Abstract: A pavement marker comprising a base member and a signal device for sending a light signal to a driver of an oncoming vehicle further includes a longitudinally extending tire directing hood member that directs tire contact away from the upper edge, upper portion, and upper generally corner portions of the signal device front face, while allowing tire contact with the lower portion of the signal device front face. The signal device front face is at a predetermined recess depth in said pavement marker, and is at a predetermined angle with respect to the roadway surface. The marker can be either a snowplowable marker or a sun country marker. The signal device optionally can be mounted on a base member by a mechanical interlock. Optional drainage channels can be provided in the base member to allow drainage of fluid from in front of the lower portion of the signal device.

Abstract: A fastener support apparatus for facilitating the installation of individual screws into a work surface, and wherein the fastener support apparatus works in combination with a drive assembly having a clutch. The fastener support apparatus includes a drive shaft oriented in force receiving relation relative to the clutch; a depth adjustment assembly located in a predetermined orientation relative to the drive shaft; a rotatable bit for engaging the head of a screw and which is disposed in force receiving relation relative to the drive shaft; a base member fixed on the rotatable bit; a sleeve telescopingly borne by the base and reciprocally moveable relative thereto; and a screw support assembly reciprocally borne by the base member and matingly interfitted with the sleeve. The screw support assembly defines a screw receiving station which is operable to receive the head of the screw.

Abstract: A fastener support apparatus for facilitating the installation of individual screws into a work surface which includes a rotatable bit for engaging the head of the screw; a housing borne by the rotatable bit and defining a passageway, and wherein the bit is received in the passageway and the housing simultaneously rotates with the bit; a screw support assembly movably borne by the housing, the screw support assembly including a passageway defining a screw receiving station and which is operable to receive the head of the screw; a locking assembly movably borne by the screw support assembly and operable to travel from a first, partially occluding position relative to the screw receiving station to a second, substantially nonoccluding position; and an actuating assembly movably borne by the screw support assembly and which positions the locking assembly in the first or second positions.

Abstract: A fastener support apparatus for facilitating the installation of individual screws into a work surface including means for driving individual screws into the work surface; a support member borne on the driving means; a screw support assembly borne on the support member and defining a screw receiving station which is operable to receive the head of the screw; a locking assembly borne on the screw support assembly and operable for travel from a first, partially occluding position relative to the screw receiving station to a second, substantially nonoccluding position; and an actuating assembly borne on the screw support assembly and which positions the locking assembly in the first or second positions.

Abstract: A fastening apparatus for installing a ribet which includes a hollow rivet body and a mandrel, the apparatus including, a means for imparting rotational movement to a drill bit; a housing borne by the rotation means and which includes an internal operating cavity, the housing operable to support the rivet; a driving assembly borne by the housing and disposed in force receiving relation relative to the drill bit; a locking assembly borne by the housing and operable to move along a predetermined path of travel from a first unlocked position to a second locked position; and a riveting assembly positioned in the internal cavity and disposed in force receiving relation relative to the locking assembly.

Abstract: An apparatus for selectively installing individual screws of a screw belt into a work surface, the apparatus including a rotational drive assembly; a housing borne by the rotational drive assembly, the housing including a screw engagement station; a driving assembly borne by the housing and engageable with the rotational drive assembly; a screw engagement assembly slideably borne by the housing and which is matingly engaged by the drive assembly and operable to urge individual screws into the screw engagement station; a releasable brake borne by the housing and which is operable to selectively secure the screw engagement assembly against motion in a predetermined direction; a positioning assembly borne by the housing and which is operable to releasably position an individual screw in substantially coaxial alignment relative to the rotational drive means whereby, during operation, the rotational drive means imparts motion to the driving assembly which drives the screw engagement assembly in a direction away fr
