A NEW OR IMPROVED MACHINE OR AP: PARATUS FOR MAKING SPIRAL METALLIC BANDS
Year: 1876

page_text: LETTERS PATENT to Robert Hall, of Horsforth, near Leeds, in the County of
York, Mechanic, and Samuel Priestley, of Bradford, in the same County,
Accountant, for the Invention of "A NEW OR IMPROVED MACHINE OR AP:
PARATUS FOR MAKING SPIRAL METALLIC BANDS."
PROVISIONAL SPECIFICATION left by the said Robert Hall and Samuel
Priestley at the Office of the Commissioners of Patents on the 14th August
1876.
ROBERT HALL, of Horsforth, near Leeds, in the County of York, Mechanic, and
SAMUEL PRIESTLEY, of Bradford, in the same County, Accountant. "A NEW OR
IMPROVED MACHINE OR APPARATUS FOR MAKING SPIRAL METALLIC BANDS."
This Invention relates to improved machinery to be employed for twisting wire
into a spiral form for the purpose of forming bands or cords of sufficlent length to be
used instead of cords formed of fibrous substances, for window blinds, bands for
drawing the spindles of spinning machinery, and other purposes.
Our machine or apparatus consists of a rail or bed rather longer than the band
which it is desired to make. Upon this bed, at one end, is mounted a spindle
(parallel to the bed), and pulley or pullies, and at the other end of the bed is a
swivel stud. A wire is stretched between the spindle and swivel stud, and this
wire serves as a core or mandril upon which to wind other wire spirally. On each
side of this wire is another wire of the same length stretched and secured at the
ends. The three wires then placed carry a "rider" consisting of a plate through
which the wires are passed previous to the ends being secured. This rider acts a
self-adjusting guide and the feeder of what we will call the "band wire," the
action being as follows:-
-
On commencing to make a band the rider is placed close up to the end of the spindle ;
the "band wire" (contained upon a creel or swift) is passed over tension pins on the
rider and made fast to the spindle. The spindle is then caused to revolve, and the

page_text: central wire or inandril likewise revolves, and the "band wire" is wound upon the
central wire. As the coil increases in length it presses against the "rider" and
causes it to slide upon the wires.
Hinged supports are placed at intervals to prevent deflection of the central wire,
and these supports consist of two arms placed at an angle to each other, the hinge
being at the point of junction. The "rider" in its course comes in contact with these
supports, and as it presses the arm in front downward it elevates the other arm in
the rear, so that after the commencement the machine requires no attention
until the band is completed.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by:
the said Robert Hall and Samuel Priestley in the Great Seal Patent Office
on the 14th February 1877.
ROBERT HALL, of Horsforth, near Leeds, in the County of York, Mechanic, and
SAMUEL PRIESTLEY, of Bradford, in the same County, Accountant. ** IMPROVED
MACHINERY OR APPARATUS FOR MAKING SPIRAL METALIC BANDS."
This Invention relates to improved machinery to be employed for twisting wire
into a spiral form for the purpose of forming bands or cords of sufficiont length to
be used instead of cords formed of fibrous substances, for window blinds, bands
for driving the spindles of spinning machinery, and other purposes.
In order that our Invention may be more fully understood we herein give refer-
ence to the accompanying Sheet of Drawings of a machine constructed according to
our Invention.
Our machine or apparatus consists of a rail or bed A rather longer than the
band which it is desired to make. Upon this bed, at one ond, is mounted a spindle
B, on which are fast and loose pullies C and D, and at the other end of the bed is a
swivel stud E. A wire F is stretched between the spindle and swivel stud, and
this wire serves as a core or maundril upon which to wind other wire spirally. On
each side of this wire F is another wire G of the same length, stretched and secured
at the ends. The three wires thus placed carry a "rider" consisting of a plate H,
through which the wires are passed previous to the ends being secured. This
"rider," shewn in detail, Fig. 3, acts as a self-adjusting guide and feeder of what wo
call the band wire J, and is provided with pins a between which the band wire is
threaded for the purpose of straightening and keeping the same in a state of tension.
On commencing to make a band the "rider" is placed close up to the end of the
spindle. The band-wire (contained upon a creel or swift) is passed over the tension
pins on the "rider" and made fast to the spindle. The spindle is then caused to
revolve, and the central wire or maundril likewise revolves, and the "band wire" is
wound upon the central wire. As the coil increases in length it presses against the
"rider" and causes it to slide upon the wires.
Hinged supports K are placed at intervals to prevent deflection of the central
wire, and these supports consist of two arms placed at an angle to each other, the
hinge being at the point of junction. The "rider" in its course comes in contact
with these supports, and as it presses the arm in front downward it elevates the
other arm in the rear, so that after the commencement the machine requires no
attention until the band is completed. When the band is completed one end of the
maundril or central wire is loosened, the "band wire" is freed at each end and
drawn off the maundrils.
Having thus described the nature of our Invention we would have it understood
that we claim,—
Firstly. The general construction of the machine or apparatus as herein shewn
and described.

page_text: Secondly. The use of the maundril or central wire F as and for the purpose
herein shewn and described.
In witness whereof, I, the said Robert Hall, for and on behalf of myself and
the said Samuel Priestley, have hereunto set my hand and seal, this Twelfth
day of February, in the year of our Lord One thousand eight hundred and
seventy-seven.
