Abstract

Abstract A mortar applying machine including a base supported on rollers adapted to roll along the top of a brick or block wall with one of the rollers being driven to move the machine horizontally along the wall. Guide rollers extend downwardly from the base to engage the sides of the wall to maintain the machine in proper alignment. A hopper is mounted on the base and is angularly adjustable to assist in controlling the flow of mortar therefrom. A vibrator is attached to the hopper to assist in moving the mortar from the hopper. A pair of oppositely extending nozzles project from the hopper to feed the mortar to the side edges of the wall. The hopper and vibrator can be removed as a unit from the machine to apply mortar in positions where the machine cannot be used due to space restrictions. When using the hopper removed from the machine one of the nozzles is blocked so that only one stream of mortar issues from the hopper.
