FRANZ BÖGERSHAUSEN in VECHTA i. Oldbg.

Patented in the German Empire on October 3, 1906.

Watering devices for grazing cattle, in which the cattle are fed by stepping on a walkway the drinking water itself raises are known.

The novelty consists in the device to determine the weight of the cattle by the fact that the raised water is not driven into the drinking bowl, but into a riser pipe is, with another device on the walkway that one for different heavy animals can receive appropriate leverage. The device is shown in Figs. I, 2 and 3 of the drawing.

The suction pump α, which lifts the water, is operated by a two-armed lever b , which is mounted in point c and is rotatably connected on one side to the piston rod and on the other side to the walkway d. The walkway d rotates around the point e and is balanced by counterweights so that its position in the unloaded state corresponds to FIG. As soon as the walkway descends, the pump piston rises and brings a certain amount of water with it, which enters a pipe g and flows from here into the drinking container h , in order to be enjoyed by the cattle.

The use of this device for weighing the animals is activated by switching on

\ of the three-way tap i in the pipe g , in that it prevents the water from flowing away to the drinking container when it is in the appropriate position and forcing it to enter the riser pipe k. If a head of cattle is led onto the walkway, so much water is lifted or pressed into the riser pipe until a state of equilibrium is reached between the water column on the one hand and the moment resulting from the product of the weight of the cattle and the distance from the center of gravity of the same Pivot point e of the walkway d results. Marks mm, η η, ο ο , etc., which indicate the point of view of the light, heavier and heavy cattle, are placed on the walkway at various distances from its pivot point. One end of a cord guided over pulleys is connected to a float, which rises and falls with the respective water level in the pipe k , and on the other end to a pointer, which shows the current level of the float on a scale. The pointer positions that correspond to the aforementioned weights are determined by loading with known weights on the various marks attached to the walkway. If the cattle are now placed on the markings on the walkway, the corresponding weight is indicated by the pointer on the scale. In the case of exceptionally heavy animals, the weighing is carried out in such a way that the animal is first placed on the outermost mark so that a full pump stroke enters the riser pipe. The animal then leaves the gangway and becomes after a while

for the second time on this in order to bring about a state of equilibrium and to be able to read off the full weight. Any adjustments according to the water level in the well are made by lengthening or shortening the arms of lever b . The door f is connected to the walkway by levers in such a way that it closes automatically when an animal has entered the walkway.

Claims (2)

Patent Claims: I. Drinking device for grazing cattle with a pump activated by the animal when entering a movably mounted crate, characterized in that a branch line to be connected to the pipe leading to the drinking trough by a three-way tap is provided with a riser pipe (k) for the purpose of to be able to determine the weight of the animal through the water level in the riser pipe. 2. Drinking device according to claim 1, characterized in that there are individual stamps on the movably mounted crate are arranged for the position of the animals, for the purpose of using different lever ratios for animals of different weights to be able to. 1 sheet of drawings.
