I, GEORGE CECIL DYMOND, M.1.M.E., of W. P. Thompson & Co., of The Agency
for Foreign Patent Solicitors, 6, Lord Street, Liverpool, & 6, Bank Street,
Manchester, both in the County of Laucaster; 118, New Street, Birmingham, in

Patent Agent, 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 clocks going for a long period (so-called year clocks) hitherto known are of
more or less complicated construction whereby not only is their cost of manufacture
considerably increased but frequent stoppages and irregularities are caused.
The present invention is based on the endeavour to produce with the simplest
possible means a clockwork capable of going for an extremely long period much
exceeding the ordinary one and amounting to not less than one year.
This object
is sought to be attained by employing on the one hand as source of power a very
powerful spring with correspondingly formed barrel, and on the other hand a very
small train of wheels and escapement only requiring a small amount of power, such
as are employed for watches As however these two, to a certain extent opposite
constituents, cannot be directly combined the arrangement is adopted of causing the
power of the spring to act first on a wheel train of suitable strength capable of
receiving and transferring this power. This train of wheels is then suitably con-
nected with a small train of wheels so that the strong spring acts indirectly and
without harm on the fine watch mechanism and can produce the effect hereinbefore
mentioned.
In the accompanying drawings, Figures 1, 2 and 3 are sectional elevations, and
Figure 4 a side view of clock work mechanism arranged in this manner, whilst
Figure 5 is a detail view.
In carrying the invention into effect a barrel b projecting through a recess in the
full frame plate B and mounted with its arbor a in another full plate A, and in a
half plate Ċ transmits, by means of teeth b¹ on its periphery, the rotary movement
imparted to it by a strong spring c to a strong pair of wheels d e arranged between
the full plates A and B. A fine watch movement W is screwed to the one plate B,
the driving arbor f¹ of which movement is prolonged from the second or large
second wheelf to one side through the two plates A and B and is mounted in the
same, and carries on its free end a small wheel g connected with the hands
mechanism Z of the dial plate. A pinion h is arranged between the two plates A
and B on the arbor of the said large centre wheel, with the teeth of which pinion
the transfer wheel e of the strong train of wheels e b¹ d engages and thereby effects
an intermediate transmission of power to the weaker or finer movement W.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to
ne by my foreign correspondent, I declare that what claim is
--
A clockwork with a long going period characterised by a strong spring (c) acting
on a strong train of wheels (e b¹ d) being connected by means of an intermediate

page_text: gearing (h f) with a small train of wheels of a watch mechanism (W) so that the
power of the strong spring acts only indirectly and without harm on the fine watch
mechanism, substantially as herein before described.
