Description

In the proposed dial weights for automatic adjustment of one quadrant to the determination of the weight of small and large loads by the dial, the counterbalance arm of the quadrant is equipped with a number of prisms or slots that lift free hanging weights in order to gradually increase the weight of the counterweight.

When performing weights in a vice of two quadrants, the latter are connected with the weights of the weights, or steel flexible bands, respectively suspended on prisms or attached to the fists, which prisms and fists are located on the short arms of the quadrant arms.

In FIG. 1 is a side view of a single quadrant dial with prisms; FIG. 2 is the same with sockets; FIG. 3 is the same, with two quadrants connected by an earring; FIG. 4 - the same, connected by flexible tapes; FIG. 5-cross section of the box.

The long counterbalance arm of quadrant 9 is equipped with a series of prisms 10 (Fig. 1) or sockets 29 (Fig. 2), which, when the scales are loaded on a load of 14, automatically pick up the weights that hang freely in the slots of the box 1 to gradually increase the weight of the counterweight. surrounding the shoulder of the quadrant (Fig. 5).

Quadrant 9 is associated with an arrow 19 indicating the weight on the dial 18.

When performing dial weights in the form of two quadrants 9, the latter are connected with. th 14 scales by means of earrings 13 (Fig. 3), suspended on prisms located on the short arms of quadrants; to earrings 13 with hooks, a ha of 14 weights is provided, fitted on top with two strips 15 with slots b through which the axis of the arrow 19 passes with a gear connected to a vertical rack mounted between the strips 15. The quadrants are enclosed in a box 1 with a lid 2 (Fig . five); In the side walls of the box 1, there are cut-out slots 3 for suspending in them a number of weights 11 on the trunnions 16. The quadrants are provided with axial prisms 12 supported on pillows 5 mounted in the side walls of the box 1, which is fixed on the front of the scale.

The connection of two quadrants with a pull can also be made by means of steel flexible bands 24 (Fig. 4) attached at one end to t 14 and the other ends to fists 22 on the short arms of the quadrants swinging on ball bearings 25.

Calipers 18 with arrows 19 are attached on both sides of cover 2 of box 1.

Under the weight of the load placed on the scales, the gi 14, the latter is also lowered using the earrings 13, or flexible belts 24, turns quadrants 9, whose long arm with prisms 10 or notches, 29, successively lifts weights 20.21 and others. 17 of them, gradually increasing the weight of the counterweight until it reaches the weight corresponding to the weight being weighed, and the balance will come to equilibrium, with this, the ha 14 will rise and turn the gear 19 by means of the rack and gear to the corresponding division of the dial.

The subject matter of the invention.

Claims (2)

1. Dial scales, characterized in that in order to automatically adaptations of one quadrant to the division of the weight of large and large loads on the dial 18, the counterbalanced square of the 9th quadrant is equipped with a number of prize 10 or slots 29 (Figs. 1 and 2), intended for picking up, while increasing the load on the scales freely sk from weights 20, 21, etc., in a box of 1, gradually increasing in such a way: the mass of the counterweight. 2. The form of execution of dial weights according to claim 1, characterized in that they are made in the form of two quadrants 5 associated with a gravity of 14 weights or 13, suspended from prisms, on quadrants walking on the short arms (Fig. 3), or steel flexible ribbons 24, attached to the respective fists on the short arms of the quadrant arms (Fig. 4).   V ..- pf "YAG l-lf: ft-4 TfTf-n  ,, fff t | 1H - Sch YU F; ,, “- iff - 1 I ..
