Abstract: 6370. Wolff, H. March 15, 1911, [Convention date]. Coin-freed apparatus.-A negative is exposed in a chamber A, Fig. 1, developed and fixed in compartments b<1>, b<2> respectively, and then passed into a copying-chamber b<3>. The copy is developed, fixed, and dried in compartments c<1>, c<2>, c<3>, and is delivered from the machine by delivery apparatus secured on the door C<1> of the lower chamber C. In the event of accident, the coin is returned to the patron. The different parts of the machine are electromagnetically actuated in turn and for the period required by means of a current-distributor such as that described in Specification 29,810/10, [Class 38 (iii), Electric motor control systems &c.]. The lighting-device for illuminating the person is fixed round the sides of the upper chamber A. An arc lamp 7, Fig. 2, in one corner directly illuminates the head of the person who positions himself in front of the exposure opening 10 by means of a mirror 13, The person is also illuminated by diffusing-surfaces 1, 3 and additional side lamps 8. The illuminating-chambers are cased in by translucent covers 4, 5, the latter having a transparent window opposite the mirror 13. The shutter of the camera consists of a rotating disk 19, Fig. 5, having an exposure aperture 21. The shutter is normally closed and held by a catch 25. At the time for exposure, an electro-magnet 28 is energized and releases the catch 25. A solenoid 31 is then energized and the armature rod 29 rotates the disk 22 and shutter disk 19 to bring the opening 21 opposite the exposure opening. The armature rod 29 and the disks 19, 22 are returned by a spring acting to return the armature rod. The tanks in the compartments b<1>, b<2>, c<1>, c<2> are filled with measured quantities of fluids from reservoirs 37, Fig. 8, which communicate with a gauge 40 through a small orifice 38. The gauge is fitted with an open tube 47. At the required moment, an electro - magnet 46 retracts a plug 42. The liquid empties very quickly from the gauge 40 through a vessel 41 and into the tank, and the plug is thereupon closed by a spring 44. The tanks 48, Fig. 11, are narrow vertical receptacles which are fitted with plugs similar to the plug 42, Fig. 8, for discharging the liquid, and are also closed at the bottom by a plug 49 mounted on a transverse bar 54. The bar 54 is adjustably mounted on a pivoted frame 50 and the plug 49 is normally closed by a pivoted frame 59 fitted with catches 58 engaging the frame 50. After the plate or card has been treated in the bath and the liquid discharged, an electro - magnet 62 rocks the frame 59, thereby releasing the frame 50 and plug 49, and the plate slides into the next receptacle. The plug is reclosed by an electro-magnet 53. The drying-apparatus consists of a slanting table rotated by a motor 84, Fig. 13, and on to which the card is deposited from the fixing-chamber c<2>, Fig. 1. The card is held on the table by flaps 85 and pivoted fingers 86, which are held in operative position by springs 89. After the copy has dried, electro-magnets 93, 94 operate a flattened armature 92 and bring the table to rest in the position in which one or other of the fingers 86 is at the lowest point, and the electro-magnet 91 thereupon retracts the fingers 86 against which the card is resting. The card slides from the table on to a platform 95, Fig. 1, which is raised by a motor 98 to the delivery opening. The coin-opening 64, Fig. 12, is closed during the working of the machine by a shutter 67, which is operated, immediately a coin is inserted, by an electro-magnet 72 and is held by a catch 71. When a photograph is delivered, an electro-magnet 73 releases the catch 71 and shutter 67. The coin slides into a pivoted receptacle 74 and tilts a weighted lever 78 into contact with the starting-contact 80. When a photograph is delivered, a solenoid 76 tilts the receptacle, and the coins fall into a till 81. Should, however, any mishap occur during the operation of the machine, a solenoid 77 tilts the receptacle 74 in the opposite direction and the coins are returned to the patron. Electric contacts 99, Fig. 1, on the doors of the casings consist of a terminal 105 on the casing C, Fig. 17, and spring terminals 103 on the door C'.
