Care must be used in replacing the box to seat as high as it will go and have the washer on the screw so that it clamps the box bracket to the distributor beam. Turn upward on the handle of the screw.
The new distributor box bracket is provided with pins that fit in a groove in the distributor beam to prevent the box being placed in any other than the correct position.
FIRST ELEVATOR JAWS AND SLIDE
The first elevator slide is held in place by four gibs on the vise frame so that the jaws will stand parallel with the mold. The gibs are also used for adjusting the first elevator jaws so they will just clear the delivery and the intermediate channels. The slide is operated by cam No. 1, through the first elevator and the auxiliary levers and connecting link.
The first elevator jaws are attached to the top of the first elevator slide. They carry the line of matrices to the casting position and then to the second elevator. When the matrices have entered the first elevator jaws they are in position with their face toward the mold. The elevator slide travels down to the vise, the mold advances and the lower lugs of the matrices enter the groove of the mold, the elevator raises for alignment and lifts the line up against the aligning groove, or mold keeper, of the mold for casting.
As the first elevator jaws descend to the vise cap, the center screw in the top of the first elevator slide strikes on the vise cap and regulates the distance from the lugs of the matrices to the aligning groove in the mold when the mold slide advances.
There should be 1/64 of an inch space between the bottom of the center screw and vise cap when first elevator is lifted for alignment. If the center screw is not properly adjusted, when the mold advances the lower lugs on the matrices would be sheared. An entire font of matrices might be ruined in a very short time in this manner.
To test this adjustment, place a good matrix in the first elevator jaws, turn the machine until the adjusting screw is resting on the vise cap, disconnect the mold slide and bring the mold disk forward so the lug of the matrix enters the groove in the mold. Raise the elevator slide with the left hand, which raises the lug of the matrix against the aligning groove in the mold. At this point there should be 1/64 of an inch between the end of the center screw and the vise cap. If not, turn the screw with the right hand until it is resting on the vise cap. Then turn the screw to the left until it is approximately 1/64 of an inch from the vise cap.
On the older model machines this adjusting screw is ⅜ of an inch in diameter and has 16 threads to the inch. By turning the screw to the left one-quarter of a revolution, it allows the 1/64-inch adjustment. On all new machines the adjusting screw is ½ inch in diameter and has 12 threads to the inch. Turning the screw one-fifth of a revolution allows the 1/64-inch adjustment.
As the mold disk moves forward the elevator jaws raise for alignment, the lower lugs of the matrices being raised against the aligning groove in the mold. The locking stud blocks receive the mold disk locking studs so that the mold sets parallel with the side of the vise. The elevator should be adjusted so that the jaws will be parallel with the mold.
