COMPLETE SPECIFICATION.
Appliance for Securing the Covers of Culinary Vessels in the Closed
Position.
I, Oliver Imray, of Birkbeck Bank Chambers, Southampton Buildings, in
the County of London, Chartered Patent Agent, do hereby declare the nature of
this invention (as communicated to me from abroad by the Firm of Joh.
Baumann's Wive, of Amberg, Bavaria), 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 an appliance for securing the covers of culinary vessels
whether for boiling steaming or roasting, in the closed position which appliance is
of a very simple construction and so arranged that it can be readily applied to any
kind of culinary vessel that has a projecting rim at top.
The appliance is shewn on the accompanying drawings in which Fig. 1 shews
an elevation of the same as applied to a culinary vessel, Fig. 2 shews a plan, and
Fig. 3 a cross section. To the cover D) of the saucepan G is riveted an angle
piece a to which is pivoted a lever b having a laterally projecting finger e, and a
suitably formed handle d. For vessels of large diameter the cover can be
strengthened by fixing under the angle piece a a strengthening piece e.
cover D having been fitted on the vessel G, a bar f with hook-shaped ends h is
slid laterally over the projecting rim of the vessel, so that the bar f is situated
over the finger of the lever 6 when this is in the lowered position, the ends
being engaged with the underside of the rim i.
The
The lever is then turned upward so that the finger c enters the cranked middle
part of the bar f, and in pressing against the underside thereof forces the
lid D downward on to its seat. The cranking at of the bar f has for its object
to enable the pressure upon the lid to be regulated; namely if lever b be brought
into the upright position, a strong downward pressure will be exerted on the lid,
while if it bears in a more or less inclined position upon the sloping surface of the
part y, as indicated at Fig. 1, the pressure upon the cover will be less. It is
therefore possible by means of the said closing appliance to effect a greater or less
steam pressure within the vessel G, according as the lever bis placed more or
less vertical or inclined. When the lever b is turned entirely down, the cover
will be entirely relieved of pressure.
When the food in the vessel is being cooked under strong pressure, the lever b
being vertical it is advisable, before entirely freeing the cover so as to open it,
to bring the lever first in the inclined position, as at Fig. 1, so that the steam
pressure can to a certain extent escape before the lever is turned quite down for
opening the cover.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what
I claim is:
i
An appliance for securing the covers of culinary vessels in the closed position,
consisting of a bar f with middle cranked portion and

page_text: adapted to engage under a projecting rim of the vessel, in combination with a
cover to the upper side of which is pivoted a lever b with finger e and handle d,
so that on turning the lever into the vertical position the finger c presses against
the cranked portion of the bar f so as to forcibly hold the cover down on the
vessel, while when the lever is brought into an inclined position the finger c, in
bearing against the inclined side of the cranked part of the bar, will exercise a
less pressure on the cover, substantially as described,
