page_text: LETTERS PATENT to Abraham Cornelis Uljée, of the Hague, in the Kingdom
of the Netherlands, but temporarily of 7, Westminster Chambers, in the City
of Westminster, and James Cleminson, of 7, Westminster Chambers aforesaid,
for an Invention of "IMPROVEMENTS IN WHEELS FOR USE ON RAILWAYS
AND TRAMWAYS."
PROVISIONAL SPECIFICATION left by the said Abraham Cornelis Uljée and
James Cleminson at the Office of the Commissioners of Patents on the
22nd March 1881.
ABRAHAM CORNELIS ULJÉE, of the Hague, in the Kingdom of the Netherlands,
but temporarily of 7, Westminster Chambers, in the City of Westminster, and
JAMES CLEMINSON, of 7, Westminster Chambers aforesaid. "IMPROVEMENTS IN
WHEELS FOR USE ON RAILWAYS AND TRAMWAYS."
In the Specification of a former Patent granted to one of us, the said James
Cleminson, and dated the 17 May 1879, No. 1980, there is described a method of
preventing tyres slipping round upon the centres of wheels without neutralizing or
counteracting the elasticity or cushioning action of the filling material, and our
present Invention has reference to modifications of wheels embodying this principle
of construction.
We construct a wheel of the following principal portions secured together by
bolts or rivets, namely:-(1) a half centre, having formed with it shallow radial
arms or spokes and a flanged tyre retaining ring; (2) a half centre without radial
arms or spokes; (3) a tyre retaining ring, having formed with it a number of
shallow arms or spokes converging towards a common centre (the wheel's axis),
and connected together at their inner ends; and (4) a disc or body of compressed
teak or other comparatively elastic substance forming a cushion, which may be in .
one piece or several; conveniently it may be composed of as many segments or
parts as there are radial arms or spokes at one side of the wheel. There is
interposed between the two half centres above mentioned a ring, which may be
i

page_text: formed as a separate piece or pieces, or may be in one with the one half centre.
From this ring there extend radial projections, between which enter the inner
extremities of the elastic segments. The flanges of the tyre retaining rings enter
recesses in the sides of the tyre, and recesses are provided in the tyre to receive
the ends of the shallow radial arms or spokes, so as to prevent the tyres slipping
round without neutralizing or counteracting the elasticity or cushioning action of
the filling material.
Instead of the ends of the shallow radial arms or spokes entering recesses in the
tyre, the tyre retaining rings formed with the said arms or spokes may have their
faces flush with the faces of such arms or spokes, and be made each with a flange
deepened at intervals corresponding to the recesses in the tyre so as to enter
therein and prevent the tyre turning on the wheel body.
In a modified construction of wheel, having at both sides shallow radial arms or
spokes, whose extremities enter the recesses in the tyre, as and for the purpose
mentioned, we form the wheel centre in one piece, and with it the shallow radial
arms or spokes for one side of the wheel, as also the radial projections that enter
between the elastic segments, the tyre retaining rings being made separate from
the radial arms or spokes and secured by bolts or rivets.
To prevent slipping of the tyre in a wheel wherein a disc and fastening ring are
used to connect the tyre to the wheel centre, we form the disc with projections
that enter the recesses in the tyre in such manner that whilst preventing its
slipping round they do not neutralize or counteract the elasticity or cushioning
action.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Abraham Cornelis Uljée" and James Cleminson in the Great
Seal Patent Office on the 22nd September 1881.
ABRAHAM CORNELIS ULJÉE, of the Hague, in the Kingdom of the Netherlands,
late temporarily of 7, Westminster Chambers, in the City of Westminster, and
JAMES CLEMINSON, of 7, Westminster Chambers aforesaid. "IMPROVEMENTS IN
WHEELS FOR USE ON RAILWAYS AND TRAMWAYS."
In the Specification of a former Patent granted to one of us, the said James
Cleminson, and dated the 17th May 1879, No. 1980, there is described a method
of preventing tyres slipping round upon the centres of wheels without neutralising
or counteracting the elasticity or cushioning action of the filling material, and our
present Invention has reference to modifications of wheels embodying this principle
of construction.
Figs. 1, 2, 3, and 4 illustrate a wheel according to our Invention, Fig. 1 being an
outside elevation; Fig. 2, a cross section; Fig. 3, an enlarged part cross section in
the line a, c, of Fig. 1; and Fig. 4, a like section in the line a, b, of Fig. 1. This
wheel is constructed of the following principal portions secured together by bolts
or rivets, namely:-(1) a half centre A. having formed with it shallow radial arins
or spokes B and a flanged tyre retaining ring C; (2) a half centre D without
radial arms or spokes; (3) a tyre retaining ring E having formed with it a number
of shallow arms or spokes F converging towards a common centre (the wheel's
axis), and connected together at their inner ends by the half centre D; and (4) a
disc or body G of compressed teak or other comparatively elastic substance forming
a cushion, which may be in one piece or several; conveniently it may be composed
(as shown) of as many segments or parts as there are radial arms or spokes at one
side of the wheel. There is interposed between the two half centres A, D, above
mentioned a ring H, which may be formed as a separate piece or pieces, or may be
in one with the one half centre. From this ring there extend radial projections H¹,
between which enter the inner extremities of the elastic segments. The flanges of
the tyre retaining rings enter recesses in the sides of the tyre I, and recesses are
provided in the tyre to receive the ends of the shallow radial arms or spokes B, F,
(as clearly indicated in Fig. 4), so as to prevent the tyres slipping round without
neutralising or counteracting the elasticity or cushioning action of the filling
material.
Instead of the ends of the shallow radial arms or spokes entering recesses in the
tyre, the tyre retaining rings formed with the said arms or spokes may have their
faces flush with the faces of such arms or spokes and be made each with a flange,
deepened at intervals corresponding to the recesses in the tyre so as to enter
therein and prevent the tyre turning on the wheel body.
Figs. 5 and 6 shew a modified construction of wheel, having at both sides
shallow radial arms or spokes whose extremities enter the recesses in the tyre, as
and for the purpose mentioned. In this wheel the wheel centre K is formed all in
one piece, and with it the shallow radial arms or spokes B for one side of the
wheel, as also the radial projections H' that enter between the elastic segments
forming the disc or body G, the tyre retaining rings C and E being made separate
from the radial arms or spokes and secured by bolts L or rivets.
Figs. 7, 8, and 9 shew parts of a wheel wherein a disc and fastening ring are
used to connect the tyre to the wheel centre. To prevent slipping of the tyre in
such a wheel we form the disc M with projections N that enter the recesses o in
the tyre P, in such manner that whilst preventing its slipping round they do not
neutralise or counteract the elasticity or cushioning action. To this end, as will

page_text: be seen, there is all round a circumferential space between the disc and its
projections and the tyre, so that in a radial sense they are never at any part in
mutual contact.
Having described the nature of our said Invention and the manner of carrying
it into practical effect, what we claim is,—
1. The combination in a railway or tramway wheel of (a) a half centre, having
formed with it shallow radial arms or spokes and a flanged tyre retaining ring;
(b) a half centre without radial arms or spokes; (c) a tyre retaining ring, having
formed with it a number of shallow arms or spokes converging towards a common
centre (the wheel's axis), and connected together at their inner ends; and (d) a
disc or body of compressed teak or other comparatively elastic substance, sub-
stantially as hereinbefore described with reference to Figs. 1 to 4 of the Drawings.
2. Constructing railway and tramway wheels, substantially as hereinbefore
described with reference to Figs. 5 and 6 of the Drawings.
3. In a railway or tramway wheel wherein a disc and fastening ring are used
to connect the tyre to the wheel centre, the use of projections formed with the
disc in conjunction with recesses in the tyre, such projections being caused to enter
the recesses in the tyre in such manner that, whilst preventing its slipping round,
they shall not neutralise or counteract the elasticity or cushioning action of the
wheel, substantially as hereinbefore described with reference to Figs. 7, 8, and 9
of the Drawings.
In witness whereof; I, the said James Cleminson, have hereunto set my hand
and seal, this Twentieth day of September, in the year of our Lord One
thousand eight hundred and eighty-one.
