page_text: I, FELIPE HECHT, of 12, Rue du Rhone, Geneva, in the Republic of Switzerland,
do hereby declare the nature of this invention to be as follows:
The object of the invention is to facilitate to a great extent the repairing of the
wheel-work of watches, without taking them out of their cases, and particularly
to allow of the removal of the barrel without having to take the works out of the
case and altogether without removing any other portion of the said works.
In the accompanying drawing which shows by way of example, a watch con-
structed according to the present invention.
Figure 1 is a plan view of the wheel-work,
Figure 2 is a plan-view of the barrel-bridge with click-spring.
Figure 3 is a plan-view of the crown-bridge, and
Figure 4 shows to an enlarged scale a vertical section on the line -y-z of
Figure 1.
The spring-barrel is independent; its bridge B is secured to the plate A by
means of a single screw band of the two usual studs. The crown-bridge C is
secured upon the plate A by means of one screw c, passing through the crown-
wheel and securing it to the plate, and of the two usual studs.
In order to remove the barrel it is only necessary to unscrew the screw b from
the spring-barrel-bridge and the barrel may be taken out without removing any
further portion of the works. The crown-bridge is usually secured to the plate
by means of at least two screws, but in my improved system the crown-screw c
passes through the crown-bridge C so as to be screwed directly into the plate A
while securing at the same time the crown-wheel c¹. By removing the crown-
screw I am thus able to take out the crown-wheel c¹ as well as the crown-
bridge C.
The click-spring D assuming a particular shape is sunk into a recess provided
in the spring-barrel-bridge B, and kept in its place by means of the pin d. The
shape of the said spring D will allow a good recoil of the click to take place and
the nose of the latter will prevent it from engaging into the teeth of the
ratchet R more than is strictly necessary, which enables the ratchet R to be put
in place without previously compressing the click D as is necessary in other
watches.
The bridge M of the centre-wheels is also secured by means of a single screw m
and of the usual studs, as are also the bridges N of the escapement-wheel and the

page_text: bridge O of the balance wheel. The bridges M and N may be joined so as to form
one bridge only which would be secured by means of the screw m.

I, FELIPE HECHT, of 12, Rue du Rhone, Geneva, in the Republic of Switzerland,
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 follow-
ing statement:
The object of the invention is to facilitate to a great extent the repairing of the
wheel-work of watches, without taking them out of their cases, and particularly
to allow of the removal of the barrel without having to take the works out of the
case and altogether without removing any other portion of the said works.
In the drawing left with my Provisional Specification which shows by way of
example, a watch constructed according to the present invention.
Figure 1 is a plan view of the wheel-work,
Figure 2 is a plan-view of the barrel-bridge with click-spring.
Figure 3 is a plan-view of the crown-bridge, and
Figure 4 shows to an enlarged scale a vertical section on the line x-y-z of
Figure 1.
The spring-barrel is independent; its bridge B is secured to the plate A by
means of a single screw b and of the two usual studs. The crown-bridge C is
secured upon the plate A by means of one screw c, passing through the crown-
wheel and securing it to the plate, and of the two usual studs.
In order to remove the barrel it is only necessary to unscrew the screw b from
the spring-barrel-bridge and the barrel may be taken out without removing any
further portion of the works. The crown-bridge is usually secured to the plate
by means of at least two screws, but in my improved system the crown-screw c
passes through the crown-bridge C so as to be screwed directly into the plate A
while securing at the same time the crown-wheel c¹. By removing the crown-
screw I am thus able to take out the crown-wheel c¹ as well as the crown-
bridge C.
The click-spring D assuming a particular shape is sunk into a recess provided
in the spring-barrel-bridge B, and kept in its place by means of the pin d. The
shape of the said spring D will allow a good recoil of the click to take place and
the nose of the latter will prevent it from engaging into the teeth of the
ratchet R more than is strictly necessary, which enables the ratchet R to be put
in place without previously compressing the click D as is necessary in other
watches.
The bridge M of the centre-wheels is also secured by means of a single screw m
and of the usual studs, as are also the bridges N of the escapement-wheel and the
bridge of the balance-wheel. The bridges M and N may be joined so as to form
bridge only which would be secured by means of the screw m.

Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what
I claim is:
1. A watch characterized by the combination of the spring-barrel bridge B bear-

page_text: ing the ratchet-wheel R, a screw b and a click-spring D, with a crown-bridge C
and the crown-wheel c¹ which are secured to the plate A by means of a single
crown-screw c, substantially as shown and described.
2. In a watch as specified in Claim 1, the click-spring D as shown and described.
