PROVISIONAL SPECIFICATION.
Improved Means for Lubricating Shafts Packed in Stuffing-box
Bearings.
We, JOSEPH ARMYTAGE WADE, of Hornsea, in the East Riding of the County
of York, Timber Merchant, and John CHERRY, of Hornsea, in the East Riding
of the County of York, Mechanical Engineer, do hereby declare the nature of
this invention to be as follows:-
This invention relates to improved means for lubricating the shafts of engines,
pumps
and other machines having their shafts packed and carried in stuffing-box
bearings.
In applying our invention to the bearing of a rotary pump spindle, by way of
example, we form around the stuffing-box an annular chamber, which is fed with
oil, or other lubricant from an oil-cup of any suitable type. Between the
annular oil-chamber and the exterior of the packing and of the bush, small holes
are drilled; these being disposed radially and at suitable intervals in a longi-
tudinal or other direction so as to convey the lubricant to the gland, to the
packing and to the brush independently corresponding holes being formed in
the latter in order to conduct the lubricant to the surface of the shaft. The
bearing is by preference constructed in halves in order to facilitate the drilling of
the oil-ducts in the inner wall of the annular oil-chamber.

COMPLETE SPECIFICATION.
Improved Means for Lubricating Shafts Packed in Stuffing-box
Bearings.
We, JOSEPH ARMYTAGE WADE, of Hornsca, in the East Riding of the County
of York, Timber Merchant, and JOHN CHERRY, of Hornsea, aforesaid, Mechanical
Engineer, 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 :-
•
This invention relates to improved means for lubricating the shafts of engines,
pumps and other machines having their shafts packed and carried in stuffing-box
bearings.
In the accompanying drawings, we have shewn, by way of example, a rotary
pump embodying our invention.
Fig. 1 is a front view, partly in elevation and partly in section ;
Fig. 2 being a corresponding side view.
A is the casing of the pump, B the pump-spindle, B₁ the rigger through which
the pump
is driven, C the inlet and D the outlet. EE are the stuffing-boxes, and
FF the glands.
We form around each stuffing-box E an annular chamber G, which is fed
with oil, or other lubricant, from an oil-cup of any suitable type, such as H.
Between the annular oil-chamber G and the exterior of the packing J and of the
bush K, small holes g are formed by drilling or otherwise; these being disposed
radially and at suitable intervals in a longitudinal or other direction, so as to
convey the lubricant to the gland, to the packing and to the bush independently;

to the surface of the shaft B.
If the oil-ducts 9 be drilled in the inner wall of the annular oil-chamber G,
the bearing is by preference constructed in halves in order to facilitate the
operation of drilling.
Our improved means for lubricating may be applied to the bearings of propeller-
shafts, crank-shafts, shafting, axles and spindles in a similar manner.
In the example given in the accompanying drawings, the bearings are horizontal
and the annular oil-chambers G do not completely encircle the shaft, because there
is no necessity for their doing so, as, even if they did, the oil in their lower parts
would only remain stagnant. If, however, the bearings be vertical or inclined, the
annular oil-chambers should completely encircle the shaft.
Having now particularly described and ascertained the nature of this invention,
and in what manner the same is to be performed, we claim :-
The improved means for lubricating shaft-bearings arranged substantially as
herein described and comprising an oil-chamber, such as G, whence oil-ducts g lead
to the packing and bush, to the packing and gland, or to the packing, bush, and
gland respectively.
