Abstract
369,138. Changing signs. EHRENZWEIG, A., 21, Rotbuchstrasse, Zurich, Switzerland. Aug. 14, 1931, No. 22954. Convention date, Aug. 14, 1930. [Class 3 (i).] A single or double-sided mirror is oscillated by a continuously rotating driving member so as to reflect two display members alternately to the same view point. Fig. 1 shows a pivoted mirror 15 oscillated from a position in which it reflects to the right hand a transparency 16 to a position in which it similarly reflects a display member 24. A wind motor 9 drives the mirror through worm gearing 11, 12 and either a single link 14 or two links and a bellcrank. To obtain a longer period of rest in the display positions the modification shown in Fig. 3 may be adopted. A rotating crank pin 25 engages a slot 27, 28 in a member 26 sliding between guides 31, the member 26 being connected by a link 29 to the mirror 15. The mirror remains stationary while the pin 25 is traversing the curves 27 of the slot. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the substitution of the mirror by a display panel. This subject-matter does not appear in the Specification as accepted.
