Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
150 words
An electric stippling device comprising in combination: an elongated housing; an electric motor mounted within an intermediate section of said housing, a rotatable motor shaft extending from each of the opposed ends of said housing longitudinally of said housing; an eraser member mounted adjacent one end of said housing and projecting therefrom, said eraser member being connected to the motor shaft extending from one end of said motor to be rotatable therewith; a stippling shaft member mounted within said housing adjacent the other end of said housing having a stippling point affixed thereto; means operably connecting said stippling shaft member with the motor shaft extending from the other end of said motor and adapted to convert the rotary movement of said motor shaft into reciprocatory movement of said stippling shaft member; and means for selectively activating said motor and thereby rotating said eraser member and reciprocating said stippling shaft member.
Claim 2
Dependent Claim
150 words
An electric stippling device comprising in combination: an elongated housing; an electric motor mounted within an intermediate section of said housing, a rotatable motor shaft extending from each of the opposed ends of said housing longitudinally of said housing; an eraser member mounted adjacent one end of said housing and projecting therefrom, said eraser member being connected to the motor shaft extending from one end of said motor to be rotatable therewith; a stippling shaft member mounted within said housing adjacent the other end of said housing having a stippling point affixed thereto; means operably connecting said stippling shaft member with the motor shaft extending from the other end of said motor and adapted to convert the rotary movement of said motor shaft into reciprocatory movement of said stippling shaft member; and means for selectively activating said motor and thereby rotating said eraser member and reciprocating said stippling shaft member.
Claim 3
Dependent Claim
32 words
A stippling device according to claim 1, wherein a plurality of projections are provided on said other end of said housing engageable with the surface to be stippled during the stippling operation.
Claim 4
Dependent Claim
37 words
A stippling device according to claim 1, including spring means for resiliently connecting said stippling shaft member to said means for converting the rotary movement of the motor shaft into reciprocatory movement of the stippling shaft member.
