Improvements relating to the Lubrication of Road Vehicle Axles
and the like.
I, ELIZA DALTON of Big Hill via Marulan County of Argyle in the Colony of
New South Wales Gentlewoman 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 my invention is to do away with the necessity of taking the caps
and wheels off carts carriages &c. when they require oiling.
My invention consists of an apparatus comprising a short tube with a head on
one end larger than the tube itself. On the tube side of the head I purpose making
a small hole to communicate with inside of tube, on each side of tube I also
purpose having two ribs to act as guides; I then would make a hole in the end of
an axle cap, axle or the like and on each side of the hole I would make a slot, after
which I would then insert the tube in the hole described, and ribs on the side of
tube would then fit into the slots in hole in axle cap the head on end of tube being
larger than the hole itself will prevent tube going too far through cap; on the
tube inside of cap intend to place a spiral spring and to keep the spring on tubo
a washer will be held in place by putting a pin through end of tube on the inside
of the cap, in the head of the tube on the outside there will be a small recess to
admit of a key with stops to prevent key turning all round, the key is to be used
for drawing the tube outwards when it is intended to fill with oil the axle cap by a
slight turn with the key, when tube is brought forward the ribs will clear slots in
hole of cap and will then remain with tube open, the hole in top of tube is then
exposed and can be filled with oil which is then carried through tube into cap,
when full the key is then used to turn tube back until ribs are opposite the slots,
the spiral spring then draws tube back into the cap the head fitting tight on face
of cap which then prevents the oil from escaping when cap revolves; a small
leather or other kind of washer can be placed behind head of tube if required
should oil attempt to escape.
In the case of nut ended axles, I would bore a hole into the end of axles
sufficient for the purpose and then I would make another through the arm jfrom
recess to communicate with hole in centre, but in order that my invention may be
better understood reference is made to the attached drawing.
Fig. 1 is a plan showing axle cap.
Fig. 2 is a section showing side of axle cap with lubricator drawn out held open
by lugs to receive the oil.
Fig. 3 is a section of cap showing lubricator in cap closed.
Fig. is a section of a common nut ended axle showing lubricator through cap
and into arm of axle closed.
Fig. 5 is a section of common axle nut with lubricator open.
Fig. 6 is a plan of common axle nut with the before said parts attached similar
to Fig. 1.
A. on Fig. 1 is axle cap.
B. is the hole in cap to receive the tube.
C. shows the slots to receive the lugs on tube.
J. is key slot to admit key K, (Fig. 2).
D. on Fig. 2 is the tube which carries oil to axle, drawn outwards.
E. is the hole on the top of tube where the oil is run into cap.
F. are the lugs for keeping tube open.
L. is the outside head of tube with key slot J in end.

page_text: G. is the spiral spring for drawing back the tube D after charging with oil.
H. is the washer on end of tube D.
1. is the pin to keep washer H in place on tube.
Fig. 4. shows a common nut axle. P is the hole down centre. O is the hole
through axle to communicate with hole.
I would not bind myself to axle caps and axles only as shown on annexed
drawings but I would attach the parts claimed to any similar kind of apparatus
they would suit.
I purpose making these lubricators out of brass and springs of steel, but do
not confine myself to that material nor to sizes shown but will make them any
size required and out of any material that will suit the purpose, so long as the
features of my invention are retained.
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
claim is :-
1st. In a lubricating axle cap, axle and the like the combination of the hole 13
having slots C with cap A. substantially as herein before described and as illustrated
in drawing on Fig. 1.
2nd. In a lubricating axle cap, axle and the like the combination of the tube D,
hole E, lugs F, head of tube L, spirul spring G, washer H, pin 1, key slot J, and
key K, with cap A, substantially as herein before described and as illustrated in
drawing on Figs. 1 and 2.
3rd. In a lubricating axle cap, axle and the like the combination of the hole P
and hole O, with all the herein before mentioned parts in Figs. 1 and 2, with axle
cap and axle substantially as herein before described and as illustrated in drawing
on Fig. 4.
