Improvements in Studs for Shirts, Collars, Cuffs, and the Like.
I, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex do hereby declare the nature of
this invention to be as follows:-
This invention relates to a stud for cuffs, collars, shirt fronts, and the like, which
presents over the studs heretofore employed the advantage that it can be very readily
put in place and removed without risk of deteriorating the stud holes.
The principle upon which the said invention is based consists essentially in providing
upon the shaft of the stud a helix which is secured thereon in any suitable manner,
and the radius of which gradually diminishes in proportion as the helix approaches
the body of the stud.
The said helix thus forms a screw thread, between the convolutions of which are
held the two parts of the fabric which the stud is designed to connect.
It is sufficient to turn the stud in one or the other direction in order to put it in
place or remove it from the stud hole, whilst in the case of the studs as heretofore
made with a helix, as the latter consists only of one convolution and has a constant
radius, the fabric is liable to be torn by the lower point of the helix when the stud
is removed.

Improvements in Studs for Shirts, Collars, Cuffs, and the Like.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings in the County of Middlesex, 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 statement :—
This invention relates to studs for cuffs, collars, shirt-fronts and the like, which studs
have the advantage over studs hitherto used that they can be inserted into or removed
from the button hole without unnecessary loss of time, and without injury to the edges
of the hole.
The accompanying drawing shows a stud constructed according to the present
invention as well as the principle upon which the invention is based.
The said stud consists substantially of a spiral wound around the shank of the stud
and soldered to it, the radius of the said spiral gradually decreasing as it approaches
the head of the stud, where it runs off to nothing. The spiral thus forms a screw
between the threads of which the two parts of the stuff or garment are held which the
stud is to fasten together. Thus the stud may be inserted into, or removed from the
hole by simply being turned in one or the other direction.
In spiral studs hitherto used, on the contrary, the spiral consisting of one con-
volution only and having the same radius throughout, there is considerable risk
of injuring the stuff by the lower end of the spiral when removing the stud.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is:
The improved stud with a spiral foot; the spiral being wound around the shank
of the stud and soldered to the same the radius of the said spiral gradually diminishing
towards the head of the stud, where it falls away to nothing substantially as
described.
