PROVISIONAL SPECIFICATION.
Improvements in Road and other Rollers.
I, GEORGE VINCENT KINGS, of Nutfield Villa, Ashperton, Ledbury, in the
County of Hereford, District Highway Surveyor, do hereby declare the nature of
this invention to be as follows:-
The object of this invention is to so construct a road or other roller that it may
be drawn by a traction engine, horse or other tractive power, that it will suit itself
to the surface over which it has to travel and that it may be turned within its own
length.
For the purposes of this invention I use two rollers connected together so as to
form in reality one roller by means of an axle passing through their centres and
provided with a flexible or universal joint in its centre to allow each roller to
rise or fall independently of the other so as to suit the surface over which it is
passing.
The ends of said axle are secured to the opposite sides of a suitable square
framework surrounding the rollers.
Projecting between the rollers and having one end connected to the centre of
the axle holding same together, is a suitable draw bar secured in a suitable manner
to front end of framework.
The front end of the middle drawbar has secured to it a suitable head for
connecting it to the traction engine or other suitable tractive power and a coil
plate spring is secured between said head and the end of the drawbar so as to
prevent a dead weight pull when starting the roller.
The outer end of each of the rollers is provided with a cylindrical projection for
the reception of a spring band brake, one end of said spring band being connected
to the square framework, whilst the nut on the opposite end works up and down a
screw provided with a suitable handle and revolving in a socket on said framework.
The object of said brake is to case the weight when descending an incline.

COMPLETE SPECIFICATION.
Improvements in Road and other Rollers.
1, GEORGE VINCENT KINGS, of Nutfield Villa, Ashperton, in the County of
Hereford, Surveyor, do hereby declare the nature of this invention and in what
manuer 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 so construct a road or other roller that it may
be drawn by traction-engine, horse, or other tractive power, that it will also suit
itself to the surface over which it has to travel, and that it may be turned within
its own length.
For the purposes of this invention I use one pair of rollers.
The pair of rollers are connected together so as to form in reality one roller, by
means of an axle passing through their centre and provided with a flexible or

page_text: universal joint in its centre to allow each roller to rise or fall independently of the
other so as to suit the surface over which it is passing..
The ends of the said axle are secured to the opposite sides of a suitable angle
iron framework surrounding the pair of rollers, and projecting from between the
rollers, having one end connected to the centre of the axle holding the same
together is a suitable draw bar, secured to front end of framework.
The ends of the axle are secured to the opposite sides of a suitable iron frame
surrounding the pair of rollers, and attached to the central joint is a bar which is
carried forward between the two rollers, and attached by a hinged or flexible joint
to the front end of the framework.
The front end of the framework has attached to it a sliding head for connecting
it to the traction engine or other tractive power, and a steel or other suitable
spring may be inserted between the said head and the front end of framework so as
to prevent a dead weight pull when starting the roller.
The outer ends of the rollers are provided with a cylindrical projection for the
reception of a spring band break one end of this spring being connected to the
framework, whilst the nut on the opposite end works up and down a screw provided
with a suitable handle and revolving in a socket on said framework.
The object of the said break is to ease the weight when descending an incline.
I will now describe my invention more fully, reference being made for that
purpose to the accompanying drawing.
Figure 1 is an elevation of my roller, and Figure 2 is a part sectional plan.
"A" is the hinged or flexible joint between the two halves of the roller. "B" the
drawbar which is attached thereto and "C" the flexible attachment of the drawbar
to the front end of framework at "D."
"E" is the head for attachment to the traction-engine or other tractive power,
terminating in a solid piece or coupling "F." Against this rests one end of the
coiled spring "G" the other end resting against a nut "H" of such size and shape
as to be prevented from turning by its position in the head "E." The pressure of
the spring is regulated by turning the bolt "K" which is threaded through the
nut "H."
Having now described the nature of my invention and the manner in which the
same is to be carried out, I state that what I claim is
1st. The use of a flexible joint or hinge between a pair of rollers to allow
the said rollers to adapt themselves to the curvature or inequalities of the ground
substantially as above described.
2nd. The use of a draw-bar attached to the said central hinge & secured to the
front part of the framework of the roller, either by a rigid connection or a flexible
joint substantially as above described.
3rd. The use of a coiled or other suitable spring and suitable drawbar in
connection with road rollers substantially as above described.
Dated this 22nd day of February 1894.
GEORGE VINCENT KINGS.
