PROVISIONAL SPECIFICATION.
Improvements in Studs, Pedigree Plates for Sheep, Solitaires,
Sleevelinks, and the like.
I, SAMUEL LEIGHTON, of Newmarket, Lancaster, in the County of Lancaster,
Jeweller, do hereby declare the nature of this invention to be as follows:-
:-
This invention has for its object a stud which shall not easily fall out, and which
can be opened and closed without difficulty.
I form the base of the stud in the ordinary manner of a preferably round plate
supporting a pillar in the centre. This pillar has a small terminal Hange, and a
second circular flange immediately above it. The head consists of a box formed of
the ornamental head for the upper portion, and a flat plate for the lower portion.
This flat plate has two round holes in it, one close to the side large enough to take
in the entire head of the pillar, and the other in the centre just large enough to
take in the smaller of the two discs or flanges on the pillar. These two holes are
united by a slot just large enough for the pillar itself below the two flanges to slide
in. Immediately below this plate is a second loose plate, and below this a spring
tending to press this loose plate up against the stationary bottom plate of the head.
On the side of the stud next to the large hole is a knob or other indicator to show
where the large hole is.
The mode of using it is as follows:-The lower portion of the stud being placed
in the cuff, and the cuff buttoned on to it, the head is placed with the large hole
immediately over the head of the pillar and pressed down. The pillar enters the
head. The head is now pushed on towards the centre, the stem of the pillar sliding
in the slot. The moment the pillar reaches the centre pressure is removed and the
pressure of the spring causes the smaller disc to enter the hole thus locking the
stud in position. To undo it one has merely to press the stuid, and then move
the head in the contrary direction to the lump or indication on the side of the stud
head. By this means the slot slides over the pillar and the pillar comes opposite
the larger hole. The head can now be removed from the stud.
It is obvious that although I have described the invention only for round studs,
it would be more applicable for oval or rectangular studs.
With the better class of studs in order to still further prevent the head from
being bent or pushed off by accidental means I may have a second lock on the
pillar below the first which will lock the pillar if pressed too hard.
When the invention is applied as a pedigree plate-the pedigree plate proper
takes the place of the head or base plate or both. When applied to sleeve links
the two bases are united either rigidly or by a link the remainder of the apparatus
being as before.

I, SAMUEL LEIGHTON of Newmarket Lancaster, in the County of Lancaster,
Jeweller, 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 has for its object a stud which shall not easily fall out, and which
can be opened and closed without difficulty.
The invention may be understood from the following description, reference being
had to the accompanying drawings, in which :-
Figure 1 is a perspective view of the base and head of the stud separated.
Figure 2 is a perspective view of the two parts connected together, and Figure 3
a sectional elevation thereof.
Figure 4 is a perspective view of part of the head of the stud.
Figure 5 is a perspective view of the loose plate with groove, and Figure 6 a
slight modification thereof.
Figure 7 shews the invention applied to sleeve links.
じ
Referring to Figures 1 to 6 inclusive; I form the base A of the stud in the
ordinary manner of a preferably round plate supporting a pillar B in the centre.
This pillar has a small terminal flange b, and a second circular flange l'immediately
above it. The head C consists of a box formed of the ornamental dished head c for
the upper portion, and a dished plate e' for the lower portion. This flat plate has
two round holes c² ² in it, one close to the side large enough to take in the entire
flange of the pillar B, and the other in the centre just large enough to take in the
smaller circular flange on the pillar. These two holes are united by a slot just
large enough for the pillar B itself below the two flanges to slide in. Immediately
below this plate el is a loose plate D, and below this a spring E tending to press
this loose plate D up against the stationary flat plate of the head. The loose
plate D is preferably formed with a groove or depression d, which acts as a guide
for the pillar to slide along. A ridge d' may be used instead of a depression, if
desired. On one side of the stud is a depression or other indicator to show where
the large hole is. This depression forms a knob in the inside of the dished
head c which engages a slot in the loose plate D and prevents the latter from
rotating.
C
The mode of using the stud is as follows:-
The lower portion A of the stud being placed in the cuff, and the cuff buttoned
on to it, the head C is placed with the large hole immediately over the flanges of
the pillar and pressed down. The pillar enters the head. The head is now pushed
on towards the centre, the stem of the pillar sliding in the slot. The moment the
pillar reaches the centre, pressure is removed and the pressure of the spring E
causes the smaller flange b' to enter the hole c', thus locking the stud in position.
To undo it, one has merely to press the stud, and then move the head so that the
hole c approaches the pillar B. By this means the slot slides over the pillar B, and
the pillar comes opposite the larger hole c¹. The head can now be removed from
the base of the stud.
It is obvious that, although I have described the invention only for round studs,
it would be applicable for oval or rectangular studs.
When used for pedigree plates, the dished head is not ornamental, as is generally
the case for solitaires and the like, but is engraved or impressed with any given
number, name or indication.
In Figure 7 the invention is shewn applied to sleeve-links. One end of the
link is here coupled to the head A, and the other to the pillar or stud B, the said
pillar having a terminal flange b, and a second circular flange b¹ exactly as in the

page_text: preceding figure. The box head C of the sleeve-links is substantially the same as
the head C of stud, and the two parts A and C are coupled together by pressing
the pillar into the head through the hole, and then pushing it towards the centre
where it is locked in position, as already described in connection with the other
figures.
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 :-
1. The combined improvements in studs, pedigree plates for sheep, solitaires,
sleeve links, and the like, consisting in a head having a loose plate, and a spring
tending to press the plate against the base plate of said head, and the base plate
having a radial slot for the pillar to slide in, but widened at the outer end
sufficiently to admit the head, in combination with a bottom plate and pillar, the
latter having a shank capable of sliding in the slot and a flange capable of passing
the enlargement, and a device for holding the whole together and preventing the
pillar from sliding in the slot except when the head is pressed substantially as
described.
2. The general combined arrangement and construction of parts forming the
improved stud, pedigree plate, solitaire, or the like substantially as described.
