Year: 1878

page_text: LETTERS PATENT to James Clarence Stanley, of New Hartford, in the State
of Connecticut, United States of America, Manufacturer, for the Invention of
"IMPROVEMENTS IN SPINNING MACHINES."
Sealed the 14th January 1879, and dated the 29th July 1878.
PROVISIONAL SPECIFICATION left by the said James Clarence Stanley at
the Office of the Commissioners of Patents on the 29th July 1878.
JAMES CLARENCE STANLEY, of New Hartford, in the State of Connecticut, United
States of America, Manufacturer. "IMPROVEMENTS IN SPINNING MACHINES."
This Invention relates to an improvement in the spinning rail of that class of
spinning machines in which the spindles have no bearing above the whirl or pulley
on the spindle by which it is driven.
The spinning rail, which is a part of the spinning frame, is inade of a solid con-
tinuous piece of metal of sufficient length for a series of spindles, and contains
within itself or is constructed with a series of chambers, usually vertical, each of
which is a receptacle for and holds a single spindle and its bolster or casing, and
also forms an oil chamber for the spindle. The spindle bolster fits nicely within
such chamber for a sufficient length to keep the spindle true and steady and in
proper position, having shoulders upon it to rest upon the top of the rail, and is
held therein by means of set screws, such bolster forming a casing for the spindle,
except as to that part which carries the quill and the whirl. Within such rail is a
common oil duct, which communicates with all the several chambers therein, so that
all the spindles may be oiled at one and the same time, and whether they are at
rest or in motion, which oil duct is supplied with oil by a cup placed on any desired
part of the rail.
The spindle bolster or casing carries the step bearing for the lower end of the
spindle, and also forms the upper bearing of the spindle. It is also constructed
with a cup at or near its upper end to catch any oil that may pass over its top,
over which is a reversed cup forming part of the whirl, which prevents the escape
of such oil and the entrance of dust. Such oil passes by means of suitable ducts
in the sides of the bolster down to the common oil chamber, and oil passes to the
spindle through similar ducts in the lower end of the bolster.

the said James Clarence Stanley in the Great Seal Patent Office on the
28th January 1879.
JAMES CLARENCE STANLEY, of New Hartford, in the State of Connecticut, United
States of America, Manufacturer. "IMPROVEMENTS IN SPINNING MACHINES."
This Invention relates to an improved construction of the spinning or spindle rail
in that class of spinning machines in which the spindles have no bearing above the
whirl or the small pulley on the spindle by which it is driven.
The Invention consists in making the spindle rail, which is a part of the frame,
in a solid continuous piece of metal, containing within itself a series of chambers,
each of which is a receptacle for a spindle and its bolster, and forms also an
oil chamber for the spindle, and having all such chambers communicate with each
other by a common oil duct, by means of which all the spindles can be oiled at one
and the same time, and whether they are at rest or in motion, and oil can be at one
time supplied in quantity sufficient to last a long time.
Figure 1 is a view of a portion of a rail containing two spindles in proper
position, partly in vertical cross section, showing the spindle and its bolster in the
chamber, and the common oil duct near the top of the rail.
Figure 2 is a view, partly in section, showing a spindle rail having the continuous
oil duct at or near the bottom of the rail.
A, A, is a portion of the spinning rail, which forms a part of the frame, made or
cast of metal in one solid continuous piece of sufficient length for a series of
spindles, and contains wholly within itself a series of chambers a corresponding
with the number of spindles, each of which is constructed or adapted to receive a
spindle B and its bolster or casing b, and gives support to nearly the whole length
of the bolster, and through it to the spindle, and also forins an oil chamber to the
spindle. An oil duct C formed wholly within the rail A communicates with all the
chambers a, and to this oil duct oil is supplied by means of an oil cup D, through
which all the spindles may be oiled at the same time and by one operation, and
whether they are at rest or in motion, and with sufficient quantity to last for a long
time.
The spindles B revolve within their bolsters or casings b, which are non-rotary,
and such casings form the upper bearings of the spindles, the spindles being cylin-
drical for a part of their length 1, 1, corresponding with the upper ends of the
bolsters, and for a length to give a sufficient bearing in the bolsters, and tapering
for the rest of their length above and below such bearing.
To the lower end of the bolster or casing b is connected the bolster end c, which
carries or forms the step bearing d for the lower end of the spindle. In the bolster
or casing b, and near its upper end, is formed a cup e to receive any overflow of the
oil over the top of the casing, and leading from such cup are ducts f. which permit
any oil received in such cup to flow downward into the chamber and oil cup a.
The oil is admitted to the interior of the casing and to the spindle from the
chamber a by means of openings h, h. The bolsters or casings b rest by shoulders i, i,
upon the top of the rail, and are kept in proper position in the rails by the
bearings j, j, and are held in position by the set screws k.
Around the lower ends of the spindle B, and just above its step bearing d, is a
conical nut, having cut in its periphery a spiral groove l¹, by means of which the
oil as the spindle and nut revolves is continually forced or carried up around the
spindle, thus securing a more abundant and constant lubrication than would other-.
wise be obtained. This grooved nut should be slightly smaller than the casing in
which it revolves, and have no contact with the sides of the casing. The groove is
thus prevented from becoming filled or choked by any dust or sediment that may
enter or gather in the oil chamber a, and which would be likely to enter and be
pressed into the groove if the nut was in close contact with the casing. The nut

page_text: also acts as a collar to prevent, by coming in contact with the shoulder m, the
spindle rising out of its bearing d.
The bolsters b, instead of being supported in the rail by shoulders, and being
secured therein by screws, as above described, may be screwed into the rail if
desired in any special case, or may be connected therewith and secured thereto in
any convenient and sufficient manner.
The construction of the spindle rail before described will admit the use there-
with of any self-oiling spindle, and whether with or without the conical grooved
nut . Such grooved nut is however of great practical value, as it secures more
abundant and uniform lubrication, and a more perfect operation of the spindles.
The construction of rail shown in Figure 2, in which the continuous oil duct is
placed in the lower part of the rail, is more particularly convenient for cleaning
the oil chambers in which the spindles stand.
In the construction of rail shown in Figure 1, when it becomes necessary to clean
the spindles and oil chambers, the spindles have to be taken out of their chambers,
and then the chambers pumped out or cleaned by something inserted in them.
In the other construction of rail all the chambers a open at their lower ends
directly into the common oil duct C, and from this there is a discharge orifice on
the under side of the rail, which is closed by a cap nut. To clean the chambers it
is only necessary to take off this nut and allow the oil to run out, and should the
spindles prove to be gummed the duct and chambers can be filled with benzine
or any other liquid that will remove the gum and cleanse the parts, and after this
is drawn out fresh oil can be at once supplied, and the spindles are again ready
for use.
With a construction of rail such as is above described the spindles can be run for
a year or more without cleaning their oil chambers.
What is claimed is, a solid metallic spindle rail A containing within itself a series
of chambers a, which receive the spindles and their casings, and which also serve
as oil chambers, and having a continuous oil duct C communicating with all the
chambers placed either at the top or bottom of the rail, substantially as and for the
purposes set forth.
In witness whereof, I, the said James Clarence Stanley, have hereunto set
my hand and seal, this Ninth day of January, in the year of our Lord
1870
