Abstract
Abstract A veneer clipper in which the movable knife is driven through a double-action toggle mechanism that is powered by a pair of reciprocable pneumatic motors. The toggle mechanism include two sets of corresponding pivoted joints, with each motor drivingly connected to a different one of such sets. One of the motors is mounted in a nontraveling position on the clipper''s frame, while the other motor is mounted for travel relative to the frame, generally in the same direction as the knife.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
141 words
In a clipper for cutting sheets of veneer and like workpieces including a frame and a cutting device mounted thereon for reciprocation relative thereto, a carrier member adjacent said cutting device mounted on said frame for reciprocation relative both to said frame and to said cutting device, first toggle means interconnecting said frame and said carrier member actuatable to produce reciprocation of the latter relative to the former, first motor means operatively interposed between said frame and said first toggle means operable to actuate the latter, second toggle means interconnecting said carrier member and said cutting device actuatable to produce reciprocation of the latter relative to the former, second motor means operatively interposed between said carrier member and said second toggle means operable to actuate the latter, and means interconnecting said first and second motor means for producing simultaneous operation thereof.
Claim 2
Dependent Claim
