ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates generally to a valve hamper assembly. More specifically, the invention is directed to a valve hamper assembly for positioning a valve of a glassware machine.
In the past, a valve has been adjusted using shims. The shimming process is difficult and time consuming because the shims have to be placed in exact positions in order to accurately position the valve in relation to the glassware forming mold. If the valve is inaccurately positioned, the bottom of the glassware being formed by the valve is defective. Accordingly, there is a need for valve hamper assembly that eliminates the problems associated with shims.
The present invention satisfies the above-identified need. The present invention is directed to a valve hamper assembly that includes a movable valve operatively connected to a follower surface that slidingly engages a fixed camming surface to provide relatively easy, quick and accurate positioning of the valve in relation to the mold.
SUMMARY OF THE INVENTION
The present invention is directed to a valve hamper assembly having a camming surface and a movable follower surface engaging the camming surface. A movable valve is operatively connected to the follower surface. A movement device, such as a handle, is operatively connected to the follower surface for moving the follower surface along the camming surface to cause corresponding movement of the valve.
The primary object of the present invention is to provide a valve hamper assembly that easily, quickly and accurately positions a valve of a glassware machine.
Other objects and advantages of the present invention shall become apparent to those skilled in the art upon a review of the following detailed description of the preferred embodiments and the accompanying drawings.
