s1 PAUL, MINNESOTA! PBINTING;IDEVICE IfOR BOOKBINDERS PRESS-MARKS.

To all whom it may concern 5 Be itknown that we, AUG ST GaNIER and CHARLES P. OLEsoN, citizens of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements inPrinting Devices for Bookbinders Press-Marks, of which the following is a specification.

Our invention relates to improvements in printing devlces forprlnting bookblnders" press marks upon the forms or signatures of a book while the same are being printed.

In bookbinding the order in which the folded setsof sheets, or signatures as they are called, are to be arranged is indicated by a signature number which is printed upon each sheet as the same goes through the press, so that when the sheets are folded into signatures for binding the signature numher will be at the bottom of the outside page of the signature. The signatures are then assembled in the order indicated by the successive numbers. In order to avoid the necessity of examining each of these numbers to see that the signatures are properly assembled a press mark is sometimes placed upon the back fold of each signature at a distance from the head of the signature which will vary according to the position the signature is to occupy in the bound volume, so that these marks will stand in regular gradations and form a broken line extending diagonally. across the folded back edges of the assembled signatures, and the absence of any mark or the presence of too many can be seen at a glance by a visual proof inspection of the back. These marks have been applied to the signatures after the same have been printed and folded,

but such subsequent application of the marks deprives them of any value in detecting inaccuracies or irregularities in printing'or folding the sheets, and does not entirely obviate thenecessity of examining the successive signature numbers to make sure that all those of the same number have been collected into their own pile.

It is the object of the present invention to provide improved means for accurately, and conveniently printing these signature marks upon the signature sheets as thejsame are-passed through the press and,

which is used for printing the'mark does not have to be removed from the chaseas the successive signatures are printed, but can be readily shifted and adjusted to the positi.onsrequired for the succeeding signa tures, and. whereby themark shall beso accurately placed as toenable the operator to detect errorscinfeeding the sheet through the press, or-in folding the same, by inspection of themarks upon the foldedback edge of the signatures." i

. More 'particularly 'thefinvention consists in the construction, combination, and arrangement of jparts hereinafter described and claimed; j

In the accompanying drawings representing. the preferred embodiment of the in- Z vention, Figure 1 is a-perspective view of the improved type holder with some parts broken away; Fig. 2 is a longitudinal section through the middle of a fragmentrof thetype holder; Fig. 3 isa perspective view of one of the sliding type; Figs.4 and 5 are perspective views of modified forms of type ends which can used forthe second and third rows of signatures, respectively; Fig.

6 is a detail of the spring pressed adjusting pinv for the type; and Fig. 7 is a perspective view of a pile ofv slgnatures assembled for b1nd1ng,show1ng press marks upon the back.

As shown in Fig.1, thetype holder com- I prises a bar 2having alongits longitudinal middle a slot 8 which is preferably widened or undercut at the base, so as to beT-shaped in section. Constructed to slide withii'ithis slot is atype a with a widened or flanged;

base 5 adapted to fit within the undercut channel in the .base of the slot. This type has a type face 6, of convenient length and width for the press mark to be printed.

Upon the face of the type holder are a sucg cession of spacing marks 7 arranged at a distance apart approximately equal to the length of the type face 6. The spaces between the spacing marks are numbered consecutively from One up as. a guide for setting the type. The type isheld in adjusted positions so that its face will register with any of the numbered spaces uponthe holder, by means ofa pin 8 which extends down through the type and is adaptedto fit holder and at-the other end against a shoulder 12 on the pin. The holes 9 are equal in number to the spaces upon the face of the holder, and are so positioned that the typefacewill register with one of the numbered spaces whenever the pin fits into a hole. The holder has at one end a spur headed extension screw l3whereby it can be made to fit the furniture of the chase.

In use,ithetype holder is placed within the frame or chase which carries the type for printingthe signature sheet, and made fast therein by means of the screw 13. The pin '8 of thetype is then drawn up against the pressure of its'spring until it emerges from the hole 9 and clears the bottom of the slot, thus leaving the type free to move. The'type is then moved along the slot until its face registers with the space bearing the same number as the signature number of the sheet to be printed. If the signature is tobe placed at the beginning of thebook, the type will be adjusted in the slot so that its face will register with the space numbered One on the holder. When the type has reached this position, the pin, if released, will spring down into the hole provided for the space numbered One, thereby locking the type firmly in the position at which it has been set. The type face for'the press mark can then be inked with the other type in thechase, and, as the sheets A are passed through the press, will print at the line of fold a mark 14 of the same length as the type face, or, in other words, of the same length as one of the spaces upon the holder. When the next succeeding signature sheets are tobe printed, the type will be moved back one space so that its face will register with the space numbered Two, and the "secondsheets will be printed as above described.

The holder is made preferably of the same length as the printed page, so that the press marksupon the backs of the signatures will extend in a continuous, but broken, line from the top of the volume to the bottom thereof. If, now, more signatures are required to complete the book, it will be necessary to begin over again at the topfor a second pile of signatures. In order to distinguish these 60 I signatures from those first placed, a type may be used which has two separated face -parts15,as illustrated in Fig. 4. If a third pile or row of'signatures becomes necessary, a type may be used which has three separated face parts 16, as shown in Fig. 5. In

this way it is possible to distinguish whether the signature belongs to the second or third pile, it being impossible to distinguish merely by the position of the mark with reference to the top of the page. In the drawings, 17 indicates the press mark made by the use of the two-faced type shown in Fig. 4:, while 18 indicates the press mark made by the use of the three-faced type shown in Fig. 5.
