Improvements in and connected with Wheel Tyres.
1, WILLIAM ROBERT LAKE, of the firm of Haseltine Lake & Co. Patent
Agents 45 Southampton Building, in the County of Middlesex, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
Statement:-
My invention relates to elastic inflatable wheel tires used on bicycles or other
vehicles.
The object of my invention is to produce an efficient simple and comparatively
cheap vehicle tire, composed of an inflatable inner tube and an outer tire adapted
to be held by a metallic felly.
The invention consists of providing a metal felly composed of one or more
parts with an elastic inflatable tire adapted to be held in the metal tire by scarf
joints.
The invention further consists of a metal felly composed of one or more parts
and having an elastic or resilient tire portion adapted to be held by the metallic
felly by scarf joints and inflated by an auxiliary tube located within said elastic
or resilient tire.
The invention further consists of a flexible tire composed of a Hat piece or
sheet of elastic material having a thickened tread portion and on each edge
thereof a rabbeted portion forming one member of a scarf joint whereof the
other member is formed on the metal felly, which is especially adapted to receive
and hold the elastic tire, and which elastic tire is supported and strengthened by
an inner auxiliary and highly elastic air tube.
The invention further consists of the improvement herein set forth and illustrated
in the drawings, in which
Fig. 1, is n view illustrating a cross-section and elevation of my improved tire,
in which the metal felly is composed of two parts for supporting the inflatable
tire, and
Fig. 2, is a similar view showing the metal felly composed of one part.
Referring now to the drawings for a further description of my invention, A is a
metal felly made either in two parts riveted or otherwise fastened together as shown
in Fig. 1, or it may be formed in one part as shown in Fig. 2; this metal felly
has substantially a Y-shaped cross-section and the V-shaped cavity a thereof is
provided with rabbeted projections a' and a forming one member of scarf joints
hereinafter more fully described. The upper edges of the Y-shaped metal
felly are rounded off and are either hollow as shown in Fig. 1, or solid as in
Fig. 2, and serves for a purpose to be described. The web a is provided to
strengthen the metal felly A and may be used as the part to which the spokes
are attached, however, if it is desired, the spokes may be secured to the upper
edges which are very convenient portions for the purpose.
B is a continuous clastic tire being made of a Hat or suitably curved endless
sheet and provided with a thickened tread portion and rabbeted projections b
and forming the other members of the scarf joints of the tire with the felly A,
and these projections and terminate in the wedge shaped edges and 6º.
The tread portion & may, if desired, be provided with cross ribs &³ or corrugations
to avoid slipping of the tire on slippery roadways.
C is an inner continuous auxiliary air tube composed of highly elastic material
which is adapted for being inflated by air or other agent by means of a pump not

page_text: shown and the well known nozzle and stop cock c, and which nozzle may be
fastened to the felly A, the tire B, and auxiliary tube in any good manner which
will prevent leakage of the auxiliary tube Cat this particular point, it may be
mentioned however that the auxiliary tube C may be cemented to the flap or
portion of the tire B at this particular point, for the
purpose stated.
The tire B may be applied to the felly A very readily in the following manner:
The nozzle e being fastened in position on the metal felly A and the tire Band
auxiliary air tube fastened to each other and to the nozzle c and felly A, the tire B
is caused to envelop the auxiliary tube C and pressed in position so that the
rabbeted portions a¹ and and a² and and the wedge shaped edges and
engage with each other. An inflating agent may now be forced into the interior of
the tube which expands and lays close to the walls of the tire 13 to support the
same, it will be understood that by inflating the tube C and giving and maintaining
the tire B in the requisite shape the rabbeted member constituting the scarf joint
of the tire 13 and felly A engage very firmly and the wedge shaped edges and 5
are pressed together by the said inflation of the tube Cas that the sheet tire B
will form an air tight tube and its air tightness will increase with the pressure
exerted upon the side walls of said tire Bas that even if the inner tube should
become leaky, the tire B itself would form a substitute therefore.
If by any
reason the tube C is mutilated and requires reparation the tire B may be easily
disengaged from the felly A and the tube C be exposed at the part desired by
letting out the inflating agent and unlocking the scarf joint between the tire B and
felly A.
If it is desired the inner tube C may be dispensed with, as the tire B of sheet
rubber will form an air tight tube as before stated.
The rounded off edges a³ are provided to prevent cutting of the tire B and to
give a broad bearing surface to the tire. It will be understood by those skilled in
the art to which this invention appertains that slight modifications may be made in
the shape of the felly and tire as well as in the location of the air nozzle C, without
departing from the spirit of the invention.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent I declare that what I claim is:-
1. An inflatable tire composed of a flat endless sheet of elastic material adapted
to be sprung into a V shaped felly provided with projections adapted to engage
similar projections on the flat endless elastic sheet to form an air tight continuous
inflatable tire substantially as and for the purposes set forth.
2. An inflatable tire composed of a flat endless sheet of elastic material having
bevelled off edges said edges provided with projections adapted to engage similar
projections on a V shaped metal tire to form a continuous air tight inflatable tire
substantially as and for the purposes set forth.
3. An inflatable tire composed of a flat endless sheet of elastic material adapted
to be sprung into a V shaped metal felly and held therein by scarf joints formed
by projections or spurs on the tire and felly, so as to form an air tight continuous
tube and an inflatable tube located within said tire substantially as and for the
purposes set forth.
