Weighing-apparatus; coin-slit closing-devices.- A coin slot closure for a coin-controlled ticket printing and delivering weighing scale, and as shown applied to a ticket printing scale of the kind described in Specification 257,331. comprises a T-shaped shutter 26, Fig. 6, pivoted at 28, the depending leg 34 of which normally closes the coin slot 38. When a person steps on the platform of the scale, a lever 3, Fig. 2, is rocked by a rod 1, thereby raising a rod 8, a collar 14 on which, under the action of a spring 10, raises an arm 18 pivoted at 19. The arm 18 raises one, end of a second arm 20 at right angles thereto, depressing its other end 24 which passes through a slot 25 in the shutter and moves this to uncover the coin slot. A coin is now inserted and trips mechanism which sets in operation ticket printing and ejecting mechanism and includes a weighted lever 49. The weighted end 50 of this lever drops and depresses a rod 53 passing through the arm 20 and being surrounded by a coiled spring 54. This spring is compressed by a nut on the rod and depresses the arms 20, 18, thereby closing the shutter while the person is still on the platform. If a person steps on and off the platform without inserting a coin, sufficient play is left between the lever 3 and a shoulder 62 of a latch 59 that is operated by the coin tripped mechanism, to allow the lever 3 to return and the shutter to be closed. When the tickets stored as described in Specification 257,331 in an upwardly moving magazine are nearly exhausted. the magazine rocks an arm connected by a rod 63 to the arm 20 which is thereby rocked and holds the shutter closed.
