One object of my present invention is to pro

And still another object of my invention is
to provide a novel means for lubricating parts of

or frusto-conical form, and the top wall of said
storage chamber is formed by a roof 0 preferably
of substantially cone shape, that is connected by
herein illustrated, on account of the fact that
it is easy to build; it is easy to install; it keeps
the cables, the cable grooves in the pulleys, and
the bearings for the pulleys in a properly lubri
cated condition; it automatically supplies a lu
bricating medium to the stu?ing boxes for the
cables; and it will remain in an operative condi
tion for a long period of time, without requiring
replenishing of the lubricating medium.

which is sealed by the liquid lubricating medium

provided adjacent its lower end with a laterally

of the reservoir 5, and which, if desired, may be

The pulleys 3, of which there may be any pre
ferred number, are herein illustrated as con
shown in Figure 3, so as to serve as an efficient
rain shield for'the joint between the receptacle

The bottom portion of the re

stantially cone-shaped part I2, having an open
storage chamber, through a pipe 4 at the upper
sisting of four pulleys, and are preferably ar
ranged in individual housings F mounted on or
attached to the roof C in such a way that the load
end of chamber, the piston B can move down
wardly into close proximity to the base I of the
apparatus, and when gases or air are withdrawn
from the storage chamber to purge or empty the
same, the piston B can move upwardly into close
or intimate relationship with the roof C, as shown
in bro-ken lines in Figure 1. In order to provide
access to the center tubular member D, said mem
ber is provided at its upper end with a manhole
2I, equipped with a loose, removable cover, and
provided at its lower end with a manhole 22 that
is preferably open to the atmosphere.
Preferably, the pulley housings F are of such
construction and are combined with the roof C in
such a way that they constitute liquid sealed
passages, through which the cables 2 travel while
passing from the cable openings in the top wall of
the storage chamber to the cable openings in the
.top wall of the tubular counterweight housing D.
In order to prevent gases from passing from the
storage chamber X into the pulley housings F,
and thence escaping into the counterweight hous
ing D, I provide each of the pulley housings with
stuffing boxes I, located at the points where the
cables 2 enter and leave the pulley housing. I
also prefer to construct each pulley housing so
that the parts associated with same, which are
subjected to wear, abrasion or friction, are kept
in a thoroughly lubricated condition. Obviously,
‘the pulley housings can be constructed in various

A washer or wiper I3, preferably
constructed of felt, is attached to the upper end
portion of the stuffing box I, in any suitable way,
as, for example, by a clamping wire I4 that holds
it in overlapping relationship with the .cone
shaped portion I2 of the stuffing box, so as to
snugly embrace the cable, and thus'prevent air
or gases from passing in either direction through
the joint between the cable and the felt portion
I3 of the stu?ing box that embraces the cable.

moves excess oil on the surface of the cable. The
oil removed from the cable or stripped off of same
by the washer I3, drains down the inner side of
the cone-shaped portion I2 of the stu?ing box,
into the annular space between the tubular body
portion II of the stu?ing box and a sleeve I5 ar
ranged inside of said body portion 1 I, as shown
in Figure 6, there being one or more discharge
ports I6 at the lower end of’ the annular space
between the parts II and I5, through which the
collected or recovered oil can return to the reser

that is engaged by the cable 2, is kept properly lu

saturated with the oil y in the reservoir 5 and
then apply such oil to the cable 2 or to the cable
groove in the pulley 3. Thus, as shown in the
drawings, the pulley 3 is provided at its periph
ways, without departing from the spirit of my _
