of Gill Boxes.
We, WILLIAM TERRY of Dudley Hill, near Bradford, Yorkshire, Machine Wool
Comber, and WALTER BATTY of the same place, Mechanic, do hereby declare the
nature of our invention for "IMPROVEMENTS CONNECTED WITH THE CALENDAR OR
DELIVERY ROLLERS OF GILL BOXES "
and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
Our invention has reference to the calendar or delivery rollers of gill boxes,
which rollers are employed to receive the sliver of fibre as it issues from the
machine.
After the sliver passes between the calendar rollers it drops into a sliver can
placed underneath to receive it, and to prevent the loose fibres of the sliver being
carried around by the said rollers, the lower surface of the rollers rest and rotate
upon certain devices called "rubbers" which prevent the body of the sliver from
following the rollers, although many loose fibres adhere to them.
These "rubbers" have hitherto been composed of wood, or metal lined with cloth,
felt, or other like material, which in practice is found objectionable, because gritty
or hard substances in the fibre lodge in the cloth which in time greatly damages
the rollers by cutting grooves therein, in addition to which the rollers take a
considerable amount of driving in consequence of the frictional contact with the
cloth "rubbers," which soon wear away and have to be re-placed by new ones, or
relined with cloth.
According to our invention we dispense with the cloth lined "rubbers" and use
instead thereof metal "rubbers" which are not placed in actual contact with the
calendar rollers, but nearly so, consequently there is no friction, nor wear and tear,
whilst the power to drive same is very much reduced, and as this form of rubber is
not lined, gritty substances cannot lodge in them to damage the rollers, as is the
case with cloth lined "rubbers."
In order that our invention may be more readily understood, we herein make
reference to the accompanying Sheet of drawings, wherein Figure 1 is the end
elevation of a pair of calendar rollers having our invention applied thereto,

roller B, and passing between the calendar or delivery rollers C, D, and E is the
sliver can, all arranged in the ordinary manner.
Our improvements are shewn at F, which is a double concave casting attached
to the plate G, and placed almost in contact with the underside of the rollers.
This concave casting is kept in position by means of rods a and brackets b resting
upon the axles c of the rollers C and D, which brackets are kept in contact with
the axles c by spiral springs d, a suitable opening is made in the concave casting F,
and plate G for the sliver to pass through. This "rubber" in practice we have
found very effective, not only allowing for the free passage of the sliver, but it does
not possess the disadvantages found in the cloth lined "rubber" whilst at the same
time it is very durable and requires no attention.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim as our Invention is;
The use of the double concave metal rubbers F, when used in combination with
the calendar or delivery rollers of gill boxes, in the manner substantially as herein
set forth and shewn in the drawings.
