SU14274A1 - Gravity Scales - Google Patents

Description

The proposed gravity scales are designed to observe changes in gravity voltage over time.

In FIG. 1 is a front view of a scale; FIG. 2 is the same side view; , figs. 3 - top view of the balance beam; FIG. 4-part attachment of the suspension springs of the yoke, front view; FIG. 5- Same, side view.

The device of the proposed gravity weights is as follows. In the upper part 3 of the base 1 (Fig. 1 and 2), equipped with three adjusting screws 2, the supports 4 are fixed, supporting the crossbar 5, to which, by means of the leaf spring 7, the rocker b is lit. The end of the spring 7 (Fig. 4) is clamped between the middle 8 and right 9 parts of the rocker b, and between the middle 8 and left 11 parts of the rocker b reinforced plate spring 10 connected to the spring system 12 (Fig. 1 and 2), which can be formed, for example, a set of plate springs assembled in a zigzag manner, or it consists of spring boxes of the type baro-cheteric boxes Vidi, the inner space of which is connected to the outer space by corresponding openings. The lower end of the spring system 12 using

leaf spring 13 is attached to the base 1 of the device. Parts 8, 9 and 11 of the cowhide are bolted 14 (figs. 3 and 5), the ends of which are released from the rocker arm. On the left side of the bolts 14 can be suspended balancing weight (counterweight) 15, on the right side of them. a working load 16 is suspended, attached to the bolts by means of a sliding holder 17, connected by a micrometer SCREW to the fixed holder 19 (Fig. 3). The load 16 is attached to the holder 17 by means of a leaf spring 20. For reading the weights, there is a pointer 21 (Fig. 1 and 2) attached to the rocker b, and a scale 22 mounted on the base 1 of the device. In addition to the TOR, base 1 is set a plate 23 serving as a black background for a polished ball 24 fixed on the pointer 21 and serving as an artificial light point in photographic recording of the weight readings. In order for photographic recording to be carried out on the wrong side of the device, on which visual observations are made, a slot 25 is made at the base 1 (Fig. 1). 5 The same cut was made for the passage of the pointer 21 through the horizontal part 26 of the base. The entire instrument is placed in a bronze cup 27 and covered with a glass bell 28 lapped to a cup. Under the bell 28, the air is thinned to a pressure below the lowest that can be at a given point on the earth's surface, ..

The subject of the patent.

1. Gravity scales, characterized by the fact that their yoke is suspended from the crossbar 5 racks 4, enclosed together with the base 1, 2, 3 under the bell, under which air can be discharged, using a plate spring 7, sandwiched between the middle 8 and one of the extreme 9 parts of the rocker b, between the other extreme part 11 of which and its middle part 8 is clamped the Plastin spring 10, connected to the spring system 12, the lower end of the "recess" attached by means of the leaf spring 13 is attached to the base of the spribor, which parts 8, 9 and 11 rocker b st chickpeas bolts 14, the ends of which rocker 1puscheny and bear on one side a counterweight 15, and on the other side - the working load 16 suspended by a spring 20 to the movable, by means of a micrometer screw 18, yokes 17.

2, In the application of gravitational scales described in paragraph 1, for

the reading of their testimony, attached to the yoke b pointer 21 and strengthened on the basis of the device scale 22.

3.B described in pp. 1 and 2, gravitational scales use polished i24 ball polished on pointer 21, serving as its artificial light point for photographic recording of scales readings, and fixed on the base of the plate 23, which serves as a black background for the ball 24
