A SPRING FASTENING FOR SOLITAIRES STUDS &C.
Year: 1884

page_text: ARTHUR JAMES PETTIT Back 43 Whitmore Street, Birmingham, Jeweller, do
hereby declare the nature of my invention for A SPRING FASTENING FOR
SOLITAIRES STUDS &C. to be as follows:-
Improvements in Fastenings of Studs, Solitaires, Buttons &c whereby the same
may be easily and readily unfastened by merely turning and pressing the outer
face or front of such solitaire, stud or button. I prefer to employ a spring so
attached to the bottom or back of Solitaire &c, as to act upon a projecting pin
attached to the front of the Solitaire &c, and in order to secure this pin or plug
from unfastening or turning in its hollow case, I attach a guide pin to the
projecting plug or pin which guide pin works in a suitably formed slot or groove
in the hollow case of the back of the solitaire, stud or button.
The bottom part of Solitaire Stud or Button has a projecting tube, in the bottom
of which is placed a coiled spring. This tube also has cut upon it a groove or slot
of a form to allow of a vertical motion for a short distance and then a horizontal
motion or inclined motion for a short distance which leads into a recess or step.
The upper or front part of solitaire stud or button has a pin projecting from it
which works into the tube upon the back of stud &c, pressing upon the spring
placed in the bottom of the tube.
Upon this projecting pin is a small guide pin to fit the groove in the tube.
To prevent the tube from being burst open by the pin in the groove a sleavé
may be passed over the tube, or I place a ring around the mouth of the tube.
Thus by pressing the front of the Solitaire stud or button into the tube, so that
the guide pin will slide down the vertical slot until it reaches the bottom, and
then causing it to travel the horizontal or inclined groove; the spring is then free
to force it into the little step or recess and thereby prevent any unfastening or
working loose.

ARTHUR JAMES PETTIT, Back 43 Whitmore Street, Hockley, Birmingham, in the
County of Warwick, Jeweller do hereby declare the nature of my invention for
AN IMPROVED SPRING FASTENING FOR SOLITAIRES, STUDS AND BUTTONS, and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
My Invention consists in the construction of Improvements in Fastenings of
Studs, Solitaires and Buttons whereby the same may be easily and readily
unfastened by merely pressing and turning the outer face or front of such solitaire,
stud or button. I prefer to employ a spring so attached to the bottom or back of
solitaire, stud or button, as to act upon a projecting pin attached to the front of the
Solitaire stud or button, and in order to secure this pin or plug from unfastening
or turning in its hollow case I attach a guide pin to the projecting plug or pin,
which guide pin works in a suitably formed slot or groove in the hollow case of
the back of the solitaire, stud or button. The bottom part of the Solitaire Stud or
Button has a projecting tube, in the bottom of which is placed a coiled spring.
This tube also has cut upon it a groove or slot of a form to allow of a vertical
motion for a short distance, and then a horizontal motion or inclined motion for a
short distance, which leads into a recess or step.
The upper or front part of solitaire, stud or button has a pin projecting from it,
which works into the tube upon the back of the solitaire stud or button, pressing
upon the spring placed in the bottom of the tube. Upon this projecting pin is a
small guide pin, to fit the groove in the tube. To prevent the tube from being
burst open by the pin in the groove, a sleave may be passed over the tube, or
I place a ring around the mouth of the tube.
Thus, by pressing the front of the solitaire stud or button into the tube, so that
the guide pin will slide down the vertical slot until it reaches the bottom, and then
causing it to travel the horizontal or inclined groove; the spring is then free to
force it into the little step or recess and thereby prevent any unfastening or
working loose.
In carrying my invention into effect in the simplest way I construct a Solitaire
as follows, and as set forth in the accompanying Drawing.
Having explained the nature of my Invention I will proceed to describe with
reference to the accompanying Drawing the manner in which the same is to be
performed.
Figure 1 represents an elevation or external view of a solitaire, and Figure 2 a
vertical section through a solitaire constructed according to my invention.
A is the upper portion, having connected thereto a stem or plug B, working into
a hollow cylindrical tube C, which tube is connected or rigidly secured to the lower
portion D, of the Solitaire. The plug B, has attached to it a pin E, which may be
either formed out of the metal of the plug B itself or may be rigidly secured to the
same in such a manner that the pin E, shall fit into the vertical slot F, cut down

page_text: each side of the tube C. At the bottom end of each slot F, is a short horizontal
slot or groove G. leading into a short vertical slot or groove H, as shown in
Figure 5 and Figure 7.
The plug B is caused to come into contact with a spiral spring I, shown in
Figure 2, the same being secured to the bottom part D, of the solitaire.
The tube C, having the slots or grooves F, G, H, cut in its surface is protected
by an outer casing or sleave J, also secured to the bottom part D of the solitaire ;
the mouth of the tube being further stiffened by a bulb or ring as indicated in
Figure 2 and Figure 5.
Thus when the top portion A is caused to enter the bottom portion D, the plug B
presses against the spiral spring I, and by a slight turn being given to the upper
part D when the pin E has reached the lowest position in the vertical slots F, so as
to cause the pin E to traverse the short horizontal slots G; the pin E is forced
upwards by the spring and thereby securely held or locked in the vertical
slots H; in this manner the upper and lower parts of the solitaire are connected
together.
To disconnect the same it is neccessary to push the top portion A, so that the
pin E shall move down the vertical slot H, then slightly turn the same top portion
until the end of the horizontal alot G is reached, and when in this position the top
portion can be withdrawn from the bottom portion, the spiral spring I assisting to
force them apart.
The application of my invention to studs and buttons other than solitaires,
differs in no essential respect from its application to solitaires as herein before
explained.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
1st The peculiar form of the slots cut in the tube of the lower portion of the
Solitaire, stud or button, for the purpose of receiving the projecting pin attached to
the upper portion of the Solitaire stud or button; substantially as hereinbefore
described and as illustrated in the accompanying Drawing,
Dated this Seventh day of May 1885
