342,443. Coin - freed apparatus. GREENWALL, M., Long Copse, Bookham, Surrey. Dec. 3, 1929, No. 37037. [Class 27. ] Actuating and controlling mechanism.-In coincontrolled apparatus in which a movable control member connected operatively with a mechanism of the apparatus is moved by an independently movable operating member, both members being gravity or spring influenced independently to tend to return to neutral positions, the control member 11, Fig. 2, which is described in Specification 329,279, [Class 27, Coin-freed apparatus &c.], and is moved by an operating member 17 having a handle 18 and a lateral lug 16, Fig. 1, to engage a drive member 15 on the member 11, is provided with a notch 19 which is engaged by a tooth 22 on a detent 20, when the control member is in its operative position. The detent is pivoted at 21 and holds the control member in . its operative position long enough for the associated mechanism to be actuated, until it is raised through the engagement of its free end 24 by another lug 23 on the member 17 during the return of this member. The member 11 is then returned to neutral position by its spring. A full forward stroke of the member 17 from its neutral position is ensured by a pawl 26 engaging ratchet teeth 25 thereon, the pawl being pivoted on the same axis 21 as the detent 20 and having a pin 27 engaging a cam slot 28 in a plate 29. The plate 29 is mounted to rock on the axis of the control member, its movement being limited by a screw 39 passing through a slot 40 in the plate 29. A spring washer 41 compressed by a nut 42 provides a frictional resistance to its movement. Pins 32, 33 extend from the member 17 through actuate slots 30, 31 in the plate 29 so that, when the member 17 reaches the end of its forward movement, the pin 32 engages an end of the slot 30 and moves the plate 29 thereby moving the cam slot 28 to raise the pawl 26 out of engagement with the teeth 25. When the member 17 is returned to its neutral position, the pin 33 engages the end of the slot 31 to return the plate 29 and allow the pawl 26 to drop back to its initial position. The governing mechanism described is stated to be particularly applicable to the control and operating mechanism described in Specifications 321,870, 323,081 and 329,279, [all in Class 27, Coin-freed apparatus &c.].
