Year: 1872

page_text: LETTERS PATENT to Felix Alekan and Isidore Alekan, Jewelers, both
of No. 82, Boulevard Sébastopol, Paris, France, for the Invention
of "IMPROVEMENTS IN SCREW STUDS FOR SHIRTS, CUPPS, AND SIMILAR
PURPOSES."
COMPLETE SPECIFICATION filed by the said Felix Alekan and Isidore
Alekan at the Office of the Commissioners of Patents, with their
Petition and Declaration, on the 17th April 1872, pursuant to the
9th Section of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, FELIX
ALEKAN and ISIDORE ALEKAN, Jewelers, both of No. 82, Boulevard
Sébastopol, Paris, France, send greeting.
WHEREAS we are in possession of an Invention for "IMPROVEMENTS IN
SCREW STUDS FOR SHIRTS, CUFFS, AND SIMILAR PURPOSES," and have petitioned
Her Majesty to grant unto us, our executors, administrators, and assigns,

page_text: Her Royal Letters Patent for the same, and have made solemn declara-
tion that we are the first and true Inventors thereof.
NOW KNOW YE, that we, the said Felix Alekan and Isidore Alekan,
do hereby declare that the following Complete Specification, under our
hands and seals, fully describes and ascertains the nature of the said
Invention, and in what manner the same is to be performed, in and by
the following statemont and accompaning Drawings, that is to say :-
The object of this Invention is to insure perfect security from
casualties, such as the accidental unfastening of the article to which it
is applied, wearing the button hole by reason of the force required to:
insert it, and the loss of the button when the hole is enlarged. These
drawbacks in the systems in present use are obviated by so constructing
the bottom plate of the button that by its peculiar formation perfect
security is insured, its construction being of such a nature as to admit
of the use of a small aperture instead of the ordinary button holo.
The uses to which our improved button may be employed are various,
that is to say, for shirts, cuffs, collars, chemisettes, saddlery, harness, coach
furnishing, upholstery, gloves, boots, shoes, business papers, and so on.
The principle of the Invention being a helical system, and the features
of novelty in the Invention depending entirely in the formation of the
lower or screw plate, this may vary in form without departing from
the principle of action, for instance, the button, solitaire, or otherwise,
consists of two parts, the head or upper plate and the lower one united
by the shaft; the said button being made of any species of metal or
other substance suitable to the purpose to which it is to be applied, and
ornamented according to taste or desire.
Having now described the nature of the Invention, we will proceed to
enter more minutely into details by aid of the accompanying Drawings.
In Fig. 1 the bottom plate has a slight aperture c extending from the
edge to its centre; the edges a, a, arc bent one up and the other down.
Fig. 2 is a plan of the same. In Fig. 3 the aperture is enlarged and
semi-conical in form. In Fig. 4 it takes the form of two circles united
in the centre, and they are spherical. In Fig. 5 the plate is furnished
with double apertures c, c.
Figs. 6, 7, 8, and 9 represent several forms, all of which are equally 8
adapted to the purpose, and in cach illustration the same principle of the

page_text: screw is carried out; for instance, by inserting one of the ends of the
plate into the button hole and turning it round the plate inserts itself,
and unless by manual operation cannot possibly become detached, the
hole required for its insertion being much smaller than an ordinary
button hole, and the button or solitaire is readily fixed.
Having thus described our. Invention and the mode of carrying it into
effect, what we claim and desire to secure by Letters Patent is, the the
construction of the bottom plate on the screw system, which admits of
the employment of a much smaller hole than is usually made use of,
thereby constituting its security and facility of application; the forms
most suited to this purpose, and for which we claim the exclusive
privilege, are shown in the annexed Drawings and numbered from 1 to 9
inclusive
