Den Gegenstand der vorliegenden Erfindung bildet ein an einem Wasserablafshahn anzubringender Filtrirapparat, bei dem eine Ausschaltung der Filterschicht möglich ist, so dafs das Wasser, ohne filtrirt zu werden, durch den Apparat gehen kann. Der Apparat gestattet gleichzeitig eine leichte Reinigung des Filters, ohne dafs es nöthig ist, ihn zu zerlegen, und ein leichtes Auswechseln der Filterschichten. The subject of the present invention is one to be attached to a water drainage tap Filtration apparatus in which the filter layer can be switched off, so that the water can pass through the apparatus without being filtered. The apparatus permits at the same time easy cleaning of the filter without it being necessary to dismantle it, and easy replacement of the filter layers.

Auf der beiliegenden Zeichnung ist der Erfindungsgegenstand an einem Wasserhahn angebracht zur Darstellung gebracht, und zwar ist:The subject of the invention is shown in the accompanying drawing attached to a faucet shown, namely:

Fig. ι ein Querschnitt durch den Apparat, wobei die Theile sich in der zum Filtriren nöthigen Lage befinden,Fig. 1 is a cross-section through the apparatus, the parts being in the area for filtering necessary situation,

Fig. 2 ebenfalls ein Querschnitt, wobei jedoch das W^Tasser unfiltrirt durch den Apparat geht,Fig. 2 is also a cross-section, however, the W ater ^T unfiltrirt through the apparatus passes,

Fig. 3 eine Oberansicht des Filtrirapparates, besonders zur Verdeutlichung des Reinigungsmechanismus. Fig. 3 is a top view of the Filtrirapparates, especially to illustrate the cleaning mechanism.

Die den Apparat einschliefsende Hülse A ist mit einer Kappe α versehen, deren oberer, mit Schraubenwindungen versehener Ansatz a¹ zur Befestigung an dem Wasserrohr dient. Sämmtliche Theile sind dicht mit einander verbunden, um jede Möglichkeit des Leckens der filtrirenden Flüssigkeit auszuschliefsen. Die Durchbohrung a³ des Ansatzes a^l dient zur Zuführung der Flüssigkeit zu dem Innern des Filters. Am Boden des durch das Gehäuse A und die Kappe a¹ gebildeten Raumes ä¹ befindet sich eine ähnliche Kappe α⁴, die ebenfalls mit Schraubenwindungen zur Aufnahme des Ansatzstückes B versehen ist, das durch Schraubengang b² in der Kappe α* befestigt ist, und durch dessen Durchbohrung b das Wasserauslafsrohr b⁶ hindurchgesteckt ist. Das Ansatzstück B ist ferner mit einem Handrädchen b¹ versehen, um es in der Kappe α⁴ drehen zu können. Das Stück B ist ferner an seiner Einmündung in das Gehäuse A mit Kanälen b^s versehen, die den Durchtritt des unfiltrirten Wassers aus dem Gehäuse direct in die Abflufsöffnung b gestatfen. Ebenso sind ähnliche Oeffnungen bⁱ in dem Rohr B vorgesehen, durch die das filtrirte Wasser in das Ausflufsrohr b⁵ einfliefsen · kann. Die Oeffnung b³ wird durch das Ventil b^e geschlossen, das an B befestigt ist, dessen untere Fläche sich gegen das Ventillager a⁵ legt, wenn das Filter zum Filtriren eingerichtet ist, während beim Heraufschrauben des Ventils das unfiltrirte Wasser hindurchgeht. Das das Rohr B umgebende Filtermaterial C, welches zweckmäfsigerw.eise aus porösem Stein bestehen kann und von der Oeffnung c durchsetzt wird, ist derart angebracht, dafs diese Oeffnung leicht durch die Platte b¹ sich schliefsen läfst. The sleeve A enclosing the apparatus is provided with a cap α , the upper projection a ^{1 of} which is provided with screw turns for attachment to the water pipe. All the parts are tightly connected to one another, in order to exclude any possibility of leakage of the filtering liquid. The through hole a ^{3 of} the extension a ^l is used to supply the liquid to the interior of the filter. At the bottom of the space formed by the housing A and the cap a ¹ a ¹ is a similar cap α ⁴ , which is also provided with screw turns for receiving the extension piece B , which is fixed by screw thread b ² in the cap α *, and the water outlet pipe b ⁶ is inserted through the through hole b. The extension piece B is also provided with a handwheel b ¹ in order to be able to rotate it in the cap α ^4. The piece B is also provided at its confluence with the housing A with channels b ^s which allow the passage of the unfiltered water from the housing directly into the drain opening b . Similar openings b ^{i are also provided} in the pipe B , through which the filtered water can flow into the outflow pipe b ⁵ . The opening b ³ is closed by the valve b ^e attached to B , the lower surface of which rests against the valve bearing a ⁵ when the filter is set up for filtering, while the unfiltered water passes when the valve is screwed up. The filter material C surrounding the tube B , which can expediently consist of porous stone and is penetrated by the opening c , is attached in such a way that this opening can easily be closed by the plate b ¹ .

An der Innenfläche der Hülse A sind Abstreicher D durch Anlöthen oder auf andere Weise befestigt, deren federnde Enden sich gegen den Filtercylinder C legen und bei dessen Drehung vermittelst des Handrades b^l die Aufsenfläche des Filtercylinders durch Abkratzen von Unreinigkeiten befreien, wobei dann das durchfliefsende Wasser die entfernten Verunreinigungen fortführt. Wenn das Ventil b^% auf dem Ventillager α⁵ aufliegt, und die'Auslassöffnungen b'⁶ verschliefst, durchströmt das Wasser den Filtercylinder, die Oeffnung £⁴ und Scrapers D are attached to the inner surface of the sleeve A by soldering or in some other way, the resilient ends of which lie against the filter cylinder C and when it is turned, the handwheel b ^l removes impurities from the outer surface of the filter cylinder by scraping it off, with the water flowing through carries on the removed impurities. When the valve b ^% rests on the ^{valve bearing α 5} and the outlet openings b ' ^{6 are} closed, the water flows through the filter cylinder, the opening £ ⁴ and

Claims

the drain pipe b ⁵ . If the handwheel b ¹ is now turned in such a way that the pipe B rises, the opening b ³ is also opened again, with the plate V finally resting against the cap α and closing the inflow opening α ^{3 of} the water.

If the filter material is too worn out by the action of the scraper D, the filter cylinder can easily be exchanged for a new one after removing the cap α and unscrewing the tube B. In the position illustrated in FIG. 2, the opening b ^{s is} open, on the other hand the inlet openings α are not yet completely closed, so that the water can flow out of the pipe B unfiltered around the cylinder C through the opening b ³ . With this filter it is therefore possible to obtain both filtered and unfiltered water and to regulate or shut off the flow of liquid as desired.

Patent claims:

i. Filtrirapparat, characterized in that a closure plate (b ⁷ ) on its surface and an annular valve (b ^s j) carrying an annular filter body (C) made of any material is displaceable in the height direction inside a housing in such a way on its lower surface that when the filter body is in its lowest position, the valve rests against the housing and the water is forced to flow through the filter layer into a tube (b ^& ) ^{located inside the filter body and provided with passage openings (^ '4} _/ j), while lifting of the filter body (C) the valve is lifted from its base so that the water around the filter is filtered off, flows outwards and, when the filter body is in the highest position, the water inlet is completely closed by the closing plate (b ⁷ ) of the filter, for the purpose to be able to turn the filter on and off at will.

Filter apparatus according to spoke 1, characterized by resilient scrapers (D ) attached to the wall of the housing (A) , which lean against the filter body (C) during the upward movement of the same and cause the filter to be cleaned, the removed dirt particles being thrown out by it water flowing around the filter can be carried away.
