PCT No. PCT/CH79/00085 Sec. 371 Date: Mar. 17, 1980 Sec. 102e Date: Mar. 17, 1980 PCT Filed: Jun. 7, 1979 Pub. No. WO80/00245 Pub. Date: Feb. 21, 1980. Field of the invention: filling machine industry. Device consisting of a lever made up of two arms arranged on each side of a fixed pivoting axis. The end of the first arm supports the end of a rod, movable axially and vertically to rotate the arm and ending at the other end in a load-carrying platform moving downwards as the load increases. The end of the second arm, consisting of two parts pivoting about a movable axis, carries a counter-weight and by sliding along the pivoting part on a fixed axis may itself slide along a straight inclinable rail. By suitable selection of both the weight of the counter-weight and the slope of the straight rail, the lever is balanced at the same time in two positions, one corresponding to zero load on the platform and the other to a predetermined load placed on the platform, there being substantial equilibrium in intermediate positions. Use: Metering of bulk products discharged into containers by filling machines. |
