Abstract

3760. Winkler, G. G. F. C. Feb. 17. Pendulum-weight apparatus; indicating and registering mechanism. - Consists of an automaticaly-indicating apparatus in which equally increased movements of the pointer correspond to equal variations in the load. The load P, Fig. 2, is applied by means of levers or a flexible band to a quadrant E pivoted at 0 and having arms 0 A, 0 c, in a line with perpendicular radii O E, 0 D respectively. A pin c on the arm 0 c engages in a slot b, so that the movement of the arm 0 c causes a counterpoised bar s to slide vertically in its supports g, h, and a rack d and pinion e are thus caused to move a pointer over a scale S. The arm 0 A carries a weight p for balancing the load, and, when this arm swings through an angle x, it causes a vertical movement of the rack d equal to R<1>.r.P/p.R where R<1>, r, R are the radii 0 c, 0 D, 0 A, respectively, and, since these three quantities are constant, the movement of the rack and its pointer vary as the load P. An additional pointer l and scale m may be employed, each division of the scale m indicating, preferably, the weight corresponding to a complete revolution of the other pointer. A modification is described in which the arm 0 c is in a line with the arm 0 A, the rod s then being horizontal, while the additional scale is dispensed with.
