Abstract
Abstract An adjustable height gauge device includes a block member having at least one planar end face providing a reference measurement surface and a first bore formed therein for receiving a reciprocating plunger rod. The plunger includes an axial threaded bore which receives a threaded lift screw operated by a turnscrew member carried in a side slot of the block member. The plunger rod accommodates interchangeable extension rods for extending the height range of the device.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
232 words
An adjustable gauge device comprising: a block member having at least one planar end face; a first non-threaded bore formed in said block member having a smooth interior surface; a reciprocating plunger rod having a smooth non-threaded exterior surface received in said first bore for sliding contact with said smooth interior bore of said block member; an open-sided slot formed in said block member; an turn screw member carried in said slot; a threaded interior axial bore formed in said plunger rod; a threaded lift screw member received within and threadably mating with said threaded interior bore of said plunger rod, said lift screw being keyed to said turn screw member so as to effect reciprocation of said plunger rod; guide means for limiting the reciprocation of said plunger rod to translatory motion including a longitudinal groove formed in said exterior surface of said plunger rod and a guide pin carried by said block member extending into said groove preventing rotation of said plunger rod during reciprocation; and lock means carried by said block member including a releasable cam bearing element extendable into said groove and manually operable cam lever means carried on an exterior of said block member operatively connected to said cam bearing element for selectively urging said cam element against said plunger rod within the area of said groove to lock said plunger rod in a desired height position.
Claim 2
Dependent Claim
232 words
An adjustable gauge device comprising: a block member having at least one planar end face; a first non-threaded bore formed in said block member having a smooth interior surface; a reciprocating plunger rod having a smooth non-threaded exterior surface received in said first bore for sliding contact with said smooth interior bore of said block member; an open-sided slot formed in said block member; an turn screw member carried in said slot; a threaded interior axial bore formed in said plunger rod; a threaded lift screw member received within and threadably mating with said threaded interior bore of said plunger rod, said lift screw being keyed to said turn screw member so as to effect reciprocation of said plunger rod; guide means for limiting the reciprocation of said plunger rod to translatory motion including a longitudinal groove formed in said exterior surface of said plunger rod and a guide pin carried by said block member extending into said groove preventing rotation of said plunger rod during reciprocation; and lock means carried by said block member including a releasable cam bearing element extendable into said groove and manually operable cam lever means carried on an exterior of said block member operatively connected to said cam bearing element for selectively urging said cam element against said plunger rod within the area of said groove to lock said plunger rod in a desired height position.
Claim 3
Dependent Claim
33 words
The device of claim 1 wherein said groove includes a flatened bottom surface extending longitudinally along said plunger rod affording increased surface engagement with said cam element for positively locking said plunger rod.
Claim 4
Dependent Claim
41 words
The device set forth in claim 1 wherein said plunger rod includes a threaded axial bore formed in an outer free end thereof for receiving a reduced threaded end of an extension rod for extending the height range of said gauge.
