Locking device

Claim 2

A detachable locking device for securing adjacent, cooperating closure members to prevent relative movement of the closure members comprising: a. opposed pairs of clamping members having first and second longitudinally aligned portions, said members configured to engage closure members and said first and second portions including projections with centrally located receiving means; b. interengaging, hinged connecting means joining the ends of said projections of said first portions with the ends of said projections of said second portions of each of said pairs of clamping members and cooperating with said portions to maintain them in predetermined relation when said clamping members are in closed condition; and c. removable lock engaging members joined said first portions together and said second portions together when said clamping members are in closed condition, said lock engaging members disposed within said receiving means and having ends with openings therein projecting beyond the edges of said projections to receive locking means and extending transversely of the length of said projections when said clamping members are in closed condition whereby said locking device maintains the closure members in predetermined relation when said removable lock engaging member joins said first and second portions of each of said pairs of clamping members and receives said locking means.

Claim 3

A detachable locking device for securing adjacent, cooperating closure members to prevent relative movement of the closure members comprising: a. pairs of clamping members disposed in tandem arrangement and comprising first and second portions, said first portions having aLigned facing surfaces and said second portions having aligned facing surfaces in closed condition of said pairs of clamping members, said members configured to engage closure members; b. said first and second portions of each of said pairs of clamping members disposed for mutual relative movement of said first and second portions, such relative movement creating diametrically opposed openings between facing surfaces of each of said pairs of clamping members; c. hinged members projecting from said portions of said pairs of clamping members interconnecting said first and second portions of each of said pairs of clamping members, said hinged members having centrally located receiving means on either side of the hinges; and d. removable means disposed within said receiving means interconnecting said hinged members and adapted to receive locking means for maintaining said first and second portions of each of said pairs of clamping members in closed condition when said locking means are in locked condition and to permit said first and second portions of each of said pairs of clamping members to be selectively, individually, relatively moved to an open position when said locking means are unlocked to permit relative movement of the adjacent, cooperating closure members.

Claim 4

A detachable locking device for securing adjacent, cooperating closure members to prevent relative movement of the closure members comprising: a. pairs of clamping members disposed in tandem arrangement and comprising first and second portions, said first portions having aLigned facing surfaces and said second portions having aligned facing surfaces in closed condition of said pairs of clamping members, said members configured to engage closure members; b. said first and second portions of each of said pairs of clamping members disposed for mutual relative movement of said first and second portions, such relative movement creating diametrically opposed openings between facing surfaces of each of said pairs of clamping members; c. hinged members projecting from said portions of said pairs of clamping members interconnecting said first and second portions of each of said pairs of clamping members, said hinged members having centrally located receiving means on either side of the hinges; and d. removable means disposed within said receiving means interconnecting said hinged members and adapted to receive locking means for maintaining said first and second portions of each of said pairs of clamping members in closed condition when said locking means are in locked condition and to permit said first and second portions of each of said pairs of clamping members to be selectively, individually, relatively moved to an open position when said locking means are unlocked to permit relative movement of the adjacent, cooperating closure members.

Claim 5

A detachable locking device for securing adjacent, cooperating closure members to prevent relative movement of the closure members comprising: a. pairs of clamping members disposed in tandem arrangement and comprising first and second portions, said first portions having aligned facing surfaces and said second portions having aligned facing surfaces in closed condition of said clamping members; b. said first and second portions of each of said pairs of clamping members disposed for mutual relative movement of said first and second portions, such relative movement creating diametrically opposed openings between facing surfaces of each of said pairs of clamping members; c. said first and second portions including projections, the ends of each of said projections engaging an end of a projection on a corresponding diametrically opposed portion in hinged relation; and d. removable means interconnecting said projections of each pair of said clamping members, said means adapted to receive locking means and maintain said first and second portions of each of said pair of clamping members in closed conditions when said locking means are in cooperating engagement with said interconnecting means and in locked condition and to permit selective, independent, relative hinged movement of each of said first and second portions when said locking means are unlocked to permit relative movement of the adjacent, cooperating closure members.

Claim 6

A detachable locking device for securing adjacent, cooperating closure members to prevent relative movement of the closure members comprising: a. pairs of clamping members disposed in tandem arrangement and comprising first and second portions, said first portions having aligned facing surfaces and said second portions having aligned facing surfaces in closed condition of said clamping members; b. said first and second portions of each of said pairs of clamping members disposed for mutual relative movement of said first and second portions, such relative movement creating diametrically opposed openings between facing surfaces of each of said pairs of clamping members; c. said first and second portions including projections, the ends of each of said projections engaging an end of a projection on a corresponding diametrically opposed portion in hinged relation; and d. removable means interconnecting said projections of each pair of said clamping members, said means adapted to receive locking means and maintain said first and second portions of each of said pair of clamping members in closed conditions when said locking means are in cooperating engagement with said interconnecting means and in locked condition and to permit selective, independent, relative hinged movement of each of said first and second portions when said locking means are unlocked to permit relative movement of the adjacent, cooperating closure members.

Claim 7

A locking device as recited in claim 1 wherein said means for securing closure members comprises said first and second portions of said clamping members configured to the circumferential outline of the portions of the adjacent, cooperating closure members engaged by said clamping members.

Claim 8

A locking device as recited in claim 3 wherein said projections have tongue and groove portions with a first bore therethrough and axle means received in said first bore to provide engagement of said tongue and groove portions of said projections and relative rotation of said projections; each of said projections further provided with a second bore located intermediate said tongue and groove portion and said first and second portions of said clamping members in registering relation when said first and second portions of said clamping members are in registering relation; the axis of said second bore being substantially normal to the axis of said first bore in each of said projections; said means interconnecting said projections received in said second bore of each of said projections when said second bores are in registering relation; said means interconnecting said projections including apertures, said apertures projecting beyond the ends of said secOnd bores when said projections of said first and second portions are in registering relation and adapted to receive locking means.
