Abstract
Abstract A locking assembly for instantly immobilizing the motion of a slide fixture at fixed selected positions to facilitate repetitive drilling, drilling through relatively thin material with a large drill in which procedure it is imperative to lock the fixture securely and instantly and in any other precedure or technique where it is desirable to lock a slide fixture capable of two-way motion instantly and securely in position so that the work carried by the fixture will be immobilized quickly and securely by actuating a single locking handle or actuator.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
114 words
An instant locking device for immobilizing a work piece securely in fixed selected position comprising support means engaging the work piece, means supporting the support means from a support to enable the work piece to be moved freely in two perpendicular linear directions, and locking means having a single actuator for simultaneously and securely locking the support means immobilized, said means supporting the support means including a first slide rod connected to the support means, a second slide rod connected to a support and disposed in perpendicular relation to the first slide rod, and a slide block slidably engaged with both of said slide rods, said locking means being incorporated into said slide block.
Claim 2
Dependent Claim
114 words
An instant locking device for immobilizing a work piece securely in fixed selected position comprising support means engaging the work piece, means supporting the support means from a support to enable the work piece to be moved freely in two perpendicular linear directions, and locking means having a single actuator for simultaneously and securely locking the support means immobilized, said means supporting the support means including a first slide rod connected to the support means, a second slide rod connected to a support and disposed in perpendicular relation to the first slide rod, and a slide block slidably engaged with both of said slide rods, said locking means being incorporated into said slide block.
Claim 3
Dependent Claim
36 words
The structure defined in claim 1 wherein said locking means includes a movable locking member movable into a position to immobilize the slide block with respect to the slide rods, and means actuating the locking member.
Claim 4
Dependent Claim
82 words
The structure as defined in claim 2 wherein said means actuating the locking member including a screw threaded member having handle means projecting outwardly of the slide block for manipulation, and cam means interconnecting the screw threaded member and locking member for longitudinally reciprocating the locking member into locking position when the screw threaded member is rotated a partial revolution in one direction and releasing the locking member when the screw threaded member is rotated a partial revolution in the opposite direction.
Claim 5
Dependent Claim
102 words
The structure as defined in claim 3 wherein said cam means includes a conical recess in the locking member and a correspondingly shaped conical tip on the screw threaded member with the conical tip on the screw threaded member being smaller than the conical recess in the locking member but correspondingly shaped, the longitudinal axis of the screw threaded member and conical tip thereon being offset in relation to the center of the conical recess in the direction of longitudinal movement of the locking member for moving the locking member into locking position in response to roTation of the screw threaded member.
Claim 6
Dependent Claim
42 words
The structure as defined in claim 3 wherein said locking member includes a notch in one side thereof receiving said second slide rod to laterally deflect that rod into locking engagement with said first slide rod at the point of tangential adjacency.
Claim 7
Dependent Claim
52 words
The structure as defined in claim 3 wherein said locking member includes a pair of angularly disposed wedge surfaces on the inner end of the locking member for frictional locking engagement with both of said slide rods by entering into the space between the slide rods at the point of crossing thereof.
Claim 8
Dependent Claim
42 words
The structure as defined in claim 2 wherein said locking member includes a notch in one side thereof receiving said second slide rod to laterally deflect that rod into locking engagement with said first slide rod at the point of tangential adjacency.
Claim 9
Dependent Claim
72 words
The structure as defined in claim 7 wherein said means actuating the locking member including a screw-threaded member having handle means projecting outwardly of the slide block for manipulation, and cam means interconnecting the screw-threaded member and locking member for longitudinally reciprocating the locking member into locking position when the screw-threaded member is rotated in one direction and releasing the locking member when the screw-threaded member is rotated in the opposite direction.
Claim 10
Dependent Claim
36 words
The structure as defined in claim 2 wherein said locking member includes a pair of angularly disposed wedge surfaces on the inner end of the locking member for locking engagement with both of said slide rods.
Claim 11
Dependent Claim
101 words
The structure as defined in claim 9 wherein said means actuating the locking member includes a screw-threaded member having handle means projecting outwardly of the slide block for manipulation, and cam means interconnecting the screw-threaded member and locking member for longitudinally reciprocating the locking member into locking position when the screw-threaded member is rotated in one direction and releasing the locking member when the screw-threaded member is rotated in the opposite direction for engaging the wedge surfaces with both of said slide rods at the point of tangential adjacency with wedge surfaces being oppositely facing to move between the adjacent rods.
Claim 12
Dependent Claim
44 words
The structure as defined in claim 2 wherein said means actuating the locking member includes a single handle member, and movable means interconnecting said handle member and the locking member to reciprocate the locking member in response to single movement of the handle member.
Claim 13
Dependent Claim
44 words
The structure as defined in claim 11 wherein said movable means and locking member include corresponding conical recess and projection means disposed in offset relation to move the locking member when brought into engagement and the recess and projection means are moved toward alignment.
Claim 14
Dependent Claim
65 words
A locking device for locking an assembly of a slide block movably associated with a pair of perpendicular slide rods for movement in perpendicular linear directions comprising single lock means carried by said slide block for simultaneously immobilizing said block and slide rods in relation to each other, said lock means including a single actuator means for actuating the lock means with a single actuation.
Claim 15
Dependent Claim
65 words
A locking device for locking an assembly of a slide block movably associated with a pair of perpendicular slide rods for movement in perpendicular linear directions comprising single lock means carried by said slide block for simultaneously immobilizing said block and slide rods in relation to each other, said lock means including a single actuator means for actuating the lock means with a single actuation.
