PROVISIONAL SPECIFICATION.
Improvements Applicable to Kitchen Boiler Lids.
We FREDERICK SMITH and SAMUEL HENRY SMITH of the firm of John Smith and
Sons of Openshaw Bridge Iron Works Openshaw in the County of Lancaster [ron-
founders do hereby declare the nature of this invention to be as follows:-
The object of these improvements is to afford a ready and economical means of
hinging the lid of a kitchen boiler to the top plate of the same.
For this purpose we cast at each end of one side of the lid a hinge pin or pivot,
and at a corresponding part of the opening in the top plate of the boiler we cast
underneath the same on one side a lug having a corresponding hole, and at the
other side we cast a recess upon at the top, so that one hinge pin or pivot of the lid
can be passed end ways into the hole, and the other laid into the recess.
The top of the recess above this hinge pin is then closed by a small plato prefer-
ably let in "flush" and screwed on, so as to prevent the pin from rising out of the
recess, and thus a simple and convenient hinge is made for the lid.

¡OMPLETE SPECIFICATION.
Improvements Applicable to Kitchen Boiler Lids.
We FREDERICK SMITH and SAMUEL HENRY SMITH of the firm of John Smith and
Sons of Openshaw Bridge Iron Works Openshaw in the County of Lancaster Iron-
founders, 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 object of these improvements is to afford a ready and economical means of
binging the lid of a kitchen boiler to the top-plate of the same.
The nature of our invention and the manner in which the saine is to be performed
or carried into practical effect will be readily understood on reference to the sheet of
drawings hereunto annexed and the following explanation thereof.
Fig. 1 is a plan view of the top plate of the boiler, Fig. 2 is a section thereof
taken through about the line A, B in Fig. 1. Fig. 3 is a plan view and Fig. 4 an
edge view of the boiler lid. Fig. 5 is a plan view of the top plate with the boiler
lid in place and Fig. 6 is a section of the same through about the line C-D in
Fig. 5.
Similar letters are placed upon corresponding parts in all the figures.
For the purpose of our invention we cast at each end of one side of the lid a a
hinge pin or pivot b (see Figs. 3 and 4) and at a corresponding part of the opening
of the top plate c of the boiler (Figs. 1 and 2) we cast underneath, the same on one
side or lug having a corresponding hole e, and at the other side we cast a recess f
open at the top so that one hinge pin or pivot b of the lid a can be passed end ways
into the hole e and the other hinge pin b laid into the recess f..
ແ
The top of the recess f is then closed by a small plate g (Fig. 5) preferably let in
flush and fixed by a screw h so as to prevent the pin b from rising out of the recess,
and thus a simple and convenient hinge is made for the lid a.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what we
claim is :-
The combination with two hinge pins cast on the lid, of a lug and hole cast on
one side and a recess at the other side of the opening in the top plate, the recess
being covered by a small plate screwed or rivetted on, to keep the hinge pin in its
place, substantially as and for the purpose herein before described.
Dated this 20th day of December 1889.
