Improvements in Spindle Supports for Spinning Machines.
I, THOMAS GORMAN, of the Town of Warren, County of Bristol, and State of
Rhode Island. United States of America, Boss Spinner, do hereby declare the
nature of my. invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
The present invention relates to the manner of supporting the spindle of spinning
machines, and consists primarily in the combination with bolster and step rails of a
bolster bearing loosely mounted in the bolster rail, a separate step bearing fixed in
the step rail, and a spindle supported in said bearings with its whirl above both.of
said bearings.
The invention further consists in certain combinations and. arrangements of parts
hereinafter described.
Referring to the drawings,
Fig. 1 represents a front elevation, partly in section, of bolster and step rails
with two spindles mounted thereon; Fig. 2 is a top view of the same;
Fig. 3 is a transverse section on the line x, x of Fig. 2;
Fig. 4 is a top view; and Fig. 5 a front elevation of the bolster bearings.
In the drawings I have shown my invention as applied to a spinning machine in
which, while two separate rails are employed, the upper or bolster rail is supported
upon the lower or step rail, and only the latter rail is directly secured to the frame,
thus requiring but a single line of brackets for supporting both rails; but my
invention may be employed, if desired, in a machine in which the bolster and step
rails are supported upon separate lines of brackets and each rail thus secured
directly to the frame.
The lower or step rail A shown in the drawings is to be secured to the frame of
a spinning machine by means of supporting brackets in the usual manner. This
step rail may be of any desired or convenient length to contain any, desired number
of spindles. I prefer to construct said step rail in the form of a trough enclosed at
the ends, sides and bottom, in order that it may serve as an oil receptacle for all of
the spindles mounted thereon.
The upper or bolster rail B is supported upon the lower or step rail, and when
said step rail is constructed in the form of a trough the bolster rail is preferably
constructed to fit within said step rail as shown in the drawings. In such case the
step rail is preferably provided with an offset or ledge a at each end, upon which
ledges the ends of the bolster rail rest, as shown in Fig. 1. The bolsters bare
fitted loosely in the bolster rail, and so as to have a certain amount of lateral play
therein. Each bolster 6 is provided at its upper end with projecting lugs 6
adapted to enter and engage with a longitudinal groove e formed in the upper
surface of the bolster rail, as shown in Figs. 1 and 2, whereby the bolster is
prevented from turning with the spindle. If desired, also, said projecting lugs 61
may serve as means for supporting the bolster vertically in the rail.
The bottom of the bolster rail B is preferably cut away upon each side of the
bolster, as at y, y, Fig. 3, so that only the central longitudinal portion of the
bolster rail is the full depth of the bolster, and so that the receptacle formed by
the step rail A may be filled with oil to a level above the lower ends of the bolster.
Transverse holes d, d, are made in the downwardly projecting portion of the bolster
rail, which said holes communicate with corresponding holes in the side walls of the

page_text: bolsters, all as shown in Fig. 3, and by means of which the oil may be conducted to
the spindle to lubricate the bolster bearings. This cutting away of the bolster rail
and the formation of the oil passages referred to, however, are not necessary, as the
bolster bearings may be properly lubricated by the sucking action induced by the
high revolution of the spindle, which, as is well known, will operate to draw up
from the receptacle a sufficient quantity of oil between the bolster and the spindle
to properly lubricate the bolster.bearings.
The steps s are firmly secured in the step rail A, and when the receptacle formed
by the step rail is filled with oil, the step bearings will be immersed in the oil and
will thus be thoroughly lubricated.
The spindle C is provided with the usual whirl e, which said whirl is located
above both the bolster and step bearings, and preferably only a short distance
above the upper end of the bolster bearing, as shown in the drawings.
With the combination and arrangement of parts above described, that is, with
separate bolster and step bearings, the bolster bearing being loose in its supporting
rail, and the step bearing being fixed in its supporting rail, and with the spindle
supported in said bearings, with its whirl located above both of the bearings, a high
speed of revolution may be obtained without chattering, while the location of the
whirl above both bearings permits the spindle to be removed when desired with the
same facility as in a single rail machine in which a combined bolster and step and a
sleeve whirl spindle are employed.
Moreover by employing the construction and arrangement of rails shown in the
drawings, in which the upper or bolster rail is supported upon the lower or step
rail, and in which only the step rail requires to be directly secured to the frame,
thus requiring only a single line of brackets for supporting both rails, the invention
may be readily applied to such single rail machines by simply substituting the
double rail with separate bearings for the single rail and combined bolster and
step bearings of said machine.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination of a step rail, a step bearing fixed in said step rail, a bolster
rail, a bolster bearing loosely mounted in said bolster rail, and a spindle supported
in said bearings with its whirl located above both of said bearings, substantially as
described.
2. The combination of a step rail, a step bearing fixed in said step rail, a bolster
rail, a bolster loosely mounted in said bolster rail, said bolster being provided at or
near its upper end with one or more lugs or projections by means of which said
bolster may be supported vertically in said bolster rail, aud a spindle supported in
said bearings with its whirl located above both of said bearings, substantially as
described.
3. The combination of a step rail, a step bearing fixed in said step rail, a bolster
rail provided with a groove or recess in its upper face, a bolster bearing loosely
mounted in said bolster rail, said bolster bearing being provided at or near its
upper end with one or more lugs or projections adapted to enter said recess in the
bolster rail to prevent the bolster from turning in said rail, and a spindle supported
in said bearings with its whirl located above both of said bearings, substantially as
described.
4. The combination of a step rail adapted to be secured to the frame of a
spinning machine, a step bearing fixed in said step rail, a bolster rail supported by
said step rail, a bolster bearing loosely mounted in said bolster rail, and a spindle
supported in said bearings with its whirl located above both of said bearings,
substantially as described.
5. The combination of a step rail adapted to be secured to the frame of a
spinning machine, said step rail being constructed in the form of a trough to form
an oil receptacle, a step bearing fixed in said step. rail, a bolster rail supported by

page_text: said step rail, a bolster bearing loosely mounted in said bolster rail, and a spindle
supported in said bearings with its whirl located above both of said bearings,
substantially as described.
