Improved Construction of Corve Wheels and Axles.
I, THOMAS ROWBOTHAM Commercial Traveller, residing at 87 Shaw Heath Stock-
port in the County of Chester do hereby declare the nature of this invention to be as
follows:
My invention relates to the construction of Wheels and Axles for Corves or other
similar wagons.
I make the wheels in such a form, as to obtain constant lubrication,
while the Corve is running, the working parts being protected from dirt, and all
waste of oil prevented, I also secure the wheels to the Axles by an improved method.
It must be understood that these are wheels that work loose on the axles; not fast
wheels.
To constantly lubricate the Wheel, and Axle, I fix an oil cup of special design,
containing oil chambers, in front of the wheel-the centre of the cup fitting loosely
on the end of the axle which stands the depth of the cup, through the boss of the
wheel and as the chambers in the oil cup are all made round it, and run into the hole
in the centre which receives the Axle end, it will be seen, that when the chambers are
supplied with oil, and revolve round the Axle end, they will continually drop the oil
on to the end of the axle, and the working of the wheel will carry the oil over the
whole bearing. When the wheel is standing still, the oil will rest in the bottom
chamber, and when the wheel revolves, bringing the bottom chamber to the top, the
oil will run on to the Axle, and all oil unused will run to the bottom Chamber again
for reuse.
I cast a shallow box on the wheel, in the form of a rim round the boss, and screwed
on the inside of the rim. The oil cup is screwed outside to fit into this rim, and the
outer edge I made octagonal, so as to be taken off easily for supplying with oil.

page_text: For the purpose of securing the wheel to the Axle I cast a small flange round the
boss of the wheel at the back edge. In the centre of the boss or flange I make a
recess to receive the collar of the axle. I then slip on a ring made to bear against
the back of the collar, and bolt to flange. The wheel is thus simply secured to
axle, and will work loosely on it while the working parts are protected from dirt.
The important points about the axles are, that the collar is made to fit into the boss
instead of outside, and of sufficient length to come through the Wheel, into the oil
cup, for constant lubrication.
Both wheels and axles may be made of steel or other suitable material, and in other
respects, of shapes that may be variously required.

I, THOMAS ROWBOTHAM, residing at 87 Shaw Heath Stockport in the County of
Chester, Commercial Traveller, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
My Invention relates to the construction of wheels and axles for Corves or other
similar waggons. I make the wheels in such a form as to obtain constant lubrica-
tion while the Corve is running; the working parts being protected from dirt and all
waste of oil prevented. I also secure the wheels to the axles by an improved
method.
It must be understood that these are wheels that work loose on the axles.
Figure 1 is an elevation of my improved wheels and axle, shewn in section, one
wheel being shewn with oil cap, loose ring, and thin packing detached, and the other
bolted together complete.
Figure 2 is an elevation of wheel casting with loose ring off, looking from inside.
Figure 3 is an elevation of wheel casting with oil-cap off looking from outside.
Figure 4 is a cross section of oil cap shewing oil chambers, also spiral spring and
button valve for admitting oil.
Figure 5 is the Button Valve and Spring detached.
Figure 6 is one of the Bolts passing through the loose ring and wheel, to secure
the wheel to the axle, also passing through and securing the Oil Cap to the Wheel
Casting. I may here observe that where preferred as in small wheels, the bolts may
be shortened and only used for securing the wheel to the axle. In that case the
outer edge of the Oil Cap would be made hexagon and a thread put on the Cap so as
to screw to the wheel.
A are the oil spaces or Chambers in Oil Cap.
B is the loose ring bolted to the inside of the wheel behind the axle Collar. C is
the axle. D is the Collar on the Axle.-It will be seen that when the Oil Cap is
supplied with Oil, say about half full, the Oil will pour on the axle when the oil
is carried to the top by the running of the wheel, and the oil that is not used will
flow into the other spaces for re-use, thus preventing all waste of oil. It will also
be seen that by bolting the loose ring B against the collar D that the bearing,
besides retaining the oil, is well protected from dirt.
I wish to be understood that in reference to the annexed drawings, that I do not
confine myself to precise details or relative proportions which may be altered without
interfering with the principles of the Invention.

page_text: 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 special construction of Wheel Casting herein described, particularly the
method of securing the wheel to the axle, by loose ring and recess in wheel to receive
the axle Collar-as applied to Corve Wheels or similar Waggons.
2. And particularly the special construction and use of Oil Cap herein described
and shewn in drawings, or its equivalent, by which, in conjunction with my
method of securing the wheels to the axle, I obtain (1) Constant lubrication.
(2) Prevent all waste of oil. (3) and fully protect the bearings from dirt.
