Description

The proposed scales are designed to control the correctness of the weighing of loads, regardless of the accuracy of the weights used, for which they are supplied with a coil spring or balances that are compressed by the action of the load (placed on the scale pan) and the scale on which the weight of the load is determined in parallel.

FIG. 1 shows the front view of the scales, with the rack shown in section; in fig. 2 shows a front view of a rack with a pointer; in fig. 3, the modification of weights with the use of balances and in FIG. 4 side view of this change.

The balance beam 1 (Fig. 1) of the balance is supported by a rod 2, which is movably inserted into a hollow cylindrical rack 5, inside which the rod rests on the spiral spring 4. Outside the rack (Fig. 2) there is a scale 6, graduated according to the elasticity of the spiral spring 4, with A pointer 7, attached to rod 2, moves in a vertical notch in the rack against the scale, marking on the scale the total weight of the load placed on the scales. Instead of an ordinary equilibrium arrow, two arrows, 5, 5, attached to the yoke on the sides of the reference prism, are used, making it possible to judge the balance of weights. Thus, on the one hand, the weight of the weighed cargo is judged by the weights, and on the other hand, the correctness of this weighing on a scale of 6 is monitored using the pointer 7.

FIG. Figures 3 and 4 depict a modification of the proposed weights, consisting in that the spiral spring is replaced by a support bar 8 supporting the rod 2 against a hollow pole 3 sliding in vertical cuts 3. The rod is supported on the rod 8 provided with prisms 9, 9 at the ends, pressing on the ends crank levers 10, 10, rotating on axles 11, 11 and fitted on the lower arms with weights 12, 12.

Under the action of the weights placed on the scales, the bar 2 produces pressure on the bar 5, which is transmitted by the levers 10, 10, the latter deflecting the weights 12, 12 until the pressure of the bar 2 is balanced. Pointer 7 (Fig. 4) attached to the bar 2 and sliding along the scale 6 along a vertical incision in the rack 3, marks the total weight of the goods placed on the scales, and thus makes it possible to check the correctness of weighing with the help of weights.

SUBJECT OF THE PATENT.

slot in rack 3 with pointer 7, moving against scale 6 attached to rack 3.

2. The form of execution of the weights described in p. 1, characterized in that in the hollow rack 3 weights a spring 4 is laid, which serves as a support for the movable rod 2,

3. The form of the implementation described in p. 1 of the balance, characterized with the use of cranked, equipped with counterweights 12, 12 levers 10, 10, serving as a support for the movable rod 2.

4. When characterized in ppt 1-3, the use of two arrows 5, 5 located on the sides of the support prism and associated with the rocker arm, to determine the equilibrium position.
