COMPLETE SPECIFICATION.
Improvements in or relating to Wheels adapted for Rail or Road
Vehicles.
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 follow-
ing statement:-
The object is to provide adjustable flanges to wheels so that
1st. When they are raised the wheels may run on roadways and be guided in
any direction.
2nd. When the flanges are lowered the wheels may be kept in direction of a
pair of lateral rails as usual.
3rd. That a group of wheels fitted with the flanges carrying a bogie truck, and
a central adjustable double flanged wheel to run on a central rail, may be similarly
run on roadways, two rail, or one rail railway.
4th. That a bogie truck of four wheels, fitted with the flanges, two of the
wheels, one on each of a pair of rails shall be smaller than, and hinged to the
bearings of the others, and the smaller wheels raised clear of the rail simul-
taneously with the flanges of the larger wheels.
The object is attained as shown by the following Specification and three draw-
ings where
Fig. 1 is an elevation of a pair of lateral wheels.
Fig. 2 a part sectional elevation at a bed on Fig. 1 showing the central wheel.
Fig. 3 a plan of the same.
Fig. 4 a diagramatic elevation showing large and small lateral wheels of a
bogie.
DETAIL DESCRIPTION.
Four usual bogie truck wheels 1, 2 with their fellows 3 and 4, not shown are run
upon a pair of rails 20, having bearings 5 and springs 6 carrying the frame 7
to support the bogie pin 8, from which is suspended by the collar 9 and nuts 59
and '60, the bell-cranks 10 and 11 hinged on 9 at 12, links 13 and 14 stirrup 15
and bearings 16 and 17, the central double flanged or toothed wheel 18 to run
on the rail 19 as shown dotted. The wheels 1 to 4 are provided with adjustable
flanges 21 having a concentric ring 22 an aperture 25 through which it is
threaded upon a square part 52 of the axle 26, and apertures 27, springs 28
secured by bolts 29 to act on latch levers 30 that hinge at 31 having returns or
lugs to enter holes 32 in the wheels 1 to 4, when they come opposite them, and
side guides 33 to keep the latches 30 in place. Pins 34 are passed through the
wheels 1 to 4 for one end to act against the latches 30 the other end to enter an
annular channel 35 having arms 135 to which bell-cranks 37 two shown are
hinged at 36, to be acted upon by either end of the slot 38 of the rods 39, that
hinge on levers 40 carried on a rocking shaft 45 resting in bearings 55 supported
by the frame 44 on the bearings 5, the shaft 45 also carries by the levers 43 the
telescopic rods 41 spring 42 and friction wheels 23 and 24, one each side of the

page_text: ring 22 of the flanges 21. The rocking shafts 45 are actuated by bell-cranks 10
rods 46 and lever 47, by turning the right and left handed screw 48, that passes
through trunnioned nuts 49, with the handle 50, and gives motion to the wheel 18,
she flanges 21 of the wheels 1 to 4 and the latches 30.
For vehicles passing over sharp curves Fig. 4 two small wheels 102 are substi-
tuted for two of the wheels 1 to 4, one on each rail 20, and are carried on arms 100
hinged 99 to the bearings 5 of the larger wheels and instead of actuating the
flanges 21 of the smaller wheels 102 the wheels themselves are raised clear of the
rails 20 by rods 141 hinged at 142 simultaneously with the flanges 21 of the
larger wheels.
The working is as follows:-The centre wheel 18 being raised above the rail 19,
the wheels 1 to 4, as shown, are guided by and upon the two rails 20 by their
flanges 21 which are fixed and rotated by the axles 26 and latches 30.
When a single rail 19 section of the railway is reached, and it is desired the
wheel 18 shall guide the vehicle, and the wheels 1 to 4 traverse the rails 20, the
handle 50 is turned to thrust the cranks 10 to their dotted position and the
wheel 18 is lowered near to, or upon the rail 19 to take more or less of the load
according to the adjustment of the collar 9 by the nuts 59 and 60. Simul-
taneously motion is given to the parts 46, 47, 45, 43, 42, 41, 23 and 24 to raise
the flanges 21 of all the wheels 1 to 4 to the dotted position 51 by putting the
springs 42 in tension, and just before the end of the stroke the levers 40 and
rods 39 thrust down the cranks 37 to drive in the ring 35 and pins 34 by the
arms 135 the returns of the latches 30 to clear the wheels 1 to 4, compressing the
springs 28, and the springs 42 draw up the flanges 21 of the wheels 1 to 4 by the
wheels 23 and 24 until the circular part of the aperture 25 becomes concentric
with the axle 26 and allows its square member 52, that rotated the disc and
flange 21 to rotate, as before, but without them.
When the operation is reversed the wheels 23 and 24 thrust down the flanges 21
and the slot 38 releases the cranks 37, enabling the springs 28 to thrust the
returns of the latches 30, into the wheels 1 to 4 to secure them.
When the vehicle reaches the end of the rails 20 the wheels 1 to 4 traverse the
surface of the roadway the wheel 18 guiding the vehicle by the rail 19 as before
When the vehicle reaches the end of the rail 19 the wheel 18 is raised by the
nuts 59 and 60 until clear of the roadway, and the usual mode of uiding vehicles
on roads obtain.
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 —
:
1st. A means of adjusting flanges to the wheels of vehicles so that when they
are up the wheels may be run in any direction, and when down be guided by the
flanges acting against rails the wheels traverse substantially as described and
shown on the drawings.
2nd. A means of adjusting flanges to the lateral wheels of vehicles in com-
bination with a central, double flanged or double seried tooth adjustable wheel,
carried on the vehicle so that when the flanges are up and the lateral wheels run
on their rails or the roadway the central wheel is lowered upon a central rail to
keep the vehicle in its direction and carry a part of the load of the vehicle or
none, substantially as described and shown on the drawings.
3rd. In a four wheeled bogie truck carrying the end of a vehicle, forming one
wheel to run on each of a pair of rails larger than and hinged to the bearings of
the other and having their flanges adjustable, while that of the smaller wheels
are fixed upon then together with vertically actuating the smaller wheels simul-
taneously with the flange of the larger substantially as described and shown on
the drawings.
4th. A means of fixing adjustable flanges to the wheels of vehicles consisting
of a loose flange 21 in one with a disc, a hole 25 through which to pass the axle 26

page_text: of a wheel to turn it when down or be fixed when up, an annular flange 22, ad-
justing wheels 23 and 24, latches 30 able to be thrust into and secured upon the
wheel by springs 28, pins 34 able to slide within holes in the wheel and act against
the latches 30 when thrust in, a ring 35 to thrust in the pins 34 and release the
latches 30 from the wheel when actuated by parts 37, 38, 39, 40, 45, 47, 46, 10,
49, 48 and a handle 50 which also actuates parts 43, 42, 41 and wheels 23
and 24 to raise the flange 21 and bring the hole 25 concentric to the axle 26
and allow it to rotate without the flange 21 substantially as described and shown
on the drawings.
