COMPLETE SPECIFICATION.
Improvements in Means for Lubricating Vehicle-axles.
I WILLIAM WILMER CONNER, resident of New Street, Dover, Delaware,
U.S.A. Clergymau 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 has relation to means for lubricating vehicle-axles, and the object
is to provide a lubricating attachment of simple construction adapted to be
connected to the hub and formed with an aperture opening into the bore of the
hub and adapted to convey the lubricating substance to the surface of the
spindle..
My invention will be hereinafter fully described and specifically set forth in the
annexed claims.
and
In the accompanying drawings forming part of this specification:
Fig. 1 is a view showing the lubricator connected to the hub of a vehicle;
Fig. 2 is a central vertical section of the lubricator.
A designates the lubricating tube, the bore of which is preferably made
slightly tapering from top to bottom, as shown in the drawings. Midway between
the ends of the tube is an exterior annular shoulder or flange a, which sets down
tight on the surface of the holding nut b. The upper exterior end of the lubricating
tube is provided with screw threads c, with which engage the screw threads d in cut
with the interior of the depending annular flange e of the cap f, which serves to
cover and close the tube and exclude all foreign substances. The lower exterior
end of the lubricating tube is provided with screw threads g, which engage with the
screw threads in the interior of the holding nut 6 set in the hub, substantially as
shown.
In the interior of the lubricating tube is disposed a valve h, consisting of a stem i,
terminating in an enlargement i, at its lower end, which fits loosely in the bore of
the lubricating tube and serves to regulate the flow of the lubricating material to
the axle of the vehicle. The upper end of the valve h is provided with short
spring ears or arms k, the ends of which rest upon the top of the side walls of the
lubricating tube, as shown, the rise or descent of the valve being regulated by the
increase or decrease of the pressure upon the surface of the spring ears caused by
the adjustment of the cap on the tube."
To use my improvement, the oil or other lubricating medium is placed in the tube
and the cap screwed in place. The lubricating substance then descends and supplies
the lubrication essential to spindle.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
1. In combination with a vehicle hub, formed with an opening leading radially
through the hub, a holding nut, provided with interior screw threads seated in said
opening, a lubricating tube in the holding nut, baving a slightly tapering bore, and
screw threads on its lower end to engage in the holding nut, and an annular flange
to set down thereon, a valve formed with a stem terminating in an enlargement at

page_text: its lower end and having spring ears at its upper end, and a screw threaded cap to
close the tube and regulate the. position of the valve, substantially as and for the
purpose specified.
Dated this 30th day of July 1896.
