Abstract
352,750. Lift-gate fastenings. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Schindler & Co. ; 2, Sentimattstrasse, Lucerne, Switzerland.) July 24, 1930, No. 22328. [Class 78 (iii).] The locking member b of a lift well gate mechanism is prevented from turning with the unlocking lever e by arranging that the direction of the force P exerted by a control lever a on the lever e passes through or below a fixed pivot D. When the control gear is operated, the lever a is rocked over by a shaft rod G, and a member b with which the lever a engages by a pin-and-cam connection n, c, is brought into the position shown in Fig. 2 to look the bolt R The lever e is rocked about its pivot d on member b by a spring f. On the control gear being disengaged the lever a returns to its original position Fig. 3, and throws over lever e with which it engages by a pin and cam connection i, k. The force P being directed through or below the pivot D, member b remains in its locking position until lever e connects with a ramp A on the cage. In a modification, Figs. 5 and 7, levers a, b have fixed fulcrums d<1>, d2, and a two-armed unlocking lever e is pivoted at d<3> on an arm a<1> of the lever a. One end of the lever e supports a roller h which bears against the cage ramp A during the unlocking action. The other end carries a pin n engaging with a guide slot K. The centre line M<1>, M<2> of the slot passes below the pivot d<1> to prevent member b turning with the lever e.
