Abstract
596,575. Permutation locks. ROSENFELD, P. W. Aug. 30, 1944, No. 16448. [Class 44] In a permutation lock or padlock in which the shackle or bolt element 3 is held in locking position against the action of a spring 22 by a pivoted arm or lever 14, at least two rotatable elements 7, 10, each having a slot 11, 12, are mounted so that after rotation to bring the slots into register with one another and with the arm, the elements may be moved axially to engage the arm in the slots, and then turned to move the arm about its pivot out of engagement with the shackle or bolt. As applied to the padlock shown, the rotatable elements are cylindrical, and the element 10 is integral with the cover 2, which bears index marks. The elements are mounted on a pin 4 and pressed outwardly by a spring 13. Pins 6 and 8 enable the inner cylinder 7 to be rotated by rotation of the cover. The lever 14 is also mounted on the pin 4 and is urged by a spring 15 into a notch in a block 23 to engage a pin 24 on the end of the long arm of the shackle 3, which slides in the block 23. The shackle is of the type which is rotatable about the axis of the long arm when in the free position.
