:-
Improvements in the tyres and rinis of carriages and velocipedes and in attaching
the same.
I form my carriage or other rims to completely enclose a pneumatic
tyre on three sides thereof being preferably rectangular, horse-shoe, or U-shaped,
and to envelope a pneumatic tyre or air-chamber on three-fourths of its sectional
circumference, the outer periphery being left open to the road and protected
therefrom by means of several parts of canvas and rubber rolled hard under pressure,
or prepared hide, or of resin cloth to protect it from puncture, or a steel protector
may be formed of several pieces of steel united on an elastic or partly clastic
ribbon or band, which will permit of its being readily placed over the tyre or air-
tube; this band may be gripped on each side by a small portion of the rim being
turned inwards.
A wearing piece of rubber or other suitable material is now placed over this and
shaped to suit the rim, whether the said rim be rectangular, horse-shoe, or U-shape.
in section; this wearing piece is preferably half round in section with a flange
piece on each side that is gripped by the rim at the sides as well as the protector
before mentioned. Or the air-tube may be protected by the wearing piece being
made of, or united to a metallic substance of any pattern, solid or hollow.
These rims may be corrugated at the sides, or with a corrugation or flange piece
to protect it from wear against the kerb and also to strengthen it.
When a round tyre, in section; is to be attached to these rims, I provide them.
with a concave surface uniting them on the outer periphery; and I attach a
pneumatic tyre cover on the outside of the rim by means of a flat or other ring
attached to the cover and fitting into a groove provided for it at the sides of the
rim, and covered by an outer band, preferably half round in section, either solid or
hollow, that serves to secure the tyre and also answers as a wearing piece against
the kerb; or the, tyre may be first attached by studs fitting into the sides of the
rim and secured by the band or ring, or the cover may be fastened direct into this
band when hollow. I secure the tyres to wooden wheels in the same manner,.
suitable slots or holes being provided in the felloes inside the ordinary iron rim to
which the pneumatic tyre is secured.
When I fasten the tyre or cover direct into the side piece or band before
mentioned I provide it with lugs, in which I have holes or slots and these may be
made oval or key-hole shape to fasten it to the felloes, so that on moving the ring

page_text: round either way the tyre may be locked or unlocked, one screw securing the same;
when required to use the wheels without pneumatic tyres it is only necessary to
take out these screws and push the bands round in a circular manner to release the
tyres.
I sometimes form my rims of a flatter description, the hollow or concave portion
touching the inner or rectangular part so as to have a double thickness of metal for
the spokes and nipples.

and in Attaching the same.
I, JAMES HAROLD BARRY, of 4 Cadogan Terrace, Victoria Park in the County
of Middlesex, 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 :-
My invention relates to improvements in the tyres and rims of carriages and
velocipedes and in attaching the same to the wheels thereof and it consists in
enclosing a pneumatic tyre within a hollow metallic rim either of rectangular,
horse-shoe or other suitable section having its outer periphery partly cut away and
left open to the road, a protecting cover being provided on the outer circumference
formed either of canvas and rubber rolled hard, of resin cloth, or of a number of
steel plates joined together upon an elastic band secured upon the rim in the manner
hereafter described, the said metallic rim having a wearing piece of rubber or other
suitable material arranged to fit its outer periphery.
In order that my invention may be more clearly understood reference is had to
the accompanying drawings upon which :-
Figure 1 is a transverse section of a tyre constructed according to my invention
and fitted with wearing piece, steel band, and rubber cover.
Figure 2 illustrates an alternative method of attaching the steel band, the rubber
wearing piece being fastened on to the band.
Figure 3 is a modification of the arrangement shewn on Fig. 1, a hollow metal
wearing piece being attached to a solid rubber tyre.
Figure 4 shews a solid metal wearing piece for use on a rim of the form shewn on
Fig. 3.
Figure 5 is a transverse section of a tyre as constructed for a pneumatic tyre of
circular section.
Figure 6 shows the application of my improved tyre to an ordinary felloe,
Figure 7 is a side elevation of a band provided with slots forming a bayonet
catch.
Figures 8 and 9 shew modifications in the form of wearing piece and rim
respectively.
In carrying out my invention I construct a hollow metallic rim A preferably of
a quadrilateral section as shewn on Figure 1, enclosing on three sides a pneumatic
tyre B and having its fourth side or outer periphery partially cut away or left open
to the road for a portion of its width. The rim A may either be corrugated at the
sides or provided with a flange piece C for the purpose of strengthening it and of
protecting it from wear against the kerb, as shewn on Figure 3. To protect the
pneumatic tyre B from puncture or other injury in use, I provide upon the periphery
of the metallic rim A so as to cover the open part thereof, a protector D formed
either of several strips of canvas and rubber rolled hard, or of prepared hide or
resin cloth or other suitable material; or I may form the protector D of several

page_text: pieces or plates of steel united upon an elastic band (as shewn on Fig. 2). This
band may be secured on the rim A by inserting its edges & under an inwardly turned
portion a of the rim A (see Fig. 2) which thus grips the band.
Over the band or protector D is placed a wearing-piece of rubber or other suitable
material preferably of half round section E and adapted to fit the rim or felloe,
a flange e being formed upon the wearing-piece E to engage or come in contact
with the inner faces of the re-entrant flanges a of the metallic rim A as shewn on
Figures 13 and 8.
I may arrange for a hollow metal wearing piece F to be attached to a solid
rubber tyre E as shewn on Fig. 3 or for a solid metal wearing-piece F to be used
(see Fig. 4) upon a rim of the form shewn on Figures 3 and 8.
In another arrangement illustrated on Figure 5 I form the inner surface of the
metallic rim A concave in order to receive a pneumatic tyre B of circular section
in which case in lieu of a flanged wearing-piece as previously described, I insert
a band G and enclose the same within an external cover L of canvas or other
suitable material which is attached to the rim A by means of ringa provided on the
cover L and arranged to fit into grooves formed at the sides of the rin A for that
purpose. This cover is secured in position by means of solid or hollow metallic
bands H preferably of half round section.
Or the tyre cover L may be secured by means of rings to studs fixed on the
outside of the rim A or by equivalent devices.
In applying my improved tyre to an ordinary or wooden felloe, I secure the
pneumatic tube B upon the outer periphery thereof by means of a cover L attached
by similar devices to those above described to the sides of the felloes for which
purpose suitable grooves are formed in the latter, inside the ordinary iron rim as
shewn on Fig. 6.
When the tyre cover L is directly attached to a ring or circular band H secured
by means of studs h at the sides of the rim or felloe I form oval or key hole shaped
slots i in the band whereby on moving the latter round in one direction or the other
the tyre cover L may be locked or unlocked without removing the studs, (see Fig. 7)
a screw K being provided to retain the band H in its locked position.
Figure 8 represents an alternative arrangement of rim and tyre in which the
tyre cover is dispensed with.
If desired I may construct the hollow metallic rim A with the inner concave part
in contact with the sides of the outer or rectangular part, as shewn in Figure 9,
thereby obtaining a double thickness of metal in which to secure the ends of the
spokes.
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. The combination with a hollow metallic rim having a slot or central opening
on its outer periphery, of an elastic band or protector and a rubber tyre flanged or
otherwise, as and for the
purposes described.
2. The combination with a hollow metallic rim and rubber tyre, of a solid or
hollow metallic wearing piece for the purposes described and as illustrated on
Figures 3 and 4.
3. In rims for wheels the use of circular metallic bands or side pieces arranged
movably upon studs secured upon the sides of the rim or felloe or equivalent devices
for the purpose of securing a tyre-cover, substantially as herein described with
reference to the accompanying drawings.
