ABSTRACT:
A pedal latching mechanism for a machine to mix mortar and plaster, which includes a latch activated by a pedal lever, the latch mechanism including a rod biased against the vertical surface of the drum of the mixer and engages with a protuberance formed by a piece of metal welded to the vertical surface of the drum and bent in such a way as to form an inclined plane.
During the rotation movement of the drum for the unloading of the mortar, the latch which is locked by the pedal, remains in contact with the surface of the inclined plane at first and then with the vertical surface of the piece of metal. When the drum returns to the upright position, the latch resumes automatically its latching position against the protuberance since it is biased by a spring.
