This invention relates to gas holders and more particularly to those of the water sealedsingle lift type. This invention WBSVOII nally described in my previously filed app cation Ser. No. 93,113 filed March 8th, 1926,

of which this is a full continuation.

The type of gas holder in most common use consists of a tank or water reservoir in WhlCh one or more lifts are constructed 10 such a manner that as the gas is introduced into the holder the lift is elevated and the gas is prevented from escaping by means of the li uid seal at the lower edge of the lift.

11 a single lift holder, the lift comprises a 15 single inverted bell which is open at the bottom or liquid-sealed end and is closed at the top by a crown curved to the form of a section of a sphere and made gas-tight throughout. As gas is introduced and withdrawn from the holder, this bell or lift rises and falls and is supported by the gas pressure within the holder; the bottom of the lift being sealed against gas escape by the liquid seal provided by the water tank or liquid reservoir.

In order to confine the lift-to a vertical movementalone and prevent tipping, it is customary to provide a guide-frame or heavy structural steel frame work which usually is attached to the side of the tank and which serves to hold'the lift in a vertical position throughoutits travel. The lift is provided with suitable guide-rollers held by oosenecks attached to the crown of the li and which engage guide-rails attached to the guide-frame, or as in the usual practice engage a vertical memberof'the guide-frame itself. Similar rollers are attached to the lower edge of the lift and en ge guide-rails installed against the ins de wall of the tank. The guide-frame must be'sufliciently strong and r1gid to prevent any normal tendency of the lift to tip out of-line when in an elevated position and,-'furthermore, must be strong enough to withstand all wind strains against both itself and the lift which it guides. The

height of the guide-frame is determined by the depth of the lift and its vertical travel.

The'primary object of the present invention is to provide a means whereby the vertically movable lift ma be held in proper alignment without em l oying the usual heavy and expensive guideame.

Another object of the invention is to provide a guiding means which will permit a lift to be installed in practically any type of'tank without requiring special foundation work or other alterations for accommodating a s ecial guide-frame.

other object of the invention is to provide a means for guiding the lift of a holder, 60 which may be contained within the'holder and protected from climatic conditions involving atmospheric oxidation and corrosive reactions. 7

Another object of the invention is to rovide a means for guiding agas holder, w ich rmit of quick and easy alignment of the 11ft in the event of foundation settlement and tank wa age. Further ob ects of the invention are to'provide a guiding means for a gas holder that is simple and inexpensive to install; is easy to keep in proper adjustment and repair; and makes the holder unit more attractive in appearance. i 1

With these and other objects in view the invention consists in the improved method of constructing a gas holder as hereinafter illustrated and claimed.

, Fig. 1 is 'a plan view with arts in section of a single-lift gas holder em odying a pre ferred form of the invention, and

Fig. 2 is a vertical sectional view. of the holder shown in Fig. 1'.

The means or mechanism for guiding a gas holder in the present invention has been illustrated as applied to the common type holder consisting of hollow bell, or lift, mounted in a tank of water. The lift 10 moves vertically up and down in a tank 12,

v of the tank.

escape of gas by a body of water in the tank :3, the level of the water being indicated at As the gas moves into and out of the lift, the lift rises and falls, the Weight of the lift being supported by the body of gas within. It W111 be apparent therefore, that the lift must be accurately guided in order that it may operate freely and effectively. Spacing rollers 19 (Fig. 1) mounted on the inner rim of tank 12 between the tank and the lift serve to hold the outer periphery of the lift in properly spaced relation to the inner periphery The guiding means of the present invention consists of a series of flexible cables, ropes, chains or other flexible members which are mounted within the tank and lift and attached to the tank and lift so that they guide the lift and constrain it to move in a vertical path. To accomplish this cables '20 are arranged in pairs around the periphery of the lift and preferably each pair is mounted to extend across the lift diametrically. Each pair of cables is the same and each pair is mounted in the tank and lift in the same way so that only one pair of cables will be described. One cable of a pair is attached to a hanger 22 near the rim of the tank then passes down the tank under a pulley 24 then. up and over a pulley 26 mounted under the crown of the lift, then across the lift and over a pulley 28 on the opposite side of the lift from the pulley 26, then down and under a pulley 30 1 mounted on'the lower edge of the lift vertically below the pulley 28, then up to a bracket 32 mounted on the rim of the tank at a position substantially diametrically opposite from the hanger 22. At the point where the cable above described emerges from the water to be attached to the bracket 32 the cable may be in the form of a chain as shown, which will better withstand the corrosive action that occurs at the waters surface. The connection of the cable with the bracket 32 consists of a a bolt 34 passing through a heavy compression s ring 36 which acts to hold the cable taut.

he other cable of the pair is mounted in the tank and liftin the reverse position from the above described cable and moves parallel to it. For example, the other cable of the pair has one end attached to a hanger 23 fixed to the rim of the tank adjacent the bracket 32,

then it passes down under a pulley 38 in the bottom of the tank, then up over a pulley 40 adjacent the pulley 28, then over a pulley 42 adjacent'the pulley 26, then down under a pulley 44 mounted on the bottom of the lift and then up to a bracket 46, to which it is connected by bolt 34.

In the drawing only two pairs of cables have been illustrated but it is apparent that any desired number of maybe used and the pairs would preferably be uniformly distributed around the inner periphery of the lift. It is not necessary that the cables be positioned on the diameter of the lift as illustrated in the drawing. When the lift moves up and down the ends of the cables remain fixed and the cable moves on the pulleys 26, 28, 30, 40, 42 and 44 to adjust them for the (hfferent positions of the lift. The cables constrain the wall of the lift to move in a vertical plane. The. side pressure of the wind against the side of the lift. is effectively resisted by the arrangement of the cables in passing under the pulley attached to the lower edge of the lift.

The pulleys 24 and 38 act only as guides for the cables since the cables do not move in these pulleys as the lift moves up and down. These pulleys however are useful inchanging,

inspecting or repairing cables. Forexample,

a. new cable may be attached to an old guide cable and then pulled into the position occupied by the old guide cable while the old guide cable is being removed. This new cable may then be used for replacing the guide cable or may be withdrawn again if the old cable is found to be in good condition. This operation may be carried on'without entering the tank or lift.

With" the above described apparatus the guide cables are housed entirely within the tank and lift and are thus protected from at- 1.
