PROVISIONAL SPECIFICATION.
Improved Means for Supplying Lubricant to Corve Wheels.
I, THOMAS ROWBOTHAM Commercial Traveller residing at 87 Shaw Heath
Stockport in the County of Chester do hereby declare the nature of this invention
to be as follows:-
In order to give each wheel a certain supply of oil quickly, I fix a spiral spring
with a button on the end, into the centre of the adjustable plug of my patent
wheel No. 6232/90-one end of the spiral spring bearing against the axle end, and
the button end pressing against the inside of the plug like the seating of a valve-
to keep in the oil when closed, and admit it when open.
I cut grooves or slots crosswise in the inside of the plug, so that when the button
is pressed in, the oil will flow down the slots into the wheel even when the axle end
is close against the plug.
To open the valve, and inject the oil quickly into the wheel, I use a syringe with
a nozzle of special design, that is instead of having a hole straight through the
centre to squirt the oil forwards-I leave the end blank, and insert holes in the
sides of the nozzle, so as to squirt sideways through the slots in plug.
I place a rubber or leather ring round the top of the nozzle, so that when
the blank end of the nozzle is pressed against the button to open the valve-this
ring will come against the outer edge of the oil hole, and prevent any back flow.
It will thus be seen that the whole contents of the syringe may be quickly forced
into the hollow boss of the wheel. And as I make the syringe to hold just sufficient
to supply one wheel, it will be seen that by means of this special design of syringe
along with the valve arrangements in the adjustable plug, I secure the .means of
giving a quick & certain supply of oil to each wheel.

I THOMAS ROWBOTHAM Manufacturer & Agent residing at 99 Shaw Heath
Stockport in the County of Chester 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 :-
My invention is for supplying a measured quantity of oil quickly to my patent
wheels No. 6232/90. For this purpose I make a special form of oil syringe to work
in conjunction with an arrangement of spring valve fixed in the centre of the
adjustable plug of my wheel, instead of the small screw plug which had to be taken
out each time for oiling.
The annexed drawings will shew the arrangement.
Fig. 1 is an elevation of one of my patent wheels named above fitted with small
screw plug for oiling.
Fig. 2 ditto, but fitted with spring valve for oiling in place of plug.
Fig. 3 is a face view of the adjustable plug. A are the grooves for admitting
oil, when the axle is against the face of the plug.
Fig. 4 is my special syringe made to hold enough oil to supply one wheel.
It will be seen that the nozzle of the syringe is so formed that when pressed
against the spring until the rubber or leather ring B comes against the face of the
wheel the valve will be open, and the whole contents of the syringe may be injected
[Price 6d1

page_text: into the hollow boss of the wheel, the ring B pressing against the face of the plug
will prevent any back flow.
I do not claim that the use of a syringe for oiling is new, or the fixing of a
spring valve in a hollow bossed wheel.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1st. The special form of syringe shewn in Fig. 4 particularly the form of nozzle,
with the squirt holes C and the ring B or their equivalent.
2nd. And particularly the special arrangement of spring valve in the centre of
the wheel with the grooves A, by which in conjunction with my special syringe a
measured supply of oil may be quickly supplied to my wheels herein named.
Dated this 4th day of August 1891.
