I, FRANCIS JAMES SMITH, of Colombo Street, Christchurch, in the Provincial
District of Canterbury, in the Colony of New Zealand, Watch Maker, do hereby
eclare the nature of this invention, and in what manuer the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This invention provides improved means of attaching the bow to the pendant of
watch.
Hitherto, the bows of keyless watches have usually been attached by springing
the ends thereof into recesses formed in the pendant of the watch.
Another method with which I am acquainted is known as Turner's in which the
ends of the bow are provided with grooved heads which pass down longitudinal
slots into recesses formed in the pendant, a filling up piece has projections fitting
into the slots and taking into the grooves upon the bow.
•
Now according to my invention, I employ a collar or socket bored to fit the
pendant and having holes to receive two pins which project radially from the collar
and opposite to each other so as to take into corresponding holes formed in the
ends of the bow.
Slots are formed in the pendant to receive the heads of the pins when the collar
is fitted upon it, and a screw passing through the collar into the pendant, prevents
the former from becoming detached.
My invention is illustrated in the accompanying drawings wherein,—
Fig. 1 is a side elevation partly in vertical central section, and
Fig. 2 a side elevation of the upper portion of a watch.
Fig. 3 a transverse section on line 3-3 Fig. 1, and
Figs. 4 & 5 enlarged detail views of some of the parts.
Similar letters indicate the same parts in all the figures.
The pendant (a) fits within the collar (b) and has grooves (c) receiving the
heads (d) of the pins (e) which have shoulders (f) fitting into corresponding holes
in the collar (b), the pins (e) fitting tightly into holes drilled in the respective ends
of the bow (g).
In fitting the parts together the bow is put into position on the collar the pins
are then severally passed through the holes in the collar (6), and into the holes in
the ends of the bow from the inside. A tapering mandril is then inserted in the
collar which drives the pins through until the shoulders thereon, take into the
holes formed for their reception in the collar.
The mandril is then withdrawn and the collar, with the bow is attached; passed
over the pendant the heads of the pins going into the grooves (c). The screw
pin (h) is then passed through the collar, and screwed into the pendant to prevent
the collar from coming off.
The bow may turn upon the pins or the pins be tight in the bow and turn in the
collar.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what I
claim is,
The means for attaching a bow to a pendant of a watch consisting in the

page_text: combination of a collar fitting over the pendant, headed pins which have shoulders
received by holes in the collar, fitting into holes formed in the ends of the bow,
the pendant being grooved to receive the heads of the pins, and a pin passing
through the collar and screwed into the pendant preventing the collar from coming
off substantially as spécified and illustrated.
