Abstract
Abstract An apparatus and method of providing surveyor stakes having a top end termination indicative of a desired elevation is disclosed comprising a hydraulic cylinder supporting a cutting blade to be actuated by the cylinder; the cylinder is supported on the lower end of a levelling rod along with a stake clamp to be adjacent a surveyor''s stake during manual vertical positioning while being monitored through a transit; the stake clamp is actuated by a hand-actuated lever on the rod to hold the cutting blade fixedly with respect to a stake followed by actuation of the hydraulic cutting means by a manual hydraulic pump carried by the user when the blade is observed to be positioned at a desired elevation to cut the top of the stake and provide a resultant stake having a top end termination at the desired elevation.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
137 words
An apparatus for providing a vertically oriented stake having a top end termination at a desired elevation, said apparatus comprising a vertically movable support member, cutting means capable of severing a stake and selectively operable stake clamping means mounted on said support member for vertical movement adjacent a stake having a top end termination above said desired elevation for clampingly engaging said stake to prevent movement of said support member relative to said stake and indicator means on said support member indicative of the elevation of the cutting means so that actuation of said stake clamping means can be effected when the cutting means is at said desired elevation to maintain said cutting means at said desired elevation until said cutting means is actuated to provide a stake having a top end termination at said desired elevation.
Claim 2
Independent Claim
137 words
An apparatus for providing a vertically oriented stake having a top end termination at a desired elevation, said apparatus comprising a vertically movable support member, cutting means capable of severing a stake and selectively operable stake clamping means mounted on said support member for vertical movement adjacent a stake having a top end termination above said desired elevation for clampingly engaging said stake to prevent movement of said support member relative to said stake and indicator means on said support member indicative of the elevation of the cutting means so that actuation of said stake clamping means can be effected when the cutting means is at said desired elevation to maintain said cutting means at said desired elevation until said cutting means is actuated to provide a stake having a top end termination at said desired elevation.
Claim 3
Independent Claim
137 words
An apparatus for providing a vertically oriented stake having a top end termination at a desired elevation, said apparatus comprising a vertically movable support member, cutting means capable of severing a stake and selectively operable stake clamping means mounted on said support member for vertical movement adjacent a stake having a top end termination above said desired elevation for clampingly engaging said stake to prevent movement of said support member relative to said stake and indicator means on said support member indicative of the elevation of the cutting means so that actuation of said stake clamping means can be effected when the cutting means is at said desired elevation to maintain said cutting means at said desired elevation until said cutting means is actuated to provide a stake having a top end termination at said desired elevation.
Claim 4
Independent Claim
137 words
An apparatus for providing a vertically oriented stake having a top end termination at a desired elevation, said apparatus comprising a vertically movable support member, cutting means capable of severing a stake and selectively operable stake clamping means mounted on said support member for vertical movement adjacent a stake having a top end termination above said desired elevation for clampingly engaging said stake to prevent movement of said support member relative to said stake and indicator means on said support member indicative of the elevation of the cutting means so that actuation of said stake clamping means can be effected when the cutting means is at said desired elevation to maintain said cutting means at said desired elevation until said cutting means is actuated to provide a stake having a top end termination at said desired elevation.
