Das Gestell oder der Rahmen A ist mit einem Schlitz oder Einschnitt A¹ versehen, der im Boden des Gestelles angebracht ist, wodurch zwei Seitentheile BB gebildet werden. In jedem Theil B ist eine geneigte Rinne C angebracht, in welcher ein Gleitbacken D montirt ist, der durch die Seiten der Rinne ge-' führt wird. An jeder Backe ist. ein Arm D¹ befestigt, derart, dafs ein Ende des Armes sich in einem passenden Ausschnitt in jeder Backe befindet, Fig. 1, und das andere Ende in Schlitzen eines Querstückes E befestigt ist, das in dem Ausschnitt E^l des Gestelles A auf- und abgleiten kann. Eine Schraube F geht durch Oeffnungen in dem Theil des Gestelles, welcher dem Einschnitt A^x gegenübersteht, und durch Oeffnung F¹ in dem geschlossenen Ende des Einschnittes A¹. Die Oeffnungen im Gestell A, durch welche Schraube F geführt ist, sind nicht mit Gewinde versehen und kann die Schraube frei durch dieselbe geführt werden ; nur die Oeffnung in dem Querstück E ist mit Gewinde versehen.The rack or frame A is provided with a slot or incision A ¹ which is made in the bottom of the rack, whereby two side parts BB are formed. In each part B an inclined channel C is made, in which a sliding block D is mounted, which is led through the sides of the channel. There is on every cheek. an arm D ^{1 is} fastened in such a way that one end of the arm is located in a suitable cutout in each jaw, Fig. 1, and the other end is fastened in slots of a cross piece E which is located in the cutout E ^{l of} the frame A. and can slide. A screw F passes through openings in the part of the frame opposite the incision A ^x and through opening F ¹ in the closed end of the incision A ¹ . The openings in the frame A, through which screw F is passed, are not provided with a thread and the screw can be passed freely through the same; only the opening in the crosspiece E is provided with a thread.

Das innere Ende jeder Backe D, welches dem Einschnitt am nächsten steht, ist mit einer Meifselspitze α versehen und von dieser geht eine Curve zum anderen Ende. Diese kann glatt oder geriffelt sein. Das Gestell A wird über die Stange G oder einen anderen Artikel, der durch die Klammer gehalten werden soll, geschoben, bis der Gegenstand auf dem geschlossenen Theil des Schlitzes aufruht und die Schraube F in ihrer Längenrichtung bewegt wird, wie Pfeil α¹ angiebt, bis das Querstück E durch das Berühren der Backen mit Stange G angehalten wird.The inner end of each jaw D, which is closest to the incision, is provided with a chisel point α and from this a curve goes to the other end. This can be smooth or corrugated. The frame A is pushed over the rod G or another article which is to be held by the clamp until the article rests on the closed part of the slot and the screw F is moved in its longitudinal direction, as indicated by arrow α ¹ , to the crosspiece E is stopped by touching the jaws with rod G.

Bei dieser Bewegung des Querstückes E werden die Arme D¹ der Backen D in die in Fig. 2 gezeigte Stellung gebracht.During this movement of the crosspiece E , the arms D ^{1 of} the jaws D are brought into the position shown in FIG.

Durch Anziehen der Schraube F in der Richtung des Pfeiles a^x wird das innere Ende derselben von dem geschlossenen Ende des Einschnittes A¹ entfernt. Die Schraube F wird dann so gedreht, um in der dem Pfeile a¹ entgegengesetzten Richtung bewegt zu werden,By tightening the screw F in the direction of arrow a ^x , the inner end thereof is removed from the closed end of the incision A ^1. The screw F is then turned so as to be moved in the direction opposite to the arrow a ^1,

Claims

until its inner part presses against the rod G.

If you continue the rotation of the screw in the can go no further the arrows a ^l opposite direction, since it stöfst against bar G, the latter is held by jaws D, the cross-piece E is slowly in the direction 'of arrow a ¹ moved, wherein the chisel tips are pressed into the surface of the rod G or at least pressed with sufficient pressure to prevent slipping.

If the rod G is to be removed again, the screw JP is loosened so that the crosspiece E can be moved in the direction opposite to the arrow, the jaws D being removed from one another and the rods G released. The frame A can be provided with any handle.

In the construction shown in Fig. 6, the frame or the frame with two ent-. The opposite handle c is provided for turning the same and the inner ends of the sliding jaws D are standing. above. The latter rest on the block K with a V- notch K ¹ , in which block the inner end of the screw F is rotatably mounted, the block being fixed and without any movement.

In the construction used in FIG. 7, only one handle J ^{1 is} provided. At the closed end of the slot A ^x , the arm L is rotatably attached to the frame, one end of the arm being corrugated or toothed and the other end facing the screw F being curved.

If desired, the screw F can be provided with a head M which is attached in such a way that the screw can rotate on it, the head being guided in the frame to enable movement in the longitudinal direction of the screw F. The head M is provided on its upper part with a circular or segmental widening for receiving the rod or the tube, Fig. 8.

The jaws D can in any case be provided with the chisel point α , or segmental widenings which fit on the cylindrical object, such as a rod or tube, can be provided, as shown in FIG.

To hold a boring iron or a thread cutting disk, the screw JP is turned so that the crosspiece E and the arms JD ^{1 are moved} in the direction of the arrow d ¹ , Fig. 6, with the inner sides of the jaws being moved away from each other and up in this way form an incision to receive the disc or the drill bit. The direction of rotation of the screw F is then reversed in order to be able to move the crosspiece E in the direction opposite to the arrows d ¹ , the jaws being pressed against the walls of the frame.

The frame A is rotated by means of the handle J and can be used as a clip or drill iron holder. Drills etc. of any size can easily be held in the frame, and adjusted, fastened and loosened very quickly and easily.

In the construction shown in Fig. 7, a boring iron which is rotated by .Handhabe J ¹ , the screw JP is turned so that the whole moves in the direction opposite to the arrow h ^1. to allow the jaw L to slide down into the slot in the frame. The pipe P is placed on the closed end of the incision A ¹ and the screw Fin is moved in the opposite direction to the arrow h ¹ , the crosspiece E is moved in the same direction and the inner surfaces of the jaws D are pressed against said rod or the pipe . The screw F is then turned so as to be moved in the direction of the arrow h ¹ and to raise the inner part of the toothed jaw L. If the device is turned in the direction of the arrow ni ¹ , the toothed side, the jaw L, does not attack the rod; but if the device is rotated in the opposite direction, the teeth of the jaw L engage the tube or rod P and rotate the same in the direction shown by arrow n ¹ in FIG.

The individual parts can be adjusted so that the tube can be held fast and easily and let go and that the teeth always attack the pipe.

Patent claim:

". A clamping device, essentially consisting of a frame piece A in the side parts of which the clamping jaws D are guided in matching slots in such a way that they are connected by the rods D ¹ to the rail E, which is influenced by the screw F and is correspondingly guided in the base piece a rotation of the screw make a completely, even movement exactly corresponding to this rotation and the screw either carries a third clamping jaw or acts on a laterally rotatably attached intermediate piece or directly serves as a clamping jaw, for the purpose of adjusting the position of all clamping jaws by means of a single screw to be able to adjust precisely and hold on to the object in question.
