on Rails and on Common Roads.
1, CHARLES PEACHEY HOLLISS, of 182, Irongate, Glasgow in the County of Lanark,
North Britain, Merchant, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to construct improved revolving axletrees for use on
vehicles running on common roads or on rails, which shall work with very little friction
on the bearings and cause the wheels attached to the said axletrees to revolve with
unequal velocities.
With this object the axletree is made in two parts each of which is provided with a
central recess to receive the half of a solid cylindrical dowel pin the longitudinal axis
of the dowel pin coinciding with the longitudinal axis of the axletree. This
arrange-
ment will allow the wheel at one end of the axletree to make a greater number of
revolutions than the wheel at the other end as they will revolve around the central
dowel pin independently of each other; hence the friction on the bearings will be
considerably less than it would be were the axletree rigid and the wheels traversing
unequal distances; e.g. running round a curve.
The two parts of the axletree are fitted together by means of a coupling box and the
whole is made stable by increasing the transverse section of the two parts of the
axletree for a few inches from the ends where they are jointed.
The coupling box is provided with an oil cup with a channel through which the
lubricant is led to the dowel pin.

I, CHARLES PEACHEY HOLLISS, of 182, Irongate, Glasgow, in the County of Lanark,
North Britain, Merchant, 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 object of this invention is to construct improved revolving axletrees for use on
vehicles running on common roads, or on rails which shall work with very little friction
on the bearings and cause the wheels attached to the said axletrees to revolve with
unequal velocities.
With this object the axletree is made in two parts each of which is provided with a
central recess to receive the half of a solid cylindrical dowel pin the longitudinal axis
of the dowel pin coinciding with the longitudinal axis of the axletree. This arrange-
ment will allow the wheel at one end of the axletree to make a greater number of
revolutions than the wheel at the other end as they will revolve around the central
dowel pin independently of each other, hence the friction on the bearings will be con-
siderably less than it would be were the axletree rigid and the wheels traversing
unequal distances; e.g. running round a curve.
The two parts of the axletree are fitted together by means of a coupling box, and
the whole is made stable by increasing the transverse section of the two parts of
the axletree for a few inches from the ends where they are jointed.
The coupling box is provided with an oil cup with a channel through which the
lubricant is led to the dowel pin, and other surfaces connected with the joint.
And in order that my invention may be more fully understood and carried into
practice, I will now proceed to describe the same with reference to the accompanying
drawings in which similar letters indicate corresponding parts in all the figures.
Fig. 1 is part of the section of an axletree for a road vehicle constructed according
to my invention.
Fig. 2 is an end view of the same looking in the direction of the arrow shown in
Fig. 1.
Figs. 3 and 4 are similar views shewing my invention as applied to an axle for use
on vehicles running on rails.
The axletree A revolves in an ordinary plummer block or blocks which are attached
to the springs or other convenient part of the vehicle in any well known manner.
The journals C of the axletree are provided with a flange or collar B on each side to
prevent the longitudinal travel of the axle. The wheels are rigidly fixed on the
axletree with three or more keys to keep them firmly in position. A cap D screws
over the ends of the keys and the axle to complete the fixing of the wheels.
The axletree is made in two parts and the ends F where they are jointed are
increased in transverse section for a few inches longitudinally.

page_text: A central longitudinal recess is bored or otherwise formed to receive the half of the
solid cylindrical dowel pin E, this dowel pin and the axletree being so constructed that
their axes are coincident as previously stated.
A coupling box G is placed over the pointed ends of the axletree and secured by
means of the screw nuts H at each end as shewn in Figs. 1 and 2 when used for a
road vehicle or by means of the flanges and bolts and nuts as shewn in Figs. 3 and 4
when used for a vehicle running on rails."
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 construction of revolving axletrees in two parts, fitted together by means of
the coupling box G and screw nuts H or flanges J. The ends of the said axletree
being centrally bored or otherwise recessed and fitted, closely but with freedom
to revolve, over a solid cylindrical dowel pin E substantially as and for the purpose
herein before set forth and illustrated in the drawings.
