Abstract

382,220. Balancing devices. POITEVIN, H. J. P., 30 bis, Boulevard Jourdan, Paris. April 21, 1932, No. 11464. Convention date, April 24, 1931. [Class 78 (ii).] A sliding body, such as a window, which exerts a constant force is balanced by a device comprising a lever c acted on by a force through a point A on a line through the pivot o parallel to the direction of the constant force and proportional to the distance between the point A and the point M of application on the lever. The balancing force is exerted by springs f and a cable g, and when the lever c is parallel to the direction of the forces due to the weight of the body, the distance AM is equal to the extension of the springs.
