In cement block building construction, it often times is necessary to place grout inside of the cement blocks after the blocks have been laid in place. Historically this has involved labor intensive activity especially if the grout is being placed at the first or second story level. One technique is to use a grout pump which takes a lot of time to set up and dismantle. An average of 200 feet of two inch hose is required to get from the pump to the location. This involves three to four men moving hoses during pumping. The other historical approach is to use a mortar tub, shovel and five gallon buckets. The five gallon buckets are filled from the mortar tub and raised by hand to a place to where the grout or mortar would be put into the cement block. This is also very labor intensive. An attempt to solve this problem is shown in U.S. Pat. No. 5,592,760 Kohout which uses a scoop to load grout into the scoop and there is an auger connected to an opening, the auger being hydraulically operated. In use, the opening is placed near the location where the grout is to be delivered. This limits the flexibility of use of the device and also there is no provision to stop the flow of the grout from the opening.
Applicant's grout hopper and dispenser utilizes a container into which grout may be placed. The bottom of the container has an auger which moves the grout into a tube. When the auger is not turning, it functions as a shut off valve in the tube and when the auger is moving, the grout moves through a flexible hose so that the grout may be placed conveniently in the preferred locations in the cement block construction. The auger is hydraulically operated and remotely controlled by the operator of a forklift which is used to lift the entire container and dispenser into position above the cement block portion of the building into which the mortar or grout is to be introduced. The auger is remotely controlled by the forklift operator responding to visual signals from the workman who is placing the grout in the cement block construction.
It is therefore an object of this invention to provide a combined grout hopper and dispenser in which the flow of the grout from the dispenser may be remotely controlled.
It is a further object of this invention to provide such a grout hopper and dispenser wherein the flow of mortar from the dispenser can be carefully positioned in the cement block with a minimum amount of labor.
This together with other objects of the invention, will become apparent from the following detailed description of the invention and the accompanying drawings.
FIG. 1. Applicant's grout hopper and dispenser positioned on a forklift.
FIG. 2. Applicant's combined grout hopper and dispenser on the forklift with the grout hopper in position so that gravity flow with the help of the auger will permit the grout to be directed to the appropriate position in the concrete block wall under construction.

It will be noted that when the auger 26 is not turning, because of its placement in the tube 13, and because of the nature of the product being delivered, it acts as an effective shut off valve to prevent more of the grout to flow through the tube.
In use the grout hopper and dispenser 10 may be slid over the forklift arms 25—25 (see
By utilizing Applicant's invention, a minimum amount of labor is required and the workmen are able to place the grout with great accuracy in the concrete block openings. The forklift can move the grout hopper and dispenser 10 slightly on command from the workman 19 to the forklift operator as needed. When the grout is fully discharged from the grout hopper and dispenser 10, it may be readily brought back down to a level where it may be refilled, thus making for a very efficient, cost effective operation.
While this invention has been shown and described with respect to a detailed embodiment thereof, it will be understood by those skilled in the art that various changes in form and detail thereof may be made without departing from the scope of the claims of the invention.
