PROVISIONAL SPECIFICATION.
Improvements in Tyres, Rims, or Wheel Circumferences for Cycle
and other like Wheels.
I, JULIUS GOODMAN of Ravenhurst Road, Harborne, in the County of Worcester,
Commercial Traveller, do hereby declare the nature of this invention to be as
follows:
--
This invention relates primarily to improvements in the rubber tyres, and
encircling rims of the circumferences of cycle and other like wheels, and which
improvements relate in the first part, to the construction or formation of cushion or
like tyres.
In the 2nd part to the affixing or securing of the said tyres to the
metallic rims, which form the inner bearing to the encircling tyre. In the 3rd part
to the rims, which are adapted to present an uncutting and broader bearing surface
to the inside presented part of the tyre. In the 4th part, to the combined tyre and
rim as aforesaid. In the 5th part, to inflated or pneumatic tyres, or combined tyres
and rims constituting a wheel circumference.
In carrying out the improvements of the first part, I make an half-sectioned tyre
of the figure, or somewhat the figure of a parabola or hyperbola, with the middle
inside part of it channelled to an extent about two-thirds of the breadth of the
base, thus leaving as it were, two opposite branches, as the rests, which are concaved
or channelled in their rest faces, and which take upon rolled or beaded parts of the
ritu, as hereinafter described.
Thus the tyre, which has a narrow tread, has its sides slanting outwardly,
alike unto a comb, and with the middle part hollow, formed by the inverted
channel.
The tyre consists of a thin metal inverted half-hoop, or semi-circular sectioned
annulus, with beadings, or rolled metal edges, lying at the entrances to the trough,
and upon these beaded or rolled inside edges, the inside parts of the branches of the
tyre comes, and upon which the same take their bearings, hence an extended bearing,
and cutting of the rubber prevented, whilst leaving a cavity within the inside of
both tyre and rim.
By constructing or forming the tyre and rim as before stated, the cost of the
production of the former is reduced, as compared with ordinary tyres, whilst in
the latter, greater strength combined with lightness, and a broad bearing surface is
attained.
The affixing or securing of the said tyre to the rim, is effected by canvas, or
vulcanised canvas, secured inwardly to the inner bearing or base part of the tyre,
and with the outer ends of the canvas, provided with facing studs or eyelets, by
means of which, the said tyre is laced to the rim.
Thus the tyre, which is attachable, and detachable at pleasure, placed in its
assigned position over the trough of the rim, and there secured by lacing the former
to the latter, which is performed by bringing the canvas extensions around to the
under and inner side of the rim, and then passing and drawing the lacing cord over
and around the studs, and tightened.
Instead of lacing by studs, it may be done by passing the cords through
eyelets.

page_text: In carrying out the improvements in connection with inflated or pneumatic tyres,
I place within the cavity formed between the inside of the tyre, and the inside of the
rim, a combined rubber and canvas tube, which when inflated or blown out, makes
an inside cushion, between the tyre and rim.
In this form of my invention, the tyre may be required to be made only of less
sectioned, or thinner rubber.
Although I have spoken of the rim as being trough shaped, or alike unto the
periphery of a sheave pulley, with side bearings, yet I wish it to be understood that
the said trough is of the longer half of an clipse in cross section, and that the
bearing, edges may be made of any figure as desired.
The canvas layer in connection with the auxiliary tube, placed within the cavity
formed between the presented parts of tyre, and rim respectively, prevents undue
extension of the rubber on inflation.
The inflation tube is provided with a check valve and neck.

Improvements in Tyres, Rims, or Wheel Circumferences for Cycle
and other like Wheels.
I, JULIUS, GOODMAN of Ravenhurst Road, Harborne in the County of Worcester,
Commercial Traveller, 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 improvements in the rubber tyres and metal encircling
rims or felloes, of wheel circumferences, and also to means for securing the tyres.
to the rims.
En carrying out my improvements, I make the tyre of a half section figure or alike
unto the figure of a parabola or hyperbola, with the middle inside part of its base,
channelled or inside grooved.
1. The opposite sides of the base, are concaved or channelled on their rest.
faces, and when in position, take upon inwardly rolled or beaded parts, of
'the rim.
:
Thus, the tyre has its sides slanting outwardly, alike unto a cone or semi-circle,
and with the middle inner part made hollow, and formed alike unto an inverted
.channel.
The.rim consists of a sheet metal and trough shaped annulus, with inwardly or
other rolled metal edges, lying at the entrances to the trough, and upon these rolled
or broadened edges, the opposite inside parts or rests of the tyre, come, so that the
"said tyre is suspended at the.tnouth or entrance of the rim, leaving the middle space
between the said tyre and rim, for cushioning.
By making the tyres of a half section or semi-circular, the quantity of rubber is
minimised, hence cheapness of production.
The affixing or securing of the said tyre to the rim, is effected by canvas,
or vulcanized canvas, webs or skirtings with hook eyelets, or eyelets and lacings.
Thus, the tyre, which is attachable and detachable at pleasure, is placed in its
assigned position over the trough of the rim, and there secured, by lacing the
former to the latter, which is performed by bringing the canvas extensions
around to the under and inuer side of the rim, and then passing and drawing the
lacing cord over and around the hook studs, or through-the eyeletings.
The tyre may be secured to rim by cement, or otherwise, instead of by
lacing *.

mecame rim or felloe, constructed or made according to one-form of my
The tyre is shown affixed to the rim by lacing.
Figure 2 represents upon an enlarged scale, an elevation, partly in section,, of a
portion of the circumference of the said wheel, and comprehending both tyre,, rim,
and affixing means.
Figure 3 represents a cross section of the said tyre and rim, upon the dotted
.line B Figure 2, showing the structural formation or character of the tyre, like-
wise the shape of the cross section of the rin, and also the means employed' in
connecting the former to the latter.
Figure 4 represents the tyre and its connections separately, and Figure 5 the rim
separately, with the spoke ends shown with it.
The same letters of reference indicate corresponding parts in Figures 1 to 5.
a is the tyre, of somewhat the figure of a semi circle in cross section,, or that of
a parabola or hyperbola, according to the breadth of the tread of the same, as may
be required, and which tyre has its middle inside part a², channelled or grooved, and
with the outside parts a³, likewise grooved or shaped to fit or seat themselves upon
the rolled rests 62, of the open topped trough shaped rim b, to the inside middle: part
of which, spokes c are connected.
The base or inside part of the semi-section tyre, is lined with canvas d,
haying side or web extensions d², carrying hooked eyelets e; by means of which the
said webs, are, by lacings, or by lacing cords f, secured around the outside of the
said rim, hence the securing of the tyre also to it.
By employing a canvas inside support, the rubber is confined within desired limits,
in respect to the inward bulging or displacement of the same through the open top
of the rim.
By placing or seating the sides of the said canvas covered inside arch section tyre
upon the opposite rolled edges of the rim, which is also alike unto an inverted arch,
the bases of the two arch sections come together, forming a complete figure, with
an annular air cavity or space, disposed between them, and which annular
space, which runs within the wheel circumference, constitutes a cushioning field for
the tyre.
The lacings are passed over the hook eyelets, upon the two opposite sides of
the webbing, and pass crosswise in a lacing manner, under the rim.
Figure 6 represents in elevation, a portion of a wheel circumference, with a
tyre secured to a rim by eyelet lacing, instead of by hook lacing, as in the previous
figures.
Figure 7 is a cross section upon the dotted line C D Figure 6.
Figure 8 is an underside plan of the tyre, showing the side rests a³, and the
middle channel a', also the hook eyelets e.
Figure 9 represents a top side plan of the rim, showing the rolled sides 62, and
the middle cavity ', of the rim b.
Figure 10 shows my invention in connection with a pneumatic tyre.
a is a pneumatic tyre, having upon its under or inner side, an attached
canvas d, with side extensions or webs d', which pass over the inside rolled
edges of the rim b, and is, around the underside of the said rim, secured by
lacings f
By disposing the tyre with respect to the rim, the former is cushioned within
the cavity of the latter, hence a cushioned pneumatic tyre.
I am aware of John Samuel Smith's Patent No. 14203 of 1890 and make no claim
to anything therein described or claimed.
Having now particularly described and ascertained the nature of my said inven-
ion, and in what manner the same is to be performed, I declare that what I
claim is :-
:-
First In a suspension and cushion tyre, making the same of an arch section,
or of an inside channelled semi-circular figure, with canvas or vulcanized canvas

upon its inside, or inwardly presented part or parts, substantially as described and
set forth in Figures 1 to 9.
Secondly: Securing half-section cushion tyres to their rims, by side webs or
extensions, substantially as described and set forth in Figures 1 to 9.
Thirdly-The combination with a half-section tyre, or webs or side skirtings,
with hook eyelets, studs or eyelets, with lacings for the attachment of the tyre to
the rim, substantially as described and set forth in Figures 1 to 9.
Fourthly:- A rim, making the same of a trough figure, and with the edges thereof
rolled inwardly, and upon which rolled or inwardly directed edges, the opposite
sides of the inner part of a tyre come and take their bearing, leaving the cavity
or space lying below the said edges for cushioning, substantially as set forth in
Figures 1 to 9.
Fifthly-A wheel circumference, consisting of two arch-section-shaped members
or parts, viz.: a rubber tyre and a metal rim, with the opposite sides of the one,
presented to the opposite sides or terminal parts of the other, hence an enclosed
figure, with an air space or cushioning cavity between the middles of the presented
parts of them, substantially as set forth in Figures 1 to 9.
Sixthly: A cushion inflated tyre or wheel circumference, as set forth in
Figure 10.
Dated this 3rd day of November 1891.
