Complete Specification Left, 14th Sept., 1891-Accepted, 31st Oct., 1891
PROVISIONAL SPECIFICATION.
An Improved Fastening for Scarf Slides.
We CHARLES BAYLEY BRAGG, Jeweller, of 12 Northampton Street, Bir-
mingham, and, TномAS JAMES FLETCHER, Jeweller, of 133 Leonard Road,
Handsworth, Birmingham do hereby declare the nature of this invention to be as
follows:-
Our invention of an improved fastening for scarf slides, consists of a combined
spring and catch or click, attachment, which act together in such a manner, that
they hold the slide securely locked, when closed. This locking is effected by
forming a notch or projection on both the spring and the catch, respectively, with
the following result.
When the slide is open and required to be closed, the notch on the catch is caused
to press against the notch on the spring, during the action of closing, until it
arrives at the spring projection, when the spring, which has been raised, or thrown
out of position, by the action or movement of the catch, falls back, and holds
the catch securely behind its projection, until the slide is required to be again
opened.
And inasmuch as the Patent claimed consists mainly in the arrangement and form
of the spring and the catch, the notch on which is only incidental. The whole
mechanism can, if desired, be so constructed without the notch, before referred to,
and depend simply on the extra strength or force of the spring to keep the slide
closed.

COMPLETE SPECIFICATION.
An Improved Fastening for Scarf Slides.
We CHARLES BAYLEY BRAGG Jeweller, of 12, Northampton Street, Bir-
mingham, and THOMAS JAMES FLETCHER, Jeweller, of 133 Leonard Road,
Handsworth, Birmingham, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
Our invention of an improved fastening for scarf slides, consists of a combined
spring and catch or click attachment, which act together in such a manner that they
hold the slide securely locked when closed. This locking is effected, by forming a
notch or projection on both the spring and the catch respectively, with the following
result.
When the slide is open and required to be closed, the notch on the catch is caused
to press against the notch on the spring, during the action of closing, until it arrives
at the spring projection, when the spring which has been raised or thrown out of
position by the action or movement of the catch, falls back and holds the catch
securely behind its projection, until the slide is required to be again opened.
And inasmuch as the patent claimed consists mainly in the arrangement and form
of the spring and the catch, the notch on which is only incidental. The whole
mechanism, can, if desired, be so constructed without the notch, before referred to,
and depend simply on the extra strength or force of the spring to keep the slide
closed.
The spring in the ordinary slide acts on a projection, formed at the jointed end of

page_text: the slide, and keeps the slide closed by pressure alone, and is always pressing against
the joint, whether open or closed. Whereas in our invention, the joint is perfectly
free from any action of the spring, as the latter only comes into use, during and
after the action of closing.
The nature of our improved fastening is best shown by reference to the accom-
panying drawings.
Fig. 1., is a side elevation of the slide complete, slightly open.
Figs. 2 and 3, are sectional plans, closed and open.
A, represents the frame or form of the slide; B, the spring with its projection b;
C, shows the catch and its projection cd, Fig. 1., shows the spring, part of the
edge being removed in the drawing for this purpose.
C
The spring B, may be made of any suitable strength, and the projections and c,
of any depth, and at suitable angles with each other, and will vary according to the
desired force required to overcome the resistance of the spring.
The spring is fixed in position by a screw formed on the end of the peg e, which 1
passes through the bar; or by any other suitable means.
The fastening is made either in gold, silver, or metal.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
clain is :-
The arrangement and form of the spring and catch, constructed substantially as
above described, and for the purposes stated, in this our Complete Specification.
Dated this 11th day of September 1891.
