Patent GB-289408-A (GB)
Abstract: 289,408. Klein, G., and Massot, P. D. L. April 26, 1927, [Convention date]. I n d e x type - wheel machines with printing- surfaces for tickets.- Comprises printing apparatus for cancelling travel vouchers constituted by a band of tickets of unit value. the number of which is a function of the length of the journey, the length and position of the slot for introducing the tickets into the apparatus being varied according to the dimensions of the voucher to be cancelled, which dimensions correspond to the length and class conditions of the journey. The extremities of the slot 1<1> are formed by walls 2, 3 that can be displaced so that when a voucher of the type described in Specification 289.407. [Class 106 (iii), Fares &c.], is used, the wall 3 can occupy one of three positions corresponding to the second class, and the wall 2 is adapted to occupy one of 5 positions. A " travel " lever 4 is keyed to the spindle 5 carrying a member 6, one extremity of which is engaged in a slotted head 7 in one with a slide carrying the wall 2. The wall 3 is moved by a lever 25 and link 24 from a lever 20 mounted on a fixed pivot 21. The lever 20 carries the pivot 19 of a differential lever 18 the movement and position of which depend on the travel lever 4 and upon a " class " lever 10 on the axle 11. Two conjoined cams 36, 36<1> carried by the member 6 operate respectively on ''rollers 35, 34 of the lever 31 having a pivot 32, which lever occupies two positions, being engaged by the cam 36 and projection 33, or by the cam 36<1> and projection 33<1>. The lever 31 carries a roller 37 working in a groove 38 in the differential lever 18. An arm 16 on the axle 11 of the " class " lever 10 is connected to the differential lever 18 by a link 17 which has two positions (1) as shown in Fig. 2 corresponding to the second class, and (2) a first class position according to the position taken by a lever 16 which rests on one of two projections 16<1>, 16<2>, as determined by a finger 14 and cam 12. The groove 38 in the differential lever is such that when the " class " lever 10 is in the second class position, the lever 18 remains in the same position, Fig. 2, whatever journey is represented by the lever 4, and the extreme right hand position of the wall 3 is determined. In the first class position of the lever 10, if the " travel " lever 4 indicates 1 to 3 sections, the lever 18 and the wall 3 occupy a second position, and where the travel lever 4 indicates 4 or 5 sections the lever 18 and wall 3 occupy a third position. A type-wheel 48 for cancelling the commencing section to the left-hand ticket is mounted on a shaft 49, while other type-wheels 51 for cancelling the terminal section are mounted on a sleeve 52. A knob 50 numbered correspondingly to the wheel 48 serves to adjust that wheel for the commencing section. Bevel wheels 53, 54 are keyed to the sleeve 52 and shaft 49, and are connected by a bevel wheel 55 loose on the axle 56 carried by a sleeve 57 free on the shaft 49, the sleeve 57 carrying a sector 62 meshing with a toothed wheel 58 positioned through gears 59, 60 from the shaft 5 of the lever 4. A wheel 78 moved through a gear from the sleeve 52 is visible through a window 80 and reproduces the indication which the devices 51 will impress on the ticket. A notched plate 63 fixed to the gear 60 co-operates with a roller on a spring lever, and a star wheel on gear 54 cooperates with a second spring lever to lock the drum 51 in adjusted position. A detent cooperating with notches in the plate 63 prevents the wheel 48 taking up a wrong position. Two elements 74 adapted to enter between an abutment piece 75 and the spurs 76 of the impression mechanism 77, which is described in Specification 289.409, [Class 106 (iii), Fares &c.], slide with the walls 2 and 3 coming opposite levers not in use prevent the mechanism acting on the parts not covered by the ticket. Modified constructions of the lever 18 and its co-operating parts with the lever 31 are described. Further modifications describe a construction suitable for cases where the tariff for extras in the first class are different from those upon which the present construction is based. The wall 3 has then to be moved into 4 positions.
