This invention pertains to tubular, goose neck-shaped conduits used to deliver drywall mud from a manual pump to an automatic taping machine, and more particularly to improved goose neck-shaped conduits that can be disconnected from the manual pump and selectively connected to a standard hose to deliver water to the automatic taping machine during cleanup.
Automatic taping machines simultaneously apply a strip of drywall tape coated with a thin layer of drywall mud to a joint between adjacent drywall boards. Automatic taping machines include elongated tubular bodies with interior cavities filled with drywall mud, hereinafter called ‘mud’. Located inside the interior cavity is a moveable plunger. Mounted on the upper end of the tubular bodies are head assemblies from which sections of tape and mud are simultaneously dispensed.
During use, rollers on the head assembly (not shown) are forced across the joint between drywall boards, which simultaneously pull and presses a strip of drywall table with a coat of mud over the joint. As the rollers rotate, an interior plunger (not shown) inside the interior cavity 21 moves downward and forces mud out of the interior cavity 21 and, onto the inside surface of the drywall tape.
Because the mud dries and hardens relatively quickly (typically in one to two hours), the mud filling tube 18, the inner cavity 21, and the interior plunger must be thoroughly cleaned after each use. Heretofore, drywallers must disassemble the taping machine use a garden hose to spray water over the exterior and interior parts. During cleanup, water must be sprayed at different angles to carefully all unused mud or partially dried mud particles. Unfortunately, dissembling the taping machine and manually spraying water to the individual parts often covers surrounding objects (outdoor furniture, plants, etc.) and surfaces (lawns, patios, driveways, sidewalks, etc.) with white-colored mud.
What is needed is an improved gooseneck used to deliver mud from a pump to an automatic tapping machine but also allows a drywaller to attach a hose directly to the gooseneck to deliver water to the interior cavity in the automatic tape machine during cleanup.
There is an improved gooseneck for filling drywall mud from a pump to an automatic taping machine. The gooseneck includes an upper pump plate configured to attach to the pump's output port. Formed on the upper pump plate is an inlet bore through which mud is delivered. Formed on the lower end of the gooseneck is an output port that attaches to the tape machine's mud filling tube. The pump is manually activated during use, which fills the tape machine's interior cavity with mud. The taping machine is then lifted from the gooseneck and used.
When use of the automatic taping machine has ended, the drywaller is able to clean the taping machine without disassembling the entire machine and with minimal overspray of unused or dry particles. During cleanup, the drywaller detaches the goose neck's upper pump plate from the pump. In one embodiment of the gooseneck described herein, the inlet port formed on the goose neck's upper pump plate includes internal threads compatible with external threads on a water hose. The drywaller attaches a water hose to the upper pump plate and inserts the taping machine's mud filling tube into the gooseneck's output port. Water is then delivered to the water hose to flush out unused and dried mud from the automatic taping machine.
In a second embodiment, an adapter plate is selectively attached to the upper pump plate on the gooseneck after being detached from the pump's output port. A set of threaded connectors are used to securely attach the adapter plate to the upper pump plate. The adapter plate includes an inlet port with internal threads compatible with standard external threads on a water hose.
Using one of the two described embodiments, a method for cleaning the interior cavity formed in an automatic taping machine is disclosed.
Referring to the
In a first embodiment, shown in
In a second embodiment, shown in
Each gooseneck 30, 30′ may include an optional female hose connector 40 with internal hose threads 41 and washer 42. The mud filling tube 18 fits into the connector's center bore. A male hose connector 70 may selectively attach to the connector 40 to force water into the pump 15 during cleanup.
The goosenecks 30, 30′ may also include an optional bail 80, 80′ used to attach the gooseneck to the pump 15 or to the mud taping machine 10.
Also disclosed herein is a method for cleaning the interior cavity formed in an automatic taping machine using one of the two embodiments and a garden hose that dispenses water.
In compliance with the statute, the invention described has been described in language more or less specific as to structural features. It should be understood, however, that the invention is not limited to the specific features shown, since the means and construction is shown, comprises the preferred embodiments for putting the invention into effect. The invention is therefore claimed in its forms or modifications within the legitimate and valid scope of the amended claims, appropriately interpreted under the doctrine of equivalents.
