We FLORENCE MOORE wife of Captain Edward Crozier Sibbald Moore Royal
Engineers, of 5, Clarendon Place Citadel Road Plymouth, in the county of Devon
& EDWARD CROZIER SIBBALD MOORE, Capt Royal Engineers do hereby declare
the nature of the said invention for IMPROVEMENTS IN WHEELS AND AXLES FOR
RAILWAY AND TRAMWAY ROLLING STOCK to be as follows:-
>
The object of this invention is to do away with the strain of torsion on the
axles of railway plant by allowing the wheels on the same axle to revolve
independently of each other. It is proposed to effect this by making the axle in
two separate pieces. One of the wheels is attached to a solid round iron axle (K)
as shewn in the drawing and which fits inside the corresponding cylindrical (O.)
portion of the axle which is similary attached to the wheel. These two portions
of the axle are made as long as the space between the wheels will admit, and
bearings (P. Q) are provided as shewn in the drawing at the extremity of the solid
axle and also at its shoulder under the end of the cylinder.
Four brasses are shewn (L.) inside the mouth of the cylinder which can be
tightened up against the shoulder of the solid axle (K) by inclined surfaces on the
inside of a metal annulus (N.) the remainder of the inside surface of the annulus
being the same size throughout, so as to keep its centre and to move freely in a
longitudinal direction on the head of the cylindrical portion of the axle. Nuts
and bolts are shown for retaining the annulus on the head of the cylinder after the
introduction of brasses through slots left for the purpose, and for bringing the
incline surfaces to bear on the heads of the brasses as required.
The brass or metal socket to take the extremity of the solid axle is turned so as
to fit the base of the cylinder which is bored out to receive it, an inclined groove
is cut in its base to take a metal wedge, which passes through a slot in the cylinder
and serves to key the bearing and at the same time to tighten it as required, the
small end being rounded and a screw thread out on it to take nuts for drawing
it up..
This arrangement admits of the ordinary bearings of railway plant being used
and as only a differential motion would be possible between the solid axle and the
cylinder they would require but little attention and at the same time extreme
rigidity and strength would be secured.

Wo, FLORENCE MOORE, wife of Captain Edward Crozier Sibbald Moore R.E. and
EDWARD CROZIER SIBBALD MOORE Captain Royal Engineers of Salisbury House,
Salisbury Road, Dover in the county of Kent, do hereby declare the nature of our
invention for "IMPROVEMENTS IN WHEELS AND AXLES FOR RAILWAY AND TRAMWAY
ROLLING STOCK," and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :——
The object of this invention is, to do away with the strain of torsion, on the
axles of railway and tramway rolling stock, by allowing the wheels on the same
axle to revolve with different velocities.
The incidental advantages are, that the friction between the carriage and the
line, will be lessened, thus reducing the traction power required; and decreasing
the oscillation of the carriages. It will also effect a great saving, in wear and tear
of rolling stock and permanent way. It is proposed to effect these objects, by
making the axle in two separate pieces. The principal alteration is confined to
the portion of axle between the wheels. One of the wheels being attached to
a solid, round iron axle, (L) as shewn in the drawing, and which fits inside the
corresponding cylindrical portion (M), which is similarly attached to the other
wheel. These two portions of the axle, are made as long as the space, between the
wheels will admit, and bearings (X. Y.) are provided, as shewn in drawing at the
extremity of the solid axle, and also at its shoulder under the end of the cylinder.
Four brasses are shewn in drawing, inside the mouth of the cylinder, which can be
tightened up against the shoulder of the solid axle by wedge shaped projections on
the inside of a metal collar (Y) the remainder of the inside surface being the same
size throughout, so as to keep its centre, and to move freely in a longitudinal
direction, parallel to the axis, on the head of the cylindrical portion of the axle.
Nuts and bolts are shewn for retaining this collar, on the head of the cylinder,
after the introduction of brasses through slots left for the purpose, and for
tightening the bearings, by drawing the wedges against the heads of the brasses as
required.
5
The collar (Y) is made in two pieces, bolted together, for facilitating the
introduction &c of the brasses.
Two methods are proposed for constructing the bearings of inner end of solid
axle (X.) both are shewn in the drawing. The brass, or metal socket, to take the
extremity of the solid axle is turned so as to fit the base of the cylinder which is
bored out to receive it; an inclined groove is cut in its base, to take a metal
wedge, which passes through a slot in the cylinder, and serves to keep the bearing,
and at the same time to tighten it as required; the small end being rounded and a
screw thread cut in it to take nuts for drawing it up.
Similar bearings may also be used at the extremity of the solid axle to those at
shoulder, as shewn in "alternative section" in drawing; For the purpose of
lubricating these bearings, holes are bored from outer extremities of axle, along the
axis, so as to admit grease from grease box.

page_text: Each of the wheels may be cast with its corresponding half axle, or they may be
made separately and secured to the proposed axle in the ordinary manner.
The arrangement admits of the ordinary bearings of railway plant being used,
and as only a differential motion would be possible between the solid axle and the
cylinder, they would requiro but little attention, and at the same time, extreme
rigidity and strength would be secured.
•
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that
what we claim is
1. The method of making the portion of the axle between the wheels, in two
pieces, one working within the other, with bearings at either end, between the
cylindrical and solid portion of the axle, so that they bear on each other, but are
free to revolve at different velocities.
2. The method of forming the bearings in cylindrical axle of brass, gun metal,
or other metal, so that they can be tightened up by a collar having wedge shaped
projections on it for the purpose, and in the case of the extremity of solid axle by
means of a wedge passing through a slot in the cylinder.
3. The method of lubricating these bearings by an axial oil hole.
