Improvements in Means for Reducing or Preventing Vibration in
Wheeled Vehicles.
I, HENRY WALLACE DOVETON DUNLOP, of Viewmount, Lucan, in the County
of Dublin, Ireland, Civil 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 means for reducing or preventing
vibration in wheeled vehicles, and has reference more particularly to means of
the kind or class in which the body of the vehicle is supported on one or more
inflated tubes, interposed between the said body and the under frame of the
vehicle.
According to this invention the inflated tube or each such tube rests in solid
blocks of rubber or other suitable material secured to the under frame of the
vehicle while the body of the vehicle has secured to it corresponding blocks which
rest on the tube immediately above the first mentioned blocks.
The blocks have cemented to them short flexible strips which are fastened
around the inflated tube and serve both to provide a positive connection between
the vehicle body and the under frame, to protect the tube from undue wear and
also to enable the position of the blocks on the tubes to be occasionally altered.
The said blocks may however be themselves cemented to the tubes in some cases.
In order that the invention may be clearly understood and readily carried into
effect I will proceed to describe one arrangement in accordance therewith, by aid
of the accompanying drawings wherein
Figure 1 is a plan of the under frame of the vehicle with the inflated tube in
position.
Figure 2 is a sectional view to a larger scale showing the arrangement of the
rubber blocks above and below the inflated tube.
Figure 3 is a detail view showing the arrangement for fastening the strips above
referred to.
A is the underframe of the vehicle, and B is the body thereof.
a is the inflated tube which rests at the four points a¹ on the members of the
underframe. This tube may be circular as shown or of other convenient form.
bb are the blocks secured to the under frame. These blocks are provided
with a broad base b¹ which is secured to the under frame by clips or collars b
while their upper part b³ has a recess or cavity for the tube to rest in.
cc are the rubber blocks which are secured to the body B of the vehicle by
clips or collars c¹ and rest upon the tube a. These blocks c are counterparts of
the blocks 6 previously described and are arranged directly above them.
Ag
dd are the strips with which the blocks are provided as above referred to.
These strips may be cemented or fastened to the blocks and their edges may be
connected together on opposite sides of the tube a in any suitable manner.
indicated in Figures 2 and 3 this connection is effected by means of lugs or loops d'
of which those on one strap alternate with those on the other, and through which
a pin is passed in a longitudinal direction. This pin has a hinged point ³

page_text: which can be turned down into the position indicated in Figure 3 and will then
serve to prevent the pin working out of the loops.
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
1. A wheeled vehicle having its body supported by blocks and an inflated tube
or tubes substantially as hereinbefore described.
2. The means substantially as hereinbefore described with reference to the
accompanying drawings for preventing or reducing vibration in wheeled vehicles.
