Year: 1885

page_text: I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake, and Co, Patent Agents,
Southampton Buildings, in the County of Middlesex do hereby declare the nature
of my invention for "IMPROVEMENTS IN AND RELATING TO BOLSTER AND STEP
BEARINGS FOR SPINDLES to be as follows:-
"
This invention relates to that class of spindle supports known as "bolsters and
steps," which have a limited freedom of movement laterally; and its objects are
to provide a step which will permit such movement, which will not become "set"
or fast in the metal tube which supports the step, and which while connected to
the bolster, will permit of its interior surface, and that of the bolster, being
readily visible. I obtain these objects by means of the mechanism hereinafter
described.
According to the said invention the supporting-case rests on the rail, and is.
provided at its lower end with a widened base which rests on the rail when placed
in the spinning-frame; and with a downwardly projecting part which is placed in
an opening in the rail of the frame to maintain it in operative position. United
to the case is an oiling-tube through which oil is supplied to the spindle.
The lower end of the spindle, rests on a step, and is supported above and near
its lower end by a bolster. The step stands on the metal forming the bottom of
the case.
The upper part of the step and bolster is surrounded by a fibrous cot or
tube which prevents the metal of the bolster from coming into contact with the
metal of the supporting case, and gives a necessary freedom of movement laterally
to both the bolster and step; in order that the spindle may adjust itself
perpendicularly when rotating, or so that the centre of gravity may correspond to
the axis of rotation.
The spindle is provided with a skirt and whirl in the usual manner well known
in the construction of spindles of this class.
The cot is attached to the step by winding a cord around it and drawing it into
a groove formed around the step, so that the step and bolster, when once put
together in the cot, will so remain while being placed in the case, or while being"
removed therefrom.

page_text: The step is constructed of glass, which practically prevents its adhering or
becoming set to the case upon which it rests, because the materials in contact are
not the same, or of an analogous substance and nature, and consequently do not
act upon each other, and upon the oil between and in contact with them, to cause
them to adhere the one to the other.
Hertofore the step and containing case have been constructed of metal, but
the lubricant must enter the case, and consequently always surrounds the step, and
from the movement of the latter and the gravity of the oil it enters between the
bottom of the step and the case, where the action of the thin stratum of oil
between the surfaces of the lower end of the step and the bottom of the metal
case, resting one upon the other, caused them to adhere through the condensing of
the oil, and prevented the necessary freedom of movement laterally, which the
step should, and must, have for continued and successful operation, and to prevent
its being worn by the spindle whilst spinning, because if the step does not move
laterally with the bolster the spindle must either move across the top of the step,
and be thereby disturbed in its movements, or standing in one place on the step
gyrate and wear the step to such great degree that much greater lateral movement
is given to it and the bolster by such disturbance or gyration, and the spinning is
interfered with. The fibrous cot containing the bolster and step is also broken
and destroyed near the point of juncture of the two by such movement. Thus
the oil in the case is constantly rendered less suitable for lubrication by the heat
evolved, and the step more firmly glued by the oil in its position. This action
of the oil on the cot, step, and bolster exists with metal steps and cases to so great
a degree that a large proportion of such steps and cots must be removed and
replaced by new ones within a few months of their being placed in use, the oil
becoming thick, gummy, and difficult to wash out, and the steps irregularly worn,
and the cots broken and disintegrated near the point of contact of the step and
bolster. With ny device, using a glass step, no trace of such destructive wear
upon the step and cot can be seen, and the oil remains clear in color and free from
gumminess for many months, and the step and bolster are always free to move
together, so that no impairing action upon the spinning ever takes place. Another
advantage of the glass step is that when it, together with the cot and bolster, is
withdrawn from the case the interior of the bolster is readily visible, because the
observer can look in at the open end while the light is admitted through the step,
while with the metal step no such view of the interior can be obtained without
separating the parts.
It is obvious that some of the advantages of a glass step may be obtained by
using other vitreous substances, and some by interposing a disc of glass between.
the bottom of the metal step, as heretofore constructed, and the case.

CONFUETE DI ECIFICATION.
I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake and Co, Patent Agents,
Southampton Buildings, in the County of Middlesex do hereby declare the nature.
of my invention for IMPROVEMENTS IN AND RELATING TO BOLSTER AND STEP
BEARINGS FOR SPINDLES" 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 that class of spindle supports known as " bolsters and
steps" which have a limited freedom of movement laterally; and its objects are to
provide a step which will permit such movement, which will not become "
"
set or
fast in the metal tube which supports the step, and which, while connected to the
bolster, will permit of its interior surface and that of the bolster being readily
visible. I obtain these objects by means of the mechanism hereinafter described.
In the accompanying drawing,
Figure 1 is an elevation of a spindle with its bolster, step, and supporting parts
shown in section.
Figure 2 is a view showing the step, bolster, and elastic packing removed from
the supporting-case..
A is the supporting case which rests on the rail, and which is provided at its
lower end with a widened base a which rests on the rail when placed in the.
spinning-frame; and with a downwardly projecting part a² which is placed in an
opening in the rail of the frame to maintain it in operative position. United to
the case is the oiling-tube B, through which oil is supplied to the spindle.
C is the spindle, whose lower end rests on the step c, and is supported above and
near its lower end by the bolster d. The step stands on the metal forming the
bottom of the case A. The upper part of the step and bolster are surrounded by
the fibrous cot or tube e which prevents the metal of the bolster from coming into
contact with the metal of the supporting-case, and gives a necessary freedom of
movement laterally to both the bolster and step, in order that the spindle may
adjust itself perpendicularly when rotating, or so that the centre of gravity may
correspond to the axis of rotation.
The spindle C is provided with the skirt f and whirl
known in the construction of spindles of this class.
g in the usual manner well
The cot e, as shown in the drawings, is attached to the step by winding a cord
around it and drawing it into the groove formed around the step, so that the step
and bolster, when once put together in the cot will remain so while being placed in
the case, or while being removed therefrom.
The step c is constructed of glass, which practically prevents its adhering or
becoming set to the case upon which it rests, because the materials in contact are
not the same, or of an analogous substance and nature, and consequently do not
act upon each other, and upon the oil between and in contact with them, to cause
them to adhere the one to the other.
Heretofore the step and containing-case have been constructed of metal, but the
ubricant must enter the case, and consequently always surrounds the step, and from

page_text: the movement of the step and the gravity of the oil, it enters between the bottom
of the step and the case. Here the action of the thin stratum of oil between the
surfaces of the lower end of the step and the bottom of the metal case, resting one
upon the other, caused them to adhere through the condensing of the oil, and
prevented the necessary freedom of movement laterally, which the step should and
must have for continued successful operation, and to prevent its being worn by the
spindle while spinning; because if the step does not move laterally with the bolster
the spindle must either move across the top of the step, and be thereby disturbed
in its movements, or standing in one place on the step gyrate and wear the step to
such great degree that much greater lateral movement is given to it and the bolster
by such disturbance or gyration, and the spinning is interfered with. The fibrous
cot containing the bolster and step is also broken and destroyed near the point of
juncture of the two by such movement. Thus the oil in the case is constantly
rendered less suitable for lubrication by the heat evolved, and the step more firmly
glued by the oil in its position. This action of the oil on the cot, step, and bolster
exists with metal steps and cases to so great a degree that a large proportion of
such steps and cots must be removed and replaced by new ones within a few months
of their being placed in use, the oil becoming thick, gummy, and difficult to wash
out, and the steps irregularly worn, and the cots broken and disintegrated near the
point of contact of the step and bolster.
With the improved device, by using a glass step, no trace of such destructive
wear upon the step and cot can be seen, and the oil remains clear in color and free
from gumminess for many months, and the step and bolster are always free to move
together, so that no impairing action upon the spinning ever takes place. Another
advantage of the glass step is that when it, together with the cot and bolster, is
withdrawn from the case the interior of the bolster is readily visible, because the
observer can look in at the open end while the light is admitted through the step,
while with the metal step no such view of the interior can be obtained without
separating the parts.
It is obvious that some of the advantages of a glass step may be obtained by
using other vitreous substances, and some by interposing a disc of glass between the
bottom of the metal step, as heretofore constructed and the case. Such constructions
are no departure from the spirit of my invention.
I am aware of the fact that a glass step has been used in places where no freedom
of movement was necessary, and consequent action of the oil possible.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed I declare that what
I claim is
First. The combination of the spindle C, its metal oil-holding case A and the
vitreous step c fitting loosely within the case and resting its vitreous surface upon
the metallic surface of the latter, substantially as described.
Second. The combination of the spindle C, the metal oil-holding case A, the
bolster d, the fibrous cot e, and the loosely-fitting step c resting its vitreous surface
upon the metallic bottom of the case, substantially as described.
Dated this 19th day of March 1885.
