Abstract: A measuring and marking apparatus for firewood includes an upstanding tubular body having a handle, defining a channel to carry an inverted aerosol can of marking material and journaling a measuring wheel having a circumferential length equal to a desired length of firewood. The measuring wheel is journaled between wheel forks carried by and extending from the lower body portion. A protruding dog carried on a face of the measuring wheel engages an actuator carried by the body and communicating with the nozzle of the aerosol can so that each rotation of the measuring wheel causes a dispersal of marking material onto the surface being measured and marked.

Abstract: Disclosed is a device for marking the path along the ground of a rolling wheel, comprising: a container having a perimeter, and a single opening along the perimeter for dispensing a marking substance contained within the container, and a sliding gate covering the opening, the gate slidable from a closed position in which it fully covers the opening, to open positions wherein progressively more of the opening is exposed, to adjust the delivery of the marking substance through the opening. The device is mounted to the outside of the wheel so that it rotates with the wheel, the container thereby dispensing the marking substance by gravity when the container opening is rotated by the wheel rotation to a position in which the substance can fall from the container.
