PROVISIONAL SPECIFICATION left by the said Abraham Cornelis Uljée
and James Cleminson at the Office of the Commissioners of Patents on the
28th October 1880.
ABRAHAM CORNELIS ULJEE, of the Hague, in the Kingdom of the Netherlands,
but temporarily of 5, Westminster Chambers, in the City of Westminster, and
JAMES CLEMINSON, of 5, Westminster Chambers aforesaid. "IMPROVEMENTS IN
THE MANUFACTURE OF WHEELS FOR USE ON RAILWAYS AND TRAMWAYS."
One object of our Invention is to secure the tyres firmly on the wheel bodies in
such manner as to obviate the unequal stresses which often occur in tyres heated
and laid on by shrinking in the usual manner. For this purpose we form the
periphery of the wheel body or part, on which the tyre or a portion thereof is
designed to fit and take its bearings, of a somewhat conical shape, that is to say,
smaller in diameter at the outer side of the wheel than at the inner side; and we
make the internal circumference of the tyre or a portion thereof of corresponding
conical form to fit accurately on the periphery of the said wheel body or part, on
to which we force the tyre cold or without heating by hydraulic or other pressure,
thus dispensing with the shrinking process. Wheels of various descriptions may
be constructed according to this part of our Invention.
Another part of our Invention has reference to an improved construction of disc
wheel of the kind in which two discs each formed with a boss constitute, when
suitably fastened together with their bosses in juxta-position and in a common
axial line, a wheel body. We construct such wheels so that without removing or
disconnecting the discs the tyre may be removed and another substituted. This
improved construction of wheel when provided with a tyre forced on cold or
without heating, as hereinabove described, is as follows:-The two discs, with
bosses which are connected together as aforesaid, are of different diameters, one

page_text: disc, namely, that constituting the inner side of the wheel being of larger diameter
than the other or outer disc, which latter has its periphery of a somewhat conical
form, as and for the purpose hereinabove referred to. The tyre is at its inner side
recessed to receive a projecting portion or flange of the inner disc, against which
the inner side of the tyre bears when in place, and at the outer side the tyre, as
also the outer and smaller disc, are recessed to receive the projecting portions or
flanges of a suitable ring, through which and the tyre and the inner disc suitable
fastening bolts or rivets are passed. When in such wheels two sets of bolts or rivets
are employed near the periphery, namely, one set through the fastening ring and
discs and another set through the fastening ring, tyre, and inner disc, we provide
between the discs distance tubes or a distance ring constituting abutments or an
abutment for the outer disc.
Wheels according to this part of our Invention, that is to say, so arranged that
the tyre may be passed over the outer disc into position against the inner disc, or
in like manner removed without removing or disconnecting the discs themselves,
may in some cases have the tyres shrunk on to them instead of being forced on
according to the first part of our Invention.

by the said Abraham Cornelis Uljée and James Cleminson in the Great Seal
Patent Office on the 28th April 1881.
ABRAHAM CORNELIS ULJEE, of the Hague, in the Kingdom of the Netherlands,
but temporarily of 5, Westminster Chambers, in the City of Westminster, and
JAMES CLEMINSON, of 5, Westminster Chambers aforesaid." "IMPROVEMENTS IN
THE MANUFACTURE OF WHEELS FOR USE ON RAILWAYS AND TRAMWAYS."
One object of our Invention is to secure the tyres firmly on the wheel bodies in
such manner as to obviate the unequal stresses which often occur in tyres heated
and laid on by shrinking in the usual manner. For this purpose we form the
periphery of the wheel body or part, on which the tyre or a portion thereof is
designed to fit and take its bearing, of a somewhat conical shape, that is to say,
smaller in diameter at the outer side of the wheel than at the inner side, and we
make the internal circumference of the tyre, or a portion thereof, of corresponding
conical form to fit accurately on the periphery of the said wheel body or part on to
which we force the tyre cold or without heating by hydraulic or other pressure, and
thus dispensing with the shrinking process. Wheels of various descriptions may be
constructed according to this part of our Invention.
Another part of our Invention has reference to an improved construction of disc
wheel of the kind in which two discs, one or both of which is or are formed with a
boss, constitute when suitably fastened together about a common axial line a wheel
body. We construct such wheels so that without removing or disconnecting the
dises the tyre may be removed and another substituted. This improved construction
of wheel, when provided with a tyre forced on cold or without heating, as
hereinabove described, is as follows:-The two discs with bosses which are
connected together as aforesaid are of different diameters, one disc, namely, that
constituting the inner side of the wheel, being of larger diameter than the other or
outer disc, which latter has its periphery of a somewhat conical form as and for the
purpose hereinabove referred to. The tyre is at its inner side recessed to receive a
projecting portion or flange of the inner disc, against which the inner side of the
tyre bears when in place, and at the outer side the tyre, as also the outer aud
smaller disc, are recessed to receive the projecting portions or flanges of a suitable
ring, through which and the tyre and the inner disc suitable fastening bolts or
rivets are passed. When in such wheels two sets of bolts or rivets are employed
near the periphery, namely, one set through the fastening ring and discs and another
set through the fastening ring, tyre, and inner disc, we provide between the discs
distance tubes, or a distance ring constituting abutments, or an abutment for the
outer disc.
Wheels according to this part of our Invention, that is to say, so arranged that
the tyre may be passed over the outer disc into position against the inner disc, or
in like manner removed without removing or disconnecting the discs themselves,
may in some cases have the tyres shrunk on to them instead of being forced on
according to the first part of our Invention.
Referring to the accompanying Sheet of Drawings, Fig. 1 is a cross section of a
wheel tyre and part of a wheel body put together according to the first part of our
Invention, a being the tyre and b the wheel body. The wheel body is somewhat
smaller in diameter at the outer side of the wheel than at the inner side, and the
internal circumference of the tyre is of a corresponding form to fit thereon.
Fig. 2 is a side elevation of a disc wheel constructed according to our Invention
for use on railways and tramways, and Fig. 3 is an edge view of the same partly in
section.

page_text: Fig. 4 is a side elevation of a similar wheel slightly modified as regards its
details, and Fig. 5 is an edge view of the same partly in section.
Similar parts are denoted by like letters of reference in these four views.
A is the tyre, B the inner and B¹ the outer disc; C is a retaining ring; D, D, are
rivets connecting the inner disc, the tyre, and the retaining ring; E, E, are rivets
connecting the two discs and the retaining ring; F, F, are bolts connecting the
discs near the boss of the wheel; G is a distance tube, of which there is one to
each or the rivets E, E, to form an abutment between the two discs; H is a distance
piece or ring laid in the internal groove of the tyre. In Fig. 3 both discs are shewn
furnished with bosses, which together form the boss of the wheel, while in Fig. 5
the boss is formed entirely on the inner disc.
The tyre A is forced cold or without heating on to the discs B, B¹, which are
made slightly conical for the purpose, by hydraulic or other pressure, according to
our Invention.
The outer disc B¹ is of smaller diameter than the inner disc B, so that the tyre
can be removed and another substituted by passing it over the outer disc without
disconnecting the two discs, the tyre being normally kept in its place by the
fastening or retaining ring C.
It will be evident that our mode of putting on tyres whilst cold or not heated
may be adopted in various kinds of wheels in addition to those shewn on the
Drawings for use on railways and tramways.
Having now described the nature of the said Invention, and the manner in which
it is to be or may be performed or carried into practical effect, we would have it
understood that what we consider to be novel and original, and therefore claim as
secured to us under the Letters Patent hereinbefore in part recited, is,-
1. The method of securing tyres on wheels for railways and tramways in such
manner as to dispense with shrinkage, substantially as described.
2. The improved wheels for use on railways and tramways, substantially as
herein before described with reference respectively to Fig. 1, to Figs. 2 and 3, and
to Figs. 4 and 5 of the Drawings.
In witness whereof, I, the said James Cleminson, have hereunto set my hand
and seal, this Twenty seventh day of April, in the year of our Lord One
thousand eight hundred and eighty-one.
