COMPLETE SPECIFICATION.
Improvements in the Manufacture of Hubs, Bushes, or the Corre-
sponding Parts of Wheels of Velocipedes, Perambulators, Bath
Chairs, Carriages, and other Vehicles, and for other purposes.
1, ARTHUR JAMES POWELL, of 90 Vassall Road Brixton, in the County of
Surrey, Clerk, 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 consists of the improvements hereinafter described, in the manu
facture of hubs, bushes, or the corresponding parts of wheels, of velocipedes,
perambulators bath chairs, carriages, and other vehicles, and for other purposes,
having reference to the application of a coil or tube, or coils, or tubes, of any
desirable form, consisting of indiarubber canvas, or any other suitable fabric, or
combinations of indiarubber canvas, or any other suitable fabric, or any other
elastic material same being inflated with air, or gas, or balls of any form whatever
either inflated, solid, or otherwise, or a solid coil or tube, or hollow or any other
suitable form, to the hubs, bushes or corresponding parts of wheels of any vehicles,
or in connection with the hubs, bushes, or corresponding parts of wheels of any
vehicles, no matter what they be termed, as hereinafter explained.
The object of my invention is to reduce the vibration in wheeled vehicles, and at
the same time ensure increased speed in travelling, owing to the resilient properties
of the wheel, according to my invention. Reference is to be had to the
accompanying sheet of drawings, forming part of this Specification wherein―
Figure 1. represents the transverse section of the hub, or bush, of a wheel.
Figure 2. shews an end view of the hub or bush.
Figure 3. shews a transverse section of the hub or bush, representing, how I
propose to apply it to the wheels of heavier vehicles, although I do not bind myself
to any particular method, but should use the most suitable.
Figure 4. shews my invention, which could be applied to any part of what is
known as the axle of a vehicle. The same letters of reference, indicate similar
parts in all the figures.
Referring to Figures 1, 2 and 3. A is the bearing pin, or part of axle, whichever
the case may be. B represents the lower or bearing section of the hub or case,
which is composed of metal, or other suitable material, interior of which is shown
concave but I do not bind myself to any particular form, and is attached to the
bearing pin or axle, in the most suitable manner. C. represents the upper section
of hub or case, which is also composed of metal or other suitable material, and
which is shown concave, but I do not bind myself to any particular form. The
upper section of hub or case C. is fixed in position by metal of any desirable
composition or form, but preferably, by ordinary steel spokes, running from it on
either side, or in any other manner, to the rim of the wheel, so as to allow of
sufficient space being left between circular section of hub or case B. and circular
section of hub or case C. for the purposes hereinafter explained.
D represents a very strong lining of cloth, canvas or any other suitable material,
which may have elastic properties, if I desire it, and which surrounds the coil or
tube E. same may be of any desirable form or composition as hereinbefore
explained. Said cloth or canvas lining 1 to be fastened with cement or rivets or
any other method, to the inner parts of B and C or round the exterior parts of B
and C. As will now be seen, this connects in an efficient manner, the lower or
bearing hub or case B to the upper hub or case C. I now by means of a channel,
or duct F inflate, if I desire to use a hollow coil or tube, the coil or tube E with air
or gas, with the result that vibration is reduced. I wish it to be understood, that

page_text: in applying my invention the coil or tube E may be attached to the canvas lining D,
or separate from it.
G represents a strip, or strips, of metal as shown in Figures 1 and 2, or may be
applied as shown in Figure 3. by lengthening the lower or bearing hub or case B,
or the upper section of hub or case C. so that one shall work inside the other and
thereby prevent the oscillation of the wheel from side to side.
I wish it to be understood that any ordinary bearing may be used in the
manufacture and application of my invention, and therefore it is not necessary to
shew any particular one in the accompanying drawings.
In Figure 3. the lower or bearing section of hub or case is shown in two parts,
but this is optional, as I may apply it in one piece or composed of different parts.
In Figure 4 I shew my invention attached to a metal support, but I wish it to be
understood that I do not claim any particular mode of attaching it, but should fix it
to any vehicle, in any way, and to any part, in connection with the axle, which
would pass through the centre at H, at any position between either wheels, and
would thereby ensure much less vibration when travelling.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I.
'claim is =
1. The application of a coil or tube, or coils or tubes, of indiarubber, or any
other elastic material or composition, of any desirable form as hereinbefore
explained, to the hubs, or bushes, or the corresponding parts of wheels, of
velocipedes, carriages, and other vehicles, in the manner as herein before explained,
for the purpose of reducing the vibration of vehicles when travelling, and for other
purposes, as hereinbefore set forth and described.
2. And the original idea of a coil or tube of indiarubber or other elastic material,
or composition, partly surrounded by a hub or case, which in my Specification, I
term, the bearing or lower hub or case B. and the upper section of hub or case C.
to which the spokes are attached, and which will serve as a non vibrating hub or
bush or the corresponding part in wheels of vehicles, or as an attachment to the
hubs or bushes of wheels of vehicles, or as an attachment to vehicles, as herein before
described, by which means vibration will be reduced.
Dated this 23rd day of June 1891.
