Abstract
Abstract A portable power tool including a housing adapted to have an electric motor supported therein. A handle is provided at one end of the housing and has a trigger disposed thereon. A tool bit extends outwardly from the other end of the housing and is rotated and impacted against by means within the housing driven by the motor. A depth rod extends from the housing parallel to the tool bit and engages the work surface when the tool bit has penetrated the work surface to the desired depth. Novel means is provided on the housing to adjustably secure the depth rod thereto.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
155 words
In a portable power tool of the type which includes a housing, a tool bit supported upon said housing and extending forwardly thereof, a motor in said housing adapted to drive said tool bit, a depth rod on said housing for indicating the depth to which said tool bit has penetrated a work surface, said depth rod including an elongated rod slidably disposed on said housing for adjustable movement in a direction generally parallel to the axis of said tool bit, means releasably retaining said rod in selected adjustable positions; the improvement wherein said retaining means includes a defectable plate secured to said housing and having opening means through which said rod slidably extends, said plate being normally disposed to grip and hold said rod against movement longitudinally thereof relative to said housing, said plate being manually deflectable whereby to release said plate from said rod, whereby said rod is manually adjustable upon said housing.
Claim 2
Dependent Claim
155 words
In a portable power tool of the type which includes a housing, a tool bit supported upon said housing and extending forwardly thereof, a motor in said housing adapted to drive said tool bit, a depth rod on said housing for indicating the depth to which said tool bit has penetrated a work surface, said depth rod including an elongated rod slidably disposed on said housing for adjustable movement in a direction generally parallel to the axis of said tool bit, means releasably retaining said rod in selected adjustable positions; the improvement wherein said retaining means includes a defectable plate secured to said housing and having opening means through which said rod slidably extends, said plate being normally disposed to grip and hold said rod against movement longitudinally thereof relative to said housing, said plate being manually deflectable whereby to release said plate from said rod, whereby said rod is manually adjustable upon said housing.
Claim 3
Dependent Claim
53 words
The improvement as defined in claim 1 wherein said rod is slidably supported in an opening means in said plate including an opening which is misaligned with said housing opening when said plate is normally disposed but which is aligned with said housing opening when said plate is deflected relative to said housing.
Claim 4
Dependent Claim
15 words
The improvement as defined in claim 2 wherein said plate is constructed of spring steel.
Claim 5
Dependent Claim
128 words
A depth rod retainer for a portable tool, said tool including a power-driven elongated bit adapted to penetrate a work surface, said depth rod including an elongated rod slidably disposed on a tool housing adjacent to and parallel to said tool bit, a plate mounted on said housing and adapted to releasably grip said rod in incrementally adjusted positions relative to said housing, said plate being movable relative to said housing substantially about an axis coplanar with said plate and perpendicular to the axis of said rod from a first position where said plate grips said rod to a second position where said rod is released for longitudinal adjustment upon said housing, said plate being resiliently biased towards said first position and manually movable to said second position.
Claim 6
Dependent Claim
128 words
A depth rod retainer for a portable tool, said tool including a power-driven elongated bit adapted to penetrate a work surface, said depth rod including an elongated rod slidably disposed on a tool housing adjacent to and parallel to said tool bit, a plate mounted on said housing and adapted to releasably grip said rod in incrementally adjusted positions relative to said housing, said plate being movable relative to said housing substantially about an axis coplanar with said plate and perpendicular to the axis of said rod from a first position where said plate grips said rod to a second position where said rod is released for longitudinal adjustment upon said housing, said plate being resiliently biased towards said first position and manually movable to said second position.
Claim 7
Dependent Claim
23 words
A retainer as defined in claim 4 wherein said plate is constructed from spring steel and is normally biased toward said first position.
Claim 8
Dependent Claim
46 words
A retainer as defined in claim 5 wherein said spring steel plate is apertured to slidably receive said depth rod, said aperture being misaligned with the axis of said rod when said plate is in said first position and aligned therewith when in said second position.
