PROVISIONAL SPECIFICATION.
Improvements in Wheels for Velocipedes.
I ENOCH SILTBERG 12 Spurriergate York Watchmaker & Jeweller do hereby
declare the nature of this invention to be as follows:-
A. steel rim for bicycles and tricycles, about 14 in. wide, both edges of which are
turned over towards centre of wheel. An air tube of india rubber laid round the
rim provided with a valve & inflated. An outer covering of india rubber, on the
inside of which is glued a lining of canvas or cloth, which lining is turned over
the edges of the covering & glued on to the outside, 1 in. all round flat brass hooks
to be affixed along the edges of the outer covering 1 in. apart and hooked on to the
turned over part of the before mentioned rim.
An alternative scheme is a hollow rim with holes to receive the hooks as before.
A third scheme is to have brass eyelets along the edges, instead of hooks, and a
series of brass hooks rivetted along both sides of rim to button the eyelets on to.

COMPLETE SPECIFICATION.
Improvements in Wheels for Velocipedes.
I, EXOCH SILTBERG, of No. 12, Spurriergate, York, in the County of York,
Watchmaker and Jeweller do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
My invention relates to an improved rim or metal tyre for bicycles and tricycles,
affording a means for attachment of a pneumatic and flexible outer tyre, and
admitting of replacement or renewal of these when desirable, and also to provide
means for preventing the total disablement of the machine in the case of one of
said tyres being punctured or otherwise rendered inoperative.
In order that my invention may be clearly understood I have appended the
accompanying sheet of drawings in which
Figure 1 is a cross sectional view of the tyres and wheel, and Figure 2 a view
shewing the method of attachment thereof.
In carrying my invention into effect employ a steel rim A, Figure 1, both
edges of which are turned over and inwards towards the centre of the wheel. A
protective cushion B is preferably laid in the groove of the metal tyre A, and a
hollow air tube C laid over this, provided with a valve and inflated. A separate
outer covering E of india rubber or the like is lined with a protective covering D
Flat hooks Fof
of canvas or the like, glued or otherwise firmly attached to it.
brass or other metal are fixed along the edge of the covering D so that they may
be hooked over the edges of the metal tyre A, and thus hold the air tyre C and its
sheath E in position thereupon. I may, instead of providing turned edges upon the
tyre A, form holes therein, corresponding to the pitch of the hooks, so that said
hooks may engage therewith, or I may attach said books to the tyre A and fix
eyelets to the edges of the protective covering D.
Ι may attach the covering D to the sheath E in the form of an inner sheath with
strips or turned over flaps extending for a short distance up the sides, or may make
it in two pieces with a central seam.
The hooks are preferably formed upon, or stamped out of a bent frame, as shewn
by Figure 2, so that the upper edge is rounded so as not to cut the canvas or like

page_text: material when it is stitched round it.
The hooks F are also preferably caused to
project through the covering, the metal frame thus being enclosed, and strongly
held by the stitched seam.
I may also employ stout wires instead of hooks, causing these to project at
intervals upon cach edge of the canvas cover, and engage with hooks or the like
upon the tyre, or, said wires being endless, and possessing elasticity may be sprung
under the metal tyre so as to engage with the grooves thereof and retain the whole
in position when inflated.
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 -
=
First. In an improved wheel for velocipedes, the combination of a curved metal
tyre A, air tyre C and protective sheath E with a canvas covering D provided with
hooks F to engage with the edges of A, substantially as, and for the purposes
herein described with reference to the appended drawings.
Second. In an improved wheel for velocipedes, the employment of holes in the
metal tyre A instead of turned edges, in combination with hooks attached to the
canvas cover D, surrounding the sheath E and air tyre C, substantially as herein
described.
Third. The modification of the device referred to in the preceding claim, by
attaching the hooks to the metal tyre A and eyelets on the cover D substantially
as herein described.
