JAMES MARSH of Ashton-under-Lyne in the County of Lancaster, Machinery
Agent, "IMPROVEMENTS IN MOUNTING AND LUBRICATING THE SPINDLES OF
TEXTILE MACHINERY
""
My Invention relates in the first place to mule spindles. I mount each spindle
in a long bolster which is carried by an outer tubular shell which is screwed or
fixed to or formed upon a bracket which is secured to the underside of the top rail.
The lower end of the bolster or of the outer shell is formed' or provided with an oil
cup from which oil flows to the bottom bearing of the spindle and is lifted to thie
top bearing by means of a screw groove. A boss upon the said bracket or upon
the upper end of the said shell forms a cup into which the oil overflows and
passages are formed by grooving the shell or the bolster to convey the oil into the
lower annular space between the bolster and the said shell which projects
downwards to the oil cup. The lower oil cup is provided with a cover which slides
upon the said shell.
The said whirl is formed with a short sleeve which by
preference comes level with or a little below the top of the rail and the said whirl
is formed with a lip which enters the upper cup the line of pull of the band being
a little below the upper bearing. The top rail is recessed so that the spindle can
be lifted out and I cover these recesses by means of removable plates which are
each perforated with a number of holes for spindles to pass through. Instead of
using an outer sleeve as hereinbefore described I may connect the upper cup with
the lower oil cup by means of a tube. The bottom oil cup may either be cast in
one piece with the bolster or may be formed separately and be, bored to receive the
lower end of the bolster. Instead of each spindle having a separate oil cup a long
chamber may be connected with the lower ends of a number of bolsters and be
provided with a removable cover or with hinged lids or with a cover in two or
more parts. A mule spindle mounted as described can be run with a considerably
less expenditure of oil and power as compared with ordinary mule spindles and as
the bearings are protected from starch and fly the clogging which ordinarily takes
place is prevented and the cop bottoms are kept clean.
My Invention relates in the second place to the spindles of Throstles and other
spinning machinery. In one arrangement I employ an outer shell as in the first
.

page_text: part of my invention but I cast or form the oil cup upon the said shell or fix it
thereon and provide it with an upward sliding cover. The upper end of the said
shell or a nut or screwed collar thereon screws upon a tubular bolster carrier and
serves to secure the parts to the rail which is nipped between collars on the bolster
carrier and shell. The lower end of the bolster extends into a recess in the bottom
of the shell and oil from the cup flows through a hole in the said recess and passes
to the bottom bearing in the bolster. The oil rising in the bolster and overflowing
is conveyed by slots in the interior of the bolster carrier or the exterior of the
bolster or by suitable ducts into the said shell and thence can pass through a second
hole into the oil cup. In a modification the bolster is secured in the said shell
which is secured by means of nuts to the rail In another arrangement the spindle
revolves in an upper and a lower bolster. A footstep for the spindle is formed at
the bottom of the lower bolster and communicates with a bottom oil cup or
reservoir. At the upper end of the lower bolster is formed an oil chamber which
is preferably turned with a contracted mouth to prevent the overflow of oil. The
"whirl" is formed at the upper end of a cup which projects downwards into the
said chamber, and is perforated or slotted at its lower end: The lower end of the
upper bolster projects into the cup on the whirl. A screw thread is formed on the
lower part of the spindle extending into the aforesaid oil chamber. The oil is
lifted into the said chamber and passes into the whirl cup whence it has access to
the upper bolster and rising therein overflows at the top or through perforations
between the top and the bottom rétúrning outside the bolster and through ducts
in the bolster-carrier to the said oil chamber. In some cases I mount a thimble
to carry the bobbin on the upper bolster the said thimble covering the overflow
passages.
According to a remaining part of my invention I supply' oil to the lower
ends of bolsters by means of oil troughs provided with hinged or removable lids
similar to the troughs described as being used to supply oil to footsteps in the
specification of Letters Patent dated the first day of May, 1876 and number 1815
granted to me conjointly with others. Each trough may supply only one bolster
or a number of bolsters. The oil passes from the trough into an annular space
surrounding the bolster and flows through an aperture or slot to the bottom bearing
The oil overflowing is returned by ducts or passages into the trough. The trough
project's forward below the rail and can be readily supplied with lubricant.
