I, ISAAC LAZARUS, of Birmingham, in the County of Warwick, Jeweller
and Factor, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN FASTENINGS FOR BROOCHES AND OTHER ARTICLES OF JEWELLERY, WHICH
SAID IMPROVEMENTS ARE ALSO APPLICABLE TO FASTENINGS FOR FASTENING ARTICLES
OF DRESS AND FOR OTHER LIKE PURPOSES," to be follows:-
My Invention consists of the improvements hereinafter described in fasten-
ings for brooches and other articles of jewellery and in dress fastenings and
other like fastenings.
My said Invention is however specially applicable to brooches and I will
describe it as applied to a brooch.. At the back of the brooch I fix a tube,
which tube passes from end to end of the said brooch. In one half of this
tube a rod slides, the end of the said rod being made into a knob or head
which is situated outside the tube. The knob or head described carries a pin
the pointed part of which is bent inwards and is situated nearly parallel with
the tube. Within the tube and around the rod is a coiled or helical spring
one end of which spring bears against a collar on the bottom of the rod and
the other end against the top of the tube. When the rod carrying the pin
is drawn fram the tube by grasping the knob or head the before-mentioned
spring is compressed. The knob or head being loosed from the fingers the
rod is drawn into the tube by the spring and the end of the tube closed by the
knob or head. The opposite end of the tube to that at which the elastic pin

page_text: is situated is furnished with a fixed pin of a similar form to the elastic one, the
points of the said pins being turned towards each other. In attaching a
brooch provided with my improvements to a dress, the fixed pin is first inserted
into the said dress, the elastic pin is then moved from the end of the brooch
by drawing the rod from the tube; on releasing the said rod the pin con-
nected to it enters the dress and securely fastens the brooch thereto. To
unfasten the brooch the rod is drawn from the tube and the pin thereby with-
drawn from the dress, the opposite pin can then be removed and the brooch
separated from the dress. Instead of employing an elastic pin and a fixed pin
at opposite ends of the brooch as described both pins may be made elastic.
In this case one or both of the pins may be drawn out of the tube in fastening
the brooch to or separating it from the dress. Instead of a single pin at each
end of the brooch a double pin may be used. In addition to the great
securety obtained in the fastening of the brooch or article by the use of my
Invention the position of the hooked pins prevents them from injuring the
person wearing the brooch or article, or the children that may be nursed by
the person wearing the brooch or article. I do not limit myself to the use of
any particular kind of spring for drawing the rod carrying the pin into the
tube, but I prefer to employ a coiled or helical spring of metal.
In applying my Invention to the fastenings of other articles of jewellery
and to dress and other fastenings, such modifications of the arrangements
described are employed as are necessary to fit them to the particular articles
with which they are used, which modifications I do not think it necessary
here to describe.
