PROVISIONAL SPECIFICATION.
Improvements in Lubricating Appliances for the Bearings of Shafts.
We, PERCY BARRETT of 18 Northgate, Huddersfield, Engineer, and TOM
BROOK of Cleaveland Road, Lindley, Huddersfield, Engineer, both in the County
of York, do hereby declare the nature of this invention to be as follows:-
The object of our invention is to provide simple, inexpensive and reliable
means for constantly and automatically lubricating a shaft bearing by oil drawn
from and returned to a reservoir or tank formed within the pedestal. For this
purpose one end of a piece of cane, reed, rattan or other substance having a
porous cellular or like multitubular formation is placed in contact with the shaft
to be lubricated while the other or lower end is immersed in a reservoir of oil so
that the latter will by capillary attraction flow through the pores of the cane and
spread over the shaft as it revolves, the surplus oil flowing back into the reservoir.
In the accompanying illustrative drawings,
Fig. 1 is a side view, partly in section,
Fig. 2 is a plan, one half shewing the cover removed and
C
Fig. 3 is an end view partly in section of a pedestal or plummer block fitted
with a lubricating appliance according to this invention.
Figs. 4, 5 and 6 are corresponding views of a thrust bearing, the pieces of cane
in this case being inserted in the thrust collars in the pedestal.
Figs. 7, 8 and 9 are respectively a cross section, a longitudinal section, and a
horizontal section, shewing another form of pedestal in which the pressure on the
shaft is resisted by the upper step as in a locomotive or other form of axle bearing,
the lubricating canes being secured in a loose grid and held against the shaft in
any convenient manner such as by a light spiral spring.
Fig. 10 shews an ordinary needle lubricator wherein a piece of cane is substituted
for the needle. The same letters refer to corresponding parts throughout the
drawings.
A (Figs. 1, 2 and 3) is an ordinary form of pedestal provided with an upper
and a lower loose step B and B'. Below the latter cavities C are formed which
communicate by openings or channels D with annular channels C₁ formed at each
side of the bearing for catching the surplus or overflow lubricating oil. The dirt
in the oil deposits in the lower part of these annular channels and may be drawn
off by removing the set screw a whilst the clean oil flows into the central cavity C
and passes up through the cane plugs E E by capillary attraction, on to the shaft
again so that the same oil will act many times. The cane plugs E E are screwed
into screw threaded holes formed in the lower step B' as shewn, their lower ends
being tapered to allow a greater surface for attracting the oil. On the outside of
the pedestal brass rings F F are provided and fixed with screws for preventing
dust entering the bearing, the screw holes being slotted to allow for wear and
adjustment.
In the arrangement illustrated in Figs. 4, 5 and 6 which represent a thrust
bearing, the cane plugs E E are inserted in one or more of the loose collars as
seen in Fig. 4 and project into one or both of the cavities usually formed for the
circulation of water. In the arrangement illustrated in Figs. 7, 8 and 9 the lower
cap of the axle box is provided with a movable holder or grid G for the cane
pieces which are fixed therein and held in contact with the axle bearing by the
action of a suitable spring such as H on the said movable holder. The ends of
the canes E E project into the reservoir or cavity C in which the oil is contained.
The above described arrangements may obviously be modified to suit different
forms of hearing.

page_text: By the means described the same lubricating oil is used over and over again,
and any sediment formed collects at the bottom of the reservoir, below the point
where the canes terminate.
For lubricating ordinary journals the arrangement may be modified by inserting
a piece of cane in the neck of an ordinary bottle lubricator as shewn in Fig. 10,
and dispensing with the usual wooden plug, and wire spindle thus making a simpler
and cheaper lubricator.

Improvements in Lubricating Appliances for the Bearings of Shafts.
We, PERCY BARRETT of 18 Northgate, Huddersfield, Engineer, and TOм
BROOK of Cleaveland Road, Lindley, Huddersfield, Engineer, both in the County
of York, 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 our invention is to provide simple, inexpensive and reliable means
for constantly and automatically lubricating a shaft bearing by oil drawn from
and returned to a reservoir or tank formed within the pedestal. For this purpose
one end of a piece of cane, reed, rattan or other substance having a porous
cellular or like multitubular formation is placed in contact with the shaft to be
lubricated while the other or lower end is immersed in a reservoir of oil so that the
latter will by capillary attraction flow through the pores of the cane and spread
over the shaft as it revolves, the surplus oil flowing back into the reservoir.
Referring to the drawings filed with our Provisional Specification,
Fig. 1 is a side view, partly in section,
Fig. 2 is a plan, one half shewing the cover removed and
Fig. 3 is an end view partly in section of a pedestal or plummer block fitted with
a lubricating appliance according to this invention.
Figs. 4, 5 and 6 are corresponding views of a thrust bearing, the pieces of cane
in this case being inserted in the thrust collars in the pedestal.
Figs. 7, 8 and 9 are respectively a cross section, a longitudinal section, and a
horizontal section, shewing another form of pedestal in which the pressure on the
shaft is resisted by the upper step as in a locomotive or other form of axle bearing,
the lubricating canes being secured in a loose grid and held against the shaft in
any convenient manner such as by a light spiral spring.
Fig. 10 shews an ordinary needle lubricator wherein a piece of cane is substituted
for the needle. The same letters refer to corresponding parts throughout the
drawings.
A (Figs. 1, 2 and 3) is an ordinary form of pedestal provided with an upper and
a lower loose step B and B¹. Below the latter cavities C are formed which
communicate by openings or channels D with annular channels C¹ formed at each
side of the bearing for catching the surplus or overflow lubricating oil. The dirt
in the oil deposits in the lower part of these annular channels and may be drawu
off by removing the set screw a whilst the clean oil flows into the central cavity C
and passes up through the cane plugs E E by capillary attraction, on to the shaft
again so that the same oil will act many times. The cane plugs E E are screwed
into screw threaded holes formed in the lower step B₁ as shown, their lower ends
being tapered to allow a greater surface for attracting the oil. On the outside of
the pedestal brass rings F F are provided and fixed with screws for preventing

adjustment.
In the arrangement illustrated in Figs. 4, 5 and 6 which represent a thrust
bearing, the cane plugs E E are inserted in one or more of the loose collars as
seen in Fig. 4 and project into one or both of the cavities usually formed for the
circulation of water. In the arrangement illustrated in Figs. 7, 8 and 9 the lower
cap of the axle box is provided with a movable holder or grid G for the cane
pieces which are fixed therein and held in contact with the axle bearing by the
action of a suitable spring such as H on the said movable holder. The ends of
the canes E E project into the reservoir or cavity C in which the oil is contained.
The above described arrangements may obviously be modified to suit different
forms of bearing.
By the means described the same lubricating oil is used over and over again,
and any sediment formed collects at the bottom of the reservoir, below the point
where the canes terminate.
For lubricating ordinary journals the arrangement may be modified by inserting
a piece of cane in the neck of an ordinary bottle lubricator as shewn in Fig. 10,
and dispensing with the usual wooden plug, and wire spindle thus making a simpler
and cheaper lubricator.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. In lubricating appliances for the bearings of shafts, the application and use
of cane, reed or similar substance through which lubricating oil can pass to the
shaft to be lubricated by capillary attraction from an oil reservoir formed in the
pedestal substantially as described and illustrated.
2. The improvements in lubricating appliances for the bearings of shafts herein-
before described with reference respectively to and illustrated in Figs. 1, 2 and 3 ;
in Figs. 4, 5 and 6; in Figs. 7, 8 and 9; and in Fig. 10 of the accompanying
drawings.
