Patent GB-407676-A (GB)
Abstract: 407,676. Ticket printing and issuing machines; typewriters. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and BROOME, J. H., 80, Leyland Road, Lee, both in London. Sept. 15, 1932, No. 25623. Addition to 367,354. [Class 106 (i).] The ticket printing and issuing machine described in the parent Specification is modified in that the ancillary members are not printing members but each is one of the members of an epicyclic gear the other member of the epicyclic gear being the member which is adapted to print any one of a number of selectable legends, and the clutching devices are provided for individually clutching the ancillary members to a driving means when the master member and legends which it is desired to print from the several printing members are in correct relationship. The race number printing wheel R, competitor tens printing wheel CT, and competitor units printing wheel CU are with associated spur wheels UR, UCT and UCU loosely mounted on a wheel shaft WS extending between side members fs1, fs2, of the frame F having a typebearing strip N. The frame F is keyed to the main driving shaft MD and the spur wheels UR, UCT, UCU mesh respectively, with spur wheels TR, TCT, TCU keyed to the ends of coaxial tubes TS. The tubes TS have keyed on them at their other ends spur wheels SR, SCT and SCU meshing respectively with wheels SC, &c., of clutches CUR, &c. on a lay shaft LS driven through spur wheels SL, SM from the main driving shaft MD. The shaft MD has keyed to it a spur wheel SMD connected to a motor by a clutch. The wheels UR, UCT, UCU, SC and SL are respectively one half the diameter of and have one half the number of teeth of the wheels TR, TCT, TCU, SR and SM. The ticket printing and issuing operation takes place during one revolution of the frame F. Considering for example the printing wheel R, during the first part of the cycle the wheel UR rotates on the wheel TR with the frame F, the wheel TR remaining stationary. This positions the selected type on R with respect to type N ; the electromagnet EM is then actuated to actuate the clutch CUR to connect the wheel TR with the driving means thus causing the frame F and wheels UR and TR to rotate without relative movement to effect inking from roller IR and printing from roller PP; the electromagnet EM is then deenergized, wheel TR remains stationary and wheel UR rotates on it with frame F to be returned to its normal position. Each spur wheel TR, TCT, TCU may be provided with a retaining pawl so that as it passes the inking and printing positions, friction at the relevant rollers shall not displace the wheel. As the main driving shaft MD makes a complete revolution, the spur wheel HS engaging the spur wheel SW makes a complete revolution and carries with it the paper feed segment PF, the position and length of which are such that when frame F reaches position pfs, Fig. 7, the forward end of segment PF engages spur wheel PS and thus roller FR draws forward a length of paper, and such that when frame F reaches position pff, the end of segment PF disengages spur wheel PS and thus the forward-drawing of paper ceases. Also as the main driving shaft MD makes a complete revolution the cam KC, Fig. 7, operates on member CMB whereby bottom blade BB, working against top blade BT, Figs. 7 and 8, cuts a ticket blank from the already forward fed paper. The position of the cam KC with reference to shaft SH and consequently other moving parts is such that the paper is cut at approximately the time that frame F is passing cp, Fig. 7. The wheel CT bears a symbol T for printing test tickets. A test ticket can also be issued by operating the machine by hand without any clutch being operated, in which case by the time the frame reaches the inking position all the numbered sections of all the printing wheels will have passed position N and none will bo in position as the frame passes the printing position. Thus the ticket issued will bear only such matter as type strip N carries but will bear no numbers. For registering the number of tickets issued the outer end of the wheel shaft WS is provided with a cam WSC with which a lever LE, fulcrummed at SCL, engages, and between the side members fs1, fs2 is slidably mounted a plunger PL having a roller RO at one end and bearing against lever LE at the other end. A spring SPP, acting against member fs2 and a pin PI, maintains the plunger in its forward position and consequently maintains lever LE in engagement with the face of cam WSC. At each revolution of the frame F the roller RO strikes a trigger TRI for operating a register REG, Fig. 3. No count is made of test tickets, the cam WSC being so shaped that as the section marked T of wheel CT is in the selected position, the lever LE is operated and moves roller RO out of path of trigger TRI. The operation of the clutches CUR, &c., Fig. 1, may be controlled, as in the parent Specification, by a wiper co-operating with contacts energized by keys appropriate to the several clutches. Also, as in the parent Specification, the clutch CUR appropriate to the race number wheel may be controlled by the wiper, the contacts being energized by a race number switch. The circuits by which the race number switch controls the unlocking of the machine are shown in Fig. 12. Key KR1 is closed when the machine is to be unlocked for the first race and if switch RSE is in the correct position for that race, a circuit is completed from positive, over the key, wire W1, contact O on bank RSEI, wiper WSEI, winding (I) of relay CRN to negative. Relay CRN closes contacts not shown and thus completes a circuit for unlocking the machine. Key KR2 is actuated to unlock the machine for the second race and so on with the other keys. According to the Provisional Specification paper alarms for indicating that paper has not been fed forward or that the supply is exhausted may be provided as may also a lid switch and race number indicator. The latter may consist of a uniselector which carries on its axle a light dial upon the periphery of which race numbers are borne.
