THOMAS WILSON ROBERTSON 88 Alfred Terrace Mountpottinger Road
Belfast Mechanical Engineer do hereby declare the nature of this invention to be
as follows:-
It is the addition of two projections to the edges of the rim of a wheel in which
are formed either perforations eyelets or hooks as desired for the attachment of a
resilient tyre, for instance india rubber or canvas or a combination of both.
The edges of the resilient tyre to be attached may be made in a variety of forms
to suit the desired effect, such as cord ends projecting from the edges or perforations
made in the edges or hooks fastened to the edges of the resilient tyre so as to
correspond with the perforations eyelets or hooks of the rim which will enable the
attaching together, simple, even and secure.

COMPLETE SPECIFICATION.
An Improved Method of and Means for Attaching Pneumatic and
other Flexible Tyres to the Wheels of Velocipedes and other
Vehicles.
I, THOMAS WILSON ROBERTSON, Mechanical Engineer, of 184 Grosvenor
Street, Belfast, County Antrim, Ireland, late of 88 Alfred Terrace, Mount-
pottinger Road, Belfast, 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 :-
It is the addition of two projections to the edges of the rim of a wheel in which
are formed either perforations, eyelets or hooks, (as desired) for the attachment of
a resilient tyre, such as india-rubber or canvas or a combination of both.
The edges of the tyre to be attached may be made in a variety of forms to suit
the desired effect, such as the ends of cords projecting from the edges, or
perforations made along the edges, or hooks fastened to the edges of the resilient
tyre, so as to correspond with the perforations, eyelets or hooks of the rim, which
will enable the attaching together to be made simple, even and secure.
In order that this my invention may be more fully or readily understood I have
hereto attached drawings which I will now proceed to explain.
Fig. 1 represents on a reduced scale the outer portion of a resilient tyre showing
cords A, A, projecting from its edges for the purpose of passing through the holes
or eyelets B in rim C Figs. 2 & 5 and fastened by tying. These cords may be
interwoven and vulcanized in the cover.
Fig. 3 represents on a reduced scale the outer portion of a resilient tyre showing
a series of perforations along the edges to be passed over the hooks D of the rim Č
Fig. 4 & 6 enclosing the inner inflatable tube E Fig. 4.
Fig. 7 shows a method whereby cover Fig. 3 can be attached to rim Fig. 5 by
lacing with one or more cords passing continuously from hole to hole round the
wheel.

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 :-
1st. The attachment of the resilient tyre to the rim of the wheel by hooks passed
through holes in the edges of the tyre-cover substantially as described and shown
at Fig. 4.
2nd. The attachment of the resilient tyre to the rim of the wheel by passing
the ends of cords through holes made in the edges of the rim for that purpose,
the cords being woven or vulcanized into the cover as described and shown by
Figs. 1 & 2.
3rd. The attachment of a resilient tyre having a series of holes or eyelets along
the edges, to the rim of a wheel having a corresponding number of holes by lacing
together through said holes as seen by Fig. 7.
Dated this 11th day of September 1891.
