page_text: 1, JAMES WALTER STANSFIELD, Contractor, of Wellington Terrace, Todmorden,
Yorkshire, do hereby declare the nature of this invention to be as follows:-
This invention relates to certain detail improvements applicable to the invention
described in the Specification of a former Patent granted to myself and another,
dated 27th February 1888, No. 2926, and constituting an alternative method of
obtaining the spiral ascension of the apparatus.
According to the present invention, l'arrange a worm to slide up and down a
revolving shaft going from top to bottom of an upright post. The worm has a key.
cast solid to it which fits loosely into a key way in the shaft and revolves with it,
but the thread on the worm being set to gear with the bevel teeth formed on a
rack, causes the worm in trying to revolve with the shaft to rise, or slide upwards
or downwards according to the direction in which the shaft revolves.
To a loose collar at top and bottom of the worm is fixed an arm carrying a
plate which surrounds the upright post. This plate is caused to revolve in
ascending or descending by a small cog wheel set to run in connection with the
worm. The circular plate mentioned is to form the floor of a balloon car, over
which and surrounding the post is fixed a balloon distended by compressed air.
The balloon is allowed to slide up and down the post by there being through its
centre a strong oiled canvas tube with a ring at top and small rollers fitted to it
to permit free motion.
I, JAMES WALTER STANSFIELD, Contractor, of Wellington Terrace, Todmorden,
Yorkshire, 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 relates to certain detail improvements applicable to the inven
tion described in the Specification of a former Patent granted to myself and
another, dated 27th February 1888, No. 2926, and constituting an alternative
method of obtaining the spiral ascension of the apparatus.
According to the present invention, which I show on the annexed drawings,
Figures 1, 2, 3 and 4, I arrange a worm A to slide up and down a revolving

two or more shafts. The worm A has a key cast solid to it which fits loosely

page_text: into a key way in the shaft B and revolves with it, but the thread on the worm
being set to gear with teeth D formed on a rack fixed to the upright post C
causes the worm A in trying to revolve with the shaft B to rise, or slide upwards
or downwards according to the direction in which the shaft B revolves.
A loose collar E has arms F, F, carrying a plate G (or the arms may have
pullies at extremities) surrounding the upright post C and shaft B as a track
and carrying a platform H. which is revolved in ascending or descending by
means of a small cog wheel I set to run in connection with the wormi A. The
platform forms the floor of a balloon car, over which and surrounding the
post C and shaft B is fixed a balloon K distended by compressed air or otherwise.
The balloon K is allowed to slide up and down the post C whilst revolving with
platform by there being through its centre a strong oiled canvas tube. L fastened
to suitable framing guided by a ring at top and small rollers te permit free motion.
The worm A at top and bottom abuts against the plate G and the collar E to
keep it in position.
Ordinary coal gas can be employed in the balloon in sufficient quantity to
equilibriate said balloon and its attachments, the weight of the occupants of
the car being borne by the worm A and rack D.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is:-
The apparatus shown on the annexed drawings and comprising an imitation
balloon operated by worm and rack and with gear for ascending and descending
spiral motion around a vertical post, as set forth.
