PROVISIONAL SPECIFICATION.
Improvements in Watch Pendants.
I, FRANK GEORGE FAXON, of Mount Morris, in the County of Livingston,
and State of New York, United States of America, Gentleman, do hereby declare
the nature of this invention to be as follows:-
My invention relates to improvements in watch case pendants of the kind for
which former Letters Patent of the United Kingdom were granted to me dated
March 5th, 1889, No. 3880; and it has for its object first to lessen the cost of
manufacture whilst affording an equally secure and durable connection for the ends
of the bow combined with facility of adjustment for wear of the bow-ends and their
bearings.
My invention is designed to reduce the amount of precious metal, used in the
construction of the pendant, to a minimum and yet afford ample bearing surface for
the ends of the bow. This I accomplish by constructing the pendant of a "capsule "
or shell of precious metal and providing bushings or filling pieces of base metal
which constitute the bearings for the bow, the capsule being used merely to contain
and conceal the filling pieces or bushings which are securely united or held in place
therein by the means hereafter described. In all cases these bushings are divided
in a transverse plane coinciding with the axis of the bow journals, the upper and
lower bushings being each formed with half-round cavities in their adjacent faces
corresponding to, and forming bearings for, the ends of the bow, which are thereby
securely retained, these adjacent faces of the bushings being separated by a sufficient
interval to allow of adjustment of the bushings for wear. These bushings are
firmly united and held in position in the capsule or shell by a central tubular bolt
or sleeve screwing into the neck of the pendant or into a nut within the rim of the
watch case and bearing, either by a head or by a nut screwing on its upper end, on
the top of the upper bushing. This tubular bolt or sleeve affords passage for the
winding stem and may be slotted to receive the springs or stop by which the
engagement of the winding stem with the hand-setting mechanism is controlled in
certain cases.
According to one arrangement, in which the winding stem is not drawn out for
engagement with the hand-setting mechanism and in which the pendant is, therefore,
not provided with special means of retaining the winding stem in its different
positions, the capsule or shell of the pendant is cup-shaped and in one piece having
holes at opposite sides for the passage of the bow ends, which are sprung through
the said holes and are secured by ribs on the bearings in the upper filling piece
engaging with circumferential grooves or necks turned in the bow ends. In this
case, the parts are secured together as follows; The lower filling piece having
been inserted in the capsule, the bow ends are sprung, through the holes in the
capsule, into place in the bearings of the filling piece, the upper filling piece is then
inserted and the ribs in its bearings engaged in the necks of the bow ends, and the
said filling pieces secured either by a screwed sleeve passing through them and
screwing into the neck of the pendant or into a nut in the watch case rim, the head of
the sleeve or a nut thereon bearing on the upper filling piece. Or the sleeve may be
dispensed with and a cap-piece screwing into the upper part of the capsule itself
may screw down
the
проп upper filling piece. In either case, notches are provided
in the periphery of the head or nut or cap-piece into which a pointed instrument
is introduced through a hole in the side of the winding knob for screwing up or
unscrewing the parts without removing said knob.
According to another arrangement (in which springs engage with grooves in the
winding stem and are locked by the ends of the bow abutting against them and

page_text: unlocked by turning down the bow so as to bring notches in the ends of the bow
opposite to the heads of the springs, as described in my previous Patent aforesaid)
the bow-ends have enlarged ends and have their bearings in bushings contained in
a capsule or shell, as before, but the capsule is made in two parts, the line of
division being in a transverse plane coinciding with the axis of motion of the bow
journals, the joint being disguised by external beads turned on the capsule. This
division of the capsule is necessary to allow of the enlarged ends of the bow being
inserted, and, in order to strengthen this joint in the transverse direction, the
division between the bushings does not coincide with that between the two parts of
the capsule except at points immediately adjacent to the bow journals, the adjacent
faces of the bushings being on slightly inclined planes, so that the one bushing will
cross the joint of the capsule, the bearings of the bow journals being, however, of
equal depth in both bushings. The upper part of the capsule merely fits friction
tight on the upper bushing, so as to permit of adjustment of the latter to take up
wear. The central sleeve screws into the pendant neck or nut in the case rim, as
before, but it is necessarily screw-threaded at its upper end to receive a nut which
bears on the upper bushing. To prevent the sleeve turning in its seat, when
screwing up the nut, the middle part of the sleeve is of enlarged diameter and has
flats on it against which abut the enlarged ends of the bow ends.

COMPLETE SPECIFICATION.
Improvements in Watch Pendants.
I, FRANK GEORGE FAXON, of Mount Morris, in the County of Livingston, and
State of New York, United States of America, Gentleman, 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 watch case pendants of the kind for which former Letters
Patent of the United Kingdom were granted to me dated March 5th 1889,
No. 3880; and it has for its object to lessen the cost of manufacture whilst affording
a secure and durable connection of the bow to the pendant combined with facility
of adjustment for wear.
My invention is designed to reduce the amount of precious metal in the watch
pendant and yet afford ample bearing surface for the ends of the bow.
This accomplish by constructing the pendant of a capsule" or shell of
precious metal and providing upper and lower bushings of base metal which fill the
"capsule" and constitute the bearings for the bow, and are secured in place by
means of a tubular bolt or sleeve giving passage to the winding stem. These
upper and lower bushings have half-round cavities in their adjacent faces forming
bearings for and securing the ends of the bow, provision being made for the
adjustment of the bushings for wear.
Reference is to be had to the accompanying drawings, forming part of this
Specification, wherein
Figure 1 is a central vertical section of the improved pendant, in the plane of the
bow, one end of the bow being broken away.
Figure 2 is a face view, and Figure 3 a vertical section, of the upper bushing.
Figures 4 and 5 are similar views of the lower bushing.
Figures 6 and 7 shew a modification, in which the capsule or shell is divided.
The same letters of reference indicate the same parts in all the figures.
a is the neck of the pendant and the cup-shaped body of the gold capsule or
shell of the pendant made integral with the neck a and containing the bushings d d
which fit therein, the shell having holes c and the bushings having bearings d² for
с

page_text: the ends of the bow e. The latter have necks f turned in them, with which engage
ibs g on the bearings of the upper bushing, after the bow ends have been sprung
hrough the holes c. The lower bushing d is permanently secured in the capsule of
the pendant, by swaging or burring the capsule, as at d*, into a circumferential
groove in the bushing after the latter is inserted, or by soldering, or otherwise, and
the upper bushing d¹ is secured after the insertion of the bow ends in their
bearings, by a bolt made tubular to give passage to the winding stem i and
bearing by its head on the upper bushing d¹ and screwing into the lower bushing d,
as shewn, or it may be into a nut in the watch rim, if preferred. The adjacent
faces of the bushings are not in contact, but are separated slightly so as to allow of
taking up wear of the bow journals and bearings.
If the bow ends have enlarged heads (as in my previous Patent aforesaid) so
that the bow ends cannot be sprung into their bearings through the holes in the
capsule or shell as before, the capsule is made in two parts bb, as shewn in
Figures 6 and 7, the line of division being in a transverse plane coinciding
with the axis of the bow journals, and in order to strengthen this joint in the
transverse direction, the division between the bushings d' does not coincide
with that between the two parts of the capsule (except at points immediately
adjacent to the bow journals) so that the one bushing, d for instance, will cross
the joint of the capsule. The bearings of the bow journals are, however, of
equal depth in both bushings which are separated a slight distance as in the
other case, while the two parts of the capsule make a butt joint (which is
disguised by beads turned on the capsule) the upper part & merely fitting
friction tight on the upper bushing so as to permit of adjustment of the latter
to take up wear.
The tubular bolt or sleeve screws into the lower bushing
(which is permanently secured in the lower part of the capsule or shell as
before) and the tubular bolt or sleeve may have a nut screwing on its upper
end instead of a head.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I would observe that I
make no claim to a pendant capsule, per se, but I declare that what I claim is ;-
1. In a watch pendant, the combination, with a capsule or casing, of upper and
lower bushings having bearings in their adjacent faces, those of the upper bushing
being adapted to engage with necks in the bow journals, and of a tubular bolt
giving passage to the winding stem and uniting the two bushings, substantially as
specified.
2. A transversely-divided watch pendant, constructed of a capsule or casing
made in two parts forming a butt joint at the plane of the bow journals, in combina-
tion with bushings fitting therein and having bearings adapted to engage with the
bow journals, the division between the bushings "breaking joint" with the division
between the two parts of the capsule, and of a tubular bolt uniting the bushings
and giving passage to the winding stem, as specified.
