Die Bewegung der forttreibenden Organe erfolgt in bekannter Weise während des gröfsten Theiles ihres nutzbaren Wirkens parallel mit der Laufachse des Fahrzeuges. Die den Gegenstand der Erfindung bildende Antriebsvorrichtung ist in den Fig. 1 bis 7 dargestellt.The movement of the propulsive organs takes place in a known manner during the largest Parts of their useful work parallel with the running axis of the vehicle. The the subject The drive device forming the invention is shown in FIGS.

An den beiden Seiten eines Wasserfahrzeuges sind aufsenbords, durch Gelenkketten f mit einander verbunden, je zwei Kettentrommeln b und c angeordnet, deren Achsen b' und c' gemeinsam auf einem mit dem Schiffskörper in beliebiger Weise zu verbindenden Gestell a . in der Weise lagern, dafs die untere Kettenlänge sich dicht über dem Wasserspiegel, genau parallel mit ihm, befindet. Die einander zugekehrten Enden der Achsen b' tragen Kettenscheiben d, die mit Scheiben e, deren Achsen e' ebenfalls auf dem Gestell α ihre Lagerung finden, durch Gelenkketten h verbunden sind: Die letzteren sind mit je einer Griffstange g versehen, an welchen ihre Fortbewegung und mit dieser die Drehung der Achsen b' und c' und der mit ihnen verbundenen Kettentrommeln b und c erfolgt.On the two sides of a watercraft, two chain drums b and c are arranged on the outboard, connected to each other by articulated chains f , the axes b ' and c' of which are jointly mounted on a frame a that can be connected to the hull in any way. store in such a way that the lower length of the chain is just above the surface of the water, exactly parallel to it. The facing ends of the axes b ' carry chain pulleys d, which are connected to disks e, the axes e' of which are also supported on the frame α , by articulated chains h : the latter are each provided with a handle bar g on which their movement and with this the rotation of the axes b ' and c' and the chain drums b and c connected to them takes place.

Die Bolzen gg', Fig. 4 bis 7, sind einanderThe bolts gg ', FIGS. 4 to 7, are mutually exclusive

. genau gegenüberstehend in die Glieder der Gelenkketten h h' eingenietet und passen genau in die Bohrungen der Kurbelarme GG'. Der Arm K der Kurbel G K hat eine Bohrung, in welche der Zapfen K' der Kurbel G' K' genau eingepafst ist.. riveted exactly opposite into the links of the link chains hh ' and fit exactly into the bores of the crank arms GG'. The arm K of the crank GK has a bore into which the pin K 'of the crank G' K 'is precisely fitted.

Die die Vorrichtung handhabende, auf dem Sitzbrett A ruhende Person erfafst mit je einer Hand die Kurbelarme G und G'. Bewegt sie nun die Hände rückwärts und hierdurch die Kurbelarme G G' in der Richtung der Pfeile (Fig. 4 und 5), so werden vermittelst der Bolzen g g' die beiden Gelenkketten h h' in derselben Richtung, und zwar beide zusammen bewegt. Der Verbindungsarm if der Kurbel G K bewirkt alsdann im Verein mit dem Bolzen K' der Kurbel G' K' ein starres Gebilde, eine Aussteifung der Gelenkketten h h' gegen einander bildend. Man kann also, ohne die beiden Hände von den Kurbelarmen G G' abzunehmen, die Bolzen g g' und somit die Gelenkketten h h' sowohl in der oberen und unteren horizontalen Strecke der Gelenkkette als auch um die Ketten d e und d' e' in der Richtung der Pfeile so herumführen, dafs die Längsachsen der Bolzen g g' stets in eine gerade Linie 'fallen. Ebenso kann aber auch die Bewegungsrichtung beider Gelenkketten gleichzeitig in einer der Pfeilrichtung entgegengesetzten Richtung erfolgen (Fig. 6 und 7).The person who handles the device and who is resting on the seat board A grasps the crank arms G and G 'with one hand each. If she now moves her hands backwards and thereby the crank arms GG 'in the direction of the arrows (FIGS. 4 and 5), the two link chains hh' are moved in the same direction by means of the bolt gg ' , both moving together. The connecting arm if of the crank G K then, in conjunction with the bolt K 'of the crank G' K ', creates a rigid structure, forming a stiffening of the link chains hh' against one another. So you can, without removing your two hands from the crank arms GG ' , the bolts gg' and thus the link chains h h ' both in the upper and lower horizontal section of the link chain and around the chains de and d' e ' in the direction of Move the arrows around in such a way that the longitudinal axes of the bolts g g ' always fall into a straight line'. However, the direction of movement of both link chains can also take place simultaneously in a direction opposite to the direction of the arrow (FIGS. 6 and 7).

Man kann sich daher die Kurbelarme G G' auch durch die Griffe von zwei Rudern ersetzt denken, mit welchen der Steuermann auf dem Sitz A arbeiten würde, nur dafs im vorliegenden Falle die Zeit, welche bei dem Herausheben der Ruder aus dem Wasser und deren Rückwärtsbewegung thatsächlich verloren geht, ausgenutzt wird. Eine Drehung der Doppelkurbel GKG' im Sinne einer Kurbelbewegung findet also nicht statt.One can therefore imagine replacing the crank arms GG 'with the handles of two oars, with which the helmsman on seat A would work, only that in the present case the time actually spent lifting the oars out of the water and moving them backwards is lost, is exploited. A rotation of the double crank GKG ' in the sense of a crank movement does not therefore take place.

Will man nun das Fahrzeug wenden oder um einen gewissen Winkel aus seiner Fahrrichtung herausdrehen, so müssen die Gelenkketten h h' unabhängig und in entgegengesetzter Richtung von einander arbeiten können. Diese Unabhängigkeit der Bewegung der Gelenkketten h h' ermöglicht die Doppelkurbel G K G'. Aber auch in diesem Falle wird nicht an dem Mittel-If you want to turn the vehicle around or turn it out of its driving direction by a certain angle, the link chains hh ' must be able to work independently and in opposite directions from one another. This independence of the movement of the link chains hh 'is made possible by the double crank G K G'. But even in this case, the middle

part K of the double crank and there is also no rotation in the sense of a crank movement, rather one only works here with the aid of the crank arms GG '.

If you imagine KGG 'of the double crank lying in a straight line, if you intend to turn the boat, the left hand will pull the crank arm G' away from you, the right hand will pull the crank arm G towards you; then the crank arm K with the crank pin K 'will be the axis of rotation around which G and G' swing, and the rigid structure of the double crank GKG ', as in the case described above, will protect the link chains hh' against bending.

The bolts gg ' riveted into the link chains now run through in exactly the same way as previously described - only in opposite directions to each other - the paths in the upper and lower horizontal sections and the paths around the chain pulleys de and d' e ' around .

But one can also move the crank arms GG ', FIG. 6, in the direction of the dotted arrows; then the boat turns in the opposite direction to that under consideration. . The link chains f of the drums b and c in the main drawing are equipped with the two blades m which are exactly opposite each other and which are held at right angles to the chains by tie rods η. The translation relations for moving said blades are selected such that unique gera'dlinigen reciprocations DAF each a handle g the rectilinear motion of each of a blade in the water causes and absorbed, dead point in the position of the blades at the same time second with each change of movement of its Handle bar collapses.

The above device enables both forward and reverse driving for the concerned Vehicles with the same great effect, as well as their control and quick turning. The handling of the handlebars is the same as that of the oars, only the movements be straight and parallel and the actuating force both with pulling as with Pressure increase comes into effect continuously.

PATENT CONTACT:

Handle for driving endless shovel chains arranged on both sides of the boat, Consists of two ~ "| _ -shaped handles that can be rotated with the Countershaft chains attached handles, as well as rotatably connected to each other, so that at in the same direction and falling in the direction of movement of the handles the lay-up chains and through this the shovel chains are moved uniformly in the same direction, whereas with angled or oppositely directed position of the handles, the countershaft chains BEZW. Bucket chains can be moved independently of each other.
