PROVISIONAL SPECIFICATION.
Improvements in Pneumatic Wheels for Carriages and other
Vehicles.
JOHN PHILIPSON Junr. of 27 Pilgrim Street, Newcastle upon Tyne, Carriage
Manufacturer, do hereby declare the nature of this invention to be as follows:-
Prior to the invention of pneumatic wheels patented by Mr. J. C. Hall
No. 3968 of 1891 and No. 7663 of 1892 it has been the practice in constructing
the wheels of carriages bicycles, tricycles and other vehicles, to make the same
with centre hubs or naves, spokes and rims of one or more felloes or parts, and to
surround the same, with suitable tyres.
In carrying out my invention which applies entirely to the hub or axle bush,
flanges and supports, and which is designed to give height and beauty of shape, I
arrange the said flanges and supports with a hole or holes through the centre to
relieve the windage of the pneumatic wheels aforesaid, and to which wheels in
principle I lay no claim, but merely to the metal frame work surrounding the
hub or nave as aforesaid. From the said hub may branch three or more forks or
stays to support or contain two flanges, corrugated or otherwise constructed to give
strength and lightness, meeting in the centre and which are secured together, by
dovetails, hoops, bolts or the like as may be desired forming a cavity, gutter or
channel into which Mr. Castle Hall's air ball or chamber, can be placed. The
framework may also be made in two halves, in cast metal or other material, and
the utility of my invention is the construction of a pneumatic wheel, of extra
height, and with an open centre to relieve windage and having a light and elegant
appearance, for pleasure carriages and other vehicles, indeed all wheeled machines
including household and hospital barrows for moving food and utensils, noiselessly
and without jarring, thay be fitted with wheels made in accordance with my said
invention. The design of these hubs and flanges may be varied in many ways,
for example, the cavities through the said supports may be oval oblong or other
shape, and may be made of any metallic substance, and the bearings may be fitted
with balls, cones or in any other suitable manner.
Dated this 29th June 1893.

COMPLETE SPECIFICATION.
Improvements in Pneumatic Wheels for Carriages and other;
Vehicles.
JOHN PHILIPSON Junr. of 27 Pilgrim Street Newcastle upon Tyne, 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 :-
Prior to the invention of pneumatic wheels by Mr. J. C. Hall No. 3968 of
1891 and No. 7663 of 1892 it has been the practice in constructing the wheels of
carriages bicycles and other vehicles to make the same with centre hubs or naves,
spokes, and rims of one or more felloes, or parts and to surround the same with
suitable tyres.

page_text: In carrying out my invention which applies entirely to the hub or axle bush,
flanges or supports, and which is designed to give height and beauty of shape I
arrange the said flanges and supports with a hole or holes through the centre to
relieve the windage of the pneumatic wheels aforesaid, and to which wheels in
principle I lay no claim but merely to the metal frame work surrounding the hub
or nave as aforesaid.
From the said hub may branch three or more forks or stays to support or contain
two flanges corrugated or otherwise constructed to give strength and lightness,
meeting in the centre and which are secured together by dovetails, hoops, bolts or
the like as may be desired, forming a cavity, gutter or channel into which
Mr. Castle Hall's air ball or chamber can be placed. The frame-work may also
be made in two halves in cast metal or other material and the utility of my invention
is the construction of a pneumatic wheel of extra height and with an open centre
to relieve windage and having a light and elegant appearance for pleasure carriages
and other vehicles, indeed all wheeled machines including household and hospital
barrows for moving food and utensils noiselessly and without jarring, may be
fitted with wheels made in accordance with my said invention.
The design of these hubs and flanges may be varied in many ways for example
the cavities through the said supports may be oval oblong or other shape and
may be made of any metallic substance and the bearings may be fitted with balls,
cones or in any other suitable manner.
In the annexed drawings Fig. 1 represents a plan view and Fig. 2 a part
sectional view of the wheel. BB are the walls of the air chamber, A showing
the interior which is filled with compressed air in any suitable manner. The said
walls may also be composed of rubber and canvas or their equivalents arranged in
the usual way to give an air proof chamber of great strength. CC represent the
flanges which may be made of any suitable, metal and which are in two halves
meeting at the point X Fig. 2. When placed together as shown they form a
trough or cavity for receiving the said air chamber B. DD represent the forks
or stays before mentioned which support or contain the said flanges. E is the hub
or axle bush and G is the cavity through the same and through which I arrange
any suitable spindle or axle and bearings. HHHH illustrate the open centre
cavities which may be of any shape or form according to the number and shape of
the said forks or stays DD.
Having now described and particularly 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 :-
A wheel constructed with an open centre but without the ordinary spokes and
felloes and comprising a circular air chamber carried between two half discs or
flanges, the latter being supported by forks or stays which branch from the hub
or axle bush substantially as described.
Dated this 30th day of March 1894.
