An Improved Apparatus for the Lubrication of Revolving Parts of
Machinery Pullies and the like.
We, GEORGE BEN GOODFELLOW of Hyde in the County of Chester Engineer,
and EDWIN ARTHUR PICKUP of 208 Mottram Road Hyde as aforesaid Engineer
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:-
Our invention relates to the lubrication of rotating parts of machinery more
especially to those parts which have hitherto been difficult to keep continuously
lubricated. It has for its object the provision of means whereby a constant
supply of oil or lubricant to the frictional surfaces is maintained by creating a
circulatory movement of the oil.
In order that our said invention may be better understood and more easily
carried into effect we have hereunto appended a sheet of drawings wherein
Fig. 1 is a partially sectional view of the application of our said invention to
guide or idle pulleys and
Fig. 2 is a sectional view through the line X Y in Fig. 1.
.
In carrying our said invention into effect we form on the side of the pulley P
or otherwise attach thereto a disc, plate or vanes A, hereinafter called the disc.
We also fix to the framing on each side of the pulley light cylindrical cases CH
made of iron brass or other suitable material which are formed as shown with
flanged ends to enable them to be attached to some fixed part of the mechanism.
The inner faces are turned up as at C¹ H' for a purpose hereinafter described.
The disc A rotates within one of the said cases C. Within the case C and
extending round its upper portion a trough D is fixed this being of the section
shown. A connection is formed by the opening E between the trough D and the
oil duct F which is bored up the centre of the spindle or arbor K
upon which
the pulley revolves. The duct is closed at the outer end of K by the screw L
which is also utilised to hold the pulley and case H in position. A connection G
is established between the duct and the interior of the pulley P so that the
oil in F can freely find its way to the inner surface of the pulley eye.
The two
cases C H are connected by a pipe J at the underside. Although this forms a
suitable arrangement when our invention is applied as shown in the drawings,
we may construct both cases like C with the trough D or we may use one case
only.
The operation of our invention is as follows. The lower parts of the case C
contains sufficient oil to enable the edge of the disc A in its rotation to be
immersed in it. The oil is flung by centrifugal action upon the upper portion of
the case and collects in the trough D from which it flows into the oil duct F thus
lubricating the inner surfaces of the pulley and the outer surface of the pin or
arbor. The oil which escapes at the ends of the pulley bosses drips into the
cases C H and is again utilised for lubrication. That which collects in the case H
flows into C by means of the pipe J. The curved flanges C'H' prevent the
leakage of any oil from the cases as it drips, conveying it again into the reservoirs.
In this way there is a constant flow of oil through the eyes of the pullies in
addition to which the cases C H act as oil catchers or savers, and prevent the oil
being scattered about the floor.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is.
1. The combination and arrangement of parts whereby a constant circulation
of oil is maintained in the bearings of rotating parts of machinery in the manner
and for the purpose as herein described and illustrated.
2. The combination with the rotating parts of machinery of a disc and an oil
case or cases all constructed and applied for the purpose and in the manner as
.herein described and illustrated.
