Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
185 words
In a hand held power drive saw unit having a reciprocating drive member and an adapter unit mountable on said drive member and having an offset portion extending laterally from the drive member and providing a U-shaped clip attachable to said offset portion by a machine screw and formed for securing the end of a saw blade to said offset portion with the saw blade substantially flat with the upper surface of the saw unit, the improvement comprising forming a groove in a side of said offset portion extending longitudinally of the drive member and adapter to receive one leg of said clip with said clip holding said saw blade against said side of said offset portion and with the teeth of said saw blade aligned with and projecting upwardly past the upper surface of the hand held power drive saw unit whereby said saw blade may be used to make "flush to" cuts, and drilling and tapping an opening in said side of said offset portion for threadably receiving said machine screw when said saw blade is in position for said "flush to" cuts.
Claim 2
Dependent Claim
185 words
In a hand held power drive saw unit having a reciprocating drive member and an adapter unit mountable on said drive member and having an offset portion extending laterally from the drive member and providing a U-shaped clip attachable to said offset portion by a machine screw and formed for securing the end of a saw blade to said offset portion with the saw blade substantially flat with the upper surface of the saw unit, the improvement comprising forming a groove in a side of said offset portion extending longitudinally of the drive member and adapter to receive one leg of said clip with said clip holding said saw blade against said side of said offset portion and with the teeth of said saw blade aligned with and projecting upwardly past the upper surface of the hand held power drive saw unit whereby said saw blade may be used to make "flush to" cuts, and drilling and tapping an opening in said side of said offset portion for threadably receiving said machine screw when said saw blade is in position for said "flush to" cuts.
Claim 3
Dependent Claim
54 words
The improvement described in claim 1 and wherein said machine screw is formed for both selectively securing said clip on top of said offset portion with said blade flat thereon for making "flush with" cuts and on the side of said offset portion with said blade against such side for making "flush to" cuts
Claim 4
Dependent Claim
127 words
An adapter as described in claim 2, and wherein the upper face of said offset portion is drilled and tapped, said U-shaped clip is formed with an opening through the web of the U, said machine screw is threadably engageable with the drilled and tapped part of said offset portion for clamping the end of a saw blade between said clip and said upper face of said offset portion with the saw blade in position for "flush with" cuts, and said side of said offset portion is drilled and tapped for threadably receiving said machine screw passing through the web of said clip for clamping the end of a saw blade between said clip and said side of said offset portion in position for "flush to" cuts.
