Year: 1876

page_text: LETTERS PATENT to Wilfred Cammack and Robert Cammack, both of Orms-
kirk, in the County of Lancaster, Watchmakers and Jewellers, for the Inven-
tion of "IMPROVEMENTS IN DRESS FASTENINGS."
Sealed the 12th December 1876, and dated the 14th June 1876.
PROVISIONAL SPECIFICATION left by the said Wilfred Cammack and Robert
Cammack at the Office of the Commissioners of Patents on the 14th June
1876.
WILFRED CAMMACK and ROBERT CAMMACK, both of Ormskirk, in the County of
Lancaster, Watchmakers and Jewellers. " IMPROVEMENTS IN DRESS FASTENINGS."
This Invention relates, first, to improved constructions of studs, solitaires, and
other dress fastenings employed in securing or attaching together articles of dress,
and consists,
First. In forming a stud, solitaire, or other dress fastening in two parts, a front
and a back piece. The back piece is formed with a barrel or sleeve provided at its
outer end with projecting lugs or catches. The front piece is provided with a pin
over which the barrel or sleeve of the back piece slides, and is fitted with one or
two, preferably two, spring bolts. The spring bolts are formed with indentations
to receive and hold the projections or lugs on barrel or sleeve of the back piece
when pressed home and turned a quarter round. The spring bolts are enclosed in a
cover which allows the back piece to enter in one position but prevents its with-
drawal when in holding position. The parts are freed by pressing the bolt or bolts
and turning the front piece.
Second. In forming studs, solitaires, or other dress fastenings with a retaining
loop hinged to the back of the stud, solitaire, or like fastening at one end, the free
end being formed with lugs or projections, as above described. One or more
indented spring bolts is or are used, as described under the first part. When the
free end is pressed home the indentation in the spring bolt slides past the stem and
secures the lugs or projections beneath. The parts are freed by pressing the spring
bolt or bolts and raising the loop.

Figs. 1, 2, 3, 4, 5, and 6 are views of a solitaire constructed under our Invention.
Fig. 1 is a back view of the front piece; Fig. 2, same with cover removed; Fig. 3,
a back view of the back piece; Figs. 4 and 5, side views of back piece; and Fig. 6,
a side view of the front piece. a, back piece; b, barrel or sleeve; c, projecting
lugs or catches; d, front piece; e, pin; f, spring bolts.
In practise the barrel b is caused to slide over the pin e until the lugs or catches c
enter the openings g in the cover h; the piece a is then caused to turn until in the
position shown in Fig. 2, in which position the cover h prevents by means of the
lugs or catches the withdrawal of the back piece, and the bolts of prevent the back
piece turning so as to bring the lugs or catches opposite the openings g.
Figs. 7, 8, 9, and 10 show views of a modification of solitaire in which only one
lug and one spring bolt is employed. The same letters refer to the same parts as
in Figs. 1, 2, 3, 4, 5, and 6. The action is similar except that in unfastening the
lug or catch c is obliged to stop opposite the opening g.
Figs. 11, 12, 13, 14, 15, 16, 17, 18, and 19 show a further modification of solitaire
in which the lugs project internally, and instead of catching under the cover h catch
in the notches in the pin. The action is similar to that above described.
Figs. 20, 21, 22, and 23 illustrate another modification of solitaire in which only
one internal lug or catch is used.
Figs. 24, 25, 26, and 27 are views illustrative of a soltaire or dress fastening con-
structed under the second part of our Invention. j, solitaire provided with the
hinged loop having lugs ; m, spring, bolt which locks over the lugs / when
'closed.
It will be obvious that many modifications of solitaires can be made without
departing from our Invention, and that the fastenings above set forth are applicable
to sleeve links, breast pins, purses, and the like.

page_text: Having now described the nature of the said Invention so that others will be
enabled to carry our improvements into effect, we claim,―
Under the first part, the construction of solitaires with the front and back piece
interlocking, substantially as set forth.
Under the second part, the improvements substantially as set forth.
In witness whereof, we, the said Wilfrid Cammack and Robert Cammack,
have hereunto set our hands and seals, the Twelfth day of December, in
the year of our Lord One thousand eight hundred and seventy-six.
