do hereby declare the nature of my invention for HOROLOGICAL DIALS to be as
follows:-
Dials for Watches Clocks Regulators Chronometers or other Timekeepers to have
an inner or outer circle of Figures Numerals or Chapters painted engraved printed
etched or otherwise indicated above below or upon in addition to those generally
applied and this extra inner or outer circle to commence with number Thirteen
below above or upon number one (o'clock) on dials as now in use and terminate
with number Twenty Four below above or upon the usual number twelve.

page_text: I, LAWRENCE BARNETT PHILLIPS of Chesham House, Sutherland Avenue,
London, W. in the county of Middlesex, Jeweller, do hereby declare the nature
of my invention for "HOROLOGICAL DIALS," and in what manner the saine is to
be performed, to be particularly described and ascertained in and by the following
statement:
The object of my invention is the construction and arrangement of dials for
watches, clocks, regulators, chronometers or other time-keepers in such a manner
that while the periods of revolution of the hands and the construction of the
internal mechanism of the said time-keepers remains unaltered, they are enabled to
indicate standard or universal time, in which the hours are numbered from 1 to 24-
In carrying out my invention in practice, I provide upon a dial an inner or outer
circle of Figures, Numerals, or Chapters painted, engraved, printed, etched, affixed
or otherwise indicated thereon, such inner or outer circle consists of the numbers
from 13 to 24 and is either exterior or interior to the ordinary circle of figures
numbered from 1 to 12.
In either case the number 13 is placed above or below the number 1 and the
series terminates with the number 24 above or below the number 12.
In place of arranging the said circle of figures from 13 to 24 as above described,
I may if preferred combine them with, or superimpose them upon the ordinary
Figures from 1 to 12, in such a manner that the two component parts of the said
combined or double figures may be clearly distinguished the one from the other.
In order more particularly to explain the features of my said invention, I will
now proceed to further describe it by reference to the accompanying sheet of
drawings, by means of the Figures and letters inscribed thereon.
DESCRIPTION OF THE DRAWINGS.
Fig. 1. represents the dial of any watch, clock, regulator, chronometer or other
time-keeper having an ordinary hour circle A of figures numbered from 1 to 12,
and divided into 60 minutes in the usual way, and a second circle of hour figures B
numbered from 13 to 24 exterior to the said ordinary hour circle, the figure 13
being placed outside or over the figure 1 and the remainder in the same manner;
one set of minute divisions serving for both hour circles.
Fig 2 represents a dial having a similar arrangement of two hour circles, with
the exception that the 13 to 24 circle B, is placed within the ordinary 1 to 12
circle A, the figure 13 being placed inside or below the I and the remainder in the
same manner, and one set of minute divisions serving for both hour circles as
before.
A convenient way in which to apply the arrangement shewn in Figs 1 and 2, to
any existing timekeeper, is to attach, to the dial, a thin flat ring having the numbers
from 13 to 24 indicated thereon.
Fig 3 represents the dial of any watch, clock, regulator, chronometer, or other
timekeeper having an ordinary hour circle A of figures numbered from 1 to 12 and

page_text: divided into 60 minutes in the usual way, but also.having the figures 13 to 24
combined with the figures 1 to 12, so that the figure 13 is combined with the
figure I and so on, the series terminating with the figure 24 combined with the
figure 12-I arrange these double figures so that the component parts can be clearly
distinguished the one from the other.
Two of the said double figures are represented on an enlarged scale in Fig. 5.
Fig 4 represents the dial of any watch, clock, regulator, chronometer, or other
timekeeper having an ordinary hour circle of figures numbered from 1 to 12 and
divided into 60 minutes as usual, and having twelve labels or tablets with the
figures 13 to 24 indicated thereon, applied over or affixed upon the ordinary
figures, the said labels or tablets being of such a size that they preferably only
cover the central portion of the ordinary figures beneath them, thus enabling the
said ordinary figures to be read distinctly.
Two of the said figures with tablets or labels applied thereto are represented on
an enlarged scale in Fig 6.
In place of attaching labels or tablets having the figures 13 to 24 thereon, I may
affix separate figures or letters, such separate figures, being preferably of a different
pattern or design to those upon which they are superimposed.
I can, when desired, apply my invention to a hunting watch or chronometer or
double cased time-keeper, to cause it to indicate universal time, by affixing upon
the cover or engraving or enamelling upon same, a circle of numerals, chapters, or
figures from 13 to 24, the 13 being in such a position upon the cover, that it is
exactly over the I upon the ordinary dial, thereby the time from 1 to 12 is shewn
by the ordinary dial and from 12 to 24 by the circle upon the cover, supposing an
aperture to be made in the cover, as in the ordinary half-hunting watch.
The principal advantages attending the employment of my invention for
enabling time-keepers to indicate standard or universal time may be enumerated as
follows:-
Perfect distinctness of the dials, as the now familiar hour circle consisting of the
ordinary 12 divisions will be retained instead of being cut up into 24 small
divisions, with the figures crowded together as is the case when the hour hand
makes but one revolution in the 24 hours-The minute divisions will also remain
as distinct as before.
The importance to existing time-keepers of not having to provide new motions
or trains of wheels, nor to make alterations in the existing motions or wheels to
cause the hour hand to perform one revolution in 24 hours instead of in 12.
Existing clock dials can have the invention applied to them without the
necessity of removal from position and with only temporary stoppage of the hands.
New dials are not necessarily requisite but if required, the cost is much less
than where alterations have to be made in the train of wheels for the continuous
1 to 24 circle.
New hands for my improved dials are not requisite.
The possibility of using two colors so that the time from midnight to noon shall
be shewn in one color and the time from noon to midnight in another, thus
5 distinguishing them clearly.
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
1. In Dials for watches, clocks, regulators, chronometers or other time-keepers,
0 the combination of an ordinary hour circle of figures from 1 to 12, with an hour
circle of figures from 13 to 24, exterior to the said ordinary hour circle, sub-
stantially as and for the purposes set forth.
2. In Dials for watches, clocks, regulators, chronometers or other time-keepers
the combination of an ordinary hour circle of figures from 1 to 12, with an hour
5 circle of figures from 13 to 24 within the said ordinary hour circle, substantially
as and for the purposes set forth.

page_text: 3. Dials for watches, clocks, regulators, chronometers, or other time keepers
having an ordinary hour circle of figures from 1 to 12, such figures having com-
bined with them the figures from 13 to 24, substantially as and for the purposes set
forth.
4. The combination of 12 tablets or labels having the numbers 13 to 24 thereon,
with the dial of a watch, clock, regulator, chronometer, or other time-keeper,
having an ordinary hour circle from 1 to 12 substantially as and for the purposes
set forth.
5. The combination of separate figures forming the numbers 13 to 24, with the
dial of a watch, clock, regulator, chronometer, or other time time-keeper having
an ordinary hour circle from 1 to 12, substantially as and for the purposes set
forth.
6. In hunting watches or chronometers or double cased time-keepers an extra
hour circle, affixed to or engraved or enamelled upon the outer case, with figures
from 13 to 24, in combination with the ordinary dial, substantially as and for
the purposes set forth.
