Title:
PAN BALANCE FOR ANALYSIS
Document Type and Number:
Japanese Patent JPS6071918
Kind Code:
A
Abstract:
In an analytical balance with a pan and a four-bar mechanism which keeps the balance pan parallel horizontally during its vertical travel, the one vertical side of which is held fast to the housing, the other vertical side of which, in the form of a coupling piece, carries an extension which receives the pan, and both horizontal sides of which are connected in an articulated manner by an upper and a lower rod to the vertical sides, whereby the four-bar mechanism is loaded by the restoring force of a load converter, the extension (16) which receives the pan (17) is L-shaped, the horizontal L-shank (pan arm) (16'') carries the pan (17) rigidly connected to its free end and the vertical L-shank (bearing arm) (16') is mounted on the bar (18''') of a U-shaped arm bearing (18) which projects above and below over the vertically movable end (9) of the four-bar mechanism (5, 6, 7, 8, 9) with its two horizontal U-shanks (18, 18'') in the rod planes and is rigidly fastened to it in two vertically superposed bearings (118'). Such a construction avoids the introduction of damaging torques from the extension (16) and the balance pan (17) into the sensitive parallel guide (5, 6, 7, 8, 9).
