gegeneinander verstellbar sind.are mutually adjustable.

Das bisher allgemein angewendete Verfahren des Spannens von Sägen in den Gatterrahmen der Vollgatter ist als ein recht umständliches und unzweckmäßiges empfunden worden; es muß danach, wie bekannt, jede einzelne Säge mittels der Sägenangel gespannt und ebenso gelöst werden.The previously generally used method of clamping saws in the gate frame the full gate is felt to be quite cumbersome and inexpedient been; Then, as is known, every single saw must be tensioned by means of the saw tang and be solved as well.

Es ist bereits bekannt, sämtliche Sägen eines Gatters sowohl einzeln als auch gemeinsam durch eine Schraube zu spannen. Ferner sind Gattersägen bekannt, bei denen die beiden Gatterrahmenbalken durch Schrauben gegeneinander eingestellt werden können, die an den Gatterrahmensäulen angebracht sind.It is already known that all saws of a frame both individually and together to be tensioned by a screw. Furthermore, gang saws are known in which the both gate frame beams can be adjusted against each other by screws that are attached to the gate frame pillars.

Da aber bei der gleichzeitigen Spannung sämtlicher Sägen an Vollgattern sehr große Kräfte zu überwinden sind, so dürften einfache Schrauben nicht genügen. Beim Erfindungsgegenstand ist der Gatterrahmen derartig ausgebildet, daß durch gemeinsam angezogene Differentialschrauben die Gatterrahmenbalken auseinander bewegt werden und somit sämtliche Sägen gemeinsam angespannt bezw. gelöst werden können.But since all the saws on full creel are tensioned at the same time, they are very large Forces have to be overcome, simple screws should not be enough. With the subject matter of the invention the gate frame is designed in such a way that the gate frame beams by means of jointly tightened differential screws are moved apart and thus all the saws clamped together respectively. can be solved.

Der neue Gatterrahmen ist in Fig. 1 bis 3 der Zeichnung dargestellt, und zwar zeigt Fig. ι die Gesamtanordnung, während die Fig. 2 und 3 einzelne Teile der Gesamtanordnung veranschaulichen. ^r The new gate frame is shown in Fig. 1 to 3 of the drawing, namely Fig. Ι shows the overall arrangement, while Figs. 2 and 3 illustrate individual parts of the overall arrangement. ^r

Der eine Gatterrahmenbalken α (Fig. 1) ist durch die Differentialschrauben c mit den Gatterrahmensäulen b verbunden.One gate frame beam α (Fig. 1) is connected to the gate frame columns b by the differential screws c .

Aus der Fig. 2 geht hervor, daß die Differentialschrauben zum Zweck ihrer Drehung oberhalb des Gatterrahmenbalkens α verlängert und daselbst mit einem kantigen Kopf versehen sind, an welchem die Bewegungsvorrichtung angreifen kann.From Fig. 2 it can be seen that the differential screws are extended for the purpose of their rotation above the gate frame beam α and there are provided with an angular head on which the movement device can act.

Das Gewinde ist nicht unmittelbar in der Gatterrahmensäule angeordnet, sondern in einer Buchse 0, welche auf dem Ende der Gatterrahmensäule in einer Kugelfläche aufliegt und nach oben zu mittels einer Gewindehülse ρ ebenfalls in einer Kugelfläche umschlossen wird; auf diese Weise 'ist eine geringe Verschiebung der Gewindebuchse 0. in der Säule möglich, falls durch eine Durchbiegung des Gatterrahmenbalkens ά sowie der Gatterrahmensäulen b die Schraube c etwas schief zu stehen kommt; q ist ein Ver-Stärkungsring, der mit der Gatterrahmensäule b fest verlötet ist und das Gewinde für die Gewindehülse ρ trägt; der Wulst, s an: der Gewindebuchse 0, der natürlich die Einstellung der Kugelflächen nicht hindern darf, zentriert die Buchse bei etwaiger Verschiebung stets gegen die innere Wandung der Gatterrahmensäule b. Damit die Gewindebuchse ο und die Schraube c sowie der Gatterrahmenbalken α sich nicht auch in der Richtung senkrecht zur Zeichnung (d. h. in Richtung der Sägen) aus der Richtung der Achse der Säule b verschieben (kippen) kann, hat die Gewindebuchse 0 senkrecht zur Zeichnung keinen Spielraum in der inneren Wandung der Gatterrahmensäule b; vielmehr hat hier die Gewindebuchse in ihrer ganzen Länge auch das Durchmessermaß des Wulstes s undThe thread is not arranged directly in the gate frame column, but in a socket 0, which rests on the end of the gate frame column in a spherical surface and is also enclosed in a spherical surface towards the top by means of a threaded sleeve ρ ; In this way, a slight displacement of the threaded bushing 0 in the column is possible if the screw c comes to stand at a slight angle due to a bending of the gate frame beam ά and the gate frame columns b; q is a reinforcement ring that is firmly soldered to the gate frame column b and carries the thread for the threaded sleeve ρ; the bead, s on: the threaded bushing 0, which of course must not prevent the setting of the spherical surfaces, always centers the bushing against the inner wall of the gate frame column in the event of any displacement b. So that the threaded bushing ο and the screw c as well as the gate frame beam α cannot shift (tilt) from the direction of the axis of the column b in the direction perpendicular to the drawing (i.e. in the direction of the saws), the threaded bushing 0 perpendicular to the drawing does not have any Clearance in the inner wall of the gate frame column b; rather, here the threaded bushing also has the diameter of the bead s and in its entire length

Claims

so lies tightly against the inner wall of the gate frame column in its entire length; Of course, the described mobility of the threaded bushing ο is not required, ι as soon as a bending of the gate frame beam α and the gate frame columns b is not to be feared. 'r are holes in the upper end of the screw c through which the lubricating material for ίο lubricating the two threads can be fed. In Fig. 3, the differential screws c are designed so that both threads in the gate frame beam α are, in such a way that a bushing is used in the latter, the outer thread of which is in engagement with the frame beam, while the inner thread in the thread of a engages screw spindle firmly connected to the gate frame column. A particularly useful device for rotating the screws c is shown in the drawing (Fig. 1); the same consists of the two spindles e guided in bearing guides d, each of which has a mouth at its lower end that fits onto the angular ends of the screws c. At their upper end, the spindles carry e bevel gears f, which are driven by the bevel gears h sitting on the shaft g and by the pair of bevel gears i, the. Shaft k and handwheel I are moved; the latter is conveniently located next to the full gate for the attendant; With the exception of the bearing guides d, all named parts of the clamping device are attached to a frame R, which hangs by means of a rod m on the lever H, which carries a counterweight G on its other arm, which balances the weight of the device is, it is very easy to couple the spindles e with the screws c and move the screws c, as already described above. If the required tension 45 or loosening of the saws has taken place, the spindles e and the screws c are uncoupled. Of course, the movement of the shaft g can also take place by any other drive means instead of the bevel gears i and shaft k; the movement of the shaft g could also be effected by power operation instead of by hand. The saws are tensioned in the new frame as follows: The saws are hung in the frame a b and the wedges, eccentrics or the like are tightened on them in such a way that the saws can be straightened. Then the clamping device is placed on the angular heads of the differential screws and the latter is rotated until the saws are fully tensioned. A simultaneous release of all saws is achieved by simply turning back the clamping device. Patent approval ε:
