LADDER DEVICE FOR SCENDING. GAS

` neck /nventan' Patented july 5, 1932 UNITED YSTATES PATENT OFFICE FRIEDRICH EINBECK, OF DORTMUND, GERMANY, ASSIGNOR TO THE FIRM AUG. KLNNE,
OF DORTMUND, GERMANY LADDER DEVICE FOR ASCENDING- GAS CONTAINERS Application led December 20, 1928, Serial No. 327,440, and in Germany January 5, 1928.
The subject of the present invention forms a mechanism for descending into, and ascending from, gas containers, particularly waterless gas containers, in which the closeness of the disc against the container wall must be inspected from time to time,y in order to discover any leakages. The air space above the disc inside the container must therefore be accessible at all times and at all positions of the disc. For the present purpose in accordance with the scope of the invention an articulated ladder is arranged, which at its lower end is secured to the disc, passes overa guide wheel on the cover and is held taut by means of counterweights, which must equal not only the weight of the articulated ladderl alone, but also the maximum admissible loads of the articulated ladder. Preferably this articulated ladder is made in duplicate, the two parts being arranged opposite to each other, the two articulated ladders being supported by means of reciprocal elements engaging one within the other, so that a ladder shaft is formed, which is made up of the two oppositely lying articulated ladders and the side lelements belonging thereto.
The invention is shown on the accompanying drawing.
Fig. 1 shows the complete arrangement with two articulated ladders;
Figs. 2 and 3 show a part of the ladders on a larger scale;
Fig. 4 is a fragmentary section on a larger scale of a rotary connection at the lower ends of the ladders; and
Figs. 5 and 6 are a side elevation and a top plan view of Fig. 4 with some parts removed.
The mechanism consists of an articulated ladder a, shown in side elevation in Figs. l and 2, and in front elevation in Fig. 3. This articulated ladder is fastened at its ower end to the movable disc b by means of a foot fastening k. The articulated ladder a is passed over a guide wheel d, which is secured Vto the cover c of the container. The cover c carries an' entrance turret T, through which the articulated ladder a can be conveniently climbed. The articulated ladder w is held taut by a counterweight e. Preferably the 50 articulated ladder a is made in duplicate. In
this case the articulated ladders have lateral hooks f, which engage with each other from above alternately from left to right, so that the load of the ascending or descending persons is always transmitted equally to both counterweights. At the same time the distance one from the other of the individual articulated ladders is determined by these hooks f and a reciprocal stiffening is achieved, so that the mounting of the articulated ladders is simplified. The distance of the individual chain ladders from each other and the length of the ladder rungs g correspond to the usual measurements, so that comfortable mounting is possible. Through the reciprocal arrangement of two articulated ladders and the lateral hooks f a ladder shaft is formed, which possesses rungs for ascending and descending on two oppositely lying sides, and in which hooks f arranged on the other two sides give protection against falling. The foot fastening L is rotatably secured to the disc 5. This arrangement is best shown in Figs.
4 to 6 wherein the foot-fastening L is movably connected with the disc b through the intermediary of hinge elements Z and swivelk.
I claim Y Ladder device for ascending gas containers with an ascending and descending disc, compri-sing two ladders with lateral inter-engaging elements, a member connecting said ladders lat one end, a universal joint connecting said member to the movable disc adapted to articulate each of the two ladders, guide rollers secured to the cover o-f the container over which rollers the other ends of the link ladders pass, and counter-weights each connected to the free end of each ladder and holding taut the link ladders.
In testimony whereof I have affixed my 90 signature.
