Improvements in and relating to Pneumatic Tyres.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, do hereby declare tho
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:-
The present invention relates to a wheel rim and tire including the means for
securing the tire to the rim, the object being to afford a strong and easily mani-
pulated fastening device for heavy pneumatic tires to be used with large and
heavy vehicles such as motor carriages.
In accordance with the invention, the fastening devices for the tire when in
position also partially constitute the support for the tire, the said devices extending
laterally from the rim proper which receives the spokes and being shaped to
conform to and support that part of the tire which projects beyond the sides of
the rim and is not directly supported by said rim, the said tire, however, extending
substantially completely across the face of the rim so that the tire is adequately
supported and the air tube unbroken and complete.
In carrying out the invention, the rim proper is preferably made of wood and
the fastening devices of metal, the said fastening devices having lateral extensions
to fit the curve of the tire and being adapted to be clamped to the sides of the rim
proper as by bolts extending through the said fastening devices and the rim
proper and secured by nuts. It is obvious, however, that the rim proper may
be also made of metal, it not being essential to the invention that the said parts
should be of any particular materials.
Fig. 1 is a side elevation of a portion of a wheel rim having a tire attached
thereto in accordance with the invention; Fig. 2 a transverse section of the same;
and Fig. 3 a modification showing the tire permanently secured to the fastening
devices instead of clamped between the same and the rim, an inner tube being
shown in this instance and the outer tube having its edges brought together to
support the same.
The rim as a whole may be described as consisting of the rim proper a, which
is adapted to receive the spokes of the wheel, not herein shown, and the fastening
devices which serve to secure the tire c to the rim, the said fastening devices
when in position having lateral curved extensions 62 to form in conjunction with
the rim proper a, a channel to conform to and support the rounded or cylindrical
surface of the tire.
The fastening devices 6 may be annular and continuous if desired, but are
herein shown as made in sections, each section being secured to the rim proper a
by means of the transverse bolts d which extend through the main portions of
said fastening device and through suitable openings in the rim, as best shown in
Figures 2 and 3, and secured in position by means of nuts &

page_text: As shown in Figure 2 the tire c is of the single tube type and is shown as
having extensions or flaps 4 projecting from its outer surface and adapted to lio
along the sides of the wheel rim a, while the tire itself extends across and is
supported on the face of the rim a. The main portions of the fastening devices b
are then drawn into contact with the outside of the said extensions c, so that the
said extensions are clamped between the sides of the rim and the said fastening
devices, as shown. With this construction it is desirable to provide the rim
with a channel a² at each side thereof to receive the ribs or projections (40 formed
along the inner surface of the flaps so that when the tire is clamped in position
it cannot be pulled out of the channel formed by the rim and the fastening devices.
To make the rim uniform in shape after the tire is fastened thereto and also
to provide a proper support for the ends of the tire-flaps ct and for the fastening
devices b, the said rim is shown as provided with shoulders a³ on which the fasten-
ing devices b rest, the channels a² being formed in the sides of that portion of the
rim which projects above the said shoulders which portion affords, so to speak, a
supporting tongue for the body of the tire, the said tongue being strengthened
by the fastening devices which are clamped thereto, while the body of the rim
below the said fastening devices has sufficient sectional area to afford the neces-
sary strength where the spokes are fastened, the said body being preferably curved
as shown along its under or inner surface.
When a tire of the inner tube type is to be used, as shown in Figure 3, the
outer projecting tube 20 may be permanently secured to the fastening devices
instead of clamped thereto, the said outer tube 20 in this instance being open
along its under side and riveted or otherwise fastened along the edges of said
opening to the fastening devices b, the rivets 620 being herein shown as extending
through the said edges of the tire and the wings or extensions 3 of the fastening
device, so that they are permanently secured thereto and held in position when
the fastening devices are secured to the rim a. The edges of the outer tube as
shown extend across the rim and meet so that they afford a proper support for
the inner tube 3, the whole tire being substantially continuous and extending
completely across the rim.
It will be seen from the foregoing description that the wheel rim and fastening
devices constructed in accordance with the invention afford a very efficient support
and connection for the tire as well as one which is readily applied and easily
removed if repairs are needed. Further than this, the rim proper and fastening
devices together constitute a very strong wheel construction and when wood is
used for the rim proper, a construction which is as light as is practicable for heavy
vehicles for which the invention is especially adapted.
It is not intended to limit the invention to the specific construction herein shown
and described, since modifications may obviously be made without departing from
the invention.
Having now particularly described and ascertained the nature of my said
invention 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. The combination with a wheel rim, of a tire extending around the outer
face thereof, the surface of said tire lying in contact with the said face and
extending across the same, and fastening devices comprising plates or strips of
suitable material provided with lateral extensions curved to conform to and
support the surface of the tire where it projects beyond the sides of the rim so as to
afford in conjunction with the said rim a channel to laterally support the tire,
and means for securing said fastening devices to the opposite, sides of the rim,
substantially as and for the purpose described.
3. The combination with a wheel rim, of a pneumatic tire comprising a con-
tinuous tube extending around and supported upon the outer face of said rim,
flaps or extensions from the outer surface of the said tire separated from each 5

page_text: other by a space substantially equal to the width of the said face across which the
said tire extends between said flaps, fastening devices comprising plates or strips
of suitable material adapted to engage the outer surfaces of the tire flaps and to
be secured to the wheel rim at opposite sides thereof, and lateral extensions from
said fastening devices curved to conform to and support the tire where it projects
laterally beyond the said wheel rim, substantially as described.
