PROVISIONAL SPECIFICATION.
Improvements in the Construction of Wheels for Velocipedes and
other Vehicles.
I, HENRY WARRY of No. 3 Birnbeck Terrace Weston-super-Mare in the
County of Somerset Gentleman do hereby declare the nature of this invention to
be as follows :-
To the back of a steel rim intended to receive an india rubber tyre, I attach, also
by its back, a second steel rim of less diameter, but having the opening of its groove
inwards, towards the centre.
In the annular space between the said second steel rim, and a third steel rim
of still less diameter, to which are attached the outer ends of the spokes, or,
appliances for attaching the spokes, of any wheel to be constructed in accordance
with this Specification, I interpose an india rubber ring or fillet, maintained in a
state of tension both radially and circumferentially, by being, throughout its inner
and outer edges, held by, and attached to, the said second and third mentioned steel
rims respectively.
To avoid repetition and confusion, I shall in this Specification refer to the several
steel rims mentioned in the preceding description by a letter.
The first steel rim mentioned as, "intended to receive an india rubber tyre," I
shall refer to as, rim A.
The second steel rim mentioned as, "of less diameter, but having the opening
of its groove inwards, towards the centre," I shall refer to as, rim.B.
The third steel rim mentioned as, "of still less diameter, to which are attached
the outer ends of the spokes," I shall refer to as, rim C.
I shall also refer to the "india rubber ring, or fillet " previously mentioned as,
the fillet.
Rim A, may be of any diameter and section, but should have a certain portion
of its back, or that part to which spokes would ordinarily be fixed, of a plane or
flat surface or section, that it may be more securely attached to rim B.
Rim B, also, should have a similar portion of its back, which in this rim is on its
outer circumference, of similar form to that mentioned above, the remainder being
of any sectional form suited to the purpose it is to serve.
Rims A and B, are to be of such diameter respectively, that when rim B is
placed within rim A, the two rims lying in the same plane, the flat portion of their
backs shall be in contact throughout.
Rims A and B, are now to be firmly united back to back by rivetting, and
brazing.
Rim C, may be of any suitable section. To this rim spokes may be attached, or
screwed nipples, or other devices for holding or attaching spokes. This rim may
be of any suitable diameter, so that when placed within the combination produced
by the union of rims A and B, and concentrically, and lying in the same plane
with the said combination, there shall be an annular space left between rim C and
rim B.
Also
In and throughout the above mentioned annular space, I place the fillet, which
is a ring or band of india rubber, of suitable size, section, quality, and composition,
to be firmly attached and secured by and throughout its outer edge or circumference,
to the rim adjacent to that edge or circumference, that is to say, to rim B.
in like manner by its inner edge or circumference, to rim C; the several attachments
being effected by causing the edges or sides of the grooves of rims B and C respec-
ively, to press, clasp, grip, and hold the edges or circumferences of the fillet.
The fillet is to be of such dimensions, that when attached to rims B and C, in

page_text: the manner above mentioned, there shall be produced and maintained throughout
its substance, a state or condition of tension both radially and circumferentially,
the elastic force in the fillet, acting in the direction of the radius chiefly.
The completion of any wheel constructed in accordance with this Specification,
may be effected, by attaching the inner ends of its spokes, to any arrangement of
hubs, axle, or bearings, or other appliances commonly used or suitable for such
purpose.
COMPLETE SPECIFICATION.
Improvements in the Construction of Wheels for Velocipedes and
other Vehicles.
I HENRY WARRY of No. 3 Birnbeck Terrace Weston-super-Mare in the County
of Somerset Gentleman do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
My invention relates to certain improvements in the construction of wheels
for velocipedes and other vehicles, and has for its object the attainment of
perfect elasticity in action, with the minimum of weight cost and liability in
Herangement.
In carrying out my invention I proceed as follows.: —
To the back of a steel,rim intended to receive an india rubber tyre I attach by
its back a second steel rim of less diameter but having the opening of its,groove
inwards towards the centre or hub of the wheel.
In the annular, space between the said second steel rim and a third steel rim of
still less diameter and to which are attached the outer ends of the spokes or
appliances for attaching the spokes of any wheel constructed according to my
invention. I interpose an india rubber or other suitable elastic ring maintained in
a state of tension both radially and circumferentially, by being held throughout its
inner and outer edges and attached to the before mentioned second and-third
steel rims.
In order that my invention may be more clearly understood I have appended
the accompanying sheet of drawings in which Fig. 1 is a section through the three
rims shewing the manner of attaching the india rubber or other elastic "fillet,"
and Fig. 2 is a side elevation of a whole wheel and Fig. 3 is a-sectional view.of.a
modification.
The first or couter steel rim. A. is adapted to receive an india rubber or other
elastic tyre B and secured to same in the ordinary manner, within said rim A I
arrange a second rim C with its groove towards the centre or hub of the wheelsand
the flat portion of its back or outer diameter in contact with the flat part of the
back or inner diameter of the first rim A-in which position-they are firmly-united
by rivets and by brazing or other suitable method.
lmay also employ instead of the before mentioned combination (A and C, a steel
rim, having a section similar to that I have shewn by Fig. 3.adapted to carry the
tyre B and also to receive and hold the outer incumferential edge of the fillet G,
the attachment of the fillet being effected in the same manner as described .for
rims C and D.
T
The third steel rim D is secured to the hub E by the spokes F and is of smaller
diameter than the before mentioned second rim C so that when placed concentrically
within the combination rim A and C and lying in the same plane with the said
combination rim, there is an annular-space in which I, place the india rubber or
other elastic "fillet " G which may be of any suitable size section and quality, and
firmly secured through its outer and inner circumferential edges to the second
rim and third rim D. respectively by swaging the sides of the rims C -and-Drover

page_text: the swelled circular or other shaped part Ḥ of the "fillet" G in such a manner
that it will not easily become detached.
In the fillet G of a wheel made according to my invention as hereinbefore
described, there is produced and maintained throughout its substance a state of
tension both radially and circumferentially, the elastic force acting in the direction
of the radius chiefly, and at that part of the wheel that is furthest from its point
of contact with the ground. I may if necessary introduce a core into the
swelled or beaded part of the fillet Ġ to prevent it from being pulled away from
the rims C and D.
.
Said core may be made of a harder description of rubber, of cord, or any
material suited to the purpose and may be of elliptical, circular, or any suitable
section.
From the foregoing description it will be seen that I am enabled to employ a
hard composition tyre, or what is commonly called a solid rubber tyre, in contact
with the ground, and yet obtain all the elasticity and freedom from vibration and
jolt usual to machines fitted with pneumatic tyres.
Although I have described and shewn in the annexed drawings my invention as
applied to the wheel of a bicycle or tricycle; I wish it to be understood that it may
be applied to wheels other than those before mentioned.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is:-
First. In a wheel for vehicles, the employment of a fillet or diaphragm G with
cores I, with grooved rims C and D and outer tyre B substantially as herein
described and shewn by Figures 1 and 2 of the drawings hereto appended.
Second. In a wheel for vehicles, the construction and use of a rim A, Figure 3,
in combination with a cored diaphragm G substantially as herein described and
shewn.
Third. In a wheel for vehicles, the employment of an elastic diaphragm G with
cores I, in combination with an outer grooved rim C and inner grooved rim D sub-
stantially as herein described and shewn by the drawings.
Fourth. In a wheel for vehicles, the employment of a fillet or diaphragm G
with cores II substantially as herein described and shewn by the appended
drawings.
