Claims (1)

The present invention relates to a powder gun for oral application to animals, especially cattle and horses, with a filling tube in which a piston counteracts the effect by means of a handle arranged on the end of the piston a spring can be moved inward from the open end of the filling tube into a lockable position, the open end of the filling tube with the piston outside a receptacle for a powdery Forms drug, with a locking element that releases the piston when actuated against spring force to empty the amount of powder in the receptacle to the outside. A pistol is already known to give horses and other animals medication in pill form »5 admit. This device consists of a filling tube, in which a piston by means of an end, arranged on the piston handle against the action of a spring in a lockable position from to move the open end of the filling tube inwards is bar, the open end of the filling tube with the piston outside a receptacle for a drug forms. In the known device, the trigger for the pistol is exposed on the front Arranged at the end of the filling tube (German Patent 21 096). It is well known to have such a device without using a drive spring only as a cylinder train in which a piston is manually displaceable to the animal remedies or food to be introduced through the mouth (German patent specification 476 354). When working with spring force devices, it is already known, the actuator for the Train the pistol as a trigger in conjunction with a pistol handle, which makes the filling tube light can be handled and the risk of accidentally triggering the trigger is reduced (British Patent 651524 and U.S. Patent Document 3 238 941). The latter devices allow easy handling of the filling tube, but are relatively complex with regard to the structure of the pistol grip. The invention is based on the object Extraction device for the powder pistol, d. H. to further simplify the training of the Spcrrelement. According to the invention, this object is achieved in that the locking element consists of a flat locking slide consists, which is arranged in diametrically opposed grooves of the filler tube and which engages in a notch in the piston rod and can be released by radial actuation pressure. The inventive training is a very simple pistol cover obtained, with which there is also the risk of accidentally pulling the trigger, as is the case with a pistol with a cm on the end face Deduction, is minimal. The invention will then be described on the basis of an exemplary embodiment in conjunction with the drawing. I ^! .s shows Fig. I is a side view of the invention Powder pistol, F i g. 2 shows a view of the individual parts of the powder gun and F i g. 3 is a view of the pistol in the fully cocked state, The powder gun consists of a preferably metallic filling tube 1 in which a piston rod is movably arranged, which carries a piston 2 at its end, which is preferably screwed to the piston rod with the interposition of a plastic disk 17. When the pistol is not loaded, the end of the piston is at the open end of the filling tube, which is preferably provided with a protective hose 18 made of plastic. The other end of the piston is equipped with a handle 15 which is screwed to the piston rod with the interposition of a rubber buffer 16. If the handle 15 is pulled outward while a spring 3 located on the piston rod is tensioned, the piston and the sleeve wall form a receptacle, the size of which is preferably adjustable in several stages to accommodate different amounts of powder. The individual stages are set by metering notches 9, 10 and 11 on the piston rod, each of which can be brought into engagement with a locking slide 5, which engages in grooves 7 and 8 arranged diametrically on the filling tube and automatically engages the metering grooves by a spring 6 is brought. Using 50 ¹ OIgCn Thibenzole-Pulvcrn obtained for the stages 1, 2 and 3, quantities of about 20 and 50 g. On the piston rod there are further notches 12, 13 and 14 arranged at a distance from one another arranged, which allow different levels of tension of the spring 3.
