PROVISIONAL SPECIFICATION.
Improved Appliances or Means for Securing Resilient Tyres on Road
Vehicle Wheels.
I, JOHN HENRY GLEW, of Albion Works, Valmar Road, Camberwell, County
of London, Wheel Manufacturer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improved appliances or means for securing resilient
tyres on road vehicle wheels.
For the purpose of this invention, I take any ordinary U shape of metal as
the sheathing or tyre proper to a rubber lined rim which with the wooden felloe
constitute a tyre of a wheel. The sheathing may be in length and bent to
circular form. Each end of this length I prepare with a slot and a widened
hole from each side of the slot for the reception of a key of tapered wedge forma-
tion to be passed into the adjoining slots and holes of the two ends when brought
together. to enable the ends to be drawn tight and close up. This wedge, or the
tail portion only, is sufficiently deep to pass through the rubber liner and the
rim in which holes are also prepared, the tail piece being perforated for the
reception of a bolt passed into the felloe crosswise and the tail piece respectively,
the perforation being preferably of elongated form for slight play while the
vehicle is travelling.
This is a simple mode of preventing resilient tyres of road vehicles from
creeping as well as a ready means for securing the sheathing to the wheel, but
there may be an additional slot in some other part of the sheathing for a plain
wedge or other key to be similarly bolted to divide or reduce any strain that
might be thrown upon wedge and tightening key before referred to.

Improved Appliances or Means for Securing Resilient Tyres on Road
Vehicle Wheels.
I, JOHN HENRY GLEW, of Albion Works, Valmar Road, Camberwell, County
of London, Wheel Manufacturer, 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:-
This invention relates to improved appliances or means for securing resilient
tyres on road vehicle wheels.

page_text: For the purpose of this invention, I take an ordinary U shape of metal as
the sheathing or tyre proper to a rubber lined rim which with a metal base and
the wooden felloe constitute a tyre of a wheel. The sheathing may be in length
and bent to circular form. Each end of this length I prepare with a slot and
a widened hole from each side of the slot for the reception of a key of tapered
wedge formation to be passed into the adjoining slots and holes of the two ends
when brought together to enable the ends to be drawn tight and close up. The
tail portion of this wedge is sufficiently deep to pass through the rubber liner
and the rim and felloe with a socket, the tail piece being perforated for the
reception of a bolt passed into the felloe crosswise the socket and the tail piece
respectively, the perforation is of elongated form to allow for slight play while
the wheel is travelling.
This is a simple mode of preventing resilient tyres of road vehicles from
creeping as well as a ready means for securing the sheathing to the wheel, but
there may be an additional slot in some other part of the sheathing for a plain
wedge or other key to be similarly bolted to divide or reduce any strain that
might be thrown upon wedge and tightening key before referred to.
My invention is clearly represented on the annexed drawings.

section.
Figure 2 part sectional elevation of that part of a wheel where the two ends
of a sheathing tyre meet and having the key in position.
Figure 3 plan of same.
Figure 4 cross section of rim and rubber and showing one end of the sheathing.
Figure 5 part sectional elevation of, say, the opposite half circumference
of a tyre of my invention.
Figure 6 plan, and Figure 7 cross section.
Figures 8 and 9 face view and edge view of key for same.
Referring to Figures 1, 2, and 3. A, wood felloe. B, metal socket dropped
in slot formed in the felloe. C, rim of trough or gutter shaped metal bar rolled
or bent into ring shape and welded up in the ordinary manner shrunk on and
secured to felloe A by bolts or rivets D. E, rubber liner moulded to shape to
fit into the channel groove of the rim and having groove F in its base to allow
for compression of the rubber due to the load carried in a vehicle to which a
wheel having the invention applied is fitted.
G, shield or tread ring also of trough or gutter shape but reversed in position
to that of the rim C for the wings or webs H to lodge within and be guided by
the wings or webs I, I, of the rim C, and also to prevent side play should the
wheel strike or be forced sideways against the kerb of a roadway. J, slot in
rubber liner E.K, K, steps in rubber liner. L, L, notches in ends of tread
or shield G. M, key for fitting the key ways or slots in shield G and rubber
liner E and bearing on steps K, K, said key also fits slot in socket B where,
by a cross bolt N passed through the felloe A, the several parts are held in
place, the hole P in the key M is elongated vertically to permit of compression
of the rubber liner E due to the load carried as that part of the wheel comes in
contact with the ground in its revolution.
The head Q of the key M is shaped circumferentially to that of the wheel
shield G to be flush therewith and each end of the head is cone shaped to fit
corresponding openings near the meeting ends R, R, of the shield G, the
extreme ends of the shield having a notch L for the plain part of the key head
to lodge in.
In practice, the shield is bent to fit over the moulded rubber liner E and as
the meeting ends R, R, of the shield are brought together and the key M in-
serted, the cone shaped ends T, T, fit the corresponding shaped openings of the
shield G and draw and retain the meeting ends in close contact and so preserve
the continuity of the shield G.
I have described the invention as if a single shield only were fitted over

page_text: the rubber liner, but it may be in two or more strips bent to fit the rotundity
of the wheel as tread strips thereto, in which case each end of each strip would
be similarly prepared and additional keys U employed in the same manner for
retaining them on the wheel. If a single ring shield only be provided, the
shield G, the rubber liner E, and the felloe A with a socket B can be prepared
for the reception of a plain flat stemmed key U, as represented at Figures 6
and 7 of the drawings, in which case I extend the head of the key U, as at V, V,
to fit the cone shaped end of the slot in the shield G, or said slot may have
chamfered sides for the reception of the head of the key shown at Figures 8
and 9.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. A wheel tyre for a road vehicle, consisting of wood felloe A, trough shaped
base ring C surrounding the felloe, rubber liner Ein said base, shield G with
webs H fitting within the webs I of the base C, cone shaped holes near the
meeting ends R, R, of said shield for corresponding shaped ends T, T, of a
key M, notches L, L, in extreme ends R, R, of shield G for flat part Q of key
head, cross bolt N, all arranged as specified.
2. A wheel tyre for a road vehicle consisting of wood felloe A, socket B,
base ring C, rubber liner E, shield G, with webs H within webs I, I, of base
ring C, slot through felloe A, rubber liner E, key M, cross bolt N in vertically
elongated hole P of key M, cone shaped ends T, T, of key head Q, cone shaped
openings next to notches of shield ends R R, all as specified.
3. The combination with a felloe with socket, and a base with webs, of a liner,
a shield with webs extending oppositely to those of the base, a wedge headed
key passed through slots in the shield, liner and base, and through the socket
of the felloe, and a cross bolt passed through a hole in the said key, substantially
as described.
