Abstract Driver apparatus for precisely locating and driving nails or other similar pointed fasteners. Included is a base for locating the driver on the workpiece itself including a V slot entrance for locating the driver in driving relationship to a nail which may be already prelocated on the workpiece. The apparatus includes as its basic parts a nail driver, a holder including the base portion and a spacer which is interchangeably fixed to the lower contact end of the nail driver for presetting with precision the depth to which the nail is to be driven.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
130 words
A precision nail driver for driving a nail into the surface of a workpiece to a predetermined uniform depth comprising: a base having a lower surface slidably movable over the workpiece surface; a holder mounted on said base; a lower lateral cut out formed in said holder for providing an opening vertically extending from the base; said holder further having a central bore extending there through into registration with said cut out portion; a nail driver slidably movable downwardly and upwardly in said bore; a spacer means of predetermined length removably mounted on the lower end of said nail driver and engagable with the upper surface of said base to provide a lower limit to the stroke of said nail driver whereby each nail is partially driven into the workpiece.
Claim 2
Dependent Claim
130 words
A precision nail driver for driving a nail into the surface of a workpiece to a predetermined uniform depth comprising: a base having a lower surface slidably movable over the workpiece surface; a holder mounted on said base; a lower lateral cut out formed in said holder for providing an opening vertically extending from the base; said holder further having a central bore extending there through into registration with said cut out portion; a nail driver slidably movable downwardly and upwardly in said bore; a spacer means of predetermined length removably mounted on the lower end of said nail driver and engagable with the upper surface of said base to provide a lower limit to the stroke of said nail driver whereby each nail is partially driven into the workpiece.
Claim 3
Dependent Claim
50 words
The combination as set forth in claim 1 wherein said nail driver includes at its lower end a reduced diameter end portion and wherein said spacer comprises a sleeve having a bore for engaging said reduced diameter end portion in holding relationship to provide said lower limit of the stroke.
Claim 4
Dependent Claim
38 words
The combination as set forth in claim 1 wherein said base includes a bifurcated portion and a notched opening for receiving and locating a preset nail in predetermined centered relationship to the lower end of said nail driver.
Claim 5
Dependent Claim
25 words
The combination as set forth in claim 1 wherein said spacer means comprising a sleeve axially extending in a downward direction from said nail driver.
Claim 6
Dependent Claim
50 words
The combination as set forth in claim 1 wherein said cut out portion of said holder is of a vertical sizing substantially greater than the sizing of said spacer to accommodate selective removal and substitution of different length spacer means for varying the nail driving stroke of the nail driver.
Claim 7
Dependent Claim
42 words
The combination as set forth in claim 3 wherein said bifurcated base includes a notched opening and an inwardly formed circular opening for seating each said preset nail in a centered position with respect to the lower end of said nail driver.
