IMPROVEMENTS IN THE MANUFACTURE OF CERTAIN KINDS OF SPECTACLE FRAMES
Year: 1861

page_text: LETTERS PATENT to Charles Eyland, of Walsall, in the County of Stafford,
Manufacturer, for the Invention of "IMPROVEMENTS IN THE MANUFACTURE
OF CERTAIN KINDS OF SPECTACLE FRAMES."
Sealed the 9th July 1861, and dated the 22nd February 1861.
COMPLETE SPECIFICATION filed by the said Charles Eyland at the Office.
of the Commissioners of Patents, with his Petition and Declaration, on
the 22nd February 1861, pursuant to the 9th Section of the Patent Law
Amendment Act 1852.
I, CHARLES EYLAND, of Walsall, in the County of Stafford, Manufacturer, do,
hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE.
MANUFACTURE OF CERTAIN KINDS OF SPECTACLE FRAMES," and the manner in
which the same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof, reference being had to the
Drawings hereunto annexed, and to the letters and figures marked thereon,
that is to say:-
My Invention refers to the manufacture of such spectacle frames as are or
may be made of metal, and it consists in producing such frames complete.
from solid pieces of metal, so as to dispense altogether with soldering.. This I
effect by stamping out the blanks for each piece from rolled sheets of metal
by means of suitable dies in a press or stamp, the several parts being also
shaped and brought into form by similar dies.
The process will be more readily comprehended by reference to the
accompanying Drawings, in which Figure 1 represents the form of blank I
produce for the front of the spectacles, the lugs or projections (a, a,) for the
joint being stamped out at the same time; these lugs are then to be slit down
the centre of each, as seen in the Drawing, afterwards laid in a press, and

page_text: each half turned at right angles to its former position, as seen at (Figures 2
and 7), they are then to be pierced with two holes in each, one for the screw
and one for the rivet. Figure 3 shews one of the side pieces or temples also
struck or cut out of sheet metal, one end being looped, as at (6), and the
other shaped for the joints; these side pieces or temples have now to undergo
another operation of the press or stamp, the loop (b) requires to be turned
half round, that is to say, at right angles with the rest of the piece; this also
is effected, firstly, by hand, and afterwards by suitably formed dies in a press
or stamp, and by the same means the opposite end (c) of the temple is caused
to assume the form seen in Figure 4. The slightly raised part seen at (D)
being produced from the extra thickness of metal left on that end of the
temple. The front parts having been grooved for the glasses, all the pieces
are now ready to be put together, as shewn in Figures 5, 6, and 7; Figure 8
merely represents a pair of spectacles with a crank bridge made by the same
process. It will thus be seen that I am enabled by these improvements to
manufacture single temple metal spectacle frames in three pieces of solid
metal without the use of soldering, and double temple spectacles may be made
in five pieces by the same process, of course not including the screws or
rivets.
Having thus described the nature of my said Invention, and in what
manner the same is to be performed, I wish it to be understood that I do not
claim the process of stamping out the blanks for metal spectacle frames other-
wise than as I have herein described it, that is to say, with the lugs or pro-
jections for the joints formed on the blanks by the same process, as I am well
aware that the shaping of spectacle frames by stamping out the fronts, and
afterwards soldering on or otherwise attaching the lugs or joint pieces is old
and well known in the trade, and I have myself practised it more than twenty
years since; but that which I claim as my Invention is, the several improve-
ments described in the manufacture of metal spectacle frames by stamping
or cutting out of the solid metal each several part entire, and shaping and
finishing the same in dies and by pressure, and without soldering, in manner
herein more fully set forth and specified.
In witness whereof, I, the said Charles Eyland, have hereunto set
my hand and seal, this Twenty-first day of February, in the year of
our Lord One thousand eight hundred and sixty-one.
CHARLES EYLAND. (L.B.)
