PROVISIONAL SPECIFICATION.
Improvements in and relating to Cycle and other Wheels.
I, HENRY JAMES CREESE of No. 50 Chester Street Leicester in the County
of Leicester Cycle Manufacturer, do hereby declare the nature of this invention to
be as follows:-
This invention refers to improvements in and relating to cycle, and other wheels
having pneumatic tyres thereon, consisting of a block end air tube of the ordinary
kind surrounded by a canvas bag and protected by a sheet rubber cover in the
usual way. The object of my invention is to facilitate the removal of the tyre and
the air tube when punctured, and a simple means of securing the tyre without
sticking it to the wheel rim, so that it can be if required wholly removed from the
rim in a few minutes. In racing cycles a race has often to be thrown up through
collapse of the air tube and of the considerable time it takes to put a duplicate tyre
in, or mend the puncture. I desire to obviate this by providing means whereby a
duplicate tyre can be put on and blown up to replace another in a much shorter
time than is now the case, besides being able to make the cycle or other wheels
lighter.
To enable anyone to get at the air tube quickly, I arrange upon the canvas bag
near the valve a man hole, or opening closed by lacing or the like, such man hole
being made of lace strips, either eyeletted or not, put at the required intervals
parallel to each other and extending lengthwise several inches so that upon the air
tube becoming punctured and collapsing I can by releasing the "lace strips" and
tying something round the tube, and take out the valve from the cover, take out
the tube patch or otherwise mend it, put it in again, tighten up, inflate it, then
secure the tyre in the wheel rim again by the following arrangement. The outer
cover is secured to the canvas bag in the ordinary way, but before putting them
together, I secure on the inside of the outer cover, or length of sheet rubber
transverse strips, or straps of canvas, tape, webbing or the like at intervals of a
suitable width and thickness for the purpose. The outer ends of the strips pass
through slits to correspond, in that part of the outer cover coming flush with the
upper edge of the wheel rim, or to a point opposite slots cut in the wheel rim as
the case may be; and one side of such strips carry a buckle shaped to fit the
curvature of the rim, and both ends are buckled round the rim.
The wheel rim is preferably half circular in section, but may be specially shaped
if desired, and by buckling the pneumatic tyre thereto at intervals round the wheel
and then inflating the tyre it cannot shift in any way, and no unsightly canvas
covers the rim and the tedious operation as in the "Dunlop" tyre of having to pull
off or lay open the canvas is dispensed with. The valve is also reduced from the
ordinary blow up valves now in use. And the invention will be found of great
utility for all kinds of racing wheels.

I, HENRY JAMES CREESE of No. 50 Chester Street Leicester in the County
of Leicester 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 :-

page_text: tyres of the pneumatic type having a block end or straight air tube of the ordinary
kind surrounded by a canvas bag protected by a sheet rubber cover.
The object of my invention is to facilitate the removal of the tyre and the air
tube when the latter is punctured or deflated, and a simple means of again com-
pleting the tyre and securing it to the wheel rim. Or it can be wholly removed
therefrom in a few minutes when desired.
It is well known that in cycles or sulky's made for racing, the race has often to
be given up through collapse of the air tube owing to the considerable time it takes
to put a duplicate tube in or repair the puncture. I desire to obviate this by
providing means whereby a duplicate tube can be put in and blown up to replace
another in a much shorter time than in which it can now be accomplished.
That my invention may be well understood reference is made to the accompanying
drawing in which,
Figure 1 is a view from the underside of the tyre showing the laced man-hole.
Figure 2 is a side view of the tyre, part of the canvas bag, and outer cover being
torn away, to show a protecting sheath of canvas to protect the laced man-hole, and
to obviate the cutting of the inner tube, and Figure 3 is a sectional view of the
tyre forming the subject of this invention.
All letters of references refer to like parts in the several figures.
To carry out my invention I construct the detachable tyre in the following
manner
66
I use as before stated a block end or straight air tube A which is secured by ties
in the ordinary_way as seen in dotted line a Figure 2." This is surrounded by
the canvas bag B, which is protected and thickened by a strip or strips of canvas b,
stuck upon the tread portion by solution, the outer surface of this canvas bag is
then coated with solution to receive the outer sheet rubber cover C, a slit is then
made near the valve, to form the man hole D, of any convenient length, holes are
then made at intervals on either side of the man hole to receive the lace or laces E,
the said holes may be either eyeletted or not. Before securing the air-tube A,
I slip thereon a protecting sheath of canvas F, and move it over the tie tapes a
seen in Figure 2," this protects the air tube from pressure upon the laces.
man hole is then laced up, the tyre put upon the rim, the valve G secured
and then blown up when it is secure upon the rim H which is by preference of
section "as seen in Figure 3." Or the ordinary rims can be employed and
the tyre solutioned thereto if desirable.

as
The
To enable a person to get at the air tube quickly upon deflation the tyre is
released from the rim, the valve is released, the lacing of the man hole D is relieved,
the protecting sheath F moved along the air tube, when both can be taken out of
the canvas bag B. Upon the puncture being repaired it can be again inserted, or a
duplicate put in the canvas bag instead.
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 :
For cycle or other wheel rims a detachable tyre constructed having a canvas,
bag solutioned to an outer sheet rubber cover, the canvas bag provided with a laced
man-hole, and a protecting sheath to take the pressure off the laced man-hole.
Substantially as and for the purpose hereinbefore described and set forth.
