Abstract
A drywall hopper assembly that contains a double blade that can apply drywall mud to both interior and exterior drywall corners with no blade change. A zigzag blade can contain two grooves, one for interior corners and one for exterior corners. With this blade arrangement, an operator can quickly move from one type of corner to another without using multiple tools, multiple blades or hand application methods to apply mud. The present invention can contain a pliable release port to present mud equally to an interior or an exterior corner. There can be such a port on both the top and bottom of the blade so that mud is smoothly applied as trim moves through the hopper or the hopper is moved along the trim.

FIGS. 1-2 show general perspective views of the present invention. Ahopper 1 withslanted side walls 2 narrows into ametal blade 3 at its base. Theblade 3 can contain two parallel sub-blades in the form of a zigzag, one forexterior corners 4 and one forinterior corners 5. Above the blade can be acontrol plate 8 that can be secured to the slantingside walls 2 with a protruding screw and wingnut. The unique shape of thezigzag blade 3 andcontrol plate 8 allows instant application of mud to both interior and exterior corners with no blade change and no manual application necessary. Thehopper 1 can be made of any durable material with plastic being preferred. The blade can be any hard, very rigid material with steel or aluminum being preferred. -
FIG. 3 is a top view looking into thehopper 1. Theslanted side wall 2 is visible along with a mud outlet opening 6 in the bottom of thehopper 1. The mud opening 6 dumps mud onto theblade top surface 4. -
FIGS. 4A-4B show details of thecontrol plate 8. Thehopper 1 has a slanting outside surface 7 (FIG. 2 ) that can be secured to theblade assembly 3 so that thehopper 1 dumps drywall mud into it. Theblade assembly 3 contains a double blade with a section grooved forexterior corners 5 and a section grooved forinterior corners 4 if the assembly is moved against a wall, andinterior corners 5 andexterior corners 4 if a piece of trim is moved through the assembly. Acontrol plate 8 is secured onto each end of the blade with a stub screw and can be adjusted to control the release of mud. This adjustment of theend plate 8 along the stub screw determines the exact quantity of mud dispensed.FIG. 4B in particular, shows a dispensingport 10 that can be mounted behind thecontrol plate 8 at each end of theblade 3. The dispensingport 10 is specially shaped with teeth to control the outflow of mud. It can be seen that theend port 10 has the general shape of theblade grooves teeth optional protrusions 13 to reinforce the teeth. -
FIGS. 5A and 5B show how thecontrol plate 8 meshes with theblade 3. Both thecontrol plate 8 and thedispensing port 10 can contain aslot control plate 8 and dispensingport 10. The end plate can be any rigid material with steel or aluminum being preferred. Theteeth 13, 15 that are attached to the dispensingport 10 can be clearly seen. These teeth allow mud to pass out as well as controlling the amount of mud. It can be seen the dispensingport 10 also follows the general shape of theblade 3 from previous figures. The dispensingport 10 is equipped with asimilar slot 11 that matches theslot 9 in thecontrol plate 8. Both the dispensingport 10 and thecontrol plate 8 can be made of metal such as steel or aluminum or the dispensingport 10 can be made of plastic or a fibrous material, or theteeth port 10 is flexible. It can be made from flexible plastic, rubber or other material that bends or flexes easily. Thus the dispensingport 10 can be made out of any durable, flexible material with a polymer being preferred. Various soft plastics work well. The dispensingport 10 generally is able to bend slightly to dispense mud properly; however this bending action is optional. -
FIG. 6 shows a side view of theblade 3, thecontrol port 8 and the dispensingport 10 at each end of the blade. The assembly shown inFIG. 6 fits on the bottom of thehopper body 1 with theoutside hopper wall 7 generally mating with theblade 3 and the dispensingport 10. - It should be noted that alternate removable blades are possible and are within the scope of the present invention. These optional removable blades could replace the
blade 3 shown in the figures and be configured for different types of corners or joints. - The drywall mud hopper tool of the present invention can be used in two different manners. First, the tool can be moved along the seem to dispense mud on the sheetrock. Second a piece of trim material can be moved through the tool, or the tool can be moved along the piece of trim material to dispense mud on the trim material. In these two different applications of the tool, the role of the interior and exterior zigzag sub-blades is reversed. In the first case (tool moved), part of the
double blade 5 is used for exterior corners. In the second case (trim mudded by the tool), the part of thedouble blade 5 is used for interior corners since it is the trim rather than the drywall that is being mudded. The same principle applies for the other part of theblade 4. For the first case this part of theblade 4 is used for interior corners, and in the second case this part of theblade 4 is used for exterior corners. - Several descriptions and illustrations have been used to explain the present invention. One of skill in the art would realize that many changes and variations are possible. These changes and variations are within the scope of the present invention.
