Improvements in or connected with Rims or Felloes and Inflated
Tyres for the Wheels of Velocipedes and other Vehicles.
I, JOSHUA FIRTH. BARLOW, of The Morelands, Middleborough Road, Coventry, in
the County of Warwick, Outfitter's Assistant, do hereby declare the nature of this
invention to be as follows:-
This invention refers to rims or felloes and inflatable tyres therefor, wherein the
rim is formed with channelled circumferential edges each channel having a circum-
ferential slot, and each channel being also divided at one or more places; the tyre
has beaded or enlarged edges, also divided at a part or parts, and the edges are
inserted into the rim channels by rotating the tyre circumferentially relatively to.
the rim.
In tyres of this character as hitherto constructed, or proposed to be constructed,
disadvantages and difficulties in manipulation have been experienced, in that to
insert the divided edges of the cover into the channels has been troublesome, the
tyre after application to the rim has had a tendency to creep, that is to move upon
the rim, through its contact with the road; it has been generally necessary to
provide means for covering the divided or open parts of the channels, and the
formation of the channels has been such that the tyre. edges when fitted and drawn
sufficiently tight to prevent creeping, has rendered it difficult, without special
appliances to remove the said tyre from the rim by reason of its frictional resistance-
to the circumferential motion.
Now the object of my invention is to produce a rim and tyre of the class as
herein before first stated, and at the same time to entirely obviate the disadvantages
and difficulties common to the same.
According to my invention I forin the rim with two channelled edges of somewhat
rectangular form in cross section, or of other form if desired, but with the outer
peripheral surface flat, or slightly bent inwards or concave. In this flat outer surface
of the channel I form a circuinferentially extending slot, or such a slot is formed by
the aforesaid construction. At one or several places around the rim, say for the
purpose of this description at one place, I cause the outer surface of one channel to be
depressed, and in and near the end of this depressed part the circumferential slot is
ended or closed, while at a very short distance from the said depressed part of the
channel, the outer surface of same is divided and stands above the. depressed part,
again presenting an open slot.
The other channel is similarly formed.
The pneumatic tyre proper or where a double tube tyre is employed, as in the
example now described, the outer cover is formed with enlarged edges, which in cross
section are somewhat square in form or project at, about approximately right angles
from each side of the cover say of inverted 1 section, although beads of any desired
section may of course be used if desired. Such edges may be formed in any convenient
manner, generally by folding the canvas and sewing same, and the said edges may be
stiffened and rendered waterproof, but not inextensible, as they should accommodate
themselves to exactly fit the circumference of the rim..

page_text: The aforesaid edges are divided and are so formed that at a division one part of the
edge extends below the adjacent part so that in adjusting the cover to the rim the
lower projecting divided edge is inserted into the upstanding open slot of the channel,
and the cover is then moved circumferentially round the rim, until this lower projecting
part of the edge is brought to the end of the slot in the channel, when the adjacent
edge at the division will be located in the open and upstanding part of the channel,
the whole edge of the cover being then within the said channel.. The termination of
this upper edge of the cover may have an enlargement, to act as a stop.
By this construction of the tyre or cover at its edges and divided parts, in
combination with the construction of the rim as aforesaid I am enabled to at once
enter the cover edges within the channels, without encountering any difficulty in so
doing, while the tyre is then simply revolved, until it reaches the stop, when its
proper position is mechanically assured, and the formation of the channels and cover.
edges, render impossible for the tyre when deflated to have become fixed in the
channels by the previous tension caused by the inflation, or other causes.
Generally I arrange that the india rubber tread of the outer cover, shall not
extend into the channels, and the slots in the latter need not necessarily be made
in the centre of the outer surface of the channels, but may be made upon one
side of the same.
Although I prefer the arrangement here described I do not limit myself to the
employment of two channels as it is obvious that by a slight modification to the
edges of tyre the same principles of construction are applicable to a rim having one
channel only, or the two channels may be situated at some distance from the edge of
rim or may be close together at the bottom of rim.

Improvements in or connected with Rims or Felloes and Inflated
Tyres for the Wheels of Velocipedes and other Vehicles.
I, JOSHUA FIRTH BARLOW, of The Morelands, Middleborough Road, Coventry, in
the County of Warwick, Outfitter's Assistant, 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 refers to that class of inflated elastic tyres, and rins or felloes for
same, wherein the rim is formed with a circumferential channel at each edge,
each channel having a circumferential slot and being divided transversely at
one or more places; the tyre or outer cover has beaded edges, also transversely
divided, and such edges are inserted into the rim channels, and the tyre or
outer cover fixed in position by rotating it circumferentially relatively to the rim.
In tyres and rims of this character as hitherto constructed, or proposed to be
constructed, disadvantages accruing from the construction and difficulties of
manipulation also incident thereto, have been experienced, in that, to insert the
divided edges of the cover into the channels has been troublesome, and the tyre
or cover after application to the rim, having a tendency to "creep" that is to move
upon the rim through its contact with the road. It has been generally necessary to
provide means for covering the divided or open parts of the channels, and the formation
of the channels has been such that the tyre or cover edges, when fitted and drawn
sufficiently tight to prevent creeping, has rendered it difficult, without special
appliances, to remove the said tyre or cover from the rim by reason of its frictional
esistance to the circumferential motion.

page_text: Now the object of my invention is to produce an improved rim and tyre of the
class as hereinbefore first stated, and at the same time to entirely obviate the
disadvantages and difficulties common to the same.
The accompanying drawings shew the construction of my improved rim and tyre,
Fig. 1, being a cross section of the rim and tyre in position; Fig. 2, is a side elevation
of the same, a part of the tyre and rim being cut away to shew the formation of a
channel, at that part where the edge of the tyre is to be inserted. Fig. 3, is a plan of
the rim, the tyre having been removed; and Fig. 4, a cross section on the line X Y
of Fig. 3. Fig. 5, is a perspective view of a part of the rim. Fig. 6, is a side elevation
of a portion of the tyre or outer cover shewing a divison in the edge thereof. Fig. 7,
shews a portion of an outer cover edge, showing an enlargement of the said edge, and
Fig. 8, is a cross section shewing a slightly modified construction of rim and tyre
suitable for example for roadster pattern tyres.
According to my invention the channels A at the edges of the rims or felloes A¹,
are of somewhat rectangular form in cross section as shewn, or of other form if desired,
but with the outer peripheral surface A2 flat or approximately flat. In this flat outer
surface A2 of each channel, I form a circumferentially extending slot B, or such a slot
is formed by the construction shewn at Fig. 1, or Fig. 8.
At one, or several places around the rim, say for the purpose of this description and
as shewn, at one place, Figs. 2, 3, 4 and 5, I cause the outer surface A2 of one channel
to be depressed as at A³, and in and near the end of this depressed part A³, the
circumferential slot B Figs. 3 and 5, is ended or closed at B¹, while at a very short
distance from the said depressed part A³ of the channel, the outer surface of same
is divided, and stands as at Fig. 2, above the depressed part A³ presenting the open
ended slot B.
The other channel is similarly formed.
The pneumatic tyre proper, or where a double tube tyre is employed, as in the
example now described, the outer cover C is formed with enlarged edges C', which in
cross section project at about approximately right angles from each side of the cover
(or from one side of the cover as at Fig. 8), although beads of any desired section
may of course be used if desired. Such edges C¹ may be formed in any convenient
manner, generally by folding the canvas and sewing same, and the said edges may
be somewhat stiffened and rendered waterproof but are still flexible, and sufficiently
extensible to accommodate themselves to exactly fit the circumference of the rim.
D Fig. 1 is the usual inner air containing tube.
The aforesaid edges C₁ of the outer cover are divided as at C2 Fig. 6, and are so
formed that at the division, one part C³ of the edge extends below the adjacent
part C4, so that in adjusting the cover C to the rim A¹ the lower projecting divided
edge C³ is inserted into the upstanding open slot of the channel, and the cover C is
then moved circumferentially around the rim, until this lower projecting part C³ of
the edge is brought to the end B₁ of the slot in the channel, when the adjacent
edge C at the division will be located in the open and upstanding part of the
channel, the whole circumference of the edge of the cover C being then within the
aid channel. In some cases I may, as is shewn at Fig. 7, form an enlargement C
on each edge of the cover, to act as an auxiliary stop to the circumferential
notion given to the cover when applying same to the rim.
By this construction of the tyre or cover C at its edges and divided parts, in
ombination with the construction of the rim A' as aforesaid, I am enabled to at once
nter the cover edges at C³ within the channels A, without encountering any difficulty
n so doing, while the cover C is then simply revolved until it reaches the stop at B¹,
hen its proper position is mechanically assured, and the formation of the channels
s at A2 and cover edges C¹, render it impossible for the tyre when deflated to have
ecome fixed in the channels by the previous tension caused by the inflation, or other
auses.
Generally I arrange that the india rubber tread of the outer cover C shall not
xtend into the channels, and the slot B in the latter need not necessarily be made in
he centre of the outer surface A² of the channels A, but may be made as at Fig. 8,

page_text: upon one side of same, this arrangement being specially suitable for roadster tyres,
it being impossible for wet or dust to enter the grooves.
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 with an inflatable tyre having enlarged or beaded laterally
projecting edges, extending circumferentially at each side of same, transverse divisions
in such edges, the termination of the enlarged edges of the tyre being on different
levels; or a rim having circumferential channels to receive and hold the enlarged
edges of the tyre, circumferential slots in the peripheral surfaces of the channels
through which the sides of the tyre extend, divisions in the said peripheral surface of
the channels, the said surfaces on one side of the division being inclined to the bases
of the channels where the slots are terminated and form stops for the edges of the
tyre when in place, the slots of the peripheral surfaces of the channels at the other
sides of the divisions being: open ended to permit entry therein of the lower level
terminations of the tyre edges, the said tyre being circumferentially revolved until
brought to rest by the stops with its enlarged edges in the channels, substantially as
set forth.
2. The combination with an elastic air containing tube and an outer cover having
laterally projecting enlargements on its circumferential edges, transverse divisions in
such edges, the terminations of the enlarged edges of the cover at the divisions being
at different levels; of a rim having circumferential channels, to receive and hold the
enlarged edges of the cover, circumferential slots in the peripheral surfaces of the
channels, through which the sides of the cover extend, divisions in the said peripheral
surfaces of the channels, the said surfaces on one side of the divisions being inclined
to the cases of the channels where the slots are terminated, and form stops for the
edges of the cover when in place, the slots in the peripheral surfaces of the channels
at the other sides of the division being open ended to permit entry therein of the lower
level terminations of the cover edges, the said cover being circumferentially
revolved until brought to rest by the stops, with its edges in the channels as set
forth.
3. The general construction and combination of parts composing my improvements
in or connected with rims or felloes and inflated tyres for the wheels of velocipedes
and other vehicles, all substantially as and for the purposes described and illustrated
with reference to the accompanying drawings.
