PROVISIONAL SPECIFICATION.
An Improved Lubricator for Lubricating the Wheels of Vehicles and
other like Purposes.
1, JAMES YATE JOHNSON of 47 Lincolns Inn Fields in the County of Middlesex
Gentleman do hereby declare the nature of this invention which has been com-
municated to me from abroad by La Société Million-Guiet et Cie of Paris in the
Republic of France to be as follows:-
This invention relates to an improved lubricator consisting of chambers arranged
to supply an axle journal or the like with grease or other lubricant in such a
manner as to secure an effectual and economical lubrication of long duration as
hereinafter explained.
This lubricator can be employed with ordinary axle or other grease or oil and
consists of one or preferably two or more hollow ears or projections formed on the
axle or journal box and forming receptacles or chambers for holding the lubricant.
These receptacles or chambers are closed at one end by a screwed plug or stopper
forming a point of support for a spring exerting pressure on a piston acting on
the lubricant and causing it to flow from the chamber through a channel or passage
leading to suitable helical or other oil grooves formed in the bearing surface.

other like Purposes.
I, JAMES YATE JOHNSON of 47 Lincolns Inn Fields in the County of Middlesex,
Gentleman do hereby declare the nature of this invention (which has been com-
municated to me from abroad by La Société Million, Guiet et Cie of Paris in the
Republic of France) and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
This Invention relates to an improved lubricator consisting of a metal grease box so
arranged as to secure an effectual and economical lubrication of long duration as
hereinafter explained.
And in order that my said Invention may be fully understood I shall now proceed
more particularly to describe the same and for that purpose shall refer to the several
figures on the annexed sheet of drawings the same letters of reference indicating
corresponding parts in all the figures.
Figure 1 of the accompanying drawings represents a longitudinal section, taken
along the axis of the axle or journal, of a lubricator according to this invention
applied to the axle of a vehicle and Figure 2 represents an end elevation of the
journal box.
The box lubricator in this example is constructed in the form of lugs A formed on
the journal box or bush and in which are receptacles or chambers B for holding the
oil or lubricant. These receptacles or chambers B are closed at one end by a screwed
plug or stopper C forming a point of support or bearing for a spring and exerting
pressure on a small piston pacting on the lubricant in the chamber B and causing
it to flow from the chamber through a channel or passage D leading to helical or
other suitable oil grooves E formed in the bearing surface. It is evident that any
suitable number of these grooves may be employed and that any number of oil
chambers B or lugs A may be provided on one bush or bearing.
The action of this lubricator is readily understood without further description by
referring to the accompanying drawings.
This lubricator can be employed with ordinary axle grease or other grease or
lubricant and presents the following advantages namely―
1. Overheating of the axles or journals and the consequent binding action are
completely obviated.
2. The wear and tear of the axle journals washers nuts and boxes is reduced to
a minumum.
3. The oil or grease reservoir heretofore employed is dispensed with and the false
bearing or bad distribution of the pressure which sometimes causes the fracture of
the axles is obviated. The box bearing on the axle close to the collar or washer
the strain on the axle is diminished.
4. When applied to carriage axles this lubricator has the additional advantage
that the grease chambers are sunk into the nave without projecting from its surface
and without weakening it. The neat appearance of the wheel is thus preserved.

page_text: 5. The leakage and waste of lubricant which occurs in ordinary oil or grease
boxes is prevented.
6. Owing to defects in casting there is often a leakage of oil through the bush into
the interior of the nave which spoils the wheel by percolating to the spokes, this
inconvenience is obviated by the use of the improved box herein described.
7. The lubricating can be performed without taking off the wheels, a point
of great importance in the case of heavy vehicles with large and ponderous wheels.
8. This lubricator is applicable to all kinds of axles employing oil or grease it only
being necessary to modify the proportions according to the different constructions.
9. No special workmanship or tools are required for fitting the lubricator box into
the wheel beyond what is at the command of an ordinary wheel-wright.
10. These lubricators do not entail any modification of the axles, and in particular
when combined with patent axles lubricated with oil they constitute a most perfect
system of lubricators.
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. Lubricators for wheels of vehicles and the like in which the lubricant is contained
in hollow lugs or projections (A) provided with chambers (B) for the reception of the
lubricant the said chambers being closed by screw stoppers (C) forming supports for
springs () pressing against pistons (p) tending to expel the lubricant through
passages (D) into oil grooves (E) in the surface of the bush or bearing substantially
as herein before described and illustrated in the accompanying drawings.
2. The improved construction combination and arrangement of parts constituting
the improved lubricator for lubricating the wheels of vehicles and other like purposes
substantially as hereinbefore described with reference to the accompanying drawings.
Dated this 6th day of December 1888.
