One object of my present invention is to pro

pass through the wall of the storage chamber.
And still another object of my invention is
to provide a novel means for lubricating parts of

or to wear excessively, if they are not'kept in a
properly lubricated condition. Other objects and

Arranging the pulley housing or housings on
the exterior of the storage chamber, preferably
on the top side of the roof, as previously ex;

stituting the two portions A and A’, previously
referred to, it is preferable to form ventilating
openings Ia in the base or foundation I of the
apparatus. The bottom wall of the storage cham

or piston B, preferably of substantially cone shape
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.
As shown in Figures 3 to 6 of the drawings, each
a gas-tight joint to the top edge of the side wall 10

apparatus, and projects upwardly through a
pulley-3 is completely housed by a removable
cover 6 that ?ts loosely in the receptacle 5, and
which is sealed by the liquid lubricating medium
11 in said receptacle. Usually, the cover 6 will be
provided adjacent its lower end with a laterally
travel over wheels or pulleys 3 located above the 20 projecting flange ‘I that rests upon the top‘ edge
of the reservoir 5, and which, if desired, may be

a center support for the roof C and also act vas

pended from cables, chains, or equivalent devices
2, that lead upwardly from the piston B and
gas-tight joint to the roof C.
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
2.5 5 and cover 6.
The bottom portion of the re
ceptacle 5 is permanently attached to the roof
C of the apparatus, preferably by welding, and
said receptacle 5 is so arranged with relation to
the counterweight housing D, that the central

through which said tubular member D extends,
shown in Figure 6, and comprises a tubular outer

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.
55 In addition to sealing the cable 2, the washer'I3

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
bricated by members on the pulley 3 that become
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 _
invention, but I prefer to use the construction 75 ery with two ring-shaped members I'I, con
