AN IMPROVED COMBINATION WHEEL
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I BENJAMIN POOLE of Bristol Street Birmingham in the County of Warwick
Wood Turner, do hereby declare the nature of the said invention for "AN
IMPROVED COMBINATION WHEEL" to be as follows that is to say:-
My Invention has for its object "An Improved Combination Wheel" which is
substantial and firm in its body without being too rigid and is well tied together in
its various parts and yet elastic on the tread It is designed for perambulator and
other similar wheels for road carriages and is calculated to withstand very hard
wear and tear.
My wheel is composed as follows: The outer tread of the wheel is an india
rubber or other elastic band round on the outer face or tread but flat at the back
where it is embedded into a channel iron trough or bed. The body of the wheel
is composed of wood the boss having a considerable groove at the centre of its
depth and the wood arms opening out from the felloes which form the inner rim or
seat of the channel iron ring.
In making these wheels extra care must be taken to have the felloes perfectly
dry before the channel ring is shrunk on. The ring may be fastened through each
felloe by a strong screw and then the india rubber or other elastic ring is cemented
into the channel groove. The rings are rather more than a semi circle in cross
section.
COMPLETE SPECIFICATION.
I BENJAMIN POOLE care of Barkers Patent Offices 77 Colmore Row Birmingham
and 23 Bristol Street Birmingham in the County of Warwick Wood Turner do
hereby declare the nature of the said invention for "AN IMPROVED COMBINATION
WHEEL" and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement to be as follows that
is to say :-
My invention has for its object "An Improved Combination Wheel" which is
substantial and firm in its body without being too rigid and is well tied together

page_text: in its various parts and yet elastic on the tread-It is designed for perambulators
and other similar wheels for road carriages and is calculated to withstand very
hard wear and tear.
My wheel is composed as follows: The outer trend of the wheel is an india
rubber or other elastic band round on the outer face or tread but flat at the back
where it is embedded into a channel iron trough or bed. The body of the wheel is
composed of wood the boss having a considerable groove at the centre of its depth
and the wood arms opening out from the felloes which form the inner rim or seat
of the channel iron ring.
In making these wheels extra care must be taken to have the felloes perfectly I
dry before the channel ring is shrunk on. The ring may be fastened through each
felloo by a strong screw and then the india rubber or other elastic ring is cemented
into the channel groove. The rings are rather more than a semi circle in cross
section.
In order that my invention may be clearly understood and more easily carried 1
into practice I have appended hereunto a sheet of drawings upon which I have
illustrated my invention.
Figure 1 is a front elevation showing a sufficient part of a wheel in side elevation
to make the invention-clearly-understood.
Figure 2. is an enlarged cross-section-of-the-rim-of-the-wheel on line A. B.
Figure 3 is another similar section Now referring to the drawing C is the
rubber ring or band made of elastic or other soft material to give an easy flexible
tread. D is the channel metal ring which may be of iron, steel or other metal and
E..E-are the felloes of the wheel to receive the said channel ring D which may be
either fastened to the felloes by screws as shown-by-Figure-2-or-by-cement_as_2
shown-by Figure-3...
Of course the proportions and shapes may be greatly varied without departing
-from-the-nature-of-the-invention.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what 3
