Claim 4

A combination locking and latching assembly according to claim 1, comprising handle means for manually actuating the latching mechanism, independently of the key actuated means, so as to move the latch member from an extended latching position to a retracted position.

Claim 5

A combination locking and latching assembly according to claim 3, wherein said slide member and said handle means are interconnected by a lost motion connection.

Claim 6

A combination locking and latching assembly for a movably mounted door having a relatively narrow stile, comprising: a. casing structure positionable in said stile, said structure having adjacently positioned openings in an edge facing of said stile; b. a locking mechanism in said casing including a locking bolt supported for selective movements to a retracted unlocked position and to an extended locked position projecting through one of said openings; c. key actuated means operable to positions for selectively moving said locking bolt to extended and retracted positions; d. a latching mechanism including: a latch member mounted for reciprocable movements between a retracted position and an extended latching position; a lever swingably pivoted at one end, and having its other end engaged with said latch member; elongated axially movable means extending along said casing having one end operably associated with said key actuated means and its other end pivotally connected with said lever; spring means normally urging said latch member towards its extended position, and swinging said lever in a direction to axially move said elongated means towards said key actuated means; and e. rotatable cam means operable by said key actuated means to a position for moving said elongated means, lever and latch member against the action of said spring for positioning the latch member in a retracted position.

Claim 7

A combination locking and latching assembly for a movably mounted door having a relatively narrow stile, comprising: a. casing structure positionable in said stile, said structure having adjacently positioned openings in an edge facing of said stile; b. a locking mechanism in said casing including a locking bolt supported for selective movements to a retracted unlocked position and to an extended locked position projecting through one of said openings; c. key actuated means operable to positions for selectively moving said locking bolt to extended and retracted positions; d. a latching mechanism including: a latch member mounted for reciprocable movements between a retracted position and an extended latching position; a lever swingably pivoted at one end, and having its other end engaged with said latch member; elongated axially movable means extending along said casing having one end operably associated with said key actuated means and its other end pivotally connected with said lever; spring means normally urging said latch member towards its extended position, and swinging said lever in a direction to axially move said elongated means towards said key actuated means; and e. rotatable cam means operable by said key actuated means to a position for moving said elongated means, lever and latch member against the action of said spring for positioning the latch member in a retracted position.

Claim 8

A combination locking and latching assembly according to claim 5, wherein said cam means are operable to other positions for selectively actuating said locking bolt to retracted and extended positions.

Claim 9

A combination locking and latching assembly according to claim 5, including a latch actuating handle connected with said lever and being operable to swing the lever in a direction to move the latch member to retracted position.

Claim 10

A combination locking and latching assembly according to claim 7, wherein the actuating handle is connected with said lever through a lost motion connection.

Claim 11

A combination locking and latching assembly according to claim 8, wherein the lever has spaced shoulder portions circumferentially of its pivot axis, and said handle includes a rotatable member having a projection movable between said shoulder portions.

Claim 12

A combination locking and latching assembly according to claim 5, wherein said elongated means at said one end has a spring urged hinge extension adapted for engagement by said cam means when utilizing the key actuated means to move the latch member to retracted position.

Claim 13

A combination locking and latching assembly according to claim 10, wherein the hinge extension is maintained out of the path of travel of said cam means when the locking bolt is in extended position, but is spring urged into the path of travel of said cam means when the locking bolt is in retracted position.

Claim 14

A combination locking and latching assembly according to claim 10, including an actuating member connected with said bolt, and being movable by said cam means to selectively position the locking bolt in retracted and extended positions, said actuator member in the extended position of said locking bolt being engaged with and moving said hinge extension out of the path of travel of said cam means.

Claim 15

A combination locking and latching assembly for a movably mounted door having a relatively narrow stile, comprising: a. a casing structure positionable in said stile, said structure havIng adjacently positioned openings in an edge facing of said stile; b. a locking mechanism in said casing including a locking bolt pivoted for swinging movements to a retracted unlocked position and to an extended locked position projecting through one of said openings; c. a latching mechanism operable independently of said locking mechanism including a latch member mounted for reciprocable movements and being normally urged to an extended latching position; and d. key actuated means selectively connectable with said locking mechanism for moving said locking bolt to extended and retracted positions, and with said latching mechanism for moving said latch member to a retracted position.

Claim 16

A combination locking and latching assembly for a movably mounted door having a relatively narrow stile, comprising: a. a casing structure positionable in said stile, said structure havIng adjacently positioned openings in an edge facing of said stile; b. a locking mechanism in said casing including a locking bolt pivoted for swinging movements to a retracted unlocked position and to an extended locked position projecting through one of said openings; c. a latching mechanism operable independently of said locking mechanism including a latch member mounted for reciprocable movements and being normally urged to an extended latching position; and d. key actuated means selectively connectable with said locking mechanism for moving said locking bolt to extended and retracted positions, and with said latching mechanism for moving said latch member to a retracted position.
