PROVISIONAL SPECIFICATION.
Improvements in Watches.
We, THOMAS PETER HEWITT and CHARLES JAMES HEWITT, both of The
Prescot Watch Factory, Prescot, in the County of Lancaster, Watch Manu-
facturers, do hereby declare the nature of this invention to be as follows :-
The object of this invention is to cheapen the manufacture of watch movements
to secure a thicker chain by doing away with the fusee cap and forming a bolt of a
piece stamped out of a plate that will be held in place by the spring itself instead
of having the cumbersome eye piece and screw taking up space.
On the winding arbor, we place a pinion gearing into a large spur wheel which
has the space between two teeth filled пр solid. When the pinion arrives at this
point it jams and shows that the watch is wound up and prevents it being wound
too far.
On the arbor of the spur wheel is a pinion gearing into a larger wheel on the
arbor of the hand opposite the second hand, known as the up and down hand,
indicating whether the watch is wound and if so how much more it has to run.
The apparatus could be further modified in other ways, such for instance, as
using an entire wheel, but placing a stop on it to come against a stationary object or
against an arm on the winding arbor.
The bolt is stamped out of a plate and consists of the ordinary bolt with a pin
instead of the eye or screw hole. A notch on the pin holds the spring and as
both bolt and pin slide in the frame no screw is required, the spring itself
preventing the bolt from coming out. The pin could be of any section and the
spring could go through a hole in it instead of a notch.

COMPLETE SPECIFICATION.
Improvements in Watches.
We, THOMAS PETER HEWITT and CHARLES JAMES HEWITT both of The
Prescot Watch Factory, Prescot in the County of Lancaster, Watch Manu-
facturers, 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 object of this invention is to cheapen the manufacture of watch movements
to secure a thicker chain by doing away with the fusee cap and forming a bolt of a
piece stamped out of a plate that will be held in place by the spring itself instead
of having the cumbersome eye piece and screw taking up space.
It is best described by aid of the accompanying drawings, in which :-
Figure 1 shows diagrammatically the winding apparatus:

page_text: the pinion arrives at this point, it jams and shows that the watch is wound up and
prevents it being wound too far. On the arbor of the-spur wheel C is a pinion F
gearing into a large wheel J on the hand opposite the second hand, known as the
up and down hand, indicating whether the watch is wound, and, if so, how much it
is run down.
The apparatus can be further modified in other ways, such as, for instance, by
using an entire wheel C and placing a stop G to come against a stationary object
or against an arm H on the winding arbor A, as in Figure 1, or against the
winding arbor itself, as in Figure 5. In actual practice, we have found it better
not to fix the stop to the wheel, but to support it on a stationary pivot K and
having a pin in it E, working in a slot in wheel C. This device has grown out of
our original idea as set forth in Figures 5 and 6. We have, therefore, illustrated it
in the accompanying drawing.
Referring now to Figures 2, 3 and 4 :-
The bolt L is stamped out of a plate, and consists of the ordinary bolt with a
pin M instead of the usual eye or screw hole. A notch N on the pin holds the
spring O, and, as both bolt and pin slide in the frame, no screw is required, the
spring itself preventing the bolt from coming out. The pin could be of any section
and the spring could go through a hole in it instead of a notch. P is a plate
screwed to the plate holding the bolt in place.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
1. The winding device substantially as described, and illustrated in Figures 5
and 6, whereby, when the winding has arrived at a given point, a mechanical stop
stops all further winding and thus it is impossible for the winder to put a strain on
the spring.
2. The arrangement of bolt and its appurtenances substantially as herein
described
ribed
