PROVISIONAL SPECIFICATION.
Improved Means for Attaching Pneumatic Tyres to the Rims
of Wheels.
I, WILLIAM EDWARD KAY, of Gowanbank Clarkston, Busby near Glasgow,
Chemist, do hereby declare the nature of this invention to be as follows:-
The improvements relate to means for attaching pneumatic tyres to the rims of
wheels, and apply to that class wherein the sheath or cover of the tube is provided
with beaded or thickened edges which take into a groove or grooves in the rim, and
are held therein by means of a sliding band or bands; and the object of the
improvements is to provide better and more effectual and ready mechanical means
for sliding such band or bands into and out of the locking position.
To effect this, and to accomplish my improvements, I provide a rim of any
suitable shape in cross section, which rim has formed therein, and along the
circumference thereof, either one or two recesses or grooves, into which the beaded
edges of the sheath or cover can take.
I then provide a band or bands for keeping such beaded edges within the recesses
or grooves, as will be well understood.
But the means for actuating these bands, and which mainly constitute my
improvements, consist in providing the sliding band or bands with slots or recesses,
at suitable intervals in the circumference, which slots or recesses are cut or formed
at an angle, or as an angular curve. Attached to the rim of the wheel are pins or
studs, fixed at intervals, corresponding to and engaging with the angular slots or
curves aforesaid, in such manner that, by the operator moving the band or bands
in the direction of the circumference, the band or bands are pressed outwards or
sideways, in an oblique direction, by the angular slots, recesses or curves formed
therein or thereon.
In a similar manner the studs or pins may be attached to the band or bands, and
the slots, recesses or curves cut or formed in or on the rim, thus taking the
arrangement in reverse.
One or more of the pins or studs may pass through the rim, to facilitate the
operative movement, and be fitted with a nut or nuts to form a locking device for
the band or bands, or other means may be employed for securing the band or bands
in the required positions, and further variations in detail may be made without
departing from the peculiar character of the invention.

Improved Means for Attaching Pneumatic Tyres to the Rims

1, WILLIAM EDWARD KAY, of Gowanbank, Clarkston, Busby, near Glasgow,
Chemist, 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: des state
"
The improvements relate to means for attaching pneumatic tyres to the rims of

page_text: wheels, and apply to that class wherein the sheath or cover of the tube is provided
with beaded or thickened edges which take into a groove. or grooves in the rim,
and are held therein by means of a sliding: band or bands; and the object of the
improvements is to provide better and more effectual and ready mechanical means
for sliding such band or bands into and out of the locking position.
To effect this, and to accomplish my improvements, I provide a rim of any
suitable shape in cross section, which rim has formed therein, and along the
circumference thereof, either one or two recesses or grooves, into which. the beaded
edges of the sheath or cover can take. I then provide a band or bands for keeping
such beaded edges within the recesses or grooves, as will be well understood. But
the means for actuating these bands, and which mainly constitute my improvements,
consist in providing the sliding band or bands,-which are preferably endless-
with slots or recesses, at suitable intervals in the circumference, which slots or
recesses are cut or formed at an angle, or as an angular curve. Attached to the
rim of the wheel are pins or studs, fixed at intervals, corresponding to and engaging
with the angular slots or curves aforesaid, in such manner that by the operator
moving the band or bande in the direction of the circumference, the band or bands
are pressed outwards or sideways, in an oblique direction, by the angular slots,
recesses or curves formed therein or thereon.
In a similar manner, the studs or pins may be attached to the band or bands, and
the slots, recesses or curves cut or formed in or on the rim, thus taking the
arrangement in reverse.
One or more of the pins or studs may pass through the rim, to facilitate the
operative movement, and be fitted with a nut or nuts to form a locking device for
the band or bands, or other means may be employed for securing the band or bands
in the required positions.
But that the improvements may be better understood, I will, with the aid of the
accompanying drawings, proceed more fully to describe means employed by me.
Fig. 1. is a cross section of one form of tyre, provided with apparatus according
to my improvements and Fig. 3. is a reverse plan of the rim and bands, while
Fig. 5. is a sectional plan of the tyre.
Fig. 2. is a cross section of another form of tyre, and Figs. 4. and 6. are a
longitudinal section, and a sectional plan thereof, respectively.
In all views, the inner air tube is omitted for the sake of clearness.
The same letters indicate corresponding parts wherever they occur.
a. a. are the outer covers or sheaths of the tyres, provided with beaded or
thickened edges a¹ a', which fit into the grooves or recesses of the
rims b. b.
c. c. are the locking bands encircling the rim; two such bands being employed in
the case of Figs. 1. 3. and 5., while only one is shewn in Figs. 2. 4. and 6.
d. d. are the pins or studs attached, in this case, to the rims, though the
arrangement may be reversed,-which studs project within slots c' c' in the bands;
and e. e. are the pins or studs attached to the bands, and projecting through
openings in the rims, such pins or studs being provided with plates e e' and
nuts or thumbscrews e e, for securing the bands in position.
The plates el el may be either as shewn in the drawings, or may be large enough
to cover the whole of the slot connected with each, or one plate may be employed
to cover both slots, thereby preventing the access of water or dirt; and these plates
may be sunk in recesses, by which means the bands are not liable to be accidentally
moved even when the nuts of the retaining pins become partially loosened.
The openings in the rims, to allow free movement of the pins or studs e., may
be of any convenient shape or size, although in the drawings they are shewn as
slots, taking a similar direction to the slots in the bands.
It will be seen that, as the pin or stud e, in each case, is moved in the direction

page_text: of the tyre circumference, the band to which it is connected is moved also, and, the
slots c c being engaged with the fixed pins d. d. such band is guided or forced
inwards or outwards, locking or unlocking the outer cover or sheath, as the
case may be.
In practice, the actuating pins e. inay be at any convenient point in the
circumference of the tyre. In the case of two bands being employed, as in Figs. 1.
3. and 5., such bands are completely locked and unlocked at the extremities of their
side motion; but in the case of one band, as in Figs. 2. 4. and 6., the same is in the
locking position when at or about the centre of its path of lateral motion, and is
moved to either side to unlock, as required.
The valve requisite for inflation purposes may be arranged to take the place of
or correspond with one of the pins, or otherwise.
The bands may be covered with canvas, or other material, for better protection
against damage to the air-tube, rust, or other detrimental occurrences, and
variations in detail, such as in the number of systems of slots or openings, and pins
or studs employed throughout the circumference of the wheel, the shape of the rim,
and the number and form of the recesses therein, and the method of attaching the
pins or studs to the rims, or to the band or bands; as well as in the design and
material of the various parts, may be made without departing from the peculiar
character of the invention.
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 :-
1. In means for attaching pneumatic tyres to the rims of wheels, a band or bands
for locking the outer sheath or cover to the rim, which are guided by means of
pins or studs fixed to the rim and taking into angular slots in the band or bands, or
vice-versa, for the purpose and in manner substantially as herein shewn and
described.
2. In means for attaching pneumatic tyres to the rims of wheels, a band or bands
for locking the outer sheath or cover to the rim, capable of being actuated by
means of pins or studs projecting through openings in the rim, of the character and
for the purpose and in manner substantially as herein shewn and described.
