E. MOSSBACH in BORNA near LEIPZIG. Liquid lifting device using outgoing vapors.

Patented in the German Empire on July 7, 1877.

About the vapors consumed by expansion steam engines, the so-called return or Free vapors, which up to now have only been used to give partial heat in preheaters and were used for heating, but the power can still be used through condensation do without, however, a noticeable counter-pressure on the effect during to cause their expansion serves the

Liquid lifting device (free steam pump).

In this self-controlling pump, the steam is introduced through a collecting space JY, in which a flap i moves, which can be pressed more or less against the outlet opening of the steam against the collecting space by two arms with small adjusting weights. The purpose of this flap is to make it easier to fill the lifting device with steam. The actual steam supply pipe B forks at C to supply an upper and lower lifting device D and E with steam. In one, as in the other, the steam first enters a housing M ₁ which is connected to two standing cylinders O and P by means of two elbow tubes L and L ¹ . The latter are provided with two outlet openings R and R ' and are connected to a common suction pipe 6 ¹ by the double elbow pipe T. In the housing M , a flap α is moved back and forth between approximately half a right angle, namely on an axis bc by the double lever de. This again gets its oscillating movement through the doors H and K, with which it is connected by means of two chains / and g of round rings. Above the mouths of the elbow tube T, there are valves m made of strong rubber disks in the cylinders, which open upwards. Finally, small air valves η and / are attached to the upper part of the cylinder.

■ The work done by the apparatus will be easy to explain from now on. When starting giefst one of the same small amount of water on the floor "of the cylinder (by. The doors), and gives the lever de an oblique position, fills whereby a cylinder with steam by the door opens (balanciren both doors' with each other). it works now the lever, then the cylinder is α upwardly through the cover and closed at the bottom by the door, and the condensation of the vapor occurs (accelerated by the air valve), and is in the intake manifold, first the air and then attracting to be lifted liquid which can enter the cylinder through the upwardly opening rubber valve m , but cannot recede again. The liquid will reach a certain height in the cylinder, but then, when the condensation is over, it will open the door again by its own pressure and flow out During this stroke the other cylinder has been filled with steam with the door open open the door and close the door of the other cylinder. Condensation now occurs in this, and the same process is repeated, so that an almost constant current will arise.

Of course, the flap α must close well on its seats and move freely in the housing M without being pushed back and forth, which is achieved by adjusting rings on the ends of its axis on the outer housing. Likewise, the doors with the edges of the spouts must be hermetically sealed, and therefore lined with lids.

The fact that there is no considerable counter-pressure on the machine working with expansion in this apparatus also shows that the vapors are drawn out of the collecting space by the sinking of the liquid in the cylinders (i.e. through a vacuum), although the low natural pressure in this spaces (increased by the flap i ), contributes. A tight closure of the valve axis bc, for example by means of stuffing boxes, is therefore not required.

The simple construction of the apparatus with only one valve in each cylinder is guaranteed the advantage that this, if it shifts, can be immediately put by hand (through the doors) can clean again without having to loosen any screw connection.

The apparatus does not need to be set up in the immediate vicinity of the collecting area and

of the preheater, but can also be done remotely, in which case you just run through the steam supply pipes, cladding with poor heat conductors from premature Has to protect condensation.

It goes without saying that each pump set can only be used up to a delivery head corresponding to the pressure of the atmospheric air, i.e. not above approx. 9 m. At higher altitudes, if there are enough vapors at all, several sets and at the same time a corresponding vapor distribution, e.g. B. be set up by cone valves Z so that each pump set draws equal amounts of water.

Since, however, there is a lot in the case of most industrial plants with steam operation lower heads are involved, z. B. at sugar factories, breweries, distilleries etc. to raise of liquids in the first and second floors, where the apparatus is just as good as in the Ground floor can be set up in quarries and open pit mines for drainage or at any other steam company for the procurement of drinking water from · wells or for irrigation of gardens and fields from deeper ponds etc., so the ' number of two sentences are seldom necessary. However, there are special operating costs with this Apparatus completely gone.
