[Class 27] Clearing - apparatus, automatic.-In cointesting mechanism, such as used in coinfreed apparatus, wherein a coin shoot is provided with a pivoted side wall for releasing unsuitable coins which are retained therein by testing devices, the side wall is normally held in an open position by a loaded lever, said lever being movable to release and close the wall by the act of inserting a coin, means being applied to the lever to delay its return under the influence of the loading element, and thus to delay the automatic re-opening of the side wall. As shown, the side wall A is pivoted at 5 to the fixed part B of the shoot against which it tends to rest under its own weight. A bellcrank lever 12 pivoted at 11 is acted on by a spring 14 so as to hold the side wall in an open position by engagement with a projection 16 thereon. An inserted coin rocks the lever 12 by engagement with a part 17 so as to permit the side wall to close, and the means for delaying the return of the lever and side wall under the action of the spring 14 comprises a pendulum 18 pivoted at 19, and provided with rack teeth alternately engaging a pair of pawls 21 on the lower end of the lever.
