page_text: I, CHARLES CHRISTOPHER BRAITHWAITE, of 35 King William Street, in the City
of London, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention has for object to prevent tyres from turning upon the rims felloes
or centres of railway wheels as they are liable to do when powerful brakes are
applied. For this purpose I form at intervals around the wheel centre and tyre
where they meet, at one side, or at both sides, or entirely through both wheel rim
felloe or centre and tyre, transverse holes into which pins plugs or keys are
inserted so that each takes partly into the outer circumference of the rim felloe or
centre and partly into the inner circumference of the tyre,-In some cases the pins
plugs or keys may be provided at their outer ends with projections or flanges
arranged to overlap the face of the tyre and to be secured thereto.
My invention may be applied in wheels of various constructions including such
as are provided with flanged rings or plates for securing the tyres to the rims
felloes or centres.

This invention has for object to prevent tyres from turning upon the rims or
centres of railway wheels as they are liable to do when powerful brakes are
applied. For this purpose I form at intervals around the wheel centre and tyre
where they meet at one side or at both sides or entirely through both wheel rim or
centre and tyre transverse holes into which pins plugs or keys are inserted so that
each takes partly into the outer circumference of the rim or centre and partly into
the inner circumference of the tyre. In some cases the pins plugs or keys may be
provided at their outer ends with projections or flanges arranged to overlap the
face of the tyre and to be secured thereto.
My invention may be applied in wheels of various constructions including auch
as are provided with flanged rings or plates for securing the tyres to the rims or
centres.
Figs. 1. 2. 3. 4. 5. 6. 7. and 8. of the annexed drawings illustrate in cross section
different applications of my invention. Fig. 9. is the side elevation of a wheel, to
a reduced scale, showing the arrangement around the periphery of the wheel of the
holes to receive pins plugs or keys according to my invention the fastening ring for
securing the tyre to the wheel being omitted.
Fig. 10. is a side view to a still smaller scale of a complete wheel according to
one construction.
According to Fig. 1. the wheel rim A and tyre B which are held together by
fastening rings C C¹ and transverse bolts D as well understood, are formed at
intervals around the rim and tyre where they meet with transverse holes arranged
at the inner side and extending only partly through the rim and tyre, and into these
holes pins E of corresponding length are inserted.
According to Fig. 2. the pins E are at the outer side of the wheel. According to
Fig. 3. the pin is shown as extending entirely through both wheel rim and tyre.
According to Fig. 4. the holes for the pins E extend through one of the rings
whereby the tyre B is secured to the wheel body A, and a short distance between
the periphery of the wheel body and inner circumference of the tyre. According
to Fig. 5. the pin E is formed with a shoulder E'; its larger end is inserted into
the hole between the wheel body A and tyre B. When all the pins have been
inserted the ring C is put on the reduced ends of the pins passing through corre-
sponding holes in the ring, and afterwards the outer ends of the pins are rivetted
or upset as shown. According to Fig. 6. the pins are formed with threads for a
part of their length to screw into the ring C which is put in place after the pins
have been screwed into it. According to Fig. 7. the pins somewhat resemble
that illustrated in Fig. 5. but the reduced outer ends of the pins are dispensed
with. The holes E* Figs. 4. and 7. enable the pins to be seen. According to Fig. 8.
that part of the pin that enters between the wheel rim and the tyre is formed as
a screw.

page_text: 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
For the purpose of preventing tyres from turning upon the rims or centres of
railway wheels, providing at intervals around the wheel centre and tyre, where
they meet, at one side, or at both sides, or entirely through both wheel rim or
centre and tyre, transverse holes into which pins plugs or keys are inserted, so that
each takes partly into the outer circumference of the rim or centre, and partly into
the inner circumference of the tyre substantially as hereinabove described.
