Improvements in Clocks.
I, PHILIP ARTHUR NEWTON of the Office for Patents, 6 Bream's Buildings,
Chancery Lane, in the County of London, 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 :-
This invention relates to clocks with main wheel and winding arbor concentric
with the centre of the clock, and with the centre spindle passing through the
winding arbor. The object of the invention is to obtain separate bearings for the
said arbor and spindle, in which each works independently of the other, in such a
manner that the friction is reduced.
In the accompanying drawing,
Figures 1, 2, and 3 represent sectional views of a clock movement embodying
the present invention, Fig. 1 representing a vertical section in the linex of
Fig. 3; Fig. 2 a vertical section in the line y y of Fig. 3; and Fig. 3 a central
horizontal section.
Similar letters of reference designate corresponding parts in all the figures.
In carrying out the invention, three plates A', A. A³ are used, which are con-
nected together by pillars a a', such as are commonly employed for the protection
of the plates of clock movements. The ordinary time train T, T, is placed
between the first and second plates A', A2, and the main spring B and the main
wheel C between the second and third plates A', A³, and the intermediate pinion p
is arranged to project through an opening in the second plate A', sufficiently for
the main wheel to gear with it. The spindle of the intermediate pinion p has its
front journal in a bearing in the plate A', and its rear journal in a projection c,
which is made in the same piece with the plate A', by striking up a portion of the
said plate.
The second or middle plate A has a central boss or hub d on its back, to form
an inside bearing for the front end of the hollow main wheel arbor, e.
The rear end of the said arbor e is pivotted to work in an an outside bearing in
the third or rear plate A³, and projects far enough through the back of said plate,
to receive the key k.
The front end of the central cavity of said arbor is enlarged to receive the hub
or inside bearing d provided for its support on the back of the middle plate A*.
The centre spindle has one of its bearings in the centre of the front plate A',
and the other in the centre of the middle plate A².
By this mode of supporting the central main arbor and centre spindle, separate
and distinct bearings for each are provided, for although each has a central bearing
in the middle plate, the bearings for the two are separate, and neither the arbor
nor the spindle is subject to friction by the operation of the other.
In Figures 2 and 3 there is represented in front of the main spring B, and
between the said spring and the main wheel C and its ratchet wheel G, a guard
plate, which is held against shoulders on the pillars a a¹, but this plate has
nothing whatever to do with supporting the movement. It is simply a guard to
prevent the mainspring over-riding the main wheel and ratchet wheel.
The outer end of the mainspring B is secured to one of the pillars a, and the
inner end to the central spindle d, in the usual manner, and all the parts not
particularly described are or may be the same as in well known clocks.

page_text: 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 me
from abroad, I declare that what is claimed is-
1
The combination in a clock movement with a centrally arranged main wheel and
hollow winding arbor, and a centre spindle passing through said arbor, of three
united supporting plates, the front one of said plates containing a bearing for the
centre spindle, the rear one of said plates containing a bearing for the rear part of
the winding arbor, and the middle one of said plates containing a fixed central
bearing for the said spindle, and having on its back a central hub or boss, the
exterior of which forms a fixed bearing for the front end of the winding arbor,
substantially as herein set forth.
