of Westminster, and James Cleminson, of 7, Westminster Chambers aforesaid,
for an Invention of "IMPROVEMENTS IN THE METHOD OF AND APPARATUS
FOR FIXING TYRES ON RAILWAY AND TRAMWAY WHEELS, AND REMOVING

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
THE METHOD OF AND APPARATUS FOR FIXING TYRES ON RAILWAY AND TRAMWAY
WHEELS, AND REMOVING TYRES FROM SUCH WHEELS BY HYDRAULIC PRESSURE."
Our Invention relates to forcing tyres on to wheels by hydraulic pressure in
accordance with the Invention forming the subject of an application for Letters
Patent made by us the 28th day of October 1880, No. 4401, also to the removal of
tyres from wheels,
According to our present Invention the apparatus we employ is constructed
with a cylinder and ram or a series of cylinders, each provided with a ram
and having connected thereto hooks, claws, or clamps, serving to connect the
press cylinder or cylinders with the wheel body or with the tyre. In one
arrangement where one cylinder is used it is provided with a number of radial
arms to which the hooks or claws are hinged or jointed, and the ram is furnished
with a corresponding number of radial arms that serve to carry the tyre and force
it on to the wheel body, whilst the latter is held by the hooks or claws, or when a
tyre is to be taken off a wheel body, the radial arms of the ram may carry the
wheel body by means of an interposed ring, the tyre resting against the hooks or

page_text: claws whereby it is held whilst the ram forces the wheel body out of the tyre.
Means are provided for simultaneously adjusting the hooks or claws which are able
to assume an attitude in which their hooked portions all overlap the wheel body;
also an attitude in which their hooked portions all overlap the tyre; also attitudes
in which they do not overlap either the wheel body or the tyre. A convenient
mode by which we simultaneously adjust the attitude of the hooks or claws is by
means of an annular cam provided with a rack and supported on antifriction
wheels or rollers carried by brackets, this cam operating upon the hooks or claws
through antifriction wheels or rollers whose axes are capable of tilting motion.
When a number of cylinders are used according to our Invention-to operate
simultaneously upon the tyre or wheel body each cylinder is provided with a hook,
claw, or clamp formed with or secured thereto, and the hooks, claws, or clamps
overlap the wheel body whilst the plungers force on the tyre, or when a tyre is to
be removed the hooks, claws, or clamps overlap the tyre, whilst through an
interposed ring which may be of section, the plungers operate simultaneously to
force the wheel body out of the tyre.
The presses may be so arranged that the hooks, claws, or clamps pass up between
the arms of a spoke wheel to operate on the rim or tyre.
As is obvious apparatus may be constructed in various forms to operate on the
principle of our Invention, as hereinabove set forth.

the said Abraham Cornelis Uljée and James Cleminson in the Great Seal
Patent Office on the 22nd September 1881.
ABRAHAM CORNELIS ULJEE, of the Hague, in the Kingdom of the Netherlands,
but temporarily of 7, Westminster Chambers, of the City of Westminster, and
JAMES CLEMINSON, of 7, Westminster Chambers aforesaid. "IMPROVEMENTS IN
THE METHOD OF AND APPARATUS FOR FIXING TYRES ON RAILWAY AND TRAMWAY
WHEELS, AND REMOVING TYRES FROM SUCH WHEELS BY HYDRAULIC PRESSURE."
Our Invention relates to forcing tyres on to wheels by hydraulic pressure in
accordance with the Invention forming the subject of Letters Patent granted to us
the 28th day of October 1880, No. 4401, also to the removal of tyres from
wheels.
According to our present Invention the apparatus we employ is constructed with
a cylinder and ram or a series of cylinders, each provided with a ram, and having
connected thereto hooks, claws, or clamps, serving to connect the press cylinder or
cylinders with the wheel body or with the tyre. Figs. 1, 2, and 3 shew an
arrangement in which one cylinder A is used. It is provided with a number of
radial arms B, to which the hooks or claws C are hinged or jointed at C', and the
ram D is furnished with a corresponding number of radial arms E that serve to
carry the tyre F and force it on to the wheel body G whilst the latter is held by
the hooks or claws C; or when a tyre is to be taken off a wheel body, the radial
arms E of the ram D may carry the wheel body G by means of an interposed
ring H, the tyre F resting against the hooks or claws C whereby it is held whilst
the ram D forces the wheel body out of the tyre. Means are provided for
simultaneously adjusting the hooks or claws which are able to assume an attitude
in which their hooked portions all overlap the wheel body; also an attitude in
which their hooked portions all overlap the tyre; also attitudes in which they do.
not overlap either the wheel body or the tyre. A convenient mode by which we
simultaneously adjust the attitude of the hooks or claws is by means of an annular
cam I provided with a rack K and supported on antifriction wheels or rollers L
carried by brackets M, this cam operating upon the hooks or claws C through
antifriction wheels or rollers N whose axes are capable of tilting motion, as clearly
shewn in the Drawing.
Figs. 4 to 6 inclusive illustrate the use of a number of presses according to our
;Invention to operate simultaneously upon the tyre or wheel body. Fig. 4 being a
general plan showing four of the presses with hydraulic connections; Fig. 5 one of
the presses in position for forcing the tyre on to the rim of a wheel, and Fig. 6 a
like view of the press in position for forcing the tyre off a wheel body. Each
cylinder A¹ is provided with a hook, claw, or clamp C formed with or secured
thereto, and the hooks, claws, or clamps overlap the wheel body, whilst the
plungers D force on the tyre (see Fig. 5), or when a tyre is to be removed (see
Fig. 6) the hooks, claws, or clamps overlap the tyre, whilst through an interposed
ring H, which may be of L section, the plungers operate simultaneously to force the
wheel body out of the tyre.
The presses are so arranged that the hooks, claws, or clamps will pass up between
Twelve or other
the arms of a spoke wheel to operate on the rim or tyre.
convenient number of presses may be used.
It will be seen the whole of the presses are connected by hose or pipes O to a
hydraulic main P communicating with an accumulator (not shown) so that all the
O presses will operate simultaneously. Figs. 7 and 8 shew a modified construction of
press for use, as above described, with reference to Figs. 4 to 6, and will be readily

page_text: understood from the Drawing, from which it will be seen that the claws are made
detachable from their cylinders.
Having described the nature of our said Invention, and the manner of carrying it
into practical effect, we would have it understood that what we claim is,―
The use for forcing tyres on to railway and tramway wheels, and for removing
tyres from such wheels by hydraulic pressure, of apparatus constructed, arranged,
and operating substantially as hereinbefore described with reference respectively to
Figs. 1 to 3 inclusive, and to Figs. 4 to 6 inclusive, of the accompanying 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.
