PROVISIONAL SPECIFICATION.
Improvements relating to Studs, Solitaires, and the like.
I, CHARLES HENRY OWEN, of the Firm of Henry Owen and Sons, of 28,
Augusta Street, in the City of Birmingham, Manufacturers, do hereby declare
the nature of this invention to be as follows:-
This invention consists of improvements relating to studs, solitaires, and like
fasteners having a shank which is free to revolve or rotate within the pearl or
other back piece, my object being to provide a more effectual and durable con-
nection between the inner end of the shank and the said back piece.
In the application of my invention to the manufacture of a stud or solitaire
having a revolving or rotatable shank, I insert in the central aperture through
the pearl or other back piece a metallic eyelet having one end flanged to form
an abutment preventing its being drawn right through to the front side of the
back piece. The opposite end of the eyelet, which projects through the back
piece, is pressed over on to the adjacent portion of the front face of the back
piece.
The eyelet has such an internal diameter as to permit the shank to fit loosely
within it. The inner end of the shank, after it has been passed through the
eyelet, is Hanged over in the ordinary manner to prevent detachment.
The back or rear side of the aperture through the pearl or other back piece
of the stud, is suitably enlarged to receive the metallic closing cap, and the
shoulder formed in the material, between the larger and smaller ends of the
aperture, is made of such a rounded section that as the closing cap is forced into
the back piece with its open end foremost, the said end is curled or forced in-
wardly and caused to embrace the flanged end of the eyelet hereinbefore re-
ferred to.
By my invention I am enabled to readily make an effective and durable con-
nection between the shank of a stud or the like and its back piece or equivalent
part, without damaging the pearl or other material from which such part is
formed.

COMPLETE SPECIFICATION.
Improvements relating to Studs, Solitaires, and the like.
I, CHARLES HENRY OWEN, of the Firm of Henry Owen & Sons, of Caroline
Street. (formerly of 28, Augusta Street), in the City of Birmingham, Manu-
facturers, 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 consists of improvements relating to studs, solitaires, and the
like fasteners having a shank which is free to revolve or rotate within the
pearl or other back piece, my object being to provide a more effectual and durable
connection between the inner end of the shank and the said back piece.

page_text: On the accompanying sheet of explanatory drawings to be hereinafter re-
ferred to.
Figure 1 is an elevation of a complete stud or solitaire as constructed in accord-
ance with my invention.
Figure 2 is a plan of the stud showing the rear end of the back piece.
Figure 3 is a sectional elevation of the back piece alone, and Figure 4 a
similar view of the back piece with the eyelet in position therein.
Figure 5 is an elevation (wth parts in section) showing the shank within the
eyelet of the back piece, and Figure 6 a similar view but showing also the
closing cap in position.
Figure
is a sectional elevation and Figure 8 a plan of the eyelet (before it
is fixed in position in the back piece), whilst Figures 9 and 10 are similar views
of the closing cap.
The same reference letters in the different views indicate the same parts.
In the application of my invention to the manufacture of a stud or solitaire
having a revolving or rotatable shank as A, I insert in the central aperture
through the pearl or other back piece B a metallic eyelet Chaving one end
flanged to form an abutment preventing its being drawn right through to the
front side of the back piece. The opposite end of the eyelet, which projects
through the back piece, is pressed over on to the adjacent portion of the front
face of the back piece.
The eyelet has such an internal diameter as will permit the shank to fit
freely within it. The inner end of the shank, after it has been passed through
the eyelet is flanged over (as shown at Figure 5), in the ordinary manner, to
prevent detachment.
The back or rear side of the aperture through the pearl or other back piece
of the stud, is suitably enlarged to receive the metallic closing cap or centre D),
and the shoulder formed in the material, between the larger and smaller ends
of the aperture, is made of such a rounded section that as the closing cap is
forced into the back piece with its open end foremost, the said end is curled, or
flanged, or rolled inwardly and caused to embrace the flanged end of the eye-
let C, as shown at Figure 6.
By my invention I am enabled to readily make an effective and durable con-
nection between the shank of a stud or the like and its back piece or or equivalent
part, without damaging the pearl or other material from which such part is
formed.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what
I claim is:
1. In studs, solitaires, and the like, the attachment of the closing cap or
centre with the eyelet of the back piece, substantially as described.
2. In studs, solitaires, and the like, the formation of the aperture through the
pearl or other back piece in such a manner as to cause it to curl or roll in the
open end of the metallic closing cap when the latter is forced therein, sub-
stantially as and for the purpose described and as illustrated.
3. A stud, solitaire, or the like, having a shank which whilst free to revolve
or rotate within the pearl or other back piece is effectually connected thereto
substantially in the manner described and as illustrated.
