Improvements in the Method of and in Apparatus for Constructing
Spherical Balloons and other Forms of Gas or Air Bags of Shapes
known as Solids of Revolution.
1 HOWARD LANE, of 115 Palmerston Buildings, Old Broad Street, in the City of
London Engineer, do hereby declare the nature of my said invention to be as
follows:-
The object of my invention is to effect improvements in the manufacture of balloons
and other gas and air bags and containers.
I construct a roller or spindle with tapering or otherwise shaped extremities, bearing
at each point of its length, a geometrical proportion to a corresponding point or
diameter of the balloon or gas bag to be constructed. The roller or spindle is supported
on anti-friction wheels. The skins or laminæ, or substances of which the balloon is
constructed are spread over the surface of the roller or spindle the latter being rotated
on its longitudinal axis as the material is added. The fabric is then detached from the
roller or spindle, and held in reserve until it has made sufficient revolutions to
complete the amount of fabric required, the two extremities of the fabric are then
joined together.

I HOWARD LANE, of 115 Palmerston Buildings, Old Broad Street, in the City of
London, Engineer, do hereby declare the nature of my said invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
The object of my invention is to effect improvements in the manufacture of balloons
and other gas and air bags or containers.
I construct a roller or spindle with tapering or otherwise shaped extremities, bearing,
at each point of its length, a diameter proportional to a corresponding diameter of the
balloon or gas bag to be constructed. The roller or spindle is supported on anti-friction
wheels.
The skins or laminæ, or substances of which the balloon is constructed, are spread
over and fitted or adapted to the surface of the roller or spindle and pieced together,
the latter being rotated on its longitudinal axis, as the material is added. The fabric
is then detached from the roller or spindle, and held in reserve until the spindle, with
the fabric upon it, has made sufficient revolutions to complete the amount of fabric
required.
The two extremities of the fabric are then joined together.
And in order that my said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.
Fig. 1 is a longitudinal elevation of the spindle & Fig. 2 is a section of the same,
shewing the material in process of making up.
a is the spindle, mounted upon rollers bb. cc is the material, which is passed on
to and taken from the spindle, as shown by the arrows.
The material is made up and graduated so as to adapt itself to the varying diameters
of the spindle, and, when sufficient material has been made up, the balloon is finished
with one principal join.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The method of obtaining the exact shape and configuration of the material for
constructing spherical balloons, and other forms of gas or air bags, by means of
suitable spindles which form solids of revolution proportional to the forms required,
substantially as hereinbefore described and illustrated by the drawings.
