IMPROVEMENTS IN STUDS OR CLASPS."
Year: 1876

page_text: LETTERS PATENT to William Henry Douglas, of Stourbridge, in the County
of Worcester, Jeweller, for the Invention of "IMPROVEMENTS IN STUDS OR
CLASPS."
PROVISIONAL SPECIFICATION left by the said William Henry Douglas at
the Office of the Commissioners of Patents on the 15th September 1876.
WILLIAM HENRY DOUGLAS, of Stourbridge, in the County of Worcester,
Jeweller. "IMPROVEMENTS IN STUDS OR CLASPS."
This Invention consists of improvements in the description of studs or clasps,
which are formed by two face and back plates connected by one link plate, and
governed or kept in place by a spring, in other words, two studs are employed, one
secured to the link plate, the other free. The free stud has its shank continued
through the back plate, and forming a slight projection thereon; round this pro-
jection a groove or necking is formed, the link plate is pierced at the end which
receives the free stud by a slot to receive the necked projection on the free stud,
which on being inserted through the slot is engaged by a spring catch fixed upon
the under side of the link plate taking into the necking, and pressing it against the
edge of the slot, thus retaining the free stud until released by the finger from the
pressure of the spring.
By another arrangement I connect the two studs by a system of links, forming
what is known in mechanics as lazy tongs.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed by
the said William Henry Douglas in the Great Seal Patent Office on the
14th March 1877.

page_text: I will now proceed to describe my Invention more fully in detail by aid of
the accompanying Drawings, reference being had to the letters and figures marked
thercon.
Figure 1 represents a clasp applicable to collars, cuffs, or gloves, or other articles
of dress, in which (A) is a stud, having attached to it a link plate (B) pierced at (a)
to receive a collared nut (b) at the back of the loose stud (C). When the stud (C)
is inserted into the slot (a) it becomes engaged by a spring catch (d) fixed upon
the top of the link plate (B), by means of the spring catch (d) bearing against the
back plate (e) of the stud (C), thus forcing the stud (C) back, and causing the
collared nut (b) to catch against the edge of the slot (a), and become secured until
released by the finger.
Figures 2 and 3 shew modifications of my Invention, more particularly adapted
to the fastening of gloves (D); Figures 2 and 3 represent the link plate of one clasp
pierced with the slot (f), as shewn by the views of the under side of the clasps;
and (E), Figures 2 and 3, represent the other clasp having a link plate (g), upon the
under side of which is a nut (h), which is engaged in the slot (f) by passing the
link plate (g) through a band (i) on the clasp D. The nut (h) is kept within the
slot (f) either by the springs as at (1), Figure 2, or by forming the face plate, of
the one clasp into a spring as at k, Figure 3; these clasps may be further secured
by forming a lip (1) at the end of the link plate (g), as shewn in Figure 2, which
will catch upon the back of the clasp (D). These clasps or studs may be attached
to the glove, by each portion being made with a necking and back plate, as the
stud (E), Figures 2 and 3, or one stud may be thus formed to pass through the
ordinary button hole of the glove, and the other attached to the other side of the
glove by a small broach pin, as shewn at (m), Figure 2, or both portions may be
attached to the glove by means of broach pins, or one portion may have the
necking and back plate as before described, and the other have a slot formed in its
back plate, as at (n), Figure 3, so that it may be slid over the button of the glove,
as shewn at (0) Figure 3.
Having thus described the object and nature of my said Invention, and the
manner in which the same is to be carried into effect, I claim without limiting
myself to these precise details the several improvements in studs or clasps, as herein
more fully set forth and specified.
In witness whereof, I, the said William Henry Douglas have hereunto set my
hand and seal, this Twelvth day of March, in the year of our Lord One
thousand eight hundred and seventy-seven.
WILLIAM HENRY DOUGLAS. (L.B.)
