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 whisker marker system has an installation apparatus, a whisker marker, a marker strip, and a whisker fastener. The installation apparatus includes a housing and a driver shaft connected to a power driver for rotating the driver shaft. A slide body coupled to the housing moves between extended and retracted positions. The slide body has a guide channel for receiving a marker strip. The marker strip includes a series of whisker markers, each bunched together with a bunching device and attached to a threaded whisker fastener. In use, the apparatus rotates the whisker fastener until it passes through the bunching device of the whisker marker. The fastener is driven into the ground until it secures the whisker marker to the ground.

Abstract: A marker installation system is disclosed for inserting a marker of the type having shaft with a bottom end for inserting into a ground surface 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 defining a magazine space 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 it is desired to insert a marker into the ground.
