PROVISIONAL SPECIFICATION.
Improvements in or connected with Springs for Vehicles, and in the
Means of Attaching the same thereto.
I, JOHN EDWARD BUCKINGHAM, of 4 Marsden Road, East Dulwich, in the
County of Surrey, Coachman, do hereby declare the nature of this invention to be
as follows:-
The object of this invention is to eliminate the noise and vibration caused by the
passage of omnibuses and other vehicles over rough roads.
Springs of omnibuses and like vehicles as at present constructed are made of
several pieces each of which is in metallic contact with the next but not rigidly
connected thereto consequently unpleasant vibration and rattle is caused by the
component parts striking one against the other.
Also such springs are usually attached to the vehicle by bolts fitting loosely in
eyes formed in the spring and in the brackets to which they are attached which
further increases the noise and vibration.
Now according to this invention I interpose a strip of rubber vulcanised fibre
felt or other suitable material between each plate forming the spring and I bush
the holes in the ends of the spring with rubber or other suitable material.
The springs are secured to the vehicle by means of brackets formed with jaws
to receive the spring and above the spring I place a piece of thick rubber or other
suitable elastic material on which rests the end of the spring.
The bolts pass through slot holes in the bracket to allow of the compression of
the rubber.
In vehicles such as omnibuses in which cross springs are used in addition to the
longitudinal springs I either cover or line the shackles or stirrups with rubber or
vulcanised fibre or preferably attach the springs to each other in the manner
following.
I
To each spring in place of the usual shackle or stirrup I attach a cup having two
ears formed thereon through which passes the usual bolt the concave portion of the
cup attached to the cross spring being downwards, and the concave portion of the
cup attached to the longitudinal spring being upwards and between the cups
place a ball of rubber or other suitable elastic material the ball being large enough
prevent the cups from tonching each other when fully compressed.
connect the upper and lower springs carrying the front axle as follows:-
to
Either the upper or lower spring has slotted ears at each end through which
slots pass the usual bolt a piece of rubber being inserted between the ends of the
springs to keep them from contact with each other.

Means of Attaching the same thereto.
I, JOHN EDWARD BUCKINGHAM of 4 Marsden Road East Dulwich in the
County of Surrey, Coachman, 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 :-
The object of this invention is to eliminate the noise and vibration caused by the
passage of omnibusses and other vehicles over rough roads.
Springs of omnibusses and like vehicles as at present constructed are made of
several pieces each of which is in metallic contact with the next but not rigidly
connected thereto consequently unpleasant vibration and rattle is caused by the
component parts striking one against the other.
Also such springs are usually attached to the vehicle by bolts fitting loosely in
eyes formed in the springs and in the brackets to which they are attached which
further increases the noise and vibration.
Now according to this invention the springs are secured to the vehicle by means
of brackets formed with jaws to receive the spring and above the spring I place a
piece of thick rubber or other suitable elastic material on which rests the end of
the spring.
The bolts pass through slot holes in the bracket to allow of the
compression of the rubber.
In vehicles such as omnibusses in which.cross springs are used in addition to the
longitudinal springs I either cover or line the shackles or stirrups with rubber or
vulcanised fibre or preferably attach the springs to each other in the manner
following.
To each spring in place of the usual shackle or stirrup I attach a cup having
two ears formed thereon through which passes the usual bolt, the concave portion
of the cup attached to the cross spring being downwards and the concave portion
of the cup attached to the longitudinal spring being upwards and between the cups
I place a ball of rubber or other suitable elastic material the ball being large
enough to prevent the cups from touching each other when fully compressed.
I connect the upper and lower springs carrying the front axle follows.
Either the upper or lower spring has slotted ears at each end through which
slots pass the usual bolts a piece of rubber being inserted between the ends of the
springs to keep them from contact with each other.
as
And in order that my said invention may be fully understood I will proceed to
explain the same
With reference to the accompanying sheets of drawings in which
Fig. 1 represents side view of an omnibus fitted with springs constructed and
attached to the vehicle according to this invention.

back and cross springs.

ordinary scroll iron the front end of the back spring is secured to the body of
the vehicle by means of a bracket f having two cheeks or a jaw to receive the
front end of the spring this jaw has a piece of rubber g inserted therein above
the spring. The cheeks also are slotted at n to allow the end of the spring to move
up and down as the rubber is compressed or otherwise i is a bolt to secure the
rubber in its place.
The rear ends of the springs have connected thereto instead of the ordinary
shackles metal cups k see Figs 3 4 5 6 having ears provided with bolt holes.

To the ends of the cross spring are attached similar cups k¹ see Figs. 5 and 6.
having ears thereon to receive the bolts and between the cups k k¹ I interpose
indiarubber balls m the balls being large enough to prevent the cups k k¹ from
coming in contact with each other when the vehicle is fully loaded.
Instead of the cups kk I may use stirrups k see Figs. 7 and 8 connected to
the back and cross springs and instead of the balls m I may use barrel shaped
pieces of indiarubber m' Fig. 8 the said rubber being swelled sufficiently in the
centre thereof to prevent the stirrups from touching each other.
Each end of the upper or lower front spring is formed with slotted ears as
shewn at n Fig. 11 and between the ears I place a piece of rubber; the ends
of the other spring are formed with eyes o Fig. 12 to receive bolts in the
usual way.
The springs are placed in position and compressed until the bolts will pass
through the slots in the ears n and eyes o a second bolt p serves to keep the rubber
in position.
Vehicles fitted with springs constructed as hereinbefore described will be found
to travel more easily and with less noise than those of the ordinary construction
the comfort also of the passengers is largely increased owing to absence of noise
and vibration.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is
1. In the construction of springs for vehicles the combination with the back and
cross springs of metal cups or stirrups attached to the said springs and balls or
other suitably shaped pieces of indiarubber interposed between the said cups or
stirrups substantially as herein before specified and shewn at Figures 3. 4. 5. 6. 7
and 8 of the accompanying drawings for the purpose stated.
2. In the construction of springs for vehicles the combination of a spring of the
usual construction attached to the front axle with a spring having slotted ears n
formed thereon attached to the fore carriage and a piece of indiarubber interposed
between the ends of the said springs substantially as hereinbefore specified and
shewn by Figs. 11 and 12 of the accompanying drawings.
3. In the construction of springs for vehicles the combination of a spring of the
usual construction attached to the fore carriage with a spring having slotted ears n
thereon attached to the front axle and a piece of indiarubber between the ends of
the said springs all substantially as hereinbefore specified.
4. Attaching the back springs of vehicles to the bodies thereof by means of
bolts passing through slots in brackets such as f in combination with pieces of
indiarubber such as g interposed between the spring and the upper part of the said
bracket substantially as hereinbefore specified and for the purpose stated.

accompanying drawings and attached to the vehicle and to each other in the manner
stated.
