PROVISIONAL SPECIFICATION.
An Improved Means for Affixing Bows to Keyless Watches.
SAMUEL THOMAS RUDGE, Market Place, Dursley, in the county of Gloucester,
Watchmaker do hereby declare the nature of this invention to be as follows:―
I have the pendant formed as a cylinder with a projecting shoulder near the bottom
which has a V groove in its upper surface. Around this pendant I place a ring band
with tapered edges, to this ring the bow is screwed, the screws being inserted from
the inside of the ring into the bow, or through the bow into the ring. One edge of
this ring fits into the above V grooved shoulder thereby gaining strength. The upper
part of the pendant has a screw thread round it, and on this a tapered cylinder is
screwed the tapered part of which holds and covers the upper edge of the ring band;
this arrangement allowing the ring band and bow to revolve when an attempt is made
to twist the bow on the pendant. An indentation is made in the upper and lower
parts of the pendant, a prominence in the screwed cylinder fits into the upper indenta-
tion, and a prominence in the ring band fits into the lower indentation on the pendant
thus giving the bow and its ring a certain amount of rigidity.

COMPLETE
SPECIFICATION.
An Improved Means for Affixing Bows to Keyless Watches.
SAMUEL THOMAS RUDGE, Market Place, Dursley Gloucestershire Watchmaker, 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 state-
ment:-
This invention is to fix the bow or ring more firmly to the watch case and to allow
the bow to revolve when any attempt is made to separate it from the case by twisting
thus relieving the strain on the screws. To carry this object out and that it may be
fully understood I append one sheet of drawing.
The pendant (A) is a tube with a projecting shoulder near or towards the bottom
which has an angular V groove on its upper surface. Round this pendant the ring
band (B) is placed with tapered edges to which the bow E is pivoted by two screws (DD)
being inserted opposite each other from the inside of the ring (B) into the ends of the
bow, or from the outside through the bow into the ring (B). The lower tapered edge
of the ring (B) when in its place fits into the grooved shoulder on the pendant (A).
The upper part of this pendant has a screwed thread round it and on this a collar (C)
is screwed, its lower edge being tapered so that it fits on & covers the upper edge of
the ring (B) or this collar may be fixed on by a small screw or screws passing
through the pendant (A).
This arrangement allows the bow (E) and the swivel ring (B) to revolve round the
pendant (A) when an attempt is made to twist the bow off the pendant. An indenta-
tion or slot (F fig. 2) is made in the upper part of the pendant (A) (when screws are
not used) to receive the projection (G) (fig. 1) on the upper part of the collar (C).
A slot or indentation (H fig. 4) is made on the lower part of the swivel ring (B)
which receives the projection (I fig. 2) which is made on the V groove on the pendant.
With the above indentations & slots (G F H I) the ring B will have sufficient rigidity
to maintain its desired position on the pendant during ordinary use.

page_text: Having now particularly described & 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
1st. Ring B with its conical edges & the methods of screwing the bow thereto.
2nd. The collar or screwed cylinder (C).
3rd. The V groove on the pendant to receive lower edge of swivel ring B.
4th. The indentations F & H fig. 2 & 4 & the projections G & I fig. 3 & 4 'fitting
into them.
Dated this Second day of April 1890.
