I employ a compound lever, I prefer to joint the end of one lever to
the knuckle or short arm on the joint of the cover, and joint to the said lever
another lever, the free end of the last-named lever projecting within the
handle of the vessel. By raising the end of this lever by pressure of the
finger, the lever connected with the knuckle or short arm is depressed and
the cover raised. The cover descends by its own weight on the removal of
the pressure from the lever. In place of the knuckle or short arm described,
a pinion may be fixed on the axis of the joint to which the cover is connected,
the said pinion gearing with another pinion turning on an axis in the top of
the handle. The last-named pinion carries a short arm or finger plate. By
raising the said arm or finger plate, the pinion to which it is connected gives
motion to that on the joint of the cover and thereby raises the said cover.
My Invention may be applied to all vessels, the covers of which are or may
be jointed after the manner of an ordinary hot water jug cover.
