PROVISIONAL SPECIFICATION.
Improvements in Railway and Tramway Vehicles.
I Sir EDWARD GREEN, Baronet of Wakefield, in the County of York,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to improved means and appliances for supporting the
bodies of railway and other carriages on their underframes to subdue noise, reduce
oscillations and give increased comfort to the travelling public.
To carry my invention into practice I prepare a series of inflatable rings or
lengths of tubes with closed ends and protect or cover these with a separate fabric
or with coated fabrics or incorporated with the rubber to prevent a too great
inflation. These I arrange in any desired number or positions on the underframe
of a railway carriage and set the body on so that it shall be supported by them,
suitable guides or chocks being employed to locate and retain the inflated rings or
tubes in their respective positions.
The material of the inflatable rings or tubes can be of any desired thickness and
strength to resist undue compression from the superincumbent weight and constitute
a series of cushions between the under frame and the body of the vehicle.
Each ring or tube will be provided with a charging and self closing nozzle and
air can be furnished if so desired in a similar manner to that of the air brakes of a
train direct from an engine, or by a hand pneumatic pump.

I, Sir EDWARD GREEN, Baronet, of Wakefield, in the County of York,
Engineer, 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 improvements in railway and tramway vehicles.
To carry my invention into practice, I prepare a series of inflatable rings, or
lengths of tubes with closed ends, and protect or cover these with a separate fabric,
or with coated fabrics, or incorporated with the rubber to prevent a too great
inflation. These I arrange in any desired number or positions on the under frame
of a railway carriage, and set the body on so that it shall be supported by them,
suitable guides or chocks being employed to locate and retain the inflated rings or
tubes in their respective positions.
The material of the inflatable rings or tubes can be of any desired thickness
and strength to resist undue compression from the superincumbent weight
and constitute a series of cushions between the under frame and the body of the
vehicle.

page_text: Each ring or tube will be provided with a charging and self closing nozzle, and
air can be furnished if so desired in a similar manner to that of the air brakes of a
train direct from an engine, or by a hand pneumatic pump.
My invention will be clearly understood by reference to the annexed drawings.

in position at intervals for the body of the carriage to rest upon.

All the letters of reference apply to like parts in all the figures.
A inflated bag of the shape desired to suit the position it has to occupy.
B, B, half cup or dished sockets, within which the bag is held. C brackets affixed
to the under frame D of the vehicle, and E brackets secured to bottom rail F of
body G. H, H, are bolts projecting from brackets E to pass down through the
brackets C and for locating the body to prevent it having other than an up and
down motion while travelling.
I nozzle of bag A. J air tube in connection with any kind of pump and either
fed singly by separate tubes, or any number of such tubes may be coupled up as
desired.
In Figures 1 and 2 I show a vehicle having rotating axles K but, as seen
at Figures 5 and 6, the axle may be a fixture to the bracket C by clip plate M and
pinch nuts N in which case the bolts H can project upwardly from the bracket C
and up through the bracket E.
The inflated bags A may be of any degree of thickness in so far as the material
of which they are made is concerned, but I prefer that they be of thin rubber and
enclosed in a compounded rubber and canvas jacket A¹, as represented in the
sectional views, and when ring shaped bags A are used, as in the views Figures 8, 9,
10, and 11, I purpose making the jackets of disc form and clipping their edges into
close contact by ring plates P, P, and screws Q, Q, said jackets being flexible and
kept extended by air pressure within the bag A.
At most of the figures shown on the annexed drawings, each bag by its nozzle is
supposed to be inflated separately but they may be simultaneously inflated by
connecting their branch tube to a main supply R from a powerful hand pump, or
from some moving part of the vehicle to which my system is fitted. This can
readily be accomplished by providing a pump reservoir with a safety or blow off
valve which shall open when the necessary expansion or inflation of all the bags
have taken place, the non-return valves in the nozzles of the air bags being
sufficient to retain the inflated charges in the bags, or the inflation may be effected
from a pump on the engine in a similar manner to that adopted on most railways
for working the vacuum brakes, or the air pressure brakes.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The arrangement of appliances affixable to a vehicle of the kind mentioned to
enable the body to be supported upon air inflated bags whether the inflation be
effected by hand or by power as hereinbefore described and exemplified by the

page_text: 2. Fixing cup shaped or dished brackets on or to the under frame and body frame
respectively of a vehicle for the reception and location of one or more air inflation
bags on which the upper or body can rest and be supported substantially in the
manner represented and for the purpose described.
