Improvements in Wheels for Vehicles.
I, WILLIAM HENRY MOORE, of 143 Kingsland Road, in the County of London;
Engineer, do hereby declare the nature of this invention to be as follows:-
The invention has for its object improvements in wheels for vehicles with a view to
reduce the amount of vibration communicated from the wheels to the vehicle.
For this purpose I form a larger hole in the nave of the wheel than that generally
employed, so as to leave an annular space between the axle box and the interior
of the nave.
Around the axle box I fit a sleeve having a right and left hand screw
thread around its exterior. On the said screw threads, near the centre, I place nuts
and against such nuts and occupying the annular space between the sleeve and the
nave, I place rings or tubes of India-rubber. The nuts are not so large as to touch
the interior of the nave, thereby avoiding any rigid contact between the sleeve and the
nave. The sleeve is provided with means whereby it can be rotated so as to move the
nuts simultaneously away from or towards each other, and rings or flanges are secured
to the outer faces of the nave to hold the India-rubber against the pressure of the
nuts. A circumferential groove is formed in the interior of the sleeve, and a pin or
stud projecting from the axle box enters such groove to prevent endway notion of
the sleeve and suitable means are provided to prevent the wheel from creeping
around the axle box. The axle box is formed as heretofore with a fixed flange, against
which the wheel nave is placed, and it has a screwed plate on its outer end to secure
the wheel in position.
By the construction herein described the wheel has no direct bearing on the axle
box but a substance of India-rubber is interposed between them and the India-rubber
can have any desired amount of pressure put thereon by means of the sleeve and
nuts.
I, WILLIAM HENRY MOORE, of 143 Kingsland Road, in the County of London,
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.
The invention has for its object improvements in wheels for vehicles with a view to
reduce the amount of vibration communicated from the wheels to the vehicle. I
will describe my invention in connection with the accompanying drawings in which

improvements Fig: 1 showing the parts previous to the India rubber tubes being
screwed up to fix the wheel in position on the axle box and Fig: 2 showing such
parts after having been screwed up-Fig: 3 is a cross section of half of the nave
and parts fitted therein. Fig: 4 is an exterior view of my improved fittings, Figures 5
and 6 are cross sections of Fig: 4 drawn respectively on the lines 5. 5 and 6. 6 and
Fig: 7 is an exterior view of parts.
In carrying my invention into effect I form a larger hole in the nave a of the
wheel than that generally employed so as to leave an annular space between the
axle box b and the interior of the nave a. Around the axle box b I fit a sleeve c having
a right and left hand screw thread around its exterior. On the said screw threads at
or near the centre I place nuts d. d¹ and against such nuts and occupying the annular
space between the sleeve c and the nave a I place rings or tubes e. e¹ of India rubber
and I also place a rubber tube e² around the inner end of the axle box b.
The nuts d. d are not so large as to touch the interior of the nave a thereby
The sleeve cis
avoiding any rigid contact between the sleeve c and the nave a.
provided with means, such as notches c' in its end, by which, aided by a suitable
key, it can be rotated so as to move the nuts d. d' simultaneously away from or
towards each other, and a ring or flange a¹ is secured to the outer face of the nave a
to hold the India rubber rings e, el, against the pressure of the nuts d, d¹. In order
to prevent the India rubber ring e' from being squeezed over the outer end of the
sleeve c I interpose between the outer end of the ring e¹ and the ring or flange a¹, a
metal ring which fits closely around the outer surface of the sleeve c and thereby
keeps its notched end free for the action of the key thereon.
A circumferential groove 61 may be formed on the exterior of the axle box and a
pin or stud c✶ projecting from the sleeve c may be provided to enter such groove to
prevent endway motion of the sleeve on the axle box but such may be dispensed
with if desired.
In order to prevent the wheel from creeping around the axle box and at the same
time retain the nuts d. d¹ from rotation with the sleeve c and the rubber
ringe and metal ring f from moving in relation to each other when the sleeve is
rotated I form grooves e³, d² and f¹ respectively in opposite sides of the India rubber
rings e. e', nuts d. d and ring f and I fix within the wheel nave, on opposite sides
thereof, two tongues a² fitting into such grooves e³ d² and f¹.
The axle box b is formed as heretofore at its inner end with a fixed flange 6², which
for convenience is screwed thereon, and against which the wheel nave a is placed;
this flange b2 is provided with large holes 63 through which screws 64 are passed to
fix it to the wheel nave without causing rigid radial contact between the wheel nave
and the axle box.
The axle box is also provided with a screwed plate 66 on its outer end to
secure the wheel in position and a cap g is screwed into the outer end of the
axle box as usual.
By the construction herein described the wheel has no direct bearing on the
axle box but a substance of India rubber is interposed between them and the India
rubber can have any desired amount of pressure put thereon by means of the
sleeve c and nuts d. d.
I would here remark that in Figures 1 and 4 the plate 65 and cap g are shown in
position but these would naturally not be in place until the rubber rings are screwed
up tight.
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 improvements in wheels for vehicles, substantially as herein set forth.
2. In wheels for vehicles the combination with the axle box of a right and left hand
threaded screw sleeve fitting the exterior thereof, two nuts capable of travelling on

page_text: against the nuts, a shoulder on the axle box against which one of such rubber
rings is forced by its nut, a ring plate on the outer face of the nave against which
the other rubber ring is forced by its nut, longitudinal grooves in the said rubber
rings and nuts, longitudinal tongues fixed within the nave and fitting the above
mentioned grooves, means for retaining the axle box within the nave, and means for
rotating the screw sleeve, substantially as herein shown and described and for
the purpose stated.
3. In wheels for vehicles the improved arrangement and combination of parts,
substantially as herein set forth and for the purpose stated.
