Improvements in Pneumatic Tyres and Rims for Wheels of
Velocipedes and other Road Vehicles.
We, HEBER EDWIN HOWARD, of Sulby Lodge, Grove Lane, Yardley, in the
County of Worcester, Engineer's Assistant, and VIOLETTA HOWARD (Mrs.), of
Sulby Lodge, aforesaid, do hereby declare the nature of this invention to be as
follows:
This invention relates to the improvements hereinafter described in pneumatic
tyres and rims for wheels of velocipedes and other road vehicles and has for its
object to provide a simple and effective arrangement for holding a pneumatic tyre
firmly on the rim of the wheel without the aid of wires or other clipping devices.
Our invention consists essentially in the formation of a rim containing a number
of grooves or undulations extending along or circumvesting the inner surface of
the rim..
We provide the tyre along the part or parts fitting the rim with a number of ribs
or corrugations to exactly fit the grooves or undulations in the rim.
We may in some cases form a cross cut or depression in the rim and on the tyre
a raised part or projection so as one may engage within the other to prevent the
tyre from creeping on the periphery of the rim.
:
In placing our improved tyre upon the rim we may or may not cement or other-
wise fasten one side of the tyre into the periphery of the rim the other portion
having ribs or projections to fit the grooves of the rim is held firmly therein by
inflation of the tyre, and by deflation the one half is readily and expeditiously
removed from its seat in the rim for repairing punctures and other purposes.
Dated this 2nd day of March 1897.

Improvements in Pneumatic Tyres and Rims for Wheels of
Velocipedes and other Road Vehicles.
We, HEBER EDWIN HOWARD, of Sulby Lodge, Grove Lane, Yardley, in the
County of Worcester, Engineer's Assistant, and VIOLETTA HOWARD (Mrs.), of
Sulby Lodge, aforesaid, 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:-
This invention relates to the improvements hereinafter described in pneumatic

page_text: tyres and rims for wheels of velocipedes and other road vehicles and has for its
object to provide a simple and effective arrangement for holding the tyre firmly on
the rim of the wheel without the aid of wires and other clipping devices.
Our invention consists essentially in the formation of a rim containing a number
of grooves or undulations extending along or circumvesting the inner surface.
We provide the tyre towards the margin edges which lie in the rim with a
number of ribs or corrugations running parallel with and fitting the grooves or
undulations in the rim.
In placing our improved tyre upon the rim we may if desired cement or otherwise
fasten one side of the tyre into the periphery of the rim the other portion con-
taining ribs or projections to fit the grooves or undulations aforesaid is held firmly
in the rim by inflation and by deflation is readily and expeditiously removed from
its seat therein for the purpose of repairing punctures and the like.
In order that our invention may be more clearly understood we will describe it
by reference to the accompanying drawings the same letters of reference indicating
similar parts in the several views:
Figures 1 and 2 represent in cross section a tyre fitted in the rim of the wheel.
Figure 4 shows in plan and cross section a portion of the tyre stretched out flat.
Figures 3, 5 and 6 are modifications of our invention.
A is the tyre having ribs A¹ formed thereon B is the rim having a corresponding
number of grooves B₁ into which the aforesaid ribs A¹ fit. We may if desired
cement one side 1 of the tyre A to the rim thus allowing the other side to be
taken out after deflating the tyre.
In Figure 1 we show an inner air tube and outer cover. Figure 2 shows the
tyre and rim used without the inner air tube and in Figure 3 a rim of different
section is shown.
In Figure 5 the tyre A is held in the rim by four ribs A2 two on either side and
Figure 6 shows a tyre and rim having ten ribs A³ and grooves B³ five on either
side.
In Figure 7 we show a tyre having one rib D2 on one side and on the other side
we form three ribs of a different section to those shown at Figures 1, 2, 3, 4, 5,
and 6. Or the side to be cemented in the rim need not have any ribs at all.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is: :-
1. The method of attaching a pneumatic tyre to the rim of the wheel by pro-
viding the tyre cover with two or more ribs on each side which are held in corres-
ponding grooves in the rim by the pressure of the air within the tyre substantially
as described and illustrated in the accompanying drawings.
2. The method of attaching a pneumatic tyre to the rim of a wheel by cementing
or otherwise fixing one side of the tyre cover to the rim and providing the other
side of the cover with two or more ribs which are held in corresponding grooves
in the rim by the pressure of air within the tyre substantially as described and
illustrated in the accompanying drawings.
3. The improvements in pneumatic tyres and rims for wheels of velocipedes and
other vehicles substantially as described and illustrated in the accompanying
drawings.
