3. A Victorian Folklore Legend
Have you ever wondered what kind
of spring Tigger would need to
bounce as high as he does? Or just
what the minimum requirements
are for Inspector Gadget’s spring-loaded
boots? How about the old
English beast Spring-heeled Jack,
who, according to the myth, stalked
the streets of Victorian London?
With Halloween on our minds,
we’ve decided to look at that old
Victorian folklore legend.

4. Who was Spring-heeled Jack?
So, who was Spring-heeled Jack?
He was first sighted in London,
1837. His grip was described as
‘cold and clammy as those of a
corpse.’ Spring-heeled Jack leapt
over a 9ft wall, shrieking and
giggling. Legend has it that he can
effortlessly jump on top of houses,
dancing on the rooftops and
vanishing into the night. The last
time he made his terrifying
presence known was in 2012. So
watch out this Halloween…

5. How did he do it?
But the real question is, how the
devil did this devil manage to
leap so high? What type of
equipment would he need to
vanish so swiftly? As engineering
specialists and amateur
paranormal investigators – for
this Halloween, at least – we
thought we’d take a gander at
this mystery.

6. Extensions Springs
Extension springs are loaded in
tension and designed with loops
or hooks at either end. When
force is applied, the spring
attempts to bring the two ends
back together. Pretty handy for
lever mechanisms and doors, but
not so much if you’re looking to
bound as high as houses. Even
the large extension springs we
manufacture aren’t going to cut it
for the spring-heeled terror.

7. Torsion Springs
We produce high-quality torsion
springs – but are they perfect for
springing 9ft in the air? Torsion
springs feature a coiled spring with
two legs at either end. When the
legs are pushed down, the spring
naturally resists. You’ll find our
designs in hinges, lever return
applications and counterbalances.
But unless Jack’s wants to
straighten up upon landing torsion
springs aren’t for him.

8. Compression Springs
Compression springs are probably
the most common spring
configuration you’ll find. When
pressure is applied to the spring, it
pushes back against the load in
order to reform to its usual shape.
And while they’re used on things
like door locks and electrical
switches, they could – if you’re
Spring-heeled Jack, at least – be
placed in your boots in order to
reach some truly dizzying heights.

9. The specialists have spoken
If Spring-heeled Jack wants to
bound as high as he can,
compression springs will do the
job. And there are tons of shapes
this Halloween hell-hound can
choose from, from conical and
barrel to hourglass or the traditional
cylindrical designs. And, although
no demonic entity has ever asked
us to create springs for heels, we
can create springs to suit any
specific requirement.

seriously. Using computer
simulations and the latest CNC
machines, coupled with
traditional methods, we can
