Improvements in or relating to the Lubrication of Spinning and
Doubling Rings.
I JAMES LONGMORE, Spinner, 34 Leadenhall Street London 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 the lubrication of the spinning and doubling rings used
in spinning machinery.
The grease is usually applied by rubbing it on the flange of the ring with the
finger. This method is open to the objection that it entails much waste of time in
stoppages and requires frequent repetition, and causes irregularity in the amount of
grease applied which if in excess is apt to clog and collect fly.
In the present invention the grease is supplied with regularity at the exact point
of contact of the traveller with the ring where only it is required, and the traveller
is kept nicely lubricated one or more times in every revolution round the ring, a
minute portion of grease to the extent required being given off to the traveller
every time it passes the lubricating point. One application of grease thereby lasts
several days instead of being required in some cases at every time of doffing the
bobbins and accumulation of fly is prevented.
The invention will be best understood by reference to the accompanying drawings
in which
Fig. 1 is a cross section through a double-edged flanged ring and Fig. 2 is a plan
of the same.
A is the ring, B the traveller and C the lubricating holes. The hole on the top
flange of the ring is more or less countersunk as at Cl according to the space
available the lower portion terminating in fine needle point hole under the flange
where the traveller has contact in its passage.
In the case of other forms of spinning and doubling rings the hole is simply so
drilled or formed as to issue at the point of contact of the traveller.
The hole or holes are filled with suitable grease, and every time the traveller in
revolving passes the hole it draws off a minute portion of grease which keeps the
rings in proper working condition. The suction of the traveller acting with the
temperature of the room and of the ring generated by friction causing the grease
to flow with extreme slowness.
The holes can be made in different positions on the ring so as to lubricate more
than one point of contact of the traveller as shown in Fig. 1 in which is shown
one hole on each side of the ring, one at the left of the drawing to lubricate the
exact corner of the underneath portion of the flange and the other to lubricate the
middle of flange.
The amount of grease supplied can be regulated by the size of the boles; in
spinning rings a hole that will admit a fine needle is sufficient, but it must not be
large enough to allow of traveller catching in it.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. The lubrication of spinning and doubling rings by means of fine holes sub-
