Abstract: 586,944. Ticket - - issuing machines. LONDON PASSENGER TRANSPORT BOARD, and GIBSON, G. Dec. 27, 1944, No. 25938. [Class 106 (iii)] In a ticket printing and issuing machine in which counters are provided to totalize the various fare charges for the different types of tickets issued, said counters are actuated, when a ticket is being printed, by a wheel with two sets of teeth and a pawl and ratchet arrangement. The machine comprises a casing 80 fitted in walls 1 and 2 in which is mounted a shaft 100, Fig. 3. Inside the casing 80 are two circular plates 5 and 6, between which is mounted the printing mechanism as described later. The plate 5 is fixed to a sleeve 3 at one end of the shaft 100 and the plate 6 is rotatably mounted on a shaft 4 at the other end of the shaft 100. Within the sleeve 3 is a second sleeve 7 having at its outer end a milled head 8 and at its inner end a toothed wheel 15 which drives through a Geneva cross mechanism a printing device 17. The sleeve 7 is provided around its periphery -with numerals corresponding to fare stages and the said numerals can be viewed through an opening 18 in the sleeve 3 when setting the printing device 17. Within the sleeve 7 is a shaft 9, as shown, having at its outer end a knob 10 and at its inner end a toothed wheel 12 which drives through a Geneva cross mechanism a printing wheel 14 which prints the class of ticket being issued. The position of the knob 10 determines, therefore, what class of ticket will be issued, Fig. 1. The shaft 4 carries, at its outer end, a knurled disc 106, at its middle a drum 22, Fig. 4, on which the " fares 23 are indicated and at its inner end a toothed wheel 25 which drives through a Geneva cross device a " fare charge " printing wheel 27. The fare drum 22 which can be viewed, for setting purposes, through a window 66 in a casing 65, carries totalizers 37 for the different fare charges and the totalizer corresponding to the charge of ticket being issued as determined by position of drum 22 is actuated during the ticket printing operation. The drum 22 has a boss 35 carrying a partly-toothed wheel 30, Fig. 12, secured to which is a circular plate 38 which carries a pin 39<11> which cooperates with a toothed wheel 40, 41 to drive a totalizer 42 which counts the number of tickets issued. By depressing a push-button 51, provided outside the casing, a pin 47 on a pawl 45 mounted on plate 38, Fig. 6, is disengaged from a notch 49 in plate 2 engages the edge of circular opening 39, Fig. 7, therein while the pawl engages a wheel 44 secured to the boss 35 so locking the boss 35, shaft 4, wheel 30, disc 38, plates 5 and 6 and sleeve 3 together so that when sleeve 3 is rotated clockwise by means of a handle 21 secured thereto these parts will rotate as one and a ticket will be printed. The wheel 30 has two sets of teeth 33, 34, Fig. 12, and co-operates with a toothed wheel 59 which is rotatably mounted on the plate 2 and which carries a pawl 60 to actuate the totalizer 37 previously set by rotating knob 106. Between the plates 5 and 6 is also mounted a printing mechanism 104 which is driven by a Geneva cross device and pin and which prints the serial number of the ticket. The material for the tickets, roll 69, Fig. 10, is placed in a compartment at the top of the casing 80, the cover 68 serving as a guide for the strip. The roll 69 is placed between two plates 150 and the cover 68 carries a spring- actuated roller which presses the strip 69 against the printing wheels.
