Document Burster

This burster utilizes a reciprocable burst blade 20 for splitting a continuous length of document tickets 22 along transverse perforation lines 24 defining the tickets 22.

Tickets 22 may be of the type for marking an article for sale with price and other information by magnetic encoding on a magnetic stripe 26, and by printing on a print line 28. Blade 20 reciprocates within a guide block 30, and a fixed part 32 is disposed above block 30. Part 32 has a pad 34 of resilient material in its lower face and is formed with a cavity 36 therein. A lever 38 is swingably disposed in a corresponding cavity within block 30, and lever 38 carries a pad 40 of resilient material disposed opposite pad 34. Blade 20 has an opening 42 in it which receives a tang 44 on the end of lever 38. A spring 46 is disposed in a corresponding cavity within block 30 and acts on lever 38. A strip of connected documents 22 passes between block 30 and upper part 32 and into the nip of a pair of document drive rolls 46 and 48.

A knurled roll 50 is disposed in close proximity to a rubber covered drive roll 52 driven from any suitable power source. Roll 50 has a flat 54 which is directly opposite roll 52 when the apparatus is inactive. Roll 50 has a pin 56 extending from an end of it and eccentrically located on roll 50, and a hub member 58 is journaled on pin 56 and has blade 20 embedded and fixed within it. A spring 60 extends between a fixed pin 62 and a lug portion 64 of member 58. Roll 50 has a radially extending tooth 66 formed on it, and a latch lever 68 is adapted to engage tooth 66. Leaf spring 70 is effective between a fixed pin 72 and lever 68 and...
