PROVISIONAL SPECIFICATION.
Improvements in the Illumination of Church, Turret, and other
Clock Dials.
We, REUBEN RIPPON, and EDWIN FREDERICK RIPPON, both of The Wicker,
Sheffield, in the County of York, Turret Clock Manufacturers, do hereby declare
the nature of our invention to be as follows:-
This invention relates to the illumination of the dials of church, turret, and
other clock dials, the object being to accomplish such illumination in a more
efficient and economical manner than at present.
We propose to use a lamp of horizontal cylindrical form, the body and the back
being preferably of sheet iron fitted with an enamelled iron reflecting cone in the
front, and at the back of the interior with a reflector of opal glass or other similar
material.
Near the centre of the lamp we fix two or more burners for the lights, the number
being regulated by the size of the dial to be illuminated, and above the said burners
opening into the body of the lamp we fix a chimney to carry away the heat and
products of combustion into the open air, or otherwise away from the clock and
dial.
We fix the lamp so constructed round the central hour tube which thus passes
centrally through the lamp supporting it by brackets or other suitable means as
will allow the light to be effectively thrown and equally diffused over the whole of
the dial.

COMPLETE SPECIFICATION.
Improvements in the Illumination of Church, Turret, and other
Clock Dials.
We REUBEN RIPPON and EDWIN FREDERICK RIPPON both of The Wicker,
Sheffield in the County of York, Turret Clock Manufacturers 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 the illumination of the dials of church, turret, and other
clock dials, the object being to accomplish or effect such illumination in a more
efficient and economical manner than heretofore.
The annexed sheet of drawings shows how we carry out our invention in the
construction of the lamp, and its arrangement in relation to the dial to be
illuminated.
Fig. 1, is a front elevation of the lamp showing the lights.
Fig. 2, side elevation of same.
Fig. 3, back elevation of same.
We construct the combined lamp and reflector as follows: we make the body A,
cylindrical by preference, having a circular conical reflector B, in front, with its
inner edge B, carried into the body A, as shown, so as to catch and prevent the
smoke and effluvia passing out of the lamp except by the proper exit, which is a
chimney C, fixed upon the body of the lamp directly above the lights.
We make the lamp in two parts the division D, being made horizontally through

page_text: the centre, for convenience in fixing in the desired position, the two parts are
afterwards bolted together.
The inside of the cone, and the interior of the body we prefer to paint with white
enamel paint to reflect the light forward upon the dial which is situated in front of
the lamp.
The lamp is fixed round the hour tube" E which forms the centre point of the
lamp, and on each side of the "hour tube," there is a plate F, F; painted white to
conceal the tube and prevent it throwing a shadow.
In the body of the lamp we arrange two or more lights according to the size of
the lamp and the dial to be illuminated, and placed at such an angle with the
conical reflector that the light will be thrown equally over the dial.
Over the lights we fix the chimney C, before mentioned, which may be taken to
any desired height so as to carry off the heat and smoke.
The lamp is fixed behind the dial at any suitable distance from the glass but
always in a central position as it surrounds the spindles which carry the hour and
minute hands, and it may be supported by suitable brackets or like devices.
A door G, may be fixed in a convenient position either on the side or back of
the body to enable the interior to be inspected.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same may be performed, we declare that what
we claim is :-
1. In the illumination of clock dials, a lamp constructed as herein before described
and fixed round the hour hand tube, at the back of the dial for the purpose
specified.
2. A lamp having a conical reflector B, a body A, chimney C, two plates F, F,
and divided into two parts that can be readily fixed together so as to surround the
hour hand tube of clocks for the purpose of illuminating the dial, constructed and
arranged as hereinbefore described and as illustrated.
