DEFINITION

Classification: 72/301

With bodily motion in fixed path:

(under subclass 295) Subject matter wherein the means to move or guide said movable instrumentality is effective to restrict the motion of said instrumentality to the same path whenever the motion occurs.

(1) Note. Excluded, for example, would be a device wherein a work clamp is guided and moved solely by such manipulable means as a chain or a block and tackle, so that its path of motion is not positively restricted to a definite line.

SEE OR SEARCH THIS CLASS, SUBCLASS:

295, for metal deformation by two relatively movable work-gripping clamps one of which is freely manipulable, and see (1) Note above.

306+, and 308+, for metal deformation by a bodily movable clamp and a coacting tool other than a clamp.
