Abstract

Apparatus for mixing cementing material and mineral aggregate includes a container having a first chamber and a second chamber each having a top and a bottom. Cementing material is in the first chamber. Mineral aggregate is in the second chamber. An auger is attached to the bottom of the first and second chambers to receive and dispense cementing material from the first chamber and mineral aggregate from the second chamber. The mineral aggregate is dispensed at a rate different from that of the cementing material. The container includes extendable legs and is carried on a lift at the rear of a vehicle. The lift is raised to permit the container legs to be extended. After the legs are extended, the lift is lowered and the vehicle is driven away, leaving the container free-standing on its legs.

Claims

1. A system for transporting cementing material and mineral aggregate from a first site to a remote second site and for dispensing said cementing material and mineral aggregate at said second site, including

(a) a container having a first compartment for cementing material and a second compartment for mineral aggregate, each of said compartments having a top and a bottom;

(b) means attached to the bottom of said first and second compartments to receive and dispense cementing material from said first compartment and mineral aggregate from said second compartment;

(c) a plurality of legs connected to said container and each adjustable between a first length and a second length longer than said first length;

(d) a vehicle having a bed

(i) shaped to fit beneath said container when said legs are adjusted to said second length, and

(ii) means mounted on said bed to receive and support said container and displaceable between

a first raised operative position to support said container to permit each of said legs to be adjusted from said second length to said first length, and

a second operative position in which said bed and said container are lowered into a transport position on said vehicle.
