"IMPROVEMENTS IN APPARATUS EMPLOYED
Lyne, in the County of Lancaster.
IN THE SPINNING OF FIBROUS MATERIALS.”
Our Invention consists in the first place of improvements in an Invention
for which Letters Patent Number 5219, of the year 1878, have been granted
to the said Thonias Marsh; and another. In the said Invention the oil rose

provided with a hinged lid to the cup, the said chamber communicating by one
passage with the said cup, and by another passage with the bottom bearing. The
oil overflowing into the cup passes thence into the said feed chamber, and so returns
to the bottom bearing. In the second place we supply lubricant by means of a
removable reservoir, which is applied to the lower part of the bolster which extends
below the rail. The said reservoir is bored to fit the exterior of the bolster, and is
held in position by means of a spring catch or of a screw, or screw-thread, or of a

projecting above the bottom of the reservoir or in a footstep prepared in the bolster,
in which latter case the lubricant has access through a spiral cut or other shaped
opening in the bolster. We do not confine ourselves to the fitting of the reservoir
upon the bolster. In the third place we form the bolster of metal tubing, and we
secure it in position by means of a split ferule arranged to be forced or screwed
into position. The footstep is formed in the lower end of the bolster or in a
separate part, in which latter case we keep the spindle from rising by means of a
ring which is sprung into a groove cut in the lower end of the spindle. In the
fourth place we form or provide the bolster with top and bottom bearings, one
bearing being cut with a right-band spiral groove, and the other with a left-hand
groove, so that the lower groove tends to cause the oil to rise in the bolster, and
the upper groove tends to prevent the oil from overflowing. We prefer to bush the
two ends of the bolster with German-silver or other suitable metal tubes, which
are cut through spirally. In the fifth place we form the sleeves of thin tubing, and
cast the "whorl" on one end of such tubing, the other end being soldered to a block
which is forced on the spindle, the sleeve being kept concentric by means of a

to some extent by forming it as a split bobbin, the lower end being surrounded by a
ring of steel or other suitable material which is sprung into a groove. A remaining
part of our Invention relates to the rings and holders. We form a reversible ring
which we spring into an undercut groove in a split ring holder. The outer flanch
of the ring and the said groove are both excentric, so that the ring can be adjusted
to the spindle by turning the ring round. In other forms of reversable rings we
form a collar on the ring by turning a groove in the ring and springing a steel or
metal wire ring into such groove, whereby we reduce the cost of making the said
rings. We may combine together two or more of the parts of our Invention.
