Sorry, no etymologies found.
Attached to the upper end of the inner frame by hinges was a thin and narrow frame, called the "frisket," of the same length and width as the inner tympan frame.
If it works like it's supposed to, the liquid frisket I bought today will be my new friend.
If this were so, it could very well be that the chain or pulley or linkages to the back end were removed in the photo retouching because they were too difficult to cut around (if the manip was done as a collage) or to frisket out (if the manip was a double exposure process in a darkroom).
The sheet of paper was placed upon the blanket, and the cylinder then turned forward, drawing the frisket frame down with it, while the tapes, kept taut by the reel springs, adjusted themselves to the curvature of the cylinder and held the sheet upon it.
At the end of the cylinder and at equal distances along its circumference were hinged three frisket frames, each fitted with tapes having reel springs at one end.
When the type-bed and the frisket carrying the sheet of paper were in position under the platen, the latter was drawn downward to make the impression by means of a "toggle" joint which acted upon two strong rods, one on each side, and was then raised again by a counterbalance weight.
After the impression had been taken, the platen was screwed up, the bed "run out," the tympan frame and frisket lifted, and the printed sheet taken off.
When the sheets of paper had been placed upon the tympan frame, the frisket was folded down upon it, and the two were then turned down over the form of type.
On the next forward movement of the bed and the next one-third of a revolution of the cylinder, the impression was made, and on the next repetition of these movements, the sheet was taken off by hand, and the cylinder returned to its original position to have another sheet placed on the first frisket.
The threefold motion of the cylinders was retained, but the frisket frames were displaced, and tapes running over rollers and underneath the cylinders held the sheets against the impression surfaces.
