Abstract

Abstract A nail driving tool comprising an elongated driving member including a rear portion having a striking surface and a forward portion having a longitudinal slot extending to the forward end thereof, an axial recess contiguous to the slot and a transverse notch forwardly of the recess and contiguous to both the recess and the slot. The recess is wider than the slot and includes a nail impacting surface which is generally collinear with the bottom of the slot and the striking surface along a line coincident with or parallel to the longitudinal axis of the member. An axial recess is provided in the forward end of the member and is dimensioned to receive the head of a nail whereby the nail may be driven flush with the surface.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 152 words
A nail driving tool comprising: an elongated driving member including a rear end portion having a striking surface substantially perpendicular to the longitudinal axis of said member, a transverse notch in said member near the forward end thereof, an axial recess in said member rearwardly of said notch and contiguous thereto, said recess extending rearwardly along the longitudinal axis of said member, said recess and said notch being dimensioned to receive the head of a nail, said recess including a nail impacting surface substantially parallel to said striking surface, a longitudinal slot in the forward portion of said member contiguous to said notch and extending to said forward end of said member, said slot being narrower than said recess and dimensioned to receive the shank of a nail, a nail fulcrum within said slot forwardly of said notch, said nail fulcrum, said nail impacting surface and said striking surface being substantially collinear.
Claim 2
Dependent Claim 152 words
A nail driving tool comprising: an elongated driving member including a rear end portion having a striking surface substantially perpendicular to the longitudinal axis of said member, a transverse notch in said member near the forward end thereof, an axial recess in said member rearwardly of said notch and contiguous thereto, said recess extending rearwardly along the longitudinal axis of said member, said recess and said notch being dimensioned to receive the head of a nail, said recess including a nail impacting surface substantially parallel to said striking surface, a longitudinal slot in the forward portion of said member contiguous to said notch and extending to said forward end of said member, said slot being narrower than said recess and dimensioned to receive the shank of a nail, a nail fulcrum within said slot forwardly of said notch, said nail fulcrum, said nail impacting surface and said striking surface being substantially collinear.
Claim 3
Dependent Claim 31 words

Claim 4
Dependent Claim 34 words
The device of claim 1 wherein said member includes a center portion and wherein the cross sectional dimensions of said rear end portion are smaller than the cross sectional dimensions of said center portion.
Claim 5
Dependent Claim 21 words
The device of claim 3 wherein said center portion is hexagonal in cross section and said rear end portion is cylindrical.
Claim 6
Dependent Claim 22 words
The device of claim 4 wherein the diameter of said rear end portion is smaller than the diagonal of said center portion.
Claim 7
Dependent Claim 24 words
The device of claim 3 and including an elongated extension member positioned over said rear end portion and detachably secured to said center portion.
Claim 8
