Improvements in the Method of Mounting Tension Pullies,
Applicable to Spinning and Analogous Machines.
I, FRED UNWIN, of 154 Chaussee de Mons., Brussells, in the Kingdom of Belgium,
Mill Manager, do hereby declare the nature of this invention to be as follows:-
This invention relates to certain improvements in the manner of mounting tension
pullies applicable to spinning and analogous machines, and has for its object, the pro-
vision of ineans whereby the journals of the same are adjustable, self lubricating and
so arranged that the oil is not wasted and absorbed by the loose fibre falling on to the
journals, as is now the case when mounted in the usual manner.
I accomplish my object by forming a cup on an ordinary tension pulley supporting
bar, and covering the said cup with a lid having flanges that project for some distance
into the interior of the same. Through each side flange of the said cup, I bore a
hole, recessing the same, and making them conical, each hole converging towards the
interior of the cup, and through the said conical holes I place a spindle having a
conical head, the other end being parallel and screwed for some distance for the recep-
tion of the tension pulley, which is screwed thereon until its conical boss on one side
rests in the conical hole in cup flange; the pulley being then locked in its adjustable
position by screwing a nut on the said spindle against the outer boss.
On the spindle inside the cup I place a disc or finger, which revolves or dips in oil
every revolution, thereby constantly lubricating the journals; any oil that may escape
through the conical bearings to the outside being collected by a recess on each side,
from which is a channel to the interior.

I, FRED UNWIN, of 154, Chaussee-de-Nous, Brussells, in the Kingdom of Belgium,
Mill Manager, 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 certain improvements in the manner of mounting tension
pullies applicable to spinning and analogous machines, and has for its object the pro-
vision of means whereby the journals of the same are adjustable, self lubricating, and
so arranged that the oil is not wasted and absorbed by the loose fibre falling on to the
journals as is now the case when mounted in the usual manner: and consists in form-
ing a cup on an ordinary tension pulley supporting bar, and covering the said cup
with a lid. Through each side flange of the said cup I bore a hole, recessing the
same and making them conical: on the spindle inside the cup I place a disc or finger
which revolves or dips in the oil every revolution thereby agitating the oil in the cup
that the journals are constantly lubricated.
In order that my invention may be more fully understood I will further describe
the same by making reference to the accompanying sheet of drawings in which
Fig. 1. represents a plan of a tension pulley mounted according to my improved
method, the lid being removed from the cup.
Fig. 2. is a section through line X. X.
Fig. 3. is a section through line Z. Z., and
Fig. 4. shews a method of mounting a pulley between two bearings.
On the ordinary tension pulley supporting bar A. having a pulley on one side
thereof, I form a cup B. and cover the same with a lid C. having flanges CV which
project for some distance into the interior of the cup B., the said flanges C¹ preventing
the oil from escaping between the cup and lid. Through each side flange D. of the
cup B. I bore a conical hole, recessing the same at E., each hole converging towards
the interior of the cup B. and through the said conical holes I place a spindle F.
having a conical head F¹ of the same contour as the hole in corresponding flange D.
of the cup B.; the opposite end F2 of the spindle F. I form parallel and screwed for
some distance in order to receive the tension pulley G. which is screwed thereon until
the conical boss H. of pulley rests in the conical hole formed in the corresponding
flange D. of said cup; the pulley G. is then locked in its adjusted position by screwing
the nut J. on to the end F of spindle F.
On to the spindle F. inside the cup B. I mount a disc or finger K. which on
revolving with the spindle, dips into the oil L. contained in the cup B. thereby agitating
and distributing oil within the cup, that the journals are constantly lubricated, and
any oil that may escape through the conical bearings to the outside is collected by the
respective recesses E. on each side, from each of which, it is conveyed by a channel M.
back to the interior of the cup C.

page_text: A tension pulley G. may be mounted between two bearings as illustrated by Fig. 4.
and may be accomplished in the following manner.
The spindle F. is screwed in the centre for the reception of the tension pulley G.
which is screwed thereon, the ends F and F being reduced in diameter and pre-
pared to receive the conical bearing collars N. N. which are secured in their position
by being screwed on to the said spindle ends, and held in the adjusted position by the
respective nuts J. the bearing being constantly lubricated and the oil conveyed back
to the cups C. by the channels M. in the manner as before described.
It will be easily perceived, that by screwing the boss H. of the tension pulley G.
into the conical bearing so as to work freely therein, or in case of an arrangement as
shown by Fig. 4. when the conical bearing collars are screwed on the spindle so as to
be set to the required position, they are securely locked on the spindle F. by means of
the nuts J.; and when the bearings are worn or become slack, they can be easily
adjusted by the regulation of the pulley G. or bearing collars N. N. as before
described.
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 :-
The method of mounting tension pullies in journals having adjustable conical bear-.
ings, the said bearings being automatically lubricated by a disc or finger and all
arranged substantially in the manner as shown and herein before described.
