PROVISIONAL SPECIFICATION.
Improvements in and connected with Pneumatic Tyres of Cycles.
I ALFRED THOMAS ANDREWS 145 Tennant Street Birmingham in the County
of Warwick Machinest do hereby declare the nature of this invention to be as
follows:-
My improvement is a method of secureing the tyre to rim by means of a leather
or rubber band of suitable shape placed over a tubular tyre made of leather or
rubber or other suitable material provided with a small injecting pipe & back valve.
The band to be provided with hooks or other suitable fastenings & fixed on the
band at suitable distances apart to hook on nipples or spokes of the wheel & by
placeing the tubular tyre on rim of wheel & placeing the band over it then placeing
the hooks on nipples or spokes an air pump is applied & the tubular tyre propperly
inflated it will be seen that the pressure will hold the tyre on secure & in case of
repairs being necessary to the wheel by letting the air out it will be easy to get the
spokes in or out as required in case the hooks do not bed down on the rim I perpose
useing a nipple screwed outside provided with a nut to hold the hook down. In
case there are not sufficsent spokes I perpose useing a suitable stud between the
spokes fixed in the rim.

COMPLETE SPECIFICATION.
Improvements in and connected with Pneumatic Tyres of Cycles.
1, ALFRED THOMAS ANDREWS, of 145 Tennant Street, Birmingham, do hereby
declare the nature of my said invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
My improvement is a method of securing the tyre to rim by means of a leather
or rubber band of suitable shape placed over a tubular tyre made of leather or
rubber or other suitable material provided with a small injecting pipe and back
valve the band to be provided with hooks or other suitable fastenings and fixed on
the band at suitable distances apart to hook on nipples or spokes of the wheel and
by placing the tubular tyre on rim of wheel and placing the band over it then
placing the hooks on nipples or spokes an air pump is applied and the tubular tyre
properly inflated it will be seen that the pressure will hold the tyre on secure and
in case of repairs being necessary to the wheel by letting the air out it will be
casy to get the spokes in or out as required in case the hooks do not bed down on
the rim I purpose using a nipple screwed outside provided with a nut to hold
the hook down. In case there are not sufficient spokes I purpose using a suitable
stud between the spokes fixed in the rim.
And in order that this my said invention may be more fully understood I shall
now proceed more fully to describe the same and for that purpose I shall refer to
the figures on the sheet of drawings hereunto annexed, the same letters of
reference indicating corresponding parts throughout the figures.
Fig. 1, is a longitudinal view in section shewing the metallic rim with spokes
thereto, the elastic tubular tyre, and band, and means employed for securing said
band and holding said parts together.
Fig. 2. is a view cross-section of the same, one part of band detached or
unfastened from the metallic rim, to more clearly illustrate.

page_text: a, is the band of a required shape placed over the pneumatic elastic tubular
tyre b, provided with metallic hooks e, at or near the edge of u, and at a suitable
distance apart, these hooks c, are fixed or connected by passing through metallic
eyeletted holes d, as shewn in Fig. 2-e, is the metallic rim, . are spokes affixed in
the usual manner to e, y, are studs, also affixed to e, between the spokes f
By reference to Fig. 1 I illustrate my mode of fastening, is a plain nipple
with, the hooks e, engaged thereon, is the screwed nipple with hook c, and nut j,
for holding, down the remaining spoke, shews the hooks c. thereon without a
nipple. The studs g, shew the eyeletted hole d, and hooks thereon.
When the pneumatic tyre or elastic tube b, is placed upon the rim e and the
band or cover a, is placed thereon, and the hooks c, of a, arranged upon hif, or g,
or its equivalent d, engaged upon 9, and by the application of an air pump the
tubular tyre b, is distended and also the band a, and thus the fastening is more
securely effected.
It will be perceived that if any accident should arise to or in connection with
the spokes or rim the air could be released and the band and tube removed with
ease for the repairing.
I would observe in conclusion that I do not limit myself to the precise details
or arrangement of parts as various modifications may be made without departing
essentially from the principle of the said 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 :-
For "Improvements in and connected with pneumatic tyres of cycles."
The combination of a band or cover with hooks, in eyeletted holes, such hooks
engaging upon the nipples of the spokes connected with the rim (forming a wheel
for a cycle) either plain or screwed, or upon the spoke direct, or upon the studs,
connected to the rim between the said spokes, substantially as and for the purpose
above set forth in the foregoing Specification and shewn on the accompanying
sheet of drawings.
