PROVISIONAL SPECIFICATION
Improvements in Wheels and Pneumatic Tyres for Cycles, and in
Driving Chains and Chain Wheels, and in Spring Saddles or
Seats for same.
I TIMOTHY MURPHY of Number 74 O'Connell Street Clonmel in the County of
Tipperary Agricultural Engineer do hereby declare the nature of this invention to
be as follows:-
At Drawing Fig. 1. is shown a cross section of rim and cover of said Invention,
at R is shewn the rim, B is the cover within which the air tube is placed. Said
air tube is inflated by means of a valve inserted through the rim. The said cover B
is kept in position on said rim when inflated by means of loops or bands, which are
composed of steel or other metal and are flat or may be tubular or other form or
they may be wood, which encircle it at the part shewn at F, and the other said band
at E. Said bands are fastened to said parts of cover all around the circumference
by means of rivets or other fastenings, or said bands may be enclosed in said canvas
cover. At a Fig. 2 is shewn another mode of attaching said bands in which case
the band is doubled and encased on the cover as shewn at a and rivetted to the
cover as shewn at O Fig. 2 the band is bent on edge and doubled or looped on the
cover all around and fastened in a similar way as described at a. Said bands are
made endless or continuous or the ends may be rivetted together or otherwise
attached.
At drawing Fig. 3 is shewn a side view of said rim in which there is a portion of
the flange taken off for the purpose of passing the hoops or bands which are fastened
to the said cover on to the said rim as shewn at Fig. 1. and when said cover is so
placed on said rim it is kept on by means of a segment P shewn at Fig. 4. Said
segment is placed on said rim inside. The low flange, as shewn at t Fig. 3 and the
two projections or hooks formed on the ends of said segment A A fits into the holes
formed at A A Fig. 3 and as so placed it will resist the pressure of the air against
the said cover or said low flange formed at t Fig. 3 may be dispensed with in which
case the projection stops formed on said segment at A fits into corresponding slits
formed in said rim at a a Fig. 3 thereby causing said segment to resist the pressure
of the said air tube against said cover, or the whole of said flange t Fig. 3 may be
removed in which case there are any desired number of slits formed in the said rim all
around as shewn at a a Fig. 3 and at a cross section of said rim shewn at A A Fig. 6
and into these said slits a corresponding number of projecting stops which are
formed on the flange H at I Fig. 5 are made to fit when said flange is placed in on
said rin and when so placed it is only necessary to slightly move the said flange H
Fig. 5 around when the said projecting stops I will move into slits shewn at A A. Fig. 6
when it will resist the pressure of the cover and when it is desired to remove said
flange it is removed back out of the slits when it comes off, or said flange shown at
Fig. 5 may be jointed at M and as so jointed is sprung in over the low flange formed

I TIMOTHY MURPHY of Number 74 O'Connell Street Clonmel in the County of
Tipperary Agricultural 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 :-
This invention relates to pneumatic tyres, driving chains and chain wheels, and
spring saddles or seats for cycles or velocipedes, and it consists of certain improve-
ments hereinafter more particularly specified.
In the accompanying drawing Figures 1, 2, 3, 4 and 5 Sheet No. 1 illustrate the
first part of my invention, namely that relating to pneumatic tyres.
Figures 6 and 7 Sheet No. 2 illustrate the second part of my invention, namely,
that relating to driving chains and chain wheels, and
Figure 8 Sheet No. 2, and Figures 9 and 10 Sheet No. 3 illustrate the last part
of my invention, namely that relating to spring saddles or seats.
Throughont the views similar parts are marked with like letters of reference.
Referring to Figures 1 to 5 inclusive, A. designates the cover of the pneumatic
tyre which is made of rubber reinforced with canvas in the well-known manner, and
is adapted to contain within or to cover an air tube of the ordinary type provided
with any suitable form of valve for inflation and deflation.
The cover A is kept in position on the wheel rim B when inflated by means of
hoops or bands such as C which may be made of steel or any other suitable metal
or material. These bands may be either flat in cross section as shown by Figure 1,
or they may be of tubular or any other suitable form. The bands C are fastened to
the edges of the cover A by means of rivets or other fastenings or they may bo
enclosed in pockets in the edges of the cover.
An alternative method of attaching the bands to the cover is to double them over
the edges of the cover A as shown by Figure 2. As a further modification the
edges a of the cover A may be enlarged and the bands C shaped to fit around them
as shown by Figure 3. In this construction the band C may be made just to cover
the enlarged edges a of the cover A as shown on the left hand edge of the cover in
Figure 3 or they may be made to extend slightly beyond the edges as shown on the
right hand edge of the cover A in Figure 3.
The bands C may be either endless in the form of hoops, or they may be made in
lengths having their ends rivetted or otherwise fixed together. Or as an alternative
construction the ends of the bands may be provided with any suitable device such
as a right and left hand threaded nut for expanding or contracting the band for
the purpose of mounting or dismounting the tyre.
The rim of the wheel B has a portion of one of its flanges b cut away as shown by
Figure 4, the said cut away portion being made up by a section B1 shown in Figure 5,
the said section being adapted to be screwed or bolted to the flange band to be
supported by means of projecting stops 61 adapted to engage with slits or slots bin
the base of the rim B, thereby enabling the section B to receive the outward
pressure of the cover of the tyre when the air tube is inflated.
