BUTTON OF THE TYMPAN.

An iron button with a female screw, screwed on a square shanked bolt, that goes through the bottom frame of the outer tympan, in wooden presses, and turns on the upper side of the inner tympan, to assist in keeping it tight in its place.

In very fine work also, when the paper is stout and heavy and large sheets, and it is not customary to fly the frisket, but to turn it down upon the paper before the tympan is turned down upon the form, a button is placed upon the lower frame of the outer tympan, which clasps the extreme end of the frisket, and confines the sheet of paper in its place on the tympan, and prevents it slipping down.
