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 first to keyless watches of the kind in which the winding stem is
put into operative connection with the hand setting mechanism by slightly drawing out
the said stem from the pendant previous to rotating it for the purpose of setting the hands.
This kind of hand setting mechanism I have, for the sake of brevity, hereinafter referred
to as a "pendant set to distinguish it from the more common form in which the hands
are otherwise set.
The object of my invention is first to construct a pendant set in which the watch
bow will retain the winding and setting stem within the pendant when in its normal
position, but which will release the stem-holding springs when the said bow is
in a particular position. This part of My Invention consists in the combination with
a pendant made in separable parts, of a bow having conical recessed ends received in
bearings formed in the parts of the pendant and springs arranged to engage the
winding and setting stem and adapted to be locked by the ends of the bow. The
object of my invention is further, to provide a pendant and bow for watches in which
the bearing of the bow and pendant will be held in such a manner as to render it
impossible to accidentally detach it from the pendant.
This part of My invention also consists in the combination with a pendant formed
of two parts and provided with spheroidal or spherical cavities, of a bow provided
with spherical or spheroidal ends, the parts of the pendant being adjustable to take up
wear, all as hereinafter more fully described.
Reference is to be had to the annexed drawings forming part of this specification,
in which figure 1 is a vertical transverse section of a watch pendant to which my
first improvement has been applied, shewing the parts in position for drawing out the
winding and setting stem, the section being taken on line figure 4.
Figure 2 is a vertical transverse section also taken on line a a figure 4, showing the
winding, and setting stem partly withdrawn from the pendant. Figure 3 is an

page_text: enlarged perspective view of the stem-holding springs. Figure 4 is a transverse
section taken on line y y figure 1. Figure 5 is a sectional face view of one end of the
watch bow, showing the end received in the pendant. Figure 6 is a front elevation
of another form of my improved watch bow and pendant. Figure 7 is a vertical
section of the same. Figure S is a detailed side elevation of the bow.
Figure 9 is a plan view of the nut for holding the parts of the pendant together;
and figures 10 and 11 represent in section respectively the upper and lower parts
of the pendant.
Referring to figures 1 to 5 To the watch rim A is fitted the pendant B formed of four
parts, the main portion a screwed into the rim A, the sleeve & screwed into the part a,
the ring e placed loosely on the sleeve and the nut d screwed on the outer end of
the sleeve band clamping the ring c. The part a of the pendant is bored to receive the
winding and setting stem and is provided with a shoulder e upon which rests the
annular portion of the double spring D. The annular portion of the said spring
supports the spring arms which are provided at their free ends with heads h. The
sleeve is provided with longitudinal slots in diametrically opposite sides for
receiving the spring arms g. The ring c which is fitted to the outer end of the sleeve b
is preferably made of the same diameter as the upper end of the part a and in the
upper surface of the ring is formed a conical recess to which is fitted the conical nut d
which holds the ring in position upon the sleeve b. Both the nut and sleeve are
provided with nicks for receiving a screw-driver.
The bow E is provided with enlarged conical ends E' which are received in the
conical bearings of the pendant B. The end faces of the adjoining ends of the
bow E, are parallel and in the said faces are formed recesses k of sufficient size to
receive the ends of the heads of the springs g when the said springs are thrown
outward by the collar I during the longitudinal movement of the winding and setting
stem C. The stem C is reduced in diameter in two places, leaving the collar which
is provided with beveled faces to facilitate its passage between the ends of the double
spring D. The outer end of the stem is provided with the usual crown F and the
inner end is squared for engagement with the winding and setting mechanism. The
stem is also provided with the collar m for limiting its outward movement. The
collar of the stem C is engaged by the heads of the spring arms g which thereby
preventing the drawing out of the said stem, but except when the bow E is turned so
as to cause the recesses in the ends of the bow to coincide in position with the
heads of the spring. the The stem may then be drawn out for the purpose of
setting the watch, the beveled faces of the collar pressing the arms g of the double
spring D outward, as shown in figure 2, the heads being partly received in the
recesses k. My improvement prevents the accidental drawing out of the stems () and
permits of the use of light springs for retaining the stem in either of its positions, so
that when the bow E is in a certain position the said stem may be readily drawn out
or pushed in. It is obvious that a single arm g of the spring D will serve to hold the
stem C in either of its positions and that in such a case only one end of the bow E
would need to be recessed. It is also obvious that by omitting the groove below the
collar; the spring arms g will be compelled to remain in an expanded position so long
as the said stem is pulled out. This will lock the bow E so that it cannot be turned
until the stem is returned to its normal position. This modification is important in
hunting case watches, in which case the how is made to fold down over the bezel
before the stem can be pulled out, thus making it impossible to close the watch
without first releasing the stem C and pushing it in. For this reason, I do not limit
or confine my invention to the exact form shewn. This improvement renders it
possible to remove the winding stem C from the pendant after taking out the sleeve b
and spring D.

The pendant shewn in figures 6 to 11 inclusive, is a simple adjustable pendant formed
of the parts A B₁, the part A being provided with a sleeve g¹ over which the part B¹
is fitted, the division line of the parts A' and B¹ being on a plane at right angles to
the axis of the pendant. In the adjacent surfaces of the parts A and B₁ at diametri-
cally opposite sides of the axial line of the pendant are formed spheroidal cavities f¹
.

page_text: in which are fitted the spheroidal ends c¹ of the bow C³, said spheroidal ends being
separated from the bow by necks c² of smaller diameter than the bow. The part A
of the pendent is provided with a rim j¹ to which the periphery of the part B' is fitted
so that the space between the said parts A' B₁ will be invisible. The part B' is
counterbored in its upper surface to receive the nut D' which screws upon the threaded
end of the sleeve g₁. The pendant is provided with the usual winding stem H' which
passes through the sleeve g¹ and through the part A¹. When the bow C¹ becomes
loosened, it may readily be tightened after removing the winding stein H' by turning
screwing down the nut D'. It is obvious that in lieu of the spheroidal ends,
employ spherical, or even cylindrical, ends and therefore, I do not confine myself to
the exact form and arrangement hereinbefore described.

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 lay no
claim to the use of springs engaging with a collar on the winding and setting stem, my
invention in regard to the pendant "set" consisting essentially in applying the ends of
the bow to lock and release the said springs, as herein described, and I declare that what
I claim is :
1. In a pendant set for watches, the combination with the winding and setting stem,
of one or more springs arranged to hold the stem in position for setting or winding
the watch and of a lock constituted by the ends of the bow for holding the said spring
or springs in engagement with the winding and setting stem, substantially as
specified.

shoulder e, the ring c, the sleeve b, and nut d, and the bow E, substantially as
specified.
