Abstract

621,186. Opening envelopes. HARGREAVES, R. F. Jan. 8, 1947, No. 605. [Class 31 (i)] In a device for opening letters, the edge of the envelope is cut off by the combined action of a turnable knife and a relatively fixed knife, the turnable knife being inclined to its axis of rotation so that the point of intersection of the two knives progresses from one end to the other as turning proceeds. The envelope is introduced in the opening 26a in the casing 26 and is pressed by the guide plate 24, which is pivoted at 23, against the fixed knife 19. Cylinder 13, which carries the inclined knife blade 14, is then rotated through about 90 degrees by depressing handle 17, whereby the point of contact between the two blades progresses along the knives and the edge of the envelope is cut off; springs 15 return the handle 17 and the rotary blade to their initial positions. Waste is discharged through opening 10c in the base. The fixed blade is urged downwards resiliently by springs 22 and the lowermost position of the blade is determined by adjustable screws 21.
