I ROBERT COOKE SAYER of 11 Clyde Road Redland Bristol Civil Engineer
do hereby declare the nature of this invention to be as follows:-
A fish or weld jointed rail having alternately spaced toothed flanges on each side
of its heads is secured to and supported by a longitudinal plate having a felt cushion
between the plate rests upon concrete to which the whole is bolted down, and in
the case of roadways, lateral vertical plates enclose channels and support the rail to
which they are bolted, and are kept in the desired direction laterally by concrete
but with a course of dry sand against the plates from a little below the road
surface.
The channels are drained, have insulated electric conductors formed with vertical
wedge shaped teeth spaced to come below the spaces between the rail teeth, so that
wheels having the central part of their peripheries formed to run upon the head of
the ruil and act for traction purposes as usual, have upon the sides of their
peripheries teeth alternately pitched to suit those of the rail and act as ordinary
cog-wheels: the insides of the teeth are bevelled to suit the sides of the rail heads
between their teeth, and thus causes the wheels and the car carried by them to keep
in the desired direction independent of gauge.
:
The wheels carry on one or both sides small electrically insulated radial tubes
that pass through their tyres and teeth, these have springs and are able to contract
telescopically as the tubes rotate with the wheels they are acted upon by an
excentrically acting double toothed pinion that receives motion from a toothed
wheel carried by the main wheel, so that when the teeth of the wheels enter the
spaces between the teeth of the rails the radial tubes are projected forward into
the channel and against the vertical.wedge shaped teeth of the electric conductors
in both channels, and thus obtains the current voltage of both for locomotion or
other purposes which is transferred to concentric rings upon the wheels; thence to
the dynamo and where required and back to its source through the rail or other
suitable conductor.
When electricity is only used for subsidiary purposes, the current is obtained in
the same way, and also the motive power, when generated at central stations, by
the entrance of the radial tubes carrying an elastic ring that when it is forced
down, it hermetically closes the entrance to a pin, valve having connection with a
pipe which carries the power, so that the continued pressure of the tube opens the
valve allows the powers of either compressed air, water, or steam, to pass up the
tubes, in succession, through a non return valve and to the motors, brake cylinder
or where required. The radial tubes, as before, are electrically insulated and
their entrances carry contacts that take upon the conical support of the valve,
which is also a conductor, insulated from its connections, and carries by arms
the electric conductors so that as the motive power is received the electric power
is also.
i
In the case of light vehicles provided with spring toothed or cog-wheels to suit
those of the rails, they are run upon the rail at will and obtain the power or powers,
or off to run upon the roadways upon their cogs.

L
One or any number of main wheels, to suit weights to be carried and the power
desired, together with a pair of lateral wheels carries the car body direct, or a bogie
frame that with a second carries the car as usual: these lateral wheels are
flangeless, and spaced laterally to the gauge to be normally run over, and when
two or more gauges have to be run over additional lateral flangeless wheels are
provided, so that when the central main rail is available, and at crossing points
the usual rail for flange wheels are provided with spaces for the teeth of the said
main wheels, all railways, or roadways without lateral rails, are available for the
said car.
Each lateral wheel for the standard gauge rotates within a frame formed by a
prolongation of its journals and to which diagonal arms are attached and by which
it is hinged to the frame of the car, while on the other side of the frame vertical
tubes, or rods, are hinged to it at each end and also to vertical springs which carry
the car or bogie weight.
.
On the line of way where it is desired for the car to change from running upon
the ground level to a single elevated rail, a short length of lateral rail each side of
the centre carries the bogic or car, through small wheels and thus relieves the
weight from the main lateral wheels and enables them to gravitate, rest upon a
curved introductory length and so obtain a diagonal and relatively low elevation
until they are supported by the flanges of a girder, sides of a wall or other
support, meanwhile the car maintains its position, though advancing on the central
rail, and when the main lateral wheels have been secured in their new position by
automatically acting wedges or levers and the car is independent of the small lateral
wheels their rails are discontinued, the weight being taken by the springs as before
of the main lateral wheels.
At the end of the elevated single rail the car is again supported by the said
small wheels and the main laterals, when released, are gradually run up upon
inclines to their normal level until they again act upon and carry the weight of
the car.

I ROBERT COOKE SAYER of 11 Clyde. Road Redland Bristol 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 :-
See drawings where-
.DETAIL DESCRIPTION.
Sheet 1, Figs. 1 to 3 show in part front and side elevations and cross section
respectively a bogie car and its transfer from the ground level to an
elevated single
rail.
Sheet 2 Fig. 4 a longitudinal sectional elevation in part, of a bogie frame a main
driving pinion and wheel upon the rail, the means of obtaining its motive power,
and transfer wheel.

Sheet 4 Fig. 6, an elevation of a transfer wheel, and mode of action.
,
Sheet 5, Figs. 7, 8, 9 and 10 sectional details of the rail and means of obtaining
its motive powers.
A rail A welded or with fish joints A, and having alternately spaced toothed
flanges A a, Figs. 7 and 8, on each side of its heads is secured by bolts A'e to

page_text: concrete Ad through a longitudinal plate A c and felt cushion Ab: and in the
case of roadways, lateral vertical plates Af enclose channels and support the rail A
to which they are secured by bolts Ag and are kept in the desired direction laterally
by concrete but with a course of dry sand Cy against the plates from a little below
the road surface.
The channels are drained provided with insulated conductors B formed with
vertical wedge shaped teeth B'a spaced to come below the spaces between the rail
teeth A a, which for roads are covered by hinge covers Ah, formed singly or
connected in groupes, their lips rest on the rail A, sc that a spring plate on the car F,
Figs. 1 to 3, preceeding the wheels D, take under and raise them, and after passing
another closes them.
Main wheels D, Figs. 4 and 7 having the central part of their peripheries
formed to run upon the head. of the rail, and act for traction purposes as usual,
have upon the sides of their peripheries teeth Dalternately pitched to suit the
teeth Aa of the rail A, and act as ordinary cog wheels: the insides of the
teeth Dare bevelled off to suit the sides of the heads of the rail A between
their teeth Aa, and thus cause the wheels of the car F carried by them to keep the
desired direction independent of gauge. The wheels D carry on one or both sides
electrically insulated radial tubes Da, having lugs Dc electric contacts Dx, pass
through the teeth D, and the cog wheel bond De, that gives motion to a
pinion Dg formed in one with a pinion Dv and their spindle Dh: Dh is attached
by collar Dj to the leveis Dk and D1, Fig. 5 Sheet 1, links D m and Dn slotted,
rocking shaft Do, having joints Dp, Figs. 1 and 4, and sleeves T fixed between
bogies and cars F, and regulating levers W: the collar Dj, Fig. 7, connects the
spindle D to the slotted bell-crank D s, and angle Dt which by its return can
raise the tubes Da by their collars Du successively: the tubes Da have frictional
contact with flat rings D w, and when thrust down by pinion Dv acting on the
lugs Dc, successively with the bevel of the teeth Ba of conductors B in both
channels by contacts D. X, which supplies current to the dynamo J and where required
through the concentric rings Dw and back to its source through the wheel D and
rail A or other suitable conductor.
The dynamo J, Fig. 4, actuates the pinion K, that by teeth Ka pitched to suit
the teeth Dfgives motion to the wheel D. The concentric tapered ring Db with-
draws the tubes Da by the lugs Dc and prevents their acting centrifugally while
passing the pinion K.
.
When electricity is only used for subsidiary purposes, the current is obtained in
the same way, and also the motive power when generated at central stations, by
the entrance of the radial tubes D'a, Figs. 9 and 10, carrying an elastic ring Dy
that when forced down by pinion Dv hermetically closes the atmosphere from a pin
valve Cc having connection through an elbow Cf with a pipe C that carries the
power, opens the valve Cc allows the power of compressed air, water or steam to
pass up the tubes Da in succession through a non-return valve Ca and stuffing
boxes to concentric tubes Dw, and the motors J, break cylinder G and where
required the tubes Da as before are electrically insulated, and their entrances
carry electric contacts Dr that take upon the conical supports Cb of the
valve C c which is also an insulated conductor secured by bolts Ce and carries the
conductor B by teeth or arms Cd, so that the motive and electric powers are
received simultaneously.
In the case of light vehicles provided with spring toothed, or cog, wheels to suit
those of the rail A, they are run upon the rail A at will, and obtain the power or
powers: or are run off the rail A, after withdrawing their tubes Da, to run upon the
roadways upon their cogs.
One or any number of main wheels D, Figs. 1 to 3, 5 and 6, to suit the weights
to be carried, and the power desired, together with at least a pair of lateral
wheels E carries the car body F direct, or a bogie frame Fa: these lateral
wheels E are flangeless, spaced to the gauge to be normally run over, and when one
or more gauges have to be traversed. additional lateral flangeless wheels E are

page_text: provided, so that when the central main rail A is available, and when at crossing
points the usual rail for flange wheels are provided with spaces for the teeth of the
said main wheels D, all railways, or roadways without lateral rails are available for
the cars F.
When the cars F have to run over sections of ordinary railways, the main wheels D
are fixed on one side of the car F, the flangeless wheels E the other, so that each
may take on either rail.
The bogies or cars F, Fig. 4, have brake cylinders G the power for which comes
through supply and exhaust taps worked by levers carried by shaft Do, they are
single acting, their rams being returned by springs G, and act on strap brakes Dz
that embrace the flanges Dy of wheels D, by levers Gg and links Gh.
Each lateral wheel E for the standard. gauge rotates within a frame Ea,
Figs. 1 to 6, formed by a prolongation of its journals, to which diagonal arms Eb
are attached by which it is hinged to the frame Fa of the car Fat Ec, and
at Ed to the ends of tube links Ee, these are hinged also to plates Ef of
springs Eg, which slide vertically within guides Eh that are united on top, and
support the frame Fa which is carried, when wheels E are lowered, by pairs of
levers Ej that act against springs Ek: Ej are actuated by the rods and
levers El, Em and hand lever En, not shown. On the line of way where it is
desired for the car F to change from running upon the ground level to a single
elevated rail, a short length of lateral rails A 2, Figs. 1 to 3, each side of the centre
carries the bogie or car F temporarily on flangeless wheels Fb, and thus relieves
the weight from the main lateral wheels E, and enables them to gravitate, and run
upon a curved introductory length, or incline, and so obtain a diagonal and
relatively low elevation Ay, Figs. 3 and 5, until they are supported by the flanges
of a girder, sides of a wall or other support; meanwhile the car F maintains its
position, though advancing, on the central rail, and when the main lateral wheels E
have been secured in their new position by the automatically acting wedges Ej,
Fig. 6, and the car F is independent of the small lateral wheels F their rails are
discontinued, the weight being taken by the springs Eg as before.
At the end of the elevated rail the car F is again supported by the said
wheels Fb on other rails A z, and the wheels E when released are gradually run
up similar inclines to the ground level when they again carry the weight of the
car F.
THE WORKING IN THE CASE OF A BOGIE CAR F, WHERE EACH BOGIE
CONSISTS OF A FRAME Fa HAVING A PAIR OF WHEELS D, DRIVEN
BY ELECTRICITY THROUGH THE DYNAMO J, LATERAL WHEELS E AND
FOUR SMALL OUTER LATERAL WHEELS Fb.
Electric current is supplied to the conductors B: and when the lever W is
caused to actuate the shaft Do through the joints Dp, sleeves T, levers Dk,
slotted crank Ds, and D t, Fig. 7, the radials D'a are lowered and the spindle Dh
puts the pinion Dv into gear with their lugs Dc: the pinion Dg is always in gear
with its wheel De, Figs. 4 and 7; the current then goes from the conductor B,
Fig. 8, to the contacts D x tubes Da, ring Dwo and to the dynamo J and
back through the wheel D, the rail A, or other conductor to its source, and advances
the car F.
When the motive power is other than electric and obtained through the pipes C,
Figs. 9 and 10, the radial tubes Da are projected as before and their elastic
cushions Dy meet the cone Cb and further pressure tightens them, opens the pin
valve Cc and the power passes by pipe C valves Cc and Ca and tubes Da and
their stuffing boxes to ring tube Dw, Fig. 7, from which it goes as before to suitable
motors J and the cylinder G: the electric current is taken as before, except that the
teeth Ba, Fig. 8, of conductor B takes the form of arms Cd, Figs. 9 and 10,
through which it passes from B.
When the car F is transferred from the ground to an elevated rail A the

page_text: flangeless wheels F b, Figs. I to 3, take upon a short length of rails A z and support
the car Flaterally, the paths Ay of wheels E are gradually depressed_to A y,.
Figs. 3 and 5, and wheels E radiate on centres Ec, their link tubes Ee and
springs Eg lower to their new position, the levers Ej are thrust aside and returned
by springs Ek and support the car F. When the ground level is desired_the
wheels Fb again take on rails Az, the levers Ej are released by rods and levers Em,
and the inclined paths A y raise the wheels E until they again take the weight by
the springs Eg.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1st. The alternately toothed and bevel headed rails, its means of support by side
plates, concrete, sand and felt, forming side channels that are drained covering in
the spaces between the teeth and raising them before and returning them after the
passage of the wheels, where required: the main wheels with their bevelled teeth
to suit the rail so that both act for traction purposes, and keep the car in the
intended direction without gauge beyond the single rail: while the roadway is
without projection or groove: the radial telescopic flanged and glanded tubes that
pass through the wheel teeth, and when they are engaged with those of the rail,.
are projected beyond both by an excentric pinion which receives motion from the
wheel and so cause them to come in contact successively with the bevel faced teeth,.
or conical, electric conductors within the channels, alone, or in combination with
other powers carried in pipes in the channels that pass through valves, the tubes
and reservoirs, to the motors and brake cylinders, substantially as described and
shown on the drawings.
2nd. For the pair of lateral car supporting flangeless wheels, and small lateral
flangeless wheels, and temporarily taking the side weights of the car by the latter
during the transfer of the former by inclined paths, from the ground level to that.
suitable for an elevated single rail, or the reverse, while the central main wheels
continue upon the central rail: and being enabled to run such cars above the ground
level, or upon it on either one central rail, or with side rails of any, or many
gauges, formed for flange wheels or not substantially as described and shown on
the drawings.
3rd. For the adaptation of suitable parts of the whole arrangement, to the
requirements of existing railways and the like substantially as described and shown
on the drawings.
Dated this 18th day of July 1896.
