Improvements in or relating to Pneumatic Rocking Chairs and the
like and in Apparatus therefor.
I, HENRY JOHNSON, of 4, Vernon Street, Bolton, in the County of Lancaster,
Engineer, (a communication from Thomas Henry Johnson of Petersburg Side,
27, Skirokija Street, St. Petersburg, Russia), do hereby declare the nature of
my said invention to be as follows:-
This invention refers to improvements in or relating to pneumatic rocking
chairs and the like and in apparatus therefor and consists in securing in any
convenient manner to the underside of each rocker of a chair a pneumatic tube.
Each rocker of a chair is fitted with a valve and connections to allow of each
pneumatic tube being inflated by means of a pump. This invention is also
applicable for rocking horses, cradles, and other analogous articles.

Improvements in or relating to Pneumatic Rocking Chairs and the
like and in Apparatus therefor.
I, HENRY JOHNSON, of 4, Vernon Street, Bolton, in the County of Lancaster,
Engineer, (a communication from Thomas Henry Johnson of Petersburg Side,
27, Skirokija Street, St. Petersburg, Russia), do hereby declare the nature of
my said invention and in what manner the same is to be performed, to be parti-
cularly described and ascertained in and by the following statement:.
-
This invention refers to improvements in or relating to pneumatic rocking
chairs and the like and in apparatus therefor and consists in securing in any
convenient manner to the underside of each rocker of a chair a pneumatic tube.
Each rocker of a chair is fitted with a valve and connections to allow of each
pneumatic tube being inflated by means of a pump. This invention is also
applicable for rocking horses, cradles, and other analogous articles.
DESCRIPTION OF DRAWINGS

page_text: In all, the figures the same letters are employed to indicate corresponding
parts.
E represents a rocking chair; G the rockers; H pneumatic tube; I valve,
and Winflating bag inside pneumatic tube H.
To the underside of each rocker G of the rocking chair A is secured the metallic
plate or seat J by means of the screws K or otherwise; the metallic plates or
seats J being provided with the angular projections L to receive the angular
sides M of the pneumatic tube H consisting of india-rubber and canvas combined,
and by which it is secured in position on the underside of the rockers G when
inflated. The ends Z of the pneumatic tubes H are closed to prevent the escape
of air or other inflating medium. The outside pneumatic tube H is composed of
india-rubber and canvas as employed in cycles, and the inside tube or inflating
bag W is composed of india-rubber as employed in cycles. The pneumatic tube H
is slit at V to allow the same to securely fix itself against the angular projec-
tions L when inflated. The pneumatic tyre may be made in precisely the same
manner as any pneumatic cycle tyre with the exception that the ends Z are
made closed to form a section of a circle instead of a whole ring or circle. The
metallic plate or seat J may also be made on the same principle as a cycle tyre
or rim with the exception that it is a section of a circle instead of a whole rim
or circle with the ends made so as to hold. the ends of the pneumatic tube H
as well as the sides. The pneumatic tube H is fitted to each rocker G and is
provided with the outer valve casing () secured thereto by the nut P mounted
on the screwed end Q of the stem of the valve casing 0. The screwed end Q
of the stem of the valve casing 0 is fitted with the nut R for holding the valve
casing S in the outer valve casing 0. The upper end of the valve casing S is
fitted with the screwed caps T to seal or close the same after inflation has been
performed.
When it is desired to inflate the pneumatic tube, I it is effected by removing
the screwed cap T from the upper end of the valve casing S and applying thereto
an air pump in precisely the same manner as when inflating the pneumatic
tyres of cycles. This invention is also applicable for rocking horses, cradles,
and other analogous articles, such as, foot-stools.
An important feature of this invention is that it renders the action of rocking
chairs, cradles, and the like perfectly noiseless when in use; and also reduces
the wear and tear of carpets, parquet, and other floors and coverings to a
minimum when employed thereon.
I would have it understood that I do not claim the style or make of valve
shown and described as any ordinary pneumatic valve now in use may be employed.
Having now particularly described and ascertained the nature of my said-in-
vention and in what manner the same is to be performed, I declare that what
I claim is:-
The general arrangement construction and combination of parts composing
the improvements in or relating to pneumatic rocking chairs and the 'like and
in apparatus therefor consisting of the plates or seats J secured to the rockers G
and provided with the angular projections L to receive the angular sides M. of
the pneumatic tubes H with the solid or closed ends Z, and by which they are
secured in position on the underside of the rockers G when inflated, the whole
being applied, arranged, and operating substantially as described and as illus-
trated in the annexed drawings.
