I THOMAS HOUSLEY of Edward Street, Glossop, in the County of Derby,
Engineer and Machinist, do hereby declare the nature of said invention for
"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR IMPARTING A SPIRAL FORM
TO METALLIC WIRE FOR USE IN THE MANUFACTURE OF METALLIC
PILLOWS CUSHIONS RAILWAY SEATS AND OTHER PURPOSES" to be as follows:-
MATTRESSES
According to this invention I employ a stand or support on the top of which are
suitable bearings for a shaft, which I will call the main or driving shaft. On one
end or portion of this main or driving shaft, there are provided a loose pulley and
a friction pulley, and a lever and spring, to allow of the machine being thrown in
and out of gear when desired. On the same shaft there is also provided a suitable
hand-wheel. On the other end or portion of the main or driving shaft there is a
wheel, one part of the circumference of which is provided with teeth whilst the
adjacent part is provided with a groove extending round the wheel. A similar
toothed wheel with a like groove is fitted on a counter shaft directly above the
main or driving shaft. This second toothed wheel gears into the first wheel, and
the metallic wire to be coiled is subjected to the action of being forced by them
through a chamber or cylinder in the interior of which there is a spiral or other
suitably shaped spindle. All the sockets and supports may be adjusted or set in
split bearings or holders by means of screws or bolts.

Engineer and Machinist, 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:-
According to this invention I employ a stand or support on the top of which are
suitable bearings for a shaft, which I will call the main or driving shaft.
On one end or portion of this main or driving shaft, there are provided a loose
pulley and a friction pulley, and a lever and spring to allow of the machine being
thrown in and out of gear when desired. On the same shaft there is also provided
a suitable hand-wheel. On the other end or portion of the main or driving shaft
there is a wheel, one part of the circumference of which is provided with teeth
whilst the adjacent part is provided with a groove extending round the wheel.
A similar toothed wheel with a like groove is fitted on a counter shaft directly
above the main or driving shaft.
This second toothed wheel gears into the first wheel, and the metallic wire to be
coiled is subjected to the action of being forced by them through a chamber or
cylinder in the interior of which there is a spiral or suitably shaped spindle. All
the sockets and supports may be adjusted or set in split bearings or holders by
means of screws or bolts.
In the accompanying sheet of illustrative drawings Fig. 1 is an end view, Fig. 2
a side view and Fig. 3 a plan or top view of a machine or apparatus according to
my invention. Fig. 4 is a detached detail view.
The stand 1 carries a shaft 3 running in bearings 2. Upon the shaft is a loose
belt pulley 5, and a disc 4, the latter secured to the shaft. Upon the boss of the
pulley 5 is a grooved collar 11 which is engaged by a pair of rollers on the fork 10.
This fork, together with the hand lever 6 by which it is operated, is pivotted on the
vertical spindle 8, and is normally drawn in one direction by the spring 12. By
means of the hand lever the loose pulley 5 can be forced into frictional contact with
the disc 4, and the machine be thus put in motion. The shaft can also be rotated
by the hand wheel 13.
Upon the opposite end of this shaft there is a toothed wheel 14 which gears
with a similar wheel 15 on the countershaft 16. In addition to the toothed
portion each of these wheels has a plain ring provided with two grooves. These
grooved rings serve as feed rollers to force the wire into the die 18.
One groove
only on each wheel is used at a time.
17 is a socket or tube through which the metallic wire intended to have a spiral
form imparted to it, is fed. 17* is a second socket or tube through which the wire

page_text: is conducted to a chamber or cylinder 18. This chamber or cylinder is fitted with
a spindle 19 provided upon one portion of its length with a spiral groove or recess,
the particular shape of which depends upon the form it is desired to impart to the
metallic wire. The chamber or cylinder 18 is carried by a socket piece 20
supported in a split bearing or holder 21 which is itself carried in a similar bearing
or bolder 22 secured to the stand or support 1. By this arrangement the socket
piece 20 and holder 21 may be readily adjusted by loosening the screws 23 to place
the chamber or cylinder 18 in any desired horizontal position. The action of the
machine is to force by means of the grooved portions of the wheels 14 and 15 the
metallic wire through the chamber or cylinder and through the groove or recess of
the spindle 19 placed therein, and thus to impart a spiral form to such wire and fit
it for use in the manufacture of metallic matresses, pillows, cushions, railway seats
and other purposes.
Figs. 5 6 and 7 shew a modification in which a spiral 19 is used in the cylinder
or chamber 18 in lieu of the spirally grooved spindle.
Having now particularly described and ascertained the nature of iny said
invention, and in what manner the same is to be performed, I declare that what
I claim in machinery or apparatus for imparting a spiral form to metallic wire for
use in the manufacture of inetallic mattresses, pillows, cushions, railway seats and
other purposes, is
1. The use of a chamber or cylinder and a spirally grooved spindle or its
equivalent so arranged that wire fed into the said chamber or cylinder, emerges in
a spiral form, substantially as described.
2. The use in combination with a chamber or cylinder and spirally grooved
spindle or its equivalent of a pair of feed rollers for forcing the wire forwards,
substantially as described.
3. Machinery or apparatus, constructed, arranged and operating substantially as
described with reference to and shewn in the drawings for the purpose specified.
