Abstract
Abstract A material stripping machine including a movable carriage on which is located a motor for providing reciprocating motion to a blade member having a cutting edge for stripping material. Mounted on the carriage behind the blade member is a diverter means for diverting stripped material to either side of the carriage so that it does not block the forward movement of the machine. The cutting edge of the blade member comprises a series of beveled teeth, and the body of the blade member has projecting upwardly therefrom at least one subsidiary cutting member having a cutting edge facing the cutting edge of the blade member for cutting through materal stripped by the blade.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
88 words
Material stripping apparatus comprising in combination; a movable carriage, a blade member mounted at the front end of said carriage, said blade member having a cutting edge for stripping material, and a diverter means mounted on said carriage behind said blade member for diverting stripped material to either side of said carriage, said diverter means comprising a body extending upwardly from the base in the rearward direction of the carriage and having a pair of angularly disposed inclined surfaces sloping downwardly to opposite sides of said carriage respectively.
Claim 2
Dependent Claim
88 words
Material stripping apparatus comprising in combination; a movable carriage, a blade member mounted at the front end of said carriage, said blade member having a cutting edge for stripping material, and a diverter means mounted on said carriage behind said blade member for diverting stripped material to either side of said carriage, said diverter means comprising a body extending upwardly from the base in the rearward direction of the carriage and having a pair of angularly disposed inclined surfaces sloping downwardly to opposite sides of said carriage respectively.
Claim 3
Dependent Claim
25 words
Apparatus defined in claim 1 wherein said surfaces meet at a common line located behind the center of said blade member in general alignment therewith.
Claim 4
Dependent Claim
23 words
Apparatus defined in claim 2 wherein said surfaces have a bottom edge and wherein said common line therebetween runs into said bottom edge.
Claim 5
Dependent Claim
14 words
Apparatus defined in claim 3 wherein each of said surfaces is a plane surface.
Claim 6
Dependent Claim
14 words
Apparatus defined in claim 3 wherein each of said surfaces is a curved surface.
Claim 7
Dependent Claim
44 words
Apparatus defined in claim 2 further including a motor means mounted on said carriage and operatively connected to said blade member for reciprocating the same, and wherein said diverter means including said surfaces thereof constitutes a hood for said carriage enclosing said motor means.
Claim 8
Dependent Claim
49 words
Apparatus defined in claim 1 further including motor means for reciprocating said blade member, said blade member being positioned with respect to said carriage so that when said carriage rests on a horizontal plane, the blade member lies in a horizontal plane to be reciprocated in said horizontal plane.
Claim 9
Dependent Claim
32 words
The machine of claim 7 wherein said blade member has at least one subsidiary cutting member projecting upwardly therefrom to cut through material stripped by the cutting edge of said blade member.
Claim 10
Dependent Claim
19 words
The machine of claim 8 wherein the cutting edge of said blade member comprises a plurality of beveled teeth.
Claim 11
Dependent Claim
28 words
The machine of claim 9 wherein said motor means is located on said carriage and said diverter also constitutes a hood for said carriage enclosing said motor means.
Claim 12
Dependent Claim
122 words
Material stripping apparatus comprising in combination; a movable carriage, a blade member mounted at the front end of said carriage, said blade member having a cutting edge for stripping material, said blade member further including at least one subsidiary cutting member projecting upwardly therefrom to cut through material stripped by the cutting edge of said blade member, and a diverter means mounted on said carriage behind said blade member for diverting stripped material to either side of said carriage, and wherein the cutting edge of said blade comprises a plurality of beveled teeth extending across and constituting said cutting edge of the blade member, and wherein each of the teeth have a generally triangular shape including opposite sides converging to pointed extremities.
Claim 13
Dependent Claim
122 words
Material stripping apparatus comprising in combination; a movable carriage, a blade member mounted at the front end of said carriage, said blade member having a cutting edge for stripping material, said blade member further including at least one subsidiary cutting member projecting upwardly therefrom to cut through material stripped by the cutting edge of said blade member, and a diverter means mounted on said carriage behind said blade member for diverting stripped material to either side of said carriage, and wherein the cutting edge of said blade comprises a plurality of beveled teeth extending across and constituting said cutting edge of the blade member, and wherein each of the teeth have a generally triangular shape including opposite sides converging to pointed extremities.
