Marking apparatus
First Claim
1. A marking apparatus adapted for use with a can containing marking material, the can having a valve for releasing the marking material and a valve actuator mounted on the valve, the apparatus comprising a base, wheels mounted on the base for permitting the base to be rolled over a surface to be marked, a handle attached to the base and extending upwardly therefrom, a can holder mounted on the handle for holding said can, the can holder having actuator stop means for engaging the valve actuator of the can and preventing movement thereof, a trigger rod movably mounted on the handle and engageable with the can for moving the can toward the actuator stop means whereby the valve of the can is opened to release the marking material, the trigger rod including a lower end portion engageable with the can, an intermediate portion which extends generally parallel with said handle, and an upper end portion which extends generally perpendicularly to said handle, and a spring resiliently biasing said lower end portion toward said actuator stop means, whereby said lower end portion of the trigger rod can be moved away from the actuator stop means against the bias of the spring by raising said upper end portion of the trigger rod to permit said can to be inserted between the actuator stop means and the lower end portion of the trigger rod.
