Abstract
Abstract A ticket printing machine having reversible means for propelling a ticket between two points. The machine has a printing head which is movable transversely to the track of the ticket in a plane parallel to the plane of the ticket. The printing head is driven in steps across the track of the ticket. The arrival of the ticket at either of the two points gives rise to an output signal. Upon the occurrence of such a signal, the ticket is driven in a direction opposite to that at which it arrived at the point and is propelled back toward the other point. The printing head is operative during the traverse of the ticket in either direction to print a line of printing. In addition, when an output signal is generated denoting the arrival of the ticket at one of the points, the printing head is advanced one step across the ticket in readiness for the next line of printing.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
167 words
A ticket printing machine comprising: (A) reversible propelling means for propelling a ticket between two points, (B) a printing head, (C) means mounting said head for movement transversely to the track of the ticket in a plane parallel to the plane of the ticket, (D) driving means for driving said printing head in steps across said track of the ticket, (E) sensing means adjacent each of said two points for sensing the presence of the ticket and providing an output signal upon such sensing, (F) control means responsive to an output signal from said sensing means to reverse the operation of said reversible propelling means and the direction of movement of the ticket, (G) said printing head being operative during a traverse of the ticket, in either direction, to print a line of printing, (H) said driving means being responsive to a said output signal from said sensing means to drive the printing head one step across the ticket in readiness for a next line of printing.
Claim 2
Dependent Claim
167 words
A ticket printing machine comprising: (A) reversible propelling means for propelling a ticket between two points, (B) a printing head, (C) means mounting said head for movement transversely to the track of the ticket in a plane parallel to the plane of the ticket, (D) driving means for driving said printing head in steps across said track of the ticket, (E) sensing means adjacent each of said two points for sensing the presence of the ticket and providing an output signal upon such sensing, (F) control means responsive to an output signal from said sensing means to reverse the operation of said reversible propelling means and the direction of movement of the ticket, (G) said printing head being operative during a traverse of the ticket, in either direction, to print a line of printing, (H) said driving means being responsive to a said output signal from said sensing means to drive the printing head one step across the ticket in readiness for a next line of printing.
Claim 3
Dependent Claim
45 words
A machine according to claim 1, wherein each said sensing means comprises two light responsive devices spaced along the length of said track and operative successively by an edge of the ticket for providing an indication of the direction of travel of the ticket. pg,23
Claim 4
Dependent Claim
75 words
A machine as claimed in claim 1 and wherein between said printing head and the track of a ticket an ink ribbon is passed, the longitudinal axis of said ribbon extending at an angle lying between the direction of the track of said ticket and the direction of transverse movement of said print head whereby step by step said print head operates on portions of said ribbon extending diagonally across the width of said ribbon.
Claim 5
Dependent Claim
82 words
A machine as claimed in claim 3 and wherein said printing head is of the wire matrix type having print needles and a plate is provided on one side of which said ribbon is arranged to pass and on the other side of which said ticket is arranged to pass, said plate having apertures whereby at each step the print needles of said wire matrix printing head may gain access, via said ribbon, to the surface of the ticket to be printed.
Claim 6
Dependent Claim
20 words
A machine as claimed in claim 4 and wherein said plate is comprised of a thin sheet of beryllium copper.
Claim 7
Dependent Claim
41 words
A machine as claimed in claim 1 and wherein said propelling means comprises a plurality of capstan drive rollers on one side of the track of a ticket each associated with a pinch roller on the other side of said track.
Claim 8
Dependent Claim
52 words
A as claimed in claim 6 and wherein the mutual spacing of each capstan drive and pinch roller combination is such that at any time when a ticket is between said two points said ticket is engaged by at least one but not more than two capstan drive and pinch roller combinations.
Claim 9
Dependent Claim
30 words
A printing machine arrangement comprising a printing machine according to claim 1 coupled to and synchronized with an overprinting machine by means of which a printed ticket may be overprinted.
Claim 10
Dependent Claim
200 words
An arrangement as claimed in claim 8 and wherein said overprinting machine comprises a print wheel having a plurality of print positions coupled via a slipping clutch arrangement to a cam, means for propelling a ticket to be overprinted passed said print wheel, and, controlled by said cam, an inking member provided to move towards and away from a print position on said print wheel and a pressure member provided to urge, when said last mentioned print position is adjacent, said ticket towards said last mentioned print positions, there being provided means for holding said cam stationary in a datum position against drive via said slipping clutch, means for driving said print wheel together with said cam whereby in operation the latter reaches its datum position and is held with said cluth slipping and said print wheel continuing until a selected datum position is reached depending upon the print position selected, and means timed to the passage of a ticket into said over printing machine for releasing said cam and causing said print wheel to be driven whereby, in sequence, said selected print position only is inked by said inking member and reaches said pressure member together with said ticket.
Claim 11
Dependent Claim
45 words
An arrangement as claimed in claim 9 and wherein said propelling means comprises a plurality of capstan drive rollers on one side of the track of a ticket through the machine 21 each associated with a pinch roller on the other side of said track.
Claim 12
Dependent Claim
22 words
An arrangement as claimed in claim 10 and wherein two capstan drive and pinch roller combinations are provided in said overprinting machine.
Claim 13
Dependent Claim
30 words
An arrangement as claimed in claim 10 and wherein stepper motors with similar characteristics are used for the capstan drive rollers in the main printing machine and the overprinting machine.
Claim 14
Dependent Claim
43 words
An arrangement as claimed in claim 10 and wherein the shafts of said capstan drive rollers are gear driven with said print wheel and the shaft of one of said capstan drive rollers carries said slipping clutch via which said cam is drivable.
Claim 15
