PROVISIONAL SPECIFICATION.
Improved Method of and Means for Securing Cycle and other Tyres
to Wheels.
I, EDWARD GOODMAN SHEWARD, of Eversholt Lodge, Coventry Park,
Streatham, Surrey, Gentleman, do hereby declare the nature of this invention to
be as follows :—
This invention relates to the construction and employment of two ring shaped
appliances, one as an inner rim to a wheel, and the other as a liner to the foregoing
and to the tyre, the edges of which are clamped between them, either by screw
nipples, such as are used for adjustment of spokes when trueing up a wheel, or by
other means, such as rivets or other fasteners.
The invention of the double ring appliances is applicable to ordinary flat rubber
tyres, to pneumatic tyre covers, and to others, also to steel, or ribband tyres.
In some cases, the ring like appliances, or one of them only may be grooved or
kinked for a bead or edge of the tyre or the cover to lodge in.

COMPLETE SPECIFICATION.
Improved Method of and Means for Securing Cycle and other Tyres
to Wheels.
I, EDWARD GOODMAN SHEWARD, of Eversholt Lodge, Coventry Park.
Streatham, Surrey, Gentleman, 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 :-
This invention relates to the construction and employment of two concave or
convex ring shaped appliances, one as a rim to a wheel, and the other as a liner,
either inside or outside to the foregoing rim and to the tyre, the edges of which are
clamped between the rim and the liner, either by a nut and screwed thread upon
the usual nipples used to hold and adjust the spokes in tangent or straight spoke
wheels, or by other means, such as bolts and nuts, or other fasteners which may be
passed through the two rims, either from the inside or outside, clamping the two
rims together.
The outside or inside liner is made either a solid ring or in two or more segments
with or without tapped ends, or the liner is cut through at any point on its
circumference.
The invention of the double ring appliances is applicable to ordinary flat or
moulded rubber tyres, to pneumatic tyres, and covers, also to flexible steel tyres, or
tyres of any ductile material.
In some cases, the edges of the ring like appliances, or one of them only may be
bulbed, or grooved, or kinked, making a bead for the edge of the tyre rim, or liner,
or the cover to lodge in.
My invention will be clearly understood by the examples shown on the annexed
drawings.
Figure 1 is a sectional elevation of a rubber tyre composed of a moulded
strip or ring A having two wings or edges B, B, clamped between and by the

page_text: edges C, C, of the two ring shaped appliances, rim D and liner D¹, by means
of externally screwed nipples E, one only being shown. The nipple E is screw
threaded on the exterior for the reception of a nut F, by turning which on the
nipple E, the two ring shaped appliances D, D', are drawn together, or nearly
into contact to clamp the wings B, B, of the rubber tyre A (after being pushed
in) to fix the tyre A in place. G is one of the spokes screw threaded, or bull-
headed in the nipple E in the usual manner.
Figure 2 is a sectional elevation of a tyre A composed of a steel, or other metal
band with the side edges turned inwardly for engaging between the two ring shaped
appliances D, D, and being nipped firmly together by the nut F on the outside
threaded nipple E as in the previous figure.
Figure 3 is a sectional elevation of a pneumatic or like tube H nearly surrounded
by a cover A constituting the tyre, the ends of which are tucked in between the
two ring like appliances D, D', and clamped by the nut F on the nipple E, a washer I
being employed, which is made more concave than the liner D', so that the nut F,
when screwed against the washer I, may press more firmly upon the edges of the
liner and clamp the rubber tighter.
Figures 4 and 5 illustrate a pneumatic tube tyre arrangement, in which the
nipples act upon the rim D' only for trueing up the wheel in the usual manner, the
liner D, as represented in the sectional view, Figure 5, being formed with a scarf
joint with overlapping ends at J, the said ends being drawn together by the screw
bolt K, through the lugs L, L, fastened to the liner D, which project through
slots M arranged in the rim D¹.
Figure 6 shows the rim D of double or hollow formation suitable to balloon tyres,
the flat portion having slot holes, like as in shutter shoes, for the heads of the
nipples E to be passed through, and the necks of the nipples to be slid sideways
into the narrow part of the slots, which are arranged in alternate order to centralize
the nipples in the rim D, as seen in the dotted portions.
Figure 7 represents a sectional view of a tyre of a road vehicle wheel prepared in'
accordance with my invention, the only difference from the foregoing being the
application of bolts E in place of nipples. To enable this to be more clearly
understood, I take an ordinary un-tyred wooden wheel, and groove the periphery of
the felloes N, I shrink, or otherwise secure plates or a band or rim D¹ thereon, said
band being previously provided with holes, I bore through the holes to the inside of
the felloe N. I place bolts E into the holes of the liner D, and after fitting the
liner temporarily in position on the wheel with the ends of the bolts projecting, I
wrap it over with a strip of rubber A, or it may be a moulded tyre of rubber, the
edges of which are tucked in between the liner D, and the rim D₁ to localize the
tyre, and clamp the rubber between the liner D and the rim D', the nuts F securing
all in close and permanent contact. The liner D may be in two or more segments,
or may be severed only at any point on its circumference.
The nuts F may project on the inside of the felloe, or be recessed, as shown.
The rim D¹ may be omitted and the rubber tyre clamped on to the wooden felloe,
the segments of the felloes being fastened together in any desired manner.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The combination of a rim and inside or outside liner as a means for clamping
wings or edges of flexible tyres between them and onto wheels, as set forth.
2. The tyreing of wheels with a flexible body having wings, or edges capable of
being clamped between rims and liners by nuts and screws, or bolts, which pass from
within, or without the wheel rim, through the outer, or inner liners, or passing
through the inner rim, may be screwed into the outer liner, or rim, for clamping the
wings, or edges of the tyre as described and substantially as represented in the
drawings
.

wheels by a clamping operation between two ring shaped appliances, as herein before
described.
