PROVISIONAL SPECIFICATION.
An Improved Pneumatic Hub for the Wheels of Cycles and other
Vehicles.
FREDERICK GEORGE SMITH, 32, Sun Street, Birmingham, Stationer and News
agent and JAMES CHARLES RHODES, of the "Barn and Barrel," Berrington Road,
Tenbury, Beer Retailer, do hereby declare the nature of this invention to be as
follows:-
It consists of a hub "A" with two flanges "B," each flange being secured
to the hub "A" a distance from each other. Between these flanges is fitted a
hollow cylindrical hub "C" which is free to move about at will and on the outer
part of the cylindrical hub "C" are flanges or projections "D" to secure the
spokes thereto. There is also a valve "E" secured to the outer part of the before
mentioned cylindrical hub "C" which is connected to a concave rubber tube "F."
Between the inner & outer hub "A" & "C" we place two concave hollow rubber
tubes "F" & "G" the tubes being made to fit the hubs "A" & "C," & the
tubes at the point of contact are jointed securely together. There are pas-
sages "H" left in places at the point of contact so that communication can take
place from one to the other of them. The before named valve "E" communicates.
with these hollow tubes "F" & "G." When these tubes "F" & "G"
"
are inflated
with air the outer tube F" becomes tightly pressed against the internal part
of the cylindrical hub " C" the inner one G" becoming tightly pressed against
the flanges "A" & "B" of the inner tube thereby securing the outer & inner
hubs together, but to thoroughly ensure the security of the two hubs "A" & "B"
together we connect the hubs A" & "B" together by means of a spring one end
of the spring being secured to the outer part of the inner hub "A" the other end
being connected to the inner part of the outer hub “C” the spring passing through
and partially around the internal part of the concave tubes F" & "G" as before
illustrated.

We, FREDERICK GEORGE SMITII, of 32 Sun Street, Birmingham, in the County
of Warwick, Newsagent and Stationer and JAMES CHARLES RHODES, of Berrington
TDi Q71

page_text: Road, Tenbury, in the County of Worcester, Beer Retailer, 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 consists as hereinafter described of an improved pneumatic hub
for the wheels of cycles and other road vehicles and has for its object to provide
a suitable means of reducing the vibration caused to such wheels.
To enable our invention being clearly understood we will describe it by reference
to the accompanying drawings of which Figure 1 is a side elevation of our pneu-
matic hub and Figure 2 a section through the same.
The hub A runs freely upon the spindle C by means of the ballbearings D, D,
and is provided with the two collars B, B, one of which is part of the hub A the
other being screwed up against the shoulder O. Between these collars we fit
an external hub E of much larger diameter than the hub A. We construct a
rubber pouch or double tube F with open air passage V, which is inserted in
the outer hub E and fits around the hub A, being inflated through the valve G.
After being inflated the tube is forced against, the inner and outer hubs A and E
the corners of the pouch being forced against, the flanges B and thus. constitutes
an airchamber, forming a yielding,, or resilient cushion for the cycle or other
wheel to ride upon.
The tube is held in position by the clips H, H, H, H.
To insure the hubs A and E being held together we employ a spring I one end
of which is secured to the outer part of the inner hub A and the other end to the
inner part of the outside hub E.
The spring I passes through and partially around the internal part of the pouch
or tube Faforesaid.
The hub E is provided with the flanges k to which are secured the wheel spokes.
If used with our hub a solid tyred wheel will obviously run as easily as a
pneumatic tyre as the vibration is prevented and the whole wheel will be supported
on an air cushion..
Having now particularly described and ascertained the nature of our invention
and in what manner the same is to be performed we declare that what we
claim is:
i
,
1. The improved pneumatic hub substantially as herein described consisting
of the outer hub E and inner hub A, also the air tube or pouch F.
2. In combination with the hub A and ball bearings D, D, the external hub E
fitted to the hub A and supported by the inflated air tube F substantially as
described and illustrated and for the purpose set forth.
Dated this 26th day of September 1898.
