Improvements in Wheels for Road Vehicles, Carriages,
and the like.
I, GEORGE THOMAS HYDE of 4 Little Moorfields, E.C., in the City of London,
Consulting Engineer, do hereby declare the nature of this invention to be as
follows:-
My Invention relates to an improved means for, and method of constructing wheels
for vehicles, carriages and the like, and has for its object, the reduction of the noise
which usually occurs when such wheels are at work upon the road, a more ready
method of construction, and a greater amount of elasticity than obtains with any of
the types of wheels in general use, and at the same time providing means for quickly
removing old, or worn spokes, and inserting new ones in their place, and generally
repairing the wheel without removing the tyre.
'
In carrying my Invention into effect I employ a wooden nave of special form
exteriorly, boxed in the usual way; around the outer surface of the nave at the part
where the spoke sockets occur in the wheels in general use, I provide a groove of
suitable depth and breadth, into which I force a ring of india rubber, or other
resilient substance or material, of the same width, and preferably about twice the
depth of the groove. Each spoke is tapered at the heel end, and forms a segment
of a circle, and when placed in position rests upon, and coincides with, the outer
surface of the india rubber ring before mentioned, which forms a seating for the
spokes, and these are held in position by two flat rings or washers, made of steel,
iron or other metal, sunk into and flush with the surface of the faces thereof; the
opposite end of each spoke is provided with a mortice in the usual way, upon
the shoulder of which I place a stout ring made of india rubber or other material of the
like, and attach the felloes to the spokes in the usual way. 1 provide two large flat
washers of india rubber, or other like substance and mount one on each side of the
nave close up to, and resting against, the faces of the spokes and the iron washers
before referred to. In order to retain and rigidly fix the spokes in position I provide
a metal clamp with a broad flange, shrunk or otherwise suitably fixed upon the back
of the nave and forced close up to, and pressing against the india rubber washer
before described and the side of the india rubber ring that is partially embedded in
the groove in the nave. Upon the opposite end or front portion of the nave I shrink
or otherwise fix a metal ring provided with a male screw thread; and a metal clamp.
similar to the one before described, and provided with a female screw thread is
screwed upon the metal ring last mentioned, until the flange of said clamp abuts:
against the face of the spokes in the same manner as the opposite clamp. The tyre:
may now be shrunk on and fixed in the usual manner. When it is necessary to
renew either of the spokes the last mentioned clamp is unscrewed and the old, or
broken spoke removed and a new one inserted, and the clamp screwed on as before.
The outer surface of the last mentioned clamp may be shaped to receive a spanner
and the front face provided with a fancy cap of any design or shape.
Dated this 30th June 1889.

Improvements in Wheels for Road Vehicles, Carriages,
and the like.
I, GEORGE. THOMAS HYDE, of 4 Little Moorfields, London E.C., Consulting
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 an improved means for and method of constructing wheels
for vehicles, carriages and the like, the object whereof is to reduce the noise which
usually occurs when such wheels are at work upon the road, a more ready method of
construction, and a greater amount of elasticity than obtains with any of the types
of wheels in general use, and at the same providing means for quickly removing old
or worn spokes, and inserting new ones in their place, and generally repairing the
wheel without removing the tire.
a
In order that my invention, and the manner of carrying out the same may be fully
and clearly understood I have appended the accompanying sheet of drawings, in
which, Fig. 1 is a side elevation of a portion of a wheel constructed according to my
invention, having part of the front clamp broken away to shew the internal arrange-
ment of the wheel, Fig. 2 is a cross sectional elevation of the same, Fig. 3 is part
of the wheel shewing the method adopted by me of attaching the ends of the spokes
to the felloes, and Fig. 4 is a sectional view of a felloe further illustrating Fig. 3.
Similar letters of reference indicate corresponding parts throughout the drawings.
In carrying out my invention I employ a wooden nave A formed exteriorly as
shewn for purposes to be hereinafter more fully explained, said nave is bored
longitudinally through the centre in the usual way, into which is pushed the box B
and retained therein by means of wedges driven between said box and the nave A in
the manner usually adapted in the boxing of carriage wheels generally. Upon the
outer surface of the nave A at the part where the spoke sockets occur in the wheels
in general use I, provide a groove or channel C, Fig. 2 of suitable depth and breadth,
into which I force a ring D made of india rubber or other resilient substance or
material, of the same width and preferably about twice the depth of the groove or
channel C, in such a manner that when in position the tension of elasticity of the said
ring D causes it to fit close to and tightly upon the nave A within the groove C,
said groove forming seating therefor prevents the possibility of its moving in a
lateral direction. Each of the spokes E are tapered at the heel end in such a
manner that when these are fitted together a continuous disc is formed, from which
the spokes radiate, the heel of each spoke resting upon the outer surface of the
ring D, annular grooves F are cut into the substance of the disc so formed, in
order to admit of the fitting of a metal ring G therein upon each side, to assist
in retaining the spokes in position upon the resilient ring D, said ring G when in
position being flush with the faces of the spokes. The opposite end of each spoke is
provided with a mortice H, Fig. 4 in the usual way, upon the shoulder of which 1
place a stout ring or collar I of india rubber or other resilient substance for the
purpose of giving further elasticity to the wheel, the mortice hole made in the felloe J
may be either bored right through or partly through said felloe, but must in any
case be of a depth corresponding to the length of the mortice H to allow of the
-depression of the ring or collar I. The felloes may now be attached to the spokes
in the usual manner. The rigidity of the spokes laterally are provided for in and by
the following manner.
I provide two large flat washers K and K' of india rubber
or other like substance and mount one on each side of the nave A close up to and
resting against the faces of the spokes E and the metallic ring G, said washers are
shewn in position at Fig. 2 but partly removed at Fig. 1 for the purpose of the
better illustration of the internal formation of my improved wheel. A metal clamp L
with a broad flange is fitted upon the back of the nave A and forced close up to and
pressing against the washer K¹ and the side of the ring D partly embedded in the

page_text: groove C, and is held firmly in position by being put on hot, and shrunk, or by pins,
screws or any other suitable means, upon the opposite end or front portion of the
nave A, I shrink, pin, screw or otherwise fix a metallic ring M, (the outer circum-
ference of the nave A having been reduced to receive the same) provided with a
male screw thread, a metal clamp N similar to the before-mentioned clamp L, and
provided with an internal or female screw thread, is screwed upon the ring M until
the flange of said clamp abuts against the washer K and the ring D in the same
manner as the clamp L upon the opposite end of the nave A. The clamp N may be
formed at its outer surface N¹ to receive a spanner, to assist the tightening and
removal thereof. The said clamp N is shewn in the front elevational view Fig. 1,
partly broken away for the purposes of illustrating the internal part of the wheel as
before mentioned. The tyre O may now be shrunk on and fixed in the usual manner,
and the front of the nave A may be furnished with a fancy band or cap P of any
design or pattern. The internal part of the box B does not differ in any way from
the boxes in general use, and the wheel according to
be fitted upon

may
A wheel constructed in the manner herein described and shewn according to my
invention possesses the advantage of being repaired to a great extent without removal
from the vehicle to which it is attached, and in many cases without removing the
load contained in said vehicle, and at the same time possessing greater elasticity, and
making less noise when in use than is the case with other wheels as hitherto made
and used.
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 :-

The improved wheel for road vehicles carriages and the like, substantially as herein
described and shewn by the drawings hereunto appended.
