Abstract
Abstract A lock which can be either of the padlock type or bolt type comprising, in one embodiment, a substantially U-shaped yoke or hasp having one or both of its legs provided with notches, the notched part of the legs extending into a lock body or housing. The body or housing is provided with a bore or cavity that receives an axially movable cylindrical lock casing containing lock mechanism that is effective, when key-operated, to retract a latch that normally holds the lock casing within the housing. The lock casing extends across the legs of the yoke or hasp and the notches in the legs of the yoke are shaped to conform to the cylindrical curvature of the lock casing so that the engagement between the lock casing and the legs of the yoke is effective to hold the yoke from displacement out of the lock body or housing. When the latch is retracted, the lock casing can be axially moved to withdraw it from the lock body or housing, thus freeing it from the yoke or hasp which can then be separated from the housing. A saddle or guard may be provided, attached to or separate from the lock housing, to receive the bight portion of the yoke when the yoke is in a locking position. Another embodiment of the invention involves a sliding bolt that is capable of being locked in either an advanced or retracted position by the engagement with a part provided on the cylindrical lock casing.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
154 words
A lock comprising, a lock housing having cavities, a yoke having legs adapted to enter the cavities, a cylindrical lock casing slidably fitted in the housing and extending crosswisely of the portions of the legs located in the housing, at least one of the legs being notched to fit the curvature of the lock casing, the fitment between the lock casing and the notches in the legs holding the yoke from separation from the housing, latch means operative within the housing for holding the lock casing from withdrawal out of the housing, the housing being provided with a fixed extension constituting a saddle, said saddle including a neck spaced from the legs of the yoke to result in a plurality of openings between the legs of the yoke and the neck, the saddle having a peripheral groove fitting the bight of the loop of the yoke when the yoke is coupled to the housing.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
58 words
A lock according to claim 1, wherein the fixed extension of the housing has a grooved saddle part and the neck connects said saddle part to the body of the housing, said neck defining two spaces between its sides and the legs of the yoke for the reception of elements to which the lock is to be attached.
Claim 4
Dependent Claim
113 words
A lock comprising a housing, a yoke having legs inserted in the housing, the yoke having a bight portion extending beyond the housing, a non-rotative keeper separate from the housing and fitted within the space between the bight of the yoke and the top of the housing and completeLy filling such space, said keeper being peripherally grooved to fit the bight of the yoke as well as parts of the legs thereof so that all of the portions of the yoke that extend beyond the housing are received in the groove of the keeper, and means on the keeper between the legs of the yoke for receiving a fastening element for the keeper.
Claim 5
Dependent Claim
113 words
A lock comprising a housing, a yoke having legs inserted in the housing, the yoke having a bight portion extending beyond the housing, a non-rotative keeper separate from the housing and fitted within the space between the bight of the yoke and the top of the housing and completeLy filling such space, said keeper being peripherally grooved to fit the bight of the yoke as well as parts of the legs thereof so that all of the portions of the yoke that extend beyond the housing are received in the groove of the keeper, and means on the keeper between the legs of the yoke for receiving a fastening element for the keeper.
