PROVISIONAL SPECIFICATION.
Improvements in and connected with Time Pieces and Clocks for
Indicating the Time at Night.
I, WILLIAM HENRY ALDERSON of 88 Wilmslow Road, Withington, near
Manchester, Merchant, do hereby declare the nature of my said invention to be
as follows:-
My invention consists of a luminous faced clock or time piece capable of being
attached to the arm of a gas bracket chandelier or pendant for indicating the time
at night.
This improved time piece is provided with the usual clock mechanism which is
enclosed within a casing and the dial or face of the time piece is made of opaque
glass or other similar and suitable material capable of transmitting light and is
arranged above and apart from the clock mechanism in the casing aforesaid. The
dial or face is provided with the usual hands for indicating the time such hands
being actuated or driven by a small pinion and crown wheel from the clock
mechanism below.
The back of the casing is furnished with a metal loop or its equivalent for
readily attaching the clock to the gas bracket. By now attaching my improved
clock or time piece to the gas bracket and arranging it in front of the gas flame
the face or dial of the clock will be lit up and thus the hour or time will be
indicated.
In the day-time the clock may be .detached from the gas bracket and may be
used as an ordinary clock.

'Improvements in and connected with Time Pieces and Clocks .for
Indicating the Time at Night.
I, WILLIAM HENRY ALDERSON of 88 Wilmslow 'Road, Withington, 'near
Manchester, Merchant, do hereby declare the nature of my said invention and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
My invention consists of a luminous faced clock or time piece capable of being
attached to the arm of a gas bracket chandelier or pendant for indicating the time
at night.
In accordance with my invention the clock mechanism or works portion of my
improved time piece is enclosed within a casing and the dial or face is made of
glass, alabaster or other suitable material and is arranged above and apart from
the clock mechanism in the casing aforesaid. The dial or face is provided with
the usual hands for indicating the time, such hands being actuated or driven by
a small pinion and crown wheel or equivalent mechanism from the clock mechanism
below.
The back of the casing is furnished with a metal loop or its equivalent which is
passed over the burner in attaching the clock to the gas bracket.
By now arranging it in front of the gas flame the face or dial of the clock will
be lit up and thus the hour or time will be indicated or made visible.
In the day time the clock may be detached from the gas bracket and may be
used as an ordinary clock.

page_text: And in order that this my said invention may be more readily understood and
carried into practical effect I have hereunto annexed a sheet of drawings and will
now proceed to describe the same with the assistance of the various figures and
letters of reference marked thereon.
Fig. 1. is a rear view and Fig. 2. a side view of my improved clock or time
piece.
A is the dial or face of my improved clock made of glass alabaster or other
suitable material capable of transmitting light and B is the box or casing below
containing the works mechanism.
In lieu of the arrangement of crown wheel and pinion aforesaid and described in
my Provisional Specification for actuating the hands C and C¹ I prefer to employ a
set of arbors D and D₁ bevil wheels E and E' and spur wheels and pinions F
and F. The latter being supported by a bracket G and the former by the
bracket H. This arrangement I have found to cast the least shadow.
The dial is by preference surrounded by the frame J forming part of the front
of the clock to facilitate the fixing of same in position and it may be enclosed by a
glass face to prevent damage being done to the fingers and preserve the face of
the dial.
I is the metal loop which screws into the back of the clock and is slipped over
the burner in attaching the clock to the gas bracket K. To adjust the clock to
suit the gas bracket the loop I is screwed in or out of the back of the clock and to
keep the clock upright a plate is fixed at L which bears against the square end of
the bracket.
It will readily be apparent that a mere glimmer of light will suffice to illuminate
the dial and thus make the time visible at night. The improved clock may be
used in conjunction with a night-light, candle or oil lamp; a special ledge may be
made behind the casing B for the night-light, candle or oil-lamp to rest upon or the
loop I may be made to support the same.
The clock is wound up through the bottom of the casing and regulated through
an opening in the side.
Having thus particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim as my invention and desire to secure by Letters Patent is :-
:-
1st. A clock or time piece having a glass, alabaster or other similar dial or
face arranged above the works mechanism, which clock is capable of being attached
to the arm of a gas bracket, chandelier or pendant by means of the loop or its
equivalent substantially as herein before described and illustrated on the accom-
panying drawing.
Dated this 1st day of June 1892.
