Improvements in Machinery or Apparatus Used for Forming Wire
into Coils or Spirals for Use in the Formation of Mattresses and
for other similar Purposes.
I GEORGE BIRCH trading as G. Birch and Co. of Islington Tool Works, Islington
Grove, Salford in the county of Lancaster. Engineer, 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:-
My invention relates to machinery or apparatus used for forming wire into coils
or spirals for use in the formation of mattresses and for other similar purposes.
In the accompanying drawing Fig. 1 is a side elevation partly in section, Fig. 2 a
plan and Fig. 3 an end view showing so much of a machine or apparatus for forming
coils or spirals of wire for forming mattresses or for other similar purposes as is
requisite to illustrate my invention. The same letters of reference are applied to
corresponding parts in all of the figures.
The first part of my invention consists in arrangements for pressing together the
discs or rollers a, b between which. passes the wire to be coiled or made
into spirals.
c is an arm formed or provided with a stud d passing through and capable of being
turned in a hole formed in the end e¹ of the headstock e. Secured to the arm c by a
nut fit a stud f upon which and free to be rotated thereon is the disc or roller b.
Projecting from the end e¹ of the headstock e is a bracket g through a hole in which
passes a rod on the lower end of which is formed a hook . The upper end of
the rod is provided with screw-threads provided with a winged nut 2. jis
a spring one end of which is secured to the hook while the other end
of such spring is secured to an eye c¹ fast with the arm c. The spring j
by tending to turn the arm c in the direction indicated by the arrow A causes
the disc or roller to be pressed towards the disc or roller a, and ensures that
the discs or rollers a, b, shall draw forward the wire passing between them. By the
nut being turned in one direction or the other the discs or rollers a, b may be caused
to press with greater or less force upon the wire passing between such discs
or rollers.
A further part of my invention consists in arrangements by means of which I am
enabled to quickly stop when required the rotation of the discs or rollers a, b. between
which the wire to be coiled or formed into spirals passes in machinery or apparatus
used for forming coils or spirals of wire used in the formation of wire mattresses and
for other similar purposes.
k is the spindle upon one end of which is mounted the disc or roller, a. Mounted
upon the spindle and free at times to be turned thereon is a pulley m. The pulley m
is prevented from being moved longitudinally upon the spindle k by means of the
collars & secured to the spindle k. Mounted upon the spindle and free to be moved
longitudinally thereon is a disc or plate l. The disc or plate 7 is prevented from:
turning upon the spindle k by means of a key k² fast upon the spindle k which passes
into a groove formed in the disc or plate l. Around the circumference of the disc
or plate is formed a conical surface 12 which at times may be forced against a conical
surface m¹ formed upon one side of the pulley m. Projecting from the end e² of
the headstock e is a bracket e³ to which is secured a stud et mounted upon which
and free to be turned thereon is a lever n one end of which is formed with a fork n'
which passes into a groove l³ formed around a boss formed on the disc or plate l.
One end of the lever n is formed as a handle. Secured to the end of the
headstock e by set screws is a curved bracket o to which is secured by means of
screws a curved strip o' of wood or other suitable material. The surface o of the

page_text: strip of of wood or other suitable material is formed conical and formed of an angle
to correspond with the conical surface ³ formed upon the disc or plate 1. The pulley m
receives inotion by means of a strap-in any convenient manner.
When the spindle k is to be rotated the lever n is turned in the direction indicated
by the arrow B and by being so turned will cause the disc or plate to be slidden in
the direction indicated by the arrow Cand so move the conical surface 12 against the
conical surface m¹ formed on the pulley m. Rotary motion will then be transmitted
from the pulley m to the disc or plate and spindle k, the disc or plate l and the
conical surface m on the pulley m together forming a "friction clutch." When it is
desired to stop the rotation of the spindle k the lever n is turned in a direction
opposite to that indicated by the arrow B and will by being so turned cause the disc
or plate to be slidden upon the spindle k in a direction opposite to that indicated by
the arrow c and remove the conical surface away from the conical surface m¹. A
further movement of the disc or plate in the direction opposite to that indicated by
the arrow C will cause the conical surface 13 upon the disc or plate l to be brought against
the conical surface o² of the strip of of wood or other suitable material which surface o²
acting as a brake will stop the rotation of the disc or plate and spindle k. Although
I have only shown the conical surface o as being a portion of a circle the said
conical surface o² may be made an entire circle if required. By bringing the conical
surface against the conical surface o² I am enabled to quickly stop the rotation of
the spindle and am thus enabled to prevent the waste of wire and loss of time
hitherto caused by the spindle k continuing to rotate after the conical surface 12 of the
dise or plate has been withdrawn from the conical surface m¹ of the driving
pulley m.
Instead of the conical surface or brake o' a fixed brake or surface of any other
suitable form may be employed, a surface being formed upon the disc or plate / to
correspond with the said fixed brake or surface as does the conical surface with the
conical surface o².
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In a machine or apparatus for forming wire into coils or spirals to be used for
making mattresses or for other similar purposes, the hereinbefore described
arrangements for pressing together the dises or rollers between which passes the wire
to be coiled or made into spirals, which arrangements consist in the arm c, spring j,
rod and nut ² all employed, arranged and operating substantially as hereinbefore
described in reference to and indicated in and by the accompanying drawing.
2. In a machine or apparatus for forming wire into coils or spirals to be used for
making mattresses or for other similar purposes the herein before described arrangement
by means of which the discs or rollers between which passes the wire to the coiled or
made into spirals. are enabled to be quickly stopped, which arrangement consists in a
stationary surface or brake employed and arranged substantially as hereinbefore
described in reference to and indicated in and by the accompanying drawing.
