• so that the ram outer ring is positively held in place by the cooperation of the first and second fingers, the frame center column, and the shifter post when either the pickup die or the crimp die is under the ram means.

A universal assembly machine comprising:

• a. a pickup die and a crimp die;
• b. ram means for operatively associating with the pickup die during a pickup stroke to assemble a flexible artwork to a shell, and with the crimp die during a crimp stroke to assemble the artwork and the shell to a back;
• c. first and second upstanding columns and a crown spanning and attached to the columns;
• d. a die table to which the pickup die and crimp die are mounted, the die table rotatably indexing about the first column to place the pickup die and the crimp die in operative association with the ram means;
• and
• e. a shifter post bidirectionally controlling the ram means between a pickup mode and a crimp mode in response to indexing the die table to place the pickup die and the crimp die in respective operative associations with the ram means,
• wherein the ram means comprises:
• i. a ram plate biased against the crown toward a retracted position;
• ii. a ram die fastened to the ram plate;
• and
• iii. a handle pivotally connected to the crown and engaging the ram plate, the ram plate and ram die advancing and retracting in response to pivoting of the handle.

• b. ram means for operatively associating with the pickup die during a pickup stroke to assemble a flexible artwork to a shell, and with the crimp die during a crimp stroke to assemble the artwork and the shell to a back;
• c. first and second upstanding columns and a crown spanning and attached to the columns;
• d. a die table to which the pickup die and crimp die are mounted, the die table rotatably indexing about the first column to place the pickup die and the crimp die in operative association with the ram means;
• and
• e. a shifter post bidirectionally controlling the ram means between a pickup mode and a crimp mode in response to indexing the die table to place the pickup die and the crimp die in respective operative associations with the ram means,
• wherein the ram means comprises a ram outer ring having first and second fingers jutting therefrom, the shifter post contacting the first finger and rotating the ram outer ring to the pickup mode in response to the die table indexing the pickup die into operative association with the ram means, the shifter post contacting the second finger and rotating the ram outer ring to the crimp mode in response to the die table indexing the crimp die into operative association with the ram means.

• b. ram means for operatively associating with the pickup die during a pickup stroke to assemble a flexible artwork to a shell, and with the crimp die during a crimp stroke to assemble the artwork and the shell to a back;
• c. first and second upstanding columns and a crown spanning and attached to the columns;
• d. a die table to which the pickup die and crimp die are mounted, the die table rotatably indexing about the first column to place the pickup die and the crimp die in operative association with the ram means;
• and
• e. a shifter post bidirectionally controlling the ram means between a pickup mode and a crimp mode in response to indexing the die table to place the pickup die and the crimp die in respective operative associations with the ram means, wherein the ram means comprises a ram outer ring having first and second fingers jutting therefrom, the shifter post contacting the first finger and rotating the ram outer ring to the pickup mode in response to the die table indexing the pickup die into operative association with the ram means, the shifter post contacting the second finger and rotating the ram outer ring to the crimp mode in response to the die table indexing the crimp die into operative association with the ram means, wherein:
• i. the shifter post is joined to the die table;
• ii. the die table indexes 180 degrees to place the pickup die and the crimp die into operative association with the ram means such that the shifter post is on opposite first and second sides of the first column when the pickup die and the crimp die are in the respective operative associations with the ram means;
• and
• iii. the shifter post is in contact with the first finger when the shifter post is on the first side of the first column, and the shifter post is in contact with the second finger when the shifter post is on the second side of the first column.
