Description

In the proposed automatic scales for fluid bodies, with the use of a bucket suspended from the rocker, in the latter there is a float that covers the stem of the outlet valve of the bucket. The said rod is associated with a crank lever, provided with a toggle weight and acting with a free end on the lever connected by a ratchet mechanism to the lever inlet valve, which can only be opened after the bucket is completely empty, when the end of the exhaust valve stem rests on the crossbar under the bucket.

In the drawing, Fig. 2, a vertical section of an automatic balance for liquid bodies is shown.

On one arm a bucket is suspended in and on the other side a load is balanced on it 6. A bracket is attached to the bucket, on which a cranked lever with a transfer weight is placed on the hinge X. The lever knee is connected to the knee e by means of two pylorus-shaped stops w, sitting on the rod. The top stop is stationary, and the bottom is pressed to the lever with a spring h. A float is placed on the valve stem e in the bucket, which pops up when the bucket is filled with liquid and lowers under the action of its own weight while releasing its black valve from the bucket. Ladle

during weighing, it does not go beyond the limits of the tank to, across which is placed the crossbar.

After a weight is added to the load, corresponding to the weight of the fluid to be weighed, the transfer weight is brought from the rightmost position // shown by the dotted line to the position / than the inlet valve e of the bucket is closed, and at the same time the end of the lever t presses the lever n and the last equipped with a ratchet device, opens with a lever with an inlet valve in a tank filled with liquid, which is poured into the bucket through a drain pipe. As the bucket is filled with liquid, it pushes the load on the other arm of the rocker arm, and the balance wheel /, falling over to the side of the pivot arm, contributes to lowering the bucket. The lever nj slides off the lever n, as a result of which the inlet valve m closes. When the bucket is lowered, the outlet valve rod e abuts against the crossbar l and opens the valve e, at the same time moving the lever with the load g to its original position //. The liquid begins to pour out of the bucket and, as it is poured out, the left shoulder of the rocker arm rises along with the bucket. At the same time, the bucket lifts the end of the clamp m to rest on the end of the lever, but due to the ratchet mechanism the valves m remain closed and the lever t.

noflHH asr lever n, at the end of movement cKpflbsViT at the end of the latter. When all the liquid is poured out of the bucket, the float sits on the valve e and closes the latter with its weight, simultaneously transferring the load g to the left position /, and the whole process of the balance starts again.

The subject matter of the invention.

/ Automatic scales for liquid bodies with the use of a bucket suspended from the rocker,

The purpose of controlling the inlet and exhaust valve is a device consisting of a float located in the weighing ladle, covering the outlet valve stem e, hinged articulated with transfer weight d, and on the periphery of the free end of the lever t of this load is located a lever n connected by a ratchet mechanism with the intake valve lever m, in order to open the latter only after the emptying of the shaft, caused by lowering the bucket by pressing the end of the exhaust valve stem on the crossbar l.
