Improvements in Tyres for Wheels of Carriages or Vehicles of
every description.
HENRY HOLLICK 39 Smithford Street Coventry Warwickshire Carriage
Builder do hereby declare the nature of this invention to be as follows:-
-
This invention relates to the construction and arrangement of the tyres of
wheels for carriages or other vehicles whereby the elastic and noiseless advantages
of an india rubber tyre may be secured while the usual disadvantages.
viz., excessive wear and tear of india rubber-may be obviated, in a better manner'
than heretofore. It consists primarily of the application of an extra or outer
tyre or shield of steel and wood, manipulated as hereinafter mentioned, upon the
underneath india rubber tyre.
In carrying out my invention I should proceed somewhat thus :-The steel or
metal tyre (or felloe) of the wheel is suitably shaped at its outer circumference,
being more or less of a gutter form, its outer circumference being preferably
narrower. Around this steel or metal tyre (or felloe), is now placed an india
rubber tyre of a suitable sectional shape & thickness, preferably of a flat shape.
Around this india rubber tyre, I now place a thin ribbon of steel or metal of
a suitable shape and width. On this steel ribbon I fix a series of wood blocks,
enclosed more or less with steel or metal, if desired 1 place a thin layer of india
rubber between each of these blocks. These wood blocks are preferably wider
at the ends where fixed on steel ribbon, whereby they fit inside the steel or
metal tyre (or felloe) in a dovetail form, which prevents them being forced
out of place, the other ends of these wood blocks, come in contact with the road.
A suitable opening is made in the steel or metal tyre (or felloe) for the wood
blocks to pass & be fixed in their respective positions which is afterwards closed.
By this means the contact wear & tear of the road is taken up by the wood
blocks at the outer surface, which further serves in conjunction with the steel or
metal tyre (or felloe) as a protection to the india rubber while the elasticity &c.
of the latter is appropriated.

Improvements in Tyres for Wheels of Carriages or Vehicles of
every description.
I HENRY HOLLICK, of 39 Smithford Street, Coventry, in the County of
Warwick, Coach Builder, 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 the construction and arrangement of the tyres of
wheels for carriages or other vehicles whereby the elastic and noiseless advantages

page_text: of an india-rubber tyre may be secured, while the usual disadvantages viz. :-
excessive wear and tear.may be obviated in a better manner than before.
It consists primarily of the application of an extra or outer tyre or shield of
steel and wood arranged as hereinafter explained upon the underneath india-
rubber tyre.
In carrying out my invention I should proceed somewhat thus:-The steel or
iron felloes, or tyre of the wheel is suitably shaped at its outer circumference,
being more or less of a gutter form, its outer circumference or edges being
preferably narrower. Around this tyre (or felloes) is now placed an india-rubber
tyre of suitable sectional shape and thickness, preferably of a flat shape.
Around or in this india-rubber tyre I now place a thin ribbon of steel of a
suitable shape and width. Around and on this steel ribbon I now pin a series
of wood blocks enclosed more or less in steel or metal. If desired I place a
thin layer of india-rubber between each of these wood blocks. The outer end
of these wood blocks come in contact with the road. The other end is fixed on
the steel ribbon and is preferably a little wider whereby the steel or iron tyre
(or felloes) embrace this end in a dovetail form and prevents them coming off.
A suitable opening is made in the tyre or felloes and the wood blocks passed and
fixed in their respective positions and the opening is afterwards closed.
By this means the contact wear and tear of the road is taken up by the wood
surfaces of the outer tyre, which further serves with the steel or metal tyre (or
felloes) as a protection to the india-rubber while the elasticity &c. of the latter is
appropriated.
In order to more clearly explain this my invention, I have appended hereunto
an illustrative drawing upon which are figures and numbers of reference, similar
numbers referring throughout the several figures to the same thing or part.
Fig. 1, is a sectional view of this my invention, as seen on line A-B of Fig. 2.
Fig. 2, is a side elevation of a part of the tyre &c. of a wheel constructed
according to this my invention.
Fig. 3, is a plan view of the same.
Fig. 4, is a view in side elevation of a portion of the steel ribbon cover or
encasement as seen apart.
Fig. 5, is a sectional view of the wooden block and its steel encasement or cover,
as seen on line C-D Fig. 2.
· Fig. 6, is a sectional detail view of a portion of the iron or steel felloes shown in
its opened form to receive the blocks which is afterwards closed thereon.
Figs. 7, 89, and 10, are sectional views of modifications of details of this my
invention.
Referring to Figs. 1 to 6 inclusive:-10, is the ordinary wooden felly or rim of
a wheel. 11, is the iron or steel felly or tyre which in the case of a wooden wheel
is mounted upon the wooden felly 10, but in some cases the latter is dispensed with
and the said tyre is attached directly to the spokes. Within this tyre is now
deposited the india-rubber tyre or cushion 12, which may be varied in shape or
thickness.
13, is a block of wood whose grain is placed endwise, that is radial with the
wheel. Around the outer end of this block is a metal band or frame 14, which
is first heated and then shrunk on the said block, its interior shape being further
accommodated to ensure a firm hold upon the wood. The lower part of the
block is further widened at 15. 16, is a thin steel ribbon, formed into a gutter
like shape so as to encase the wooden blocks 13. In the side view of this steel
encasement as seen in Fig. 4 it will be noticed that at intervals along its two
sides gaps or openings 17, and 18, are made so that the said openings 17 accom-
modate the frame 14, while the openings 18, permit an easy bending of the
encasement to the contour of the wheel. The mid-portion 19, is carried upward
between the frame 14, and the wood block and then turned over rivetwise into the
wood as seen at 20, thereby securing the wood block, the frame and the encase-
ment firmly together. Furthermore, by reason of the outer part of the opening in

page_text: the frame 14, being enlarged or tapered a little, the tendency due to the wearing
pressure on the road, is to wedge out or rivet the wood blocks &c. within the
frame.
In some cases instead of making the encasement in one continuous piece from
block to block around the wheel I may make them separately to each block.
In some cases I may enlarge the bottom of the encasement 16, by forming
thereat beadings 21, 21, and afterwards inserting therein wires 22, 22, which may
run around the wheel in one or more pieces to suit the said encasements.
Also in Fig. 9, it will be seen that in some cases I may prefer to continue the
upright sides 23, 23, of the india-rubber upwards into the frame 14, the edges of
which are then protected by the turning over of the ends of the steel ribbon, as
seen at 19*. If desired the india-rubber cushion 12", may be enlarged and made
hollow to receive a pneumatic tube 28, as seen in Fig. 10, any ordinary suitable
provision being made for the requisite charging valve &c. If desired in some
cases I may provide that the successive blocks with their frames 14, shall engage
with each other by projections upon the one fitting into openings or recesses in the
other, such as the projections 24, fitting into the holes 25, as seen in Fig. 8.
In most cases the methods already described will be sufficient to secure the wood
blocks in the steel eucasement, but if necessary I may further secure them by
means of a nail or screw driven through the said steel into the wood or I may use
a taper pin 26, see Fig. 7, which is rivetted on the underside of the steel.
A portion of the iron or steel tyre 11, is left opened wide as seen at 27, Fig. 6,
when the blocks &c. may be passed in and slid around into position, when the
whole is complete this opened part is closed in as shown in dotted lines.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In tyres for wheels of carriages or other vehicles the combination with the
felly or rim 11, of such wheels, of the india-rubber tyre 12 or 12", and wooden
blocks 13, mounted and secured after the manner shown, all substantially as set
forth.
2. In tyres for wheels of carriages or other vehicles the combination with the
felly or rim 11, of such wheels and india-rubber tyre 12, of the blocks 13, having
the frames 14, and carried in the steel encasement 16, either separately or
continuously, substantially as set forth and shown.
3. The combination with the felly or rim 11, india-rubber tyre 12, and blocks 13,
of the encasement 16, having the beadings 21, 21, and the wires 22, 22, as set forth
and shown.
4. The combination with the felly or rim 11, india-rubber tyre 12, and blocks 13,
of the encasement 16, having the openings 17 & 18, as set forth and shown.
5. The combination with the felly or rim 11, india-rubber tyre 12, and blocks 13,
of the frames having the projections such as 24, at their one end fitting into and
engaging with openings such as 25, at their other ends, as set forth and shown.
6. The general combination and arrangement of the parts as herein described
and illustrated, constituting these my improvements in tyres for carriages or other
vehicles, substantially as set forth and shown.
Dated this 22nd day of February 1895.
