JONAS HALEY, of Cleckheaton, SAMUEL PRIESTLEY, of Bradford, and ROBERT
HALL, of Pudsey, all in the County of York. "IMPROVEMENTS IN MACHINERY OR
APPARATUS EMPLOYED IN THE MANUFACTURE OF SPIRAL METALLIC BANDS."
This Invention relates to the machinery or apparatus employed in the manu-
facture of spiral metallic bands for window blinds, picture cords, spindle bands, and
various other purposes, and our present improvements are designed with the view
of making such bands of indefinite length or continuous instead of in separate short
lengths as heretofore.
Our improved machinery consists of a table or bed of length suitable to the size
of room or building in which it is placed, and at one end of which is mounted a
hollow spindle having thereon fast and loose pullies. On this spindle is also fixed
a bobbin or creel to contain the wire of which the band is to be formed. Behind
the hollow spindle is a large pulley or drum upon which the wire or cord forming
the core or maundril is wound. The end of the core is passed through the hollow
spindle and a portion of the band wire is drawn off the bobbin and twisted round
the core by hand, and the two wires thus connected are inserted between the jaws
of a small vice or nippers which are screwed together so as to take a firm hold of
the wires. This vice is capable of sliding the whole length of the machine, and is
actuated by screw extending from one end of the machine to the other.
The connection between the vice and screw is effected through a half nut or
addle which rests on the screw, but which by means of a lever or cam can be raised
lear of the screw, so that when the vice has travelled the machine in one direction

screw.
The preparations above described having been made, the machine is put into
motion, the effect of which is to wind the band wire on to the central wire or
maundril, which as it becomes covered is carried or drawn forwards by the sliding
vice and supported as it increases in length by suitable rests attached at intervals
to an endless strap passing over pullies at each end of the machine. When the
extremity of the machine is reached the vice is unscrewed, and the maundril within
the band is drawn back to the starting point, the vice is also returned and fastened
on to the "band" and end of maundril as in the first instance, and the operation
may be repeated until the whole of the wire on the creel is exhausted. After the
first length of band is finished the end is placed between two pullies, which are
caused to revolve rather faster than the band is being made so as to keep it con-
stantly in a state of tension. The revolving spindle and screw are connected by
band pullies or gearing, and according to the relation of their speeds the spirals of
the band will be open or close.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Jonas Haley, Samuel Priestley, and Robert Hall in the Great Seal
Patent Office on the 3rd September 1877.
JONAS HALEY, of Cleckheaton, SAMUEL PRIESTLEY, of Bradford, and ROBERT
HALL, of Pudsey, all in the County of York. "IMPROVEMENTS IN MACHINERY OR
APPARATUS EMPLOYED IN THE MANUFACTURE OF SPIRAL METALLIC BANDS."
This Invention relates to the machinery or apparatus employed in the manu-
facture of spiral metallic bands and various other purposes, and our improvements
are designed with the view of making such bands of indefinite length or continuous,
instead of in separate short lengths as heretofore.
Fig. 1 of the accompanying Drawings represents a side elevation of our
machine, and Figs. 2, 3, and 4 are details. A is a table or bed of length suitable to
the size of room or building in which it is placed, and at one end of which table is
mounted a hollow spindle B, having fast and loose pullies C, D. On this spindle is
also fixed a bobbin or creel E, to contain the wire of which the band is to be formed.
Behind this hollow spindle is a large pulley or drum F, upon which the wire or
cord a forming the core or maundril is wound. The end of the core is passed through
the hollow spindle, and a portion of the band wire is drawn off the bobbin E and
twisted round the core by hand, and the two wires thus connected are inserted
between the jaws of a small vice or pair of nippers G, which are screwed together so as
to take a firm hold of the two wires. This vice is capable of sliding the whole length
of the machine, and is actuated by screw H extending from one end of the machine
to the other. The connection between the vice and screw is effected through a half
nut or saddle J, which rests on the screw, but which by means of the cam K can be
raised clear of the screw, so that when the vice has travelled the machine in one
direction it can be disconnected and returned to the starting point without reversing
the screw.
The preparations above described having been made the machine is put into
motion, the effect of which is to wind the band wire on to the central wire or
maundril, which as it becomes covered is carried or drawn forwards by the sliding
vice and supported as it increases in length by suitable rests L attached at intervals
to an endless strap passing over pullies M at each end of the machine. The machine
is so constructed that it will stop when a certain length of spiral wire has been.
made. This is effected by a bracket attached to the nipping jaws coming into
contact with and pressing down one end of the lever m and releasing the rod n of
the strap guide p, which removes the driving strap from the fast to the loose pulley.

and stops the machine; the rod n is drawn forward by a spring 8. When the ex-
tremity of the machine is reached the vice is unscrewed and the maundril within the
band is drawn back to the starting point by means of the sliding weight N and
cord which passes round a pulley P on the drum F; the vice is also returned and
fastened on to the band" and end of maundril as in the first instance, and the
operation may be repeated until the whole of the wire on the crcel is exhausted.
After the first length of band is finished the end is placed between two pullies which
are caused to revolve rather faster than the band is being made, so as to keep it
constantly in a state of tension. These pullies, Q and R, are caused to revolve by
means of the band S passing round the same, and also round a pulley connected to
the pulley M carrying the endless belt, the said band being nipped by the catch T
when the vice is running out, but which catch is so hinged as to slip over the band
when the vice is running back again. The revolving spindle and screw are con-
nected by band pullies U, V, W, X, and according to the relation of their speeds the
spirals of the band will be open or close.
Figures 2, 3, and 4 are details of the bobbin or creel E. This is composed of two
principal parts & and e. The hollow shell d is fixed on the spindle, and revolves
with it; the outer part e fits loosely to the part d, so as to revolve therewith, but it
is free also to move upon the surface of the shell or drum d. A guide f is attached
to the drum & for conducting the wire on to the core, and a support y is also
attached for holding the said core firmly at the point where the wire is wound on.
This support g has a slot or notch in the circumference for convenience in passing
the band wire when commencing a band. It will be seen that as the band wire is
supplied by the creel it must necessarily turn rather slower than the spindle, which
is the object of its peculiar construction. If the wire is very loose upon the
drum d, it will be wound on so much slacker, and if it is tight on the drum
the wire will also be tightly wound, and for regulating this we employ brakes,
consisting of plates of metal or other suitable substance h, attached to the drum,
and bearing on the rim of the bobbin or creel, the pressure being regulated by
spring and screw j. Should the wire break between the band and guide f, the
spring catch will hold the loose end firmly and prevent the wire on the creel
from springing or becoming slack.
In making very light spirals it is not necessary to use all the parts shewn, as a
short maundril may be passed through the hollow spindle, and secured so as to be
stationary, in which case the motion of the machine may be continued indefinitely
as the pressure of ingoing wire forces the spiral off the end of the maundril into a
can or other receptacle placed to receive it."
Having now described the nature of our Invention, and the manner in which the
same is to be performed, we would remark in conclusion that we do not limit our-
selves to the exact details of parts we have explained and shewn, as the same may
of course be varied or modified without in any way departing from the nature and
principal of our Invention, but what we do claim and desire to be secured to us
by Letters Patent is, the manufacture of spiral metallic bands of indefinite or con-
tinuous lengths as herein shewn and described.
In witness whereof, I, the said Jonas Haley, for and on behalf of myself and
the said Samuel Priestley and Robert Hall, have hereunto set my hand and
seal, this First day of September, in the year of our Lord One thousand eight
hundred and seventy-seven.
