TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALEXANDER
MELVILLE CLARK, of 53, Chancery Lane, in the County of Middlesex,
Patent Agent, send greeting.

NEEDLES," and have petitioned Her Majesty to grant unto me, my exc-
cutors, administrators, and assigns, Her Royal Letters Patent for the
same, and have made solemn Declaration that it has been communi.

page_text: cated to mo from abroad by Harry Mann Jenkins and Henry Baylis,
both of the City, County, and State of New York, United States of
America.
NOW KNOW YE, that I, the said Alexander Melville Clark, do hereby
declare that the following Complete Specification, under my hand and
scal, 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
statement, reference being had to the accompanying Drawing and to the
letters and figures marked thereon (that is to say) :—
This Invention relates to that class of needles which are provided with
slots or openings for the passage of the thread into the eye, and tho
nature of the Invention consists in the peculiar formation of such slot
for the purpose of facilitating the introduction of the thread into the
oyc, and also to more effectually prevent its withdrawal in sewing, as will
be herein-after more fully set forth.
In order to enable others skilled in the art to which the Invention
appertains to make and use the same, I will now proceed to describe its
construction and operation, referring to the annexed Drawing, which
represents a side elevation of a needle embodying the Invention.
A represents a needle made of ordinary shape, provided at or near the i
head with an eye a. This end of the needle is split, so as to form an
opening or passage into the cyc a, said split being made on two curves
and y, as shown, and the last curve entering the eye at the side of its
upper end, so as to leave a solid bearing b at the end of the cyc for the
thread.
The split end of the needle is held closed by the natural spring of the
metal, and opens to the pressure of the thread from the outside, said
thread being forced in between the two rounded ends i, i, of said split
end.
This construction of the head of the needle does not weaken the
needle, as it is in the thickest part thereof that the opening is made, and
the thread cannot slip through said opening, as it has a solid bearing or
scat to rest against at the end of the cyc.
Having described the nature of the Invention and the manner for per-
forming the same, I declare that what I claim as new and desire to secure
by Letters Patent is, in a bifurcated needle, the combination with the

page_text: eye a of ordinary construction of the entering cleft or slit x, y, S shaped,
or the form of a compound curve, the recessed scat b, to form a solid
bearing for the thread, and the rounded guide ends i, i, all constructed
and arranged substantially as and for the purpose herein set forth.
In witness whereof, I, the said Alexander Melville Clark, have
hereunto sct my hand and scal, this Twenty-third day of
December, in the year of our Lord One thousand eight hundred
and seventy-four.
Witness,
HY. SWALES,
53, Chancery Lane,
London.
