The follower surface 82 slidably links the cam surface 80. In a preferred embodiment, the cam surface 80 has a predetermined generally cylindrical slope S. Accordingly, as the movable disk 70 is rotated, the follower surface 82 engages and displaces along the cam surface 80 to cause the movable disk 70 to rise in the direction indicated by the arrow 84 in Figure 7. The rotation of the movable disk 70 in the opposite direction causes the movable disk 70 to fall in the direction indicated by the arrow 86 in Figure 7. Referring to Figure 5, the assembly 10 includes a movable valve 90 for glassware having a first end 92 and a second end 94. The valve 90 is held in the housing 30 by a generally cylindrical valve sleeve 96 which is adapted and sized to be positioned adjacent the interior surface 36 of the housing 30. The first end 92 of the valve 90 includes a shoulder 98 which is positioned adjacent to the upper surface 72 of the movable disk 70. Accordingly, movement of the movable disk 70 in the indicated directions by the arrows 84 and 86 in Figure 7 causes the corresponding movement of the valve 90.

Referring to Figures 4-6 and 8, the first end 92 of the valve 90 includes a valve stem 100. The valve stem 100 is received by a first opening 102 defined by the movable disk 70, a second opening 104 defined by the fixed disk 60 and a third opening 106 defined by the base plate 42. The valve rod 100 acts as a rotation axis for the movable disk 70. As shown in Figure 5, the valve rod 100 defines a longitudinally extending tang recess 108 which is adapted and sized to receive the first end 52 of the retaining pin 50. When the retaining pin 50 is inserted into the tang recess 108, as shown in Figure 5, the valve stem 100 is maintained in the assembly 10. When the retaining pin 50 is removed from the recess 108, the valve stem 100, and thereby the valve 90, can be removed of the assembly 10. Referring to Figures 5 and 6, the second end 94 of the valve 90 is adapted and sized to form a predetermined shape in a glass article (not shown) that is being formed in the mold 20. As best shown in Figure 6, the second end 94 of the valve 90 forms the lower part of the glass article. Referring to Figures 4, 5 and 8, the assembly 10 includes a handle 110 having a stem 112. The stem 112 includes a knob end 114 and a tie end 116. The knob end 114 includes a dial knob. 118. The connecting end 116 is fixedly attached to the movable disk 70. The connecting end 116 is fixedly attached to the movable disk 70. As shown in Figure 8, the housing 30 defines a slit 120. The handle 110 can move within of the slit 120 in a first direction indicated by the arrow 122 and a second opposite direction indicated by the arrow 124. Due to the connection of the handle 110 to the movable disk 70, the movement of the handle 110 in the directions indicated by the arrows 122 and 124 causes corresponding rotational movement of the movable disk 70. Referring to Figures 4 and 8, the assembly 10 includes an index gate 130 pivotally mounted on the outer surface 36 of the housing. 30 by means of bolts 132. The index gate 130 includes first, second, third, fourth, fifth, sixth and seventh mization slots 134, 136, 138, 140, 142, 144 and 146, respectively. The stem 112 of the handle 110 is adapted and sized to be received by the molding slots 134-146. As will be appreciated, the number of mization slots may vary, depending on the application. When the stem 112 of the handle 110 is placed in one of the indexing grooves 134-146, the handle 110 is held in the position defined by the respective groove.

Referring to Figures 4-8, the use and operation of the valve basket assembly 10 of the present invention will now be described. When it is desired to place the second end 94 of the valve 90 with respect to the mold 20, the index gate 130 is pivoted upwards, as shown in FIG. 8. This allows the movement of the handle 110 in the directions indicated by the arrows 122 and 124 in figure 8. This causes corresponding rotational movement of the movable disk 70. The movement of the rotary disk 70 causes the follower surface 82 of the movable disk 70 to slideably engage and travel along the cam surface 80 of the fixed disk 60. This causes movement of the movable disk 70 in the directions indicated by arrows 84 and 86 of FIG. 7. This causes corresponding vertical movement of valve 90 due to the operative connection of valve 90 with movable disk 70. Once the valve has been positioned with respect to the mold 20, the index gate 30 is lowered, as shown in Figure 4, so that the stem 112 of the handle 110 be received by one of the indexing slots 134-136. Placing the rod 112 in one of the indexing slots 134-146 keeps the rod 112, the movable disk 70 and the valve 90 in position. In a preferred embodiment, for example, the predetermined slope S of the cam surface 80 of the fixed disk 60 allows the movement in increments of the movable disk 70 and thereby the valve 90 in the directions indicated by the arrows 84 and 86 in increments of 0.004 inches (0.1016 mm). The increments can be indexed by the position of the stem 112 of the handle 110 in the indexing slots 134-146. For example, when the rod 112 is placed in the fourth indexing slot 140, the movable disk 70 and the valve 90 are in "neutral" positions. If the handle 110 is moved in the direction indicated by the arrow 122 in Figure 8 so that the stem 112 is positioned in the indexing slot machine 142, the movable disk 70, and thereby the valve 90, is raised 0.004 inches. (0.1016 mm) in the direction indicated by the arrow 84 in Figure 7. If the handle 110 is moved in the direction indicated by the arrow 124 in Figure 8, so that the stem 112 is placed in the third indexing slot 138, the movable disk 70, and with it the valve 90, will fall 0.004 inches (0.1016 mm) in the direction indicated by arrow 86 in figure 7. This allows the second end 94 of the valve 90 is placed easily, quickly and precisely with respect to the mold 120. The above detailed description of the present invention is given for explanatory purposes. It will be apparent to those skilled in the art that numerous changes and modifications can be made without departing from the scope of the invention. Consequently, the entirety of the foregoing description must be interpreted in an illustrative and non-limiting sense, the scope of the invention being defined solely by the appended claims.
