An Improvement in Going Barrel Watches and Clocks.
I, FREDERICK CHARLES WHITE, of 35, 36 and 37 Cow Lane, Coventry,
Warwickshire, Watch Manufacturers Manager, 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 has reference to those going barrel watches and clocks in which
the going barrel is arranged to be removed without taking off the dial or hands
and my invention consists of the hereindescribed improved and simplified
arrangement of the click work of the going barrel.
In carrying out this invention I sink the ratchet wheel and click and its spring
in a recess in the front of the front plate of the watch or clock and there secure the
ratchet wheel by a metal ring fitting in the said recess as I will now fully describe
by referring to the accompanying drawings which illustrate my invention applied to
a going barrel watch.
Fig. 1 is a back view and Fig. 2 is a front view of a portion of a watch having
its going barrel fitted with click work constructed and arranged according to this
invention and Fig. 3 is a side view of the same; Fig. 4 is a front view on an
enlarged scale of a portion of the front plate with the metal ring removed so as to
shew the ratchet wheel ratchet and spring; Fig. 5 shews the ratchet wheel
separately and Fig. 6 represents in elevation and section the metal ring which holds
the ratchet wheel in place and Fig. 7 is a cross section on the arbor of the going
barrel. Figs. 5, 6 and 7 are drawn to the same enlarged scale as Fig. 4.
The same letters of reference indicate the same parts in all the figures of the
drawing.
A is the going barrel and is the arbor of the same turning in bearings in the
front plate C and in the removable plate D as in some other watches and made
with a square end to engage in a corresponding square central hole e in the
ratchet wheel E. I sink the ratchet wheel E in the recess f¹ which I form in the
front of the front plate C this recess f¹ being almost circular and continued side-
ways at and then undercut at f³ into the front plate C for the click J and its
spring K to fit in the said click J turning on the screw j in the front plate C.
This is clearly shewn by Figs. 4 and 7. The spring K is fixed at one end to the
plate C by a screw see Fig. 4. The recess is made a little larger in diameter
than the ratchet wheel E so as to allow of the latter turning freely. Fitting in the
larger circular recess in the front plate C which recess is concentric with the
ratchet wheel E 1 provide a metal ring H (which is shewn separately by Fig. 6)
which covers the teeth of the ratchet wheel E and the click J and spring K and
fits against the face of the ratchet wheel so as to secure the same in place this
ring H being secured by the two screws which pass through the ring and into
the front plate C. The ratchet wheel E has a boss e² on its front side of a size to
fit in the ring H which latter thus forms a bearing for the ratchet wheel. The
ring His shewn fixed in position in Figs. 2 and 7 but in Fig. 4 the ring H is
removed so as the better to shew the click work underneath. It will be seen that
the ratchet wheel E and plate H and click work are all recessed into and flush with
the front of the front plate C and thus are not in the way of the dial and that by
first removing the cover plate D the going barrel A and its arbor bare free to be
removed without disturbing the click work or the dial and fingers.
My invention is applied to going barrel clocks similarly as above described with
reference to going barrel watches.

page_text: 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 :-
In going barrel watches and clocks the improved arrangement of click work for
the going barrel the said click work being recessed into the front of the front plate
and there secured by the metal ring H all substantially as herein before set forth
and shewn upon the accompanying drawings.
Dated this 31st day of January 1894.
