WILLIAM PHILLIPS THOMPSON. Fel. Inst PA of the Liverpool and London
Agency for Foreign Patent Solicitors, 6 Lord Street Liverpool in the county of
Lancaster Civil Engineer "IMPROVEMENTS IN APPARATUS FOR OILING CRANK
PINS IN PART APPLICABLE TO OTHER PARTS OF MACHINERY a communication
from Charles H Parshall a person resident at Detroit, Michigan, United States [of]
America
This invention consists in the combinations of devices and appliances hereinafter
specified.
In the drawings
Fig 1 is a side elevation of a device embodying the invention and showing parts
in section
Fig. 2. is a variation
It is the object of this invention to provide a crank pin oiler which shall take
its oil from a stationary reservoir and feed it thence to the crank pin through a
transparent chamber, whereby the rate of feed of the oil can be witnessed. Also
in providing a crank pin oiler with a stationary reservoir and a flexible metallic
connection between the reservoir and the crank pin Also in a crank pin oiler a
stationary reservoir, a flexible metallic connection with a crank pin and a
transparent water chamber located between the reservoir and the crauk pin through
which the drops of oil rise on their way to the crank pin

page_text: In carrying out the invention A represents any suitable reservoir for the oil
B is a crank pin to be oiled C is any stationary support D is a flexible metallio
connection between the crank pin and the reservoir.
This flexible connection may be in the nature of a telescopic arrangement of
tubes D and D' one operating within the other, as the crank operates as shown in
the drawings, or as shown in the variation the tube may be made in the nature of
an elbow joint which straightens out as the crank recedes and doubles up as it
advances
E is a water chamber made of glass or other transparent medium. It is
so located between the reservoir and the crank pin that the oil as it leaves
the reservoir rises through the water in visible drops thus indicating the rate of
feed.
Instead of being a water chamber however, this might be a transparent air
chamber, and the oil be caused to drop down through it, it only being essential that
the chamber should be transparent.
The neck & which connects the transparent chamber with the flexible metallic
connection may be of any desired length
It may as shown in the drawings be such as to locate the reservoir close to the
crank, or the reservoir may be located in any other place and the oil be carried
thence to the transparent chamber E and thence to the flexible connection and so
to the crank pin.
If the device is of the telescopic form shown in the drawings it will operate
more or less in the nature of a pump and in that ovent there should be a valve F
located at the top of the transparent chamber
So also it is preferable generally to employ a valve G for regulating the flow
of oil.
A lubricator of this character will be found to be very effective in its operation
while the supply of oil is kept uniform and the reservoir is at all times accessible
for refilling cleansing et-cetera
It is apparent that at the top of the flexible tubes where they connect with
the water chamber, or with the pipe leading therefrom there is provided a
flexible joint so as to conform to the movement of the crank, and a similar flexible
connection is made at the point where it is united to the crank pin.

WILLIAM PHILLIPS THOMPSON. Fel. Inst. P.A. of the Liverpool and London
Agency for Foreign Patent Solicitors, 6 Lord Street, Liverpool in the county of
Lancaster, Civil Engineer "IMPROVEMENTS IN APPARATUS FOR OILING CRANK-
PINS, IN PART APPLICABLE TO OTHER PARTS OF MACHINERY." A communication
from Charles H. Parshall, a person resident at Detroit, Michigan, United States of
America.
This invention consists in the combination of devices and appliances hereinafter
specified and more particularly pointed out in the claims. In the drawings Fig 1.
is a side elevation of a device embodying the invention, and showing parts in
section. Fig. 2 is a variation.
It is the object of this invention to provide a crank pin oiler which shall take
its oil from a stationary reservoir and feed it thence to the crank pin through a
transparent chainber, whereby the rate of feed of the oil can be witnessed. Also
in providing a crank pin oiler with a stationary resevoir and a flexible metallic
connection between the reservoir and the crank pin. Also in a crank pin oiler, &
stationary reservoir, a flexible metallic connection with a crank pin, and a
transparent water chamber located between the reservoir and the crank pin, through
which the drops of oil rise on their way to the crank pin.
In carrying out the invention A, represents any suitable reservoir for the oil.
B is a crank pin to be oiled. C is any stationary support. D is a flexible metallic
connection between the crank pin and the reservoir.
This flexible connection may be in the nature of a telescopic arrangement of
tubes D' and D2, one operating within the other, as the crank operates, as shown
in the drawings, or as shown in the variation the tube may be made in the nature
of an elbow joint which straightens out as the crank recedes and doubles up as it
advances.
E is a water chamber made of glass or other transparent medium.
It is so located between the reservoir and the crank pin, that the oil as it
leaves the reservoir rises through the water in visible drops, thus indicating the
rate of feed.
Instead of being a water chamber however, this might be a transparent air
chamber, and the oil be caused to drop down through it, it only being essential
that the chamber should be transparent.
The neck & which connects the transparent chamber with the flexible metallic
connection may be of any desired length.
It may as shown in the drawings be such as to locate the reservoir close to the
crank, or the reservoir may be located in any other place and the oil be carried
thence to the transparent chamber E, and thence to the flexible connection, and so
to the crank pin.
If the device is of the telescopic form shown in the drawings, it will operate
more or less in the nature of a pump, and in that event there should be a valve F
located at the top of the transparent chamber.
So also it is preferable generally to employ a valve G for regulating the flow
of oil.
A lubricator of this character will be found to be very effective in its operation,
while the supply of oil is kept uniform and the reservoir is at all times accessible
for refilling cleansing, etcetera.

page_text: It is apparent that at the top of the flexible tubes where they connect with the
water chamber, or with the pipe leading therefrom, there is provided a flexible
joint so as to conform to the movement of the crank, and a similar flexible
connection is made at the point where it is united to the crank pin.
Having now described my invention as communicated to me I wish it to be
understood that what I desire to pretect under the Letters Patent is―
1 A crank pin oiler consisting of a stationary oil reservoir and flexible
metallic tubes connecting the reservoir with the crank pin, substantially as
described.
2nd A crank pin oiler consisting of a stationary oil reservoir, flexible metallic
tubes connecting the reservoir with the crank pin, and a transparent chamber
located between the reservoir and the crank pin, through which the oil is caused
to pass in visiblo drops, substantially as described.
3rd A crank pin oiler consisting of a stationary oil reservoir and two or
more telescopic tubes connecting it with the crank pin, substantially as
described.
4th A crank pin oiler consisting of a stationary reservoir, two or more telescopic
tubes connecting it with the crank pin, and a transparent water chamber located
between the reservoir and the crank pin through which the oil passes in visible
drops, substantially as described.
In witness whereof, I, the said William Phillips Thompson, have hereunto set
my hand and seal this fourth day of July in the year of our Lord one thousand
eight hundred and eighty three.
