Front discharge transit mixer
First Claim
1. A transit mixer apparatus, comprising:
- a vehicle chassis having a front end portion and a back end portion;
a first pair of wheels coupled to said front end portion for supporting said chassis;
a second pair of wheels coupled to said back end portion for supporting said chassis;
a rotatable mixing drum coupled to said chassis, said mixing drum having a front end positioned above said front end portion and a back end positioned above said back end portion, said mixing drum having an opening at said front end through which materials are loaded into or discharged from said drum, said mixing drum inclined upwardly toward the front end portion of said chassis; and
a charge hopper having an inlet portion adapted for receiving material therein and a tongue portion pivotally coupled thereto and in material communication therewith, said tongue portion extending through said opening into said mixing drum and moveable between a first position for charging said mixing drum and a second position for discharging material from said mixing drum.

Abstract
The present invention defines a transit mixer for the delivery of materials to a job site. The transit mixer has a charge hopper for receiving material therein and delivering the material to the mixing drum which forms a portion of the transit mixer. The charge hopper has an inlet that is stationary with respect to the vehicle chassis, and a tongue member that is pivotally coupled to the inlet portion. A powered cylinder is coupled between the inlet portion and the tongue portion for allowing the switching between a material charging state and a discharging state. The inlet portion and the tongue portion are in material communication with one another and upon actuation of the powered cylinder the distal end of the tongue position is moved relative to the inner surface of the mixing drum. Another aspect of the charge hopper is that in the charging mode the tongue extends beyond a pair of flights within the mixing drum.
