Compléte Specification Left, 1st Dec., 1888
Complete Specification Accepted, 22nd Jan., 1889
for Watches and other Analogous Purposes.
I LOUIS PLATNAUER, of Saint Pauls Square, Birmingham, in the county of
Warwick Watch Manufacturer do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in connection with the securing of the
bows or rings primarily of keyless and other watches to their pendants, but which
may also be used for securing the ends of other bows, or other such ends, capable of
such treatment, to effect their fastening under similar circumstances, and has for its
object, first to provide an improved arrangement of parts constituting means for
securing the bows or ends to their pendant or other part, and further to provide, that
such fastening shall be capable if desired, of a swivel action upon the article to which
it is secured.
I will first describe it as applied to the securing of the bow of a watch to its
pendant, without the swivelling action, in which the said bow has at its two ends, a
circular neck or groove behind a collar, which shall pass through circular openings in
the side of the pendant, and be there secured, by means of an expanding metallic
cylinder or band, having two bayonet-joint shaped slots, engaging each with the neck
at the end of the aforesaid bow; the width of the slots being equal to the diameter
of the bottom of the neck or groove.
Thus, having passed the ends of the bow through the openings in the side of the
tubular pendant, until the circular groove stands forward, within the said tubular
pendant; the expanding band is then passed down within the said pendant; the
vertical portions of the slots first engaging with the grooves or necks, until the said
necks of the bow reach the horizontal portion of the slot, when the band would be
turned round a short distance, the said neck thereby passing along, and resting in the
said horizontal portion of the slot. It will thus be obvious that the bow cannot
possibly be withdrawn, until the band has been again turned backward intentionally.

page_text: In order to further provide that this fastening shall be capable of a swivelling action
I proceed as follows :-
In place of the tubular pendant already described, I provide an outer tubular
pendant, or what perhaps may be more strictly termed a cylinder, in which are the
holes in its sides, as already explained through which the ends of the bows pass,
and which are secured upon the inside by the slotted expanding cylinder or band
as before.
Upon the external of the (inner or) pendant proper, I make a circular groove,
equal in width and depth, to the diameter and thickness of the collar projecting within
the expanding cylinder or band, and having further, two flats, or if preferred,
depressed surfaces, diametric to each other, in the said groove. Thus, when the two
ends of the bows are first passed into the outer pendant cylinder, and sprung or held
open while the pendant proper is passed into its place (that is, until the collars upon
the bow, shall close into the circular groove) then the expanding slotted cylinder is
passed between the outer and inner pendants, on to the neck of the grooves upon
the bow, and secured as before explained. Thus the bow is firmly attached to the
inner pendant and also capable of a swivel or rotating action, by reason of the end
collars of the bow, taking into the circular groove upon the said inner pendant.
By reason of the closing elasticity of the bow, when the collars come opposite to, or
upon, the flats or depressed portion of the surface of the circular groove, they will
have a strong tendency to remain there, thus forming its normal position; which
would be such, that the said bow would be flatwise with the watch.
In the case however of any attempt to wrench the watch from the pendant, as is
usually the case with thieves, the said bow would rotate, and thus frustrate their
designs.
By these means no pins or screws are necessary to connect the parts together, or
to retain the expanding band in the pendant, as is usual, nor does there require any
cutting away of the pendant beyond the piercing of the side circular holes, or
the circular groove spoken of, while it affords increased safety and protection from
thieves.

page_text: Improvements in Securing Bows or Rings to Tubular Attachments
for Watches and other Analogous Purposes.
I LOUIS PLATNAUER, of Saint Pauls Square, Birmingham, in the county of Warwick
Watch Manufacturer 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 relates to improvements in connection with the securing of the bows
or rings, primarily of keyless and other watches to their pendants, but which may also
be used for securing the ends of other bows, or other such ends, capable of such treat-
ment, to effect their fastening under similar circumstances, and has for its object, first
to provide an improved arrangement of parts constituting means for securing the bows
or ends to their pendant or other part, and further to provide, that such fastening
shall be capable if desired, of a swivel action upon the article to which it is
secured.
I will first describe that part of my invention which relates particularly to securing
the ends of the bows, that is, apart from the swivel action, in which the said bow has
at its two ends, a circular neck or groove behind a collar, which shall pass through
circular openings in the side of the pendant, and be there secured, by means of an
expanding metallic cylinder or band, having two bayonet-joint shaped slots, engaging
each with the neck at the end of the aforesaid bow; the width of the slots being equal
to the diameter of the bottom of the neck or groove.
Thus, having passed the ends of the bow through the openings in the side of the
tubular pendant, until the circular groove stands forward, within the said tubular
pendant; the expanding band is then passed down within the said pendant; the
vertical portions of the slots first engaging with the grooves or necks, until the said
necks of the bow reach the horizontal portion of the slot, when the band would be
turned round a short distance, the said neck thereby passing along, and resting in the
said horizontal portion of the slot: It will thus be obvious that the bow cannot
possibly be withdrawn, until the band has been again turned backward intentionally.
In order to further provide that this fastening shall be capable of a swivelling action
I proceed as follows:-
In place of the tubular pendant already described, I provide an outer tubular
pendant, or what perhaps may be more strictly termed a cylinder, in which are the
holes in its sides, as already explained through which the ends of the bows pass,
and which are secured upon the inside by the slotted expanding cylinder or band as
before.
Upon the external of the (inner or) pendant proper, I make a circular groove, equal
in width and depth, to the diameter and thickness of the collar projecting within tho

page_text: expanding cylinder or band, and having further, two flats, or if preferred, depressed
surfaces, diametric to each other, in the said groove. Thus, when the two ends of the
bows are first passed into the outer pendant cylinder, and sprung or held open while
the pendant proper is passed into its place (that is, until the collars upon the bow,
shall close into the circular groove) then the expanding slotted cylinder is passed
between the outer and inner pendants, on to the neck of the grooves upon the bow,
and secured as before explained. Thus the bow is firmly attached to the inner
pendant and also capable of a swivel or rotating action by reason of the end collars
of the bow, taking into the circular groove upon the said inner pendant.
By reason of the closing elasticity of the bow, when the collars come opposite to, or
upon, the flats or depressed portion of the surface of the circular groove, they will
have a strong tendency to remain there, thus forming its normal position; which would
bo such, that the said bow would be flatwise with the watch.
In the case however of any attempt to wrench the watch from the pendant as is
usually the case with thieves, the said bow would rotate, and thus frustrate their
designs.
I will now proceed to more particularly describe this my invention and how it may
be carried into effect, having reference to the accompanying illustrative sheet of
drawings, upon which are figures and letters of reference, similar letters roferring
throughout the several views to the same thing or part.
Fig. 1, represents in elevation and section, the tubular pendant of a keyless
watch.
Fig. 2, shows in elevation and section the expanding cylinder for securing the ends
of the bow inside the pendant.
Fig. 3, is a view of the bow, showing the ends prepared for the fastening.
Fig. 4, illustrates the locked position of the bow end in the bayonet fastening
shaped slot.
Fig. 5, shows in sectional elevation these parts put together, and secured by the
expanding cylinder.
Fig. 6, shows in section and elevation an outer pendant or cylinder, used when it
is desired that the parts shall be so secured as to be capable of the swivel action.
Fig. 7, shows in section and elevation the pendant as arranged for the fastening
which is to have a swivel action.
Fig. 8, is a sectional plan of Fig. 7, upon line A B.
Fig. 9, shows in sectional elevation the said fastening, capable of a swivel action.
Fig. 10, shows somewhat the external form the arrangement would take.
to
a, is the bow whose ends are grooved or necked at b, which thereby forms the
collar c. d, is the pendant of the watch to which it is intended that the said bow shall
be secured, having holes e, e, pierced through its sides, permitting the collars
pass therethrough into its interior, its tubular form affording facilities for the winding
or other mechanism. f, is a metallic expanding cylinder preferably of steel, and
provided with a bayonot-joint shaped slot g, upon each side, which is equal in width
to the diameter of the neck or groove b, of the bow. From this, and upon reference
to Fig. 5, it will be seen that the ends of the bows are first passed through the
holes until the neck or groove stands just within the tubular form of the said
pendant d, then the expanding cylinder f, is passed down within the tube, the necks b,
of the bows taking into the slot g, until the top or horizontal portion of the said slot,
has reached them, when the said cylinder, is turned around a little, the necks sliding
or passing into the horizontal portion of the slot, as seen in Fig. 4. Thus until the
expanding cylinder has been removed, it is impossible to withdraw the bow from the
pendant.
Again, it is further provided that this fastening may be so carried out as to enable
it to swivel upon the pendant. In order to do this, instead of piercing holes in the
pendant proper h, I make a groove i, (see Fig. 7) of a suitable size to receive the
inner ends or collars c, of the bow. I further provide an outer pendant or cylinder j,
in which the two holes e, e, are made. It will be now clearly seen upon reference to
Fig. 9, that upon first passing the pendant or cylinder i, upon the exterior of the

page_text: inner or pendant proper h, until the holes e, e, come opposite to the groove i, then
passing the ends of the bow through the said holes into the groove, the expanding
cylinder, is passed down as before engaging with the neck or groove as before
described.
Thus the bow is capable not only of a pivot motion horizontally upon the necks b,
but also a vertical rotary motion, due to the collars e, working in the groove i.
It is well known that thieves, when stealing a watch from a person in order to
readily disengage it from the watch chain, wrench or twist it off at the bow.
In this my invention however the said bow when so treated would turn round in
the groove and thus foil his purpose.
The normal position of the bow however would be such as is ordinarily, as seen in
Fig. 10.
Hence upon opposite sides of the groove i, a flat, or slight depression is made as
seen at k, Fig. 8, so that when the collars c, come opposite thereto there shall be
some tendency for them to remain there.
The winder 7, (see Fig. 10) or other parts of the mechanism would be applied and
used as ordinarily.
Although I have described this my invention as being particularly useful as
pertaining to watches, yet it will be manifest that it will be also applicable to secure
the ends of other bows, or other such ends as are capable of similar treatment.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that
what I claim is :-
1st. Securing the ends of watch or other bows within a tubular pendant, by
means of the combination with a tubular pendant d, having perforations e, e, and
the ends of the bow a, having collars c, of the expanding cylinder f, having the
bayonet joint shaped slot y, substantially as and for the purposes specified.
2nd. The combination with the collars c, the outer pendant or cylinder j, and the
expanding cylinder f, of the groove i, in the inner pendant h, substantially as shown
and for the purpose specified.
3rd. The combination with the groove i, in the pendant h, of the flats or
depressions k, substantially as shown and for the purpose specified.
