PATENTAMTPATENT OFFICE

Gegenstand der vorliegenden Erfindung ist eine Antriebs- und Einstellvorrichtung für den Haspel von Bindemähern, die den Zweck hat, die Halme in dem Maße, wie sie durch das Messer geschnitten werden, auf das endlose Tuch auszubreiten, wobei die Haspelachse in alle notwendigen Lagen gebracht und in einer beliebigen derselben festgestellt werden kann. Bei den bekannten derartigen HaspelnThe present invention is a drive and adjustment device for the reel of binding mowers, which has the purpose of removing the stalks as they go through the knife to be cut, spread on the endless cloth, with the reel axis brought into all necessary positions and fixed in any of them can. In the known such reels

ίο ist entweder die Haspelachse um die Antriebswelle drehbar angeordnet, wobei zur Drehung Schraubengetriebe Verwendung finden; die Haspelachse kann aber dann nicht an die Antriebswelle herangebracht werden, so daß die Einstellbarkeit innerhalb enger Grenzen bleibt, oder es sind, wenn die Haspelwelle auf der einstellbaren Tragstange oder dergl. nach der Antriebswelle hin verschoben werden kann, die empfindlichen, schwer auszubessernden Universalgelenke nötig, so daß das Getriebe nicht einfach genug ausfällt. Bei anderen Einrichtungen wiederum, bei denen der Antrieb einfach durch eine Kette erfolgt, bedarf es zur Einstellung besonderer Klinkvorrichtungen, die den Betrieb unsicher machen.ίο is either the reel axis around the drive shaft arranged to be rotatable, with screw gears being used for rotation; the But then the reel axis cannot be brought up to the drive shaft, so that the Adjustability remains within narrow limits, or there are when the reel shaft on the adjustable support rod or the like. Can be moved towards the drive shaft, the sensitive universal joints that are difficult to repair are necessary, so that the transmission does not turns out simple enough. In other devices, in turn, where the drive is simply carried out by a chain, it is necessary to Adjustment of special ratchet devices that make operation unsafe.

Durch die vorliegende Erfindung sollen die Obigen Nachteile behoben werden, und zwar dadurch, daß die, wie oben angegeben, in bekannter Weise in einem unter verschiedenen Winkeln einstellbaren Rahmen gleitende Haspelachse mit der einen Spitze eines ausstreckbaren Parallelogramms verbunden wird, dessen Diagonale durch den erwähnten Rahmen gebildet wird. Der Antrieb erfolgt dabei durch eine um das Parallelogramm herumgelegte Kette, und das Einstellen beider Bewegungsrichtungen wird durch ein und dieselbe Vorrichtung bewirkt.The above disadvantages are to be eliminated by the present invention in that, as indicated above, in a known manner in one of different Angle adjustable frame sliding reel axis with one tip of an extendable Parallelogram is connected, the diagonal of which is formed by the frame mentioned. The drive is done by a chain wrapped around the parallelogram, and the setting of both directions of movement is done by one and the same device causes.

ι ist der unter verschiedenen Winkeln einstellbare, im Maschinenansatz 2 drehbar gelagerte Rahmen. Die Achse 3 des Haspels ist in der einen der beiden auf dem Rahmen 1 gleitenden Hülsen 4, 4 gelagert. Die Achse 3 geht durch die die Spitze des aus den vier Schenkeln 6 bestehenden Parallelogramms bildende Hülse 5. Der Mittelpunkt der unteren Parallelogrämmspitze liegt in der Mittelpunktachse des im Ansatz 2 gelagerten Rahmenteiles. An den vier Spitzen des Parallelogramms sind kleine Kettenräder 8 angeordnet, um welche eine gemeinsame Kette 9 geführt ist. Das obere Kettenrad sitzt auf der Nabe des Haspels, das untere Kettenrad 8 dagegen ist mit einem Schraubenrad 10 verbunden, welches von einer Schnecke 11 seinen Antrieb erhält, das durch die Transmission der Maschine gedreht wird.ι is the adjustable at different angles, 2 rotatable frames in the machine attachment. The axis 3 of the reel is in one of the two on the frame 1 sliding sleeves 4, 4 mounted. The axis 3 goes through the top of the four Legs 6 existing parallelogram forming sleeve 5. The center of the lower The parallelogram tip lies in the center axis of the frame part mounted in the attachment 2. Small chain wheels 8 are arranged at the four tips of the parallelogram, around which a common chain 9 is guided. The top sprocket sits on top of the Hub of the reel, the lower sprocket 8, however, is connected to a helical gear 10, which receives its drive from a screw 11, which is driven by the transmission the machine is rotated.

Claims

stretching the parallelogram causes. Around ! to enable this and at the same time to be able to determine the reel in the set position, the device described below has been made. At one tip of the parallelogram 6, a rod 12 is rotatably arranged, which is provided with thread over a small part of its length. This threaded part is surrounded by a nut 13 which is rotatably suspended in one of the parallelogram legs. The end of the rod 12 located outside the parallelogram is connected to the rod 18 by means of a joint that works in a manner similar to a universal joint. The hinge consists essentially of a curved fitting 14 which receives the bent, threaded ends of the rods 18 and 12. The fitting 14 is cylindrical and its axis is a quarter of a circle. The rods 18 and 12 are in a common plane. Only their bent ends do not remain in this plane. The small displacements that have to take place during the movements of the swivel joint are made possible by the fact that the thread of the parts screwed into one another is given some leeway, and that the rods 18 respectively. Turn 12 alternately to one side and to the other side by a small amount in the thread of the fitting piece 14. This arrangement enables the rotation of the rod 12 to be brought about by that of the rod 18 without the interposition of a universal joint. The end of the rod 18 is provided with a strong, flat thread and passes through the smooth bore of the carrier 15 fastened on the crosspiece 16 of the machine. It also carries a crank 17 provided with a nut thread. The crank 17 is held in its position in relation to the support 15 by means of a screw which can slide in a groove located on this support. In the threaded part of the rod 18, a groove 19 of a certain length is cut into which a bolt movably arranged on the crank 17 is cut. 20 can snap into place. . Fig. 3 shows the position which the rods. 18 and 12 take after at. With the latch 20 snapped in, the rod 18 has been rotated by 900. FIG. 5 shows the position of these rods after they have been rotated by 180 °, the position of FIG. 1 always being decisive as the starting point of the movement. FIG. 4 shows a view of the swivel joint projected from left to right onto a plane perpendicular to the plane of FIG. 1. 6 is a plan view of the rods 12 and 18 occupying the position of FIG from the groove 19 and then rotates the crank 17. There is then no rotation of the rod 18, but only a movement of the same in the longitudinal direction, so that the setting of the frame 1 can be made at the desired angle. If, on the other hand, the parallelogram is to be extended or contracted, the bolt 20 is allowed to enter the groove 19, whereupon the crank 17 is turned, which also sets the rods 18 and 12 in rotation, but without displacement in the longitudinal direction. The nut 13 then travels under the influence of the rotating rod 12 on the threaded portion of that rod, thereby stretching or contracting the parallelogram. Godfather ν τ-Α ν Proverbs:
