Improvements in Car Wheels.
I, FRANCIS DANIEL TAYLOR, of 103 Bay Street, of the City of Toronto, in
the County of York, in the Province of Ontario, Canada, Mining Engineer,. 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:
My invention relates to improvements in car wheels and the object of the
invention is to design a form of car wheel in which the impinging of the flanges
of the wheels upon the rails in going around a curve will be reduced to a minimum,
so as to prevent the wearing of the curved rails and at the same time provide means
whereby the wheels, will only have to be re-placed in part and it consists essentially
of forming the car wheel with a central hub and web and an outer rim and web
separate therefrom, the two portions being connected together by a ring of rubber
or other suitable material in the manner hereinafter more particularly explained.
Fig. 1, is a cross sectional perspective view of my car wheel.
Fig. 2, is a sectional perspective view of the rim and web.
Fig. 3, is a sectional perspective view of the hub and web.
Fig. 4, is a sectional perspective view of the yielding connecting ring.
Fig. 5, is a plan view partially in section of a truck with wheels constructed in
accordance with my invention as they appear in passing around the curved rails of
a'track.
In the drawings like letters of reference indicate corresponding parts in each
figure.
A, is the hub, which has an outwardly extending web portion A: B is the rim,
which has an inwardly extending web portion B' and the ordinary outwardly
extending flange B. The interior of the web B' is preferably provided with an
inwardly extending flange'b and is formed with a series of projections 6¹ around it.
The exterior periphery of the web A' is preferably provided with an outwardly
extending flange a, and has alsó formed around it a series of projections a² to the
one side of the flange.
C is a ring preferably of rubber but it may of course be made of any other
Buitable yielding elastic material of sufficient hardness to withstand much
compression. The ring C is fitted between the external periphery of the web and
the interual periphery of the rim against the flange a and b and is provided with
recesses.c in its internal periphery into which fits the projections a' of the web A.
The external periphery of the ring C is provided with a series of recesses c¹ into
which fit the projections on the interior periphery of the web B. The
connection of the ring to the webs as above described serves to very effectually
prevent the rim from slipping upon the hub portion..
62 is a retaining ring, which is secured on the face of the web by bolts D, which
pass through the ring, the ring C and the flange and alternately through
simply the ring & and the web B¹.
43 is a retaining ring, which is secured to the face of the web A by bolts E.
which pass alternately through the rubber ring C and flange a, and the ring a² and
web A alone. By means of the permanent flanges, removable flanges and bolts
above described 'the two webs A and B are both secured to the ring C.and this

page_text: menus of securing serves to allow Line (unorgive fatorany around the entire
periphery.
The rings and a³ are connected together by yielding wires a³, so as to permit
of the passage of an electric current where my wheel is used for electric cars.
The lateral yielding of the wheel is more clearly exhibited in Fig. 5, in which
I show two pairs of wheels secured on their axles F, which are suitably secured to
a truck G. The rails of the track are designated by the letters H and show a
curve. The dotted lines of the wheels. show. the position, which the ordinary solid
wheels assume when passing around a curve. The full lines exhibit the position
which my wheels assume when passing around a curve, the wheels at the left hand
side of the figure being in section to exhibit the bending or yielding of the ring C
between the hub web A¹ and the rim web B'. By this yielding of the ring it will
be clearly understood that the plane passing through the flange b of the rim will
be kept more nearly parallel with the groove h in the rail, so that the impinging of
the flange upon the rail as it passes around the curve will be reduced to a minimum
and thereby effectually prevent friction and the consequent rapid wearing out of the
flanges of the wheels and the curved rails which are necessarily more expensive
than the straight to manufacture. A great economy is thus effected.
It will be noticed in my invention that the centre or hub portion and web need
not be renewed but it is only necessary to separate the rim portion when it becomes
worn and re-place it alone. By providing the ring C between the hub portion' and
rim portion & cushion is formed and the rattle and noise of the wheels is also
reduced considerably. .
Having now particularly described and ascertained the nature of my said inven
tion, and in what manner the same is to be performed, 1 declare that what I
claim is:
"
.
1.. In a car wheel the combination with the hub portion and web, of the rim and
web and yielding meaus for securing the exterior of the hub web to the interior of
the rim wob.as and for the purpose specified.
2. In a car wheel the combination with the hub portion and web, of the rim and
web and a yielding rubber ring fitting between the exterior periphery of the hub
web and the interior periphery of the rim web and means for securing the parts
together as and for the purpose specified..
3. In a car wheel the combination with the hub. portion and web and outwardly
extending flanges formed on the periphery of such hub web, of a rim portion and
web and an inwardly extending flange formed on the interior periphery of the rim
web and a yielding rubber ring and means for securing such ring to the outwardly
and inwardly extending flanges as and for the purpose specified.
4. In a car wheel the combination with the hub portion and web and outwardly
extending flange formed on the periphery of such hub web, of a rim portion and
web and an inwardly extending flange fornied on the interior periphery of the rim
web and a yielding rubber ring, retaining rings on the opposite side of the yielding.
ring upon the hub portion and ring portion and bolts extending through the webs,
yielding rings and retaining rings as and for the purpose specified.
5. The combination with the hub portion and web and a series of projections on
the exterior periphery of the hub web portion, of the rim portion and web and
projections formed on the interior periphery of the web and the yielding rubber
ring provided with corresponding recesses both on the interior and exterior to fit
the interior and exterior recesses of the hub web and rim web portions respectively
and means for securing the portions together as and for. the purpose specified.
6. The combination with the hub and web, of the rim and web, yielding means
for securing them together and electrical means for connecting the rim to the hub
as and for the purpose specified.
7. The combination with the hub web of the rim and web, yielding means for
securing them, together and wires a³ extending between the hub, web and rim
portions as and for the purpose specified.

page_text: 8. In a car wheel the combination with the hub portion and web, of the rim
and web formed separately therefrom and suitably connected thereto, and means
for permitting an angular planary deviation of the face of the rim portion from the
face of the web portion as and for the purpose specified.
