Application January 27, 1944, Serial No. 519,957 12 Claims. (01. 48—178) 1 2 This invention relates to ?uid storage appara container that also serves as a housing for the tus of the general type or kind disclosed in my weight of the counterweighting mechanism, and U. S. ‘Patents Nos. 2,102,299, dated December 14, 1937, and 2,337,010, dated December 14, 71943, and in my pending application Serial No. 363,835, a housing or housings for the pulley or pulleys of ?led November 4, 1940. V ' v One object of my present invention is to pro vide an apparatus of the general type or kind mentioned, whose co-acting parts are constructed the counterweighting mechanism, mounted on the top side of said roof at such a point that the load exerted‘ on said pulley or pulleys is borne by or transmitted directly to the tubular roof support and counterweight housing. The said ‘ combined roof support and counterweight hous or arranged in a novel manner, that decreases the 10 mg is preferably arranged at the center of the “dead space” of the apparatus when the storage chamber is empty. » Another object is tosimplify the construction, reduce the cost, and facilitate the inspection and repair of such an apparatus. Another object is to provide a novel means container and is attached to the roof in such a way. that theinterior of said combined roof sup port and weight housing is separated from the storage space or’ chamber of the apparatus. I also prefer to provide means for preventing gases from escaping from the storage chamber into the for sealing the cables, chains or equivalent de pulley housing or housings, and thence, ?nding vices of the counterweighting mechanism for the its way into the vertically-disposed, tubular member at the center of the container which piston, at the point or points where said cables 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 the counterweighting mechanism of the appara tus, that are apt to create an objectionable noise, or to wear excessively, if they are not'kept in a properly lubricated condition. Other objects and desirable features of my invention will be here houses the counterweight and also serves, as a support for the roof of the container. Arranging the pulley housing or housings on the exterior of the storage chamber, preferably on the top side of the roof, as previously ex; , plained, reduces the “dead space” when the storage chamber is empty, and makes it possible to design or construct the piston and‘the top wall inafter pointed out. I of the storage chamber so that they are in nested relationship, or in approximately touching con ‘ Figure 1 of the drawings is a vertical trans verse sectional view of a gas holder constructed 30 tact with each other, when the piston is at the end‘ of its upward stroke, or, in other words, in accordance with my present invention. Figure 2 is a fragmentary top plan view of said apparatus. Figure 3 is an enlarged vertical sectional view of one of the pulley housings, said view being when the apparatus is empty. In the particular form of my invention herein‘ illustrated, a reduc tion in the “dead space” is also obtained by sepa rating or cutting off ' the counterweight housing from the storage chamber and constructing the pulley housing ,or housings so that gases cannot Figure 4 is a horizontal sectional view, taken circulate from the storage chamber into the pul on the line 4-4 of Figure 3. , ley housings and thence into the tubular roof Figure 5 is a sectional view, taken on the line 5-5 of Figure 3; and 40 supporting. member at' the center of the appara tus-that ‘serves as a housing, for the weight of the Figure 6 is a/vertical longitudinal-sectional View piston counterweighting mechanism. of one of the cable stu?ing boxes. In the accompanying drawings, which illus Brie?y described, my present invention con trate the preferred form of my invention, A sists of a ?uid storage apparatus, that comprises a container provided with a roof, 2. piston or 45 designates a verticallyedisposed, cylindrical, gas tight shell that forms the side wall of the gas equivalent member, that is adapted to move in storage space X of the apparatus, said shell A one direction so as to increase the volume of being sustained or supported in an elevated posi the storage chamber of the apparatus, and move tion in any suitable way, as, for example, by a in the opposite direction so as to reduce the continuation or extension A’ ofv the shell A, that volume of said storage chamber, a counter rests upon'a'ba'se' or" foundation I, as shown in I weighting mechanism for said piston comprising Figure 1. The extension or continuation A’ of a weight or weights, a cable, chain or equivalent the shell A ‘need not be‘ gas-tight. In instances device attached to the counterweight and to the where the side wall of the'apparatus is formed piston and arranged so as to travel over a pulley or wheel, a tubular support for the roof of the 55 by a continuous, vertically-disposed shell: con taken on the line 3-—3 of Figure 4., > 2,408,539 3 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 ber X is formed by a Vertically-movable member 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 4 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 of the pulley housings F comprises a receptacle shell A. A vertically-disposed, tubular member 5 that is adapted to serve as a reservoir for a D, preferably of cylindrical shape in cross sec body of lubricating medium 1/, in which the lower tion, is erected on the base I at the center of the‘ end portion of the pulley 3 is submerged. The 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 roof C of the apparatus, the upper end of the provided with a downwardly-projecting lip, as center tubular member D being connected by a center opening in the piston B, so as to serve as a center support for the roof C and also act vas a housing for a counterweight E that is sus-_ 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 imposed on said pulleys by the counterweight E, the cables 2, and the piston B, is borne by or 30 portion of the pulley housing is in approximately longitudinal alignment with the tubular side wall transmitted directly to the tubular roof support portion of the counterweight housing D, as shown and counterweight housing D. A flexible sealing in Figure 3. The axle or shaft 8, of the pulley 3 element G is attached to the peripheral edge of turns in bearings 9 carried by parallel supports the piston and to the lower end of the side wall It that project upwardly from the bottom of the A of the storage chamber, so as to seal the space '7" reservoir 5, and the stu?ing boxes I, previously or joint between said parts, and a similar ?exible referred to, are attached to the bottom of the sealing element H is attached to the central por reservoir 5 in alignment with the groove in the tion of the piston and to the center tubular mem pulley that receives the cable 2. Each of the ber D, so as to seal the opening in the piston, up stuffing boxes I is preferably of the construction through which said tubular member D extends, shown in Figure 6, and comprises a tubular outer said sealing elements being of such shape and portion I I, provided at its upper end with a sub dimensions, that when gases are admitted to the 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 ing or hole in same that serves as a guideway for 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 acts as a stripping device, which effectively re > the cable 2. 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 voir 5. The groove or surface in the'pulley 3 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 ‘ "$2,408,539 5 - , structed of felt-'01" other, suitable ¥_m'aterial, -~tha‘t are‘ retained in position tynampiag rings-is, gas ='-'s_terageispace,ias ipreviously}‘explained.
