Abstract

1426372 Coin-operated locks SCHULTESCHLAGBAUM AG 1 Aug 1973 [5 Aug 1972] 36547/73 Heading G4V A lock comprises a locking mechanism made operable by the insertion of a locking coin 18 after which a locking member 10 is movable to a locking position, the coin being temporarily retained in a pocket 17 in the locking member and being released therefrom under the control of a timing mechanism 37. In the embodiment described which is associated with a rental locker a timing coin 43 must first be inserted via slot 42 into a pocket 41 of the timing mechanism, movement of the coin into the position shown in Fig. 2 rotating a control finger 37 of the timing mechanism anticlockwise to move a slide 23 from a normally retracted position (Fig. 1, not shown) to beneath the coin pocket 17 where it is held by a catch 32. A locking coin now inserted via slot 19 is retained in the pocket 17 and on rotation of a lug 8 by means of a removable key the bolt 10 may be moved to a locking position, Fig. 4, the coin 18 lifting a pawl 21 to permit full movement of the bolt. On movement of the bolt a lug 60 on a lever 52 pivoted to the bolt shifts from a position blocking pocket 41 to allow the timing coin to fall to a collection shoot 45 via an opening 23<SP>111</SP> in the slide 23. At the expiration of the time period set by the timing mechanism the finger 37 moves back to its initial position to release catch 32 and allow the slide 23 to be retracted by spring 26, the coin 18 falling from pocket 17 into a collection shoot 46 (Fig. 5, not shown). Before the end of the set time period the rental locker may be unlocked and relocked without loss of the coin 18 or the insertion of a further coin 43, and if a coin return button 47<SP>1</SP> is depressed, with the bolt 10 in its retracted position, lever 52 is pivoted so that a finger 57 thereof engages a part 50 of the timing mechanism to reset it, hence withdrawing slide 23 and allowing the coin 18 to fall to a coin return shoot 44. If the button 47<SP>1</SP> is depressed before the bolt 10 has been moved to its locking position the timing coin 43 is guided by the lever 52 so that it also falls to the coin return shoot 44 (Fig. 3, not shown).
