Claim 3

An improvement in a coin operated lock unit for use with a checking cabinet having a door for closing said cabinet, wherein said lock unit includes a faceplate, means for securing said faceplate to said checking cabinet, said faceplate when secured concealing rearwardly thereof hereinafter recited elements of said lock unit, a coin guide, a patron lock, a patron lock operated rotary barrel having a locking bolt connected thereto and movable therewith between cabinet door unlocked and locked positions, means normally operable for retaining said barrel and bolt in one of said positions, a coin feeler operable by a coin positioned within said coin guide to render said retaining means inoperative the improvement comprising: a custodian controlled lock accessible forwardly of said faceplate, said custodian lock including a rotary barrel having a lip carried for movement therewith, said lip when in a first position thereof securing said faceplate to said checking cabinet, said lip carrying an operating pin for movement therewith; and a control bar mounted for vertically reciprocating movement between at least first and second positions, said bar mounting coin feeler engaging means for movement therewith, said engaging means being disposed in engagement with said coin feeler when said bar is moved into said first position thereof whereby rendering said coin feeler inoperative to permit said lock unit to function in a free status, said engaging means being disposed out of engagement with said coin feeler when said bar is moved into said second position thereof whereby to permit said lock unit to function in a coin operative status, said bar defining spaced operating edges, said custodian lock barrel when rotated being adapted to move said lip in opposite directions from said first position thereof into second and third positions thereof, at least one of said second and third positions of said lip being a faceplate releasing position, said pin being alternately engageable with said edges when said lip is moved in said opposite direction so as to move said bar into said first and second positions thereof.

Claim 4

An improvement in a coin operated lock unit for use with a checking cabinet having a door for closing said cabinet, wherein said lock unit includes a faceplate, means for securing said faceplate to said checking cabinet, said faceplate when secured concealing rearwardly thereof hereinafter recited elements of said lock unit, a coin guide, a patron lock, a patron lock operated rotary barrel having a locking bolt connected thereto and movable therewith between cabinet door unlocked and locked positions, means normally operable for retaining said barrel and bolt in one of said positions, a coin feeler operable by a coin positioned within said coin guide to render said retaining means inoperative the improvement comprising: a custodian controlled lock accessible forwardly of said faceplate, said custodian lock including a rotary barrel having a lip carried for movement therewith, said lip when in a first position thereof securing said faceplate to said checking cabinet, said lip carrying an operating pin for movement therewith; and a control bar mounted for vertically reciprocating movement between at least first and second positions, said bar mounting coin feeler engaging means for movement therewith, said engaging means being disposed in engagement with said coin feeler when said bar is moved into said first position thereof whereby rendering said coin feeler inoperative to permit said lock unit to function in a free status, said engaging means being disposed out of engagement with said coin feeler when said bar is moved into said second position thereof whereby to permit said lock unit to function in a coin operative status, said bar defining spaced operating edges, said custodian lock barrel when rotated being adapted to move said lip in opposite directions from said first position thereof into second and third positions thereof, at least one of said second and third positions of said lip being a faceplate releasing position, said pin being alternately engageable with said edges when said lip is moved in said opposite direction so as to move said bar into said first and second positions thereof.

Claim 5

An improvement in a coin-operated lock unit according to claim 2, wherein said patron lock includes a patron key operated lock cylinder having ends thereof extending inwardly and outwardly of said unit through said faceplate, said lock cylinder being removably interconnected to said patron lock barrel, and said bar includes an integrally formed flange retaining means adapted to releasably engage said inwardly extending end of said lock cylinder, said flange retaining means being disengaged from said inwardly extending end of said lock cylinder to permit removal thereof outwardly of said unit when said lip is in the other of said second or third positions thereof, and said flange retaining means being engaged with said inwardly extending end of said lock cylinder so as to prevent removal thereof as aforesaid when said lip is in all other positions thereof.

Claim 6

An improvement in a coin-controlled lock unit for use with a checking cabinet having a door for closing said cabinet, wherein said lock unit includes a coin guide, a counter unit, a patron lock operated rotary barrel having a locking bolt connected thereto and movable therewith between cabinet door locking and unlocking positions, means normally retaining said barrel and bolt in one of said positions, means operably connecting said counter to said barrel such that said counter is actuated by each rotational movement of said barrel serving to move said bolt between said positions, means for retaIning in a predetermined position within said coin guide a coin deposited thereinto, coin feeler means operable by a coin retained in said predetermined position to render said first said retaining means inoperative, the improvement comprising: cam means mounted for rotational movement with said barrel and cam follower means associated with said coin-retaining means, said follower means cooperating with said cam means for releasing said coin from said predetermined position when said barrel is rotated to remove said bolt from one position to the other.

Claim 7

An improvement in a coin-controlled lock unit for use with a checking cabinet having a door for closing said cabinet, wherein said lock unit includes a coin guide, a counter unit, a patron lock operated rotary barrel having a locking bolt connected thereto and movable therewith between cabinet door locking and unlocking positions, means normally retaining said barrel and bolt in one of said positions, means operably connecting said counter to said barrel such that said counter is actuated by each rotational movement of said barrel serving to move said bolt between said positions, means for retaIning in a predetermined position within said coin guide a coin deposited thereinto, coin feeler means operable by a coin retained in said predetermined position to render said first said retaining means inoperative, the improvement comprising: cam means mounted for rotational movement with said barrel and cam follower means associated with said coin-retaining means, said follower means cooperating with said cam means for releasing said coin from said predetermined position when said barrel is rotated to remove said bolt from one position to the other.
