Abstract

171,946. Haden, W. N., and Haden, C. I. April 26, 1921. Valves and valve apparatus, actuating. - Louvers, especially those employed in connection with the fresh-air inlets of radiators, are simultaneously operated by means of a bar 5 mounted adjacent to the pivoted edges of the louvers so as to be capable of endlong movement only, and formed with recesses to engage small projections 7 from those edges. These projections are preferably formed by bending a stout wire, as shown in Fig. 2, which may be prolonged at 16 to serve as the pivot of the louvers. The bar is connected to a lever 10 mounted on a bracket attached to the screen 13 of the radiator. The free edges of the louvers are formed as shown to overlap the pivoted edges of the adjoining louvers.
