Frisket Pins

Two iron pins that pass through the frisket joints and connect it with the tympan. They are made to slip in and out of the joints easily with the fingers, and are put in from the inside of the joints, so that the heads are opposite to each other. It is a common practice with pressmen, when they have occasion to take off the frisket, to lay the pins on the form. This ought never to be done; for I have known an impression pulled under these circumstances, at a good wooden press, without the frisket, and where the pins were forgot. The consequence was, the destruction of types, and the bedding in of the pins into the platen: — there was loss of types — loss of time in replacing them — the platen to be taken off and planed, with the expense of doing it, in addition to which it was reduced in thickness full a quarter of an inch, and the further loss of time while it was doing and hanging again, and justifying the head. They may always be safely laid within the chase between the quoins, where they can do no harm, and cannot roll off.
