DEFINITION

Classification: 239/746

Intermittent grip or inching type:

(under subclass 744) Apparatus in which the motive means for the mobile distributor is such that it causes a step-by-step or go-stop-go type of advance usually by employing a reciprocating or oscillating pushing or pulling means along a flexible member.

(1) Note. The flexible member may be a cable wire, or the like element which acts as either (1) a rail by having both ends fixed in position to thereby establish a predetermined pathway constraining the distributor as to the route it will travel or (2) a tether by having one end attached to the distributor and the other end fixed in position thereby constraining freedom of movement of the distributors about that fixed position.
