Abstract: 465,243. Coin-freed article delivery apparatus. NATIONALE TELEPHON-UND TELEGRAPHENWERKE GES. Aug. 27, 1936, No. 23583. Convention date, Sept. 4, 1935. [Class 27] In a coin-freed vending-machine having a coin-operated mechanism common to a set of compartments and comprising a bar which is freed to be moved to allow the compartments to be opened when the appropriate coin or coins have been inserted, a rigid bar or rail is also provided which is displaced when a compartment is opened and brings a series of locking members into position to lock the remaining compartments. The compartments may each contain a single article and be closed by a door, or each compartment may contain a series of articles which are delivered one at a time by pulling out a drawer instead of by opening a door. In the application to a machine having compartments closed by hinged doors, each door T, Fig. 2, hinged at A has a quadrant U bearing against a pin B on a slide J, thus holding the door closed against the action of a spring P. After insertion of coins, the slide J of a selected compartment is pushed in by a button D thereby moving the pin B from underneath the quadrant which rocks downwardly, the door moving upwardly. The slide is held in its pushed-in position by the pin B engaging the curved surface of the quadrant, until the door is again closed. A rigid bar S2 has pins T2 projecting through slots 02 in the slides. An inclined edge of the slot of the pushed-in slide engages its pin T2 and moves the bar S2 so that the other pins T2 prevent any of the other slides from being actuated. The pin T2 of a fully actuated slide engages an extension O of the slot 02, and the pins T2 are so arranged that only one pin can engage an extension O. Instead of the button D being integral with its slide J, it may be connected thereto through a spring so as to prevent damage should force be used. The side walls of the compartments are provided with windows through which a lamp illuminates the contents. Coin action, mechanical - connection and multiple-coin.-The slides J are normally locked by a bar S1 having pins T1 engaging V-shaped slots 01 therein. When a slide is actuated, the bar S1 is moved up, this movement, in the absence of coins, being prevented by a projection Y on the bar engaging a stop y on a lever 8 pivoted at 7 and controlled by a spring 9. A notch X on the bar S1 engages a pin x on a coin holder H pivoted at C. As shown a pin 21 is positioned in the holder so that four coins are required to fill it and free the apparatus, these coins, after passing through a testing mechanism, being delivered to the holder by a shoot 14. The holder is rocked by the upward movement of the bar S caused by pushing in a slide J and the end coin engages a pin 11 on the lever 8 and rocks this lever to withdraw the stop y from the path of the projection Y. By placing the pin 21 in different positions, the holder H may be adjusted to take different numbers of coins. Coin-discharging mechanism.-The coins are retained in the holder H by a projection 19 on a lever 16, until a door is opened, whereupon a quadrant V engages a pin T3 on a third bar S3 and depresses this bar to depress the lever 16 and allow the coins to roll out to a shoot K leading to a money-box. Returning coin.-The pin 21 is connected to the end of a lever 12 which can be actuated by the control rod of. a knob R to allow the coins to roll to a return shoot RS, if this knob is pushed in before an attempt is made to open a door.
