THEODOR LÜBBECKE in ALTONA a. E.

Patented in the German Empire on August 13, 1912.

The present disinfection device consists of a larger, suitably mobile container a, which is tightly closed and only by a closable inlet cock b and a closable drain cock c, which are located at the bottom of the container, also by a closable in the ceiling of the container Outlet cock d and a likewise closable filling opening e

ίο can be opened and closed.

The container is cylindrical and contains a piston f. This piston is movable in the container a 'and is guided by the tube g. The latter is at the bottom with the inlet tap b and the pressurized water supply line h in connection and can be opened and closed by the tap b , while it opens up in the ceiling of the cylinder through a closable outlet tap i into a pipe k . The end of this tube k is connected to a hose / which ends in a jet mouthpiece with a double nozzle. The closable filling opening e in the ceiling of the cylinder is connected to a funnel m . The outlet cock d opens and closes the outlet from the cylinder a into an acid pipe n, the opening of which can be enlarged or reduced at the end by screw-on and replaceable nozzles with a smaller opening width 0.

In the cover of the cylinder there is also a movable bolt p which closes the outlet valve i when it rises.

A sieve q made of sheet copper with about 150 small holes is attached below the outlet tap d , so that solid impurities which could clog the nozzle 0 are held back.

A manometer »'is provided between the nozzle and the acid chamber to display the acid pressure.

The inlet tap b is set up in such a way that it offers two paths for the water in the pressure line. The water enters the piston guide tube g at the same time and through the two conduction paths s ¹ and s ² into the container α under the piston f.

In use, m through the hopper and the filling opening a disinfectant e, z. B. cresol sulfuric acid, 40 percent formalin solution, concentrated soda lye or the like. Filled into the container α above the flask f and thereby the flask is pushed down when the drain cock c opens and the inlet cock b and the outlet cock d are closed. If the entire container α above the piston f is filled with pure disinfectant solution and the tap of the filling opening β is closed again, but the outlet tap d is opened again, the connection between the container α and the pressurized water line h is established by opening the tap b.

The pressurized water from the water pipe then takes two routes.

Once it flows through the hollow piston

Core tube g upwards, and k through the opened outlet tap * in the tube and in the end of k screwed hose I. Simultaneously, the water pressure urges the bottom by two lateral openings of the inlet cock δ and the two conduction paths s ¹ and s ² among the Piston, pushes it up gradually and drives the disinfectant above the piston

ίο through the open tap d, pipe η and nozzle ο into the pipe k. At the exit point, the disinfectant mixes intimately with the pressurized water. At the end of the hose an atomizing nozzle can be attached, when using this the uniformity of the mixture of water and disinfectant is increased and the liquid is directed in the form of a fine, dust-like and mist-like spray against the surfaces to be disinfected.

This uninterrupted, continued mixing of the disinfectant and the pressurized water lasts until the entire disinfectant liquid is pressed out of the container α by the piston. Just before the piston reaches its highest position in the container, it presses against the sliding bolt j> protruding into the container and pushes it upwards. The bolt closes the movable lever of the outlet valve connected to it i.

The disinfection worker must now fill the device with the disinfectant again. For this purpose he closes the inlet cock δ and the outlet cock 'd, opens the drainage path c and pours the disinfectant liquid back into the cylinder a through the funnel m and the filling opening e.

The disinfectant content of the sprayed liquid can be adjusted by using can be controlled as required by nozzles of various widths.

Disinfection can be carried out with cold and hot pressurized water. at With hot disinfection, the disinfectant liquid to be filled into the cylinder is also warmed up.

Claims (4)

Patent Claims: 1. Method of spraying uniform mixtures of water and disinfectants in any strength, characterized in that the disinfectant by pressurized water from a Container is driven into a narrower tube equipped with interchangeable nozzles and when it emerges from this pressurized water is mixed with the same line, which is passed through a das the nozzles supporting surrounding pipe is passed. 2. Apparatus for performing the method according to claim i, consisting of a cylindrical container which has a guide tube to be connected to a pressurized water line for a movable sliding piston, three inlet openings for pressurized water that can be closed by a common tap, one under a hopper, closable in the middle Inlet opening for disinfectant, each containing a closable outlet opening for the disinfectant and the pressurized water used to lift the sliding piston, characterized by a sliding bolt (p) which, after the container (a) has been emptied, has a tap ( g) attached to the extension of the guide tube (g) i) closes to interrupt the water supply. 3. Apparatus according to claim 2, characterized by a three-way valve b arranged below the container (a) through which the pressurized water simultaneously to the guide tube (g) and through the lines (s ¹ and s ² ) in the lower part of the container (a) flows. 4. Apparatus according to claim 2, characterized in that a for the discharge of the disinfectant from the container (a) serving, with sieve plate (q), cock (d) and exchangeable nozzles (0) equipped narrow tube (s) inside another , is arranged as a mixing space for disinfectant and pressurized water serving pipe (k) . 1 sheet of drawings.
