Year: 1878

page_text: LETTERS PATENT to Joseph Clark, of Liverpool, in the County of Lancaster,
for the Invention of," AN IMPROVED SAFETY FASTENING FOR STUDS, BUTTONS,
BROOCHES. AND ANALOGOUS ARTICLES."
PROVISIONAL SPECIFICATION left by the said Joseph Clark at the Office
of the Commissioners of Patents on the 11th September 1878.
JOSEPH CLARK, of Liverpool, in the County of Lancaster. "AN IMPROVED
SAFETY FASTENING FOR STUDS, BUTTONS, BROOCHES, AND ANALOGOUS ARTICLES,"
This Invention relates to an improved safety fastening for securing studs, for
example, shirt studs, buttons, brooches, and analogous articles, and consists in
formning on the back of the stud, button, brooch, or other article a shank or pro-
jection, provided at its end with a stop or catch.
To the shank or projection there is hinged a bar or lever, to which bar or lever
is hinged a second bar or lever formed of a spring loop.
The second bar or lever is arranged that it will fold down and spring over the
projection on the shank and form with the first bar or lever a T on the end of the
shank.
In operation the levers or bars are sprung out from the end of the shank, so as
to easily pass through an eyelet or button hole, after which the levers are folded
over, and the outside lever sprung over the end of the shank and the stud is
secured.
For studs, buttons, and like articles, the shank and levers may be made flat.
For brooches, the levers and shank may be made round, with a pointed end if
wished.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Joseph Clark in the Great Seal Patent Office on the 11th March
1879.

example, shirt studs, buttons, brooches, and analogous articles, and consists in
forming on the back of the stud, button, brooch, or other article a shank or pro-
jection provided at its end with a stop or catch.
To the shank or projection there is hinged a bar or lover, to which bar or lever
is hinged a second bar or lever formed of a spring loop.
The second bar or lever is arranged that it will fold down and spring over the
projection on the shank, and form with the first bar or lever a T on the end of the
shank.
The before-going being the nature of my Invention I will now proceed to describe
in detail how the same may be carried out in practical effect, and for that purpose I
have hereunto attached a Sheet of Drawings illustrative thereof, marked with
figures and letters of reference corresponding with those in the following explanation,
the same letters of reference being used to denote like or corresponding parts
throughout the various views of the Drawings.
Figure 1 is an elevation of a shirt stud with a fastening constructed according
to my Invention.
Figure 2 is an enlarged view of Figuro 1 with the fastening shown closed.
Figure 3 is an elevation of an enlarged view of a fastening and stud, constructed
according to my Invention, shown open and partly in section.
Figure 4 is a side view of Figure 3.
Figure 5 is a plan viewed from the under side of Figure 2.
Upon roference to the Drawings it will be seen that a safety fastening constructed
according to my Invention consists in providing the button or main portion of the
stud, button, brooch, or other article A with a shank or projection B provided at
its end with a stock or catch C.
To the shank B there is hinged at D a bar or lever E, to which is hinged at Fa
second bar or lever H formed of a spring loop.
The spring loop bar H is arranged so that it will fold down and spring over the
projection, being the stop or catch C on the shank B in position, as shown at
Figures 2 and 5.
In operation the fastening is opened out, as shown at Figures 3 and 4, so as to
easily pass through an eyelet or button hole, or eyelets or button holes, after which
the fastening is folded up as shown at Figure 2, and is thereby secured.
For studs, buttons, and like articles, the fastening may be made exactly as shown
in the Drawings.
For brooches, the spring loop bar H may be provided with a pointed end if
desired, as shown at J in dotted lines.
Having now described and ascertained the nature, object, and purposes of my
Invention, and shown how the same may be carried out into practical effect, what
I claim as my Invention and secured to me by Letters Patent as aforesaid is, the con-
struction and arrangement of a fastening for studs, buttons, brooches, and analogous
articles, consisting of the combination of a hinged bar or lever, such as E, and the
spring loop, such as H, with the shank B, as hercin-before described and shown in
the accompanying Drawings, or any modification thereof.
In witness whereof, I, the said Joseph Clark, have hereunto set my hand
and seal, this Fourth day of March, in the year of our Lord One thousand
eight hundred and seventy-nine.
