Improvements in Bolster-bearings for Spinning-machine and
like Spindles.
1, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of this invention to be as follows:-
This invention relates to a bolster bearing for spindles, such as are used on
slubbing, intermediate, roving, and fly frames, the object of the invention being to
provide means for keeping the bearing properly lubricated, with less cost and
expenditure of time on the part of the attendants than is required with bolster
bearings now commonly used.
In order to accomplish this result the bearing sleeve, which is screwed or other-
wise fastened in the usual manner to a base in the rail or rail bracket, communicates
near its lower end with an oil reservoir or chamber in the rail or bracket, and the
bearing is provided near its top and bottom with packing rings which are contained
in recesses in the bearing and clasp about the spindle so as to obstruct passage of
oil outward along the spindle, from the bearing surface, and also to prevent admission
of dust or grit to the bearing surface.
In carrying the invention into practice the bearing sleeve has a screw threaded
portion near its lower end by which it is securely fastened in the base which may be
the usual rail or rail bracket. The said sleeve is provided with an extension below
the threaded portion which enters a recess in the base and is provided with slits
that afford communication between the interior bore or bearing surface of the sleeve
and the recess in the base.
The recess around the lower end of the sleeve communicates through a passage
with an oil reservoir in the bracket the said passage passing through an interme-
diate chamber which is filled with wicking or other absorbent material to prevent
too rapid flow of the oil to the bearing surface.
The annular recess around the lower end of the sleeve is also filled with wicking
or fibrous material which tends to regulate the flow of oil to the slots in the lower
end of the sleeve and to the bearing surface within the sleeve.
In order to retain the oil on the bearing surface and to prevent admission of
dust or grit to the bearing surface, the sleeve is provided at its upper end, with an
internal groove which receives a split ring that tends to close by its elasticity
tightly upon the spindle that has its bearing in the sleeve, and a similar split ring is
employed in a similar groove near the lower end of the bearing opening in
the base.
The oil reservoir is provided with a pivoted cover so that the reservoir may be
uncovered to renew the lubricant from time to time when necessary.
"
By the herein described construction the spindle may be run for a very long
time without attention, instead of requiring that the bolster hearing should be
lubricated at frequent intervals as is the case with the bearing as now commonly
used.

1, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent
Agents, 45, Southampton Buildings, in the County of Middlesex, 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:-
This invention relates to a bolster bearing for spindles such as are used on slubbing,
intermediate, roving, and fly frames, the object of the invention being to provide
means for keeping the bearing properly lubricated with less cost and expenditure of
time on the part of the attendants than is required with the bolster bearings now
commonly used.
In order to accomplish this result the bearing sleeve which is screwed or other-
wise fastened in the usual manner to a base in the rail or rail bracket, communicates
near its lower end with an oil reservoir or chamber in the rail or bracket, and the
bearing is provided near its top and bottom with packing rings which are contained
in recesses in the bearing and clasp about the spindle so as to obstruct the passage
of oil outward along the spindle, from the bearing surface, and also to prevent the
admission of dust or grit to the bearing surface.
In the accompanying drawing I have shown how my said invention may be con-
veniently and advantageously carried into practice.
Figure 1 is a side elevation partly in section of a bearing sleeve embodying this
invention, the rail bracket in which it is supported being shown in section.
Figure 2 is a plan of the same.
Figure 3 is a sectional view of the lower portion of the bearing sleeve with the
adjacent portion of the bracket, and
Figure 4 a plan of the lower end of the bearing sleeve detached from the
bracket.
In carrying the invention into practice the bearing sleeve a has a screw threaded
portion a near its lower end, by which it is screwed into the base b which may be
the usual rail or rail bracket. The said sleeve a is provided with an extension a³
projecting below the screw-threaded portion and entering a recess 62 in the base.
The said extension is provided with slots a' that afford communication between
the interior bore or bearing surface of the sleeve and the recess ² in the base.
The said recess 2 around the lower end of the sleeve communicates through a
passage c with an oil reservoir d in the bracket, the said passage passing through
an intermediate chamber e which is filled with wicking or other absorbent material
to prevent too rapid flow of the oil to the bearing surface.
The annular recess 62 around the lower end of the sleeve is also filled with wicking
or fibrous material which tends to regulate the flow of oil to the slots a* in the
lower end of the sleeve and to the bearing surface within the sleeve.
In order to retain the oil on the bearing surface and to prevent admission of dust or
grit to the said bearing surface, the sleeve a is provided at its upper end with an
internal groove a³ which receives a split ring that tends to close by its elasticity.
tightly upon the spindle that has its bearing in the sleeve, and a similar split
ring g is employed in a similar groove near the lower end of the bearing opening
into the base.
The oil reservoir d is shown as provided with a cover d² pivoted at d³, so that
the reservoir may be uncovered to renew the lubricant from time to time when
necessary.
By the herein described construction the spindle may be run for a very long time
without attention, instead of requiring the bolster bearing to be lubricated at
frequent intervals as is the case with the bearing as now commonly used.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed as communicated to me by
my foreign correspondents I declare that what I claim is :-
First. A bolster bearing for a spindle comprising a sleeve and a supporting base
therefor, provided with an oil chamber communicating with the bearing surface of
the sleeve, and packing rings near the ends of the bearing surface, to obstruct the
escape of lubricant, substantially as described.
Second. The combination of the base and sleeve fastened therein, having a
slotted extension contained in a recess in said base, which is provided with an oil
reservoir communicating with said recess and an absorbent or fibrous filling in said
recess, and packing rings near the ends of the bearing surface substantially as and
for the purpose described.
