PROVISIONAL SPECIFICATION.
An Improved Winding Mechanism for Watches.
I, GEORGE JOHN ORAM, trading as George Oram and Son, of 19 Wilmington
Square, Clerkenwell, in the County of London, Watch Manufacturer, do hereby
declare the nature of this invention to be as follows:-
My invention relates to an improved English automatic winding watch, which
consists of mechanism operated on by the opening and closing of the front of the
case to wind up the main spring in the drum or barrel.
This invention is constructed as follows:-
On the barrel arbor I place a lever geared to a ratchet with a double spring-
click. In any convenient position, I pivot a curved lever the end of which is
connected by an arm or link to the end of the lever on the barrel arbor. On or
near the centre of the curved lever I pivot a projecting arm the end of which
projects or slides out against the hinge of the case when the case is opened giving
a slight turn to the lever on the barrel arbor; by closing the case it forces the
projecting arm inwards and thereby causes the lever on the barrel arbor to operate
on the rachet of the barrel in order to wind the spring. When the spring in the
barrel is wound up the mechanism is thrown out of gear.
It will be understood that the foregoing is given by way of illustration and that
the shapes, materials and proportions of the parts may be varied in many ways
within the scope of my invention.

COMPLETE SPECIFICATION.
An Improved Winding Mechanism for Watches.
1, GEORGE JOHN ORAM, trading as George Oram and Son, of 19 Wilmington
Square, Clerkenwell, in the County of London, Watch Manufacturer, 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 an improved English automatic winding watch, which
consists of mechanism operated on by the opening and closing of the front of the
case to wind up the main spring in the drum or barrel.
I attain this object by the mechanism illustrated in the accompanying drawing,
in which-
-
Fig. 1 is an elevation of the watch with the dial removed;
Fig. 2, is a view of the ratchet fixed to the lever;
Fig. 3, is a view of the top of the drum.
Similar letters refer to similar parts throughout the views.
This invention is constructed as follows:-
On the barrel arbor I place a lever g fast to a ratchet; with a double spring
click P and 9. In any convenient position, I pivot to a stud a curved lever or
rock-shaft e on the frame i the end of which is connected by an arm or link to the
end of the lever g on the barrel arbor. On or near the centre of the curved
lever or rock-shaft e I pivot a projecting arm d the end of which projects or slides
out against the hinge of the case and is pivoted to the jaws of a block c attached
to the hinge b; and when the cover a of the case is opened it gives a slight
Q/1

page_text: turn to the lever g on the barrel arbor, and by closing the cover a of the case hit
forces the projecting arm d outwards and thereby causes the ratchet j under the
lever g on the barrel arbor to operate on the ratchet of the barrel n in order to
wind the spring. When the spring in the barrel is wound up the mechanism is
thrown out of gear by means of a stud m fixed to a wheel / coming in contact with
the block o which forces the double spring-click away from the ratchet j.
It will be understood that the foregoing is given by way of illustration and that
the shapes, materials, and proportions of the parts, may be varied in many ways
within the scope of my invention.
Having now 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 is :-
1. In winding mechanism for watches, the combination of the mechanism operated
on by the opening and closing of the cover of the case to wind up the main spring in
the drum or barrel, substantially as described.
2. In winding mechanism for watches, the combination of a lever and ratchet on
the barrel arbor connected to the curved lever or rock-shaft pivoted on a stud by
a link, and the projecting arm pivoted to the block on the hinge and the curved
lever or rock-shaft, substantially as herein described and for the purpose specified.
3. In winding mechanism for watches, the combination of a stud pin fixed to a
wheel on the barrel and the block which forces the double spring-click out of gear
when the spring in the barrel is wound up, substantially as herein described.
