A New or Improved Combined Wheel Rim and Tyre.
We, SAM THOMAS RICHARDSON, of 3A, Rea Street, Birmingham, Cycle Manu-
facturer, and RICHARD PRICE, of 3A, Rea Street, Birmingham aforesaid, Cycle
Manufacturer, do hereby declare the nature of this invention to be as follows:-
-
This invention consists of the herein described new or improved combined
wheel rim and tyre for road vehicles motor carriages bicycles and other velocipedes.
In carrying out this invention we provide a trough section wheel rim which is
made of a strip of steel or other suitable metal of the proper width drawn on a
draw bench to a cross section which somewhat resembles a horse-shoe, that is to
say, the cross section of the wheel rim is of a very deep trough' section with the
bottom of the trough somewhat of a semi-circular form with the sides continued up
to the periphery of the rim and gradually nearing each other forming an opening
all round the periphery which is considerably narrower than the widest part of
the rim. This wheel rim is made of one thickness of metal. The said tyre consists
of an air inflated indiarubber or like tube which is entirely enclosed in the said
wheel rim but leaving a space between the upper part of the said air tube and the
sides of the rim. Bearing upon the said air tube we provide an indiarubber or
other suitable tread part of the tyre which projects from the narrow opening
round the periphery of the rim the said outer part or tread of the tyre having
an enlarged base which bears upon the said air tube and is divided into two
flanges which, when the air tube is inflated, are fitted between the upper part of
the air tube and the sides of the rim, so that it is quite impossible for the tread
part to work out of the rim when the tyre is in use as the base of the tread part
is considerably wider than the said narrow opening round the rim through which
the tread part protrudes.
With the said tread part and rim above described we may use, instead of the
said air tube, a filling of cork or other suitable material in the rim for the tread
part to bear upon, the said cork or other suitable material being either enclosed
in a separate tube inside the hollow rim or arranged in the hollow rim without
the enclosing tube.

facturer, and RICHARD PRICE, of 3A, Rea Street, Birmingham aforesaid, Cycle
Manufacturer, 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 consists of the herein described new or improved combined
wheel rim and tyre for road vehicles motor carriages bicycles and other velocipedes.
We will describe this invention by referring to the accompanying drawing on
which Fig. 1 is a cross section of one construction of a combined wheel rim and
tyre constructed according to this invention; Fig. 2 is a cross section of another
construction of the same; Fig. 3 shews separately a portion of the filling material
of the wheel rim shewn in Fig. 2; Fig. 4 is a cross section of another construction
of our invention; Fig. 5 is a plan shewing a portion of the filling material of the
combined wheel rim and tyre shewn by Fig. 4; Fig. 6 is a cross section of another
construction of our invention.
The same letters of reference indicate the same or corresponding parts in all
the figures of the drawing.
'
In carrying out this invention we provide a trough section wheel rim A which
is made of a strip of steel or other suitable metal of the proper width drawn on a
draw bench to the cross section represented in Figs. 1, 2, 4 and 6 and bent into
the required circular wheel rim and the ends brazed together but to this wheel
rim itself we make no claim. It will be understood that the cross section of the
wheel rim is of a very deep trough shape with the bottom a¹ of the trough of
somewhat of a semi-circular form and the sides a² a³ continued to the periphery 2
of the rim and gradually nearing each other forming an opening all round the
periphery which is considerably narrower than the widest part of the rim.
This wheel rim is made of one thickness of metal. The tyre consists of a filling
of cork or other suitable material in the rim A and the indiarubber or like tread
part B bearing upon the said filling material which (as hereinafter described) is
either enclosed in a separate india rubber tube inside the hollow rim A or arranged
in the hollow rim A without the enclosing tube. The indiarubber or other like
tread part B of the tyre projects from the narrow opening a round the periphery
of the rim and has an enlarged base 61 which is forced into the rim through the
narrow opening at the periphery a and bears upon the filling material in the
rim. A. This filling material may be constructed and arranged in various ways
as we will now describe.
In the arrangement shewn by Fig. 1 the filling material is hemp or other rope C
coiled round and round the trough section wheel rim until there is only space
enough to receive the enlarged base 61 of the indiarubber tread part B which thus
bears upon the rope filling material C.
In the arrangement shewn by Fig. 2 the filling material consists of two cork
rings D D each formed of short pieces of cork of the section shewn by Fig. 5
fixed together at their ends and enclosed in the indiarubber tube d' which surrounds
the same. These rings can readily be sprung into position one at a time through
the narrow opening in the periphery at of the wheel rim so that the base b¹ and
indiarubber fread part B will bear upon them.
In the arrangement shown by Figs. 4 and 5 the interior of the rim A is filled
with pieces of cork forming two rings D¹ Da without the enclosing indiarubber

page_text: tube these pieces of cork being of such a size and shape as shewn for instance
by Figs. and 5 that they can be passed in through the narrow opening of the
periphery at and glued or otherwise cemented together inside the rim for the
base 61 of the tread part B to bear upon.
!
Fig. 6 shews another arrangement in which the filling material in the hollow
rim B is formed of pieces of cork D1 D2 D3 built up and glued or otherwise fixed
together so as to partly fill up the interior of the hollow rim A for the base 6¹
of the tread B to bear upon.
Having now particularly described and ascertained the nature of our said in-
vention, and in what manner the same is to be performed, we declare that what we
claim is:-
The improved combined wheel rim and tyre consisting of the combination of the
wheel rim A made of the shape shewn having a narrow opening round the
periphery, the indiarubber tread part B projecting through said narrow opening
and made with an enlarged base b₁ within the rim and a filling of suitable material
contained within the hollow rim A on which the tread part B rests, substantially
as set forth.
