SU20345A1 - Dial scales - Google Patents

Description

By means of the proposed dial weights, the balance sheet is intended to achieve an automatic indication of the exact weight of the substance to be weighed.

In the schematic drawing of FIG. 1 depicts the view of the weights without scales; FIG. 2-section along the line A - Bnafig. one; FIG. 3-frame with rack; FIG. 4 - a detail of scales without balance.

In box 1, having the form of a cylinder, on axes xaa and 66, resting at their ends, either in ball bearings arranged in the front and rear wall of box 1, or in a nest formed by three circles k, k, k (Fig. 4) , fixed in the front and rear walls of the box, two drums 2 and 2 are tightly seated. With each of the drums 2 and 2, the shoulders 3 and 3 of the dial arms are tightly tied in horizontal position, along which adjusting weights 4 and 4 can be moved, symmetrically fixed in one place or another shoulder using locking screws b and b, and in the vertical direction, the arms 5 and 5, along which can be moved and installed at a certain distance from the axis of the drums 2 and 2, weights 6 and b.

The drums 2 and 2 are wrapped with flexible ribbons 7 and 7 secured to them at one end so that the drums can be turned

at an angle of 90 ° and the other end to the top wall of the frame 8 (Fig. 3), one of the sides of which is a crestal M, coupled with the gear wheel W, the ends of which protrude out of the openings of the front and rear walls of box 1 and fitted with hands 9 on dials 10 and 10, mounted on them. Weights 6 and b at zero position of the arrow 9 on dial 10 are located vertically inside the box and slightly follow each other, but so. there is a gap between them that does not interfere with the rod 11 connected to the bottom wall of the frame 8, freely pass to the hole in the bottom: box 1 and then protrude outwards, where it ends with a ring 1.2 for hanging the cup or measure. In order to avoid swinging the rod 11 and the frame 8, on the sides of the one and the other are small rollers /) ,,. To hang the scale, a ring 13 is used, which passes through pin e attached to the top of box 1. If the cup is hung from ring 12 ,. so that the restoration of equilibrium is necessary to move cargo 4 and 4 along shoulders 3 and 3, if possible, at equal distances from axes aa and bb of drums 2 and 2. After this installation, all the load placed on a cup or a measure, through rod IV ,.

the frame 8 and the flexible belts 7 and 7 will rotate the reels 2 and 2; the latter are rotated at one angle or another, and then the creamer M lowers and rotates the gear wheel W, and hence the " hands 9 and 9 on the dials 10 and 10.

The subject of the patent.

Dial scales-bezmen, characterized by the use of two dial rocker arms (quadrants) 3, 5 and 3, 5 with adjusting weights 4, b and 4, b being moved over their shoulders, having the form of drums 2 and 2 attached to them with flexible ribbons 7 and 7, connected to the frame 8, carrying on one side the cremalis M linked to the gear wheel W with the arrows 9 and 9 mounted on its axis.
