DEFINITION

Classification: 414/541

And carrier or mover includes means enabling additional movement having horizontal component:

(under subclass 540) Apparatus wherein the carrier or mover is provided with means to also permit movement in a direction which is at least in part horizontal to be imparted to the load or load holder.

(1) Note. The means of this subclass has been given an `enabling' context in order not to exclude a significant volume of art wherein the force to cause the movement is a manual one.

(2) Note. The raising of a receptacle in a rectilinear manner, followed by the moving of it horizontally, or with a horizontal component, and the tipping of it to dump its contents, appears occasionally in the art of this subclass.
