Secure locking arrangement

A locking arrangement comprising:

• a solid lock body, said body being defined by two opposite sides formed by parallel faces and a side wall extending between and around the perimeters of said faces, a first passageway extending through said body between, and normal to, said faces, a second passageway extending in from the body wall to transversely intersect the first passageway to pass therethrough,
• an elongated element configured to fit closely, but slidably through said first passageway to extend beyond both of said faces for engagement of its extremities with members to receive the extending extremities of said element and to be secured thereby, said elongated element having at least one orifice intermediate its extremities and co-alignable with the second passageway in the lock body when the element is disposed in the first passageway,
• an elongated lock secured in said second passageway of the lock body, said elongated lock including a plunger axially movable in said second passageway from a first position removed from the first passageway, to a second position extending through the first passageway and through said at least one orifice when said element has been disposed in said first passageway and its orifice is aligned with the second passageway;
• said elongated lock having a key receiving outer extremity and being operated by a key insertable into the last said extremity to move the plunger between its first position and its second position, in which second position the elongated element is prevented from being
• within said first passageway, and upon turning the key and removing it from the key receiving extremity, the plunger is maintained in its second position, thereby to secure the said elongated element against any movement relative to the lock body.

• and upon turning the key and removing it from the key receiving extremity, the plunger is maintained in its second position, thereby to secure the bar against any movement relative to the lock body, and the abutting members against movement relative to each other.

Means for securing two abutting members against movement relative to each other, one of said members comprising a vertical wall, and the other of said members comprising a door which swings about an axis parallel to said wall and in closed position is perpendicular to the wall, said door having a planar surface, said means comprising a first rigid plate-like element secured to the planar surface of the door adjacent an edge thereof, and a second rigid plate-like element also secured to the door and in parallel alignment with the first rigid element;

• each of said first and second elements being configured to define with the planar door surface to which each element is secured, an opening, said openings being co-aligned;
• said elements being spaced apart by a predetermined distance;
• and said wall having an aperture adjacent to said openings and in alignment therewith when the door is in closed position;
• a solid lock body, said body being defined by two opposite sides formed by parallel faces spaced apart by a distance slightly less than said predetermined distance, and a side wall extending between and around the perimeters of said faces, a first passageway extending through said body between, and normal to, said faces;
• a second passageway extending in from the body wall to transversely intersect the first passageway to pass therethrough, said lock body being disposed between said plate-like elements with its first passageway coaligned in register with said openings,
• an elongated bar configured to fit closely, but slidably, and disposed in said openings and through said first passageway in the lock body to extend into the wall aperture, said elongated bar having at least one orifice intermediate its extremities and co-alignable in register with the second passageway in the lock body when the bar is disposed in the first passageway,
• an elongated lock secured in said second passageway of the lock body, said elongated lock including a plunger axially movable in said second passageway from a first position removed from the first passageway, to a second position extending through the first passageway and into said at least one orifice when said bar has been disposed in said first passageway with an orifice aligned with the second passageway;
• said elongated lock having a key receiving outer extremity and being operated by a key insertable into the last said extremity to move the plunger between its first position and its second position, in which second position the bar is prevented from being moved within said first passageway;
• and upon turning the key and removing it from the key receiving extremity, the plunger is maintained in its second position, thereby to secure the bar against any movement relative to the lock body, and the abutting members against movement relative to each other.

Means for securing in a fixed position a control wheel of a pressure valve having a first mounting plate and an axle extending normally from said mounting plate, said axle being capped by the control wheel, said means comprising a locking arrangement as a solid lock body, said body being defined by two opposite sides formed by parallel faces and a side wall extending between and around the perimeters of said faces, a first passageway extending through said body between, and normal to, said faces, a second passageway extending in from the body wall to transversely intersect the first passageway to pass therethrough, one face of said lock body being secured to the mounting plate and an elongated element extending from within said first passageway outwardly to the valve wheel with its end adjacent said wheel being configured to hook over said wheel when the elongated element is secured in the lock body, said elongated element having a transverse orifice, and an elongated lock secured in said second passageway of the lock body, said elongated lock including a plunger axially movable in said second passageway from a first position removed from the first passageway, to a second position extending through the first passageway and through said orifice when said element has been disposed in said first passageway and its orifice is aligned with the second passageway;
