Referring to the accompanying drawings,

.my invention is shown in connection with a motor vehicle comprising a chassis frame A supported on wheels B, an engine C supported on the forward end of said frame and having a driving shaft connection S through housing D with the difhoused within the rear vehicle is provided with the usual cab F for the driver, the usual lever G for manipulating the transmission gearmg 'ferential driving gear from the rear driving axle. The motor vehicle construction thus far described is well known and it is considered unnecessary to il- Located back of the drivers cab F above the chassis frame A of the motor vehicle is a horizontal shaft 1, which extends longitudinally of the vehicle at the longitudinal center 'line thereof and has its ends rotatably supported in bearings 2 provided therefor on the upper ends of pedestals 3 rigidly secured to sald chassis frame. Located between the supporting pedestals 3 for the shaft 1 is a semi-cylindrical tank or container 4 adapted that is to be transported. The trough-like container 4 is and the usual clutch pedal for con-. nectIng-the engine with and disconnecting it supported on said shaft. The container is also supported intermediate its ends on a roller earlng 5 journaled in a bracket 6 fixed to a cross member 8 which extends from side rail to side rail of the chassis frame A of the vehicle. The right side wall of the container is 'provided, at a point substantially midway of its length, with a laterally projecting discharge spout or hopper 9 having converging side walls extending from the end of the container to the mouth of the discharge spout and having its bottom inclined upwardly and outwardly from the lower portion of said side wall of said container to the mouth of said discharge spout. This construction of rotary, right-hand, side delivery container permits the container to be readily discharge-d -or emptied by rotating it in a direction that will cause its discharge spout to swing downwardly into a position which will permit the contents of the container to flow therefrom by gravity; it also permits the quantity of concrete discharged from the container to be regulated by varying the angular position of the discharge spout; and it also permits the concrete to be discharged into a form while driving the vehicle along the side thereof, thereby securing an' even distribution of the concrete lengthwise of the form.

The left hand side of the container is weighted to cause the container to return to its normal or upright position after bein rotated to discharge position; and the left rear corner of the container is, provided with a suitable stop 4 adapted to abut against the left side rail of the chassis frame and thus limit the return movement of said container. The container is rotated on its axis in a direction which will cause the discharge spout on the right side thereof to swing downwardderv sides of the teeth of 1y to discharge its contents by means of a cross shaft 10, which is journaled in bearings on the chassis frame A beneath the container and is provided at one end with a removable crank 11, whereby said shaft may be manually rotated. The other end of the shaft 10 is provided with a worm 12 which meshes with a worm gear 13 fixed to a shaft 14 having a pinion 15 fixed thereto which meshes with bottom of the container. worm gear 13 are The worm 12 and preferably located within a suitable housing '17 mounted on the chassis frame A. Mounted for vertical swinging movement on the left-hand side rail of the chassis frame opposite the arcuate rack 16 on the curved bottom of the container is a pawl or ratchet 18 adapted to abut against the unsaid arcuate rack, said pawl 18 being held in engagement with said teeth by means of a coil spring 19. The

pawl 18 may be disengaged from"'thetee"h an arcuate rack 16 fixed to the curved names? of the rack 16 on the bottom of the container by means of a rock shaft 20 journaled on the left hand side rail of the chassis frame and provided at one end with a rock arm 20 adapted to bear against the inner face of said pawl. The other end of the rock arm is also provided with a rock arm 20 which is actuated to rock the rock rod bymeans ofa push rod 21 which extends crosswise of the chassis frame beneath the container. when engaged with the rack 16 acts as a brake or catch forpreventing the discharge side of the container from swinging upward, but said pawl does not interfere with the movement or said container to discharge position. The stop 4 on the container serves to limit the return movement thereof to filling position; while movement of said container to discharge position is prevented preferably by means of a chain 22, one end of which is permanently secured to the bottom of said container and the other end of which is de tachablysecured within a notch provided therefor in an upstanding bracket 23 secured to the right side rail ofthe chassis frame The concrete mixture contained within the container is continuously stirred or mixed. to preventseparation of the materials or ingre-dients thereof from the time the mixture is placed within the container to the time of its discharge therefrom, by means of a stirring device comprising two helically wound metal blades 24 mounted on the shaft 1 and rigidly secured thereto for rotation there- The pawl 18 g with preferably by means of radial arms or spokes 1 fixed to said shaft.

also serve as paddles for aiding the helical blades in stirring or mixing the concrete. As shown in the drawing the blade at one end of the tank is wound in the form of a left-hand helix and the blade at the other end is wound in the form of a right-hand helix, whereby the two blades operate to force the concrete from the ends of the container towards the middle thereof and thus operate to secure a complete dis charge of the concrete from the container.

The stirring or mixing device is rotated within the container by means of a suitable take-off box H attached to the transmission housing D and containing gears meshing with the continuous rotating gears of the transmission gearing. A continuous rotating shaft 25 projects from the take-oif box H and has a clutch connection 26 with a shaft 30 journaled in gearings provided therefor I on the inner face of the right side rail of the chassis frame and having a gear '28 fixed thereto meshing with a gear 29 fixed to the shaft 25. The clutch 26 is operated to connect the shaft 30 with the continuous rotat ing shaft 25 of the take-off box by'means of a clutch shifter lever 31 operated by means of a'hand' lever 82 fixed to a cross shaft 27, and which extends upwardly through the floor boards of the cab within easy reach of the driver. The shaft 30 which is rotatably supported on the right-hand side rail of the I vehicle has a universal jointconnection 33with on a shaft 39-located thereabove.

1 a pinion 40 which ducing gear 41'fixed to one end of the shaft the tank by forcing it 1 of the stirring mechanism. By this arrangement the stirring device may be operated from the transmission gearing when the vehicle is in motion andwhen it is standing.

The hereinbefore described stirring or mixing device secures a thorough and continuous mixing of the ingredients of the concrete in the container by maintaining the ingredients i'n a state of continual agitation from the time the concrete is placed within the container until it is discharged there from. The mixing device serves also to facilitate the discharge of the concrete from towards the discharge spout thereof. The location of the discharge spout atthe side of the container makes it easy to properly position the truck with reference to the formsor wheelbarrows; and the rate of discharge of the concrete'from the tank may be varied, depending on angular position of the discharge spout, which is vice is simple and efficient and can be readily prevented from returning to filling position by the pawl 18. The spout is swung downwardly to obtain the desired rate .of flow of the concrete by means of the cross shaft 10 and is returned to its normal position by releasing the pawl 18.

The driving mechanism for the stirring deconnected with the driving mechanism of the vehicle to drive same when the vehicle is moving .or standing by ,7 manipulating the clutch.

While I prefer to mix the concrete before placing, it in the container of the motor vehicle for transport and to use the stirring device for preventing separation of the ingredients of the concrete from the time they are placed within the container until they ,are

dischargedtherefrom, it might be desirable, in some instances, to-place the ingredients within the container before mixing and use the stirring device for initially mixing the ingredients and for maintaining such mixture during transportation.
