Die bisher bekannten Horizontalgattersägen I mit mehreren von einem gemeinsamen An- ! trieb bewegten Sägegattern haben den Nachteil, daß die Sägegatter stets nur gleichzeitig bewegt werden können. Selbst also für den Fall, daß nur ein Teil der Sägen benutzt werden soll, müssen die übrigen nebenher im Leerlauf angetrieben werden, es sei denn, daß vorher ein teilweiser Abbau der Maschine, insbesondere der Schubstangen vorgenommen wird. Der mit dem Leerlauf verbundene Arbeitsverlust kann also höchstens durch einen mit dem Abbau verknüpften Zeitverlust vermieden werden.The previously known horizontal frame saws I with several of a common attachment! driven moving saw frames have the disadvantage that the saw frames only ever simultaneously can be moved. Even in the event that only some of the saws are used is to be, the others must be driven at the same time in idle, unless that a partial dismantling of the machine, in particular the push rods, was carried out beforehand will. The loss of work associated with idling can therefore at most be caused by one loss of time associated with dismantling can be avoided.
Diese Übelstände werden gemäß der Erfindung dadurch beseitigt, daß die zum Antrieb der Gatterrahmen dienenden Kurbeln mit ausrückbarem Antrieb von einer gemein- j samen Welle aus bewegt werden. jThese drawbacks are eliminated according to the invention in that the drive the gate frame serving cranks with disengageable drive are moved by a common shaft. j
Die Zeichnung veranschaulicht die Erfin- ; dung durch Fig. ι in der Vorderansicht und Fig. 2 in der Draufsicht. > The drawing illustrates the invention; Training by Fig. ι in the front view and Fig. 2 in plan view. >
Die an den unterteilten Ständern b gela- I gerten Sägebänke c dienen als Führungen für die Gatterrahmen d mit Sägeblättern d1. An die Gatterrahmen d greifen die von den Kurbelscheiben e kommenden Schubstangen f an. Die Wellen der Kurbelscheiben e werden von der Welle g mittels Fest- und Losscheiben h, i durch Riemen k angetrieben. Von der Welle g kann ferner in vorteilhafter Weise auch der maschinelle Antrieb der Höheneinstellung für die Sägebänke c abgeleitet werden. Ein entsprechendes Rücken der Riemen k auf den Fest- und Losscheiben h, i ermöglicht nach Belieben ein Arbeiten der Sägen einzeln oder gemeinsam.The saw benches c mounted on the subdivided uprights b serve as guides for the gate frames d with saw blades d 1 . The push rods f coming from the crank disks e attack the gate frame d . The shafts of the crank disks e are driven by the shaft g by means of fixed and loose disks h, i through belts k . The mechanical drive for the height adjustment for the saw benches c can also advantageously be derived from the shaft g. A corresponding back of the belt k on the fixed and loose pulleys h, i allows the saws to work individually or together, as desired.
