V * 217787 - CLASS 26 b. GROUP

Patented in the German Empire on June 2, 1908.

The general spread of acetylene gas generators on ships is mainly due the great risk of explosion in the way associated with the apparatus of the present invention is eliminated. The refilling of carbide and water in the gas chamber as well as the discharge the consumed carbide and water takes place automatically through the free inflow and outflow of the fairway into the carburetor room.

ίο In addition, one is always with the fairway related relief line provided through which when the gas line is shut off or excessive gas generation, the gas can escape unhindered into the fairway.

The drawing shows the new acetylene gas generator installed in the hull of a ship vertical section shown ..

The developer installed in the ship's hold Ä , • winder comprises a container B made of strong sheet metal, which is provided in its lower part with a bottom B ¹ inclined to a waterway tap B ³ . In the upper part of the container there is a chamber C ^{provided with a funnel-shaped bottom C 1} , which is intended to receive the carbide which is introduced through an opening usually closed by a cover C ^2. The outlet opening is closed in a known manner by swinging flaps D, D , on which arms D ¹ , D ¹ sit, which are articulated by arms D ³ , D ³ with an annular float D ² in the gasification chamber E. The gas flows through a line E ¹ connected to the chamber E and through a pipe E ² branching off from this into a gas container F, which also serves as a pressure regulator. The gas container consists in a known manner of a container filled with water and a bell F ¹ located therein. The latter 'is connected at its uppermost point by a joint F ² with an arm Zs ⁴ , by means of which a shut-off valve E ³ mounted in the gas line E ² is closed or opened when the bell F ^{1 rises and falls.} The gas line E ¹ is expediently extended upwards so far that its upper curvature is always above the top line of the fairway. At this point the line E ^{1 is} connected to a relief line ZT ⁵ . The latter is connected to an elbow pipe B ² containing the tap B ³ so that the gas entering the line E ⁵ can escape into the fairway, which prevents any risk of an explosion inside the ship, since the tap B ^{3 is} always open, except when a refill of carbide takes place. In order to be able to lower the water level in the gasification chamber E when the tap B ^{3 is} closed when carbide is being filled in, the container B is provided with a drain tap H. The float D ² only comes into its own when the flaps D are opened at a certain water level. So-

as soon as the water level in chamber E sinks below this level, the swimmer remains hanging on arms D ³ , D ³ , the flaps D, D being tightly closed by his weight. ...... · ..,. ,,

The apparatus works in the following way:
As soon as the carbide chamber C is filled and the filling opening is closed by the cover C ² , the water tap B ^{3 is} opened so that

ίο the fairway can enter the chamber E from the outside through the knee tube B ^2. The float Z) ² will slowly go up and the flaps D, D open as soon as carbide moves from the inclined walls C ^{1 of} the funnel C onto a table located in the gas chamber E , attached to the inclined floor B ¹ and under water / slips up. The rise of the water in chamber E continues until the gas generated in the same reaches a pressure which is equal to the pressure of the water penetrating from the outside. 'The rises. Gas pressure then continues, so the water is gradually pushed out of the chamber E until the float D ² remains hanging on the arms D ^z , D ³ and closes the flaps D due to its weight. As soon as the pressure of the gas drops, new water will penetrate into the chamber E and drive the float up again, so that the flaps D open and carbide can enter the gas chamber.

The gas generated flows through the line E ¹ , E * into the container F, from which it is fed through the pipe G to the point of use. If the gas exceeds the required operating voltage, the bell F ^{1 of} the container F is driven upwards, whereby the lever ZJ ^{4 connected} to it closes the tap E ³ and prevents the container F from being filled again. The gas will now flow out through the relief line E ^{5 connected to the upper end of the line E 1} and the elbow pipe B ² into the fairway, where it is harmless.

As a result of the inclined bottom B ¹ in container B , the used carbide is automatically transported to the outside every time the water flows out of the chamber Έ. The alternating inflow and outflow of the fairway causes both a supply of carbide and water to the generator that is adapted to the respective gas generator and a continuous cleaning of the developer by removing the consumed carbide and water.

At the confluence of the line E ² in the container F , a cap K is attached to the tube E ² , which is immersed in the water in the container F and thus prevents the gas from flowing back from the container into the developer.

Claims (2)

Patent Claims: 1. Acetylene gas generator for watercraft, in which the container containing the carburetor chamber is in communication with the fairway, characterized in that the elbow pipe (B ² ) connecting the carburetor chamber (E) with the fairway and can be shut off by a tap (B ³ J ) is used the valve (B ³⁾ and the mouth. of the tube (B ²⁾ in the fairway a to the gas line (e ¹⁾ connected to the discharge pipe (e ^B) is connected, such that when the shut-off of the gas line, the. gas (e ¹⁾ can flow out of the carburetor chamber (E) into the fairway, thereby avoiding the risk of an explosion. 2. acetylene gas generator according to claim 1, characterized in that the relief pipe (E ⁵ ) is connected to a point of the gas line (E ¹ ) projecting above the top waterline of the fairway, 1 sheet of drawings.
