PROVISIONAL SPECIFICATION.
Improvements in or connected with Walking Sticks, Umbrella
Sticks, and the like.
I WILLIAM FREDERICK NORMAN Mottram near Manchester Schoolmaster do
hereby declare the nature of this invention to be as follows:-
This invention has for its object an improvement in walking sticks umbrella
sticks or the like by which a coil spring composed of steel or other suitable
material is connected in such a manner as to propel the pedestrian. The stick
consists of two parts one working within the other with telescope action. The
spring coil is simply placed over the part of the stick working within the other,
and is then fastened to the stick in any suitable manner. I do not claim for the
application of coil spring power to sticks apart from the fact that in this invention
no tubes are used and the coil spring being made to work outside the stick is
capable of being made larger & stronger and is a much simpler and cheaper method
than any employed before.

COMPLETE SPECIFICATION.
Improvements in or connected with Walking Sticks, Umbrella
Sticks, and the like.
I WILLIAM FREDERICK NORMAN Mottram near Manchester Schoolmaster
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 :-
This invention has for its object improvements in walking sticks umbrella sticks
and the like and consists in employing a spiral spring applied to the stick in such
a way as to propel and assist the pedestrian in his efforts of walking.
On the accompanying drawing Fig. 1 is an exterior view and Fig. 2 a transverse
sectional view of so much of a walking stick as is necessary to illustrate my
improvements as applied thereto.
În accordance with my invention the stick is formed in two parts a and b the
upper part a being furnished with a solid or hollow spindle or piston c. working
telescopically within a tubular recess d in the lower part . The lower part is lined
or furnished with a piece of metal tubing e which serves to guide the spindle c and
strengthen the telescopic connection.
Surrounding this telescopic connection and visible from outside is a spiral or
other similar spring the respective ends of which abut against india rubber
washers 9 9 placed against the shoulder formed by the upper portion of the stick
and against the shoulder formed by the end of the lower portion.
The end of the spindle or piston is widened or bulged out to prevent its getting
out of place and to hold the parts together.
It will now be seen that when the stick is brought in contact with the ground
in the ordinary way and the weight of the person carrying the same is more or
less thrown thereon the spring will be compressed but when by the act of
walking and as soon as such weight is removed the spring will be released and so
serve as a propellant and help the pedestrian forward.

page_text: Having thus particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I wish it to be understood
that I am well aware that a spiral spring concealed in the length of the stick has
already been used for the purpose hereinbefore specified and therefore I make no
claim to such an arrangement but what I do claim is :-
-
The employment of a spiral or other similar spring fitted to a walking stick,
umbrella stick or other like article and visible from the outside in conjunction with
a telescopic connection mounted and operating substantially as and for the purposes
herein before described and illustrated on the accompanying drawing.
