Description

The foregoing invention relates to weights and cocTOHSr in their particular constructive implementation.

In FIG. 1 is a front view of a scale; FIG. 2 is a side view and FIG. 3-separate detail.

In addition to the crankshaft 4.17 with a constant load 5 on the shoulder 17, fastened to the upper prism 5, resting on the pillows 5 in the floods 1, in the same tides on the prism 5 there is a second rocker 8, with the support of the latter V lying below points of support of the first rocker. One shoulder of the rocker arm 8 is connected to the stem of the cup 18; serving to receive weights, balancing additional weight on weight cup 6, The other arm of this rocker arm is connected to rod 7 weight cup 6, and in addition, with steel flexible tape 10 wound on roller 11. Roller 11 sits on the same axis with the rollers 11 of larger diameter, wrapped around with steel flexible ribbons 18, having f3 pointers attached to them, moving along the weights of the horizontal scales located on the sides of the base. The other ends of the belt are wound on rollers 12 located on the other side of the scales, which sit on the same axis with a roller of smaller diameter, 12 meters with a load 14 suspended from it. On the load b, an additional load 9 is suspended on the rod, equipped with screwed cutting as a regulator

to obtain, with the appropriate installation of uniform divisions on the horizontal scale of the balance. In addition, a damper rod i6 is attached to the shoulder of the rocker arm 8, which is intended to stop the pointers 5 more quickly.

With a certain load on the cup & the vertical lever 7 presses on the shoulder 4 and on the yoke 8, which causes the moving of the load 5, which serves as a counterweight and the regulator 9; in turn, the rocker B transmits the movement of the steel flexible tape 18 winding around the rollers 11 and 12. The reverse movement of the belt 18, with the pointer 13, takes place due to the load 14 suspended on the roller 14. The working angle of the rocker arm 8 is approximately 30 °; The quince legs at equilibrium should be equal and this is done by a load 9, which, respectively, is located, moves the center of the weight of the load 5 to the left and equalizes the load of the shoulder c.

With the help of the weights of the proposed design, it is intended to produce a quick weighing of the goods, while observing the weights is very easy.

Subjectpipept

1. Scales, characterized by the use of, in addition to the crank arm 4.17 with a constant load 5 on the shoulder 17, another rocker 8, the fulcrum of which lies below the fulcrum of the balance arm 4.17 and one arm of which is connected to the rod

cups 15, used to receive weights, balancing additional weight on weight cup 6, and the other shoulder, besides connecting with rod 7 of weight cup 6, is crossed with steel flexible tape 10 wound on roller 11, which sits on the same axis with larger rollers diameter, wrapped in steel flexible tapes in, having pointers attached to them 13, movable along located but. to the sides of the bed scales horizontal

scales, the other ends of which bands 18 are wound on rollers 12 arranged on the other side of the scales, which sit on the same axis with a roller of smaller diameter IS with one, a weight 14 to it.

2. In characterized in n. 1 scale is used when the load is 5 additional weight 9 sitting on a rod equipped with a screw thread and serving to obtain uniform graduation on the horizontal scale of scales in accordance with its installation.
