JAMES MARSH of Ashton-under-Lyne in the County of Lancaster Machinery
Agont, "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 the 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 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
cach perforated with a number of holes for spindles to pass through. Instead of
using an outer sleeve as herein before 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 the starch and fly the clogging which ordinarily
takes place is prevented and the cop bottoms are kopt clean.
My Invention relates in the second place to the spindles of ring spinning
machinery. In one arrangement I employ an outer shell as in the first part of my

page_text: 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 into 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.
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 numbered 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 projects
forward below the rail and can be readily supplied with lubricant.
