Improvements in Watches.
1, RICHARD THORNELOE of Eaton Lodge Eaton Road, Coventry and Stanton
House, 13, Stanton Street, Coventry, in the County of Warwick, Watch and
Chronometer Manufactuer, also at 15, Northampton Square, London, as James
Hoddell & Co. and John Forest Chionometer Makers and Watch 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:-
My invention relates to improvements in watches and consists, in the first part, in
an improved construction of ratchet wheel for either a going bariel watch or a fuzee
watch, and which said intchet wheel is particularly adapted to the barel arbor ;
in the second part to an improved construction of intermediate wheel and its ai bor;
in tbe thnd part to the construction and arrangement of an up and down to a going
banel watch, in the fourth part to the setting of the hands to a full plato watch
and, in the fifth part, to a winding arrangement whereby the winder axis of a going
barrel watch is planted identical with the winder axis of a fuzee watch.
Fig. 1 of the accompanying sheets of drawings represents on an enlarged scale a
going bariel watch constructed and fitted with improvements according to the first,
second, and thud parts of my invention The view illustrates the dial removed
disclosing the movement in its case from the pillar plate side, which said view
illustrates my improved atchet wheel, also an up and down o tell-tale, which
intimates to the owner when the watch requnes e-winding and, fun ther, it illustrates
a star stop work hitted to the up and down which prevents the same being over-
wound.
Fig. 2 is a sectional portion taken through the going barrel axis and its ratchet
and upon the dotted line 2, Fig. 1, whilst
Fig. 3 19 a part section on the dotted line 3, Fig 1, though the intermediate
wheel and its stem
Fig. 4 is a back view of the watch movement without its case from the top plate
side. This view illustrates the separate winder stems of the going barrel and the
up and down, whilst
Fig. 5 is a view on a smaller scale illustrative of the dial with the position of the
indicating up and down fingui.
The same letters of reference indicate corresponding parts in Figs 1-5.
a is a watch casing, within the hollow interior of which is hinged and fitted a
movement a², faced with a dial a³, and which said movement compuses a running
down time mechamısın and an up and down indicating mechanism as heremafter
described. The mechanisms which constitute the watch movement are located
between a pillar plate a, and a top plate a', the one being connected to the other
by means of distance pillars us, and are carried by them.
Mounted transversely through the pillar plate at is the hollow ai bor ³ of a ratchet
01 atcbet wheel b, whose hollow axis 19 augularly formed to receive a like angulai
end of a stein c, on which is mounted a going bariel d, within the interior of which'
15 located the main spring. This said ratchet wheel works against the outside face
of the pillar plate and is free to 10tate within its bearing 65, formed within the said
plate, and is provided with a click or pawl, and a spung bº, and 18 kept in its
BSigned position by a bar or cock b'.
The other end of the stem e takes its bearing within a name plate a', attachedly

page_text: connected to the top plate a, and is squared to fit a key for the purpose of winding
the running-down tiine mechanism.
The said going banel d, whose periphery is formed with teeth, is connected
or in gear with the teeth of an intermediate wheel e, whose hollow arbor e² is mounted
within bearings e, in the top plate and pillar plate respectively, and which said
hollow arbor is made solid or fast with the intermediate wheel e, and carries the
same.
is a toothed pinion on the hands axis or arbol e, which gears with the teeth of
the ntermediate wheel e as aforesaid, and e' is the centre wheel made fast with the
pimon e, and which said centre wheel e' is toothed ou its periphery and geais into
and dives the thud toothed pinion e, having made fast with it the thud toothed
wheel e, which, in turn, dives the fourth toothed pinion el, having made fast with
it the fourth wheel el, which also, in its turn, gears with and dives the escape
wheel pinion e, and thus communicates motion to the escape wheel e3 which is
controlled by a lever pallet in the ordinary manner. This train of wheels consti-
tutes the running-down mechanism, and their arbors take then bearings within either
the pillar on top plate, or a cock or bar and the top plate, and by which they are
cairied.
Passing through the hollow interior of the intermediate arbore is a stem f
provided with an angular part 7%, and a encula part f³, which said cucular part
fits the interior of the hollow ai bor e friction tight, and has made fast with it and
eamed on the pillar plate side a disc f, having integial with it a finger ƒ³ and a
pinion, which latter gears with and drives a toothed wheel f', whose arbor or
axis is planted within the middle of the pillar plate a', and which said wheel f
dives another toothed wheel g, mounted upon a pivot y fast to and standing up
from the pillai plate as aforesaid, and which said wheel caries an up and down
Indicating huge g³ (shown in Fig. 5) for the purpose of notifying to the owner of
the watch that the same has run down and requies ie-winding.

Fitted and working on the top face of the pillar plate a is a star wheel h, free to
move on its centre pin 2, and piovided with projecting teeth ³, and spaces *, but
one tooth being differentially shaped to the others, and to the spaces of this
wheel the finger fo of the finger discf gears It will be seen from the drawing that
the peripheries of four teeth of the star wheel are made to fit the cicular
periphery of the finger disc, but the fifth tooth is shaped differently, and will
not pass the periphery of the finger disc, and so constitutes a stop and prevents any
further rotation of the disc in a winding-up direction.

The time mechanism and the up and down indicating means are wound up
independently of each other but un down together from the same source of cuergy.
To wind up the time meebauisin the key is inserted on the angular stem cand
turned to the left, which rotates the said stem and ratchet wheel and winds up the
spring enclosed within the interior of the going bariel, the return of the ratchet
wheel and the unwinding of the sping being prevented by the click and its
spring 26

Assuming the time mechanism has been fully wound the key is uscited on
the angular post of the stem, the same tuined, and, through the medium of
the finger disc fand its finger 15, and also the toothed pinion 6, movement is
communicated to the star wheel h, and the toothed wheel ' respectively, and
which said toothed wheel communicates motion to the wheel g which carries the
finger g A free rotation of the pinion can be made so long as the teeth h³
of the stop wheel / come in the path of the periphery of the finger disc, but
duectly the large tooth f³ meets the periphery of the finger disc a dead lock or
stop of the winding or setting 18 effected. It will be understood that the huger
dise can rotate four times to one rotation of the star wheel. On the time mechanism
running down the intermediate wheel carries round with it the frictionally fitted
stem by which, through the pinion and the finger disc f, the indicating parts
are brought back to the normal or unwound position.
By using an improved construction of ratchet wheel such as b, as set forth,

page_text: a going barrel and its stem can be removed for repairs without interfering whatso-
ever with the said ratchet wheel and, further, by my improved construction of
intermediate wheel which I have just described I am enabled to work off the same an
up-and-down indicating meaus and also a star stop work. Instead of the inter-
mediate wheel being constructed with a hollow arbor, the same may have a solid
aibor, which said arbor would be frictionally fitted within the hollow nave of the
intermediate wheel
Fig 6 represents a watch movement without its case constructed according to
a modified forin of the third part of my invention, and also a means for setting the
hands from the back of the watch according to the fourth part of my invention.
Fig. 7 is a section of a portion of the movement shown in Fig 6 on the dotted
line 4, whilst
Fig 8 is the same movement as Fig 6 but looking from the top plate side.
This watch movement comprises an up-and-down arranged in a position directly
opposite 3.0 o'clock on the dial, and is in communication with the going barrel in
such a manner that on the winding up of the going barrel the indicating up-and-
down mechanism is also wound up from the same stem and, further, a means
whereby, with the use of my improved intermediate wheel as previously described,
the hands can be set from the back or the top plate side of the watch movement.
In the coupling of the up-and-down to the going barrel for winding, an improved
arrangement is used, whereby I can effectively and automatically couple and
separate the said movements one to or from the other through the instrumentality
of the main spring
a is the said movement which is confined between and upon the sides of the
pillar plate a, and the solid top plate a distanced by pillars do. A going barrel d
is fitted to a stem c, and has teeth d upon its periphery which gear into and
duve an intermediate wheel e, mounted friction tight upon a hollow arbor e²,
which has made fast with it a driven toothed wheel fou the top plate side, and
a pon on the pillai plate side, which latter meshes with a toothed wheel g,
caying on its albo g³ an up and down indicating hand like to the one described
and shown in Fig. 5.
Disposed on the top plate side as and fast on the stem c of the going barrel &
is a driving toothed wheel h which geais into and dives an intermediate coupling
ratchet wheel z, whose arbor takes its bearing and works in a quadrant slot 13
in the top plate, as aforesaid, and which said coupling and ratchet wheel is pro-
vided with a chick or pawl, Jointed to the top plate at 12, and provided with.
a spung, for the purpose of preventing the return of the main sping enclosed
within the going bariel d after being wound. The said coupling wheel
automatically taken into mesh with the toothed wheel on the hollow ai bor e³,
by the direction of rotation of the wheel h, through the medium of the slot 3,
and is automatically taken out of mesh directly winding ceases by the energy of
the main spring enclosed within the going bariel
is
Passing through the hollow interior of the intermediate wheel arbor is a hand
setting stem k, squared on its top plate end to receive a key, and on its 'other
end carries a toothed pinion 2, which gears into and drives an intermediate toothed
wheel 3, arbored at in the pillar plate, and which said toothed wheel meshes into
and dives the canon pinion m, made fast upon the centre stem m², upon which one
of the bands of the watch is carried. The running down tiain of wheels, which receive
then movement from the intermediate wheel, are not shown in the diawing but are
identical with that shown and described in Fig 1. When winding up this move-
ment the key is placed upon the square of the stem of the going barrel d which,
in its movement, carries round the driving wheel in the direction shown by the
arrow in Fig 8, which causes the coupling wheel to mstantly mesh with the
driven toothed wheelf made fast upon the fiction tight hollow arbor e oE
the intermediate wheel e and, so long as the winder stem c is turned, motion will
be communicated by the pinion to the wheel g and its indicating up-and-down
finger, which will receive a movement of one rotation for the full winding, but

page_text: immediately the power of winding is taken from the stem e the energy stored u›
in the wound-up spring with the going bairel d asserts itself, and throws out
of gear the coupling wheel from the driven wheel, which is essential to allow
the time mechanism to run down To set the hands from the back of the watch
the key is inserted on the square of the stem k, which is fiec to move within the
hollow arbor 2, and, on being turned, a rotary movement is given to the pinion
which in tuin dives the wheel 3 and through it the piuion in on to whose niboi
one of the hands are carried On the time mechanism tunning down the intel-
mediate wheel e will carry round with it its friction tight hollow at bor e, and
also the wheel and the pinion e, the former being now an idle wheel, but the
latter will dive round in a reverse direction the toothed wheel g with its up and
down indicating finger.
Thus it will be seen that through my improved intermediate wheel I am enabled
to set the hands from, the back of the watch and, with the help of the coupling
wheel, wind up or set the up and down indicating means at the same time as the
winding of the time mechanism. I wish it to be observed that in this movement
the top plate is a solid one for the purpose of carrying the winding wheels as
described.
Fig 9 represents a movement constructed according to the fifth or last part of
my invention and has, for its object, to enable a going barrel watch to be wound
This view illustrates the movement
up from the same position as a fuzee watch
from the pillai plate side, whilst Fig 10 illustrates the same from the top plate
side, and Fig 11 is a cross section of a portion of the said movement on the dotted
line 5.
In this aangement as the pillar plate and a is the top plate of the
movement a², of which e is the intermediate toothed wheel, having a hollow
abor e integial with it, and which said intermediate wheel meshes with the teeth
of the going barrel d, mounted upon a solid at bo c, which causes on the pillar plate
side a ratchet wheel, provided with a click f, and a sping f³, and which said
wheel gears into and is duiven by a coupling wheel, arbored at c to the pillar plate,
the said wheel receiving its motion from a toothed driving wheel h, made fast upon
a winding stem k, passing through the hollow interior of the intermediate wheel
aibo, and which said winder stem is located in the same position as the winder
stem of a fuzee watch and, though the intervention of the wheels h, 1, and f,
communicates its movement to the spring confined within the hollow intetion of
the going barrel d
It will be seen that by the use of my improved intermediate wheel I am enabled
to wind up a going barel watch from the position of a fuzee watch which has
hitherto been unaccomplished and, further, I am enabled to repair certain parts of
the mechanism without interfering with others
It will also be noticed that the winding anlangement just described is carried on
the pillar plate but it may, if necessary, be cared on the top plate of the
movement, thus forming a perfect combination between the banel and
intermediate wheel
I wish it to be understood that the running down mechanism will be essentially
the same in this case as in the one descubed and illustrated in Fig. 1.
The chief object of these improvements are adaptability, simplicity m then
attachment and detachment for iepas, simplicity of constinction, cheapness in
production, and are carried out in a spit of economy.
Instead of the intchet wheel on the going barrel axis being kept in by a bai or
cock, the same may have formed upon its ai bor a shoulder which will prevent its
removal.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what mannei the same is to be performed, I declare that what I
claim is
