NOW KNOW YE, that I, the said William Hamer, do hereby declare the
nature of my said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement
(that is to say):
:
:
This Invention relates to the removal of the sliver from the can or coiler,
and consists in placing underneath the material a spring of metal, so that as
the sliver is removed from the top of the can or coiler its lower portion is
raised upwards by the spring and thereby prevents breakage:
The manner in which my Invention is to be performed will be clearly under-
stood by referring to the figures and letters on the accompanying Sheet of
Drawings, in which Fig. 1 is a vertical section of a can having in it a plate and
coiled spring for assisting the removal of the sliver; Fig. 2 a plan of the
bottom of the can; and Fig. 3, a plan of the plate only.

page_text: In Fig. 1 the can is shewn at a, the plate at b, and the coiled spring at c.
In Fig. 2, d represents a hole in the bottom of the can for admitting air
during the removal of the sliver; and in Fig. 3, the plate is shewn with
portions of its circumference cut away as at e, to allow it to pass within the
bead or moulding at the top of the can when it is placed in the inside.
The spring of metal is formed of round, square, or other shaped wire, and is
made of any number of coils according to the size of the can and weight of
material, and is applied to cans or coilers of all descriptions and purposes.
When the sliver is drawn up in the usual manner it frequently becomes
uneven, stretched, torn, or broken, but the application of my improved spring
and plate causes the sliver to be gradually raised up from the bottom to near
the top of the delivery, and by taking off the strain enables the sliver to bo
made as fine as possible, and prevents, defects or breakage when leaving
the can.
By the employment of my improved spring and plate the cans may be
deeper and larger in diameter than usual, and thereby hold more material;
they also require less tending and shifting, and have less wear and tear.
Another advantage is, that the pressure upon the sliver commences soon after
it has begun to enter the can and thereby enables it to be laid even and
regular.
Having now described the nature and particulars of my said Invention, and
the manner in which the same is to-be performed, I desire it to be understood
that I claim as my Invention the application of a moveable plate and spring to.
cans and coilers used in the preparation of cotton and other fibrous materials,
as herein described and illustrated in the accompanying Sheet of Drawings.
In witness whereof, I, the said William Hamer, have hereunto set my
hand and seal, this Twelfth day of August, in the year of our Lord
One thousand eight hundred and sixty-two.
Signed, sealed, and delivered by the
within-named William Hamer, in
the presence of
E. J. HUGHES,
Patent Agent,
Manchester.
WILLIAM HAMER. (L.S.)
