Claim 6

The lockset of claim 4 wherein said hand operator is a lever member and means are provided for biasing said first plate to move said actuating member to a position in which the lever is horizontal.

Claim 7

The lockset of claim 1 in which said second plate is movable between a bolt open position, a bolt partially extended position, and a bolt fully extended position, and spring means bias said second plate from its bolt open position to the bolt partially extended position to the bolt fully extended position.

Claim 8

The lockset of claim 6 wherein said drive means is rotatable in one direction from a bolt open position to a bolt partially extended position to a bolt fully extended position, and further including means for preventing said drive means from rotating from its partially extended position to its fully extended position when the locking means is unlocked but permitting said drive means to be rotated in the other direction from its partially extending position to its bolt open position.

Claim 9

The lockset of claim 7 wherein said locking means is a turn button mounted in said hand operator for movement between an unlocked position and a locked position, and said means for preventing includes means interconnecting said turn button and said drive means.

Claim 10

A lockset for a door comprising a latch bolt assembly including a bolt movable between a partially extended latching position, a fully extended dead bolt position, and a retracted position, a spindle extending through said latch assembly in a direction transverse of the direction of movement of said bolt, means connecting said spindle to said bolt for moving said bolt between its positions upon rotation of said spindle, an inside operating assembly comprising an inside hand operator having inside locking means therein, an inside first plate mounted for linear movement in a direction transverse to the axis of said spindle, an inside actuating member connected to said inside hand operator for moving said inside first plate, an inside second plate having linear movement transverse to the axis of said spindle and adapted to be moved by said first plate, and inside rotatable drive means attached to said spindle and adapted to be rotated by said second plate, and an outside operating assembly including an outside hand operator having outside locking means therein, an outside first plate mounted for linear movement in a direction transverse to the axis of said spindle, an outside actuating member connected to said inside hand operator for moving said outside first plate, an outside second plate having linear movement transverse to the axis of said spindle and adapted to be moved by said outside first plate, and outside rotatable drive means attached to said spindle and adapted to be rotated by said second plate.

Claim 11

A lockset for a door comprising a latch bolt assembly including a bolt movable between a partially extended latching position, a fully extended dead bolt position, and a retracted position, a spindle extending through said latch assembly in a direction transverse of the direction of movement of said bolt, means connecting said spindle to said bolt for moving said bolt between its positions upon rotation of said spindle, an inside operating assembly comprising an inside hand operator having inside locking means therein, an inside first plate mounted for linear movement in a direction transverse to the axis of said spindle, an inside actuating member connected to said inside hand operator for moving said inside first plate, an inside second plate having linear movement transverse to the axis of said spindle and adapted to be moved by said first plate, and inside rotatable drive means attached to said spindle and adapted to be rotated by said second plate, and an outside operating assembly including an outside hand operator having outside locking means therein, an outside first plate mounted for linear movement in a direction transverse to the axis of said spindle, an outside actuating member connected to said inside hand operator for moving said outside first plate, an outside second plate having linear movement transverse to the axis of said spindle and adapted to be moved by said outside first plate, and outside rotatable drive means attached to said spindle and adapted to be rotated by said second plate.

Claim 12

The lockset of claim 9 wherein said inside and outside second plates have gear teeth thereon and each of said inside and outside rotatable drive means includes a pinion in engagement with said gear teeth on its respective second plate.

Claim 13

The lockset of claim 9 wherein each of said inside and outside locking means rotates its respective rotatable drive means.

Claim 14

The lockset of claim 9 wherein said inside and outside first plate each includes a cam surface and each of said inside and outside actuating members is pivotably mounted and includes a cam surface for engaging said cam surface on its respective first plate to move said first plate linearly when said actuating member is pivoted.

Claim 15

The lockset of claim 12 wherein said inside and outside hand operators are a lever member and means are provided with both first plate for biasing said first plate to move said actuating member to a position in which the lever is horizontal.

Claim 16

The lockset of claim 9 in which each of said second plates is movable between a bolt open position, a bolt partially extended position, and a bolt fully extended position, and spring means bias said each of second plates from its bolt open position to the bolt partially extended position to said bolt fully extended position.

Claim 17

The lockset of claim 14 wherein said inside drive means is rotatable in one direction from a bolt open position to a bolt partially extended position to a bolt fully extended position, and further including means for preventing said inside drive means from rotating from its partially extended position to its fully extended position when either of the locking means is unlocked but permitting said inside drive means to be rotated in the other direction from its partially extending position to its bolt open position.

Claim 18

The lockset of claim 15 wherein said inside locking means is a turn button mounted in said inside hand operator for movement between a unlocked position and a locked position, and said means for preventing includes means interconnecting said turn button and said inside drive means.

Claim 19

The lockset of claim 9 further including means preventing pivoting of the outside actuating member when said second plate is in its bolt fully extended position.

Claim 20

The lockset of claim 17 in which said means preventing pivoting includes a lug extending inwardly from said outside actuating member and said outside second plate has a notch in its end portion engagable with said lug when said second plate is in its bolt fully extended position.
