DEFINITION

Classification: 172/96

(under subclass 91) Apparatus in which the tooth or like earth working part or portion is supported on the driven carrier by means which include a member which bends or distorts to allow said tooth or like earth working part or portion to move relative to said carrier.

(1) Note. The support may comprise a freely bendable connection or a resilient means adapted to bias the tooth or like earth working part or portion to a given position and which means may be employed either with or in lieu of a hinge connection between the carrier and said tooth, part, or portion.

(2) Note. The support may be a mere continuation of a spring formed or flexible blade or blade shank.

45, for "flail type" tools wherein a tooth or like earth working part or portion is so pivotally mounted on a driven rotary carrier that during rotation of said carrier centrifugal forces cause the free end of said tooth or like earth working part or portion to swing to a radial position relative to the axis of rotation of said carrier.

261+, for nondriven earth working elements provided with means permitting the elements to shift with respect to the earth or a supporting frame when said elements encounter an overload. 543, for rolling nondriven tools having the teeth or like earth working parts or portions thereof formed of resilient material.

544+, for rolling nondriven tools in which the teeth or like earth working parts or portion thereof are mounted on a spring or are so related to a spring that relative movement between such teeth, parts or portions and the rolling supporting structure stresses the spring.
