Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
124 words
A machine for trimming an edge of a board to produce a variable bevelled wavy edge including: a. means for moving a board lengthwise, b. a carriage movable transversely of the direction of movement of the board, c. a driven rotatable cutter mounted on the carriage for rocking movement towards and away from the board edge, d. manually operated means for reciprocally operating the carriage so as to obtain a wavy board edge, e. remotely controlled means connected to the cutter for rocking the cutter, and f. means for mounting the remotely controlled means on the carriage to permit the cutter to rock independently of the motion of the carriage so that the board trimmed by the cutter has a randomly bevelled wavy edge.
Claim 2
Dependent Claim
124 words
A machine for trimming an edge of a board to produce a variable bevelled wavy edge including: a. means for moving a board lengthwise, b. a carriage movable transversely of the direction of movement of the board, c. a driven rotatable cutter mounted on the carriage for rocking movement towards and away from the board edge, d. manually operated means for reciprocally operating the carriage so as to obtain a wavy board edge, e. remotely controlled means connected to the cutter for rocking the cutter, and f. means for mounting the remotely controlled means on the carriage to permit the cutter to rock independently of the motion of the carriage so that the board trimmed by the cutter has a randomly bevelled wavy edge.
Claim 3
Dependent Claim
39 words
A machine as claimed in claim 1 in which the means for moving the carriage includes a lever hinged at one end and having a handle at the other and a push rod connecting the lever and the carriage.
Claim 4
Dependent Claim
224 words
A machine for trimming an edge of a board to produce a variable bevelled wavy edge including: a. means for moving a board lengthwise, b. a carriage movable transversely of the direction of movement of the board, c. a driven rotatable cutter mounted on the carriage for rocking movement towards and away from the board edge, d. manually operated means for reciprocally operating the carriage so as to obtain a wavy board edge, and e. remotely controlled means mounted on the carriage and connected to the cutter for rocking the cutter independently of the reciprocal movement of the carriage so as to obtain a varying random bevel of the wavy edge, f. the remotely controlled means for rocking the cutter including: a sliding platform mounted on the carriage for sliding movement, a double acting hydraulic cylinder mounted on the carriage, the cylinder having a piston connected to the sliding platform, an electrically controlled hydraulic power pack having a fluid connection with the cylinder and having control switches on the handle of the lever operable for controlling fluid feed to, and bleeding fluid from the hydraulic cylinder so as to effect control of reciprocal movement of the piston and the sliding platform, and means connected to the sliding platform and the cutter for rocking the cutter when the platform is moved by the hydraulic cylinder.
Claim 5
Dependent Claim
