PROVISIONAL SPECIFICATION.
An Improved Shirt or Collar Stud.
1 ANDREAS PETER LUNDBERG Manufacturer 18 Regina Road Tollington Park
London N. do hereby declare the nature of this invention to be as follows:-
-
These articles as usually constructed consist of a front button or head and a back
button connected by an inflexible stem. The most general method of construction, is
to make the three parts quite rigid either by turning them out of one piece, or of
separate pieces screwed together, in either case allowing of no movement whatever
between the front and back of the stud. This system of construction causes them to
be very inconvenient to many wearers, and attempts have been made to overcome this
defect by constructing the front button and the connecting stem in one piece, and
attaching it by means of some kind of ball and socket joint to the back button, this
construction allowing of some side and up and down movement of the front button
and the stem, but this only partially overcomes the defect.
The object of my invention is a new method of construction of these articles, and
consists of uniting the front and back of the stud by means of a spiral metal spring
preferably of hard steel, the spring being attached at one end to the front and the
other end to the back part of the stud.
The spring may be attached to the front, and back part of the stud in many ways,
thus the front and back may be made of metal and the spring soldered to the front
and back part of the stud, or the metal may be pressed round the spring at each end,
or each end may have a short screw attached and screwed into the spiral, or the ends
of the spring may be formed into loops and booked into suitably arranged holes, or by
any other well known mechanical means of attachment.
But the plan I prefer is to form the front & back of the stud of any material capablo
of having a female screw cut in the centre, and simply screw in the spring as a male
screw. As a further safeguard against the spring pulling out it may have a screw
screwed into the inside of the spring from the back, and if necessary from the front
also; after it is itself screwed into the front and back buttons of the stud, thus forcing
open the spring and causing it to fit the female screw in the front and back button of
the stud, very tightly, and preventing all possibility of the parts coming asunder.

manner the same is to be performed, to be particularly described and ascertained in
and by the following statement:-

The object of my invention, is a new method of construction of these articles, and
consists of uniting the front & back of the stud, by means of a spiral metal spring
(preferably of hard steel), the spring being attached at one end to the front, and the
other end to the back part of the stud.
The spring may be attached to the front and back part of the stud in many ways,
thus the front and back may be made of metal, and the spring soldered to the front &
back parts of the stud; or the metal may be pressed round the spring at each end; or
each end may have a short screw attached and screwed into the spiral; or the ends of
the spring may be formed into loops and hooked into suitably arranged holes; or by
any other well known mechanical means of attachment.
But the plan I prefer, is to form the front and back of the stud of any material
capable of having a female screw cut into the centre, and simply screw in the spring,
as a male screw. As a further safeguard against the spring pulling out, it may have
a screw screwed into the inside of the spring from the back, and, if necessary, from
the front also, after it is itself screwed into the front and back button of the stud;
thus forcing open the spring, and causing it to fit the female screw in the front and
back buttons of the stud very tightly, and preventing all possibility of the parts
coming asunder.
Inside the spring stem of the stud, I place a flexible cord, composed of a number of
thin metal wires, & by fixing each end of this cord to each end of the spring stem, it
will prevent any undue stretching of the spring-stem, which otherwise might occur.
The drawing herewith attaclied, represents an enlarged section of a stud, as
described above. A is the back button of the stud. B is the front button of the
stud. is the spiral-flexible stem, uniting the front and back button. D is the
flexible cord composed of many thin metal wires.
Having now particularly described, and 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
The flexible connection between the front and back parts of the stud, consisting of
a spiral of metal wire, of any convenient size or section.
