Abstract
Abstract A lock mechanism including a cylindrical lock casing containing cylinder lock mechanism, the casing having an axially arranged stem extending from one of its ends, said stem, extending into a hole in a transversely extending pin to thereby hold the pin against both rotative and axial movement thus coupling any element to which the pin is secured to the lock and holding such element against movement until the lock is opened and the lock casing is axially shifted.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
158 words
A lock comprising, locking mechanism contained within a cylindrical casing, said mechanism including a laterally projecting retractable latch, a substantially U-shaped housing having first and second arms, the cylindrical casing being mounted for axial movement in the first arm of the U-shaped housing, a fixed stem attached to and projecting from one end of the lock casing, a pin extending between the arms of the U-shaped housing, one end of the pin having means for anchoring that end in the second arm of the U-shaped housing, the opposite end of the pin having an enlarged disk of greater diameter than the remainder of the pin, said disk having a transverse passage therethrough, located to receive the stem on the lock casing when the casing is fitted in the housing, the latch cooperating with said first arm to hold the lock casing against axial shift in the absence of key operation of the lock mechanism in the lock casing.
Claim 2
Dependent Claim
158 words
A lock comprising, locking mechanism contained within a cylindrical casing, said mechanism including a laterally projecting retractable latch, a substantially U-shaped housing having first and second arms, the cylindrical casing being mounted for axial movement in the first arm of the U-shaped housing, a fixed stem attached to and projecting from one end of the lock casing, a pin extending between the arms of the U-shaped housing, one end of the pin having means for anchoring that end in the second arm of the U-shaped housing, the opposite end of the pin having an enlarged disk of greater diameter than the remainder of the pin, said disk having a transverse passage therethrough, located to receive the stem on the lock casing when the casing is fitted in the housing, the latch cooperating with said first arm to hold the lock casing against axial shift in the absence of key operation of the lock mechanism in the lock casing.
Claim 3
Dependent Claim
83 words
A lock according to claim 1, wherein the means for anchoring one end of the pin in the second arm of the housing comprises screw threads on the pin engageable with threaded means on the second arm, and a finger piece projecting from the disk to facilitate the rotative unthreading movement of the pin to enable it to be removed from the housing after the stem has been removed from the passage in the disk by the axial shift of the lock casing.
Claim 4
Dependent Claim
164 words
A lock comprising, a substantially U-shaped housing that includes a pair of spaced-apart arms, the first of said arms having a threaded aperture for the reception of one end of a threaded pin that extends between the arms, the second arm having an aperture, a pin having an enlarged disk at its end opposite to said threaded portion, said disk having an opening therein, the second arm of the housing having a passage at right angles to the opening therethrough and in which opening the disk is positioned, a lock casing having a key-controlled latch for holding the casing against axial shift, said casing carrying an offset stem at one end for engaging with the opening in the disk. the pin having a finger piece adjacent to the disk, the finger piece being locateD externally of the arm in which the disk is located, the pin being rotatable when it is not engaged by the stem to thereby withdraw it from the first arm.
Claim 5
Dependent Claim
164 words
