DEFINITION

Classification: 144/386

Sensing "pattern":

(under subclass 384) Subject matter including using a contoured guide engaged by a traversing follower connected to a woodworking tool such that the tool follows a path identical to the contours of the guide as the tool engages the wood for working thereof.

(1) Note. The term "pattern" (in the title) refers to a model or prototype insertable into and removable from the machine and having a shape or configuration exactly similar or proportional to the shape or configuration of the desired product. A cam or eccentric or other object which is distorted with respect to the desired product is not considered to be a pattern, and control disclosures of such objects may be found in other subclasses appropriate to the woodworker.
