An apparatus including a first marking device; a first roller wheel; and a structure to which the first marking device and the first roller wheel are attached. The first roller wheel is configured to roll on the top of a stack of one or more plates, while the structure moves over the top of the stack, and the first marking device marks a first side of the stack with a marking material, such as ink or paint. The apparatus may further include a housing; and wherein the housing includes an enclosure containing the marking material; and a pump configured to pump the marking material out to the first marking device. The apparatus may include a second marking device, with the second marking device attached to the structure on a first side of the structure, and the first marking device attached to the structure on a second side of the structure.

A marking apparatus and its method of use facilitate blind slide-mounting of an object to a mounting surface in a desired alignment using the object as an alignment template. The apparatus includes a post element, a retention element, a tightening element and a cover. The retention element is movable against resilient bias to allow the apparatus to capture a mounting slot in the object. The resilient bias moves the retention element to a gripping position, and the cover can be rotated so as to cause the tightening element to secure the grip of the apparatus to the object. When the object is aligned with and pushed toward the mounting surface, the cover moves against an elastic bias to allow a marking end of the apparatus to contact the mounting surface so as mark the appropriate location for installation of a fastener to supportingly engage the slide-mount slot of the object.

A positioner includes a base, a marking component, and a first mounting component. The marking component includes a marking portion and a connecting portion connected with each other. The marking portion is configured to set a mark onto a mounting surface. The connecting portion is inserted into the base. The first mounting component is detachably connected to the connecting portion. An end of the first mounting component distal from the connecting portion is configured to connect to a mounting object. Each fastening structure on a back surface of the mounting object is fixedly connected to a hanging structure via the first mounting component. A plurality of matching marks are made onto the mounting surface through a plurality of positioners.

A marking device that targets a fastened member and a fastening member (5,6), the marking device comprising; a housing that covers the fastening member (5, 6); and a marking member that is coupled to the housing via a support shaft (30) and is swingable toward the fastening member (5, 6),
characterized in that when a vector having, as a start point, a marked corner part (MC1) and having the swing center (31) as an end point at is a first vector (V1a), and a vector having the marked corner part (MC1) as a start point, and is directed in a direction orthogonal to a central axis (C) of the fastening member (5) and away from the fastening member (5, 6) is a second vector (V2a), an angle (1) formed by these two vectors (V1a, V2a) is equal to or greater than 90 degrees and less than 180 degrees.

The profile matching scribing tool includes an elongated body including walls defining an interior guide within the elongated body and having at least a first opening at one end of the elongated body, and an elongated scribing element, including a pointed tip, and positioned in the interior guide within the elongated body and configured to be slidably extended out of the first opening. A marking tool guide holder is positioned on a top of the elongated body adjacent an end thereof and configured to guide and hold a marking tool transverse to the length of the elongated body, and a marking tool storage holder is positioned on the elongated body and configured to store and hold the marking tool when not in use. Also, first and second level indicators are positioned perpendicular to each other on the top of the elongated body.

A pipe marker imprints a double mark on a copper pipe used for heatless or torchless copper pipe connection in HVAC and refrigeration systems applications, such that the distance from any point between the double mark to the end of the pipe is sufficient to be inserted into the coupler for a strong, leak-proof connection between copper pipes. The pipe marker accommodates different diameters of the pipe and imprints the double mark at the correct location on the pipe based on the diameter.

A method for applying a position marking for a working position to a substrate, for example a wall, a ceiling, a floor or the like, at a marking position assigned to it, comprising: a. unsystematically or systematically moving a portable marking system over a marking area of the substrate; b. determining at least one position of the marking system; c. marking at the determined position of the marking system, provided that the determined position coincides with the marking position or at least coincides with the marking position to a predefined or predefinable degree of accuracy. The invention also relates to a marking system.

A cutting block measuring tool for making measurements on a concrete block when positioned thereon. The measurement tool has a body with a diagonal edge with measurement indicia thereon. When a numeral of the indicia indicating a distance is aligned with a first edge of the block, that distance correlates to a distance from the second end of the block to a first side edge of the body, so a cut line may be placed on the block. An opening in the body is sized for marking a gang box cut out on the block.
