The present invention is a position marking apparatus which is implemented for stamping markings on a surface, such as a wood log, at predetermined regular intervals. The position marking apparatus includes a wheel drum having an axle shaft rotatably connected to a rod on one side which extends proximally upwards to a handle for gripping, and optionally a handle extension. The position marking apparatus includes a flange mounted to the outside of the wheel drum, which is larger in diameter than the wheel drum for maintaining the wheel drum on a desired path. The wheel drum has an ink cartridge for containing ink, and at least two ink ejecting slots on the circumference of the wheel drum for marking a separation distance. The position marking apparatus includes a concave spring to ensure proper contact of the wheel drum against the surface to be marked.

Method and apparatus to assist in hanging a picture frame on a wall. The apparatus comprises a marking member which is configured to pass through an aperture of a spring-loaded outer head of an enclosure when the outer head is pressed into the enclosure. The housing has an attachment member which is removably attachable thereto having an adhesive pad for attachment onto the area where the hook of the picture frame is disposed. After the attachment member is attached to the picture frame, the enclosure is attached to the attachment member.

A telescopic marking assembly for marking on a surface or object that is out of a user's reach includes a rod that has an adjustable length. The rod is selectively extended to reach an object that is out of a user's reach. A tube is movably coupled to the rod and the tube is selectively positionable at a selected angle with respect to the rod. The tube insertably receives a writing utensil thereby facilitating the writing utensil to write on the object that is out of reach.

This invention discloses a streetlight capable of reducing air pollution of road, including a marking box (10); a marking cavity (11) disposed in the marking box (10), wherein the marking cavity (11) is provided with a laser marker (12), a rotation mechanism (90), power mechanisms (92) and a transposition mechanism (91), and the laser marker (12) is fixedly disposed on a side wall of the marking cavity (11). Feeding position of the invention is fixed, thereby realizing standardization of marking position and greatly improving quality of laser marking, and the invention aims at design of cylindrical precision devices, and automatically marks cylindrical precision devices by rotating when laser marking is carried out, and solves problem that there are fewer types of laser marking devices for this type of precision devices in market.

A marking apparatus facilitates blind slide-mounting of an object to a mounting surface in a desired alignment using the object as an alignment template. A retention element in receipt of a post is movable against resilient bias to allow the head of the apparatus to capture a mounting slot in the object. The resilient bias moves the retention element to a gripping position, and a cover is rotated to cause a tightening element to secure the grip of the apparatus to the object. A rotational detent element offset from the head prevents the post from rotating with respect to the retention element. When affixed to the object, the apparatus is used to mark the appropriate location for installation of a fastener to supportingly engage the slide-mount slot of the object. The apparatus may include an orthogonality adapter to ensure that it remains orthogonal to the object during certain marking operations.

An alignment screw. The alignment screw includes a body having a cylinder shape with a first end opposite a second end. The first end includes a male threaded portion. The second end includes a marking tip configured to mark a surface when the marking tip is pushed against the surface.

A device for marking a picture hanging spot on a mounting surface has a general U-shape encompassed by a support base, a front arm and a rear arm. The device is further provided with at least one bore, at least one pressing rod adjustably engaging within the bore, a plurality of padding means inward the U-shape, and a marking means on the rear arm facing the mounting surface. Therein, the pressing rod and the marking means are coaxially aligned, and the axis thereof is substantially perpendicular to the picture hanging spot on the mounting surface. Thereby, the pressure exerted on the pressing rod transfers through the axis thereof to the marking means that leaves a mark on the mounting surface.

Improvements in a reusable locating bracket for a recessed speaker or light bracket is disclosed. The bracket matches the hole diameter for a speaker of light. The bracket is installed prior to installation of drywall and is used as a trim guide. After installation of the drywall and cutting or trimming of the opening, the bracket is folded, bent, rotated or articulated where it can be removable through the trimmed opening in the drywall or sheet rock. The bracket has folding hinges for retaining side supports. The side supports are typically strips of cardboard, chip board or other material that provides a span from the bracket to studs, joists or beams. The folding hinges have teeth that grip the cardboard and can be opened to pull the cardboard through the retainer.

A telescopic marking assembly for marking on a surface or object that is out of a user's reach includes a rod that has an adjustable length. The rod is selectively extended to reach an object that is out of a user's reach. A tube is movably coupled to the rod and the tube is selectively positionable at a selected angle with respect to the rod. The tube insertably receives a writing utensil thereby facilitating the writing utensil to write on the object that is out of reach.

The present disclosure is directed towards the design of a marking device for writing or drawing on a given surface. The marking device can be made of any material that leaves a residue or makes legible marks on a surface brought into contact with the device. The marking device of the present disclosure can be used to make precise lines or shapes on any material, including rough surfaces, such as, wood, concrete, drywall, tiles, etc. The marking device can consistently produce thin lines without needing any sharpening. The marking device can be attached to a support frame, which can serves as a handle for grasping and using the marking device. The support frame can further provide a housing to shield the marking device from damage when not in use. In one exemplary embodiment, the marking device is shaped as a razorblade and is configured to fit into any standard utility knife. In such an embodiment, the utility knife serves as the support frame for the marking device. Such an arrangement allows a utility knife to be reversibly converted into a carpenter pencil.
