Improvements in Axles upon which Wheels are Fixed.
I THEOPHILUS CRISWICK of 31 Martin Street Morriston in the County of
Glamorgan Engineer do hereby declare the nature of my invention for IMPROVE-
MENTS IN AXLES UPON WHICH WHEELS ARE FIXED to be as follows:-
The object of this invention is to reduce the increased traction and wear of the
wheels consequent upon the two wheels being fixed upon the same axle in vehicles
travelling over any other than a straight road. The method by which this is done
is by making the axle in two or more parts, and connecting these parts together by
a coupling box or boxes also made in two or more parts. so screwed or otherwise
fastened together as to allow either part of the axle to turn independent of the
other part or parts within the box. The coupling box or boxes are also so made
as to allow of the adjustment required by the wearing of the axle, or of the box or
boxes themselves.

Improvements in Axles upon which Wheels are Fixed.
I, THEOPHILUS CRISWICK of 31 Martin Street Morriston in the County of
Glamorgan 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 object of this invention being to reduce the traction and wear of the wheels
consequent upon two wheels being fixed upon the same axle, in vehicles travelling
over any other than a straight road. This is accomplished by making the axle in
two or more parts and connecting these parts together by a coupling box or boxes
which box or boxes are made in two or more parts screwed or otherwise fastened
together and thus allowing either end of the axle to turn independent of the other.
The method of applying this to use is shewn in drawings herewith in which
Fig. 1 is a portion of axle in longitudinal section. Fig. 2 is a transverse section
in middle of the above, and Fig. 3 an end view from the outside. The axle is made
of about one half of its entire length, and towards that part where they join there
are projections or collars corresponding with those in the box so arranged that they
fit each other and when fastened together form an ordinary axle except that when
necessary one part can turn independent of the other within the box. Figs. 4, 5, 6
& 7 shew different forms of collars. If iron or other hard metal is used in contact
with the collars on axle the method shewn on Figs. 1, 4, 5 or 6 or some modification
of the shape would be used in the box, but for Babbits or other softer metal used
for running upon bearings the method shewn in Figs. 7 and 8 would be used proper
holes for pouring the metal being made in the box for so doing.
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 putting of more than one collar upon the ends of the pieces to form one
axle, and
(2) The making of the coupling box in parts so that the wear can be taken up,
and the parts again used as before.

to serve as a bearing in which either end of the axle can turn and also serve to
connect the parts together to form one axlea
