Improvements in Cases for Clocks.
I EDWARD LIGHT of 15 Lime Street in the City of London, Sheffield and
Birmingham Warehouseman, do hereby declare the nature of said Invention for
IMPROVEMENTS IN CASES FOR CLOCKS" to be as follows:-
My invention relates more particularly to Cases for Clocks of an ornamental
character and consists in the production of such cases in imitation of marble and
other similar substances in the following manner.,
I make the body of the case of any design I please in China Clay or other
suitable pottery earth and bake into Biscuit ware after which I treat the surface
with colouring matters suitable for burning in, and paint thereon such design or
color the respective parts in reference to the material to be represented as I may
desire.

.
By using a common Clay for this purpose I am able to produce cases at a very
moderate price scarcely to be distinguished from those made of marble and of a far
more expensive character.
The nature of the material, it being a very bad conductor of heat, and the
circumstance that I am able to enclose the clock on all sides, except the back and
face, with a complete shell of the earthenware, keeps the clock movements at a
very equable temperature and enables it to keep more correct time than when
mounted in any of the ordinary materials.

page_text: I EDWARD LIGHT of 15° Lime Street, in the City of London, Sheffield and
Birmingham Warehouseman, do hereby declare the nature of my said invention
for "IMPROVEMENTS IN CASES FOR CLOCKS " and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement :-
My invention, relates more particularly to Cases for Clocks of an ornamental
character and consists in the production of such cases in imitation of marble and
other similar substances in the following manner:
I make the Case of any of the Clays ordinarily used for the manufacture of the
cheaper kinds of, preferably white, earthenware for which purpose I prepare a
mould (according to any design I wish to produce) in several pieces properly fitting
together Into this Mould "bat" is introduced as is done in the manufacture of
hollow ware and if required a base or top or front or back or any of them are
subsequently placed upon the body thus made, such portions being if necessary
fashioned in separate moulds and then united while still plastic.
The case thus made in the rough is next dried and baked into biscuit ware after
which I paint it with such colors as are usually employed in ceramics the painting
being so executed as to imitate Marble Malachite Granite or other kinds of stone
which are costly either by reason of the value of the raw material or of the
difficulty of working them, or any other design or pattern may be produced thereon
by hand painting or transfer or a combination of the two. I prefer what is known
as underglaze work for the ground colors and finish up the details of the design with
overglaze work, but the whole of the coloring may be done over glaze being fixed
at the appropriate stages, gilding bronze, and other metallic colors may be used to
imitate ormolu or the like-By using a slightly colored clay, such for instance as
cream colored, which may be left uncolored in places a pleasing effect is produced.
I have thus far described the process for making cases with plain or nearly plain
surfaces; when desired the ornamentation may however comprise relief work or
modeled work executed in clay before burning and then colored in the manner
already set forth I may also employ ornamentation produced by impression or
incision.
By using a common clay for this process I am able to produce cases at a very
moderate price scarcely to be distinguished from those made of more expensive
materials and of a far more costly character.
The nature of the material it being a very bad conductor of heat and the
circumstance that I am able to enclose the clock on all sides except the face, or
back and face, with a complete sheet of the earthenware, keeps the clock move-
ments at a very equable temperature and enables it to keep more correct time than
when mounted in some other ordinary materials.

page_text: 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:
The production of clock cases made of common earthenware so ornamented and
treated as to resemble Marble, Malachite, or other costly stone, metals, or the like
substantially in the manner and for the purpose hereinbefore described and set
forth.
