Vehicles.
I ALFRED DICKINSON of Tramway Depot Darlaston in the County of Stafford
Tramway Manager do hereby declare the nature of my said invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :—
This invention has for its object improvements in wheel journals and their parts
which are intended to lessen the friction and wear in the axles and journals of
vehicles thus reducing the initial power required in propelling or drawing them.
In order that my invention may be clearly understood and more easily carried
into practice I have appended hereunto three sheets of drawings illustrating one
form of my invention as applied to an Omnibus or ordinary road wheel but the
invention is equally applicable to Tram Cars and other vehicles.
Figure. 1. is a longitudinal sectional elevation through a broken off axle, broken
off wheel journal and spring.
Figure. 2. is an end elevation of the same parts which would of course be a part
side elevation of the said vehicles.
Figures 3 and 4 are side and front elevation of a wagon constructed with my
new journals axles and wheels.
In the sectional elevation Figure 1 both the wheel journal axle and spring are
shewn. D is the cast iron, steel or other centre of the wheel which are filled in
by the spokes E as mentioned in my previous Specification No. 16,316 A.D. 1886
or the wheel may in this respect be constructed in any known manner. The centre
of the wheel is fitted with the anti-friction bush G and separate anti-friction
collar L. The axle F is round and may be made from steel or other suitable
metal and is supplied with the collar P each end being drilled out or otherwise
made hollow as per S. in which any suitable lubricant may be placed and where it
is afterwards seald by the screw plug A. The lubricant passes through the
holes to the bush of the wheel and similar holes may pass to the antifriction
journal M which is held by the spring clip N directly to the spring C the
wrought iron, steel or other washer B keeping all the parts in position. The dust

page_text: is kept out of the journal by the India rubber or other flexible washer J which is
fastened to the metallic plate to give it stiffness as well as by the projecting parts h¹
and h² of the boss H. To avoid undue stiffness or rigidity I place inside each wheel
an India Rubber or other flexible spring collar K which allows for any side thrust and
in this manner avoiding any sudden or undue strain upon the axle as also the collar J
which acts similarly at the outsides of the hearings. It will thus be clearly understood
that the axle F is quite free to revolve in the spring bearings M and the wheel H is
also free to revolve upon the axle F and both these motions may continue together so
that the utmost freedom is obtained by this arrangement of parts which enables me to
use not only inside but also outside springs for Omnibuses and other vehicles without
increasing the guage of such vehicles. Sheet 3 of the drawings illustrates a wagon
mounted upon axles and wheels with outside springs as herein before set forth and
shewn in sheets 1 and 2 of the drawings and it will be there seen that the front wheels
will turn under the body without any difficulty.
my said invention
Having now particularly described and ascertained the nature of
and in what manner the same is to be performed I declare that what I claim is :-
First The improvements in wheel journals and their parts of an axle running
loose in end bearings M supported by springs with a wheel H mounted upon the axle
so as to run loose thereon and made dust proof substantially as herein set forth.
Second In the axle journals of wheels the elastic springs K and J to allow a little
latteral elasticity of the axle substantially as and for the purpose herein set forth.
