Abstract
373,862. Retractive switches ; retarding action of switches. GROHN, W., 18, Miltenberger Wes. Pankow, Berlin. Aug. 19, 1931, No. 23337. Convention date, Aug. 19, 1930. [Class 38 (v).] A switch for direction indicators has two or more operating levers a, b which can be moved against the action of retractive springs into engagement with contacts such as m, n, o; the levers return slowly when released, the delay being caused by clockwork and ratchet mechanism that is common to the two levers. In the form shown in Figs. 2 and 3, the lever a, which can be moved in opposite directions i n t o engagement with a contact m or n is pivoted at e and the lever h which can move ir one direction only into engagemenwith a contact o, is pivoted at d and has an arm b<1>. A lever l is also pivoted at d. Operation of the lever b or of a lever a up or down causes the engagement with a member f<1> of the arm b<1> or the arm a or the lever l respectively, the lever l being driven in a clockwise direction by a stud k on the lever a when the lever a is moved down. The member f<1> forms part of a member f which is pivoted at d and carries a latch 8 engaging a ratchet wheel h connected to a wheel z and chain gearing r. The latch slips over the ratchet wheel during operation of the lever a or b, but when the lever is released and a retractive spring acting on the member f<1> returns it and the lever, the latch engages the ratchet wheel and drives it and the braking gearing r. In a modification, Fig. 5, the arms a, b can both be moved in both directions and each of them has fixed to it a member q which lies between two levers x, y pivoted at d. The ratchet wheel h connected to the braking gearing is also engaged by two pawls g<1>, g<11> pivoted on the levers y, x. Operation of either lever a, b in either direction causes a member q to actuate a lever x or y and cause its pawl gll or g<1> to slip over the ratchet wheel and at the end of the stroke the top end of the lever z or y depresses a longitudinally-moving member u and causes this to release the other pawl g<1> or g<11> so that when the lever a or b is released the parts return under the action of the braking train.
