Abstract: 5227. Olsen, N. P., and Automatfabriken "Victoria" Aktieselskabet. Oct. 10, 1912. Sale apparatus.-The purchaser can select the article contained in any compartment 1 of a carrier C, which is adapted to be raised or lowered by an electric motor 7 under his control, so as to bring each horizontal row of compartments in turn behind a row of doors 11 through one of which (depending on the vertical column in which the particular compartment is situated) the selected article is withdrawn. Delivery mechanism.-After prepayment, the purchaser turns a handle 29, thereby moving a slide 19 to the left, Fig. 3, by means of a spring-controlled lever 30, and (a coin 36 being present) turning a lever 28 about its pivot 28<1> so as to raise a projection 38 above an extension 39 of a slide 18, which is thereupon moved to the left under the action of a spring 40 and is retained in this position by the engagement of the projection 38 with the extension 39. This movement of the slide 18 permits a spring contact 42 to close one gap .in the motor circuit, the other gap 41 being closed by a projection on the arm 31 of the lever 30 so long as the handle is held in the depressed position. A chain 4, Fig. 2, one end of which is attached to the carrier and the other to a counterweight 6 engages a chainwheel 5 driven by the motor 7 through gearing 9, 10. A switch 47, 47<a> (of known construction) reverses the direction of the current through the motor when the carrier is in either of its extreme positions, projections 50 on the carrier serving to reserve the switch arm 47<a>. Cords attached to the switch arm pass to the outside of the apparatus. The sliding doors 11 are arranged so that only one door can be opened at each operation of the apparatus, and so that the doors can only be opened when a row of compartments is in position behind the doors. Pins 53 on the doors engage bayonet slots 52 in a spring-controlled slide 51, which is moved to the right, Fig. 3, to free the doors, each time a row of compartments is in position, by means of a lever 55 operated by projections 58 on the carrier. This movement of the rod 51 allows a spring contact 59 to break a circuit 60 which does not include the switches 41, 42, this circuit preventing stoppage of the motor before a row of compartments is in position even if the handle 29 has been released. The doors work between fixed guides 12 and are provided with bevelled extensions 15 adapted to pass between the bevelled ends of slides 19, 20, 21, which can move laterally only a sufficient distance to enable one door to be opened at a time. During the opening movement, a guide 16 on the door returns the slide 18 by engaging a pin 17 and frees the lever 28; which is returned by the spring 61 into the position shown with a projection 24 in the path of the slide 19. The apparatsu is shown adapted to vend goods of two different values, being provided with two sets of coin mechanism, but with a single motor 7, battery 43, and slide 51. Coin action, mechanical-connexion and multiple-coin.-The coin mechanisms are identical and are provided with separate shoots. A coin 36 resting on a fixed support 34 in a slot in the slide 19 serves to lift the lever 28 by engaging a curved surface 37 so as to remove the projection 24 from the path of the slide 19 and permit the full movement of the operating- handle.
