We HARRY EDMUND WINTER, 30 Palace Street, Buckingham Gate, Middlesex,
Gentleman, JEAN LODOÏS MÉRIGOT, 56 Conduit Street, Regent Street, Middlesex,
Medical Electrician, and WALTER FROST, 92 Copeland Road, Peckham Rye,
Surrey, Electrical Engineer do hereby declare the nature of the said invention
for "IMPROVEMENTS IN WHEELS AND AXLES FOR RAILWAY, TRAMWAY OR OTHER
ROLLING STOCK to be as follows:-
"
The object of our invention is the construction of wheels and axles for railway,
tramway or other rolling stock so that the wheels shall be independent of each
other in their action, this being effected in a simple manner; the improvements can
be easily applied to wheels and axles at present in use; the wheels are free to rotate
if required, in opposite directions, on one and the same axle, for example in
travelling over curves on railways the outer rail being much longer than the inner rail,
it follows that the outer wheel ought properly to travel proportionately faster than
the inner wheel on the same axle; where the wheels and the axle are made rigidly
fast to cach other as as hitherto been the case one wheel must travel at the same
rate as the other and in doing so they necessarily slide and skid over the rails,
instead of travelling thereon independently as is the case with wheels and axles
constructed according to our improvements by which each wheel is allowed to
give the necessary revolutions and conform to the requirements of the respective
rail on which it runs.
The friction on both wheels and rails is considerably reduced, thereby effecting a
great saving in the wear and tear of both rails and rolling stock and lessening at
the same time the lateral shocks and vibration of the carriages and consequently
rendering travelling much easier.
In carrying out our invention we fix rigidly on the axle a wheel at one end as
in the ordinary way and at the other end of the same axle is fixed a plate with a
projecting collar having one or more holes to receive bolts or screws; on this
projecting collar and against the said plate is fitted the other wheel and another
plate is placed on the axle and bolted or screwed tightly against the said projecting
collar, by means of bolts or screws passing through the holes therein, the wheel
being allowed to freely revolve on the collar or the wheel may revolve on the
axle itself if desired in which case the projecting collar would not be required
the wheel being held firm and prevented from shaking by being placed between
the plates.

"
The object of our invention is the construction of wheels and axles for railway,
tramway or other rolling stock so that the wheels shall be independent of each
other in their action this being effected in a simple manner; the improvements can
be easily applied to wheels and axles at present in use; the wheels are free
to rotate if required in opposite directions, on one and the same axle, for
example in travelling over curves on railways the outer rail being much longer
than the inner rail it follows that the outer wheel ought properly to travel
proportionately faster than the inner wheel on ..the same. axle ;- where the wheels
and the axle are made rigidly fast to each other as has hitherto been the case one
wheel must travel at the same rate as the other and in doing so they necessarily
slide and skid over the rails, instead of travelling thereon independently as is
the case with wheels and axles constructed according to our improvements by
which each wheel is allowed to give the necessary revolutions and conform to the
requirements of the respective rail on which it runs.
t
The friction on both wheels and rails is considerably reduced thereby effecting a
great saving in the wear and tear of both rails and rolling stock and lessening at
the same time the lateral shocks and vibration of the carriages and consequently
rendering travelling much easier.
In carrying out our invention we fix rigidly on the axle a wheel at one end as
in the ordinary way and at the other end of the same axle is fixed a plate with a
projecting collar having one or more holes to receive bolts or screws; on this
projecting collar and against the said plate is fitted the other wheel and another
plate is placed on the axle and bolted or screwed tightly against the said projecting
collar by means of bolts or screws passing through the holes therein, the wheel
being allowed to freely revolve on the collar or the wheel may revolve on the
axle itself if desired in which case the projecting collar would not be required the
wheel being held firm and prevented from shaking by being placed between
the plates.
In order to enable our invention to be fully understood we will proceed to
describe the same by reference to the accompanying drawing in which figure 1
represents a cross section of a pair of wheels on their axle constructed to act
independently of each other according to our invention and suitable for the smaller
kinds of rolling stock such as mining trucks and the like, the loosely revolving
wheel turning on a collar projecting from one of the fixed plates; figure 2, is a
similar view to figure 1, but shewing the loose wheel arranged to revolve on the
axle itself and suitable for the larger kinds of rolling stock such as railway wheels.
Similar letters in both the figures represent similar parts.
In figure 1, a is the wheel fixed rigidly on one end of the axle b, of the truck or
the like in the ordinary manner; c is the plate having a projecting collar & and
fixed rigidly on the other end of the axle b; e, is the other wheel fitted on the
collard, and against the plate c, so as to revolve freely on the said collar d; fis
the other plate which is placed on the axle b, and g, are the bolts passing through
10

page_text: holes in the plate c and f, by means of which bolts g, provided with screw nuts h,
the, plate f, is fixed tightly against the projecting collar d, the wheel e being thus
allowed to revolve freely on the said collar and kept in position thereon by the
plates c and f
Instead of the said bolts g and nuts h we may fix the two plates c and f and
the collar & together by any other suitable means such as by screws passing into
correspondingly threaded holes.
The arrangement shewn in figure 2 is similar to that hereinbefore described and
shewn in figure 1 except that the collar d is dispensed with and the wheel e is
adapted to revolve freely on the axle b itself, the plates. c and f being fixed
rigidly on the axle b on each side of the wheel as shewn whereby the wheel is held
firmly and prevented from shaking.
.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
(1) In an axle and pair of wheels for railway tramway and other rolling stock
the use of a plate with another plate having a collar substantially as and for the
purposes hereinbefore described and represented in figure 1 of the accompanying
drawing.
(2) The arrangement shewn in figure 2 of the accompanying drawing in which
one of the pair of wheels is adapted to. rotate freely on the axis itself between
two plates fixed rigidly on the axle substantially as herein before described and
represented in figure 2 of the accompanying drawing.
(3) The improved wheels and axles as hereinbefore described and represented in
the accompanying drawing.
