Abstract: A device that can hold at least two cans of spray paint or chalk, thus enabling marking with different colors using a single device. The device comprises a staff, a can holster, a grip, a trigger and a selector. The selector comprises a selector rod moveable in or alongside the staff. At one end of the selector rod is a selector knob and at the other is an engagement mechanism that engages the spray valve of each can, one can at a time. The engagement mechanism comprises a cam and a rocker arm with two opposing fingers, one to engage each spray can when selected. Optionally one or more flag holders may be attached to the staff for holding marker flags.

Abstract: A set of collated plastic markers. The markers have a small cross-section relative to conventional plastic markers, yet are easily insertable into the ground manually or with a marker installer and stiff enough to stand up as an indicator. Each marker comprises a shaft and a flag. The shaft comprises an insertion portion, a mast, and an engagement portion. The insertion portion is substantially wedge shaped and the engagement portion is configured to provide a push surface for manual insertion or to cooperate with a marker installer. The shafts are collated before or after flags are attached and held together in a spaced-apart arrangement with one or more connectors. Preferably a set of collated shafts is molded of plastic, the shafts attached to each other with connectors that can be pulled apart by hand or sheared off with a maker installer to separate the markers from one another during installation.

Abstract: A paint stick and marker installation system for inserting a marker having shaft with a bottom end for inserting into the ground and an engagement portion of the shaft separated from the bottom end by an insertion portion of the shaft. The apparatus includes a magazine assembly configured to receive at least one marker. The magazine space has a push position in the magazine space for receiving the at least one marker. The apparatus further comprises a push assembly mounted on the magazine assembly. The push assembly is configured to engage the engagement portion of the shaft of the marker located in the push position and push the marker from the magazine assembly when the push assembly is actuated. A plurality of the markers are bonded together such that each of the markers can be removed from the rest of the plurality when inserting a marker into the ground.

Abstract: A marker for marking a ground surface is disclosed, and includes a shaft having a bottom end and a top end. The shaft includes an insertion portion for insertion into the ground. The insertion portion is located at the bottom end of the shaft. The shaft includes a mast portion for extending above the ground surface when the insertion portion is at least partially inserted into the ground. The shaft includes an engagement portion located between the insertion portion and the mast portion with the insertion portion being located between the engagement portion and the bottom end. The engagement portion is configured to be engaged and pushed to cause insertion of the shaft into the ground.

Abstract: A marker installation system comprises a marker comprising a shaft having a bottom end and a top end, and including an insertion portion, a mast portion, and an engagement portion located between the insertion portion and the mast portion. The engagement portion is configured to resist further insertion of the shaft into the ground beyond the insertion portion. The system includes a marker installation apparatus including a magazine assembly defining a magazine space in which the marker is positioned. The magazine space has a push position in the magazine space for receiving the marker. The apparatus includes a push assembly mounted on the magazine assembly to engage the engagement portion of the marker when the marker is located in the push position. The push assembly pushes the marker from the push position of the magazine assembly when the push assembly is actuated.
