PROVISIONAL SPECIFICATION.
Improvements in and connected with Rims and Tyres of Wheels for
Cycles and other Vehicles.
I, JAMES GEORGE GALLEY, of No. 181 Neville Road, Upton Park, in the County
of Essex Engineer do hereby declare the nature of this invention to be as follows:-
My invention relates to certain improvements in and connected with rims and
tyres of wheels for cycles and other vehicles as described in the Specification of
Letters Patent granted to me No. 15344 of A.D. 1891 and has for its object the
provision of ready means for securing the tyres to the rims, and also detaching for.
repairing or other purposes; attaining at the same time a high degree of elasticity
when said tyres are inflated.
In order that my invention may be the better understood, I have appended the
accompanying sheet of drawings in which
Figure 1 is a section of a tyre and rim, and Figure 2 a similar section, showing
a modification thereof, Figures 3 and 4 are sectional views showing other modifications
and
Figures 5 and 5 are respectively a sectional elevation, and sectional plan upon the
line A. B. of a compound valve for inflation and deflation.
Figures 6 and 7 are sectional views showing the tyre or cover detached from
the rim.
Similar letters of reference are used to indicate corresponding parts throughout
the several views.
In carrying my invention into effect I construct an annulus A, which when fitted
upon the metal rim E, Figure 1, and inflated, forms a single tubular airtight tyre..
Upon and around the edges of said annulus A are formed small tubes D D' which are
capable of separate inflation after being placed in position within the open tubes or
channels B B formed around the rim E. A strip of soft elastic material F is fixed'
around the metal rim E to make it airtight where it is pierced for the insertion of
the spokes, and the edges are free so that the wedge shaped edges G G¹ of the
annulus A may be tucked between said edges and the rim E. The internal pressure
within A when inflated presses F tightly upon it so as to secure an air tight joint..
In order to inflate the tyre A, and the side tubes D D' by one pumping operation I
use the compound valve arrangement shown attached by Figure 1, but in detail, and
drawn to a larger scale by Figures 5 and 5*. The central tube a with its back
pressure valve and pump nozzle is attached to the strip F so as to inflate the tyre A
when it is in position. Similar tubes 6 6¹ communicate with the side tubes D Dĭ and
are provided with separate valves, and instead of being provided with pump nozzles,
may have airtight terminal caps screwed or otherwise attached thereto. The three
tubes abbare shouldered so as to pass through a hollow cross piece e which connects
the tubes below the valves. Thus, when the tyre A is in position, the pump or other
inflator may be attached to the nozzle of a, and by one action may inflate A, D and D,
thus firmly attaching the tyre to the rim, and affording a large bearing surface to.
effectually prevent "creeping." If it is necessary at any time to obtain access to
the interior surface of the tyre A for the purpose of repairing a puncture or the like
it is not necessary to remove it bodily from the rim E. One of the side tubes,
say D, may be deflated by removing the cap upon the tube 6 and opening the valve,
and the tyre A being also deflated through a, the lock nut d is removed, which

page_text: secures 6 to the cross piece c, and the tube D may then be lifted out of the channel B
and the tyre A opened, the other side being held by the still inflated tube D¹. The
operations of detaching and replacing are thus readily and quickly performed. The
tyre A is shown detached by the sectional view Figure 7, and may be made of
rubber, composition, insertion or any suitable material, and the side tubes D D₁
may be formed as an integral part thereof, or may be made separately and attached
thereto by means of solution or in any suitable manner. A modification of the
arrangement hereinbefore described is shown by Figure 2, in which the side
tubes D D¹ are not separately inflated or deflated relatively to the tyre A, but
communicate with the interior thereof by means of openings e e'. The rim in this
case is shown single, but it may be double as in Figure 1. Another modification
of Figure 1 is shown by Figure 3 in which the annular tyre A is a cover only,
enclosing an interior tube H which is separate from it, and is inflated through the
tube a in the manner hereinbefore described. Figure 4 shows another modification,
of Figures 1 and 2, in which the annulus A is inflated or deflated simultaneously
with the side tubes D D' through the tubes b 6' either being used for those purposes.
Figure 6 is a sectional view of the tyre A shown by Figure 3, shown detached, and
illustrating the modification of the shape of the edges G G', which in each case
form an essential feature of my said invention.

Improvements in and connected with Rims and Tyres of Wheels for
Cycles and other Vehicles.
I, JAMES GEORGE GALLEY of No. 181 Neville Road, Upton Park, in the County
of Essex, Engineer 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 :-
My invention relates to certain improvements in and connected with rims and
tyres of wheels for cycles and other vehicles as described in the Specification of
Letters Patent granted to me No. 15344 of A.D. 1891, and has for its object the.
provision of ready means for securing the tyres to the rims and also detaching
for repairing or other purposes; attaining at the same time a high degree of
elasticity when said tyres are inflated.
In order that my invention may be the better understood, I have appended the
accompanying sheet of drawings, to my Provisional Specification, to which reference
is made in the description herein set forth.
Figure 1 is a section of a tyre and rim, and Figure 2 a similar section showing a
modification thereof. Figures 3 and 4 are sectional views showing other modifications,
and
Figures 5 and 54 are respectively a sectional elevation and a sectional plan upon the
line A. B. of a compound valve for inflation and deflation.
Figures 6 and 7 are sectional views showing the tyre or cover detached from the
rim.
With the Complete Specification I append a sheet of drawings in addition to the
foregoing in which
Figures 8 and 9 are sectional views of a rim and tyre in which certain modifi-
cations are introduced based upon the same principle.

page_text: Figure 10 is a section of an elastic liner, sprung upon the periphery of the rim.
Similar letters of reference indicate corresponding parts throughout the several!
views.
In carrying my invention into effect I construct an annulus A, which when fitted!
upon the metal rim E Figure 1, and inflated, forms a single tubular air-tight tyre..
Upon and around the edges of said annulus A. are formed small tubes D D' which are
capable of separate inflation after being placed in position within the open tubes or
channels B B formed around the rim E. A strip of soft elastic material F is fixed
around the metal rim E to make it air-tight where it is pierced for the insertion of the
spokes, and the edges are free, so that the wedged shaped edges G G₁ of the
annulas A may be tucked between said edges and the rim B. The internal pressure
within A when inflated presses F tightly upon it so as to secure an air-tight joint.
As a modification I may cause the edges G G₁ to impinge upon the strip F
as shown by Figures 8 and 9, said strip being sprung upon the rim and held by reason.
of its elasticity. In order to inflate the tyre A, and the side tubes D D₁ by one.
pumping operation I use the compound valve arrangement shown, attached by-
Figure 1, but in detail, and drawn to a larger scale by Figures 5 and 5. The
central tube a with its back pressure valve and pump nozzle is attached to the strip F
so as to inflate the tyre A when it is in position. Similar tubes bb' communicate with.
the side tubes D D¹ and are provided with separate valves, and instead of being.
provided with pump nozzles, may have air-tight terminal caps screwed or otherwise.
attached thereto. The three tubes a b bare shouldered so as to pass through a hollow
cross piece c which connects the tubes below the valves. Thus, when the tyre A is in
position, the pump or other inflator may be attached to the nozzle of a, and by one
action may inflate A, D and D', thus firmly attaching the tyre to the rim and affording
a large bearing surface to effectually prevent "creeping." If it is necessary at any
time to obtain access to the interior surface of the tyre A for the purpose of repairing
a puncture or the like it is not necessary to remove it bodily from the rim E. One
of the side tubes, say D, may be deflated by removing the cap upon the tube b and
opening the valve, and the tyre A being also deflated through a, the lock nut dis
removed, which secures to the cross piece c, and the tube D may then be lifted out
of the channel B and the tyre A opened, the other side being held by the still inflated
tube D'. The operations of detaching and replacing are thus readily and quickly
performed. The tyre A is shown detached by the sectional view Figure 7 and may
be made of rubber, composition, insertion or any suitable material, and the side
tubes D D may be formed as an integral part thereof, or may be made separately and
attached thereto by means of solution or in any suitable manner. A modification of
the arrangement hereinbefore described as shown by Figure 2 in which the side
tubes DD are not separately inflated or deflated relatively to the tyre A, but
communicate with the interior thereof by means of openings e e¹. The rim in this
case is shown single, but it may be double as in Figure 1. Another modification of
Figure 1 is shown by Figure 3 in which the annular tyre A is a cover only, enclosing
an interior tube H which is separate from it, and is inflated through the tube a in the
manner hereinbefore described. Figure shows another modification of Figures 1
and 2, in which the annulus A is inflated or deflated simultaneously with the side.
tubes D D through the tubes 66 either being used for those purposes. Figure 6.
is a sectional view of the tyre A shown by Figure 3, shown detached, and illustrating
the modification of the shape of the edges G G₁, which in each case form an essential
feature of my said invention. The shape of the rims shown by Figures 2, 3, and 4,.
in which a return edge is provided upon each side, allows a larger surface in contact,
and relieves the weaker parts of the tyre from undue strains.
Referring now to Figures 8 and 9 it will be seen that the strip of indiarubber or
other elastic material F, (shown detached by the sectional view Figure 10) is sprung
upon the rim E and retained in position by its elasticity, without using any cement or
other means for attachment. The projecting ends of the rim rr, similar to the
shapes shown by Figures 2, 3 and 4 serve to retain the tyre A in position, and the
pressure due to inflation preserves the hermeticity by mere pressure upon F. Any of

page_text: the rims shown as examples by the 'drawings may be doubled or returned in the
process of manufacture in the manner illustrated by Figure 1, thus affording increased
structural strength for heavy traction when the invention is applied to vehicles other
than cycles or velocipedes.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is ;-
First. In a tyre for the wheels of cycles and other vehicles the construction and
use of an elastic annulus with side tubes capable of separate inflation and deflation,
and projecting wedge shaped edges substantially as herein described and shown by
Figures 1, 3, 6 and 7 of the appended drawings.
Second. A rim for cycle and other vehicle wheels formed with tubes or channels
around each edge, and an elastic strip with free edges fixed around the outside thereof,
substantially as herein described and shown by the drawings.
Third. In a tyre for the wheels of cycles and other vehicles, the use of an elastic
acnulus with side tubes arranged for simultaneous inflation and deflation substantially
as herein described and shown by Figures 2 and 4 of the appended drawings.
Fourth. In a tyre for the wheels of cycles and other vehicles the use of a hollow
cross-piece connecting three tubes, each provided with a back pressure valve, and one
with a pump nozzle substantially as and for the purpose herein described and shown
by Figures 1, 3, 5, and 5 of the drawings.
Firth. In a tyre for the wheels of cycles and other vehicles consisting of an
annulus with side tubes, the method of and means for inflating or deflating the whole
through a tube connected to one of the said side tubes substantially as herein described
with reference to Figure 4 of the appended drawings.
Sixth. In tyres for the wheels of cycles and other vehicles, the combination of an
annular cover with side tubes and wedge shaped edges enclosing an air tube or
vessel substantially as herein described and shown by Figure 3 of the appended
drawings.
Seventh. In tyres and rims for the wheels of cycles and other vehicles, the means
for, and method of, fixing an annulus A to a rim E by inflated side tubes D D' fitting
within channels B'B' and securing an air tight joint by compressing edges G GI
between an elastic strip F and the surface of the rim E substantially as herein
described and shown by the appended drawings.
Eighth. In tyres and rims for the wheels of cycles and other vehicles, the means
for and method of fixing an annulus A to a rim E by inflated side tubes D D¹ fitting
within channels B B' and securing an air tight joint by compressing the edges G G₁
upon an elastic strip F previously sprung upon the periphery of the wheel,
substantially as herein described and shown by Figures 8 9 and 10 of the appended
drawings.
'
Ninth. In rims for the wheels of cycles and other vehicles the use of a return
edge on both sides above the open tubes or channels, substantially as herein described
and shown by Figures 2, 3, 4, 8, 9 and 10 of the appended drawings.
