Architect and Surveyor, do hereby declare the nature of this invention to be as
follows:-
My invention has reference to prior application for Letters Patent applied for
by me ou the 3rd day of October A.D..1894, No. 18,694 for wheels to be used for
cycles, vehicles, pulleys, or other purposes where a yielding wheel is required.
My present invention comprises an improved method or means of constructing
or building up the two or more parts or portions of the wheel, referred to in my
prior Patent No. 18,694 or 1 may build up the wheel in more parts than there
shewn, that is, I might duplicate or multiply the principle or the idea there
defined.
And also for an improved means of obtaining or gaining friction between the
two or more disconnected parts or portions of the wheel and the yielding rings or
tubes of rubber or other material.
And also for an improved means of fixing and of placing the rubber tubes or
rings.
I might also employ a new arrangement of one, two, three or more yielding
rings or tubes arranged and placed in any suitable position between the centre or
axle of the wheel and the outer rim or felloe of the wheel, or I may place these
yielding rings or tubes outside the spokes and felloe with their enclosing covers or
with an additional felloe if thought desirable.
According to my invention the hub of the wheel may or may not be made secure
to the axlo and the wheel would also be made in two or more parts, which would
be in loose connection with each other, there would be a convex or concave or any
other suitably shaped space or spaces between these two or more parts, which the
rubber rings or tubes would fill up, or only partially fill up; these yielding rings
or tubes may be solid rubber ringe or cushion tubes or pneumatic tubes, or any
other suitably inflated tubes, or any arrangement of yielding material or even a
series of rubber balls may be employed and the rings or tubes may be of round,
square, or any other shape in cross section and also of any size.

1, WILLIAM IVES, of 17, Milton Place, Halifax, in the County of York,
Architect and Surveyor, 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 has reference to prior application for Letters Patent granted to

page_text: me bearing, date, the 3rd day of October A.D. 1894, No. 18,694, and also prior
Application on the 6th day of September A.D. 1895, No. 16,673 for wheels to be
used for oycles, vehicles pulleys or other purposes where a yielding wheel is
required.
My present invention comprises an improved method or means of constructing
or building up the two or more parts or portions of the wheel, referred to in my
prior Patent No. 18,694 and Application No. 16673 or I may build up the wheel in
more parts than there shewn, that is, I might duplicate or multiply the principle
or the idea there defined.
And also for an improved means of obtaining or gaining friction between the
two or more disconnected parts or portions of the wheel and the yielding rings or
tubes of rubber or other material:
And also for an improved means of fixing and of placing the rubber tubes or
rings.
I might also employ a new arrangement of one, two, three or more yielding
rings or tubes arranged and placed in any suitable position between the centre or
axle of the wheel and the outer rim or felloe of the wheel, or I may place these
yielding rings or tubes with their enclosing covers or with an additional felloe if
thought desirable outside the spokes and felloe.
According to my invention the hub of the wheel may or may not be made secure
to the axle, and the wheel made in two or more parts, in loose connection with each
other, there being a convex or concave or any other suitably shaped space or
spaces between these two or more parts which the rubber rings or tubes would fill
up, er only partially fill up. These yielding rings or tubes inay be solid rubber
rings or cushion tubes or pneumatic tubes, or any other suitably inflated tubes, or
any arrangement of yielding material or even a series of rubber balls may be
employed and the rings or tubes may be of round, square, or any other shape in
cross section and also of any size.
For the purpose of fully describing and ascertaining my said invention I, have
bereunto annexed two sheets of drawings forming a part of this specification, in
which-
Fig. 1 is a sectional elevation, taken on line 1-2 of Fig. 2, of a flexible hub or
wheel constructed on the lines of my invention;
Fig. 2 is a side elevation of Fig. 1 ;
Fig. 3 is a plan of a part of Fig. 2;
Fig. 4 is a detail hereinafter referred to; and
Fig. 5 is a sectional elevation of a modified construction of hub or wheel.
Referring firstly to Figs. 1 to 4, letters A and B.represent two separate parts
of which the hub is constructed, the part A being attached to, or mounted loosely
on, the axle C and the sides thereof arranged on the outside of part B while the
part B is attached to the spokes F of the wheel. In a modified arrangement these
sides of part A may be arranged inside of part B, that is, reversing the order
shewn. The part A has side discs, plates or arms A' bolted or rivetted or
otherwise attached thereto, to connect and strengthen and give rigidity to a
rim A, which rim is attached to the parts A¹ and forms a part of the inner portion
of wheel A. On the outer and inner surfaces of this rim A' are formed teeth or
projections A, as shewn for preventing slipping; or instead of teeth or projections,
the said rim may be 'corrugated as shewn at Fig. 4, or it may be perforated, or
studs may be used or other means employed.
197
The part B is constructed with, two bands or rims B', B³, made of metal or other
material arranged concentrically with the rim A' of part A which occupies a
position intermediate of said bands or rims B¹, B³, which, bands, or rims B¹_and_B³
are connected together by side discs, plates or arms B. Into the spaces,left
between the rim A' and the rims B1, B2, are inserted yielding rings or tubes D
and E, these being either solid, hollow, or pneumatic, or other suitably inflated
tubes and of any desired or preferred shape in cross section.
As will be understood from my previous Patent No. 18,694, and Application

page_text: No. 16,673 hereinbefore referred to, the weight placed upon the axle C will be
borne by the downward pressure of the rim A' of part A, (which must necessarily
move with the axle) upon the upper or outer part of the inner tube or ring E
above the axle and on the upper or inner part of the outer tube or ring D below
the axle, which tubes or rings will yield to said pressure or weight and return to
their normal condition immediately the pressure is removed. In like manner, any
movement of the wheel itself out of centre with the axle, as in riding over an
obstruction, will be resisted or cushioned by the pressure of the bands or rima B', B³,
which will compress or squeeze the tubes or rings D, E, at opposite sides of the
hub or axle of the wheel.
The yielding tubes or rings D, E, may be cemented or attached in any other
suitable manner, to the hands or rims B1, B2, and the teeth, corrugations, perfora-
tions or other devices on the rim A³ are provided for the purpose of preventing
the tubes slipping or for obtaining or gaining the requisite amount of friction so
that the parts A and B of the hub shall rotate together, and liability of the part A
turning or slipping around independently of part B is thereby reduced to a
minimum.
In a modified arrangement the tubes may be fixed to the part A' and, the
rims B1, B2, may be corrugated to gain the friction referred to.
I might also if thought advisable attach the tubes to both the separate parts of
wheel.
.
Should it be necessary to increase the friction, I may arrange the yielding tubes
or rings so that on being compressed, the sides thereof would expand into the
openings in the sides of the part A or against said sides, which may be corrugated
thereby obtaining additional friction laterally by means of the tubes or rings. At
each side of the rim A¹ of the part A. I form or leave openings or spaces A*, as
shewn clearly in plan of part A at Fig. 3, which plan shews the toothed periphery
and also on the right hand side of Fig. 2 where a portion of the near disc A¹ has
been broken off. Through these said openings A pass the arms B of the side
discs or plates connecting the two bands or rims B', B³, together, such said arms
being free to move up or down therein, or backward and forward as would be the
case if there were independent rotation of part A or part B. The inner rim B* of
part B may have an annular flunge B4 as shewn thereon, which would enter a
groove or guide A as shewn on the part A if this should be considered necessary
and which would guide the part B vertically and maintain it in a perpendicular
position.
Although I have shewn the flexible or yielding portion of the-wheel as forming
the hub or occupying a position between the axle and the felloe, it will be under-
stood that it may be applied outside the ordinary folloe or spokes of the wheel
precisely in the same manner as it is fitted on the axle, the spokes F shewn
attached to the outer rim or band B' in this case being omitted. Or, if required,
I may apply my improvements both to the outside of the spokes and felloe of the
wheel, and also to the hub of said wheel.
-
In Fig. 5 a similar construction of bub or wheel is shewn comprising the two
parts A, B, but in this case two rubber or yielding tubes or rings D, D¹, are
placed between the outer band or rim B' of part B and the rim A³ of part A, and
two yielding rings or tubes E, E', between the said rim A' and the inner rim or
band B2 of part B. Each pair of said tubes or rings bear one against the other,
and may be corrugated or otherwise prepared to gain friction. One tube or
ring D, E, of each pair may be moulded as shewn whereby it will have two points
of contact with its companion tube or ring and increase friction, or any other
suitable shape or form of tubes may be adopted. The tubes or rings if pneumatic
or inflated may be secured to the parts of the hub by their outer coverings S
somewhat as shewn, or they may be attached by any other suitable manner or
means. I provide a space G between the two sets of tubes or rings to accommodate
the air valves and to afford room for the introduction from outside of a pump or
inflator to inflate the two central tubes.

page_text: I do not confine myself to the precise construction of flexible hub or wheel
herein shewn and described, as the same may be varied somewhat without
departing from the essential feature of my invention, namely, a flexible hub or
wheel constructed of two parts, one connected with the axle and the other with the
spokes, each being movable in a vertical plane independently of the other against
the resistance of pneumatic, inflated, or other suitable description of yielding or
elastic tubes or rings interposed between bearing surfaces on each said part. Nor
do I limit myself to the number or order of arrangement of yielding tubes or rings
(or method of fixing same) herein set forth, as they may be added to or taken
from, according to requirements and disposed and arranged in such positions even
eccentrically or out of centre with the axle as will give the best results. It will
be obvious that the construction of flexible hub or wheel as herein described, may
be adopted or followed in respect of the several constructions and arrangements
shewn and described in my said prior Patent No. 18,694" and Application
No.. 16,673⁹
Having now particularly described and ascertained the nature of my said inven-
tion and in what mauner the same is to be performed; I declare that what I
claim is:-
Firstly. The improved construction, arrangement, and combination of flexible
hub or wheel substantially as herein shewn and described with reference to
Figs. 1 to 4.
Secondly. The improved construction, arrangement, and combination of flexible
hub or wheel having flexible rings or inflated tubes working in pairs vertically
in separate chambers or parts of the hub or wheel, such said rings or tubes
bearing one against the other, substantially as shewn and described with reference
to Fig. 5.
Thirdly. The combination with the improved construction, arrangement, and
combination of flexible hub or wheel herein described, of the means or method of
gaining or increasing friction between the separate parts of the hub or wheel by
allowing lateral expansion of the yielding tubes, substantially as set forth in the
specification.
Dated this 14th day of September 1896.
