WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "AN IMPROVED LUBRICATING ARBOR OR SPINDLE,
CHIEFLY DESIGNED FOR THE DRAWING ROLLERS OF SPINNING MACHINERY." [A
communication from abroad by Aaron White Cook Williams and Caleb McKinney
Talcott, both of Hartford, Connecticut, United States of America.]
The said Invention relates to novel means for automatically lubricating rollers or
rolls that run loosely upon fixed or stationary arbors, axles, shafts, or spindles, and
is chiefly designed to prevent the necessity for frequent removal and lubrication of
the top rollers of spinning machines heretofore necessary.
The said Invention consists in the means whereby I provide in the spindle arbor
or shaft a reservoir capable of containing a sufficient quantity of oil to lubricate the
roller and its journal for a very long time, and which will not permit any of the
oil to escape or flow from the said reservoir except when the roller is running.
The said reservoir is formed by boring the arbor or spindle, or otherwise making
the same hollow or tubular for the whole or a portion of its length.
In the case of the aforesaid drawing rollers the arbor or spindle is formed to carry
two rollers, and there is a separate reservoir for each roller, each reservoir extending
lengthwise nearly to the centre of the said arbor. In the end of the said arbor I
fix a screw plug or other suitable stopper, which closes air-tight the end of the

page_text: reservoir, but which may be removed to permit the same to be filled. Through the
side of the arbor or spindle a small hole is drilled to form a passage for the oil from
the reservoir to the inner surface of the roller for the purpose of lubricating the
same. Into this hole I insert a plug, which so nearly closes the said hole that no
oil will flow from the same when the roller is not running or in motion thereon.
But when the said roller is running, that is to say, when lubrication is required, the
action of the roller upon its spindle causes the oil to flow through the said small
hole, and thereby keep the bearing surfaces of the arbor and roller continually and
uniformly lubricated.
In some instances a wick may be employed to conduct the oil from the reservoir
to the surfaces of the roller and its arbor or spindle.
With the reservoir provided in the arbor or spindle, and closed with an air-tight
plug or stopper, as above described, the said reservoir will contain sufficient oil to
lubricate the roller for many months, and by means of the small pin or wick the oil
will be so supplied to the bearing surfaces that the said roller during that time will
not need removal from its spindle.

WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "AN IMPROVED LUBRICATING ARBOR OR SPINDLE,
CHIEFLY DESIGNED FOR THE DRAWING ROLLERS OF SPINNING MACHINERY." A
communication from abroad by Aaron White Cook Williams and Caleb McKinney.
Talcott, both of Hartford, Connecticut, United States of America.
The said Invention relates to means for automatically lubricating rollers or
rolls that run loosely upon fixed or stationary arbors, axles, shafts, or spindles, and
is chiefly designed to prevent the necessity for frequent removal and lubrication of
the top rollers of spinning machines heretofore necessary.
The said Invention consists in the peculiar device or means whereby a spindle,
arbor, or shaft provided with an internal reservoir is rendered capable of containing
or holding the oil in such a manner that it will not permit any of the oil to escape
or flow from the said reservoir except when the roller is running, but will lubricate
the said roller freely when the same is running.
The said Invention is illustrated in the accompanying Drawing, in which,―
Figure 1 is an exterior view of a spindle or arbor, with two drawing rolls fitted
to turn thereon.
Figure 2 is a longitudinal section of the same.
Figure 3 is a transverse section on the line x, x, Figure 1.
Like letters indicate the same parts throughout the Drawing.
a is the spindle or arbor; b, b, are the rolls.
The reservoir e is formed by boring the arbor or spindle a, or otherwise making
the same hollow or tubular for the whole or a portion of its length. In drawing
machinery the arbor or spindle a is sometimes formed to carry one roll, but I have
shewn it provided with two rolls b, b, and there is a separate reservoir c formed in
the arbor for each roll, each reservoir extending lengthwise nearly to the centre of
the said arbor, as shewn in Figure 2. In each end of the said arbor I fix a screw
plug d or other suitable air-tight stopper, which closes the end of the reservoir, but
which may be conveniently removed to permit the same to be filled.
The peculiar device or means whereby the object of this Invention is accomplished
is as follows, that is to say-Through the shell or substance of the hollow arbor or
spindle a small hole e is drilled to form a passage for the oil from the reservoir to
the inner surface of the roller for the purpose of lubricating the same, and in
combination with this hole I insert a pin or plug f, rivetted or otherwise secured in
the arbor or spindle, as shewn at g, with its extremity projecting into the said hole,
which it so nearly closes that no oil will flow from the same when the roll or roller
is not running or in motion.
The hole e is preferably formed at the under side of the spindle or arbor a of the
top roll, and by reason of the pressure of the bottom roll the interior surface of the .
top roll covers and closes the hole e. Therefore when the roll b is not running any
oif that might pass the pin ƒ would not escape from the said hole, but when the roll
is running it draws or pumps the oil from the reservoir with sufficient force to cause
the oil to flow through the very slight annular space between the pin f and the sides
of the said hole, and thereby keeps the bearing surfaces of the arbor and roller
continually and uniformly lubricated, the quantity of oil being all the time just
sufficient for proper lubrication of the roll without any waste. The hole e is recessed
or countersunk on the outside of the spindle, as shewn, to permit the oil to flow
freely in all directions after passing through the said hole.
Instead of the pin f, arranged as shewn, I may use a small screw inserted in the
arbor with its head nearly closing the hole e.

page_text: I wish it understood that I am aware that the use of a spindle or arbor with an
internal reservoir for oil, closed at the end and provided with a side aperture for the
passage of the oil to the roll or wheel running on the spindle is not new, but such
an arrangement does not restrain the flow of the oil, and therefore the same escapes
at all times whether the rolls are running or at rest; consequently there is a great
waste of oil and the reservoirs require continual supervision and frequent replenish-
ment, and very little if any advantage over the ordinary method of lubricating by
hand is obtained.
But by the use of the small pin or plug with its end projecting into and nearly
closing the hole in the reservoir when the latter is otherwise hermetically closed, I
obtain the very important advantage of a constant and uniform supply of oil to the
bearing for a long time (in some cases for many months) without the necessity of
removing the rolls from their arbors or refilling the reservoirs. And therefore I am
enabled to effect great economy in the consumption of oil and in the cost of super-
vision of the rollers.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Eighteenth day of March, in the year of our Lord
One thousand eight hundred and seventy-nine.
