Abstract: An apparatus is provided which facilitates the controlled rotative positioning of a suspended planter. The apparatus is comprised of a cylindrical outer member and an internal member in sliding engagement with said outer member and coaxially positioned therewith. The internal member is provided with two spaced arrays of teeth so arranged that, when one member is upwardly displaced with respect to the other member, bearing means associated with said outer member induce rotative motion of one of said members. Restoring means acting between said members causes said upward displacement when downward force is removed therefrom. Attachment means associated with each member facilitates suspension of the apparatus from an overhead support and suspension of a planter from that member which undergoes rotative motion.

Abstract: An apparatus is provided for use in conjunction with an electric drill to achieve precision drilling of holes at various desired angles in a workpiece. The apparatus comprises a base member which supports two pivoted, spring-containing columns bridged by a sliding carriage member carrying a spindle and chuck. The base member fits into an underlying anchoring means which assures accurate placement of the drill and steadiness of support. Hole indicator means, used in conjunction with said anchoring means enable precise location of hole sites on the workpiece.

Abstract: An apparatus is provided which facilitates the controlled rotative positioning of a planter suspended from an overhead support. The apparatus is comprised of two facing toothed members, a vertically disposed pull rod and associated bearing pin, position restoring means acting upon said pull rod, and harness means to maintain the several components in proper spaced alignment. The apparatus is attached to an overhead support, and a planter is attached by tether means to said pull rod. The apparatus causes the planter to undergo controlled horizontal rotative movement when the planter is momentarily pushed upward to remove the downward force acting upon said pull rod, and then released.
