Improvements in Apparatus Employed in the Manufacture of Woven
Wire Fabrics, such as are used for Mattress Surfaces and for
other Purposes.
We ISAAC CHORLTON of 19 Blackfriars Street, Manchester, in the County of
Lancaster, Spring Mattress Manufacturer, and GEORGE LAMB SCOTT of the same
place, Engineer, do hereby declare the nature of this Invention to be as follows:-
Our said Invention relates to the apparatus now in use for forming and inserting
the successive coils of wire which compose the fabrics at present generally used for
certain types of mattress surfaces and for other purposes. Our invention consists in
improvements in the general arrangement and construction of the apparatus whereby
it is considerably simplified and the weight and cost of the machine correspondingly
reduced while its speed and work producing power is increased. The improvements
also consist in rendering the wire feeding discs self adjusting to any gauge of the
wire employed, in simplifying the means for holding them in contact; and in bringing
the said wire feeding discs inside of their driving gear so as to bring the nipping
pressure on the wire as close to the holding down bolt as possible so as to diminish the
canting leverage on the self adjusting stud. The whole of the parts of our improved
apparatus are supported or carried by one simple bracket or frame which can be
secured to a table or bench. In front of the bracket are the two wire feeding discs
arranged one above another and which are brought as close to the bracket as possible,
and on the outside faces of the discs are attached or formed gear wheels or teeth which
engage with each other so that the under disc drives the upper. The under disc is
fixed on a shaft which extends to the back of the supporting bracket and carries at its
inner end a toothed pinion which engages with a larger spur wheel on a stud which
projects from the back of the supporting bracket. On the same stud is a fly wheel
which is provided with a handle for driving purposes whereby the spur wheel is driven
and consequently imparts motion to the smaller pinion and its shaft at an increased
speed the said increased speed being communicated to the wire feeding discs in the
manner set forth. The upper wire feeding disc rotates on a stud which projects from
a block carried on the front of the supporting bracket. The said block is loose and
separate from the supporting bracket, and fits into a stepped recess formed therein for
its reception. Through the centre of the block we form a hole to receive a stud which
projects upward from the centre of the stepped recess.. At the foot of the stud we
place an elastic washer, pad, bed or abutment which is preferably made of vulcanised
rubber or other suitably yielding and elastic material or medium or metallic springs
might be used. When the block is slipped upon the stud into its place in the stepped
recess it rests upon this elastic washer or foundation. The top of the stud is screwed
to receive a nut and between this nut and a metallic washer and the top of the block
we interpose a washer or pad of rubber or other resilient material similar to the elastic
pad beneath, so that when the nut is screwed down the block is held between two
elastic pads. A steady pin, feather and groove or other means are used to keep the
block from turning. The wire feeding discs are formed with grooves which nip the
wire and push it forward through the coiling matrix which latter is no part of our
invention. The elastic bedding of the block which carries the upper disc enables the
said upper disc to yield easily to any inequalities in the wire and to adjust itself
automatically to different sizes of wire without giving any trouble to the operator.
In some cases we might dispense with gearing the two wire feeding discs together
and let them rotate each other by frictional contact. The aforesaid improved apparatus
might be driven by power instead of by hand. For example we might fix or form a
frictional ring on the fly wheel and have a sliding frictional clutch on the flywheel

page_text: shaft or stud so that when the clutch halves were moved into or out of contact by a
lever or treadle the machine might be started or stopped and in combination with this
clutch arrangement we might arrange the brake on the reel from which the wire is
drawn so that the said brake would be applied or withdrawn simultaneously with the
stopping or starting of the machine.
Instead of having the frictional clutch applied to the machine itself it might be
fitted to the main driving shaft, a driving belt or chain extending from the driving
half of the clutch to the flywheel or to a pulley on the stud or shaft carrying the
driving spur wheel.

COMPLETE SPECIFICATION.
Improvements in Apparatus Employed in the Manufacture of Woven
Wire Fabrics, such as are used for Mattress Surfaces and for
other Purposes.
We ISAAC CHORLTON of 19 Blackfriars Street, Manchester in the County of
Lancaster Spring Mattress Manufacturer and GEORGE LAMB SCOTT of the same
place 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 and accompanying drawings:
:-
Our said Invention relates to the apparatus now in use for forming and inserting
the successive coils of wire which compose the fabrics at present generally used for
certain types of mattress surfaces and for other purposes. The present invention
consists in improvements in the general arrangement and construction of the apparatus
whereby it is considerably simplified and the weight and cost of the machine corre-
spondingly reduced while its speed and work producing power is increased. The
improvements also consist in rendering the wire feeding discs self adjusting to any
gauge of the wire employed, in simplifying the means for holding them in contact and in
bringing the said wire feeding discs inside of their driving gear so as to bring the
nipping pressure on the wire as close to the holding down bolt as possible so as to
diminish the canting leverage on the self adjusting stud.
To render our said invention perfectly clear we will now proceed more particularly
to describe the same with reference to the annexed sheet of illustrative drawings.
Fig. 1 of the said drawings is a side elevation partly in section of our improved
apparatus.
Fig. 2 is a front view of the apparatus.
The whole of the parts of our improved apparatus are supported or carried by one
simple bracket or frame a which can be secured to a table or bench by bolts or screws
passing through the snugs b. In front of the bracket a are the two wire feeding
discs c and d arranged one above another and which are brought as close to the
bracket a as possible, and on the outside faces of the discs c d are attached or formed
gear wheels or tooth peripheries e. f which engage with each other so that the under
disc d drives the upper c. The under disc d is fixed on a shaft g which extends to the
back of the supporting bracket a and carries at its inner end a toothed pinion h which
engages with a larger spur wheel i and stud ; which projects from the back of the
supporting bracket a and is fixed therein by a pin k. On the same stud j is a fly-wheel
which is provided with a handle for driving purposes whereby the spur wheel i is driven
and consequently imparts motion to the smaller pinion and its shaft g at an increased
speed the said increased speed being communicated to the wire feeding discs c d in the
manner set forth. The upper wire feeding disc c rotates on à stud m which projects
from a block n carried on the front of the supporting bracket a. The said block n is
loose and separate from the supporting bracket a and fits into a stepped space formed
for its reception in the front of the bracket. Through the centre of the block n we

page_text: g
form a hole to receive a stud o which projects upwards from the centre of the stepped
space and passes through the stud m. At the foot of the stud o we place an elastic
washer pad, bed or abutment p which is or might be made of vulcanised rubber or
other suitably yielding and elastic material or medium or a metallic spring or springs
might be used. When the block n is slipped upon the stud o into its place in
the stepped space it rests upon this elastic washer or foundation p. The top of
the stud o is screwed to receive a nut q and between this nut and a metallic
washer and the top of the block n we interpose a washer or pad r of rubber or
other resilient material similar to the elastic pad beneath, so that when the nut
is screwed down, the block n is held between two elastic pads, a steady pin s or
it might be a feather and groove or other means being used to keep the block n
from turning. The wire feeding discs c, d are formed with grooves as shown
which nip the wire and push it forward through the coiling inatrix which does
not appear in the drawing and which is no part of our invention. The elastic
bedding of the block n which carries the upper disc c enables the said upper disc
to yield easily to any inequalities in the wire and to adjust itself automatically to
different sizes or gauges of wire without giving any trouble to the operator. In
some cases we might dispense with gearing the two wire feeding discs together
and let them rotate each other by frictional contact.
The aforesaid improved apparatus might be driven by power instead of by hand.
For example we might fix or form an ordinary frictional ring on the fly wheel
and have a sliding frictional clutch on the flywheel shaft or stud so that when
the clutch halves were moved into or out of contact by a lever or treadle the
machine might be started or stopped and in combination with this clutch arrange-
ment we might arrange the usual brake on the reel from which the wire is drawn
so that the said brake would be applied or withdrawn simultaneously with the
stopping or starting of the machine.
Instead of having the frictional clutch applied to the machine itself it might be
fitted to the main driving shaft, a driving belt or chain extending from the driving
half of the clutch to the flywheel or to a pulley on the stud or shaft carrying the
driving spur wheel.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed we declare that what, we
claim is.
1. The general arrangement construction and combination of parts comprising
the improved apparatus for feeding wire in the operation of manufacturing or
weaving metallic mattresses substantially as described.
2. In apparatus of the indicated nature, placing the wire feeding discs next to
the supporting bracket or frame and on the inner side of the driving gear or
teeth which connect the said feeding discs so as to decrease the distance between
the wire nip of the feeding discs and the stud carrying the elastically supported
block substantially as described and shown.
3. In apparatus of the indicated nature the employment of a block such as the
block n, carrying the stud upon which one of the wire nipping and feeding discs
revolve and connected to the bracket or frame by a central stud and steady pin
or other means, the said block being held between elastic pads, beds or washers
so as to enable the block and consequently the lise to yield automatically to
irregularities in the wire and enabling the apparatus to be used for different
gauges of wire without specific setting substantially as described and shown.
