PROVISIONAL SPECIFICATION.
An Improved Axle Lubricator.
We, WILLIAM JACKSON MILLER of Colorado, Mitchell County, Texas,
United States of America, Mechanic, and MOSES HALL of the same place,
Ranchman, do hereby declare the nature of this invention to be as follows :-
The lubricator of this invention consists of a bush fitted into the wheel hub and
having at about the middle of its length a recess round it which serves as an oil
channel round the axle or round the axle spindle sleeve fixed thereon. The end of
the axle spindle is screw threaded, the inner portion of the thread serving for
securing the axle sleeve and the outer end for the reception of a cap or socket nut
provided at its inner edge with notches for feeding the lubricant through to the
axle or sleeve of the same. The nut is provided with a collar and when screwed
up forces the lubricant into the axle bush and by its collar taking against the outer
end of the bush forms a closed lubricant chamber.

COMPLETE DIEUITICATION.
An Improved Axle Lubricator.
We, WILLIAM JACKSON MILLER, of Colorado, Mitchell County, Texas,
United States of America, Mechanic, and MOSES HALL of the same place,
Ranchman, 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 :-
In the drawing Fig. 1 is a longitudinal section of a wheel hub with an axle
carried therein and embodying the improvements of this invention. Fig. 2 a similar
view of the outer end of the axle and wheel hub the lubricating nut at the
end being partly unscrewed for the reception of a lubricant. Fig. 3 an end view of
the same. Fig. 4 is an inner end view of the lubricating nut.
1 is the square part of the axle, 2 the taper spindle having at the inner end an
enlargement 3. 4 the axle skein which at its outer end is provided with an internal
screw thread for screwing tightly on to the taper spindle 2 the enlargement 5 of the
skein fitting closely against the enlargement 3 of the spindle. 6 the wheel hub.
7 a bush driven tightly into the hub the ribs 8 preventing the bush from turning.
9 an oil channel or oil chamber round the inside of the bush. The outer end of the
latter extends some distance beyond the end of the axle and its skein 4, and is
internally screw threaded for the reception of the lubricating screw cap 10 having
a shoulder 11 which takes against the end of the hub bush 7 and having also an
aperture 12. 13 is an outer metal covering of the wheel hub on each side of the
spokes 14 and having flanges 15, the two parts of the covering being secured to
the spokes by rivets 16. The inner end of said covering is internally screw
threaded for the reception of the flanged collar 17 which when in position bears
on the end of the enlargement 5 of the axle skein and thus holds the wheel in
position upon the axle as shewn in Fig. 1.

page_text: The cap 10 carries the oil supply for the lubrication of the axle and is unscrewed,
as shewn in Fig. 2 when it is to be charged with oil, the aperture 12 for the purpose
being then beyond the outer end of the bush 7. After charging and upon screwing
back the cap the aperture 12 is closed and the oil forced between the axle skein 4
and the hub bush 7 into the oil channel 9. In this way there is no waste of oil,
all the parts fitting closely together and the oil working in between the axle skein
and the hub bush slowly. The cap 10 after being charged with oil will not require
a fresh supply for a long time and can be readily refilled.
The construction and arrangement of some of the parts may be modified, for
example, the hub bush 7 may be extended farther over the end of the axle and a
hole made in the upper part thereof near the end instead of the provision of an
aperture or notch in the cap 10 which could then be filled with oil when partly
unscrewed, the hole being then closed by screwing in the cap.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In combination with a wheel hub fitted with a bush, a cap screwing into the
end of said bush and covering the end of the axle, said cap being provided
with an aperture for the reception of oil after partial unscrewing and when screwed
in closing such aperture and forcing the oil between the axle or axle skein and the
hub, substantially as described and shewn.
2. In combination, a wheel hub fitted with a bush provided with an internal oil
chamber or chanuel, a skein on the axle fitting into said bush, a flanged collar
screwing into the inner end of the hub and bearing against an enlargement of the
axle skein and a lubricant cap provided with an aperture or notch for filling in the
lubricant without removing the wheel, substantially as described and shewn.
