Abstract: 457,339. Coin- and manual - freed article-delivery apparatus. NICHAMIN, A. J., 46, Byron Avenue, South Woodford, London. May 30, 1935, No. 15718. [Class 18] [See also Group XVIII] In apparatus for delivering articles in succession, a column <1> of articles is supported on a lift or carriage 2 which is raised after each delivery operation, and feelers 52 are provided which initially yield to the rising column and subsequently are checked to position the topmost article for ejection. Upon closing a switch, either manually or by coin-freed mechanism, the core of a solenoid 21 is pulled up and through a lever 29 and gear wheels 31, 32, a #- shaped ejector 18 is swung round to eject the topmost article on to a platform 45. The up-and-down movement of the core of the solenoid is limited by a buffer 73 and a spring (not shown). A chain and cable 41 connected to the lift 2 is also connected to a drum on a spring motor 33 so that the lift is urged upwards, but this movement is checked by a detent 48 which engages a ratchet wheel 51 on the shaft of a pinion over which the chain 41 runs. The detent 48 is pivoted on a lever 49 which is spring-urged towards the ratchet wheel 51. The feelers 52 ride on the topmost article and when the ejector 18 is swung round to deliver that article, a stud 59 on an extension of the ejector arm is disengaged from a lug 58 on an arm connected to the feelers to free the latter, but a further lug 69 on the feeler arm is held up by a lug 57 on the lever 49 to prevent the feelers dropping on to the next article. During the resetting movement under gravity of the ejector, a spring-urged lever 64 pivoted on the arm 29 engages a cam surface 63 on lever 49 and pushes the latter outwards. This frees the ratchet 51 and allows the lift to be raised by the motor 33 during which time the feelers drop and lug 69 engages the end of nose 57 and prevents the lever 49 from swinging back. Re-engagement of lug 58 and stud 59 prevents the column and the feelers being raised more than one step. When the magazine is empty, an arm 75 on the lift 2 engages a plate 76 to stop the upward movement of the lift and a pivoted bow-shaped lever 71 is swung up to keep the ejector raised so that all parts will be freed to allow the lift to be pushed to the bottom of the magazine again for refilling. As the lift is pushed down, the spring motor is wound up. The front of the magazine comprises only narrow flanges on the side walls and it is open at the top, this opening being closed normally by the lever 71. The lift runs in a slot in the back of the magazine and carries rollers engaging both sides of the back wall. The feelers 52 have inturned edges at their upper ends which pass through slots in the sides of the magazine, and their downward movement is limited by engaging with the parts of the walls forming the lower edges of these slots. A bank of magazines can be connected so as to discharge, into one tray, and all the solenoids can be connected to a multiple button switch. According to the Provisional Specification, pivoted feelers are employed.
