Improvements in Railway Carriage and other Wheels.
I, HEINRICH VAN HEESE, Engineer of Graskeller 21 Hamburg in the Empire
of Germany 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 following statement :-
This invention relates to the wheels of railway carriages and other heavy
vehicles and the purpose of the improvements is to connect the tire with the axle
in such a way that if a tire breaks or if for any other reason it is desirable to
change the tire this may be done without any special tools or machinery and with
comparative ease.
By the use of this invention railway carriages, heavy wagons trolleys and the
like may as respects the tires of the wheels be mended in the open at the place of
the break down provided spare tires are carried.
This invention also permits railway vehicles to travel on lines of different
gauges by changing tires withont much loss of time for others fitted for the
different gauge.
The accompanying drawing shows this invention as applied to the wheel of a
railway carriage.
Fig. 1 being a central cross section Fig. 2 an elevation half in section and
Fig. 3 a central cross section of a wheel fitted with a tire for a wider gauge
of line.
The improvements consist in connecting the tire C with the axle A by means
of two disks m m¹ each of which carries towards its centre an inwardly directed
flanged d' the one to embrace the axle the other to eurbrace the former, and each
of which disks also carries at its outer edge an inwardly directed flange taking
into a corresponding recess on each face of the tire C. In place of having the
two flanges d d the one to overlap the other, the two flanges may embrace a
central sleeve on the axle fast therein.
e e
To hold the tire fast to the disks the screw threaded bolts ss with nuts thereto
are arranged around the circumference to hold the disks firmly together. To
prevent the tire slipping between the disks when the brake is acting on the
tire, these bolts may project slightly into recesses on the inner edge of the tire as
shown in Fig. 2.
To change or remove one of the tires, the bolts ss are loosened and the disk m
is removed, the flange is then free and can be lifted off, and replaced by another.
To place a tire on the wheel adapted for a different gauge of line, tires shown in
Fig. 3 are employed; this tire is adapted for a wider gauge of line than that
shown in Fig. 1 the flange being set inward on the tire, or the tire being made
wider by a piece g.
If one wheel on each axle is provided with this flange C¹ the
carriage is adapted to travel on a line wider in gauge by the amount v, if both
wheels are provided with this flange the increase of gauge
is 2 v.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1) In wheels the combination with the axle of two disks m m³ having flanges d di
connected one over the other or each on a sleeve common to both on the axle
and having inwardly directed flanges e e, and a tire having recesses to receive
said flanges e e, and bolts for connecting the disks m m³, for the purpose set forth.

page_text: 2) In wheels with removable tires, a tire having on the inside of its flange an
addition g substantially as and for the purpose set forth.
