 der Kolbenstange angreifende Feder 33 in seine urspriingliche Lage   zurückgezogen   wird. Durch Zurücklegen des Hebels 26 wird der Wagen 13 samt dem Rahmen von der Dehnungsvorrichtung gelöst und kann sodann mittels des Hebels 20 in die lotrechte Lage gebracht und durch die Haken 24 in dieser Lage festgehalten werden. Hierauf wird der Rahmen samt der Haut von den Trägern 19 entfernt und die Haut in gespanntem Zustand am Rahmen zum Trocknen gebracht. 



   Da sowohl das Rahmengestellt als auch das Gestell der Dehnungsvorrichtung auf Rollen ruht, ist es möglich, die Maschine an eine beliebige Stelle der Werkstätte zu schieben. 



   PATENT-ANSPRÜCHE :
1. Maschine zum Dehnen von Häuten u. dgl., gekennzeichnet durch einen vorteilhaft fahr-und kippbaren Spannrahmen für die Haut und durch eine mit dem Rahmenträger in lösbare Verbindung stehende Dehnungsvorrichtung, die aus einem einen Teil des Rahmens samt der eingespannten Haut verschiebenden Zugorgan besteht, welches ebenfalls vorteilhaft fahrbar angeordnet und gleich dem verschiebbaren Spannrahmenteil in bestimmten Lagen feststellbar ist.

 the spring 33 engaging the piston rod is withdrawn into its original position. By moving the lever 26 back, the carriage 13 together with the frame is released from the stretching device and can then be brought into the vertical position by means of the lever 20 and held in this position by the hooks 24. The frame together with the skin is then removed from the carriers 19 and the skin is brought to dry in the tensioned state on the frame.



   Since both the frame and the frame of the stretching device rest on rollers, it is possible to push the machine anywhere in the workshop.



   PATENT CLAIMS:
1. Machine for stretching skins u. Like., characterized by an advantageously mobile and tiltable clamping frame for the skin and by a detachable connection with the frame support expansion device, which consists of a part of the frame including the clamped skin, which is also advantageously arranged to be mobile and the same movable clamping frame part can be determined in certain positions.

Claims

2. Machine according to claim 1, characterized in that the clamping frame is formed from parallel tubes (14) which are detachably mounted on supports (19) and, together with these, about supports (22) tiltable, and from clamping plates (15, 16) connecting the same, of which the one with respect to the other, fixed, can be moved.

3. Machine according to claim 1, characterized in that the expansion device consists of a piston displaceable by hydraulic or other pressure, the rod (5) of which is connected by a crosshead (7) with threaded rods (10) which are connected to the displaceable clamping plate ( 16) of the clamping frame can be coupled and adjusted by means of adjustable stop nuts with reference to the crosshead (7).

4. Machine according to claim 1 to 3, characterized in that the piston rod (5) is adjustable and lockable with respect to the crosshead (7) and the displaceable clamping plate (16) with respect to the frame tubes (14), ' 5. Machine according to claim 1 to 3, characterized in that the coupling of the clamping frame with the tension member is effected by the threaded rods (10) which can be pushed into the displaceable clamping plate (16) and can be locked by screws or the like, the frame tubes (14 ) on pin (30) EMI2.1 EMI2.2
