Metallic Coils or Spirals.
We, REGINALD WILLIAM JAMES, of 75 Tyrwhitt Road, Brockley, in the County of
Kent, Engineer, and WILLIAM STURCKE of Wood Street, Old Street, in the County
of Middlesex, Mattress spring manufacturer, do hereby declare the nature of this
invention to be as follows:-
Our invention relates to machinery for twisting and fastening down the ends of
wires, and is particularly applicable for fastening metallic coils or spirals, such as
the springs used in cushions, mattresses, etc., either one to the other, so as to
attach two or more together, or to fasten down one end upon another part of the
said spiral, to avoid injurious contact of a projecting end with the cloth or stuff
by which it may be covered.
Our improved machine consists of a geared disc provided with a slot extending
from the circumference to the centre, and providing a certain clearance about that
centre, a recess being also provided on the face of the said disc alongside the slot,
which is furnished with a tangential shoulder by which the end of the wire to be
twisted is bent over by the revolution of the said disc.
The revolution of the said fastening disc is effected by a shaft and handle,
carrying a pinion, gearing into the aforesaid geared disc.
In order that the wire may be bent and twisted by the recess and shoulder of
the aforesaid fastening dise, it is necessary that that part of the wire which is to
be twisted should be first bent at right angles to the remaining portion of the coil
or spiral, the length of such bent portion determining exactly the number of laps
of the twisted part of the wire around the core.
To effect the seizing of the spiral or coil for preliminary bending and for after
twisting up and fastening, we use a pair of clamps, which are mounted on a pivotted
arm, so as to be capable of travelling through a certain are about an axis, by means
of a hand lever. The said gripping clamps consist of one, a fixture, and the other,
a movable one, the movable clamp being raised or lowered conveniently by means of
a foot treadle and counter balance weight or springs.

page_text: In order to prepare the spiral or coil for twisting and fastening, it is first
placed in the said clamps in that position farthest from the fastening disc, an end
of the coil being allowed to project up to an adjustable gauge, of such desired
length as will make a suitable lap or fastening. The bending is effected in this
position of the clamps by another hand bell-crank lever, carrying the aforesaid
adjustable gauge, and provided at its extremity with a roller, which, being raised
forcibly underneath the projecting end of the wire fastened in the clamp, bends the
aforesaid projecting end upwards at right angles to the remaining portion of the
coil.
The coil is now ready for twisting and fastening either to another coil, or for
fastening down on to itself, so to prevent the projection of its extremities.
To effect this final twisting or fastening down, the clamp holding the spiral is
moved through its arc of travel up to the aforesaid slotted twisting or fastening
disc. The body of the coil enters the twisting or fastening disc through the afore-
said radial slot, the aforesaid bent end lying against the recessed shoulder on the
face of the twisting or fastening disc.
The twisting disc or fastener is now revolved by means of the before mentioned
geared shaft and handle, the shoulder on the said fastening disc causing the bent
end of the wire to be lapped round another portion of the said coil, or the portion
of an adjoining coil as may be desired. A secure twisted lap is thus effected, care
being taken that the recess about the centre of the fastening disc is of exactly
suitable dimensions to allow the twisting of the wire without any clearance, and
thus ensuring a tight immovable fastening.

Improvements in Machinery for Fastening the Ends of Wires or
of Metallic Coils or Spirals.
-
We, REGINALD WILLIAM JAMES, of 75 Tyrwhitt Road, Brockley, in the County of
Kent, Engineer, and WILLIAM STURCKE, late of Wood Street, Old Street, but now of
87 Great Eastern Street, both in the County of Middlesex, Mattress spring manu-
facturer, do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :-
:-
Our invention relates to machinery for twisting and fastening down the ends of
wires, and is particularly applicable for fastening metallic coils or spirals, such as the
springs used in cushions, mattresses, etc., either one to the other, so as to attach two
or more together, or to fasten down one end upon another part of the said spiral, to
avoid injurious contact of a projecting end with the cloth or stuff by which it may be
covered.
In order that our invention may be the better understood, we now proceed to describe
the same, reference being had to the drawings hereunto annexed, and to the letters
and figures marked thereon. Like letters refer to like parts throughout the figures.
Fig. 1 is an elevation of our machine.
Fig. 2 is a part sectional plan of the same.
Fig. 3 is a plan and section through the apparatus by which the end of the wire is
first bent over.
Fig. 4 is a front & side elevation respectively of the disc which completes the
bending of the wire.
Our improved machine consists of a geared disc A, provided with a slot a, extending
from the circumference to the centre and providing a certain clearance about that
centre, a recess B being also provided on the face of the said disc alongside the slót,
which is furnished with a tangential shoulder by which, the end of the wire to be
twisted is bent over by the revolution of the said disc. The said disc is mounted in
a frame plate C, which acts as a bearing, having a slot corresponding to the slot in
the disc, and forms part of or is attached to a bed plate D, which may be fixed to any
bench or working table. The revolution of the said fastening disc A is effected by
the pinion E gearing into the aforesaid geared disc A, and rotated by a handle b.
In order that the wire may be bent and twisted by the recess and shoulder B of the
aforesaid fastening disc A, it is necessary that that part of wire which is to be
twisted should be first bent at right angles to the remaining portion of the coil or
spiral, the length of such bent portion determining exactly the number of laps of
the twisted part of the wire around the core. To effect the seizing of the spiral or
coil for preliminary bending and for after twisting up and fastening we use a pair of
clamps FF, which are mounted on the arm G, pivotted at C, and are thus capable of
being caused to travel through an arc d by means of a hand lever e.
The said gripping

page_text: clamps consist of one part a fixture, and the upper part a movable clamp, which is
raised or lowered by the lever H, pivotted at f, by means of a foot treadle attached
to the rod g, a counterbalance weight or spring being provided to left it when
required.
In order to prepare the spiral or coil for twisting and fastening, it is first placed in
the said clamps in that position farthest from the fastening disc as shown in fig. 3,
an end of the coil being allowed to project up to an adjustable gauge of such desired
length as will make a suitable lap or fastening. The bending. is effected in these
clamps by a hand lever K which is provided at its extremity with a sliding rod L and
a roller. When this sliding bar and roller is then forced forward by the hand
lever K, the end of the wire is bent inwards and under the other portions of the coil
at right angles to its original direction, as shown in figure 5.
The coil is now ready for twisting and fastening either to another coil or for
fastening down on to itself, so as to prevent projection of its extremities.
To effect this final twisting or fastening down, the clamp holding the spiral' is moved
through its arc of travel d up to the aforesaid slotted twisting or fastening disc A.
The body of the coil enters the said twisting or fastening disc A through the afore-
said radial slot a, the aforesaid bent end lying against the recessed shoulder B on the
face of the twisting or fastening disc.
The twisting disc or fastener is now revolved by means of the aforesaid geared
pinion E and handle b, the shoulder B on the said fastening disc A causing the bent
end of the wire to be lapped around another portion of the said coil, or the portion of
an adjoining coil as may be desired. A secure twisted lap is thus effected, care being
taken that the recess about the centre of the fastening disc is of exactly suitable
dimensions to allow of the twisting of the wire without any clearance, and thus ensuring
a light immovable fastening.
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 is.
1st. In a wire tying or fastening machine a slotted revolving fastening disc provided
with recessed shoulder, in combination with a treadle clamp to grip the wire, moving
in a radial are and with a bending device to bend inwards the end of the wire,
substantially as & for the purposes described.
2nd. The general construction & mode of operation of the machine for fastening
the end of wires substantially as and for the purposes described.
