Improvements in connection with Tyres and Wheels of
Velocipedes.
I, ENOCH SILTBERG, of No. 12 Spurriergate, in the City and County of York,
Watchmaker and Jeweller do hereby declare the nature of this invention to be as
follows:-
My invention relates to certain improvements in connection with the tyres and
wheels of velocipedes as described in the Specification of Letters Patent No. 9404
of A.D. 1891, and has for its object an alternative method of and means for
attaching the outer covering of the inflated tyre as therein described, to the rim or
metal tyre of the wheel.
In carrying my invention into effect I construct a metal tube of circular, square
or other cross section, in such a manner that the edges do not meet, thus forming a
continuous slot. Said tube is bent lengthways so as to form a circle approximately
coinciding with the metal tyre of the wheel. The ends, however are not joined by
soldering or the like, but are left free. The outside covering that surrounds the
pneumatic or inflated tyre is provided with a bead on both edges, made by sewing
or otherwise attaching a wire or cord to said edges. The outer covering being
joined so as to form a continuous band, a notch is cut through each edge at a given
point, so that the bead may be threaded through the bent tube before described,
the material forming the outer covering passing through the slot, formed by the
open edges of the tube. A tube being thus fitted to each edge of the outer
covering, in such a manner that the turned edge of said metal tyre fits within and.
practically fills the slot, the said outer covering may be placed in position so as to
surround and enclose the hollow tyre, thus firmly holding the said outer covering,
and the pneumatic or hollow tyre when the latter is expanded by inflation.
The tubes, therefore form metallic edges for the outer covering, the beaded
edges thereof being firmly retained within said tubes, since the slots are only
sufficiently wide to allow the fabric to pass.
In making the tubes I may in some cases turn the edges slightly outwards so that
the friction of the fabric within the slots may not rupture nor abrade the fibre
thereof, or I may use any equivalent means for guarding the edges of said slots, or
that part of the fabric or material forming the outer covering that passes through
said slots.
I do not confine myself to any particular method of making a projecting bead on
both edges of the outer covering, but may use an attached or formed bead of the
same fabric or material constituting said outer covering, or may insert any kind of
beading or attach such beading to the edges in any convenient way.

COMPLETE SPECIFICATION.
Improvements in connection with Tyres and Wheels of
Velocipedes.
I, ENOCH SILTBERG, of No. 12 Spurriergate, in the City and 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
5 ascertained in and by the following statement :—
My invention relates to certain improvements in connection with the tyres and

page_text: wheels of velocipedes, and has for its object a method of and means for attaching.
the outer covering of an inflated tyre to the rim or metal tyre of the wheel.
In carrying my invention into effect, I construct a metal tube of circular, square
or other cross section in such a manner that the edges do not meet, thus forming a
continuous slot. Said tube is bent lengthways so as to form a circle approximately
coinciding with the metal tyre of the wheel. The ends, however, are not joined by
soldering or the like but are left free. The outside covering that surrounds the
pneumatic or inflated tyre is provided with a bead on both edges made by sewing
or otherwise attaching a wire or cord to said edges. The outer covering being
joined so as to form a continuous band, a notch is cut through each edge at a given
point, so that the bead may be threaded through the bent tube before described,
the material forming the outer covering passing through the slot formed by the
open edges of the tube. A tube being thus fitted to each edge of the outer
covering in such a manner that the turned edge of said metal tyre fits within and
practically fills the slot, the said outer covering may be placed in position so as to
surround and enclose the hollow tyre, thus firmly holding the said outer covering,
and the pneumatic or hollow tyre when the latter is expanded by inflation.
The tubes, therefore form metallic edges for the outer covering, the beaded edges
thereof being firmly retained within said tubes, since the slots are only sufficiently
wide to allow the fabric to pass
In making the tubes I may in some cases turn the edges slightly outwards so
that the friction of the fabric within the slots may not rupture nor abrade the fibre
thereof, or I may use any equivalent means for guarding the edges of said slots, or
that part of the fabric or material forming the outer covering that passes through
said-slots.
I do not confine myself to any particular method of making a projecting bead on
both edges of the outer covering, but may use an attached or formed bead of the
same fabric or material constituting said outer covering, or may insert any kind of
beading or attach such beading to the edges in any convenient way.
And in order that my said invention may be fully understood I will proceed to
explain the same with reference to the accompanying drawing in which :-
Figure 1 represents a section of a pneumatic or air inflated tyre attached to the
rim of a wheel according to this invention.
Figures 2 and 3 are modifications of the rim and tyre also constructed according
to this invention.
Figures 45 and 6 are modifications of Figure 1 hereinafter referred to.
The same letters denote the same parts in all the figures.
Now according to this invention I construct a metal tube A of circular, square,
or other suitable cross section in such a manner that the edges thereof do not meet
thus forming a continuous slot in the tube which is bent lengthwise so as to form a 4
circle approximately of the same diameter as the rim of the wheel the ends of the
bent tubes are not joined together.
The outer protective covering B which partly envelopes the pneumatic or inflated
tube C is provided with a beading D on each edge which may be made by imbedding
a cord in the material of which the covering B is composed or by sewing or
otherwise attaching cord to the said edges, or which may be moulded in the material
itself. The outer covering B forms a continuous band, and each beading D is cut
through at one point to allow of the same being threaded through the bent tubes A
of which there is one on each side of the wheel.
The material forming the covering B passes through the slots formed by the open
edges of the tube.
A tube A is fitted to each edge of the covering B and the edges of the rim of
the wheel are turned over or otherwise formed to fit into and with the covering B
fill the slots or nearly so, that when the pneumatic tube C is inflated both it and
the outer covering B are firmly secured to the rim E of the wheel.
The tubes A Å form metallic edges for the covering B the beaded edges of
which are firmly retained within the said tubes as the slots are only of sufficient
