Improvements in Machines for Coiling Wires for Mattresses and
other such articles.
I EDWARD SAMUEL BOND of Crown Machine Works Lower Hurst Street
Birmingham in the County of Warwick Engineer and Machinist do hereby
declare the nature of my said invention to be as follows:-
My invention has for its object improvements in machines for coiling wires for
mattresses & other such articles by which such coils are automatically stopped
for the cutting of the coil at the required length and the machine automatically
readjusted ready for starting the coiling of the next wire and this is so effected
that the machine may be fixed upon any ordinary table without any provision being
made for the deep dropping of a weight as previously such machines could only be
used in upstairs premises or with a well for allowing of the travel of the cord
& weight. The sudden jerk of the long fall of such weight was also liable to
frequently break the catgut or other supporting cord used and this is obviated by.
my improvements.
In carrying my invention into effect the grooved rolls for feeding the wire into
the coiling tool are mounted one above the other and geared together the shaft of
the lower roll being carried through the housings and a thread formed on same
upon which a carriage is provided to travel as the shaft revolves. This shaft.is
geared at its other end with the driving shaft which is preferably situated above
and upon which a loose sleeve bearing the band pulley is mounted. Between these
two shafts a double lever is pivotted the one end being arranged to operate a
clutch between the driving shaft and the loose sleeve and the other end between
the screw for operating the carriage & the lower shaft a band spring being provided
to press against the clutch so as to keep both clutches normally engaged until an
adjustable screw pin which is mounted upon the carriage which is travelling presses
the clutch out of gear with both top & bottom shaft. Upon the bottom shaft a
pinion is mounted which gears with spur of considerably increased size & with
this spur a drum is connected to which the catgut for supporting the weight is
attached so that as the machine is in operation for coiling the length of wire the
weight is wound up until the travelling carriage disconnects the clutch as before
described which disconnects the motion of the band pulley sleeve from the driving
shaft thus stopping the machine & at the same time disconnecting the screw upon
which the carriage is travelling in the one direction which allows the weight to
revolve the spur & pinion in the reverse direction which revolves the screw &
brings the carriage back ready for starting again. The starting of the machine is
effected by a handle & cam the turning of which by hand throws the clutches into
gear. The clutch may be effected by dog teeth or preferably by friction cones.
It will thus be seen that by the use of the spur & pinion the travel of the weight
for bringing back the carriage is materially reduced which is a considerable.
advantage.

I EDWARD SAMUEL BOND of Crown Machine Works Lower Hurst Street,
East Birmingham in the County of Warwick Engineer and Machinist do hereby
declare the nature of my said invention & in what manner the same is to be
performed to be particularly described and ascertained in & by the following
statement:-
My invention has for its object improvements in machines for coiling wires for
mattresses and other such articles by which such coils are automatically stopped
for the cutting of the coil at the required length and the machine automatically
readjusted ready for starting the coiling of the next wire and this is so effected
that the machine may be fixed upon any ordinary table without any provision being
made for the deep dropping of a weight as previously such machines could only be
used in upstairs premises or with a well for allowing of the travel of the cord and
weight. The sudden jerk of the long fall of such weight was also liable to
frequently break the catgut or other supporting cord used and this is obviated by
my improvements.
In order that my invention may be clearly understood and more easily carried
into practical effect I have appended hereunto a double sized sheet of drawings
upon which I have fully illustrated the nature of my said invention.

Figure 2 is a cross section of same.

the
In carrying my invention into effect the grooved rolls A & A¹ for feeding the
wire into the coiling tool are mounted one above the other and geared together
the shaft a of the lower roll A¹ being carried through the housings B and a
thread b¹ formed on same, upon which the carriage E is provided to travel as the
shaft revolves. This shaft is geared at its other end with the driving shaft a³
which is preferably situated above it, and upon which a loose sleeve a bearing the
band pulley F is mounted. Between these two shafts a & a³ the double lever H
is pivoted, the one end being arranged to operate the clutch between the driving
shaft a and the loose sleeve at and the other end f¹ between the screw b¹ for
operating the carriage and the lower shaft a² a band spring being provided to
press against the clutch so as to keep both clutches normally engaged until the
adjustable screw pin e¹ which is mounted upon the carriage E as it travels presses
the clutch out of gear with both the top and bottom shaft a² & a³ &
bottom shaft a³ a pinion K is mounted which gears with a spur M of considerably
increased size and with this spur the drum N is connected to which the catgut n'
for supporting the weight W is attached so that as the machine is in operation for
coiling the length of wire the weight is wound up until the travelling carriage E
disconnects the clutches as before described which disconnects the motion of the
band and pulley sleeve a from the driving shaft a³ thus stopping the machine and
at the same time disconnecting the screw upon which the carriage is travelling
in the one direction which allows the weight W to revolve the spur M and pinion K
in the reverse direction which revolves the screw and brings the carriage back
ready for starting again but by reason of the pressure of the spring h¹ through the
lever H upon the head of the screw e the weight W is not sufficient to cause this
reverse action until the pressure upon the screw is relieved by the operation of
the cam pl by hand. The starting of the machine is effected by the handle P and
cam p' the turning of which by hand throws the clutches into gear. The clutch
may be effected by dog teeth as shown or preferably by friction cones. It will
thus be seen that by the use of the spur K and pinion M the travel of the
weight W for bringing back the carriage is materially reduced which is a
considerable advantage.
