I, THOMAS EDWARD KNIGHTLEY of 106 Cannon Street in the City of London
Surveyor do hereby declare the nature of this invention to be as follows:-
A
The tram-car or other vehicle I form with a locking carriage at each end-each
carriage composed of a ring capable of swivelling or traversing around a fixed ring
on the underside of the body of the car and of framework attached thereto.
projecting flange from the inner circumference of the traversing ring entering a
groove in the outer circumference of the fixed ring keeps the traversing ring in place.
Two chains or flexible bands are secured to the circumference of each ring and pass
from one ring to the other crossing one another as they pass so that when one ring
turns in one direction the other turns to an equal extent in the opposite direction.
Each ring at two opposite points of its circumference has a spring secured to it-the
springs are secured to an axle which has a wheel mounted upon it at each of its ends.
I also connect both the axle and the traversing ring by stays or bars with the front
bar of the locking carriage.
Two frames each carrying two brake blocks one for acting against each wheel are
also hung from two opposite points of the ring so that the blocks on one frame may
be made to act against the front of the wheels and the block on the other frame
against the back of the wheels. To draw the two sets of brake blocks against the
wheels I employ cords, chains, links, levers, or other gearing so arranged that the
power transmitted from the breaksman to the brakes is led to and from or around a
point central with regard to the common axis of the traversing and fixed rings.
In this way the car can not only be made to turn in curves of very small radius
but the tractive force is applied to both body and axles and in addition the brakes
act equally well in whatever position the wheel axles may be turned.

1, THOMAS EDWARD KNIGHTLEY of 106 Cannon Street in the City of London
Surveyor 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 tram car or other vehicle I form with a locking carriage at each end-each 5
carriage composed of a ring capable of swivelling or traversing around a fixed ring
on the underside of the body of the car and of framework attached thereto. A
projecting flange from the inner circumference of the traversing ring entering a
groove in the outer circumference of the fixed ring keeps the traversing ring in place.
Two chains or flexible bands are secured to the circumference of each ring and pass
from one ring to the other crossing one another as they pass so that when one ring
turns in one direction the other turns to an equal extent in the opposite direction.
Each ring at two opposite points of its circumference has a spring secured to it-
the springs are secured to an axle which has a wheel mounted upon it at each of its
ends. I also connect both the axle and the traversing ring by stays or bars with the
front bar of the locking carriage.
Two frames each carrying two brake blocks one for acting against each wheel
are also hung from two opposite points of the ring so that the blocks on one frame
may be made to act against the front of the wheels and the blocks on the other frame
against the back of the wheels. To draw the two sets of brake blocks against the
wheels I employ cords, chains, links, levers or other gearing so arranged that the
power transmitted from the brakesman to the brakes is led to and from or around a
point central with regard to the common axis of the traversing and fixed rings.
In this way the car can not only be made to turn in curves of very small radius but
the tractive force is applied to both body and axles and in addition the brakes act
equally well in whatever position the wheel axles may be turned.
Figure 1 of the drawings hereunto annexed is a cross section Figure 2 a longi-
tudinal section and Figure 3 a plan of the lower part of a tram car formed as
above described.
A is the swivelling ring at each end on the underside of the body of the car, B, B, are
springs secured to opposite sides of each ring and also to an axle C which has a
wheel D on each of its ends. Swivelling rings turn as shewn around fixed rings E
which project from the underside of the body of the car. F. F. are two chains secured
at their ends to the circumference of each swivelling ring-and crossing one another
as they pass from one ring to the other. G. G. are arms projecting from the swivelling
rings and formed with sockets H at their ends for receiving the pole. I. I. are stays
passing backwards from the armis G to pins K, which project downwards from the
axle C, the pins can work freely through holes in the arms so that the springs B can
play freely up and down. L. L. are two swinging frames one in front and the other

page_text: in rear of each pair of wheels and each carrying two brake blocks one to bear against
one wheel and the other against the other.
The joints upon which the frames swing are carried by the swivelling rings-
M are chains passing from the frames to a cylinder N which is in the centre of the
fixed ring E around which the rings A swivel. The cylinder N has also a chain O,
wound around it and led to an axis P, which can be turned by a crank handle on its
upper end.
By turning the axis P by its crank handle the chain O can be wound up onto it
and the cylinder N be thereby made to wind on to itself the chains M and draw the
brake blocks against the wheels.
It will be seen that as the axis P is carried by the arms G and the cylinders N are
concentric with the rings A that the brakes can be applied equally well whether the
car is running along a straight or a curved track.
R is a ratchet wheel on the brake axis and S a pawl which can be made to engage
with the ratchet wheel and lock the axis from turning whenever required.
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. The arrangement of the swivelling rings A turning around fixed rings E on
the underside of the body of a tram car or other vehicle and coupled as described
by chains F.
2. Also in combination with the above the swinging frames carrying brake blocks
and coupled by chains or cords to a cylinder concentric with the rings so that by
turning the cylinder the brakes may be applied where the car is running along a
straight or a curved track.
3. A tram car or other vehicle provided with locking carriages and brake mechanism
substantially in the manner herein before described and illustrated in the drawings
annexed.
