PROVISIONAL SPECIFICATION.
Improvements in Tyres for the Wheels of Road Vehicles.
I STANLEY BETJEMANN 21 Agate Road Hammersmith Mechanician do hereby
declare the nature of this invention to be as follows:-
The object of this invention is to provide an improved silent tyre for the wheels
of road vehicles.
To effect this I tyre the wheel with a metal tyre, having a channel in the face of
it to receive a noiseless tyre consisting of thicknesses of leather, or india rubber and
leather or other material instead of leather, so fastened together, as not to be clastic
in the longitudinal direction and therefore not liable to stretch and pull out of the
channel.

COMPLETE SPECIFICATION.
Improvements in Tyres for the Wheels of Road Vehicles.
I, STANLEY BETJEMANN of 21 Agate Road Hammersmith County of London
Mechanician 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 :-
The object of this invention is to provide an improved silent tyre for road
vehicles.
For this purpose the wheel is shod with a grooved or channelled metal tyre, which
is filled with a silent tyre consisting of thicknesses of leather sewn or riveted together
in any convenient manner to form a mass of sufficient thickness to project any
required distance outside the groove or channel to form a wearing surface.
At the bottom of the groove or channel I place a thickness of india rubber on
which the leather rests, to negative the vibration. This thickness of india rubber
must be a little narrower than the groove or channel so as to allow of its expansion
under the concussion.
The leather fits closely round inside the groove or channel and may be fixed to
prevent its coming out by bolts or screws at intervals, passing through holes in the
leather and metal tyres into the wood felloe, the holes in the leather tyre being
deeply countersunk, so that the bolts or screws may have no part in the wear on
the road surface. The countersunk holes should be plugged with leather or cement.
For cycle tyres 1 propose to use a deep U rim, and for elasticity to put one large
and two smaller cords of solid rubber in the groove or channel for the leather to
rest on, as shown in Fig. 2.
The accompanying drawings will clearly explain the working of my invention-the
sections being about the full size for ordinary carriages, cabs and such vehicles.

thickness of rubber on which the thicknesses of leather D. D. D. D. (fastened
together by the stitches or rivets E. E.) rest. F. is one of the screws or bolts
securing the leather tyre in the grooved metal one.

tyre C. rests. D. D. are the rivets or stitches.

page_text: 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. A leather tyre for road vehicles made of thicknesses of leather substantially
as described and shown in the Specification and drawings.
2. The placing of india rubber under the leather tyre, substantially as described
and shown.
3. The making a tyre for cycles substantially as described and shown..
