PATENTAMT.PATENT OFFICE.

Für manche Zwecke ist es erforderlich, zwei Apparate durch zwei Schläuche miteinander zu verbinden und an beiden Anschlußstellen beide Schläuche abzudichten. So sind zur Leitung der Luft bei Werkzeugen, deren Antrieb durch schwingende Luftsäulen erfolgt, zwei Schläuche erforderlich, welche je einen der beiden Zylinderräume der Luftpumpe mit ' einem der beiden Zylinderräume des Werkzeuges verbinden. Sowohl an der Luftpumpe als am Werkzeug müssen je zwei Anschluß-For some purposes it is necessary to connect two apparatuses through two hoses to connect and to seal both hoses at both connection points. So are for Air conduction in tools that are driven by vibrating air columns, two hoses are required, each with one of the two cylinder chambers of the air pump 'Connect one of the two cylinder chambers of the tool. Both on the air pump than on the tool, two connection

• stellen für die beiden Schläuche vorhanden sein. Ordnet man die beiden Anschlußstellen für die Schläuche an der Luftpumpe bzw. am Werkzeug getrennt voneinander an, so müssen wegen der Befestigungsmittel die beiden Schlauchenden verhältnismäßig weit voneinander ab liegen, wodurch die leichte Beweglichkeit des durch die Luftschläuche mit der Luftpumpe verbundenen Werkzeuges gehindert wird. Außerdem ist die Befestigung und Abdichtung der vier Schlauchenden umständlich und zeitraubend. • Make available for the two hoses. If one arranges the two connection points for the hoses on the air pump or on the tool separately from each other, so must be due to the fastening means, the two hose ends are relatively far from each other, thereby the easy mobility of the connected by the air hoses to the air pump Tool is prevented. In addition, the fastening and sealing of the four hose ends cumbersome and time-consuming.

Man hat diese Übelstände dadurch zu beheben gesucht, daß man einen aus zwei konzentrisch ineinandergesteckten Schläuchen bestehenden Doppelschlauch mittels ringförmig . übereinandergreifender, gegeneinander abzudichtender Schlauchtüllen gegen die konzen- trisch angeordneten Mündungen der beiden Luftleitungen der Luftpumpe bzw. des Werkzeugs abdichtete. Mit dieser Anordnung waren aber die Nachteile verbunden, daß die Anschlußstücke verhältnismäßig kompliziert waren, daß zwei Schläuche von verschiedenem Durchmesser angewendet werden mußten, deren Ersetzung dadurch erschwertwurde, daß die Luft in dem ringförmigen Zwischenraum zwischen dem innern und dem äußern Schlauch eine beträchtliche und die Nutzleistung verringende Reibung erfuhr, und daß auch die Beweglichkeit des Werkzeuges durch den dickeren Schlauch etwas herabgesetzt wurde.Attempts have been made to remedy these deficiencies by concentrically forming one of two nested hoses existing double hose by means of a ring . overlapping hose nozzles to be sealed against each other against the concentrated trically arranged mouths of the two air lines of the air pump or the tool sealed. With this arrangement, however, the disadvantages were associated that the connecting pieces relatively complicated that two hoses of different diameters had to be used, the replacement of which was made difficult by the fact that the air in the annular space between the inner and the outer tube a considerable and the friction which reduces the efficiency, and that also the mobility of the Tool has been slightly reduced by the thicker hose.

Gemäß vorliegender Erfindung werden die oben genannten Übelstände auf anderem Wege behoben. Es werden in an sich bekannter Weise zwei gewöhnliche Schläuche angewendet, deren Enden dicht nebeneinander an der Luftpumpe bzw. am Werkzeug befestigt werden können. Die neue Anordnung besteht in einer Doppelschlauchtülle, deren beide Bohrungen dicht nebeneinander in einen zylindrischen Hals münden, dessen vorspringender Rand durch eine Überwurfmutter gegen ein mit zwei Bohrungen und Außengewinde versehenes Zwischenstück festgepreßt wird. An sich ist eine Vorrichtung zum Verbinden von nur zwei Rohrenden bekannt, bei welcher der Anschluß unter Benutzung eines Zwischenstückes und einer Überwurfmutter geschieht. Demgegenüber bezweckt aber die Einrichtung nach vorliegender Erfindung, zwei getrennt nebeneinander liegende Rohrteile miteinander zu befestigen und abzudichten. Diese Vorrichtung beansprucht einen kleinen Raum und erfordert nur wenige und einfache Teile. Die Befestigung und Lösung lassen sich schnell mit einem einzigen Griff bewirken.According to the present invention, the above-mentioned inconveniences are dealt with in other ways Fixed. Two ordinary hoses are used in a manner known per se, the ends of which are fastened close together on the air pump or on the tool can. The new arrangement consists of a double hose nozzle with both holes open close to each other in a cylindrical neck, the protruding edge of which by a union nut against one with two bores and external thread Intermediate piece is firmly pressed. In itself is a device for connecting only two pipe ends known, in which the connection using an intermediate piece and a union nut happens. On the other hand, however, the establishment aims According to the present invention, two pipe parts lying separately next to one another are closed with one another fasten and seal. This device occupies a small space and requires few and simple parts. The attachment and detachment can be done quickly with a single grip.

Claims

The invention is shown in the drawing in an exemplary embodiment, namely: FIG. 1 is a front view of the device, FIG. 2 is the same view in section,
Fig. 3 is a side view in section along the line 3-3 of Fig. 1,

FIG. 4 shows the bottom view of the intermediate piece d, FIG. 5 shows an upper view of the double hose nozzle f,

Fig. 6 in section along the line 6-6 of FIG. 2, the double hose nozzle f and the over-. union nut e during the introduction and formation of the ring g used to attach the union nut.
The channels a ¹ and α ² leading to the two cylinder sides of the air pump or the tool open side by side into a flat surface b, against which an intermediate piece d can be screwed by means of two head screws c, which the two segment-shaped bores d ¹ and d ² and is provided with an external thread d ^s . A double hose nozzle f is screwed onto the intermediate piece d by means of a union nut β. The double hose nozzle f has two bores f ¹ and Z " ² , which at the connection point • are close to each other, adjoin the bores d ¹ , d * of the intermediate piece d and are laterally deflected so that the two hose nozzles are at a sufficient distance from each other, in order to be able to pull the two hose ends over the two hose nozzles.

In order to secure the correct position of the double hose nozzle f ^s against the intermediate piece d , this carries a pin ⁴ on the side, which engages in a corresponding hole in the double hose nozzle f! The double hose nozzle f. Has a protruding edge f ³ , against which a corresponding projecting edge of the union nut should rest when the double hose nozzle is to be fastened to the intermediate piece d by means of the union nut. But since the distance of the outermost points of the two sleeves is significantly greater than the diameter of the protruding edge f ³ , the nut must be pushed over the edge f ³ and the protruding edge of the nut must be created later. This is done in such a way that the union nut e has an annular recess e ² (FIGS. 2, 3 and 6) and a bore e ^z opening tangentially into this (FIGS. 1 and 6). For fastening, the nut is pushed over the protruding edge f ^s and a steel pin g of the appropriate length is then inserted through the bore e ^{3 and hammered in with a hammer.} The pin is forced to fold over in the annular cavity formed on the one hand by the annular groove e ³ and on the other hand by the cylindrical surface of the body f located below the protruding edge f ³ and to form a ring. The length of the pin g must be slightly smaller than the circumference of the ring to be formed. The last end of the pin g is driven in by means of a mandrel. '-

Godfather τ-An saying:

Device for the simultaneous production or for the simultaneous release of the connection of two separate, adjacent hoses, characterized by a double hose nozzle (f), the two bores (f ¹ and f ² ) of which open close to one another into a cylindrical neck, the protruding edge of which (f ³ ) by such a union nut (e) is pressed tightly against an intermediate piece (d) provided with two bores (d ¹ , d ² ) and external thread ^{(d 3).}
