Abstract: 800,256. Printing-telegraph receivers. CREED & CO., Ltd. April 27, 1956 [May 3, 1955], No. 12982/56. Class 40 (3). [Also in Group XVI] In a telegraph printer in which the message is printed on a continuous strip of message paper fed in a step-by-step manner over a platen and a stationary blade with a cutting edge projecting into the path of the strip extends transversely across it, a plurality of normally stationary gripping rollers, longitudinally spaced from the blade in the path of the strip, are periodically actuated during a stationary interval of the step-by-step feed as the leading edge of the strip reaches the rollers to tension the strip across the cutting edge to effect transverse severing of the strip. As shown in Fig. 3, the strip 19 is fed through the rear of the casing 13 over a guide 21<SP>1</SP> and over feed sprockets mounted at the ends of the shaft 24 carrying the platen. The sheet is fed line-by-line after the printing operation past a guide plate 41, the cutting edge of the blade 40 and over a guide plate 55 to the junction between a driven roller 47 and a number of rollers, not visible in Fig. 3, and mounted on a shaft 49 in bearings 50 adjustably mounted in end brackets 45 by screws 52 and springs 51. The distance between the blade 40 and engaging surface of the rollers is arranged to be slightly less than the circumference of the platen. At each revolution of the platen corresponding to approximately 21 lines, or line-spacing operations, a cam 64 on the shaft 24 operates a switch assembly 62 by which a capacitor 93 normally charged over contacts A, discharges through closed contacts B to operate a relay 90 which holds over contacts A<SP>1</SP> until the capacitor 93 has discharged. At contacts B<SP>1</SP> a motor 56 is switched in and rotates the rollers 47 so that the strip 19 is tensioned against the blade 40 and the severed portion bearing the message is fed through a shoot comprising guide wires 67, 69 to a container comprising wires 72, 75, connected to horizontal wire rods 74, 78. A number of transverse fingers 79 are secured to the wire rod 78 which is connected by links 82, 83 to the armature of a solenoid 81 which is energized when contacts are closed by a function bar 87 operated by an end-of-message signal from the transmitting station. When the fingers 79 are lowered, the sheets pass into a conveyer comprising a moving belt and inclined side walls. The cutting edge of the blade 40 is convex to the strip so that the severing operation begins at the centre of the strip and proceeds outwardly to the edges.
